The longer the extinguishing time of charcoal, the more users can be trusted. When purchasing a charcoal machine, you want to consume high-quality charcoal. The performance of high-quality charcoal is the length of extinction time. When charcoal is extinguished for a long time, the amount will be reduced, and the cost can also be used sparingly. Therefore, as long as the charcoal that has been extinguished for a long time is more popular.

So what is the way to improve the extinction time of the charcoal consumed by the charcoal machine? Progress in the charcoal machine rod making machine using the forming pressure of the original parts, and then increase the density and strength of the rod. After the final carbonization temperature of the high carbonization furnace (or carbonization kiln), and slow down the heating and cooling rate, the produced carbon has high density and high hardness. Of course, the quality of the charcoal machine itself is also very important.

Good quality guarantees efficiency guarantees output and is capable of preventing unnecessary losses. Therefore, the purchase of charcoal machine should choose a professional manufacturer. With China’s attention to the environmental protection industry, various environmental protection products and equipment are constantly being produced. The new charcoal machine is one of them. The charcoal produced by the new charcoal machine is widely used and has good development prospects and stable development space, Is a good investment project for the majority of users.

The charcoal machine produces charcoal with a wide range of raw materials, low prices, inexhaustible and inexhaustible. Some raw materials do not even cost money, such as wood processing residues: sawdust, wood chips, bamboo chips, bark, board bark, etc. Firewood forest, forest logging residues: branches, tree roots, etc .; agricultural and forestry by-product wastes: chaff, walnut shells, chestnut shells and other fruit shells and cores.

1. Flatten the four feet of the corn thresher equipment to ensure stability and firmness. To reduce vibration.

2. If the motor is used for power, it must be checked whether the power cord is firmly connected, tightly sealed, and installed according to the ground wire.

3. Feed corn cobs continuously and evenly, and the feeding amount should be appropriate. If fed intermittently, it will affect production efficiency. Too much feeding will cause the machine to be stuck and overloaded, resulting in burnt motor and damaged equipment.

4. The water content of the threshed corn on the cob shall not exceed 20%. If the water content is too high, the normal threshing effect cannot be achieved.

5. Before the work is completed, the input corn cobs are completely removed and discharged, and the empty load is stopped, and it is forbidden to stop with load.

The corn peeling and threshing combined machine produced by our company includes upper and lower peeling and threshing combined machines and left and right combined peeling and threshing machines. The product has a compact structure and a small body. It adopts a unique design concept. The peeling and threshing are clean and need not be cleaned. High production efficiency, welcome new and old customers to buy.

Working principle of integrated corn peeling and threshing machine

When the corn thresher is working, the corn is fed from the feed port, the corn is hit by the rotor and the drum rotating at a high speed, the grain is separated by the screen hole, the corn cob is discharged from the tail of the machine, the corn silk, and the skin are from the tuyere discharge. The feed inlet is located at the upper part of the upper cover of the machine. The corn cob enters the threshing chamber through the feed inlet. In the threshing chamber, the high-speed rotating rotor hits the corn kernels and falls off. The corn kernels are separated through the screen hole. Corn kernels splash hurt.

The raw materials enter the drum chamber through the feed port, and the drum body peels off the corn hull through rotation, friction, squeezing and pushing, and the corn hull and corn cob are automatically discharged from their respective outlets. With this machine, the threshing efficiency is determined by the length and diameter of the drum. Users can choose this series of corn threshers reasonably according to their threshing efficiency. The hammer and spacer on the rotor are wearing parts, and their wear should be checked frequently. If necessary, they should be repaired or replaced to ensure the balance of the rotor; the screen is a wearing part. If the screen is damaged, please replace it with a new one.

After all, human labor is limited, and both physical and mental effects will be affected. Now, with the development of a full-automatic corn thresher, there is no need to worry about large areas of corn. The machine circulates back and forth in the middle of the corn. A large piece of corn immediately entered the car, which was a very magical thing.

To save physical labor and time loss, the magical power of corn thresher is vast!

Undoubtedly, the invention of crop technology has promoted the rapid advancement of the entire agriculture. The research and development of corn threshers have saved the labor force of farmers. Then, the 5 operation processes that need attention in the operation process of corn threshers :

1. Before the operation of the corn thresher, the roads and fields must be surveyed, and the dangerous sections and obstacles should be clearly marked.

2. When maintaining, overhauling, and troubleshooting the corn thresher, the power must be cut off and the engine is turned off; when performing mechanical maintenance or repair under the harvesting head, the harvesting head must be raised and supported with a safety bracket or cushion, Confirm safety before proceeding; open flame lighting is strictly prohibited when maintaining machinery at night or adding fuel.

3. When unloading grain, people are not allowed to enter the granary, iron tools and other tools are not allowed to enter the granary, and the grain receiving personnel are not allowed to extend their hands into the grain outlet.

4. Raise the header to the highest position to lock it when the plot is transferred. It is strictly forbidden to use the header to carry the goods.

5. Check whether the seats and backrests of the grain-receiving personnel are firm and reliable at any time.

Charcoal machine equipment performance has the following aspects:

1. High production capacity, low price, and low power consumption;

2. Strong material applicability: suitable for the molding of various biomass raw materials, the straw length is from powder to 50mm, and the moisture content is 5-30%, which can be processed and formed;

3. Electric heating function: Fully automatic electric heating device can adjust the dry humidity of the material to solve the problem of blockage and non-formation;

4. Automatic adjustment function of pressure roller: the principle of two-way rotation of thrust bearing is used to automatically adjust the pressure angle, so that the material is not crowded and the machine is not stuffy, and the stability of the discharge molding is ensured.

5. Simple operation and convenient use: high degree of automation, less labor, only 3 people, manual feeding or conveyor feeding can be used. Pay attention to the humidity of the raw materials, whether the equipment is not firm during the installation process and the strength of the produced product.

The quality of charcoal can only be proposed according to different uses. Usually, we mainly measure the quality of charcoal from the moisture content, volatile content, ash content, fixed carbon content and calorific value of charcoal.

1. Moisture content Because charcoal is a highly absorbing substance, it will absorb moisture in the air during the stacking process and increase its moisture content. Therefore, the moisture content of charcoal has no effect on its own quality. It is nothing more than the customer’s request that the lower the moisture content of charcoal, the better, in order to increase its economic value. Generally speaking, the moisture content of newly-fired charcoal is less than 3%.

2. Volatile fraction (volatile matter content) The content of volatile matter (material) depends on the carbonization temperature. According to different uses, we can burn low and medium temperature charcoal and high-temperature charcoal. The former emits volatiles such as CO, CO2, H2, CH4 and gaseous carbohydrates during calcination at high temperature, and its content is generally 12-20%. The above-mentioned volatile matter released by high-temperature carbon is less, and its content is generally less than 5%.

3. Ash content (ash content) Ash is the white or pink material remaining after the charcoal is completely burned, which is what we usually call ash. Its size directly affects the use and economic value of charcoal. For example, straw, rice husks, and other substances contain large amounts of ash and are not easy to fall off during combustion, resulting in low temperature during combustion, which is not suitable for people’s life and industrial carbon. Of course, people hope that the smaller the ash content of charcoal, the better, in order to expand its use. The ash content of charcoal will vary with the carbonization process and temperature. However, as far as wood or its scraps are concerned, the difference in ash content after char formation is not large. Generally speaking, under the same conditions as above, the charcoal-fired by broad-leaved forests is higher than that of coniferous forests, and the raw materials with a large bark ratio The charcoal ash content are also relatively large. Common charcoal ash content is 1 to 4%.

4. Carbon content The carbon content of charcoal will change with the variety of raw materials and carbonization temperature. Generally speaking, the hard mixed wood has a higher carbon content than the latter at the same carbonization temperature compared to poplar, tung wood and other low-density wood. The carbonization of the same raw material at high temperatures is higher than that at low temperatures. Usually, the carbon content of charcoal is less than 75%, we take pine as an example when the carbonization temperature reaches 380 ℃, its carbon content is 76% when the temperature reaches 500 ℃, the carbon content reaches 85% when the temperature reaches 600 ~ 700 At ℃, the carbon content reaches 92%.

5. Calorific value The energy released per kilogram of charcoal under specific conditions is expressed in calories. The calorific value of charcoal is directly related to the carbonization temperature and holding time. Under the same carbonization temperature and holding time, the calorific value of different raw materials is different. Generally speaking, the carbonization temperature is high, the holding time is long, the carbon content is also large, and the calorific value is naturally high. When the carbonization temperature is less than 450 ℃, the calorific value of charcoal made from wood and its corner waste is usually between 6500 and 7000 kcal/kg, and the calorific value of straw and rice husk char is generally around 6000 kcal/kg. When the carbonization temperature is greater than 600 ℃, the calorific value of the carbon made from the above materials can be increased by 500-1000 kcal.

Theory and practice have proved that: dry raw materials, qualified propellers, and proper charcoal rod making temperature are the three major factors for producing good rods.

1. The humidity of raw materials

The bar requires high moisture content of raw materials, and the moisture content of raw materials is generally between 5% and 12%. If the moisture content is less than 5%, the raw material conversion and viscosity are poor, the rod is not strong; if the moisture content is greater than 12%, the rod is soft and easy to bend, and the density is small.

Usually, fresh materials (such as fresh bamboo, raw branches, etc.) contain about 50% water and need to be dried 1 to 2 times with a dryer. If the raw materials are dried in the open air or baked in the sun for 1-2 days, the number of drying can be reduced by one. In any case, we have to dry the raw materials more than once to meet the requirements of rod making.

How to identify the degree of dryness and wetness of raw materials? Generally speaking, we can make a rough identification by seeing and feeling. This approach is feasible as long as we accumulate experience. First of all, we touch the shell of the separator that is working, its temperature makes the hands feel hot; secondly, we see the color of the material that has just come out, and it needs to be yellow; finally, we grab a handful of the material that has just come out, and rub it into the ball with the palm, And then let go suddenly, requiring all the raw materials to be scattered. If the above requirements are met at the same time, it can be considered that the raw materials meet the requirements, of course, the final inspection is based on the rod making machine. If the thruster is normal and the salary rod produced meets the product quality requirements, the moisture content is within the normal range.

2. Propeller

Whether the thruster is qualified also determines whether the quality of the salary rod is qualified or not? The thruster is a wearing part, and the friction force generated by the contact of the top part with the raw material during the high-speed rotation causes the end face to wear seriously. In the case where the angle of the end face becomes smaller or the contact surface becomes rough and spotty, the rod produced will not meet the requirements, or even produce a rod. At this time, the thruster should be repaired according to the method taught by the manufacturer’s technicians to meet the technical requirements. As long as the operators (or maintenance personnel) practice and explore frequently, it is easy to master.

3. The working temperature of charcoal rod making machine

The temperature of the forming cylinder of the rod making machine is generally controlled at 260 ℃-320 ℃ is more appropriate. The temperature is mainly determined by the raw materials. First of all, we should know that the purpose of heating raw materials is to soften lignin and increase viscosity for high-pressure molding. If the temperature is too high, the raw material softens excessively, and although the rod is produced at a fast speed, the rod is not strong and becomes soft. If the temperature is too low, the viscosity of the raw material is poor, the rod is not strong, and it is easy to form fault cracks. Therefore, we have to repeatedly explore the temperature range of the rod. Generally speaking, the temperature for making bamboo and wood raw materials is relatively low, preferably 260 ℃ -280 ℃, hardwood sawdust controlled at 280 ℃ -300 ℃, straw and rice husk can choose 300 ℃ -320 ℃. Of course, the choice of temperature also has to take into account the actual moisture content of the raw materials. Using the same raw material to make rods, the temperature is also different, mainly depends on the flexible control of the operator. In addition, the color of the outer surface of the rod does not need to be too dark, just brown and black.

1. Length of charcoal: Charcoal packing length should be more than 5 cm, and the length limit is limited to the length of the carton.

2. Diameter (shrinkage) of charcoal: At present, most domestic charcoal equipment manufacturers adopt the standard of 5 cm diameter forming sleeves, so the diameter of the finished charcoal should be below 4 cm, and the optimal shrinkage size is 3.5-3.8. The resistance value is also based on the charcoal content and shrinkage of the charcoal. Export carbon has this test standard.

3. Color of charcoal: The color of charcoal should be black and shiny. From the appearance, the charcoal is pure black. If the color is black, the tapping sound is not crisp enough, which means that the water is too heavy. Break the charcoal and observe the color of the cross-section should be clearer. If there is yellowing, it means that there are many impurities in the charcoal, and the ash content and volatile content will naturally exceed the standard; or the carbonization process is not standard, the charcoal has smoke and smell (the charcoal may not have a smoke, but the smoke must have a smell) This is also the most obvious phenomenon of incomplete carbonization.

4. Hardness of charcoal: The carbon stick is held vertically with one hand, and the thumb cannot be easily broken. The better the hardness, the better the quality of the charcoal. Charcoal allows a small number of cracks and does not affect the quality of charcoal. However, if the crack is too large, it means that the density of the semi-finished wood rod is not good or the oxygen supply during the carbonization process is too exciting and too large, so the crack cannot be completely contracted. Pick up two pieces of charcoal and collide, it can make a crisp metallic sound.

The quality of charcoal can be simply judged by the charcoal shrinkage, color, hardness, cracks and presence or absence of steel tone. This is also one of the criteria for distinguishing between high-temperature charcoal and low-temperature charcoal. The higher the above standard requirements, the longer the burning time of the kiln, and the higher the furnace temperature requirements, the more serious the charcoal burning loss, the lower the natural charcoal yield.

High-quality machine-made charcoal can not only have a high selling price but also more easily welcomed by the market. Raw materials for processing high-quality machine-made charcoal can be produced after selection and drying after entering the factory. The key is that the moisture content of the drying must be reduced to between 12% and 6% before making rods. This is very important for the selection of the dryer, which has higher requirements. It is necessary to dry the raw material containing 35% water to about 10% at a time.

For beginners, they often walk into a misunderstanding that the molding machine cannot be molded. The cracks, weight, and density of the raw material rods after molding will be mistaken for bad molding machines. Ignoring the role of the dryer, whether the moisture content of the raw material is qualified is closely related to the quality of the molding. Drying is the prerequisite, and molding is the latter. Therefore, the drying index determines the forming and quality, which is relatively important.
