Carbonization of coconut shell requires attention to temperature and humidity

Continuous carbonization furnace, when the coconut shell is carbonized, it must first be crushed and crushed to what extent. It can be determined according to the customer’s needs. The next step is drying. Drying is also very important. The general carbonized raw material is carbonized. When it is dry, otherwise, the effect of carbonization is not good, the drying degree of coconut shell is about 15%-20% of water, it is not too dry. After drying, it is carbonized. It is also very important. If the carbonization is not well mastered, it may be abandoned, turned into ash, or not charred. At this time, the use of the carbonization furnace is very important. How to operate it? There are several points to note.
1 Feeding of the feeding machine should be carried out according to the material inlet of the carbonizing machine. The falling condition starts and closes the feeding machine to replenish the carbonized material. The material of the lower feeding port cannot be piled up too. The material in the carbonizing tube is recommended to be kept at about 2/3.
2 The speed of the carbonization machine should be adjusted according to the carbon effect, and the spindle speed should be properly adjusted to ensure the carbon yield. (The spindle speed can be adjusted)
3 When there is smoke overflow at the shaft seat at both ends of the rotating shaft, the sealing gland bolt should be pressed in time after the shift, and the asbestos packing strip of the sealing material should be replaced if necessary.

Knowing how to operate, then the next step is the control of the temperature, the burner of the burner is sprayed, the carbonization tube is heated, the thermocouple is extended in the furnace body, and the space inside the furnace is displayed on the temperature control instrument on the panel of the control cabinet through the wire. temperature. (The actual temperature inside the carbonization tube will be 200~300° higher than the measured temperature in the furnace.) Environmentally friendly carbonization equipment, heated in the furnace for 15-20 minutes. When the temperature reaches 550-600 degrees, press the start button of the loading machine, the screw in the screw machine rotates, and the feeding of the feeding machine starts feeding. The carbonized shell material will rotate along the spiral of the screw machine. The pipe body climbs the material to the feed port above the carbonization machine.

When the coconut shell material is filled up with the inlet of the carbonization machine, press the carbonization furnace start button, press the red switch on the electromagnetic governor to the ON position, and slowly rotate the speed control knob to make the governor indicate the deflection pointer. , indicating that about 500-600 rpm (suitable for coconut shell), the auger of the carbonization machine is rotated by the spiral, pushing the material forward, stirring, and moving, in the first and second carbonization tubes in the top and bottom. Pre-drying, the water in the precipitate is discharged through the exhaust pipe. The chimney is discharged into the air, and the material is in the pipe. When one or two pipes are dried into the third pipe, the water has been deposited and cleaned. During the low-temperature carbonization stage, after continuous advancement, movement, and agitation, when entering the fourth tube, the material is turned, stirred, propelled, and moved through a distance in the high-temperature tube body to complete the carbon from the bottom temperature to the high temperature. During the carbon conversion process, the high-temperature carbon produced is finally discharged from the discharge port of the carbonization machine to the inlet of the water jacket type cooling and unloading machine, and the high-temperature carbon powder of the unloading machine tube is cooled and cooled by the cooling water surrounding the pipe body, and finally From the unloading machine discharge port Toner and soot after cooling, such as previously described, again and again, continuously working to complete the whole process of carbonization of coconut shell products.
