[0024] Working principle: When in use, the operator opens the material cover 12 and inputs the garbage to be processed into the carbonization furnace body 10 through the feed pipe 11, and then closes the material cover 12 again. At this time, the operator starts the servo motor 4 and the electric heating tube 9. After the electric heating tube 9 is powered on, it will heat the carbonization furnace body 10, increasing the temperature of the carbonization furnace body 10. The carbonization furnace body 10 will then heat and carbonize the garbage. The servo motor 4 drives the driving gear 5 to rotate through the output end. The driving gear 5 then drives the heat preservation cylinder 6 to rotate through the gear ring 7. The heat preservation cylinder 6 will drive the carbonization furnace body 10 to rotate. The carbonization furnace body 10 will then drive the raw materials inside it to keep turning, making the garbage evenly heated, improving the carbonization effect of the carbonization furnace body 10.
