Carbonization and activation are two crucial steps in the production of biochar. Carbonization is the process of converting biomass raw materials into char at high temperatures, while activation involves treating the char using specific methods to increase its pore structure and improve its adsorption capacity and activity.

A second motor is mounted on the top of the fixing plate, and a lead screw is rotatably connected to the upper surface of the base plate. The upper end of the lead screw passes through the fixing plate and is fixedly connected to the output shaft of the second motor. This utility model, through the cooperation of the vertical rod, the second motor, the lead screw, the rectangular housing, and the storage box, solves the problems of existing integrated furnaces for activated carbon activation and carbonization where the feed hopper is positioned too high, making feeding inconvenient, and manual feeding is time-consuming, labor-intensive, inefficient, and poses certain safety risks.

[0004] In existing technologies, during the use of integrated furnaces, it is inconvenient to seal the feed hopper after material addition, allowing heat from inside the furnace to escape through the feed hopper, affecting the furnace's heating efficiency and causing flue gas to be emitted, polluting the external environment. Therefore, improvements are needed. Utility Model Content

[0009] Preferably, one end of the first spring is fixedly connected to the arc-shaped block, and the other end of the first spring is fixedly connected to the cover plate. By designing the first spring, the force of the first spring can be applied to the arc-shaped block.

[0010] Preferably, the exhaust mechanism includes a slide rod, which is slidably sleeved inside the fixed base. A second spring is installed inside the fixed base. A fixed rod is fixedly connected to the outer side of the slide rod. A stop block is fixedly connected to the top of the fixed rod. The stop block is slidably connected to the fixed base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the design of a motor, where the output of the motor can drive the rotating shaft and rotating block to rotate, which in turn can drive the cover plate to rotate. After the cover plate rotates, the arc-shaped block can be inserted into the arc-shaped groove to connect and fix the cover plate to the feed hopper, thereby sealing the feed hopper. This prevents heat loss during furnace operation from affecting the heating effect and also prevents the spread of flue gas from polluting the environment.

[0015] 2. By designing a fixed base, this utility model allows gas to enter the fixed base when the internal gas pressure of the furnace is high. Under the action of the filter screen and filter element, the flue gas can be filtered and purified. Subsequently, the gas can push the baffle to move up and separate from the fixed base. At this time, the purified gas can be discharged through the fixed base, thereby achieving the purpose of depressurizing the inside of the furnace and avoiding danger caused by high gas pressure.

A second spring 92 is installed inside the fixed base 11. One end of the second spring 92 is fixedly connected to the slide rod 91, and the other end is fixedly connected to the fixed base 11.

Subsequently, the gas will push the baffle 98 to move upward, the baffle 98 will drive the connecting rod 97 to move upward, the connecting rod 97 will drive the stop block 94 to move upward, the stop block 94 will drive the fixed rod 93 to move upward, the fixed rod 93 will drive the sliding rod 91 to move upward, and the sliding rod 91 will squeeze the second spring 92. At this time, the baffle 98 will slide out from the fixed seat 11, and then the gas can be discharged through the fixed seat 11, achieving the purpose of depressurizing the inside of the furnace body 1 and avoiding danger caused by high air pressure.
