Because it contains a large amount of calcium carbonate component, stone paper is easy to decompose under natural conditions, but the polyethylene component contained in it is difficult to be degraded by nature, and the recycling problem of stone paper needs to be solved. Because the existing market is relatively small, there is basically no device specially used for recycling and processing stone paper on the market at present, so it is necessary to design a stone paper recycling and cracking device.

[0004] To achieve the above object, the utility model adopts the following technical scheme: a stone paper recycling and cracking device, which comprises a vertically arranged cracking cylinder, a stirring structure arranged in the cracking cylinder, and a material inlet and outlet structure arranged on the cracking cylinder.

[0005] A power module is arranged outside the cracking cylinder and is in driving connection with the top of the stirring structure.

[0006] The material inlet and outlet structure comprises a feeding port fixedly connected with the cracking cylinder and a discharge structure. An electromagnetic induction heating module is arranged outside the cracking cylinder.

[0007] Further, the cracking cylinder comprises a vertically placed cylinder, an upper head detachably connected with the top of the cylinder, and a lower head detachably connected with the bottom of the cylinder.

[0008] Further, the feeding port is connected with the cylinder.

[0009] Further, the discharge structure comprises a gas outlet for discharging cracking gas and a slag discharge port for discharging solid or powder, and the slag discharge port is connected with the lower head.

[0010] Further, the gas outlet is connected with the upper head, and the gas outlet is arranged at a distance from the feeding port.

[0011] Further, the stirring structure comprises a vertical shaft and a stirring shaft arranged outside the vertical shaft in a spiral shape. The power module comprises a speed reducer, and the speed reducer is in driving connection with the top of the vertical shaft.

[0012] Furthermore, at least one pusher plate is provided at the lower part of the main shaft; a support is provided on the outside of the pyrolysis cylinder.

[0013] The beneficial effects of this utility model are as follows: By setting a stirring structure and a pushing structure inside the cylinder, and setting an electromagnetic induction heating module outside the cylinder, the purpose of recycling pyrolyzed stone paper is achieved. The stone paper is decomposed into solid powder and gas, which are collected separately. Existing devices for recycling stone paper generally only have 40% of the original mass after processing. However, experiments have shown that after pyrolyzing stone paper using this device, the solid component accounts for more than 80% of the original mass, thus improving the recycling rate. The pushing plate is set to discharge the pyrolyzed powder from the cylinder in a timely manner, preventing the processed powder from accumulating at the bottom of the cylinder and causing blockage.
