The carbon powder is connected with a carbon powder cooling barrel 57 through a carbon outlet pipe 56 by a flange (the middle part is prevented from flowing by a high-temperature resistant metal graphite gasket), and before entering the carbon powder, air outlet valves 5-16 are opened to discharge air. The toner cooling barrel 57 includes a first barrel wall and a second barrel wall, the first barrel wall and the second barrel wall have a gap, and circulating water cooling is provided in the gap to ensure that the toner inside is cooled to normal temperature within a set time. In order to ensure that the carbon powder inside is uniformly cooled, the carbon powder cooling barrel 57 is provided with a stirring device, the stirring device comprises an explosion-proof motor, a stirring shaft is driven by a coupler to rotate, a plurality of stirring blades (different in length) are arranged on the stirring shaft, the upper part of the carbon powder cooling barrel and the stirring shaft are sealed by mechanical seal (cooled by circulating water) and connected by a flange (the middle part is prevented from flowing by a high-temperature resistant metal graphite gasket). When carbon discharging in the reaction kettle is completed within a set time, the electric slide rail 53 reversely moves, so that the carbon discharging screw rod 55 exits from the reaction kettle, and the electric valve 52 is closed. When the carbon powder cooling barrel 57 is cooled for a set time, the carbon valve 571 is opened automatically, and the carbon powder enters the closed carbon storage barrel through the flood dragon for storage.

According to the waste plastic treatment equipment disclosed by the invention, in the reaction process of the reaction kettle, oil gas, carbon powder and other particles can be effectively separated, so that the purity of subsequent oil refining is improved, and the oil refining efficiency is improved. In addition, structural arrangement between reation kettle and the catalytic tank makes the reaction more abundant for oil gas conversion improves.

The waste plastic treatment equipment of the invention enters the dust removal tower before the oil gas enters the first oil storage tank 9, thus further realizing the separation of the oil gas and the carbon powder and ensuring the separation precision.

According to the waste plastic treatment equipment, the electric valve is arranged at the carbon outlet 27, and the carbon outlet screw rod extends into the carbon outlet to perform carbon outlet operation when carbon outlet is needed.

The waste plastic processing equipment processes waste plastic to form separated carbon powder, oil and combustible gas, thereby realizing energy production while preventing pollution.

The above description is only one embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
