When carbon powder is uniformly scraped into the carbon outlet 27 by the carbon scraper, the electric valve 52 of the carbon outlet is automatically opened, and the electric slide rail drives the carbon outlet driving motor 54 to move forwards, so that when the carbon outlet screw rod 55 extends into a set position in the carbon outlet 27, the carbon outlet driving motor 54 drives the carbon outlet screw rod 55 to rotate to discharge carbon, and the carbon powder enters the carbon powder cooling barrel 57 through the carbon outlet pipe 56. The carbon powder is connected with a carbon powder cooling barrel 57 through a carbon outlet pipe 56 by using a flange (the middle is prevented from flowing by using a high-temperature-resistant metal graphite gasket), and an air outlet valve 5-16 is opened before the carbon powder enters the carbon powder, so that air is discharged. The toner cooling barrel 57 includes a first barrel wall and a second barrel wall, which have a space, and a circulating water cooling is provided in the space to ensure that the internal toner is cooled to normal temperature in a set time. In order to ensure uniform cooling of the carbon powder in the carbon powder cooling barrel 57, a stirring device is arranged, the stirring device comprises an explosion-proof motor, the stirring shaft is driven to rotate through a shaft coupling, 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 a mechanical seal (cooled by circulating water), and the carbon powder cooling barrel is connected by a flange (the middle of the carbon powder cooling barrel is prevented from flowing by a high-temperature-resistant metal graphite gasket). When carbon is discharged within the set time in the reaction kettle, the electric slide rail 53 acts reversely, so that the carbon discharge screw rod 55 exits 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 automatically opened, and the carbon powder enters the closed carbon storage barrel through the dragon for storage.
According to the waste plastic treatment equipment, 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 meanwhile, the oil refining efficiency is improved. In addition, the structural arrangement between the reaction kettle and the catalytic tank enables the reaction to be more sufficient, and the oil gas conversion rate is improved.
According to the waste plastic treatment equipment, before the oil gas enters the first oil storage tank 9, the oil gas enters the dust removal tower, so that the separation of the oil gas and carbon powder can be further realized, and the separation precision is ensured.
According to the waste plastic treatment equipment, the electric valve is arranged at the carbon outlet 27, and the carbon outlet screw rod is extended into the carbon outlet to carry out carbon outlet operation when carbon outlet is needed.
The waste plastic treatment equipment disclosed by the invention is used for treating waste plastic to form separated carbon powder, oil and combustible gas, so that the pollution is prevented and the production energy is realized.
