Outward rotation type waste rubber and plastic thermal cracking equipment

Abstract

The invention discloses outward rotation type waste rubber and plastic thermal cracking equipment, and belongs to the field of waste rubber and plastic thermal cracking equipment. The equipment comprises an outward rotation type reaction kettle and a mechanical sealing assembly, and a discharge port of the reaction kettle is of a reducing structure; the mechanical sealing assembly comprises a mechanical sealing moving ring compensator, a moving ring fixing ring, a friction moving ring, a mechanical sealing static ring compensator, a friction static ring, a first spring and a second spring; the friction moving ring is mounted in a groove formed in the right side of the moving ring fixing ring and rotates along with the reaction kettle; the first spring sleeves a second bolt; the second spring sleeves a first bolt; and the friction moving ring is rotationally connected with the friction static ring. The equipment is applied to thermal cracking of waste rubber and plastic, solves the technical problems of low thermal cracking efficiency and frequent shutdown caused by coking of a kettle body, insufficient pyrolysis and poor sealing performance of existing thermal cracking equipment, and has the characteristics of high thermal cracking efficiency, thorough cracking, good sealing performance and high safety.

Description

technical field [0001] The invention belongs to the field of waste rubber and plastic pyrolysis equipment, in particular to an externally rotating waste rubber and plastic pyrolysis equipment. Background technique [0002] The popularity of cars not only facilitates people's lives, but also makes great contributions to industrial development. But after the service life, the disposal of waste cars, especially waste tires and waste plastics has become a problem that seriously affects the environment. Waste tires and waste plastics are artificially synthesized organic matter that cannot be degraded naturally. If they are not recycled properly, they will not only cause huge damage to the environment, but also waste resources. According to the data, there are about 400 million waste tires in my country every year, and about 14 million tons of waste plastics are not recycled every year. The recycling rate is only 25%, and the direct waste of resources is as high as 28 billion yua...
