Waste thermosetting plastic regeneration device and regeneration process

Abstract

The invention discloses waste thermosetting plastic regeneration device and regeneration process in the technical field of the waste thermosetting plastic regeneration device and regeneration process. The device comprises a crushing box, wherein the left side of the crushing box is fixedly connected to a feeding plate, and the front side wall and the rear side wall of the crushing box are fixedly connected to mounting discs through a plurality of U-shaped connecting blocks. When thermosetting plastic is crushed every time by the device, a scraping plate continuously rotates in the crushing box, thermosetting plastic fragments with insufficient crushing granularity are scraped and brought up, when the scraping plate moves and passes through a first baffle and a second baffle to open the first baffle and the second baffle in advance in cooperation with a rotating mechanism and an opening and closing mechanism, the scraping plate can move circumferentially to perform continuous scraping action, so that plastic particles which are not crushed completely can be crushed for multiple times thoroughly, and the thermosetting plastic can be recycled completely.

Description

technical field [0001] The invention relates to the technical field of waste and old thermosetting plastic regeneration equipment and regeneration technology, in particular to a waste and old thermosetting plastic regeneration equipment and regeneration technology. Background technique [0002] Thermosetting plastics refer to a type of plastic in which the resin undergoes chemical changes during processing, the molecular structure changes from a linear structure before processing to a network crosslinked structure, and the product has the characteristics of insoluble and infusible. Commonly used thermosetting plastics include polyurethane, phenolic resin, epoxy resin, unsaturated polyester, melamine and urea-formaldehyde resin. There are many differences between thermosetting plastics and thermoplastics in performance. It has the advantages of high strength, good creep resistance, high heat resistance temperature, high processing dimensional accuracy and good arc resistance....

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a waste thermosetting plastic regeneration equipment and regeneration process to solve the above-mentioned background technology. After that, it can enter the grinding mechanism for grinding. The broken thermosetting plastics may not be completely broken into fragments that can pass through the filter after being filtered once. The thermosetting plastic fragments that cannot pass through the filter stay on the top of the filter. It affects the screening of subsequent thermosetting debris by the filter screen, and there is also the problem that the thermosetting plastic debris staying on the top of the filter screen cannot be completely recycled
