A kind of recycling method of waste organic glass

Abstract

The invention belongs to the technical field of plexiglass recovery, and specifically relates to a method for recycling waste plexiglass. The method uses cracking equipment, and the cracking equipment includes a furnace body, a stirring motor, a feeding module and a slag extractor. One side of the furnace body is There is an electric burner at the bottom, and a furnace in the furnace body. The stirring motor is fixedly connected to the stirring shaft through the gearbox; the stirring motor is set on the top of the furnace; the stirring shaft runs through the furnace and enters the furnace; Connected; there is a storage tank under the condenser; the bottom of the slag discharger is connected to the water tank through a pipe; the feeding module is installed in the upper right corner of the furnace body; the feeding module includes a feeding box, a driving motor, a driving roller, and a driven roller , cams, airbags, curved guides, mounting plates, blowing heads and automatic doors. In the present invention, the organic glass particles are projected to the middle and upper part of the furnace through the air bag, so that the organic glass particles are evenly dispersed, and the raw materials are not piled up in the furnace to cause insufficient reaction and affect the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of plexiglass recycling, in particular to a method for recycling waste plexiglass. Background technique [0002] Plexiglass composed of polymethyl methacrylate is widely used in various industries. However, using waste organic glass to crack and regenerate to obtain methyl methacrylate monomer to realize the recycling of organic glass is in line with the policy of circular economy and has good environmental, economic and social benefits, so it has developed rapidly in our country. [0003] In the prior art, some technical solutions of organic glass continuous cracking devices have also appeared. For example, a Chinese patent with application number 2016206959990 discloses an environmentally friendly continuous cracking device for waste organic glass plastics, including a furnace body, a stirring drive motor, a feeder and slag extractor, the stirring drive motor is fixedly connected to the stirring shaft thr...

AI Technical Summary

Problems solved by technology

[0004] This technical solution can realize the continuous cracking of plexiglass, and the temperature, feeding and slag discharge can be controlled and adjusted. However, the raw material supply device of this solution makes the raw materials concentrate in the local position of the furnace body, resulting in the accumulation and distribution of raw materials. Inhomogeneity, which affects the efficiency of the cleavage reaction
