Waste organic glass extrusion splitter

Abstract

The invention relates to a waste organic glass extrusion splitter. The waste organic glass extrusion splitter comprises a cylinder; the cylinder is wrapped with a heating ring, and is divided into an extrusion cylinder and a gasification channel connected with each other from front to back; double extrusion screw rods engaged for conveying materials are arranged in the extrusion cylinder; any one extrusion screw rod or double extrusion screw rods are externally connected with motor drives; a waste organic glass feed port is formed in an inlet end of the extrusion cylinder; the tail end of the extrusion cylinder is communicated with the head end of the gasification cylinder; a gasification screw rod is arranged in the gasification cylinder, and is externally connected with a motor drive; the gasification cylinder is axially provided with more than one gasification ports; the pitches and the shaft diameters of screw rods on two sides of the gasification screw rod opposite to the gasification ports are gradually changed, and the pressure is lowered, so that surface gas in wastes and split MMA monomers are released out; more than one gasification ports are connected with a condenser and a collecting tank by a gasification pipe in sequence; and the tail end of the gasification cylinder is provided with a discharge port of residues incapable of splitting.

Description

technical field [0001] The invention relates to waste organic glass recycling equipment, in particular to a waste organic glass extrusion cracking machine. Background technique [0002] Plexiglass is widely used in various industries because of its smooth surface, bright colors, small specific gravity, high strength, corrosion resistance, moisture resistance, light resistance, good insulation performance, and good sound insulation. 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. In the existing pyrolysis recovery technology, the commonly used waste and old organic glass cracking reaction process is a batch reaction. The waste and old organic glass is directly put into the pyrolysis kettle heated by an open flame to be cracked manually. Ev...

AI Technical Summary

Problems solved by technology

In the existing pyrolysis recovery technology, the commonly used waste and old organic glass cracking reaction process is a batch reaction. The waste and old organic glass is directly put into the pyrolysis kettle heated by an open flame to be cracked manually. Even, the temperature is difficult to control, which will easily lead to over-cracking of methyl methacrylate monomer, reducing the final collection purity, product quality and yield, and the cracking kettle is prone to fouling and coking. When cleaning, it is necessary to open the lid of the cracking kettle and manually shovel the coke. Cleaning is difficult, labor-intensive, and manual coke cleaning is labor-intensive, the working environment is poor, and the tail gas remaining in the kettle during coke cleaning is easy to cause environmental pollution

In addition, due to intermittent production and low labor efficiency, cracking a certain amount of waste and old organic glass often requires many cracking kettles, which occupy a large area
