Benefits of technology

This patented technology helps prevent damage or defective product by removing metals that may be harmful when they enter another step during production. By having this system installed on an existing machine used for producing plastisol materials, it improves overall efficiency while reducing costs associated therewith.

Problems solved by technology

The problem with current methods for processing waste materials made from plastisolymerized polyethylene terephthlate (PET) has been that they may contain metals or other substances which could harm downstream processes such as injection molding machines during production. This would result in lowered efficiency and reduced durability of products produced therefrom.

Abstract

The invention discloses a filtration type single screw extruder. The filtration type single screw extruder comprises a machine body, and an extrusion channel is arranged inside the machine body; an extrusion screw is arranged inside the extrusion channel; a feed hopper which communicates with the extrusion channel is arranged on the extrusion channel; heating devices used for heating materials are further arranged inside the machine body; a filter device is arranged at an outlet end of the extrusion channel; the filter device comprises a shell; a filter element is arranged inside the shell; a feeding cavity and a discharge cavity are respectively arranged at the two ends of the filter element; the feeding cavity communicates with the extrusion channel; and a discharge hole is formed in the discharge cavity. According to the filtration type single screw extruder, the filter device is arranged at the outlet end of the extrusion channel, after the materials pass through the extrusion channel to heat plastic and are extruded to the filter device through the extrusion screw, metallic and nonmetallic impurities in the materials can be filtered out under the action of the filter element, the metallic and nonmetallic impurities are prevented from entering the follow-up procedures, and the quality of a plastic product is improved.
