Abstract

The invention discloses commingled plastic quality-sorting and appreciating equipment. The equipment mainly comprises a driving motor, a speed reducer, a shaft coupler, a screw rod, a machine cylinder, a heating system, an exhausting system, a filter plate, a hand push rod, a mesh cleaning plate, a melt discharging pump, a filter screen, an extrusion die head, a solid phase discharging hole and the like, wherein the driving motor, the speed reducer and the shaft coupler form a transmission system of the equipment; the screw rod is arranged inside the machine cylinder and is connected with the transmission system; the filter plate and the machine cylinder are combined to form a hollow cylinder; a plurality of mesh cleaning rods capable of vertically moving up and down are arranged on the mesh cleaning plate; the hand push rod is integrally connected with the mesh cleaning plate; the solid phase discharging hole is positioned at the tail end of the screw rod and extends out of the side surface of the equipment via a pipeline; the melt discharging pump is connected with the extrusion die head. By utilizing the commingled plastic quality-sorting and appreciating equipment, separation and extrusion pelletization of commingled plastic can be simultaneously performed.

Description

technical field [0001] The invention belongs to the field of plastic machinery equipment, and relates to a device for classifying and adding value to mixed plastics, in particular to a method of heating and extruding a screw extruder to mix low-melting-point components and high-melting-point components in mixed plastics. The solid-liquid separation is carried out, and the molten material is further extruded and granulated to realize the separation and value-added of mixed plastics. Background technique [0002] Nowadays, with the rapid development of the plastics industry, the output of various plastics in my country is increasing year by year, so the amount of waste plastics is also increasing. The composition of waste plastics is often not single, but composed of several kinds of plastics mixed with each other, which restricts the way of high-value utilization of waste plastics. Therefore, the sorting of waste mixed plastics is a key link in the recycling of waste plastic...
