Plastic regeneration process and plastic regeneration machine

Abstract

The invention discloses a plastic recycling process and a plastic recycling machine, which relate to the technical field of plastic recycling. It puts plastic into a container and heats and melts it; injects the melted plastic into an extruder and extrudes it; There can be two plastic containers, and the two containers are connected in series in sequence, and the plastic is heated in sections and multi-stages along the direction of entering the outflow container, and its temperature is increased successively; the feeding port of the container for putting in the plastic can be provided with a lock And seals, the discharge port can be provided with a regulating valve, the container can be provided with a water interlayer, relying on high-temperature water vapor to transfer heat to the plastic, and the melted plastic is extruded from the container. Compared with the prior art, the present invention solves the low efficiency and high energy consumption caused by the existing plastic recycling method and the plastic recycling machine used in this method, the screw and barrel of the plastic recycling machine are seriously worn, the screw Easy twisting leads to high failure rate, high maintenance cost and high production cost.

Description

technical field [0001] The invention relates to the technical field of plastic recycling, in particular to a plastic recycling method and a plastic recycling machine. Background technique [0002] At present, the method of plastic recycling is generally to wash the plastic, then put it into a plastic recycling machine to melt, and then extrude it from the head of the plastic recycling machine. The plastic recycling machine used to regenerate plastics in this way includes a barrel with a feed inlet, a screw inside the barrel, and a heating source outside the barrel. When the cleaned plastic is put into the feed port on the barrel, after starting the machine, with the rotation of the screw, the plastic is forced to the direction of the machine head by the thread, and the forward plastic raw material is received by the barrel on the one hand. The compression, shearing, stirring and other forces of the screw generate a lot of heat. On the other hand, it is heated by the heating...

AI Technical Summary

Problems solved by technology

[0003] The plastic recycling process and the plastic recycling machine provided by the present invention mainly solve the problems of low efficiency and high energy consumption caused by the existing plastic recycling method and the plastic recycling machine used in this method, and the problems of the plastic recycling machine. The screw and barrel are severely worn, and the screw is easily twisted, resulting in high failure rate, high maintenance costs, and high production costs.
