Description

Broken tooth type re-crushed waste PVC plastic secondary utilization treatment device

Technical Field

The invention relates to the technical field of environment-friendly equipment, in particular to a tooth-breaking type re-grinding waste PVC plastic secondary utilization treatment device.

Background

PVC has been the most widely used plastic in the world and is used in a very wide range of applications. The product has wide application in building materials, industrial products, daily necessities, floor leathers, floor tiles, artificial leathers, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers and the like. The waste PVC can be reused after being reprocessed, so that on one hand, resources can be saved, and on the other hand, the environmental pollution can be avoided.

For example, CN 102794217B proposes a plastic pipe milling crusher, which mainly solves the technical problems that in the past, there are two main methods adopted in plastic pipe crushing at home and abroad: firstly, the pipe is shredded by a shredder and then is crushed by a crusher, and the method has the advantages of high required power, high noise and low yield; for example, polyethylene PE pipe with 800mm diameter is crushed, the total power of the two machines is 180kw, and the output of 8 hours is about 4 tons. Secondly, the pipe is sawed into sections, cut into strips, cut into blocks, thrown into a crusher to be crushed and then granulated, the mode has the advantages of much dust, high noise and low yield, PVC can be rapidly melted on one hand and can be rapidly mixed with other elements on the other hand because the PVC needs to be completely crushed after being processed again, but in the technical scheme, the effect is difficult to achieve only by a milling motor, in the cutting process, partial pipelines can cause the unqualified size due to the problem of the shape of the pipeline or the problem of position deviation in the cutting process, and the pipelines with the unqualified size need to be separately separated when being secondarily processed, so that the feeding is convenient, but the mechanism also does not have the function.
