Processing mechanism for preliminary secondary machining of waste PVC (polyvinyl chloride) plastic water pipes

Abstract

The invention relates to the technical field of environmental protection equipment, in particular to a processing mechanism for preliminary secondary machining of waste PVC (polyvinyl chloride) plastic water pipes. A technical problem to be solved by the invention is that PVC plastic is not convenient for discharging, briquetting and packing. In order to solve the technical problem, the inventionprovides a processing mechanism for preliminary secondary machining of waste PVC plastic water pipes, which comprises a box, wherein a feeding pipe is plugged inside the opening of the top of the box,a preliminary strip cutting mechanism is fixedly connected to one side of the inside wall of the box, a granulating mechanism is arranged on the bottom of the inside wall of the box, the output end of the granulating mechanism is in driving connection with the output end of the preliminary strip cutting mechanism, and a material spreading mechanism is in bell and spigot joint with the granulatingmechanism. In case of rotation, a lower granulating bulge on the granulating mechanism disclosed by the invention rotates, with use of an upper granulating bulge, segmented plastic strips can be granulated, and a dispersion cone block arranged on the top of a rotary table can facilitate diffusion of falling plastic strips to four sides, so as to facilitate discharging and enable the plastic to enter granulating step smoothly.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a treatment mechanism for pre-secondary processing of waste PVC plastic water pipes. Background technique [0002] The natural color of PVC plastic is light yellow translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. And lower than polypropylene, there will be whitening at the inflection. In real life, too many PVC pipes will be discarded after a period of use. In order to solve resources, these resources are generally recycled and used for secondary use. [0003] For example CN 106142386 A, the main problem to be solved is that when the plastic granules are produced and packaged, the phe...
