Polypropylene recycling method

Abstract

The invention discloses a polypropylene recycling method. A polypropylene recycling device comprises an operation platform, wherein two support columns are arranged on the upper end surface of the operation platform; a crushing box is arranged on the upper sides of the support columns; a crushing cavity is formed in the crushing box; a crushing mechanism is arranged in the crushing cavity and comprises a pushing block; a rotating cavity is formed in the pushing block; a crushing shaft is arranged in the rotating cavity; and a rotating blade is arranged on a shaft body of the crushing shaft. During operation, polypropylene is crushed with high efficiency under action of a cam and the rotating blade; the processing efficiency and the processing quality are improved; meanwhile, with cooperation of a tensioning mechanism and a sliding block, no fault is generated when the pushing block cannot move to the center; the device can automatically reset and operate again, so that the situation that the blockage is generated and causes halt of operation of the machine can be avoided; the device is capable of efficiently and automatically separating polypropylene from metal fragments and ensuring oneness of polypropylene fragments.

Description

technical field [0001] The invention relates to the field of polypropylene recovery, in particular to a polypropylene recovery method. Background technique [0002] At present, most of the polypropylene recovery devices at this stage use crushing when processing recycled polypropylene, and a large amount of polypropylene is crushed at the same time, which is very easy to cause blockage, resulting in machine failure, and a small amount of processing will affect the processing efficiency, and now It is inevitable that the polypropylene in the stage will be mixed with metal fragments during crushing. Most of the current polypropylene recycling devices only separate polypropylene in the initial state, and do not carry out after crushing, which may easily cause metals to be mixed in and affect the quality. Contents of the invention [0003] The object of the present invention is to provide a method for recycling polypropylene to solve the problems raised in the above-mentioned ...
