Technical Field

The invention relates to the technical field of crushing equipment, in particular to a plastic material crushing device.

Background

The plastic foam has the characteristics of light weight, heat insulation, sound absorption, shock absorption, corrosion resistance and the like, is easy to form, has good water resistance, and is very low in price, so that the plastic foam is widely applied to the fields of packaging, heat preservation, water prevention, heat insulation, shock absorption and the like, and is one of the most widely applied plastics in the world at present.

The main component of the plastic foam is polystyrene, and the component is difficult to naturally degrade, so the plastic foam is generally required to be recycled, and the recycling of the plastic foam comprises the working procedures of cleaning, crushing, chemical reaction and the like, wherein a plurality of reagents are required to be added in the working procedure of the chemical reaction, so the characteristics of the plastic foam are changed, and the adopted current process finds that the crushed plastic material particles have irregular shapes and small specific surface area, so the reaction speed is slow, and the recycling efficiency is low.

Disclosure of Invention

The invention provides a plastic material crushing device, which aims to solve the problems that in the prior art, the reaction speed between plastic material particles and a reagent is low, and the recovery rate is low.

In order to achieve the purpose, the technical scheme of the invention is as follows:
