Primary screening and grading device for plastic particles

Abstract

The invention particularly relates to a primary screening and grading device for plastic particles. The primary screening and grading device comprises a screening plate and supporting rods, wherein the supporting rods are arranged under the screening plate; the screening plate is obliquely arranged and comprises a first screening area, a second screening area and a third screening area; a plurality of screen holes are formed in each of the first screening area, the second screening area and the third screening area; the first screening area is located at the higher end of the screening plate;the third screening area is located at the lower end of the screening plate; the second screening area is located between the first screening area and the third screening area; the diameter of the screening holes in the first screening area is smaller than the diameter of the screening holes in the second screening area; and the diameter of the screening holes in the second screening area is smaller than the diameter of the screening holes in the third screening area. The device has the advantages of being simple in overall structure, low in cost, capable of preliminarily realizing grading andscreening of the plastic particles and simple and convenient in operation.

Description

technical field [0001] The invention specifically relates to a primary screening and grading device for plastic particles. Background technique [0002] The recycling and resource development of waste plastics is derived from a deep understanding of the environment and resources. It is a way of life to reduce the pollution of waste plastics to the environment and reduce the waste of resources. Most of the plastic products seen in daily life are produced by injection molding machines or blow molding machines. In the production process of plastic products using injection molding machines and blow molding machines, a large amount of plastic pellets are required to be melted and reshaped into new products. [0003] Since the diameters of plastic particles required by different plastic products are different, it is necessary to classify and screen plastic particles. However, most of the existing screening devices can only screen plastics of one diameter, and the structure is com...
