Manufacturing method of waste plastic regeneration particles

Abstract

The invention relates to a manufacturing method of waste plastic regeneration particles. A washing agent is added to waste plastic washing water; sieve pores in a crush screen piece are in three rows; and a seat tool and a moving tool are mounted in the form of a straight line; and the manufacturing method has the advantages as follows: a little amount of powder materials generated in the waste plastic crushing procedure are singly granulated, the washing degree can be increased, the product color and appearance are improved, the grade is increased and sales revenue is increased; in addition, the screening uniformity can be improved, the extruding speed of a granulator is increased and power consumption is reduced; and thermal degradation in the granulating procedure is avoided, so that the product yield of raw materials is further increased.

Description

technical field [0001] The invention relates to a production method of waste plastic regenerated granules. Background technique [0002] The raw materials of the existing waste plastic regenerated granule production are not high in cleanliness, poor in color and low in price. And the raw material crushing uniformity is poor. In addition, after crushing, waste plastics used for recycling granulation must meet stricter size requirements. If the size is too large, it will cause the throat of the extruder to be blocked, or the melting will be too slow, which will reduce the extrusion volume, reduce the output, and increase the unit energy consumption; however, if the size is too small, it will cause the melting to be too fast, resulting in thermal degradation , to reduce the yield of raw materials; therefore, the size of the crushed semi-finished products must be consistent to ensure that they are melted at a constant speed in the extruder. Generally, the sieve of the crusher...

Problems solved by technology

If the size is too large, it will cause the throat of the extruder to be blocked, or the melting will be too slow, which will reduce the extrusion volume, reduce the output, and increase the unit energy consumption; however, if the size is too small, it will cause the melting to be too fast, resulting in thermal degradation , to reduce the yield of raw materials; therefore, the size of the crushed semi-finished products must be consistent to ensure that they are melted at a constant speed in the extruder

Generally, the sieve of the crusher is a fence-shaped sieve hole. Since the large-sized unqualified material can easily pass through the sieve hole, the size of the intermediate product after sieving is extremely uneven.

Affected by this, the power consumption in the granulation process is high and the yield is low
