Description

A PBT waste recycling and processing device

Technical Field

Background Art

PBT is one of the toughest engineering thermoplastic materials. It is a semi-crystalline material with very good chemical stability, mechanical strength, electrical insulation properties and thermal stability. The recycling of many PBT wastes formed in industry and modern life is the main way to reduce pollution and increase utilization rate. PBT waste needs to use recycling and processing equipment during the recycling process.

The recycling and processing device consists of a crushing knife, a roller and a motor. The motor drives the roller to rotate, and the roller drives the crushing knife on it to cut and crush the PBT waste, making the volume of the PBT waste smaller, which is convenient for subsequent recycling and processing.

In the process of crushing PBT waste, the existing recycling and processing device will produce a large amount of dust gas containing plastic particles after the PBT waste is crushed. After being inhaled by the human body, it is harmful to health and is very environmentally unfriendly, resulting in a poor environment and affecting the health of operators. Therefore, a PBT waste recycling and processing device is proposed to address the above problems.
