Antistatic screening device for engineering plastic production

Abstract

The invention belongs to the technical field of plastic granulation equipment, and provides an antistatic screening device for engineering plastic production. The screening device comprises a main body, a first filtering assembly, an impurity output pipeline, a bag replacing device, a second filtering assembly, an impurity collecting disc, a good product output device and dust filtering bags. Themain body comprises a first convex block, a second convex block and dust collection fans. The first filtering assembly comprises a first material blocking plate and a first screening net, the upper plate surface of the first material blocking plate is an inclined surface, intersects with the plane where the first screening net is located, and forms a funnel shape with the first screening net. A plurality of groups of dust filtering bags are mounted on the bag replacing device in an annular array mode. The second filtering assembly comprises a second screening net, and the impurity collecting disc is arranged below the second screening net. By means of the screening device, the main problems that an existing screening device is prone to blockage during discharging, filtering and screening are incomplete and not environmentally friendly, and harm to the physical health of operators occurs are solved.

Description

technical field [0001] The invention belongs to the technical field of plastic screening equipment, in particular to an antistatic screening device for engineering plastic production. Background technique [0002] After the plastic particles are produced, it is necessary to filter the plastic particles of different sizes mixed in the plastic particles, as well as a small amount of impurities and iron filings. The feed hopper of the existing screening device has complicated functions, is easy to block and has high equipment cost, and the existing screening device lacks the functions of dust removal and iron removal. Once these dust and iron filings enter the production stage of plastic products with plastic particles, it will cause Plastic products are scrapped, and the machines that produce plastic products are seriously damaged. In addition, the existing screening device produces a large amount of dust during screening and filtering without collecting and processing, which...

Problems solved by technology

The feeding hopper of the existing screening device has complex functions, is easy to block and has high equipment cost, and the existing screening device lacks the functions of dust removal and iron removal. Once these dust and iron filings enter the production stage of plastic products with plastic particles, the Plastic products are scrapped, and the machines that produce plastic products are severely damaged

In addition, the existing screening device generates a large amount of dust during screening and filtering without collecting and processing, which seriously endangers the health of operators
