A kind of plastic particle screening equipment

Abstract

The invention discloses a screening device for plastic particles. The structure includes a crushing chamber, a screening device, a working chamber and a bottom frame. The crushing chamber is arranged on the working chamber. The working chamber communicates with the crushing chamber. The bottom of the outer wall of the working chamber is provided with an underframe, and the underframe is mechanically welded to the outer wall of the working chamber. The beneficial effect of the present invention is that the particles in the screening chamber are sucked into the collection chamber by using the external negative pressure source. The current increases the magnetism of the positive magnetic block, and according to the principle of same-sex repulsion, the rod body is driven to rotate and the stuck particles are ejected, so that they can be pulverized for the second time, which solves the problem of filtering due to the large amount of plastic particles. The gradual increase of the particles that will be intercepted will block the mesh holes so that the particles that meet the specifications cannot pass through the mesh holes.

Description

technical field [0001] The invention relates to the field of equipment for producing plastic granules, in particular to a screening equipment for plastic granules. Background technique [0002] After the development of plastic products, they are widely used. Since plastics are difficult to be decomposed by tiny molecules, plastics must be recycled after use and processed and recycled here. The current plastic particle screening equipment has the following defects: [0003] After the plastic products are recycled, they are crushed and reprocessed. The crushed plastics will have some particles with different sizes. It is necessary to screen the crushed plastic particles and crush them again. The traditional screening method is to set up a filter The net intercepts the particles that do not meet the specifications. Due to the large amount of plastic particles, the particles that will be intercepted during the filtration process will gradually increase and the mesh will be block...

Problems solved by technology

[0003] After the plastic products are recycled, they are crushed and reprocessed. The crushed plastics will have some particles with different sizes. It is necessary to screen the crushed plastic particles and crush them again. The traditional screening method is to set up a filter The net intercepts the particles that do not meet the specifications. Due to the large amount of plastic particles, the particles that will be intercepted during the filtration process will gradually increase and the mesh will be blocked so that the particles that meet the specifications cannot pass through the mesh.
