Plastic product sand removal device and method

Abstract

The invention discloses a plastic product sand removal device and method in the technical field of plastic product sand removal. The device comprises a box body, a rotating rod is inserted in an innercavity of a bearing, cleaning rods are evenly arranged on the left side and the right side of the rotating rod, a first filter net, a second filter net, a hopper and a water box are sequentially arranged in an inner cavity of the box body from top to bottom, cleaning liquid is sprayed out through a water outlet hole through a water pump, plastic product surfaces are washed, the cleaning rods rotate to drive bristles to brush the plastic product, the first filter net separates the cleaning liquid mixed up with gravel and the plastic product, the second filter net separates the cleaning liquidand the gravel, the second filter net shakes up and down, filtering and cleaning of the gravel are facilitated, the cleaning liquid mixed up with fine gravel and dust is precipitated in a precipitation chamber, a mesh-free filter layer filters fine gravel and dust mixed up in the cleaning liquid, through layer-by-layer filtering of the cleaning liquid, circular utilization of the cleaning liquid is achieved, and resource waste is reduced.

Description

technical field [0001] The invention relates to the technical field of sand removal for plastic products, in particular to a sand removal device and a sand removal method for plastic products. Background technique [0002] In the various links of recycling plastic products, the surface of plastic products adheres or wraps some sediment substances. In the process of crushing plastic products, on the one hand, the sediment and pebbles adhered to waste plastics It will seriously damage the cutter of the crusher, making the cutter blunt faster, thereby reducing the crushing efficiency. On the other hand, these materials such as sand, mud and small stones may also block the material channel of the equipment, resulting in poor operation of the equipment. Therefore, Generally, when recycling plastic products, it is necessary to remove the sand and clean the plastic products first, so as to reduce the impact of the sand on the surface on the cutter when it is broken. This method is...

[0002] In the various links of recycling plastic products, the surface of plastic products adheres or wraps some sediment substances. In the process of crushing plastic products, on the one hand, the sediment and small stones adhered to waste plastics It will seriously damage the cutter of the crusher, making the cutter blunt faster, thereby reducing the crushing efficiency. On the other hand, these materials such as sand, mud and small stones may also block the material channel of the equipment, resulting in poor operation of the equipment. Therefore, Generally, when recycling plastic products, it is necessary to remove the sand and clean the plastic products first, so as to reduce the impact of the sand on the surface on the tool when it is broken. This method is highly dependent on water, the waste of water resources is serious, and the sewage produced has a certain impact on the environment. Therefore, a sand removal device and a sand removal method for plastic products are needed
