Plastic particle cooling and sorting device

Abstract

The invention discloses a plastic particle cooling and sorting device. The plastic particle cooling and sorting device comprises a base, a sorting structure arranged on the base and a hopper arrangedat the top of the sorting structure. A feeding pipe is arranged in the base. A feeding fan is fixed to the side wall of the base. The sorting structure comprises a sorting base. A sorting cavity is formed in the sorting base. A circular feeding cavity is formed in the side wall of the sorting base. A plurality of screening holes communicating with the circular feeding cavity are evenly formed in the side wall of the sorting cavity. A waste discharging channel is formed in the bottom wall of the sorting base. A rotary motor is fixed to the center of the top wall of the sorting cavity. A shaft lever is arranged at the center of the sorting cavity. Pushing plates are evenly arranged on the shaft lever. A heat-dissipation chimney is arranged at the top of the sorting structure. A spiral cooling pipe is arranged between the sorting cavity and the circular feeding cavity. The plastic particle cooling and sorting device is reasonable in structure, and sorting can be effectively achieved; andmeanwhile, the cooling efficiency can be effectively improved, the stability in use is good, the applicability is high, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of plastic particle production, and in particular relates to a cooling and sorting device for plastic particles. Background technique [0002] During the processing of modified plastics, the modified plastics are often made into granular structures through extrusion equipment and extrusion dies. In order to ensure the uniform diameter of the prepared plastic particles and improve the quality of the product , all the prepared plastic particles need to be screened and classified. The traditional technology mainly screens and separates the materials first, and then sends the materials to the next process, and most of the screening devices in the prior art pass through vibrating screens so that Plastic granules pass through the sieve, but because the temperature of the freshly prepared plastic granules is relatively high, it is necessary to set up a fan to cool the plastic granules. However, due to the light wei...

[0002] During the processing of modified plastics, the modified plastics are often made into granular structures through extrusion equipment and extrusion dies. In order to ensure the uniform diameter of the prepared plastic particles and improve the quality of the product , all the prepared plastic particles need to be screened and classified. The traditional technology mainly screens and separates the materials first, and then sends the materials to the next process, and most of the screening devices in the prior art pass through vibrating screens so that Plastic granules pass through the sieve, but because the temperature of the freshly prepared plastic granules is relatively high, it is necessary to set up a fan to cool the plastic granules. However, due to the light weight of the plastic granules, air cooling will seriously affect the operation of the sieve, so Applicability and usefulness are limited
