Energy-saving and environment-friendly plastic grinding equipment

Abstract

The invention discloses energy-saving and environment-friendly plastic grinding equipment in the field of grinding equipment. The energy-saving and environment-friendly plastic grinding equipment comprises a box and a cooling device. A rotating shaft and a crushing device are arranged at the top of the box. A feeding funnel is arranged at the top of the crushing device. The lower end of the crushing device penetrates through the top wall of the box. The lower end of the rotating shaft penetrates through the top wall of the box to be provided with a grinding roller. A lower grinding device is arranged in an inner cavity of the box and is located below the grinding roller. Screening devices are arranged in the inner cavity of the box, the number of the screening devices is three sets, the screening devices are located below the lower grinding device, and guide plates are arranged below the three sets of screening devices. A lifter is arranged on the left side wall of the box. By means ofthe energy-saving and environment-friendly plastic grinding equipment, the grinding time is reduced, the sizes of grinding particles are adjusted, the situation that particles are scorched and go badis avoided through device cooling, plastic particles in limited intervals are screened out, and the situation that screens are blocked by particle accumulation is avoided through screen vibration.

Description

technical field [0001] The invention relates to the field of grinding equipment, in particular to an energy-saving and environment-friendly plastic grinding equipment. Background technique [0002] In order to save resources, plastics will be recycled and reused, and waste plastics need to be crushed and ground before being put into production to make their particle size meet the requirements. However, waste plastic grinders have the disadvantages of slow grinding speed and large particle size difference. Existing plastics The grinding machine has the disadvantages of slow grinding speed, non-adjustable particle size and inconsistent particle size. Therefore, it is urgent to develop an energy-saving and environmentally friendly grinding equipment for plastic recycling with fast grinding speed and uniform particle size. [0003] For example, the Chinese patent application number is CN201720858468.3, an energy-saving and environment-friendly grinding equipment for plastic recy...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an energy-saving and environment-friendly plastic grinding equipment to solve the problem that the existing device proposed in the above background technology directly introduces plastic into the grinding cylinder, increases the grinding time without crushing treatment, and the size of the ground particles cannot be adjusted. There is no cooling device, the temperature is too high during the grinding process may cause the plastic powder particles to burn and deteriorate, and the plastic particles in the limited range cannot be screened out, and the lack of a vibration mechanism may cause the plastic particles to block the screen.
