Description

PVC powder shale shaker unloading distribution device Technical Field The utility model relates to a powder vibrating screen, in particular to a blanking distribution device of a PVC powder vibrating screen. Background In the PVC powder processing industry, the vibrating screen is used as core equipment for realizing accurate screening and grading of materials, the running efficiency of the vibrating screen directly influences the product quality and the production efficiency, and currently, the blanking structure of the PVC powder vibrating screen at home and abroad mostly adopts a free blanking mode and a free distribution mode, so that the traditional design is widely applied to industrial production by virtue of the advantages of simple structure and low cost. However, with the improvement of the production refinement demand, the limitation of the traditional blanking mode is increasingly remarkable, when a large amount of PVC powder concentrates and blanking impacts the screen, the screen is required to bear the impact force of far-exceeding design load due to lack of a buffer structure, uneven screening stress is caused by uneven material distribution, and further local stress concentration is caused, so that fatigue and abrasion of the screen are accelerated, the screen at the blanking port is frequently damaged, the service life of equipment is shortened, the maintenance cost of the equipment is increased, and the practicability is poor. Disclosure of Invention The utility model mainly aims to provide a blanking distribution device of a PVC powder vibrating screen, which aims to overcome the defects in the prior art.
