Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of mixed stirring device, especially in a kind of plastic powder fast mixing and stirring device with dust removal function. BACKGROUND

[0002] Plastic modification is to add various additives in plastic powder. In order to make the additives evenly dispersed in the plastic powder, the plastic powder and the additives need to be put into the mixer before modification and granulation, and the material is mixed. The top cover of the mixer is provided with a cover, and when the mixer is used for a long time, the cover will be slightly deformed, and a gap will be formed between the cover and the top surface of the barrel of the mixer, causing the plastic powder to diffuse out of the barrel. In addition, when a woven bag is used to cover the discharge pipe of the barrel to receive the mixed powder, the powder powder will also diffuse out of the gap between the woven bag and the discharge pipe. The diffused plastic powder will fall on the equipment and the ground, affecting the workshop environment, and there is even a risk of explosion when too much plastic powder diffuses out. Therefore, how to design a plastic powder fast mixing and stirring device with dust removal function has become a technical problem to be solved. SUMMARY
