Description

Technical Field

[0001] This utility model relates to the field of ultrafine pulverizer technology, specifically to a dust removal mechanism for an ultrafine pulverizer. Background Technology

[0002] Ultrafine pulverizers are devices that use air separation, heavy pressure grinding, and shearing to achieve ultrafine pulverization of dry materials. The pulverized material is carried out of the pulverizing chamber by a negative pressure airflow generated by a fan and enters the material collection system. After passing through a bag filter, the air is discharged. Therefore, when the ultrafine pulverizer is working, it is necessary to filter the discharged gas through a bag dust collector to prevent air dust pollution. However, existing bag dust collectors lack a mechanism to handle dust escaping from the outside of the bags, causing dust seeping from the outer surface of the bags to float in the air, which has a negative impact on the working environment of the workers.

[0013] Compared with the prior art, this utility model provides a dust removal mechanism for an ultrafine pulverizer, which has the following beneficial effects:

[0014] 1. The dust removal mechanism of this ultrafine pulverizer uses a partition plate, a second air inlet slot, an atomizing nozzle, a U-shaped pipe, and an exhaust fan in combination. The exhaust fan draws air to the right side of the dust collection box, and the U-shaped pipe draws air from the bottom of the filter bag. The pulverized material is sucked into the filter bag.
