Technical Field

The utility model relates to the field of dust collection equipment, in particular to high-efficiency dust collection equipment.

Background

The concrete admixture is prepared by mixing several different powder raw materials in a certain proportion by a closed stirrer, conveying the mixed powder raw materials to a storage bin for material preparation by a spiral lifting pump after mixing, and conveying the powder and fibers to a semi-automatic sub-packaging machine for sub-packaging by a conveying device. Packaging, namely filling the packaging into bags according to each metering unit, and conveying the bags to a packaging process through a conveying belt, wherein the packaging process comprises the following steps: extruding, vacuum, hot melting, sealing, filling into a moisture-proof inner bag, filling into a paper box, sealing the box, packaging, and warehousing.

The production process is completed by workers or mechanical equipment, while the powder is polymer fine particles and the fiber is ultra-fine body with the length of 12 mm. The two materials have small specific gravity and are tiny, so that the two materials can float in the air, and certain influence can be caused to the environment and staff in the production process. In order to reduce the inhalation amount of workers, the workers need to wear a mask when entering a production area, and the workers are filtered by the mask. However, the mask has limited filtering capability, and is difficult to block a large amount of powder and fiber raw materials floating in a production area, and the filtering effect is reduced or even disabled after the mask reaches the saturation of filtering. Therefore, there is a need for an apparatus that can quickly absorb powder and fiber materials in the production area, clean air, and reduce mask load.
