Air purifier used in workshop with flying dust

Abstract

The invention discloses an air purifier used in a workshop with flying dust and belongs to the field of environmental protection equipment. A contaminant discharging pipe and a blowing pipe each communicate with an air supply pipe and are each arranged to be close to a filter screen. The connection positions, on the surface of the air supply pipe, of the contaminant discharging pipe and the blowing pipe are opposite. An air blower is arranged at the tail end of the blowing pipe. The contaminant discharging pipe is connected to the outside of the workshop. A beating mechanism used for beating the filter screen is arranged at the air outlet end of the air supply pipe. The beating mechanism comprises elastic pieces, a motor, a transmission shaft and a shifting piece set, wherein the transmission shaft rotate along with the motor coaxially, and the shifting piece set is located on the transmission shaft. The transmission shaft is arranged to be in parallel with the filter screen. The elastic pieces are vertically arranged at the bottom side, close to the air outlet end, of an exhaust fan. The shifting piece set is arranged at the positions, corresponding to the elastic pieces, on the transmission shaft. When the shifting piece set rotates along with the transmission shaft, by means of the shifting piece set, the elastic pieces are deformed intermittently toward the ends far away from the filter screen.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an air purifier used in a dusty workshop. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), products that effectively improve air cleanliness are mainly divided into household, commercial, industrial, and building. [0003] There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collecti...

AI Technical Summary

Problems solved by technology

The patent has high cost, high purification level, and low application value. It integrates multiple purifications, and the life of each purification process is different. It is easy for some purification processes to fail, and the replacement is inflexible. There will be pollution components brought by purification in the air, causing secondary pollution to the air, and the air purification effect is poor
