Problems solved by technology

[0002] In order to filter the air in the ventilation duct, a filter screen is usually installed in the duct, and the filter screen is provided with a filter mesh. After filtering for a long time, the filter mesh will be blocked by a large amount of particulate matter. After the blockage, it needs to be cleaned regularly However, because the filter screen is installed in the deep part of the pipeline, it is very inconvenient to clean and take out, the labor intensity is high, and the entire cleaning cycle time is long, so there are many deficiencies in the cleaning of the existing ventilation pipeline filter device

Abstract

The invention discloses an air filtering device which comprises a filtering device body installed in a ventilation pipeline. The filtering device body comprises a fixing ring and a filter screen arranged in the middle of the fixing ring, one or more meshes are formed in the middle of the filter screen, first through holes penetrate through the same side, facing the meshes, of the fixing ring, oneor more second through holes are formed in the filter screen facing the first through holes in a '-'-shaped manner, and drawing pipes transversely penetrate through the first through holes and the second through holes. The brand-new filtering device body is adopted, the cleaning of the whole filter screen can be conducted only by pulling the drawing pipes on one side, and thus the filter screen can be quickly dredged; in addition, when lots of accumulation is produced, air exhausting can be achieved only by introducing negative-pressure gas, blocking substances in the meshes are sucked away byutilizing negative pressure, and the purpose of quick removal is achieved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air filter device. Background technique [0002] In order to filter the air in the ventilation duct, a filter screen is usually installed in the duct, and the filter screen is provided with a filter mesh. After filtering for a long time, the filter mesh will be blocked by a large amount of particulate matter. After the blockage, it needs to be cleaned regularly Cleaning, and because the filter screen is installed in the deep part of the pipeline, it is very inconvenient to clean and take out, the labor intensity is high, and the whole cleaning cycle time is longer, so there are many deficiencies in the cleaning of the existing ventilation duct filter device. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air filter device, which is mainly used for air filtration of ventilation ducts. To clean the whole filter de...
