Air filter

Abstract

The invention provides an air filter. The air filter comprises a base, a fan bracket, a fan, a dust removing structure, a dust brushing structure, a rotary closing cover, a motor, a water drenching pipe and a water pump, wherein the fan comprises an air draught tube and fan blades, and the air draught tube has an air inlet and an air outlet; the dust removing structure is arranged at the middle part of the air draught tube and comprises a filter screen and a dust collecting chamber, and the dust collecting chamber is lower than the air draught tube in position; the dust brushing structure is used for brushing away dust attached to one side, facing to the air inlet, of the filter screen and enabling the dust to fall into the dust collecting chamber; the water drenching pipe is mounted above the dust brushing structure and is used for flushing the dust brushed away from the filter screen inside the dust collecting chamber; the water pump is used for supplying water to the water drenching pipe. According to the air filter provided by the invention, the dust removing structure is arranged at the middle part of the air draught tube, and the dust brushing structure is arranged, so that when the filter screen needs dust removal, the dust brushing structure is started up to clean the filter screen, and the dust removal can be carried out without detaching the filter screen, is easy and is low in labor intensity; the dust cannot fly around, cannot be inhaled by workers and cannot affect the physical health of the workers.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to an air filter. Background technique [0002] In the prior art, the equipment used to separate dust from flue gas is called dust collector or dust removal equipment. Dust collectors are widely used in industry and daily life. In some occasions where there is a large amount of dust, In order to get clean air, people generally use air filters to separate dust from the air. [0003] The air filter includes a filter screen and a separation device. The dust removal process often uses the filter screen to filter the air first, and then transfers the retained dust to the separation device for separation. After a period of use, a large amount of dust will adhere to the filter to block the filter, affecting the filtering effect and dust removal efficiency. For the above situation, people generally use disassembly to clean up, that is, disassemble the entire air filter, and...
