air filter

Abstract

The invention provides an air filter device capable of effectively removing magnetic foreign objects, effectively cleaning filter screen components, and ensuring the filtering effect. The air filter device involved in the present invention is used to filter particulate matter in the air, and is characterized in that it has: a housing; at least two filter components; a cleaning component, wherein the filter component includes a multi-layer filter screen, at least one filter At least one layer of filter screen in the component is a magnetic filter screen, and the cleaning component includes: at least one cleaning plate unit installed in the housing, each cleaning plate unit is located between two adjacent filter components, and has: a rotating plate; and a first cleaning liquid distribution pipe; an air blowing plate unit; a control unit; and a cleaning liquid discharge unit, which is installed at the bottom of the shell body and discharges the cleaning liquid with particulate matter from the shell body.

Description

technical field [0001] The invention relates to an air filter device. Background technique [0002] In industrial production and life, the air is mixed with many impurity particles, which will not only pose a threat to the health of workers' respiratory system, but also affect the quality of products. [0003] Existing air filter devices or air purifiers generally filter impurities and dust in the air through filter screen components, and the material of the filter screen components is usually non-woven fabric, glass fiber and the like. The air purification equipment used in the production workshop will accumulate a large amount of dust and other particles on the filter screen components after a period of use, and must be replaced regularly. If the use environment is relatively poor, the replacement frequency of the filter screen components will be higher. [0004] At present, the commonly used method is to directly replace the new filter element when the air volume of the ...

Problems solved by technology

The air purification equipment used in the production workshop will accumulate a large amount of dust and other particles on the filter screen components after a period of use, which must be replaced regularly. If the use environment is relatively poor, the replacement frequency of the filter screen components will be higher

[0004] At present, the commonly used method is to directly replace the new filter element when the air volume of the filter is less than 70% of the rated air volume, and then discard the old filter element, which not only causes waste of resources, but also greatly increases the cost of use. , and the disassembly and installation work is time-consuming and laborious

[0005] In order to avoid waste of resources and reduce costs, the prior art also provides a method of using cleaning liquid to directly clean the filter screen components, but the filter components are prone to breakage and damage after absorbing water, or the mesh is blocked by the cleaning liquid film, not only Resulting in a decrease in the filtering effect and adversely affecting the life of the filter element

[0006] In addition, in industries such as battery materials, the content of impurities is strictly controlled within dozens of ppm, especially magnetic foreign matter, which is strictly controlled within dozens of ppb. Effective removal of magnetic foreign matter
