Air filtering device

Abstract

The invention provides an air filtering device which can effectively remove magnetic foreign matters, effectively clean a filtering net component and guarantee the filtering effect. The air filtering device provided by the invention is used for filtering grains in air and is characterized by comprising a shell, at least two filtering components and a cleaning component, wherein each filtering component comprises multiple layers of filtering nets; at least one layer of filtering net in at least one filtering component is arranged as a magnetic filtering net; the cleaning component comprises at least one cleaning plate unit which is arranged in the shell; each cleaning plate unit is located between two adjacent filtering components; the air filtering device is equipped with a rotating plate, a plurality of air nozzles, a first cleaning liquid distribution pipe, an air blowing plate unit, a control unit and a cleaning liquid draining unit; the cleaning liquid draining unit is arranged at the bottom of the shell and is used for draining the cleaning liquid attached with the grains from the interior of the shell.

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
