Description

Air filtering device for factory building Technical Field The application relates to the technical field of factory building air filtration, in particular to an air filtration device for a factory building. Background The air filter is an air filter device, is generally used for cleaning workshops, laboratories and clean rooms, or is used for dust prevention of electronic mechanical communication equipment and the like, the air filter is currently provided with a primary filter, a middle-efficiency filter, a high-efficiency filter and a sub-high-efficiency filter which are five types, the air filter comprises a shell, a filter screen, an air inlet, an air outlet and the like, and air entering the shell is filtered through the filter screen, so that the dust content of the air entering the workshops is reduced, and along with the continuous development of industrial technology, the structure and the function of the air filter are gradually improved to provide better workshop production environment. In the related art, as in the chinese patent of the utility model with publication number CN216367066U, a bag type air filter is disclosed, which comprises a filter vat and an air inlet barrel, wherein the outer walls of the filter vat and the air inlet barrel close to each other at one end are welded with connecting rings, the connecting rings are connected with each other through bolts, one side outer wall of the filter vat is provided with a reverse structure, the inner wall of the filter vat is welded with equidistantly distributed limiting blocks, the top outer wall of the limiting block is provided with a dust collecting assembly, the bottom center of the filter vat is connected with an exhaust pipe, one side outer wall of the air inlet barrel is connected with an air inlet pipe, and a filter screen is sleeved in the air inlet pipe.
