Filtering device for air purification equipment

Abstract

The invention relates to the field of environmental protection, and particularly discloses a filtering device for air purification equipment. The filtering device comprises a shell, an air feeder, anair cylinder and an air outlet pipe, wherein the interior of the shell is sequentially divided into a first water cavity, an extrusion cleaning cavity, a second water cavity, a drying cavity and a fine filtering cavity from left to right through partition plates; and a filter screen is fixedly embedded in a ventilation opening; an extrusion piston mechanism ascending and descending in a vertical direction is arranged in the extrusion cleaning cavity, a plurality of spraying holes penetrating through the top of a piston body communicate with the top of the cavity, and a plurality of water inletholes downwards penetrating through the bottom of the piston body communicate with the bottom of the cavity. In the cleaning process of the filtering device, only an air cylinder needs to be started,and the internal extrusion piston mechanism is driven by the air cylinder to move, internal filtering water serves as cleaning water to wash away dust on the filter screen, reduce the dust on the filter screen, clean the filter screen and guarantee air passing performance.

Description

technical field

[0001] The invention relates to the field of environmental protection, in particular to a filter device for air purification equipment. Background technique

[0002] People have always thought that the most serious air pollution is outdoors, but in fact, the indoor environment of factories, offices, living rooms, restaurants, theaters, Internet clubs, dance halls and other buildings has a much greater impact on people's health than outdoors. About 80% of the time in a lifetime is spent indoors. Therefore, the quality of the indoor environment directly affects human health. From the reality, the indoor air quality is far worse than the outdoor atmospheric environment. Therefore, we need to use air The purification filter device is used to filter and purify the air in the room.

[0003] The existing filter device for air purification equipment has a simple structure, and only needs to filter the filter. After the filter is used for a long period of time, the f...
