Air filter

Abstract

The invention discloses an air filter. The air filter comprises an air suction / exhaust device 1, a dust filter device 2, a filtering water tank 3, a water storage tank 5, a circulating water pump 6, a water supply pipe 7, and an air purification device 8, wherein the dust filter device comprises ribbon filter screens which are driven to rotate by a power device and are connected end to end to be form a ring shape, one end of the ring is sleeved on an upper roll shaft, and the other end of the ring is sleeved on a low roll shaft. By adopting the filter screens, an air flow path is shortened, the practical filtering area is expanded, and the air filter is conductive to the use in working shops with heavy dust, such as a painting room.

Description

technical field [0001] The invention relates to a filter for filtering dust or oil fume in the air, which belongs to the air filtering technology. Background technique [0002] Taking the paint room as an example, a large amount of dust and harmful gases will be produced during work. These harmful substances not only affect the health of the operators, but also cause damage to the processing of the products. Therefore, the paint room will use ventilation equipment and dust filtration equipment, such as a water curtain machine that combines filtration and ventilation functions. The design of the water curtain machine is usually to set a baffle in the middle of the cabinet, the water flows from the top to the surface of the baffle to form a water curtain, a filter tank is set under the baffle, and a gap, so that the air flows from the gap between the baffle and the filter water tank to the blower, and the dust in the air will be absorbed by the water and flow into the filter ...

AI Technical Summary

Problems solved by technology

However, this structure is not suitable for many occasions

[0004] Taking the kitchen as an example, a lot of oily fume is generated when cooking, and the oily fume is discharged outside through the range hood. Although this design solves the problem of indoor oily fume, it will cause serious pollution to the flue and the surrounding environment. Therefore, there are also some The kitchen is equipped with degreasing and electrostatic precipitating devices, but this configuration has hidden dangers of high voltage leakage and fire

[0005] Now there is a kind of air filtration and cooling equipment for factory buildings, which sucks and filters the outdoor air and blows it into the room after cooling down. The advantage is low energy consumption, but the disadvantage is that the filter screen is fixed, and the filter screen is easy to be blocked after a long time of use. , Difficult to clean and maintain
