Description

Self-cleaning filter

Technical field: the utility model relates to a kind of filter, particularly a kind of filter that is used to filter oil smoke or gas dust.

Background technology: the existing filter that is used to filter oil smoke or gas dust, the overwhelming majority does not have the self-cleaning function, whenever needs artificial the cleaning after a while, effort very, as clean and untimelyly can influence filter effect; Though the minority filter has the self-cleaning function, all increased the slag removing mechanism of forming by motor and brush etc., the higher and damage back inconvenient maintenance of cost.

Summary of the invention: the purpose of this utility model is to provide a kind of not to be needed to increase slag removing mechanism and has self-cleaning function, cheap filter.

Can realize the purpose of this utility model by following technical proposals, a kind of self-cleaning filter, comprise air inlet, casing, the gas outlet, it is characterized in that: be equipped with 3-12 in the casing at interval evenly and the netted filtering sheet that forms an angle with the air inlet direction, the corresponding parallel one section shower that evenly has fine hole and be interconnected downwards that is equipped with directly over each netted filtering sheet, be provided with a water tank below the casing, casing connects with water tank is movable, bottom half is equipped with a water pipe to be received on the fine and closely woven filter course of tank top, one water pump is housed in the water tank, and the water pump efferent duct is connected with shower.

Smooth and easy for filtering gas is flowed, in the gas outlet of filter blower fan is housed.

Effect of the present utility model is: 1, the slag on the cleaning and filtering sheet automatically; 2, cheap, and for ease of maintenaince; 3, filtering gas is discharged smooth and easy.

Description of drawings: accompanying drawing is an internal anatomy of the present utility model.

The specific embodiment: referring to accompanying drawing, even and vertical with the air inlet direction netted sheet 4 of crossing in 4 intervals is housed in the casing 2, filter 5, filter 6, filter 7, filter 4, filter 5, filter 6, the corresponding parallel shower 8 that evenly has fine hole and be interconnected downwards that is equipped with directly over the filter 7, shower 9, shower 10, shower 11, shower 8, shower 9, shower 10, shower 11 is interconnected, be provided with a water tank 12 below the casing 2, casing 2 and 12 movable connections of water tank, casing 2 bottoms are equipped with a water pipe 14 and are received on the fine and closely woven filter course 15 at water tank 12 tops, one water pump 13 is housed, water pump efferent duct 16 and shower 8 in the water tank 12, shower 9, shower 10, shower 11 is connected.When filter is worked, water pump 13 enters shower 11 with the hydraulic pressure entry pump main 16 in the water tank 12, shower 10, shower 9, in the shower 8, shower 11, shower 10, shower 9, water in the shower 8 is by its aperture filter 7 of flowing through respectively, filter 6, filter 5, filter 4 flows into casing 2 bottoms, again through the flow through fine and closely woven layer 15 of crossing at water tank 12 tops of water pipe 14, flow at last in the water tank 2, form a water circulation system, oil smoke or the gas that contains dust enter in the casing 2 by air inlet 1, flow through filter 4 by water, filter 5, filter 6, during water curtain that filter 7 forms, gaseous state oil in the oil smoke is met water curtain cooling liquefy oil, fluid oil flows into casing 2 bottoms, dust in the gas is adsorbed by water curtain and pours casing 2 bottoms, thereby realize filtering purpose, because water is the washing and filtering sheet incessantly, filter is played automatic cleaning action, in the gas outlet 3 of filter blower fan is housed, it is smooth and easy that filtering gas is flowed.

Filter of the present utility model can be set to any among the 3-12, with air inlet direction angle can be any acute angle or right angle.
