Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
It is the structural schematic diagram of the utility model air admission type self-cleaning filter as shown in Figs. 1-2；The utility model is a kind of
Air admission type self-cleaning filter, including body 1, the water inlet 2 that is arranged in 1 upper portion side wall of body and water outlet 3, the body
Air inlet pipe 14 is communicated on 1,1 bottom of the body is provided with filtrate storehouse 7, and the water outlet 3 is connected to 7 top of filtrate storehouse, institute
The water inlet pipe 5 for being provided in body 1 and being connected to water inlet 2 is stated, the water inlet pipe 5 is communicated with vertical tube 10, and the vertical tube 10 is arranged
The middle part in body 1,10 bottom of the vertical tube is provided with the water distributor 6 being connected to 7 lower part of filtrate storehouse, 10 inner sleeve of the vertical tube
Equipped with filtrate suction channel 9,9 lower section of the filtrate suction channel, which is extended to across water distributor 6 at 7 bottom of filtrate storehouse, is provided with arteries and veins
Formula elevator pump 11 is rushed, the air inlet pipe 14 is connected to pulsed elevator pump 11, and filtrate is provided at the top of the filtrate suction channel
Washer 12 is provided with the cleaning water inlet 4 being connected to filtrate washer 12 and ejected wash water sewage draining exit, filtrate on the body 1
The filtrate outlet 13 that 7 top of filtrate storehouse is connected to is provided on washer 12.
The present embodiment is based on countercurrent action, and pending sewage is through water inlet 2, water inlet pipe 5 and vertical tube 10, by being located at device
The water distributor 6 of body bottom enters in filtrate storehouse 7, and flow flows up through filtrate 8, and filtrate 8 slowly moves down；In the process,
Raw water is filtered, and the pollutant load in water reduces, and assembles at the top of body by filtered clear water, is flowed out through water outlet 3；
Pollutant load increases in filtrate simultaneously, and the pollutant load of lower layer's filtrate is higher than upper layer filtrate；It is now placed in filter
The pulsed elevator pump 11 in center is formed in air inlet pipe continuous gas entry, interval under the action of bubble, and lower layer's filtrate is passed through filtrate
Suction channel is promoted in the filtrate washer 12 at the top of body, so that pollutant is detached from filtrate 8 by action of turbulent flow simultaneously outer
Row, the filtrate after cleaning, which is returned using dead weight in filtrate storehouse 7, to be reused.
Further, the pulsed elevator pump includes the pump housing 15, and the atmosphere chamber of bottom opening is provided in the pump housing 15
16, it is sleeved on atmosphere chamber 16 and open-topped small air cavity 17, the small air cavity 17 is connected to by open top with atmosphere chamber 16,
The air inlet pipe 14 is connected to 15 top of the pump housing and is connected to atmosphere chamber 16 and small air cavity 17, and the filtrate suction channel 9 is simultaneously
It being sleeved in atmosphere chamber 17 and small air cavity 16,9 bottom of filtrate suction channel, which is extended in the setting of small air cavity 17, material sucking port,
The air admission hole 19 for being connected to small air cavity is provided on the tube wall that the filtrate suction channel 9 is located in small air cavity 17.
For the present embodiment by being equipped with small one and large one two air cavitys in the pump housing, two air cavitys are closed by open at one end one end
