A kind of full-automatic self-cleaning filter comprises the filter tank body that has entery and delivery port and sewage draining exit, and the filter tank body is built-in with and filters and the backwash cell arrangement;
Described filter element device is made of the tubular coarse strainer and the fie screen that are provided with in the entery and delivery port path, and it is indoor that wherein the tubular coarse strainer is built up in the place ahead that has water inlet, and it is indoor that the tubular fie screen is built up in the rear that has delivery port;
Described backwash cell arrangement comprise one be built up in have in the tank body sewage draining exit preceding blowdown chamber and pass to from the afterbody end cap before the blow-off pipe of blowdown chamber, be provided with the several expansion formula scanner that can all scan fie screen between blow-off pipe and tubular fie screen, the blowdown of each telescopic scanner is pressed close to the fie screen inwall with sucking mouth.
The sewage draining exit place of described blowdown chamber is provided with motor-driven sewage draining valve.
Described telescopic scanner mouthful is formed by being fixed on fixed cover on the tubular fie screen, the expansion bend that can slide along the fixed cover upper wall and being fixed on sucking of expansion bend upper port, and fixed cover is built-in with the spring that the fie screen wall is close in mouthful maintenance of sucking that can make the expansion bend upper port.
The utility model has the advantages that:
1, the afterbody axis hole of blow-off pipe wears and is fixed on the axle that posterior end covers, and makes filtration device structure compacter.
2, the blowdown chamber is arranged on filter interior, can appearance and size shorten greatly under the situation that does not influence the filter process ability.
3, the contract design of formula scanner can be convenient to suck and mouthful be tried one's best filter screen, makes backwash effect more thorough.
Description of drawings
Fig. 1 is the full-automatic self-cleaning filter structural representation of the utility model (main cutaway view)
Fig. 1 a is the telescopic scanner enlarged drawing of full-automatic self-cleaning filter
Fig. 2 is the full-automatic self-cleaning filter vertical view of the utility model
Below in conjunction with specific embodiment and accompanying drawing the utility model is described further
The specific embodiment
As Fig. 1, Fig. 1 a and shown in Figure 2, the full-automatic self-cleaning filter of the utility model is one to have the filter tank body of entery and delivery port 1,15 and sewage draining exit, and the filter tank body is built-in with and filters and the backwash cell arrangement.
Described filter element device is stainless steel wire coarse strainer 2 and a fie screen 8 fixing in the filter tank body, this tubular coarse strainer 2 and fie screen 8 are located at respectively in the path between entery and delivery port, it is indoor that wherein the tubular coarse strainer is built up in the place ahead that has water inlet 1, and it is indoor that the tubular fie screen is built up in the rear that has delivery port 15.
Described backwash cell arrangement comprise one be built up in have in the tank body sewage draining exit preceding blowdown chamber 3 and pass to from the afterbody end cap before the blow-off pipe 16 of blowdown chamber, for shorten the monnolithic case size of this full-automatic self-cleaning filter as far as possible, the afterbody axis hole of blow-off pipe 16 wears on the axle 13 that is fixed on the rear portion end cap 14, the central tube front end has sewage draining exit 7, blowdown chamber and drive end bearing bracket 6 are made into integration to good, thereby form a global facility.Be provided with the several expansion formula scanner 9 that can all scan fie screen at blow-off pipe 16 and 8 of tubular fie screens, the blowdown of each telescopic scanner is pressed close to the inwall of fie screen 8 with sucking mouth 10; The concrete structure of this telescopic scanner constitutes can have a fixed cover 12 referring to shown in Fig. 1 a, and fixed cover 12 is fixed on the blow-off pipe 16; The main body expansion bend 9 of this telescopic scanner can slide along the upper wall of fixed cover 12; Design spring 11 in fixed cover 12, the mouth 10 of sucking at expansion bend 9 tops is pressed close to fie screen 8 inboards reliably under the squeezing action of spring 11, is convenient to suck more completely, clean.In the present embodiment, adopt the rotation of motor-driven blow-off pipe, the output shaft of this motor, reductor assembly 5 is connected with blow-off pipe by axle 17.
Described blowdown chamber is arranged on filter interior, can make appearance and size shorten greatly under the situation that does not influence the filter process ability, and its sewage draining exit place is provided with sewage draining valve, and this sewage draining valve is good by motor-driven, also can be provided with manually.
For in time observing the ruuning situation of filter, on the outside of coarse strainer 2 filtration tank body, the peep-hole of being convenient to observe coarse strainer 2 ruuning situations is arranged in the present embodiment.
The course of work of the present utility model is: when full-automatic self-cleaning filter operate as normal, the circulating water flow that needs to filter enters filter by water inlet 1, pass the inboard that enters fie screen 8 behind the bigger gap of coarse strainer 2, flow out from fie screen 8 less clearance, drain into the filtration that filter is finished recirculated water outward by delivery port 15.Along with being trapped in fie screen 8 inboard upward increasing of impurity, make filter water inlet 1 and delivery port 15 form pressure differentials.When pressure reduction reaches preset value, just start back cleaning system, at first open sewage draining valve 4, make blowoff valve 4, blow-off pipe 16, telescopic scanner 9 and suck mouthfuls 10 to communicate with atmosphere.Start drive motors 5 then, drive 12 rotations of blow-off pipe 16 fixed covers, in fie screen 8 with backwashing system under the effect of atmospheric pressure difference, cause relative filter screen inner face and the pressure differential between the outside, produce the powerful backwashing water of one suction and will suck the relative fie screen 8 lip-deep suspensions of mouthful 10 mouths and be drawn in the blowdown chamber 3 of drive end bearing bracket inboard, discharge by sewage draining valve 4 again.
