Preferably, in described filter, described water storage tank water inlet and water storage tank delivery port are respectively apart from the each 10cm of lower limb on water storage tank.
According to the filter for sewage disposal of the present utility model, from improving of filter in form, sand filtration is used more convenient.In filter, can comprise water storage tank and water pump, thereby realize the design of backwash filtering integral, can reduce floor space.
Brief description of the drawings
By the description to the utility model embodiment referring to accompanying drawing, above-mentioned and other objects of the present utility model, feature and advantage will be more clear, in the accompanying drawings:
Fig. 1 shows according to the structural representation of the filter for sewage disposal of an embodiment of the present utility model.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, the utility model is described in more detail.In each accompanying drawing, identical element adopts similar Reference numeral to represent.For the sake of clarity, the various piece in accompanying drawing is not drawn in proportion.In addition, also may not shown some known part.
Fig. 1 shows according to the structural representation of the filter 100 for sewage disposal of an embodiment of the present utility model.This filter 100 is a kind of backwash filtering integral filtration systems, mainly comprise filter tank body 11, exhaust outlet 18, water storage tank 12, filler 10, upper strata water-locator 20, lower floor's water-locator 16, water pump 17, Pressure gauge 9, enterprising valve 1, upper valve 3, under enter valve 7, lower valve 6, outlet valve 8, air bleeding valve 14, water storage tank water inlet 13, water storage tank floss hole 2, filtering tank water inlet 19, filtering tank delivery port 15 and filter tank drain 5.Filtering tank water inlet 19 is connected with upper strata water-locator 20, enterprising valve 1, upper valve 3 by pipeline, filtering tank delivery port 15 by pipeline and lower floor water-locator 16, under enter valve 7, under go out valve 6, filtering tank outlet valve 8 is connected, exhaust outlet 18 is connected with air bleeding valve 14 and filtering tank 10, water storage tank water inlet 13 is connected with filtering tank outlet valve 8, and communicate with water storage tank 12 inside, water storage tank delivery port 2 communicates with water storage tank 10 inside, water pump 17 with under enter valve 7 and be connected, Pressure gauge 9 with under enter valve 7, under go out valve 6, outlet valve 8, lower floor's water-locator 16 and be connected.At filter 100 of the present utility model, the lowest part of filler 10 is 20cm apart from lower floor's water-locator 16, and highest point is 20cm apart from upper strata water-locator 20, and levels water-locator 20,16 is respectively apart from filtering tank 11 top edges and lower limb 10cm and 20cm.Water storage tank water inlet is apart from tank body top edge 10cm, and delivery port is apart from lower limb 10cm.
The housing of filter 100 shown in Fig. 1 is made up of stainless steel.Filtering interior filler 10, upper strata water-locator 20, the lower floor's water-locator 16 of arranging of tank body 11.Water pump 17 is set in water storage tank 12.
Filter 100 workflows are as follows.
A. exhaust
Before filter 100 puts into operation at every turn, first to carry out exhaust.When exhaust, first open the enterprising valve 1 of filter and air bleeding valve 14, water flowed into from upper inlet, when gas exhaust piping water outlet final vacuum complete.
B. regulate
After exhaust, regulate flow of inlet water.Open again lower valve 6, close air bleeding valve 14 simultaneously, water is flowed out from lower row mouthful.
C. operation
Regulate after inflow, filter enters pre-duty, then closes lower valve 6, opens outlet valve 8, and filter can put into operation.
D. backwash
When filter 100 runs to certain time, in tank body, impurity trapped is many, and filter 100 needs backwash, when backwash, open air bleeding valve 14, upper valve 3, under enter valve 7, close enterprising valve 1, outlet valve 8, water flows out from upper outlet.Backwash flow general control filtrate is not rushed out and is as the criterion, 3 times of left and right while being generally operation.When backwash is close with the transparency of water outlet to water inlet, backwash finishes.When backwash finishes, backwash flow reduces gradually, is beneficial to filtrate by granular size delaminating deposition.
E. just wash
After backwash, close down valve 7, upper valve 3 and outlet valve 8, open enterprising valve 1, lower valve 6, filtrate starts just to wash.Positive wash amount flow during for operation, the time is generally 10～20 minutes, is just washing completely when as clear as crystal to water outlet, and equipment can continue to put into operation.
Above embodiment of the present utility model is described.But these embodiment are only used to the object of explanation, and are not intended to limit scope of the present utility model.Scope of the present utility model is limited by claims and equivalent thereof.Do not depart from scope of the present utility model, those skilled in the art can make multiple substituting and amendment, within these substitute and revise and all should drop on scope of the present utility model.
