This backflushing filtering device still is equipped with the pressure differential indicator. The beneficial effects of the utility model are that: 1, increase the suction pump in filtration system, increase the impulsive force that backwashing water erodees the filter screen, the rinse thoroughly filter screen, 2, add Y type pipe -line filter at the drain, filter the impurity in the sewage, utilize the using water wisely again.
Description
Technical field
The utility model is related to sewage water filtration technical field, and in particular to a kind of back-flushing filtering device.
Background technology
Water filter is widely used in metallurgy, chemical industry, oil, papermaking, medicine, food, mining, electric power, city water field.
Such as industrial wastewater, the filtration of recirculated water, the regeneration of emulsion, waste oil filtration treatment, the continuous casting water system of metallurgy industry, blast furnace
Water system, hot rolling high-pressure water descaling system.When its operation principle is that filter works, water to be filtered is flowed into by water inlet,
Filter screen is flowed through, by exporting into the needed pipeline of access customer process cycles are carried out, the granule foreign in water is trapped within filter screen
Portion.So constantly circulation, the particle being retained down is more and more, and the rate of filtration is more and more slower, and the sewage of import still source
Source constantly enters, and filter opening can be less and less, and pressure differential is thus produced between import and export, now needs to clean filter screen, recovers
The rate of filtration.
The water filter method for self-cleaning for often using at present is washed using intelligent pressure/differential control, timing controlled automatic backflushing
Filter screen.When filter inlet outlet pressure differential reaches setting time up to setting value or timer, electric operated control box sends signal driving
Valve is rotated, while blowoff valve is opened.At this moment current are forced to enter filter cylinder outside with housing folder from the entrance sector hole of filtering net cylinder
Layer, reversely rinses the impurity sticked on mesh from filter screen outside, reaches the purpose of cleaning screen pack, imports and exports when filter and presses
After difference recovery is normally or timer setting time terminates, motor stalls, electric blowdown valve is closed.The problem that the method is present
Impulse force is not big enough when being current scour filter screen, it is difficult to wash away clean.Another problem is that the water of backwash is directly arranged from sewage draining exit
Go out, cause to waste.
Utility model content
The utility model is defect present in solution prior art, there is provided a kind of back-flushing filtering device, can be thorough
Cleaning filter screen, while recycling backwashing water.
For achieving the above object, the utility model is adopted the following technical scheme that：
A kind of back-flushing filtering device, including housing, and the filter screen being arranged in housing；Shell one end is provided with into water
Mouthful, the other end is provided with pure water inlet；Pure water inlet connects water purification outlet pipe；One end of filter screen is in water inlet and the inwall of housing
Connection；The other end of filter screen is provided with outlet of sewer；Outlet of sewer is connected by the first pipeline with the pump mouth of suction pump, suction pump
Discharge outlet connect with the water inlet of piping filter；The delivery port of piping filter is connected by second pipe with outlet pipe.
Further, the piping filter is Y-type pipe filter.
Further, the filter screen is stainless steel wedge shape filter screen.
Further, the back-flushing filtering device is additionally provided with differential manometer, the high and low pressure joint of differential manometer connect respectively into
The mouth of a river and pure water inlet.
The beneficial effects of the utility model are：1st, increase suction pump in filtration system, increase backwashing water and wash away filter screen
Impulse force, thoroughly cleaning filter screen；2nd, Y-type pipe filter is set up in sewage draining exit, filters out the impurity in sewage, then in addition profit
With using water wisely；3rd, sewage draining exit need not arrange blowoff valve, it is not required that arrange blowdown valve control, when filter screen needs to rinse,
Suction pump need to only be opened and be capable of achieving flushing process；4th, backwash need not stop, and time-consuming short.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Label in figure：1st, water inlet；2nd, filter screen；3rd, outlet of sewer；4th, pure water inlet；5th, water purification outlet pipe；6th, second pipe
Road；7th, the first pipeline；8th, suction pump；9th, Y-type pipe filter；10th, housing；11st, differential manometer.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
A kind of back-flushing filtering device as shown in Figure 1, including housing 10, and the stainless gad being arranged in housing 10
Shape filter screen 2；The one end of housing 10 is provided with water inlet 1, and the other end is provided with pure water inlet 4；The connection water purification of pure water inlet 4 outlet pipe 5；Filter
One end of net 2 is connected at water inlet 1 with the inwall of housing 10；The other end of filter screen 2 is provided with outlet of sewer 3；Outlet of sewer 3 leads to
Cross the first pipeline 7 to connect with the pump mouth of suction pump 8, the discharge outlet of suction pump 8 is connected with the water inlet of Y-type pipe filter 9；
The delivery port of Y-type pipe filter 9 is connected by second pipe 6 with water purification outlet pipe 5.Back-flushing filtering device is additionally provided with pressure reduction
Meter 11.The high and low pressure joint of differential manometer 11 connects respectively water inlet 1 and pure water inlet 4.
When using, water to be filtered is flowed into from water inlet 1, and through filter screen 2, impurities in water is retained by filter screen 2, after filtration
Water enters water purification outlet pipe 5 from pure water inlet 4.When the display pressure reduction of pressure difference indicator 11 is too high, operating personnel open suction pump
8.The water in interlayer between the outside of filter cylinder 2 and housing 11 is increased by the suction of suction pump 8, flow velocity, the impulse force to filter screen 2
Also greatly increase, rapidly can sweep away the impurity adhered on filter screen 2, and discharge from sewage draining exit 3.Sewage is filtered through Y-piece road
