Description
Technical field
The utility model relates to effluent filter equipment technical field, is specifically related to a kind of self-cleaning filter.
Background technology
Sewage, be often referred to by certain that pollute, from life and the waste water produced.Sewage mainly contains sanitary sewage, industrial wastewater and early-stage rainwater.The ill pathogen contaminant of major pollutants of sewage, oxygen consumption pollutant, plant nutrient, toxic pollutant, impurity etc.
Industrial wastewater is the waste water produced in industrial and mineral activity in production.Industrial wastewater can be divided into production waste and factory effluent.Production waste refer to formed in process of production and pollute by the raw material such as raw materials for production, semifinished or finished goods, also comprise thermal pollution (refer to produce in production process, the water of water temperature more than 60 DEG C); Factory effluent refers to and is formed in process of production, but do not participate in directly production technology, not pollute by the raw material such as raw materials for production, semifinished or finished goods or the water of the just rare rising of temperature.Production waste needs to carry out purified treatment; Factory effluent does not need purified treatment or only needs to do simple process, as cooling processing.The combined sewage of sanitary sewage and production waste is called municipal sewage.
Effluent treatment and filtering device is mainly disposed of sewage, and makes it recycle.The use occasion of effluent treatment and filtering device has the supply and drain water system of metallurgy industry---continuous casting and rolling water system, blast furnace water system, turbid, the clean circulating water circulatory system and water charging system; The steam turbine cooling water system of power plant's industry; Boiler wet method cooling water system; Large-scale air compressor machine, large oxygen-making machine, large-size air conditioning machine cooling water system; Steam turbine seawater, lake water, river single flow cold filtration system.Also be widely used in agricultural drop irrigation water system.
In the effluent filter of prior art, due to the design feature of existing effluent filter itself, along with the removing of impurity will take away a large amount of liquid in the process of filtering blowdown, cause the consumption at water source.Result in the inefficiency of the effluent filter of prior art, water-saving result is bad, can not meet environment-friendly water-saving requirement growing at present.In the course of the work, impurity, once be stuck in the mesh of screen pack, does not have other ways except changing filter screen.This makes existing effluent filter maintenance and repair all very difficult.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, a kind of compact conformation is provided, floor space is little, automatic backwash can be realized, have and can tackle fine particle efficiently, filtering accuracy is high, and pollutant holding capability is large, filtration time is long, bears the self-cleaning filter that pressure is large.
The utility model solves the technical scheme that its technical problem adopts:
Self-cleaning filter, is characterized in that: include shell body, coarse strainer, fie screen, dirt sucking tube, whirligig, hydraulic motor, hydraulic piston, blowoff valve, intelligent controller; Described shell body is cylinder-like structure, and the inside is followed successively by coarse strainer, fie screen, whirligig from outside to inside; Described whirligig is also tubular structure, and whirligig includes a cylindrical shell, and cylindrical shell is provided with several dirt sucking tubes and is communicated with cylindrical shell, one end of cylindrical shell is connected with hydraulic motor, is provided with hydraulic piston in cylindrical shell, and the push rod of piston extends shell body.
In such scheme, described coarse strainer and fie screen are cylindric stainless steel sintered meshwork, and coarse strainer wraps fie screen, and fie screen wraps whirligig.
In such scheme, the upper surface of described shell body, is also provided with blowoff valve.
In such scheme, the lower surface of described shell body, is also provided with water inlet and delivery port, and water inlet and delivery port flange design are bascule, can rotate arbitrarily and regulate screw direction.
Principle of the present utility model is: water is entered by water inlet, first filters the impurity of larger particles through coarse strainer, then arrives fie screen.In filter process, fie screen builds up foul, impurity in water, forms impurity screening layer, because impurity layer is deposited in the inner side of fie screen, therefore just defines a pressure reduction in the inside and outside both sides of fie screen.When this pressure reduction (△ P) reaches preset value, automatic cleaning process will be started, continue to flow around here: blowoff valve will be opened, by hydraulic piston release pressure, water be discharged; Pressure in hydraulic motor and dirt sucking tube significantly declines, and produces a soil pick-up process thus by suction nozzle and hydraulic motor outer end.When current are through hydraulic motor, drive dirt sucking tube carry out axially-movable and rotate, gradually sewage is discharged.Whole filter screen inner surface can clean up by the combination of axially-movable and rotary motion completely.Whole flushing process only needed for 10 seconds.(4) blowoff valve cuts out at the end of flushing, and the hydraulic pressure of increase can make hydraulic piston get back to its initial position, and filter starts to prepare next flushing cycle, and the water purification after filtration is flowed out by delivery port.
Technical advantage of the present utility model is:
1. adopt stainless steel sintered meshwork, intensity is large, and corrosion-resistant, precision is high, is up to 2 microns.
2. adopt the backwash of filter screen external high pressure to combine with inner self-priming blowdown, thoroughly, filter screen can use all the life in cleaning, without the need to changing.
3., by self retrieval and strain function, unstable variation water quality can be tackled, realize automatic backwash, backwash is not middle stopping pregnancy water simultaneously, and run continuously, backwash lasts short, the backwash water yield is only 0.001% ~ 0.002% of normal aquifer yield, water-saving, power saving, the saving energy.
4. compact conformation is reasonable, and floor space is little, and intake-outlet flange design is bascule, can rotate arbitrarily and regulate screw direction, installs mobile flexible.
5. few easy workout part, sewage draining exit is by hydraulic seal, and without the need to magnetic valve or other frangible seal part, no material consumption, operation and maintenance cost is low, and operational administrative is simple.
