Pressure in backwash filter greatly damages filter itself very much.
In the present invention, straight mouth pipe end is equipped with hairbrush.It is improved based on above, the hairbrush being equipped with can be to filter in backwash
Net is cleaned with water, so that scavenging effect is more preferably.
In the present invention, bending towards for curved mouth pipe is consistent with inverse/clockwise direction.It is improved based on above, when backwash, is equipped with
Curved mouth pipe is able to drive sewage suction device rotation, is comprehensively cleaned with water to filter, cleans more thorough.
In the present invention, sensor is equipped in fine filtering room, sensor connects motor drive mechanism and motor by control circuit.It is based on
Above to improve, when the impurity filtered in backwash filter reaches specific degrees, i.e., the pressure difference in filter reaches setting
When value, filtering just can carry out backwash process by force automatically, realize the automation of backwash filter, save manpower object
Power.
In the present invention, control valve is equipped on wastewater inlet, water purification outlet and sewage draining exit.It is improved, is equipped with based on above
Control valve can control the water flow that backwash filter is respectively imported and exported.
In conclusion cleaning efficiency is high when the present invention backwashes, cleaning more thoroughly, be can satisfy to sewage water filtration and automatic
Change the quality requirement of blowdown.

Water inlet is connected to straining chamber 4, and 1 upper end of shell is equipped with motor drive mechanism 9 and water purification outlet 10, and motor drive mechanism 9 connects flow control plate 2, only
Water out 10 is connected to fine filtering room 5, and 1 lower end of shell is equipped with sewage draining exit 11, and sewage draining exit 11 is connected to blowdown room 6；Wastewater inlet, water purification go out
Control valve is equipped on mouth 10 and sewage draining exit 11；Coarse strainer 12 is arranged in straining chamber 4, and fie screen 13 connects 12 one end of coarse strainer
And be arranged in fine filtering room 5, coarse strainer 12 and fie screen 13 are cylindrical shape and form backwash chamber 7 with 1 inner wall of shell；Soil pick-up
Device is set in fine filtering room 5, and sewage suction device includes sewage pipe 14, high-pressure air pipe 15, dirt sucking tube 16 and exhaust pipe 17；Sewage pipe
14 is closed at one end, other end sealing connection blowdown room 6；High-pressure air pipe 15 is set in sewage pipe 14,15 1 end seal of high-pressure air pipe
It closes, the other end is in communication with the outside through blowdown room 6 and shell 1；Dirt sucking tube 16 has inner cavity that is several and being connected to sewage pipe 14；Exhaust
Pipe 17 is identical with quantity as the diameter of dirt sucking tube 16, and exhaust pipe 17 runs through the tube wall of sewage pipe 14 and is connected to the interior of high-pressure air pipe 15
Chamber, exhaust pipe 17 include straight mouth pipe and curved mouth pipe, and the outlet nozzle of straight mouth pipe flings the inner wall setting of shell 1, and straight mouth pipe end is set
There is hairbrush, its vertical tube body of the outlet nozzle of curved mouth pipe is arranged and bends towards consistent with inverse/clockwise direction；Feeder includes motor
18, air pump 19 and air supply pipe 20；Motor 18 is connect with air pump 19, and 20 one end of air supply pipe connects air pump 19, and the other end connects high pressure
Tracheae 15.Sensor is equipped in fine filtering room 5, sensor connects motor drive mechanism 9 and motor 18 by control circuit.
When backwash filter work, sewage enters through wastewater inlet, filters the miscellaneous of larger particles by coarse strainer 12
Reach fie screen 13 after matter, under fie screen 13 filters granule foreign lesser in water；In continuous filter process, fie screen 13
Dirty, the impurity crossed in drainage gradually form impurity screening layer, so that fine filtering room 5 and backwash chamber 7 form pressure difference；Sensor
Pressure difference signal is received, after pressure difference reaches the definite value of setting, backwash filter just realizes automatic cleaning depolluting processes.
It when automatic backwash, supplies water constantly, motor drive mechanism 9 works with motor 18, and sewage draining exit 11 is opened, and high-pressure installation generates

Strainer is cleaned, meanwhile, curved mouth pipe drives sewage suction device unitary rotation using high-speed flow, so that DC tube is to filter
It is whole carry out it is comprehensively clear, and be set to the hairbrush of direct current pipe end also to fie screen 13 carry out deeper into clean with water, reach recoil
The purpose that washed filter cleans comprehensively, cleaning effect is more preferably；Due to axially rotating for sewage suction device, drive in fine filtering room 5
Water also axially rotates, and the lateral current entered from wastewater inlet meets with the water flow axially rotated, so that depositing contaminants clean
More comprehensively thoroughly；Since sewage draining exit 11 is opened, the pressure in fine filtering room 5 is greater than the outer pressure of sewage draining exit 11, the impurity under cleaning
Sewage pipe 14 is sucked by sewage discharge tube, blowdown room 6 is flowed to by sewage pipe 14, is most afterwards discharged to impurity sewage outside through sewage draining exit 11
Boundary；Structure integrally makes the contaminant removal effectiveness of backwash filter high, cleans more thorough.
After the completion of backwash, motor 18 stops working with motor drive mechanism 9, and sewage draining exit 11 is closed, and backwash filter continues
Sewage water filtration is carried out, next backwash process is waited.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme should all cover within the scope of the claims and the description of the invention.
