The density of the water inlet ball check valve 101 is less than the density of water, can float on the surface；The water outlet ball check valve
102 density is more than the density of water, can sink to underwater.
The operation principle of the above-mentioned centrifugal backwashing sewage water lifter of the present invention is as follows：
Sewage containing miscellaneous dirt is by sewage water inlet pipe 9 by wastewater influent hole 82, left valve opening 83 and the right valve on bonnet 8
Hole 84 enters the left water inlet check valve chamber 103 and right water inlet check valve chamber 104 of combination check valve body 1, and by combination check valve body 1
On left inlet opening 108 and right inlet opening 109 separately flowed into by left connector 106 and right connector 107 positioned at combination check
In the recoil cask washing 2 of the left and right side of valve body 1, the sewage filtered by filter 3 is flowed into the sewage storage chamber 24 for the cask washing 2 that recoils,
Dirt under filtering is stored in the storage chamber 23 of recoil cask washing 2；The sewage of filtering is flow to by pipeline 5 by proof submersible sand discharging pump 4
Water tank or pond；When the water level of water tank or pond reach setting the upper limit when, can start wherein one proof submersible sand discharging pump 4 (below with
Illustrated exemplified by proof submersible sand discharging pump 4 on the left of startup), by the proof submersible sand discharging pump 4 by sewage after the filtering in water tank or pond
It is pumped into through piping 5 in the sewage storage chamber 24 of recoil cask washing 2 in left side, and flows into the inner chamber of cylinder 31 of wherein filter 3, by
Filter opening 32 on cylinder 31 flows out and helical form high-velocity flow is formed under the guide effect of prerotation vane 33 to recoil cask washing to the left
The inwall of 2 sewage storage chamber 24 is washed away, and makes on the inwall of sewage storage chamber 24 and the dirt of interior intracavitary is washed, by group
The left apopore 110 for closing check valve body 1 is discharged in the water outlet check valve chamber 105 of combination check valve body 1, and then by sewage outlet pipe
10 discharges；Because the density for ball check valve 101 of intaking is less than the density of water, it can float on the surface, the water outlet ball check valve
102 density is more than the density of water, can sink to underwater；Therefore, in forward direction water inlet, water inlet ball check valve 101 can be by water
Stream is washed open and flowed into the left water inlet check valve chamber 103 or right water inlet check valve chamber 104 of combination check valve body 1, and is now placed in
Water outlet ball check valve 102 at left apopore 110 or right apopore 111 sinks to blocks water into water outlet check valve chamber 105 under water
It is interior；And in back flush, the water outlet ball check valve 102 at left apopore 110 or right apopore 111 can be rushed to open and enter
Enter in water outlet check valve chamber 105, and the water inlet ball check valve 101 at left inlet opening 108 or right inlet opening 109 can float it is stifled
The firmly left valve opening 83 or right valve opening 84 on bonnet 8, to prevent sewage from flowing back in wastewater influent pipeline 9；When pipeline is carried out all the way
During backwash, another road can carry out positive sewage water filtration processing simultaneously.
It is visible in summary：Centrifugal backwashing sewage water lifter of the present invention, compact conformation is simple, without elbow three
The complicated pipeline structures such as logical reducing, non-return system is also simple in construction, except four ball check valves, without others movable part
Part, can be obviously reduced the possibility of pipeline blockage, also, occupation of land is small, can be installed and used in the space of very little, manufacturing cost
Low, operational reliability is good, has water tank cistern free to can be used, and backwash and combination check valve body assembly are located at sewage topmost,
Maintenance is convenient；Especially, the inner chamber of recoil cask washing is divided into dirt storage chamber and sewage storage chamber by filter, is constituting filtering
(prerotation vane is projected the multiple biasing certain angles of the longitudinally disposed multiple rows of filter bores of the week side of boss and interval setting of the cylinder of device with it
The angle theta in face be acute angle) prerotation vane so that the sewage of backwash by filter filter opening discharge and in prerotation vane guide effect
Lower formation helical form high-velocity flow, under spiral and centrifugal double-action, backwash current can wash away the internal chamber wall of recoil cask washing, cause
The dirt for making the precipitation on backwash barrel cavity wall be stained with knot can be discharged by effectively washing away, and it is miscellaneous to be not only prevented effectively from dirt
Thing precipitation blocks the possibility of filter, and can automatically remove and be stained with knot dirt on filter.Therefore, the present invention is relative to existing
Technology, not only with essential distinction, and with conspicuousness progress and application value.
It is last it is necessarily pointed out that：It the foregoing is only the present invention preferably embodiment, but the present invention
Protection domain be not limited thereto, any one skilled in the art the invention discloses technical scope in,
The change or replacement that can be readily occurred in, should all be included within the scope of the present invention.Therefore, protection scope of the present invention should
It should be defined by scope of the claims.
