Specific embodiment:
In order that juror can be further understood that to the purpose of the present invention, feature and function, hereby lift and preferably implement
Example simultaneously coordinates schema detailed description as follows:
Shown in Fig. 1 ~ 4: the present invention is a kind of filter wash pond, main include V-shaped groove 4, drainage ditch 5, filtering layer 6, air bag valve 7 and
Back purge system；
V-shaped groove 4 is located at the edge of filter tank both sides, and drainage ditch 5 is located at middle, setting filter between drainage ditch 5 and V-shaped groove 4
Layer 6；It is with the junction of total inlet channel and relative with the center of drainage ditch 5 that air bag valve 7 is installed on filter grid 8, divides in air bag valve 7 both sides
Water inlet 10 She Zhi not finely tuned；Air bag valve 7 is installed on filter grid 8 and the junction of total inlet channel 9 the center phase with drainage ditch 5
Right；Air bag valve 7 is made up of valve seat, valve body, protection baffle plate three part, and valve body and valve seat become the form that drawer type combines, valve seat by
Two u-shaped rustless steels 21 form, and u-shaped rustless steel 21 both sides are connected to fixed plate 22；Valve body is by corrosion resistant plate 23, hemispherical
Offset plate 24 and stainless angle bar 25 form, and stainless angle bar 25 is installed in corrosion resistant plate 23 rear end, and hemispherical offset plate 24 is fixed on rustless steel
Insert together on plate 23 in u-shaped rustless steel 21, hemispherical offset plate 24 is provided with aerating hole 26；Protection baffle plate 27 is fixedly mounted on
On pool wall, corresponding with the position of hemispherical offset plate 24.The present invention due to being designed using drawer type, drawer type valve body interchangeability
By force, in maintenance, replacing silica gel it is allowed to operate under higher water level, without the water in emptying inlet channel, than original saving
Substantial amounts of water.
In work process, aerating gas inlet hole, protection baffle plate 27 is against filter grid 8 wall water inlet after being full of by hemispherical offset plate 24
Place, thus water inlet is closed；The counteracting force that hemispherical offset plate 24 is subject to is delivered to filter grid after u-shaped rustless steel 21 absorption
On 8 walls, clearing up the active force disperseing to be subject to thus improving service life, in order to strengthen fastness further, selecting in rustless steel
The middle part of plate 23 rear end and be additionally arranged at the bottom the further counteracting counterforce of stainless angle bar 25.Certainly, can take in implementation process
Disappear protection baffle plate 27, hemispherical offset plate 24 is directly against filter grid 8 water inlet, such design can be by hemispherical greatly offset plate 24
Surface abrasion lead to the lost of life, and using protection baffle plate 27 can play transitional function thus protecting hemispherical offset plate, institute
The maximum feature stating air bag valve is exactly that versatility is high, can select the air bag valve of different size according to different water inlets, successfully avoid
Civil engineering transformation, install, the cycle is long, the difficult problem such as infusion of financial resources amount is big.
Shown in Fig. 1 ~ 2, described back purge system includes ultrasonic water level gauge, total valve 1, gas rushes valve 3, water rushes valve
2；Gas rushes valve 3 and water rushes valve 2 and is respectively connected in total valve, main valve gate control total water outlet crest of weir.Gas rushes valve 3 and aerator
Connect, water is rushed valve 2 and connected with flush water pump.
Before filter back washing, action being inflated by air bag valve 7, propping up filter grid 8 wall thus closing by protecting baffle plate 27
Close filter grid water inlet, the fine setting water inlet 10 of air bag valve 7 both sides can carry out micro-control according to leaching requirement size.Ultrasonic water level gauge 11 is visited
After survey water level reaches setting value, air bag valve 7 and total valve 1 are closed, and carry out backwash draining, backwashing water is equal through filter 12 respectively
Even entrance filtering layer 6 bottom, filtrate rinsed further, flows to drainage ditch 5 side by V-shaped groove 4 side and forms surface sweep washing and
OK；Then open valve 3 and open aerator entrance gas stroke sequence simultaneously；Then open valve 2, open a flush water pump and enter
Air water mixes stroke sequence；It is then switched off aerator and valve 3, enter water stroke sequence；Last backwash terminates, and impurity is discharged, and enters
Defects liability period.
Fig. 3 ~ 4 are shown as preferred technical scheme: described hemispherical offset plate 24 passes through rustless steel clip and bolt is solid
Dingan County is contained on corrosion resistant plate 23 so that hemispherical glue 24 plate obtains enough holding powers.Described hemispherical offset plate 24 is selected
Silica gel material is made, and the distance between hemispherical offset plate 24 and filter grid 8 wall are 115mm, and silica gel belongs to environment-friendly materials, is conducive to water
Matter health and health, water resistance is good, and in water, tension force enough, through long period of experiments, no ftractures, gas leak phenomenon,
Meet production requirement；And silica gel plate is cheap, to cost-effective favourable, there is not delivery cycle, normally yet
Produce guaranteed, through many experiments and selecting, finally select silica gel as the manufacture material of hemispherical offset plate.
Nut bolt and corrosion resistant plate 23 connection fastened to each other of m6 specification are adopted on described u-shaped rustless steel 21；U-shaped is not
For the fixed plate 22 being fixed on filter grid 8 wall in welding in the middle of rust steel 21 both sides；The distance between fixed plate 22 and filter grid 8 wall
Equal with the distance between hemispherical offset plate 24 and filter grid 8 wall, thus ensureing that hemispherical offset plate 24 can obtain optimal use
Environment.
Certainly, only better embodiment of the present invention illustrated above, not limits the range of the present invention with this, therefore,
Every equivalent change is made on the principle of the invention should be included in protection scope of the present invention.
