Description
【Technical field】
The utility model is related to water-purifying filter cleaning technique field, and in particular to a kind of water purification filter for being aerated backwash
Device.
【Background technology】
The deposit filtered in water-purifying filter, is mainly stopped by filtrate by colloid agglutinating matter and is formed, due to length
Accumulation, the accumulation of time can block filtrate space, reduce the operating efficiency of filter, to ensure the working effect of filter,
Timing is needed to carry out backwash operation；The current backwash to filtrate uses air purge and washing, and the flocculation in filtrate is sunk with gas first
Product filter material carries out impact loosening, then using water under high pressure back flush, the material being rinsed is rinsed water and takes away, and enters
Backwashing system, is discharged into sludge-tank；Due to one by one using Single Medium to precipitating the impact of filter material in filtrate, loosening and punching
Wash, the backwash process time is extended, because filtrate is not cleaned in time or change of water quality fluctuation in practice, in filtrate space
Filtering precipitate structural strength rise, formed consolidation, be difficult once by filtrate using washing process after traditional first air purge
Backwash often needs the backwash operation being repeated a number of times to desired clean level, and the time is longer.
【Utility model content】
To solve problems of the prior art, the purpose of this utility model is that offer is a kind of and is aerated the net of backwash
Water filter, the filter can will rinse aqueous medium and form inhomogeneous fluid media (medium) by original uniform dielectric, make deposition
Thing and the deposit of consolidation disintegrate, and are then rinsed medium and bring backwashing system into and are discharged into sludge-tank, can greatly save backwash
Time.
The purpose of this utility model is achieved through the following technical solutions：
A kind of water-purifying filter for being aerated backwash, including filter body, the upper end of filter body is connected with backwash

Compared with prior art, the utility model has the advantages that：
Due to filtering in filtrate space caused by normal work is flocculated deposited material blocking or does not backwash for a long time
The consolidation of deposit, causes filter work efficiency drop, and effect of harnessing the river is not up to Expected Results, therefore the utility model exists
The air container of the entrained gas into backwash medium is connected on scouring media pipeline, can be situated between by air container in backwash
Pressure-air is added in matter, backwash medium is changed into the fluid that heterogeneity is rich in bubble by original, using inhomogeneous
Fluid is vibrated and impacted to the agglutinating matter in filtrate space, is reached that it disintegrates, and is rinsed medium and brings backwashing system into,
Sludge-tank is discharged into, the utility model changes former single homogeneous medium flushing operation repeatedly, is changed into the single using inhomogeneous medium
Backwash operation, in operation by the control to high-pressure air pressure, flow, realizes the anti-of scouring media inhomogeneities
Multiple change, it is simple in construction, it is simple to operate, improve the effect of backwash efficiency and backwash.
Further, the outlet of air container is provided with the control valve for adjusting gas flow, hence in so that passing through this
The filter of utility model can control the compressed gas in air container to stablize release as requested when in use, it is therefore prevented that put
The too fast mistake of gas and damage equipment suddenly.
Further, it is provided for detecting the air gauge of control valve exit air pressure, energy by the outlet of control valve
It is enough that the pressure for being mixed into gas in scouring media is constantly observed by air gauge so that the control of control valve is more accurate.
Further, control valve uses ball valve or magnetic valve, can be stablized by ball valve and flexibly adjust air pressure, pass through electricity
Magnet valve can adjust outlet pressure when deflating, additionally it is possible to the release of pulsating be carried out to gas as needed, to scouring media
With gas formation pulse, both caused scouring media and gas mixing evenly, bubble is smaller finer and closely woven, still must rinse Jie
The fluid-mixing of matter and gas can carry out pulsating vibration and impact to the agglutinating matter in filtrate space, easily cause flocculate
Matter is disintegrated so that the clean level of backwash is high.
Further, the volume of air container is 10-20m3So that air container has certain pressure buffer function,
So that the air pressure of release is more stablized, it is ensured that the steady operation of the utility model filter.
