Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Embodiment.
As shown in figure 1, the present embodiment includes integrated water-purifying device 1, trapped well 2, water inlet pipe 3 and siphoning installation, one
Body water-purifying device 1 is connected with water inlet pipe 3, integrated water-purifying device 1 provided with filtering area 12 and under filtering area 12
The clear water zone 13 of side.Siphoning installation includes the siphon down-comer 7 that one end is located in trapped well 2, positioned at the upper end of siphon down-comer 7 and
The siphon tedge 9 and siphon destructing tube 11 being set with siphon down-comer 7, siphon tedge 9 are connected with filtering area 12, siphon
Flue gas pipe 6 is additionally provided with tedge 9, the one end of flue gas pipe 6 is connected with siphon tedge, the other end is located at trapped well 2
It is interior.The one end of siphon destructing tube 11 is located in trapped well 2, and the other end is located in clear water zone 13.Siphon is additionally provided with siphon down-comer 7
Auxiliary tube 8, the opening of the upper end of auxiliary siphon tube 8 is opened in the upper end side of siphon down-comer 7, and the opening of the lower end of auxiliary siphon tube 8 is opened
In the lower end side of siphon down-comer 7.
In the present embodiment, siphoning installation is also included on forced back washing water inlet pipe 4, the one end of forced back washing water inlet pipe 4 and siphon
Riser 9 is connected, and the other end is connected with water inlet pipe 3.Forced back washing water inlet pipe 4 is provided with forced back washing inlet regulating valve 5.Using institute
If forced back washing water inlet pipe 4 water in water inlet pipe 3 is sent into siphon tedge 9, force to promote the water in siphon tedge 9
Position constantly rise, so as to realize siphon backwash.
Wherein, forced back washing water inlet pipe 4 is provided with power set 15, and power set 15 are fixed on outside forced back washing water inlet pipe
Side.Set power set 15 can increase the flow velocity of water inlet in the case of necessary, improve the efficiency of forced back washing.
In the present embodiment, water purifier forced back washing device also includes control device 14, and control device 14 enters with forced back washing
Water regulating valve 5 is connected.It is capable of the switch of remote control forced back washing inlet regulating valve 5 by control device 14, also can control strong
The folding degree of backwash inlet regulating valve 5 processed, increases or decreases the flow into water.
The operation principle of siphoning installation is：With the continuous progress filtered in filtering area 12, filter material surface starts accumulation
Grain is more than the suspension and solid particle of particle diameter of filter medium, at the same time, passed through by the water of U-tube pressure required for filtrate by
It is cumulative big, when this pressure is more than the pressure that the water between overflowing to filter material surface from elevated tank is formed, in elevated tank
Water will no longer pass through filtrate, now the water level on the top of filtering area 12 can be slowly increased in siphon pipe tedge 9, siphon rise
Water level constantly rises in pipe 9, when the mouth of pipe of water level to auxiliary siphon tube 8, and water is discharged from 8 mouthfuls of slow discharges of auxiliary siphon tube
Current can take away portion of air, the vacuum after a period of time in auxiliary siphon tube 8 can start increase, concurrently siphon
Exhaust tube takes the air in siphon down-comer 7 away, increases the vacuum in siphon down-comer 7, now in siphon down-comer 7
Liquid level constantly rise, air is all drained by flue gas pipe 6, finally, in siphon tedge 9 and siphon down-comer 7
The water surface is contacted, and forms serial siphon effect.With the progress of siphonage, the pressure drop on the filtrate top in filtering area 12,
In the case where the pressure of bottom clear water zone 13 is constant, the clear water in bottom clear water zone 13 initially enters filter material layer, and filtrate is carried out
Backwash.With the progress of backwash, the water level in clear water zone 13 constantly declines, when water level decreasing to the mouth of pipe of siphon destructing tube 11
When following, gas enters siphon destructing tube 11, causes vacuum breaking, backwash terminates, and filtering restarts.
The present invention operation principle be：Forced back washing inlet regulating valve 5 is opened, entering for integrated water-purifying device 1 is utilized
Hydraulic pressure in water pipe 3, is sent into forced back washing water inlet pipe 4 up to flowing into siphon tedge 9 from water inlet pipe 3 by water, forces to promote
Water level in siphon tedge 9 is constantly raised.When water level reaches auxiliary siphon tube mouthful 8, water is fallen from pipe, is taken out by siphon
Tracheae 6, takes away the air in siphon down-comer 7, when vacuum reaches certain value, forms siphon.Siphonage makes water from siphon
Drastically fallen in siphon down-comer 7 in tedge 9, and then make to be formed the water in high vacuum, clear water zone 13 in filter chamber under
And on pass through and rinse filtrate.When the water level decreasing in clear water zone 13 is to the siphon destructive mouth of pipe 11, vacuum drops suddenly, backwash
Terminate.
Compared with prior art, using siphon principle, form siphon by pressure makes the backwash of integral water purifier to the present apparatus
Step is realized controllable, it is not necessary to additionally increase equipment, it is only necessary to transformed on former water purifier, and installation operation is simple.Make for a long time
It can extend the water purifier equipment service life of itself with the present apparatus, mitigate the burden of follow-up water treatment facilities, while ensureing stream
Enter the safety of unit operation.
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art,
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacing, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc. should be included in this
Within the protection domain of invention.
