Description
Technical field
The present invention relates to a kind of water purifier and a kind of cleaning method, specifically, relate to automatic clearing apparatus and the cleaning way of a kind of water purifier.
Background technology
Ultrafiltration membrane water purifier can effectively cross the polluters such as the colloid in drainage, rust, sandstone, blood worm, antibacterial, and after using a period of time, a large amount of polluters are trapped within outside ultrafilter membrane, can affect aquifer yield and the service life of film silk. And when cleaning ultrafilter membrane, it being generally adopted two ways, one is that chemistry dosing is cleaned, and one is physical cleaning. It is be immersed in chemical agent solution by film silk that chemistry dosing is cleaned, and the polluter on film silk surface reacts the decomposition that comes off with chemical agent, thus reaching the purpose cleaned. Chemical cleaning can have efficient recovery aquifer yield, but this cleaning process is complicated, consumes medicament, and ultrafilter membrane is also can produce impact by chemical agent service life. Physical cleaning generally has forward to rinse and back flush, only relies on flushing, and ultrafilter membrane product water performance recovery is poor, and the key factor of physical cleaning is mechanical strength, and intensity is low, and degree of cleaning is inadequate, and intensity is too high can destroy film silk. Therefore improvement physical cleaning mode, is the key improving physical cleaning effect.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides the auto-cleaning method of a kind of high-efficiency washing and a set of efficient automatic cleaning device.
The technical solution adopted for the present invention to solve the technical problems is:
A set of ultra-filtration water purifier automatic clearing apparatus, including ultrafilter membrane cylinder 2, wash bowl 9, there are water inlet 1, outlet 4, sewage draining exit 7 in ultrafiltration cylinder top, has ultrafilter membrane, ultrafilter membrane to include film silk and build 5 in ultrafiltration cylinder, film silk 6. Ultrafilter membrane is built and is connected by center water inlet pipe 3 between 5 and the water inlet 1 of ultrafiltration cylinder. Wash bowl 9 includes upper end outlet 8 and lower end water inlet 11, connecing threeway at outlet 8, one end is connected with ultrafilter membrane cylinder sewage draining exit 7, and one end taps into air valve C3, threeway is connect at water inlet 11, one end taps into water valve C1, and water intaking valve C1 connects water inlet manifold 10, the lower drain valve C2 of another termination, lower drain valve C2 connects threeway, the lower valve C5 of threeway one termination, the other end connects drain valve C4, and upper drain valve C4 is connected with ultrafilter membrane cylinder water inlet 1.
When normally using, intake valve C3, lower drain valve C2, upper drain valve C4 close, and water intaking valve C1 opens, water from water inlet pipe 10 through water intaking valve C1, entering wash bowl 9, enter ultrafilter membrane cylinder 2 again through outlet 8 and ultrafilter membrane cylinder sewage draining exit 7, it is outside that pending water arrives film silk 6, filtration and infiltration enters inside film silk, by outlet 4 produce water for.
When film silk 6 surface contamination, enter wash phase. water intaking valve C1, upper drain valve C4 closes, intake valve C3, lower drain valve C2 opens, water in wash bowl 9 is discharged, turn off intake valve C3, lower drain valve C2, open water intaking valve C1, upper drain valve C4, intake by water inlet pipe 10 through water intaking valve C1, enter wash bowl 9, gas in wash bowl 9, it is pressed through outlet 8 and ultrafilter membrane cylinder sewage draining exit 7 enters ultrafilter membrane cylinder 2, gas produces pressure due to compression, can pour in the form of bubbles in ultrafilter membrane cylinder 2, film silk surface is carried out mechanical disturbance by bubble and surface is cleaned, the polluter on film silk surface passes through upper drain valve C4 and lower valve C5 together along with air-water mixture after coming off and discharges, complete to clean.
Again producing intake valve C3, lower drain valve C2, upper drain valve C4 when water uses to close, water intaking valve C1 opens.
This technique is manually operable, it is possible to realize timing automatic cleaning by electromagnetic valve and automatic control system.
Compared with prior art, there is advantages that
1., without dosing, physics cleaning can reach the effect of Chemical cleaning.
2. utilizing mixing wastewater with air disturbance to clean, water is more saved in just flushing conventional relatively at present, and effect becomes apparent from.
3. simple structure, easy to operate.
Accompanying drawing explanation
Fig. 1 embodies the structural representation of automatic clearing apparatus.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
When normally using, intake valve C3, lower drain valve C2, upper drain valve C4 close, and water intaking valve C1 opens, water from water inlet pipe 10 through water intaking valve C1, entering wash bowl 9, enter ultrafilter membrane cylinder 2 again through outlet 8 and ultrafilter membrane cylinder sewage draining exit 7, it is outside that pending water arrives film silk 6, filtration and infiltration enters inside film silk, by outlet 4 produce water for.
When film silk 6 surface contamination, enter wash phase. water intaking valve C1, upper drain valve C4 closes, intake valve C3, lower drain valve C2 opens, water in wash bowl 9 is discharged, turn off intake valve C3, lower drain valve C2, open water intaking valve C1, upper drain valve C4, intake by water inlet pipe 10 through water intaking valve C1, enter wash bowl 9, gas in wash bowl 9, it is pressed through outlet 8 and ultrafilter membrane cylinder sewage draining exit 7 enters ultrafilter membrane cylinder 2, gas produces pressure due to compression, can pour in the form of bubbles in ultrafilter membrane cylinder 2, film silk surface is carried out mechanical disturbance by bubble and surface is cleaned, the polluter on film silk surface passes through upper drain valve C4 and lower valve C5 together along with air-water mixture after coming off and discharges, complete to clean.
Again producing intake valve C3, lower drain valve C2, upper drain valve C4 when water uses to close, water intaking valve C1 opens.
When adopting the film cylinder of this embodiment and inflator structure, institute's water consumption is only inflator volume, is about 5L water, can be washed down by film silk surface attachments, and if adopt routine just rinsing, discharge is about 1.5m3/ h, continuous flushing 3-5min, institute's water requirement is 75-125L. Therefore, the method can reduce water consumption in a large number.
This device valve all adopts electromagnetic valve to automatically control, and can set fixed time cleaning, it is not necessary to human users, save labour turnover.
This device only adds the inflator of same volume and 5 electromagnetic valves on ultrafilter membrane cylinder limit, takes up room little and equipment simple, and it is convenient to install.
The above is the ultimate principle of the present invention, principal character and advantages of the present invention.
