Abstract
The utility model relates to a pressurizing self-flush ultra filtering drinking water device, which enables an ultra filtering membrane not to be blocked. A pressurizing back-flushing cleaning device is connected outside an ultra filtering drinking water device, and the inner part of the pressurizing back-flushing cleaning device is provided with a spring and a water storage telescopic cap. Thus the ultra filtering membrane can be often cleaned continuously and frequently and is kept clean and unblocked.
Description
Affiliated technical field:
The utility model has solved ultrafiltration water device filter membrane blockage problem, prevents the drinking water secondary pollution, and makes ultrafiltration water device drinking water delivery port flow keep stable, has improved the service efficiency of ultrafiltration water device, has prolonged the service life of ultrafiltration water device.
Background technology:
The ultrafiltration water device that existing market is supplied is made up of a branch of pipe, this pipe claims ultrafiltration pipe or claim ultrafiltration (Fig. 2 mark 7), and Fabric has expired diameter less than 0.01 micron micropore on the tube wall of ultrafiltration pipe, is called filter opening; In water treatment procedure, when containing suspended particulates, bacterium, iron rust, machine oil, colloid, the former water of microorganism etc. flows in the pipe of ultrafiltration pipe, and along tube wall when pipe is outer mobile, suspended particulates in the common water, bacterium, iron rust, machine oil, colloid, microorganisms etc. are intercepted in the pipe of ultrafiltration pipe or in the tube wall, through the drinking water after filtering, indexs such as microorganism in its water and turbidity all reach and surpass the standard of direct drinking water, and the various fine particles that are blocked are at the inner surface of ultrafiltration pipe, along water (flow) direction, inner surface by the ultrafiltration pipe gathers gradually to the outer surface of ultrafiltration pipe, even with most filter opening obstruction, the water treatment amount is reduced gradually, and cause secondary pollution easily, cause ultrafiltration water device drinking water delivery port flow to reduce, the drinking water secondary pollution, the service efficiency of ultrafiltration water device and life-span reduce greatly like this.
Summary of the invention:
Reduce and the drinking water secondary pollution problem in order to overcome the drinking water delivery port flow that exists in the use of ultrafiltration water device, the utility model provides a kind of drinking water delivery port flow to keep stablizing, not having the ultrafiltration water device product of secondary pollution, service efficiency height, long service life.
The technical scheme that its technical problem that solves the utility model adopts is: outside ultrafiltration water device (Fig. 1 mark 2), connect a pressurization recoil washer (hereinafter to be referred as washer Fig. 1 mark 5), enter washer through the drinking water after the processing of ultrafiltration water device by communicating pipe (Fig. 1 mark 4), a flexible cap (Fig. 3 mark 12) of a retractable water storage and a spring (Fig. 3 mark 10) are installed in this washer, the glassware for drinking water that recoil is cleaned has certain pressure, when the drinking water with certain pressure enters ultrafilter, drinking water is by flow in the export-oriented pipe of the pipe of ultrafiltration pipe (opposite with the water (flow) direction in the water treatment procedure), the various superfine particles that are gathered in the ultrafiltration pipe are taken out of by drinking water, this water is made washings and is used, make ultrafiltration be in control cleaning simultaneously, the cleaning that keeps the ultrafiltration pipe, solved the blockage problem of secondary pollution and ultrafiltration pipe, so just, make ultrafiltration water device drinking water delivery port water flow keep stable, drinking water is not subjected to the influence of secondary pollution, improve the service efficiency of ultrafiltration water device, prolonged the service life of ultrafiltration water device.
Therefore, the utility model keeps stablizing, not having the ultrafiltration water device of secondary pollution, service efficiency height, long service life for the user provides drinking water delivery port water flow.
Description of drawings:
Be described further below in conjunction with the drawings and specific embodiments:
Fig. 1 is a layout of equipment of the present utility model, among the figure 1: inlet valve, 2: ultrafiltration water device, 3: washings outlet valve, 4: communicating pipe, 5: pressurization recoil washer, 6: the drinking water outlet valve.
Fig. 2 is the vertical section structural map of ultrafiltration water device, among the figure 7: hyperfiltration membrane assembly, 8: shell.
Fig. 3 is the vertical section structural map of pressurization recoil washer, among the figure 9: fixed head, 10: spring, 11: portable plate, 12: the water storage cap that stretches, 13: shell.
Fig. 4 is the state of intake pressure when equaling spring pressure and adding the flexible cap bulbs of pressure of water storage.
State when Fig. 5 is the recoil cleaning, the state when promptly using washings.
State when Fig. 6 is to use drinking water.
The specific embodiment:
When opening inlet valve, when water enters the ultrafiltration water device, the drinking water of handling through the ultrafiltration water device enters washer by communicating pipe, because intake pressure is greater than the pressure in the washer, drinking water constantly enters in the flexible cap of the interior water storage of washer, constantly increases with rate of water added, the flexible cap of water storage constantly expands, make in the washer spring by compression, when intake pressure equals spring pressure and adds the flexible cap bulbs of pressure of water storage till, as shown in Figure 4.
The ultrafiltration pipe obtains cleaning when following situation:
A: when opening the washings outlet valve, because the drinking water pressure in the washer is greater than the pressure at washings outlet valve place, drinking water just passes through in the washer and enters communicating pipe in the ultrafiltration water device, and is flowed out by washings outlet valve place.When drinking water enters the ultrafiltration water device in washer, drinking water in the washer is flowed to inner surface by the outer surface of ultrafiltration pipe, the superfine particle that is intercepted in the ultrafiltration pipe is taken out of by drinking water, make ultrafiltration be in control cleaning, the washings outlet valve of drinking water below the ultrafiltration water device of carrying the superfine particle secretly flows out, make slurry, as shown in Figure 5.Owing in life, need to use washings constantly, ultrafiltration in the ultrafiltration water device is in control constant cleaning, solved secondary pollution and ultrafiltration pipe plug plug problem, made ultrafiltration water device drinking water outlet discharge keep stablizing, do not have secondary pollution, improved service efficiency, prolonged service life of ultrafiltration water device.
B: usually, inlet valve above the ultrafiltration water device is often opened, and washings outlet valve and drinking water outlet valve are normal closing, frequent earthwave moves in one day because tap water is pressed in, make interior pressure of washer and the pressure in the ultrafiltration water device be in a kind of dynamic balance, because the fluctuation of pressure, water in ultrafiltration water device and the washer is also in convection current mutually continually, make the ultrafiltration in the ultrafiltration water device be in control frequent cleaning, equally also solved ultrafiltration pipe plug plug problem, made ultrafiltration water device drinking water outlet discharge keep stable, there is not secondary pollution, improved service efficiency, prolonged the service life of ultrafiltration water device.
This shows that the utility model makes the ultrafiltration in the ultrafiltration water device be in control constant frequent cleaning, has solved ultrafiltration pipe plug plug problem.
When opening the drinking water outlet valve, water enters in the washer after handling through the ultrafiltration water device continuously, and is discharged by the drinking water outlet valve, as shown in Figure 6.
