Description

Water purification machine

Technical field

The utility model is related to water purifier field, more particularly to a kind of water purification machine.

Background technology

Reverse osmosis technology is a kind of isolation technics, by bringing pressure to bear on the solution contacted with pellicle, in side shape Into weak solution (water outlet), and higher solution (concentrated water) is formed in the side of pressurization.Separate after high concentration solution need and When discharge, to prevent concentration from persistently increasing, cause required osmotic pressure to increase, water outlet reduce, and blocking reverse osmosis membrane.

Water purification machine is a kind of device filtered using reverse osmosis technology, will according to the design objective of the counter-infiltration rate of recovery Ask, water purification machine generally existing concentrated water ratio is big on the market at present, 2-3 times for pure water flow of usual concentrated water, water resource waste is tight Weight.

There is the water purification machine using concentrate recirculation technology on the market, the concentrated water that reverse osmosis membrane is produced presses one by current-limiting apparatus Surely backflow ratio reenters the inlet pipeline re-using of reverse osmosis membrane, and for the poor area of source water quality, concentrate recirculation enters One step deteriorates feed water by reverse osmosis water quality, so as to cause water purification machine effluent quality not up to standard.

In addition the water purification machine that with good grounds on the market water quality situation is adjusted, such water purification machine are not provided with return line, Water quality simply by detection source water or water outlet so as to adjust the opening degree of discharge of wastewater valve, economize on water by adopting said method Water purification machine can cause to reduce by the flow rate of water flow of reverse osmosis membrane, so as to cause reverse osmosis membrane filter element easily to block, service life Short.

Utility model content

The utility model provides a kind of water purification machine, and to solve in prior art, concentrated water ratio is big, causes water resource waste Problem.

For solving the above problems, as one side of the present utility model, there is provided a kind of water purification machine, including being sequentially connected Source water water inlet pipe, filter and pure water outlet pipe, the concentrated water outlet of the filter is by concentrated water outlet pipe and discharge The entrance connection of current-limiting apparatus, the outlet of the discharge current-limiting apparatus pass sequentially through water saving regulating valve, check valve and the filtration The entrance connection of device, the entrance of the discharge current-limiting apparatus connect also by entrance of the current-limiting apparatus with the check valve that flow back Connect.

Preferably, the filter is reverse osmosis unit.

Preferably, the water purification machine also includes booster pump, and the source water water inlet pipe is by the booster pump and the filtration Device connects.

Preferably, the water saving regulating valve is hand-operated valve or motor-driven valve or pneumatic operated valve.

The utility model by the entrance side of a part of concentrate recirculation to filter, and can pass through flow back current-limiting apparatus and section Water regulating valve is controlled to the concentrated water flow for flowing back, and so as to be effectively reduced concentrated water drainage, has reached saving water resource Purpose.

Specific embodiment

Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right It is required that the multitude of different ways for limiting and covering is implemented.

Fig. 1 is refer to, the utility model provides a kind of water purification machine, including the source water water inlet pipe 1, filtration dress being sequentially connected 3 and pure water outlet pipe 4 is put, the concentrated water outlet of filter 3 is connected with the entrance of discharge current-limiting apparatus 6 by concentrated water outlet pipe 5, The outlet of discharge current-limiting apparatus 6 is passed sequentially through water saving regulating valve 8, check valve 7 and is connected with the entrance of filter 3, discharges current limliting The entrance of device 6 is connected with the entrance of check valve 7 also by backflow current-limiting apparatus 9.Preferably, filter 3 is filled for counter-infiltration Put.

During work, source water enters filter 3 by source water water inlet pipe 1, and filter 3 is carried by pure water outlet pipe 4 For pure water, while the waste water of the output of filter 3 is then discharged by concentrated water outlet pipe 5, and can be by being arranged on concentrated water The concentrated water flow of the discharge control discharge of current-limiting apparatus 6 on outlet pipe 5.Additionally, the utility model can be by a part of concentrate recirculation To the entrance side of filter, and the concentrated water flow for flowing back is controlled by flow back current-limiting apparatus and water saving regulating valve, from And concentrated water drainage is effectively reduced, reach the purpose of saving water resource.

Preferably, water purification machine also includes booster pump 2, and source water water inlet pipe 1 is connected with filter 3 by booster pump 2.

Preferably, water saving regulating valve 8 is hand-operated valve or motor-driven valve or pneumatic operated valve.

Preferably, water purification machine also includes that the scouring electromagnetic valve for being rinsed to filter, discharge current-limiting apparatus 6 collect Into in scouring electromagnetic valve.

Preferably, water purification machine also includes control device 10 and the water quality for being detected to source water quality or effluent quality Detection means, control device control the aperture of water saving regulating valve 8 according to the testing result of water quality detecting device.Certainly, water saving is adjusted The aperture of section valve 8 can also be adjusted manually.

For example, when source water or effluent quality is detected preferably, water saving regulating valve 8 can be completely closed, by the current limliting dress that flows back The concentrated water for putting 9 fully enters source water water inlet pipe 1.Poor when source water quality is detected, or effluent quality is below standard, then by adjusting Section section water regulating valve 8, is partly into source water water inlet pipe 1 by the concentrated water of the current-limiting apparatus 9 that flow back, and a part is adjusted through water saving Valve 8 is drained by concentrated water outlet pipe 5.Excessively poor when source water quality is detected, or effluent quality is below standard, fully opens water saving Regulating valve 8, is all drained by concentrated water outlet pipe 5 by the concentrated water of the current-limiting apparatus 9 that flow back.In addition, check valve 7 is used for when water saving When regulating valve 8 is opened to certain aperture or fully opens, prevent the source water in source water water inlet pipe 1 from water saving regulating valve 8 not Filter through filter 3 and directly drain.

It can be seen that, the utility model can be adjusted according to the water quality of source water or water outlet, choose whether to start water conservation mode, or Person is adjusted according to a certain percentage.So as to reach the water saving for adapting to actual conditions while ensureing that effluent quality is up to standard；Both can be with Save water purification machine water, it is also possible to ensure effluent quality.

Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this For the technical staff in field, the utility model can have various modifications and variations.All of the present utility model spirit and principle Within, any modification, equivalent substitution and improvements that is made etc. are should be included within protection domain of the present utility model.
