The utility model discloses a great pressure is applyed to the booster pump to need let booster pump water at the back introduce the secondary filter delivery port through closing the booster pump, opening backwashing solenoid valve when needing back flush level filtering ware and secondary filter, and then form the back flush, the utility model discloses a method convenient and fast has thoroughly avoided leading preliminary treatment filter blockage's problem, can wash the frequency through the setting of PLC control program according to the difference of quality of water simultaneously.
Description
Technical field
This utility model relates to water treatment system technical field, is specifically related to a kind of preposition pretreatment rinse-system of water purifier.
Background technology
Filter is indispensable a kind of device on pumped (conveying) medium pipeline, is typically mounted on the entrance point equipment of the miscellaneous equipments such as air relief valve, relief valve, Valve for keeping constant water level.After filter deployment has the filter screen of certain specification, filter element or filter cylinder, its impurity is blocked, when needs clean, it is necessary to taken out by dismountable filter cylinder, reload after process.
RO reverse osmosis membrane water purifier is the important common apparatus of solid particle, antibacterial, virus, heavy metal, pesticide residues etc. in a kind of effective removal water.The preprocessing filter element of current RO membrane reverse osmosis water purifier is all manually cleaned, and while cleaning bothersome effort, water purifier preprocessing filter element easily blocks, thus causing the water purifier cannot normal operation.
But the preposition pretreatment of water purifier of existing major part has number of drawbacks, for instance after 1. defecator uses a period of time, it is necessary to manually open after defecator taking-up drainage screen carries out manual cleaning and install back again in device, complex operation, and affect equipment water；2. in defecator, drainage screen is to adopt ordinary steel wire to make, and it is easy corrosion after using a period of time, causes filter failure, affects equipment water；3. drainage screen place hydraulic pressure is excessive, and flow velocity is fast, poor filtration effect；4. anti-filter plant structure is complicated, and cost is high, dismounting difficulty, and a damage parts then needs to change multiple part or whole equipment simultaneously, causes later period maintenance cost high.
Such as Chinese patent CN203678071U discloses backwash filter, , comprise housing (5), described housing side comprises flange (1), the pipeline of described Flange joint is internal at housing (5), described pipeline is stainless steel filtering net (3), namely the pipeline of Flange joint there is filter opening very much, described housing is provided with current deflecting valve (4), current deflecting valve (4) comprises the circular slab on vertical bar and vertical bar, described circular slab is positioned at stainless steel filtering net (3), pipeline is stretched out in described stainless steel filtering net (3) end, pipeline stretches out housing (5) outward, the described pipeline stretched out comprises blowoff valve.
The filter element that above-mentioned patent can not well solve to occur in water purifier pretreatment system easily blocks, it is possible to conveniently carry out filter element cleaning.
Utility model content
The purpose of this utility model is to provide a kind of preposition pretreatment rinse-system of water purifier.
For reaching above-mentioned purpose, this utility model be the technical scheme is that a kind of preposition pretreatment rinse-system of water purifier of offer, including the grade one filter being sequentially connected with, secondary filter, tertiary filter, level Four filter and RO film filter；
For tap water being accessed the three-way magnetic valve of grade one filter；
Being arranged between secondary filter and tertiary filter for increasing the booster pump of hydraulic pressure for tertiary filter, level Four filter and the water of tertiary filter water inlet introduces the backwash electromagnetic valve of secondary filter outlet, described backwash electromagnetic valve accesses PLC；The pure water outlet of RO film filter accesses pure water tank, and wastewater outlet connects waste pipe.
Preferably, RO film filter is provided with check-valves with the connection pipeline of pure water tank；Waste pipe is provided with check-valves.
Preferably, the boost range of booster pump is 0.3Mpa ~ 0.4Mpa.
Preferably, the backwashing sewage water outlet of three-way magnetic valve accesses soil pipe.
In sum, this utility model has the advantage that
This utility model applies bigger pressure by booster pump to reverse osmosis membrane, tertiary filter and level Four filter when normal water supply, and require over when needing backwash grade one filter and secondary filter and close booster pump, open backwash electromagnetic valve by the water introducing secondary filter outlet after booster pump, and then form backwash；Method of the present utility model is convenient and swift, the problem thoroughly avoiding the blocking of preposition preprocessing filter element, according to the difference of water quality, can arrange flushing frequency by PLC control program simultaneously.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
In an embodiment of the present utility model, as shown in Figure 1, provide a kind of preposition pretreatment rinse-system of water purifier, including the three-way magnetic valve 6 being sequentially connected with, grade one filter 1, secondary filter 2, tertiary filter 3, level Four filter 4 and RO film filter 5.Tap water can be introduced grade one filter by three-way magnetic valve 6 so that tap water forms pure water after five filters filter, for forward flow when this utility model is to prepare pure water, for reverse flow during to clean filter element；Outlet of the present utility model refers to the outlet of filter when forward flow.
Being provided with between secondary filter and tertiary filter for increasing the booster pump 7 of hydraulic pressure for tertiary filter, level Four filter and the water of tertiary filter water inlet introduces the backwash electromagnetic valve of secondary filter outlet, backwash electromagnetic valve 8 accesses PLC.When preparing pure water, booster pump is that system boost accelerates pure water preparation efficiency, preparation process maintains between pipeline before and after booster pump certain pressure, the boost range of booster pump is 0.3Mpa ~ 0.4Mpa, then the pressure between secondary filter and tertiary filter is maintained at 0.3Mpa ~ 0.4Mpa.Backwash electromagnetic valve is connected in parallel on the two ends of booster pump, the backwash closed electromagnetic valve when normal condition, and booster pump is opened water supply start and prepared pure water, and the pure water outlet of RO film filter accesses pure water tank 9, and wastewater outlet connects waste pipe.
When backwash, booster pump cuts out, and backwash electromagnetic valve is opened；After backwash electromagnetic valve is opened, owing to having bigger pressure reduction between secondary filter and tertiary filter so that secondary filter and grade one filter are also carried out backwash by current reverse flow.The backwashing sewage water outlet of three-way magnetic valve accesses soil pipe 12, and the sewage of the backwash being can discharge.
In an optimal enforcement example of the present utility model, the connection pipeline of RO film filter and pure water tank 9 is provided with check-valves 10；The connection pipeline of RO film filter and waste pipe is provided with check-valves 11.
Although detailed description of the invention of the present utility model being described in detail in conjunction with accompanying drawing, but should not be construed as the restriction of the protection domain to this patent.In the scope described by claims, various amendments that those skilled in the art can make without creative work and deformation still belong to the protection domain of this patent.
