Description
Technical field
The present invention relates to a kind of purifier, specifically, relate to a kind of reverse filtration negative pressure and cause ultra-filtration equipment.
Background technology
Along with the in short supply of water resources and the aggravation of water pollutions, reutilization of the sewage technology has the advantage reducing water pollutions and water saving double effects, is more and more subject to people's attention.Wherein, ultrafiltration membrane technique is high because of its filtering accuracy, can effectively bacterium, impurity etc. in filtering water, and the water quality after filtration is better, deeply welcomes by industry.But ultrafiltration membrance filter needs to form certain pressure reduction in filter membrane both sides, general requirement uses motor pressurization, and filtration procedure current consumption is large, makes cost of water treatment high, limits the universal of reclaimed wastewater reuse.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, thus provide the reverse filtration negative pressure of simple, the convenient maintenance of a kind of design science, filtration procedure Non-energy-consumption, structure to cause ultra-filtration equipment.
To achieve these goals, the technical solution adopted in the present invention is: a kind of reverse filtration negative pressure causes ultra-filtration equipment, comprise hyperfiltration membrane assembly, the negative pressure box that inside can form vacuum environment and the water pump being communicated with described negative pressure box, described hyperfiltration membrane assembly comprise for introduction into process former water water-in and seal with described negative pressure box the membranous part water side be communicated with.
Described on base, described negative pressure box top is provided with one-way exhaust valve.
Described on base, the membranous part water side of described hyperfiltration membrane assembly is located in described negative pressure box.
Described on base, described water pump is located in described negative pressure box and the water outlet of described water pump is communicated with the water outlet of described negative pressure box.
Described on base, the wallboard of described negative pressure box is arranged water pump access hole, described water pump access hole arranges tightness system.
Described on base, the water-in of described water pump is communicated with the water outlet of described negative pressure box.
Described on base, the water outlet of described water pump connects reclaimed wastewater reuse equipment, and the feed-water valve of described reclaimed wastewater reuse equipment and the switch gearing of described water pump are arranged.
Described on base, described reclaimed wastewater reuse equipment comprises tank for excrement pan or mop pool faucet or washing machine faucet or reuse water water tank.
Described on base, it also comprises the raw water box holding pending former water, and the water-in of described hyperfiltration membrane assembly is communicated with the water outlet of described raw water box.
Hinge structure of the present invention has outstanding substantive distinguishing features and significant progress, specifically, in the present invention, hyperfiltration membrane assembly arranges unified water-in, waste water is purified from inside to outside by ultra-filtration membrane, because pending former water is generally in former pond or raw water box, with ft connection, the feed-water end of hyperfiltration membrane assembly both inside ultra-filtration membrane pressure larger, the membranous part water side sealing of hyperfiltration membrane assembly is communicated with the water-in of negative pressure box, it is negative pressure of vacuum environment in negative pressure box, cause pressure outside the ultra-filtration membrane of hyperfiltration membrane assembly very little, ultra-filtration membrane both sides form pressure reduction, and then make pending former water enter negative pressure box by described hyperfiltration membrane assembly, complete filtration procedure, water in negative pressure box is extracted out by water pump, recover the vacuum negative pressure condition in negative pressure box, former water continues to be filtered in negative pressure box, thus constantly by sewage purification, because filtration procedure does not need external force to pressurize, because this reducing energy consumption, ultrafiltration membrance filter is more easily popularized.
Meanwhile, the structure of this kind of hyperfiltration membrane assembly makes water-in unified, and pressure more easily produces, and hyperfiltration membrane assembly can, away from pending former water, avoid external devices to be corroded, and due to the installation of separate type, overhauls also more convenient.
Original state, negative pressure box through vacuum pumping, need form negative pressure of vacuum environment.
Further, offer one-way exhaust valve, conveniently form subnormal ambient at the top of negative pressure box, during concrete operations, fill water by negative pressure box, the one-way exhaust valve that air is offered by top is discharged, and then utilizes water pump that water is detached formation negative pressure, starts working.
Further, membranous part water side is located in negative pressure box, and the water purifying direct oozed out is connected in negative pressure box and accumulates, and space availability ratio is higher, and volume is less.
Further, water pump is arranged in negative pressure box, offers water pump access hole, and further reduced volume strengthens its integrated level, and water pump also can be external, convenient maintenance.
Further, the water outlet of water pump connects reclaimed wastewater reuse equipment, and the feed-water valve of reclaimed wastewater reuse equipment and the switch gearing of water pump, during to ensure that feed-water valve is closed, water pump stall, avoids booster.
Further, arrange raw water box, raw water box can uncoveredly be arranged, and also can add case lid, case lid arranges breather hole, its object is to keep the normal atmosphere in raw water box consistent with the external world.
It has the advantage of design science, filtration procedure Non-energy-consumption, simple, the convenient maintenance of structure.
