Description
Technical field
The present invention relates to a kind of purifier, specifically, relate to a kind of forward filter negative pressure and cause ultrafiltration apparatus.
Background technology
Along with the in short supply of water resource and the aggravation of water pollutions, reutilization of the sewage technology has the advantage reducing water pollutions and using water wisely 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 Requirements uses motor pressurization, and filter process power 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 that a kind of design science, filter process Non-energy-consumption, structure are simple, the forward filter negative pressure of easy to clean causes ultrafiltration apparatus.
To achieve these goals, the technical solution adopted in the present invention is: a kind of forward filter negative pressure causes ultrafiltration apparatus, 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 comprises the membranous part water inlet end that can immerse pending former water and the delivery port be connected with the inlet seal of described negative pressure box.
Described on base, described negative pressure box top is provided with one-way exhaust valve.

Hinge structure of the present invention has outstanding substantive distinguishing features and significant progress, specifically, in the present invention, because pending former water is generally in former pond or raw water box, with ft connection, the membranous part water inlet end of hyperfiltration membrane assembly immerses pending former water, cause pressure outside milipore filter larger, the delivery port of hyperfiltration membrane assembly is communicated with the water inlet of negative pressure box, it is negative pressure of vacuum environment in negative pressure box, cause pressure inside the milipore filter of hyperfiltration membrane assembly very little, milipore filter both sides form pressure reduction, and then make the sewage in raw water box enter negative pressure box by described hyperfiltration membrane assembly, complete filter process, water in negative pressure box is extracted out by water pump, recover the vacuum negative pressure condition in negative pressure box, sewage in raw water box continues to be filtered in negative pressure box, thus constantly by sewage purification, because filter process 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 is roughly membrane portions water inlet, and delivery port unifies water outlet, and such structure spot can not enter in hyperfiltration membrane assembly, and it is easier to clean.
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, arrange raw water box, raw water box can uncoveredly be arranged, and also can add case lid, case lid arranges air-vent, its object is to keep the atmospheric pressure in raw water box consistent with the external world.Under needs saving utilizes the environment in space, negative pressure box can be located in raw water box, or raw water box and negative pressure box are close to setting, is even set to the structure of one case two Room, middle dividing plate arranges through hole and is communicated with two Room.Usually will pipeline between raw water box and negative pressure box, be used to connect.
Further, water pump is located in negative pressure box, structure assembly Du Genggao, the delivery port of water pump is communicated with the delivery port of negative pressure box, more compact structure, but needs to arrange water pump access hole, access hole place mounting sealing device, both ensure that normal service, also ensure that the negative regulation in negative pressure box.Water pump also can be arranged on outside negative pressure box, and the water inlet of water pump is connected with the delivery port of negative pressure box, and structure is simpler, installs and overhaul more convenient.
Further, negative pressure box delivery port road 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, bottom raw water box, sewage draining exit is set, clean for raw water box, meanwhile, outer water tube is set, is communicated with the delivery port of hyperfiltration membrane assembly, outer water tube is by supply equipment, as running water pipe or pump pressurizing unit supply water, carry out back flush to hyperfiltration membrane assembly, the sewage after flushing is discharged from sewage draining exit.The by-pass valve control that outer water tube is installed is one-way water inlet valve, can only intake, and to avoid in drainage process the interference of pressure in negative pressure box, ensures the closure of negative pressure box.
It has, and design science, filter process Non-energy-consumption, structure are simple, the advantage of easy to clean.
