Description

Just filtering backwashing ultrafiltration device

The utility model relates to a kind of device that can separate gas, liquid by filter method.

It is filter core that this device adopts milipore filter, milipore filter is a doughnut, its core is empty, tube wall is fine and close aperture uniformly, the milipore filter model is determined with the weight shutoff value, the scope of weight shutoff value is 0.5-300KDa, and its aperture average diameter is 10-140 dust (be 0.001-0.014 μ m, virion is greater than 0.03 μ m).Mixture (gas, liquid) can pass aperture less than the material of weight shutoff value under pressure, and remaining is trapped, thereby reaches the purpose of separation.Leave and take macromolecular substances and claim to concentrate, leave and take small-molecule substance and claim purification, purifying, classification, be collectively referred to as ultrafiltration.At present, a lot of industries need be separated gas, liquid, as water-making industry (occupying civil version, clique, type of production, open-air system water), pharmacy industry, wine manufacturing industry, the catering trades such as beverage, vinegar, electron trade, gas purification, classification industry or the like, existing milipore filter stops up with the back, and cleaning is an a great problem, when the drag flow formula of just washing is cleaned, time-consuming, effort, clean-up performance is poor, and the ultrafiltration quality is affected to a great extent.General commercially available type water purifier or separator all can not backwashes, and need add filter (preliminary treatment) just, filter the back ultrafiltration earlier, filter just has active carbon formula, honeycomb pillar, micro-filtration membrane, nonwoven, asbestos etc., needs the regular dismounting flushing, and service life is very short, some months, economize on maximum 1 year and change, residual at ordinary times water cavity (filter core chamber) becomes the pollution sources that grow of microorganisms such as bacterium, virus, does not only reach the purpose of purification, and purifying waste water has on the contrary become sewage.

At problem set forth above, the utility model provides a kind of backwashing ultrafiltration device of just filtering, and its purpose is to solve to clean and need not dismantles or filter just, only needs back flush can reach the purpose of cleaning, has prolonged service life, improves advantages such as filter effect.

The utility model is achieved through the following technical solutions:

The position relative with the filter core chamber is provided with a cavity in housing, and the doughnut end between two chambeies is separated by epoxy resin, and epoxy resin is with the doughnut clearance seal; The filter core chamber connects with inlet tube, outlet, and cavity connects with inlet tube, outlet.

Filter core chamber, cavity respectively are connected to a pipe, and each pipe is controlled the inlet tube outlet respectively by the interlock valve.

Can distinguish steam vent of addition in the upper end of filter core chamber, cavity.

This utility model important breakthrough part is to have backwash mode, need not filter, direct ultra-filtration, large particulate matter is discharged by putting the residual mouth of a river (putting the former mouth of a river), the particle that is blocked on the fenestra can be discharged through backwash, clean-up performance as before, purification settles at one go, the long-term water quality of using can not reduce, and significantly improve service life.The water that makes through this water purifier does not contain microorganisms such as suspension, colloid, organic matter, big molecule, bacterium, virus, only contains ion, and this water is capable of direct drinking, claims high-quality purify waste water (excellent water purification), ionized water.Just filtering the filter of backwash water purifier and commercially available type, water purifier relatively as subordinate list 4.

Accompanying drawing 1 is a double pipe structure schematic diagram of the present utility model;

Accompanying drawing 2 is a single tube structural representation of the present utility model;

Accompanying drawing 3 is that outlet of the present utility model is all at the structural representation of lower end;

Subordinate list 4 is for just filtering the comparison of the filter of backwash water purifier and commercially available type, water purifier.

The utility model is specifically described by embodiment below in conjunction with accompanying drawing:

The utility model is to be provided with two chambeies in housing, is respectively filter core chamber 5 and cavity 6, and the doughnut end between two chambeies is separated by epoxy resin 7, and epoxy resin 7 gets up the clearance seal of doughnut.Inlet tube 1,2 and

outlet

3,4 are linked together with filter core chamber 5 and cavity 6 respectively.It is as follows that working method and backwash flow to mode:

1, just filtering and flow at 1 o'clock, material (gaseous state, liquid state) enters filter core chamber 5 by inlet tube 1 under pressure, enters in the cavity 6 by the through hole in the middle of the milipore filter (doughnut), flows out from outlet 4.

2, backwash flows at 1 o'clock, cleans material and enters cavity 6 by inlet tube 2 under pressure, enters in the filter core chamber 5 by the through hole in the middle of the milipore filter, flows out from outlet 3.

3, just filtering and flow at 2 o'clock, the flow of matter direction flows to 1 with backwash.

4, backwash flows at 2 o'clock, and the flow of matter direction flows to 1 with just filtering.

Flow in the working method just filtering,

outlet

3,4 connects with inlet tube 1,2 or connects with the other inlet tube of just filtering backwashing ultrafiltration device 1,2, forms the working method of circulation, better effects if.

In filter core chamber 5, the upper end of cavity 6 can distinguish steam vent 8 of increment, when liquid when cavity bottom enters, air is discharged from steam vent 8 in the chamber.

In accompanying drawing 2, filter core chamber 5, cavity 6 respectively are connected to pipe K, a L, and each pipe is controlled inlet tube 1,2 and

outlet

3,4 respectively by interlock valve A, B, C, D, and valve A, D open or close simultaneously, and correspondingly valve B, C close simultaneously or open.The flow of matter mode is the same, does not just need steam vent 8 on the structure.In like manner, also can one two, three-way valve be set at any two mouths controls.

Only be the bottom of outlet 3 being guided to cavity in the accompanying drawing 3, working method is the same.

Increase between the import and export pipe in filter core chamber 5 and cavity 6 and be associated with sieve class socket 9, sieve class socket 9 is the sieve shape thing of corrosion-resistant class, mixture enters from inlet tube 1 or 2, big molecule and particle directly flow out from

outlet

3 or 4, simultaneously can the residual mouth 10 of the row of setting up in chamber wall bottom, after the course of work finishes the raffinate in the cavity is discharged.In addition, in cavity, can be associated with heating or refrigerating plant, so that drink.

Can make through above backwash that milipore filter obtains fast, make things convenient for, water-saving (gas) cleaning, the clean-up performance in doughnut and chamber significantly improves, and milipore filter significantly prolongs service life, and milipore filter improves 10-100 times service life.

The major technique feature that the utility model proposed is to have additional a cavity 6.Macromolecular substances is owing to can not remain on the 6 interior hollow fiber walls of filter core chamber by milipore filter.When using certain hour to clean, the water that cleans is gone into cavity 6 from inlet tube 2, entering the mesopore of doughnut, enter in the filter core chamber 5 by hollow fiber walls, macromolecular substances is washed down from hollow fiber walls, flow out by outlet 3, so just can need not dismantle or filter just, only need back flush can reach the purpose of cleaning.
