Description
Technical field
The utility model relates to a kind of isolation technics, relates in particular to a kind of self-cleaning membrane filter filter core.
Background technology
Filtration is important in a liquid-solid separation method, for large flow, and large batch of liquid filtering, the filter that many employings can automatic backwash.The filter of automatic backwash mainly contains medium class filter at present, screen cloth class filter, and the fiber-like filter, film class filter etc., every kind of filter has its applicability.Film class filter has a wide range of applications in the Separation of Solid and Liquid field as main class filter a kind of capable of washing, and the membrane filter filtering accuracy is wide, and the film kind is many.The filter of common film class has many disk filters on the market, rotary drum filter etc., such filter generally all adopts high pressure water washing regeneration, but in order to satisfy the requirement of cleaning, monolithic filter is not with the pressure operation, film filling area is little in the system, and system takes up an area large, and the backwash water consumption is very large.The collection of filter cake is difficulty also.U.S. Aquatech company has developed a kind of film filter disc filter, the mode backwash of adopting vacuum to suck, improved greatly film filling area, but the pressure that vacuum is sucked is no more than 1 atmospheric pressure, is difficult to realize effective backwash for some relatively more sticking impurity.In addition, this filter can only be applicable to water body filtration, can not collect filter cake.Domestic also someone attempt with film cover on porous in be lining with the formation candle filter, but the non-constant of backwash effect is found in practice, can not fine collection filter cake.Based on present present situation, the inventor thinks that to develop a kind of filling area large, and efficiently backwash and the self-cleaning membrane filter of effectively collecting filter cake will have very large market prospects.
The utility model content
The purpose of this utility model is to provide a kind of self-cleaning membrane filter filter core for the prior art weak point.This filter element can filter the liquid that contains suspension, reduces the suspension in the filtrate, also can collect the suspension filter cake.
The utility model is by the following technical programs in to realize: a kind of self-cleaning membrane filter filter core, it is characterized in that, and it includes some filter core monomers, drain pipe; Described filter core monomer is comprised of film, inner support, stalk, inner support forms, is on the outer cylinder that the petal type structure is distributed on stalk by some hollow tube disjunctors that are column, the inner support upper base is connected with the stalk outer fringe seal, go to the bottom sealing, each hollow tube of inner support of inner support is communicated with at the bottom of the stalk pipe by the pipe base space, has some phases circumferential slit across a certain distance along its axis direction on the inner support petal type outer cylinder; Described film is made the filter cylinder shape, is covered on the inner support petal type outer cylinder, and film upper/lower terminal and inner support are tightly connected, and the stalk of described each inner support is sealedly connected on the drain pipe.
Be furnished with vertical groove on the described inner support petal type outer cylinder.
Good effect of the present utility model is: a kind of self-cleaning membrane filter filter core that the utility model proposes, have following advantage: film is being close under the effect of filtration pressure difference on the petal type inner support cylinder, utilizes grooves numerous on the cylinder and circumferential slit to collect the liquid that membrane filtration gets off; Film rapid expanding under the effect of backwashing water or gas is circle-shaped during backwash, and the impurity that is attached on the film is cleaned under backwashing pressure and the effect of film expansive force totally.This filter core can use in groups and be installed on the filter, both can filter the liquid of low suspension, also can filter the liquid of high suspended matter, and can collect, dry up this suspension, consist of a kind of filling area large, backwash effect is good, and can effectively reclaim the self-cleaning membrane filter of filter cake, has very large market prospects.
Description of drawings
Fig. 1 is that embodiment of the utility model is installed in the structural profile schematic diagram in the filter.
Fig. 2 is Fig. 1 A section enlarged drawing.
Fig. 3 is the schematic cross-section of filter core under filtration condition.
Fig. 4 is the schematic cross-section of filter core under the backwash state.
The utility model will be further described below in conjunction with embodiment:
Fig. 1～Fig. 2 is that embodiment of the utility model is installed in the structural profile schematic diagram in the filter.Among the figure, a kind of self-cleaning membrane filter filter core, it includes: some filter core monomers 1, drain pipe 3; Described filter core monomer is comprised of film 11, inner support 12, stalk 13, inner support 12 forms, is on the outer cylinder that the petal type structure is distributed on stalk 13 by some hollow tube disjunctors that are column, the petal number is six lobes in the present embodiment, inner support 12 upper bases are connected with stalk 13 outer fringe seals, go to the bottom sealing, inner support 12 each hollow tube of inner support 12 managed the ends by pipe base space and stalk 13 and is communicated with, and has some phases circumferential slit 14 across a certain distance along its axis direction on the inner support 12 petal type outer cylinders; Described film 11 is made the filter cylinder shape, is covered on the inner support 12 petal type outer cylinders, and film 11 upper/lower terminals and inner support 12 are tightly connected, and the stalk of described each inner support 12 is sealedly connected on the drain pipe 3.
The utility model is further taked following measure: be furnished with vertical groove 15 on the described inner support petal type outer cylinder.
The utility model is like this work:
Filter process as shown in Figure 3, liquid sees through film by the outside of crossing filter core, is pooled to the groove on the inner support, and successively by finedraw, petal hollow tube inner tube, stalk is flowed out by the stalk upper end at last.Film is close to the petal inner support and also is petal-shaped under the effect of filtration pressure difference, the particle in the liquid is intercepted at film surface.Can select the film of different model to satisfy to filtering accuracy filtration temperature, the needs of filter medium.
Backwash process is as shown in Figure 4: by the downward flow at high speed in stalk top, by petal hollow tube inner tube, finedraw is the backwash film fast and evenly under the effect of hydraulic pressure or air pressure for backwash liquid when pressure reduction or time reach setting value.Film is under the effect of backwashing water or gas, be circle-shaped by the petal-shaped rapid expanding, impurity is cleaned under backwashing pressure and the effect of film expansive force totally, each organizes successively backwash of filtrate pipe, also can add filter aid during backwash, form cake filtration with filter aid at film, improve filtering accuracy.
The above reaches by reference to the accompanying drawings embodiment and has described embodiment of the present utility model; the structure that embodiment provides does not consist of restriction of the present utility model; those skilled in the art can show and need to adjust according to real in this area, make within the scope of the appended claims various distortion or modification all in protection domain.
