In the above-described embodiments, filtration membrane cartridge comprises rack body and installation parts, the middle part of rack body is provided with water-dilution channel, and between water-dilution channel and the outside surface of rack body, there is gap, sewage can flow in water-dilution channel from this gap, effluent stream is when rack body, under the effect of rack body, dirt in sewage is piled up gradually, form the filtering membrane with certain thickness and degree of compactness, this filtering membrane can filter sewage, along with sewage flows through rack body gradually, dirt on filtering membrane is piled up gradually, when the thickness of filtering membrane and degree of compactness reach preset value, the quality of the water after filtration after membrane filtration meets preset standard, now the filtering membrane of stable state is formed, installation parts is connected with the upper end of rack body, to be fixed on vertically on retaining plate by rack body, the water in water-dilution channel after filtering retaining plate offers the first through hole be connected with water-dilution channel, so that from the first through hole process, then can discharge tank body from water outlet.
In a concrete example, as shown in Figure 3, described rack body comprises oscillator unit 200, web member 203 and sealing plate 202.
Wherein, as shown in Figure 6, described oscillator unit 200 comprises multiple sheet 201 that shakes stacked successively, the described middle part shaking sheet 201 is provided with third through-hole 2010, and the described third through-hole 2010 of the sheet 201 that shakes described in multiple is connected, and forms the water-dilution channel 2000 of described rack body, the thickness of sheet 201 of shaking described in adjacent is not identical, and described in shake the thickness of sheet 201 between 0.1 ~ 0.6mm, with make water flow through described in shake sheet 201 surperficial time, described in the sheet 201 that shakes produce vibration;
Described web member 203 connect successively multiple described in shake sheet 201, described sealing plate 202 is positioned at the lower end of described rack body, and seals the lower end of described water-dilution channel 2000.
In above-described embodiment of the present utility model, in oscillator unit, the thickness of the adjacent sheet that shakes is not identical, according to fluid structurecoupling principle (solid produces deformation or motion under the effect of fluid-load), current are when the sheet that shakes surperficial, make sheet generation vibration of shaking, form wave of oscillation, this wave of oscillation can apply and water (flow) direction opposite effect power the dirt in sewage, dirt is pushed away the surface of rack body, dirt is under the acting in conjunction of wave of oscillation and current, remain on the setpoint distance place of distance bracket body outer surface, the setpoint distance place outside filtration membrane cartridge outside surface is gathered in gradually along with dirt, define filtering membrane.
The thickness of the adjacent sheet that shakes is not identical, the wave frequency that the sheet that shakes vibration produces is not identical yet, cancel out each other after avoiding the ripple superposition of same frequency, dirt can not be pushed away the outside surface of rack body, and then filtering membrane can not be formed at the setpoint distance place of distance bracket body outer surface.
It should be noted that, when the thickness of filtering membrane and degree of compactness do not reach preset value, filtering membrane can not filter effectively to sewage, and the water now flowing through the sheet surface that shakes is sewage; When the thickness of filtering membrane and preset value reach preset value, effectively can filter sewage, the water now flowing through the sheet surface that shakes is the clear water after filtering.
Further, described rack body comprises multiple described oscillator unit 200 stacked successively, multiple described oscillator unit 200 couples together by described web member 203, sealing plate 202 is fixed on the lower end of rack body by web member 203, and the lower port of water-dilution channel is sealed, clear water after filtration after membrane filtration can enter water-dilution channel, and discharges from the upper port of water-dilution channel.
In a preferred embodiment of the present utility model, in described oscillator unit 200, shake described in adjacent between sheet 201 and be provided with strut member.
In a concrete example, the projection 2011 of described strut member for shaking on sheet 201 described in being arranged on.
Shake on sheet and be provided with projection, make adjacent shaking between sheet have enough gaps, thus ensure that the surface of enough current through the sheet that shakes, namely ensure that glassware for drinking water has enough large load to be applied to and shakes on sheet, the sheet that enables to shake produces vibration.
In addition, during the sheet that shakes vibration, this projection of shaking on sheet can be knocked and the adjacent sheet that shakes, make the adjacent sheet that shakes produce vibration, when the adjacent sheet that shakes vibrates, the projection on it can apply a surging force conversely to this sheet that shakes, enhance the vibration of this sheet that shakes, Circulation like this, enhance the effect of sheet vibration of shaking.
In of the present utility model one concrete example, as shown in Figure 5, described in shake on sheet 201 and be provided with multiple described protruding 2011, multiple described protruding 2011 along described in shake the uniform setting of circumference of sheet 201;
Further, as shown in Figure 2 and Figure 5, described in the sheet 201 that shakes to shake sheet for circle, described third through-hole 2010 is manhole; In described oscillator unit 200, described protruding 2011 on the sheet 201 that shake described in adjacent shake described in same projection on sheet 201 line only described in shake the center of circle of sheet 201.
With water along the radial flow of the sheet that shakes compared with the surface of the sheet that shakes, the setting of sheet projection of shaking, the path of current warp is bent, thus the length of effluent stream through the path on the sheet surface that shakes is extended, add the effect duration of load to the sheet that shakes of water, the energy being passed to the sheet that shakes like this is more, and the vibration Shaoxing opera of the sheet that makes to shake is strong.
In of the present utility model one concrete example, in described oscillator unit, the preglabellar field (as shown in Figure 4 and Figure 6) of the sheet that shakes described in adjacent is all not concordant with outward flange (as shown in Figure 3 and Figure 6).
In a concrete example, as shown in Figure 4 and Figure 6, the aperture of the described third through-hole 2010 of the sheet 201 that shakes described in adjacent is not identical, and the preglabellar field injustice of the adjacent sheet 201 that shakes is risen.
Because the aperture of the third through-hole of the adjacent sheet that shakes is not identical, namely the inwall of water-dilution channel is uneven, water in water-dilution channel on flowing, by different pore size shake sheet time, one reactive force is applied to the sheet that shakes, make sheet generation vibration of shaking, under the acting in conjunction that the vibration produced in this vibration and fluid structurecoupling, protruding enhancing are vibrated, outside reactive force (namely contrary with water (flow) direction power) is applied to the dirt in sewage or filtering membrane, simultaneously under the effect of current, the dirt in sewage or filtering membrane remain on the setpoint distance place of rack body outside surface.
In another concrete example of the present utility model, described in shake sheet 201 preglabellar field on be provided with the first groove (not shown), described first groove shaken described in adjacent on sheet 201 is crisscross arranged, and the preglabellar field of the sheet 201 that makes to shake is not concordant; And/or, described in shake sheet 201 outward flange on be provided with the second groove (not shown), described second groove shaken described in adjacent on sheet 201 is crisscross arranged, and the outward flange of the sheet 201 that makes to shake is not concordant.
