Be provided with the interval passed through for sewage between inner sleeve lower surface and bottom end cover, be provided with inner flow passage between water diversion disk and inner sleeve, inner flow passage is communicated with outer flow passage by interval, is provided with the concentrated solution outlet be communicated with inner flow passage above upper end cover;
Inner sleeve inside is provided with water diversion disk that is side by side some and the connection that is spirally connected mutually, be spirally connected in the middle part of water diversion disk topmost and upper end cover, be spirally connected in the middle part of water diversion disk bottom and bottom end cover, above water diversion disk and be equipped with below for filtration membrane, be provided with the permeate be communicated with water diversion disk inside topmost above upper end cover and export.
As preferably, be provided with the fluid sleeve that be communicated with inner with water diversion disk topmost above upper end cover, permeate exports and is positioned at outside on fluid sleeve.
As preferably, be provided with draw-in bar in inner sleeve, draw-in bar upper end is through fluid sleeve, and draw-in bar lower end is through bottom end cover.
As preferably, draw-in bar two ends are equipped with the external screw thread being convenient to install fixing whole membrane module.
As preferably, draw-in bar is stainless steel.
the beneficial effects of the utility model are:
1, bearing shell of the present utility model and inner sleeve upper end and upper end cover are spirally connected, and bearing shell lower end and bottom end cover are spirally connected, and are provided with the inlet entered for sewage above upper end cover, are provided with the outer flow passage be communicated with inlet between bearing shell and inner sleeve; Be provided with the interval passed through for sewage between inner sleeve lower surface and bottom end cover, be provided with inner flow passage between water diversion disk and inner sleeve, inner flow passage is communicated with outer flow passage by interval, is provided with the concentrated solution outlet be communicated with inner flow passage above upper end cover; Inner sleeve inside is provided with the side by side some and water diversion disk be communicated with that is spirally connected mutually, above water diversion disk and be equipped with below for filtration membrane, is provided with the permeate be communicated with water diversion disk inside topmost and exports above upper end cover.Due to the effect of high pressure, sewage forms high velocity turbulent flow after getting to the salient point on water diversion disk, film surface not free settling pollutant under the washing away of this turbulent flow, thus it is contaminated to make membrane surface be not easy fouling.Be fixed on side by side some and on the water diversion disk that is communicated with of being spirally connected mutually the area summation of diaphragm, much larger than the diaphragm area of rolled membrane module, from but the efficiency of membrane module filter sewage very significantly improve.
2, be provided with draw-in bar in inner sleeve of the present utility model, draw-in bar upper end is through fluid sleeve, and draw-in bar lower end is through bottom end cover, and draw-in bar two ends are equipped with the external screw thread being convenient to install fixing whole membrane module.By draw-in bar, fixing membrane module is installed convenient, membrane module can be made to fix more firm.
3, draw-in bar of the present utility model is stainless steel, and the draw-in bar of stainless steel is more corrosion-resistant, not fragile when filtration treatment has corrosive sewage.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, the present embodiment provides a kind of flat reverse osmosis membrane assembly, comprise upper end cover 6, bottom end cover 14, draw-in bar 3, bearing shell 7 and be positioned at the inner sleeve 8 of bearing shell 7 inside, bearing shell 7 and inner sleeve 8 upper end and upper end cover 6 are spirally connected, bearing shell 7 lower end and bottom end cover 14 are spirally connected, upper end cover 6 is provided with the inlet 1 entered for sewage above, is provided with the outer flow passage 10 be communicated with inlet 1 between bearing shell 7 and inner sleeve 8.
The interval 13 passed through for sewage is provided with between inner sleeve 8 lower surface and bottom end cover 14, inner flow passage 11 is provided with between water diversion disk 9 and inner sleeve 8, inner flow passage 11 is communicated with outer flow passage 10 by interval 13, and upper end cover 6 is provided with the concentrated solution outlet 2 be communicated with inner flow passage 11 above.
Inner sleeve 8 inside is provided with water diversion disk 9 that is side by side some and the connection that is spirally connected mutually, be spirally connected in the middle part of water diversion disk topmost 9 and upper end cover 6, be spirally connected in the middle part of water diversion disk 9 bottom and bottom end cover 14, above and be equipped with for filtration membrane 12 below, upper end cover 6 is provided with the permeate be communicated with water diversion disk 9 inside topmost above and exports 5 water diversion disk 9.
Upper end cover 6 is provided with the fluid sleeve 4 be communicated with water diversion disk 9 inside topmost above, and permeate outlet 5 is positioned at outside on fluid sleeve 4.Be provided with draw-in bar 3 in inner sleeve 8, draw-in bar 3 upper end is through fluid sleeve 4, and draw-in bar 3 lower end is through bottom end cover 14.Draw-in bar 3 two ends are equipped with the external screw thread being convenient to install fixing whole membrane module.Draw-in bar 3 is stainless steel.
In implementation process, it is inner that sewage enters bearing shell 7 from the inlet 1 above upper end cover 6, sewage flows into the outer flow passage 10 between bearing shell 7 and inner sleeve 8, and the sewage in outer flow passage 10 enters the inner flow passage 11 between water diversion disk 9 and inner sleeve 8 by interval 13.Impurity in diaphragm 12 filtering sewage on water diversion disk 9 is above and below, the water of filtering impurity enters water diversion disk 9 and flows out from the permeate outlet 5 fluid sleeve 4.The concentrated solution outlet 2 that upper end cover 6 is communicated with inner flow passage 11 above, discharges the concentrate containing a large amount of impurity.
Due to the effect of high pressure, sewage forms high velocity turbulent flow after getting to the salient point on water diversion disk 9, diaphragm 12 surface not free settling pollutant under the washing away of this turbulent flow, thus it is contaminated to make diaphragm 12 surface be not easy fouling.Be fixed on side by side some and on the water diversion disk 9 that is communicated with of being spirally connected mutually the area summation of diaphragm 12, much larger than the diaphragm area of rolled membrane module, the diaphragm area for filter sewage greatly improves, from but the efficiency of membrane module filter sewage very significantly improve.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
