Abstract
The utility model provides a multilayer ultrafilteration membrane with irregular inner holes, which aims to solve the problem that the existing ultrafilteration membrane is low in utilization ratio when used for liquid separation due to unreasonable arrangement of coarse filter layers and fine filter lays. The multilayer ultrafilteration membrane with irregular inner holes comprises a multilayer ultrafilteration body, the cross section of the multilayer ultrafilteration body is in the shape of irregular curves and sizes of filter holes are gradually decreased from the utmost layer to the innermost layer, and separating liquid entering from the outermost layer can be filtered layer by layer so as to be separated and cleaned.
Description
Technical field
The utility model relates to the irregular milipore filter of a kind of multilayer endoporus, belongs to water treatment field.
Background technology
Chinese patent: 200820108527.6 disclose a kind of seven apertures in the human head PVC milipore filter, comprise ultrafiltration body in a tubular form, be provided with a plurality of holes in the ultrafiltration body, can be divided into alternate close filtering layer and thin filtering layer in the ultrafiltration body, be provided with some thin cavitys in the close filtering layer, dredge in the filtering layer and be provided with some thick cavitys.The milipore filter of this kind structure causes the utilization rate of milipore filter when fluid separation applications low, the cost height because arranging of thin filtering layer and close filtering layer is unreasonable.
The utility model content
The utility model provides a kind of multilayer endoporus irregular milipore filter for solving the prior art problem.
The technical solution of the utility model is: comprise the ultrafiltration body that is provided with multilayer, the shape of cross section of ultrafiltration body is that the size of irregular curve and its filtering holes is successively decreased from the outermost layer to the internal layer successively.Liquid to be separated enters from outermost layer, successively filters, and can realize the isolation of purified of liquid.
In sum, the utlity model has following advantage:
The effective filtration area of milipore filter is big, can realize separating step by step, and the utilization rate height of film can reduce unnecessary waste, reduces cost.
Description of drawings
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model;
Fig. 2 is the partial schematic diagram of ultrafiltration body interior laminate layer structure of the present utility model.
Among the figure, 1, the coarse filtration layer, 2, middle filtering layer, 3, filter bed of essence, 4, the coarse filtration hole, 5, middle filter opening, 6, smart filter opening.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, pending liquid is that coarse filtration layer 1 outside of irregular curve enters from shape of cross section, and 4 filter through the coarse filtration hole, filtering layer 2 in entering again, through in consider hole 5 and filter, flow into filter bed of essence 3 at last, filter by smart filter opening 6, so be a working cycles.In the present embodiment, pending liquid filters through coarse filtration layer 1 and middle filtering layer 2, and impurity content has reduced greatly in the pending liquid, can effectively must reduce the live load of filter bed of essence, thereby the total membrane area of filter bed of essence 3 can significantly reduce, and can effectively must reduce cost.And the shape of cross section of each layer is irregular, can effectively increase membrane area.
Claims (2)
1. the irregular milipore filter of multilayer endoporus comprises the ultrafiltration body that is provided with multilayer, it is characterized in that: the shape of cross section of described ultrafiltration body is that the size of irregular curve and its filtering holes is successively decreased from the outermost layer to the internal layer successively.
2. the irregular milipore filter of a kind of multilayer endoporus according to claim 1, it is characterized in that: described ultrafiltration body has three layers, is followed successively by the coarse filtration layer from outside to inside, middle filtering layer, filter bed of essence.
