Therefore, those skilled in the art have been devoted to developing a water purification ultrafiltration membrane module that is easy to clean.
Disclosure of Invention
In view of the above-mentioned drawbacks of the prior art, the present invention provides a water purification ultrafiltration membrane module that is easy to clean.
In order to achieve the purpose, the water purification ultrafiltration membrane assembly provided by the invention comprises a fixing ring, wherein a plurality of external-pressure type hollow fibers which are not communicated with each other are clamped by the fixing ring, the upper ends of the plurality of external-pressure type hollow fibers are clamped and tightly fixed in the fixing ring, the lower ends of the single external-pressure type hollow fibers freely float, the top of the single external-pressure type hollow fiber is provided with a water outlet, the bottom of the single external-pressure type hollow fiber is sealed, and the side wall of the single external-pressure type hollow fiber is provided with a water permeable micropore in a penetrating manner.
The aperture of the water-permeable micropores is 3-100 nm.
And adhesive is filled in gaps between the upper ends of the external pressure type hollow fibers and between the external pressure type hollow fibers and the fixing ring 1.
And the bottom of the single external pressure type hollow fiber is stuck and sealed in a hot melting mode.
And the bottom of each external pressure type hollow fiber is sealed by adopting an adhesive sticking mode.
The invention has the beneficial effects that: the water purification ultrafiltration membrane component comprises a fixing ring, wherein the fixing ring clamps a plurality of external-pressure hollow fibers which are not communicated with each other, the upper ends of the plurality of external-pressure hollow fibers are clamped and tightly fixed in the fixing ring, the lower end of a single external-pressure hollow fiber freely floats, a water outlet is formed in the top of the single external-pressure hollow fiber, the bottom of the single external-pressure hollow fiber is sealed, and a water through micropore penetrates through the side wall of the single external-pressure hollow fiber; during back flushing, purified water flows downwards from the water outlet through the water permeable micropores and permeates out to flush impurities attached to the surface of the external pressure type hollow fiber, so that the cleaning is convenient, the flushing difficulty is greatly reduced compared with the prior art, and the flushing cost is saved.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the present invention in a flushing configuration;
fig. 3 is a top view of the structure of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples, wherein the terms "upper", "lower", "left", "right", "inner", "outer", and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings, which is for convenience and simplicity of description, and does not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular manner, and thus should not be construed as limiting the present invention. The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1 to 3, a water purification ultrafiltration membrane assembly, including solid fixed ring 1, solid fixed ring 1 centre gripping has a plurality of external pressure type hollow fiber 2 that each other do not communicate, the upper end of a plurality of external pressure type hollow fiber 2 is closely fixed in solid fixed ring 1 by the centre gripping, the lower extreme of single external pressure type hollow fiber 2 is floated freely, the top of single external pressure type hollow fiber 2 is provided with delivery port 3, the bottom of single external pressure type hollow fiber 2 is sealed, the lateral wall of single external pressure type hollow fiber 2 runs through and is provided with the micropore that permeates water, in this embodiment, the micropore that permeates water's aperture is 3 ~ 100 nm.
In this embodiment, the gaps between the upper ends of a plurality of external pressure type hollow fibers 2 and between the external pressure type hollow fibers 2 and the fixing ring 1 are filled with adhesive 4, the fixing ring 1 and the external pressure type hollow fibers 2 are integrated by the adhesive 4, the structure is firm, and the sealing effect between the fixing ring 1 and the external pressure type hollow fibers 2 is good.
Further, there are two bottom sealing methods for the single external pressure type hollow fiber 2, one is that the bottom of the single external pressure type hollow fiber 2 is pasted and sealed by a hot melt method, and the other is that the bottom of the single external pressure type hollow fiber 2 is sealed by an adhesive pasting method.
In this embodiment, the fixing ring 1 may be of any geometric shape, so as to be conveniently suitable for different equipment requirements.
The working principle of the invention is as follows:
the water purification ultrafiltration membrane component has the same working principle as the existing water purification membrane on the market when water is purified, when the water purification working state is realized, the raw water submerges the lower end of the water purification ultrafiltration membrane component, the water outlet 3 is positioned above the water surface of the raw water, each external pressure type hollow fiber 2 is in a free state in the water and flows along with the water flow, thus impurities in the water cannot be accumulated among a plurality of external pressure type hollow fibers 2, and the raw water is filtered by the permeable micropores to obtain purified water which is discharged from the water outlet 3.
During back flush, the pure water passes through the micropore that permeates water from delivery port 3 and flows down and oozes out, erodes the impurity that attaches 2 surfaces at external pressure formula hollow fiber, moreover because rivers make external pressure formula hollow fiber 2 in the relation of aquatic free swing, still can rub each other between the external pressure formula hollow fiber 2 to also can rub the impurity that attaches 2 surfaces at external pressure formula hollow fiber, it is convenient to wash, more prior art greatly reduced washes the degree of difficulty, saved and washed the cost.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
