Reinforced hollow-fibre membrane silk
Technical field
The utility model relates to a kind of hollow-fibre membrane silk that is used for water treatment field, in particular, relates to a kind of reinforced hollow-fibre membrane silk with three capilar bore structures.
Background technology
Hollow-fibre membrane has obtained application in the field headed by the manufacturing of food industry, medical field, domestic water, sewage disposal etc.Particularly in recent years, even also bring into use hollow-fibre membrane in the industrial wastewater field of reclaiming.But existing hollow-fibre membrane silk is the single capillary structure, and permeable amount and film silk brute force have certain limitation, and in the utilization process, the hollow-fibre membrane silk easily is crushed, and then influences the overall mechanical properties and the service life of hollow-fibre membrane silk.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of permeable amount big, and the intensity height minimizes film rupture, prevents from that the film silk from breaking to cause the reinforced hollow-fibre membrane silk of the three capillary structure that former water sneaks into.
The utility model is achieved through the following technical solutions:
A kind of reinforced hollow-fibre membrane silk comprises hollow-fibre membrane silk body, it is characterized in that, described hollow-fibre membrane silk body interior is provided with three capilar bores, and the line of centres of described three capilar bores is formed equilateral triangle.
In order to make the film silk have extremely thin positive filtering surface, design has three inside circular arc sunk parts on the film silk outer wall, and the line at the summit of each circular arc sunk part and hollow-fibre membrane silk body center is divided the line of centres of adjacent two capilar bores equally.
The internal diameter of described capilar bore is 0.1-5.0mm, and the thickness between described capilar bore and the described hollow-fibre membrane silk body is 0.01-5.0mm.
The utlity model has following technique effect:
1. have three capilar bore supporting constructions in the hollow-fibre membrane silk body of the present utility model, the outside has three inside circular arc sunk parts, has extremely thin positive filtering surface, and permeable amount is big.
2. the line of centres of three capilar bores is formed equilateral triangle, helps keeping the uniformity of permeating.And, come stability greatly for the film silk ribbon, help improving the compression strength of film silk, have higher mechanical stability, film silk performance is improved, prevent that the film silk from breaking and cause former water to be sneaked into, thereby improve the service life of membrane module.
Description of drawings
Fig. 1 is the cutaway view of the reinforced hollow-fibre membrane silk of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The cutaway view of the reinforced hollow-fibre membrane silk of the utility model comprises hollow-fibre membrane silk body 3 as shown in Figure 1, is provided with three capilar bores 2 in hollow-fibre membrane silk body 3 inside. the line of centres of three capilar bores is formed equilateral triangle.Wherein, the internal diameter of capilar bore is 0.1-5.0mm, and the thickness between capilar bore 2 and the hollow-fibre membrane silk body 3 is 0.01-5.0mm.Evenly be provided with three inside circular arc sunk parts 1 on hollow-fibre membrane silk body 3 outer walls, the line at the summit of each circular arc sunk part and hollow-fibre membrane silk body center is divided the line of centres of adjacent two capilar bores equally.
Hollow-fibre membrane silk of the present utility model can be used for external-pressing film assembly, press mold assembly in also can being used for.When being used for external-pressing film assembly, former water sees through hollow-fibre membrane silk body and enters respectively in three capilar bores and become water purification, and during the press mold assembly, former water becomes water purification through the tube wall between three capilar bores and the hollow-fibre membrane silk body respectively when being used in.Water purification uses after collecting.
Although relate to a kind of reinforced hollow-fibre membrane silk and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
