Abstract
The utility model discloses an improved filter membrane which comprises a filter membrane body, wherein three through holes are formed on the filter membrane body along the length direction thereof, a filtration passage comprises hole walls formed between each hole and the outside and hole walls formed between every two adjacent holes, and the area of the filtration passage is larger, thus the filtration effect is better. The diameter of the filter membrane body ranges from 2.5 mm to 6.5 mm, and the interior diameters of the three through holes range from 0.5 mm to 1.2 mm, therefore, the structural strength and the pressure-proof performance of the filter membrane are greatly enhanced, and the phenomenon of filament breakage does not easily occur during the application of the filter membrane.
Description
Technical field
The utility model relates to the membrane separation technique field, is specifically related to a kind of filter membrane.
Background technology
Membrane separation technique is that the microcellular structure by the film surface carries out Selective Separation to material.When liquid mixture is flowed through the film surface under certain pressure, little molecule solute sees through film (being called counter-infiltration liquid), macromolecular substances then is trapped, and makes in the stoste big molecular concentration improve (being called concentrate) gradually, thereby realizes the separation of large and small molecule, the purpose that concentrates, purifies.Membrane separation technique is remarkable with its energy-saving effect, equipment is simple, easy to operate, control easily and be subjected to users' popular welcome.
Filter membrane commonly used now is a hollow-fibre membrane, because it is the single hole structure, filtration channel has only the hole wall of this single hole, and the filtration channel area is less, and filter effect is not very desirable.And the hollow-fibre membrane diameter of this single hole structure less (diameter＜0.5mm), structural strength is lower, voltage endurance capability a little less than, the situation of fracture of wire takes place in regular meeting in the use.
The utility model content
The purpose of this utility model provides the improved filter membrane that a kind of filter effect is better and structural strength is higher, voltage endurance capability is stronger.
The technical solution of the utility model is such: a kind of improved filter membrane, comprise the filter membrane body, and above-mentioned filter membrane body runs through along its length direction and offers three through holes.
The diameter 2.5 of above-mentioned filter membrane body
-6.5mm the internal diameter of above-mentioned three through holes is 0.5
-1.2mm.
Above-mentioned three through holes are the position distribution at three angles of equilateral triangle on the cross section of above-mentioned filter membrane body.
After adopting such scheme, improved filter membrane of the present utility model, the diameter of filter membrane body are 2.5
-6.5mm the internal diameter of three through holes is 0.5
-1.2mm, strengthened its structural strength and voltage endurance capability greatly, in the middle of using, be difficult for fracture of wire.And in the utility model, the filter membrane body runs through along its length direction and offers three through holes, and filtration channel not only comprises hole wall between each hole and the external world, also comprises the hole wall between the adjacent holes, and the filtration channel area is bigger, thereby filter effect is better.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of improved filter membrane of the utility model, as shown in Figure 1, comprise filter membrane body 1, filter membrane body 1 runs through along its length direction and offers three through holes 11,12,13, and through hole 11,12,13 is the position distribution at three angles of equilateral triangle on the cross section of filter membrane body 1.
Wherein, the diameter of filter membrane body 1 is 2.5mm, and the internal diameter of through hole 11,12,13 is 0.5mm.Or the diameter of filter membrane body 1 is 3.2mm, and the internal diameter of through hole 11,12,13 is 0.7mm.Or the diameter of filter membrane body 1 is 4.5mm, and the internal diameter of through hole 11,12,13 is 0.9mm.Or the diameter of filter membrane body 1 is 6.5mm, and the internal diameter of through hole 11,12,13 is 1.2mm.
Claims (3)
1, a kind of improved filter membrane comprises the filter membrane body, it is characterized in that: above-mentioned filter membrane body runs through along its length direction and offers three through holes.
2, a kind of improved filter membrane according to claim 1 is characterized in that: the diameter 2.5 of above-mentioned filter membrane body
-6.5mm the internal diameter of above-mentioned three through holes is 0.5
