Abstract
The utility model discloses a kind of circular film filter, comprise diaphragm, the support of fixing diaphragm; Described diaphragm is circular film, is equidistantly symmetrically distributed with 4-8 solder joints between circular film and circular film along its circumference, and the circular film of support both sides passes through the bonding connection in adhesion zone with the part between solder joint between circular film.The technical program is by being circular film by former octagonal diaphragm arrangement, and the circumference of circular film arranges 4-8 solder joint, and above-mentioned solder joint can be realized by hot melting way, fixes circular film by solder joint, and the adhesion zone between solder joint is connected by bonding.Above-mentioned improvement obtains the technique effect of following two aspects: the first, and technical difficulty and the assembly cost of assembling diaphragm reduce, and the efficiency of assembling improves; The second, add the effective filtration area of diaphragm.
Description
Technical field
The utility model relates to a kind of parts of reverse osmosis unit, specifically a kind of matrix of reverse osmosis unit.
Background technology
Counter-infiltration is a kind of by means of selecting to be the membrane separation technique of motive force with pressure through the skill of (semi-permeable) property film, when pressure added in system is greater than into water solution osmotic pressure, hydrone is constantly through film, central tube is flowed into through producing water flow passage, then at one end flow out the impurity in water, as ion, organic matter, bacterium, virus etc., be trapped within the influent side of film, then flow out in dense water water side, thus reach isolation of purified object.
Existing diaphragm is made up of the regular polygon reverse osmosis membrane of two concentric eight angle types, and wherein the front of two films is opposing, the thread support of film sandwich one deck, and the outer shroud welding of this shellring shape material, inner ring opening is pure water inlet.In above-mentioned manufacturing process, start along of a film angle to weld each limit successively, welding difficulty is large, and reliability is low, and welding cost is high.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of circular film filter, the film of this filter is rounded, its marginal portion is provided with solder joint, part between solder joint is combined by bonding mode, to reduce welding difficulty, reduces welding cost, improve manufacturing speed and the efficiency of film device, improve the reliability that die worker does simultaneously, increase the processing area for the treatment of apparatus mould, improve treatment effect.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of circular film filter, comprises diaphragm, the support of fixing diaphragm; Described diaphragm is circular film, is equidistantly symmetrically distributed with 4-8 solder joints between circular film and circular film along its circumference, and the circular film of support both sides passes through the bonding connection in adhesion zone with the part between solder joint between circular film.
The technical program is by being circular film by former octagonal diaphragm arrangement, and the circumference of circular film arranges 4-8 solder joint, and above-mentioned solder joint can be realized by hot melting way, fixes circular film by solder joint, and the adhesion zone between solder joint is connected by bonding.Above-mentioned improvement obtains the technique effect of following two aspects: the first, and technical difficulty and the assembly cost of assembling diaphragm reduce, and the efficiency of assembling improves; The second, add the effective filtration area of diaphragm.
As the further improvement to the technical program, the width in described circular film marginal adhesion district is 4-5mm.
As the further improvement to the technical program, described support is circular, the little 2-3mm of radius of the radius ratio circular film of support.
By above-mentioned setting, during circular film assembling, adhesion zone has at least a part to be that circular film is mutually bonding with circular film, and another part of adhesion zone is mutually bonding with support respectively, to improve bonding stability.
As the further improvement to the technical program, the surface at the edge of described support is provided with bonding grid, and described bonding grid and an inner side part for adhesion zone overlap.
As the further improvement to the technical program, described bonding grid is spacedly arrange interlaced grid, is open-work between grid and grid.Bonding effect can be increased further by above-mentioned setting.

Detailed description of the invention
Connection with figures is described in further detail the utility model below.
Index map 1, Fig. 2 are known, are octagonal diaphragm 1 in prior art, and diaphragm is octagon, and the both sides that two diaphragms are oppositely arranged on support 2 form one group of diaphragm filtration unit.It starts welding along the angle point of octagonal diaphragm 1 in an assembling process, welds successively to each limit, and welding difficulty is large, and reliability is low, and welding cost is high.
Index map 3, Fig. 4 are known, diaphragm of the present utility model is circular film 3, equidistantly be symmetrically distributed with 4 solder joints 4 along its circumference between circular film 3 and circular film 3, the circular film 3 of support 2 both sides passes through the bonding connection in adhesion zone 5 with the part between solder joint 4 between circular film 3.
If the more above-mentioned solder joint 4 of the diameter of circular film 3 can increase to 6 or 8, with improve bonding before, the stability that circular film 3 position is fixing.The width in circular film 3 marginal adhesion district 5 is 4-5mm.Described support 2 is circular, the little 2-3mm of radius of the radius ratio circular film 3 of support 2.
Composition graphs 4 is known, and the surface at the edge of the utility model support 2 is provided with bonding grid, and described bonding grid and an inner side part for adhesion zone 5 overlap.Described described bonding grid is spacedly arrange interlaced grid 6, is open-work 7 between grid 6 and grid 6.
