Abstract
The utility model discloses a kind of doughnut flat sheet membrane, comprise collector pipe, lower collector pipe, support bar and lamina membranacea, described support bar is between upper collector pipe and lower collector pipe, on described upper collector pipe and lower collector pipe, be provided with the encapsulation groove that lamina membranacea is installed, described lamina membranacea is comprised of base material and the hollow fiber film thread that is bonded on base material by glue.The utility model is used the alternative traditional membrane material brushing of hollow-fibre membrane to prepare flat sheet membrane, and advantage is as follows: rete is thick, safeguards that pressure limit is little, can carry out backwash maintenance, and the flexible maintenance effects of maintenance mode is better; The thick resistance to erosion of rete and hydraulic blow, do not produce de-face phenomenon without base material and membrane coat faying face, and product quality is more stable; It is easy, with short production cycle that materials are economized the few mode of production of accessory; Owing to making for doughnut, outer surface is curved surfaces, has increased total surface area.
Description
Technical field
The utility model relates to milipore filter product technical field, especially a kind of doughnut flat sheet membrane.
Background technology
Current flat sheet membrane is the plastic board with geosynclinal concave by die sinking manufacture, on dull and stereotyped two sides, use the fixedly multi hole surface base material such as nonwoven of glue, again at the compound of the outer brushing membrane material of the base material such as nonwoven and solvent composition, utilize the process of solvent evaporates, make membrane material solidify to form fenestra, make flat sheet membrane part.During use, flat sheet membrane part is immersed in membrane cisterna, is connected to the inlet of plastic board by suction pump, water is seen through to film extraction and obtain producing water, the material tunicle in water is held back and is rested in membrane cisterna.
This mode of production cost is large, and the low easy breakage of washing away of thicknesses of layers, can not be used backwash to carry out General Maintenance, and chemical cleaning online also exists not resistance to wash pressure, the problem of chemical cleaning online medicament water distribution inequality.Owing to being plane masking, film support section is as glue standing part; Base material will inevitably tie up the area of film as the train of thought of nonwoven.
Summary of the invention
The technical problems to be solved in the utility model is: the problem for the prior art solving in above-mentioned background technology exists, provides a kind of improved doughnut flat sheet membrane.
The utility model solves the technical scheme that its technical problem adopts: a kind of doughnut flat sheet membrane, comprise collector pipe, lower collector pipe, support bar and lamina membranacea, described support bar is between upper collector pipe and lower collector pipe, on described upper collector pipe and lower collector pipe, be provided with the encapsulation groove that lamina membranacea is installed, described lamina membranacea is comprised of base material and the hollow fiber film thread that is bonded on base material by glue.
Further, described base material is nonwoven or hard plate material.
Further, described support bar is rigid plastics bar or Metallic rod.
The beneficial effects of the utility model are, the utility model is used hollow-fibre membrane to substitute traditional membrane material brushing to prepare flat sheet membrane, and advantage is as follows:
1, rete is thick, safeguards that pressure limit is little, can carry out backwash maintenance, and the flexible maintenance effects of maintenance mode is better;
2, the thick resistance to erosion of rete and hydraulic blow, do not produce de-face phenomenon without base material and membrane coat faying face, and product quality is more stable;
3, the few mode of production of materials province accessory is easy, with short production cycle;
4, owing to making for doughnut, outer surface is curved surfaces, has increased total surface area.。
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view of lamina membranacea in the utility model.
In figure: 1. go up collector pipe, 1 '. lower collector pipe, 2. support bar, 3. lamina membranacea, 4. encapsulation groove, 5. base material, 6. hollow fiber film thread.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Fig. 1～2, a kind of doughnut flat sheet membrane, a kind of doughnut flat sheet membrane, comprise collector pipe 1, lower collector pipe 1 ', support bar 2 and lamina membranacea 3, support bar 2 upper collector pipe 1 and lower collector pipe 1 ' between, upper collector pipe 1 and lower collector pipe 1 ' be above provided with are installed the encapsulation groove 4 of lamina membranacea 3, and lamina membranacea 3 is comprised of base material 5 and the hollow fiber film thread 6 that is bonded on base material 5 by glue, and base material 5 is nonwoven.
The present embodiment is to use glue to be directly fixed on base material 5 hollow fiber film thread 6, and hollow fiber film thread 6 two ends are used glue shutoff to enter collector pipe 1 and made doughnut flat sheet membrane.Specific process is:
1, hollow fiber film thread 6 tilings are organized into one deck of plane, smooth laying after two ends clamping plate are fixing;
2, non-woven fabrics base material 5 tilings, spreading glue layer;
3, the non-woven fabrics base material of spreading glue layer 5 is covered on hollow fiber film thread 6 along cambered surface is smooth, constant temperature and humidity solidifies;
4, above-mentioned non-woven fabrics base material 5 faces that cover hollow fiber film thread 6 are glued together between two, make a lamina membranacea 3;
5,3 liang of end-grain cutting of lamina membranacea are concordant, pack in the encapsulation groove 4 of collector pipe 1 mucilage sealing caulking joint gap;
6: collector pipe 1 both sides are used rigid plastics bar to support, and are strained and fixed and make lamina membranacea 3 planes smooth, make finished product and preserve.
In addition, can use hard plate material to substitute nonwoven as base material 5, or use screen material by the fixing two ends again tension of hollow fiber film thread 6 planes.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
