Abstract
The utility model relates to an elastic filling for water treatment, belonging to the technical field of the water treatment. The utility model is composed of a centre piece and integrated pieces of elastic fiber continuously wound and fixed on the centre piece, wherein, the centre piece is a soft or a hard rope; the configuration of the elastic fiber thread can be a round shape, a flat shape and a wave shape, and the surface of the elastic fiber thread is provided with woolly grains. The utility model has the advantages of no agglomeration, long service life, large effective specific surface areas, easy film formation and stripping, favorable stability quality of the fillings, favorable performance of water distribution and gas distribution, simple manufacturing technique, low manufacturing cost, etc., threads are not dropped, and the utility model can be used for the field of the water treatment.
Description
A kind of novel water treatment elastic filler relates to the fixed elastic filler of using in the filler in the microbial film purifier, particularly trade effluent, sanitary sewage and the source water correction plant.
The existing fixed elastic solid filler that is used for water treatment field all is made up of centrepiece and spandex fiber, and its constructional feature roughly is divided into three kinds of situations: first spandex fiber is fixed on the centrepiece with mode such as twining, interspersed, bonding; It two is fixed on the pitch of fins formula filler of forming on the centrepiece of being made up of egative film, cover plate and retaining ring by being the spandex fiber that radiates sheet structure, then with the use that is together in series of assembling rope; It three is earlier spandex fiber to be made some spherical three-dimensional rings, is fixed in one by one then on the plastic stent of being made up of assembly hole, annulus, muscle, arc strip and the post that drips.These structures in the specific surface area that has all increased filler in varying degrees, improved demoulding biofilm, distribute water and air performance, overcome the shortcoming of conglomeration.But, because above-mentioned spandex fiber all is by the certain length of design requirements intercepting, each bundle spandex fiber of just forming filler is independent mutually, and it is also independent mutually between spandex fiber and the centrepiece, thereby in actual use because the turbulent fluctuation of current and the impulse force of bubble, the drawback of running easily takes place, and decontamination effect improving is descended.When the running situation took place, the centrepiece of elastic solid filler and spandex fiber all damaged or are aging, so the filler of changing during running often do not reach its real acceptable life as yet, had therefore shortened the filler replacement cycle, had increased running cost.Secondly, every spandex fiber needs by design requirements long filament to be cut into short silk in manufacturing processed, promptly need possess the chopping operation, makes filler production process complexity.
The purpose of this utility model is to provide a kind of novel elastic filler that falls silk anything but, when keeping the plurality of advantages of original elastic solid filler, give full play to filler effective work-ing life, further increase filler effective ratio area, improve the distribute water and air performance, letter economizes production process.
In order to achieve the above object, the utility model is realized by following scheme.Elastic filler comprises centrepiece and the spandex fiber composition of fixing on it.Its constructional feature is that spandex fiber adopts whole intersection to twine interspersed being fixed on the centrepiece, and centrepiece is a rope soft, hard.Diameter, the length of spandex fiber are made according to working conditions.
The utlity model has following advantage:
1. the whole rhizoid of spandex fiber interts and is fixed in the centrepiece, has solved the running problem of elastic solid filler in the past, and the time limit of service that has prolonged filler can make full use of the acceptable life of filler;
2. compare with original separate spandex fiber silk, elastic filler of the present utility model is equivalent to increase the contact part in the external end of each standalone elastic silk, the increase of this part, further increased the rigidity of the effective ratio area and the filler of elastic filler, its total specific surface area is further improved, and having increased the stability of filler, this will increase effective biomass accompanying on the filler, thereby strengthens the removal of water pollutant;
3. the increase of the contact of the external end of above-mentioned spandex fiber part, strengthened filler to the cutting action of current and bubble, improved its distribute water and air performance, thereby the mass transfer effect between aeration aerating efficient, air water and the biology all is improved, has finally improved the processing efficiency of filler;
4. the elastic yarn in every elastic filler is complete one, during production, under the identical condition of other each procedure, has saved and has made the required chopping operation of elastic solid filler in the past.
The utility model will be further described in conjunction with the accompanying drawings.
Fig. 1. be structural representation of the present utility model;
Fig. 2. be structural front view of the present utility model;
Fig. 3. be structure vertical view of the present utility model.
Elastic filler of the present utility model is made up of elastic filler silk 2 and centrepiece 1, the spandex fiber 2 that a surface is had a burr along the length direction of filler be interspersed in equably in the centrepiece 1 crossed loops around, and fixing by the tight back of centrepiece 1 strand.But the profile of spandex fiber 2 can be justified, can flat undaform, and raw material is that rebound performance is good, density is lower than 1 poly-third plastics of wire drawing level.The connection employing of every spandex fiber 2 that links up all the time and centrepiece 1 intersects winding, is interspersed in mode wherein.Because spandex fiber 2 is applied on the centrepiece 1 incessantly, centrepiece 1 is a rope soft, hard, and spandex fiber 2 is the centrosymmetry point with centrepiece 1, becomes 8 fonts to twine by double-ring, so each spandex fiber silk ring is divergent shape from the plane, whole elastic filler then is stereo structure.During use the two ends of its centrepiece 1 are fixed in the treatment unit and get final product.
Claims (3)
