Abstract

The utility model relates to a filling in the field of treating water, wastewater or sewage. Under the state of hot melt, the multivariable net-shaped solid filling of the utility model is crosswise connected by plastic strips or plastic threads into a solid net in a hollow column shape, a sheet shape or other geometric shapes in a solid mode. The utility model has the advantages of uniform distribution, favorable performance of central ventilation and central water flowing, strong mechanical strength, long service life, etc., and no centre piece is needed; therefore, the utility model can be widely used for various water treating and cooling devices.

Description

The netted 3-D filler of Changeful type

The utility model relates to the filler of water, waste water or sewage treatment area.

No matter the filler that is used for water, waste water or sewage treatment area now is hard filler, soft-filler, semi soft packing, combined stuffing, elastic filler, and ubiquity easily filling, centrepiece easy fracture, lack of homogeneity, defective such as the utiliztion ratio surface-area is little.Particularly after the biofilm conglomeration, whole filler has become a cylinder, and middle no through hole can't oxygen supply, makes treatment effect decline.Because springy texture can not wash and reuse, and work-ing life is shorter, change frequent again.

The purpose of the utility model be to provide a kind of homogeneity better, the utiliztion ratio surface-area more greatly, can not stop up, new packing that work-ing life is long.

The netted 3-D filler of Changeful type is the three-dimensional stereoscopic graticule of forming hollow column type, sheet type or other several shapes of handing under the hot melt state by plastic strip or plastics silk.

Below in conjunction with embodiment shown in the drawings, the utility model is explained in detail.

Accompanying drawing the 1,3,5, the 6th, the front view of the utility model embodiment one, two, three, four, accompanying drawing the 2,4, the 7th, the local stretch-out view of the utility model embodiment one, two, four.

Shown in accompanying drawing 1 to 7, the netted 3-D filler of Changeful type is the three-dimensional stereoscopic graticule of forming hollow column type, sheet type or other geometrical shapies of handing under the hot melt state by plastic strip or plastics silk 1.Embodiment one and two shown in attached Fig. 1 and 2,3 and 4 is hollow column type stereoscopic graticules, and the embodiment three shown in the accompanying drawing 5 is sheet type stereoscopic graticules, and the embodiment four shown in the accompanying drawing 6 and 7 is other geometrical shapies---semicircle stereoscopic graticule.

Shown in accompanying drawing 1 to 7, rounded, the quasi-circular of cross-sectional shape of plastic strip or plastics silk 1, perhaps flat, perhaps other geometrical shapies.

Shown in accompanying drawing 2,4,5 and 7, the mesh 2 of stereoscopic graticule is a rhombus, and is perhaps square, perhaps circular, perhaps other geometrical shapies.Accompanying drawing 2,5 and 7 is rhombuses, and wherein the rhombus limit of accompanying drawing 2 is hypotenuses, hypotenuse of the straight flange in the rhombus limit of accompanying drawing 5, hypotenuse of the horizontal edge in the rhombus limit of accompanying drawing 7.Accompanying drawing 4 is square, and square can certainly be a rectangle.

Because plastic strip of the present utility model or plastics silk 1 are three-dimensional interlacing, the net formula filler that does not resemble is that the plane is interlacing, so not only specific surface area is big, and the streamflow regime at filler center is good.The current at embodiment one, three and four filler centers are shape in the shape of a spiral, and embodiment two is linearly, can not cause turbulent flow, also can improve treatment effect.

Installation method of the present utility model mainly is the stacking formula, need not centrepiece.Can level stack, vertically piling also can tilt to stack.Another kind of mounting means is a suspension type, can be suspended on the support hollow column type filler is single, also sheet type filler can be suspended on the support, but and density regulated at will.Because this filler can wash repeatedly, reuse, thereby use the longevity to make longer.

Obviously, because the utility model is evenly distributed, do not need centrepiece, center ventilation water flowing is good, and physical strength is strong, and therefore long service life can be widely used in various water treatments and the refrigerating unit.

In the embodiment shown in the figures, the physical dimension of embodiment one is φ 10 * 1000, and example two is 8 * 8 * 800, and embodiment three is 50 * 1500, and the semicircle radius of embodiment four is 7, and length is 1000.
