Abstract

The utility model relates to a dynamic stereo spherical suspension packing which is formed by the injection moulding of polyethylene (polypropylene) materials. The spherical surface is composed of warps and wefts, the width of the warp and the weft is within the range of two to three millimeters, and the inner side of the sphere, in which the warp and the weft are separated at intervals of 30-50 millimeters is provided with reinforcing ribs. The height of each reinforcing rib is three to five millimeters, and the width is 1.5 millimeters. An equatorial surface and a round surface which passes through a vertical shaft center are arranged in the sphere, wherein the two surfaces are respectively composed of barriers, the spacing of the barriers is three to five millimeters, and the width of the barrier is two to three millimeters. The sphere is evenly divided into four net-shaped space by the equatorial surface and a vertical surface, and a hollow polyhedral sphere is arranged in each space. The sphere is dipped in a sewage pool to form the dynamic suspension packing.

Description

The dynamic solid spherical suspending filling material

A kind of dynamic solid spherical suspending filling material belongs to sewage disposal equipment, relates to environmental protection technical field.

In the treatment tank in the past; the fixed filler of many employings; having occurred the suspension filler recently, is monomer particle or monomer ball shape filler, although the latter has improvement than technology in the past; but when air-flow has fluctuation slightly; be easy to cause spheroid to pile up, form the not runny dead angle of difficult ventilation, thereby be directed at air-flow short circuit and bio anaerobic; the effect that filler is lowered or lost contact and exchanged has reduced sewage treatment capacity.

The utility model promptly designs for this reason, uses the spherical combined stuffing of a plurality of Hollow Compound bodies, improves the distribution of gas in the pond, reaches to be evenly distributed ventilation evenly, improves gas, liquid film mass transfer, thereby improves the water treatment effect.

The utility model is the netted hollow ball (1) that adopts 50～200 millimeters of diameters, this ball constitutes netted outer surface of ball by many warps (2) and parallel (2), the interval of warp and warp and parallel and parallel is controlled at 25～100 square millimeters with institute's shape voidage into the net, the width of every warp, parallel self is 2～3 millimeters, wherein, 30～50 millimeters two warps, the parallel of whenever being separated by is provided with stiffening web (3) in the spheroid inboard, the width of stiffening web is 1.5 millimeters, highly is 3～5 millimeters (Fig. 2).

One netted (4) (being the equatorial plane) established at the horizontal center of spheroid, simultaneously, establish one vertical netted (4) along the vertical center line (south poles) of spheroid, two netted garden faces intersect vertically, thereby it is together empty that spheroid is divided into four isometric(al)s, level net and vertical web all are made up of mutual decussate barrier (5), and the spacing of its netted barrier (5) is 3～8 millimeters.The width of netted barrier self is 2～3 millimeters, and 2～3 millimeters of thickness are same, 30～50 millimeters two barriers of whenever being separated by, and also being provided with width in the vertical direction of net is 1.5 millimeters, height is at 3～5 millimeters stiffening web (3).Spheroid is divided into four netted isometric(al) spaces by level and vertical barrier, and each space is provided with a multiaspect hollow ball (0), and this ball system adopts the employed a kind of filler of present sewage disposal technology.

Whole spheroid divides two halves processing, make with injection moulding, two hemisphere, the string center of establishing a groove (6) and another half garden face in the center of the string of barrier one and half garden faces is established a forked plate (7) and is plugged (Fig. 3), after two hemisphere merge, becomes as a whole hollow ball, outer garden seam crossing along hemisphere is provided with 6～8 place's welds (8) fixedly connected (Fig. 4) again, all spheroid and barrier are all made with poly-second (third) alkene material, are convenient to single injection-molded.

This utility model is to be provided with bead in the big ball, form dynamic stereo structure, it is also very even that filler is distributed when static, big ball is promoted by oxygenation, bead forms especially as the sun in big ball, the earth, the revolution of the moon, the composite motion state of rotation, so this dynamic solid spherical suspending filling material is than prior art, mainly be to have improved the overall gas degree that is evenly distributed, make sewage treating efficiency become good, simultaneously, the stiffening web that is provided with, except that improving the spheroid self rigidity, also help the free movement of the intravital multiaspect hollow ball of hollow, be unlikely to destroy at warp, formed microorganism exchange membrane on parallel net surface and the barrier keeps microbiological treatment quantity and is disturbed less.

Claims

1, the spherical gauze packing of forming with poly-second (third) alkene material, it is characterized in that: spherical surface is made up of warp, parallel (2), netted spheroid is provided with the equator and along two netted (4) of vertical axis in inside, this netted is made of many barriers (5), two netted of intersecting vertically, hollow ball is divided into spaces such as four, a multiaspect hollow ball (0) is installed in each mesh space, constitute a dynamic solid spherical suspending filling material.

2, according to the dynamic solid spherical suspending filling material of claim 1, it is characterized in that: through at a distance of the 30-50 millimeter two of, parallel, be provided with stiffening web (3) at its spheroid inner face, the height of stiffening web is the 3-5 millimeter, and width is 1.5 millimeters.

3, according to the dynamic solid floating stuffing of claim 1, it is characterized in that: netted of constituting by level and vertical barrier in its spheroid inside, at two barriers at a distance of the 30-50 millimeter, every barrier two sides all is provided with stiffening web equally, highly be the 3-5 millimeter, width is 1.5 millimeters.

4, according to the dynamic solid spherical suspending filling material of claim 1, it is characterized in that: the warp of netted sphere, the voidage of parallel are controlled at the 25-100 square millimeter.
