Abstract

The utility model relates to a hollow tooth-profile fluidized filler. A main body of the hollow tooth-profile fluidized filler is in a hollow shape; gear teeth are uniformly arranged around the tooth-shaped center which is taken as a center of a circle; the integral shape is in a hollow gear shape. The main body can be sufficiently driven in water to rotate and flow in various angles and directions under the functions that water flow and air bubble play the multiple direction force actions for the gear teeth, thereby, the mass transfer among water, gas, microbes, and fluidization filler of the water, gas and microbes is enhanced; the inner and outer surfaces of the main body and the gear teeth are uniformly distributed with peak valleys, the adsorption capacity of which is strong, which is convenient for the attachment of the microbes, the hang of films, the growth on a bed, falling off and replacement; materials which is used in definite formulation can ensure the specific gravity of the hollow tooth-profile fluidized filler close to 1.0; the aim of the regulation of specific surface areas can be obtained by the method that the numbers of the gear teeth or the dimensional proportion of addendum circle and root circle diameter of the gear teeth is regulated according to different water quality requirements. The structural strength design of the utility model is reasonable, the utility model is difficult to break during the transporting and using periods, and the transporting cost is reduced. When used, the utility model can be directly put into a biological reacting pool which is needless to empty when the utility model is replaced, and the use is convenient.

Description

Hollow tooth-shape fluidized filling

Technical field

The utility model belongs to water treatment biological carrier filler field, relates to a kind of hollow tooth-shape fluidized filling.

Background technology

Bio-carrier is applied in water and the wastewater biological embrane method water technology, during use, carrier filler is invested in biological reaction tank after, can be based on the coenosis of microorganism attached on the carrier, with the pollutent in the water is nutrition, reaches the purpose of purifying waste water.The prior biological carrier filler is generally sheet shape, square, spheroidal, cylindric etc., it is unreasonable that this class carrier exists Structural Strength Design, adsorptive power is undesirable, broken easily, production efficiency is low, the high deficiency of trucking costs has influenced the widespread use of bio-carrier to a certain extent.

The utility model content

It is a kind of simple in structure that the purpose of this utility model is to provide, and structural strength is reasonable, the hollow tooth-shape fluidized filling of high adsorption capacity.

The technical solution adopted in the utility model: a kind of hollow tooth-shape fluidized filling, its body are hollow shape, are that the center of circle evenly is provided with teeth with the profile of tooth center.

Be covered with peak valley on described body and the teeth surfaces externally and internally.

Described teeth axial length and wall thickness and the isometric uniform thickness of body, length is 20～200mm, and wall thickness is 0.5～1.5mm, and the teeth external diameter is 20～200mm.

Moulded open column shape gear shape, hollow triangle gear shape, the hollow arc gear wheel shape of being of described body and teeth.

Described teeth are at least 3, and the cross section of each teeth is open column shape tooth, lance tooth, arc tooth or irregular odontoid.

Described body is a hollow shape, teeth and polygonal body property at parts of edges and corners rounding off.

The tip diameter of described teeth is 20～200mm, and root diameter is 10～180mm.

The positive beneficial effect that the utility model had:

1. the moulded hollow wheel gear shape that is, by the effect of current and bubble to the multi-faceted power of teeth, can fully drive body and in water, realize the rotation of multiple angles, direction and flow, thereby strengthen between water, gas, the microorganism three and the mass transfer on fluidized packing material;

2. the surfaces externally and internally of body and teeth all is covered with peak valley, and high adsorption capacity is rational in infrastructure, is convenient to microorganic adhesion, biofilm, implantation growth and the renewal that comes off;

3. Structural Strength Design is reasonable, is difficult for fragmentation in transportation and the use, and trucking costs reduces;

4. can directly throw in when using in the biological reaction tank, also need not the emptying reaction tank during replacing, easy to use;

5. select the material of certain prescription for use, the proportion that guarantees product can by quantity that increases teeth or point circle, the root diameter dimension scale of adjusting teeth, reach the purpose of adjusting specific surface area according to the different quality requirement near 1.0;

6. the utility model is simple in structure, and production efficiency improves, and is economical and practical, has wide range of applications.

Embodiment

Embodiment 1

Consult Fig. 1, Fig. 2, shown in Figure 3, a kind of hollow tooth-shape fluidized filling comprises body 1, teeth 2 etc.; Its body 1 is a hollow shape, with the profile of tooth center is the center of circle, be evenly distributed with teeth 2 on the body 1, teeth 2 quantity are at least 3, are preferably 3-16, and the tip diameter of teeth 2 is 20～200mm, root diameter is 10～180mm, according to the different quality requirement,, reach the purpose of adjusting specific surface area by quantity that increases teeth 2 or point circle, the root diameter dimension scale of adjusting teeth 2; Teeth 2 axial lengths and wall thickness and body 1 isometric uniform thickness, length is 20～200mm, the shape that can be cut into pieces according to actual needs, wall thickness is 0.5～1.5mm, and teeth 2 external diameters are 20～200mm, and the cross section of each teeth 2 is the open column shape odontoid; Described body 1 adopts moulds by automatic molder extrusion molding, stretching, typing moulding with teeth 2, mouldedly is the open column shape gear shape, and is covered with peak valley 3 on the surfaces externally and internally, the renewal of being convenient to microorganic adhesion, growing and coming off.

Embodiment 2

Consult Fig. 4, Fig. 5, shown in Figure 6, described body 1 and teeth 2 are moulded also can be the hollow triangle gear shape, the cross section of each teeth 2 odontoid triangular in shape.All the other structures are with embodiment 1.
