Description

Technical Field

[0001] The utility model relates to the technical field of suspended ball fillers, in particular to a highly efficient rotary suspended ball filler with good aeration effect. Background Art

[0002] With the development of an environmentally friendly society, sewage treatment is receiving increasing attention. Generally, in the sewage or wastewater treatment process, fillers are filled in a biofilm reaction tank. The fillers are suspended and immersed in water, providing a place for microorganisms to grow and attach. The aerated and oxygenated wastewater flows through the fillers at a certain flow rate, and is purified by the action of microorganisms.

[0003] A Chinese authorized patent document, publication number CN209065516U, discloses a honeycomb-shaped suspended ball packing, comprising a main body composed of a first hemispherical shell, a second hemispherical shell, and an annular fastening hoop. The first and second hemispherical shells are fixed to the top and bottom of the annular fastening hoop, respectively. The first and second hemispherical shells are each provided with a plurality of through-holes extending along the same axis. The holes are arranged in a regular hexagonal structure composed of six fixing rods. Fixing blocks are fixed to the top and bottom of the outer sides of the first and second hemispherical shells. The honeycomb-shaped suspended ball packing of the utility model comprises rotatable blades formed by a rotating shaft, semicircular support bars, and connecting rods. This facilitates the attachment of microorganisms and the flow of organic matter or nutrients in wastewater between the blades, unaffected by the water flow, effectively improving oxygen utilization. The honeycomb-shaped suspended ball packing has a large specific surface area, which increases the contact area between the suspended balls and microorganisms, reduces production costs, and improves wastewater treatment efficiency.

[0004] The above-mentioned prior art does not strengthen, improve, design and protect the blade structure, resulting in poor overall rotation effect of the suspended ball filler, which makes it difficult for the biological layer on the internal sponge block to fall off and the sewage purification efficiency is low. Therefore, it is necessary to develop a suspended ball filler with high-efficiency rotating aeration effect. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1-5The utility model provides an embodiment: a suspended ball filler with a high-efficiency rotating aeration effect, comprising an upper hemisphere 2 and a lower hemisphere 6, the outer surface of the upper hemisphere 2 is provided with a first fixing chuck 4, the outer surface of the lower hemisphere 6 is provided with a second fixing chuck 5, the first fixing chuck 4 and the second fixing chuck 5 are fixedly connected by a hexagonal screw 3, the upper end surface of the first fixing chuck 4 is fixedly connected with a blade structure 7 by a screw, a bending portion 9 is provided at the middle part of the blade structure 7, the upper end surface of the blade structure 7 is coated with a first smooth coating structure 10, the lower end surface of the blade structure 7 is coated with a second smooth coating structure 12, and the surface of the blade structure 7 is provided with a streamlined curved surface structure 11.

[0026] Furthermore, the surfaces of the upper hemisphere 2 and the lower hemisphere 6 are both provided with honeycomb slot structures 1 .

[0027] Furthermore, a first thread slot 13 is provided on the surface of the blade structure 7 , and a second thread slot 8 is provided on the surfaces of the first fixing chuck 4 and the second fixing chuck 5 .

[0028] Furthermore, a plurality of blade structures 7 are provided, and the installation position of the blade structure 7 is adjusted according to the position of the second threaded slot 8 .

[0029] Furthermore, the bending portion 9 is a bendable and deformable soft metal structure made of copper or aluminum.

[0030] Furthermore, microbial sponge block structures for aeration are placed inside the upper hemisphere 2 and the lower hemisphere 6 .

[0031] Working principle: When in use, several fixed suspended ball fillers in this embodiment are put into the aerated biological filter tank of the sewage treatment equipment. When the sewage passes through, the flow of water drives the blade structure 7 to rotate. Since the traditional suspended ball filler has a poor rotation effect during aeration, it is difficult for the biological layer on the sponge inside it to fall off. Therefore, the blade structure 7 can be quickly installed and fixed by adopting a chuck with a screw hole alignment structure, which has the advantages of convenient and fast installation and disassembly. At the same time, the number and installation position of the blades can be flexibly adjusted according to the position of the screw holes on the surface of the fixed chuck, which is convenient for the blades to rotate efficiently. A bending part 9 is provided in the middle part of the blade structure 7. The bending part 9 is a soft metal structure made of copper or aluminum that can be bent and deformed. It is bent by manual bending. Part 9 adjusts the inclination angle of the blade to optimize the rotation effect of the blade. The upper end surface of the blade structure 7 is coated with a first smooth coating structure 10, and the lower end surface of the blade structure 7 is coated with a second smooth coating structure 12. By providing a smooth coating structure on the outer surfaces of both sides of the blade structure 7, the friction between the blade structure 7 and the water flow during rotation can be effectively reduced, thereby accelerating the rotation speed. The surface of the blade structure 7 is provided with a streamlined curved surface structure 11. By designing a streamlined blade shape to reduce resistance, the rotation effect of the blade structure 7 is accelerated. By providing multifunctional design protection for the blades, the suspended ball filler can rotate better during aeration, and the biological layer on the internal sponge block can be quickly detached, which has the advantages of good degradation effect and high sewage purification efficiency.
