Description

A chain-type packing installation device for sewage treatment equipment Technical Field

[0001] This invention relates to a packing material installation device for wastewater treatment equipment. Background Technology

[0002] With the intensification of industrialization and urbanization in my country, the wastewater treatment industry has received widespread attention and become an indispensable part of social development and progress. At the same time, the wastewater treatment industry is closely related to ecological environmental protection and is crucial for building a green China. After decades of development, the activated sludge process has become the preferred treatment process for urban wastewater treatment plants, and various process forms have emerged. However, in low-temperature environments, the activity of enzymes involved in biochemical reactions is inhibited, and the metabolic rate of microorganisms slows down, leading to reduced treatment efficiency and the risk of effluent exceeding standards. To address the poor treatment effect of the activated sludge process at low temperatures, researchers have proposed methods such as extending sludge age, adding functional bacterial agents, and adding biological packing materials. These methods have played a certain role in the actual operation of wastewater treatment plants. Among them, adding biological packing materials can provide attachment and growth sites for microorganisms, extend sludge age, and promote the interaction between microorganisms and packing materials, thereby improving the system's treatment efficiency. Therefore, various types of biological packing materials have been developed and widely used.

[0003] Currently, biological packing materials are added or installed in two ways: fluidized and fixed. Flow-type installations require strict control over the flow pattern and operation of the biological treatment tank and are prone to loss with the effluent, thus they are mostly used in laboratories or small-scale pilot plants. Fixed installations avoid the problems of uneven distribution and easy loss of packing materials, making them the preferred installation method for biological packing materials in wastewater treatment plants. However, biological packing materials require regular maintenance during operation and replacement after their service life expires. This not only increases the workload of operators but also increases the operation and maintenance costs of wastewater treatment plants. Currently, the installation, maintenance, and replacement of biological packing materials require the use of heavy machinery and a significant amount of manpower. Summary of the Invention

[0004] The present invention aims to solve the technical problem that the installation and replacement of biological packing materials in the current sewage treatment process requires the use of large machinery and consumes a lot of manpower, and provides a chain-type packing material installation device for sewage treatment equipment.

[0006] The outer shell 7 has a hollow middle section, in which multiple horizontal beams 19 are evenly arranged vertically. A rotating shaft 6 is horizontally arranged near the top of the hollow middle section of the outer shell 7. A sprocket 5 is fixed at each end of the rotating shaft 6. A chain 4 is wound around each sprocket 5. A handle 8 is arranged on the outside of the outer shell 7 and is fixed to the rotating shaft 6. A bearing is installed at the contact position between the rotating shaft 6 and the frame of the outer shell 7, and the rotating shaft 6 is connected to the outer shell 7 through the bearing. The two ends of the chain 4 are fixed to the first connecting block 9 and the second connecting block 10, respectively. The two first connecting blocks 9 are symmetrically fixed to the upper surface of the counterweight 14, and the two second connecting blocks 10 are symmetrically fixed to the upper surface of the mounting plate 15.

[0007] Two vertical third sliding shafts 11 are symmetrically fixed in the hollow middle part of the outer casing 7, and two vertical fourth sliding shafts 12 are also symmetrically fixed; two first sliding holes 18 are symmetrically provided on the mounting plate 15, and the two first sliding holes 18 are respectively fitted onto the two third sliding shafts 11 for sliding movement; two second sliding holes are symmetrically provided on the counterweight 14, and the two second sliding holes are respectively fitted onto the two fourth sliding shafts 12 for sliding movement;

[0008] Two bases 13 are symmetrically fixed at the bottom of the outer shell 1, and a limiting block 20 is fixed on the base 13. The limiting block 20 is located below the mounting plate 15 and is used to limit the lower part of the mounting plate 15.

[0009] The movable plate 1 is an L-shaped plate, which is composed of a vertical plate 1-2 and a horizontal plate 1-3 fixed vertically. A horizontal groove 1-1 is provided on the horizontal plate 1-3 for filling the filler. Two collars 16 are provided on the back of the vertical plate 1-2. A horizontal second sliding shaft 3 and two horizontal first sliding shafts 2 are fixed on the front of the mounting plate 15, with the second sliding shaft 3 located above the first sliding shafts 2. The two collars 16 are respectively fitted onto the two first sliding shafts 2 and are slidably connected. The top of the vertical plate 1-2 is fitted onto the second sliding shaft 3 and is slidably connected. Four fixing components 17 are evenly arranged on the outer side of the outer shell 7.
