Description

Technical Field

[0001] This utility model relates to the field of steel structure tanks for integrated sewage treatment ponds, and more specifically, to a steel structure tank for integrated sewage treatment ponds. Background Technology

[0002] Wastewater treatment ponds are facilities for treating domestic sewage. They primarily remove suspended solids, organic matter, and pathogens from water through physical, chemical, and biological methods, thereby purifying the water. Wastewater treatment ponds typically include sedimentation, filtration, and disinfection zones. Through these processes, impurities in the sewage are removed, and water quality is improved. Buried wastewater treatment ponds are products that combine septic tank treatment and treatment functions. They are characterized by high compressive strength and mainly include sedimentation and treatment zones. They can effectively treat domestic sewage and prevent pipe blockage. This type of wastewater treatment pond is usually designed to be buried underground to reduce environmental impact and extend its service life. Wastewater treatment ponds play an important role in environmental protection, effectively reducing sewage pollution and protecting water resources and the ecological environment. Through proper design and maintenance, wastewater treatment ponds can ensure that the treated water meets discharge standards, thereby protecting the natural environment and human health. With large wastewater treatment volumes, the size of wastewater treatment ponds also increases. Generally, wastewater treatment ponds are mainly constructed with reinforced concrete structures, which have long construction cycles and high construction costs. However, some existing steel structure ponds are not easy to assemble and have low efficiency. The welding connection method between steel structures affects the later disassembly and reuse. Therefore, in order to address the above problems, a steel structure pond for large-scale integrated wastewater treatment ponds is proposed.

[0003] In the prior art, such as the authorized announcement number CN221972642U, this utility model discloses a steel structure tank body for a large integrated sewage treatment tank, including a steel frame, supporting steel, connecting holes, bolts, through holes, reinforcing bars, thin steel sheets, a circular base and a plug groove. This utility model is reasonably designed. Multiple steel frames are distributed in a ring on the top area of ​​the circular base, and the steel frames are connected together from top to bottom by multiple reinforcing bars. At the same time, the bottom end of each steel frame is inserted into the corresponding plug groove on the circular base, which can form a weld-free steel structure tank body skeleton. Each through hole on the steel frame is in close contact with the reinforcing bar, which avoids the steel structure tank body skeleton from swaying. Utilizing the flexibility of the thin steel sheet, one end of the bolt on the thin steel sheet is inserted into the corresponding connecting hole and the nut on the bolt is tightened, which is conducive to the convenient and quick completion of the installation of the inner wall of the tank body. It solves the problem of cumbersome and inefficient assembly of existing steel structure tank bodies, effectively shortens the construction period of sewage treatment tanks and puts them into use.

[0004] In the aforementioned patent, the interlocking slots are used for connection, and adjacent panels are fixed with bolts and nuts. This results in low assembly efficiency, complex installation of the overall steel structure pool, and inconvenience in use. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an integrated steel structure tank for sewage treatment, which adopts an arc-shaped splicing plate structure and is installed by interlocking with the circular base plate. The adjacent arc-shaped splicing plates fit together concave and convex, and are locked and fixed externally by arc-shaped clamp strips. This eliminates the need for a large number of bolts and nuts, making installation convenient and efficient.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An integrated sewage treatment tank with a steel structure includes a circular base plate. The circular base plate is constructed of a convex circular steel plate. Arc-shaped splicing clamping plates are snapped onto the inner surface of the outer end of the circular base plate. These arc-shaped splicing clamping plates are evenly distributed and snapped onto a ring of the circular base plate. The outer surfaces of the arc-shaped splicing clamping plates are pressed and fixed together. An arc-shaped protrusion is provided on the lower surface of each arc-shaped splicing clamping plate. The outer surface of the arc-shaped protrusion is snapped onto the inner surface of the circular base plate. A raised strip is provided at one end of the side of each arc-shaped splicing clamping plate, and a raised strip is provided at the other end of the side of each arc-shaped splicing clamping plate. The curved splicing plates are provided with recessed grooves, and the protruding strips of the curved splicing plates are engaged with the inner surfaces of the recessed grooves of adjacent curved splicing plates. Curved clamping strips are fixedly installed on the outer surfaces of the curved splicing plates, with both sides of the clamping strips clamping the outer surfaces of the curved splicing plates. The outer ends of the clamping strips are locked and fixed by bolts and nuts. The curved splicing plate structure is used, and it is engaged with the circular base plate. The adjacent curved splicing plates fit together perfectly, and are locked and fixed externally by the curved clamping strips. This eliminates the need for a large number of bolts and nuts, making installation convenient and efficient.

[0008] Furthermore, the arc-shaped clamp strip is provided with raised plates on both the left and right sides, and the raised plates are provided with through holes, and the bolts are inserted into the inner surface of the through holes.

[0009] Furthermore, an annular groove is provided on the outer surface of the circular base plate, and the outer surface of the lower arc-shaped protrusion of the arc-shaped splicing plate is engaged with the inner surface of the annular groove.

[0010] Furthermore, the raised strips and recessed grooves of the arc-shaped splicing plate fit together.

[0011] Furthermore, the outer surface of the arc-shaped splicing plate is treated to be smooth and flat.

[0012] Furthermore, the upper and lower sets of arc-shaped clamp strips are locked and fixed to the arc-shaped splicing clamp plate components.

[0013] Furthermore, both the circular base plate and the arc-shaped splicing plate are made of stainless steel.

[0014] Compared with existing technologies, the advantages of this utility model are:

The adjacent arc-shaped splicing plate fits together, and is locked and fixed by the arc-shaped clamp strip. It does not require a lot of bolts and nuts, making it easy to install and efficient.
