Description

Technical Field

[0001] This invention relates to the field of water treatment tank technology, and in particular to a square all-stainless steel mechanically stirred clarification tank structure. Background Technology

[0002] Currently, mechanically stirred clarifying tanks are generally reinforced concrete circular tanks or steel-structured circular tanks.

[0003] This type of pool has many drawbacks:

[0004] 1. Concrete water tanks are heavy, requiring higher foundation bearing capacity;

[0005] 2. Reinforced concrete water tanks need to be cast in place, which is greatly affected by the climate and has a long construction period;

[0006] 3. Although circular pools have a large volume, their building area utilization rate is low, and if expansion is considered in the later stages of operation, the difficulty will increase.

[0007] 4. Precast concrete components such as inclined bracing beams and umbrella panels inside the pool often face installation difficulties due to construction errors;

[0008] 5. Reinforced concrete pools are difficult to renovate, expand, or relocate, and are costly and cannot be recycled.

[0009] Therefore, a square, all-stainless steel mechanically stirred clarification tank structure needs to be designed to solve the above problems. Summary of the Invention

[0010] The purpose of this invention is to provide a square, all-stainless steel mechanically stirred clarification tank structure to solve the above-mentioned problems.

[0011] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a square all-stainless steel mechanically stirred clarification tank structure, comprising:

[0012] A steel frame is provided, a second steel frame is provided on top of the first steel frame, a third steel frame is provided on top of the second steel frame, a fourth steel frame is provided on top of the third steel frame, a water tank base is provided below the first steel frame, and ten load-bearing square steel pipes are fixedly installed on the top of the water tank base. The load-bearing square steel pipes are fixedly connected to the first, second, third and fourth steel frames.

[0013] A further provision of the present invention is that the first-layer steel frame adopts a radially arranged steel beam system, the radially arranged steel beam system includes a bottom plate beam, a circumferential steel beam and a main beam, and the circumferential steel beam is welded to the main beam.

[0014] A further feature of the present invention is that a mud collection trough is provided at the center of the radially arranged steel beam system, and four square steel pipe columns and eight square steel pipe columns are provided at the bottom of the bottom plate beam.

[0015] A further configuration of the present invention is as follows: the eight square steel pipe columns are evenly arranged along the inner circle, and the four square steel pipe columns are located at the intersection of the diagonal of the square and the inscribed circle.

[0016] A further feature of the present invention is that the two-story steel frame adopts a peripheral horizontal truss beam tie system.

[0017] A further feature of the present invention is that the three-layer steel frame adopts a structural form combining horizontal truss beams and corner supports, and a vertical diagonal brace is added in the middle.

[0018] A further feature of the present invention is that the four-layer steel frame adopts a combination system of steel platform and tie rod.

[0019] A further feature of the present invention is that a ladder is fixedly installed on the base of the pool.

[0020] A further feature of the present invention is that guardrails are fixedly installed on both the ladder and the four-layer steel frame.

[0021] The beneficial effects of this invention are:

[0022] 1. A layered steel frame design is adopted, with each layer using different structural forms according to functional requirements, forming an efficient spatial stress-bearing system. The radial steel beam system of the first-floor steel frame, combined with the square steel pipe columns at the bottom, evenly distributes the load to the foundation, reducing the problem of local stress concentration compared to the traditional circular water tank's concentrated stress mode. The peripheral horizontal truss beam tie system of the second floor effectively enhances lateral stiffness without affecting the internal reaction chamber space. The horizontal truss beams of the third floor, combined with corner supports and central vertical diagonal braces, improve the overall torsional resistance and planar stability of the structure. External stability; the four-layer steel platform and tie rod combination system enhances the overall structure of the pool top, effectively resisting the load of the top equipment and the horizontal forces such as external wind and seismic forces, ensuring the stable operation of the pool under complex working conditions. The pool structure is constructed entirely of stainless steel, which has stronger corrosion resistance compared to reinforced concrete and steel structure circular pools. Stainless steel can effectively resist the erosion of acidic and alkaline substances and microorganisms during water treatment, avoiding problems such as concrete cracking and steel corrosion, greatly extending the service life of the pool and reducing the maintenance and reconstruction costs caused by structural damage.

[0023] 2. The clarification tank adopts a modular design. All components, such as the steel frame and load-bearing square steel pipes, are prefabricated in the factory, ensuring controllable quality and precision. During on-site construction, only component hoisting and connection are required. Compared with the traditional cast-in-place reinforced concrete water tank process, it eliminates the need for cumbersome procedures such as formwork construction, rebar tying, and long-term concrete curing, which can shorten the construction cycle by 40%-50%. It is not limited by climatic conditions (such as high temperature, low temperature, and rainfall), effectively ensuring the project schedule. The standardized components and connection methods reduce the technical difficulty and complexity of on-site construction, reduce reliance on professional construction personnel, reduce quality risks during construction, and also reduce noise, dust, and other pollution at the construction site, achieving green construction.

[0024] 3. Unlike traditional circular pools, square structures allow for full utilization of corner spaces, increasing building area utilization by 10%-20% compared to circular pools. In situations of limited land resources, this allows for a larger effective volume within the same footprint, or reduces land use and acquisition costs while meeting the same water treatment requirements. The regularity of the square structure also makes internal space layout more flexible, allowing for easy division of different functional areas such as reaction zones, sedimentation zones, and sludge collection zones according to water treatment process needs, optimizing water flow paths and improving water treatment efficiency. Furthermore, it facilitates future upgrades and modifications to the pool's internal equipment and facilities.

[0025] 4. The all-stainless steel structure has a smooth surface, making it less prone to the adhesion of sludge and microorganisms, thus reducing the workload and frequency of daily cleaning and maintenance. The modular design makes the installation and disassembly of internal components (such as diagonal bracing beams and umbrella panels) more convenient. If damage occurs or replacement is needed, the damaged components can be directly disassembled for repair or replacement, avoiding the problems of difficult installation and inconvenient maintenance caused by construction errors in traditional precast concrete components. This significantly reduces maintenance costs and time. Due to the high durability of stainless steel and the stability of the structural design, the water tank does not require frequent structural reinforcement, anti-corrosion treatment, or other maintenance work during long-term operation, reducing maintenance expenses. At the same time, efficient space utilization and reasonable process layout help improve water treatment efficiency, reduce energy consumption, and further reduce operating costs.

[0026] 5. When the water tank needs to be renovated, expanded, relocated, or scrapped, the all-stainless steel components can be disassembled and recycled, realizing the reuse of materials, reducing the generation of construction waste, and conforming to the concept of green building and sustainable development. Compared with the non-recyclable reinforced concrete tank, it has significant environmental advantages and economic benefits. The modular structure design and detachable connection method make it possible to expand or renovate the water tank in the later stage of operation by adding standardized steel frame modules and adjusting the internal layout, without the need for large-scale demolition and reconstruction of the original structure. This reduces the cost of renovation and expansion and the difficulty of construction, and improves the adaptability of the water tank to future process adjustments and capacity increases.

[0027] 6. The standardized production of prefabricated components in the factory can strictly control the dimensional accuracy and quality of the components, reduce on-site construction errors, and significantly reduce construction errors from a large range to within ±5mm compared with traditional concrete water tank construction, thereby improving the overall quality of the project and ensuring structural safety and reliability.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection", and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0039] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] See Figures 1-8 This invention provides a square, all-stainless steel mechanically stirred clarification tank structure, comprising:

[0041] A steel frame 1 is provided, a second steel frame 2 is provided on top of the first steel frame 1, a third steel frame 3 is provided on top of the second steel frame 2, a fourth steel frame 4 is provided on top of the third steel frame 3, a water tank base 5 is provided below the first steel frame 1, and ten load-bearing square steel pipes 6 are fixedly installed on the top of the water tank base 5. The load-bearing square steel pipes 6 are fixedly connected to the first steel frame 1, the second steel frame 2, the third steel frame 3 and the fourth steel frame 4.

[0042] The above-described structure, employing standardized and modular stainless steel square water tank units, utilizes a construction mode of factory prefabrication and rapid on-site assembly, significantly improving construction efficiency and shortening the construction period by approximately 40%-50%. The modular design fully considers structural scalability, enabling convenient future expansion through standardized connection nodes and detachable structures, meeting the needs of process adjustments or capacity increases. The modular units utilize high-performance stainless steel materials, combined with an optimized structural system, ensuring structural durability and reliability. The innovative modular design achieves controllable construction quality; through standardized factory production, on-site construction errors are controlled within ±5mm, significantly improving project quality. The modular system offers good economic benefits; through standardized production and large-scale construction, overall costs can be reduced by 15%-20%, while simultaneously reducing on-site construction waste and achieving green construction. This invention, through its innovative modular structural system, solves the technical challenges of traditional reinforced concrete mechanical mixing clarification tanks, such as long construction cycles, large installation errors of prefabricated components within the tank, difficulties in modification and expansion, challenges in quality control, and difficulties in recycling and reuse, demonstrating significant technological advancement and practical value.

[0043] Specifically, the first-floor steel frame 1 adopts a radially arranged steel beam system, which includes a bottom plate beam, circumferential steel beams and main beams. The circumferential steel beams are welded to the main beams. A mud collection trough 7 is set in the center of the radially arranged steel beam system. Four square steel pipe columns 1 8 and eight square steel pipe columns 2 9 are set at the bottom of the bottom plate beam. The eight square steel pipe columns 2 9 are evenly arranged along the inner circle, and the four square steel pipe columns 1 8 are located at the intersection of the diagonal of the square and the inscribed circle.

[0044] The above structure features corner bracing to enhance overall stability, and the circumferential ring beams of each layer are welded to the main beam to form a spatial overall force-bearing system.

[0045] Specifically, the second-floor steel frame 2 adopts a peripheral horizontal truss beam tie system.

[0046] Due to the process requirements for setting up a reaction chamber, a conventional through-bracing system could not be used. Therefore, the second-floor steel frame 2 adopts a peripheral horizontal truss beam bracing system, which not only meets the internal space requirements but also effectively enhances the lateral stiffness of the structure and ensures the overall stability of the structure.

[0047] Specifically, the three-story steel frame 3 adopts a structural form that combines horizontal truss beams with corner supports, and adds vertical diagonal braces in the middle.

[0048] Through the above structure, the three-layer steel frame 3, combined with the requirements of the inclined tube layer, adopts a structural form that combines horizontal truss beams and corner supports. While providing necessary internal constraints, it also provides reliable support for the inclined tube system. In addition, by adding vertical diagonal braces in the middle of the structure, the out-of-plane calculation length of the horizontal truss beams is effectively reduced, thereby improving the overall stability of the structure.

[0049] Specifically, the four-story steel frame adopts a combination system of steel platform and tie rod.

[0050] Through the above structure, the four-layer steel frame 4 adopts a combination system of steel platform and tie rod, which effectively enhances the integrity and restraint of the pool roof structure.

[0051] Specifically, a ladder 10 is fixedly installed on the base 5 of the pool, and guardrails 11 are fixedly installed on both the ladder 10 and the four-layer steel frame 4. It should be noted that this is to facilitate climbing and ensure safety.

[0052] This structural system significantly improves structural stress performance through the rational design of internal and top constraint systems. Compared with traditional concrete cantilever structures, this steel structure system has advantages such as clear stress distribution, well-defined force transmission paths, and reasonable structural stiffness distribution, fully demonstrating the adaptability and superiority of steel structures under complex technological conditions.

[0053] Working principle:

[0054] The ten load-bearing square steel pipes 6 at the top of the base 5 of the water tank serve as the main support structure, vertically penetrating and fixing one layer of steel frame 1 to four layers of steel frame 4, forming a vertical load-bearing system from bottom to top. The load-bearing square steel pipes 6 are made of high-strength stainless steel and are rigidly connected to each layer of steel frame by welding or bolting, so as to evenly transfer the vertical loads such as water load and structural self-weight in the water tank to the foundation, avoiding excessive local stress.

[0055] The first-layer steel frame 1 adopts a radial steel beam system. The circumferential steel beams are welded to the main beam to form a mesh structure. A sludge collection trough 7 is set in the center to collect settled sludge. The four square steel pipe columns 1 8 and eight square steel pipe columns 2 9 at the bottom of the bottom plate beam form the bottom support matrix. The square steel pipe columns 2 9 are evenly arranged along the inner circle, and the square steel pipe columns 1 8 are located at the intersection of the square diagonal and the inscribed circle. The load is distributed through multi-point support to enhance the stability of the bottom structure.

[0056] Because a reaction chamber needs to be set up inside the second-floor steel frame 2, a peripheral horizontal truss beam tie system is adopted. The truss beams are welded to the steel frame through node plates. Utilizing the spatial force characteristics of the truss, the second-floor structure is provided with lateral stiffness without affecting the space of the reaction chamber, resisting the lateral forces generated by horizontal wind loads, seismic forces, or water flow impact.

[0057] The three-layer steel frame 3 combines the requirements of the inclined tube layer in the process and adopts the form of horizontal truss beams and corner supports. Vertical diagonal members are added in the middle. The horizontal truss beams support the weight of the inclined tube layer, and the corner supports and vertical diagonal members form a triangular stable structure, which reduces the out-of-plane deformation of the truss beams and enhances the overall torsional resistance.

[0058] The four-layer steel frame 4 uses a combination system of steel platform and tie rods. The steel platform bears the load of the top equipment, and the tie rods, such as steel wire ropes or steel tie rods, connect the steel platform and the lower frame to form tension constraints, improve the overall integrity of the pool roof structure, and prevent the top from deforming too much due to local loads.

[0059] All components, including the steel frames, load-bearing square steel pipes 6, and square steel pipe columns, are prefabricated in the factory. Standardized processing ensures dimensional accuracy, with errors controlled within ±5mm. During on-site construction, the pool base 5 is installed first, followed by the sequential hoisting of the first to fourth layers of steel frames. These are connected by the load-bearing square steel pipes 6 and secured using welding or high-strength bolts to form an integral structure. This modular construction method can shorten the construction period by 40%-50% and is unaffected by weather conditions, such as the curing period of concrete. The connection nodes of each layer of steel frames adopt a detachable structure, such as bolted connections. When expansion is needed, some nodes can be removed, and horizontal or vertical expansion can be achieved by adding standardized steel frame modules. For example, identical structural units can be added to one or more sides of the square pool and connected to the original frame via the load-bearing square steel pipes 6, ensuring the integrity of the expanded structure and solving the problem of the difficulty in expanding traditional circular pools.

[0060] The sludge collection trough 7 at the center of the first-layer steel frame 1 is connected to the sludge hopper at the bottom of the pool. The reacted sludge-water mixture settles under gravity, and the sludge is collected and discharged through the sludge collection trough 7, while the clear water flows upward into the subsequent treatment unit. The radial steel beam system provides a flat surface for the flow of sludge at the bottom of the pool, avoiding dead corners where sludge accumulates. The reaction chamber in the second-layer steel frame 2 is used to add chemicals and react with water to form flocs. The inclined tube layer supported by the third-layer steel frame 3 provides sedimentation space for the flocs. The inclination angle and spacing of the inclined tubes are optimized to improve sedimentation efficiency. Horizontal truss beams and corner supports ensure the stability of the inclined tube layer and prevent displacement of the inclined tubes due to water flow impact.

[0061] Made entirely of stainless steel, it is corrosion-resistant and has high strength. Compared with reinforced concrete structures, it can avoid problems such as concrete cracking and steel corrosion, thus extending the service life of the pool. The surface of stainless steel components is smooth, making it less prone to the adhesion of sludge and microorganisms, reducing maintenance costs. At the same time, stainless steel materials are recyclable and reusable. When the pool needs to be relocated or demolished, the components can be disassembled and recycled, reducing construction waste and costs.

[0062] The above provides a detailed description of the structure of a square, all-stainless steel mechanically stirred clarifier tank provided by the present invention. Specific embodiments have been used to illustrate the principles and implementation methods of the present invention. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
