Description

Technical Field

[0001] This application relates to the field of prefabricated water tank technology, specifically to a multi-stage baffle prefabricated water tank. Background Technology

[0002] With the acceleration of urbanization and the enhancement of environmental awareness, wastewater treatment technology is receiving increasing attention. Traditional wastewater treatment ponds are usually constructed using on-site concrete casting, which suffers from problems such as long construction cycles, high costs, and difficult maintenance. To solve these problems, prefabricated water tanks have emerged on the market. These tanks adopt a modular design, using prefabricated modular components in a factory and assembled on-site, which can improve construction efficiency and shorten the construction cycle.

[0003] In wastewater treatment, to increase the contact time between wastewater and the treatment medium and enhance the treatment effect, it is usually necessary to divide the prefabricated water tank for different treatment processes. However, during water filling, the large liquid level difference on both sides of the partition can easily cause significant pressure impact on the partition, leading to deformation. In severe cases, this can cause internal partition failure and production accidents, affecting the overall operation of the wastewater treatment plant. Utility Model Content

[0004] The purpose of this application is to provide a multi-stage baffle assembled water tank to solve the problem of baffle deformation caused by large pressure impact due to liquid level difference during water injection.

[0005] The technical solution adopted by this application to solve its technical problem is:

[0006] A multi-stage baffled prefabricated water tank includes a tank bottom and a prefabricated tank body connected to the tank bottom. The prefabricated tank body includes an outer tank wall, an inner tank wall, and baffles. The inner tank wall is located inside the outer tank wall, and a plurality of baffles are arranged between the outer tank wall and the inner tank wall to form a plurality of processing chambers. A connecting pipe is connected between any two adjacent processing chambers, and a control device is provided on the connecting pipe. The control device can control the flow between adjacent processing chambers.

[0007] Furthermore, the control device includes at least one valve, and the valves on all connecting pipes can be linked together or controlled independently.

[0008] Furthermore, the height between the connecting pipe and the bottom of the pool is 0.3 to 1.5 m.

[0009] Furthermore, the bottom of the pool is a reinforced concrete structure, and an installation base groove is provided at the top of the pool bottom directly opposite the prefabricated pool body. Several height-adjustable anchor supports are fixed in the installation base groove, and the bottom of the prefabricated pool body is supported on the anchor supports.

[0010] Furthermore, the anchoring support includes an anchoring plate pre-embedded in the bottom of the pool, a support plate disposed above the anchoring plate, and a height-adjusting support connecting the anchoring plate and the support plate, with the bottom of the prefabricated pool body supported on the support plate.

[0011] Furthermore, the height adjustment support includes a vertically arranged adjusting screw and two adjusting nuts threadedly connected to the adjusting screw. The support plate is provided with a first through hole, through which the adjusting screw passes, and the two adjusting nuts are respectively arranged on both sides of the support plate. The lower end of the adjusting screw is fixedly connected to the anchor plate.

[0012] Furthermore, both the outer pool wall and the inner pool wall include a plurality of arc-shaped pool wall panels arranged in a circle, and adjacent arc-shaped pool wall panels are connected by a socket joint.

Unless otherwise specified, the above-mentioned orientational descriptions can be flexibly set in actual application, provided that the relative positional relationships shown in the accompanying drawings are satisfied.

[0050] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0051] See Figure 1 This application provides a multi-stage baffled prefabricated water tank, including a tank bottom 1 and a prefabricated tank body 3 connected to the tank bottom 1. The prefabricated tank body 3 includes an outer tank wall 31, an inner tank wall 32 and partitions 33. The inner tank wall 32 is located inside the outer tank wall 31, and a plurality of partitions 33 are arranged between the outer tank wall 31 and the inner tank wall 32, forming a plurality of processing chambers 34. A connecting pipe 35 is connected between any two adjacent processing chambers 34, and a control device is provided on the connecting pipe 35. The control device can control the flow between adjacent processing chambers 34.

[0052] Specifically, the bottom of the tank 1 is a horizontally arranged circular structure, and a prefabricated tank body 3 is connected to the bottom of the tank 1. The prefabricated tank body 3 includes an outer tank wall 31, an inner tank wall 32, and a partition 33; the outer tank wall 31 is cylindrical, and its bottom is supported on and connected to the bottom of the tank 1; the inner tank wall 32 is cylindrical, concentrically arranged inside the outer tank wall 31, and its bottom is supported on and connected to the bottom of the tank 1; the partition 33 connects the outer tank wall 31 and the inner tank wall 32, and its bottom is supported on and connected to the bottom of the tank 1. At least two partitions 33 may be included, and at least two partitions 33 are circumferentially arranged between the outer tank wall 31 and the inner tank wall 32 to form at least two treatment chambers 34 between the outer tank wall 31 and the inner tank wall 32. The number of partitions 33 can be set according to the discharge requirements of wastewater treatment, and is not specifically limited here. Any two adjacent processing chambers 34 are connected by a connecting pipe 35. A control device is installed on the connecting pipe 35 to control the opening and closing of the connecting pipe 35, thereby controlling the flow between the two adjacent processing chambers 34.

[0053] The multi-stage baffle-type prefabricated water tank provided in this application embodiment is used for sewage treatment. By setting a baffle 33 between the outer tank wall 31 and the inner tank wall 32, not only is the overall stability of the water tank improved, but multiple treatment chambers 34 are also formed between the outer tank wall 31 and the inner tank wall 32. By setting a connecting pipe 35 to connect two adjacent treatment chambers 34 and setting a control device on the connecting pipe 35, the control device can control the opening and closing of the connecting pipe 35, thereby controlling the flow between two adjacent treatment chambers 34. When the water tank is filled with water, the control device controls the opening of the connecting pipe 35, allowing sewage to flow between two adjacent treatment chambers 34. This balances the liquid level on both sides of the baffle 33, preventing a large liquid level difference on both sides of the baffle 33, and thus avoiding large pressure impacts on the baffle 33 that could cause deformation. After the water filling is completed, the control device controls the opening of the connecting pipe 35, allowing the sewage to be treated in multiple stages within the multiple treatment chambers 34.

[0054] In some embodiments, see Figure 1 The control device includes at least one valve 36, which controls the opening and closing of the connecting pipe 35. All valves 36 on the connecting pipe 35 can be interconnected or controlled independently. The valves 36 may include ball valves, gate valves, stop valves, and solenoid valves, and can also be manual or electric valves. For example, the control device includes two valves 36, and the connecting pipe 35 is generally U-shaped, located outside the outer pool wall 31. Both ends of the connecting pipe 35 are connected to the two valves 36, and the two valves 36 are connected to two adjacent treatment chambers 34. To further reduce the pressure impact on the baffle 33 during water injection, the connecting pipe 35 is located near the pool bottom 1; for example, the height between the connecting pipe 35 and the pool bottom 1 is 0.3–1.5 m.

[0055] In some embodiments, the pool bottom 1 is a reinforced concrete structure. Compared to a steel structure pool bottom, a reinforced concrete structure pool bottom is less expensive, easier to cast into various shapes and sizes, and also has good integrity, which is beneficial for earthquake resistance.

[0056] In some embodiments, see Figure 1 , Figure 2 An installation base groove 11 is provided at the top of the pool bottom 1, directly opposite the prefabricated pool body 3. Several height-adjustable anchor supports 2 are fixed in the installation base groove 11, and the bottom of the prefabricated pool body 3 is supported on the anchor supports 2.

[0057] The prefabricated pool body 3 can be constructed by factory prefabrication and on-site assembly. It requires a high level of accuracy for the pool bottom 1. If the level of the pool bottom 1 does not meet the requirements, leveling with shims or other measures is necessary. This application addresses this by setting an installation base trench 11 at the top of the pool bottom 1 and fixing height-adjustable anchor supports 2 within the installation base trench 11. When installing the prefabricated pool body 3 on-site, the height of the anchor supports 2 can be adjusted to level the installation reference surface, and then the prefabricated pool body 3 can be assembled and fixed to the anchor supports 2. This reduces the level of accuracy requirements on the concrete pool bottom 1. Even if the level of the pool bottom 1 does not meet the requirements, leveling with shims or other measures is unnecessary, thus improving the installation efficiency of the prefabricated pool.

[0058] In some embodiments, see Figure 2 , Figure 3 The anchor support 2 includes an anchor plate 21 embedded in the bottom of the pool 1, a support plate 22 set above the anchor plate 21, and a height adjustment support connecting the anchor plate 21 and the support plate 22. The bottom of the prefabricated pool body 3 is supported on the support plate 22.

[0059] Specifically, the anchor plate 21 is horizontally positioned at the bottom of the installation trench 11 and is fixedly connected to the pool bottom 1 by pre-embedding. To improve the firmness and reliability of the anchor plate 21 after pre-embedding, the anchor plate 21 is connected to the reinforcing bars in the pool bottom 1 via anchor steel strips 23. When pouring the pool bottom 1, during the reinforcing bar binding stage, the reinforcing bars, anchor steel strips 23, and anchor plate 21 are welded and fixed together before concrete pouring. The support plate 22 is horizontally positioned above the anchor plate 21 and is connected to the anchor plate 21 via height-adjustable supports. The height-adjustable supports not only support the support plate 22 but also adjust its height. The upper surface of the support plate 22 serves as the installation reference surface for supporting and fixing the bottom of the prefabricated pool body 3.

[0060] During construction, the height of the support plate 22 is first adjusted by adjusting the height of the support components. After all the support plates 22 are adjusted, the prefabricated pool body 3 is assembled on top of the support plates 22. After the prefabricated pool body 3 is assembled, the support plate 22 is connected to the bottom of the prefabricated pool body 3. Then, secondary grouting is carried out in the installation trench 11 to cover and conceal the anchor support 2 and the bottom of the prefabricated pool body 3. Then, anti-corrosion coating, waterproof coating, etc. are applied to achieve sealing and waterproofing between the bottom of the prefabricated pool body 3 and the pool bottom 1.

[0061] In some embodiments, see Figure 2 , Figure 3 , Figure 5 The height adjustment support includes a vertically arranged adjusting screw 24 and two adjusting nuts 25 threadedly connected to the adjusting screw 24. The support plate 22 is provided with a first through hole 221. The adjusting screw 24 passes through the first through hole 221, and the two adjusting nuts 25 are respectively arranged on both sides of the support plate 22. The lower end of the adjusting screw 24 is fixedly connected to the anchor plate 21.

[0062] Specifically, the adjusting screws 24 include four vertically arranged screws 24 in a rectangular or square configuration. Each adjusting screw 24 has two adjusting nuts 25 threaded onto it. The support plate 22 has four first through holes 221, which correspond one-to-one with the four adjusting screws 24. The adjusting screws 24 pass through their corresponding first through holes 221. The two adjusting nuts 25 on each adjusting screw 24 are located on the upper and lower sides of the support plate 22, respectively. The lower end of the adjusting screw 24 is fixedly connected to the anchor plate 21.

[0063] In use, the height of the support plate 22 can be adjusted by adjusting the position of the two adjusting nuts 25 on each adjusting screw 24. The level of the support plate 22 can be adjusted by cooperating the eight adjusting nuts 25. After the support plate 22 is adjusted, tighten the adjusting nuts 25 so that the adjusting nuts 25 abut against the surface of the support plate 22, thereby fixing the support plate 22 at the adjusted height.

[0064] The lower end of the adjusting screw 24 can be welded to the anchor plate 21 or threaded. See also the following in some embodiments: Figure 2 , Figure 3 , Figure 4 The anchor plate 21 is provided with a second through hole 211. The lower end of the adjusting screw 24 passes through the second through hole 211. The lower end of the adjusting screw 24 is threadedly connected to two fastening nuts 26, which are respectively located on both sides of the anchor plate 21.

[0065] Specifically, the anchor plate 21 has four second through holes 211, each corresponding to one of the four adjusting screws 24. The lower end of each adjusting screw 24 passes through its corresponding second through hole 211. Two fastening nuts 26 on each adjusting screw 24 are located on the upper and lower sides of the anchor plate 21, respectively. Tightening the fastening nuts 26 brings them into contact with the surface of the anchor plate 21, thus achieving a fixed connection between the adjusting screw 24 and the anchor plate 21.

[0066] The bottom of the prefabricated pool body 3 can be welded to the support plate 22, or it can be bolted to it. See also the following in some embodiments: Figure 2 , Figure 3 , Figure 5 The anchor support 2 also includes a vertically arranged fixing screw 27 and two fixing nuts 28 threadedly connected to the fixing screw 27. The support plate 22 is provided with a third through hole 222. The fixing screw 27 passes through the third through hole 222, and the two fixing nuts 28 are respectively arranged on both sides of the support plate 22. The fixing screw 27 is connected to the assembled pool body 3 through the connecting plate 29.

[0067] Specifically, the connecting plate 29 has an L-shaped structure, including a vertical part and a horizontal part. The horizontal part of the connecting plate 29 is provided with bolt holes for the fixing screw 27 to pass through. The vertical part of the connecting plate 29 can be fixedly connected to the lower end of the assembled pool body 3 by welding or bolts.

[0068] During installation, the vertical part of the connecting plate 29 is fixedly connected to the lower end of the assembled pool body 3. The bolt holes of the horizontal part of the connecting plate 29 are aligned with the third through hole 222. The fixing screw 27 is passed through the bolt hole of the third through hole 222 that is aligned with it. The two fixing nuts 28 are respectively connected to the upper and lower ends of the fixing screw 27. The two fixing nuts 28 are tightened and the support plate 22 is clamped to the horizontal part of the connecting plate 29 to achieve a fixed connection between the horizontal part of the connecting plate 29 and the support plate 22.

[0069] In some embodiments, see Figure 3 , Figure 5 Both the first through hole 221 and the third through hole 222 are oblong holes, and their length directions are perpendicular to each other.

[0070] For details, see Figure 5 The first through hole 221 is an elongated oval hole extending along a first direction on the surface of the support plate 22, and the third through hole 222 is an elongated oval hole extending along a second direction on the surface of the support plate 22, wherein the first direction is perpendicular to the second direction. This structure allows for greater machining errors and facilitates adjustment of the position of the fixing screw 27 in the horizontal plane during assembly to adapt to different manufacturing and assembly requirements.

[0071] In some embodiments, both the outer pool wall 31 and the inner pool wall 32 include a plurality of circumferentially arranged arc-shaped pool wall panels 311, and adjacent arc-shaped pool wall panels 311 are connected by a socket joint.

[0072] For example, see Figure 6 The two adjacent arc-shaped pool wall panels 311 are connected by a socket structure. The socket structure includes a rectangular socket tube 313 disposed between the two adjacent arc-shaped pool wall panels 311. One side of the rectangular socket tube 313 is welded to one of the arc-shaped pool wall panels 311, and the other side of the rectangular socket tube 313 is provided with a slot 3131. The other arc-shaped pool wall panel 311 is inserted into the slot 3131 and bolted to the rectangular socket tube 313.

[0073] For details, see Figure 6 The right side of the rectangular socket tube 313 is welded to the right side arc-shaped pool wall plate 311. The left side of the rectangular socket tube 313 is provided with a slot 3131 extending from one end to the other. The width of the slot 3131 is slightly larger than the thickness of the arc-shaped pool wall plate 311. The right end of the left side arc-shaped pool wall plate 311 passes through the slot 3131 and extends into the rectangular socket tube 313. The limiting bolt 315 passes through the rectangular socket tube 313 and the left side arc-shaped pool wall plate 311 and is threadedly connected to the limiting nut 316.

[0074] Multiple limiting bolts 315 are provided, spaced apart along the length of the rectangular socket tube 313. Tightening the limiting nut 316 pulls the rectangular socket tube 313 tight, preventing the slot 3131 from opening. To further enhance the connection between adjacent arc-shaped pool wall panels 311, a limiting plate 317, welded to the arc-shaped pool wall panel 311, is inserted into the rectangular socket tube 313.

[0075] To improve the strength and rigidity of the arc-shaped pool wall panel 311, see [reference needed]. Figure 1 , Figure 6 A reinforcing plate 312 is provided on the outer surface of the arc-shaped pool wall panel 311. Multiple reinforcing plates 312 may be provided, spaced apart from top to bottom. By providing the reinforcing plates 312, the strength and rigidity of the arc-shaped pool wall panel 311 can be increased, preventing instability under external forces. For example, the reinforcing plate 312 can be made of angle steel, and the reinforcing plate 312 and the arc-shaped pool wall panel 311 can be connected by continuous welding or intermittent welding.

[0076] After several arc-shaped pool wall panels 311 are assembled together, reinforcing plates 312 located at the same height can be connected together by fixing plates 314 to form a reinforcing ring, further increasing the rigidity and stability of the prefabricated pool body 3. The two ends of the fixing plate 314 can be connected to two adjacent reinforcing plates 312 respectively by bolts.

[0077] The partition 33 can be welded to the outer pool wall 31 and the inner pool wall 32, respectively. See also the following embodiments: Figure 7 The partition 33 is bolted to the outer pool wall 31 and the inner pool wall 32 respectively.

[0078] For example, taking the connection structure between the partition 33 and the outer pool wall 31 as an example, a connecting rib 318 extending from top to bottom is welded onto the arc-shaped pool wall panel 311 of the outer pool wall 31. The connecting rib 318 can be made of angle steel, and a gasket is provided between the connecting rib 318 and the partition 33 and they are connected together by bolts. To improve the strength and rigidity of the partition 33, see [reference needed]. Figure 1 , Figure 7 The surface of partition 33 is welded with transverse angle steel and longitudinal angle steel.

[0079] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
