Abstract
Description
Technical Field
[0001] This application relates to the field of V-groove technology for filter beds, and in particular to a drainage fixing structure for V-groove in filter beds. Background Technology
[0002] In the field of water treatment, filters are one of the most crucial infrastructure components, playing an irreplaceable role in purifying water and removing impurities. During the construction of the V-shaped channel of the filter, the water pipes are usually pre-installed at the designed locations according to the construction drawings. Finally, concrete is poured to form an inclined plate, and water flows within the V-shaped channel formed between the inclined plate and the partition wall, then flows out through the water pipes, facilitating subsequent filtration.
[0003] However, during the concrete pouring process, phenomena such as tilting or shifting of the water pipe may occur. Consequently, when the water in the V-shaped trough flows out through the water pipe, phenomena such as water flow deviation and turbulence may occur, resulting in different overall filtration capacity of each filter tank. Ultimately, this leads to some workshops being overloaded for filtration and others being underloaded for filtration. Utility Model Content
[0004] This application provides a drainage fixing structure for a V-shaped groove in a filter bed, which solves the problem of the water pipes on the current V-shaped groove of the filter bed being unstable.
[0005] A filter tank V-shaped groove drainage fixing structure includes:
[0006] The filter includes a first partition wall and a second partition wall. There are two first partition walls that extend along the length direction. The two first partition walls are spaced apart along the width direction. There are multiple second partition walls that extend along the width direction. The multiple second partition walls are spaced apart along the length direction. The two ends of the second partition walls are respectively connected to the two first partition walls.
[0007] An inclined plate is provided on the second partition wall and connected to the two first partition walls along the width direction. The inclined plate is inclined upward along the length direction. Multiple water pipes are provided and all pass through the inclined plate.
[0008] A fixing element is provided inside the inclined plate and fixed to the water pipe.
[0009] By adopting the above technical solution, the inclined plate is set on the second partition wall, the water pipe passes through the inclined plate, and both the fixing component and the water pipe can be covered by the inclined plate and fixed to the water pipe. The stability of the water pipe is further ensured by the fixing component, so that the water pipe will not be deflected by force when the concrete is poured to form the inclined plate, thus ensuring that the filter pool drainage system can drain water stably.
[0010] In one embodiment, the fastener includes a plurality of reinforcing bars, which are laid within the inclined plate and inclined upwards. The water pipe is fixedly connected to the reinforcing bars, and the inclined plate is made of cast concrete.
[0011] By adopting the above technical solution, the reinforcing bars are first placed inside the inclined slab and tilted upwards. This enhances the strength and toughness of the inclined slab during concrete pouring, enabling it to withstand water flow pressure and other external forces, extending the service life of the inclined slab, and ensuring the stability of the filter drainage system. The water pipes are fixedly connected to the reinforcing bars, making the pipes more securely fixed within the inclined slab, effectively preventing pipe displacement or loosening, ensuring stable drainage performance, and improving the reliability of the drainage system.
[0012] In one embodiment, the fastener further includes a plurality of sleeves, which are fixed to the reinforcing bars. The sleeves are provided with internal threads, and the water pipes are provided with external threads. The sleeves are fitted onto the corresponding water pipes.
[0013] By adopting the above technical solution, the sleeve can protect the water pipe, preventing it from being impacted or corroded by external forces, extending its service life, and ensuring the normal operation of the drainage system. The sleeve further strengthens the connection between the water pipe and the fixing components, making the fixation of the water pipe within the inclined plate more reliable, better able to withstand the impact of water flow and other external forces, and improving the stability of the drainage system.
[0014] In one embodiment, the fastener further includes a stirrup located at one end of the water pipe near the second partition wall, and the stirrup is fixed to the reinforcing bar and the water pipe.
[0015] By adopting the above technical solution, the stirrup can keep the water pipe horizontal, avoiding phenomena such as water flow deviation and turbulence caused by uneven water pipe height, making the water flow more stable, improving the uniformity and effectiveness of drainage, and ensuring the normal operation of the filter tank drainage system. In addition, the stirrup further enhances the stability of the water pipe and prevents the water pipe from moving.
[0016] In one embodiment, the filter tank V-shaped trough drainage fixing structure further includes a first template, which is located at the lower end of the inclined plate and tilted upwards. The first template abuts against the inclined plate, and the end of the water pipe away from the second partition wall extends into the first template.
[0017] By adopting the above technical solution, the first template is set at the lower end of the inclined plate and tilted upwards, which can support the concrete and other materials when pouring building materials, prevent the materials from flowing out and causing waste, thereby saving building materials and reducing construction costs.
[0018] In one embodiment, the outer surface of the first template is provided with a plurality of water passage holes, all of which are flush with the horizontal direction, and the water passage pipe passes through the corresponding water passage hole and is fixed to the stirrup.
[0019] By adopting the above technical solution, the water pipes are perforated and fixed with stirrups, ensuring the horizontality of multiple water pipes. During backwashing, each water pipe can flush impurities floating on the water surface towards the center, allowing impurities to be collected and discharged more effectively, improving the backwashing effect, ensuring the filtration performance of the filter bed, and extending the service life of the filter bed.
[0020] In one embodiment, the opening diameter of the water passage hole is 35mm, the diameter of the water passage pipe is 32mm, and the horizontal spacing between the water passage pipes is 200mm.
[0021] By adopting the above technical solution, such size settings can ensure the matching accuracy between the water pipe and the water hole, so that the water can flow smoothly through the water pipe and out. At the same time, the reasonable spacing between the water pipes can meet the needs of drainage and backwashing, ensuring the water flow capacity and drainage efficiency of the filter bed, and avoiding filter bed operation problems caused by insufficient water flow capacity or poor water flow.
[0022] In one embodiment, the water pipe is made of materials such as PVC, HDPE, or ceramic.
[0023] By adopting the above technical solutions, suitable materials can be selected according to different application scenarios and needs. For example, PVC pipes are low in cost and easy to construct; HDPE pipes are corrosion-resistant and wear-resistant; ceramic pipes have strong corrosion resistance and smooth inner walls, which can meet the requirements of different water qualities and environments, and improve the adaptability of the filter drainage system to different working conditions.
[0024] In one embodiment, the first partition wall is provided with a plurality of water inlets, which are trapezoidal and capable of discharging water toward the corresponding inclined plate.
[0025] By adopting the above technical solution, the trapezoidal inlet design facilitates water collection and flow, ensures the rationality of water intake, and enables water to be evenly distributed in the V-shaped groove between the inclined plate and the second partition wall, thereby improving the water intake efficiency and uniformity of the filter and ensuring the normal operation of the filter.
[0026] In one embodiment, the first partition wall is further provided with a filter element located at the water inlet.
[0027] By adopting the above technical solutions, the filter elements can effectively intercept larger particulate impurities in the water, prevent impurities from entering the filter tank, reduce the possibility of blockage in the water pipe and inside the filter tank, ensure the smooth flow of the drainage system, improve the operating efficiency and service life of the filter tank, and reduce maintenance costs.
[0028] In summary, this application includes at least one beneficial effect:
[0029] 1. An inclined plate is installed on the second partition wall, and the water pipe passes through the inclined plate. Both the fixing component and the water pipe can be covered by the inclined plate and fixed to the water pipe. The stability of the water pipe is further ensured by the fixing component, so that the water pipe will not be deflected by force when the concrete is poured to form the inclined plate, thus ensuring that the filter pool drainage system can drain water stably.
[0030] 2. The sleeve protects the water pipe from external impacts or corrosion, extending its service life and ensuring the normal operation of the drainage system. The sleeve further strengthens the connection between the water pipe and the fixing components, making the pipe's fixation within the inclined plate more reliable, better able to withstand water flow impacts and other external forces, and improving the stability of the drainage system.
[0031] 3. Stirrups keep the water pipes level, preventing uneven water flow that could lead to turbulence or other problems. This results in a more stable flow, improved drainage uniformity and efficiency, and ensures the normal operation of the filter drainage system. Furthermore, stirrups enhance the stability of the water pipes, preventing them from shifting. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-3 The V-shaped groove drainage fixing structure of the filter tank provided in this application will be described in further detail.
[0037] Example 1
[0038] Please see Figure 1-3 The filter tank V-shaped groove drainage fixing structure 1 provided in this application embodiment includes a filter tank 11, an inclined plate 12, a water pipe 13 and a fixing member 14.
[0039] like Figure 1 As shown, the filter tank 11 includes a first partition wall 111 and a second partition wall 112. Two first partition walls 111 are provided and extend along the length direction, spaced apart along the width direction. Multiple second partition walls 112 are provided and extend along the width direction, spaced apart along the length direction. The two ends of each second partition wall 112 are connected to two first partition walls 111. The first partition wall 111 is characterized by its strength and stability, and its material can be common building materials such as reinforced concrete or bricks. In applications requiring high durability of the filter tank 11, high-strength reinforced concrete can be used, as this material can withstand greater pressure and impact. The arrangement of the first partition wall 111 ensures the structural stability of the filter tank 11, providing a foundation for the installation of subsequent components. The second partition wall 112 also needs to possess sufficient strength, and its material can be the same as the first partition wall 111. The function of the second partition wall 112 is to further divide the internal space of the filter tank 11, providing support points for the subsequent installation of the inclined plate 12. Specifically, a filtration space 113 is formed between two adjacent second partition walls 112 and two first partition walls 111. Filter material is placed in the filtration space 113 for filtering water. One filter tank 11 may include multiple filtration spaces 113. The upper surfaces of the first partition walls 111 and the second partition walls 112 may also be equipped with railings to prevent people from falling.
[0040] like Figure 2 As shown, the inclined plate 12 is set on the second partition wall 112 of the filter tank 11 and is connected to the two first partition walls 111 at both ends along the width direction. Multiple water pipes 13 are provided and pass through the inclined plate 12. Fixing members 14 are set inside the inclined plate 12 and fixed to the water pipes 13. Both the fixing members 14 and the water pipes 13 are covered by the inclined plate 12. This structure enhances the fixing effect of the water pipes 13, prevents them from shifting and loosening during long-term use, and ensures the stability and uniformity of the drainage of the filter tank 11.
[0041] Specifically, the inclined plate 12 is cast from building materials and slopes upwards along its length, serving to guide the water flow. The building materials can include concrete, cement mortar, etc. Taking concrete as an example, it has good plasticity and strength after hardening. The water pipe 13 is made of materials such as PVC, HDPE, and ceramics. Taking PVC as an example, it has advantages such as corrosion resistance and light weight. The function of the water pipe 13 is to discharge water from the filter tank 11 to the filtration space 113.
[0042] The fastener 14 may include multiple reinforcing bars, all of which are laid within the inclined plate 12 and inclined upwards. The water pipe 13 is fixedly connected to the reinforcing bars. The reinforcing bars are characterized by high strength and toughness, and their type can be selected according to actual needs. Specifically, threaded steel bars can be used, as their threads allow for better bonding with concrete and enhance the structural strength of the inclined plate 12. The water pipe 13 can be fixed to the reinforcing bars by welding or binding. In actual construction, the reinforcing bars can be arranged according to the design requirements first, then the water pipe 13 can be fixed to the reinforcing bars, and finally the concrete can be poured. This ensures that the water pipe 13 is more firmly fixed within the inclined plate 12.
[0043] The fastener 14 also includes a stirrup 141, which is located at the end of the water pipe 13 near the second partition wall 112. The stirrup 141 is fixed to the water pipe 13 and the reinforcing steel. The stirrup 141 is generally made of metal, such as steel. It can support the water pipe 13, ensuring that the water pipe 13 remains horizontal and further fixing the water pipe 13, so that the water flow is stable and avoids water flow deviation and turbulence caused by uneven water passage 151.
[0044] The filter tank V-shaped trough drainage fixing structure 1 also includes a first template 15. The first template 15 is located at the lower end of the reinforcing bars and is inclined upwards. The end of the water pipe 13 away from the second partition wall 112 extends into the first template 15. Specifically, the first template 15 has multiple water holes 151, which are flush horizontally aligned. The water pipe 13 extends into each corresponding water hole 151. The function of the first template 15 is to facilitate support during concrete pouring, preventing material waste, and ensuring that the concrete can completely cover the reinforcing bars to form the inclined plate 12. The first template 15 can be made of materials such as wood or plastic, and its material needs to have a certain degree of hardness and flatness. In this embodiment, the outer surface of the first template 15 is marked with marking lines to determine the elevation of the water holes 151 before drilling. The opening diameter of the water passage hole 151 is 35mm, the diameter of the water passage pipe 13 is 32mm, and the horizontal spacing between the water passage pipes 13 is 200mm. This size design ensures that the water passage pipes 13 are horizontal, so that during backwashing, each water passage pipe 13 can flush the impurities floating on the water surface toward the center and collect them.
[0045] The first partition wall 111 is provided with a water inlet 1111, which is trapezoidal and can discharge water into the V-shaped channel formed between the inclined plate 12 and the second partition wall 112. The trapezoidal design of the water inlet 1111 allows water to flow more evenly into the V-shaped channel. The first partition wall 111 is also provided with a filter element, which is located at the water inlet 1111. The filter element can be a filter screen, sponge, or filter, etc. Its function is to prevent large particles of impurities from entering the filter tank 11, avoiding blockage of the water pipe 13 and affecting the drainage effect.
[0046] The implementation principle of this embodiment is as follows: First, the first partition wall 111 and the second partition wall 112 are poured. At this time, the reinforcing bars extend from the second partition wall 112 and are located at the position of the inclined plate 12. Then, the first template 15 is fixed to the second partition wall 112 and located at the lower end of the reinforcing bars. Water passage holes 151 are opened according to the marking lines on the first template 15. Then, one end of the water passage pipe 13 is inserted into the water passage hole 151, and the other end is fixed to the stirrup 141 and the reinforcing bars. At the same time, the stirrup 141 is fixed to the reinforcing bars to keep the water passage pipes 13 flush. Then, the concrete is poured from bottom to top and covers the reinforcing bars, stirrup 141 and water passage pipes 13. Then, the elevation of the concrete and the width along the length direction are controlled to be consistent. Finally, after cooling to form the inclined plate 12, the first template 15 is removed and the part of the water passage pipe 13 extending out of the inclined plate 12 is cut off.
[0047] The entire V-shaped trough drainage fixing structure 1 of the filter pool provides a stable installation foundation for subsequent components through the reasonable setting of the partition wall structure of the filter pool 11. The setting of the inclined plate 12 guides the water flow direction, and the water pipe 13 realizes the flow and discharge of water. The steel bars and stirrups 141 in the fixing component 14 enhance the fixing effect of the water pipe 13, ensuring the levelness and stability of the water pipe 13. The first template 15 facilitates the construction of building materials, and the design of the water passage hole 151 ensures the levelness between the water pipes 13 and the backwashing effect. The trapezoidal design of the inlet 1111 and the setting of the filter components further optimize the water inlet and drainage functions of the filter pool 11. Compared with the existing drainage construction method of the filter pool 11, this structure effectively solves the problem of easy displacement and loosening of the water pipe 13, improves the stability and uniformity of the drainage of the filter pool 11, and enhances the overall performance of the filter pool 11.
[0048] Example 2
[0049] like Figure 3 As shown, this embodiment differs from the previous embodiment in that the fixing member 14 may further include multiple sleeves 142, each sleeve 142 being fixed to a reinforcing bar. Each sleeve 142 has an internal thread, and the water pipe 13 has an external thread. The sleeve 142 is fitted onto its corresponding water pipe 13. The sleeves 142 can be made of metal, such as stainless steel, which has good corrosion resistance and strength. At this time, the stirrup 141 is also fixed to the sleeves 142 to ensure that the multiple sleeves 142 are flush and horizontally positioned.
[0050] The implementation principle of this embodiment is as follows: by connecting the sleeve 142 to the water pipe 13 by thread, not only is the water pipe 13 fixed, but it can also play a certain protective role in preventing the water pipe 13 from being damaged by external impact.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
