Description

Technical Field

[0001] This utility model relates to the field of swimming pool water filtration technology, specifically a swimming pool water activated carbon adsorption tank. Background Technology

[0002] Pool water filtration refers to the process of removing suspended particles, organic matter, microorganisms, residual chlorine and its byproducts from circulating water through physical and chemical means in order to maintain clear and hygienic water quality and ensure the health and comfort of users.

[0003] If an effective pre-filtration system is not installed before the pool water is treated with adsorption, large impurities in the water (such as hair, leaves, and algae fragments) will directly enter the activated carbon layer, causing blockage of the pores between the activated carbon particles. This affects the specific surface area utilization rate of the activated carbon, leading to a rapid decline in its adsorption capacity for residual chlorine, chloramines, and organic pollutants, shortening the lifespan of the activated carbon. It also causes a rapid decline in its adsorption capacity for other dissolved organic pollutants, affecting the quality of the effluent and making it difficult to achieve a consistently stable purification effect. Furthermore, during routine maintenance, operators need to use special tools to open the tank and remove the filter screen, greatly increasing the complexity of maintenance and labor costs. Especially in commercial pools with high usage frequency, large impurities accumulate quickly and cannot be cleaned quickly, forcing the system to shut down for extended periods and affecting the normal operation of the pool.

[0004] Therefore, this utility model provides an activated carbon adsorption tank for swimming pool water to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] The primary filter prioritizes the interception of large impurities, effectively preventing large particles such as hair and leaves from directly entering the activated carbon adsorption layer and causing pore blockage. This ensures the utilization rate of the specific surface area of ​​the activated carbon material, enabling it to continuously and stably adsorb residual chlorine, chloramine, and various dissolved organic pollutants. This extends the replacement cycle of activated carbon, reduces the pollution load on subsequent diatomaceous earth filter layers and activated carbon adsorption layers, and improves the stability and sustainability of the overall purification effect. The drive motor drives the threaded rod to raise and lower the connecting plate and mounting box, allowing the primary filter to automatically rise to a height for easy operation. With the handle, spring, and insertion rod, the primary filter can be disassembled and installed without tools, reducing maintenance complexity and manual labor intensity. It is especially suitable for high-frequency commercial swimming pool environments, enabling rapid cleaning even when impurities accumulate quickly, shortening downtime, ensuring the continuous operation of the pool system, and improving equipment availability and maintenance efficiency.

[0017] By setting up the first limiting block, the second limiting block, and the limiting groove, the diatomaceous earth filter plate and the activated carbon adsorption plate can be quickly installed and disassembled, simplifying the assembly process. The plates fit together tightly, enhancing the stability of each plate under the impact of water flow, preventing displacement or detachment due to vibration or water pressure changes, and ensuring the continuity of filtration.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides an activated carbon adsorption tank for swimming pool water, such as Figure 1 - Figure 5 As shown, the technical solution includes an adsorption tank 1, with a shell 4 fixedly connected to both sides of the adsorption tank 1. A threaded rod 13 is provided in the inner cavity of the shell 4. A connecting plate 15 is threadedly fitted onto the outer ring of the threaded rod 13. Insertion holes 16 are provided on both sides of the connecting plate 15. A diatomaceous earth filter layer 8 and an activated carbon adsorption layer 10 are provided in the inner cavity of the adsorption tank 1. A primary filter screen 6 is provided in the inner cavity of the adsorption tank 1. Mounting boxes 7 are fixedly connected to both sides of the primary filter screen 6. Mounting grooves 18 are provided on both sides of the mounting boxes 7. A fixing plate 22 is fixedly connected to the bottom of the inner cavity of the mounting groove 18. An insertion rod 19 is provided on one side of the fixing plate 22. A baffle plate 23 is fitted onto the outer ring of the insertion rod 19. A spring 20 is fitted onto the outer ring of the insertion rod 19.

[0027] A drive motor 17 is fixedly installed at the bottom of the outer casing 4. The top end of the threaded rod 13 is rotatably connected to the top of the corresponding inner cavity of the outer casing 4 through a rotating shaft. The bottom end of the threaded rod 13 is fixedly connected to the output shaft of the drive motor 17 through a bushing that passes through the bottom of the corresponding inner cavity of the outer casing 4. The drive motor 17 provides the power for the threaded rod 13 to rotate.

[0028] The inner cavity of the outer shell 4 is provided with a guide rod 14. The top end of the guide rod 14 is fixedly connected to the top of the corresponding inner cavity of the outer shell 4, and the bottom end of the guide rod 14 passes through one side of the corresponding connecting plate 15 and is fixedly connected to the bottom of the corresponding inner cavity of the outer shell 4. By setting the guide rod 14, the movement trajectory of the connecting plate 15 is restricted, and the connecting plate 15 is precisely guided and constrained.

[0029] One end of the spring 20 is fixedly connected to one side of the adjacent baffle 23, and the other end of the spring 20 is fixedly connected to one side of the corresponding fixing plate 22. The bottom end of the connecting plate 15 is embedded in the inner cavity of the corresponding mounting box 7. One end of the insertion rod 19 passes through the inner wall of the corresponding mounting groove 18 and is inserted into the inner cavity of the corresponding insertion hole 16. The other end of the insertion rod 19 passes through one side of the adjacent fixing plate 22 and is fixedly connected to a handle 21. The insertion rod 19 is inserted into the insertion hole 16 on the connecting plate 15 under the elastic force of the spring 20 to achieve locking. When disassembling, the operator pulls the handle 21 to drive the insertion rod 19 to overcome the elastic force of the spring 20 and move it away from the insertion hole 16, thereby releasing the locked state. This achieves the effect of quick and reliable connection and release between the connecting plate 15 and the mounting box 7. The disassembly and assembly operations can be completed without the use of tools, which improves the convenience of maintenance.

[0030] Limiting grooves 12 are provided on both sides of the inner wall of the adsorption tank 1. First limiting blocks 9 are fixedly connected to both sides of the diatomaceous earth filter plate 8, and second limiting blocks 11 are fixedly connected to both sides of the activated carbon adsorption plate 10. When installing the diatomaceous earth filter plate 8, the first limiting blocks 9 on both sides are aligned and slid into the limiting grooves 12 on the inner wall of the adsorption tank 1. When installing the activated carbon adsorption plate 10, the second limiting blocks 11 on both sides are also embedded into the limiting grooves 12, so that the diatomaceous earth filter plate 8 and the activated carbon adsorption plate 10 can be installed quickly and accurately, preventing displacement or detachment under the impact of water flow, and ensuring the continuity of filtration.

[0031] The outer surface of the mounting box 7 is slidably connected to the inner cavity of the corresponding limiting groove 12. The outer surface of the first limiting block 9 is slidably connected to the inner cavity of the corresponding limiting groove 12. The outer surface of the second limiting block 11 is slidably connected to the inner cavity of the corresponding limiting groove 12. When the mounting box 7 moves up and down in the vertical direction under the drive of the connecting plate 15, its outer surface and the inner cavity of the limiting groove 12 maintain a sliding fit.

[0032] A cover plate 2 is hinged to one side of the adsorption tank 1. A transmission pipe 3 is fixedly connected to the upper surface of the cover plate 2. A discharge pipe 5 is fixedly connected to one side of the adsorption tank 1. A valve is fixedly installed on the outer surface of the discharge pipe 5. Water enters the adsorption tank 1 through the transmission pipe 3. After purification, the water flows out from the discharge pipe 5. The flow of water is controlled by opening and closing the valve.

[0033] Specifically: Water is first transported through transmission pipe 3 to the primary filter 6 inside adsorption tank 1. The primary filter 6 effectively intercepts large impurities such as hair, leaves, and algae fragments. After primary filtration, the water continues to flow down to the diatomaceous earth filter plate 8. The microporous structure of the diatomaceous earth material deeply traps fine suspended particles, colloidal substances, and some microorganisms in the water, improving water clarity. Subsequently, the water flows into the activated carbon adsorption plate 10. The high specific surface area and abundant microporous structure of the activated carbon effectively remove residual chlorine, etc. Chloramine, urea, grease, and other soluble organic pollutants are efficiently adsorbed, thereby reducing the concentration of disinfection byproducts and improving the sensory indicators of the water. The clean water, after multi-stage purification, is discharged through the discharge pipe 5 and returned to the swimming pool. When maintaining the inside of the adsorption tank 1, the operator first flips the cover plate 2 to open the upper space of the adsorption tank 1, then starts the drive motor 17. The operator starts the drive motor 17 via an external controller. The output shaft of the drive motor 17 drives the threaded rod 13 to rotate. Because the connecting plate 15 is constrained by the guide rod 14... Therefore, the rotational motion of the threaded rod 13 is converted into the linear displacement of the connecting plate 15 in the vertical direction. When the connecting plate 15 moves upward, it drives the mounting box 7 fixed on it to rise synchronously. The rise of the mounting box 7 in turn drives the primary filter screen 6 to be lifted out of the adsorption tank 1, making it easier for the operator to directly contact and clean the impurities accumulated on the surface and inside of the primary filter screen 6. When the primary filter screen 6 needs to be replaced, the operator holds the handle 21 and applies a pulling force to the outside of the mounting box 7, so that the insertion rod 19 connected to the handle 21 overcomes the elastic force of the spring 20 and is released from the connecting plate. The plate is pulled out of the socket 16 on the 15, thereby releasing the locking state between the connecting plate 15 and the mounting box 7. At this time, the mounting box 7 and the primary filter screen 6 can be taken out as a whole for replacement or deep cleaning. The reverse operation can realize the quick reset and locking of the primary filter screen 6. When installing the diatomaceous earth filter plate 8, simply align the first limiting blocks 9 on both sides and embed them into the limiting grooves 12 on the inner wall of the adsorption tank 1 to achieve stable positioning. Similarly, the activated carbon adsorption plate 10 is installed by inserting the second limiting blocks 11 on both sides into the limiting grooves 12.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
