Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a side filter for a clean circulating water system. Background Technique

[0002] The side filter of the clean circulating water system is a filtering device specially used in the fields of industrial cooling water treatment, civil water purification treatment, etc. Its main function is to remove suspended solids, particulate matters and other impurities from the circulating water system to keep the water quality clean.

[0003] Traditional water treatment systems usually rely on a single filtering technology. This design not only limits the filtering effect, but also brings inconvenience in maintenance. Due to the lack of an efficient filter screen disassembly and assembly mechanism, when maintenance personnel clean or replace the filter screen, they often need to completely stop the machine and disassemble the entire filtering device. This process not only takes time, but also seriously affects the operation efficiency and production continuity of the system, increasing the maintenance cost and labor input. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a side filter for a clean circulating water system.

[0005] The utility model is realized by adopting the following technical scheme: a side filter for a clean circulating water system, including a main circulation pipe, the outer surface of the main circulation pipe is fixedly connected with a secondary branch pipe, an inlet throttle valve is arranged inside the secondary branch pipe, and the lower surface of the secondary branch pipe is fixedly connected with a secondary circulation pipe.

[0006] Through the above technical scheme, part of the water flow is extracted from the main circulation pipe through the secondary branch pipe and enters the side filter, which can more effectively remove suspended solids and impurities in the water, improve the cleanliness of the overall water system. The inlet throttle valve can adjust the water inflow of the secondary branch pipe, thereby controlling the flow rate entering the side filter, ensuring that the filter operates in the best working state, and at the same time avoiding the impact of excessive water flow on the filter.

[0007] As a further improvement of the above scheme, a filter cylinder is fixedly connected to the surface of the secondary circulation pipe, and vertical grooves are formed in the inner wall of the filter cylinder.

[0008] Through the above technical scheme, the vertical grooves play a guiding role to ensure the stability of the subsequent filter screen during disassembly and assembly.

[0009] As a further improvement of the above scheme, a first clamping block is slidably connected to the top of the vertical groove, and a primary activated filter screen is fixedly connected to the surface of the first clamping block.

[0010] Through the above technical solution, the first clamping block connected by sliding can facilitate the installation and replacement of the primary active filter screen. When it is necessary to clean or replace the filter screen, the primary active filter screen can be easily taken out by sliding the first clamping block for cleaning or replacement, improving the maintenance efficiency.

[0011] As a further improvement of the above solution, a support rod is fixedly connected to the lower surface of the first clamping block, and a second clamping block is fixedly connected to the bottom end of the support rod.

[0012] Through the above technical solution, the first clamping block and the second clamping block connected by the support rod can be installed and disassembled as a whole, simplifying the operation steps and improving the maintenance efficiency. Moreover, the support rod provides additional support, enhancing the connection stability between the first clamping block and the second clamping block, ensuring that the filter screen will not become loose or fall off due to water flow impact during use.

[0013] As a further improvement of the above solution, a secondary active filter screen is fixedly connected to the outer surface of the second clamping block, and both the primary active filter screen and the secondary active filter screen are slidably connected to the inner wall of the filter cylinder.

[0014] Through the above technical solution, by setting the primary active filter screen and the secondary active filter screen, multi-stage filtration can be achieved, effectively removing impurities, organic substances, and odors in water and improving water quality.

[0015] As a further improvement of the above solution, a drainage throttle valve is arranged on the inner bottom wall of the filter cylinder, and a return pipe is arranged on the lower surface of the drainage throttle valve.

[0016] Through the above technical solution, the size of the discharged water volume can be adjusted through the drainage throttle valve, thereby controlling the water level and flow rate in the filter cylinder to ensure the filtering effect. The drainage throttle valve can avoid discharging a large amount of water at one time, reducing water resource waste.

[0017] As a further improvement of the above solution, a support rod is fixedly connected to the lower surface of the filter cylinder, and a base is fixedly connected to the bottom end of the support rod.

[0018] Through the above technical solution, the support rod and the base provide stable support for the filter cylinder, ensuring that the equipment will not tilt or collapse due to water flow impact or other external forces during operation. Through the connection of the support rod and the base, the structural strength of the entire filtering device is enhanced, improving its pressure resistance and seismic performance.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] The utility model is provided with a guiding groove. Through the design of sliding connection, when it is necessary to clean or replace the filter screen, the operator only needs to slide the first clamping block, and through the connection of the supporting rod, the primary activated carbon filter screen and the secondary activated carbon filter screen can be easily taken out for cleaning or replacement. The dual filtration mechanism can effectively remove various impurities in water, significantly improve water quality. The filter screen adopts a quick disassembly and assembly design, which simplifies the maintenance process, thereby improving work efficiency and the overall reliability of the filtration system. In addition, by finely adjusting the inlet and drain throttle valves, while ensuring efficient filtration, the system maximally saves water, fully meeting the requirements of energy conservation and environmental protection.

Specific Embodiments

[0027] Next, in combination with the drawings and specific embodiments, the utility model will be further described. It should be noted that on the premise of no conflict, any combination of the following described embodiments or technical features can form a new embodiment. Embodiment

[0028] Please refer to Figures 1-4, the side-stream filter of the net circulating water system in this embodiment includes a main circulation pipe 1. A secondary branch pipe 2 is fixedly connected to the outer surface of the main circulation pipe 1. An inlet throttle valve 3 is arranged inside the secondary branch pipe 2. A secondary circulation pipe 4 is fixedly connected to the lower surface of the secondary branch pipe 2. The water flow in the main circulation pipe 1 is introduced into the side-stream filter through the secondary branch pipe 2. This process is achieved through the secondary circulation pipe 4, which is connected to the secondary branch pipe 2 and guides part of the water flow to the side-stream filter. The inlet throttle valve 3 is located inside the secondary branch pipe 2 and is used to adjust the water flow rate and flow volume entering the side-stream filter. By adjusting the opening degree of the throttle valve, the water volume entering the side-stream filter can be controlled to ensure that the filter is in the best working state.

[0029] A filter cylinder 5 is fixedly connected to the surface of the secondary circulation pipe 4. Vertical grooves 6 are formed on the inner wall of the filter cylinder 5. The main function of the vertical grooves 6 is to provide a guiding function, ensuring that when disassembling and assembling the filter screen, the filter screen can slide stably along the grooves, thereby maintaining the accurate position of the filter screen and avoiding deviation or damage of the filter screen during the disassembly and assembly process.

[0030] A first clamping block 7 is slidably connected to the top of the vertical groove 6. A primary activated filter screen 8 is fixedly connected to the surface of the first clamping block 7. Through the design of the sliding connection, the first clamping block 7 can slide up and down in the vertical groove 6, thereby driving the installation and disassembly of the primary activated filter screen 8. When it is necessary to clean or replace the filter screen, the operator only needs to slide the first clamping block 7 to easily take out the primary activated filter screen 8 for cleaning or replacement. This design greatly simplifies the process of replacing and maintaining the filter screen, improving the work efficiency and the reliability of the filtration system.

[0031] A support rod 9 is fixedly connected to the lower surface of the first clamping block 7. A second clamping block 10 is fixedly connected to the bottom end of the support rod 9. The first clamping block 7 and the second clamping block 10 connected by the support rod 9 can be installed and disassembled as a whole, simplifying the operation steps and improving the maintenance efficiency. Moreover, the support rod 9 provides additional support, enhancing the connection stability between the first clamping block 7 and the second clamping block 10 to ensure that the filter screen will not loosen or fall off due to water flow impact during use.

[0032] A secondary activated filter screen 11 is fixedly connected to the outer surface of the second clamping block 10. Both the primary activated filter screen 8 and the secondary activated filter screen 11 are slidably connected to the inner wall of the filter cylinder 5. By setting the primary activated filter screen 8 and the secondary activated filter screen 11, multi-stage filtration can be achieved. The primary activated filter screen 8 is mainly responsible for removing large particle impurities in the water, while the secondary activated filter screen 11 further removes organic matters, odors and other tiny impurities in the water. This multi-stage filtration method can significantly improve the water quality and ensure that the water in the water system meets the required cleaning standards.

[0033] The inner bottom wall of the filter cartridge 5 is provided with a drainage throttle valve 12. A return pipe 13 is provided on the lower surface of the drainage throttle valve 12. The main function of the drainage throttle valve 12 is to regulate the amount of discharged water, thereby controlling the water level and flow rate inside the filter cartridge 5. By adjusting the opening degree of the throttle valve, the discharge speed of water can be controlled to ensure that the water level inside the filter cartridge 5 is maintained within a suitable range, thereby optimizing the filtration effect. The drainage throttle valve 12 can avoid discharging a large amount of water at one time, reducing the waste of water resources. Through fine adjustment, the filtration system can save water to the greatest extent while maintaining high-efficiency filtration. This design not only improves the performance of the filtration system but also meets the requirements of energy conservation and environmental protection.

[0034] The lower surface of the filter cartridge 5 is fixedly connected with a support rod 14. The bottom end of the support rod 14 is fixedly connected with a base 15. The support rod 14 and the base 15 provide stable support for the filter cartridge 5, ensuring that the equipment will not tilt or collapse due to water flow impact or other external forces during operation. Through the connection of the support rod 14 and the base 15, the structural strength of the entire filtration device is enhanced, and its pressure resistance and seismic performance are improved.

[0035] The implementation principle of the side filter of the net cycle water system in the embodiment of this application is as follows: Start the net cycle water system. The water flow in the main circulation pipe 1 is guided by the secondary branch pipe 2, and the water flow rate and flow into the side filter are controlled by adjusting the inlet throttle valve 3. Part of the water flow is introduced into the filter cartridge 5 through the secondary circulation pipe 4. During this process, the water first contacts the primary active filter screen 8 to remove large particle impurities. Subsequently, the water flow passes through the secondary active filter screen 11 to further remove organic matter, odors, and other tiny impurities. When it is necessary to clean or replace the filter screen, the operator slides the first clamping block 7 to move it up and down in the vertical groove 6, so as to conveniently remove or install the primary active filter screen 8. At the same time, the first clamping block 7 and the second clamping block 10 connected by the support rod 9 are operated as a whole, simplifying the maintenance steps. The filtered water flows out through the drainage throttle valve 12. Adjusting the opening degree of the throttle valve can control the discharge speed of water, maintain an appropriate water level inside the filter cartridge 5, and optimize the filtration effect. The support rod 14 and the base 15 provide stable support for the filter cartridge 5, ensuring that the equipment will not tilt or collapse due to water flow impact or other external forces during operation.

[0036] The above implementation manners are only the preferred implementation manners of the present utility model and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the scope of protection required by the present utility model.
