Description

Technical Field

[0001] This utility model relates to the field of disc filter technology, and more specifically, to a high-efficiency disc filter. Background Technology

[0002] Disc filters are an indispensable device in pipelines that transport media. They are usually installed at the inlet of pressure reducing valves, pressure relief valves, level control valves, or other equipment to remove impurities from the media and protect the valves and equipment from damage.

[0003] However, in the existing mechanism, the cylinder cover and the filter cylinder are connected by screws, which means that when personnel disassemble the filter plate inside the filter cylinder, they need to remove several screws, resulting in low efficiency in cylinder cover installation and disassembly.

[0004] A search revealed that Chinese patent CN221867595U discloses an energy-saving disc filter. This structure allows water flow to impact a rotating plate during filtration, causing a cleaning rod to rotate and automatically clean the filter plate surface, preventing clogging from long-term filtration and ensuring efficient water filtration. Furthermore, by turning the handle and using a gear-driven steering mechanism linked to a threaded rod, the insertion rod can be easily removed, enabling quick filter plate removal. Installation is the reverse process, greatly improving installation and disassembly efficiency. Moreover, when there are excessive impurities between the two filter plates, the filter plates can be easily removed for cleaning, ensuring the filtration device always maintains good filtration performance.

[0005] However, in actual use, the structure can automatically clean the surface of the filter plates by the water flow impacting the rotating plate during filtration, which drives the cleaning rod to rotate. Since the rotating plate can only clean the top filter plate, it cannot clean the bottom filter plates, which can easily lead to the bottom filter plates becoming clogged due to the accumulation of impurities, affecting the overall filtration effect and efficiency. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency disc filter to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-efficiency disc filter includes a filter cartridge, an inlet pipe extending through one side of the filter cartridge, an outlet pipe extending through the bottom of the filter cartridge, and a self-cleaning mechanism inside the filter cartridge.

[0009] The self-cleaning mechanism includes a storage box fixedly installed on the top of the filter cartridge. A connecting pipe is fixedly installed on the top of the storage box. A high-pressure water pump is installed on one side of the storage box. A delivery pipe is fixedly installed at the output end of the high-pressure water pump. Multiple connecting short pipes are installed through one end of the delivery pipe. One end of each of the multiple connecting short pipes passes through the filter cartridge and extends into the filter cartridge. A nozzle is installed through one end of each connecting short pipe.

[0010] By adopting the above technical solution: after being pressurized by a high-pressure water pump, high-pressure water is sprayed into the filter cartridge through a nozzle, which can powerfully clean impurities, ensure the efficient operation of the filter components, and achieve automatic cleaning through the compact structural design and the coordinated work of the components, thereby reducing manual disassembly and cleaning, and lowering maintenance costs and workload.

[0011] As a further description of the above technical solution: the filter cylinder is provided with a filtration mechanism, the filtration mechanism includes a heat dissipation box fixedly installed on the top of the filter cylinder, a motor is installed inside the heat dissipation box, a rotating shaft is fixedly installed at the output end of the motor, one end of the rotating shaft passes through the filter cylinder and extends into the filter cylinder, multiple collars are sleeved on the outside of the rotating shaft, and a fixing strip is fixedly installed at one end of each of the multiple collars, and one end of the fixing strip is connected to the inner wall of the filter cylinder.

[0012] By adopting the above technical solution: the motor drives the rotating shaft to rotate, causing the filter components fixed on the collar and fixing bar to rotate, increasing the contact opportunity between water and the filter components, improving filtration efficiency. During the rotation, the fixing bar and connected components can assist in cleaning the filter components, reducing the adhesion of impurities, and maintaining good filtration performance.

[0013] As a further description of the above technical solution: a cleaning brush is fixedly installed at the bottom of the fixing strip; a fixing ring is fixedly installed on the outside of the rotating shaft, and the fixing ring is rotatably connected to the collar; multiple filter discs are fixedly installed on the outside of the rotating shaft, the aperture of the multiple filter discs decreases sequentially from top to bottom, and each of the multiple filter discs has a sliding groove on its surface; a slider is fixedly installed at the bottom of the fixing strip, and the slider is slidably connected to the sliding groove; a drain pipe is fixedly installed at the top of the filter cylinder; a water inlet pipe is fixedly installed at the bottom of the filter cylinder; and a solenoid valve is fixedly installed on one side of each of the water inlet pipe, water outlet pipe, connecting pipe, drain pipe, and water inlet pipe.

[0014] By adopting the above technical solution, efficient multi-stage interception of impurities of different particle sizes can be achieved, ensuring the filtration effect. Each pipeline is equipped with a solenoid valve, which can flexibly control the water flow direction and on / off state, and facilitate different working modes such as filtration and self-cleaning.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up a self-cleaning mechanism, compared with existing technologies, the high-pressure water pump pressurizes the water and sprays high-pressure water onto the filter discs through the nozzle, which can effectively wash away surface and pore impurities. In conjunction with the motor driving the filter discs to rotate, the comprehensiveness and force of the water flow are enhanced, making cleaning more efficient. The collar and fixed ring are rotatably connected, providing stable support for the collar and ensuring the stability of the cleaning structure during operation, ensuring the smooth progress of the self-cleaning process. Secondly, the cleaning bristles at the bottom of the fixed strip move on the surface of the filter discs, and the slider slides in the groove, allowing the cleaning bristles to sweep along a specific trajectory, achieving comprehensive cleaning of the filter discs, effectively restoring filtration performance, extending the filter's service life, and reducing maintenance costs.

[0017] 2. By setting up a filtration mechanism, compared with existing technologies, a multi-stage filtration method is adopted. The pore size of the filter discs decreases from top to bottom, which can effectively intercept impurities of different particle sizes, ensuring good water quality and meeting subsequent usage requirements. By controlling the opening and closing of each solenoid valve, as well as the start and stop of the high-pressure water pump and motor, it can easily switch between filtration and self-cleaning modes, reducing manual maintenance costs and achieving continuous and efficient filtration.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The embodiments disclosed in this application are as follows: Figure 1-5 The high-efficiency disc filter shown includes a filter cylinder 1, an inlet pipe 2 through one side of the filter cylinder 1, an outlet pipe 3 through the bottom of the filter cylinder 1, and a self-cleaning mechanism inside the filter cylinder 1.

[0026] The self-cleaning mechanism includes a storage box 4 fixedly installed on the top of the filter cartridge 1. A connecting pipe 5 is fixedly installed on the top of the storage box 4. A high-pressure water pump 6 is installed on one side of the storage box 4. A delivery pipe 7 is fixedly installed at the output end of the high-pressure water pump 6. Multiple connecting short pipes 8 are connected through one end of the delivery pipe 7. One end of each of the multiple connecting short pipes 8 passes through the filter cartridge 1 and extends into the filter cartridge 1. A nozzle 9 is installed through one end of each connecting short pipe 8. When a certain amount of impurities accumulates on the filter disc 17, causing a decrease in filtration efficiency, the self-cleaning stage begins. At this time, the inlet pipe 2 and the outlet pipe... The solenoid valve 22 on one side of the 3 is closed, stopping the normal flow of filtered water. The solenoid valve 22 on the other side of the connecting pipe 5 is opened, and the clean water enters the storage box 4 through the connecting pipe 5 for storage. The high-pressure water pump 6 is started, which draws out the water in the storage box 4 and pressurizes it. The pressurized water is transported through the delivery pipe 7. Multiple connecting short pipes 8 at one end of the delivery pipe 7 introduce high-pressure water into the filter cylinder 1. The nozzle 9 at one end of the connecting short pipe 8 sprays high-pressure water onto the filter disc 17 at a certain angle and pressure. The impact force of the high-pressure water can wash away the impurities attached to the surface and pores of the filter disc 17.

[0027] Reference Figure 2-3As shown, a filtration mechanism is installed inside the filter cartridge 1. The filtration mechanism includes a heat dissipation box 10 fixedly mounted on the top of the filter cartridge 1. A motor 11 is installed inside the heat dissipation box 10. A rotating shaft 12 is fixedly mounted on the output end of the motor 11. One end of the rotating shaft 12 passes through the filter cartridge 1 and extends into the filter cartridge 1. Multiple collars 13 are sleeved on the outside of the rotating shaft 12. A fixing strip 14 is fixedly mounted on one end of each collar 13. One end of the fixing strip 14 is connected to the inner wall of the filter cartridge 1. During high-pressure water rinsing, the motor 11 inside the heat dissipation box 10 starts, and its output end... The rotating shaft 12 starts to rotate, driving multiple filter discs 17 to rotate. Multiple collars 13 are sleeved on the outside of the rotating shaft 12, and the collars 13 are rotatably connected to the fixed ring 16, which serves to support and stabilize the collars 13. As the rotating shaft 12 rotates, the cleaning bristles 15 at the bottom of the fixed bar 14 move on the surface of the filter discs 17 to further remove impurities, thereby driving the slider 19 at the bottom of the fixed bar 14 to slide in the groove 18 on the surface of the filter discs 17, ensuring that the cleaning bristles 15 can thoroughly clean the filter discs 17 along a specific trajectory.

[0028] Reference Figure 4-5As shown, a cleaning brush bristle 15 is fixedly installed at the bottom of the fixing strip 14, a fixing ring 16 is fixedly installed on the outside of the rotating shaft 12, the fixing ring 16 is rotatably connected to the collar 13, multiple filter discs 17 are fixedly installed on the outside of the rotating shaft 12, the aperture of the multiple filter discs 17 decreases from top to bottom, and each of the multiple filter discs 17 has a sliding groove 18. A slider 19 is fixedly installed at the bottom of the fixing strip 14, and the slider 19 is slidably connected to the sliding groove 18. A drain pipe 20 is fixedly installed at the top of the filter cylinder 1, and a water inlet pipe 21 is fixedly installed at the bottom of the filter cylinder 1. A solenoid valve 22 is fixedly installed on one side of the water inlet pipe 2, the water outlet pipe 3, the connecting pipe 5, the drain pipe 20, and the water inlet pipe 21, connecting the water inlet pipe 20 to the outside of the filter cylinder 1. The filter is connected to the water source that needs to be filtered. Then, the solenoid valve 22 on the side of the inlet pipe 2 is opened, and the water to be filtered enters the filter cylinder 1 through the inlet pipe 2. Since the solenoid valve 22 on the side of the outlet pipe 3 at the bottom of the filter cylinder 1 is also in the open state, the water flows in the filter cylinder 1, ready for filtration. The filter cylinder 1 is equipped with multiple filter discs 17, and the pore size of these filter discs 17 decreases from top to bottom. The water first passes through the upper filter discs 17 with larger pore size, and larger particles are intercepted. As the water continues to flow downward, it passes through the filter discs 17 with gradually smaller pore size, and smaller impurities are further intercepted. Through this multi-stage filtration method, efficient filtration of impurities of different particle sizes in the water is achieved. The filtered water flows out from the outlet pipe 3 for subsequent use. At the same time, the solenoid valve 22 on the inlet pipe 21 and the drain pipe 20 side is opened, and the impurities washed off are discharged from the filter cartridge 1 through the drain pipe 20 with the water flow. When the self-cleaning process is completed, the high-pressure water pump 6 and the motor 11 are turned off, and the solenoid valve 22 on the connecting pipe 5, the inlet pipe 21 and the drain pipe 20 side is closed. The solenoid valve 22 on the inlet pipe 2 and the outlet pipe 3 side is opened, and the filter cartridge 1 re-enters the normal filtration working state and continues to filter the incoming water efficiently.

[0029] Working principle of this utility model:

[0030] This utility model is a high-efficiency disc filter. In use, the inlet pipe 2 is connected to an external water source requiring filtration. Then, the solenoid valve 22 on one side of the inlet pipe 2 is opened, allowing the water to enter the filter cylinder 1. Since the solenoid valve 22 on the outlet pipe 3 at the bottom of the filter cylinder 1 is also open, the water flows within the filter cylinder 1, ready for filtration. The filter cylinder 1 contains multiple filter discs 17, with the pore size decreasing from top to bottom. The water first passes through the upper filter discs 17 with larger pores, where larger particles are intercepted. As the water continues to flow downwards, it passes through the gradually decreasing pore size filter discs 17, further intercepting smaller impurities. This multi-stage filtration method achieves high-efficiency filtration of impurities of different particle sizes in the water. The filtered water flows out from the outlet pipe 3 for subsequent use.

[0031] When a certain amount of impurities accumulate on the filter disc 17, causing a decrease in filtration efficiency, the self-cleaning stage begins. At this time, the solenoid valve 22 on the inlet pipe 2 and outlet pipe 3 side closes, stopping the normal flow of filtered water. The solenoid valve 22 on the connecting pipe 5 side opens, and the cleaning water enters the storage box 4 through the connecting pipe 5 for storage. The high-pressure water pump 6 starts, extracts and pressurizes the water in the storage box 4, and the pressurized water is transported through the delivery pipe 7. Multiple connecting short pipes 8 at one end of the delivery pipe 7 introduce high-pressure water into the filter cylinder 1. The nozzle 9 at one end of the connecting short pipe 8 sprays high-pressure water onto the filter disc 17 at a certain angle and pressure. The impact force of the high-pressure water can wash away the impurities attached to the surface and pores of the filter disc 17.

[0032] While the high-pressure water is rinsing, the motor 11 inside the heat sink box 10 starts, and the rotating shaft 12 at its output end begins to rotate. The rotating shaft 12 drives multiple filter discs 17 to rotate, and multiple collars 13 are sleeved on the outside of the rotating shaft 12. The multiple collars 13 are rotatably connected to the fixed ring 16, which plays the role of supporting and stabilizing the collars 13. As the rotating shaft 12 rotates, the cleaning bristles 15 at the bottom of the fixed bar 14 move on the surface of the filter discs 17 to further remove impurities, thereby driving the slider 19 at the bottom of the fixed bar 14 to slide in the groove 18 on the surface of the filter discs 17, ensuring that the cleaning bristles 15 can thoroughly clean the filter discs 17 along a specific trajectory.

[0033] At the same time, the solenoid valve 22 on the inlet pipe 21 and the drain pipe 20 side is opened, and the impurities washed off are discharged from the filter cartridge 1 through the drain pipe 20 with the water flow. When the self-cleaning process is completed, the high-pressure water pump 6 and the motor 11 are turned off, and the solenoid valve 22 on the connecting pipe 5, the inlet pipe 21 and the drain pipe 20 side is closed. The solenoid valve 22 on the inlet pipe 2 and the outlet pipe 3 side is opened, and the filter cartridge 1 re-enters the normal filtration working state and continues to perform efficient filtration on the incoming water.

[0034] 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.
