Description

Technical Field

[0001] This utility model relates to the field of water source filtration technology in water plants, specifically a water source filtration device for water plants. Background Technology

[0002] Water source filtration equipment in water supply plants is one of the key facilities to ensure the safety of urban water supply and that water quality meets standards. In urban water supply, filtration equipment is usually installed at the inlet of the water supply unit to prevent impurities from flowing into the urban water system with the water, so as to provide clean and safe urban water.

[0003] Patent document CN223439319U discloses a water source filtration device for a water supply plant, comprising: a water supply unit, with a filter cartridge fixedly connected to the upper surface of the water supply unit; a cleaning mechanism, including a filter frame fixedly connected to the inner wall of the filter cartridge, a drain pipe fixedly connected to the lower surface of the filter cartridge, a spray pipe rotatably connected to the inner wall of the filter cartridge, a water tank fixedly connected to the top of the water supply unit, and a water pump fixedly connected to one end of the filter cartridge; this device, through a solenoid valve, a water pump, a water tank, and a spray pipe, achieves flushing water on one end of the filter frame, causing impurities at the other end of the filter frame to be discharged through the drain pipe with the water, preventing impurities from remaining in the filter frame. Compared to existing methods that scrape impurities from the filter frame without discharging them, this device flushes and discharges impurities from the filter frame, preventing excessive impurities from remaining in the filter frame and causing blockage, thus ensuring the water supply flow of the water supply equipment to the city.

[0004] Although the aforementioned application document allows impurities at the other end of the filter frame to be discharged with the water through the drain pipe, preventing impurities from remaining inside the filter frame, compared to the existing method of scraping the filter frame without discharging impurities, it washes out the impurities on the filter frame to prevent excessive impurities from remaining inside the filter frame and causing blockage, thus ensuring the water supply flow of the water supply equipment to the city, the cleaning process mainly relies on the water flow impact of the spray pipe and the impact of the batter bar on the filter frame. This impact is point-like and linear, resulting in incomplete cleaning of highly adhesive pollutants (such as oil stains and biofilms).

[0005] Therefore, a water source filtration device for water plants is proposed to solve the problems mentioned above. Utility Model Content

[0023] 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.

[0024] Example

[0025] See Figures 1-4This embodiment provides a water source filtration device for a water plant, including a filter cylinder body 1. A cleaning mechanism 2 is installed inside the filter cylinder body 1. An inlet pipe 3 is fixedly connected to the side of the filter cylinder body 1. An outlet pipe 4 is fixedly connected to the side of the filter cylinder body 1. A conical collection cylinder 6 is fixedly connected to the bottom of the filter cylinder body 1. A wastewater pipe 5 is fixedly connected to the bottom of the conical collection cylinder 6. A filter plate 7 is fixedly connected to the inner wall of the arc-shaped surface of the filter cylinder body 1. A cover is threadedly installed on the top of the filter cylinder body 1. A set of solenoid valves is respectively installed on the top of the inlet pipe 3, the outlet pipe 4, and the wastewater pipe 5. When filtering wastewater normally, the wastewater pipe 5 is closed. When cleaning the filter plate 7 is required, the inlet pipe 3 and the outlet pipe 4 are closed, and the wastewater pipe 5 is opened to discharge the impurities cleaned by the cleaning mechanism 2.

[0026] The cleaning mechanism 2 includes a limiting frame 21, which is fixedly connected to the inner wall of the arc-shaped surface of the filter cartridge body 1. A slide rod 22 is rotatably connected to the inner wall of the arc-shaped surface of the limiting frame 21. A scraper 23 is fixedly connected to the front of the slide rod 22. A connecting box 24 is fixedly connected to the top of the slide rod 22. A sliding groove 25 is opened inside the connecting box 24. A slider 27 is slidably connected to the inner wall of the sliding groove 25. A spring 26 is installed inside the connecting box 24. A connecting block 28 is fixedly connected to the upper surface of the slider 27. A rotating rod 29 is rotatably connected to the top of the inner wall of the filter cartridge body 1 through a bearing. A spraying component is installed on the top of the filter cartridge body 1.

[0027] When the rotating rod 29 rotates, it drives the entire connecting box 24 to make a circular motion through the connecting block 28. The connecting box 24 applies a radially outward force to the slider 27 and the sliding rod 22 through the spring 26, thereby forcing the scraper 23 to always be in close contact with the inner surface of the filter plate 7.

[0028] The motor 212 is started, which drives the rotating rod 29 to rotate. The rotating rod 29 drives the connecting block 28 to rotate, the connecting block 28 drives the slider 27 to rotate, the slider 27 drives the connecting box 24 to rotate, the connecting box 24 drives the sliding rod 22 to rotate, and the sliding rod 22 drives the scraper 23 to rotate. The scraper 23 scrapes away impurities on the top of the filter plate 7. During the rotation of the sliding rod 22, the limiting frame 21 drives the sliding rod 22 to move left and right. When the limiting frame 21 drives the sliding rod 22 to move to the right, the sliding rod 22 drives the connecting box 24 to move to the right. The connecting box 24 compresses the spring 26 through the sliding groove 25. When the spring 26 on the right is compressed, the spring 26 on the left will be stretched. The connecting box 24 slides on the outer wall of the slider 27 through the sliding groove 25, so that the scraper 23 can also move radially during the rotation.

[0029] See Figures 1-2 A motor 212 is fixedly connected to the upper surface of the filter cartridge body 1. A rotating rod 29 moves through the filter cartridge body 1, and the extended end of the rotating rod 29 extends toward the top of the filter cartridge body 1. The output end of the motor 212 is fixedly connected to the extended end of the rotating rod 29.

[0030] See Figures 2-3 A limiting groove 210 is provided on the inner wall of the arc-shaped surface of the filter cartridge body 1. A limiting rod 211 is slidably connected to the inner wall of the limiting groove 210. The limiting rod 211 is fixedly sleeved on the outer wall of the arc-shaped surface of the rotating rod 29. When the spring 26 applies pressure to the slider 27, the slider 27 will transmit the pressure to the rotating rod 29. However, the limiting rod 211 slides on the inner wall of the limiting groove 210, which further improves the compressive strength of the rotating rod 29. The limiting rod 211 and the limiting groove 210 constitute a guiding mechanism. The limiting rod 211 rotates with the rotating rod 29, but its outer edge slides in the limiting groove 210. This structure provides the rotating rod 29 with an additional support point away from the drive end.

[0031] Spring 26 is fixedly connected to the inner wall side of slide groove 25, and the end of spring 26 away from slide groove 25 is fixedly connected to the side of slider 27.

[0032] See Figures 1-2 The spraying assembly includes a water pipe 213, which is fixedly connected to the top of the filter cartridge body 1 and passes through the filter cartridge body 1. The extended end of the water pipe 213 extends into the filter cartridge body 1. By connecting the top of the water pipe 213 to an external water pump, the external water pump pumps in the liquid for cleaning the filter plate 7. The water pipe 213 transfers the liquid to the inside of the connecting pipe 214, and then the liquid is sprayed out through the nozzle 215 through the connecting pipe 214 to clean the filter plate 7. It is used in conjunction with the cleaning mechanism 2. The wastewater after cleaning is collected through the conical collection cylinder 6. The wastewater pipe 5 is opened to discharge the cleaning wastewater.

[0033] A connecting pipe 214 is fixedly connected to the bottom of the water pipe 213. The water pipe 213 and the connecting pipe 214 are connected in a continuous manner. A nozzle 215 is fixedly connected to the bottom of the connecting pipe 214. The connecting pipe 214 and the nozzle 215 divert and guide the water flow from the water pipe 213. The nozzle 215 enables the water flow to accurately spray onto the working area of ​​the scraper 23 and the surface of the filter plate 7, forming an effective rinsing curtain and greatly improving the efficiency of impurity transport.

[0034] The top of the limiting frame 21 has twenty-seven circular grooves for the sliding rod 22 to slide.

[0035] The slide bar 22 has a rounded corner on its side to fit the rounded groove. The size of the rounded groove is larger than the size of the rounded corner, which reduces the friction and wear of the slide bar 22 moving in the rounded groove, making the radial movement smoother and improving the life and responsiveness of the mechanism.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
