Description

Technical Field

[0001] This invention relates to the field of wastewater filtration equipment, specifically to a wastewater filter device and its operation method for a hydropower station. Background Technology

[0002] Currently, hydropower stations generate a large amount of wastewater when using hydropower for power generation. If discharged directly, it will cause water pollution. The existing treatment method is to purify the wastewater through filtration devices for reuse. However, because the wastewater contains a lot of impurities, it is easy to clog the filter screen. The wastewater filtration device is to let the wastewater enter through the inlet equipped with the filter screen and then discharge it through the outlet, so as to remove large particles and suspended solids from the wastewater, thereby achieving the effect of purifying the fluid.

[0003] According to a patent document with publication number CN215232490U, a wastewater filtration device for a hydropower station includes a filter box. An inlet pipe is installed on one side of the filter box, and a water pump is installed at one end of the inlet pipe. Three scrapers are installed inside the filter box, and connecting rods are installed on both sides of the top of each scraper. The tops of several connecting rods are fixedly connected to the bottom of a lifting plate. An electric telescopic rod is installed in the middle of the top of the lifting plate. In use, the piston rod of the electric telescopic rod pushes the lifting plate downwards, which in turn pushes several connecting rods at its bottom downwards. At this time, the connecting rods push the three scrapers at their bottom to scrape the sludge off the filter screen into the sludge recovery box, thus removing the sludge from the filter screen without disassembling it. However, while this solution cleans the sludge, it cannot select the filter plate aperture according to different wastewater conditions, and it cannot control the wastewater filtration speed, resulting in inconvenience during use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a sewage filter device and operating method for hydropower stations, thereby solving the problems mentioned in the background section. The present invention features a novel structure. During use, a lifting mechanism pushes a movable box to the inside of the opening, sealing the opening and controlling the number of openings used to adjust the sewage filtration speed. In addition, the movable box starts a water pump at the sealed opening, driving a movable plate to move. The movable plate moves across the surface of the filter assembly to scrape away impurities, preventing long-term accumulation of impurities that could clog the filter assembly.

[0005] To achieve the above-mentioned technical features, the present invention aims to provide a sewage filter device for a hydropower station, comprising a housing, a power mechanism fixedly installed on the top of the housing, a lifting mechanism fixedly installed on the side of the power mechanism, a fixing hole on the top of the housing, a movable pipe movably installed inside the fixing hole, a water pump fixedly installed on the movable pipe, a connecting hose fixedly installed at one end of the movable pipe, and a groove on the side of the housing, with a support plate fixedly installed inside the groove.

[0006] Preferably, a water inlet pipe is fixedly installed on one side of the box, a drain pipe is fixedly installed on the other side of the box, and a support rod is fixedly installed at the bottom of the box.

[0007] Preferably, a partition plate is fixedly installed inside the box, the partition plate has an opening, a movable box is movably installed inside the opening, and a sealing ring is fixedly installed on the inner wall of the opening, the sealing ring cooperating with the movable box.

The filter assembly includes a fixing frame, a filter plate is fixedly installed inside the fixing frame, a fixing groove is opened on the rotating disk, a limit groove is opened on the inner wall of the fixing groove, and a reset mechanism is fixedly installed inside the limit groove.

[0011] Preferably, a limit block is fixed at one end of the reset mechanism, the limit block has a positioning hole, a positioning column is movably installed inside the positioning hole, and one end of the positioning column is fixed to the bottom of the fixing frame.

[0012] Preferably, one end of the movable box is fixed to the movable tube, a connecting tube is fixedly installed inside the movable box, a horizontal tube is fixed to one end of the connecting tube, and the connecting tube and the horizontal tube are fixedly installed at one end of the movable tube.

[0013] Preferably, a support mechanism is fixedly installed between the connecting pipe and the horizontal pipe. A piston is fixedly installed at one end of the support mechanism. An opening is made in the horizontal pipe. A support column is fixedly installed on one side of the piston. A movable plate is fixedly installed at one end of the support column. One end of the movable plate cooperates with the rotating disk.

[0014] Preferably, a lifting mechanism is fixedly installed at the bottom of the box, a cleaning disc is fixedly installed on the lifting mechanism, the cleaning disc is movably installed inside the box, a slot is opened on the cleaning disc, a top rod is fixedly installed on the side of the slot, and one end of the top rod cooperates with the fixing frame.

[0015] On the other hand, the present invention provides an operation method for a sewage filter device for a hydropower station. In use, a lifting mechanism is used to push a movable box to move into the interior of the opening. The movable box seals the opening, thereby controlling the number of openings used and adjusting the sewage filtration speed. The movable box starts a water pump at the sealed opening to drive the movable plate to move. The movable plate moves on the surface of the filter assembly to scrape off impurities on the filter assembly, avoiding long-term accumulation of impurities that could cause blockage of the filter assembly. The power mechanism drives the rotating disk to rotate at the bottom of the partition plate via the output shaft. The rotation of the rotating disk controls the filter plates with different pore sizes to contact the opening, thereby filtering different types of sewage through different pore sizes. When filtration is not needed, the rotating disk rotates to separate the filter components from the opening. After separation, other positions of the rotating disk block and seal the opening, thereby controlling the opening or closing of sewage filtration. The subsequent lifting mechanism drives the cleaning disc to move up and down inside the housing. The up and down movement of the cleaning disc scrapes against the inner wall of the housing, preventing sewage from adhering to the inner wall and causing problems. In addition, the subsequent cleaning disc pushes the top rod to move upward. The top rod cooperates with the fixing frame to lift the filter plate upward. After the filter assembly moves upward as a whole, it is exposed from inside the opening, and the replacement of the filter assembly is completed.

[0016] The present invention has the following beneficial effects: 1. In use, the present invention uses a lifting mechanism to move the movable box to the inside of the opening, thereby sealing the opening and controlling the number of openings used to adjust the filtration speed of sewage. In addition, the movable box starts the water pump at the opening to drive the movable plate to move. The movable plate moves on the surface of the filter assembly to scrape off impurities on the filter assembly, avoiding the blockage caused by the long-term accumulation of impurities.

[0017] 2. The power mechanism of this invention drives the rotating disk to rotate at the bottom of the partition plate through the output shaft. The rotation of the rotating disk controls the filter plates with different apertures to contact the opening. Different types of sewage are filtered by different filter apertures. In addition, when filtration is not needed, the rotating disk rotates to separate the filter assembly from the opening. After separation, other positions of the rotating disk block and seal the opening, thereby controlling the opening or closing of sewage filtration.

[0018] 3. In the later stage of this invention, the lifting mechanism drives the cleaning disc to move up and down inside the box. The up and down movement of the cleaning disc scrapes against the inner wall of the box, which prevents sewage from adhering to the inner wall of the box and causing problems. In addition, the later stage cleaning disc pushes the top rod to move upward. The top rod cooperates with the fixing frame to lift the filter plate upward. After the filter assembly moves upward as a whole, it is exposed from the inside of the opening. After exposure, the replacement of the filter assembly is completed. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please see Figures 1 to 8 This invention provides a technical solution: a sewage filter device for a hydropower station, comprising a device body, the device body including a housing 1, a power mechanism 6 fixedly installed on the top of the housing 1, a lifting mechanism 7 fixedly installed on the side of the power mechanism 6, a fixing hole on the top of the housing 1, a movable pipe 8 movably installed inside the fixing hole, a water pump 9 fixedly installed on the movable pipe 8, a connecting hose 10 fixedly installed at one end of the movable pipe 8, a groove 4 on the side of the housing 1, a support plate 5 fixedly installed inside the groove 4, and the lifting mechanism 7 being an electric push rod, the electric push rod pushing the movable housing 14 to move up and down, the up and down movement of the movable housing 14 quickly switching the number of openings 13 in use.

[0031] In this embodiment, a water inlet pipe 2 is fixedly installed on one side of the box 1, and a drain pipe 3 is fixedly installed on the other side of the box 1. A support rod 11 is fixedly installed at the bottom of the box 1. A partition plate 12 is fixedly installed inside the box 1. An opening 13 is opened on the partition plate 12. A movable box 14 is movably installed inside the opening 13. A sealing ring 28 is fixedly installed on the inner wall of the opening 13. The sealing ring 28 cooperates with the movable box 14. A movable column 15 is fixedly installed on the top of the movable box 14. One end of the movable column 15 is installed on the lifting mechanism 7. A pipe 25 is fixedly installed on the side of the movable box 14. The pipe 25 facilitates the entry of sewage into the interior of the movable box 14. As the sewage pushes, the movable plate 27 moves inside the horizontal pipe 29, providing assistance for the movement of the movable plate 27.

[0032] In this embodiment, an output shaft 16 is mounted on the power mechanism 6. The output shaft 16 is rotatably mounted on the partition plate 12. A rotating disk 17 is fixedly mounted on one end of the output shaft 16. The rotating disk 17 is rotatably mounted on the bottom of the partition plate 12. A filter assembly 18 is mounted on the rotating disk 17. The filter assembly 18 includes a fixing frame 19. A filter plate 20 is fixedly mounted inside the fixing frame 19. A fixing groove 21 is opened on the rotating disk 17. A limiting groove 31 is opened on the inner wall of the fixing groove 21. A reset mechanism 32 is fixedly mounted inside the limiting groove 31. A limiting block 33 is fixed at one end of the reset mechanism 32. A positioning hole 35 is opened on the limiting block 33. A positioning column 34 is movably mounted inside the positioning hole 35. One end of the positioning column 34 is fixed to the bottom of the fixing frame 19. The filter holes of the filter assembly 18 increase sequentially, and different types of sewage are filtered through the filter plates 20 with different hole diameters.

[0033] In this embodiment, one end of the movable box 14 is fixed to the movable tube 8. A connecting tube 22 is fixedly installed inside the movable box 14. A horizontal tube 29 is fixed to one end of the connecting tube 22. The connecting tube 22 and the horizontal tube 29 are fixedly installed at one end of the movable tube 8. A support mechanism 23 is fixedly installed between the connecting tube 22 and the horizontal tube 29. A piston 24 is fixedly installed at one end of the support mechanism 23. An opening 30 is formed on the horizontal tube 29. A support column 26 is fixedly installed on one side of the piston 24. A movable plate 27 is fixedly installed at one end of the support column 26. One end of the movable plate 27 is engaged with the rotating disk 17. A lifting mechanism 36 is fixedly installed at the bottom of the box 1. A cleaning disk 37 is fixedly installed on the lifting mechanism 36. The cleaning disk 37 is movably installed inside the box 1. A slot 39 is opened on the cleaning disk 37. A top rod 38 is fixedly installed on the side of the slot 39. One end of the top rod 38 is engaged with the fixed frame 19. Both the support mechanism 23 and the reset mechanism 32 are springs. The support mechanism 23 pushes the piston 24 to move. In the later stage, when there is no suction from the water pump 9, the support mechanism 23 pushes the movable plate 27 back into place for use.

[0034] This device receives its internal electrical components from an external power source. When in use, external wastewater enters the tank 1 through the inlet pipe 2. After entering the tank 1, the wastewater falls onto the top of the partition plate 12 and flows downwards through the opening 13. The position of the filter assembly is rotated according to the type of wastewater. When the wastewater contains larger floating particles, it is filtered through the filter assembly 18 with larger pores. The larger pore size of the filter assembly 18 facilitates rapid filtration of the wastewater. When the wastewater contains… When a large amount of silt is present, the power mechanism 6 is activated to move the filter assembly 18 with a suitable aperture to the bottom of the opening 13 at the opposite position. The movable box 14 is then moved upward from the opening 13, simultaneously filtering the wastewater through the openings 13 at both positions. After prolonged filtration, the movable box 14 is pushed into the interior of the opening 13 by the lifting mechanism 7. The sides of the movable box 14 are sealed with the sealing ring 28. After sealing, the water pump 9 is activated to pump water outward. The pumping action generates suction, which drives the piston 24 to move inside the horizontal tube 29. As the piston 24 moves, it supports... The support column 26 drives the movable plate 27 to move. After the movable plate 27 moves, the sewage leaks out at the position of the pipe 25 and enters the sewage through the pipe 25. The sewage flows inside the movable box 14. When it flows, it moves the movable plate 27, and the material scraped off the filter plate 20 moves upward with the sewage. The sewage enters the interior of the horizontal pipe 29 through the opening 30 and flows upward through the gap between the piston 24 and the movable pipe 8. The water pump 9 cleans the impurities inside the opening 13. Later, the lifting mechanism 36 drives the cleaning disc 37 to move up and down inside the box 1. The up and down movement of the cleaning disc 37 affects the box. The inner wall of the filter assembly 1 is scraped to prevent sewage from adhering to the inner wall of the filter assembly 1 and causing problems. In addition, the cleaning disc 37 pushes the top rod 38 upward. The top rod 38 cooperates with the fixing frame to lift the filter plate 20 upward. The filter assembly 18 moves upward through the limiting block 33. The limiting block 33 pushes the fixing frame 19 upward. The top of the fixing frame 19 is exposed from the opening 13 to the inside. The filter plate 20 on the fixing frame 19 is removed and replaced. After replacement, the fixing frame 19 is installed inside the positioning hole 35 through the positioning post 34, which facilitates the long-term use of the filter assembly 18.

[0035] Example 2: A method for operating a sewage filter device for a hydropower station involves using a lifting mechanism 7 to move a movable box 14 into the opening 13 during use. The movable box 14 seals the opening 13, thereby controlling the number of openings 13 in use and adjusting the sewage filtration speed. The movable box 14 starts a water pump at the sealed opening, driving the movable plate 27 to move. The movable plate 27 moves across the surface of the filter assembly to scrape off impurities on the filter assembly 18, preventing impurities from accumulating for a long time and causing blockage to the filter assembly. The power mechanism 6 drives the rotating disk 17 to rotate at the bottom of the partition plate through the output shaft. The rotation of the rotating disk controls the filter plates 20 with different pore sizes to contact the opening. Different types of sewage are filtered by different pore sizes. When filtration is not required, the rotating disk 17 rotates to separate the filter assembly 18 from the opening. After separation, other positions of the rotating disk block and seal the opening, thereby controlling the opening or closing of sewage filtration. The subsequent lifting mechanism 36 drives the cleaning disc 37 to move up and down inside the housing 1. The up and down movement of the cleaning disc 37 scrapes against the inner wall of the housing 1, preventing sewage from adhering to the inner wall of the housing and causing problems. In addition, the subsequent cleaning disc pushes the top rod 38 to move upward. The top rod 38 cooperates with the fixing frame to lift the filter plate upward. After the filter assembly moves upward as a whole, it is exposed from the inside of the opening, and the replacement of the filter assembly is completed.
