Description

Technical Field

[0001] This invention relates to the field of filter technology, and more specifically, to a nuclear-grade main pump seal water return filter for nuclear power plants. Background Technology

[0002] Filters are an indispensable device in pipelines transporting media, typically installed at the inlet end of pressure reducing valves, pressure relief valves, level control valves, and other equipment. A filter consists of a cylinder, a stainless steel filter screen, a drain section, a transmission device, and an electrical control system. When water passes through the filter cylinder, impurities are blocked. Cleaning is simple: just remove the removable filter cylinder, clean it, and reinstall it. Therefore, use and maintenance are extremely convenient.

[0003] Existing technologies disclose some patent documents for water pump filters. Chinese patent application number CN201821489758.6 discloses a vertical water pump filter, including a filter body. An inlet pipe and an outlet pipe are fixedly installed at the left and right ends of the filter body, respectively. A sealing gasket is fixedly installed on the lower right side of the inlet pipe. A fixing cover is fixedly installed on the upper surface of the filter body by fixing bolts. A filter cup is fixedly installed on the lower surface of the fixing cover. A vertical groove is opened on the lower left wall of the filter cup. An inlet is opened in the middle of the left wall of the fixing cover. A first magnetic block is fixedly installed at the top of the inner cavity of the inlet. A placement groove is opened on the lower surface of the filter cup. A second magnetic block is inserted into the inner cavity of the placement groove. This improves the sealing between the inlet pipe and the inlet, preventing the inlet pipe from detaching from the left end of the inlet, which would cause water in the inner cavity of the inlet pipe to flow directly into the inner cavity of the filter body, reducing the filtration effect of the filter cup.

[0004] In the aforementioned patent, it is inconvenient to clean the debris on the filter screen when disassembling the filter, resulting in low cleaning efficiency of the filter screen. To address this, we propose a nuclear-grade main pump sealing water return filter specifically for nuclear power plants. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this invention is to provide a nuclear-grade main pump sealing water return filter specifically for nuclear power plants.

[0025] 3. Beneficial effects

[0026] Compared with the prior art, the advantages of this invention are:

[0027] (1) In this solution, when disassembling and cleaning the filter screen, firstly, the rotating plate is removed from the inner wall of the outer shell. Then, the rotating plate rotates downwards by 90 degrees under gravity. After rotating 90 degrees, the rotating plate fits into the filter screen. At this time, the rotating plate is moved through the screw and connected to the filter screen by the screw thread. The filter screen and the rotating plate are fixed together by the screw. Then, the filter screen is removed from the support plate. Then, the stud is held and the stud is threaded into the threaded hole. After the stud is fixed, the stud is held and pulled to the right. The movement of the stud pulls the rotating plate and the filter screen to the right at the same time. The movement of the rotating plate drives the first gear and the first rotating rod to move. The movement of the first gear causes the first gear to roll at the bottom of the first rack. When the first gear rotates, it drives the first rotating rod and the second gear to rotate. The rotation of the second gear drives the third gear to rotate. The rotation of the third gear drives the second rotating rod to rotate. The rotation of the second rotating rod... Simultaneously, it drives the two crown gears to rotate. The rotation of the crown gears drives the fourth gear and the rotating shaft to rotate. The rotation of the fourth gear drives the fifth gear to rotate. The rotation of the fifth gear drives the reciprocating screw to rotate. The rotation of the reciprocating screw causes the nut to move up and down on the surface of the reciprocating screw. The reciprocating movement of the nut drives the mounting plate to move back and forth. The reciprocating movement of the mounting plate drives the third rotating rod to move up and down. When the third rotating rod moves up and down, it drives the transmission gear to move. Since the transmission gear meshes with the second rack, the transmission gear rotates when it moves up and down. The rotation of the transmission gear drives the third rotating rod to rotate. The rotation of the third rotating rod drives the cleaning roller to rotate. The cleaning roller repeatedly cleans the debris on the surface of the filter screen when it moves up and down, thus facilitating the removal of the filter screen from the housing and cleaning the debris on the surface of the filter screen at the same time, optimizing the convenience of cleaning the filter screen.

[0028] (2) In this scheme, the sliding sleeve is fixed to facilitate sliding cooperation with the guide plate. The sliding cooperation between the sliding sleeve and the guide plate facilitates the stable movement of the nut.

[0029] (3) In this scheme, the first sealing plate is detachably connected to the two second mounting slots, and the second sealing plate is detachably connected to the two third mounting slots. The first sealing plate is for sealing the two second mounting slots, and the second sealing plate is for sealing the third mounting slots.

[0030] (4) In this solution, the filter screen and the rotating plate are detachably connected by screws so that the filter screen can be pulled when the rotating plate is pulled by the stud. The rotating plate is detachably connected to the top of the housing by screws so that when the water is filtered by the filter screen, the rotating plate rotates to the top of the housing and is fixed, so that the filter screen will not be blocked by the rotating plate when filtering water.

[0031] (5) In this scheme, two threaded holes are opened on the right end of the rotating plate. Both threaded holes are threaded with studs. The threaded holes are opened to facilitate the threaded connection with the studs. When filtering water through the filter screen, the studs are removed and taken out from the outer shell so that the filter screen can be pulled by the studs when the filter screen is removed.

The present invention uses the cleaning roller 35 to repeatedly clean the debris on the surface of the filter screen plate 4 by moving up and down and rotating, thereby facilitating the cleaning of the filter screen plate 4 while removing it from the outer casing 1, thus optimizing the convenience of cleaning the filter screen plate 4.

[0053] Specifically, the cleaning mechanism includes a second mounting slot 10, a third mounting slot 11, a sliding hole 14, a rotating component, a linkage component, a reciprocating component, and a cleaning component. There are two of each of the second mounting slot 10, the third mounting slot 11, and the sliding hole 14. Both the second mounting slot 10 and the third mounting slot 11 are located at the right end of the rotating plate 8. The two sliding holes 14 are located in the two third mounting slots 11 respectively. The rotating component, the linkage component, the reciprocating component, and the cleaning component are all mounted on the rotating plate 8. The rotating component is connected to the linkage component, the linkage component is connected to the reciprocating component, and the reciprocating component is connected to the cleaning component.

[0054] In this embodiment, the second mounting slot 10 is opened to facilitate the accommodation of the linkage component, the third mounting slot 11 is opened to facilitate the accommodation of the reciprocating component and the cleaning component, and the sliding hole 14 is opened to facilitate the sliding of the third rotating rod 29. The rotating component, the linkage component, the reciprocating component and the cleaning component are all set on the rotating plate 8. The rotating component and the linkage component are connected, the linkage component and the reciprocating component are connected, and the reciprocating component and the cleaning component are connected.

[0055] Specifically, the rotating assembly includes a first rack 17, a first gear 18, a second gear 19, a second rotating rod 20, and a third gear 21. The first rack 17 is fixedly connected to the upper inner wall of the outer casing 1. The first gear 18 is fixedly connected to the surface of the first rotating rod 7 and meshes with the first rack 17. The second gear 19 is fixedly connected to the surface of the first rotating rod 7. The second rotating rod 20 is rotatably connected to two second mounting slots 10 and moves through the rotating plate 8. The third gear 21 is fixedly connected to the surface of the second rotating rod 20 and meshes with the second gear 19.

[0056] In this embodiment, the movement of the rotating plate 8 drives the first gear 18 and the first rotating rod 7 to move. The movement of the first gear 18 causes the first gear 18 to roll at the bottom of the first rack 17. When the first gear 18 rotates, it drives the first rotating rod 7 and the second gear 19 to rotate. The rotation of the second gear 19 drives the third gear 21 to rotate. The rotation of the third gear 21 drives the second rotating rod 20 to rotate. The rotation of the second rotating rod 20 simultaneously drives the two crown gears 22 to rotate.

[0057] Specifically, the reciprocating assembly is configured in two sets. Each set of reciprocating assemblies includes a reciprocating lead screw 25, a nut 27, a sliding sleeve 31, and a guide plate 32. The reciprocating lead screw 25 is rotatably connected to the third mounting groove 11, and the upper end of the reciprocating lead screw 25 moves through the third mounting groove 11. The nut 27 is threadedly connected to the surface of the reciprocating lead screw 25. The sliding sleeve 31 is fixedly connected to the side end of the nut 27. The guide plate 32 is fixedly connected to the third mounting groove 11, and the guide plate 32 and the sliding sleeve 31 are in sliding engagement.

[0058] In this embodiment, the rotation of the reciprocating screw 25 causes the nut 27 to move up and down on the surface of the reciprocating screw 25. The reciprocating movement of the nut 27 drives the mounting plate 28 to move back and forth. The fixed sliding sleeve 31 is for easy sliding engagement with the guide plate 32. The sliding engagement between the sliding sleeve 31 and the guide plate 32 facilitates the stable movement of the nut 27.

[0059] Specifically, the linkage components are set into two groups. Each group of linkage components includes a crown gear 22, a rotating shaft 23, a fourth gear 24, and a fifth gear 26. The crown gear 22 is fixedly connected to the surface of the second rotating rod 20. The rotating shaft 23 is rotatably connected to the second mounting groove 10. The fourth gear 24 is fixedly connected to the surface of the rotating shaft 23 and meshes with the crown gear 22. The fifth gear 26 is fixedly connected to the surface of the reciprocating lead screw 25 and meshes with the fourth gear 24.

[0060] In this embodiment, the linkage components all include a crown gear 22, a rotating shaft 23, a fourth gear 24, and a fifth gear 26. The crown gear 22 is fixedly connected to the surface of the second rotating rod 20, the rotating shaft 23 is rotatably connected to the second mounting groove 10, the fourth gear 24 is fixedly connected to the surface of the rotating shaft 23 and meshes with the crown gear 22, and the fifth gear 26 is fixedly connected to the surface of the reciprocating screw 25 and meshes with the fourth gear 24. The rotation of the crown gear 22 drives the fourth gear 24 and the rotating shaft 23 to rotate, the rotation of the fourth gear 24 drives the fifth gear 26 to rotate, and the rotation of the fifth gear 26 drives the reciprocating screw 25 to rotate.

[0061] Specifically, the cleaning assembly includes a mounting plate 28, a third rotating rod 29, a transmission gear 30, and a second rack 34. Two mounting plates 28, two transmission gears 30, and two racks 34 are each provided. The two mounting plates 28 are respectively fixedly connected to the adjacent ends of two nuts 27. The third rotating rod 29 is rotatably connected between the two mounting plates 28 and slidably connected within two sliding holes 14. The two transmission gears 30 are both fixedly connected to the surface of the third rotating rod 29. The two second racks 34 are respectively fixedly connected within two third mounting grooves 11, and the two second racks 34 mesh with the transmission gears 30 respectively.

[0062] In this embodiment, the reciprocating movement of the nut 27 drives the mounting plate 28 to reciprocate. The reciprocating movement of the mounting plate 28 drives the third rotating rod 29 to reciprocate up and down. When the third rotating rod 29 reciprocates up and down, it drives the transmission gear 30 to move. Since the transmission gear 30 meshes with the second rack 34, the transmission gear 30 will rotate when it reciprocates up and down. The rotation of the transmission gear 30 drives the third rotating rod 29 to rotate, and the rotation of the third rotating rod 29 drives the cleaning roller 35 to rotate. When the cleaning roller 35 reciprocates up and down, it repeatedly cleans the debris on the surface of the filter screen plate 4.

[0063] Specifically, a first sealing plate 12 is detachably connected to each of the two second mounting slots 10, and a second sealing plate 33 is detachably connected to each of the two third mounting slots 11.

[0064] In this embodiment, a first sealing plate 12 is detachably connected to each of the two second mounting slots 10, and a second sealing plate 33 is detachably connected to each of the two third mounting slots 11. The first sealing plate 12 is for sealing the two second mounting slots 10, and the second sealing plate 33 is for sealing the third mounting slots 11.

[0065] Specifically, the filter screen 4 and the rotating plate 8 are detachably connected by screws 13, and the rotating plate 8 is detachably connected to the top of the housing 1 by screws 13.

[0066] In this embodiment, the filter screen plate 4 and the rotating plate 8 are detachably connected by screws 13 so that the filter screen plate 4 can be pulled when the rotating plate 8 is pulled by the studs 16. The rotating plate 8 is detachably connected to the top of the housing 1 by screws 13 so that when the filter screen plate 4 filters water, the rotating plate 8 rotates to the top of the housing 1 and is fixed, so that the filter screen plate 4 will not be blocked by the rotating plate 8 when filtering water.

[0067] Specifically, the right end of the rotating plate 8 has two threaded holes 15, and studs 16 are threaded into both threaded holes 15.

[0068] In this embodiment, two threaded holes 15 are provided on the right end of the rotating plate 8. A stud 16 is threaded into each of the two threaded holes 15. The threaded holes 15 are provided to facilitate threaded connection with the stud 16. When filtering water through the filter screen plate 4, the stud 16 is removed and taken out from the outer casing 1 so that the filter screen plate 4 can be pulled by the stud 16 when it is disassembled.

[0069] Specifically, four connectors 3 are fixedly connected to the surface of the outer shell 1, and the four connectors 3 are evenly distributed.

[0070] In this embodiment, four connectors 3 are fixedly connected to the surface of the outer shell 1, and the four connectors 3 are evenly distributed. The outer shell 1 can be installed at the outlet of the water pump by means of multiple connectors 3 and bolts, thereby facilitating water filtration.

[0071] Working principle: When disassembling and cleaning the filter screen 4, first remove the rotating plate 8 from the inner wall of the outer casing 1. Then, the rotating plate 8 rotates downwards by 90 degrees under gravity. After rotating 90 degrees, the rotating plate 8 fits against the filter screen 4. At this time, the screw 13 passes through the rotating plate 8 and is threaded into the filter screen 4. The filter screen 4 and the rotating plate 8 are fixed together by the screw 13. Then, remove the filter screen 4 from the support plate 2. Then, hold the stud 16 and thread it into the threaded hole 15. When the stud 16 is fixed... Once finished, hold the stud 16 and pull it to the right. The movement of the stud 16 pulls the rotating plate 8 and the filter screen plate 4 to the right simultaneously. The movement of the rotating plate 8 drives the first gear 18 and the first rotating rod 7 to move. The movement of the first gear 18 causes the first gear 18 to roll at the bottom of the first rack 17. When the first gear 18 rotates, it drives the first rotating rod 7 and the second gear 19 to rotate. The rotation of the second gear 19 drives the third gear 21 to rotate. The rotation of the third gear 21 drives the second rotating rod 20 to rotate. The rotation of the second rotating rod 20... Simultaneously, the two crown gears 22 rotate, which in turn drives the fourth gear 24 and the rotating shaft 23 to rotate. The rotation of the fourth gear 24 drives the fifth gear 26 to rotate, which in turn drives the reciprocating screw 25 to rotate. The rotation of the reciprocating screw 25 causes the nut 27 to move up and down on its surface. The reciprocating movement of the nut 27 drives the mounting plate 28 to move back and forth, which in turn drives the third rotating rod 29 to move up and down. The up and down movement of the third rotating rod 29 drives the transmission... As gear 30 moves, it rotates when it reciprocates up and down because it meshes with the second rack 34. The rotation of gear 30 drives the third rotating rod 29 to rotate, which in turn drives the cleaning roller 35 to rotate. The cleaning roller 35 repeatedly cleans the debris on the surface of the filter screen 4 as it reciprocates up and down, making it easier to clean the surface of the filter screen 4 while removing it from the housing 1. This improves the convenience of cleaning the filter screen 4.

[0072] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
