Description

Technical Field

[0001] This utility model relates to the field of groundwater pollution control technology, and in particular to a multi-stage filtration device for groundwater pollution control. Background Technology

[0002] Groundwater refers to water that exists in the pores of rocks below the ground surface. In a narrow sense, it refers to water in saturated aquifers below the groundwater level. In the national standard "Hydrogeological Terminology", groundwater refers to gravity water in various forms buried below the earth's surface. If we need to use the groundwater, we must first filter it before it can be used for subsequent industrial production or daily life. Therefore, we need to use corresponding filtration devices.

[0003] When existing groundwater filtration devices filter groundwater, a large amount of impurities in the groundwater adhere to the filter plate, which can easily clog the mesh of the filter plate. This prevents groundwater from passing through the filter plate quickly, reducing the filtration efficiency and affecting the filtration effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage filtration device for groundwater pollution treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage filtration device for groundwater pollution treatment, comprising a filter barrel, a connecting assembly at the top of the inner wall of the filter barrel, three hollow columns outside the connecting assembly, filter plate one, filter plate two, and filter plate three fixedly connected to the outside of the three hollow columns respectively, a rotating assembly on the inner wall of each of the three hollow columns, a sliding assembly between the two sides of the inner wall of each of the three hollow columns, two semi-circular mounting plates one, two semi-circular mounting plates two, and two semi-circular mounting plates three respectively on the three sliding assemblies, a plurality of ejector columns one fixedly connected to the top of each of the two semi-circular mounting plates one, a plurality of ejector columns two fixedly connected to the top of each of the two semi-circular mounting plates two, and a plurality of ejector columns three fixedly connected to the top of each of the two semi-circular mounting plates three, a driving assembly at the bottom of the filter barrel, and a collecting assembly outside the filter barrel.

[0006] By setting up connecting components and driving components, the rotating components can continuously drive the sliding components to move up and down, so that the three sliding components continuously drive the two semi-circular mounting plates one, two semi-circular mounting plates two, and two semi-circular mounting plates three to move up and down. This allows the ejector columns one, two, and three to eject impurities from the mesh holes of filter plates one, two, and three, thus facilitating the cleaning of impurities from the mesh holes of filter plates one, two, and three.

[0007] As a further description of the above technical solution:

[0008] The diameter of the mesh hole in the first filter plate is larger than the diameter of the mesh hole in the second filter plate, and the diameter of the mesh hole in the second filter plate is larger than the diameter of the mesh hole in the third filter plate.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes a connecting rod rotatably connected to the top of the inner wall of the filter barrel. Three bevel gears are sleeved on the outside of the connecting rod. The bottom end of the connecting rod extends through to the bottom of the filter barrel and is fixedly connected to the connecting gear. Three sets of mounting strips are fixedly connected to the outside of the connecting rod. Each of the three sets of mounting strips has two cleaning strips at its bottom.

[0011] By setting up a connecting rod and three sets of mounting strips, when the drive assembly drives the connecting gear to rotate, the connecting gear drives the connecting rod to rotate, which in turn drives the three sets of mounting strips and several cleaning strips to move, thereby pushing the impurities from filter plate one, filter plate two and filter plate three into the collection assembly for collection.

[0012] As a further description of the above technical solution:

[0013] The rotating assembly includes a rotating shaft rotatably connected to the inner wall of the hollow column, one end of the rotating shaft is fixedly connected to a bevel gear, and a drive gear is sleeved on the outside of the rotating shaft.

[0014] As a further description of the above technical solution:

[0015] The sliding assembly includes two limiting rods fixedly connected between the two sides of the inner wall of the hollow column. Each of the two limiting rods is slidably connected to a moving strip. A connecting frame is fixedly connected to one side of the moving strip, and a rack is fixedly connected to the surface of the moving strip.

[0016] By setting two racks, the rotation of the drive gear will cause the two racks to move up and down continuously, which in turn will cause the connecting frame to move up and down, so that the connecting frame can drive the two semi-circular mounting plates one, two semi-circular mounting plates two, and two semi-circular mounting plates three to move up and down.

[0017] As a further description of the above technical solution:

[0018] The drive assembly includes a mounting bracket fixedly connected to the bottom of the filter barrel. A motor is mounted on one side of the mounting bracket. The output end of the motor extends through the interior of the mounting bracket and is fixedly connected to a reciprocating lead screw. A rack is threaded onto the external side of the reciprocating lead screw.

[0020] The collection assembly includes two sets of collection frames fixedly connected to the outside of the filter barrel. Each set of collection frames is provided with several discharge pipes, and valves are installed on the outside of the discharge pipes.

[0021] By setting up a collection box, the impurities that have been cleaned up can be removed.

[0022] As a further description of the above technical solution:

[0034] 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.

[0035] Reference Figure 1-5This utility model provides a multi-stage filtration device for groundwater pollution treatment: It includes a filter tank 1, a connecting assembly at the top of the inner wall of the filter tank 1, three hollow columns 2 outside the connecting assembly, and filter plates 3, 4, and 5 fixedly connected to the outside of the three hollow columns 2 respectively. Rotating assemblies are provided on the inner walls of each of the three hollow columns 2, and sliding assemblies are provided between the two sides of the inner walls of each of the three hollow columns 2. Two semi-circular mounting plates 6, two semi-circular mounting plates 7, and two... Each of the two semicircular mounting plates 3 (8) and 6 (1) has several ejector posts 9 fixedly connected to its top; each of the two semicircular mounting plates 7 (2) has several ejector posts 10 fixedly connected to its top; each of the two semicircular mounting plates 8 (3) has several ejector posts 11 fixedly connected to its top; a drive assembly is provided at the bottom of the filter tank 1; a collection assembly is provided on the outside of the filter tank 1; the diameter of the mesh hole of filter plate 3 (1) is larger than the diameter of the mesh hole of filter plate 4 (2); the diameter of the mesh hole of filter plate 4 (2) is larger than the diameter of the mesh hole of filter plate 5 (3); the diameter of the mesh hole of filter plate 3 (2) is larger than the diameter of the mesh hole of filter plate 5 (3). 4 is located below filter plate 3, filter plate 5 is located below filter plate 4, semi-circular mounting plates 6, 7, and 8 are located below filter plate 3, filter plate 4, and filter plate 5 respectively, several ejector pins 9 are located at one end of the mesh holes on filter plate 3 and directly below the mesh holes, several ejector pins 10 are located at one end of the mesh holes on filter plate 4 and directly below the mesh holes, and several ejector pins 11 are located at one end of the mesh holes on filter plate 5. Located directly below the mesh openings, the rotating component, through the connection and drive components, continuously drives the sliding component to move up and down. This causes the three sliding components to continuously drive the two semi-circular mounting plates 1-6, 2-7, and 3-8 to move up and down, allowing the ejector columns 1-9, 2-10, and 3-11 to eject impurities from the mesh openings of filter plates 1-3, 2-4, and 3-5. This facilitates the cleaning of impurities from the mesh openings of filter plates 1-3, 2-4, and 3-5.

[0036] The connecting assembly includes a connecting rod 12 rotatably connected to the top of the inner wall of the filter barrel 1. Three bevel gears 13 are sleeved on the outside of the connecting rod 12. The bottom end of the connecting rod 12 extends to the bottom of the filter barrel 1 and is fixedly connected to a connecting gear 14. Three sets of mounting strips 15 are fixedly connected to the outside of the connecting rod 12. Each set of mounting strips 15 has two cleaning strips 16 at its bottom. The three bevel gears 13 are located inside the three hollow columns 2. Each set of mounting strips 15 consists of two mounting strips 15, and the three sets of mounting strips 15 are located on filter plate 3, filter plate 4, and filter plate 5, respectively. Above 5, the tops of the two cleaning strips 16 are fixedly connected to the bottoms of the two mounting strips 15 respectively, and the bottoms of several cleaning strips 16 are respectively attached to the surfaces of filter plate 3, filter plate 4 and filter plate 5. By setting the connecting rod 12 and the three sets of mounting strips 15, when the drive assembly drives the connecting gear 14 to rotate, the connecting gear 14 drives the connecting rod 12 to rotate, thereby driving the three sets of mounting strips 15 and several cleaning strips 16 to move, thereby pushing the impurities from filter plate 3, filter plate 4 and filter plate 5 into the collection assembly for collection.

[0037] The rotating assembly includes a rotating shaft 17 rotatably connected to the inner wall of the hollow column 2. One end of the rotating shaft 17 is fixedly connected to a bevel gear 19. A drive gear 18 is sleeved on the outside of the rotating shaft 17. The bevel gear 13 meshes with the bevel gear 19.

[0038] The sliding assembly includes two limiting rods 20 fixedly connected between the two sides of the inner wall of the hollow column 2. Each limiting rod 20 has a sliding strip 21 slidably connected to its outer side. A connecting frame 32 is fixedly connected to one side of each sliding strip 21. A rack 22 is fixedly connected to the surface of the sliding strip 21. One side of the connecting frame 32 extends to the outside of the hollow column 2, and one side of each of the two connecting frames 32 on each hollow column 2 is fixedly connected to the bottom of two semi-circular mounting plates 6, 7, and 8, respectively. The rack 1 meshes with the drive gear 18. By setting two racks 22, when the drive gear 18 rotates, it drives the two racks 22 to move up and down continuously, thereby driving the connecting frame 32 to move up and down. This allows the connecting frame 32 to drive the semi-circular mounting plates 6, 7, and 8 to move up and down continuously.

[0039] The drive assembly includes a mounting bracket 23 fixedly connected to the bottom of the filter barrel 1. A motor 24 is mounted on one side of the mounting bracket 23. The output end of the motor 24 extends into the interior of the mounting bracket 23 and is fixedly connected to a reciprocating screw 25. A rack 26 is threadedly connected to the outside of the reciprocating screw 25. The rack 26 meshes with a connecting gear 14. One side of the rack 26 is slidably connected to one side of the inner wall of the mounting bracket 23.

[0040] The collection assembly includes two sets of collection frames 27 fixedly connected to the outside of the filter bucket 1. Each set of collection frames 27 is provided with several discharge pipes 28. A valve 29 is installed on the outside of the discharge pipe 28. The two sets of collection frames 27 are symmetrical about the center of the cleaning bucket, and each set of collection frames 27 consists of three collection frames 27. The discharge pipe 28 is fixedly connected to one side of the collection frame 27. By setting the collection frames 27, the impurities that have been cleaned can be cleaned.

[0041] The top of the filter barrel 1 is fixedly connected to the feed pipe 30, and the outside of the filter barrel 1 is fixedly connected to the water outlet pipe 31.

[0042] Working principle: When in use, the groundwater to be filtered is poured into the filter bucket 1 through the feed pipe 30. At this time, the groundwater entering the filter bucket 1 first passes through the filter plate 3 for preliminary filtration. Then, the groundwater filtered by the filter plate 3 falls onto the filter plate 4 and is further filtered by the filter plate 4. The groundwater filtered by the filter plate 4 falls onto the filter plate 5 and then flows to the bottom of the inner wall of the filter bucket 1, thereby realizing multi-stage filtration of the filter bucket 1.

[0043] When cleaning of filter plates 3, 4, and 5 is required, motor 24 is started, causing reciprocating screw 25 to rotate. This causes rack 26 to move along the reciprocating screw 25, which in turn drives the meshing connecting gear 14 and connecting rod 12 to rotate synchronously. This, in turn, drives bevel gear 13 to rotate, which in turn drives bevel gear 19 to rotate. Bevel gear 19 then drives rotating shaft 17 and drive gear 18 to rotate synchronously. At this time, the two racks 22 meshing with drive gear 18 will move up and down continuously with the rotation of drive gear 18. This causes the two moving bars 21 to drive the two connecting frames 32 to move up and down along the two limit rods 20, which in turn drives the two semi-circular mounting plates 6 to drive several ejector pins 9 to move up and down continuously. The movement of the filter plate 3 pushes out impurities from the mesh. Similarly, the moving frames of the other two hollow columns 2 drive the two semi-circular mounting plates 7 and 8 to move up and down, which in turn drives the ejector columns 10 and 11 to move, pushing out impurities from the mesh of the filter plates 4 and 5. This facilitates the cleaning of impurities from the mesh of the filter plates 3, 4, and 5. At the same time, the connecting rod 12 drives the mounting strips 15 to rotate, which in turn drives the cleaning strips 16 to rotate. This causes the cleaned impurities to be moved and collected in the collection frames 27 under the action of the cleaning strips 16. After the filtration is completed, simply open the valve 29 to allow the impurities to be discharged through the discharge pipe 28.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
