Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy construction, and particularly relates to a water conservancy construction filtering device. Background Technique

[0002] The water conservancy construction filtering device is a device used to remove impurities in water in water conservancy projects. Its design purpose is to effectively filter out floating objects, gravel, sediment and other impurities in water while ensuring smooth water flow, so as to protect the normal operation of the water conservancy system and other equipment.

[0003] The existing filtering devices usually use filter plates to filter sewage. However, with long-term use, a large amount of sediment will adhere to the filter plates, which will not only affect the filtering efficiency of sewage, but also cause blockage in severe cases. It requires staff to replace or clean the filter plates, which not only increases the use cost, but also increases the labor force. Therefore, we propose a water conservancy construction filtering device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a water conservancy construction filtering device. By setting a turning component, specifically when the elliptical roller rotates, the protruding position will push the connecting rod to the left, and the connecting rod drives the filter plate to turn. When the protruding position of the elliptical roller leaves, the elastic piece drives the connecting plate to reset through elasticity, and the connecting rod drives the filter plate to reset. In this way, the filter plate can be continuously turned, so as to clean the stains attached to the filter plate. It does not require staff to clean the filter plate, reduces the labor force and avoids the blockage of the filter plate at the same time, enabling the sewage to be filtered more efficiently. It solves the problem that with long-term use of the existing filtering device, a large amount of sediment will adhere to the filter plate, which will not only affect the filtering efficiency of sewage, but also cause blockage in severe cases, and requires staff to replace or clean the filter plate, which not only increases the use cost, but also increases the labor force.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-6 As shown, the present invention is a water conservancy construction filtering device, including a filter box 1. A top shell 11 is fixedly connected to the top of the filter box 1. A water inlet pipe 2 is arranged on the left side of the top shell 11. The bottom of the water inlet pipe 2 is fixedly connected to the top of the filter box 1. A drain pipe 3 is fixedly connected to the right side of the filter box 1. A slag discharge hopper 12 is fixedly connected to the bottom of the filter box 1. A partition plate 121 is fixedly connected to the top inner wall of the slag discharge hopper 12. A filter plate 13 is arranged inside the filter box 1. A motor 111 is fixedly connected to the front of the top shell 11. A turning assembly 112 is arranged inside the top shell 11;

[0028] The flipping component 112 includes a rotating rod 21. The rotating rod 21 is rotatably connected to the top shell 11. The front of the rotating rod 21 is fixedly connected to the output end of the back of the motor 111. Two elliptical rollers 22 are fixedly connected to the outer surface of the rotating rod 21. Connecting rods 23 are in contact with the left sides of the two elliptical rollers 22. The bottoms of the two connecting rods 23 are fixedly connected to the top of the filter plate 13. A connecting plate 24 is fixedly connected to one side of the two connecting rods 23 corresponding to each other. Two elastic pieces 25 are arranged on the left side of the connecting plate 24. Fixed shafts II 131 are fixedly connected to the upper parts of the front and back of the filter plate 13. Fixed shafts III 132 are fixedly connected to the lower parts of the front and back of the filter plate 13. Fixed blocks II 133 are rotatably connected to the outer surfaces of the two fixed shafts III 132. The bottoms of the two fixed blocks II 133 are fixedly connected to the top of the partition plate 121. By arranging the flipping component 112, specifically when the elliptical roller 22 rotates, the protruding position will push the connecting rod 23 to the left, and the connecting rod 23 drives the filter plate 13 to flip. When the protruding position of the elliptical roller 22 leaves, the elastic piece 25 drives the connecting plate 24 to reset through the elastic action, and the connecting rod 23 drives the filter plate 13 to reset. In this way, the filter plate 13 can be continuously flipped, so as to clean the stains attached to the filter plate 13. It is not necessary for the staff to clean the filter plate 13, which reduces the labor force and avoids the blockage of the filter plate 13 at the same time, enabling the sewage to be filtered more efficiently.

[0029] Fixed shafts I 251 are fixedly connected to both ends of the front and back of the elastic piece 25. Fixed blocks I 252 are rotatably connected to the outer surfaces of the fixed shafts I 251. The bottom of the fixed block I 252 on the left is fixedly connected to the top of the filter box 1. The right side of the fixed block I 252 on the right is fixedly connected to the left side of the connecting plate 24. Since the elastic piece 25 rotates on the fixed block I 252 through the fixed shaft I 251, the elastic piece 25 can be smoothly squeezed, and after being squeezed, the elastic piece 25 has a certain range of movement.

[0030] Two sealing plates 122 are in contact with the bottom of the slag discharge hopper 12. Support plates 123 are fixedly connected to the left and right sides of the slag discharge hopper 12. Hydraulic cylinders 124 are fixedly connected to the sides of the two support plates 123 away from each other. Sealing rings 221 are sleeved on the tops of the sealing plates 122. The front and back of the sealing plates 122 are slidably connected to limiting frames 222. The tops of the two limiting frames 222 are fixedly connected to the bottom of the slag discharge hopper 12. The side of the sealing plate 122 close to the support plate 123 is fixedly connected to the output end of the hydraulic cylinder 124. Starting the hydraulic cylinder 124 drives the sealing plate 122 to move, and the sealing plate 122 slides on the limiting frame 222, thereby opening the opening at the bottom of the slag discharge hopper 12 to discharge the stains.

[0031] A partition plate 14 is fixedly connected to the inner wall of the filtering box 1, and a column 15 is fixedly connected to the bottom of the inner wall of the filtering box 1. A plurality of convex rings 151 are fixedly connected to the outer surface of the column 15. The top of the column 15 is tapered. The column 15 corresponds to the water inlet pipe 2. By providing the partition plate 14 and the column 15, specifically, after the sewage enters the inside of the filtering box 1, it will first contact the column 15, which is used to slow down the sewage and reduce the impact force. By providing the convex rings 151, the sewage can be slowed down again, so that the sewage slowly enters the filtering box 1. The filtered sewage then flows into the right area of the partition plate 14 from the bottom of the partition plate 14, enabling the water flow to slowly enter from the bottom, so it will not affect the clean water flow above.

[0032] Arc-shaped grooves 16 are formed in both the front and back of the inner wall of the filtering box 1, and two sliding grooves 17 are formed in the top of the filtering box 1. The inner wall of the arc-shaped groove 16 contacts the outer surface of the fixed shaft II 131, and the inner wall of the sliding groove 17 contacts the outer surface of the connecting rod 23. When the connecting rod 23 moves, it will slide in the sliding groove 17. When the filter plate 13 moves, the fixed shaft II 131 will slide in the arc-shaped groove 16, which can make the filter plate 13 move more stably.

[0033] An opening is formed at the bottom of the slag discharge hopper 12. The top of the sealing ring 221 contacts the bottom of the slag discharge hopper 12. A flow opening is formed between the bottom of the partition plate 14 and the slag discharge hopper 12. The top of the sealing ring 221 contacts the bottom of the slag discharge hopper 12 to prevent water from overflowing during sewage filtration.

[0034] A specific application of this embodiment is:

[0035] During use, the sewage is transported into the filter tank 1 through the water inlet pipe 2. The sewage will first come into contact with the upright column 15 to slow down the sewage and reduce the impact force. Through the provided convex ring 151, the sewage can be slowed down again, enabling the sewage to slowly enter the filter tank 1. Subsequently, the sewage is filtered by the filter plate 13. The filtered sewage then flows to the right side of the filter plate 13, and the water flow enters the right area of the partition plate 14 from the bottom of the partition plate 14, allowing the water flow to slowly enter from the bottom. Then, the water flow on the right side of the partition plate 14 will settle, and the clean water flow above will be discharged through the drain pipe 3. Since the filtered water flow slowly enters the right side from the bottom of the partition plate 14, it will not affect the clean water flow above. Then, the generated stains will remain in the slag discharge hopper 12. When it is necessary to clean the filter plate 13 after filtration is completed, start the motor 111 to drive the rotating rod 21 to rotate, and the elliptical roller 22 will follow and rotate. When the protruding position of the elliptical roller 22 contacts the connecting rod 23, it will push the connecting rod 23 to the left. The connecting rod 23 will slide in the chute 17. At this time, the connecting plate 24 will squeeze the elastic piece 25 under the action of the fixing block one 252 and the fixing shaft one 251. The connecting rod 23 will drive the top of the filter plate 13 to turn over. The fixing shaft two 131 will slide in the arc-shaped groove 16, and the bottom of the filter plate 13 will rotate in the fixing block two 133 through the fixing shaft three 132. When the protruding position of the elliptical roller 22 leaves the connecting rod 23, the elastic piece 25 drives the connecting plate 24 to reset through its elasticity, and then the connecting rod 23 drives the filter plate 13 to reset. Repeating this process can continuously turn over the filter plate 13, thereby cleaning the stains attached to the filter plate 13 and making the stains fall into the slag discharge hopper 12, eliminating the need for staff to clean the filter plate 13. While reducing labor, it also avoids the blockage of the filter plate 13, enabling the sewage to be filtered more efficiently. Finally, start the hydraulic cylinder 124 to drive the sealing plate 122 to move. The sealing plate 122 will slide on the limit frame 222, thereby opening the opening at the bottom of the slag discharge hopper 12 to discharge the stains. The staff can clean the inside of the filter tank 1 by flushing. After cleaning is completed, start the hydraulic cylinder 124 to drive the sealing plate 122 to reset, sealing the opening at the bottom of the slag discharge hopper 12. The top of the sealing ring 221 will contact the bottom of the slag discharge hopper 12 to prevent water from overflowing during sewage filtration, and then the sewage filtration work can be carried out again.
