Description

Technical Field

[0001] This utility model relates to the field of separation tank technology, and in particular to a liquid backwashing separation tank. Background Technology

[0002] Liquid backwashing separators have a wide range of applications across various industries. In the chemical industry, they effectively separate impurities from solid-liquid mixtures produced after reactions, protecting equipment from clogging and wear, ensuring continuous production and stable product quality. Their automatic backwashing function also reduces the frequency of manual cleaning, improving production efficiency. In water treatment, whether for industrial wastewater or municipal water supply, this equipment automatically removes impurities by flushing the filter screen with reverse water flow, maintaining filtration effectiveness.

[0003] In existing liquid backwashing separators, when the filter screen needs to be cleaned, a reverse flow of water is often generated in various ways to discharge the residual impurities on the filter screen from the inlet. As a result, when draining water through the inlet, some impurities may remain in the inlet, which will cause the filter screen to be clogged again during the next use.

[0004] Therefore, to address the issue that impurities cleaned from existing liquid backwash separators may still cause secondary clogging of the filter screen, a liquid backwash separator that solves this problem is needed. Utility Model Content

[0031] Example 1:

[0032] refer to Figures 1-5 A liquid backwashing separator includes a tank body 1. Filter frames 9 are connected to the front and rear ends of the tank body 1 via rotating components. A gear groove is formed at the front end of the tank body 1, and a rack groove is formed on the bottom side of the gear groove. A sliding groove 3 is formed at the right end of the bottom side of the rack groove. A sliding member 4 is slidably connected inside the sliding groove 3, and a rack 17 is fixedly connected to the top side of the sliding member 4. The rack 17 is slidably connected inside the rack groove. A connecting rod 16 is rotatably connected to the front side of the gear groove, and a gear 7 is fixedly connected to the outer wall of the connecting rod 16. Inside the gear groove, the connecting rod 16 is connected to the front rotating assembly. The rotating assembly includes a rotating groove. Two rotating grooves are respectively opened at the front and rear ends inside the tank body 1. A clamping arm 8 is rotatably connected inside the rotating groove. The connecting rod 16 passes through the front side of the front rotating groove and is fixedly connected to the front clamping arm 8. A filter frame 9 is slidably connected to the adjacent side of the two clamping arms 8. A filter 10 is provided inside the filter frame 9. A limit groove is opened on the rear side of the filter frame 9. A frame groove 6 is opened on the top side of the tank body 1. The frame groove 6 is located on the top side of the filter frame 9.

[0033] Specifically, when the filter screen needs backwashing after prolonged use, the sliding member 4 is moved, which in turn moves the rack 17. Since the gear 7 and the rack 17 mesh with each other, moving the sliding member 4 will simultaneously rotate the gear 7, thereby rotating the connecting rod 16 and the front clamping arm 8, and in turn rotating the filter screen frame 9. After the filter screen frame 9 has rotated to the other side, a water source is connected, and the water flow backwashes the filter screen 10, achieving the effect of rotating the filter screen 10. This allows the filter screen 10 to be backwashed when it becomes clogged due to prolonged use, thus cleaning the impurities on the surface of the filter screen 10 and preventing the cleaned impurities from causing secondary clogging. This reduces equipment downtime and improves equipment efficiency.

[0034] Example 2:

[0035] refer to Figures 1-5 The rear side of the tank body 1 is provided with an installation groove, and the left and right sides of the installation groove are provided with fixing grooves. A fixing plate 11 is slidably connected inside the installation groove. A fixing rod 12 is fixedly connected to the front side of the fixing plate 11. The front end of the fixing rod 12 passes through the rear rotating assembly and is located inside the fixing groove. Spring grooves are provided at both ends of the fixing plate 11. Fixing components are provided inside the spring grooves. The fixing components include springs 15. The near ends of the two springs 15 are fixedly connected to the near side of the spring grooves at both ends, and the other ends are fixedly connected to fixing members 13. The far ends of the two fixing members 13 are located inside the two limiting grooves. A through groove is provided at the rear side of the spring groove. The rear sides of the two fixing members 13 pass through the two through grooves and are fixedly connected to pressure plates 14.

[0036] Specifically, in use, first, the filter screen frame 9 is placed between the two clamping arms 8 through the frame groove 6. Then, the two pressure plates 14 are pressed, causing the two fixing parts 13 to move and enter the spring groove, compressing the spring 15. Then, the fixing plate 11 is installed into the mounting groove, and the fixing rod 12 enters the limiting groove to limit the filter screen frame 9. Then, the two pressure plates 14 are released, and the spring 15 is reset, so that the fixing parts 13 enter the limiting groove and fix the fixing plate 11. This achieves the effect of removing and replacing the filter screen 10, so that the filter screen 10 can be replaced when it is damaged. At the same time, the filter screen 10 can be disassembled regularly for inspection and maintenance, thereby improving the overall service life of the equipment.

[0037] Working principle: In use, first, place the filter screen frame 9 between the two clamping arms 8 through the frame groove 6. Then, press the two pressure plates 14 and move the two fixing parts 13 so that the two fixing parts 13 enter the spring groove and compress the spring 15. Then, install the fixing plate 11 into the mounting groove and simultaneously move the fixing rod 12 into the limiting groove to limit the filter screen frame 9. Then, release the two pressure plates 14 to reset the spring 15, so that the fixing parts 13 enter the limiting groove and fix the fixing plate 11. When backwashing is required after the filter screen has been used for a long time, move the sliding part 4 and drive the rack 17 to move. Since the gear 7 and the rack 17 mesh with each other, moving the sliding part 4 will simultaneously drive the gear 7 to rotate, thereby driving the connecting rod 16 and the front clamping arm 8 to rotate, and then driving the filter screen frame 9 to rotate. After the filter screen frame 9 has rotated to the other side, connect the water source to backwash the filter screen 10 through the water flow.

[0038] 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.
