Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, and in particular to a filter structure for wastewater purification treatment. Background Technology

[0002] With the acceleration of industrialization and the improvement of urbanization, sewage treatment has become an important part of protecting water resources and maintaining ecological balance. Among many advanced sewage treatment technologies, fiber disc filters stand out for their high efficiency, energy saving and easy maintenance. Through a precisely designed fiber disc structure, this filter can efficiently intercept suspended solids, colloids and some dissolved organic matter, significantly improving the quality of effluent.

[0003] A fiber disc filter, as disclosed in utility model patent application CN207786072U, "includes a filter tank, an inlet pipe, and an outlet pipe. The filter tank contains a wastewater tank and a clear water tank formed by vertically arranged partitions. A central pipe is horizontally arranged within the wastewater tank, connected via a bearing seat to a drive device that moves the central pipe up and down. One end of the central pipe is connected to a motor via a rotating shaft, and the other end extends through the partitions into the clear water tank. The partitions have through holes for the central pipe to pass through and allow it to move up and down. A sealing plate is fixed to the central pipe, maintaining contact with the partitions and sealing the through holes. A fiber disc is fitted over the central pipe. Multiple reverse suction discs are vertically installed within the wastewater tank, with gaps between adjacent reverse suction discs to accommodate the fiber discs. This allows the fiber discs to extend into the gaps when the central pipe moves down and extend out of the gaps when the central pipe moves up. This utility model solves the problem of poor filtration effect and low filtration efficiency in existing fiber disc filters caused by the reverse suction discs obstructing the filter cloth."

[0004] However, when the above-mentioned device is in use, by setting a compression spring at the end of the central tube, the sealing plate can be in close contact with the partition when the central tube moves up and down. The compression spring is immersed in the clear water pool for a long time, which can easily rust and weaken the elasticity, reduce the sealing performance, and allow sewage to seep into the clear water pool through the gaps, affecting the water quality.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1:

[0024] like Figure 4-6As shown, a filtration structure for wastewater purification includes a filter tank 1. Mounting plates 4 are fixedly installed on both the front end and the inner wall of the filter tank 1. One side of one set of mounting plates 4 has two sets of guide grooves 17. Guide sliders 22 are slidably engaged with the inner walls of both sets of guide grooves 17. A first square plate 20 is fixedly installed on one side of the guide slider 22. Two connecting plates 14 are fixedly installed on one side of the first square plate 20. Limiting grooves 19 are opened on the top of both sets of connecting plates 14. A rack 5 is slidably engaged with the inner wall of the limiting groove 19. A second square plate 24 is fixedly installed at the tail end of the rack 5. The second square plate 24 is slidably connected to the other side of the mounting plate 4. The top of both sets of connecting plates 14 is rotatably connected to gears 2. The top of both sets of connecting plates 14 is provided with a second drive motor 16. The output end of the second drive motor 16 is fixedly connected to the top of gear 2. The filter tank 1 is provided with a central tube 21. The central tube 21 is fixedly connected to the first square plate 20. One side of one of the two sets of mounting plates 4 is provided with a movable window 23. The second square plate 24 is movably connected to the central tube 21. The facing surfaces of the first square plate 20 and the second square plate 24 are provided with rubber layers.

[0025] By opening a movable window 23 on the mounting plate 4 located on the inner wall of the filter tank 1, and ensuring that the movable window 23 is large enough to accommodate the front end of the central tube 21 and the two sets of connecting plates 14, the front end of the central tube 21 can move flexibly up and down within the movable window 23 when the lifting assembly raises and lowers the central tube 21. The front end of the central tube 21 is equipped with a first square plate 20 and a second square plate 24, which, when the central tube 21 moves up and down, can move the first square plate 20 and the second square plate 24, thereby blocking the sewage in the sewage tank and preventing sewage from entering the clear water tank through the movable window 23. Furthermore, by setting a guide slider 22 and a guide chute... 17. It can indirectly control the central tube 21 to prevent it from rising too high or falling too low, thus preventing the movable window 23 from being opened. When the first square plate 20 and the second square plate 24 slide up and down for a long time and are worn after rubbing against the mounting plate 4, causing gaps to form between the two sets of square plates and the movable window 23, the second drive motor 16 is powered on, causing its output end to drive the gear 2 to rotate. The gear 2 meshes with the rack 5, which in turn causes the rack 5 to slide along the track of the limit slide groove 19, thereby driving the second square plate 24 to move closer to the mounting plate 4 and press it tightly again, thus maintaining the sealing of the equipment and preventing sewage from seeping into the clear water tank through the gaps, ensuring normal water quality.

[0026] like Figure 1 and Figure 2As shown, a filtration structure for wastewater purification includes a first square plate 20 slidably connected to one side of a set of mounting plates 4. Hydraulic rods 8 are fixedly installed on the inner walls of the front ends of both sets of mounting plates 4, providing power for the lifting and lowering of the central tube 21. A first drive motor 3 is fixedly installed at the front end of the hydraulic rod 8, and a first sprocket 7 is fixedly connected to the output end of the first drive motor 3. Multiple sets of turntables 12 are fitted onto the outer surface of the central tube 21, with filter cloths on the turntables 12. The filter cloths, being made of hydrophobic material, effectively block suspended solids and impurities. Water filtered through the filter cloths enters the central tube and is then fed into a clear water tank. Second sprockets 10 are fixedly installed on the outer surfaces of both the front and rear ends of the central tube 21. The inner wall of the filtration tank 1 is fixedly equipped with... The device is equipped with multiple sets of reverse suction cup assemblies 18, and the gap between each pair of reverse suction cup assemblies 18 facilitates the insertion of the turntable 12. When filtration is required, the central tube 21 is raised, which will cause the turntable 12 to disengage from the reverse suction cup assemblies 18, thereby allowing the filter cloth that was blocked by the reverse suction cup assemblies 18 to be exposed, thus accelerating the filtration speed. When backwashing is performed, the central tube 21 is lowered to its original position, which will allow the turntable 12 to be positioned between the two sets of reverse suction cup assemblies 18, so as to remove impurities from the filter cloth. The front end of the first drive motor 3 is provided with a chain 6, and the inner wall of the chain 6 is rotatably connected to the outer surface of the first sprocket 7 and the second sprocket 10. By setting the chain 6 and engaging with the first sprocket 7 and the second sprocket 10 respectively, the purpose of driving the central tube 21 to rise and fall is achieved, and the effect of rotating the central tube 21 is also achieved.

[0027] like Figure 1 and Figure 2 As shown, a filtration structure for wastewater purification is provided. Two sets of support plates 15 are fixedly installed on the bottom wall of the filter tank 1. The top of the support plate 15 is provided with an arc-shaped groove that matches the central tube 21. The support plate 15 provides support for the central tube 21 so that it can rotate normally. A slag discharge suction pipe 13 is fixedly installed on the bottom wall of the filter tank 1. A slag discharge main pipe 9 is fixedly installed on the front of the filter tank 1. The back suction cup assembly 18 is connected to the slag discharge main pipe 9 through a hose. Multiple sets of slag discharge pumps 11 are fixedly installed on the outer surface of the slag discharge main pipe 9. The tail end of the slag discharge suction pipe 13 extends to the outside of the filter tank 1 and is connected to the slag discharge main pipe 9. The slag discharge pumps 11 and the slag discharge main pipe 9 are used to discharge impurities outside the tank during backwashing.

[0028] It should be noted that this utility model is a filtration structure for sewage purification. In use, sewage is input through the inlet of the filter tank 1. The hydraulic rod 8 is controlled to operate, causing the first drive motor 3 to rise. Under the action of the chain 6, the central tube 21 rises. Simultaneously, the central tube 21 moves the first square plate 20 and the second square plate 24, thereby blocking the movable window 23. After being filtered by the filter cloth on the turntable 12, the sewage enters the interior of the central tube 21 and is then input into the clear water tank through the outlet of the central tube 21. The rise of the central tube 21 causes the filter cloth, which was blocked by the back suction cup assembly 18, to leak out, thus accelerating the filtration speed. When backwashing is required, the hydraulic rod 8 is controlled to lower the central tube 21 to the support. The arc-shaped groove at the top of plate 15 positions the turntable 12 between the two sets of reverse suction cup assemblies 18. At the same time, the central tube 21 drives the first square plate 20 and the second square plate 24 to slide downwards, continuing to block the movable window 23. The slag discharge pump 11 is controlled to operate, and the first drive motor 3 is controlled to drive the central tube 21 to rotate, so that the impurities on the filter cloth and the impurities at the bottom of the pool are sucked away and discharged outside the pool. When the first square plate 20 and the second square plate 24 are repeatedly rubbed up and down and become damaged, and gaps are formed between them and the mounting plate 4, the second drive motor 16 is powered on. Then, under the linkage of gear 2 and rack 5, the second square plate 24 is moved horizontally closer to the mounting plate 4 until it is pressed against the mounting plate 4 again, thereby maintaining the sealing of the equipment and preventing sewage from seeping into the clear water pool through the gaps.
