Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sedimentation tank with a graded filtration function. Background Technology
[0002] Wastewater refers to the total amount of water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other non-useful water such as initial rainwater runoff into drainage pipes and ditches. Generally, it refers to water that cannot be recycled after certain technical treatment or water that cannot be purified to meet certain standards after primary pollution. Wastewater sedimentation tanks are used to treat wastewater.
[0003] Chinese Patent Publication No. CN220715126U discloses a multi-layer filtration wastewater sedimentation tank, comprising a main body including a device body, an inlet on the device body, an outlet on the device body, a first barrier wall installed on the device body, and a second barrier wall installed on the device body; and a high-efficiency filtration component including a first filtration tank formed by the first barrier wall and the device body, a second filtration tank formed by the second barrier wall and the first barrier wall, a purified water tank formed by the second barrier wall and the device body, a first filter outlet on the first barrier wall, and a second filter outlet on the second barrier wall. The application describes a wastewater sedimentation tank that, through the coordinated design of its main structure and high-efficiency filtration structure, can perform multiple filtrations during use. This multi-stage filtration improves the quality of the filtered wastewater and reduces filtration time, thus increasing the efficiency of the sedimentation tank. However, in the case of the aforementioned patent, impurities tend to accumulate on the filter plates after prolonged filtration, requiring frequent cleaning. Cleaning can only be done manually by disassembling the filter, which is time-consuming and labor-intensive, reducing the practicality of the device. Therefore, we propose a sedimentation tank with a graded filtration function. Utility Model Content

[0030] This invention provides a sedimentation tank with a graded filtration function, avoiding manual cleaning, reducing labor, saving time, improving cleaning efficiency, and enhancing the practicality of the device. Please refer to [link / reference]. Figure 1-5 It includes a sedimentation tank 100, a drain pipe 200, an inlet pipe 300, a cleaning mechanism 400, and a connecting mechanism 500;
[0031] Please refer to it again. Figure 1 The sedimentation tank 100 is used to install the drain pipe 200, the inlet pipe 300, the cleaning mechanism 400, and the connecting mechanism 500;
[0032] Please refer to it again. Figure 1 The drain pipe 200 is fixed to the top of one side of the sedimentation tank 100, the inlet pipe 300 is fixed to the top of the other side of the sedimentation tank 100, the cleaning mechanism 400 is set on the top of the sedimentation tank 100, and the connecting mechanism 500 is set on both sides of the cleaning mechanism 400.
[0033] Please refer to it again. Figure 2 The bottom of the sedimentation tank 100 is uniformly fixed with partitions 110. The interior of the sedimentation tank 100 is symmetrically provided with slots 120 on both sides and located on top of the partitions 110. The interior of the slots 120 is connected with a filter screen 130. The bottom of one side of the sedimentation tank 100 is uniformly fixed with a drain pipe 140.
[0034] Please refer to it again. Figure 3 The cleaning mechanism 400 includes a mounting frame 410 fixed to the top of the sedimentation tank 100, a drive motor 420 fixed to the top center of the mounting frame 410, and a turntable 430 fixed to the end of the output shaft of the drive motor 420.
[0035] Please refer to it again. Figure 4 A pressing rod 440 is fixed to one side of the turntable 430. A connecting rod 450 slides through the top of the inner side of the mounting bracket 410. A connecting plate 460 is fixed to the bottom of the connecting rod 450. A cleaning brush 470 is fixed to one side of the connecting plate 460 by bolts. A moving plate 480 is fixed to the top of the connecting rod 450. A square groove 481 is opened through the middle of one side of the moving plate 480.
[0036] In summary, when cleaning is required, the drive motor 420 is started, which drives the turntable 430 to rotate, causing the extrusion rod 440 to move in a circular motion, thereby extruding the square groove 481. This causes the moving plate 480 to move up and down reciprocally, which in turn causes the connecting rod 450 to move up and down reciprocally, and the cleaning brush 470 to move up and down reciprocally, cleaning the side of the filter screen 130. This avoids manual cleaning, reduces labor, saves time, improves cleaning efficiency, and enhances the practicality of the device.
[0037] Please refer to it again. Figure 2 The sewage pipe 140 is connected to an external sewage pump. The cleaning mechanism 400 is provided with two sets. The outer wall of the filter screen 130 is provided with a sealing gasket, and the mesh diameter of the filter screen 130 decreases sequentially.
[0038] Please refer to it again. Figure 4 The extrusion rod 440 is located inside the square groove 481, and the outer wall of the extrusion rod 440 is in contact with the inner wall of the square groove 481.
[0039] Please refer to it again. Figure 4 The length of the square groove 481 is greater than the diameter of the turntable 430, and the cleaning brush 470 is attached to one side of the filter screen 130.
[0040] Please refer to it again. Figure 5 The connecting mechanism 500 includes a mounting box 510 fixed to both sides of the mounting bracket 410. An L-shaped plate 520 slides inside the mounting box 510. A locking block 530 is fixed to the end of the L-shaped plate 520. A pull rod 540 is fixed to one side of the L-shaped plate 520. A return spring 550 is fixed to the other side of the L-shaped plate 520. A sliding rod 560 is fixed in the middle between the two sides inside the mounting box 510. The top of both sides of the filter screen 130 is provided with a slot 570.
[0041] Please refer to it again. Figure 5 The top of the card block 530 is provided with a slope, and the L-shaped plate 520 slides on the outer wall of the slide rod 560.
[0042] Please refer to it again. Figure 5 One end of the return spring 550 is fixed to the inside side of the mounting box 510, and the return spring 550 is sleeved on the outside of the slide bar 560.
[0043] In summary, when the filter 130 needs to be replaced, pull the lever 540 to move the L-shaped plate 520, causing the locking block 530 to move out of the slot 570, releasing the filter 130 from its fixation, and then removing the filter 130. A new filter 130 is then installed by inserting it into the slot 120. The inclined surface of the locking block 530 is pressed, causing the locking block 530 to move the L-shaped plate 520, pressing the return spring 550. When the locking block 530 aligns with the slot 570, the return spring 550 resets the locking block 530, embedding it into the slot 570 and completing the fixation. This completes the replacement process, making filter replacement simpler, more convenient, time-saving, and improving the device's usability.
[0044] In practical use, when performing graded filtration, wastewater is discharged from the inlet pipe 300 into the sedimentation tank 100 and filtered through multiple filter screens 130. When large impurities accumulate on the surface of the filter screens 130, the drive motor 420 is activated, driving the turntable 430 to rotate, causing the extrusion rod 440 to move circumferentially, thereby extruding the square groove 481. This causes the moving plate 480 to move up and down reciprocally, which in turn causes the connecting rod 450 to move up and down reciprocally, and the cleaning brush 470 to move up and down reciprocally, cleaning one side of the filter screens 130, avoiding the need for manual cleaning. When filter 130 needs to be replaced, pull rod 540 moves L-shaped plate 520, causing block 530 to move out of slot 570, releasing the filter 130 from its fixation, and then disassembling the filter 130. A new filter 130 is then installed by inserting it into slot 120. The inclined surface of block 530 is pressed, causing block 530 to move L-shaped plate 520, pressing the return spring 550. When block 530 aligns with slot 570, the return spring 550 resets block 530, causing it to embed into slot 570, thus completing the replacement.
