Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank anti-clogging technology, and in particular to a magnetically driven self-cleaning sedimentation tank sludge discharge anti-clogging device. Background Technology

[0002] A wastewater sedimentation tank is a device used to treat wastewater. It primarily works by using gravity settling to allow suspended solids and pollutants to settle to the bottom, thus purifying the wastewater. Wastewater sedimentation tanks are typically an important component of water treatment systems, used to remove solid particles and pollutants from wastewater and improve water quality. However, the sludge discharge ports of many sedimentation tanks frequently become clogged due to hardened sludge and fiber entanglement. To solve this problem, the pipe diameter is usually increased or an external agitator is installed.

[0003] Since the above solutions cannot simultaneously meet the requirements of structural compactness, low energy consumption, and complete sealing, resulting in low reliability and high maintenance costs of the sludge discharge system, this application proposes a magnetically driven self-cleaning sedimentation tank sludge discharge anti-clogging device.

[0038] Example

[0039] like Figure 1-4 As shown, the present invention proposes a magnetically driven self-cleaning sedimentation tank sludge discharge and anti-clogging device, including a pretreatment chamber 1. A PLC 2 for control and a sludge discharge valve 3 are provided on the front of the pretreatment chamber 1. An anti-clogging structure 4 for preventing equipment blockage is provided inside the pretreatment chamber 1. A connecting frame 7 is fixedly provided on one side of the pretreatment chamber 1. The connecting frame 7 is L-shaped, and an electric push rod 8 is fixedly provided on one side of the connecting frame 7. The output end of the electric push rod 8 is fixedly provided with a connecting plate 9. The connecting plate 9 has an installation cavity. Two electric push rods 10 are fixedly provided in the installation cavity. The electric push rods 10 can adjust the extension length of the scraper 11 so that it fits against the slope and ensures the quality of pushing the sludge. The output ends of the two electric push rods 10 are fixedly provided with the same scraper 11. The scraper 11 is movably connected to the installation cavity. The scraper 11 can push the sludge and prevent the sludge from adhering to the bottom slope of the pretreatment chamber 1. The bottom of the scraper 11 is provided with a waterproof pressure sensor. The waterproof pressure sensor is used to sense whether the scraper 11 fits against the slope of the pretreatment chamber 1.

[0040] The anti-clogging structure 4 includes a planetary gearbox 401 for adjusting speed and torque. A motor 402 for driving is located on one side of the planetary gearbox 401. Two magnetic drive units for zero-leakage transmission are located on the other side of the planetary gearbox 401, corresponding to the output shafts of the sun gear and planetary carrier. A grid mesh connecting shaft and a cutter head shaft 404 for driving are located on the other side of the two magnetic drive units. A grid mesh body 403 for stripping and limiting, and multiple composite cutters 405 for breaking up the hardened layer and conveying sludge are located at one end and outside of the grid mesh connecting shaft and the cutter head shaft 404, respectively. Each composite cutter 405 has two parts: a front section with 45° serrated blades specifically for breaking up hardened material layers; and a rear section with a 30° spiral guide plate that pushes the broken sludge forward axially. Through the cooperation of these two parts, it can cut and break up materials while simultaneously conveying them away.

[0041] The pretreatment chamber 1 is equipped with a flushing structure 6 for cleaning the grid mesh body 403. The flushing structure 6 includes a water pump 601 for conveying cleaning water, a second motor 602 for driving, and two photoelectric switches 605 for status recognition. The included angle between the two photoelectric switches 605 is 30°. A rotating rod 603 is fixedly installed at the output end of the second motor 602. A water supply pipe 606 is fixedly installed outside the rotating rod 603. Multiple water spray nozzles are installed outside the water supply pipe 606. A baffle 60 is fixedly installed outside the rotating rod 603. 4. A water tank 609 is provided on one side of the water pump 601. The water pump 601 has a flexible conduit 1 608 and a flexible conduit 2 607 at the water pump's suction end and discharge end, respectively. The end of the flexible conduit 1 608 away from the water pump 601 is connected to the side of the water tank 609. The end of the flexible conduit 2 607 away from the water pump 601 is fixedly connected to the connecting nozzle at the top of the water supply pipe 606. After the mud discharge valve 3 is closed, the flushing structure 6 can realize high-pressure water flushing of the grid body 403±30° swing mode for a flushing time of sixty seconds.

[0042] The planetary gearbox 401 is externally equipped with a heat dissipation assembly 5, which includes two mounting plates 501 for positioning. A connecting ring 502 is snapped between the two mounting plates 501. The inner sides of the two mounting plates 501 are provided with slots 504. Two locking blocks 505 are fixedly provided on the outside of the connecting ring 502. The locking blocks 505 and the slots 504 are compatible. The inner wall of the connecting ring 502 is in contact with the planetary gearbox 401. Several heat dissipation fins 503 are fixedly provided on the outside of the connecting ring 502. Both the connecting ring 502 and the heat dissipation fins 503 are made of aluminum. The heat dissipation assembly 5 can improve the heat dissipation performance of the planetary gearbox 401 and reduce the probability of failure due to overheating.

[0043] In operation, the extension and retraction speed and interval of the electric push rod 8 are set via PLC2. Then, motor 402 is started, and sludge is introduced into the pretreatment chamber 1. The electric push rod 8 drives the connecting plate 9, which in turn drives the scraper 11. A waterproof pressure sensor at the bottom of the scraper 11 senses whether it is in contact with the slope of the pretreatment chamber 1. When the scraper 11 is in contact with the slope, the pressure sensor transmits a signal to PLC2, which then shuts off the electric push rod 10. As the scraper 11 moves closer to the rotating rod 603, it separates from the slope. When the PLC2 is activated, the electric push rod 10 will cause its output end to move the scraper 11 downward, so that the bottom of the scraper fits properly against the slope, realizing the conveying of sludge and preventing the sludge from adhering to the slope and being unable to move. The motor 402 provides power to the planetary gearbox 401. The output shaft of the sun gear and the output shaft of the planetary carrier in the planetary gearbox 401 provide power to the two magnetic drive units. The two magnetic drive units then drive the bar screen body 403 and the composite blade 405 respectively, and the rotation speed ratio of the bar screen body 403 and the composite blade 405 is 3:1. The bar screen body 403 can peel fibers from the sludge, and the composite blade 405 can break up the compacted layer and axially push the sludge, realizing the function of crushing and transporting materials. When the sludge discharge valve 3 is closed, PLC2 will start the water pump 601 and motor 602. The water pump 601 introduces water from the water tank 609 into the water supply pipe 606 and sprays it out through the spray nozzle. The motor 602 drives the rotating rod 603, and the rotating rod 603 drives the baffle 604 to rotate. When the baffle 604 blocks one of the photoelectric switches 605, PLC2 receives a signal and causes the motor 602 to rotate in the opposite direction. When the baffle 604 blocks another photoelectric switch 605, PLC2 then causes motor 602 to rotate forward, thereby driving the water spray nozzle to swing ±30° for cleaning. When the planetary gearbox 401 is running, the heat dissipation fins 503 can accelerate the heat dissipation speed of the equipment and improve its heat dissipation performance, thereby reducing the probability of failure due to overheating. The connecting ring 502 can be disassembled and assembled by rotating clockwise and counterclockwise, which is convenient for subsequent replacement and maintenance. After long-term use, the surface impurities of the grid body 403 can be cleaned and maintained by a combination of manual and water rinsing.

[0044] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
