Description

Technical Field

[0001] This invention belongs to the technical field of sewage treatment equipment, and particularly relates to a secondary sedimentation tank cleaning device. Background Technology

[0002] The secondary sedimentation tank is an important component of the activated sludge wastewater treatment system. It is primarily used for solid-liquid separation of the mixed liquor effluent from the aeration tank, clarifying the treated wastewater, and simultaneously concentrating the activated sludge. During long-term operation, sludge, debris, and scale easily accumulate on the tank walls, bottom, and flow guide components. If these deposits are not cleaned promptly, they will reduce the effective volume of the secondary sedimentation tank, affecting solid-liquid separation and lowering wastewater treatment efficiency. Furthermore, the accumulation of deposits can breed bacteria, produce odors, cause secondary pollution, and even clog the bottom pipes, increasing equipment maintenance costs and downtime.

[0003] Existing technologies have the following drawbacks: they require workers to enter the secondary sedimentation tank and use tools such as high-pressure water guns and scrapers for cleaning. This method is not only labor-intensive and inefficient, but also presents safety hazards such as oxygen deficiency and poisoning due to the harsh environment inside the secondary sedimentation tank. Furthermore, manual cleaning makes it difficult to ensure the uniformity and thoroughness of the cleaning. Therefore, we propose a secondary sedimentation tank cleaning device. Summary of the Invention

[0004] The purpose of this invention is to provide a secondary sedimentation tank cleaning device to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a secondary sedimentation tank cleaning device, comprising: A crossbeam has base plates fixedly installed at its bottom and on both sides. Both base plates have wheels installed at their bottoms. A through groove is opened at the top of the crossbeam. A support column is fixedly installed at the top of the crossbeam. A rectangular groove is opened in the support column. A hydraulic cylinder is fixedly installed in the rectangular groove. A water pump is fixedly installed at the top of the crossbeam and on one side of the support column. A hose is fixedly installed at the output end of the water pump. A pusher blade, which is fixedly installed at the output end of a hydraulic cylinder, has several slots on one side. A collection cover, wherein a number of locking blocks are fixedly installed at one end of the collection cover, and a filter screen is fixedly installed inside the collection cover; A cleaning assembly, located on top of a pusher, is used to scrub and clean the bottom of the secondary sedimentation tank.

[0006] In this technical solution, during use, the device is pushed to the top of the secondary sedimentation tank, the hydraulic cylinder and water pump are started, and the output shaft of the hydraulic cylinder drives the pusher to move downwards, embedding it into the sludge layer at the bottom of the secondary sedimentation tank. The water pump delivers water through a hose to the high-pressure nozzle. Personnel push the entire device along the track at the top of the secondary sedimentation tank, causing the sludge to be pushed forward by the pusher. At the same time, the high-pressure nozzle sprays water to flush the bottom of the tank, suspending the sludge in the water. The sludge is then guided through the collection hood into the filter screen for solid-liquid separation. After cleaning, the hydraulic cylinder is started to lift the pusher to the initial position, the water pump is turned off, the collection hood and pusher are disassembled, the filter screen inside the collection hood is removed and residual solid impurities are cleaned, and then the filter screen is reinstalled. This effectively reduces the labor intensity of manual cleaning and also improves the efficiency of the cleaning operation.

[0007] In the above technical solution, the cleaning component further includes: A conveying pipe is fixedly installed on the top of the pusher, and several high-pressure nozzles are fixedly installed on one side of the conveying pipe.

[0008] In this technical solution, the high-pressure nozzles are connected to the delivery pipes, so that the water is pressurized by the water pump and evenly delivered to each high-pressure nozzle, thereby achieving all-round rinsing of the bottom of the secondary sedimentation tank and effectively improving cleaning efficiency and cleanliness.

[0009] In the above technical solution, the filter screen has a precision of 0.05 cm.

[0010] In this technical solution, the filter screen is designed to effectively intercept fine particles in the sludge while allowing water to flow smoothly, thus preventing clogging and ensuring the continuous and efficient operation of the solid-liquid separation process.

[0011] In the above technical solution, the cross-sectional dimensions of the rectangular groove are equal to the cross-sectional dimensions of the hydraulic cylinder.

[0012] In this technical solution, the hydraulic cylinder is ensured to operate stably within the rectangular groove without shaking or jamming, thereby ensuring the smoothness of the pusher during lifting and lowering, and making the operation of the entire cleaning device more reliable.

[0013] In the above technical solution, furthermore, the other end of the hose is connected to the input end of the delivery pipe.

[0014] In this technical solution, the high-pressure water flow output by the water pump is ensured to be smoothly introduced into the delivery pipe through the hose, and then evenly distributed to each high-pressure nozzle to achieve continuous and efficient flushing of the sediment at the bottom of the pool.

[0015] Furthermore, in the above technical solution, the card slot is adapted to the card block.

[0016] This technical solution ensures that the cleaning device will not loosen or fall off during operation, guarantees the reliability of the connection between the pusher and related components, makes the entire cleaning device more stable during operation, and improves the cleaning effect and service life of the device.

[0017] In the above technical solution, the diameter of the hose is equal to the diameter of the input end of the delivery pipe.

[0018] In this technical solution, it is ensured that the high-pressure water flow output by the water pump will not experience pressure loss or water flow turbulence due to diameter differences during transmission, and can enter the delivery pipe with stable and sufficient water pressure, thereby ensuring that each high-pressure nozzle receives a uniform and strong water flow, improving the flushing efficiency and quality of sediment at the bottom of the pool.

[0019] The beneficial effects of this invention are: 1. This secondary sedimentation tank cleaning device, through its locking block and slot cooperation structure, further enhances the connection stability between the pusher and the hydraulic cylinder, effectively preventing displacement or loosening under high-frequency vibration or continuous operation conditions, ensuring continuous and stable cleaning operations. Simultaneously, this structure facilitates disassembly and maintenance, improving the device's operability and ease of repair, and extending the overall service life of the equipment.

[0020] 2. This secondary sedimentation tank cleaning device, through its high-pressure nozzles and delivery pipes, ensures that high-pressure water is evenly sprayed to all areas of the tank bottom, effectively reducing the intensity of manual cleaning and improving cleaning efficiency and cleanliness. Simultaneously, the filter effectively collects sludge particles in the water, preventing sludge from re-entering the water and causing secondary pollution, thus ensuring water quality meets standards.

[0039] Working principle: When in use, push the device to the top of the secondary sedimentation tank, start the hydraulic cylinder 12 and water pump 4. The output shaft of the hydraulic cylinder 12 drives the pusher 10 to move downward, so that it is embedded in the sludge layer at the bottom of the secondary sedimentation tank. The water pump 4 delivers water to the high-pressure nozzle 15 through the hose 7. The personnel push the whole device along the track at the top of the secondary sedimentation tank, so that the sludge is pushed forward by the pusher 10.
