Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, and more specifically to a device for cleaning sludge on the water surface of a sedimentation tank. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water. It is a water purifier that uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter from water. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank.

[0003] After a long period of use, some sludge will float on the surface of the sedimentation tank. This floating sludge will block the pipes and reduce the effective volume of the sedimentation tank itself, thereby reducing the sedimentation effect of the sedimentation tank, and ultimately causing the effluent water quality to fail to meet national environmental protection standards. At the same time, this floating sludge may contain harmful substances such as E. coli. If it enters the body of on-site staff, it will be harmful to the health of the staff. Therefore, we provide a sedimentation tank water surface sludge cleaning device. Utility Model Content

[0023] After a long period of use, some sludge will float on the water surface of the sedimentation tank. This floating sludge will block the pipes and reduce the effective volume of the sedimentation tank itself, thereby reducing the sedimentation effect of the sedimentation tank, and ultimately causing the effluent quality to fail to meet national environmental protection standards. At the same time, this floating sludge may contain harmful substances such as E. coli. If it enters the body of on-site staff, it will harm the health of the staff. The following solution can be used to solve this problem.

The sliding rod 8 is fixedly connected to the nozzle 5. A movable ring 9 is sleeved on the outside of the rotating shaft 3. The movable ring 9 is fixedly connected to the lifting plate 6.

A spring 14 is provided between the clamping block 13 and the mounting groove 12. A clamping groove 15 is provided inside the sleeve 2, and the clamping groove 15 is used in conjunction with the clamping block 13. The elastic force of the spring 14 makes the clamping block 13 always engage with the clamping groove 15. When the rotating shaft 3 rotates forward, the rotating shaft 3 rotates alone. When the rotating shaft 3 rotates reversely, the rotating shaft 3 drives the sleeve 2 to rotate together through the clamping block 13 and the clamping groove 15. The clamping block 13 and the clamping groove 15 play the role of a ratchet pawl.

[0026] Limiting grooves 16 are provided on the corresponding two side edges of the lifting plate 6, and the limiting grooves 16 are internally slidably connected to limiting blocks 17, and the limiting blocks 17 are fixedly connected to the fixing frame 4. The lifting plate 6 is limited by the limiting grooves 16 and the limiting blocks 17 so that the lifting plate 6 can only move up and down.

[0027] A motor 18 is fixedly connected to the bottom of the mounting frame 1, a first gear 19 is fixedly connected to the output end of the motor 18, a second gear 20 is fixedly connected to the outside of the rotating shaft 3, the second gear 20 is meshed with the first gear 19, and the motor 18 starts to drive the first gear 19 to rotate, and the first gear 19 drives the rotating shaft 3 to rotate through the second gear 20.

[0028] A first pipeline 21 is arranged inside the rotating shaft 3. The rotating shaft 3 is a hollow structure. The first pipeline 21 passes through the rotating shaft 3 and extends to the bottom. The first pipeline 21 and the nozzle 5 are connected by a second pipeline 22. The user can connect the first pipeline 21 with a high-pressure water pump or a high-pressure air pump as needed, and transport the high-pressure water or high-pressure air to the nozzle 5 and spray it out through the first pipeline 21 and the second pipeline 22.

One end of the second pipeline 22 is connected to the first pipeline 21, and the other end of the second pipeline 22 is connected to the nozzle 5.

[0029] The slide groove 10 is a wave-shaped structure. When the shaft 3 rotates, the slide groove 10 with the wave-shaped structure will squeeze the slider 11 inside the movable ring 9 through the inner wall, so that the shaft 3 drives the movable ring 9 to move up and down reciprocatingly.

[0030] The use steps of the utility model are as follows: when the device for cleaning the sludge on the water surface of the sedimentation tank is in use, the device is installed as a whole on the waterway above the sedimentation tank through the mounting frame 1, and the first pipeline 21 is connected with the high-pressure water pump or the high-pressure air pump as needed. When it is necessary to clean the sludge floating on the water surface of the sedimentation tank, the high-pressure water pump or the high-pressure air pump is started, and the high-pressure water or high-pressure air is transported to the nozzle 5 through the first pipeline 21 and the second pipeline 22 and sprayed out, so that the high-pressure water or high-pressure air can disperse the sludge floating on the water surface to ensure that the sludge can be normally settled. The motor 18 is controlled to reverse, and the motor 18 drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the shaft sleeve 2 to rotate through the engaged clamping block 13 and the clamping groove 15. The shaft sleeve 2 finally drives the nozzle 5 to rotate through the fixing frame 4, so that the sludge floating at various positions on the water surface of the sedimentation tank can be dispersed. When the inner wall of the sedimentation tank is to be flushed, the user can control the motor 18 to rotate forward. At this time, the motor 18 will only drive the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it will squeeze the slider 11 inside the movable ring 9 through the wavy structure of the slide groove 10, so that the rotating shaft 3 drives the movable ring 9 to move up and down reciprocatingly. During the process, the movable ring 9 drives the fixed frame 7 to move up and down through the lifting plate 6, and the fixed frame 7 then squeezes the slide bar 8. Since the nozzle 5 can rotate on the fixed frame 4, the fixed frame 7 will drive the nozzle 5 to swing up and down through the slide bar 8 when it moves up and down, thereby changing the direction of the nozzle 5, so that the user can control the direction of the nozzle 5. When the nozzle 5 is adjusted to face the inner wall of the sedimentation tank, the high-pressure water can be controlled to flush the inner wall of the sedimentation tank. In conjunction with the waterway, the inner wall of the canal around the sedimentation tank can also be flushed to disperse the floating foam generated by the water flow.
