Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank sludge treatment, and in particular to a high-efficiency automatic sludge cleaning device for sedimentation tanks. Background Technology

[0002] Wastewater sedimentation tanks are devices that use gravity to allow suspended particles with a density greater than water to settle naturally, achieving solid-liquid separation. Their core principle is to control the water flow rate and residence time, ensuring that the particle settling velocity is greater than the water flow velocity, thereby separating sludge from clean water. Sedimentation tanks are one of the most economical and energy-efficient units in wastewater treatment, requiring no additional energy. Physical sedimentation significantly reduces suspended solids and organic load, laying the foundation for subsequent biological or chemical treatment. The sludge that accumulates at the bottom of the sludge tank after sedimentation usually needs to be treated, requiring a sedimentation tank sludge cleaning device to remove the sludge.

[0003] For example, patent number (CN221846211U) discloses a sludge cleaning device for sewage sedimentation tanks, relating to the field of sludge cleaning technology for sewage sedimentation tanks. This sludge cleaning device includes a sewage sedimentation tank body, a motor mounted on one side of the body, a transmission mechanism inside the body, and a cleaning mechanism inside the body. This sludge cleaning device, by using a sliding strip, allows for the cleaning of sludge at the bottom of the sewage sedimentation tank body. First, a rotating shaft drives a traction rope. When the shaft rotates clockwise, the traction rope drives the sliding strip and scraper to slide from the side away from the sludge tank to the side of the sludge tank at the bottom of the sedimentation tank body, facilitating the cleaning of the sludge at the bottom of the sedimentation tank body and collecting the sludge inside the sludge tank. This device facilitates the cleaning of sludge at the bottom of the sewage sedimentation tank body.

[0004] Currently, the automatic sludge cleaning device for high-efficiency sedimentation tanks has certain limitations in its cleaning structure. The sludge being cleaned is quite viscous, and the cleaning trough structure has limited dimensions. As a result, the cleaning trough structure is prone to blockage during the sludge cleaning process, which affects the normal progress of the sludge cleaning work.

[0005] Therefore, to address the above problems, a high-efficiency automatic sludge cleaning device for sedimentation tanks with an anti-clogging structure can be designed. Utility Model Content

[0006] In order to overcome the problem that the cleaning trough structure of the high-efficiency sedimentation tank sludge automatic cleaning device is easily blocked during operation, which affects the normal progress of sludge cleaning work.

[0007] The technical solution of this utility model is as follows: an efficient automatic sludge cleaning device for sedimentation tanks, including a sedimentation tank body and a screening box body. A sedimentation tank is fixedly installed at the lower end of the sedimentation tank body. A cleaning pipe is fixedly installed at the lower end inside the sedimentation tank. A drive module is fixedly installed at the right end of the cleaning pipe. The output end of the drive module extends into the cleaning pipe and is fixedly installed with a drive shaft. Transmission blades are fixedly installed on the surface of the drive shaft. A sealing cover is connected to the left end of the cleaning pipe. A support frame is fixedly installed inside the sealing cover at the left end of the cleaning pipe. A collection frame is provided at the upper end of the screening box body. A drain screen is fixedly installed on the inner surface of the collection frame. A stabilizing extrusion component is provided on the upper side inside the screening box body. A drain pipe is fixedly connected to the lower side of the front end of the screening box body. Moving rollers are provided on the side of the lower end of the screening box body.

[0008] Preferably, the sedimentation tank equipment is equipped with such a functional pipe port for connecting to other equipment and for sewage supply and discharge, facilitating normal sewage sedimentation treatment. The sealing cover can control the opening and closing of the cleaning pipe channel. The screening box is easy to move and transfer. The drive module can drive the transmission shaft to rotate. The transmission blades can push the sludge to the outside of the equipment during rotation. The sedimentation tank facilitates the concentrated sedimentation of sludge and makes it easier for it to slide down. The screening box can receive the discharged sludge, and the drain screen plate inside the collection frame can drain the sludge.

[0009] Preferably, the sedimentation tanks are evenly spaced and have a trapezoidal structure design, with the tanks interconnected by cleaning pipes.

[0010] Preferably, a mounting frame is fixedly installed on the side of the lower end of the sedimentation tank, a support leg is fixedly installed on the lower end of the sedimentation tank, a connecting plate is fixedly installed on the mounting frame, and the connecting plate is fixedly connected to the drive module.

[0011] Preferably, the output end of the drive module is rotatably connected to the cleaning trough. The drive module is used to drive the transmission shaft to rotate. The transmission blades are designed with a spiral structure and are adapted to the inner surface of the cleaning trough.

[0012] Preferably, the left end of the cleaning pipe groove is detachably connected to the sealing cover plate, the support frame has a U-shaped structure design, and the left end of the drive shaft extends to the outside of the cleaning pipe groove and is rotatably connected to the support frame.

[0013] Preferably, the collection frame is snapped into the screening box, a sealing cap is detachably connected to the drain pipe, handles are fixedly installed on both the front and rear sides of the upper end of the collection frame, and a push-pull rod is fixedly installed on the left end of the screening box.

[0014] Preferably, the stabilizing extrusion assembly includes a movable groove, inside which an extrusion spring is fixedly installed, and on the extrusion spring is a locking ball, the surface of which is slidably connected to the movable groove.

[0015] The beneficial effects of this utility model are:

[0016] 1. This high-efficiency sedimentation tank sludge automatic cleaning device allows sludge to settle in a concentrated manner through a sedimentation tank, making it easier for the sludge to slide down and into the cleaning pipe. Rotating conveyor blades push the sludge out of the sedimentation tank equipment, ensuring the working efficiency of the cleaning device and greatly reducing the workload of the staff. This structure can also effectively prevent sludge from clogging the cleaning pipe, facilitating the normal operation of sludge cleaning and enhancing the ease of use of the high-efficiency sedimentation tank sludge automatic cleaning device.

[0017] 2. This high-efficiency sedimentation tank sludge automatic cleaning device, through the screening box and auxiliary sludge cleaning work, facilitates the centralized collection and transfer of the cleaned sludge. At the same time, the collection frame facilitates the drainage of wastewater from the sludge, separating the sludge and wastewater. The compression spring can cause the surface of the locking ball to protrude slightly out of the movable groove, forming a compression on the upper extension of the collection frame, which facilitates the stability of the locking between the collection frame and the screening box. This mechanism also facilitates the disassembly of the collection frame, making the sludge collection work and subsequent sludge-wastewater separation and treatment work more convenient.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5 This utility model provides an embodiment of an efficient automatic sludge cleaning device for sedimentation tanks, comprising a sedimentation tank body 1 and a screening box body 2. A sedimentation tank 3 is fixedly installed at the lower end of the sedimentation tank body 1. A cleaning pipe 4 is fixedly installed at the lower end inside the sedimentation tank 3. A drive module 5 is fixedly installed at the right end of the cleaning pipe 4. A drive shaft 6 is fixedly installed inside the cleaning pipe 4 at the output end of the drive module 5. A transmission blade 7 is fixedly installed on the surface of the drive shaft 6. A sealing cover plate 8 is provided and connected to the left end of the cleaning pipe 4. A support frame 9 is fixedly installed inside the sealing cover plate 8 at the left end of the cleaning pipe 4. The upper end of the screening box body 2... A collection frame 10 is provided, and a drain mesh plate 11 is fixedly installed on the inner surface of the collection frame 10. A stable extrusion component is provided on the upper side inside the screening box 2. A drain pipe 12 is fixedly connected to the lower side of the front end of the screening box 2. A moving roller 13 is provided on the lower side of the screening box 2. The drive module 5 drives the transmission blade 7 to rotate and pushes the sludge to the outside of the equipment. The sedimentation tank 3 facilitates the concentrated sedimentation of sludge and makes it easier for the sludge to slide down to the cleaning pipe trough 4, realizing the automatic sludge cleaning work. This structure can effectively avoid the situation of sludge clogging the cleaning trough structure, and facilitate the normal operation of sludge cleaning work.

[0026] Please see Figures 1-3In this embodiment, the sedimentation tanks 3 are evenly spaced and have a trapezoidal structure. The sedimentation tanks 3 are interconnected through cleaning pipes 4. A mounting frame 14 is fixedly installed on the lower side of the sedimentation tank 1. Support legs are fixedly installed on the lower end of the sedimentation tank 3. A connecting plate 15 is fixedly installed on the mounting frame 14. The connecting plate 15 is fixedly connected to the drive module 5. The output end of the drive module 5 is rotatably connected to the cleaning pipe 4. The drive module 5 is used to drive the transmission shaft 6 to rotate. The transmission blades 7 have a spiral structure design and are adapted to the inner surface of the cleaning pipe 4. The left end of the cleaning pipe 4 is detachably connected to the sealing cover plate 8. The support frame 9 has a U-shaped structure design, and the left end of the transmission shaft 6 extends... The outer side of the cleaning pipe trough 4 is rotatably connected to the support frame 9. The drive module 5 can drive the transmission shaft 6 to rotate (the drive module 5 can be set as a drive motor or similar drive component, and the drive module 5 needs to control the rotation direction of the transmission blades 7 to ensure that the sludge can be pushed outward). The transmission blades 7 can push the sludge to the outside of the equipment during rotation. The support frame 9 facilitates the rotation of the transmission shaft 6, improves its operational stability, and avoids affecting the discharge of sludge. The sedimentation tank 3 can concentrate and settle the sludge, and make it easier for it to slide down, so that the sludge slides down to the cleaning pipe trough 4 (this process can also be combined with water pipe flushing to improve the transmission efficiency of the transmission blades 7 and make the cleaning work more thorough).

[0027] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In this embodiment, the collection frame 10 is snapped into the screening box 2. A sealing cap 16 is detachably connected to the drain pipe 12. Handles are fixedly installed on both the front and rear sides of the upper end of the collection frame 10. A push-pull rod is fixedly installed on the left end of the screening box 2. The stabilizing extrusion assembly includes a movable groove 17. An extrusion spring 18 is fixedly installed inside the movable groove 17. A locking ball 19 is fixedly installed on the extrusion spring 18. The surface of the locking ball 19 is slidably connected to the movable groove 17. The sludge discharged through the screening box 2 is received, and the sludge is drained by the drain screen plate 11 inside the collection frame 10. The sludge contains a certain amount of moisture, and the mesh size of the drain screen 11 is appropriate, which can both basically hold and retain the sludge and allow the sewage to flow out smoothly. This allows the sewage to flow into the bottom of the screening box 2, while the sludge remains inside the collection frame 10, which facilitates the subsequent separation and treatment of sludge and sewage. The compression spring 18 can drive the surface of the locking ball 19 to slightly protrude from the movable groove 17, forming a compression on the upper extension of the collection frame 10, which helps to improve the stability of the locking between the collection frame 10 and the screening box 2. This mechanism also facilitates the disassembly of the collection frame 10. The drain pipe 12, together with the sealing cap 16, facilitates the control of drainage.

[0028] During operation, the wastewater is drained and the sealing cover 8 is opened. At the same time, the screening box 2 is pushed to the sewage outlet of the cleaning pipe trough 4. The drive module 5 drives the transmission shaft 6 to rotate, so that the transmission blades 7 push the sludge to the outside of the equipment during the rotation. The sedimentation tank 3 has a trapezoidal structure design, which facilitates the concentrated sedimentation of sludge and makes it easier for the sludge to slide down. The sludge slides down to the cleaning pipe trough 4, which further realizes the automatic cleaning of sludge in the high-efficiency sedimentation tank. The sludge discharged by the screening box 2 is received by the screening box 2, and the sludge is drained by the drain screen plate 11 inside the collection frame 10. The wastewater flows into the bottom of the screening box 2, while the sludge remains inside the collection frame 10, which facilitates the subsequent separation and treatment of sludge and wastewater.

[0029] Through the above steps, the drive module 5 drives the transmission blades 7 to rotate and pushes the sludge to the outside of the equipment. The sedimentation tank 3 facilitates the concentrated sedimentation of the sludge and makes it easier for the sludge to slide down to the cleaning pipe 4, thus realizing the automatic sludge cleaning work. This structure can effectively avoid the situation where the sludge blocks the cleaning trough structure, which facilitates the normal operation of the sludge cleaning work. This solves the problem that the cleaning trough structure is easily blocked when the high-efficiency sedimentation tank sludge automatic cleaning device is working, which affects the normal operation of the sludge cleaning work.
