Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank cleaning and sludge removal technology, specifically a sewage sedimentation tank cleaning and sludge removal device. Background Technology

[0002] Sedimentation tank cleaning and sludge removal refers to the removal of sludge deposited in a sedimentation tank through specific operations to ensure the normal operation and treatment effect of the sedimentation tank. This process usually utilizes gravity settling, water level pressure, or mechanical equipment to discharge the sludge accumulated at the bottom of the tank, thereby maintaining the cleanliness and efficient operation of the sedimentation tank, preventing sludge accumulation from affecting the treatment efficiency of the sedimentation tank, and avoiding problems such as sludge putrefaction and floating. The existing utility model patent with authorization announcement number CN218944425U discloses a sewage treatment sedimentation tank cleaning device. The sedimentation tank has a cleaning mechanism installed inside, a drive mechanism installed on the top of the sedimentation tank, and a discharge port on the outside of the sedimentation tank. A baffle matching the discharge port is installed on the sedimentation tank. Using the above technical solution, a vertical rod and a sliding plate, as well as a rotating rod and a sliding plate are used to clean the sedimentation tank. The coordination between the two components allows the movable plate to move to the right, and through the coordination between the connecting rod and the push plate, the push plate can then move to the right, thus facilitating the pushing of sludge from the bottom wall of the sedimentation tank to the right and out of the discharge port, thereby facilitating the thorough cleaning of the sludge inside the sedimentation tank. However, in actual use, the above technical solution requires opening the discharge port first, and using the guide plate and push plate to discharge sludge. However, in actual use, because sludge has a certain degree of adsorption, it is easily adsorbed onto the guide plate, and the flow rate of the discharge port is very limited, which can easily cause blockage during sludge discharge. At the same time, the above solution is not only cumbersome in operation, but the guide plate and push plate will also further reduce the space inside the sedimentation tank, greatly affecting the overall volume of sewage sedimentation.

[0003] Therefore, we propose a sewage sedimentation tank cleaning and sludge removal device to solve the above problems. Utility Model Content

[0004] To address the above technical problems, this utility model provides a sewage sedimentation tank cleaning and sludge removal device.

[0005] To solve the above-mentioned technical problems, the present invention provides a sewage sedimentation tank cleaning and sludge removal device, comprising a sedimentation tank body, the sedimentation tank body being topless and open at the front end, a push plate and a baffle plate being provided inside the sedimentation tank body, the top of the push plate and the top of the baffle plate being fixedly connected to two fixed frames, the bottom surface of each fixed frame being slidably engaged with the upper surface of the sedimentation tank body, a rack being fixedly connected inside each fixed frame, a fixed frame being fixedly connected to the outside of the sedimentation tank body, drive gears being meshed on the outer surface of the racks, two drive gears being fixedly connected to a rotating shaft, both ends of the rotating shaft being rotatably connected to the fixed frame, a servo motor being fixedly connected to the top of the fixed frame, the output end of the servo motor being drively connected to one end of the rotating shaft, two limiting plates being fixedly connected to the front end of the sedimentation tank body, a screen plate being fixedly connected to the bottom of the opposite side of the two limiting plates, the screen plate being fixedly connected to the bottom of the sedimentation tank body, a temporary storage tank being provided at the bottom of the screen plate, and an auger being installed at the bottom of the temporary storage tank.

[0006] Furthermore, a first bevel gear is fixedly connected to the output end of the servo motor, a second bevel gear is meshed with the first bevel gear, a worm is fixedly connected to the bottom of the second bevel gear, a worm wheel is meshed with the outer surface of the worm, the worm wheel is fixedly connected to one end of the rotating shaft, and both ends of the worm are rotatably connected to the fixed frame through support blocks.

[0007] Furthermore, grooves are provided on the top of both sides of the sedimentation tank body, and several rollers are rotatably connected to the bottom of the grooves. A protrusion is fixedly connected to the bottom of the fixing frame, and the protrusion is engaged in the groove. The bottom of the protrusion abuts against the top of the roller.

[0008] Furthermore, two reinforcing columns are fixedly connected to the opposite side of the push plate and the baffle.

[0009] Furthermore, reinforcing blocks are fixedly connected to both sides of the sedimentation tank body, and each reinforcing block is fixedly connected to a fixing frame.

[0010] This utility model has the following advantages compared with the prior art:

[0011] 1. This utility model, by setting a pusher plate, can move smoothly along the pool wall, forming a large-area and high-intensity pushing force on the sludge at the bottom of the pool. It can directly peel off the adsorbent sludge from the bottom of the pool, avoiding the accumulation of sludge in local structures. On the other hand, the pusher plate and the baffle are synchronously linked through two fixed frames. During the sludge discharge process, the baffle can quickly form a temporary guide channel and simultaneously open the other side of the sedimentation tank, moving the sludge towards the sludge discharge port. At the same time, the continuous pushing action of the pusher plate can provide stable power for sludge transportation, make up for the deficiency of limited flow of traditional sewage outlets, form a continuous and smooth sludge discharge flow, and completely solve the problem of sludge discharge blockage.

[0012] 2. This utility model, by setting a servo motor, connects a first bevel gear and a second bevel gear at the power output end of the servo motor, which can flexibly change the direction of power transmission. The worm gear fixed on the inner wall of the second bevel gear cooperates with the worm wheel, which can not only achieve speed reduction and torque increase, but also ensure the stability and accuracy of transmission. The rotating shaft fixed on the inner wall of the worm wheel drives the two drive gears to rotate synchronously. The drive gears mesh with the rack on the inner wall of the fixed frame, and finally drive the fixed frame to drive the push plate and baffle to slide along the inner wall of the sedimentation tank, automatically completing the sludge pushing and sludge discharge operation. The entire process only requires starting the servo motor to achieve fully automated operation, without the need for manual intervention in the step-by-step adjustment of the guide plate and push plate, simplifying the operation process. At the same time, by using the baffle and push plate as the two side plates of the sedimentation tank, the original effective volume of the sedimentation tank can be preserved to the maximum extent, ensuring that the sewage has sufficient residence time in the tank to complete the sedimentation and ensuring the sewage sedimentation effect.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 4The wastewater sedimentation tank cleaning and sludge removal device shown includes a sedimentation tank body 1, which is topless and open at the front end, with the upper edge of the front end protruding forward. A push plate 2 and a baffle 3 are installed inside the sedimentation tank body 1. Both the baffle 3 and the push plate 2 have integrated sealing gaskets to prevent leakage. Two fixing frames 12 are fixedly connected to the top of the push plate 2 and the top of the baffle 3. The bottom surface of each fixing frame 12 is slidably engaged with the upper edges of both sides of the sedimentation tank body 1 via slots and rollers 10. A rack 13 is fixedly connected inside each fixing frame 12. A fixing bracket 4 is fixedly connected to the outside of the sedimentation tank body 1. Drive gears 14 are meshed with the outer surfaces of the racks 13. Two drive gears 14 are fixedly connected to a rotating shaft 15. Both ends of the 5 are rotatably connected to the fixed frame 4. The top of the fixed frame 4 is fixedly connected to the servo motor 16. The output end of the servo motor 16 is connected to one end of the rotating shaft 15 for transmission. Two limiting plates 8 are fixedly connected to the front end of the sedimentation tank body 1. A screen plate 7 is fixedly connected to the bottom of the opposite side of the two limiting plates 8. The aperture of the screen plate 7 is not less than 5cm to avoid affecting the settling speed of the sludge and the sludge discharge effect. The screen plate 7 is fixedly connected to the bottom of the sedimentation tank body 1. The limiting plates 8 form a stable support for the screen plate 7 to ensure that it is not easily deformed under the pressure of the sludge. A temporary storage tank 5 is set at the bottom of the screen plate 7. An auger 6 is installed at the bottom of the temporary storage tank 5 at an angle. The auger 6 is driven by the auger motor to discharge the sludge. The servo motor 16 and the auger motor are connected to an external controller for convenient control.

[0020] The output end of the servo motor 16 is fixedly connected to a first bevel gear 17, which meshes with a second bevel gear 18. A worm gear 19 is fixedly connected to the bottom of the second bevel gear 18, and a worm wheel 20 meshes with the outer surface of the worm gear 19. The worm wheel 20 is fixedly connected to one end of the rotating shaft 15. Both ends of the worm gear 19 are rotatably connected to the fixed frame 4 through support blocks 21. The support blocks 21 provide support for the worm gear 19, ensuring the efficiency and stability of power transmission from the servo motor 16 through the bevel gear, worm gear 19, and worm wheel 20 to the rotating shaft 15, reducing energy loss. At the same time, a removable protective shell can be installed on the outside of the servo motor 16, the first bevel gear 17, the second bevel gear 18, the worm gear 19, and the worm wheel 20 to prevent foreign objects from entering the gears and affecting the transmission. The removable connection method facilitates subsequent maintenance.

[0021] The sedimentation tank body 1 has grooves on both sides of the top. Several rollers 10 are rotatably connected to the bottom of the grooves. The bottom of the fixed frame 12 is fixedly connected to a protrusion. The protrusion is engaged in the groove and the bottom of the protrusion is in contact with the top of the roller 10.

[0022] Two reinforcing columns 11 are fixedly connected to the opposite side of the push plate 2 and the baffle 3. During the sludge discharge process, the push plate 2 needs to withstand the reaction force of the sludge. If the connection between the push plate 2 and the baffle 3 is weak, deformation or relative displacement may occur, leading to problems such as asynchronous sliding or sludge leakage. The two ends of the reinforcing columns 11 are fixed to the push plate 2 and the baffle 3 respectively, forming a transverse support structure, which can disperse the sludge impact force borne by the push plate 2.

[0023] Both sides of the sedimentation tank body 1 are fixedly connected with reinforcing blocks 9. Each reinforcing block 9 is fixedly connected to the fixing frame 4. The reinforcing blocks 9 are fixed to the sedimentation tank body 1 and the fixing frame 4 respectively, forming a triangular support structure, which can distribute the load borne by the fixing frame 4, reduce vibration transmission, and ensure that the fixing frame 4 always remains stable.

[0024] The working process of this embodiment is as follows:

[0025] When workers need to perform sludge removal, they only need to turn on the servo motor 16 and the auger motor. After the servo motor 16 starts, its power output drives the first bevel gear 17 to rotate. The first bevel gear 17 drives the second bevel gear 18, which meshes with it, to rotate. The second bevel gear 18 drives the worm gear 19, which is fixed to the inner wall, to rotate. The worm gear 19 drives the worm wheel 20, which meshes with it, to rotate. The worm wheel 20 drives the rotating shaft 15, which is fixed to the inner wall, to rotate. The rotating shaft 15 drives the two drive gears 14 to rotate synchronously. The drive gears 14 mesh with the rack 13 on the inner wall of the fixed frame 12, driving the fixed frame 12 to move. The push plate 2 and baffle 3 slide along the inner wall of the sedimentation tank body 1. Since the push plate 2 and baffle 3 are located on both sides of the sedimentation tank and are supporting side plates on both sides of the sedimentation tank, when the push plate 2 and baffle 3 move, the push plate 2 pushes the sludge on the bottom wall of the sedimentation tank body 1 towards the sludge discharge direction. The baffle 3 moves synchronously to form a temporary guide channel, and the baffle 3 will move out of the sedimentation tank to the outside, thereby opening one side of the sedimentation tank. Then the push plate 2 gradually pushes out the sludge, and the sludge flows into the temporary storage tank 5 through the screen plate 7 and is transported to the outside by the auger 6 for centralized collection and cleaning, completing the sludge discharge operation. Finally, the baffle 3 and push plate 2 are reset.
