Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 4This utility model provides a technical solution: a sludge removal device for water treatment in a water plant, including a sedimentation tank 1, a sedimentation trough 2 inside the sedimentation tank 1, a drain outlet 15 inside the sedimentation tank 1 and located on one side of the sedimentation trough 2, a scraper 3 slidably connected inside the sedimentation trough 2, a support frame 4 fixedly connected to the top of the scraper 3, and multiple filter holes 6 inside the scraper 3. Guide rods 5 are installed on corresponding sides of the sedimentation tank 1, and the two guide rods 5 pass through the corresponding sides of the support frame 4, so that while the scraper 3 is moving, it automatically scrapes off the sludge in the sedimentation trough 2, filters the sewage through the multiple filter holes 6, intercepts the sludge, and pushes the sludge to be discharged to the drain outlet 15. Guide wheels 7 are installed on the top of both ends of the sedimentation tank 1. A bracket 8 is installed, with a roller 9 rotatably connected to the inner side of the bracket 8. Traction belts 10 are wound around the outer side of the roller 9. One end of each traction belt 10 is fixedly connected to the corresponding sides of the support frame 4. A first motor 11 is installed on the outer side of the bracket 8. The output end of the first motor 11 is fixedly connected to the roller 9 via a coupling, driving the two rollers 9 to rotate, allowing them to wind or unwind the two traction belts 10, thus displacing the support frame 4 and the scraper 3. An electric push rod 12 is installed on the top of the support frame 4. A baffle 13 is fixedly connected to the output end of the electric push rod 12, located on one side of the scraper 3. Multiple drainage holes 14 are provided inside the baffle 13, aligned with multiple filter holes 6 to prevent obstruction of the filter holes 6 from allowing wastewater to enter. During filtration, the baffle 13 can be displaced under the action of the electric push rod 12, causing the multiple drain holes 14 to be misaligned with the multiple filter holes 6. The remaining part of the baffle 13 then blocks the filter holes 6, separating the sewage from the sludge. This helps to prevent a large amount of untreated sewage from flowing out when the sludge is discharged. Limiting holes 25 are provided inside the support frame 4 on both sides corresponding to the electric push rod 12. Limiting rods 26 are slidably connected inside the limiting holes 25. One end of the limiting rods 26 is fixedly connected to the baffle 13, which helps to increase the stability of the baffle 13 in raising and lowering. A rotating shaft 16 is rotatably connected inside the sewage outlet 15. A sealing plate 17 is installed on the outside of the rotating shaft 16. The sealing plate 17 fits against the sewage outlet 15, and a rubber sealing ring is provided on the outside of the sealing plate 17. 27. This design helps increase the sealing between the sedimentation tank 1 and the discharge outlet 15, preventing sewage leakage. A self-locking motor 18 is installed on one side of the sedimentation tank 1. The output end of the self-locking motor 18 is fixedly connected to the rotating shaft 16 via a coupling, driving the rotating shaft 16 to rotate and causing the sealing plate 17 to flip, facilitating the control of the opening and closing of the discharge outlet 15 and assisting in the discharge of sludge. A conveyor 19 is installed on the side of the sedimentation tank 1 located at the discharge outlet 15. A collection box 20 is placed on the side of the conveyor 19 away from the sedimentation tank 1. Two conveying rollers 21 are rotatably arranged inside the conveyor 19, and a conveyor belt 22 is sleeved on the outside of the two conveying rollers 21. Multiple equidistant limiting plates 23 are fixedly connected to the surface of the conveyor belt 22, facilitating the transport of the discharged sludge to the collection box 20 for sludge collection and sorting.A second motor 24 is installed on the outer wall of the conveyor 19. The output end of the second motor 24 is fixedly connected to one of the conveyor rollers 21 via a coupling, providing power for the rotation of the conveyor roller 21 and the operation of the conveyor belt 22. A power supply assembly 28 is installed on the top of the support frame 4, located on one side of the limit rod 26. Power supplies providing power to the electric push rod 12, the first motor 11, and the second motor 24 are respectively provided inside the power supply assembly 28 and on the outside of the sedimentation tank 1 and the conveyor 19. A controller 29 is installed on one side of the sedimentation tank 1, located on top of the self-locking motor 18.

[0020] In summary, this sludge removal device for water treatment in a water plant operates by starting two first motors 11, which drive two rollers 9 to rotate, winding one traction belt 10 and unwinding the other. This causes one traction belt 10 to pull the support frame 4 towards the discharge port 15, while the other traction belt 10 releases the support frame 4. This allows the scraper 3 at the bottom of the support frame 4 to scrape off the sludge settled in the sedimentation tank 2 within the sedimentation tank 1. Since the multiple filter holes 6 in the scraper 3 are aligned with the multiple drainage holes 14 in the baffle 13, the wastewater passes directly through the filter holes 6 and drainage holes 14 for filtration. When the scraper 3 approaches the drain outlet 15 to a short distance, the electric push rod 12 drives the baffle 13 to move, causing the multiple drain holes 14 to be misaligned with the multiple filter holes 6. The baffle 13 blocks the multiple filter holes 6, dividing the sedimentation tank 2 into two separate spaces, separating the filtered sewage from the scraped sludge. The self-locking motor 18 drives the rotating shaft 16 to rotate, causing the sealing plate 17 inside the drain outlet 15 to flip, opening the drain outlet 15. With the scraper 3 pushing the sludge, the sludge is discharged. The running conveyor belt 22 transports the discharged sludge to the collection box 20 through multiple limit plates 23.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The installation methods between equipment are also the same as conventional installation methods in the prior art. For example, the two ends of the shaft-shaped parts are connected by bearings, the connection position of the valve component is provided with anti-leakage rubber strips, the outside of the threaded rod or screw is provided with dust cover, and the equipment can be driven by either built-in battery or external power supply. The control method is automatic control by a controller.
