[0002] The raw water from the centrally driven sludge scraper is distributed through the central water distribution cylinder and flows radially to the overflow trough around the pool. As the flow rate decreases, suspended solids in the water are separated and settle to the bottom of the pool, and the supernatant is discharged out of the pool through the overflow weir plate.

[0003] The authorized publication number "CN219848306U" describes a "center-driven sludge scraper as follows: a crossbeam; a main shaft rotatably connected to the bottom of the crossbeam; two support plates, each movably connected to the bottom of the circumferential surface of the main shaft; two scraper blades, each fixed to the bottom of the two support plates; four hooks, each fixed to the upper part of the circumferential surface of the main shaft; and two chains, one end of which is fixed to the top of the two support plates, and the other end of which is fitted onto the circumferential surface of two of the hooks."

[0004] The aforementioned patent can be used to scrape sludge from sedimentation tanks on different surfaces, making it more practical. However, it is not easy to adjust the scraping radius according to the diameter of the sedimentation tank. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1

[0037] Please see Figures 1-5 The technical solution provided in this embodiment is as follows:

[0038] A center-driven sludge scraper consists of a crossbeam 1, a support mechanism, a drive mechanism, an adjustment mechanism, a screw D18, and a sludge scraping mechanism. Two support wheels 16 are provided, and the two support wheels 16 are symmetrically arranged on the adjustment mechanism.

[0039] In a specific embodiment of this utility model, each support wheel 16 is installed on each auxiliary rod 15. The support wheel 16 can support the main rod 10, thereby reducing the pressure on the main rod 10. The support wheel 16 can also control the distance between the mounting plate 11 and the bottom of the sedimentation tank, thereby ensuring that the rubber scraper 14 fits in close contact with the bottom of the sedimentation tank, thus improving the sludge scraping effect.

[0040] Specifically, there are two sets of support mechanisms, which are symmetrically arranged on the crossbeam 1. Each set of support mechanisms includes a telescopic beam 3, a connecting steel 4, and screws A5. There are two telescopic beams 3, which are movably inserted into the crossbeam 1. Each telescopic beam 3 is detachably connected to the crossbeam 1 by two screws A5. The connecting steel 4 is fixedly connected to the two telescopic beams 3.

[0041] In a specific embodiment of this utility model, the connecting steel 4 is used to connect two telescopic beams 3. The telescopic beams 3 are movably inserted into the crossbeam 1, so that the telescopic beams 3 can move on the crossbeam 1, thereby adjusting the distance between the connecting steel 4 and the crossbeam 1. This allows for adjustment according to different sizes of sedimentation tanks, thus enabling installation on sedimentation tanks of different sizes.

[0042] Specifically, the drive mechanism is located on the crossbeam 1. The drive mechanism includes a drive motor 2 and a mounting shaft 6. The drive motor 2 is fixedly connected to the top of the crossbeam 1, and the output end of the drive motor 2 rotates through the crossbeam 1 and extends to the outside of the crossbeam 1. The mounting shaft 6 is fixedly connected to the output end of the drive motor 2.

[0043] In a specific embodiment of this utility model, the output end of the drive motor 2 rotates to drive the mounting shaft 6 to rotate, and the rotation of the mounting shaft 6 drives the two main rods 10 to perform circular motion.

[0044] Specifically, there are two sets of length adjustment components, which are symmetrically arranged on the mounting shaft 6. Each set of length adjustment components includes a main rod 10, a secondary rod 15, a connecting flange 17, and a screw D18. The main rod 10 is movably hinged to the surface of the mounting shaft 6, the secondary rod 15 is movably inserted into the main rod 10, and the connecting flange 17 is fixedly connected to the surface of the secondary rod 15. The connecting flange 17 and the main rod 10 are detachably connected through multiple connecting flanges 17.

[0045] In a specific embodiment of this utility model, the maximum diameter of the main rod 10 is the same as the maximum diameter of the secondary rod 15. The main rod 10 and the secondary rod 15 can be connected by a connecting flange 17 and screws D18, so that the number of rubber scrapers 14 can be adjusted by connecting the main rod 10 and the secondary rod 15, and the number of rubber scrapers 14 can be adjusted according to the diameter of the sedimentation tank.

[0046] Specifically, the angle adjustment component is located on the mounting shaft 6. The angle adjustment component is connected to two sets of length adjustment components. The angle adjustment component includes a hinged sleeve 7, a screw B8, and a connecting rod 9. The hinged sleeve 7 is slidably mounted on the mounting shaft 6, and the hinged sleeve 7 is detachably connected to the mounting shaft 6 by multiple screws B8. There are two connecting rods 9. Both connecting rods 9 are movably hinged to the hinged sleeve 7, and each connecting rod 9 is movably hinged to each main rod 10.

[0047] In a specific embodiment of this utility model, the main rod 10 rotates, causing the connecting rod 9 to move. The movement of the connecting rod 9 causes the hinged sleeve 7 to slide on the mounting shaft 6. While fixing the hinged sleeve 7, the tilt angle of the main rod 10 can also be fixed. The main rod 10 and the mounting shaft 6 are movably hinged, allowing the main rod 10 to rotate, thereby adjusting the angle between the main rod 10 and the mounting shaft 6. This allows the tilt angle of the main rod 10 to be adjusted according to the slope of the bottom of the sedimentation tank.

[0048] Specifically, the sludge scraping mechanism is provided in multiple sets, all of which are located on the adjustment mechanism and are arranged in sequence. Each set of sludge scraping mechanism includes a mounting plate 11, a mounting sleeve 12, a screw C13, and a rubber scraper 14. The mounting sleeve 12 is slidably mounted on the main rod 10 and is detachably connected to the main rod 10 by the screw C13. The mounting plate 11 is fixedly connected to one end of the mounting sleeve 12, and the rubber scraper 14 is fixedly connected to one side of the mounting plate 11.

[0049] In a specific embodiment of this utility model, the mounting sleeve 12 can be slidably mounted on the main rod 10 and the auxiliary rod 15 respectively. The mounting sleeve 12 is slidably mounted on the main rod 10, so that the mounting sleeve 12 can slide on the main rod 10, thereby adjusting the distance between the two rubber scrapers 14. At the same time, the mounting sleeve 12 can be detached from the main rod 10, so that the rubber scrapers 14 are easy to disassemble and replace.

[0050] The working principle or process of the center-driven sludge scraper provided by this utility model is as follows: Pulling the connecting steel 4 moves the connecting steel 4, which in turn moves the two telescopic beams 3. After the two telescopic beams 3 move, screws A5 are threaded onto the crossbeam 1 and the telescopic beams 3. The auxiliary rod 15 is movably inserted into the main rod 10, and the connecting flange 17 is detachably connected to the main rod 10 via screw D18. Multiple mounting sleeves 12 are slidably fitted onto the main rod 10 and the auxiliary rod 15, and screws C13 are threaded onto the mounting sleeves 12, thereby fixing the mounting sleeves 12 in place. 2. After the support wheel 16 is in contact with the bottom of the sedimentation tank, it will adjust the tilt angle of the main rod 10, causing the main rod 10 to rotate. After the main rod 10 rotates, it drives the connecting rod 9 to move. The movement of the connecting rod 9 causes the hinge sleeve 7 to slide on the mounting shaft 6. The screw B8 is threaded onto the hinge sleeve 7, thereby fixing the hinge sleeve 7 to the mounting shaft 6. The output end of the drive motor 2 drives the mounting shaft 6 to rotate. The rotation of the mounting shaft 6 drives the two main rods 10 to make circular motion. The circular motion of the main rods 10 drives the rubber scraper 14 to make circular motion.

[0051] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
