Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to a self-adjusting reagent dosing device for sludge dewatering processes. Background Technology

[0002] Sludge dewatering refers to the process of removing water from fluidized raw, concentrated, or digested sludge, transforming it into semi-solid or solid sludge blocks. A search revealed Chinese Patent Publication No. CN215667692U, which discloses an adjustable sludge dewatering agent dosing device, including a dosing cylinder. During the dosing process, an adjusting device is used for segmented dosing. After dosing at the bottom, the cylinder is raised and lowered by 20 centimeters for a second dosing, and this process is repeated three times, dividing the dosing operation into three stages. This segmented dosing method is better suited for viscous substances like sludge. However, the existing technology described above has the following drawbacks: the dosing cylinder is a closed structure, and prolonged storage of chemicals easily leads to adhesion to the inner wall, making self-cleaning impossible and extremely inconvenient. Furthermore, it cannot be adjusted, allowing only single-point dosing, resulting in uneven agent distribution and affecting the sludge treatment effect. Therefore, a self-adjusting agent dosing device for the sludge dewatering process is proposed to solve the aforementioned problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a self-adjusting reagent dosing device for sludge dewatering process, which has the following beneficial effects:

[0018] 1. This self-adjusting reagent dosing device for sludge dewatering uses a drive mechanism and a cleaning mechanism. The output shaft of the drive motor rotates the rotating shaft, and the cleaning mechanism starts working simultaneously. The rotating shaft drives the fixed ring to rotate, and the fixed ring drives the horizontal plate to rotate through the connecting plate. Since the stabilizing wheel is slidably connected to the bottom of the corrugated guide plate fixed at the bottom of the top cover, the stabilizing wheel moves along the trajectory of the corrugated guide plate during the rotation of the horizontal plate. When the stabilizing wheel moves at the undulation of the corrugated guide plate, it pushes the moving frame to move up and down. The moving frame slides within the limiting ring through the stabilizing rod to ensure the stability of the movement. The moving frame drives the brush body to move up and down through the vertical plate. The brush body fits against the inner wall of the storage cylinder, thereby cleaning the inner wall of the storage cylinder and preventing the reagent from adhering to the cylinder wall, causing waste and affecting subsequent use. The return spring plays a buffering and resetting role during the movement of the moving frame, ensuring that the brush body can continuously and effectively contact the cylinder wall for cleaning. The combination of rotation and up and down movement simulates manual brushing to improve cleaning efficiency and achieves the purpose of self-cleaning the inner wall of the storage cylinder.

[0019] 2. This self-adjusting reagent dosing device for sludge dewatering uses an adjustment mechanism and a dosing mechanism. The servo motor in the adjustment mechanism starts, driving the left threaded rod to rotate. The left threaded rod, through a transmission gear and transmission chain, drives the right threaded rod to rotate synchronously. The threaded blocks connected to the outer threads of the two threaded rods move laterally along the threaded rods, thereby driving the dosing mechanism connected to the threaded blocks to move back and forth, achieving horizontal adjustment of the dosing position. After the reagent enters the diversion pipe, it is sprayed out through nozzles evenly distributed at the bottom. During the movement of the dosing mechanism driven by the adjustment mechanism, the moving plate in the dosing mechanism slides within the slotted hole via a support rod. Simultaneously, a telescopic spring provides buffering and reset capabilities, ensuring the stability of the dosing process. The right side of the moving plate is slidably connected to a limiting guide plate via a U-shaped frame and a round rod, further restricting the moving plate's trajectory. This allows the nozzles to move back and forth while expanding their lateral movement range, enabling the nozzles to evenly add the reagent to the designated position in the treatment tank, achieving adjustable reagent dosing.

[0040] During use, check that all components of the equipment are securely installed and that all connections are properly sealed.

The agent is sprayed into the treatment tank 2 through the diversion pipe 806 and the nozzle 807. During the dosing process, the position of the dosing mechanism 8 can be finely adjusted again according to actual needs to ensure uniform dosing of the agent.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] In summary, this self-adjusting reagent dosing device for sludge dewatering utilizes a drive mechanism 4 and a cleaning mechanism 5. The output shaft of the drive motor 42 drives the rotating shaft 43 to rotate. Simultaneously, the cleaning mechanism 5 operates, causing the rotating shaft 43 to rotate the fixed ring 502. The fixed ring 502, through the connecting plate 503, drives the horizontal plate 505 to rotate. Since the stabilizing wheel 507 is slidably connected to the bottom of the corrugated guide plate 512 fixed to the bottom of the top cover 32, the stabilizing wheel 507 moves along the trajectory of the corrugated guide plate 512 during the rotation of the horizontal plate 505. When the stabilizing wheel 507 moves along the undulating sections of the corrugated guide plate 512, it pushes the moving frame 506 up and down. The moving frame 506 slides within the limiting ring 501 via the stabilizing rod 504, ensuring stable movement. The moving frame 506 drives the brush body 511 to move up and down via the upright plate 510. The brush body 511 adheres to the inner wall of the storage cylinder 1, thus cleaning the inner wall and preventing the medicine from adhering to the cylinder wall, causing waste and affecting subsequent use. The return spring 509 acts as a buffer and reset mechanism during the movement of the moving frame 506, ensuring that the brush body 511 can continuously and effectively contact the cylinder wall for cleaning. The combination of rotation and up-and-down movement simulates manual brushing, improving cleaning efficiency and achieving the self-cleaning purpose of the inner wall of the medicine storage cylinder. Through the setting of the adjustment mechanism 7 and the dosing mechanism 8, the adjustment mechanism 7... The servo motor 71 starts, driving the left threaded rod 74 to rotate. The left threaded rod 74 drives the right threaded rod 74 to rotate synchronously through the transmission gear 76 and the transmission chain 77. The threaded block 75 connected to the outer threads of the two threaded rods 74 moves laterally along the threaded rods 74, thereby driving the dosing mechanism 8 connected to the threaded block 75 to move back and forth, realizing the adjustment of the dosing position in the horizontal direction. After the agent enters the diversion pipe 806, it is sprayed out through the nozzles 807 that are evenly distributed at the bottom. During the process of the adjustment mechanism 7 driving the dosing mechanism 8 to move, the moving plate 804 in the dosing mechanism 8 slides in the strip hole 802 through the support rod 803, and at the same time, the telescopic spring 805... Providing a certain buffering and reset capability to ensure the stability of the dosing process, the right side of the moving plate 804 is slidably connected to the limiting guide plate 809 through the U-shaped frame 810 and the round rod 811, further restricting the movement trajectory of the moving plate 804. This allows the nozzle 807 to move forward and backward while expanding its left and right movement range, enabling the nozzle 807 to evenly add the agent to the designated position in the treatment tank 2. This achieves the purpose of adjustable agent dosing and solves the problem that the chemical storage tank is a closed structure, and long-term storage of chemical agents easily adheres to the inner wall, making self-cleaning impossible, extremely inconvenient to clean, and unable to be adjusted, resulting in uneven agent dosing and affecting the sludge treatment effect.
