[0002] In the water treatment process, sedimentation tanks play a vital role. Among them, the honeycomb filter layer, as a high-efficiency filter medium, plays a decisive role in removing suspended solids in water and improving water quality. However, over time, these filter layers are susceptible to accumulation and blockage by impurities such as silt and organic matter carried in the water, resulting in reduced filtration efficiency, affecting the effluent quality, and may even cause anaerobic conditions and promote sludge floating.

DETAILED DESCRIPTION

[0022] like Figure 1~2 As shown, a filter layer cleaning device for a sedimentation tank comprises a honeycomb filter layer 12 installed in a sedimentation tank 1, wherein a movable sliding plate 2 is provided on the sedimentation tank 1, a transverse plate 4 that moves horizontally to the left and right is provided on the sliding plate 2, a lifting and sliding fixed frame 8 is provided below the transverse plate 4, and a plurality of nozzles 9 are provided on the fixed frame 8, and the nozzles 9 are aimed at the through holes on the honeycomb filter layer 12. The sliding plate 2 moves to cover the entire sedimentation tank 1, the transverse plate 4 that moves horizontally to the left and right can drive the plurality of nozzles 9 on the fixed frame 8 to alternately align with the through holes on the honeycomb filter layer 12, and the lifting and sliding fixed frame 8 can drive the nozzles 9 to descend above the through holes of the honeycomb filter layer 12 or enter the through holes for high-pressure water spray cleaning.

[0023] The honeycomb filter layer 12 installed inside the sedimentation tank 1 is a key part of the filtration process, and in order to effectively clean the blockages on these filter layers, a moving mechanism above is designed. The sliding plate 2 can move along the length of the tank at the top of the sedimentation tank 1 to ensure that the entire filter layer can be covered and cleaned.

[0024] The traverse plates 4 on the sliding plate 2 increase the flexibility of cleaning. They can move left and right, which means that no matter how the through holes on the filter layer are located, the nozzles 9 can accurately align and enter these through holes through the traverse action. This design ensures that there is no dead angle in cleaning and improves the cleaning efficiency and effect.

[0025] The lifting and sliding function of the fixed frame 8 allows the nozzle 9 to not only clean the surface of the filter layer, but also to penetrate into the through hole for more thorough flushing. This ability to dynamically adjust the height is particularly important for removing deep sediments and helps to restore the water permeability of the filter layer.

[0026] The nozzle 9 sprays water at high pressure to flush away impurities and blockages attached to the filter layer using the power of water. High-pressure water jet technology is widely used in industrial cleaning because it can effectively remove stubborn stains without damaging the substrate and is suitable for filter media of various materials.

[0027] Further preferably, based on the above mechanical structure, the device has a high potential for automation transformation. By adding sensors, PLC controllers and precise control of drive motors, the cleaning process can be fully automated, reducing manual intervention and improving operation safety and efficiency.

[0028] Preferably, both sides of the sliding plate 2 are moved against the sedimentation tank 1 through the first sliding assembly 3, and rotating screws 11 are provided on both sides of the sedimentation tank 1. The screws 11 are connected to the sliding plate 2 through the threaded sleeves 202, and the threaded sleeves 202 are threadedly connected to the screws 11, and the threaded sleeves 202 are fixed to the bottom of the sliding plate 2. The first sliding assembly 3 is a slider and a slide rail, the slide rail is fixed on the sedimentation tank 1, and the slider is fixed to the bottom of the sliding plate 2. The rotation of the screw 11 can drive the threaded sleeves 202 and the sliding plate 2 to move, so that the sliding plate 2 slides to cover the entire sedimentation tank 1.

[0029] The first sliding assembly 3 forms a stable linear guide system through the combination of the slider and the slide rail. The slide rail is fixed on both sides of the sedimentation tank, providing a smooth and straight moving track for the slider, ensuring that the sliding plate remains stable and does not deviate from the track during movement.

[0030] The screw rod 11 is linked with the wire sleeve 202. When the screw rod 11 is rotated electrically or manually, its spiral pattern interacts with the corresponding thread inside the wire sleeve 202 to generate linear motion. The wire sleeve 202 is fixed to the bottom of the sliding plate, so when the screw rod 11 rotates, it will directly drive the sliding plate 2 to move horizontally along the slide rail.

[0031] Through the precise control of the screw rod 11, the sliding plate 2 can slide smoothly along the length direction of the sedimentation tank 1, and because the screw rod 11 and the sliding plate 2 are connected by threads, reliable driving force and position control are provided to ensure that the sliding plate 2 can accurately cover every part of the sedimentation tank. This design not only improves the flexibility of the cleaning operation, but also facilitates the adjustment of the cleaning area according to actual needs, realizing a full range of automated or semi-automated cleaning operations.

[0032] Preferably, both ends of the screw rod 11 are against the sedimentation tank 1 through bearing seats, a main shaft 13 is provided between the screw rods 11 on both sides of the sedimentation tank 1, the main shaft 13 is meshed with the screw rod 11 through multiple bevel gears for transmission, a motor 14 is provided at the end of the main shaft 13, and the middle of the main shaft 13 is against the sedimentation tank 1 through multiple bearing seats. The motor 14 drives the main shaft 13 to rotate, and drives the screw rods 11 on both sides to rotate synchronously through the meshing rotation of the bevel gears, so as to drive the sliding plate 2 to move and cover the entire sedimentation tank 1.

[0033] Both ends of the screw rod 11 are firmly mounted on both sides of the sedimentation tank 1 through bearing seats. This design not only ensures the stable operation of the screw rod, but also effectively disperses the load during the transmission process, avoiding wear or failure caused by vibration or uneven force.

[0034] The main shaft 13 is connected to the screw rods 11 on both sides through multiple bevel gears. This ensures that the screw rods 11 on both sides can rotate synchronously at the same speed and direction, which is crucial to ensure the uniform linear movement of the sliding plate 2. The tooth shape design of the bevel gear can withstand high torque transmission and is suitable for such transmission applications that require precise synchronization.

[0035] The motor 14 is directly mounted on one end of the main shaft 13 and serves as the power source of the entire system. The start-up and speed regulation of the motor 14 can accurately control the rotation speed of the main shaft, thereby regulating the moving speed of the sliding plate 2 to meet the speed regulation requirements under different cleaning needs. Driven by the motor 14, automatic control can be easily achieved to improve the efficiency and consistency of the cleaning operation.

[0036] In order to further enhance the stability of the main shaft 13, the middle part is also fixed on the sedimentation tank 1 through multiple bearing seats. This not only balances the force on the main shaft and prevents bending deformation, but also reduces vibration during operation and ensures the long-term stable operation of the transmission system.

[0037] Preferably, the two sides of the bottom of the transverse plate 4 are connected to the sliding plate 2 through the second sliding assembly 5, and a transverse pushing mechanism 10 is provided on one side of the transverse plate 4. The piston rod end of the transverse pushing mechanism 10 is fixed on the transverse plate 4, and the cylinder is fixed on the sliding plate 2. The second sliding assembly 5 is a slide rail and a slider, the slider is fixed on the bottom of the transverse plate 4, and the slide rail is fixed on the sliding plate 2; the transverse pushing mechanism 10 is a cylinder, or a hydraulic cylinder, or an electric push rod, and the transverse plate 4 can be driven to move horizontally left and right through the transverse pushing mechanism 10, so that the nozzle 9 on the fixed frame 8 is aligned with the through hole on the honeycomb filter layer 12.

[0038] The transverse plate 4 is also moved transversely by a second sliding assembly 5 composed of a slide rail and a slider. The slide rail is fixed on the sliding plate 2, and the slider is fixed to the bottom of the transverse plate 4. Such a design ensures that the transverse plate 4 slides smoothly and accurately on the sliding plate 2.

[0039] The lateral push mechanism 10, as the power source for the lateral movement of the lateral plate 4, can be a cylinder, a hydraulic cylinder or an electric push rod. These three types of drive devices have their own advantages and can be selected according to the specific application environment and needs. Cylinders and hydraulic cylinders can usually provide greater thrust and are suitable for occasions that require greater driving force, while electric push rods are known for their precise control and low noise characteristics. Regardless of which form is adopted, the lateral push mechanism 10 pushes the lateral plate 4 to move left and right through the direct connection between its piston rod and the lateral plate 4.

[0040] Through the precise control of the transverse push mechanism 10, the transverse plate 4 and the fixed frame 8 and the nozzle 9 fixed thereunder can be moved laterally as needed to ensure that the nozzle can be accurately aligned with each through hole on the honeycomb filter layer 12. This precise alignment capability is crucial for efficient cleaning, ensuring that each through hole is fully cleaned and the filter layer is restored to its optimal working state.

[0041] Preferably, a pushing mechanism 7 and a guide column 6 are provided between the transverse plate 4 and the fixed frame 8, the guide column 6 is provided on both sides of the pushing mechanism 7, a through groove 201 is provided in the middle of the sliding plate 2, and the pushing mechanism 7 and the guide column 6 are provided in the through groove 201;

[0042] One end of the guide column 6 is fixed to the fixing frame 8, and the other end is connected to the transverse plate 4 through a sliding sleeve;

[0043] The piston rod end of the push mechanism 7 is fixed on the fixed frame 8, and the cylinder is fixed on the transverse plate 4. The push mechanism 7 is a cylinder, a hydraulic cylinder, or an electric push rod, and the push mechanism 7 can drive the fixed frame 8 to move up and down, so that the multiple nozzles 9 at the bottom of the fixed frame 8 move downward to the top of the honeycomb filter layer 12 or enter the through hole, shortening the flushing distance of the nozzle 9 and ensuring clean cleaning; the guide column 6 can ensure that the fixed frame 8 moves up and down smoothly and reliably.

[0044] One end of the guide column 6 is fixed on the fixed frame 8, and the other end is connected to the transverse plate 4 through a sliding sleeve. This design not only ensures the stable guiding effect of the guide column 6 during the lifting and lowering process of the fixed frame, but also realizes flexible sliding through the sliding sleeve structure, avoiding the resistance or instability that may be caused by direct rigid connection, and improving the smoothness of the overall system.

[0045] The piston rod end of the push mechanism 7 is fixed on the fixing frame 8, and the cylinder part is fixed on the transverse plate 4. When the push mechanism 7 is working, the expansion and contraction of the piston rod directly drives the fixing frame 8 to move up and down, thereby realizing the precise adjustment of the height of the nozzle 9. The setting that the cylinder is fixed on the transverse plate 4 ensures the stable installation of the power source and is also convenient for maintenance and replacement.

[0046] Combined with the previous description, the entire system achieves efficient cleaning of the honeycomb filter layer 12 in all directions and at multiple angles through the lateral movement of the sliding plate 2, the left and right lateral movement of the transverse plate 4, the up and down driving of the push mechanism 7, and the smooth guidance of the guide column 6. The position adjustment of the nozzle 9 can not only get closer to or enter the through hole, but also ensure the optimization of the flushing distance, thereby improving the cleaning effect and efficiency.

[0047] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
