Description

Technical Field

[0001] This application belongs to the technical field of sewage treatment, and particularly relates to an on-line automatic flushing device for inclined tubes in a sedimentation tank. Background Art

[0002] In the sewage treatment process of urban sewage plants, the supernatant separated by the secondary sedimentation tank will flow into the inclined tube sedimentation tank to further treat refractory organic matter, inorganic matter such as nitrogen and phosphorus, and microorganisms such as bacteria and viruses. However, in summer, due to the high environmental temperature and the rich nitrogen and phosphorus nutrients in the water of the inclined tube sedimentation tank, a large amount of green algae or attachments are likely to grow on the inclined tubes, the effluent trough and the water surface. This not only has an adverse effect on the sediment-water separation effect, but also destroys the overall aesthetics.

[0003] Generally, sewage plants will take the way of regular production suspension or production reduction, empty the sewage in the sedimentation tank to the lower part of the inclined tubes, and then arrange workers to use high-pressure water guns to clean the green algae and other substances growing on the inclined tubes. However, there is a difficulty in this operation, that is, production suspension or production reduction. Especially for municipal sewage treatment plants, the annual water volume is basically maintained in a stable state, it is extremely difficult to reduce production, and it is almost impossible to suspend production. This makes the green algae and other attachments on the inclined tubes increase continuously, thereby causing blockage of the inclined tubes and seriously weakening the use efficiency of the inclined tube sedimentation tank.

[0036] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] Referring to Figures 1-5 As shown, according to an embodiment of the present application, an on-line automatic flushing device for inclined tubes of a sedimentation tank is provided. The automatic flushing device 1 is arranged on the sedimentation tank 2. A plurality of inclined tubes 3 are arranged at intervals in the sedimentation tank 2. The automatic flushing device 1 includes:

[0038] A mainframe truss 11, which is rollingly arranged on the sedimentation tank 2;

[0039] A flushing assembly 12, which is arranged on the mainframe truss 11. The flushing assembly 12 is used to flush the inclined tubes 3. The flushing assembly 12 includes:

[0040] A pump body 121, which is arranged on the mainframe truss 11 and is located below the liquid level of the sedimentation tank 2;

[0041] A flushing distribution pipe 122, which is arranged on the mainframe truss 11 and is located below the liquid level of the sedimentation tank 2. A water supply pipeline 123 is arranged between the flushing distribution pipe 122 and the pump body 121;

[0042] Flushing nozzles 124, which are arranged at intervals on the flushing distribution pipe 122;

[0043] A controller, which is arranged on the mainframe truss 11. The flushing nozzles 124 and the pump body 121 are electrically connected to the controller.

[0044] Specifically, the mainframe truss 11 is made of high-strength steel to ensure that it can still maintain a stable structure under long-term operation and complex environments. The mainframe truss 11 is used to support and fix the flushing assembly 12. It is rollingly installed on the sedimentation tank 2 and can drive the flushing assembly 12 to reciprocally roll on the sedimentation tank 2 during use to realize the flushing of the inclined tubes 3, making the flushing more efficient. The pump body 121 is installed on the mainframe truss 11 and is located below the liquid level of the sedimentation tank 2, enabling the pump body 121 to efficiently draw water by virtue of the liquid level difference of the clear water in the sedimentation tank 2. When the controller issues a start command, the impeller inside the pump body 121 rotates at a high speed, quickly sucking the clear water above in the sedimentation tank 2 and pressurizing it to form a high-pressure water flow. In order to reduce the influence of the vibration generated during the operation of the pump body 121 on other components of the equipment, a rubber shock-absorbing joint is installed at the outlet of the pump body 121. This joint has good flexibility and buffering performance, can effectively absorb the vibration energy, and prevent the vibration from being transmitted through the water supply pipeline 123, thereby ensuring the stable operation of the entire flushing system.

[0045] The flushing distribution pipe 122 is arranged on the main machine truss 11 and is located below the liquid level of the sedimentation tank 2. It is connected to the pump body 121 through the water supply pipeline 123. The water supply pipeline 123 is made of corrosion-resistant and high-strength pipe materials. The flushing distribution pipe 122 flexibly adjusts its shape according to the shape of the sedimentation tank 2 and the distribution of the inclined tubes 3 to achieve uniform flushing of the inclined tubes 3. The flushing nozzles 124 are evenly distributed on the flushing distribution pipe 122 to ensure that the flushing range can cover all the inclined tubes 3. Their supports are firmly fixed on the flushing distribution pipe 122 by welding to ensure that they will not loosen under the impact of high-pressure water flow.

[0046] The controller is installed on the main machine truss 11. It adopts advanced microprocessor technology and has powerful data processing and control capabilities. The controller is electrically connected to the flushing nozzles 124 and the pump body 121 through wires. During actual operation, operators can flexibly set parameters such as the flushing time interval, the flushing duration, and the spraying angle of the flushing nozzles 124 on the operation interface of the controller according to the growth rate of algae and attachments on the inclined tubes 3 under different seasons and different water quality conditions. For example, during the high-temperature period in summer, when algae reproduce rapidly, the flushing time interval can be set to a shorter cycle, such as once a day; while in winter, when algae grow slowly, the flushing time interval can be extended to once every three days. When the set flushing time arrives, the controller will automatically send a start signal to the pump body 121, and the pump body 121 starts to work, pumping clear water and pressurizing it. At the same time, the controller sends instructions to the flushing nozzles 124 according to the preset parameters to adjust their spraying angles to achieve efficient and precise flushing of the inclined tubes 3.

[0047] This automatic flushing device 1 can achieve efficient, intelligent, and safe flushing of the inclined tubes 3. During the flushing process, there is no need to stop production or reduce production, which not only improves the flushing effect but also greatly reduces the labor cost and safety risks, ensuring the stable operation of the sedimentation tank 2.

[0048] The flushing nozzle 124 is an electric rotating nozzle.

[0049] Specifically, the flushing nozzle 124 is an electric rotating nozzle, which is driven by a built-in micro motor and can rotate 360 degrees in all directions. This characteristic greatly expands the flushing range and can more comprehensively cover all surfaces of the inclined tubes 3. Compared with traditional fixed nozzles, the electric rotating nozzle can eliminate flushing dead corners and ensure that every part of the inclined tubes 3 can be accurately impacted by high-pressure water flow.

[0050] During the actual working process, the controller precisely regulates the operation of the electric rotary nozzle. When starting the flushing program, the controller not only sends a start signal to the pump body 121 but also sends instructions to the electric rotary nozzle according to the preset parameters to control its rotation speed and angle. For example, when algae attachment is relatively serious in certain areas of the inclined tube 3, the operator can set a slower rotation speed and a longer residence time for the electric rotary nozzle corresponding to this area in the controller, so that the high-pressure water flow can scour the dirt for a long time and with high intensity, thereby more effectively removing stubborn attachments.

[0051] It further includes a support frame 13. The first end of the support frame 13 is arranged on the main machine truss 11, and the second end of the support frame 13 is located below the liquid level of the sedimentation tank 2. The pump body 121 and the water supply pipeline 123 are arranged on the support frame 13.

[0052] Specifically, the support frame 13 is made of a strong and durable metal material, with excellent strength and corrosion resistance, and can operate stably in the humid environment of the sedimentation tank 2 for a long time. Its first end is firmly installed on the main machine truss 11, and the installation method is welding or high-strength bolt connection to ensure a tight combination with the main machine truss 11 and can withstand various forces generated during the operation of the pump body 121 and the water supply pipeline 123. The second end of the support frame 13 extends below the liquid level of the sedimentation tank 2 to provide stable and reliable support for the pump body 121 and the water supply pipeline 123.

[0053] The pump body 121 is fixedly arranged on the support frame 13, enabling the pump body 121 to stably draw clear water from the sedimentation tank 2. This not only ensures that the pump body 121 can make full use of the liquid level difference to efficiently draw water but also ensures that the pumping effect will not be affected by shaking or displacement during operation. The water supply pipeline 123 is also laid on the support frame 13 and is tightly connected to the flushing distribution pipe 122 along the structural trend of the support frame 13. The fixing method of the water supply pipeline 123 on the support frame 13 is a special pipe clamp. The pipe clamp can not only firmly fix the pipeline to prevent it from displacing under the impact of water flow but also has a certain buffering effect to reduce the influence of pipeline vibration on the support frame 13 and other components.

[0054] A coupling seat 14 is arranged on the support frame 13, and the pump body 121 is arranged on the coupling seat 14.

[0055] Specifically, a coupling seat 14 is provided on the support frame 13. The coupling seat 14 is firmly fixed to the support frame 13 by welding or other reliable connection methods, which not only ensures the stability of the pump body 121 after installation but also facilitates subsequent maintenance and repair work. The pump body 121 is arranged on the coupling seat 14, making the connection between the pump body 121 and the support frame 13 more stable. When the pump body 121 operates, the coupling seat 14 can effectively disperse the vibration and impact force generated by the pump body 121, reduce the influence on the support frame 13, and at the same time contribute to maintaining the operating stability of the pump body 121, ensuring that it can stably extract clear water from the sedimentation tank 2.

[0056] A guide rod 15 is provided between the main machine truss 11 and the coupling seat 14, and the pump body 121 is slidably connected to the guide rod 15.

[0057] Specifically, a guide rod 15 is provided between the main machine truss 11 and the coupling seat 14. The guide rod 15 is made of a high-strength and corrosion-resistant metal material, and its two ends are firmly connected to the main machine truss 11 and the coupling seat 14 respectively. The surface of the guide rod 15 is precisely processed to ensure its good straightness and smoothness. The pump body 121 is slidably connected to the guide rod 15, and a sliding sleeve adapted to the guide rod 15 is provided on the pump body 121. The inside of the sliding sleeve uses special wear-resistant materials to ensure that the pump body 121 slides smoothly and stably on the guide rod 15. When the pump body 121 needs to be repaired, the staff can connect the hook to the lifting point on the pump body 121 through a professional lifting tool, such as a small electric hoist or a manual chain hoist. Then, start the lifting tool, and the pump body 121 will be slowly lifted from below the liquid level of the sedimentation tank 2 along the guide rod 15. The guide rod 15 provides accurate guidance for the lifting process of the pump body 121, avoiding the pump body 121 from shaking or shifting during the lifting process, ensuring that it can be safely and smoothly lifted to a position convenient for repair, improving the repair efficiency of the pump body 121, and reducing the repair time and difficulty.

[0058] Guide rails 4 are provided on both sides of the top of the sedimentation tank 2, and a moving wheel set 5 is provided at the bottom of the main machine truss 11 and above the guide rails 4.

[0059] The moving wheel set 5 includes:

[0060] A driving wheel 51, which is arranged at the first end of the bottom of the main machine truss 11 and is located on the guide rail 4;

[0061] A driven wheel, which is arranged at the second end of the bottom of the main machine truss 11 and is located on the guide rail 4;

[0062] A driving member 52, which is arranged on the main machine truss 11 and is connected to the driving wheel 51.

[0063] Specifically, the guide rails 4 provided on both sides at the top of the sedimentation tank 2 are made of high-strength steel, and their surfaces are finely polished and anti-rust treated to ensure that during long-term use, the moving stability of the equipment will not be affected by factors such as wear and corrosion. The guide rails 4 are closely combined with the sedimentation tank 2, providing a stable and precise running track for the moving wheel set 5.

[0064] The moving wheel set 5 is installed at the bottom of the main machine truss 11 and can move flexibly on the track. Among them, the driving wheel 51 is arranged at the first end of the bottom of the main machine truss 11 and is located on the guide rail 4. The material of the driving wheel 51 is selected as wear-resistant and high-strength alloy, and its wheel surface is designed with special anti-slip patterns to increase the friction with the guide rail 4 and ensure that there is no slipping phenomenon during operation. The bearing of the driving wheel 51 adopts high-precision and low-friction products to ensure the smoothness and stability of the driving wheel 51 during rotation.

[0065] The driven wheel is arranged at the second end of the bottom of the main machine truss 11 and is also located on the guide rail 4. The driven wheel and the driving wheel 51 cooperate with each other to jointly support the weight of the main machine truss 11 and ensure the balance and stability of the main machine truss 11 during movement. The structure of the driven wheel is similar to that of the driving wheel 51, but it mainly plays a role of following and auxiliary support in function.

[0066] The driving member 52 is arranged on the main machine truss 11 and is closely connected to the driving wheel 51. The driving member 52 usually adopts a combination of a motor and a speed reducer. When the equipment needs to be started to move, the controller sends an instruction to the driving member 52, and the motor inside the driving member 52 starts to operate. The speed reducer converts the high-speed rotation of the motor into the low-speed and high-torque rotation of the driving wheel 51, thereby driving the main machine truss 11 to move smoothly along the guide rail 4.

[0067] During actual operation, when the inclined tubes 3 in different areas of the sedimentation tank 2 need to be flushed, the controller controls the rotation direction and speed of the driving member 52 according to the preset program or the operator's instruction. For example, when it is necessary to move from one side of the sedimentation tank 2 to the other side, the driving member 52 drives the driving wheel 51 to rotate forward or backward, and the driven wheel rolls accordingly, and the main machine truss 11 moves smoothly along the guide rail 4. During the movement, the close cooperation between the guide rail 4 and the moving wheel set 5 ensures the stability and precision of the equipment operation.

[0068] Travel switches are arranged on both sides of the guide rail 4, and the travel switches are electrically connected to the controller.

[0069] Specifically, travel switches are provided on both sides of the guide rail 4. The travel switches are electrically connected to the controller, providing a solid guarantee for the safe and stable operation of the equipment. The travel switches adopt products with high sensitivity and high reliability, and can accurately detect the position of the main machine truss 11. When the main machine truss 11 moves on the guide rail 4, once it approaches both ends of the guide rail 4, the travel switches will quickly sense the position change of the main machine truss 11. For example, when the driving member 52 drives the driving wheel 51 to drive the main machine truss 11 to move along the guide rail 4 to one side and is about to reach the end of the guide rail 4, the travel switch on this side will immediately capture this information and quickly transmit the signal to the controller. After receiving the signal, the controller will immediately issue an instruction to stop the operation of the driving member 52, so that the driving wheel 51 stops rotating, so that the main machine truss 11 stops accurately within the safe range of the guide rail 4. This process ensures that the main machine truss 11 will not rush out of the guide rail 4 due to excessive movement, avoiding equipment damage and possible safety accidents. Moreover, baffles are provided on both sides of the guide rail. When the travel switch fails, the derailment probability can be reduced and the safety can be improved.

[0070] A support plate is provided on the main machine truss 11.

[0071] Guardrails are provided on the main machine truss 11 and on both sides of the support plate.

[0072] Specifically, a support plate is provided on the main machine truss 11. The support plate is made of thick metal plates, and its shape is adapted to the load-bearing requirements of the main machine truss 11, usually rectangular or square. The main function of the support plate is to provide a stable load-bearing platform for various equipment and components installed on the main machine truss 11. For example, important components such as the controller can be stably placed on the support plate. The support plate can effectively disperse the weights of these components, ensuring that the structural stability of the main machine truss 11 is not affected. At the same time, when installing and maintaining these components, the support plate provides a spacious and flat operating space, facilitating the staff to carry out wiring, debugging, and troubleshooting and other work.

[0073] On the main machine truss 11 and on both sides of the support plate, guardrails are provided. The guardrails are welded from strong and durable metal pipes. The setting of the guardrails increases the overall rigidity of the main machine truss 11 on the one hand, making its structure more stable when bearing various external forces. On the other hand, and more importantly, the guardrails play a crucial safety protection role. When the operator performs equipment operation, maintenance, and overhaul and other work on the main machine truss 11, the guardrails can effectively prevent personnel from accidentally falling and ensure the personal safety of the staff. For example, when the staff stands on the main machine truss 11 to adjust the controller parameters, overhaul the driving member 52, or perform maintenance on the pump body 121 with the help of lifting tools, the guardrails on both sides prevent the falling accident caused by the negligence or operation error of the staff.

[0074] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application. The above is only the preferred implementation manner of the present application. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and variations can be made without departing from the technical principle of the present application, and these improvements and variations should also be regarded as within the protection scope of the present application.
