Description

Technical Field

[0001] This application belongs to the field of wastewater treatment technology, specifically relating to an online automatic flushing device for inclined tubes in sedimentation tanks. Background Technology

[0002] In the wastewater treatment process of urban wastewater treatment plants, the supernatant after separation in the secondary sedimentation tank flows into the inclined tube sedimentation tank for further treatment of recalcitrant organic matter, inorganic substances such as nitrogen and phosphorus, as well as microorganisms such as bacteria and viruses. However, in summer, due to the high ambient temperature and the high nitrogen and phosphorus content in the water of the inclined tube sedimentation tank, a large amount of green algae or deposits easily grow on the inclined tubes, effluent trough, and water surface. This not only adversely affects the sludge-water separation effect but also damages the overall aesthetics.

[0003] Typically, wastewater treatment plants periodically shut down or reduce production to drain the wastewater from the sedimentation tank to the lower part of the inclined tube. Workers then use high-pressure water guns to clean the algae and other substances that have grown on the inclined tube. However, this operation presents a challenge: shutting down or reducing production, especially for municipal wastewater treatment plants where the annual wastewater volume remains relatively stable, makes reducing production extremely difficult, and shutting down is almost impossible. This leads to a continuous increase in algae and other deposits on the inclined tube, causing blockages and severely reducing the efficiency of the inclined tube sedimentation tank.

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0037] See also Figure 1-5 As shown, according to an embodiment of this application, an online automatic flushing device for inclined tubes in a sedimentation tank is provided. The automatic flushing device 1 is installed on a sedimentation tank 2, and a plurality of inclined tubes 3 are spaced apart inside the sedimentation tank 2. The automatic flushing device 1 includes:

[0038] The main truss 11 is rotatably mounted on the sedimentation tank 2;

[0039] A flushing assembly 12 is mounted on the main frame 11 and is used to flush the inclined tube 3. The flushing assembly 12 includes:

[0040] Pump body 121 is mounted on the main frame 11 and located below the liquid surface of the sedimentation tank 2;

[0041] A flushing distribution pipe 122 is provided on the main frame 11 and located below the liquid surface of the sedimentation tank 2. A water supply pipe 123 is provided between the flushing distribution pipe 122 and the pump body 121.

[0042] A flushing nozzle 124 is spaced apart on the flushing distribution pipe 122;

[0043] The controller is mounted on the main frame 11, and the flushing nozzle 124 and the pump body 121 are electrically connected to the controller.

[0044] Specifically, the main truss 11 is made of high-strength steel to ensure a stable structure even during long-term operation and in complex environments. The main truss 11 supports and fixes the flushing assembly 12, which is rolled on the sedimentation tank 2. During operation, it drives the flushing assembly 12 to roll back and forth on the sedimentation tank 2, achieving more efficient flushing of the inclined pipe 3. The pump body 121 is mounted on the main truss 11 and positioned below the liquid surface in the sedimentation tank 2, allowing it to efficiently draw water using the 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 high speed, rapidly drawing in the clear water from the upper part of the sedimentation tank 2 and pressurizing it to form a high-pressure water flow. To reduce the impact of vibration generated by the pump body 121 during operation on other components of the equipment, a rubber vibration damping joint is installed at the outlet of the pump body 121. This joint has good flexibility and buffering performance, effectively absorbing vibration energy and preventing the transmission of vibration through the water supply pipe 123, thereby ensuring the stable operation of the entire flushing system.

[0045] The flushing distribution pipe 122 is mounted on the main frame 11 and located below the liquid surface of the sedimentation tank 2. It is connected to the pump body 121 via a water supply pipe 123. The water supply pipe 123 is made of corrosion-resistant, high-strength pipe material. The shape of the flushing distribution pipe 122 is flexibly adjusted 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 to 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 mounted on the main frame 11. It employs advanced microprocessor technology, possessing powerful data processing and control capabilities. The controller is electrically connected to the flushing nozzles 124 and the pump body 121 via wires. In actual operation, operators can flexibly set parameters such as the flushing interval, flushing duration, and spray angle of the flushing nozzles 124 on the controller's operating interface, based on the growth rate of algae and attached organisms on the inclined tube 3 under different seasons and water quality conditions. For example, during the high-temperature period in summer, when algae multiply rapidly, the flushing interval can be set to a shorter cycle, such as once a day; while in winter, when algae growth is slow, the flushing interval can be extended to once every three days. When the set flushing time is reached, the controller automatically sends a start signal to the pump body 121, which then begins to work, drawing clean water and pressurizing it. Simultaneously, the controller sends instructions to the flushing nozzles 124 according to preset parameters, adjusting their spray angle to achieve efficient and precise flushing of the inclined tube 3.

[0047] This automatic flushing equipment 1 can achieve efficient, intelligent and safe flushing of the inclined tube 3. There is no need to stop or reduce production during the flushing process. It not only improves the flushing effect, but also greatly reduces labor costs and safety risks, and ensures the stable operation of the sedimentation tank 2.

[0048] The flushing nozzle 124 is an electrically operated rotary nozzle.

[0049] Specifically, the rinsing nozzle 124 is an electrically driven rotating nozzle, which can rotate 360 ​​degrees omnidirectionally via a built-in micro motor. This feature greatly expands the rinsing range, enabling more comprehensive coverage of all surfaces of the inclined tube 3. Compared to traditional fixed nozzles, the electrically driven rotating nozzle eliminates rinsing dead zones, ensuring that every part of the inclined tube 3 is precisely impacted by the high-pressure water flow.

[0050] In actual operation, the controller precisely regulates the operation of the electric rotary nozzle. When the flushing program is started, the controller not only sends a start signal to the pump body 121, but also sends instructions to the electric rotary nozzle according to preset parameters to control its rotation speed and angle. For example, when algae are heavily attached in certain areas of the inclined tube 3, the operator can set the rotation speed of the corresponding electric rotary nozzle in that area to be slower and the residence time to be longer, so that the high-pressure water flow can flush away dirt for a longer time and with high intensity, thereby more effectively removing stubborn deposits.

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

[0052] Specifically, the support frame 13 is made of sturdy and durable metal, possessing excellent strength and corrosion resistance, enabling long-term stable operation in the humid environment of the sedimentation tank 2. Its first end is firmly mounted on the main truss 11 using welding or high-strength bolts, ensuring a tight connection and withstanding 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 surface of the sedimentation tank 2, providing stable and reliable support for the pump body 121 and the water supply pipeline 123.

[0053] The pump body 121 is fixedly mounted on the support frame 13, enabling it to stably draw clean water from the sedimentation tank 2. This ensures that the pump body 121 can efficiently draw water by fully utilizing the liquid level difference, while also preventing any impact on the pumping effect due to shaking or displacement during operation. The water supply pipeline 123 is also laid on the support frame 13, tightly connecting the pump body 121 to the flushing distribution pipe 122 along the structural direction of the support frame 13. The water supply pipeline 123 is fixed to the support frame 13 using a specially designed pipe clamp. The clamp not only firmly secures the pipeline, preventing displacement under water flow impact, but also provides a certain buffering effect, reducing the impact of pipeline vibration on the support frame 13 and other components.

[0054] The support frame 13 is provided with a coupling seat 14, and the pump body 121 is disposed 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. The pump body 121 is set 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 is running, the coupling seat 14 can effectively disperse the vibration and impact force generated by the pump body 121, reduce the impact on the support frame 13, and also help maintain the operational stability of the pump body 121, ensuring that it can stably draw clean water from the sedimentation tank 2.

[0056] A guide rod 15 is provided between the main 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 truss 11 and the coupling seat 14. The guide rod 15 is made of high-strength and corrosion-resistant metal, and its two ends are firmly connected to the main truss 11 and the coupling seat 14, respectively. The surface of the guide rod 15 is precision machined to ensure good straightness and smoothness. The pump body 121 is slidably connected to the guide rod 15. A sliding sleeve adapted to the guide rod 15 is provided on the pump body 121. The inside of the sliding sleeve is made of a special wear-resistant material to ensure that the pump body 121 slides smoothly and stably on the guide rod 15. When the pump body 121 needs to be inspected, the staff can use professional lifting tools, such as a small electric hoist or a manual chain hoist, to connect the hook to the lifting point on the pump body 121. Then, the lifting tools are started, and the pump body 121 will be slowly lifted from below the liquid surface of the sedimentation tank 2 along the guide rod 15. The guide rod 15 provides precise guidance for the lifting process of the pump body 121, preventing the pump body 121 from shaking or shifting during the lifting process, ensuring that it can be safely and smoothly lifted to a position that is easy to maintain, improving the maintenance efficiency of the pump body 121, and reducing maintenance time and difficulty.

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

[0059] The movable wheel set 5 includes:

[0060] The drive wheel 51 is disposed on the first end of the bottom of the main truss 11 and is located on the guide rail 4;

[0061] The driven wheel is disposed on the second end of the bottom of the main frame truss 11 and is located on the guide rail 4;

[0062] A drive component 52 is disposed on the main frame 11 and connected to the drive wheel 51.

[0063] Specifically, the guide rails 4 installed on both sides of the top of the sedimentation tank 2 are made of high-strength steel, and their surfaces are finely polished and rust-proofed to ensure that the stability of the equipment's movement will not be affected by wear, corrosion, or other factors during long-term use. The guide rails 4 are tightly integrated with the sedimentation tank 2, providing a stable and precise running track for the moving wheel assembly 5.

[0064] The main truss 11 is equipped with a set of movable wheels 5 at its bottom, enabling it to move flexibly on the track. The drive wheel 51 is located at the first end of the bottom of the main truss 11, resting on the guide rail 4. The drive wheel 51 is made of a wear-resistant, high-strength alloy, and its surface is designed with special anti-slip patterns to increase friction with the guide rail 4, ensuring that slippage does not occur during operation. The bearings of the drive wheel 51 are high-precision, low-friction products, ensuring smooth and stable rotation of the drive wheel 51.

[0065] The driven wheel is located at the second end of the bottom of the main truss 11, also on the guide rail 4. The driven wheel and the drive wheel 51 cooperate to support the weight of the main truss 11 and ensure the balance and stability of the main truss 11 during movement. The structure of the driven wheel is similar to that of the drive wheel 51, but its main function is to follow and provide auxiliary support.

[0066] The drive unit 52 is mounted on the main truss 11 and is tightly connected to the drive wheel 51. The drive unit 52 typically uses a combination of a motor and a reducer. When the equipment needs to be moved, the controller sends a command to the drive unit 52, and the motor inside the drive unit 52 starts to run. The reducer converts the high-speed rotation of the motor into the low-speed, high-torque rotation of the drive wheel 51, thereby driving the main truss 11 to move smoothly along the guide rail 4.

[0067] In actual operation, when it is necessary to flush the inclined tubes 3 in different areas of the sedimentation tank 2, the controller controls the direction and speed of the drive component 52 according to the preset program or the operator's instructions. For example, when it is necessary to move from one side of the sedimentation tank 2 to the other, the drive component 52 drives the drive wheel 51 to rotate in the forward or reverse direction, and the driven wheel rolls accordingly, so that the main frame 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 accuracy of the equipment operation.

[0068] Limit switches are provided on both sides of the guide rail 4, and the limit switches are electrically connected to the controller.

[0069] Specifically, limit switches are installed on both sides of the guide rail 4. These limit switches are electrically connected to the controller, providing a solid guarantee for the safe and stable operation of the equipment. The limit switches are high-sensitivity, high-reliability products capable of accurately detecting the position of the main truss 11. When the main truss 11 moves on the guide rail 4, the limit switches quickly sense the positional change as it approaches the ends of the guide rail 4. For example, when the drive component 52 drives the drive wheel 51, causing the main truss 11 to move to one side along the guide rail 4, and it is about to reach the end of the guide rail 4, the limit switch on that side immediately captures this information and quickly transmits the signal to the controller. Upon receiving the signal, the controller immediately issues a command to stop the operation of the drive component 52, causing the drive wheel 51 to stop rotating, thus allowing the main truss 11 to stop precisely within the safe range of the guide rail 4. This process ensures that the main truss 11 will not run off the guide rail 4 due to excessive movement, avoiding equipment damage and potential safety accidents. Furthermore, baffles are installed on both sides of the guide rail; when the limit switches fail, the probability of derailment is reduced, improving safety.

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

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

[0072] Specifically, the main truss 11 is equipped with a support plate made of thick metal sheet. The shape of the support plate is adapted to the load-bearing requirements of the main truss 11, typically rectangular or rectangular. The main function of the support plate is to provide a stable load-bearing platform for various equipment and components installed on the main truss 11. For example, important components such as controllers can be securely placed on the support plate, which effectively distributes the weight of these components, ensuring that the structural stability of the main truss 11 is not affected. At the same time, the support plate provides a spacious and flat operating space for the installation and maintenance of these components, facilitating wiring, debugging, and troubleshooting.

[0073] Guardrails are installed on both sides of the main truss 11 and the support plate. These guardrails are welded from sturdy and durable metal tubing. On one hand, the guardrails increase the overall rigidity of the main truss 11, making the structure more stable when subjected to various external forces. On the other hand, and more importantly, the guardrails play a crucial safety protection role. When operators are performing equipment operation, maintenance, or repair work on the main truss 11, the guardrails effectively prevent accidental falls, ensuring the personal safety of the workers. For example, when workers are standing on the main truss 11 adjusting controller parameters, repairing the drive component 52, or using lifting tools to maintain the pump body 121, the guardrails on both sides prevent falls caused by worker negligence or operational errors.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application.
