Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an intelligent sludge discharge and storage system for a sewage treatment plant. Background Art

[0002] In current sewage treatment plant operations, the sludge drainage process generally adopts a relatively traditional management model. Specifically, sewage treatment plants are usually equipped with multiple sedimentation tanks, each of which is equipped with a sludge pump to extract the sludge from the sedimentation tank and discharge it into the sludge storage tank.

[0003] However, existing sludge pump operations rely on manual on-site control to start and stop. This not only results in a low degree of automation for the entire sludge drainage and storage system, but also low efficiency, making it difficult to achieve accurate sludge management. Secondly, due to the lack of effective remote monitoring methods, staff need to frequently travel between the control room and various sedimentation tanks and sludge storage tanks to check liquid levels. Considering that sewage treatment plants often cover a large area, this working mode not only consumes a large amount of manpower, but also seriously affects work efficiency and the real-time nature of data feedback due to long journeys. Therefore, the existing sludge drainage and storage control system needs to be improved in terms of ease of operation, degree of automation, and work efficiency. Utility Model Content

The pump structure and the liquid level gauge structure are electrically connected to each other through a PLC controller and an external power supply.

[0006] Preferably, a one-way valve is installed inside the pipeline between the pump structure and the confluence area.

[0007] Preferably, mud outlet pipes are installed at the output ends of the mud storage tank area 1 and the mud storage tank area 2.

[0020] In the present invention, a one-way valve 7 is preferably installed inside the pipe between the pump structure 9 and the confluence area 3. The main function of the one-way valve 7 in the intelligent sludge drainage and storage remote centralized control system is to prevent sludge backflow and ensure the direction of sludge flow. It is installed on the pipe connecting the confluence area 3 and the sedimentation tank, ensuring that sludge can only flow from the sedimentation tank to the confluence area 3 and cannot flow back, thereby ensuring the normal operation of the system and achieving effective sludge drainage and storage.

[0024] In the present utility model, preferably, pump one 901 and pump two 902 are both installed inside the first-phase sedimentation tank 401, pump three 903, pump four 904, pump five 905 and pump six 906 are all installed inside the second-phase sedimentation tank 402, pump seven 907, pump eight 908, pump nine 909 and pump ten 910 are all installed inside the third-phase sedimentation tank 403, and the PLC controller 8 controls the start and stop of these pumps according to the liquid level conditions of the sedimentation tank and the sludge storage tank, thereby adjusting the sludge extraction and discharge volume to ensure efficient and stable operation of the system.

[0025] In the present invention, preferably, the liquid level gauge structure 2 includes a liquid level gauge 1 201 , a liquid level gauge 202 and a liquid level gauge 3 203 .

[0026] In the present invention, preferably, liquid level gauge 1 201 is installed inside the second zone 102 of the sludge storage tank, liquid level gauge 202 is installed inside the first zone 101 of the sludge storage tank, and three liquid level gauges 203 are provided. The three liquid level gauges are respectively installed inside the first phase sedimentation tank 401, the second phase sedimentation tank 402 and the third phase sedimentation tank 403. The liquid level gauges are respectively installed at different positions of the sedimentation tank and the sludge storage tank to monitor the liquid level changes in each area in real time. The liquid level gauge feeds back the monitored liquid level information to the PLC controller 8 to provide data support for the control system. The PLC controller 8 determines whether the sludge extraction and discharge volume are reasonable based on the information fed back by the liquid level gauge, and controls the start and stop of each pump to ensure efficient and stable operation of the system.

[0027] Usage process: Step 1: Monitoring the liquid level: Liquid level gauge 1 201 is installed inside the first area 101 of the sludge storage tank to monitor the sludge liquid level in this area; Liquid level gauge 202 is installed inside the second area 102 of the sludge storage tank to monitor the sludge liquid level in this area; Liquid level gauge 3 203 is installed inside the first, second and third phase sedimentation tanks 403 respectively to monitor the sludge liquid level of each sedimentation tank; All liquid level gauges will feed back the monitored liquid level data to the PLC controller 8 in real time;

[0028] Step 2: Analyze data: The PLC controller 8 analyzes the storage amount of sludge in the first and second sludge storage tanks and whether it needs to be discharged based on the data fed back by the liquid level gauges 1 201 and 2; the PLC controller 8 analyzes the storage amount of sludge in each sedimentation tank and whether it needs to be extracted based on the data fed back by the liquid level gauge 3 203;

[0029] Step three: Control the start and stop of the pumps: The PLC controller 8 determines the amount of sludge in each sedimentation tank based on the feedback from the liquid level meter 3 203. If the liquid level is lower than the set value, the pumps 1 901, 2 902, 3 903, 4 904, 5 905, 6 906, 7 907, 8 908, 909 and 10 910 of the corresponding sedimentation tank are controlled to start and extract the sludge; if the liquid level continues to drop, it means that the sludge has been emptied, and the PLC controller 8 controls the sludge pumps of the sedimentation tank to stop working; the PLC controller 8 determines the storage amount of sludge in the sludge storage tank area 101 and area 2 based on the feedback from the liquid level meters 1 201 and 2. If the liquid level is higher than the set value, some sludge pumps are controlled to stop working to reduce the amount of sludge entering and avoid overflow; if the liquid level continues to rise, it means that the amount of sludge discharged is greater than the amount discharged, and the PLC controller 8 controls more sludge pumps to start and increase the amount of sludge entering to ensure the effective use of the sludge storage tank;

[0030] Step 4: Sludge flow: The sludge pumps of each sedimentation tank transport the extracted sludge to the confluence area 3 through the pipeline with a one-way valve 7; the confluence area 3 transports the sludge to the first and second sludge storage tanks through the mud inlet pipes 5;

[0031] Step 5: Adjust output: The PLC controller 8 determines the discharge demand of sludge in the first and second areas of the sludge storage tank according to the feedback of the liquid level gauges 1 201 and 2; when the liquid level is higher than the set value, the PLC controller 8 controls the opening and closing of the mud outlet pipe 6 to discharge the sludge.

[0032] Through the above steps, the system realizes the automatic extraction, storage and discharge of sludge, ensuring the efficient and stable operation of the sewage treatment plant.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
