Specific implementation manners

[0044] Embodiment

[0045] As Figure 10 shown, a mine water treatment production and operation integration control system includes the following modules:

[0046] Special treatment module, including a water treatment device for treating mine water and outputting purified water;

[0047] Intelligent sensing network for monitoring mine water parameters and data of the special treatment module;

[0048] Edge computing terminal for executing commands on the special treatment module and data transmission;

[0049] Production and operation platform, signal-connected to the intelligent sensing network and the edge computing terminal, for storing and integrating operation data, establishing a database model, correcting algorithms according to system data, and realizing dynamic adjustment of equipment start-stop combinations.

[0050] In this embodiment, the intelligent sensing network shall meet the mine explosion-proof certification standard, with an IP68 waterproof rating, and be adapted to the high humidity and dust environment of the mine.

[0051] Data transmission uses the SM4 national encryption algorithm to encrypt sensor data and a two-way identity authentication mechanism based on digital certificates.

[0052] In this embodiment, the intelligent sensing network includes a dual-ray densitometer, a mine-grade water quality detection module, an equipment status detection module, and a sludge discharge detection module. The dual-ray densitometer is arranged at the water inlet 22 of the water treatment tank 1 for real-time detection of the solid content of the feed slurry;

[0053] The mine - grade water quality detection module array includes a pH meter, a COD sensor, and a heavy metal ion monitor, which are used to detect the mine water inside the drainage chamber 5 of the water treatment device;

[0054] Among them, the measurement range of the pH meter is 0 - 14, the accuracy is ±0.1. Specifically, the Hach HQD series can be adopted, and its explosion - proof grade meets the ExdIMb standard; the COD sensor uses the ultraviolet spectroscopy method, and the detection limit is ≤5mg / L; the heavy metal ion monitor supports the simultaneous multi - parameter detection of Cu 2+ 、Zn 2+ 、Pb 2+ , and the detection limit is ≤0.1ppm; at the same time, a turbidity sensor can also be set, with a range of 0 - 1000NTU and supporting online self - cleaning.

[0055] In this embodiment, the equipment status detection module includes a vibration sensor, a temperature sensor, a rotational speed sensor, and a torque real - time monitor, which are used to monitor the operating parameters of the centrifuge 3 of the water treatment device;

[0056] The frequency response range of the vibration sensor is 10Hz - 10kHz, and the resolution is ±0.1m / s 2 ; the range of the torque real - time monitor is 0 - 500Nm, the accuracy is ±0.5%FS, and the output signal is 4 - 20mA.

[0057] In this embodiment, the sludge discharge detection module includes a sludge level radar sensor and a high - definition vision detection module, which are used to dynamically detect the sludge block capacity inside the sludge discharge chamber 4.

[0058] The sludge level radar sensor uses a 24GHz millimeter - wave radar, with a measurement range of 0 - 10m, supporting a temperature compensation algorithm and adapting to the temperature fluctuations in the mine environment (-20℃ to 60℃).

[0059] At the same time, a dual - ray densitometer can also be set at the water inlet 22 of the water treatment tank 1 to detect the solid content of the feed slurry in real - time (0 - 40%); the high - definition vision detection module includes a spectral camera and a multi - spectral light source, and extracts sludge block features through algorithms such as edge detection and grayscale analysis. Correspondingly, the production operation platform can classify defects (such as screw deformation detection, weld quality assessment) by using a convolutional neural network, and introduce improved networks such as U2Net and MRAU in some scenarios to enhance the dynamic feature capture ability.

[0060] At the same time, through the change of the grayscale value of the mine water detected by the high - definition vision detection module, the concentration of suspended solids in the mine water can be monitored, which is convenient for dynamically adjusting the chemical dosage.

[0061] Further, in this embodiment, the edge computing terminal includes a controller, an embedded AI chip, and a 5G gateway. The controller is used to execute the closed-loop control of the water treatment device. The embedded AI chip is used to run the centrifugal efficiency optimization algorithm in real time. The 5G gateway is used for low-latency data transmission between the intelligent sensor and the production operation platform.

[0062] Further, the controller adopts an industrial-grade PLC controller, and its control method adjusts the speed of the frequency conversion drive motor 21 of the centrifuge 3 based on the PID algorithm; according to the bin volume data of the mud level radar sensor, the start-stop threshold of the screw conveyor at the sludge discharge pipe 23 of the water treatment tank 1 is triggered.

[0063] The 5G gateway adopts an industrial gateway, and its communication method supports protocols such as Modbus / TCP, OPCUA, or MQTT. Specifically, the MQTT protocol can be used to interact with the data middle platform. The data packet encapsulation format is JSON, which is compatible with heterogeneous communication of industrial devices; the time-sensitive network (TSN) technology is adopted to ensure that the transmission delay of control instructions ≤ 10ms.

[0064] In this embodiment, the production operation platform includes a data middle platform, an intelligent algorithm engine, and a data operation management platform. The data middle platform includes a time series database, a spatial database, and a knowledge graph. The time series database is used to store the operation data of the water treatment device. The spatial database is used to establish the three-dimensional coordinate modeling of the pipeline / equipment. The knowledge graph is used to store the mine hydrogeological data;

[0065] Specifically, the time series database supports high-frequency writing, efficient compression storage, and time window aggregation analysis. In mine water treatment, it is used to store the real-time operation data of water treatment devices such as water treatment tank 1, pumping station, intelligent sensor network, etc., such as flow rate, pressure, water quality parameters, etc.; specific models can include InfluxDB, TDengine, TimescaleDB, etc., and adopt protocols such as HTTP API, MQTT / Modbus. The time series database adopts columnar storage + time sharding (such as Hypertable of TimescaleDB) to improve the compression rate and query efficiency; realize the mean and maximum value statistics of minutes / hours through time window functions (such as time_bucket); store by time partition, store recent hot data in SSD, and transfer historical cold data to low-cost HDD.

[0066] The spatial database supports the storage, query, and analysis of geospatial data, which is used to establish the three-dimensional coordinate model and spatial topological relationship of pipe networks and equipment, and assist in the layout optimization and emergency response of the mine water treatment system. The available models include PostGIS (based on PostgreSQL) or ArcGIS GeoDatabase, etc.; the available protocols include OGC standards (such as WKT, WKB) or GeoJSON. The modeling methods include three-dimensional coordinate extraction (extracting the coordinates of pipe network nodes from CAD drawings or point cloud data to construct a topological network), GIS toolchain (using QGIS or ArcGIS for spatial interpolation (such as Kriging method), hydrological simulation (such as groundwater flow model)), and BIM integration (combining the pipe network model with the Building Information Model (BIM) to achieve full life-cycle management).

[0067] The knowledge graph represents domain knowledge through a structured semantic network, which is used to integrate mine hydrogeological data (such as aquifer distribution, fault structure, historical water inrush events), and support intelligent reasoning and decision-making. The available tools include Neo4j or Apache Jena; the available protocols include RDF or OWL; during the construction of the knowledge graph, data can be obtained from the parameters of the intelligent sensing network, and the knowledge graph can be constructed based on the rule engine, which can be used for risk early warning of the operation of water treatment devices, etc.

[0068] In this embodiment, the intelligent algorithm engine includes a dehydration efficiency optimization model and a fault diagnosis system. The dehydration efficiency optimization model is based on the self-tuning of three parameters of the centrifuge 3 using LSTM. The fault diagnosis system uses vibration spectrum analysis and an expert rule base, and may also include sludge production prediction using the ARIMA + operating condition correction algorithm;

[0069] The inputs of the LSTM parameter self-tuning model include: real-time water quality data (pH, COD, turbidity); vibration spectrum characteristic values of the centrifuge 3 (peak frequency, harmonic energy ratio); the output is the optimized value of the separation factor (G);

[0070] The operating condition correction factors of the sludge production prediction model include: the load rate of the centrifuge 3 (current torque / rated torque); the mapping relationship between the chemical agent dosing concentration and the sludge specific resistance; the expert rule base of the fault diagnosis system includes: when the 2 × rotation frequency harmonic in the vibration spectrum exceeds the threshold, trigger the "bearing wear" early warning; when the slope of the temperature sensor data exceeds 0.5℃ / s, trigger the "overheat protection" shutdown instruction.

[0071] In this embodiment, the data operation and management platform includes a digital twin interface, a production scheduling module, and a cost analysis system. The digital twin interface is used to map the physical water treatment system in real time. The production scheduling module is used to dynamically adjust the start-stop combination of water treatment devices. The cost analysis system is used to comprehensively statistics on chemical agents, energy consumption, and labor.

[0072] The digital twin interface can use Siemens NXMCD, which is suitable for virtual modeling and real-time monitoring of water treatment devices (such as pumping stations and sedimentation tanks); physical device data (such as flow rate, pressure, temperature) is collected through sensors and transmitted to the virtual model via the Profinet / OPCUA protocol to achieve real-time status updates; the production scheduling module uses Rockwell Automation PlantPAx to collect device status (such as the current of centrifuge 3 and the valve opening) through an intelligent sensing network and dynamically adjusts the start-stop strategy in combination with energy consumption data; the cost analysis system uses the Fanpu chemical industry cost management system or SAP S / 4HANA CO-PA (Profitability Analysis).

[0073] When the centrifugal efficiency optimization algorithm is specifically applied, a bidirectional LSTM network structure is adopted, which includes 3 hidden layers, each layer contains 128 neurons, and the attention mechanism (Attention) is introduced to dynamically weight the feature importance of different time steps;

[0074] Input layer: includes real-time water quality data: pH value (0 - 14), COD concentration (0 - 5000 mg / L), turbidity (0 - 1000 NTU), heavy metal ion concentration (Cu 2+ / Zn 2+ / Pb 2+ , 0 - 10 ppm); equipment operation parameters: vibration spectrum of centrifuge 3 (energy distribution in the 10 Hz - 10 kHz frequency band), torque (0 - 500 Nm), rotational speed (0 - 3000 rpm), temperature (-20°C to 60°C); environmental parameters: mud solid content (0 - 40%), mud level height in the sludge discharge chamber 4 (0 - 10 m).

[0075] Output layer: includes the separation factor (G value): optimize the solid phase sedimentation efficiency by adjusting the rotational speed of centrifuge 3.

[0076] G = 1.118×10 -5 ×r×N 2 , where r is the radius of centrifuge 3 and N is the rotational speed;

[0077] Under normal conditions, the separation factor G can take a value of 2000. In the case of mine water with high suspended solids, the G value can be increased to 2500 to enhance the centrifugal force and accelerate the solid phase sedimentation.

[0078] Optimization logic and dynamic adjustment mechanism:

[0079] Feature engineering:

[0080] Perform FFT transformation on the vibration spectrum, and extract 12-dimensional features such as the proportion of the main frequency harmonic energy and the resonance peak offset; use a sliding window (5-minute window, 1-minute step) to statistically calculate the mean value, extreme value, and change rate of water quality parameters.

[0081] Online learning:

[0082] Embed it into the transfer learning framework. In the pre-training stage, use 100,000 sets of historical working condition data (covering different mine water qualities and equipment wear states); in the deployment stage, update the model weights through online incremental learning to adapt to water quality fluctuations and new working conditions.

[0083] Multi-objective optimization:

[0084] Meet the real-time water quality data of the clear water under the output conditions, and at the same time minimize the energy consumption (E = ∫(torque × rotational speed)dt).

[0085] Constraint condition: Vibration acceleration ≤ 5m / s 2 (Prevent equipment overload).

[0086] The edge computing terminal runs the optimization algorithm in real time through the embedded AI chip, with a response delay ≤ 50ms, and dynamically adjusts the output of the centrifuge 3 frequency converter.

[0087] The data middle platform stores the historical optimization records, and triggers the model retraining by comparing the actual parameters of the drainage with the predicted values (when the continuous 3 prediction errors > 5%).

[0088] The digital twin interface visualizes the operating status of the centrifuge 3, and supports manual intervention for fine-tuning of parameters (such as manually locking the rotational speed under emergency conditions);

[0089] When the equipment is in a sub-healthy state, the vibration sensor detects an increase in the harmonic energy at twice the rotational frequency (indicating bearing wear): the algorithm limits the maximum rotational speed to 80% of the rated value to avoid resonance risk. When the algorithm frequently triggers the rotational speed limit, it automatically associates with the fault diagnosis system to analyze the bearing wear level and generate a preventive maintenance work order.

[0090] Such as Figures 1 - 9As shown in the figure, the water treatment device includes several serially connected water treatment tanks 1. An annular intermediate treatment tank 2 is rotatably arranged inside the water treatment tank 1. A centrifuge 3 is arranged inside the water treatment tank 1, and the centrifuge 3 is used to drive the intermediate treatment tank 2 to rotate.

Two symmetrical sludge discharge ports 6 are opened outside the intermediate treatment tank 2, and the two sludge discharge ports 6 divide the intermediate treatment tank 2 into two symmetrical water treatment chambers 7. Looking from the rotation direction of the water treatment tank 1, a sealing plate 8 is arranged at the front end of the water treatment chamber 7; several filter membranes 9 are arranged at the rear end of the water treatment chamber 7. The mine water is filtered by the filter membranes 9 and then enters the inside of the water treatment chamber 7, enters the drainage chamber 5 through the bottom of the water treatment chamber 7, and is finally discharged from the bottom of the water treatment tank 1.

[0091] As Figures 1 - 9 shown in the water treatment device, an installation platform 10 is arranged at the lower inner side of the water treatment tank 1. The intermediate treatment tank 2 is rotatably arranged on the installation platform 10. The centrifuge 3 is arranged on the lower side of the installation platform 10, and the centrifuge 3 is used to drive the intermediate treatment tank 2 to rotate;

[0092] A drain port 11 is arranged at the bottom of the water treatment chamber 7. The water treatment chamber 7 communicates with the inside of the drainage chamber 5 through the drain port 11. A vertical drain pipe 12 is arranged at the bottom of the drainage chamber 5. The lower end of the drain pipe 12 is integrally formed with the bottom of the intermediate treatment tank 2. The upper end of the drain pipe 12 extends upward to the upper part of the drainage chamber 5. A drain hole 13 is arranged between the bottom of the drain pipe 12 and the lower side of the installation platform 10;

[0093] When the centrifuge 3 operates, it can drive the water treatment chamber 7 and the drain pipe 12 to rotate simultaneously.

[0094] The intermediate treatment tank 2 is arranged in a fitting manner with the installation platform 10. The centrifuge 3 is used to drive the intermediate treatment tank 2 to rotate, and the intermediate treatment tank 2 and the water treatment tank 1 are coaxially arranged.

[0095] As Figure 3 and Figure 5 shown, the bottom plate of the intermediate treatment tank 2 is a circular plate. Two water distributors 14 are arranged at the upper inner side of the intermediate treatment tank 2. The water distributors 14 include fixing plates and several convex blocks. The two water distributors 14 divide the upper part of the intermediate treatment tank 2 into two water inlet areas 15.

[0096] The water distributor 14 is arranged at the top of the inner layer of the intermediate treatment tank 2, and the water distributor 14 and the intermediate treatment tank 2 can be rotatably connected. By driving the water distributor 14 to rotate with a motor, the incoming water can be struck, promoting the efficient mixing of the mine water and the sedimentation agent.

[0097] As Figure 3 , Figure 6 and Figure 9 shown, a closing plate 16 is movably arranged outside the sludge discharge port 6. The closing plate 16 is configured with an electromagnet 17. The closing plate 16 and the intermediate treatment tank 2 are magnetically attracted by the electromagnet 17. A scraping plate 18 is arranged outside the closing plate 16. The outer side of the scraping plate 18 is in contact with the inner wall of the water treatment tank 1. The lower end of the closing plate 16 is bent outward to form a limiting ring 19. The closing plate 16 is used for sealing the sludge discharge port 6 and cleaning the side wall of the water treatment tank 1;

The limiting ring 19 is rotatably arranged inside the guiding groove. A driving motor 21 is arranged below the guiding ring 20. The output shaft of the driving motor 21 is provided with a driving gear. A limiting gear is arranged outside the limiting ring 19. The driving gear is meshed and connected with the limiting gear.

[0099] The closing plate 16 and the outer side wall of the intermediate treatment tank 2 are hermetically and fittingly arranged. Electromagnets 17 are arranged at the four corners of the closing plate 16. When the electromagnets 17 are energized, the closing plate 16 and the intermediate treatment tank 2 can be tightly magnetically attracted. When the driving motor 21 operates, it can drive the closing plate 16 and the intermediate treatment tank 2 to rotate relatively, so that the sludge discharge port 6 is opened.

[0100] As Figure 4 shown, a plurality of the filter membranes 9 are uniformly arranged along the arc direction of the water treatment cavity 7. The pore diameter of the filter membranes 9 gradually decreases from outside to inside;

[0101] The filter membranes 9 are arranged in an arc shape.

[0102] The filter membranes 9 can be detachably connected to the intermediate treatment tank 2, which is convenient for replacing the filter membranes 9. Specifically, the side edges of the filter membranes 9 can be connected with fixing strips, and the fixing strips can be inserted into the inner wall of the intermediate treatment tank 2.

[0103] As Figure 4 shown, the sealing plate 8 is an arc-shaped plate. The outer side of the sealing plate 8 is smoothly connected with the sludge discharge port 6. When the intermediate treatment tank 2 rotates, the sludge accumulates along the sealing plate 8 towards the sludge discharge port 6 under the action of centrifugal force. When the sludge discharge port 6 is opened, the sludge is discharged outwards from the sludge discharge port 6.

[0104] The sealing plate 8 can seal one end of the drainage cavity 5 and can also guide the sludge, so that the sludge flows along the sealing plate 8 towards the sludge discharge port 6.
