Furthermore, workers must troubleshoot each abnormal device and its cause, resulting in low efficiency. In particular, when the ultrafiltration device malfunctions, such as when the ultrafiltration membrane is clogged or damaged, the abnormality cannot be detected in time, causing water that does not meet the process standards to flow into the next device, affecting the progress of the water treatment project and ultimately affecting the quality of the effluent.

[0031] Example 1

[0032] This embodiment provides a control system for a modular coal mine underground water treatment device, such as... Figure 1 As shown, it includes a central processing unit 15, which is connected to a data acquisition module 20, a valve control module 16, an alarm module 18, a display screen 17, and a power supply module 19, respectively.

[0033] The data module is used to collect data from the water treatment device and transmit it to the central processing unit. The valve switching module is used to receive control signals sent by the central processing unit. The data acquisition module includes a third pressure sensor and a fourth pressure sensor. The valve switching control module includes a second valve and a third valve. The third pressure sensor and the fourth pressure sensor are used to acquire the pressure data of the inlet and outlet of the ultrafiltration device, respectively. The second valve and the third valve are installed on the pipes at both ends of the ultrafiltration device.

[0034] In specific implementation methods, such as Figure 2 As shown, the data acquisition module 20 also includes a first turbidity sensor 61, a second turbidity sensor 62, a third turbidity sensor 63, a fourth turbidity sensor 64, a first flow sensor 71, a second flow sensor 72, a third flow sensor 73, a fourth flow sensor 74, a fifth flow sensor 75, a first pressure sensor 81, a second pressure sensor 82, a third pressure sensor 83, a fourth pressure sensor 84, a fifth pressure sensor 85, a sixth pressure sensor 86, a first water quality sensor 101, a fifth turbidity sensor 65, a third water quality sensor 103, a sixth flow sensor 76, a first temperature sensor 12, an SDI sensor 13, an ORP sensor 14, and several level sensors. The switch valve control module 16 is also connected to the first switch valve 1, the third switch valve 3, the fourth switch valve 4, and the fifth switch valve 5. The switch valve control module 16 and the data acquisition module 20 will be described in detail below:

[0035] In a specific implementation, a level sensor is installed in the pre-sedimentation tank to monitor the water level data in real time and transmit the data to the central processing unit 15. The central processing unit 15 receives the signal and compares it with a corresponding preset threshold. If the water level is below 20% of the pre-sedimentation tank volume, it is determined that the water level is too low; if the water level is above 80% of the pre-sedimentation tank volume, it is determined that the water level is too high. For both excessively high and low water levels, the central processing unit 15 sends a control signal to the alarm module 18 to trigger an alarm. Simultaneously, the alarm information is displayed on the display screen 17 to promptly remind personnel and prevent water overflow due to excessively high water levels or pump idling due to excessively low water levels. A first turbidity sensor 61 is installed at the outlet of the pre-sedimentation tank to monitor the first turbidity data of the effluent and transmit this data to the central processing unit 15, providing a basis for adjusting subsequent treatment process parameters.

[0036] In a specific implementation, a first flow sensor 71 is installed at the inlet pipe of the solid-liquid separator to monitor the initial flow rate of the wastewater entering the separator. A second turbidity sensor 62 is installed at the outlet of the solid-liquid separator to acquire the second turbidity data of the effluent from the separator; simultaneously, a pressure sensor is installed inside the solid-liquid separator to monitor the internal pressure data. All of the aforementioned initial flow rate data, second turbidity data, and pressure data are transmitted to the central processing unit 15.

[0037] In a specific implementation, the high-density sedimentation tank includes a raw water tank and a sedimentation tank. A level sensor is installed in the raw water tank to monitor the water level; a pH sensor is also installed in the raw water tank to monitor the pH value of the water in real time, facilitating precise addition of coagulants; a stirring speed sensor is installed near the coagulation blades to monitor the operating status of the coagulation motor. A turbidity sensor and a pH sensor are installed inside the flocculation cylinder of the sedimentation tank to monitor the flocculation reaction effect; a suspended solids concentration sensor is installed in the sedimentation inclined plate area to evaluate sedimentation efficiency; a torque sensor is installed near the scraper to monitor the load on the scraper motor; and a pressure sensor and a flow sensor are installed at the sludge inlet of the sludge pump to monitor the sludge discharge status. All the collected data is transmitted to the central processing unit 15 and displayed on the display screen 17.

[0038] In a specific implementation, a sixth turbidity sensor 66 is installed on the pipeline between the high-density sedimentation tank and the intermediate water tank to detect the turbidity data of the effluent from the high-density sedimentation tank and transmit the data to the central processing unit. The central processing unit compares the data with a preset value. If the turbidity data is abnormal, an alarm is immediately triggered and displayed on the screen to promptly remind staff to troubleshoot the abnormality.

[0039] In a specific implementation, a level sensor is installed in the intermediate water tank to monitor the water level and transmit this data to the central processing unit 15, which then controls the effluent from the high-density sedimentation tank and the influent to the mechanical filter. Specifically, a first switching valve 1 is installed on the first pipeline between the high-density sedimentation tank and the intermediate water tank. When the water level in the intermediate water tank is below a set lower limit (e.g., 20% of the tank's volume), the central processing unit 15 assumes insufficient effluent from the high-density sedimentation tank to the intermediate water tank. In this case, it controls the first switching valve 1 to increase its opening or keep it open to ensure sufficient influent to the intermediate water tank. When the water level in the intermediate water tank is above a set upper limit (e.g., 80% of the tank's volume), it reduces the opening of the first switching valve 1 to decrease the effluent flow rate from the high-density sedimentation tank, preventing the intermediate water tank from overflowing.

[0040] In a specific implementation, a first water quality sensor 101 is installed on the inlet pipe of the mechanical filter to detect the first water quality data before entering the mechanical filter, and transmit the first water quality data to the central processing unit 15, and display it on the display screen 17.

[0041] The mechanical filter is equipped with a first pressure sensor 81 and a second pressure sensor 82 at the inlet and outlet, respectively, and transmits all monitored pressure data to the central processing unit 15. The central processing unit 15 determines the filter element blockage by the pressure difference. When the pressure difference between the inlet and outlet is less than the threshold set by the central processing unit 15, the central processing unit 15 determines that the filter element is blocked, controls the alarm module 18 to sound an alarm, and displays the alarm and equipment data on the display screen 17.

[0042] The mechanical filter outlet is also equipped with a third turbidity sensor 63 and a suspended solids concentration sensor, which are used to acquire third turbidity data and suspended solids data, respectively. The acquired data is transmitted to the central processing unit 15. The central processing unit 15 compares the data with the corresponding preset thresholds and transmits the data to the display screen 17 for display. If the threshold is exceeded, the alarm module 18 is controlled to sound an alarm, reminding the staff to check.

[0043] In a specific implementation, a second switching valve 2 is installed on the second pipeline between the mechanical filter and the ultrafiltration device. A liquid level sensor is installed in the ultrafiltration device to detect the liquid level information in the ultrafiltration device and transmit the information to the central processing unit. The central processing unit controls the second switching valve to operate according to the liquid level information in the ultrafiltration device. When the liquid level is too high, the second switching valve is controlled to close to stop water intake. When the liquid level is too low, the second switching valve is controlled to open to start water intake.

[0044] The mechanical filter is equipped with a liquid level sensor to detect the liquid level information in the mechanical filter and transmit the information to the central processing unit. The central processing unit controls the second switching valve to operate based on the liquid level information in the mechanical filter. When the liquid level is too high, the second switching valve is opened to start water intake. When the liquid level is too low, the second switching valve is closed to stop water intake.

[0045] A third pressure sensor 83, a second flow sensor 72, and a fourth pressure sensor 84 and a third flow sensor 73 are installed at the inlet and outlet of the ultrafiltration device, respectively, to monitor the pressure and flow data at the inlet and outlet of the ultrafiltration device during the ultrafiltration process. All acquired data is transmitted to the central processing unit 15. The central processing unit 15 compares the difference between the two values ​​with the corresponding preset threshold. If the value is higher than the threshold, it indicates that the ultrafiltration membrane is damaged; if it is lower than the threshold, it indicates that the ultrafiltration membrane is blocked. The central processing unit outputs control signals to the second and third switching valves to close them. At the same time, the data is transmitted to the display screen 17 for display and the alarm module 18 is activated to alert the staff to check and handle the abnormality.

[0046] A fourth turbidity sensor 64 and an SDI (sludge density index) sensor are installed at the outlet of the ultrafiltration device to acquire turbidity data and sludge density index data of the water effluent from the ultrafiltration device. The acquired data is transmitted to the central processing unit 15. The central processing unit 15 compares the data with the corresponding preset thresholds to evaluate the filtration effect and sludge density of the ultrafiltration membrane. The data is then transmitted to the display screen 17 for display. If the threshold is exceeded, the alarm module 18 is activated to trigger an alarm and remind the staff to check.

[0047] The outlet of the ultrafiltration device is connected to the inlet of the ultrafiltration water tank via a third pipeline. A third switch valve 3 is installed on the third pipeline. A liquid level sensor is installed in the ultrafiltration water tank to monitor the liquid level data in real time and transmit the data to the central processing unit 15. The central processing unit 15 compares the liquid level data with a corresponding preset threshold. When the liquid level data exceeds 80% of the ultrafiltration water tank, the central processing unit 15 controls the third switch valve 3 to close to prevent the ultrafiltration water tank from overflowing; when the liquid level data is lower than 20% of the ultrafiltration water tank, the central processing unit 15 controls the third switch valve 3 to open to prevent the ultrafiltration water tank from running out of water.

[0048] In a specific implementation, the outlet of the ultrafiltration water tank is connected to the inlet of the reverse osmosis unit via a fourth pipeline. The data acquisition module 20 includes a first temperature sensor 12, which is installed on the fourth pipeline between the ultrafiltration water tank and the reverse osmosis unit. The first temperature sensor 12 is installed near the outlet of the ultrafiltration water tank to detect the first temperature data of the outlet of the ultrafiltration water tank and transmits the data to the central processing unit. When the temperature is lower than a preset threshold of the central processing unit, the central processing unit sends a control signal to the alarm device and transmits the data to the display screen for personnel to view, ensuring that the reverse osmosis unit does not ingest low-temperature water for a long time, as low-temperature water will reduce the permeation effect of the reverse osmosis unit.

[0049] A fourth switch valve 4 is also installed on the fourth pipeline. When the liquid level exceeds 80% of the ultrafiltration water tank, the central processing unit 15 controls the third switch valve 3 to close and simultaneously controls the fourth switch valve 4 to open to prevent the ultrafiltration water tank from overflowing. When the liquid level is 20% lower than the ultrafiltration water tank, the central processing unit 15 controls the third switch valve 3 to open and simultaneously controls the fourth switch valve 4 to close to prevent the ultrafiltration water tank from running out of water.

[0050] A fifth turbidity sensor 65 is installed at the outlet of the ultrafiltration water tank to monitor the fifth turbidity data before entering the reverse osmosis device and transmit the water quality data to the central processing unit 15. The central processing unit 15 compares the fifth turbidity data with the corresponding preset threshold. If the threshold is exceeded, the alarm module 18 is activated to remind the staff to check.

[0051] A second water quality sensor 102 is installed at the outlet of the ultrafiltration water tank to monitor the residual chlorine data before it enters the reverse osmosis unit and transmits the residual chlorine data to the central processing unit 15. If the data exceeds the threshold, the alarm module 18 will sound an alarm to remind the staff to check.

[0052] In a specific implementation, pressure sensors and flow sensors are installed at the inlet, concentrate outlet, and product outlet of the reverse osmosis unit, respectively, to acquire corresponding pressure and flow data and transmit them to the central processing unit 15. The central processing unit 15 calculates the permeate rate and the operating pressure difference. If the pressure difference exceeds a preset threshold, an alarm is triggered to notify relevant personnel, thereby monitoring whether the reverse osmosis unit is operating normally. A third water quality sensor 103 is installed at the product outlet to monitor whether the water quality data of the reverse osmosis permeate meets the standards. If it does not meet the standards, an alarm is triggered to remind personnel to check.

[0053] An ORP sensor 14 is installed at the inlet of the reverse osmosis unit to monitor the content of oxidizing substances in the inlet water. If the content of oxidizing substances is higher than the corresponding preset threshold of the central processing unit 15, the fourth switch valve 4 is closed to prevent water with high oxidizing substance content from entering the reverse osmosis unit and protect the reverse osmosis membrane.

[0054] The water outlet of the reverse osmosis device is connected to the water inlet of the clean water tank through the fifth pipeline. A fifth switching valve 5 is installed on the fifth pipeline. A liquid level sensor is installed on the clean water tank to detect the water level in the clean water tank. When the water level is higher than the preset value, the fourth switching valve 4 is closed to stop water inlet, and at the same time, the fifth switching valve 5 is opened for drainage. When the water level is lower than the preset value, the fourth switching valve 4 is opened to start water inlet, and at the same time, the fifth switching valve 5 is closed to stop drainage, realizing automatic water replenishment and drainage control.

[0055] A first water quality sensor 101 is also set at the water outlet of the reverse osmosis device, which is used to detect the conductivity data of the water quality of the water outlet of the reverse osmosis device and transmit the data to the central processor. Once the data is abnormal, an alarm is given and displayed on the display screen.

[0056] In a specific implementation manner, a sixth flow sensor 76 is installed at the water outlet of the clean water tank to monitor the final water outlet flow. If the flow data is abnormal, the central processor 15 controls the alarm module 18 to give an alarm to remind the staff to conduct a check.

[0057] In a specific implementation manner, the data acquisition module 20 transmits the data to the central processor 15 through industrial Ethernet or wireless communication (such as LoRa, 4G / 5G) to ensure real-time and stable data transmission.

[0058] In a specific implementation manner, the data acquisition module communicates with the central processor through the RS485 communication protocol. As Figure 3 shown, the central processor can adopt STM32H743IIT6, which has a 32-bit ARM Cortex-M7 core with a main frequency of 480MHz, has strong data processing capabilities, and can process multiple sensor signals (analog and digital) simultaneously. The working temperature is -40°C to +85°C, and it has strong anti-electromagnetic interference ability, suitable for the complex electromagnetic environment in coal mine shafts. It integrates timers, DMA, etc., and can directly drive actuators such as switching valves and water pumps to realize the interlocking control of equipment such as high-density sedimentation tanks and mechanical filters.

[0059] The turbidity sensor can be a Hach 2100Q turbidity meter, which is widely used in the turbidity monitoring of various water qualities and has the characteristics of high precision and good stability.

[0060] The flow sensor can be an electromagnetic flowmeter, which is suitable for measuring the flow of conductive liquids and is widely used in the monitoring of mine water flow. Its power supply pins are connected to the appropriate DC or AC power supply (such as 24V DC or 220V AC), and the signal output pins are RS485 digital outputs connected to the corresponding input interfaces of the central processor to realize the transmission of flow data.

[0061] The pressure sensor can be a Honeywell ST3000 pressure transmitter.

[0062] Water quality sensors can be used in multi-parameter water quality analyzers, which can simultaneously detect various water quality parameters such as conductivity and pH value.

[0063] The temperature sensor can be a PT100 resistance temperature sensor, which has high accuracy and good stability and is widely used in industrial temperature measurement.

[0064] The SDI sensor can be used with the GE SDI-1 meter to measure the fouling index in water and assess the degree of fouling of the reverse osmosis membrane.

[0065] The ORP sensor can be the Leici E-201-C type oxidation-reduction potential sensor, which can accurately measure the oxidation-reduction potential of water.

[0066] Working principle of this utility model:

[0067] This invention detects whether the ultrafiltration device is malfunctioning by installing pressure sensors at the inlet and outlet of the ultrafiltration device. Once an malfunction is detected, the switch valves at both ends of the ultrafiltration device are closed and an alarm is triggered to remind staff to check and troubleshoot the problem.

[0068] This utility model's data acquisition module integrates a turbidity sensor, flow sensor, pressure sensor, water quality sensor, temperature sensor, SDI sensor, ORP sensor, and liquid level sensor, enabling comprehensive data acquisition from the coal mine underground water treatment device. Simultaneously, it is paired with a switch valve control module to protect the coal mine underground water treatment device. Furthermore, the alarm module and display screen provide a clear view of abnormal equipment information and abnormal data, facilitating troubleshooting by personnel on the surface and accurately locating abnormal equipment. This solves the problem of manually inspecting abnormal equipment one by one in the confined space of an underground mine.

[0069] This invention enables comprehensive monitoring of water quality, equipment status, and operating parameters throughout the entire coal mine underground water treatment process, ensuring stable and reliable water treatment. By combining sensor data with a valve control module, automatic water level adjustment is achieved, reducing manual intervention and improving treatment efficiency. Real-time monitoring of equipment operating status allows for early detection and warning of potential faults, reducing equipment failure rates and maintenance costs. The system automatically records all data during the treatment process, enabling historical data queries and trend analysis, providing data support for process optimization.

[0070] The above technical solutions enable fully automated monitoring of modular coal mine underground water treatment devices, fully leveraging the advantages of modular devices in terms of flexibility, mobility, and detachable assembly, while improving the efficiency and water quality stability of mine water treatment, thus providing a strong guarantee for the efficient utilization of coal mine underground water resources.
