The following is in conjunction with the attached diagram. Figures 1-6 The specific embodiments of this utility model are described in detail below, along with the component numbers marked in the accompanying drawings. In practical applications, this system achieves intelligent control of the circulating water system through signal transmission and collaborative work between multiple modules.

[0023] The water quality analysis module 1 is a crucial component of the system, comprising a turbidity detection unit, a pH detection unit, and a conductivity detection unit. The turbidity detection unit measures the concentration of suspended particulate matter in the circulating water, the pH detection unit measures the acidity or alkalinity, and the conductivity detection unit measures the ion concentration. These detection units are connected to the data processing module 4 via signal lines, transmitting the detected data to the data processing module 4 in real time. The data processing module 4 calculates and optimizes the received water quality parameters and sends the processed results to the control unit 3. The control unit 3 generates control commands based on preset logic, which are transmitted to the flow regulation module 2 via signal lines.

[0024] The flow regulation module 2 consists of a variable frequency pump set and a throttle valve set. The input end of the variable frequency pump set is connected to the control unit 3 via a signal line, and the output end is connected to the actuator 5 via a signal line. The variable frequency pump set regulates the circulating water flow by changing the motor speed, while the throttle valve set further adjusts the flow distribution by changing the valve opening. The input end of the throttle valve set is connected to the variable frequency pump set, and the output end is connected to the circulating water pipeline, thereby achieving precise control of the circulating water flow. The actuator 5 includes an electric actuator rod and a hydraulic drive device. The input end of the electric actuator rod is connected to the flow regulation module 2, and the output end is connected to the hydraulic drive device. The electric actuator rod converts the control signal into mechanical displacement through linear motion, while the hydraulic drive device achieves a wide range of torque output through pressure transmission, thereby driving the mechanical components in the circulating water pipeline to complete the action.

[0025] The environmental monitoring module 6 includes a temperature sensor, a humidity sensor, a wind speed detection unit, and a light intensity detection unit.

The auxiliary control module 7 adjusts the operating mode of the circulating water system according to changes in environmental parameters and transmits the relevant information to a display terminal via signal lines for operators to view.

[0026] The communication module 8 includes a wireless communication unit and a wired communication unit. Its input is connected to the data processing module 4 via a signal line, and its output is connected to the remote monitoring module 9 via a signal line. The wireless communication unit uses 4G / 5G communication technology for long-distance data transmission; the wired communication unit uses industrial Ethernet technology for high-reliability data transmission.

[0027] Alarm module 10 includes an audible and visual alarm and a vibration alarm, which are connected to control unit 3 via signal lines.

The energy consumption monitoring unit monitors the energy consumption of the circulating water system in real time, while the energy-saving optimization unit generates optimization strategies based on the energy consumption data to reduce system energy consumption.

[0028] In actual operation, the water quality analysis module 1 first detects the turbidity, pH value, and conductivity of the circulating water and transmits the results to the data processing module 4. The data processing module 4 calculates and optimizes these data before sending the results to the control unit 3. The control unit 3 generates control commands based on preset logic and transmits the commands to the flow regulation module 2. The flow regulation module 2 regulates the circulating water flow rate through a variable frequency pump set and a throttle valve set, and transmits the control signal to the actuator 5. The actuator 5 drives the mechanical components in the circulating water pipeline to complete the action through an electric push rod and a hydraulic drive device, thereby achieving precise control of the circulating water flow rate.

[0029] Meanwhile, the environmental monitoring module 6 detects the temperature, humidity, wind speed, and light conditions of the external environment of the coal preparation plant and transmits the results to the auxiliary control module 7.

The energy management module 11 monitors and optimizes system energy consumption through the energy consumption monitoring unit and energy-saving optimization unit, ensuring that the system operates efficiently while also achieving energy savings.

[0030] The above modules interact and work collaboratively via signal or data lines, together forming a complete intelligent control system for circulating water in a coal preparation plant. The system's operation demonstrates the close cooperation between the modules, ensuring the smooth implementation of intelligent control of the circulating water system. To better enable those skilled in the art to fully understand and implement this invention, the following supplementary explanation of the specific implementation principle is provided in conjunction with a specific application scenario.

[0031] In the actual operation of a coal preparation plant, the circulating water system needs to cope with fluctuations in water quality, changes in water quantity, and changes in external environmental conditions. The following detailed steps illustrate the implementation process of this utility model and the principles behind its technical effects.

[0032] First, when the water quality analysis module 1 starts working, the turbidity detection unit detects the concentration of suspended particulate matter in the circulating water, the pH detection unit detects the acidity or alkalinity of the circulating water, and the conductivity detection unit detects the ion concentration of the circulating water. These detection units transmit the real-time collected data to the data processing module 4 via signal lines. The data processing module 4 performs calculations and optimizations on the received data, such as normalizing the water quality parameters using a preset algorithm, and generating a comprehensive assessment result of the current water quality status by combining historical data. Subsequently, the data processing module 4 sends the processed result to the control unit 3. The control unit 3 determines whether the current water quality is within a reasonable range based on built-in logic rules and generates corresponding control commands. For example, when an increase in circulating water turbidity is detected, the control unit 3 will generate a command to increase the flow rate for flushing.

[0033] Next, the flow regulation module 2 receives control commands from the control unit 3. The variable frequency pump set adjusts its motor speed according to the commands, thereby changing the total flow rate of the circulating water; the throttle valve group further distributes the flow to each branch by changing the valve opening. For example, under certain operating conditions, when the circulating water system needs to quickly remove suspended particulate matter, the variable frequency pump set increases its motor speed to increase the total flow rate, while the throttle valve group adjusts the valve opening to prioritize delivering more water to critical areas. The flow regulation module 2 transmits the control signal to the actuator 5. The electric actuator converts the electrical signal into mechanical displacement through linear motion, while the hydraulic drive device completes a wide range of torque output through pressure transmission, driving the mechanical components in the circulating water pipeline to complete the action. This series of coordinated operations ensures precise control of the circulating water flow rate.

[0034] Meanwhile, the environmental monitoring module 6 monitors the temperature, humidity, wind speed, and light conditions of the external environment of the coal preparation plant in real time. Temperature and humidity sensors transmit the detected temperature and humidity data to the auxiliary control module 7, while the wind speed and light intensity detection units transmit wind speed and light condition data to the auxiliary control module 7, respectively. The auxiliary control module 7 adjusts the operating mode of the circulating water system based on the received environmental parameters. For example, under high-temperature conditions in summer, the auxiliary control module 7 may trigger an instruction to increase the cooling water flow rate to prevent excessively high circulating water temperature from affecting the washing efficiency. Furthermore, the auxiliary control module 7 also transmits relevant information to a display terminal via signal lines for operators to view and make decisions.

[0035] The communication module 8 plays a crucial role in data transmission throughout the process. The wireless communication unit utilizes 4G / 5G technology to transmit system operating status information over long distances to the remote monitoring module 9; the wired communication unit achieves highly reliable data transmission through industrial Ethernet technology. The remote monitoring module 9 receives and displays the operating status information of the circulating water system in real time, enabling operators to monitor the system's operation at any time. For example, when the remote monitoring module 9 displays an abnormal flow rate in a particular circulating water channel, operators can adjust relevant parameters remotely to quickly resolve the problem.

[0036] When the system detects an abnormal state, the alarm module 10 is triggered. For example, when the pH value of the circulating water exceeds the preset range, the control unit 3 sends a signal to the alarm module 10. The audible and visual alarm alerts the operator through sound and light, while the vibration alarm alerts the operator through physical vibration. This multi-layered alarm mechanism ensures that abnormal states can be detected and handled in a timely manner.

[0037] The energy management module 11 plays a continuous role throughout the entire system operation. The energy consumption monitoring unit monitors the energy consumption of the circulating water system in real time and transmits the data to the energy-saving optimization unit. The energy-saving optimization unit generates optimization strategies based on the energy consumption data, such as reducing the operating frequency of the variable frequency pump unit under low-load conditions or reducing the opening of the throttle valve group during non-critical periods, thereby reducing system energy consumption. In this way, the energy management module 11 not only improves the system's operating efficiency but also achieves energy-saving effects.

[0038] The above steps demonstrate the close cooperation between the modules in this invention. The water quality analysis module 1, flow regulation module 2, control unit 3, data processing module 4, and actuator 5 jointly achieve intelligent control of the circulating water system; the environmental monitoring module 6 and auxiliary control module 7 enhance the system's adaptability to changes in the external environment; the communication module 8 and remote monitoring module 9 enhance the system's maintainability and security; and the alarm module 10 and energy management module 11 provide additional guarantees from the perspectives of safety and economy. Through the above collaborative work, this invention effectively solves the problem of existing circulating water control relying on manual operation or simple automated equipment, achieving efficient and precise control of complex operating conditions, and significantly improving production efficiency and environmental protection.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
