Description

Technical Field

[0001] This utility model relates to the field of ball mill lubrication and vibration monitoring technology, specifically a detection and control system based on ball mill operating conditions. Background Technology

[0002] Ball mills, as important industrial equipment, are widely used in mining, metallurgy, power plants, and other fields for grinding and crushing materials. With the continuous expansion of industrial production scale, the efficient, safe, and stable operation of ball mills has become particularly important. To ensure the long-term stable operation of ball mills, research on ball mill lubrication and vibration monitoring has gradually developed. Currently, the lubrication system of ball mills usually adopts timed oil injection lubrication to ensure that the bearings and gear components of the equipment are well lubricated under high load operation. At the same time, vibration monitoring, as an important means of equipment health management, can monitor the operating status of ball mills in real time and identify abnormal vibration signals. However, due to the harsh operating environment of ball mills, high load, and frequent vibration, traditional lubrication and vibration monitoring methods have many limitations and cannot meet the needs of modern industry for equipment reliability and intelligent management.

[0003] Although existing lubrication and vibration monitoring technologies have achieved certain results in ball mill operation and management, they still have significant shortcomings in terms of practicality and intelligence. Traditional timed oil injection lubrication methods lack the ability to adjust in real time, making it difficult to dynamically adjust the lubrication dosage according to the actual load of the equipment, resulting in problems such as lubricant waste or insufficient lubrication. Under high load conditions, they cannot effectively alleviate friction and wear, affecting the service life of the equipment. Existing vibration monitoring systems usually use a single vibration sensor to monitor the equipment status, without fully considering the reliability improvement that multi-sensor redundancy design may bring. When a sensor fails or a signal error occurs, it is difficult to switch to a backup sensor in time, which may result in the equipment operating status not being monitored in real time. Traditional alarm systems mostly use fixed thresholds to trigger alarms, lacking a multi-level alarm mechanism, making it difficult to provide graded responses according to different levels of anomalies, resulting in some false alarms or alarm lag. Existing systems lack remote monitoring and self-testing functions, and after the equipment fails and stops, they cannot transmit fault information to management personnel in real time, resulting in slow equipment maintenance response speed.

[0032] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] Example 1, referring to Figures 4-8This invention provides a detection and control system based on the working conditions of a ball mill, comprising: a controller including a chip with several output ports and input ports; a flow metering module 100 including a flow meter 101, a first operational amplifier 102, and a second operational amplifier 103, the output of the second operational amplifier 103 being connected to the chip's input port; a drive module 200 including a drive chip 201 and a relay 202, the chip's output port being connected to the input of the drive chip 201; a temperature detection module 300 including a temperature sensor 301 and a third operational amplifier 302, the output of the third operational amplifier 302 being connected to the chip's input port; a vibration detection module 400 including a voltage regulator 401, the vibration detection module 400 being connected to the chip's input port; and a communication module 500 including a display chip 501 and a touch screen 502, the chip's output port being connected to the display chip 501's input port; the functions performed by each series-connected circuit of the drive module 200 include: driving the oil injection motor, heating the oil tank, heating the oil pipe, and alarming for oil pipe blockage, and each circuit of the drive module 200 operates independently.

[0034] Specifically, the controller controls each detection process, including temperature measurement, flow measurement, and vibration data measurement.

[0035] Preferably, in the detection process of the flow metering module 100, the external electrical signal is first collected, and the flow meter 101 converts the external electrical signal into a pulse signal. After the pulse signal is processed by the first operational amplifier 102 and the second operational amplifier 103, it is sent to the chip. After analysis and processing by the chip, when the flow rate is detected to be lower than the set value or the flow rate is 0, the controller sends a signal to the circuit corresponding to the drive module 200 to realize the function of oil pipe blockage alarm and shut down the system.

[0036] Furthermore, in the temperature detection circuit 300, the temperature sensor 301 is a PT100. The temperature signal measured by the temperature detection circuit 300 is transmitted to the controller. When the temperature in the oil pipe or oil tank is lower than the set value, the chip sends a command to the drive circuit 200 to drive the oil pipe or oil tank to heat up.

[0037] Specifically, the vibration monitoring module 400 is used to detect the vibration of the gears inside the ball mill, monitor the movement of the gears in real time, and prevent excessive vibration from accelerating gear wear or even causing gear cracks.

[0038] Example 2, refer to Figures 1-8 As one embodiment of this utility model, a detection and control system based on ball mill operating conditions is provided, comprising:

[0039] S1: Use a touchscreen and controller for data acquisition and real-time monitoring.

[0040] Furthermore, data acquisition includes communication between the touchscreen and the controller via a 485 communication circuit, real-time display of tank temperature, fuel line temperature, fuel injection quantity per injection, and vibration monitoring data; and setting fuel line heating limits, tank temperature limits, single injection time, interval time, vibration alarm limits, and fuel line blockage limits via the touchscreen.

[0041] It should be noted that real-time monitoring includes the controller automatically detecting and collecting data in real time based on the parameters set on the touch screen, while monitoring parameter changes and issuing an early warning signal when the parameters exceed the set limits.

[0042] It should also be noted that the touchscreen and controller communicate via a 485 communication circuit, displaying key parameters such as oil tank temperature, oil pipe temperature, fuel injection quantity, and vibration data in real time. Relevant limit parameters (such as oil pipe heating limits and vibration alarm limits) can be set via the touchscreen. The controller automatically collects and monitors data based on these settings, issuing a warning signal when parameters exceed the set limits. The main function of this step is to establish an interactive data monitoring platform, enabling operators to understand the equipment status in real time and adjust parameters promptly to ensure the equipment operates in optimal condition. By achieving real-time data acquisition and monitoring, the controllability and stability of the equipment are enhanced, reducing the risk of equipment failure due to abnormal parameters, and laying the foundation for intelligent management of lubrication and vibration control.

[0043] S2: Uses the controller for lubrication and temperature control, and completes the operation of the fuel injection motor drive and temperature regulation.

[0044] Furthermore, the lubrication system includes a controller based on the CPU ADUCM361BCPZ128-R chip, which controls the flow meter and the oil injection motor to work together. The flow meter monitors the oil injection volume by outputting pulse signals. When the flow rate is lower than the set value or is 0, a blockage alarm is triggered. At the same time, the system performs zoned heating control on the oil tank and oil pipes based on the feedback data from the temperature sensor, so that the lubricating oil is sprayed within the set temperature range.

[0045] It should be noted that temperature control includes the controller dynamically adjusting the temperature of the oil tank and oil pipes to adapt to different ambient temperatures. The controller automatically adjusts the heating power based on data from external temperature sensors. In low-temperature environments, the oil tank is heated first to regulate the fluidity of the lubricating oil. In high-temperature environments, the oil injection frequency is reduced.

[0046] It should also be noted that the reference Figure 2This document describes the complete automatic control process of oil injection in a ball mill lubrication system, detailing the specific operations and judgment conditions for each step. The process begins with "Startup," indicating that the lubrication control program is activated and ready to execute the automatic oil injection process. After startup, the system first enters the "Oil Pipe Heating" step, heating the oil pipes to ensure good fluidity of the lubricating oil. This step is particularly important in low-temperature environments, preventing the lubricating oil from thickening due to low temperature, which would affect the injection effect. Once the oil pipes reach the set temperature, the system enters the "Injection" step, starting the injection motor to spray lubricating oil onto key components of the ball mill, such as bearings and gears, to reduce... To minimize friction and wear and ensure normal equipment operation, the system performs real-time "oil pipe blockage detection" during oil injection. This involves monitoring the flow rate within the oil pipes. If the flow meter detects a flow rate below a preset limit or zero, the system is considered blocked. In this case, the system immediately triggers a "stop" operation, halting the ball mill to prevent severe wear or damage due to insufficient lubrication. If no blockage occurs, the system enters the "interval timing" phase. In this phase, a set oil injection interval is established to ensure the next injection operation is performed within the appropriate time interval, thus achieving stable lubrication. Figure 3 This paper describes the automatic control process of oil tank heating in a ball mill lubrication system, aiming to ensure that the lubricating oil temperature is maintained within a suitable range to guarantee lubrication effect. The process begins with "start," indicating that the heating control system has been activated. Then, the system enters a judgment step. If the oil tank temperature is lower than the set value of -10℃ (i.e., lower than the predetermined lower limit), the "oil tank heating" operation is initiated to heat the lubricating oil in the tank, preventing the oil temperature from being too low and affecting its fluidity and lubrication effect. During the heating process, the system continuously monitors the oil tank temperature. When the temperature reaches the set value, the system stops heating and enters the "stop heating" step to ensure that the lubricating oil temperature is maintained within a suitable range for injection, thereby avoiding oil deterioration caused by excessive temperature. The entire process achieves intelligent adjustment of lubricating oil temperature through a closed-loop design of temperature detection and heating control to adapt to temperature requirements in different environments, ensuring the stability and efficiency of the lubrication system.

[0047] It should also be noted that the controller uses the ADUCM361BCPZ128-R chip for flow monitoring and oil injection motor drive operation. The flow meter monitors the oil injection volume through pulse signals. When the flow rate is lower than the set value or zero, a blockage alarm is triggered to prevent equipment wear caused by insufficient lubrication. In addition, the controller performs zoned heating control of the oil tank and oil pipes based on temperature sensor feedback data to ensure that the lubricating oil is injected within the appropriate temperature range, avoiding excessively high or low oil temperatures that could affect lubrication. Through dynamic temperature adjustment, the controller can adaptively adjust the heating power according to changes in ambient temperature. In low-temperature environments, the oil tank is heated first to ensure oil fluidity, while in high-temperature environments, the oil injection frequency is reduced to save resources. This step, through intelligent lubrication and temperature management, achieves optimized control of lubricating oil dosage and temperature, extends the service life of the equipment, and improves the system's energy efficiency.

[0048] S3: Anomaly detection and alarm based on vibration and flow parameters, triggering alarms and performing shutdown protection.

[0049] Furthermore, the anomaly detection and alarm system includes multi-level alarms based on the acceleration signals fed back by the vibration sensor. The vibration monitoring is set to three alarm levels: low, medium, and high. When a low-level alarm is triggered, only the data is recorded. When a medium-level alarm is triggered, the operator is alerted. When a high-level alarm is triggered, the system automatically shuts down and the cause of the fault is recorded.

[0050] It should be noted that the anomaly detection and alarm also includes the controller having a multi-sensor redundancy design, with vibration and flow sensors installed in different locations. When the data of a certain sensor is abnormal, the controller switches to the backup sensor to continue monitoring and sends real-time alarm information to the monitoring center via remote alarm. If the system still cannot recover automatically after three alarms, the system reminds on-site personnel to intervene manually.

[0051] It should also be noted that the reference Figure 4This paper demonstrates a circuit design for monitoring the flow rate of lubricating oil in a ball mill lubrication system, ensuring that the lubricating oil is sprayed in a predetermined amount. The core components of the circuit include a signal detection unit, a signal amplification unit, and an output signal conversion unit. First, the flow sensor generates a weak pulse signal, which is initially amplified by a first-stage amplifier circuit (LM324A operational amplifier) ​​to increase the signal strength so that it can be processed by subsequent circuits. Then, the initially amplified signal is passed through a filter capacitor and resistor network to a second-stage operational amplifier (LM324B) for further amplification to ensure that the signal is stable and strong enough. Finally, the pulse signal after secondary amplification is output to the P0.4 pin of the controller as the input signal for lubrication system flow monitoring. When the flow rate is lower than the preset value or the signal is 0, the controller will identify it as a blockage or abnormality, thereby triggering an alarm or shutdown protection. This circuit design, through multi-stage amplification and signal conversion, ensures the accuracy and sensitivity of flow monitoring, providing real-time and reliable flow data for the ball mill lubrication system.

[0052] It should also be noted that anomaly detection and alarm involve the cooperation of various drive circuits, as referenced. Figures 5-8 The drive circuit includes an injection motor drive circuit, a fuel tank heating drive circuit, a fuel line drive circuit, and a blockage alarm drive circuit. (See reference...) Figures 6-7 Temperature measurement circuit and vibration detection circuit in a multi-sensor redundancy design. Figure 8 The circuit for the communication module 500 uses the SP3485 chip as its core component to implement RS-485 communication functionality, connecting the CPU and the ET2100 touchscreen. The CPU's P0.0, P0.1, and P0.2 ports are connected to the SP3485 chip's DI (data input), DE (transmit enable), and RE# (receive enable) pins, respectively, controlling data transmission and reception. The SP3485 chip's A and B pins are connected to the ET2100 touchscreen to achieve differential signal transmission, enhancing the anti-interference capability and stability of data communication. The circuit feeds back the data sent by the touchscreen to the CPU via the RO (receive output) pin, ensuring bidirectional data transmission. This design enables the touchscreen to display real-time monitoring data such as temperature, flow rate, and vibration of the lubrication system, while also allowing operators to set parameters via the touchscreen. The entire RS-485 communication circuit, through differential transmission and chip control, achieves stable, reliable, and real-time data interaction between the CPU and the touchscreen, providing the system with accurate data acquisition and monitoring capabilities.

[0053] It should also be noted that the controller sets three alarm levels—low, medium, and high—based on the acceleration signals from the vibration sensors. Low-level alarms record data, medium-level alarms alert operators, and high-level alarms trigger automatic shutdown and record the cause of the fault. This multi-level alarm mechanism can flexibly handle faults according to their severity, avoiding false alarms or delayed responses that might occur with a single alarm threshold. Furthermore, the system features a multi-sensor redundancy design, installing multiple vibration and flow sensors in critical parts of the equipment. When one sensor fails, the system automatically switches to a backup sensor, ensuring continuous monitoring. The remote alarm function can send equipment fault information to the monitoring center in real time, alerting on-site personnel for manual intervention if the equipment fails to recover automatically after multiple alarms. This intelligent anomaly detection and alarm mechanism ensures the safety and stability of the equipment under fault conditions, significantly reducing downtime and maintenance costs while improving the reliability of equipment operation.

[0054] Example 3 is an embodiment of this utility model, which provides a detection and control system based on the working conditions of a ball mill. In order to verify the beneficial effects of this utility model, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0055] First, the experimental setup includes a ball mill lubrication system with a touchscreen (model ET2100) and a controller, connected via a 485 communication circuit. The entire system is equipped with components such as flow sensors, vibration sensors, and temperature sensors to ensure real-time data acquisition and feedback. The experimental environment is controlled at 20°C room temperature, simulating three external temperature environments: low temperature (5°C), normal temperature (20°C), and high temperature (35°C). An adjustable flow control valve is added to the lubricating oil pipeline to simulate oil pipe blockage. After the experiment begins, the operator sets the oil pipe heating limit to 10°C, the oil tank heating limit to 30°C, the single oil injection time to 3 seconds, the oil injection interval to 5 minutes, the vibration alarm limit to 0.8g, and the oil pipe blockage limit to 30% via the touchscreen. During operation, the controller collects real-time data on oil tank temperature, oil pipe temperature, oil injection volume, and vibration monitoring via 485 communication and feeds this data back to the touchscreen for monitoring. The system monitors these preset parameters in real time; when any parameter exceeds the set value, the controller immediately issues a warning signal to notify the operator for timely handling. The controller is CPU-based. The ADUCM361BCPZ128-R chip, linked to the flow meter and oil injection motor drive system, ensures that lubricating oil is injected at the set flow rate. When the ambient temperature is 5℃, the system initiates an oil pipe heating program to ensure the oil temperature reaches above 10℃. If the ambient temperature is above 30℃, the system reduces the injection frequency to save lubricating oil. Simultaneously, during the injection process, the controller monitors the flow rate in the oil pipe through the flow meter. When the flow rate is below 30% or zero, the system determines that the oil pipe is blocked and triggers a blockage alarm signal. During equipment operation, the controller uses vibration sensor feedback to adjust the pressure... The speed signal monitors vibration and processes it according to three alarm levels: low, medium, and high. When the vibration data is below 0.4g, only the data is recorded. When the vibration is between 0.4g and 0.8g, the operator is alerted. When the vibration exceeds 0.8g, the system triggers a high-level alarm and immediately shuts down. In addition, the control system is equipped with a multi-sensor redundancy design. When a sensor fails, it automatically switches to a backup sensor and sends real-time alarm information to the monitoring center through a remote alarm module, ensuring the continuity and safety of the system under abnormal conditions.

[0056] The oil temperature control demonstrates the system's adaptability under different temperature conditions. Especially under low-temperature conditions, the oil temperature can be stabilized above the set heating limit, ensuring the fluidity of the lubricating oil and avoiding problems such as insufficient oil injection or poor lubrication caused by low temperatures. Secondly, in terms of flow control, the system can monitor and report flow abnormalities in real time through the linkage of the flow meter and controller, triggering blockage alarms in a timely manner and effectively preventing equipment wear caused by oil pipe blockage. In addition, the multi-level vibration alarm mechanism allows the system to flexibly handle vibration according to the intensity of vibration. Minor vibrations are recorded and archived, stronger vibrations prompt operators to pay attention, and severe vibrations directly shut down for protection, avoiding the risks of false alarms or delayed alarms caused by single alarms.

[0057] Example 4, refer to Figure 9 This invention provides a detection and control system based on the working conditions of a ball mill, comprising a display control module, a lubrication temperature control module, and a detection and alarm module.

[0058] The display control module is used to collect data and monitor it in real time using a touch screen and controller; the lubrication and temperature control module is used to control lubrication and temperature using the controller, and to complete the operation of the oil injection motor drive and temperature adjustment; the detection and alarm module is used to detect and alarm abnormalities based on vibration and flow parameters, trigger alarms and perform shutdown protection.
