Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0038] The inventor of the present invention has found that in the production process of mining, building materials, electric power, chemical industry and other industries, ball mills are widely used for grinding various materials such as coal and ore. A certain number of steel balls are installed inside the ball mill 4, and the impact and grinding effect of the steel balls are used to crush large pieces of materials to the required fineness. With the long-term operation of the ball mill 4, the steel balls will be reduced in size due to wear, affecting the grinding efficiency and product quality. Therefore, it is an indispensable link in the production process to regularly replace and screen the steel balls in the ball mill 4 to ensure the normal operation and production efficiency of the equipment. The traditional screening method relies on manual operation, which is cumbersome to operate and prone to errors, affecting the screening effect. Based on this, in the embodiment of the present invention provided by the inventor, the sifter 13 in the screening device is equipped with round holes of uniform size, which can effectively screen out steel balls of qualified size. At the same time, the feeding device 2, the screening device 1 and the discharging device 3 work together to reduce the labor intensity of the operator and the error of manual operation, improve work efficiency, and ensure the accuracy and efficiency of steel ball screening.

[0041] In the embodiment of the present application, the feeding device 2, the screening device 1 and the discharging device 3 work together to realize the automatic screening of steel balls, reduce the labor intensity of the operators, reduce the labor intensity of the operators and the errors of manual operation, improve work efficiency, and ensure the accuracy and efficiency of steel ball screening. At the same time, through the circular holes set on the outer shell of the sifter 13 in the screening device 1, steel balls of qualified size can be effectively screened out. Optionally, circular holes of uniform size can be set on the outer shell. Since the horizontal heights of the feed port 13-1 and the discharging port 13-2 are different, qualified steel balls can slide to the discharging port 13-2, then enter the discharging device 3, and then be re-transported into the ball mill 4 to ensure its normal operation.

[0042] In addition, in a possible implementation, in order for the steel balls to smoothly reach the screening device 1, a first guide groove 11 is provided between the feeding device 2 and the screening device 1. In order to mitigate the impact of the steel balls on the screener 13, a first buffer bin 12 is provided between the first guide groove 11 and the screener 13.

[0043] As a feasible implementation, the sifter 13 of the screening device in the embodiment of the present application includes a main shaft, and the screening device also includes a supporting component and a driving component; the main shaft 13-5 runs through the center of the sifter 13, and both ends of the main shaft 13-5 are fixedly connected to the housing; the supporting component is connected to both ends of the main shaft 13-5, and is used to support the sifter 13; the driving component is used to drive the main shaft 13-5 to rotate. In a possible implementation, the driving component includes a motor 16 and a reducer 15, the motor 16 is connected to the reducer 15 through a coupling, and the reducer 15 is connected to the main shaft 13-5.

[0044] In the embodiment of the present application, in order to ensure the stability of the screener 13, support frames 14 are provided at both ends of the screener 13, and the support frames 14 are connected to the main shaft 13-5 of the screener 13. In order to ensure the rotation of the screener 13, a main shaft 13-5 is provided on the axis of the screener 13, and both ends of the main shaft 13-5 are fixedly connected to the shell. In a possible implementation, wheels are connected to both ends of the main shaft 13-5, and the wheel includes a spoke 13-4 and a hub 13-3, and the hub 13-3 is connected to the main shaft 13-5, and one end of the spoke 13-4 is connected to the hub 13-3, and the other end is connected to the shell of the screener 13. In order to achieve smooth rotation of the screener 13 and ensure screening efficiency, a reducer 15 and a screener 13 are arranged at the position where the feed port of the screener 13 is connected to the main shaft 13-5. The high speed of the motor 16 is transmitted to the reducer 15 through the coupling. The reducer 15 converts the high speed into a low-speed and high-torque output, driving the main shaft 13-5 to drive the screener 13 to rotate; through the above connection, the motor 16 and the reducer 15 can efficiently drive the screener 13 to achieve stable and smooth rotation, thereby ensuring the screening efficiency and accuracy of the steel balls.

[0045] In a possible embodiment, the screener 13 includes at least one cylindrical lining plate, at least one cylindrical lining plate is used to be attached to the outer shell, a circular hole is arranged on the cylindrical lining plate, and the center of the circular hole of the cylindrical lining plate is aligned with the center of the circular hole of the outer shell, and the cylindrical lining plate is removable.

[0046] In the embodiment of the present application, in order to enable the sifter 13 to screen steel balls of different sizes, a detachable cylindrical liner is provided on the sifter 13, and circular holes of uniform size are also provided on the liner. In actual use, if the diameter of the circular hole of the outer shell of the sifter 13 meets the screening requirements, the cylindrical liner may not be provided. If the diameter of the circular hole of the outer shell of the sifter 13 does not meet the screening requirements, the steel balls can be screened by providing a cylindrical liner. When in use, the center of the circular hole of the cylindrical liner needs to be aligned with the center of the outer shell so that qualified steel balls can fall smoothly.

[0047] In a possible implementation, a lifting device is provided at the discharge port 13-2, and the height of the discharge port 13-2 is adjusted by the lifting device, so that the inclination angle of the screener 13 can be adjusted to optimize the screening process, making the device more adaptable to steel balls of different sizes and weights, thereby improving the screening efficiency and accuracy.

[0048] In an embodiment of the present application, the lifting device may be, for example, a spiral lifting device, which is mounted on a support component on one side of the discharge port 13-2 of the screener 13, and the support component is provided with fixing holes and guide rails to facilitate the stability of the spiral lifting device and adjust the height. The spiral lifting device includes: a screw, a nut, a lifting seat and a driving device; the screw and the nut cooperate, and the screw drives the nut to slide up and down to complete the height adjustment of the support point. A lifting seat is provided at the top of the screw, and the lifting seat is connected to the supporting component to ensure that it can stably bear the weight of the screener 13 during the lifting process. The driving method adopts two methods, for example, manual and electric. The manual method controls the rotation of the screw by a handle or a knob; the electric method drives the screw to rotate by a motor 16, which is more convenient to use and can achieve precise control.

[0049] As a feasible implementation mode, the feeding device 2 of the screening device in the embodiment of the present application includes: a first hopper 22 and a first conveyor 24; the inlet of the first hopper 22 is used to be connected to the ball mill 4, the outlet of the first hopper 22 is connected to the inlet of the first conveyor 24, and the outlet of the first conveyor 24 is connected to the screening device.

[0050] In the embodiment of the present application, the ball mill 4 is connected to the first hopper 22 through a metal chute 21 to avoid the impact caused by the direct fall of the steel balls and the wear of the first hopper 22. The presence of the metal chute 21 also effectively reduces the risk of blockage. In a possible implementation, a second buffer bin is provided between the first hopper 22 and the first conveyor 24 to protect the first conveyor 24 and prevent the steel balls from flowing in too quickly to cause accumulation and overload. In a possible implementation, a first gate 22-1 is provided below the first hopper 22. The first gate 22-1 flexibly adjusts the falling speed and quantity of the steel balls in the first hopper 22 according to the processing capacity of the first conveyor 24 and the screening device 1, so as to avoid a large number of steel balls entering instantly, causing blockage of the first conveyor 24 or overloading of the screening device 1. In one possible embodiment, a vibrating feeder can be installed below the first hopper 22 to ensure that the steel balls are evenly distributed when flowing from the first hopper 22 into the vibrating feeder 22-2 to avoid excessive or insufficient input of steel balls. The discharge port 13-2 of the vibrating feeder 22-2 is connected to the entrance of the second buffer bin 23 to ensure that the steel balls smoothly enter the second buffer bin 23.

[0051] As a feasible implementation, the sensor device in the embodiment of the present application includes a first weighing sensor 50-1 and a flow sensor 50-2; the first weighing sensor 50-1 is fixedly installed at the end of the first hopper 22 to monitor the weight of the steel ball; the flow sensor 50-2 is fixedly installed at the end of the first conveyor 24 to monitor the flow rate of the steel ball through the first conveyor 24. The data acquisition device is connected to the sensor device to collect and process the data transmitted by the sensor device and transmit it to the control system; the control system processes the data and outputs the results for the staff to monitor the operating status of the screening device for timely adjustment.

[0052] In the embodiment of the present application, the first weighing sensor 50-1 is installed below the first hopper 22 to monitor the weight of the steel balls, which helps to prevent the entire screening device 1 from being overloaded. The flow sensor 50-2 is installed at the discharge port 13-2 of the first conveyor 24 to monitor the flow rate of the steel balls through the first conveyor 24, which helps to ensure that the steel balls are smoothly transmitted to the screener 13. The sensor device also includes a rotation speed sensor 50-3, which is installed on the shaft portion where the main shaft 13-5 is connected to the screener 13. By monitoring the rotation speed of the main shaft 13-5, the operating state of the screener 13 is monitored in real time to ensure that the screener 13 is screened at the optimal rotation speed to avoid the speed being too high or too low to affect the screening accuracy. The data acquisition device is connected to the sensor device and transmits the collected data to the control system. The control system processes the data and outputs the results for the staff to monitor the operating state of the screening device for timely adjustment.

[0053] The first weighing sensor 50 - 1 is, for example, a strain gauge weighing sensor, the flow sensor 50 - 2 is, for example, a turbine flow sensor 50 - 2 or a mass flow sensor, and the rotation speed sensor 50 - 3 is, for example, a photoelectric encoder or a Hall effect sensor.

[0054] It should be noted that the data acquisition device is the core of the entire screening device, which is responsible for collecting and processing data from various sensors. The data acquisition device can adopt, for example, a PLC system, and the specific model adopts, for example, the Siemens S7-1200 series or the Omron CP1H series. The PLC system has sufficient input and output (I / O) points, and can support the coordinated work of various sensors and equipment of the screening device. The data specifically collected by the PLC system includes: through the first weighing sensor 50-1, the PLC system monitors the weight of the steel balls in the first hopper 22 in real time, monitors the weight of the steel balls, so as to evaluate the total amount of steel balls in real time. Through the flow sensor, the PLC system can monitor the flow rate of the steel balls through the conveyor, can determine whether the steel balls flow smoothly, and adjust the speed of the conveyor as needed. Through the rotation speed sensor 50-3, the PLC system can monitor the rotation speed of the main shaft 13-5, and this data reflects the working state of the screener 13, ensuring that the screener 13 is screened at the optimal rotation speed, and avoiding the influence of the screening accuracy on the rotation speed being too high or too low.

[0055] In addition, after the data acquisition device, i.e., the PLC system, collects the implementation data in the screening device 1, it transmits it to the control system, which analyzes the transmitted data in real time and feeds back the analysis results to the staff, who take measures on the screening device according to the analysis results. For example:

[0056] First, the control system will determine whether the input amount of steel balls needs to be adjusted based on the real-time steel ball weight data. If the weight increases too quickly, the system will feedback the adjustment notification to the staff, and the staff can reduce the entry speed of the steel balls by adjusting the feeding device 2 to prevent overload operation.

[0057] Second, the control system can monitor the flow rate of the steel balls through the flow sensor 50-2. If the flow rate of the steel balls is found to be too fast or too slow, the control system will adjust the notification and feedback to the staff. The staff will adjust the speed of the first conveyor 24 to ensure that the steel balls are stably transported to the screener 13.

[0058] Third, the control system can monitor the actual rotation speed of the screener 13 through the rotation speed sensor 50-3. If the rotation speed is found to deviate from the optimal range, the control system will notify the staff, and the staff will adjust the output power of the motor 16 and adjust the rotation speed of the screener 13 to ensure the efficiency and accuracy of the screening process.

[0059] In addition, the control system can also detect the vibration frequency and amplitude of the vibrating feeder 22 - 2 , and provide timely feedback to the staff for adjustment to ensure that the steel balls can be evenly distributed into the screener 13 .

[0060] During the operation of the entire screening device, the data acquisition equipment and control system continuously collect and feedback data, and continuously inform the staff to adjust the working status based on the data of the equipment operation. Each adjustment will generate new data, and the system will continue to optimize the operating parameters of the equipment based on this feedback information. This closed-loop control process ensures that the screening device always operates in the best condition, avoiding efficiency losses caused by unstable operation or improper equipment settings.

[0061] In a possible implementation, the discharging device 3 includes: a second hopper and a second conveyor 33 ; the second hopper 32 is connected to the discharging port 13 - 2 , and the second hopper 32 is connected to the second conveyor 33 .

[0062] In the embodiment of the present application, the second hopper 32 is connected to the discharge port 13-2 through the second guide groove 31. A second weighing sensor 50-4 is installed at the end of the second hopper 32 to monitor the weight of the steel balls, which helps to prevent the entire discharge device 3 from being overloaded. A second gate 32-1 is set at the end of the second hopper 32. The second gate 32-1 flexibly adjusts the falling speed and number of steel balls in the second hopper 32 according to the processing capacity of the second conveyor 33 to avoid a large number of steel balls entering instantly and causing the second conveyor to be blocked. In a possible embodiment, the discharge device 3 also includes a collecting device 34, which is arranged directly below the sifter 13 and is used to collect materials with a diameter smaller than the diameter of the circular hole of the outer shell of the sifter 13.

[0063] Working principle: When it is found that the steel balls in the ball mill 4 are worn too much, affecting the grinding efficiency and product quality, the ball mill 4 equipment is suspended, and the steel balls are guided from the ball mill 4 to the metal chute 21 by gravity. The first hopper 22 is used as the starting point of the feeding device to ensure that the steel balls enter the screening device 1 in a slow and controllable manner. The outlet of the first hopper 22 is provided with a gate and a vibrating feeder 22-2 to control the flow rate and quantity of the steel balls to avoid blockage or overload. After opening the gate of the first hopper 22, the steel balls enter the first conveyor 24, and the first conveyor 24 is responsible for transporting the steel balls to the first guide trough 11 of the screening equipment 1. By setting the first buffer bin 12, the steel balls in the first guide trough 11 smoothly enter the hollow cylindrical screener 13 from the first buffer bin 12. The steel balls smaller than the diameter of the circular hole of the outer shell of the screener 13 are screened out and enter the collecting device 34 during the rotation of the reducer of the screener 13. The qualified steel balls larger than the diameter of the circular hole of the outer shell of the screener 13 slide to the discharge port 13-2, and then enter the second hopper 32 and the second conveyor 33, and then are transported back into the ball mill 4 to ensure its normal operation.

[0064] At the same time, during the operation, the data acquisition equipment and control system continuously collect and feedback data, and continuously inform the staff to adjust the working status based on the data of the equipment operation. Each adjustment will generate new data, and the system will continue to optimize the operating parameters of the equipment based on this feedback information. This closed-loop control process ensures that the screening device always operates in the best condition, avoiding efficiency losses caused by unstable operation or improper equipment settings.
