Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment, specifically to an intelligent control system for a vibrating desliming screen. Background Technology

[0002] Applications of vibrating desliming screens: Vibrating desliming screens are devices used in mineral processing, primarily for separating valuable media (such as magnetite powder) from materials. In this process, the media refers to the substances used to aid in mineral separation, such as the heavy media used in heavy media separation processes.

[0003] Adjustment of operating parameters: The operating parameters of a vibrating desliming screen include frequency (vibration speed), amplitude (vibration amplitude), water spray pressure (water spraying force), and water spray volume. These parameters directly affect the desliming effect. Currently, the adjustment of these parameters mainly relies on the operator's experience and intuition, rather than on precise data and scientific calculations. This adjustment method may lead to inconsistencies and instability in the desliming effect.

[0004] Uncertainty in the effectiveness of desliming: Due to the lack of precise control over the adjustment of operating parameters, the desliming effect may fluctuate significantly. This not only affects mineral processing efficiency but may also lead to resource waste and increased costs.

[0005] Deficiencies in the control system: Existing vibrating desliming screen control systems lack real-time monitoring and feedback on the feed rate (the amount of material entering the screen) and the amount of magnetite powder carried away by the material on the screen (the amount of magnetite powder remaining in the material after screening). This lack of real-time monitoring and feedback makes it difficult for operators to adjust operating parameters in a timely manner to adapt to changes in material characteristics, thus failing to maximize desliming efficiency.

[0006] Impact on optimal desliming efficiency: Due to the aforementioned issues, existing vibrating desliming screens struggle to achieve optimal desliming efficiency. Optimal desliming efficiency means minimizing media loss while ensuring mineral recovery, which is crucial for reducing costs and improving the economic efficiency of the concentrator.

[0007] The existing control systems of vibrating desliming screens have the following technical problems: First, the adjustment of operating parameters relies on manual experience. This means that the adjustment of the operating parameters of the vibrating desliming screen (such as frequency, amplitude, water spray pressure, and water spray volume) is not based on precise scientific calculations or data, but rather on the operator's personal experience and intuition. This method of adjustment, which relies on manual experience, may lead to the following problems: different operators may have different adjustment methods, resulting in differences in desliming effect between different shifts or different operators; manual parameter adjustment takes time, and may not be able to respond in time to rapid changes in material characteristics; due to the lack of precise control, the optimal desliming effect may not be achieved, leading to resource waste and low efficiency.

[0008] Secondly, there is a lack of real-time monitoring of key feedback parameters. Due to the lack of real-time data, operators cannot adjust operating parameters in a timely manner according to real-time changes in material characteristics; without real-time feedback, it is difficult to optimize the desliming process to achieve the best desliming effect and efficiency.

[0009] The present invention aims to solve these problems and improve the desizing efficiency and stability of the vibrating desizing screen. Utility Model Content

[0010] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model proposes an intelligent control system for a vibrating desliming screen. By monitoring feedback parameters such as the feed rate of the desliming screen and the amount of magnetite powder carried away by the material on the screen in real time, the system automatically adjusts the operating parameters of the vibrating desliming screen, such as the vibration frequency, amplitude, water spray pressure, and water spray volume.

[0011] The technical solution adopted in this utility model is: an intelligent control system for a vibrating desliming screen, including a control unit, sensors, actuators, a human-machine interface control panel, a vibrating desliming screen, a vibrator, and nozzles;

[0012] The control unit is electrically connected to sensors and actuators. The sensors include a feed rate sensor and a sensor for the amount of magnetite powder carried away by the material on the screen. The actuators include a frequency converter and a hydraulic / pneumatic device. The collected data is transmitted to the control unit, which optimizes and adjusts the operating parameters (vibration frequency, amplitude, water pressure, and water volume of the vibrating screen) according to a preset algorithm. The control unit outputs the adjusted operating parameters (vibration frequency, amplitude, water pressure, and water volume of the vibrating screen), achieving real-time control of the vibrating screen.

[0013] The control unit is controlled via a human-machine interface (HMI) control panel. The HMI is connected to the control unit and can display real-time data, system status, and alarm information. It also allows operators to manually adjust parameters or perform emergency interventions when necessary.

[0014] The vibrator and nozzle are controlled by a frequency converter and a hydraulic / pneumatic device, respectively, and the vibrator and nozzle are mounted on the vibrating desliming screen mechanism.

[0015] Preferably, the human-computer interaction control panel is disposed on the surface of the housing of the control unit device, and the human-computer interaction control panel is provided with several operation buttons.

[0016] Preferably, the feed rate sensor and the magnetite powder carried away by the oversize material are respectively installed at the feed inlet and discharge outlet of the vibrating desliming screen. Sensors (feed rate sensor and magnetite powder carried away by the oversize material sensor) are installed at key locations on the vibrating desliming screen to collect data such as the feed rate and the amount of magnetite powder carried away by the oversize material in real time.

[0017] The beneficial effects of this utility model are:

[0018] (1) A real-time monitoring and feedback mechanism was adopted to realize the intelligent adjustment of the operating parameters of the vibrating desliming screen;

[0019] (2) By optimizing the algorithm, the operating parameters are accurately calculated and adjusted based on real-time data, which improves the desliming efficiency and stability of the vibrating desliming screen.

[0020] (3) It reduces the dependence of the vibrating desliming screen on the operator for adjustment and realizes automated and intelligent production;

[0021] (4) This utility model has broad application prospects and can be applied to different types of vibrating desliming screens, thereby improving the overall level of the mineral processing industry. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-3 As shown, an intelligent control system for a vibrating desliming screen includes a control unit 1, sensors, actuators, a human-machine interface control panel 6, a vibrating desliming screen 7, a vibrator 8, and a nozzle 9.

[0027] The control unit 1 is electrically connected to the sensors and the actuator. The sensors include a feed rate sensor 2 and a magnetite powder amount carried away by the material on the screen 3. The actuator includes a frequency converter 4 and a hydraulic / pneumatic device 5.

[0028] The control unit 1 is controlled by the human-machine interaction control panel 6; the human-machine interaction control panel 6 is set on the surface of the outer shell of the control unit 1, and a number of operation buttons are provided on the human-machine interaction control panel 6.

[0029] The vibrator 8 and the nozzle 9 are controlled by the frequency converter 4 and the hydraulic / pneumatic device 5, respectively, and the vibrator 8 and the nozzle 9 are mounted on the vibrating desliming screen 7 mechanism.

[0030] The feed rate sensor 2 and the magnetite powder carryover sensor 3 are respectively installed at the feed inlet and discharge outlet of the vibrating desliming screen 7.

[0031] This invention features a feed rate sensor at the inlet and a magnetite powder carryover sensor at the outlet. These sensors accurately monitor the feed rate and the amount of magnetite powder carried over by the screen, creating a material parameter monitoring network to capture real-time material dynamics. The collected data is then transmitted to the control unit, which optimizes and adjusts the operating parameters (vibration frequency, amplitude, water pressure, and water volume of the vibrating desliming screen) according to a preset algorithm. Simultaneously, operators can manually adjust the parameters or intervene in emergencies via the human-machine interface control panel when necessary.

[0032] Working principle:

[0033] 1. By using a feed rate sensor and a magnetite powder amount sensor carried away by the material on the screen, the dynamic changes of feed and discharge parameters are captured at a microsecond sampling frequency and transmitted to the control unit.

[0034] 2. After receiving the data, the control unit quickly initiates a multi-parameter collaborative optimization decision-making process based on the pre-loaded intelligent algorithm library. Based on mineralogical characteristic big data and real-time operating condition models, and using preset algorithms, it accurately simulates the desliming effect under different parameter combinations. Through massive computational iterations, it determines the vibration frequency, amplitude, water spray pressure, and water spray volume of the vibrating desliming screen, adaptively adjusting strategies and the optimal parameter set for overall equipment collaborative operation. This ensures that the system accurately adapts to changes in material characteristics at all times, achieving efficient and stable desliming under all operating conditions.

[0035] 3. Upon receiving the command, the frequency converter drives the vibrator to change the vibration frequency and amplitude of the vibrating desliming screen. Based on the preset frequency and amplitude, the parameters of the vibrating desliming screen are precisely controlled and maintained stably. The hydraulic / pneumatic device drives the nozzle to adjust according to the optimal water spray pressure and volume, ensuring that the material is deslimed efficiently under the action of the optimal vibration and water spray parameters. The system continuously optimizes and controls the desliming process based on the feedback of the working conditions, ensuring the stability and efficiency of the desliming process, energy saving and consumption reduction, and constant product quality in all aspects.
