Description

Technical Field

[0001] The utility model relates to the technical field of coal slime separation, in particular to a control system for a coal slime separation device. Background Art

[0002] The basic principle of the coal slime separator is as follows: In the control system of the coal slime separator, generally only a density PID control loop is set. When the bucket is full of water, the water pressure sensor is set to a density of 1g / cm 3 The coal slime particles in the slurry settle in the barrel. The pressure measured by the pressure sensor is proportional to the slurry density. It is converted into relative density through the PLC program, and then the valve opening degree is determined by comparing the set density value with the relative density value.

[0003] In the above-mentioned prior art, large particles inevitably enter the feed, which may cause the valve to often fail to open or be out of control. Personnel are unable to inspect the equipment accessories all the time. If the problem is not discovered in time, it will affect the ash content of the product. People are often required to check and clear the blockage, which increases the workload of the operators and creates unsafe factors. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing technology and propose a coal slime sorting device control system, which can automatically identify the blockage of the discharge valve and automatically solve the blocking particles. Through wireless remote control technology, operators and managers can conveniently view the equipment operation status from their mobile phones, thereby reducing the workload of operators.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A control system for a coal slime separation device includes an expert control system, a pressure sensor, and a discharge valve, wherein the pressure sensor is located on the left side of the discharge valve and the expert control system is located on the top of the discharge valve;

[0007] The expert control system is equipped with a programmable controller, a display screen and a remote data transmission module.

[0008] As a further solution of the present invention: the discharge valve is a pipe clamp valve.

[0009] As a further solution of the present invention: the discharge valve includes an analog signal input device and an analog signal output device, a fault alarm device, and a switch limit device.

[0010] As a further solution of the present invention: the discharge valve also includes a lined wear-resistant hose and an aluminum alloy shell, and both ends of the wear-resistant hose are completely sealed with the aluminum alloy shell; the discharge valve also includes a potentiometer and a gear.

[0011] As a further solution of the present invention: the pressure sensor is programmed by the programmable controller to calculate the relative density and then the value is displayed on the display screen.

[0012] As a further solution of the present invention: the programmable controller is connected to the discharge valve via a wire, the programmable controller is connected to the display screen via a communication cable, and the programmable controller is connected to the remote data transmission module via a network cable.

[0013] As a further solution of the present invention: the remote data transmission module remotely transmits the data of the programmable controller to the terminal through network technology.

[0014] The beneficial effects of the utility model are:

[0015] 1. Automated Control and Fault Identification: Through a programmable logic controller (PLC) and PID control loop, the system automatically identifies and reports discharge valve faults. When the actual valve opening differs significantly from the set value, the system automatically identifies the fault and corrects it by increasing the valve opening, ensuring continuous and stable system operation.

[0016] 2. Real-time monitoring and remote adjustment: Equipped with a remote data transmission module (supporting 5G or Ethernet), system data can be transmitted to the terminal device in real time, enabling remote monitoring and adjustment functions via mobile phone APP or client. Users can monitor the operating status of the coal slime separation device anytime and anywhere and make timely adjustments.

[0017] 3. High precision and high stability: The relative density of the coal slime is accurately calculated through the pressure sensor and linked with the opening of the discharge valve to ensure that the working density of the coal slime sorting device is consistent with the preset value, thereby improving the working accuracy and stability of the system.

[0018] 4. Fault alarm and historical data recording: The system has a fault alarm function. When an abnormality occurs, it can issue an alarm in time. It can also help operators analyze the cause of the fault and improve the maintenance efficiency of the equipment through historical data recording and automatic generation of curve graphs.

[0019] 5. Optimized valve adjustment control: The discharge valve is equipped with an adjustable potentiometer and gear to achieve precise control of the valve opening, optimizing the efficiency and accuracy of the coal slime sorting process.

[0020] The utility model provides a control system for a coal slime sorting device with functions of automatic identification and feedback of discharging faults, automatic elimination of discharging faults, wireless remote monitoring, and automatic generation of curves based on historical data. The control system for the coal slime sorting device can solve the problem of difficulty in personnel inspections when a discharging valve fails, and can realize remote monitoring of the equipment operation status via a mobile phone APP through a remote module, thereby ensuring the normal and efficient operation of the equipment and providing data support for adjustment of background parameters of the equipment.

[0030] As a preferred embodiment of the present invention, the pressure sensor 2 is programmed by the programmable controller to calculate the relative density and then the value is displayed on the display screen.

[0031] As a preferred embodiment of the present utility model, the programmable controller is connected to the discharge valve 3 through a wire, the programmable controller is connected to the display screen through a communication cable, and the programmable controller is connected to the remote data transmission module through a network cable. The programmable controller realizes the switching quantity and analog quantity of the discharge valve 3 through programming, reads the given value and feedback value of the discharge valve 3, realizes automatic identification and feedback of the discharge fault and automatic elimination of the discharge fault, and the automatic identification and feedback of the discharge fault is to use the PID loop instruction proportional, integral, and differential loop of the programmable controller to compare the given value displayed after the discharge valve 3 is opened or closed with the feedback value to take the difference. When the difference is too large, the fault of the discharge valve 3 is automatically identified; the given value displayed after the discharge valve 3 is opened or closed is compared with the feedback value to take the difference.

[0034] Linked control of operating density and discharge valve: The control system of the coal slime separator operates based on a given operating density. First, a target operating density is set. When the actual operating density exceeds the given density, the discharge valve automatically opens. At this point, the opening of discharge valve 3 is set according to the given value, and the valve opening adjustment rate is controlled by the programmable controller.

[0035] Feedback control of discharge valve opening: The actual opening of discharge valve 3 is monitored in real time by a feedback sensor. The feedback value is compared with the set value to determine if there is an anomaly. If the difference between the feedback value and the set value is too large, the system automatically adjusts the opening of discharge valve 3 through the PID control loop to reduce the deviation and ensure normal operation of the device.

[0036] Automatic fault identification and troubleshooting: When the difference between the actual opening of discharge valve 3 and the set opening exceeds the set threshold, the system automatically identifies the fault through the programmable controller. The system will issue an alarm and automatically increase the opening of discharge valve 3 to eliminate the fault and ensure the continued normal operation of the device.
