[0050] Example 1

[0051] The embodiment of the present invention provides a water replenishment control device for a slag dredger, such as Figure 1 As shown, it includes a PLC local control cabinet 1 and a water supply pipe 4, on which a water supply solenoid valve 5, a water supply electromagnetic flowmeter 9, a high-travel switch 2 and a low-travel switch 3 are provided, the high-travel switch 2 and the low-travel switch 3 are connected to a float 7 through a suspension line 6, the float 7 is located in a slag scoop machine 8, the slag scoop machine 8 is provided with an ultrasonic level meter 11, and a water outlet electromagnetic flowmeter 10 is provided on the drainage pipe of the slag scoop machine 8, the PLC local control cabinet 1 is electrically connected to the water supply solenoid valve 5, the water supply electromagnetic flowmeter 9, the water outlet electromagnetic flowmeter 10, the ultrasonic level meter 11, the high-travel switch 2 and the low-travel switch 3.

[0052] Preferably, a time relay is also included, and the time relay is electrically connected to the PLC local control cabinet 1.

[0053] The working principle and beneficial effects of the above technical solution are as follows: the water level regulation of the present invention is controlled by the high stroke switch 2 and the low stroke switch 3 connected by the float 7. When the ultrasonic liquid level meter 11 detects that the water level is lower than the set position, the low stroke switch 3 is actuated, and the signal is sent to the PLC local control cabinet 1 to start the water replenishment solenoid valve 5, so that the water replenishment solenoid valve 5 is opened for water replenishment. When the water level rises to the high water level position, the stroke switch signal is sent to the PLC local control cabinet 1 through the time relay for a delay of 5 seconds, and then disconnected to start the water replenishment solenoid valve 5 relay coil circuit and stop water replenishment. Since the water level fluctuation is easily caused by slag falling, it is necessary to add a time relay delay of 5 seconds to avoid the signal from being sent by mistake. When the low water level signal disappears, the water replenishment solenoid valve 5 is directly started. When the water temperature of the slag remover 8 exceeds 73 degrees, the automatic water replenishment is also connected to the PLC local control cabinet 1 to start the water replenishment solenoid valve circuit.

[0054] Therefore, the present invention realizes intelligent monitoring and adjustment of water level through automatic control of high-travel switch 2 and low-travel switch 3, reduces the need for manual intervention, improves the convenience and safety of operation, and introduces time relays to effectively prevent misoperation caused by water level fluctuations. When the water temperature of the slag remover exceeds 73 degrees, the system can automatically start water replenishment to avoid equipment damage or performance degradation due to excessively high water temperature, thereby protecting the safety and stability of the equipment.

[0060] In this embodiment, the slag remover water replenishment amount prediction matrix is ​​a matrix that can predict the predicted value of the water replenishment amount in the next detection cycle.

[0061] The working principle and beneficial effects of the above technical solution are as follows: the slag machine water replenishment prediction matrix makes more accurate water replenishment predictions based on historical data and real-time status, reducing errors caused by insufficient or excessive water replenishment; the water replenishment calibration submodule uses the prediction results to calibrate the water replenishment measured by the float, thereby improving the accuracy of the water replenishment measurement and ensuring that the water replenishment volume is more in line with actual needs.

[0070] In this embodiment, based on the instantaneous temperature of the furnace in each detection cycle and the comparison table of the evaporation amount of the slag scooping machine, the evaporation water consumption of the slag scooping machine 8 in each detection cycle is determined. When the instantaneous temperature of the furnace in the detection cycle of the corresponding cycle is between the two temperatures in the comparison table of the evaporation amount of the slag scooping machine, the temperature with the smallest difference with the instantaneous temperature is taken.

By establishing the evaporation water consumption prediction matrix of the slag removal machine and the slag removal water consumption prediction matrix, it is possible to systematically integrate historical data and real-time collected data to form a dynamic and updateable prediction model, which provides a reliable basis for future water replenishment needs.

[0102] On the basis of Example 2, the water replenishment calibration submodule calibrates the water replenishment amount directly obtained by the PLC local control cabinet 1 based on the ultrasonic level meter 11 based on the water replenishment amount prediction value of the next detection cycle determined by the water replenishment amount prediction submodule, including:

[0103] Among them, E +1 is the amount of water replenished after calibration in the i+1th detection cycle, D +1 is the amount of water replenishment before calibration directly obtained by the PLC local control cabinet 1 based on the ultrasonic level meter 11 in the i+1th detection cycle, C +1 is the predicted value of water replenishment in the i+1th detection cycle, and α is the calibration coefficient.

[0104] The working principle and beneficial effects of the above technical scheme are as follows: the water replenishment calibration submodule calibrates the pre-calibration water replenishment amount directly obtained by the PLC local control cabinet 1 based on the ultrasonic liquid level meter 11 in the i+1th detection cycle, so that the float water replenishment amount obtained in actual operation is more consistent with the predicted value determined by the water replenishment amount prediction submodule. First, the predicted value is used as a reference to calculate the calibration coefficient, and then the pre-calibration water replenishment amount directly obtained by the PLC local control cabinet 1 based on the ultrasonic liquid level meter 11 is adjusted to ensure that it accurately reflects the predicted needs, which significantly improves the accuracy of water replenishment control and reduces the deviation caused by float measurement errors or equipment drift, thereby optimizing the utilization efficiency of water resources and improving the overall stability and operation performance of the system.

[0110] Data monitoring and log recording are used to monitor the real-time operating data of the water replenishment control device and record the operation log for troubleshooting and system maintenance.

[0111] In this embodiment, the real-time operating data of the water replenishment control device includes the real-time flow of the water replenishment pipe 4, the working status of the water replenishment solenoid valve 5, the real-time liquid level detected by the float 7, the sensitivity of the high travel switch 2 and the sensitivity of the low travel switch 3.

[0113] In this embodiment, the context information of the real-time operation data of the water replenishment control device includes the collection time, the data source, and the current state of the device.

[0114] The working principle and beneficial effects of the above technical solution are as follows: the data recording module significantly improves the efficiency of data management and system maintenance by systematically collecting, storing, marking and monitoring the real-time operation data of the water replenishment control device. The equipment data acquisition unit obtains key data such as the water replenishment pipe flow, solenoid valve status, float liquid level and switch sensitivity in real time. The data storage unit converts these data into a standard format (such as CSV, JSON or XML) to ensure the uniformity of the data and facilitate subsequent analysis. The data tag unit adds contextual information (such as collection time, data source and equipment status) to make data easier to classify and query. Data monitoring and logging provide real-time monitoring and operation log recording functions, which are helpful for rapid problem detection and system maintenance, thereby improving the stability, reliability and management efficiency of the system.
