Description

Technical Field

[0001] The present application relates to the technical field of gas spray gun detection, and in particular to a flotation column gas spray gun blockage detection device. Background Art

[0002] The gas source of the existing flotation column gas spray gun is transmitted to the gas spray gun through the spray gun gas source interface, and then the gas is sprayed into the flotation column. During the use of the spray gun, calcium is easily deposited inside. The main components of calcium deposition are impurities such as calcium carbonate, calcium sulfate, and iron hydroxide. When the impurity content in the spray gun is high, it will not only affect the use of the spray gun, but also seriously block the spray gun nozzle and damage the spray gun. The detection of spray gun blockage is usually done by the operator directly touching the leaking part of the spray gun, feeling the temperature, and judging whether the spray gun is blocked based on experience.

[0003] This blockage detection method is subject to interference from human factors and can only make a judgment after blockage. In this process, since the blockage rate of the spray gun is gradually formed, under the condition of a certain gas source flow rate, the work efficiency gradually decreases as the gas spray gun gradually becomes blocked, resulting in fluctuations in mineral processing indicators. Utility Model Content

[0004] In order to solve or partially solve the problems existing in the related technology, the present application provides a flotation column gas spray gun blockage detection device, which calculates the blockage rate based on the gas flow rate, and then adjusts the gas flow in the gas spray gun to achieve spray gun gas flow control and improve the flotation column production indicators.

The gas spray gun is inserted into the flotation column, and the air outlet end of the gas spray gun is connected to the second gas flow meter. The first gas flow meter, the second gas flow meter, the gas source are connected to the human-computer interaction module, and the human-computer interaction module is also connected to the on-site sound and light warning device.

[0007] Furthermore, the human-computer interaction module includes a PLC control unit and an HMI text display unit, and the HMI text display unit is used to form records for human-computer interaction query trends.

[0008] Furthermore, the PLC control unit calculates the blockage rate of the spray gun through the detection values ​​of the first gas flow meter and the second gas flow meter, and the PLC control unit controls the switch of the on-site sound and light warning device based on the preset alarm threshold of the blockage rate.

[0009] Furthermore, it also includes a display module, which is connected to the human-computer interaction module.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0022] As shown in the figure, a flotation column gas spray gun blockage detection device comprises:

[0023] Gas source 1, gas spray gun 2, flotation column 3, first gas flow meter 4, human-computer interaction module 5, on-site sound and light warning device 6, second gas flow meter 7, display module. The air inlet end of the first gas flow meter 4 is connected to the gas source 1, and the other end is connected to the gas source interface of the gas spray gun 2. The gas spray gun 2 is inserted into the flotation column 3 to form a gas supply system, and the second gas flow meter 7 is connected to the gas outlet of the gas spray gun 2. When installing the second gas flow meter 7, it is necessary to select a suitable gas flow meter model and specification according to actual needs to ensure that it can meet the detection requirements and is suitable for installation at the outlet of the spray gun, and to ensure that the installation of the gas flow meter will not affect the normal use of the spray gun and avoid the flow meter blocking or interfering with the gas and liquid circulation channels.

[0024] When installing the first gas flow meter 4 and the second gas flow meter 7, it is necessary to ensure that they are properly calibrated and adjusted to ensure the accuracy and stability of the measurement results. At the same time, the gas flow meter needs to be regularly inspected and maintained to ensure its normal operation. The first gas flow meter 4, the second gas flow meter 7, the gas source 1 and the human-computer interaction module 5 are connected.

[0025] The human-computer interaction module 5 includes a PLC control unit and an HMI text display unit. The first gas flow meter 4 detects the input flow of the gas spray gun 2, and the second gas flow meter 7 detects the output flow of the gas spray gun 2. The PLC control unit receives the input flow and output flow data in real time and obtains the blockage rate of the gas spray gun 2 based on the data. The HMI text display unit is used to form records for human-computer interaction query trends.

[0026] The control interval and alarm threshold are preset in the PLC control unit. On the one hand, the PLC control unit is connected to the gas source 1, and the gas source valve is adjusted according to the blockage rate to realize the control of the input flow of the gas spray gun 2. When the blockage rate is high, the gas flow in the gas spray gun is increased, and vice versa, to avoid fluctuations in mineral processing indicators; on the other hand, the human-computer interaction module 5 is also connected to the on-site sound and light warning device 6. When the blockage rate data of the gas spray gun 2 calculated by the human-computer interaction module 5 reaches the set alarm threshold, the PLC control unit generates a switching signal and turns on the on-site sound and light warning device 6 to remind the operator to replace and repair the spray gun, so as to prevent the operator from making judgments based on experience after the gas spray gun is blocked, causing production stagnation.

[0027] The display module is connected to the human-machine interaction module 5. The real-time gas flow rate, blockage rate and other data of the gas spray gun 2 are transmitted to the display module through the human-machine interaction module and displayed intuitively to the operator. The operator can check the flow rate and the blockage trend of the gas spray gun 2, grasp the real-time status of the spray gun, and make a practical maintenance plan.

[0028] Finally, it should be noted that, in this article, relationships such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms include, include or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
