[0035] In flotation production, the accurate addition of reagents is a crucial step that directly affects flotation parameters. Automatic reagent dosing devices 10 are widely used in mineral processing plants both domestically and internationally. Currently, the main methods for measuring reagent dosage on the market involve using electromagnetic or ultrasonic flow meters to achieve automated control. However, due to the often poor quality and high impurity content of reagents in many processing plants, precision instruments such as flow meters suffer from surface calcium buildup and contamination by impurities, leading to inaccurate measurements or even instrument malfunctions. This results in high maintenance costs and severely impacts the normal process flow. Therefore, this application proposes an automatic reagent dosing device 10 that improves measurement accuracy and features a simple and reliable structure.

[0036] Example 1

[0037] like Figure 1 As shown, Figure 1 This is a schematic diagram of an automatic dosing device 10 provided in an embodiment of this application. The device includes: a stirring tank 100, a delivery pump 600, a valve 200, a drug storage tank 300, a linear regulating valve 500, and a level gauge 400; the stirring tank 100 is connected to the delivery pump 600 via a pipeline; the delivery pump is connected to the drug storage tank 300 via a pipeline; the valve 200 is disposed on the pipeline connecting the delivery pump 600 and the drug storage tank 300; the level gauge 400 is disposed on the outer wall of the drug storage tank 300; and the linear regulating valve 500 is connected to the drug storage tank 300 via a pipeline.

[0038] It should be noted that the delivery pump 600 is used to deliver the medicine from the stirring tank 100 to the storage tank 300; the valve 200 is used to control the amount of medicine stored in the storage tank 300 to maintain a preset capacity value; the level gauge 400 is used to display the amount of medicine stored in the storage tank 300; and the linear regulating valve 500 is used to control the outflow rate of the storage tank 300.

[0039] Furthermore, the automatic dosing device 10 of this application can realize the following sample injection process and drug dispensing process. The sample injection process is as follows: after the drug solution is prepared by the stirring tank 100, it is delivered to the storage tank 300 by the delivery pump 600. When the capacity of the storage tank 300 reaches the preset capacity value of the storage tank 300, the delivery pump 600 is stopped by the control device 20, and the valve 200 is automatically closed.

[0040] When the magnetic level gauge 400 detects a decrease in the liquid level in the storage tank 300, it determines that the amount of medicine in the storage tank 300 has decreased. It then sends a signal to the delivery pump 600, controlling the delivery pump 600 to increase its frequency, thereby increasing the amount of medicine delivered to the storage tank 300 and maintaining the liquid level in the storage tank 300 at a preset capacity value. In this embodiment, the preset capacity value is 80% of the total capacity of the storage tank 300. In other embodiments, the preset capacity value can be set according to specific needs and is not limited here.

[0041] The dispensing process achievable by this application is as follows: The linear regulating valve 500 is opened, allowing the reagent to flow by gravity to the dosing position. A magnetic level gauge 400 is interlocked with the delivery pump 600 to ensure a constant reagent level in the storage tank 300. The dosing flow rate is controlled by adjusting the opening of the linear regulating valve 500. A regression model is established between the calibrated linear regulating valve 500 and the control device 20, allowing manual input from the flow meter to change the opening of the linear regulating valve 500.

[0042] First, representative positions of the linear control valve 500 opening were selected, such as 25%, 50%, 75%, and 100% opening. While maintaining a consistent liquid level, the flow rate at each of these openings was measured. Since the flow rate and opening of the linear control valve 500 are typically linearly correlated, a linear curve was fitted using the measured data. This curve establishes the correspondence between opening and flow rate, thus enabling the control of the chemical dosing flow rate using the opening of the linear control valve 500.

[0043] In one embodiment, the linear regulating valve 500 is fixed to the outer wall of the drug storage tank 300 by a flange.

[0044] It should be noted that when the magnetic level gauge 400 is fixed to the constant-volume storage tank 300 via a flange, the flange plays a crucial role in connection and sealing. It ensures the level gauge 400 is securely installed on the storage tank 300 and guarantees the seal at the connection point, preventing liquid leakage from the storage tank 300.

[0045] In one embodiment, the device further includes a ball valve; the ball valve is connected to the drug storage tank 300 via a pipeline. The ball valve is disposed on the pipeline connecting the linear regulating valve 500 and the drug storage tank 300; the ball valve and the linear regulating valve 500 are disposed adjacent to each other.

[0046] It should be noted that, since the ball valve and the linear regulating valve 500 are arranged adjacent to each other, the ball valve can work in conjunction with the linear regulating valve 500 for more precise flow control. For example, when the equipment is started or stopped, the ball valve can be used for coarse adjustment first, quickly opening or closing the liquid passage, and then the linear regulating valve 500 can be used for precise flow regulation. Moreover, in some special cases, such as when the linear regulating valve 500 malfunctions or needs calibration, the ball valve can temporarily control the flow to ensure that the amount of medicine dispensed from the medicine storage tank 300 can be controlled.

[0047] In one embodiment, the mixing tank 100 is provided with a stirring element; the stirring element includes a mixer disposed at the top of the mixing tank 100. The mixer drives a stirring shaft extending into the mixing tank 100 to rotate, and the bottom of the stirring shaft is provided with a plurality of stirring blades.

[0048] It should be noted that the mixing components primarily rely on a mixer mounted at the top of the mixing tank 100 as their power source. The mixer acts as a drive, rotating the mixing shaft, which extends from the top of the mixing tank 100 downwards and into its interior space. At the bottom of the mixing shaft, multiple mixing blades are arranged. These blades, as the mixing shaft rotates, process the reagent in the bottom area of ​​the mixing tank 100 and at different heights.

[0049] This application provides an automatic dosing device and flotation system. The device includes: a stirring tank, a transfer pump, a valve, a storage tank, a linear regulating valve, and a level gauge. The stirring tank is connected to the transfer pump via a pipeline. The transfer pump is connected to the storage tank via a pipeline and is used to transfer the reagent from the stirring tank to the storage tank. The valve is installed on the pipeline connecting the transfer pump and the storage tank and is used to control the amount of reagent stored in the storage tank to maintain a preset capacity value. The level gauge is installed on the outer wall of the storage tank and is used to display the amount of reagent stored in the storage tank. The linear regulating valve is installed on the outer wall of the storage tank and is used to control the flow rate of the reagent from the storage tank. The automatic dosing device proposed in this application increases measurement accuracy and has a simple and reliable structure.
