[0002] The flotation machine is driven by a motor and V-belt to rotate the impeller, which generates centrifugal force and creates negative pressure. On the one hand, it draws in sufficient air to mix with the slurry, and on the other hand, it stirs the slurry and mixes with reagents. At the same time, it refines the foam, causing the minerals to adhere to the foam and float to the surface of the slurry to form mineralized foam. By adjusting the height of the gate, the liquid level is controlled, and the useful foam is scraped off by the scraper to achieve the purpose of mineral beneficiation.

[0003] During the flotation process, one or more reagents need to be added to the flotation machine. The types of reagents added include inhibitors, activators, modifiers, collectors, etc. The existing reagent addition operation is mostly controlled manually, which cannot accurately control the amount of reagent added to achieve automated control. It is not easy to guarantee the beneficiation efficiency and stability. In addition, the reagents will adhere to the inner wall of the dosing tank, making it difficult to guarantee the utilization rate of the reagents and affecting the dispersion effect of the reagents.

[0004] Developing an automatic dosing device for flotation machines to precisely and automatically control the dosage of various reagents, reduce reagent adhesion to the inner wall of the dosing tank, and ensure the dispersion efficiency of reagents in the flotation machine has become a technical problem that urgently needs to be solved by those skilled in the art.

[0028] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] like Figure 1-3 As shown, an automatic dosing device for a flotation machine includes a main dosing pipe 11, a flotation machine 12, and a dosing branch pipe 13. The main dosing pipe 11 is connected to multiple flotation machines 12 through the dosing branch pipe 13, and a solenoid valve 14 is installed on the dosing branch pipe 13. The other end of the main dosing pipe 11 is connected to a stirring assembly, and can add reagents to multiple flotation machines through the dosing branch pipe.

[0030] A bracket 9 is installed on the lower surface of the stirring assembly 8, and an electronic scale 10 is installed on the bracket 9. The electronic scale can measure the weight inside the stirring assembly and the drug storage assembly, which facilitates targeted drug addition.

[0031] A motor 15 is installed in the middle of the upper surface of the stirring assembly 8, and a drug storage assembly is evenly installed around the upper surface of the stirring assembly 8, and the drug storage assembly is connected to the stirring assembly 8.

[0032] The working end of the motor 15 is connected to the stirring assembly for transmission.

[0033] Specifically, the stirring assembly 8 includes a stirring cover 801 and a stirring tank 805, wherein the stirring cover 801 is sealed to the upper opening of the stirring tank 805 by bolts 802;

[0034] The motor 15 is installed on the upper surface of the stirring cover 801, and the lower opening of the stirring tank 805 is connected to the dosing main pipe 11;

[0035] A fixing frame 807 is installed on the inner side wall of the mixing tank 805. The fixing frame 807 is movably connected to the stirring column 803. The upper end of the stirring column 803 is connected to the motor 15 for transmission.

[0036] Stirring rods 804 are installed at equal intervals on the outer side wall of the stirring column 803. A scraper 806 is slidably installed on the free end of the stirring rod 804. The stirring rod can fully stir and mix the medicine and the liquid. At the same time, the scraper can scrape the inner side wall of the mixing tank to prevent the medicine from adhering to the tank and affecting the efficiency of the medicine and the subsequent preparation ratio.

[0037] Specifically, a laser rangefinder 16 is installed on the lower surface of the stirring cover 801. The laser rangefinder can measure the liquid level inside the stirring tank, which facilitates the preparation of the ratio of medicine and liquid.

[0038] Specifically, a heating rod 17 is installed on the upper surface of the fixing frame 807, and a thermocouple 18 is installed on the inner side wall of the mixing tank 805. The thermocouple 18 is installed below the fixing frame 807. The heating rod can heat the liquid medicine inside the mixing tank, which facilitates the full mixing of the medicine and the liquid.

[0039] Specifically, the drug storage assembly includes a drug storage tank 6, the lower end of which is connected to the upper surface of the stirring cover 801 via a connecting post 5, and the drug storage tank 6 is connected to the stirring tank 805 via a discharge pipe;

[0040] The feed pipe is equipped with a metering valve 7, which can control the dosage of the agent and ensure the accuracy of the mixing ratio.

[0041] Specifically, it also includes a liquid addition pipe 1 and a gas addition pipe 2. Both the liquid addition pipe 1 and the gas addition pipe 2 are connected to the outer wall of the mixing tank 805. The liquid addition pipe 1 is equipped with a liquid flow valve 3, and the gas addition pipe 2 is equipped with a gas flow valve 4. The liquid addition pipe can add liquid into the mixing tank to facilitate the dissolution of the reagent. At the same time, the gas addition pipe can introduce gas into the mixing tank. On the one hand, the mixed reagent can be pushed into the flotation machine under the action of air pressure. On the other hand, the gas addition pipe can also introduce gas into the flotation machine to increase the air intake inside the flotation machine and facilitate the formation of foam inside the flotation machine.

[0042] Specifically, it also includes a PLC controller. The liquid flow valve 3, the gas flow valve 4, the metering valve 7, the electronic scale 10, the motor 15, the laser rangefinder 16, the heating rod 17 and the thermocouple 18 are all electrically connected to the PLC controller to achieve precise and automated control.

[0043] During operation, liquid is added to the mixing tank through the liquid addition pipe, the liquid level is controlled by a laser rangefinder, and the weight of the added liquid is weighed by an electronic scale. Furthermore, the density of the liquid is obtained, and the type of added liquid is confirmed.

[0044] At this time, the storage tank adds the medicine to the mixing tank according to the weight and type of the liquid and the preset ratio. The dosage of the added medicine is precisely controlled by the metering valve, which makes it convenient to add the preset weight of medicine to the liquid. The amount of human intervention in the medicine addition process is small, which helps to ensure the accuracy of medicine addition.

[0045] After addition, the motor drives the stirring column, stirring rod and scraper to stir, accelerate the mixing of the agent and the liquid, and activates the heating rod as needed to heat the agent and the liquid, improve the mixing efficiency of the agent and the liquid. The temperature of the liquid is controlled by thermocouples to avoid the temperature being too high or too low and affecting the mixing effect.

[0046] After mixing, high-speed gas is introduced into the mixing tank through the gas supply pipe, and the solenoid valve on the dosing pipe is opened accordingly. The mixed reagent is then introduced into the flotation machine through the high-speed gas. This ensures the gas content inside the flotation machine and blows all the reagent into the flotation machine through air blowing, preventing the reagent from remaining inside the mixing tank.
