[0030] Refer to Figures 1 - 4 , a high-concentration flotation medium regulating system for a flotation machine, comprising a liquid supply bucket 1, a liquid storage tank 2, a flotation cell 3, a cleaning mechanism 4, a reflux mechanism 5 and a control system, wherein:

[0031] The overall shape of the liquid supply bucket 1 is circular columnar, with an opening at the top. Through the opening, liquid flotation medium (such as; brine, calcium chloride water, etc.) can be stored inside.

[0032] A stirring mechanism is installed inside the liquid supply bucket 1. The stirring mechanism may include a motor 100 and stirring blades. The motor 100 is installed at the top end of the liquid supply bucket 1, and the stirring blades are located inside the liquid supply bucket 1. The output shaft of the motor 100 is connected to the top rod body of the stirring blades. Water and flotation solutes (such as: salt, calcium chloride) are put into the liquid supply bucket 1, and they can be quickly stirred and dissolved by the stirring mechanism.

[0033] A supply pipeline 101 is installed on the liquid storage tank 2. The supply pipeline 101 is arranged between the liquid supply bucket 1 and the liquid storage tank 2. The drain port of the liquid supply bucket 1 is connected to the liquid storage tank 2 through the supply pipeline 101. The liquid flotation medium inside the liquid supply bucket 1 can be transmitted to the liquid storage tank 2 through the supply pipeline 101.

[0034] A conveying mechanism 301 is installed on the flotation cell 3. The conveying mechanism 301 includes a water pump 302 and a supply pipeline 303. The water pump 302 is installed inside the liquid storage tank 2. One end of the supply pipeline 303 is installed at the outlet end of the water pump 302, and the other end is installed on the flotation cell 3, for supplying the flotation medium in the liquid storage tank 2 to the flotation cell 3.

[0035] The cleaning mechanism 4 includes a hoist 401, a vibrating screen barrel 402 and a sedimentation tank 403.

[0036] The hoist 401 can be a spiral hoist with a spiral lifting shaft inside. The hoist 401 is installed at the bottom outlet of the flotation cell 3. At this time, the inlet end of the hoist 401 is sealed and installed together with the bottom outlet end of the flotation cell 3. The discharge port of the hoist 401 is connected to the vibrating screen barrel 402. Specifically, a transmission pipe 404 is installed between the discharge port of the hoist 401 and the vibrating screen barrel 402.

[0037] The hoist 401 can make the particulate impurities, silt and part of the liquid flotation medium precipitated at the bottom of the flotation cell 3 be transmitted along the transmission pipe 404 to the vibrating screen barrel 402.

[0038] The sedimentation tank 403 is located at the drain port of the vibrating screen barrel 402. The vibrating screen barrel 402 can filter the particulate impurities in the liquid flotation medium conveyed from the transmission pipe 404 and output the filtered liquid flotation medium into the sedimentation tank 403.

[0039] The sedimentation tank 403 and the liquid storage tank 2 are integrally arranged and connected to each other. Specifically, the height of the partition 12 between the sedimentation tank 403 and the liquid storage tank 2 is lower than the height of the surrounding walls. The flotation medium in the sedimentation tank 403 can overflow into the liquid storage tank 2, so that the flotation medium in the sedimentation tank 403 can be supplied into the liquid storage tank 2. At this time, the liquid flotation medium in the liquid storage tank 2, the flotation tank 3 and the sedimentation tank 403 can form a circulation system.

[0040] The reflux mechanism 5 is arranged between the liquid storage tank 2 and the liquid supply bucket 1. The reflux mechanism 5 includes a second water pump 501 and a third supply pipeline 502. The second water pump 501 is installed in the liquid storage tank 2. One end of the third supply pipeline 502 is installed on the outlet end of the second water pump 501, and the other end is installed on the liquid supply bucket 1.

[0041] A concentration detector 6 for detecting the concentration of the flotation medium is installed inside the liquid storage tank 2. The concentration detector 6 can be an electronic salinometer. A concentration threshold of the concentration detector 6 is preset in the control system. The concentration detector 6 and the stirring mechanism are both electrically connected to the control system. When the concentration of the flotation medium in the liquid storage tank 2 is lower than the preset threshold of the concentration detector 6, the stirring mechanism in the liquid supply bucket 1 is started to stir the added solutes (such as salt, calcium chloride) and water to promote their dissolution, so as to increase the concentration of the flotation medium.

[0042] Due to the filtration and sedimentation of the cleaning mechanism 4, the liquid flotation medium circulating between the liquid storage tank 2, the flotation tank 3 and the sedimentation tank 403 is consumed, and the concentration of the liquid flotation medium decreases. According to the concentration threshold preset in the control system, the concentration detector 6 can also control the operation of the second water pump 501 in the reflux mechanism 5. The reflux mechanism 5 is used to return the low-concentration flotation medium in the liquid storage tank 2 to the liquid supply bucket 1 to increase the concentration of the flotation medium (flotation solutes, such as salt or calcium chloride, can be added to the liquid supply bucket 1 to increase the concentration). The liquid supply bucket 1 can supply the high-concentration flotation medium into the liquid storage tank 2 through the first supply pipeline 101, and the flotation medium in the liquid storage tank 2 can be transported to the flotation tank 3, thus completing the adjustment of the concentration of the flotation medium in the flotation tank 3.

[0043] In this embodiment, the liquid flotation medium in the liquid storage tank 2 can be supplied to the flotation tank 3 through the first water pump 302 and the second supply pipeline 303. The elevator 401 can transport the particulate impurities, sludge, and part of the liquid flotation medium precipitated at the bottom of the flotation tank 3 along the transmission pipe 404 to the vibrating screen barrel 402. The vibrating screen barrel 402 can filter the particulate impurities in the liquid flotation medium conveyed from the transmission pipe 404 and output the filtered liquid flotation medium into the sedimentation tank 403. The liquid flotation medium with a decreased concentration in the sedimentation tank 403 can then flow back to the liquid storage tank 2. At this time, the liquid flotation medium in the liquid storage tank 2, the flotation tank 3, and the sedimentation tank 403 constitutes a circulating system. When the concentration of the flotation medium in the liquid storage tank 2 is lower than the preset threshold of the concentration detector 6, the reflux mechanism 5 is used to make the low-concentration flotation medium in the liquid storage tank 2 flow back to the supply bucket 1 to increase the concentration of the flotation medium. In addition, the supply bucket 1 can supply the high-concentration flotation medium to the liquid storage tank 2 through the first supply pipeline 101, thereby being able to adjust the concentration of the flotation medium in the flotation tank 3. The flotation equipment has the function of adjusting the concentration of the flotation medium, can provide a suitable and reliable flotation medium during the flotation process, and improves the working efficiency of the flotation equipment.

It can be an electric heating element, a heating pipe, or other heating devices. The first temperature control switch is electrically connected to the first heating mechanism 7 and is used to control the first heating mechanism 7 to automatically turn on or off.

[0045] In this embodiment, when the first temperature control switch detects that the temperature in the supply bucket 1 reaches the preset upper limit temperature, it will trigger and turn off the first heating mechanism 7 to prevent the temperature from rising further. Similarly, when the temperature drops to the preset lower limit temperature, the first temperature control switch will turn on the first heating mechanism 7 again to keep the temperature of the liquid flotation medium inside the supply bucket 1 within the required range, thereby being able to regulate the temperature of the liquid flotation medium in the supply bucket 1 to increase the solubility of the solute and obtain a high-concentration liquid flotation medium.

[0046] In a possible embodiment, as Figure 3 shown, a first float switch 8 is provided in the liquid storage tank 2, and the first float switch 8 is installed at the outlet of the first supply pipeline 101.

[0048] In a possible embodiment, as Figure 3As shown, a second heating mechanism 9 and a second temperature control switch are installed in the liquid storage tank 2. The second temperature control switch can preset a temperature threshold.

The second temperature control switch is electrically connected to the second heating mechanism 9 and is used to control the second heating mechanism 9 to automatically turn on or off.

[0049] In this embodiment, when the second temperature control switch detects that the temperature in the liquid storage tank 2 reaches the preset upper limit temperature, it will trigger and turn off the second heating mechanism 9 to prevent the temperature from rising further; similarly, when the temperature drops to the preset lower limit temperature, the second temperature control switch will turn on the second heating mechanism 9 again to keep the temperature of the liquid flotation medium in the liquid storage tank 2 within the required range, thereby avoiding the situation where solute crystals precipitate due to the decrease in the solution temperature, resulting in a decrease in the concentration of the solution.

[0050] In a possible embodiment, as Figure 2 shown, a second float switch 10 is provided in the flotation tank 3. A sensor is integrally installed on the second float switch 10. The first water pump 302 and the second float switch 10 are both electrically connected to the control system. The second float switch 10 can set to start or stop the first water pump 302 according to the liquid level height of the flotation tank 3 to ensure the stability of the liquid level height in the flotation tank 3.

[0051] In a possible embodiment, as Figure 1 shown, a third heating mechanism 11 and a third temperature control switch are installed in the flotation tank 3. The third temperature control switch can preset a temperature threshold. The third heating mechanism 11 is used to heat the liquid in the flotation tank 3, and it can be an electric heating element, a heating pipe or other heating devices. The third temperature control switch is electrically connected to the third heating mechanism 11 and is used to control the third heating mechanism 11 to automatically turn on or off.

[0052] In this embodiment, when the third temperature control switch detects that the temperature in the flotation tank 3 reaches the preset upper limit temperature, it will trigger and turn off the third heating mechanism 11 to prevent the temperature from rising further; similarly, when the temperature drops to the preset lower limit temperature, the third temperature control switch will turn on the third heating mechanism 11 again to keep the temperature of the liquid flotation medium in the flotation tank 3 within the required range, thereby avoiding the situation where solute crystals precipitate due to the decrease in the solution temperature, resulting in a decrease in the concentration of the solution.
