[0028] It needs to be explained that when the flotation device is used for flotation of fluorite material, the prepared fluorite material is introduced into the flotation tank 1 through the feed pipe 8 and mixed with an appropriate amount of water, and according to the flotation requirements, the flotation reagents are added in proportion, including collectors (such as fatty acids, sulfonic acids, etc.), foaming agents (such as pine oil, kerosene, etc.) and adjusting agents (such as lime, sulfuric acid, etc.); and air is introduced into the stirring and discharging assembly 3 through the air inlet pipe 9, then the driving shaft 2 is controlled to rotate, driving the stirring and discharging assembly 3 to stir the ore pulp to form ore pulp with a certain concentration, and generate bubbles, and the required ore is extracted by flotation. Finally, under the action of the foam scraping plate 4, the bubbles generated by flotation are scraped off from the foam outlet 6 and collected.

[0029] Specifically, the top of the flotation tank 1 is provided with a motor, and the output end of the motor is connected with the driving shaft 2 for driving the driving shaft 2 to rotate.

[0030] Further, the driving shaft 2 is coaxially and spaced apart on the outside of the sleeve 5, and the pipe body of the sleeve 5 is provided with the feed pipe 8 and the air inlet pipe 9 on the outside and inside thereof, respectively, and the bottom end of the sleeve 5 is coaxially and fixedly provided with a distribution disc 18, and the distribution disc 18 is rotatably arranged opposite to the stirring and discharging assembly 3.

[0031] Among them, the feed pipe 8 and the air inlet pipe 9 are fixedly connected with the sleeve 5 and the flotation tank 1 respectively, so as to fix the position of the sleeve 5, so that the fluorite material and air directly enter the stirring and discharging assembly 3 through the gap between the sleeve 5 and the driving shaft 2, which is beneficial to uniform stirring of the material and rapid generation of bubbles.

[0032] Further, the stirring and discharging assembly 3 comprises: a fixed disc 10 coaxially and fixedly arranged at the bottom end of the driving shaft 2, the distribution disc 18 passes through the fixed disc 10 and is rotatably arranged opposite to the fixed disc 10, the bottom end of the fixed disc 10 is uniformly distributed with a plurality of stirring blades 13 in the circumferential direction, the extension direction of the stirring blades 13 points to the center of the fixed disc 10, and a plurality of arc plates 14 are circumferentially arranged between the outer periphery of the bottom of the fixed disc 10 and the stirring blades 13, and the outer arc surface of the arc plate 14 is arranged towards the center of the fixed disc 10.

[0033] It needs to be explained that when the fluorite ore slurry is stirred, the fluorite material and air are stirred outwardly by the stirring blade 13 through the feeding of the distributing disc 18 and the air inlet, and then further stirred by the arc plate 14. During the rotation of the arc plate 14 with the fixed disc 10, the arc plate 14 is divided into two parts towards the rotating direction, and then a turbulent flow is formed at the arc surface to accelerate the uniform stirring of the fluorite material and the generation of air bubbles.

[0034] Further, the top end of the arc plate 14 is vertically fixed with a short shaft, and the arc plate 14 is rotationally connected with the fixed disc 10 through the short shaft.

[0035] The fixed disc 10 is provided with a guide groove 15 along the rotation track of any end of the arc plate 14, and a rotating shaft 16 is rotationally limited on the end of the guide groove 15.

[0037] It needs to be explained that when the fluorite slurry is stirred, the deflection angle of the arc plate 14 is adjusted by the extension and retraction of the electric telescopic rod 17, and then the relative cutting angle of the arc plate 14 and the slurry is changed, the stirring intensity of the arc plate 14 on the slurry is changed, and the efficient stirring of the slurry or the flotation reagent of different concentrations is adapted.

[0039] It needs to be explained that after the flotation is finished, the ore residues are left at the bottom of the flotation tank 1, and due to the arrangement of the stirring assembly, the residues are often difficult to clean. By adjusting the deflection angle of the arc plate 14, when the arc plate 14 is overlapped on the stirring blade 13, a structure similar to a scraper is formed to scrape off the ore residues, and the ore residues are scraped to the residue discharge port 7 under the action of the arc plate 14, and the cleaning efficiency is improved.

[0041] Specifically, after the fluorite material body falls from the discharging hole or the discharging groove, the fluorite material body is stirred outward by the stirring blade 13 to avoid the fluorite material body from piling up. Meanwhile, the material body and the air adding position are located at the stirring center position, which can ensure the rapid and uniform stirring of the fluorite material body and the rapid generation of bubbles.

[0042] Further, the feeding pipe 8 and the air pipe 9 are located at opposite sides of the sleeve 5 respectively, and the air pipe 9 is located higher than the feeding pipe 8, which utilizes the air to push the fluorite material body to accelerate the falling of the fluorite material body, and meanwhile avoids the discharging hole or the discharging groove from being blocked.

[0043] In specific implementation, appropriate fluorite material body, water and flotation reagent are put into the flotation tank, the motor is started to drive the stirring and deslagging assembly to stir the ore pulp mixture and generate bubbles, then the foam is collected by the scraping plate to realize the flotation extraction of the required mineral; wherein, the arc plate angle can be adjusted by controlling the extension length of the electric telescopic rod, thereby adjusting the stirring intensity of the device and improving the applicability of the device. After the flotation is completed, the electric telescopic rod is controlled to be retracted, so that the arc plate is lapped on the stirring blade to form a scraping structure, the bottom mineral residue is scraped and rotated to be discharged from the deslagging port.
