[0029] The utility model is further described below in conjunction with the accompanying drawings:

[0030] like Figure 1 — Fig. 9As shown, a stirring flotation machine for mineral processing comprises a flotation box 101, wherein the flotation box 101 is provided with a scraping mechanism on both sides thereof, the top of the flotation box 101 is connected with a bearing platform 102 by bolts, the side of the flotation box 101 is connected with a feed pipe 103 and a vent pipe 104 by bolts, a power mechanism is installed on the bearing platform 102, a mixing mechanism and a guiding mechanism driven by the power mechanism are arranged in the flotation box 101, the mixing mechanism comprises a bottom shell 301, the feed pipe 103 leads into the bottom shell 301, the bottom shell 301 is connected to the bottom of the inner wall of the flotation box 101 by bolts, a rotating table 302 is rotatably connected in the bottom shell 301, a plurality of annularly arranged connecting columns 303 are connected to the top of the rotating table 302 by bolts, the power mechanism comprises a rotating shaft 204 for driving the rotating table 302 to rotate, and the top of the connecting column 303 is connected with Impeller 304, the slurry is fully mixed with the gas in the bottom shell 301, and the slurry mixed with the gas is discharged from the impeller 304 and floated in the flotation box 101. A connecting block 305 is welded on the inner side of the connecting column 303, and a rotating ring 306 is connected to the inner side of the connecting block 305 by bolts. The top of the rotating ring 306 is rotatably connected to the air supply pipe 307. A pressurizing mechanism for adjusting the air pressure at the outlet end of the air supply pipe 307 according to the viscosity of the mortar is installed on the connecting block 305 and the rotating ring 306. A material passing channel 308 is left on the inner side of the air supply pipe 307 and the rotating ring 306. The ventilation pipe 104 is welded to the air inlet position at the top of the air supply pipe 307. After the slurry enters the bottom shell 301 from the supporting platform 102, the connecting column 303 stirs the slurry and fully mixes it with the gas introduced into the air supply pipe 307, thereby improving the degree of mixing.

[0031] In this embodiment, the pressure mechanism includes a pressure rod 401, which is slidably connected to one side of the connecting block 305 in the direction of rotation. A wedge block 402 is slidably connected to one side of the pressure rod 401, and a connecting piece 403 is connected to one side of the wedge block 402 by bolts. A return spring 404 is installed between the connecting piece 403 and the impeller 304. The wedge block 402 is slidably connected to the inside of the connecting block 305, and one end of the wedge block 402 extends into the rotating ring 306. The end of the wedge block 402 extending into the rotating ring 306 is screwed in The bolt is connected with a pressure block 405, and the pressure block 405 is used to extend into the outlet end of the air supply pipe 307 to increase the air pressure when the pressure rod 401 is under pressure. When the slurry concentration is relatively high, the slurry exerts a certain pressure on the pressure rod 401, and the pressure rod 401 squeezes the wedge block 402 and moves it toward the center of the rotating ring 306. The wedge block 402 overcomes the air pressure in the air supply pipe 307 and the elastic force of the return spring 404 to push the pressure block 405 to move, thereby increasing the air pressure at the outlet end of the air supply pipe 307, so that the gas disperses the slurry and mixes it more fully.

[0032] In this embodiment, the power mechanism includes a No. 1 motor 201, which is connected to the top of the support platform 102 by bolts. A No. 1 belt 202 is sleeved on the output end of the No. 1 motor 201, and a driving wheel 203 is sleeved on the other end of the No. 1 belt 202. The rotating shaft 204 is connected to the bottom of the driving wheel 203 by bolts. The upper end of the air supply pipe 307 is rotatably connected to the lower end of the driving wheel 203 to ensure a certain degree of sealing. The rotating shaft 204 passes through the inside of the air supply pipe 307, and the gas passes between the rotating shaft 204 and the air supply pipe 307 and enters the bottom shell 301.

[0033] In this embodiment, the guiding mechanism includes two fixed shells 501 arranged symmetrically with respect to the center, and an auger shaft 502 is rotatably connected inside the fixed shell 501. A notch is provided on the opposite side of the fixed shell 501 for guiding the foam to move toward the scraping mechanism. When the auger shaft 502 rotates, the foam floating to the left and right sides of the flotation box 101 is pushed to the front and rear positions by the auger shaft 502, which is helpful to accelerate the scraping of the foam by the scraping mechanism and prevent the foam with concentrate from sticking to the side wall of the flotation box 101. One end of the auger shaft 502 is rotatably connected to the installation box 503, and the installation box 503 is connected to the inner wall of the flotation box 101 by bolts. One end of the auger shaft 502 is welded with a No. 1 bevel gear. Wheel 504, a No. 2 bevel gear 505 is meshed on the No. 1 bevel gear 504, a transmission rod 506 is welded on the top of the No. 2 bevel gear 505, and the transmission rod 506 is rotatably connected to the installation box 503. The top of the driving wheel 203 is connected to the passive wheel 205 by bolts, and a No. 2 belt 206 is sleeved between the passive wheel 205 and the transmission rod 506. When the driving wheel 203 rotates, the passive wheel 205 rotates synchronously with the driving wheel 203, thereby driving the transmission rod 506 to rotate through the two No. 2 belts 206, and through the meshing action of the No. 2 bevel gear 505 and the No. 1 bevel gear 504, the auger shaft 502 is driven to rotate, thereby accelerating the flotation efficiency of the foam.

[0034] In this embodiment, the scraping mechanism includes a scraping bin 601, which is fixedly installed on the front and rear sides of the flotation box 101. The top of one side of the scraping bin 601 is connected to a No. 2 motor 602 by bolts, and the output end of the No. 2 motor 602 is connected to a scraper 603 by bolts. A collection bin (not shown in the figure) is arranged on the outside of the scraping bin 601.

[0035] Working principle: When the device is in use, the slurry is passed into the bottom shell 301 through the feed pipe 103, and the gas is passed into the gas supply pipe 307 through the support platform 102, and finally mixed with the slurry in the bottom shell 301. At the same time, the connecting column 303 plays a stirring role to make the mixing more complete. When the slurry concentration is relatively high, the slurry exerts a certain pressure on the pressure rod 401, and the pressure rod 401 squeezes the wedge block 402 and moves it toward the center of the rotating ring 306. The wedge block 402 overcomes the air pressure in the gas supply pipe 307 and the elastic force of the return spring 404 to push the pressure block 405 to move, increase the air pressure at the outlet end of the gas supply pipe 307, and make the gas disperse the slurry. , the mixing is more complete, the slurry is fully mixed with the gas in the bottom shell 301, and the slurry mixed with the gas is discharged by the impeller 304 into the flotation box 101, and the concentrate with bubbles floats on the top. When the driving wheel 203 rotates, the passive wheel 205 rotates synchronously with the driving wheel 203, thereby driving the transmission rod 506 to rotate through the two No. 2 belts 206, and driving the auger shaft 502 to rotate through the meshing action of the No. 2 bevel gear 505 and the No. 1 bevel gear 504, so as to prevent the foam from sticking to the side wall of the flotation box 101 and accelerate the flotation efficiency of the foam, and finally scrape the foam out of the flotation box 101 through the scraper 603 to complete the flotation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
