[0028] By adopting the above scheme, when the slurry enters the stirring tank 1, the liftable stirring device starts to stir the slurry, and the liftable stirring device can automatically control the lifting and lowering, thereby strengthening the disturbance of the slurry in the stirring tank 1 and improving the mixing efficiency; the slurry generates bubbles through the foam generating cover under the stirring action, and the grid structure of the foam generating cover increases the contact area between the slurry and the air, thereby improving the foaming efficiency, and the bubbles carry the extracted mineral components to the surface of the slurry to form froth; the froth is scraped into the froth tank 2 by the automatic scraper device, and the automatic scraper can automatically adjust the height of the scraper device according to the liquid level in the stirring tank 1 detected by the liquid level meter 3, thereby avoiding the waste of resources caused by the unreasonable scraper height; the froth remaining on the automatic scraper device is scraped into the froth tank 2 by the cleaning device, thereby improving the scraping efficiency, thereby completing the slurry flotation, and the froth is transported to the next process.

[0029] Further, the foamed side plate 8 is a ring-shaped grid structure;

[0030] Furthermore, the guide bottom plate 9 is provided with circular guide holes;

[0035] Among them, the front end shaft 19 and the rear end shaft 20 drive the crank 21 to rotate, and the front end of the connecting rod a22 is connected to the connecting rod journal 27 in the crank 21, so that rotating the crank 21 can drive the connecting rod a22 to swing, and the connecting rod a22 drives the connecting rod b23 to reciprocate back and forth in the slide frame 24, so that the cleaning scraper 25 installed on the slide frame 24 can scrape off the floating foam attached to the scraper, thereby improving the scraping efficiency.

[0036] Furthermore, the froth tank 2 is provided with an oblique body 29 in the tank on one side connected to the stirring tank 1;

[0037] The froth scraped off by the scraper can slide along the inclined body 29 into the froth trough 2, thereby improving the froth conveying efficiency.

[0038] In summary, the device includes a stirring tank 1, a liftable stirring device, a foam generating hood, an automatic scraper device, a scraper cleaning device, a froth tank 2, an overflow device, and a liquid level meter 3. The liftable stirring device can automatically control the lifting and lowering, strengthen the slurry disturbance in the stirring tank 1, and improve the mixing efficiency; the grid structure of the foam generating hood increases the contact area between the slurry and the air, and improves the foaming efficiency; the automatic scraper device can automatically adjust the height of the scraper device according to the liquid level in the stirring tank 1 detected by the liquid level meter 3, thereby avoiding waste of resources; the scraper cleaning device can clean the froth attached to the scraper 25, and improve the scraping efficiency.

[0039] The working principle of the utility model is as follows: when the ore pulp enters the stirring tank 1, the driving motor a4 is started, driving the shaft body 5 to rotate, transmitting power to the impeller device 6, and the impeller device 6 rotates to form a negative pressure in the middle area, and the air is sucked into the shaft body shell 31 from the air inlet 30 and then released from the air hole 32 to the middle of the impeller device 6. Due to the negative pressure operation, the ore pulp enters the middle of the impeller device 6 from the top and bottom of the impeller device 6 and mixes with the air. In this process, the hydraulic lifting platform 7 can automatically rise and fall, driving the rotating impeller device 6 to rise and fall in the stirring tank 1, thereby strengthening the disturbance of the ore pulp in the stirring tank 1 and improving the mixing efficiency of the ore pulp and air.

[0040] In the process of mixing slurry and air, the slurry enters through the guide bottom plate 9 below the impeller device 6. Under the disturbance of the impeller device 6, the air and the slurry are further mixed through the foaming side plate 8, generating a large number of bubbles. The bubbles are attached with mineral components to be separated and rise to the surface of the slurry to form foam. The annular grid structure on the foaming side plate 8 increases the contact area between the slurry and water. The circular guide holes provided on the guide bottom plate 9 improve the flow of the slurry below and improve the foaming efficiency.

[0041] A large amount of froth formed in the stirring tank 1 accumulates on the surface of the slurry. The telescopic cylinder on the pneumatic lifting platform 11 in the automatic scraper device automatically rises and falls according to the liquid level signal detected by the liquid level meter 3, thereby adjusting the height of the scraper from the liquid level to prevent the problem of reduced scraping efficiency when the height is too high and the slurry being carried out when the height is too low. After the pneumatic lifting platform 11 is adjusted to a suitable height, the driving motor b12 drives the scraper mechanism 13 to rotate, and the froth is scraped out by the rotating scraper and enters the froth tank 2 along the inclined body 29;

[0042] During the operation of the automatic scraper device, the drive motor c14 in the scraper cleaning device is started, and the drive motor c14 drives the front end shaft 19 and the rear end shaft 20 to rotate, thereby driving the crank 21 on the main journal 26 to rotate, and the main journal 26 on the crank 21 drives the connecting rod journal 27 connected to the crank 28 on both sides to rotate, and then the connecting rod journal 27 drives the connecting rod a22 to swing, and finally the connecting rod a22 drives the connecting rod b23 to do back and forth reciprocating motion in the slide frame 24, so that the cleaning scraper 25 installed on the slide frame 24 can scrape off the floating foam attached to the scraper, preventing the scraping foam from repeatedly sticking to the scraper, thereby improving the scraping efficiency;

[0043] In this process, the overflow device and the liquid level meter 3 work together to achieve stable slurry inlet and outlet flow rates and control the liquid level of the slurry in the stirring tank 1. The slurry in the stirring tank 1 enters the connecting pipe 34 below the liquid level meter 3 through the filter cover 33. The liquid level meter 3 detects the air pressure and converts it into a liquid level signal, thereby controlling the overflow valve group 16 to open and close to discharge the slurry from the overflow port to control the liquid level.

[0044] At this point, the entire phosphate ore flotation machine completes the flotation of the phosphate ore and transports the product to the next process.
