[0002] A flotation machine is short for a floating ore dressing machine, referring to the mechanical equipment that completes the flotation process. In the flotation machine, the pulp treated with reagents is agitated and aerated, so that some of the ore particles selectively adhere to the bubbles; they float to the surface of the pulp and are scraped out to form a foam product, and the rest remains in the pulp to achieve the purpose of separating minerals.

The end of the connecting rod 17 is fixedly connected to the side surface of the connecting plate 19. A limiting member is provided on the top surface of the connecting rod 17.

[0031] Further, as Figure 2 and Figure 3 shown, specifically, the limiting member includes two fixing blocks 16 fixedly provided on the bottom surface of the mounting plate 4. A limiting rod 24 is fixedly provided on one side of the fixing block 16. A movable seat 25 is fixedly provided on the top surface of the connecting rod 17. The limiting rod 24 movably penetrates through the movable seat 25.

[0032] It should be noted that the limiting rod 24 is rectangular. The movable seat 25 is limited by the limiting rod 24, so as to maintain the stability when the rectangular ring 15 and the connecting plate 19 move.

[0033] Further, as Figure 1 and Figure 2 shown, specifically, the driving assembly includes a driving motor 5 fixedly installed on the top surface of the mounting plate 4.

Four Z-shaped support blocks 27 distributed in a rectangle are fixedly provided on the outer surface of the collar 26. The Z-shaped support blocks 27 are fixedly connected to the mounting plate 4 by bolts.

[0035] It should be noted that the third gear 12, the fourth gear 13, the fifth gear 14 and the rack bar 22 are protected by the guard plate 3 to reduce the splashing of mortar; the first gear 8 and the second gear 10 are protected by the collar 26.

[0036] This solution has the following working process: The driving motor 5 drives the belt 7 to rotate, thereby driving the transmission shaft 9 inside the flotation column 2 to rotate, and then driving the impeller 28 to rotate at the bottom of the flotation tank 1. The impeller 28 rotates to generate a centrifugal force to form a negative pressure. On the one hand, sufficient air is inhaled and mixed with the pulp. On the other hand, the pulp is stirred and mixed with the drug, and at the same time, the foam is refined, so that the minerals adhere to the foam, float to the pulp surface to form mineralized foam, and then the foam is scraped out. When the transmission shaft 9 rotates, it drives the second gear 10 to rotate, thereby driving the first gear 8 to rotate, and then drives the third gear 12 to rotate through the rotating shaft 11, thereby driving the fourth gear 13 to rotate on the flotation column 2, and then driving the two fifth gears 14 and the connecting shaft 21 to rotate on the support block 23. Then the connecting shaft 21 drives the incomplete gear 20 to rotate. By meshing the incomplete gear 20 with one of the racks 22, the rectangular ring 15 is driven to move horizontally. Then, by meshing the incomplete gear 20 with the other rack 22, the rectangular ring 15 is reset, thereby realizing the horizontal reciprocating movement of the rectangular ring 15. Then, the connecting rod 17 drives the connecting plate 19 to move horizontally in a reciprocating manner, and then drives a plurality of stirring rods 18 to stir the edge of the inner wall of the flotation tank 1, thereby promoting the mixing between the medicament and the mortar and improving the flotation efficiency.

[0037] According to the above working process, it can be seen that: through the setting of the mixing mechanism, while the impeller 28 rotates at the bottom of the flotation tank 1, it drives a plurality of stirring rods 18 to move horizontally in a reciprocating manner, so as to stir the upper edge of the inner wall of the flotation tank 1, which is convenient for the mortar and the medicament at the edge of the flotation tank 1 to be more fully mixed, thereby improving the flotation efficiency. The connecting rod 17 is limited by the limiting member, so as to maintain the stability of the stirring rod 18 during horizontal movement.

[0038] The driving motor 5 can be purchased on the market. The driving motor 5 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed. Therefore, it will not be repeated in the specification.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in this application, and all should be covered by the protection scope of this application.
