[0019] like Figure 1 and Figure 2 As shown, as another preferred embodiment of the present invention, the inflation unit includes an air pump 10, an air delivery pipe 11 and a positioning ring 12; The air pump 10 is fixedly mounted on the top of the top shell 2, the positioning ring 12 is fixedly mounted on the bottom of the top shell 2, and the positioning ring 12 is rotatably connected to the stirring shaft 4.

[0020] In one embodiment of the present invention, the air pump 10 works to transport the gas along the air pipe 11 to the positioning ring 12, and enters the internal chamber through the hole set on the stirring shaft 4. The gas moves downward along the stirring shaft 4 and is transported into the liquid as the stirring rod 8 rotates, thereby improving the bubble effect.

[0021] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the overflow defoaming mechanism 200 includes a movable rod 13, a flow groove 14, a scraper 15, a toggle rod 16, a longitudinal groove 17 and an output pipe 18; The movable rod 13 is obliquely mounted on the stirring shaft 4, a flow groove 14 is provided on the side of the movable rod 13, and a scraper 15 is also installed at the bottom of the movable rod 13; A toggle rod 16 is fixedly mounted on the inner side of the top shell 2, and the toggle rod 16 contacts the movable rod 13 in the rotating state; The longitudinal groove 17 is disposed in the top shell 2 , and an output pipe 18 is installed at the bottom end of the longitudinal groove 17 .

[0022] In one embodiment of the present invention, the toggle rod 16 is made of rubber material so as to exert a knocking force when the movable rod 13 passes by, thereby ensuring smooth movement of the foam-containing particles.

[0023] When in use, the bubbles come into contact with and adhere to the fine particles in the mineral, and the bubbles drive the mineral particles to move upward under the action of buoyancy. When moving to the horizontal plane, the stirring shaft 4 drives the movable rod 13 and the scraper 15 to rotate, and the scraper 15 pushes the bubbles into the flow channel 14. The water-containing mineral particles move along the flow channel 14, and enter the longitudinal groove 17 when moving to the end, and finally enter the side box 19 along the output pipe 18.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the flow control ejection mechanism 300 includes a cam 21, a guide rod 22, an elastic support member 23, an elastic sleeve plate 24, a baffle 25 and a filter screen 26; The cam 21 is fixedly mounted on the bottom end of the stirring shaft 25, and the guide rod 22 is slidably mounted on the side box 19, one end of the guide rod 22 abuts against the cam 21, and an elastic support member 23 is sleeved on the guide rod 22; The filter screen 26 is fixedly installed inside the side box 19, and an elastic sleeve plate 24 is slidably installed on the filter screen 26. The elastic sleeve plate 24 is movably connected to the end of the guide rod 22. A baffle plate 25 is installed on the inner side of the side box 19 at the top of the elastic sleeve plate 24.

[0025] In one example of the present invention, when water-containing mineral particles enter the side box 19 and fall on the filter screen 26, the stirring shaft 25 rotates and drives the cam 21 to rotate synchronously. The cam 21 pushes the guide rod 22 to slide along the side box 19 during rotation. The elastic support member 23 is elastically deformed under force. The guide rod 22 pushes the elastic sleeve 24 to slide along the filter screen 26. Water flows through the filter screen 26 and is discharged from the drain pipe 27. When the mineral particles move to the top of the filter screen 26, they are discharged through the through hole 20.

[0026] like Figure 1 and Figure 6 As shown, as another preferred embodiment of the present invention, the conveying and drying mechanism 400 includes a bevel gear 1 28, a bevel gear 29, a connecting gear 2 30, a conveying roller 31 and a conveying belt 32; The bevel gear 1 28 is fixedly mounted on the bottom end of the stirring shaft 1 4, the bevel gear 1 28 is meshed with a bevel gear 2 29, a connecting gear 1 is mounted on the side of the bevel gear 29, connecting gear 2 30 is mounted on both sides of the connecting gear 1, a conveying roller 31 is arranged on the side of the connecting gear 2 30, and a conveying belt 32 is arranged on the conveying roller 31; The second bevel gear 29, the second connecting gear 30 and the conveying roller 31 are all rotatably connected to the external bracket, thereby ensuring stable transmission.

[0027] In one embodiment of the present invention, when the stirring shaft 4 rotates, the bevel gear 28 is driven to rotate. Since the bevel gear 28 is meshed with the bevel gear 29, the bevel gear 29 and the connecting gear 1 can be driven to rotate. The connecting gear 1 drives the connecting gear 2 30 on both sides to rotate, and then drives the conveyor belt 32 to rotate through the conveying roller 31, so as to transport the mineral particles falling on the conveyor belt 32 to the outside, and dry them when transporting them to the drying plate 33. When the dried mineral particles pass through the scraper 35, the scraper 35 scrapes the mineral particles and drops them into the external storage box, thereby completing the collection of the mineral particles.

[0028] In summary, after water, minerals, flotation agents, active agents, foaming agents, etc. are added to the bottom box 1, the external motor drives the stirring shaft 4 to rotate, the stirring shaft 4 drives the stirring rod 8 to rotate, the stirring shaft 4 drives the stirring shaft 2 5 to rotate through the driving gear 6 and the driven gear 7, the stirring shaft 2 5 drives the stirring rod 2 9 to rotate, the stirring rod 1 8 and the stirring rod 2 9 stir the water, minerals, flotation agents, active agents, foaming agents, etc., the air pump 10 works to transport the gas along the gas pipe 11 to the positioning ring 12, and enters the internal chamber through the hole set on the stirring shaft 4, and the gas moves along the stirring shaft 4. The shaft 4 moves downward, and as it rotates with the stirring rod 8, it delivers gas into the liquid. The bubbles come into contact with the fine particles in the mineral and adhere to them. The bubbles drive the mineral particles upward under the action of buoyancy. When it moves to the horizontal plane, the stirring shaft 4 drives the movable rod 13 and the scraper 15 to rotate. The scraper 15 pushes the bubbles into the flow channel 14. The water-containing mineral particles move along the flow channel 14 and enter the longitudinal groove 17 when they move to the end. Finally, they enter the side box 19 along the output pipe 18 and fall on the filter screen 26. When the stirring shaft 25 rotates, it drives the cam 21 to rotate synchronously. The cam 21 rotates synchronously. During the rotation, the guide rod 22 is pushed to slide along the side box 19, and the elastic support member 23 is elastically deformed by the force. The guide rod 22 pushes the elastic sleeve plate 24 to slide along the filter screen 26. The water flows through the filter screen 26 and is discharged from the drain pipe 27. When the mineral particles move to the top of the filter screen 26, they are discharged through the through hole 20. At the same time, the stirring shaft 14 drives the bevel gear 1 28 to rotate. Since the bevel gear 1 28 is meshed with the bevel gear 2 29, the bevel gear 2 29 and the connecting gear 1 can be driven to rotate. The connecting gear 1 drives the connecting gear 2 30 on both sides to rotate, and then drives the conveying roller 31 to drive ... The belt 32 rotates to convey the mineral particles falling on the conveyor belt 32 to the outside, and dries them when conveyed to the drying plate 33. When the dried mineral particles pass through the scraper 35, the arranged scraper 35 scrapes the mineral particles and drops them into an external storage box; this separation device can effectively increase the contact frequency between fine mineral particles and floating bubbles, ensure that more mineral particles float to the surface per unit time, thereby improving the separation efficiency of mineral particles, and at the same time, can avoid blockage during the separation rotation process, quickly remove the moisture contained in the mineral particles, and realize automatic transportation and collection.
