Description

Technical Field

[0001] This invention belongs to the field of mineral flotation technology, and particularly relates to a device for separating fine mineral particles. Background Technology

[0002] As my country's industrialization deepens, the utilization rate of mineral resources as raw materials is also increasing. However, the deterioration of geological conditions, indiscriminate mining, and decline of advantageous resources have led to a sharp increase in the proportion of fine-grained flotation, which continues to worsen. This has made the contradictions in mineral flotation more prominent. Therefore, it is imperative to develop efficient mineral flotation equipment. Mineral beneficiation usually involves adding flotation agents to the suspension of mineral particles before flotation.

[0003] The flotation devices currently in use perform two-stage flotation using a double-barrel design. Both barrels are equipped with overflow channels to allow mineral foam that has been raised by compressed air to enter the corresponding overflow channels and be discharged from the corresponding discharge ports. However, there is a problem with the low frequency of contact between mineral particles and foam, which means that more mineral particles cannot be raised within a certain time, affecting the separation efficiency. Furthermore, the separation process is prone to clogging and cannot quickly remove moisture from the surface of the minerals. Summary of the Invention

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0041] like Figures 1-6The diagram shows a structural representation of a fine mineral particle separation device according to an embodiment of the present invention. The device includes a bottom chamber 1, a top shell 2, a synchronous stirring mechanism 100, an aeration unit, an overflow defoaming mechanism 200, a side chamber 19, a flow-controlled ejection mechanism 300, and a conveying and drying mechanism 400. The top shell 2 is located outside the bottom chamber 1, and a feed hopper 3 is mounted on the top of the top shell 2. The synchronous stirring mechanism 100 is rotatably mounted on the bottom chamber 1 and the top shell 2, mixing the minerals, water, and flotation reagents entering the bottom chamber 1. The aeration unit is mounted on the top shell 2 and injects gas into the liquid during the rotation of the synchronous stirring mechanism 100. The overflow defoaming mechanism 200 is fixedly mounted outside the stirring shaft 4 in the synchronous stirring mechanism 100, and its free end is slidably connected to the inner wall of the top shell 2. The side chamber 19... Symmetrically arranged on the sides of the base box 1, the side box 19 has through holes 20 and a drain pipe 27 installed at the bottom of the side box 19. The output pipe 18 of the overflow defoaming mechanism 200 extends into the side box 19. The flow control ejection mechanism 300 is installed on the side box 19, and one end of the flow control ejection mechanism 300 is connected to the synchronous stirring mechanism 100. The conveying and drying mechanism 400 is arranged at the bottom of the flow control ejection mechanism 300. A drying plate 33 is provided on the inner side of the conveying and drying mechanism 400 to dry the mineral particles discharged from the side box 19 during transportation. A fixing rod 34 is also installed on the outer side of the side box 19. A scraper 35 is fixedly connected to the bottom end of the fixing rod 34. The scraper 35 abuts against the conveyor belt 32 in the conveying and drying mechanism 400 to scrape off the dried mineral particles and collect them with an external collection box.

[0042] like Figure 1 As shown, in a preferred embodiment of the present invention, the synchronous stirring mechanism 100 includes a stirring shaft 4, a stirring shaft 5, a drive gear 6, a driven gear 7, a stirring rod 8, and a stirring rod 9.

[0043] The stirring shaft 4 is rotatably mounted on the bottom box 1 and the top shell 2. Multiple stirring shafts 5 are provided. All stirring shafts 5 are mounted on the bottom of the bottom box 1. A drive gear 6 is installed on the bottom of the stirring shaft 4, and a driven gear 7 is installed on the bottom of the stirring shaft 5. The drive gear 6 and the driven gear 7 are in a meshing state.

[0044] Multiple stirring rods 8 are fixedly installed on the stirring shaft 4, and multiple stirring rods 9 are fixedly installed on the stirring shaft 5. The stirring rods 8 and 9 work together.

[0045] In one embodiment of the present invention, the stirring shaft 4 is driven by an external motor. When the motor rotates, it drives the stirring shaft 4 to rotate along the bottom box 1 and the top shell 2. The drive gear 6 rotates synchronously. Since the drive gear 6 meshes with the driven gear 7, it can drive the stirring shafts 5 on both sides to rotate synchronously. The stirring shaft 4 drives the stirring rod 8 to rotate, and the stirring shaft 5 drives the stirring rod 9 to rotate. The stirring rod 8 and the stirring rod 9 stir the incoming water, minerals, flotation reagents, activators, foaming agents, etc.

[0046] like Figure 1 and Figure 2 As shown, in another preferred embodiment of the present invention, the inflation unit includes an air pump 10, an air supply pipe 11, and a positioning ring 12;

[0047] The air pump 10 is fixedly installed on the top of the top shell 2, and the positioning ring 12 is fixedly installed on the bottom of the top shell 2. The positioning ring 12 is rotatably connected to the stirring shaft 4. The stirring shaft 4 has a hollow structure inside. Multiple holes are opened on the stirring shaft 4 at the position corresponding to the positioning ring 12. The positioning ring 12 is connected to the air pump 10 through the air supply pipe 11.

[0048] The stirring rod 8 has a flow channel inside, which is connected to the interior of the stirring shaft 4, and the stirring rod 8 also has multiple vent holes.

[0049] In one embodiment of the present invention, the air pump 10 operates to deliver gas along the gas delivery pipe 11 to the positioning ring 12, and enters the internal chamber through the hole provided on the stirring shaft 4. The gas moves downward along the stirring shaft 4 and is delivered into the liquid as it rotates with the stirring rod 8, thereby improving the bubble effect.

[0050] like Figure 1 and Figure 3 As shown, in another preferred embodiment of the present invention, the overflow defoaming mechanism 200 includes a movable rod 13, a flow channel 14, a scraper 15, a toggle rod 16, a longitudinal groove 17, and an output pipe 18.

[0051] 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.

[0052] A lever 16 is fixedly installed on the inner side of the top shell 2, and the lever 16 contacts the movable rod 13 in the rotating state;

[0053] The longitudinal groove 17 is disposed inside the top shell 2, and an output pipe 18 is installed at the bottom end of the longitudinal groove 17.

[0054] In one embodiment of the invention, the actuating lever 16 is made of rubber material to apply a striking force when the movable lever 13 passes by, ensuring the smooth movement of the foam particles.

[0055] During use, the bubbles come into contact with and adhere to the fine particles in the minerals. Under the action of buoyancy, the bubbles drive the mineral particles to move upward. When they move to the horizontal plane, the stirring shaft 4 drives the movable rod 13 and the scraper 15 to rotate. The scraper 15 lifts the bubbles into the flow channel 14. The water-containing mineral particles move along the flow channel 14 and enter the longitudinal channel 17 when they reach the end. Finally, they enter the side box 19 along the output pipe 18.

[0056] like Figure 1 , Figure 4 and Figure 5 As shown, in 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 24, a baffle 25, and a filter screen 26.

[0057] The cam 21 is fixedly installed at the bottom end of the stirring shaft 5, and the guide rod 22 is slidably installed on the side box 19. One end of the guide rod 22 abuts against the cam 21, and an elastic support 23 is sleeved on the guide rod 22.

[0058] The filter screen 26 is fixedly installed inside the side box 19. An elastic sleeve 24 is slidably installed on the filter screen 26. The elastic sleeve 24 is movably connected to the end of the guide rod 22. A baffle 25 is installed on the inner side of the side box 19 at the top of the elastic sleeve 24.

[0059] In one embodiment of the present invention, when water-containing mineral particles enter the side box 19 and fall onto the filter screen 26, the stirring shaft 25 rotates, causing the cam 21 to rotate synchronously. During rotation, the cam 21 pushes the guide rod 22 to slide along the side box 19. The elastic support member 23 undergoes elastic deformation 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 outward from the drain pipe 27. When the mineral particles move to the top of the filter screen 26, they pass through the through hole 20 and are discharged outward.

[0060] like Figure 1 and Figure 6 As shown, in another preferred embodiment of the present invention, the conveying and drying mechanism 400 includes a first bevel gear 28, a second bevel gear 29, a second connecting gear 30, a conveying roller 31, and a conveyor belt 32;

[0061] The first bevel gear 28 is fixedly installed at the bottom end of the first stirring shaft 4. The second bevel gear 29 meshes with the first bevel gear 28. The first connecting gear 29 is installed on the side of the second bevel gear 29. The second connecting gear 20 is installed on both sides of the first connecting gear. The second connecting gear 20 is arranged on the side of the second connecting gear 20. The conveyor roller 31 is arranged on the conveyor roller 31. The conveyor belt 32 is arranged on the conveyor roller 31.

[0062] The bevel gear 29, the connecting gear 30, and the conveying roller 31 are all rotatably connected to the external bracket, thereby ensuring stable transmission.

[0063] In one embodiment of the present invention, when the stirring shaft 4 rotates, it drives the bevel gear 28 to rotate. Since the bevel gear 28 meshes with the bevel gear 29, it can drive the bevel gear 29 and the connecting gear 1 to rotate. The connecting gear 1 drives the connecting gears 20 on both sides to rotate, which in turn drives the conveyor belt 32 to rotate through the conveyor roller 31, thereby conveying the mineral particles that fall onto the conveyor belt 32 and drying them when they are conveyed to the drying plate 33. When the dried mineral particles pass through the scraper 35, the scraper 35 scrapes the mineral particles off and they fall into the external collection box, thus completing the collection of mineral particles.

[0064] In summary, after water, minerals, flotation reagents, activators, frothers, etc. are added to the bottom tank 1, the external motor drives the stirring shaft 4 to rotate, which in turn drives the stirring rod 8 to rotate. The stirring shaft 4, through the drive gear 6 and driven gear 7, drives the stirring shaft 5 to rotate, which in turn drives the stirring rod 9 to rotate. The stirring rods 8 and 9 stir the water, minerals, flotation reagents, activators, frothers, etc. The air pump 10 operates to deliver gas along the gas supply pipe 11 to the positioning ring 12, and then through the holes on the stirring shaft 4 into the internal chamber. The gas then moves along the stirring shaft 4... Shaft 4 moves downwards and, as it rotates with stirring rod 8, delivers gas into the liquid. The bubbles contact and adhere to the fine particles in the minerals. Under buoyancy, the bubbles carry the mineral particles upwards. When they reach the horizontal plane, stirring shaft 4 drives movable rod 13 and scraper 15 to rotate. Scraper 15 lifts the bubbles into flow channel 14. The water-containing mineral particles move along flow channel 14 and, at the end, enter longitudinal channel 17. Finally, they flow along output pipe 18 into side box 19 and fall onto filter screen 26. When stirring shaft 5 rotates, it drives cam 21 to rotate synchronously. 1. During rotation, the guide rod 22 slides along the side box 19, and the elastic support 23 undergoes elastic deformation 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 outward from the drain pipe 27. When the mineral particles move to the top of the filter screen 26, they pass through the through hole 20 and are discharged outward. At the same time, the stirring shaft 4 drives the bevel gear 28 to rotate. Since the bevel gear 28 meshes with the bevel gear 29, it can drive the bevel gear 29 and the connecting gear 1 to rotate. The connecting gear 1 drives the connecting gears 20 on both sides to rotate, which in turn drives the conveyor roller 31 to drive the conveyor. The conveyor belt 32 rotates to transport the mineral particles that fall onto it. These particles are then dried on the drying plate 33. After drying, the mineral particles are scraped off by the scraper 35 and fall into an external collection box. This separation device effectively increases the contact frequency between fine mineral particles and floating air bubbles, ensuring that more mineral particles float to the surface per unit time, thereby improving the separation efficiency. Simultaneously, it avoids clogging during the separation rotation process, quickly removes moisture from the mineral particles, and achieves automatic conveying and collection.
