Description

Technical Field

[0001] The invention relates to the technical field of lepidolite flotation devices, in particular to an energy-saving lepidolite flotation device for mining. Background Art

[0002] Lepidolite, as an extremely important source of lithium in nature, plays an irreplaceable role in many key fields such as new energy technology, high-end electronic manufacturing, and glass and ceramic industry. The effective development and utilization of this mineral is of great significance to promoting scientific and technological progress and promoting industrial upgrading. Therefore, in its flotation process, the crushing of the raw ore is not only directly related to the subsequent separation and purification efficiency of lithium elements, but also has a profound impact on the overall utilization efficiency of resources and the realization of energy conservation and emission reduction goals. The quality and efficiency of the crushing process are directly related to the quality and production cost of the final product, and are a key link that cannot be ignored in the processing of lepidolite.

[0003] However, the traditional lepidolite crushing mainly relies on beating and squeezing. Although this crushing method is easy to operate, its high energy consumption problem is becoming increasingly prominent.

The present invention significantly reduces the energy consumed in crushing lithium mica ore by setting the synergistic effect of the crushing component and the resonance auxiliary component, thereby achieving energy saving. The crushing motor drives the hollow shaft to rotate, driving the crushing rod and crushing teeth to mechanically crush the ore; at the same time, the high-frequency vibration wave generated by the vibration generator achieves efficient energy focusing and amplification through the special cylindrical barrel design of the resonance cylinder, and is transmitted to the crushing teeth, so that it produces a strong resonance effect with the lithium mica ore, thereby achieving ore crushing under relatively small external force, greatly reducing energy consumption.

[0049] See also Figure 1-12 An energy-saving lithium mica flotation device for mining includes a flotation box 1 and a mounting frame 2 fixedly mounted on the top of the flotation box 1, and a crushing mechanism 3 is arranged on the mounting frame 2. The crushing mechanism 3 includes a crushing component 31 and a resonance auxiliary component 32. Among them, the crushing component 31 is used to directly crush the lithium mica ore by mechanical means. The resonance auxiliary component 32 is used to use high-frequency vibration waves to produce a resonance effect with the ore to weaken the internal binding force of the ore. Through the synergistic effect of the crushing component 31 and the resonance auxiliary component 32, the crushing efficiency is improved, the energy consumption is reduced, and the efficient and energy-saving crushing of the lithium mica ore is achieved.

[0050] See also Figure 1-12Structural schematic diagram, the crushing assembly 31 includes a crushing box 311 fixedly mounted on the mounting frame 2, the inner cavity of the crushing box 311 is rotatably connected with a hollow shaft 312, the outer circumferential surface of the hollow shaft 312 is fixedly mounted with a plurality of hollow shaft discs 315, the outer circumferential surface of the hollow shaft disc 315 is fixedly mounted with a plurality of crushing rods 316 connected with the inner cavity of the hollow shaft disc 315, and the outer side of the crushing rod 316 is fixedly mounted with a plurality of crushing teeth 317. The crushing assembly 31 also includes a crushing motor bracket 318 fixedly mounted on the crushing box 311, a crushing motor 319 is installed in the crushing motor bracket 318, the output end of the crushing motor 319 is fixedly connected with a driving gear 314, the outer side of the driving gear 314 is meshed with a driven gear 313, and the driven gear 313 is sleeved with one end of the hollow shaft 312 that passes through the crushing box 311.

[0051] When the crushing assembly 31 is crushing, the crushing motor 319 is started, and the crushing motor 319 drives the driving gear 314 to rotate. When the driving gear 314 rotates, it drives the driven gear 313 meshing with it to rotate. When the driven gear 313 rotates, it drives the hollow shaft 312 to rotate. When the hollow shaft 312 rotates, it drives the hollow shaft disc 315, the crushing rod 316 and the crushing teeth 317 on the hollow shaft 312 to rotate. When the crushing rod 316 and the crushing teeth 317 rotate, the lithium mica ore inside the crushing box 311 is mechanically crushed.

[0052] See also Figure 2-4 and Figure 7-8 Structural diagram, the resonance auxiliary component 32 includes a plurality of conductive rods 321 fixedly mounted on the inner circumference of the crushing box 311, the plurality of conductive rods 321 are enclosed in a cylindrical shape adapted to the crushing box 311, and a resonance tube 322 is fixedly mounted on the inner side of the plurality of conductive rods 321, and a conductive main ring 323 is fixedly mounted on one end of the conductive rod 321 penetrating the crushing box 311, and a plurality of connecting rods 324 are fixedly mounted on the inner circumference of the conductive main ring 323, and a connector 325 is fixedly mounted on one end of the connecting rod 324 away from the conductive main ring 323. The resonance auxiliary component 32 also includes a vibration generator mounting bracket 326 fixedly mounted on the crushing box 311, a vibration generator 327 is fixedly mounted on the inner side of the vibration generator mounting bracket 326, and the output end of the vibration generator 327 is fixedly connected to the connector 325.

[0053] While the crushing component 31 is crushing, the resonance auxiliary component 32 uses high-frequency vibration waves to produce a resonance effect with the ore to weaken the internal binding force of the ore. The specific process is as follows: when the vibration generator 327 is started, the generated high-frequency vibration waves are transmitted to the conductive main ring 323 through the connector 325 and the connecting support rod 324, and are evenly dispersed to the conductive rod 321. The cylindrical barrel-shaped resonance tube 322 made of a high elastic modulus and low acoustic impedance alloy material fixed on the inner surface of the conductive rod 321 focuses and amplifies the vibration waves, and then transmits them to the crushing teeth 317, generating a resonance effect with the lithium mica ore, assisting the mechanical crushing process, significantly improving the crushing efficiency and reducing energy consumption.

[0054] In the above embodiment, the crushing box 311 is a cylindrical box. The mounting frame 2 is composed of a plurality of mounting rods, and the upper area of ​​the mounting frame 2 forms a semi-cylindrical groove adapted to the crushing box 311 so as to place the crushing box 311.

[0055] The middle parts of the two planes of the crushing box 311 can be provided with perforations. The hollow shaft 312 can be inserted into the crushing box 311 through the perforations, and the middle part of the hollow shaft 312 can be located in the inner cavity of the crushing box 311, and the two ends of the hollow shaft 312 can be movably inserted into the perforations.

[0056] In some embodiments, the crushing rod 316 and the crushing teeth 317 are both made of light and high-strength carbon fiber material. Among them, the crushing teeth 317 are designed with bionic teeth.

[0057] In this embodiment, the crushing rod 316 and the crushing teeth 317 are made of light and high-strength carbon fiber materials, which not only reduces the weight of the components and reduces energy consumption, but also ensures sufficient crushing strength. During the crushing process of the crushing teeth 317, the bionic design of the crushing teeth 317 increases the pressure of the single point contact with the ore, making the crushing more efficient.

[0058] In some embodiments, the conductive rod 321 , the conductive main ring 323 and the connecting support rod 324 are made of high-strength, low-damping maraging steel.

[0059] In this embodiment, since low-damping maraging steel is usually composed of iron, a high proportion of nickel (18% to 25%), cobalt, molybdenum, titanium and other elements, these alloy elements form intermetallic compounds during the aging process, thereby improving the strength of the steel, and improving the strength of the conductive rod 321, the conductive main ring 323 and the connecting support rod 324. In addition, since low-damping maraging steel can reduce the loss of vibration wave energy and the impact on vibration, therefore, when the conductive rod 321, the conductive main ring 323 and the connecting support rod 324 are all made of low-damping maraging steel, it can facilitate the efficient and stable transmission of vibration waves to the resonance tube 322, improve the resonance-assisted crushing effect, and further optimize the energy-saving performance.

[0060] In some embodiments, the resonance tube 322 is made of an alloy material with high elastic modulus and low acoustic impedance. The resonance tube 322 is in the shape of a cylindrical barrel, wherein a layer of nano-scale sound-absorbing coating is distributed on the outer surface of the resonance tube 322.

[0061] In this embodiment, since the alloy material with high elastic modulus can make the vibration wave propagate faster, and the alloy material with low acoustic impedance can reduce the reflection and transmission loss of the wave, when the resonance cylinder 322 is made of the alloy material with high elastic modulus and low acoustic impedance, it can facilitate the vibration wave to be transmitted to the inside of the ore quickly and efficiently, weaken the internal bonding force of the ore, further reduce energy consumption, and optimize the crushing effect.

[0062] In addition, since the nano-scale sound-absorbing coating can cause the vibration wave to undergo specific reflection and scattering on the coating surface, thereby changing the propagation direction and energy distribution of the vibration wave, a layer of nano-scale sound-absorbing coating is distributed on the outer cylindrical surface of the resonance cylinder 322 to facilitate the reflection and scattering of the vibration wave to the lithium mica ore in different parts, thereby weakening the internal binding force of the lithium mica ore in different parts.

[0063] The resonance tube 322 may be made of a specific alloy, such as Phynox alloy.

[0064] In some embodiments, the vibration generator 327 is made of piezoelectric ceramic material.

[0065] In this embodiment, the vibration generator 327 is made of piezoelectric ceramic material. Its unique piezoelectric effect can efficiently convert electrical energy into mechanical vibration energy, generate stable high-frequency vibration waves, and enhance the resonance-assisted crushing effect.

[0066] Based on the above embodiments, in some embodiments, a covered feed bin 3111 communicating with the inner cavity of the crushing box 311 is fixedly installed on the top of the crushing box 311. A filter screen 3112 is bolted to the bottom of the crushing box 311, and a material blocking plate 3113 located directly below the filter screen 3112 is slidably connected to the filter screen 3112.

[0067] In this embodiment, the covered feed bin 3111 is convenient for adding ore. After the ore is crushed by the crushing assembly 31 and the resonance-assisted crushing, it falls into the filter 3112. The filter 3112 screens the ore according to the volume to ensure that the qualified ore passes through. The baffle plate 3113 is located directly below the filter 3112, and its shape fits tightly. If the baffle plate 3113 is not pulled out, the qualified ore cannot fall into the flotation box 1. The operator pulls out the baffle plate 3113 in time, and the qualified ore is discharged from the filter opening to the flotation box for subsequent operations. In this way, it can be ensured that only the ore that meets the standard enters the flotation box, and the unqualified ones remain in the crushing box 311 for further crushing.

[0068] See also Figure 1 , Figure 4-5 , Figure 7 , Figure 9-12 Structural schematic diagram, the crushing mechanism 3 also includes a dust reduction component 33, the dust reduction component 33 includes a dust reduction branch pipe 331 fixedly installed on the hollow shaft disk 315, the inner cavity of the crushing rod 316 and connected with the inner cavity of the hollow shaft rod 312, a plurality of atomizing nozzles 332 penetrating the crushing rod 316 are fixedly installed on the outer circumference of the dust reduction branch pipe 331, and a grid protection net 333 is fixedly installed on the output end of the atomizing nozzle 332 and located on the crushing rod 316, a rotary joint 334 connected with the inner cavity of the hollow shaft rod 312 is fixedly installed at one end of the hollow shaft rod 312 close to the driven gear 313, and a dust reduction main pipe 335 is fixedly installed at one end of the rotary joint 334 away from the hollow shaft rod 312, a micro water pump 336 is fixedly installed at the liquid inlet end of the dust reduction main pipe 335, and a bio-nanofilm preparation containing box 337 fixedly connected to the crushing box 311 is fixedly installed at the liquid inlet end of the micro water pump 336.

[0069] The dust reduction component 33 extracts the bio-nanofilm preparation in the bio-nanofilm preparation storage box 337 through the micro water pump 336, enters the hollow shaft 312 through the dust reduction main pipe 335 and the rotary joint 334, and then is diverted to the dust reduction branch pipe 331, and finally sprayed out by the atomizing nozzle 332 to form a mist-like bio-nanofilm preparation. The preparation is evenly sprayed on the surface of the lithium mica ore rotating with the crushing rod 316 under the protection of the grid protection net 333, forming an extremely thin nano-level protective film. The function of this dust reduction component 33 is to use the viscosity and adsorption of the bio-nanofilm preparation to effectively adsorb and agglomerate the dust particles generated during the crushing process to form larger particle clusters, thereby inhibiting the flying and diffusion of dust, significantly improving the working environment, and reducing the pollution of dust to the surrounding environment, meeting environmental protection requirements. Specifically, the bio-nanofilm can maximize the extension of water molecules and adsorb fine dust particles, thereby exerting a dust removal effect.

[0070] In some embodiments, the mesh protection net 333 is made of stainless steel, wherein the mesh protection net 333 and the crushing rod 316 are on the same horizontal plane.

[0071] In this embodiment, the mesh protection net 333 is used to protect the nozzle from damage. At the same time, with the cooperation of the rotating joint 334, it ensures that the agent is rotated and sprayed evenly, effectively suppresses dust flying, provides a good working environment, and realizes environmentally friendly crushing operations.

[0072] See also Figure 1-2 Structural schematic diagram, a cross bar 4 is threadedly installed on the top of the flotation box 1, a stirring motor 5 is fixedly installed on the top of the cross bar 4, the output end of the stirring motor 5 passes through the cross bar 4 and is fixedly installed with a stirring member 6; the stirring member 6 is composed of a stirring rod and a stirring blade, wherein the stirring blade is overall in the shape of a fish fin.

[0073] During operation, the stirring motor 5 drives the stirring element 6 to rotate at a high speed. The fish-fin-shaped stirring blades form an efficient and smooth stirring action in the water by virtue of their unique shape, so that the lithium mica ore can be fully and evenly dispersed in the water. This design not only significantly improves the flotation efficiency, but also effectively reduces the energy loss in the stirring process by virtue of the low resistance characteristics of the fish-fin-shaped stirring blades, thereby playing a key role in energy saving and efficiency improvement in the entire lithium mica flotation process.

[0074] See also Figure 1-2 Structural schematic diagram: the inner cavity of the flotation box 1 is rotatably connected with a scraper plate 7 that penetrates the flotation box 1 , and one end of the scraper plate 7 is fixedly mounted with a scraper motor 8 that is fixedly connected to the outer side of the flotation box 1 .

[0075] During the flotation stage of lithium mica ore, the scraper motor 8 is started to drive the scraper plate 7 to rotate in the inner cavity of the flotation box 1. The design of the scraper plate 7 enables it to effectively scrape or push the foam layer rich in lithium mica on the inner surface of the flotation box 1. These foam layers are formed by bubble adhesion by utilizing the surface property difference between lithium mica and other impurities after adding an appropriate amount of flotation reagent and properly supplementing gas. The automatic scraping action of the scraper plate 7 reduces manual operation, allowing the flotation process to proceed continuously and stably, thereby improving the overall production efficiency; the movement of the scraper plate 7 can ensure that the foam layer rich in lithium mica is scraped out or overflows in a timely and effective manner, and then high-quality lithium mica flotation products are collected, providing a good foundation for subsequent dehydration, drying and purification treatment.

[0076] When used specifically, the working principle of the present invention is as follows:

[0077] When using the energy-saving lithium mica flotation device for mining, the lithium mica ore to be crushed is first added into the crushing box 311 through the covered feed bin 3111. Then, the crushing component 31, the resonance auxiliary component 32, and the dust reduction component 33 are started to collaboratively complete the crushing of the ore, the resonance auxiliary crushing and the dust reduction operations.

[0078] Specifically, after the crushing motor 319 is started, it drives the driving gear 314 to rotate, thereby driving the meshing driven gear 313 and the connected hollow shaft 312 to rotate. The hollow shaft disc 315, the crushing rod 316 and the crushing teeth 317 on the hollow shaft 312 rotate accordingly, and the lepidolite ore is mechanically crushed.

[0079] At the same time, the vibration generator 327 in the resonance auxiliary component 32 starts to work, generating high-frequency vibration waves. These vibration waves are transmitted to the conductive main ring 323 through the connecting rod 324, and are further evenly dispersed to the conductive rod 321. Since the conductive rod 321 is distributed in a mesh shape on the outside of the resonance cylinder 322, the vibration waves can be effectively transmitted to the resonance cylinder 322. The resonance cylinder 322 achieves efficient focusing and amplification of energy. This amplified vibration energy is then transmitted to the crushing teeth 317, causing it to produce a strong resonance effect with the lithium mica ore. In addition, the nano-scale sound-absorbing coating on the inner circular surface of the resonance cylinder 322 can absorb and suppress unnecessary clutter and noise, further improving the purity and efficiency of the resonance.

[0080] When the resonance frequency is close to the natural frequency of the ore, the intermolecular forces inside the ore are significantly weakened, thereby generating a large number of evenly distributed tiny cracks. At this time, the crushing teeth 317 can crush the ore along these cracks under the action of a relatively small external force.

[0081] During crushing, the micro water pump 336 starts working synchronously. The micro water pump 336 will extract the bionanofilm preparation inside the bionanofilm preparation storage box 337 and transport it to the hollow shaft 312 through the dust reduction main pipe 335. After the bionanofilm preparation enters the hollow shaft 312, it will be diverted into the dust reduction branch pipe 331 and sprayed out through the atomizing nozzle 332 on the dust reduction branch pipe 331. The grid protection net 333 can prevent the lithium mica ore from damaging the atomizing nozzle 332 during the crushing process.

[0082] Under the rotation of the crushing motor 319 and the rotary joint 334, the biological nanofilm preparation is evenly sprayed on the surface of the lithium mica ore to form an extremely thin nano-level protective film. This film has strong viscosity and adsorption. When dust is generated during the crushing of the lithium mica ore, the dust particles will be adsorbed by the nanofilm and agglomerated together to form larger particle clusters, thereby effectively inhibiting the flying and diffusion of dust, effectively improving the working environment, and also reducing the pollution of dust to the surrounding environment, meeting environmental protection requirements.

[0083] After crushing, the baffle plate 3113 is pulled outward, and the lepidolite ore that meets the standard falls into the flotation box 1 through the filter screen 3112, while the lepidolite ore that does not meet the standard remains in the crushing box 311 to be crushed again. In the flotation box 1, the stirring motor 5 is started, and the lepidolite ore is fully stirred by the stirring member 6 to be dispersed in the water.

[0084] Subsequently, an appropriate amount of flotation reagent is added, and an air pump is used to supplement gas into the solution. The difference in surface properties between lepidolite and other impurities is utilized to achieve flotation separation of lepidolite through bubble attachment. During the flotation process, the foam scraping motor 8 is started, and the foam layer rich in lepidolite is scraped out or overflowed by the foam scraping plate 7 to collect the flotation product of lepidolite. Finally, the collected lepidolite flotation product is further dehydrated, dried and purified to meet production requirements.

[0085] In summary, this device realizes efficient, energy-saving and environmentally friendly crushing and flotation operations of lithium mica ore by combining mechanical crushing, resonance-assisted crushing and dust reduction technology, and significantly improves resource utilization efficiency and production benefits.

[0086] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
