Description

Technical Field

[0001] This invention relates to the field of mineral processing equipment technology, specifically to an adaptive adjustable flotation and cleaning device for minerals. Background Technology

[0002] Flotation is the mainstream separation process in the field of mineral processing. The flotation cleaning process directly determines the concentrate quality and overall recovery rate of valuable minerals. It is widely used in the purification and processing of various non-ferrous metals and non-metallic minerals. The flotation device mainly relies on the stirring mechanism to disturb the slurry and the air pump to generate bubbles, so that the target minerals attach to the bubbles and float to the surface, thereby achieving the separation of minerals from gangue. The stirring speed and aeration status are the core factors affecting the separation effect.

[0003] In actual mining production, the feed ore particles vary in size, and there are a large number of high-density valuable minerals and coarse-grained ores. These minerals themselves settle quickly, and the fixed-angle agitator plate cannot provide sufficient bottom disturbance force, which easily leads to the accumulation and sedimentation of high-density valuable minerals and coarse-grained ores at the bottom of the flotation cell. The mineral particles accumulated at the bottom of the cell cannot fully contact the air bubbles and automatically sprayed foaming agent in the cell, and cannot participate in the normal flotation separation reaction. This not only causes a large waste of valuable mineral resources and significantly reduces the mineral flotation recovery rate, but also causes long-term accumulation and blockage of the bottom space of the cell, affecting the normal circulation of the slurry. If the stirring speed is directly increased to solve the sedimentation problem, it will cause excessive turbulence in the slurry, which will roll the useless gangue at the bottom to the upper foam, reduce the purity of the concentrate, and increase the energy consumption of the equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adaptive adjustable mineral flotation and cleaning device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adaptive adjustable mineral flotation and cleaning device, comprising a housing, a feed trough mounted on the housing, a servo motor mounted on the housing, a pulley assembly mounted on the output end of the servo motor, and a rotating shaft mounted on the pulley assembly. The servo motor is equipped with a controller for adjusting its output power. The adaptive adjustable mineral flotation and cleaning device further includes: A stirring mechanism, mounted on the housing, is used to generate foam inside the housing to bind the minerals with the foam. An anti-sinking mechanism, installed on the outer casing, is used to prevent minerals from sinking to the bottom and improve the flotation effect of minerals.

[0006] The stirring mechanism includes a stirring plate mounted on the rotating shaft, a connecting pipe mounted on the outer casing, and an air inlet pipe mounted on the connecting pipe. The stirring plate is used to stir the liquid to generate bubbles, and the air inlet pipe is used to inject air to assist in generating bubbles. The anti-sinking mechanism includes a second servo motor mounted on the outer casing, a reciprocating lead screw mounted on the output end of the second servo motor, a second pulley assembly mounted on the reciprocating lead screw, a rotating rod mounted on the second pulley assembly, a deflector plate mounted on the rotating rod, a moving plate mounted on the reciprocating lead screw, an anti-sinking plate mounted on the moving plate, a long plate mounted on the outer casing, a spiral plate mounted on the moving plate, and a first transmission wheel mounted on the spiral plate. The deflector plate is used to push out foam.

[0007] The transmission wheel is rotatably connected to the long plate, the anti-sinking plate is rotatably connected to the outer shell, the reciprocating screw is rotatably connected to the outer shell, the rotating rod is rotatably connected to the outer shell, and the rotating shaft is rotatably connected to the outer shell.

[0008] The anti-sinking mechanism includes a disturbance mechanism installed on the anti-sinking plate. The disturbance mechanism includes a fixed frame installed on the anti-sinking plate, a rotating rod installed on the fixed frame, a foaming plate installed on the fixed frame, a push plate installed on the rotating rod, and a transmission wheel installed on the rotating rod. The foaming plate is used to improve foaming efficiency.

[0009] The disturbance mechanism also includes a filter plate installed on the connecting pipe, an elastic telescopic rod installed on the filter plate, a dredging plate installed on the telescopic end of the elastic telescopic rod, an elastic telescopic rod installed on the filter plate, and a protrusion ring installed on the rotating shaft. The filter plate is used to intercept the mineral liquid.

[0010] A spring is provided between the fixing frame and the foam board, the pushing plate is in contact with the foam board, the transmission wheel is in contact with the long plate, and the protrusion ring is in contact with the elastic telescopic rod.

[0011] The anti-sinking mechanism also includes an adjustment mechanism mounted on the movable plate. The adjustment mechanism includes a storage box mounted on the outer shell, a sliding rod mounted on the storage box, a lifting frame mounted on the sliding rod, a force-applying rod mounted on the movable plate, a pressure plate mounted on the sliding rod, and a spray plate mounted on the outer shell via a pipe.

[0012] The adjustment mechanism also includes a fixed plate mounted on the rotating rod, an L-shaped plate mounted on the actuating plate, and a limiting rod mounted on the L-shaped plate by a spring. The fixed plate is used to limit the limiting rod.

[0013] A spring is provided between the storage box and the lifting frame, the limiting rod is in contact with the fixing plate, and the force-applying rod is in contact with the lifting frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, during the flotation process, the rotation of the stirring plate disturbs the slurry inside the shell, ensuring that mineral particles of different sizes are uniformly suspended in the slurry. This prevents high-density useful minerals and coarse-grained ores from accumulating at the bottom of the tank, ensuring that all mineral particles can participate in the flotation reaction and reducing resource loss. Simultaneously, an air pump delivers air into the slurry. The initially formed bubbles are large and easily aggregate to rise quickly. The rotation of the stirring plate continuously cuts and disperses the rising airflow and bubbles, breaking down large bubbles into smaller ones, preventing localized gas accumulation, creating favorable conditions for mineral adsorption, and improving the adsorption effect. Furthermore, the output power of the servo motor can be dynamically adjusted according to operating conditions such as ore particle size, slurry concentration, mineral floatability, and incoming material load. For coarse-grained ores, the rotation speed is increased to prevent minerals from settling to the bottom; for fine-grained ores, the rotation speed is decreased to prevent gangue from being stirred into the foam, thus improving concentrate quality. Combined with air pump aeration, the size and distribution of bubbles are altered, extending bubble residence time and enhancing mineral mineralization. During mineral beneficiation, this prevents minerals from settling at the bottom of the outer shell, avoiding the accumulation of coarse-grained and high-density valuable minerals at the bottom of the tank, and preventing the loss of valuable minerals due to lack of contact with bubbles. This ensures full recovery of valuable minerals, effectively improving ore flotation recovery rate, reducing resource waste, and simultaneously ensuring uniform overall pulp circulation, eliminating dead zones, and allowing all mineral particles to remain stably suspended within the pulp. This ensures thorough mixing of the gas, liquid, and solid phases, guaranteeing uniform flotation reaction and preventing localized deterioration of separation results.

[0015] 2. In this invention, during the movement of the foaming plate to prevent minerals from settling, it comes into contact with the slurry and further generates bubbles at the bottom of the shell, thus achieving three-dimensional aeration throughout the flotation cell. This overcomes the shortcomings of traditional top aeration, which suffers from insufficient bottom air volume. It allows suspended mineral particles at the bottom of the cell to directly contact the bubbles, effectively improving the mineralization efficiency of coarse-grained, high-density minerals, reducing the retention and loss of valuable minerals, and increasing mineral recovery. The reciprocating motion of the foaming plate simultaneously creates mechanical disturbance, further enhancing the anti-settling effect and optimizing the flow field at the bottom of the cell. Simultaneously, the up-and-down movement of the foaming plate self-cleans the micropores, preventing slurry particles from clogging the air outlets, ensuring continuous and stable gas production, and reducing... With low operation and maintenance costs, it stabilizes the stratification interface and foam state within the tank, improving sorting performance while ensuring long-term continuous operation of the equipment. During gas delivery, the unblocking plate moves downwards and contacts the holes on the surface of the filter plate, unblocking them and maintaining the air intake channel intact and unobstructed. This effectively prevents the air intake volume from decreasing and the air supply pressure from fluctuating due to hole blockage, ensuring stable operation of the gas delivery system and continuously producing bubbles of uniform size. At the same time, it avoids airflow deviation caused by local blockage, maintains the original rectification function of the filter plate, and ensures that its physical barrier performance is not affected, continuously preventing slurry backflow and protecting precision pneumatic components such as fans and regulating valves.

[0016] 3. In this invention, during the foaming process, the downward movement of the pressure plate compresses the space inside the storage tank, forcing the foaming agent inside the storage tank to enter the interior of the spray plate through the pipe. The agent is then sprayed onto the interior of the outer shell, enabling automatic and precise dispensing of the foaming agent. Compared to manual feeding, this effectively avoids inconsistent dosage, stably controlling the number, size, and toughness of bubbles, preventing premature bubble rupture or over-foaming, and constructing a uniform and regular foam layer. This ensures sufficient mineral mineralization and flotation. Precise agent control not only improves the recovery rate of valuable minerals but also avoids excessive foaming agent causing gangue impurities to be carried into the foam, effectively improving concentrate quality. Simultaneously, the agent is evenly sprayed into the slurry, resulting in better mixing and a more balanced flotation reaction. No manual intervention is required for dosing, significantly reducing unnecessary foaming agent consumption and lowering production consumables. This system reduces costs, minimizes process fluctuations caused by human operation, and ensures long-term continuous and efficient operation of the equipment. When the angle of the agitator plate needs to be adjusted, it can be limited to dynamically change the intensity of slurry disturbance and the direction of fluid push, achieving flexible adaptation to operating conditions. For coarse-grained, high-density minerals, the agitator plate tilt angle can be increased to enhance bottom disturbance and circulation thrust, effectively preventing mineral sedimentation and ensuring uniform particle suspension for flotation. When dealing with fine-grained minerals and high-viscosity slurries, the tilt angle can be reduced to weaken turbulence intensity, preventing gangue and tailings from rolling into the froth layer and significantly improving concentrate purity. At the same time, a reasonable tilt angle can reduce the operating resistance of the agitator plate, reduce power consumption and component wear, stabilize the flotation stratification interface in the cell, ensure uniform froth layer morphology, and keep the entire equipment in optimal sorting condition for a long time, balancing sorting performance and operating economy.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please see Figures 1-4 One embodiment of the present invention is: an adaptive adjustable mineral flotation and cleaning device, comprising a housing 1, a feed trough 2 mounted on the housing 1, a servo motor 3 mounted on the housing 1, a pulley assembly 4 mounted on the output end of the servo motor 3, and a rotating shaft 5 mounted on the pulley assembly 4. Rotation of the pulley assembly 4 drives the rotating shaft 5 to rotate via a belt. A controller is provided on the servo motor 3 for adjusting the output power of the servo motor 3. The adaptive adjustable mineral flotation and cleaning device further includes: The agitation mechanism, installed on the outer shell 1, is used to generate foam inside the outer shell 1 to combine the minerals with the foam, agitate the minerals to prevent them from depositing at the bottom of the outer shell 1, and avoid the accumulation of coarse-grained minerals and high-density valuable minerals at the bottom of the tank. An anti-sinking mechanism, installed on the outer casing 1, is used to prevent minerals from sinking to the bottom and improve the flotation effect of minerals.

[0021] The stirring mechanism includes a stirring plate 7 mounted on a rotating shaft 5, which rotates when the rotating shaft 5 rotates, a connecting pipe 6 mounted on the outer casing 1, and an air inlet pipe 8 mounted on the connecting pipe 6. The stirring plate 7 is used to stir the liquid to generate bubbles, and the air inlet pipe 8 is used to inject air to assist in generating bubbles.

[0022] In this embodiment, during the flotation process, the ground slurry enters the interior of the outer shell 1 through the connecting pipe 6 and the feed trough 2. At this time, gas enters the connecting pipe 6 through the air pump inlet pipe 8. Simultaneously, the servo motor 3 starts, driving the pulley assembly 4 to rotate. The rotation of the pulley assembly 4 drives the rotating shaft 5 to rotate via the belt. The rotation of the rotating shaft 5 drives the stirring plate 7 to rotate. The rotation of the stirring plate 7 disturbs the slurry inside the outer shell 1, ensuring that mineral particles of different sizes are uniformly suspended in the slurry. This prevents high-density useful minerals and coarse-grained ore from accumulating and stagnating at the bottom of the tank, ensuring that all mineral particles can participate in the flotation reaction and reducing resource loss. Simultaneously, the air pump supplies gas into the slurry... Air is supplied, and the initially formed bubbles are large in volume, easily agglomerate, and rise quickly. The rotating agitator plate 7 continuously cuts and disperses the rising airflow and bubbles, breaking down large bubbles into tiny bubbles. Relying on the slurry flow field formed by agitation, the tiny bubbles are evenly dispersed throughout the entire cross-section of the flotation cell, avoiding local gas accumulation. The tiny bubbles have a larger specific surface area, creating favorable conditions for mineral adsorption and improving the adsorption effect. At the same time, the output power of the servo motor 3 is dynamically adjusted by the controller based on ore particle size, slurry concentration, and operating conditions. The speed is increased for coarse-grained ores to prevent them from settling to the bottom, and decreased for fine-grained ores to prevent gangue from being stirred into the foam, thus improving concentrate quality. Combined with air pump aeration, the size and distribution of bubbles are changed, the bubble residence time is extended, and the mineralization effect is enhanced.

[0023] The anti-sinking mechanism includes a second servo motor 9 mounted on the outer casing 1, a reciprocating screw 10 mounted on the output end of the second servo motor 9, a second pulley assembly 11 mounted on the reciprocating screw 10, a rotating rod 12 mounted on the second pulley assembly 11, a deflector plate 13 mounted on the rotating rod 12, a moving plate 14 mounted on the reciprocating screw 10, an anti-sinking plate 15 mounted on the moving plate 14, a long plate 16 mounted on the outer casing 1, a spiral plate 17 mounted on the moving plate 14, and a transmission wheel 18 mounted on the spiral plate 17. The deflector plate 13 is used to push out foam. The rotation of the reciprocating screw 10 will drive the moving plate 14 to move left and right through the reciprocating thread groove on its surface.

[0024] The transmission wheel 18 is rotatably connected to the long plate 16. During the movement of the transmission wheel 18, it will contact the long plate 16. The anti-sinking plate 15 is rotatably connected to the outer shell 1. The reciprocating screw 10 is rotatably connected to the outer shell 1. The rotating rod 12 is rotatably connected to the outer shell 1. The rotating shaft 5 is rotatably connected to the outer shell 1. The rotation of the rotating rod 12 can drive the actuating plate 13 to rotate.

[0025] During the mineral processing, the servo motor 29 starts and drives the reciprocating screw 10 to rotate. The rotation of the screw 10, through the reciprocating threaded grooves on its surface, causes the moving plate 14 to move left and right. During this movement, the moving plate 14 moves the anti-settling plate 15. The anti-settling plate 15 contacts the minerals deposited at the bottom of the outer shell 1 and agitates them, preventing minerals from settling at the bottom of the shell 1. This avoids the accumulation of coarse-grained and high-density valuable minerals at the bottom of the tank, preventing valuable minerals from being lost due to lack of contact with air bubbles, thus fully recovering valuable minerals, effectively improving the ore flotation recovery rate, reducing resource waste, ensuring uniform overall pulp circulation, eliminating dead zones, and allowing all mineral particles to remain stably suspended within the pulp. This ensures thorough mixing of the gas, liquid, and solid phases, guaranteeing uniform flotation reaction and preventing localized deterioration of the separation effect. Simultaneously, the bottom accumulation of material rubs against the stirring plate 7, reducing the probability of equipment wear, minimizing material blockage, and lowering the frequency of equipment maintenance and operating costs. During the movement of the anti-sinking plate 15, the transmission wheel 18 moves, contacting the long plate 16 and generating friction, causing it to rotate. This rotation drives the spiral plate 17, which in turn agitates the ore solution, reducing the probability of minerals settling. When minerals are adsorbed onto the foam surface, the reciprocating screw 10 rotates, driving the pulley group 11 to rotate. This rotation drives the rotating rod 12, which in turn drives the agitator plate 13 to rotate. The rotating agitator plate 13 then contacts the froth, pushing the froth out and completing the mineral separation process.

[0026] Example 2: Please see Figures 4-6 Based on the above embodiments, in another embodiment of the present invention, the anti-sinking mechanism includes a disturbance mechanism 19 installed on the anti-sinking plate 15. The disturbance mechanism 19 includes a fixed frame 191 installed on the anti-sinking plate 15, the movement of the fixed frame 191 will drive the rotating rod 192 to move, the rotating rod 192 installed on the fixed frame 191, the foaming plate 193 installed on the fixed frame 191, the push plate 194 installed on the rotating rod 192, and the transmission wheel 195 installed on the rotating rod 192. The foaming plate 193 is used to improve the foaming efficiency, and the transmission wheel 195 will contact the long plate 16 during the movement.

[0027] In this embodiment, during operation: to prevent minerals from settling, the movement of the anti-settlement plate 15 causes the fixed frame 191 to move, which in turn causes the rotating rod 192 to move. The rotating rod 192 then causes the transmission wheel 195 to move. During this movement, the transmission wheel 195 contacts the long plate 16, generating friction that forces it to rotate. This rotation causes the rotating rod 192 to rotate, which in turn causes the push plate 194 to rotate. The rotation of the push plate 194 pushes the foamed plate 193 downwards. This downward movement compresses the spring on the surface of the fixed frame 191. After the push plate 194 passes the foamed plate 193, the foamed plate 193 is reset by the spring, allowing the foamed plate to return to its original position. The foaming plate 193 can move up and down. During its movement, the foaming plate 193 comes into contact with the slurry and can further generate bubbles at the bottom of the outer shell 1. This enables three-dimensional air distribution throughout the flotation cell, making up for the deficiency of insufficient air volume at the bottom of the traditional upper aeration. It allows the mineral particles suspended at the bottom of the cell to come into direct contact with the bubbles, effectively improving the mineralization efficiency of coarse and high-density minerals, reducing the retention and loss of useful minerals, and increasing the mineral recovery rate. The reciprocating motion of the foaming plate 193 can simultaneously generate mechanical disturbance, further enhancing the anti-deposition effect and optimizing the flow field at the bottom of the cell. At the same time, the up and down movement of the foaming plate 193 can self-clean the micropores, preventing slurry particles from clogging the air outlets, ensuring continuous and stable gas production, reducing operation and maintenance costs, stabilizing the stratification interface and foam state in the cell, and ensuring long-term continuous operation of the equipment while improving the separation index.

[0028] The disturbance mechanism 19 also includes a filter plate 196 installed on the connecting pipe 6, an elastic telescopic rod 197 installed on the filter plate 196, a dredging plate 198 installed on the telescopic end of the elastic telescopic rod 197, and a protrusion ring 199 installed on the rotating shaft 5. The rotation of the rotating shaft 5 can drive the protrusion ring 199 to rotate, and the filter plate 196 is used to intercept the mineral liquid.

[0029] A spring is provided between the fixed frame 191 and the foam board 193. The push plate 194 is in contact with the foam board 193. The transmission wheel 195 is in contact with the long plate 16. During the rotation of the protrusion ring 199, it will contact the top of the elastic telescopic rod 197. The protrusion ring 199 and the elastic telescopic rod 197 are in contact with each other.

[0030] During gas delivery, the gas inside the connecting pipe 6 flows out through the filter plate 196. Simultaneously, the rotation of the rotating shaft 5 drives the convex ring 199 to rotate. During the rotation of the convex ring 199, it contacts the top of the elastic telescopic rod 197 and squeezes the elastic telescopic rod 197, compressing it. The compressed elastic telescopic rod 197 moves downward, causing the unblocking plate 198 to move downward. The filter plate 196 prevents the slurry from entering the air inlet pipe 8. The unblocking plate 198 moves downward and contacts the holes on the surface of the filter plate 196, clearing the holes. This keeps the air inlet channel intact and unobstructed, effectively preventing the reduction of air intake and fluctuation of air supply pressure caused by hole blockage. This ensures the stable operation of the gas delivery system, continuously producing bubbles of uniform size, while avoiding local blockage that could cause airflow turbulence. It maintains the original rectifying function of the filter plate 196 and ensures that its physical barrier performance is not affected, continuously preventing slurry backflow and protecting precision pneumatic components such as fans and regulating valves.

[0031] Example 3: Please see Figures 7-9 Based on the above embodiments, in another embodiment of the present invention, the anti-sinking mechanism further includes an adjustment mechanism 20 installed on the movable plate 14. The adjustment mechanism 20 includes a storage box 201 installed on the outer shell 1, a sliding rod 202 installed on the storage box 201, a lifting frame 203 installed on the sliding rod 202, the lifting frame 203 moving downward will drive the sliding rod 202 to move downward, a force-applying rod 206 installed on the movable plate 14, the force-applying rod 206 will contact the arc-shaped surface of the lifting frame 203 during the movement, a pressure plate 204 installed on the sliding rod 202, and a spray plate 205 installed on the outer shell 1 through a pipe.

[0032] In this embodiment, during the foaming process, the moving plate 14 moves, causing the force rod 206 to move. During this movement, the force rod 206 contacts the arc-shaped surface of the lifting frame 203, forcing it to move downwards. This downward movement causes the sliding rod 202 to move downwards, compressing the spring on the surface of the sliding rod 202. The downward movement of the sliding rod 202 then causes the pressure plate 204 to move downwards, compressing the space inside the storage box 201. This forces the foaming agent inside the storage box 201 to enter the spray plate 205 through a pipe, and then spray it onto the interior of the outer shell 1 through the spray plate 205. This allows for automatic, metered spraying of the foaming agent. Precise dosing, compared to manual feeding, effectively avoids the problem of inconsistent dosage, stably controls the number, size, and toughness of bubbles, prevents premature bubble rupture or excessive foaming, and constructs a uniform and regular foam layer, ensuring full mineralization and flotation. Precise dosing control not only improves the recovery rate of valuable minerals, but also avoids excessive foaming agent causing gangue impurities to be carried in the foam, effectively improving concentrate quality. At the same time, the reagent is evenly sprayed into the slurry, resulting in better mixing and more balanced flotation reaction. No manual intervention is required for dosing operations, greatly reducing unnecessary consumption of foaming agent, lowering production consumable costs, reducing process fluctuations caused by human operation, and ensuring long-term continuous and efficient operation of the equipment. After the force bar 206 passes over the lifting frame 203, the lifting frame 203 can be reset by spring.

[0033] The adjustment mechanism 20 also includes a fixed plate 207 mounted on the rotating rod 12, an L-shaped plate 208 mounted on the actuating plate 13, and a limiting rod 209 mounted on the L-shaped plate 208 by a spring. The movement of the limiting rod 209 will stretch the spring on the surface of the limiting rod 209. The fixed plate 207 is used to limit the limiting rod 209.

[0034] A spring is provided between the storage box 201 and the lifting frame 203, the limiting rod 209 is in contact with the fixing plate 207, and the force application rod 206 is in contact with the lifting frame 203.

[0035] When the angle of the actuating plate 13 needs to be adjusted, the operator pulls out the limiting rod 209, causing it to move away from the interior of the fixed plate 207. Simultaneously, the movement of the limiting rod 209 stretches the spring on its surface. The operator then rotates the actuating plate 13 to adjust it to the appropriate position. The limiting rod 209 is then reset by the spring, moving back into the fixed plate 207, thus limiting the actuating plate 13. This allows for dynamic changes in the intensity of slurry disturbance and the direction of fluid propulsion, achieving flexible adaptation to different operating conditions. For coarse-grained, high-density minerals, increasing the tilt angle of the agitator plate 13 enhances the bottom disturbance and circulation thrust, effectively preventing mineral sedimentation and ensuring uniform particle suspension for flotation. When dealing with fine-grained minerals and high-viscosity slurries, reducing the tilt angle weakens the turbulence intensity, preventing gangue and tailings from rolling into the froth layer and significantly improving concentrate purity. At the same time, a reasonable tilt angle reduces the operating resistance of the agitator plate 13, reduces power consumption and component wear, stabilizes the flotation stratification interface in the cell, ensures uniform froth layer morphology, and keeps the entire equipment in optimal sorting condition for a long time, balancing sorting performance and operational economy.
