Description

Technical Field

[0001] This utility model relates to the field of flotation machine technology, and in particular to an agitated flotation machine for quartz sand treatment. Background Technology

[0002] The stirred flotation machine is the core equipment for the flotation and purification of quartz sand. By stirring, the slurry, reagents and air are fully mixed to separate quartz sand from impurities such as feldspar and mica. During operation, the quartz sand slurry enters the flotation machine through the feed pipe. The stirring device inside the flotation machine keeps the slurry suspended. At the same time, the impeller rotates to draw outside air into the slurry to form microbubbles. The bubbles combine with the useful mineral particles and rise to the top surface of the slurry to form a foam layer. Finally, the scraper mechanism scrapes the foam layer off.

[0003] When using a flotation machine, collectors and frothers need to be added to the machine periodically. Collectors are usually added intermittently during the flotation process, while frothers need to be added continuously. Reagents are usually added through pipes located above the flotation machine or manually. The location of the pipes is usually fixed. The diffusion rate of the reagents after entering the flotation machine is low. Manual addition is prone to errors and requires additional labor costs, which makes reagent addition when using a flotation machine inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the problems that the position of the pipeline for adding reagents above the flotation machine is usually fixed, the diffusion rate of the reagents after entering the flotation machine is low, manual addition is prone to deviation and requires additional labor costs, which makes it inconvenient to add reagents when using the flotation machine. Therefore, this invention proposes an agitated flotation machine for quartz sand treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stirred flotation machine for quartz sand treatment, comprising a machine body, a feed pipe provided on one side of the outer surface of the machine body, an output pipe provided on one side of the bottom of the outer surface of the machine body, two sets of first servo motors provided on the top of the machine body, two housings fixedly connected inside the machine body, an impeller rotatably connected inside the housing, the output end of the first servo motor being connected to the shaft of the impeller via a pulley and belt assembly, an air inlet pipe fixedly connected to the outer surface of the housing, a second servo motor provided on one side of the top of the machine body, a scraper rotatably connected to the top of the machine body, and the output end of the second servo motor being connected to one end of the shaft of the scraper via a belt and pulley assembly.

[0006] The effects achieved by the above components are as follows: When using the flotation machine, quartz sand slurry is fed into the machine body through the feed pipe on one side of the machine body, and reagents are added into the machine body. The two first servo motors at the top of the machine body drive the impeller inside the shell to rotate through the belt pulley set. When the impeller rotates at high speed, a negative pressure zone is formed in the sealed cavity between the impeller and the shell. Outside air is drawn in through the air inlet pipe and comes into direct contact with the high-speed rotating impeller, and is cut into small and uniform bubbles. At the same time, the impeller blades strongly agitate the quartz sand slurry in the tank, so that the quartz sand particles, reagents and the sucked-in bubbles are fully mixed, breaking the static stratification of the slurry and ensuring that solid particles do not settle. Because the surface of the quartz sand is covered by the collector, the bubbles will overcome the surface tension of the slurry and adhere tightly to its surface. The second servo motor drives the scraper to rotate through the pulley belt set. When the foam layer reaches a certain thickness and stability, the rotating scraper scrapes the foam out of the machine body, completing the flotation.

[0007] Preferably, the top of the machine body is provided with an extension device, which includes a frame plate fixed to the top of the machine body. A third servo motor is provided on one side of the outer surface of the frame plate. The output end of the third servo motor is connected to a lead screw via a coupling. The two ends of the lead screw rotate on the inner wall of the frame plate. A material box is slidably connected to the top of the frame plate. A threaded block is fixedly connected to the bottom of the material box. The inner wall of the threaded block is threadedly connected to the outer surface of the lead screw. Two material slots are opened inside the material box. The bottom of the inner wall of the two material slots inside the material box is respectively provided with through holes. Two nozzles are rotatably connected to the bottom of the outer surface of the material box. The top ends of the nozzles communicate with the through holes inside the material box. Two sets of electric push rods are provided on one side of the outer surface of the material box. The output rod of the electric push rod is connected to a rubber plug via a connecting rod. The rubber plug is located inside the through hole at the bottom of the inner wall of the material box.

[0008] The effect achieved by the above components is as follows: By setting up the material box, when using the flotation machine, the frother and collector can be added separately into the two material tanks inside the material box. The control system adjusts the forward and reverse rotation program of the third servo motor and the timer to control the third servo motor to operate periodically. The timer parameters of the electric push rod on the outer surface of the material box where the collector is placed are also adjusted. When the third servo motor operates, it drives the lead screw to rotate. The threaded block at the bottom of the outer surface of the material box will move on the outer surface of the lead screw, causing the material box to slide on the top of the frame plate. At this time, an electric push rod on one side of the outer surface of the material box extends and drives the rubber plug to move through the connecting rod, causing the rubber plug to disengage from a through hole in the inner wall of the material box, allowing the frother in one of the material tanks to pass through. In practical applications, the nozzle diameter can be adjusted to output the quartz slurry into the machine body. When the material box moves to the top of the frame, the third servo motor drives the lead screw to rotate in the other direction, causing the material box to move to the other side. Another electric push rod on the outer surface of the material box operates through the connecting rod to move the rubber plug out of the through hole. The collector in another material tank inside the material box will enter the nozzle through the through hole and be output into the machine body to mix with the quartz slurry. When the material box moves in the other direction again, the electric push rod on the side of the material box containing the collector retracts, causing the rubber plug to move and close the through hole on that side. After the set time is reached, the third servo motor stops operating.

[0009] Preferably, a first toothed rod is fixedly connected to each of the top two sides of the frame plate, and a toothed ring is fixedly connected to the outer surface of the nozzle.

[0010] The effect achieved by the above components is as follows: the outer surface of the toothed ring meshes with one side of the first toothed bar. When the material box moves back and forth at the top of the frame plate, the toothed ring on the outer surface of the nozzle moves on one side of the first toothed bar at the top of the frame plate, which drives the nozzle to rotate. This causes the nozzle to rotate continuously during the movement of the material box, thus controlling the agent output from the nozzle to mix more thoroughly with the quartz sand slurry inside the machine body.

[0011] Preferably, an arc-shaped baffle is fixedly connected to the end of the nozzle away from the material box, and the baffle is located on the upper side of the end of the nozzle away from the material box.

[0012] The effect achieved by the above components is that when the agent is output through the nozzle, the arc-shaped baffle can control and guide the output direction of the agent, so that the agent is output as downward as possible and enters the machine body more accurately.

[0013] Preferably, tapered baffles are fixedly connected to both sides of the threaded block.

[0014] The effect achieved by the above components is that by setting a conical baffle, the side of the two nozzles near the threaded block can be blocked and protected, preventing the agent from being sprayed onto the surface of the other nozzle or the surface of the threaded block during the rotation of the nozzle to output the agent.

[0015] Preferably, a U-shaped toothed rod is fixedly connected to one side of the top of the frame plate, two stirring rods are rotatably connected to the top of the material box, a pulley is provided at the top of the stirring rod, a belt is sleeved on the outside of the pulley at the top of the two stirring rods, and a gear is fixedly connected to the top of one of the stirring rods, the outer surface of the gear meshing with one side of the U-shaped toothed rod.

[0016] The effect achieved by the above components is as follows: when the third servo motor drives the material box to move back and forth on the top of the frame plate, the gear at the top of one stirring rod will move on one side of the U-shaped toothed rod, causing the gear and stirring rod to rotate. The belt is driven to move through the pulley on the outer surface of the stirring rod, causing the other stirring rod to rotate as well. Thus, during the movement of the material box, the collector or foaming agent inside the material box is stirred and dispersed by the two stirring rods, thereby improving the effect of the agent.

[0017] Preferably, one side of the U-shaped toothed rod is provided with an inclined rod for supporting the U-shaped toothed rod, and the inclined rod is obliquely installed at the top of the material box and fixedly connected to the U-shaped toothed rod.

[0018] The effect achieved by the above components is that by setting the diagonal bar, one side of the U-shaped toothed bar can be supported, thereby improving the structural stability of the connection between the U-shaped toothed bar and the material box.

[0019] Preferably, positioning wheels are rotatably connected to both sides of the outer surface of the material box, and the outer surface of the positioning wheels rolls on one side of the top of the frame plate.

[0020] The effect achieved by the above components is that when the material box moves at the top of the shelf, the positioning wheels on both sides of the outer surface of the shelf will roll on both sides of the outer surface of the shelf. The positioning wheels can further limit the angle between the material box and the shelf, increasing the stability of the material box when it moves.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] (1) By setting up an extension device, by adding appropriate amounts of collector and frother to the two troughs inside the material box respectively, the material box moves back and forth on the top of the frame plate by periodically operating the third servo motor during the operation of the flotation machine. During the movement of the material box, the frother inside the material box is continuously added to the machine body. At the same time, a set of electric push rods on the outer surface of the material box operates intermittently to allow the collector inside the material box to enter the machine body, which facilitates the periodic addition of collector and frother and improves the convenience of using the flotation machine.

[0023] (2) By using the stirring rod to stir the agent inside the material box during the movement of the material box, and controlling the nozzle to continuously rotate to output the agent in different directions inside the machine body, the effect of adding and using the agent is improved.

[0032] Example 1, such as Figure 1-2As shown, a stirred flotation machine for quartz sand treatment includes a body 1. A feed pipe 3 is located on one side of the outer surface of the body 1, and an output pipe is located on the bottom side of the outer surface of the body 1. Two sets of first servo motors 4 are located at the top of the body 1. Two housings 5 ​​are fixedly connected inside the body 1, and impellers 6 are rotatably connected inside the housings 5. The output ends of the first servo motors 4 are connected to the shafts of the impellers 6 via pulleys and belts. An air inlet pipe 7 is fixedly connected to the outer surface of the housings 5. A second servo motor 8 is located on one side of the top of the body 1, and a scraper 9 is rotatably connected to the top of the body 1. The output end of the second servo motor 8 is connected to one end of the shaft of the scraper 9 via a belt and pulley system. When using the flotation machine, quartz sand slurry is fed into the body 1 through the feed pipe 3 on one side of the body 1, and reagents are added into the body 1. The operation of the top of the body 1... The two first servo motors 4 drive the impeller 6 inside the housing 5 to rotate via belt and pulley assembly. When the impeller 6 rotates at high speed, a negative pressure zone is formed in the sealed cavity between the impeller 6 and the housing 5. Outside air is drawn in through the air inlet pipe 7 and comes into direct contact with the high-speed rotating impeller 6, where it is cut into small, uniform bubbles. At the same time, the blades of the impeller 6 strongly agitate the quartz sand slurry in the tank, so that the quartz sand particles, reagents and the sucked-in bubbles are fully mixed, breaking the static stratification of the slurry and ensuring that solid particles do not settle. Because the surface of the quartz sand is covered by the collector, the bubbles will overcome the surface tension of the slurry and adhere tightly to its surface. The second servo motor 8 drives the scraper 9 to rotate via belt and pulley assembly. When the foam layer reaches a certain thickness and stability, the rotating scraper 9 scrapes the foam out of the machine body 1, completing the flotation.

[0033] Reference Figure 1-7As shown in this embodiment: an extension device 2 is provided at the top of the machine body 1. The extension device 2 includes a frame plate 21, which is fixed to the top of the machine body 1. A third servo motor 22 is provided on one side of the outer surface of the frame plate 21. A lead screw 23 is installed at the output end of the third servo motor 22 through a coupling. The two ends of the lead screw 23 rotate at the two ends of the inner wall of the frame plate 21. A material box 24 is slidably connected to the top of the frame plate 21. A threaded block 25 is fixedly connected to the bottom of the material box 24. The inner wall of the threaded block 25 is threadedly connected to the outer surface of the lead screw 23. Two material slots are opened inside the material box 24. Through holes are opened at the bottom of the inner wall of the two material slots inside the material box 24. Two nozzles 26 are rotatably connected to the bottom of the outer surface of the material box 24. The top of the nozzles 26 are connected to the material box 24. The internal through-hole is open, and two sets of electric push rods 27 are provided on one side of the outer surface of the material box 24. The output rod of the electric push rod 27 is connected to a rubber plug 28 through a connecting rod. The rubber plug 28 is located inside the through-hole at the bottom of the inner wall of the material box 24. By setting up the material box 24, when using the flotation machine, the frother and the collector can be added to the two material tanks inside the material box 24 respectively. The control system adjusts the forward and reverse rotation program of the third servo motor 22 and the timer to control the third servo motor 22 to operate periodically, and adjusts the timer parameters of the electric push rod 27 on the outer surface of the material box 24 on the side where the collector is placed. When the third servo motor 22 operates, it drives the lead screw 23 to rotate. The threaded block 25 at the bottom of the outer surface of the material box 24 will move on the outer surface of the lead screw 23, causing the material box 24 to move on the support plate 21. When the top of the material box 24 slides, an electric push rod 27 on one side of the outer surface of the material box 24 extends and moves the rubber plug 28 through the connecting rod, causing the rubber plug 28 to disengage from a through hole in the inner wall of the material box 24. This allows the foaming agent in one of the material troughs to enter the nozzle 26 through the through hole. In practical applications, the diameter of the nozzle 26 can be adjusted, and the internal output is to the quartz mortar inside the machine body 1. When the material box 24 moves to the top side of the frame plate 21, the third servo motor 22 drives the lead screw 23 to rotate in the other direction, causing the material box 24 to move to the other side. Another electric push rod 27 on the outer surface of the material box 24 moves and moves the rubber plug 28 out of the through hole through the connecting rod. The collector in another material trough inside the material box 24 will enter the nozzle 26 through the through hole and be output to the machine body 1. The material box 24 is mixed with quartz sand slurry inside the body 1. When the material box 24 moves in another direction, the electric push rod 27 on the side containing the collector inside the material box 24 retracts, causing the rubber stopper 28 to move and seal the through hole on that side. After a set time, the third servo motor 22 stops operating. By setting the expansion device 2, appropriate amounts of collector and frother are added to the two material tanks inside the material box 24 respectively. During the operation of the flotation machine, the third servo motor 22 is periodically operated to control the material box 24 to move back and forth on the top of the frame plate 21. During the movement of the material box 24, the frother inside the material box 24 is continuously added to the inside of the machine body 1. At the same time, a set of electric push rods 27 on the outer surface of the material box 24 operates intermittently to allow the collector inside the material box 24 to enter the inside of the machine body 1.This allows for convenient and regular addition of collectors and frothers, improving the ease of use of the flotation machine.

[0034] Reference Figure 2-6 As shown in this embodiment: First toothed rods 29 are fixedly connected to both sides of the top of the frame plate 21, and a toothed ring 210 is fixedly connected to the outer surface of the nozzle 26. The outer surface of the toothed ring 210 meshes with one side of the first toothed rod 29. When the material box 24 moves back and forth at the top of the frame plate 21, the toothed ring 210 on the outer surface of the nozzle 26 moves on one side of the first toothed rod 29 at the top of the frame plate 21, causing the nozzle 26 to rotate. This allows the nozzle 26 to rotate continuously during the movement of the material box 24, controlling the agent output from the nozzle 26 to mix more thoroughly with the quartz sand slurry inside the machine body 1. The end of the nozzle 26 away from the material box 24 is fixed. An arc-shaped baffle 211 is connected to the nozzle 26, located above the end of the nozzle 26 away from the material box 24. When the agent is output through the nozzle 26, the arc-shaped baffle 211 can control and guide the output direction of the agent, so that the agent is output as downward as possible and enters the machine body 1 more accurately. Conical baffles 216 are fixedly connected to both sides of the threaded block 25. By setting the conical baffles 216, the side of the two nozzles 26 near the threaded block 25 can be blocked and protected, so as to prevent the agent from being sprayed onto the surface of the other nozzle 26 or the surface of the threaded block 25 during the rotation of the nozzle 26 to output the agent.

[0035] Reference Figure 2-6 As shown in this embodiment: a U-shaped toothed rod 212 is fixedly connected to one side of the top of the frame plate 21. Two stirring rods 213 are rotatably connected to the top of the material box 24. The top of the stirring rod 213 is provided with a pulley. A belt is sleeved on the outside of the pulley at the top of the two stirring rods 213. A gear 214 is fixedly connected to the top of one stirring rod 213. The outer surface of the gear 214 meshes with one side of the U-shaped toothed rod 212. When the third servo motor 22 drives the material box 24 to move back and forth at the top of the frame plate 21, the gear 214 at the top of one stirring rod 213 will move on one side of the U-shaped toothed rod 212, causing the gear 214 and the stirring rod 213 to rotate. The belt is driven to move through the pulley on the outer surface of the stirring rod 213, causing the other stirring rod 213 to rotate accordingly. Thus, during the movement of the material box 24, the two stirring rods 213 stir and disperse the collector or foaming agent inside the material box 24, improving the effect of the agent.

[0036] Reference Figure 2-6As shown in this embodiment: a diagonal bar is provided on one side of the U-shaped toothed rod 212 for supporting the U-shaped toothed rod 212. The diagonal bar is installed obliquely at the top of the material box 24 and fixedly connected to the U-shaped toothed rod 212. By setting the diagonal bar, one side of the U-shaped toothed rod 212 can be supported, improving the structural stability of the connection between the U-shaped toothed rod 212 and the material box 24. Positioning wheels 215 are rotatably connected to both sides of the outer surface of the material box 24. The outer surface of the positioning wheels 215 rolls on one side of the top of the frame plate 21. When the material box 24 moves on the top of the frame plate 21, the positioning wheels 215 on both sides of the outer surface will roll on both sides of the outer surface of the frame plate 21. The positioning wheels 215 can further limit the angle between the material box 24 and the frame plate 21, increasing the stability of the material box 24 when it moves.

[0037] Working Principle: When using the flotation machine, quartz sand slurry is fed into the machine body 1 through the feed pipe 3 on one side of the machine body 1. The frother and collector are added to the two troughs inside the material box 24, respectively. The control system adjusts the forward and reverse rotation program of the third servo motor 22 and the timer to control the third servo motor 22 to operate periodically. The timer parameters of the electric push rod 27 on the outer surface of the material box 24 where the collector is placed are also adjusted. Simultaneously, the initial frother and collector are added into the machine body 1. The two first servo motors 4 at the top of the machine body 1 drive the impeller 6 inside the housing 5 to rotate via a belt pulley assembly. When the impeller 6 rotates at high speed, a negative pressure zone is formed in the sealed cavity between the impeller 6 and the housing 5. Outside air is drawn in through the air inlet pipe 7, and the high-speed rotating impeller... Impeller 6 directly contacts and cuts the foam into fine, uniform bubbles. Simultaneously, the blades of impeller 6 powerfully agitate the quartz sand slurry in the tank, ensuring thorough mixing of the quartz sand particles, reagents, and the absorbed bubbles. This breaks up the static stratification of the slurry, preventing solid particles from settling. Because the surface of the quartz sand is covered by the collector, the bubbles overcome the surface tension of the slurry and adhere tightly to its surface. The second servo motor 8 drives the scraper 9 to rotate via a pulley and belt assembly. When the foam layer reaches a certain thickness and stability, the rotating scraper 9 scrapes the foam out of the machine body 1. When the third servo motor 22 operates, it drives the lead screw 23 to rotate. The threaded block 25 at the bottom of the outer surface of the material box 24 moves on the outer surface of the lead screw 23, causing the material box 24 to slide on the top of the frame plate 21. An electric push rod 27 on one side of the outer surface of the box 24 extends and moves a rubber stopper 28 via a connecting rod, causing the rubber stopper 28 to disengage from a through hole in the inner wall of the box 24. This allows the foaming agent in one of the material troughs to enter the nozzle 26 through the through hole. In practical applications, the diameter of the nozzle 26 can be adjusted, and the internal output is into the quartz mortar inside the machine body 1. When the box 24 moves to the top side of the frame plate 21, the third servo motor 22 drives the lead screw 23 to rotate in the other direction, causing the box 24 to move to the other side. Another electric push rod 27 on the outer surface of the box 24 moves and moves the rubber stopper 28 away from the through hole via a connecting rod. The collecting agent in another material trough inside the box 24 will enter the nozzle 26 through the through hole and be output into the machine body 1 to mix with the quartz mortar. During mortar mixing, when the material box 24 moves in another direction, the electric push rod 27 controlling the side containing the collector inside the material box 24 retracts, causing the rubber plug 28 to move and seal the through hole on that side. As the material box 24 moves back and forth at the top of the frame plate 21, the toothed ring 210 on the outer surface of the nozzle 26 moves on one side of a first toothed rod 29 at the top of the frame plate 21, causing the nozzle 26 to rotate. This ensures the nozzle 26 rotates continuously as the material box 24 moves. Simultaneously, as the material box 24 moves back and forth at the top of the frame plate 21, the gear 214 at the top of one stirring rod 213 moves on one side of a U-shaped toothed rod 212, causing the gear 214 and the stirring rod 213 to rotate. This rotation, via the pulley on the outer surface of the stirring rod 213, drives the belt to move, causing the other stirring rod 213 to rotate as well.This allows the collector or foaming agent inside the material box 24 to be stirred and dispersed by the two stirring rods 213 during its movement. After the set time is reached, the third servo motor 22 stops operating.
