Description

Technical Field

[0001] This invention relates to the field of mineral flotation technology, specifically to an automatic sequential flotation device and method for lead-zinc ore. Background Technology

[0002] As is generally known, flotation equipment is a mechanical device used in froth flotation to separate target minerals from ores. Carrier flotation, under conventional flotation conditions, utilizes a coarse-grained auxiliary material as a carrier in the flotation process. By adding an appropriate amount of collector, both the fine lead-zinc ore particles and the carrier become sufficiently hydrophobic. Taking advantage of the tendency of hydrophobic fine particles to adhere to hydrophobic coarse particles, the fine particles selectively coat the carrier, or the principle of hydrophobic agglomeration is used to allow microparticles to adhere to the surface of easily floatable coarse ore particles. Then, air bubbles float the carrier along with the fine mineral particles. Carrier flotation of fine-grained lead-zinc ore is a common ore flotation method used to extract valuable minerals from lead-zinc ores. This flotation method utilizes the difference in affinity between ore particles and air bubbles, causing the valuable minerals to float together with the air bubbles, thereby achieving the separation and extraction of the ore.

[0003] For example, patent application CN101804388B, published on September 11, 2013, entitled "Flotation Machine Drive Device and Flotation Machine with Such Drive Device," relates to a flotation machine drive device. The motor (1) of this drive device is directly connected to the main shaft (2) of the flotation machine via a flange or coupling. The motor (1) directly drives the main shaft (2) of the flotation machine to rotate, thereby rotating the impeller (3). This invention also provides a flotation machine. This invention simplifies the structure of the flotation machine, optimizes its structure without changing its process performance, and simplifies its manufacturing process.

[0004] In existing flotation machines, the consistent orientation of the gas input pipe during gas delivery operations results in a fixed direction for bubble generation, leading to uneven flotation of bubbles within the machine and impacting the flotation of the ore body. Summary of the Invention

[0007] As mentioned above, a baffle 6 is provided in the part of the flotation frame located between two adjacent drive shaft sleeves, and the baffle 6 divides the flotation frame into multiple identical flotation spaces.

[0008] As described above, a feed pipe is provided on the side wall of the flotation frame and in the middle of each of the flotation spaces, and a discharge pipe is provided on the side wall of the flotation frame and at the bottom of each of the flotation spaces.

[0009] As mentioned above, a sliding groove is provided on each side wall of each of the baffles, and a sliding groove is provided on each of the two side walls of the flotation frame opposite to the baffles. A push plate is installed in each sliding groove in a sliding fit manner, and the push plate is located at the bottom end of the L-shaped tube.

[0010] As described above, each of the flotation spaces is equipped with an active disk at its bottom end in a rotatable manner, and the active disk and the bottom end of the L-shaped tube are connected by a connector.

[0016] The beneficial effects of this invention are as follows: when the bubble generating pipe conveys gas into the flotation frame, the drive shaft sleeve drives the L-shaped pipe to rotate at the bottom of the bubble generating pipe, so that the gas in the bubble generating pipe is conveyed into the flotation frame through the L-shaped pipe. This makes the bubbles generated in all directions within the flotation frame by the rotating L-shaped pipe more uniform, thereby improving the flotation effect of the ore body.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 9 As shown in the figure, an automatic sequential flotation device for lead-zinc ore provided in this embodiment of the invention includes a flotation frame 1. Multiple active shaft sleeves 2 are uniformly installed on the flotation frame 1 in a rotatable manner. Multiple impellers 3 are sleeved on each active shaft sleeve 2. A bubble generating tube 4 is sleeved inside each active shaft sleeve 2. An L-shaped tube 5 is installed at the bottom end of each bubble generating tube 4 in a rotatable manner, and the L-shaped tube 5 is connected to its corresponding active shaft sleeve 2 to rotate with the active shaft sleeve.

[0031] Specifically, the interior of flotation frame 1 is used to hold the flotation liquor and ore. Highly efficient dispersants and pH adjusters disperse fine-grained gangue minerals and slime in the pulp. During flotation of lead-zinc ore, due to the different hydrophobicities of lead and zinc ore, xanthate collectors and non-polar oils are used to selectively hydrophobically agglomerate the fine-grained lead-zinc ore. This causes the lead ore to float on the surface of the liquid within flotation frame 1, while the zinc ore sinks into the liquid within flotation frame 1. A float chamber is provided on the discharge side of flotation frame 1 to collect the ore body after flotation (i.e., the lead ore floating on the surface of flotation frame 1). The impeller 3 is driven to rotate by the drive shaft sleeve 2, which agitates the ore and flotation liquor, causing the ore to float and sink (i.e., to be inside the flotation liquor). The bubble generating pipe 4 is connected to the flotation frame 1 in a through-hole manner. The end of the bubble generating pipe 4 located outside the flotation frame 1 is connected to the gas generating equipment, and the end of the bubble generating pipe 4 located inside the flotation frame 1 is rotatably connected to the L-shaped pipe 5. The rotatable connection is equipped with a dynamic sealing structure. In this way, the bubble generating pipe 4 and the L-shaped pipe 5 are responsible for introducing the airflow into the flotation frame 1 to react with the flotation process. The liquid and ore are mixed to generate bubbles. During the flotation operation of lead-zinc ore, each drive shaft sleeve 2 is synchronously driven to rotate the impeller 3, which agitates the ore body (i.e., lead-zinc ore) being flotated. During the agitation process, airflow is introduced into the flotation frame 1 through the bubble generating pipe 4 and L-shaped pipe 5 to mix with the flotation liquid and ore to generate bubbles. This causes the lead ore particles in the flotation frame 1 to adhere to the flotation bubbles and float to the surface, thus separating the lead-zinc ore and performing flotation processing. This is common knowledge in the field and will not be elaborated further. In existing flotation machines, when gas is being transported... Because the gas input pipes are aligned in the same direction, the direction of bubble generation remains unchanged, resulting in uneven flotation of bubbles inside the flotation machine and affecting the flotation operation of the ore body. In this embodiment, when the bubble generating pipe 4 delivers gas to the flotation frame 1, the drive shaft sleeve 2 drives the L-shaped pipe 5 to rotate at the bottom of the bubble generating pipe 4. This allows the gas inside the bubble generating pipe 4 to be delivered to the flotation frame 1 through the L-shaped pipe 5. The rotating L-shaped pipe 5 generates bubbles in all directions within the flotation frame 1, making the bubble generation more uniform and improving the flotation effect of the ore body.

[0032] Furthermore, a baffle 6 is provided in the part of the flotation frame 1 located between two adjacent drive shaft sleeves 2. The baffle 6 divides the flotation frame 1 into multiple identical flotation spaces. Specifically, by setting the baffle 6 between two adjacent drive shaft sleeves 2, the flotation frame 1 can be divided into multiple identical flotation spaces, so that the flotation operation of lead-zinc ore in each flotation space will not affect each other.

[0033] Furthermore, a feed pipe 7 is provided on the side wall of the flotation frame 1 and at the center of each flotation space, and a discharge pipe 8 is provided on the side wall of the flotation frame 1 and at the bottom of each flotation space. Specifically, the ore body (i.e., lead-zinc ore) is transported to the flotation space of each flotation frame 1 through the feed pipe 7, and the residual material (such as zinc ore or mudstone) inside the flotation frame 1 is discharged from the flotation space through the discharge pipe 8, so that repeated flotation operations can be performed in the flotation space. The residual material (such as zinc ore or mudstone) inside the flotation frame 1 is collected after being discharged from the flotation space. After the lead ore in the flotation frame 1 is floated, the flotation liquid in the flotation frame 1 is replaced, and the residual material is transported to the flotation space through the feed pipe 7 to perform flotation operations on the zinc ore. This allows the ore body (lead-zinc ore) to be processed by flotation in sequence to obtain the material that needs to be floated in the ore body.

[0034] Furthermore, a groove 9 is provided on each side wall of each of the baffles 6, and a groove 9 is provided on each of the two side walls of the flotation frame 1 opposite to the baffles 6. A pusher plate 10 is installed in each groove 9 in a sliding fit, and the pusher plate 10 is located at the bottom end of the L-shaped tube 5. An active disk 11 is installed at the bottom end of each of the flotation spaces in a rotatable fit, and the active disk 11 and the bottom end of the L-shaped tube 5 are connected by a connector 12. The top of the active disk 11 is a high-low surface 13, and the high-low surface 13 of the active disk 11 is the L-shaped tube 5. The lower bottom surface 131 (that is, the center of the part of the L-shaped tube 5 facing the lower surface 131, i.e., the center point of the arc surface of the bottom surface 131 and the center of the discharge part of the L-shaped tube 5 coincide) is on one side, and the higher top surface 132 is on the other side. The top surface 132 and the bottom surface 131 are connected by a wedge-shaped surface 133. The bottom surface of each of the push plates 10 is attached to the lower surface 13. Specifically, when the drive shaft sleeve 2 drives the L-shaped tube 5 to rotate at the bottom end of the bubble generating tube 4, the direction of gas output in the L-shaped tube 5 follows the direction of the main drive shaft sleeve 132. The direction of bubble generation changes with the rotation of the active bushing 2 (that is, the direction of bubble generation changes with the rotation of the active bushing 2). At the same time, the L-shaped pipe 5 drives the active disc 11 to rotate through the connector 12. During the rotation of the active disc 11 by the L-shaped pipe 5: (1) When one end of the bottom surface 131 of the active disc 11 and the bottom end of the push plate 10 on one side (such as the right side) abut against each other, at the same time, the top surface 132 of the active disc 11 and the bottom end of the push plate 10 on the other side (such as the left side) abut against each other. Since the L-shaped pipe 5 is directed towards the push plate 10 on the side (such as the right side) that abuts against the bottom surface 131, the direction of bubble generation changes with the rotation of the active bushing 2. 0, causing the gas discharged from the L-shaped pipe 5 to blow towards the push plate 10 on the side (such as the right side) that abuts against the bottom surface 131, so that bubbles are generated on the push plate 10 on one side (such as the right side) to continue driving the L-shaped pipe 5 and the active disk 11 to rotate. During the process of the push plate 10 sliding from one end of the bottom surface 131 (or one end of the top surface 132) to the wedge surface 133 position of the active disk 11, the bottom end of the push plate 10 slides along the trajectory of the active disk 11. Since the bottom surface 131 and the top surface 132 of the active disk 11 are both flat, the push plate 10 will not slide in the groove 9 at this time.(2) When the wedge-shaped surface 133 on the active disk 11 and the push plate 10 abut against each other (that is, when the push plate 10 slides along the trajectory of the wedge-shaped surface 133 on the active disk 11), the push plate 10 on one side (such as the right side) slides along the trajectory of the chute 9 towards its top, so that the push plate 10 can push the bubbles towards the top of the flotation space, so that the push plate 10 pushes the bubbles generated by the bubble generating pipe 4 and the L-shaped pipe 5 in the flotation space towards the top of the flotation space, so that the bubbles and the ore body (that is, lead ore) adhere to each other and float to the top, so that the lead ore moves towards the top of the flotation space, and the ore body (that is, lead ore) can be flotated. The push plate on the other side (such as the left side) 10 slides along the trajectory of the chute 9 to its bottom end, which facilitates the next push of the bubble to the top of the flotation space. At the same time, the up-and-down reciprocating motion of the push plate 10 can stir the ore body, making the stirring of the ore body more uniform. During this process, the part of the L-shaped pipe 5 between the push plate 10 on one side (such as the right side) and the push plate 10 on the other side (such as the left side) rotates; (3) After the push plate 10 slides along the trajectory of the wedge surface 133, the L-shaped pipe 5 and the active disc 11 continue to rotate, so that the push plate 10 on one side (such as the right side) slides to the top of the chute 9 (that is, the push plate 10 is pressed against the top surface 132 of the high and low surface 13). The system can push bubbles to a certain position at the top of the flotation space. Meanwhile, the pusher plate 10 on the other side (as on the left) slides to its bottom end within the chute 9 (i.e., the pusher plate 10 is pressed against the bottom surface 131 of the high-low surface 13). At this time, the L-shaped tube 5 faces the pusher plate 10 on the other side (as on the left), causing the gas blown out of the L-shaped tube 5 to face the pusher plate 10 on the other side (as on the left). The system continues to drive the L-shaped tube 5 and the active disk 11 to rotate until the pusher plate 10 is pressed against the wedge surface 133 and slides along the trajectory of the wedge surface 133. At the same time, the pusher plate 10 on the other side (as on the left) slides along the trajectory of the chute 9 towards its top, causing the pusher plate 10 on the other side (as on the left) to push the bubbles... Pushing towards the top of the flotation space, the pusher plate 10 on one side (e.g., the right side) slides along the trajectory of the chute 9 towards its bottom, facilitating the next push of bubbles towards the top of the flotation space. Repeating this operation, as the L-shaped pipe 5 and the active disc 11 rotate, the pusher plate 10 can reciprocate within the chute 9, stirring the ore body and making the stirring more uniform. Furthermore, the L-shaped pipe 5 always faces the pusher plate 10, which is in contact with the bottom surface 131, ensuring that bubbles are always generated on the bottommost pusher plate 10. This allows the pusher plate 10 to push bubbles towards the top of the flotation space during its ascent, enabling stable flotation of the ore body.

[0035] In another embodiment of the present invention, the discharge pipe 8 extends into the flotation frame 1 and abuts against the outer wall of the active disk 11, so that when the top surface 132 of the active disk 11 abuts against the discharge pipe 8, it performs a sealing operation; when the bottom surface 131 of the active disk 11 abuts against the discharge pipe 8, it performs a desealing operation. Specifically, during one rotation of the active disk 11, when the top surface 132 of the active disk 11 abuts against the discharge pipe 8, because the height of the top surface 132 of the active disk 11 is relatively high, the active disk 11 performs a sealing operation on the discharge pipe 8. When the bottom surface 131 of the active disk 11 abuts against the discharge pipe 8, because the height of the bottom surface 131 of the active disk 11 is relatively low, the active disk 11 performs a desealing operation on the discharge pipe 8, so that the discharge pipe 8 can perform a discharge operation. That is, as the active disk 11 rotates, the discharge pipe 8 can perform an intermittent discharge operation (e.g., Figure 9 As shown), and because there is a wedge-shaped surface 133 on the high and low surfaces 13, the ore body on the active disc 11 slides from the top surface 132 from the wedge-shaped surface 133 to the bottom surface 131, so that the active disc 11 has a certain gathering effect on the ore body, making the discharge pipe 8 more stable when discharging.

[0036] Preferably, each of the push plates 10 has a plurality of balls 14 evenly arranged at its bottom end in a rotatable manner, and the balls 14 abut against the high and low surfaces 13. Specifically, when the bottom end of the push plate 10 slides along the trajectory of the high and low surfaces 13, the balls 14 at the bottom end of the push plate 10 abut against the high and low surfaces 13, reducing the rotational friction between the high and low surfaces 13 and the push plate 10, changing the planar friction to rolling friction, and improving the smoothness of the sliding of the push plate 10.

[0037] Preferably, the top ends of each of the push plates 10 and the top ends of the chute 9 are connected by elastic members 15. Specifically, the elastic members 15 (which are elements capable of extension and retraction, preferably springs) at the top ends of the push plates 10 and the chute 9 are always in a compressed state. When the push plate 10 slides along the trajectory of the chute 9 toward its top end, the elastic member 15 is in a squeezed state and reaches its maximum squeeze value. When the push plate 10 slides along the trajectory of the chute 9 toward its bottom end, the elastic member 15 rebounds, allowing the push plate 10 to remain pressed against the high and low surfaces 13. Because of the elastic member 15, the buoyancy generated by the flotation liquid on the push plate 10 can be effectively prevented from sliding to the bottom end of the chute 9, thus avoiding any impact on the subsequent pushing of bubbles by the push plate 10.

[0038] Preferably, each of the active shaft sleeves 2 is provided with a driven wheel 16 at its top end, and a plurality of first motors 17 are evenly provided at the top end of the flotation frame 1. Each of the first motors 17 is provided with an active wheel 18 at its output end, and each of the active wheel 18 and each of the driven wheel 16 are connected one-to-one by a belt 19. Specifically, when it is necessary to drive each of the active shaft sleeves 2 to rotate synchronously, each of the first motors 17 is started synchronously to drive the active wheel 18 to rotate. The active wheel 18 and the driven wheel 16 are transmitted through the belt 19, so that the driven wheel 16 drives the active shaft sleeve 2 to rotate. When it is necessary to drive one of the shaft sleeves to rotate, it is only necessary to start the corresponding first motor 17. This is common knowledge in the art and will not be elaborated further.

[0039] Furthermore, a flotation mechanism is provided on the side wall of the flotation frame 1. The flotation mechanism is used to discharge the flotated ore body from the flotation frame 1. The flotation mechanism includes a flotation shaft 20. A second motor 21 is installed on the side wall of the flotation frame 1 on the side with the chute 9. A first synchronous wheel 22 is installed at the output end of the second motor 21. Arc-shaped through grooves 23 are provided on the side walls of the flotation frame 1 on both sides of the chute 9. The center of the arc-shaped through grooves 23 coincides with the output end of the second motor 21. Telescopic members 24 are provided on the outer walls of both sides of the flotation frame 1 at the bottom of the arc-shaped through grooves 23. A drive rod 25 is installed at the output end of the telescopic member 24. Each drive rod 25 has a straight groove 26. The length of the straight groove 26 is... The radius of the arc-shaped through groove 23 is the same as that of the flotation frame 1. The two straight grooves 26 on the two opposite side walls of the flotation frame 1 are connected by a flotation shaft 20, and the flotation shaft 20 is installed in the straight groove 26 in a sliding fit. The flotation shaft 20 passes through the arc-shaped through groove 23 and is installed in the arc-shaped through groove 23 in a sliding fit. A second synchronous wheel 27 is installed at one end of the flotation shaft 20. The first synchronous wheel 22 and the second synchronous wheel 27 are connected by a synchronous belt 28. Two symmetrical flotation plates 29 are installed on the flotation shaft 20 in each of the flotation spaces. A groove 30 is opened on the side wall of the flotation frame 1. A partition plate 31 is installed in the groove 30 in a sliding fit, and the two ends of the partition plate 31 are respectively connected to the drive rod 25. When the ore body in the flotation space floats on its surface, the second motor 21 is activated to drive the first synchronous pulley 22 to rotate. The first synchronous pulley 22 and the second synchronous pulley 27 are connected by a synchronous belt 28, which drives the second synchronous pulley 27 to rotate the flotation shaft 20. The flotation shaft 20 drives the flotation plate 29 to rotate, causing the flotation plate 29 to discharge the ore body that has floated on the surface of the flotation space and enter the flotation cavity for collection. When it is necessary to adjust the flotation height on the flotation frame 1 or to adjust the height of the flotation shaft 20 (or the flotation plate 29), the various telescopic components 24 (telescopic components 24 are telescopic components capable of linear motion, such as cylinders, hydraulic cylinders, etc.) are activated simultaneously to drive the drive rod 25 to move. The drive rod 25 drives the flotation shaft 20 to slide along the trajectory of the arc-shaped through groove 23 via the straight groove 26. This allows the flotation shaft 20 to slide simultaneously along both the arc-shaped through groove 23 and the straight groove 26 until the flotation shaft 20 and the flotation plate 29 reach the preset flotation height. Since the center of the arc-shaped through groove 23 coincides with the output end of the second motor 21, the second motor 21, the first synchronous pulley 22, and the synchronous belt 28 will not affect the transmission of the second synchronous pulley 27 and the flotation shaft 20 when the flotation shaft 20 slides along the trajectory of the arc-shaped through groove 23. At the same time, the drive rod 25 drives the partition plate 31 to slide to a suitable height within the groove 30, allowing the partition plate 31 to adjust the flotation height of the flotation frame 1 (i.e., the height of the partition plate 31 is the lowest point of the flotation frame 1).The flotation body is discharged from the flotation space through the partition 31. The heights of the flotation shaft 20, flotation plate 29, and partition 31 can be adjusted synchronously to facilitate a more stable discharge of the flotation body from the flotation space.
