Description

Technical Field

[0001] The present invention relates to the field of flotation technology, and in particular to a flotation system and a flow stabilizing structure. Background Art

[0002] The flotation machine's flow stabilization device is a crucial component for maintaining a stable flow field during the flotation process. It's used to stabilize and disperse the slurry that emerges from the vortex after vigorous stirring by the stirring mechanism, ensuring uniform dispersion within the flotation cell and allowing it to float upward. However, if the mineral properties are poor, the proportion of coarse particles is high, or coarse particles occur before flotation, the bubbles carrying the minerals will often burst prematurely before reaching the foam layer or collection during the flotation process, causing the minerals to fall back, impacting concentrate yield and production indicators, increasing production load, and causing economic losses.

[0003] The existing technology for flotation machine flow stabilization devices is almost of the same type. The conventional structure is composed of a false bottom and a guide plate, which cannot play a positive role in the flotation time in a single flotation tank and the problem of coping with sudden changes in flotation feed. As a result, the problem of successful enrichment before the foam bursts cannot be solved during the flotation process. Summary of the Invention

[0013] Optionally, there is an angle between the two side edges of the guide plate perpendicular to the axis of the slurry suction base plate and the radial direction of the slurry suction base plate, and the upper guide plate and the lower guide plate both have a second straight line segment and a second curved line segment, one end of the second curved line segment is close to the edge of the slurry suction base plate, and the second straight line segment is connected to the other end of the second curved line segment.

[0014] A flotation system employs a flow stabilization structure.

[0015] The working principle and beneficial effects of the present invention are: To address the problem of flotation froth not being able to be enriched smoothly due to material differences, this invention incorporates an angle-adjustable guide plate. By adjusting the angle of the guide plate, the flow pattern of the fluid ejected after stirring by the agitator can be controlled. This alters the trajectory of the slurry within the flotation cylinder, increasing or decreasing the flotation time based on different slurry properties, ensuring the timely collection and removal of flotation froth, and improving the controllability and variability of flotation efficiency.

[0016] The working principle of the present invention is that the angle of the guide plate can be adjusted by the pull rod. The guide plate can be in a horizontal state, tilted upward or downward at the end away from the stirring element. The lowest angle of the guide plate is level with the slurry suction bottom plate, and the slurry suction bottom plate has an inclination angle of 10° horizontally downward. When the guide plate angle is set to 0° (i.e. horizontal), the slurry emitted from the stirring area is vertically injected into the flotation tube wall plate, and the slurry presents two component velocities, vertically upward and vertically downward. The vertically upward fluid is transported to the foam layer through the foam to collect the product; when the guide plate angle is set to greater than 0° (i.e. tilted upward), the slurry emitted from the stirring area is injected into the flotation tube wall plate at a certain angle, and the slurry will produce a fluid that is vertically upward and has a certain inclination to the vertical direction. The fluid with an inclination has a shorter floating path in the slurry, which reduces the flotation time, and finally floats near the stirring shaft for foam collection. The foam generated in this area The layers gradually converge toward the periphery of the flotation cell to achieve the purpose of product collection; when the angle of the guide plate is set to less than 0° (i.e., tilted downward), part of the slurry emitted from the stirring area is injected into the flotation cell wall in a horizontal direction, and part of it is diverted by the guide plate to form a downward-inclined fluid. This fluid collides with the flotation cell wall to produce a vertically downward and downward-inclined fluid. This part of the fluid enters the bottom of the slurry along with the feed slurry, thereby achieving a secondary mineralization effect; by adjusting the angle of the guide plate, the flotation process time of the slurry is adjusted and the problem of coarse-grained foam enrichment is dealt with, thereby achieving the optimization effect of flotation conditions.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Example 1 Reference Figure 1~Figure 2, which is the first embodiment of the present invention, proposes a flow stabilizing structure for adjusting the time of slurry flotation, including a slurry suction bottom plate 1, which is used to be set in the flotation cylinder 2, and the slurry suction bottom plate 1 has a slurry inlet 11; the stirring member 3 is rotatably arranged relative to the slurry suction bottom plate 1, and the stirring member 3 has a stirring portion 301, and the stirring portion 301 is located above the slurry inlet 11. An injection gap 302 is provided between the stirring member 3 and the slurry suction bottom plate 1, and the slurry inlet 11 leads to the injection gap 302; one end of the guide plate 4 is swingably set on the slurry suction bottom plate 1, and the guide plate 4 adjusts the angle of the slurry ejected from the injection gap 302 after swinging. There are multiple guide plates 4, and the multiple guide plates 4 are distributed at intervals along the circumference of the slurry inlet 11; one end of the pull rod 5 is set on the guide plate 4, and the pull rod 5 is used to drive the guide plate 4 to swing.

[0024] To address the problem of flotation froth not being able to be smoothly enriched due to material differences, an angle-adjustable guide plate 4 has been designed. By adjusting the angle of the guide plate 4, the flow pattern of the fluid ejected from the agitator 3 after stirring can be controlled. This changes the trajectory of the slurry within the flotation drum 2, increasing or decreasing the flotation time based on different slurry properties, ensuring the timely collection and removal of flotation froth, and improving the controllability and variability of flotation efficiency.

[0025] Specifically, the angle of the guide plate 4 can be adjusted by the pull rod 5. The guide plate 4 can be in a horizontal state, tilted upward or downward at the end away from the stirring member 3. The lowest angle of the guide plate 4 is flush with the slurry suction bottom plate 1, and the slurry suction bottom plate 1 has an inclination angle of 10° from the horizontal downward. When the angle of the guide plate 4 is set to 0° (i.e. horizontal), the slurry emitted from the stirring area is vertically injected into the wall of the flotation cylinder 2, and the slurry presents two component velocities, vertically upward and vertically downward. The vertically upward fluid is transported to the foam layer through the foam to collect the product; when the angle of the guide plate 4 is set to greater than 0° (i.e. tilted upward), the slurry emitted from the stirring area is injected into the wall of the flotation cylinder 2 at a certain angle, and the slurry will produce a fluid that is vertically upward and has a certain inclination to the vertical direction. This fluid with an inclination reduces the flotation time in the slurry, and finally floats up near the stirring shaft 31 for foam collection. The foam layer generated in this area gradually... The slurry gradually flows toward the periphery of the flotation cell to achieve the purpose of product collection; when the angle of the guide plate 4 is set to less than 0° (i.e., tilted downward), part of the slurry emitted from the stirring area is injected into the flotation cell wall in a horizontal direction, and part of it is diverted by the guide plate 4 to form a downward-dipping fluid. This fluid collides with the flotation cell wall to produce a vertically downward and downward-dipping fluid. This part of the fluid enters the bottom of the slurry along with the feed slurry, thereby achieving a secondary mineralization effect; by adjusting the angle of the guide plate 4, the flotation process time of the slurry is adjusted and the problem of coarse particle foam enrichment is addressed, thereby achieving the optimization effect of the flotation conditions.

[0026] Example 2 Reference Figure 1~Figure 2、 Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the stirring member 3 includes a stirring shaft 31, which is rotatably arranged relative to the slurry suction base plate 1; the impeller 32 is arranged at one end of the stirring shaft 31 close to the slurry suction base plate 1, and the impeller 32 is the stirring part 301; the isolation tube 33 is arranged on the slurry suction base plate 1, and the impeller 32 is located in the isolation tube 33, a stirring zone is formed between the impeller 32 and the isolation tube 33, and an ejection gap 302 is formed between the lower end of the isolation tube 33 and the slurry suction base plate 1.

[0027] A slurry suction zone is formed between the lower side of the slurry suction bottom plate 1 and the flotation cylinder 2, a flow adjustment zone is formed between the isolation cylinder 33, the upper side of the slurry suction bottom plate 1 and the flotation cylinder 2, and a foam separation zone is formed in the flotation cylinder 2 located on the upper side of the isolation cylinder 33.

[0028] It also includes a lower guide plate 6, which is arranged on the lower surface of the slurry suction base plate 1. There are multiple lower guide plates 6, which are distributed at intervals along the circumference of the slurry inlet 11, and a diversion channel 61 is formed between two adjacent lower guide plates 6.

[0029] In this embodiment, the impeller 32 is designed with a certain curvature and number of blades, for example, six curved blades are used. The isolation cylinder 33 is a cylindrical structure, and a suitable width is reserved between the two as a stirring zone. When the stirring shaft 31 drives the impeller 32 to rotate at high speed, the slurry is vigorously stirred in the stirring zone formed by the isolation cylinder 33 and the impeller 32, forming a uniform flow state, and then flows out through the ejection gap 302. The combination of the stirring shaft 31 and the impeller 32 forms an efficient stirring system that can vigorously stir the slurry so that the different components in the slurry are fully mixed and contacted with the flotation reagent. The setting of the isolation cylinder 33, on the one hand, limits the stirring area, making the stirring more concentrated and effective, and on the other hand, ensures the stability of the ejection gap 302, so that the slurry can enter the guide plate 4 from the stirring zone at a stable flow rate and state, which helps to improve the stability and reliability of the entire flotation process.

[0030] The shape of the lower guide vane 6 is a combination of curves and straight lines. As the slurry flows from the suction zone into the agitation zone, the lower guide vane 6 guides the slurry along the diversion channel 61. This prevents the slurry from forming vortices or localized accumulations on the underside of the suction plate 1, allowing the slurry to be evenly distributed to various locations before entering the agitation zone. The provision of the lower guide vane 6 effectively guides and distributes the slurry flow below the suction plate 1, preventing turbulent slurry flow and ensuring that the slurry can evenly enter subsequent agitation and other processing steps. This improves the uniformity and stability of the slurry treatment provided by the entire flow stabilization structure, thereby enhancing the flotation effect.

[0031] Example 3 Reference Figure 3, which is the third embodiment of the present invention. This embodiment is based on the second embodiment and is additionally provided with an upper guide plate 7. The upper guide plate 7 is arranged on the upper surface of the slurry suction base plate 1. There are multiple upper guide plates 7. The multiple upper guide plates 7 are distributed along the circumference of the isolation tube 33 at intervals, and a guide plate 4 is distributed between two adjacent upper guide plates 7.

[0032] In this embodiment, the upper guide plate 7 also has a structure with curved and straight segments. After the slurry flows out of the stirring zone through the ejection gap 302, the upper guide plate 7 guides the slurry again. Depending on the different angles of the guide plate 4, the slurry flows along a predetermined path to the flow pattern adjustment zone and then into the foam separation zone, or partially flows back into the slurry absorption zone. This facilitates the formation of a stable foam layer in the foam separation zone, improving the efficiency of the combination of the target substance and the foam.

[0033] The upper guide vane 7 further guides and organizes the slurry flowing out of the ejection gap 302, and in conjunction with the lower guide vane 6, comprehensively optimizes the entire slurry flow path. This design helps improve the flow stability and directionality of the slurry within the flotation cylinder 2, making the flotation process more orderly and improving the efficiency and quality of flotation. In particular, it can enhance the stability of the foam and the enrichment of the target substance during the froth separation process.

[0034] Example 4 Reference Figure 1 、 Figure 2 、 Figure 4 , which is the fourth embodiment of the present invention, is based on the second embodiment and is additionally provided with a side plate 8 , which has multiple side plates 8 , and is provided on both sides of the guide plate 4 .

[0035] In this embodiment, side plates 8 are fixed to both sides of each guide plate 4 by welding or bolting. During the swinging of the guide plate 4, the side plates 8 restrict the slurry to flow only through the front of the guide plate 4, preventing slurry leakage from the side or turbulence. This ensures that the guide plate 4 precisely controls the slurry flow direction, allowing the slurry to be ejected at a set angle, thereby improving the overall flow stabilization structure's ability to handle high-concentration, high-flow slurries. When handling various types of slurries, especially high-concentration, high-viscosity slurries, it effectively prevents slurry leakage and turbulence, ensuring that the entire flotation process proceeds according to the predetermined flow pattern, thereby improving the reliability and adaptability of the flotation system.

[0036] Example 5 Reference Figure 1 , which is the fifth embodiment of the present invention. This embodiment is different from the third or fourth embodiment in that one end of the pull rod 5 is hinged to the guide plate 4, and also includes a mounting block 9, which is slidably set on the stirring shaft 31; the connecting block 10 is relatively rotatably set on the mounting block 9, and the other end of the pull rod 5 is hingedly set on the connecting block 10.

[0037] In this embodiment, the pull rod 5 is hinged to the deflector 4 via a ball joint. The mounting block 9 is a metal block with a slideway that can slide up and down along the agitator shaft 31. Sliding the mounting block 9 allows the position of the mounting block 9 on the agitator shaft 31 to be adjusted. To adjust the angle of the deflector 4, the mounting block 9 is pushed to slide on the agitator shaft 31, causing the connecting block 10 to slide with it, thereby pulling the pull rod 5 to cause the deflector 4 to swing. During the rotation of the agitator shaft 31, the mounting block 9 and the connecting block 10 rotate relative to each other, allowing the agitator shaft 31 to idle within the connecting block 10, preventing mutual interference between the two. In an automated flotation production line, this structure can precisely control the angle of the deflector 4 based on a preset program and sensor feedback. When processing different batches of ore slurry, the angle of the deflector 4 is automatically adjusted according to the composition and properties of the ore to optimize the flotation time. The ability to precisely adjust the angle of the deflector 4 based on different flotation process requirements and slurry characteristics improves the automation and adaptability of the flow stabilization structure, reduces manual intervention, and improves the efficiency and stability of flotation production.

[0038] Example 6 Reference Figure 1 、 Figure 2 、 Figure 4 , which is the sixth embodiment of the present invention. This embodiment is different from the fourth embodiment in that the two sides of the guide plate 4 perpendicular to the axis of the slurry suction base plate 1 have an angle with the radial direction of the slurry suction base plate 1, and the lower guide plate 6 has a first straight segment 601 and a first curved segment 602. One end of the first curved segment 602 is close to the edge of the slurry suction base plate 1, and the first straight segment 601 is connected to the other end of the first curved segment 602.

[0039] In this embodiment, the two sides of the guide plate 4 perpendicular to the axis of the slurry suction base plate 1 are designed to form a certain angle with the radial direction of the slurry suction base plate 1, and the side plates 8 have the same direction as the two sides of the guide plate 4. This structure of the guide plate 4 and the side plates 8 reduces the weakening of the slurry ejected from the ejection gap 302, so that the guide plate 4 can better play a guiding role. During the slurry flow process, the side shape of the guide plate 4 and the shape of the lower guide plate 6 cooperate with each other to guide the slurry to gradually change its flow direction. On the one hand, it can generate beneficial shear force on the slurry, which is conducive to the dispersion and treatment of impurities. On the other hand, it can reduce the resistance of the slurry flow, allowing the slurry to enter the subsequent area more smoothly, and the flow in the stabilizing structure is smoother and more efficient, thereby improving the processing capacity and adaptability of the entire flotation process for different types of slurries.

[0040] Example 7 Reference Figure 3, which is the seventh embodiment of the present invention. This embodiment is different from the third embodiment in that the two sides of the guide plate 4 perpendicular to the axis of the slurry suction base plate 1 have an angle with the radial direction of the slurry suction base plate 1, and the upper guide plate 7 and the lower guide plate 6 both have a second straight segment 603 and a second curved segment 604. One end of the second curved segment 604 is close to the edge of the slurry suction base plate 1, and the second straight segment 603 is connected to the other end of the second curved segment 604.

[0041] In this embodiment, the two sides of the guide plate 4, perpendicular to the axis of the slurry suction base plate 1, are designed to form a certain angle with the radial direction of the slurry suction base plate 1. The shapes of the upper guide plate 7 and the lower guide plate 6 match the shape of the guide plate, and each has a second straight segment 603 and a second curved segment. As the slurry flows from the slurry suction zone through the stirring zone and then to the foam separation zone, the guide plate 4, the upper guide plate 7, and the lower guide plate 6 work together. The guide plate 4 adjusts the slurry ejection angle, and the upper guide plate 7 and the lower guide plate 6 guide and shape the slurry at different heights, forming a stable and orderly flow pattern within the entire flotation cylinder 2, improving the contact efficiency between the target substance and the flotation reagent and the foam separation effect.

[0042] The shapes of the guide plate 4, upper guide vane 7, and lower guide vane 6 are designed to work together to guide the flow while reducing resistance to the slurry flow. This improves the stability and orderliness of the slurry flow throughout the flotation process, enhances the contact between the target substance and the flotation reagent, and improves the efficiency and quality of foam separation, thereby enhancing the overall flotation system's processing capacity and flotation effect for complex slurries.

[0043] Example 8 As an eighth embodiment of the present invention, a flotation system is proposed, which uses a flow stabilization structure.

[0044] In this embodiment, the flow stabilization structure is installed in the flotation drum 2 in the flotation system. During flotation operations, the flotation system can optimize flotation process parameters by adjusting the angle of the guide plate 4 in the flow stabilization structure and the rotation speed of the agitator 3, based on factors such as the type and grade of the ore, thereby improving the recovery rate of useful minerals in the ore and the quality of the concentrate. This system has the advantages of precise control of the slurry flotation time and comprehensive optimization of the slurry flow state. It can adapt to the flotation requirements of slurries of different types and properties, improve the stability, reliability, and efficiency of the flotation process, reduce production costs, and improve product quality. It has broad application prospects in flotation processes in multiple industries such as mineral processing, chemical industry, and papermaking.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
