Description

Technical Field

[0001] This utility model relates to the field of flotation machines, and in particular to a novel anti-overflow device for the tank of a mining flotation machine. Background Technology

[0002] In the actual operation of flotation machines, overflow of the tank has always been one of the key factors restricting their stable operation and separation effect. When the slurry level in the flotation machine is too high or the froth layer becomes abnormally thick, the slurry is very likely to overflow from the edge of the tank. This phenomenon not only causes a large amount of useful minerals to be lost with the overflow, resulting in serious resource waste, reduced metal recovery rate, and increased production costs; but also the overflowing slurry will pollute the environment around the flotation machine, increase the difficulty and cost of subsequent wastewater treatment, and pose a threat to the safety, hygiene, and environmental compliance of the production workshop.

[0003] To address the issue of tank overflow, the industry has conducted a series of technical research and improvement efforts, achieving some results. Currently, common overflow prevention measures mainly include mechanical baffles. These baffles, installed at the edge of the tank with fixed or adjustable height baffles, attempt to prevent slurry overflow. However, this type of device has a simple structure and limited function, making it difficult to adapt to the complex operating conditions during flotation. Because the slurry level inside the flotation machine is affected by various factors such as feed rate, reagent dosage, and aeration rate, it fluctuates frequently and significantly. Mechanical baffles cannot dynamically adjust according to the actual slurry level, often affecting normal slurry circulation and froth layer stability when the slurry level is low, while failing to effectively prevent overflow when the slurry level is too high, resulting in poor overflow prevention performance.

[0004] In practical applications, the liquid level is maintained at a high level for an extended period to clean the froth layer. During flotation, the froth layer is an enriched phase formed by the combination of mineral particles and air bubbles, and its thickness and stability directly affect the flotation effect. When the ore is complex, such as containing a large amount of clay minerals or having a high oxidation rate, the froth layer tends to become viscous and dense, even exhibiting a "trapping" phenomenon, where a large amount of gangue minerals are trapped within the froth and difficult to separate. To effectively clean this type of froth layer and reduce gangue mineral contamination of the concentrate, operators often increase the liquid level to increase the depth and agitation intensity of the froth layer, prompting the froth to break and the mineral particles to redistribute into the slurry for secondary separation. However, this viscous froth can cause adhesion and scaling of the slurry on the inner wall of the tank, creating cleaning dead zones and thus affecting subsequent flotation.

[0005] During the flotation process, fine minerals and reagent residues in the slurry gradually deposit on the inner wall of the tank, forming a scale layer. The presence of the scale layer not only reduces the effective volume of the tank and decreases the processing capacity of the flotation machine, but also changes the smoothness of the inner wall of the tank, affecting the flow state of the slurry and the dispersion effect of bubbles, thereby reducing the flotation separation efficiency.

[0006] Currently, the cleaning of the inner walls of the flotation tank mainly relies on regular manual cleaning. Manual cleaning is labor-intensive, inefficient, and it's difficult to guarantee timely cleaning, especially in large flotation machines where operators cannot easily enter the tank for cleaning, posing significant safety hazards.

[0007] Therefore, it is necessary to provide a new type of anti-overflow device for the flotation tank of a mining flotation machine to solve the problems of scaling on the inner wall of the tank and overflow. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Please refer to the following: Figures 1 to 7 ,in, Figure 1 A schematic diagram of the overall structure of the novel anti-overflow device for the mining flotation machine provided by this utility model; Figure 2 A schematic cross-sectional view of the overall structure of the novel anti-overflow device for the mining flotation machine provided by this utility model; Figure 3 This is a schematic diagram of the bottom structure of the flotation machine; Figure 4 This is a schematic diagram of the toggle assembly. Figure 5 for Figure 4 Enlarged view of point A in the middle; Figure 6 A structural diagram of the cleaning component; Figure 7 This is a schematic diagram of the limit component.

[0033] In some embodiments, such as Figures 1 to 7 As shown, it includes a flotation assembly located on top of the bottom plate 1. The width of the flotation assembly is adjustable, and a cleaning assembly for cleaning the inner wall of the tank is provided on top of the flotation assembly.

[0034] The cleaning assembly includes a drive unit installed on top of the flotation assembly, a telescopic plate 25, an arc-shaped scraper 26, and two inclined plates 27. The middle part of the telescopic plate 25 is fixedly connected to the output end of the drive unit. The arc-shaped scraper 26 is fixed on one side of the telescopic plate 25, and one end of the arc-shaped scraper 26 is in contact with the inner wall of the tank to remove the slurry, reagent residues, and scale layer attached to the inner wall of the tank. The two inclined plates 27 are respectively rotatably set at both ends of the telescopic plate 25. One side of the two inclined plates 27 is in contact with the corresponding side wall of the tank. The top of the telescopic plate 25 is also provided with a limiting assembly for limiting the angle of the inclined plates 27.

[0035] Among them, telescopic plate 25 consists of telescopic plate A and two telescopic plates B. The two telescopic plates A extend and retract at both ends of telescopic plate B, and the output end of the driving component is fixedly connected to the middle of telescopic plate A.

[0036] Among them, the two rotatable inclined plates 27 are tightly fitted with the side wall of the tank under the action of the limiting component, which can effectively clean the side wall at different inclination angles, further expanding the cleaning range and avoiding the dead angle problem of traditional cleaning methods.

[0037] Among them, the top of the telescopic plate 25 has two limiting holes 251, which are respectively opened on the top of the two telescopic plates 2B. The end of the connecting post 28 near the telescopic plate 25 is provided with multiple equally spaced insertion holes 281. The design of multiple equally spaced insertion holes 281 enables the connecting post 28 to be fixed at various angles or positions when it is in conjunction with the limiting components, providing a basis for the flexible adjustment of the angle of the inclined plate 27. There are two limiting components, and one end of the limiting components is inserted into the insertion hole 281.

[0038] Both limiting components include a telescopic plate 2 5. A top plate 51 is fixed to the top of the telescopic plate 2 5. A pull ring 52 is fixed to the top of the top plate 51. A limiting rod 53 is fixed to the bottom of the top plate 51. The size of the limiting rod 53 matches the size of the insertion hole 281. One end of the limiting rod 53 is inserted into the insertion hole 281. By inserting it into the insertion hole 281 at different positions, the position of the connecting column 28 is fixed, thereby limiting the angle of the inclined plate 27.

[0039] Specifically, by setting up a cleaning component for cleaning the inner wall of the tank, the drive unit moves the telescopic plate 25 up and down, and the arc-shaped scraper 26 fits tightly against the inner wall of the tank to scrape and clean the main wall surface of the tank. At the same time, two inclined plates 27 are rotatably set at both ends of the telescopic plate 25 and fit against the corresponding side walls of the tank. The angle of the inclined plates 27 is limited by the limiting component, which can clean the side walls of the tank, improving cleaning efficiency and effect. By periodically and automatically cleaning the inner wall of the tank, the scale layer is removed in time, thereby ensuring smooth slurry flow and uniform dispersion of bubbles, effectively improving flotation separation efficiency, increasing concentrate grade, and reducing tailings grade. This solves the problems of existing tank inner wall cleaning mainly relying on manual periodic cleaning, which has problems such as high labor intensity, low efficiency, difficulty in ensuring timely cleaning, and safety hazards caused by operators entering the tank for cleaning.

[0040] In some embodiments, such as Figures 1 to 3As shown, the top of the base plate 1 is provided with a groove 11 and a limiting groove 12. The groove 11 is located on one side of the limiting groove 12. The bottom of the flotation assembly slides on the bottom wall of the limiting groove 12. The top of the base plate 1 is respectively fixed with a support rod 2 and a fixing plate 22. The limiting groove 12 is located between the support rod 2 and the fixing plate 22. A fixing plate 21 is fixed on one side of the support rod 2. A sliding groove 211 is provided on the inner wall of the fixing plate 21.

[0041] The flotation assembly includes a motor 13 and two side plates 14. The motor 13 is fixed in a groove 11. The rotor of the motor 13 passes through the groove 11 and is fixed with a bidirectional lead screw 131. The other end of the bidirectional lead screw 131 rotates on the inner wall of the limiting groove 12. The two side plates 14 are threaded to the surface of the bidirectional lead screw 131 respectively. The bottom of the two side plates 14 slides on the inner wall of the limiting groove 12. The surface of the two side plates 14 is provided with a sliding groove 141. One end of the two side plates 14 slides on the surface of the fixing plate 22 through the sliding groove 141. A limiting block 142 is also fixed on the side of the two side plates 14 away from the fixing plate 22. The other end of the two side plates 14 slides on the inner wall of the sliding groove 211 through the two limiting blocks 142 respectively.

[0042] Rubber sealing strips are fixed at the positions where the two side plates 14 fit into the limiting groove 12, the fixing plate 11, and the fixing plate 22.

[0043] The tank is mainly composed of two side plates, a first fixed plate, and a second fixed plate. The scale on the inner wall of the tank is cleaned, that is, the inner walls of the two side plates 14, the first fixed plate 21, and the second fixed plate 22 are cleaned.

[0044] Specifically, the width of the flotation assembly is adjustable. During use, the drive motor 13 drives the bidirectional lead screw 131 to rotate. Since the two side plates 14 are located at the two threaded ends of the bidirectional lead screw 131, the bottom of the two side plates 14 slides on the inner wall of the limiting groove 12. One end of the two side plates 14 slides on the surface of the fixed plate 22 through the sliding groove 141, and the other end of the two side plates 14 slides on the inner wall of the sliding groove 211 through the two limiting blocks 142. At this time, under the rotation of the bidirectional lead screw 131, the two side plates 14 are driven to move closer to the middle or further away, thereby changing the liquid level of the slurry in the tank.

[0045] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, a U-shaped plate 23 is fixed to the top of the fixed plate 21, and one end of the driving component is fixed to the inner wall of the U-shaped plate 23. The driving component includes a hydraulic rod 24, and the two ends of the hydraulic rod 24 are fixedly connected to the inner wall of the U-shaped plate 23 and the middle part of the telescopic plate 25, respectively.

[0046] During cleaning, the hydraulic rod 24 drives the telescopic plate 25 to move up and down, which in turn drives the arc scraper 26 and the inclined plate 27 to clean the inner walls of the fixed plate 21 and the two side plates 14 respectively.

[0047] Two fixing plates 221 are also fixed on the side of the fixing plate 2 away from the support rod 2. The two side plates 14 are located between the two fixing plates 221 respectively. A toggle assembly is also provided between the two fixing plates 221.

[0048] The actuating assembly includes a motor 4, a telescopic slot frame 42, a cleaning rack 43, and two actuating plates 44. The motor 4 is fixed to the outside of one of the fixing plates 221. The rotor of the motor 4 passes through the surface of one of the fixing plates 221 and is fixed with a rotating rod 31. The other end of the rotating rod 31 is fixed to the inside of the other fixing plate 221. The cleaning rack 43 is fixedly connected to the surface of the rotating rod 31. The two ends of the telescopic slot frame 42 are respectively fixed between the two fixing plates 221. One side of the telescopic slot frame 42 is connected to the fixing plate 221. The telescopic slot frame 42 is fixedly connected to the side away from the fixed plate 21. It is located below the cleaning frame 43. Two actuating plates 44 are rotatably set on both sides of the cleaning frame 43. Two rotating shafts 45 are fixed on the inner wall of the cleaning frame 43. The two actuating plates 44 rotate on both sides of the cleaning frame 43 through the two rotating shafts 45 respectively. The outer side of the cleaning frame 43 is also provided with a knob 46 for adjusting the rotation angle of the actuating plates 44. There are two knobs 46. The knobs 46 are preferably screws, which use a pressing method to fix the angle of the actuating plates 44.

[0049] Specifically, in use, first turn the two knobs 46 to limit the angle of the two actuating plates 44. After adjusting the angle of the actuating plates 44, start the motor 3 4. The rotor of the motor 3 4 starts to rotate, driving the rotating rod 31, which is fixedly connected to it, to rotate synchronously. Since the cleaning frame 43 is fixedly connected to the surface of the rotating rod 31, the rotation of the rotating rod 31 directly drives the cleaning frame 43 to rotate, which in turn drives the actuating plates 44 installed on both sides of the cleaning frame 43 to rotate together. The rotating actuating plates 44 agitate the slurry and foam in the area of ​​the fixed plate 22 away from the fixed plate 21. The agitation of the actuating plates 44 breaks the original stable state of the foam layer, enhances the fluidity of the foam, and promotes the foam to move towards the preset discharge area of ​​the tank, ultimately discharging the foam from the tank. This prevents the foam from accumulating excessively in the tank and causing overflow problems, while maintaining the dynamic balance of the slurry and foam layer in the tank, ensuring the stable operation of the flotation process.

[0050] Furthermore, when adjusting the distance between the two side plates 14, i.e. changing the liquid level of the slurry in the tank, the telescopic tank frame 42 will also extend and retract accordingly, and the telescopic tank frame 42 plays a role in guiding foam, making it easier for foam to be discharged out of the tank.

[0051] In some embodiments, such as Figures 1 to 2 As shown, a stirring assembly is also provided at the top of the support rod 2;

[0052] The stirring assembly includes a second motor 3, which is fixed to the top of the support rod 2. The rotor of the second motor 3 passes through the surface of the support rod 2 and is fixed with a rotating rod 31. The other end of the rotating rod 31 is located between two side plates 14, and multiple equally spaced stirring blades 32 are arranged around the other end of the rotating rod 31.

[0053] Specifically, during use, the second motor 3 drives the rotating rod 31 to rotate. Multiple stirring blades 32 fixed on the surface of the rotating rod 31 rotate with the rotation of the rotating rod 31, thereby stirring the slurry in the tank. In the flotation process, various flotation reagents, such as collectors and frothers, are usually added to the slurry. The rotating stirring action of the stirring blades 32 can quickly and evenly disperse the reagents in the slurry, breaking the uneven concentration of the reagents in local areas, and allowing the reagents to fully contact the mineral particles. For example, the collector can more effectively adsorb onto the surface of the target mineral particles, improve the adhesion between the mineral particles and the air bubbles, thereby enhancing the flotation effect and increasing the recovery rate of the target mineral.

[0054] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
