Abstract
Description
Technical Field
[0001] This invention belongs to the field of mineral pulp flotation technology, specifically a pulp preparation device and method for a flotation coupling processing system. Background Technology
[0002] The flotation coupling treatment system is a separation and treatment system that combines flotation with auxiliary processes such as magnetic separation, acid leaching, and flocculation. It is widely used in mineral sorting, solid waste resource recovery and other fields. The slurry preparation device is the core pretreatment component of the system. It is mainly used to adjust the concentration of the slurry, mix flotation reagents, and homogenize the slurry so that the slurry reaches the physicochemical state required for subsequent flotation and coupling processes. In actual production, after crushing and grinding, the ore will produce a large number of fine particles (10-74 μm in diameter) and ultrafine particles (<10 μm in diameter). Due to their large specific surface area and high surface energy, these particles are easily subjected to the combined effects of van der Waals forces, electrostatic forces, and capillary forces during mixing with the liquid phase, spontaneously agglomerating into clusters. The target mineral particles inside the clusters cannot fully contact the flotation reagents, which not only reduces reagent utilization and increases operating costs, but also weakens the subsequent flotation bubble capture ability because the particle surface is not effectively modified. At the same time, the presence of agglomerates increases the viscosity of the slurry and destroys the slurry fluidity, which reduces the probability of effective collision between the target mineral and the bubble, and may also block the equipment channels of subsequent coupled processes (such as magnetic separation and gravity separation), resulting in a decrease in system processing efficiency. Existing slurry preparation devices mostly employ a traditional mixing tank combined with a simple dosing pipeline structure. The mixing intensity of a single agitator is unevenly distributed along the axial and radial directions of the tank, resulting in limited effectiveness in breaking up existing agglomerates. In fact, insufficient mixing intensity in certain areas may even lead to secondary agglomeration of fine-grained minerals. These shortcomings prevent existing devices from fundamentally solving the problem of mineral agglomeration, resulting in a persistent risk of insufficient homogenization in the prepared slurry. Therefore, this invention provides a slurry preparation device and method for a flotation coupled treatment system. Summary of the Invention

Detailed Description of Embodiments To make the technical means, creative features, objectives, and effects of this invention easier to understand, the invention is further described below in conjunction with specific embodiments. The slurry preparation device of the flotation coupling treatment system described in this embodiment of the invention includes a flotation cell 1; a treatment cell 2 is provided inside the flotation cell 1, a first island platform 7 is fixedly installed on the top of the treatment cell 2 by a support plate 3, a second island platform 8 is rotatably installed below the first island platform 7, and a crushing chamber is formed between the first island platform 7 and the second island platform 8. The crushing chamber narrows from wide to narrow, and the opening of the crushing chamber near the axis is larger than the opening away from the axis; a conveying assembly is installed inside the treatment cell 2 to send the slurry inside the treatment cell 2 into the crushing chamber; the bottom of the first island platform 7 and the top of the second island platform 8 are provided with teeth. The ore inside the treatment cell 2 is conveyed to the crushing chamber by the conveying assembly, and the second island platform 8 is rotated at the same time. Through the teeth between the first island platform 7 and the second island platform 8, the agglomerated ore can be crushed. The crushed ore will also flow out from the narrow end of the crushing chamber under the flow of slurry, thereby allowing the ore to fully contact the flotation reagent and improving the reagent utilization rate. A permeable plate 9 is fixedly installed below the first island platform 7, and a baffle plate 13 is elastically installed below the permeable plate 9. Both the permeable plate 9 and the baffle plate 13 have conical cross-sections. The permeable plate 9 has holes, while the baffle plate 13 does not. When the baffle plate 13 is in contact with the permeable plate 9, the slurry discharged from the narrow end of the crushing chamber flows onto the permeable plate 9 and accumulates there. When the baffle plate 13 slides away from the permeable plate 9, the holes on the permeable plate 9 are no longer blocked by the baffle plate 13, and the slurry accumulated on the permeable plate 9 can be discharged through the holes. A processing box 22 is installed above the permeable plate 9. A stirring shaft is fixedly installed on the outer wall of the processing box 22, and a drain port 23 is provided on the processing box 22. A reagent box 4 is fixedly installed at the top of the support plate 3, and the reagent box 4 delivers the reagent into the processing box 22 through a liquid delivery component.The ore inside the treatment tank 2 is transported to the crushing chamber by the conveying component. The second island 8 is rotated to crush the agglomerated ore. The ore flows from the narrow end of the crushing chamber into the permeable plate 9 and accumulates. At this time, the flotation reagent stored in the reagent box 4 is sent into the treatment box 22 by the liquid delivery component. Finally, the reagent is discharged into the slurry accumulated on the permeable plate 9 through the drain port 23 on the treatment box 22. At the same time, the rotation of the treatment box 22 can drive the stirring shaft to mix and react the slurry accumulated on the permeable plate 9, which greatly improves the reagent adsorption efficiency and utilization accuracy, reduces reagent waste, and allows the ore to collide precisely with the air bubbles, enhancing the flotation effect and solving the problem that the flotation process is affected by uneven reagent or agglomerate interference in the existing technology. The conveying assembly includes a horizontal conveying cylinder 12, a first auger 34, a vertical conveying cylinder 15, and a second auger 21. The vertical conveying cylinder 15 is rotatably installed inside the treatment tank 2, and a stirring rod is fixedly installed on the outer wall of the vertical conveying cylinder 15. The second auger 21 is rotatably installed inside the vertical conveying cylinder 15, and the horizontal conveying cylinder 12 is fixedly installed on the outer wall of the vertical conveying cylinder 15. The first auger 34 is rotatably installed inside the horizontal conveying cylinder 12, and one end of the second auger 21 extends into the crushing chamber. The second auger 21 is connected to the power assembly via an output shaft 5. A control gear is fixedly installed on the first auger 34 via a connecting rod. A control gear ring that meshes with the control gear is provided on the inner wall of the treatment tank 2. The power assembly includes a drive motor, a drive wheel, and a driven wheel. The output shaft 5 is connected to the driven wheel, and the drive motor is connected to the drive wheel. Therefore, when the drive motor drives the drive wheel to rotate, it can drive the driven wheel to rotate via a belt, thus causing the second auger 21 to rotate. One end of the horizontal conveyor cylinder 12 is open. When the vertical conveyor cylinder 15 rotates, it drives the horizontal conveyor cylinder 12 to rotate inside the processing tank 2. At this time, the first auger 34 can be rotated by controlling the gear and the gear ring, and the ore and slurry at the bottom of the processing tank 2 are transported to the interior of the vertical conveyor cylinder 15, and then transported to the interior of the crushing chamber by the second auger 21. A positioning ring plate 16 is fixedly installed at the top of the vertical conveyor cylinder 15, and a gap is left between the positioning ring plate 16 and the vertical conveyor cylinder 15. A blocking ring plate 17 is slidably installed inside the positioning ring plate 16 to block the gap. The vertical conveyor cylinder 15 is fixedly connected to the positioning ring plate 16. The vertical conveyor cylinder 15 can drive the positioning ring plate 16 to rotate at the same time. When the blocking ring plate 17 slides upward inside the positioning ring plate 16, the gap between the positioning ring plate 16 and the vertical conveyor cylinder 15 will be opened. At this time, the second auger 21 cannot transport the ore and slurry to the interior of the crushing chamber, and vice versa.The liquid delivery assembly includes a connecting pipe 18, a liquid delivery pipe 20, a sealing ring 19, and a delivery pipe 25. The liquid delivery pipe 20 is fixedly installed at the top of the treatment box 22, with an opening at the top. The sealing ring 19 is rotatably installed at the opening of the liquid delivery pipe 20. One end of the connecting pipe 18 passes through the sealing ring 19, and the other end is connected to the medicine box 4. The liquid delivery pipe 20 and the treatment box 22 are connected through the delivery pipe 25. The liquid delivery pipe 20 is fixedly connected to the second island platform 8, and the positioning ring plate 16 is fixedly connected to the treatment box 22. Since the liquid delivery pipe 20 is also fixedly connected to the treatment box 22, when the vertical delivery cylinder 15 rotates, it can drive the liquid delivery pipe 20 and the second island platform 8 to rotate simultaneously. Through the cooperation of the connecting pipe 18 and the sealing ring 19, the connection with the medicine box 4 is not affected when the liquid delivery pipe 20 rotates. The medicine in the medicine box 4 enters the inner cavity of the liquid delivery pipe 20 through the connecting pipe 18, and then enters the inner cavity of the treatment box 22 through the delivery pipe 25. An extension rod 26 is slidably installed at the bottom of the delivery pipe 25. A drain hole is provided on the extension rod 26. A first air ring 27 is fixedly installed at the bottom of the extension rod 26. The horizontal plane of the first air ring 27 is lower than the horizontal plane of the drain port 23. A second air ring 28 is slidably installed inside the treatment box 22. The outer wall of the second air ring 28 is in contact with the inner wall of the treatment box 22. An inlet 29 is provided at the bottom end of the treatment box 22. The bottom end of the second air ring 28 is connected to the top end of the blocking ring plate 17 through a connecting rope 30. The medicine in the medicine box 4 enters the inner cavity of the delivery pipe 20 through the connecting pipe 18, and then enters the inner cavity of the treatment box 22 through the delivery pipe 25. Subsequently, under the gravity of the medicine, the control extension rod 26 slides downward inside the delivery pipe 25 until the drain hole leaks out, sending the medicine in the inner cavity of the delivery pipe 20 into the interior of the treatment box 22. As the medicine is continuously discharged, the first air ring 27 controls the liquid level to slide upward by buoyancy, blocking the drain hole. At this point, the medicine in the inner cavity of the treatment box 22 will be ready for use. The process continues until the slurry discharged from the crushing chamber accumulates on the permeable plate 9, and the slurry floats to the surface through the inlet 29, controlling the second air ring 28 to float. When the second air ring 28 floats, the reagent in the inner cavity of the treatment box 22 can be discharged from the outlet 23 and mixed with the slurry on the permeable plate 9, which greatly improves the reagent adsorption efficiency and utilization accuracy, reduces reagent waste, and allows the ore to collide precisely with the air bubbles, enhancing the flotation effect and solving the problem of uneven reagent or agglomerate interference affecting the flotation process in existing technologies. A distance sensor 24 is installed at the top of the inner cavity of the treatment box 22. The permeable plate 9 and the baffle plate 13 are connected by an electromagnet 14, which is electrically connected to the distance sensor 24. A storage box 10 is fixedly installed at the bottom of the baffle plate 13. A movable ring 6 is rotatably installed on the inner wall of the treatment tank 2. A drain pipe 11 is fixedly installed at the bottom of the storage box 10, and the other end of the drain pipe 11 passes through the movable ring 6 and extends into the inner cavity of the flotation tank 1.When the slurry discharged from the crushing chamber accumulates on the permeable plate 9, and the slurry floats to the surface through the inlet 29 controlling the second air ring 28, the position of the second air ring 28 is monitored by the distance sensor 24. When the upward sliding distance of the second air ring 28 reaches a preset threshold, the distance sensor 24 sends a control signal to de-energize the electromagnet 14, causing the permeable plate 9 to separate from the baffle plate 13. The reagent mixed with the reagent on the permeable plate 9 then falls into the inner cavity of the storage box 10, and finally is sent to the space between the flotation tank 1 and the treatment tank 2 through the drain pipe 11 for storage. By separating from the slurry in the treatment tank 2, cross-contamination is avoided, thereby improving flotation efficiency. A toothed ring 33 is fixedly installed at the bottom of the vertical conveyor cylinder 15. A transmission gear 32 meshing with the toothed ring 33 is rotatably installed inside the treatment tank 2. One end of the output shaft 5 extends out of the vertical conveyor cylinder 15 and is fixedly installed with a rotating gear 31 meshing with the transmission gear 32. When the drive motor drives the second auger 21 to rotate, the vertical conveying cylinder 15 can be driven to rotate simultaneously through the rotating gear 31, the transmission gear 32 and the gear ring 33. Furthermore, the rotation speed of the second auger 21 is greater than that of the vertical conveying cylinder 15 through the cooperation of the rotating gear 31, the transmission gear 32 and the gear ring 33, thus ensuring the stability of the second auger 21 in conveying slurry. A slurry preparation method for a flotation coupled processing system, applicable to the slurry preparation device of the aforementioned flotation coupled processing system, includes the following steps: S1: First, the slurry in the processing tank 2 is fed into the crushing chambers of the first island platform 7 and the second island platform 8 for crushing treatment via the horizontal conveyor cylinder 12 and the vertical conveyor cylinder 15 in conjunction with the first auger 34 and the second auger 21; S2: Second, the reagent box 4 is fed into the processing box 22 through the connecting pipe 18 and the liquid delivery pipe 20, and discharged through the drain hole on the extension rod 26. The reagent in the processing box 22 is then discharged from the drain port 23 and mixed with the slurry by the second air ring 28; S3: Finally, the electromagnet 14 is controlled by the feedback signal from the distance sensor 24 to separate the permeable plate 9 from the baffle plate 13. The mixed slurry is discharged into the flotation tank 1 through the storage box 10 and the drain pipe 11 for flotation.
