Description

Technical Field

[0001] This utility model relates to the technical field of ilmenite flotation equipment, and in particular to an ilmenite slurry flow rate regulator when adding flotation collectors. Background Technology

[0002] Flotation is an important mineral separation technology that utilizes the differences in the physicochemical properties of mineral surfaces. By adding specific reagents, the target mineral adheres to air bubbles and floats to the surface, separating it from gangue minerals. In the mining industry, with the gradual depletion of high-quality mineral resources and the increase in complex and difficult-to-process ores, flotation technology is crucial for improving resource utilization and achieving efficient recovery of mineral resources.

[0003] During the flotation of ilmenite, the similar surface properties of the target mineral and gangue minerals lead to finer particle size, lower grade, and easier mudding and mixing, increasing the difficulty of separation. At this point, the ilmenite flotation pulp flow rate regulator plays a crucial role, precisely controlling the pulp flow rate to ensure uniform dispersion of flotation reagents. The flotation machine mainly consists of components such as a stirring device and an aeration device. These components work together to complete the addition of flotation collectors and the mineral flotation process, achieving effective separation of ilmenite from impurities.

[0004] In existing technologies, precise control of the ilmenite pulp flow rate during flotation operations is quite difficult, making it impossible to guarantee the accuracy and stability of flow rate control. This results in flow rate fluctuations, which are difficult to fully meet the extremely strict requirements of the flotation process for pulp flow rate, thus limiting the improvement of flotation effect to a certain extent. To address this issue, an ilmenite pulp flow rate regulator for adding flotation collectors is proposed. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides a flow rate regulator for ilmenite slurry when adding flotation collector, including a mixing buffer tank 1. The mixing buffer tank 1 serves to contain and initially buffer the slurry. The mixing buffer tank 1 is rotatably connected to a buffer mixing mechanism inside, and a flow rate regulating mechanism is fixedly connected to the outside of the mixing buffer tank 1.

[0035] The flow regulation mechanism includes a regulating shell 15, which protects the internal flow rate control component and control drive component. A slurry guide pipe 14 is fixedly connected to the outside of the regulating shell 15. The slurry guide pipe 14 is a channel connecting the mixing buffer tank 1 and the flow rate control component, and can guide the initially mixed ilmenite slurry to the subsequent processing mechanism. The outside of the slurry guide pipe 14 is fixedly connected to the outside of the mixing buffer tank 1. The flow rate control component is rotatably connected to the inside of the regulating shell 15, and the control drive component is fixedly connected to the outside of the regulating shell 15.

[0036] The flow rate control component includes an opening and closing valve plate 23, which is the core component of the flow rate control component. The flow rate of the slurry is adjusted by changing the opening and closing angle and the channel size of the opening and closing valve plate 23. A rotating column 24 is fixedly connected to the outside of the slurry guide pipe 14. The rotating column 24 is the support shaft for the rotation of the opening and closing valve plate 23. The inside of the opening and closing valve plate 23 is rotatably connected to the outside of the rotating column 24. An opening and closing connecting block 22 is fixedly connected to the outside of the opening and closing valve plate 23. The opening and closing connecting block 22 can connect the opening and closing valve plate 23 and subsequent components.

[0037] A gear disk 18 is rotatably connected to the inner side of the regulating shell 15. The rotation of the gear disk 18 drives the opening and closing connecting rod 21 to rotate, which in turn drives the opening and closing valve plate 23 to rotate, adjusting the size of the pipe opening and achieving precise adjustment of the flow rate of the ilmenite slurry. A fixing column 20 is fixedly connected to the inner side of the regulating shell 15. The fixing column 20 provides support and positioning for the rotation of the gear disk 18. Multiple arc-shaped grooves 19 are opened on the outer side of the gear disk 18. The arc-shaped grooves 19 play a guiding and limiting role, limiting the rotation range and angle of the gear disk 18 and preventing the opening and closing valve plate 23 from over-opening and closing, which would lead to sealing failure. The outer side of the gear disk 18 is slidably connected to the inner side of the arc-shaped grooves 19. The outer side of the gear disk 18 is rotatably connected to the opening and closing connecting rod 21. The opening and closing connecting rod 21 transmits the rotation of the gear disk 18 to the opening and closing valve plate 23, realizing the rotation control of the opening and closing valve plate 23. The outer side of the opening and closing connecting rod 21 is rotatably connected to the inner side of the opening and closing connecting block 22.

[0038] A sealing strip 25 is fixedly connected to the outside of the opening and closing valve plate 23. When the opening and closing valve plate 23 is closed, the sealing strip 25 fills the groove on the outside of the other opening and closing valve plate 23, which can effectively prevent slurry leakage and ensure the accuracy and stability of flow rate control during flow regulation. The outside of the sealing strip 25 can be slidably connected to the groove on the outside of the other opening and closing valve plate 23.

[0039] The control drive assembly includes an opening and closing control motor 16, which is the power source of the control drive assembly. The outer side of the opening and closing control motor 16 is fixedly connected to the outer side of the regulating shell 15. A drive gear 17 is fixedly connected to the outer side of the output end of the opening and closing control motor 16. When the opening and closing control motor 16 rotates, the drive gear 17 will drive the gear disk 18 to rotate, and then control the rotation of the opening and closing valve plate 23 through components such as the opening and closing connecting rod 21, so as to realize the regulation of the slurry flow. The outer side of the drive gear 17 is rotatably connected to the inside of the regulating shell 15, and the drive gear 17 and the gear disk 18 are meshed with each other.

[0040] A fixing plate 8 is fixedly connected to the top of the mixing buffer tank 1. The fixing plate 8 is used to support and fix the collector aid tank 9 and the aid nozzle 10. The collector aid tank 9 is fixedly connected to the top of the fixing plate 8. The collector aid tank 9 is used to store flotation collectors and other aids. It is equipped with a liquid level sensor and other devices to monitor the remaining amount of aids. Multiple aid nozzles 10 are fixedly connected to the bottom of the fixing plate 8. The aid nozzles 10 spray the aids in the collector aid tank evenly into the slurry in the mixing buffer tank 1. The collector aid tank 9 and the aid nozzles 10 are connected by a hose.

[0041] Reference Figures 1 to 3The buffer mixing mechanism includes an energy-dissipating orifice plate 2, which is one of the key components of the buffer mixing mechanism. Its main function is to eliminate the kinetic energy when the slurry flows in, so that the slurry flow rate is more stable and it is convenient to control the slurry flow rate in the future. Multiple energy-dissipating bubble holes 3 are opened on the outer side of the energy-dissipating orifice plate 2. When the slurry flows through the energy-dissipating orifice plate 2, the slurry flow rate will be reduced due to the obstruction of the holes. At the same time, some slurry will form tiny bubbles. These bubbles help the slurry and flotation collector mix better. A buffer control component is slidably connected to the inner side of the energy-dissipating orifice plate 2. A feeding and mixing component is rotatably connected inside the mixing buffer tank 1. The buffer control component includes an adjusting rod 4. By pulling the adjusting rod 4, the position or state of the energy-dissipating orifice plate 2 can be adjusted, thereby changing the flow rate and flow of the slurry through the energy-dissipating orifice plate 2. The outer side of the adjusting rod 4 is slidably connected to the inner side of the groove of the energy-dissipating orifice plate 2.

[0042] A locking post 5 is fixedly connected to the outer side of the adjusting rod 4, which cooperates with the locking hole 7 on the inner side of the mixing buffer pool 1 to realize the positioning and fixation of the adjusting rod 4. Multiple locking holes 7 are opened on the inner side of the mixing buffer pool 1. The outer side of the locking post 5 is slidably connected to the inner side of the locking hole 7. A locking return spring 6 is fixedly connected to the side of the adjusting rod 4 away from the adjusting rod 4. When it is necessary to adjust the position of the adjusting rod 4, the operator can overcome the elasticity of the locking return spring 6 and pull the locking post 5 out of the locking hole 7 for adjustment. After adjustment, the adjusting rod 4 is released, and the locking return spring 6 will automatically push the locking post 5 back into the locking hole 7 to realize the automatic reset and fixation of the adjusting rod 4. This makes the adjustment process more convenient and stable. The other end of the locking return spring 6 is fixedly connected to the inner side of the groove of the energy dissipation plate 2.

[0043] The feeding and mixing assembly includes a primary mixing motor 11, which is the power source of the feeding and mixing assembly. A stirring guide plate 12 is fixedly connected to the outer side of the output end of the primary mixing motor 11. The blades of the stirring guide plate 12 are inclined and generate a strong stirring force when rotating, which guides and promotes the uniform mixing of slurry and reagents, and can guide the flow direction of slurry. The outer side of the stirring guide plate 12 is rotatably connected to the inner side of the mixing buffer tank 1. A slurry inlet pipe 13 is fixedly connected to the top of the mixing buffer tank 1. The slurry inlet pipe 13 introduces ilmenite slurry into the mixing buffer tank 1, providing a slurry source for subsequent mixing, buffering and flow rate adjustment operations.

[0044] Working principle: The slurry entering the mixing buffer tank 1 immediately undergoes the first stage of treatment, flowing through the energy dissipation orifice plate 2, which is covered with energy dissipation and bubble-generating holes 3. When the high-speed slurry impacts the energy dissipation orifice plate 2, some of the slurry is forced to pass through the narrow energy dissipation and bubble-generating holes 3. During this process, the kinetic energy of the slurry is significantly reduced due to friction of the hole wall and the limitation of the hole diameter, and the flow velocity decreases rapidly. At the same time, due to the high-speed shearing action of the slurry, numerous microbubbles are generated inside and at the orifice opening. These bubbles flow with the slurry, further promoting the slurry itself and the interaction between the slurry and the additives. The mixing of the two materials allows for more thorough contact. Operators can manually pull the adjusting rod 4 according to the actual slurry conditions. The adjusting rod 4 slides in the channel inside the energy dissipation plate 2. By changing the position or tilt angle of the energy dissipation plate 2 relative to the slurry flow, the actual flow rate of the slurry through the energy dissipation plate 2 can be flexibly adjusted. The positioning of the adjusting rod 4 relies on the tight fit between the locking column 5 and the locking hole 7. After each adjustment, the locking reset spring 6 will automatically push the locking column 5 into the corresponding locking hole 7 to ensure that the adjusting rod 4 is in a stable position and prevent it from shifting due to the impact of the slurry.

[0045] Next, the primary mixing motor 11 starts to run. The motor output shaft drives the stirring guide plate 12 to rotate at high speed in the mixing buffer tank 1. The blades of the stirring guide plate 12 have an inclined angle. When the blades rotate, they will generate a strong stirring force on the surrounding slurry, causing the slurry to form a complex circulation in the mixing buffer tank 1. This circulation can further mix the already initially mixed slurry and additives evenly. On the other hand, the guiding effect of the guide plate can accurately guide the flow direction of the slurry, promote the continuous circulation of the slurry, and ensure that every part of the slurry can fully contact the additives to achieve a more perfect initial mixing.

[0046] The slurry, after initial configuration and mixing, enters the flow regulating mechanism through the slurry guide pipe 14. Here, the opening and closing control motor 16, as the power core, begins to work. After the motor starts, the drive gear 17 at its output end rotates at high speed. The drive gear 17 meshes with the gear disk 18. Due to the transmission characteristics of the gears, the rotational torque of the drive gear 17 is transmitted to the gear disk 18, causing the gear disk 18 to rotate inside the regulating shell 15. The multiple arc-shaped grooves 19 on the outer side of the gear disk 18 play a key role at this time. One end of the opening and closing connecting rod 21 is embedded in the arc-shaped groove 19. Within 9, as the gear disk 18 rotates, the opening and closing connecting rod 21 rotates along the trajectory of the arc groove 19. The other end of the opening and closing connecting rod 21 is connected to the opening and closing valve plate 23, which then transmits the rotational motion to the opening and closing valve plate 23, causing the opening and closing valve plate 23 to rotate around the rotating column 24. By precisely controlling the speed, direction, and running time of the opening and closing control motor 16, the opening and closing angle of the opening and closing valve plate 23 can be precisely adjusted, changing the size of the pipe opening. This achieves precise control of the flow rate of the ilmenite slurry, meeting the stringent requirements of the subsequent flotation process for the slurry flow rate.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
