Description

Technical Field

[0001] The invention relates to the technical field of mineral flotation, and in particular to a device for detecting mineralization behavior of flotation particles and bubbles. Background Art

[0002] Flotation is based on physical chemistry. It selectively separates useful minerals from gangue according to the difference in hydrophobicity of mineral surfaces. It is the best means to remove impurities from fine-grained minerals and coal. During the flotation process, hydrophobic mineral particles are preferentially captured by bubbles to complete mineralization and float to form concentrates, while hydrophilic mineral particles remain in the flotation tank and become tailings. Among them, the flotation efficiency depends on the probability of occurrence of the three key sub-processes of collision, adhesion, and desorption in the particle-bubble mineralization behavior. Since the early days of flotation, particle-bubble mineralization behavior has been a research hotspot in the field.

[0003] Although flotation technology has made remarkable achievements in practice, there are still many problems that need to be solved in the laboratory research stage. The study of the floatability of mineral particles in the laboratory is of great significance for guiding on-site production. The traditional method of studying the floatability of mineral particles usually uses a single-tank flotation machine to conduct unit flotation tests, and the floatability of minerals is judged by analyzing the concentrate and tailings. However, this method is difficult to visualize the behavior of particle-bubble interaction in the tank. There are many influencing factors during the experiment. Researchers are often unable to monitor and analyze various dynamic changes in the flotation process in real time, and it is difficult to judge the main influencing factors, resulting in the understanding of the interaction between bubbles and particles remaining at the theoretical level and unable to form effective guidance.

[0004] With the rapid development of mechanical instruments and high-speed dynamic technology, the research on the interaction force and behavior mechanism between particles and bubbles has made significant progress. However, existing experiments mostly rely on quasi-static conditions, and the test process is too one-sided. They are generally single-factor tests, such as contact angle tests, induction time tests, etc., which cannot truly reflect the instantaneous mechanical effects on particles during flotation. This deficiency not only limits the in-depth study of the particle-bubble interaction mechanism, but also makes it difficult for research results to provide targeted guidance for actual production. Therefore, there is an urgent need for a new detection method and device that can effectively simulate and study the dynamic behavior of particles and bubbles under laboratory conditions. This method should be able to monitor the mineralization behavior of particles and bubbles under dynamic conditions in real time, helping researchers to deeply understand the interaction mechanism between particles and bubbles, thereby providing a scientific basis for optimizing flotation processes. Summary of the invention

[0005] In view of the above analysis, an embodiment of the present invention aims to provide a flotation particle and bubble mineralization behavior detection device to solve the problem that the existing test equipment is inconsistent with the actual flotation environment due to fewer test factors.

[0006] The present invention provides a flotation particle and bubble mineralization behavior detection device, including a test system, a water circulation system and a shooting system;

[0007] The test system comprises a top cover driving cabin, a connecting channel and a fluidizing tank, wherein the lower end of the top cover driving cabin is connected to the top of the fluidizing tank through the connecting channel;

[0008] The water circulation system is in communication with the top cover driving cabin, and the photographing system is used to photograph the mineralization behavior of particles and bubbles in the top cover driving cabin.

[0009] Furthermore, the test system also includes a first water tank and a fluidized bed water inlet pipe, one end of the fluidized bed water inlet pipe is connected to the first water tank, and the other end is arranged in the fluidized tank.

[0010] Furthermore, the test system also includes a first centrifugal pump, which is connected to the water inlet pipe of the fluidized bed.

[0011] Furthermore, the test system also includes a first liquid flow meter, which is arranged on the water inlet pipe of the fluidized bed.

[0012] Furthermore, the test system also includes a micro-injector, and the micro-injector is connected to the interior of the fluidization tank through a capillary.

[0013] Furthermore, the fluidizing tank includes a first tank body and a second tank body, the first tank body is arranged above the second tank body, the lower end of the connecting channel is connected to the top of the first tank body, and the micro-injector and the fluidized bed water inlet pipe are both connected to the second tank body.

[0014] Furthermore, a filling port is provided at the upper end of the second tank body, and a first discharge port is provided at the lower end of the second tank body.

[0015] Furthermore, the water circulation system includes a second water tank, and the second water tank is connected to the top cover driving cabin.

[0016] Furthermore, the shooting system includes a light source and a high-speed dynamic camera, and the light source and the high-speed dynamic camera are respectively arranged on both sides of the top cover driving cabin.

[0017] Furthermore, the shooting system also includes a computer, and the computer is connected to the high-speed dynamic camera.

[0018] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0019] (1) The present invention effectively avoids the influence of turbulence in the top cover driving cabin on the collision and adhesion detection of particles and bubbles by connecting a narrow channel between the fluidizing trough and the top cover driving cabin; a water inlet connected to the connecting channel and a water inlet connected to the rising water inlet pipe are provided at the bottom of the top cover driving cabin, and water inlets connected to the turbulent main pipeline are provided on both sides of the top of the top cover driving cabin. By applying a flowing fluid on the top of the top cover driving cabin, due to the influence of boundary conditions, the fluid layer close to the top cover will move first, and then transmit this movement to the fluid layer below through the viscosity effect. As the flow develops, one or more vortices with different rotation directions will be formed inside the chamber, which can simulate different flow field structures and intensities, and further study the influence of the flow field on the interaction between particles and bubbles, which not only provides new ideas for the optimization of existing equipment, but also lays a theoretical foundation for the research and development of new equipment, thereby improving separation efficiency and mineral recovery rate.

[0020] (2) The water circulation system of the present invention includes a second water tank, and a turbulent branch and a turbulent main pipe for communicating with the top cover driving cabin. The top two ends of the top cover driving cabin are respectively connected to a turbulent main pipe and a turbulent branch. By changing the water flow driving speed in the turbulent main pipe and the opening and closing of the two turbulent branches, the structure and intensity of the flow field can be accurately adjusted to simulate different test conditions, and provide a flotation environment close to the actual one for studying the influence of the flow field on the interaction between particles and bubbles, so as to obtain accurate data for guiding time production. At the same time, the top of the top cover driving cabin is connected to the particle collection column and the second water tank through the return pipe, realizing water circulation and particle recovery.

[0021] (3) The present invention can more accurately evaluate the floatability of mineral particles through real-time dynamic monitoring and data analysis. Compared with traditional particle floatability detection methods, such as contact angle test and induction time test, these methods are usually limited by single test conditions and inconsistent with the actual flotation process, resulting in limited evaluation results. The present invention provides more comprehensive and reliable data by comprehensively considering the three key processes of collision, adhesion and desorption, and realizes a more accurate analysis of the floatability of raw coal, thereby providing a more guiding basis for actual production.

[0033] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0034] A specific embodiment of the present invention, as Figure 1 As shown, a flotation particle and bubble mineralization behavior detection device is disclosed, including a test system 1, a water circulation system 2 and a shooting system 3. The water circulation system 2 creates a test environment for the test system 1, and the water circulation system 2 is used to shoot particle and bubble images in the test environment.

[0035] Combination Figure 1 and Figure 2 As shown, the test system 1 includes a top cover driving cabin 11, a connecting channel 12 and a fluidizing tank 13. The lower end of the top cover driving cabin 11 is connected to the top of the fluidizing tank 13 through the connecting channel 12. The cross section of the connecting channel 12 is smaller than the bottom of the top cover driving cabin 11 and the top of the fluidizing tank 13. The top of the fluidizing tank 13 is connected to the top cover driving cabin 11 through a narrow channel (i.e., the connecting channel 12). In other words, the upper end of the connecting channel 12 is connected to the lower end of the top cover driving cabin 11, and the lower end of the connecting channel 12 is connected to the upper end of the fluidizing tank 13. In this embodiment, by connecting a narrow channel (i.e., the connecting channel 12) between the fluidizing tank 13 and the top cover driving cabin 11, the influence of the turbulence in the top cover driving cabin 11 on the collision and adhesion detection of particles and bubbles is effectively avoided.

[0036] like Figure 2 and Figure 3 As shown, the top cover driving cabin 11 is provided with a first water inlet 111, a second water inlet 112 and a third water inlet 113, which are all arranged at the bottom of the top cover driving cabin 11, and the second water inlet 112 and the third water inlet 113 are arranged on both sides of the first water inlet 111. Preferably, the second water inlet 112 and the third water inlet 113 are symmetrically arranged on both sides of the first water inlet 111. The upper end of the connecting channel 12 is connected to the first water inlet 111. The second water inlet 112 and the third water inlet 113 are respectively connected to an ascending water flow inlet pipe 14.

[0037] It is worth noting that the top cover driving cabin 11 is an integral independent structure, and the first water inlet 111 of the top cover driving cabin 11 and the upper end of the connecting channel 12 are both provided with a live interface (i.e., a quick interface), and the first water inlet 111 of the top cover driving cabin 11 and the upper end of the connecting channel 12 are connected through a quick interface, which is convenient for replacing top cover driving cabins 11 of different sizes according to test requirements. The aspect ratio of the top cover driving cabin 11 is 0.5, and the length-to-height ratio is 0.5-2.0.

[0038] like Figure 2 and Figure 4As shown, the fluidizing tank 13 includes a first tank body 131 and a second tank body 132. The first tank body 131 is arranged above the second tank body 132. The first tank body 131 is a conical table structure, and the second tank body 132 is a columnar structure with equal cross-sections at the top and bottom. Preferably, the first tank body 131 is a truncated table, and the second tank body 132 is a cylindrical shape. The top diameter of the first tank body 131 is equal to the diameter of the connecting channel 12, and the bottom of the first tank body 131 is directly equal to the bottom of the second tank body 132. It should be noted that the fluidizing tank 13 is preferably integrally formed.

[0039] In order to fill the fluidizing tank 13 with particles, as Figure 2 and Figure 4 As shown, the fluidizing tank 13 is provided with a filling port 133, which is located at the top of the second tank body 132 and below the first tank body 131. In order to facilitate the discharge of the material in the fluidizing tank 13, the lower end of the fluidizing tank 13 is provided at the first discharge port 134. It should be noted that since the fluidizing tank 13 contains liquid, in order to prevent liquid from leaking from the filling port 133, a sealing cover is required for the filling port 133.

[0040] Combination Figure 1 and Figure 2 As shown, the test system 1 also includes a first water trough 15, a fluidized bed water inlet pipe 16 and a water distribution plate 17. The first water trough 15 is connected to the water distribution plate 17 through the fluidized bed water inlet pipe 16. The water distribution plate 17 is arranged in the fluidizing trough 13. One end of the fluidized bed water inlet pipe 16 is connected to the first water trough 15, and the other end is connected to the water distribution plate 17 through the bottom or side wall of the fluidizing trough 13.

[0041] In order to transport the water in the first water tank 15 to the fluidizing tank 13, the Figure 1 and Figure 2 As shown, the test system 1 also includes a first centrifugal pump 18, which is connected to the fluidized bed water inlet pipe 16. For example, there are two fluidized bed water inlet pipes 16, one of which has two ends connected to the first water tank 15 and the water inlet of the first centrifugal pump 18, and the other has two ends connected to the water outlet of the first centrifugal pump 18 and the water distribution plate 17. In order to monitor the flow in the fluidized bed water inlet pipe 16 so as to adjust it, the fluidized bed water inlet pipe 16 is combined with the first centrifugal pump 18 to adjust the flow rate. Figure 1 and Figure 2 As shown, the test system 1 further includes a first liquid flow meter 19 , which is disposed on the fluidized bed water inlet pipe 16 .

[0042] Considering the need to form bubbles in the fluidizing tank 13, combined with Figure 1 and Figure 2As shown, the test system 1 also includes a micro-injector 10, which is connected to the inside of the fluidizing tank 13 through a capillary. Specifically, one end of the capillary passes through the side wall of the fluidizing tank 13, and the other end is connected to the micro-injector 10. It should be noted that since the fluidizing tank 13 contains liquid, in order to prevent the liquid from flowing out of the capillary, a sealing treatment needs to be performed between the capillary and the side wall of the fluidizing tank 13.

[0043] like Figure 1 As shown, the test system 1 of this embodiment is divided into a collision and adhesion detection area I and a desorption stability test area II. The collision and adhesion detection area I adopts a fluidized bed structure. The particles are fluidized under the action of the rising water flow. The bubbles are injected from the side and mineralize with the particles to form particle-bubble gas flocs. The gas flocs float along the connecting channel 12 to the desorption stability test area II. The main body of the desorption stability test area II is the top cover driving cabin 11. By accurately controlling the water flow driving speed of the water circulation system 2, different flow field structures and intensities can be simulated to simulate a flotation environment close to the actual one, and further study the influence of the flow field on the interaction between particles and bubbles. In order to facilitate the observation of the interaction between particles and bubbles, the entire test system 1 is constructed of transparent materials (such as acrylic plates) to facilitate visual observation and data recording. The combination of a high-speed dynamic camera 32 can achieve more accurate recording and research of the entire process of particle-bubble mineralization.

[0044] The desorption stability test area II includes a top cover driving cabin 11. By applying a flowing fluid on the top of the top cover driving cabin 11, due to the influence of the boundary conditions, the fluid layer close to the top cover will move first, and then the movement will be transmitted to the fluid layer below through the viscosity effect. As the flow develops, one or more vortices with different rotation directions will be formed inside the chamber. The second water inlet 112 and the third water inlet 113 are respectively provided on both sides of the first water inlet 111. By injecting rising water flow, a microgravity field can be constructed in the top cover driving cabin 11.

[0045] Combination Figure 1 and Figure 5 As shown, the water circulation system 2 includes a second water trough 21, a turbulent main path 22, a first turbulent branch 23 and a second turbulent branch 24. One end of the turbulent main path 22 is connected to the second water trough 21, and the other end is connected to one end of the first turbulent branch 23 and one end of the second turbulent branch 24. The other end of the first turbulent branch 23 is connected to the top cover drive cabin 11, and the other end of the second turbulent branch 24 is connected to the top cover drive cabin 11.

[0046] In order to achieve water inlet from the upper end of the top cover driving cabin 11, Figure 2 and Figure 3As shown, the top cover driving cabin 11 is also provided with a fourth water inlet 114 and a fifth water inlet 115. The fourth water inlet 114 and the fifth water inlet 115 are both arranged at the upper end of the top cover driving cabin 11. The fourth water inlet 114 and the fifth water inlet 115 are symmetrically arranged on both sides of the top cover driving cabin 11.

[0047] Combination Figure 1 and Figure 5 As shown, the water circulation system 2 also includes a first turbulent main pipe 25 and a second turbulent main pipe 26, one end of the first turbulent main pipe 25 is connected to the fourth water inlet 114, and the other end is connected to the first turbulent branch 23, and one end of the second turbulent main pipe 26 is connected to the fifth water inlet 115, and the other end is connected to the second turbulent branch 24. It should be noted that the first turbulent main pipe 25 and the second turbulent main pipe 26 are both connected to the top cover drive cabin 11 by quick interface, which can realize the rapid connection and replacement of the top cover drive cabin 11.

[0048] In order to realize the control of the water inlet mode of the top cover driving cabin 11, that is, the switching of the single vortex flow field and the double vortex flow field, combined with Figure 1 and Figure 5 As shown, the water circulation system 2 further includes a first solenoid valve 27 and a second solenoid valve 28, wherein the first solenoid valve 27 is disposed at the first turbulent main conduit 25 and the fourth water inlet 114, and the second solenoid valve 28 is disposed at the second turbulent main conduit 26 and the fifth water inlet 115. Exemplarily, the first solenoid valve 27 is disposed on the first turbulent main conduit 25, and the second solenoid valve 28 is disposed on the second turbulent main conduit 26.

[0049] Start the first centrifugal pump 18, and the water in the first water tank 15 enters the fluidizing tank 13 through the first centrifugal pump 18, and is evenly distributed through the water distribution plate 17 connected to the fluidized bed water inlet pipe 16, ensuring that the mineral particles can be fully fluidized. A single bubble is generated in the middle of the fluidizing tank 13 by the micro-injector 10, and the bubble collides with the fluidized particles to achieve mineralization. The mineralized bubble enters the top cover drive cabin 11 through the connecting channel 12, and then moves under the action of the preset vortex. Turn on the second centrifugal pump 202, and under the driving action of the fluid in the first turbulent main pipeline 25 and the second turbulent main pipeline 26, a restricted vortex will be generated inside the top cover drive cabin 11. The water flow speed is adjusted by controlling the first solenoid valve 27, the second solenoid valve 28 and the rising water inlet pipe 14, thereby controlling the generation of vortices of different structures. Different vortex structures have a significant effect on the particle-bubble desorption behavior: strong vortices accelerate desorption by providing high shear force, while weak vortices may lead to reduced desorption efficiency; large vortices have a wide range of action and are suitable for continuous disturbances; small vortices have high energy density and are more conducive to efficient desorption; symmetric vortices provide a uniform force field and are suitable for stable desorption research, while asymmetric vortices increase randomness and can simulate complex working conditions. In addition, the frequency and center position of the vortex also affect its range of action and desorption effect. By rationally regulating the vortex structure, the probability of particle-bubble separation can be reduced, providing a theoretical basis for the precise control of the flotation process. In this embodiment, a fourth water inlet 114 and a fifth water inlet 115 are provided on both sides of the top of the top cover driving cabin 11, and the fourth water inlet 114 and the fifth water inlet 115 are respectively connected to the first turbulent main pipe 25 and the second turbulent main pipe 26, and the first turbulent main pipe 25 and the second turbulent main pipe 26 are respectively provided with a first solenoid valve 27 and a second solenoid valve 28. When the first solenoid valve 27 and the second solenoid valve 28 are both opened, a double vortex flow field can be formed in the top cover driving cabin 11. When the first solenoid valve 27 or the second solenoid valve 28 is closed, a single vortex flow field can be formed in the top cover driving cabin 11. It can flexibly simulate various flow field structures according to test requirements, and provide a more accurate basis for the flow field design of the flotation equipment.

[0050] In order to monitor the flow rate of the liquid on the turbulent main path 22, the first turbulent branch path 23 and the second turbulent branch path 24, the Figure 1 and Figure 5 As shown, the water circulation system 2 also includes a second liquid flow meter 29, a third liquid flow meter 20 and a fourth liquid flow meter 201. The second liquid flow meter 29 is arranged on the turbulent main path 22, the third liquid flow meter 20 is arranged on the first turbulent branch path 23, and the fourth liquid flow meter 201 is arranged on the second turbulent branch path 24.

[0051] Considering the transportation of water in the second water tank 21, combined with Figure 1 and Figure 5As shown, the water circulation system 2 further includes a second centrifugal pump 202, which is disposed on the turbulent main path 22. Understandably, the water circulation system 2 further includes a liquid diverter 203, which connects the turbulent main path 22, the first turbulent branch path 23, and the second turbulent branch path 24, and distributes water in the turbulent main path 22 to the first turbulent branch path 23 and the second turbulent branch path 24.

[0052] In order to realize water circulation, Figure 1 and Figure 5 As shown, the water circulation system 2 further includes a particle recovery column 204, a water outlet pipe 205 and a water return pipe 206. One end of the water outlet pipe 205 is connected to the top cover driving cabin 11, and the other end is connected to the middle of the particle recovery column 204. One end of the water return pipe 206 is connected to the second water tank 21, and the other end is connected to the particle recovery column 204. Specifically, as Figure 2 and Figure 3 As shown, the top of the top cover driving cabin 11 is provided with a first water outlet 116, the middle of the particle recovery column 204 is provided with a sixth water inlet, the top is provided with a second water outlet, and the bottom is provided with a second discharge port. Figure 1 , Figure 2 and Figure 3 As shown, one end of the outlet pipe 205 is connected to the first water outlet 116, and the other end is connected to the sixth water inlet of the particle recovery column 204; one end of the return pipe 206 is connected to the second water outlet of the particle recovery column 204, and the other end is connected to the second water tank 21.

[0053] Since bubbles and particles flow back from the top cover driving cabin 11 at the same time, in order to puncture the bubbles so that the particles are discharged from the second discharge port, Figure 1 As shown, the particle recovery column 204 is provided with a screen 207, and the bottom of the screen 207 is provided with cone thorns. The screen 207 is located above the sixth water inlet. The cone thorns of the screen 207 pierce the bubbles to make the particles fall off and sink, and are discharged through the second discharge port.

[0054] It should be noted that a third solenoid valve is provided at the second discharge port, and the third solenoid valve is used to control the opening and closing of the second discharge port. When the particles are enriched to a certain amount (or after the test is completed), the second discharge port is opened by the third solenoid valve. A fourth solenoid valve and a fifth solenoid valve are provided on the outlet pipe 205 and the return pipe 206, respectively, to prevent the top cover from driving the liquid in the square cabin 11 and the second water tank 21 to flow out of the second discharge port when the second discharge port is opened.

[0055] like Figure 1As shown, the shooting system 3 includes a light source 31, a high-speed dynamic camera 32 and a computer 33. The light source 31 and the high-speed dynamic camera 32 are respectively arranged on both sides of the top cover driving cabin 11. The high-speed dynamic camera 32 is connected to the computer 33. The shooting system 3 can capture and analyze the movement behavior of particles and bubbles in real time, thereby achieving high-quality visualization.

[0056] The structural design of this embodiment is intended to achieve the construction of a specific flow field so as to visualize the dynamic behavior of the three sub-processes (collision, adhesion, and desorption) of flotation particle-bubble mineralization. This structural design not only improves the flexibility and accuracy of the experiment, but also provides strong technical support for in-depth research on the interaction mechanism between particles and bubbles. The structure of this embodiment provides a scientific basis for optimizing the flotation process and improving the efficiency of mineral separation, and has important application prospects and industry value.

[0057] The present invention has significant innovation and comprehensiveness, and can efficiently integrate various functional modules. Compared with traditional detection equipment, it realizes comprehensive detection and analysis of particle-bubble mineralization behavior. The device not only combines the test system 1, the water circulation system 2 and the shooting system 3, but also realizes the visualization of the test process, and improves the convenience of observation and data recording. This multifunctional integrated design not only improves the test efficiency and data accuracy, but also provides users with a more user-friendly operation interface and simplifies complex test processes. In addition, the modular design of the device gives it good flexibility and scalability. Different flow field structures can be constructed according to the fluid velocity, and functions can be adjusted or upgraded according to different test requirements to adapt to the research and application needs of various minerals. This innovative overall equipment will not only greatly promote the development of mineral flotation technology, but also provide more scientific and efficient solutions for related industries, and promote technological progress and application promotion of mining engineering.

[0058] The present invention allows researchers to flexibly simulate a variety of flow field structures according to experimental requirements, providing a more accurate basis for the flow field design of flotation equipment. By changing the water flow driving speed at the top of the top cover driving cabin 11 and the connection form (such as single-sided water inlet and double-sided water inlet), the structure and strength of the flow field can be accurately adjusted. By adjusting the size of the water flow at the bottom of the top cover driving cabin 11, the effect of the rising water flow on the particle-bubble desorption can be studied. This flexible design enables researchers to deeply analyze the interaction between particles and bubbles under different flow field conditions, which not only provides new ideas for the optimization of existing equipment, but also lays a theoretical foundation for the research and development of new equipment, thereby improving separation efficiency and mineral recovery rate. This progress is not only of great significance to technological development, but will also promote the improvement of the entire industry in terms of technological innovation and resource utilization.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
