Description

TECHNICAL FIELD

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

[0002] Flotation is based on physical and chemical principles, and realizes the selective separation of useful minerals and gangue according to the difference in hydrophobicity of the mineral surface. It is the best method for removing impurities from fine-grained minerals and coal. In the flotation process, hydrophobic mineral particles are preferentially captured by bubbles to complete mineralization and floatation to form concentrate, while hydrophilic mineral particles remain in the flotation tank as tailings. The flotation efficiency depends on the probability of the occurrence of the three key sub-processes of collision, adhesion and detachment in the particle-bubble mineralization behavior. Since the initial stage of flotation, the particle-bubble mineralization behavior has been a research hotspot in the field.

[0003] Although flotation technology has achieved remarkable success in practice, there are still many problems 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 field production. The traditional method for studying the floatability of mineral particles usually uses a single-tank flotation machine for unit flotation test, and the floatability of the mineral is determined by analyzing the concentrate and tailings. However, this method cannot visualize the particle-bubble interaction behavior in the tank, and there are many influencing factors during the test. Researchers often cannot monitor and analyze various dynamic changes in the flotation process in real time, and it is difficult to judge the main influencing factors, which leads to a theoretical understanding of the interaction between bubbles and particles, and cannot 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 of particles and bubbles has made significant progress. However, existing tests mostly rely on quasi-static conditions, and the test process is one-sided, generally single-factor tests such as contact angle test, induction time test, etc., which cannot truly reflect the instantaneous mechanical action on particles in the flotation process. This deficiency not only limits the in-depth study of the interaction mechanism between particles and bubbles, but also makes it difficult for research results to provide targeted guidance for actual production. Therefore, a new detection method and device are urgently needed to effectively simulate and study the dynamic behavior of particles and bubbles under laboratory conditions. This method should have the ability to monitor the mineralization behavior of particles and bubbles in real time under dynamic conditions, help researchers understand the interaction mechanism between particles and bubbles, and provide scientific basis for optimizing the flotation process.

[0033] The preferred embodiments of the present application will be described in detail below with reference to the drawings, which form a part of this specification, and together with the embodiments of the present application to explain the principles of the present application, and are not intended to limit the scope of the present application.

[0034] One specific embodiment of the present application, as shown in Figure 1 The present application discloses a device for detecting the mineralization behavior of particles and bubbles, which comprises 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 is used to shoot images of particles and bubbles in the test environment.

[0035] In combination with Figure 1 and Figure 2 The test system 1 comprises a top cover driving shelter 11, a connecting channel 12 and a fluidized tank 13. The lower end of the top cover driving shelter 11 is connected to the top of the fluidized 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 shelter 11 and the top of the fluidized tank 13. In other words, the upper end of the connecting channel 12 is connected to the lower end of the top cover driving shelter 11, and the lower end of the connecting channel 12 is connected to the upper end of the fluidized tank 13. In this embodiment, by connecting a narrow channel (i.e. the connecting channel 12) between the fluidized tank 13 and the top cover driving shelter 11, the influence of the turbulent flow in the top cover driving shelter 11 on the collision and adhesion detection of particles and bubbles is effectively avoided.

[0036] As shown in Figure 2 and Figure 3 The top cover driving shelter 11 is provided with a first water inlet 111, a second water inlet 112 and a third water inlet 113. The first water inlet 111, the second water inlet 112 and the third water inlet 113 are all arranged at the bottom of the top cover driving shelter 11. The second water inlet 112 and the third water inlet 113 are arranged on the two sides of the first water inlet 111. Preferably, the second water inlet 112 and the third water inlet 113 are symmetrically arranged on the two 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 upward water flow inlet pipe 14.

[0037] It is worth noting that the top cover driving shelter 11 is an integral independent structure. The first water inlet 111 of the top cover driving shelter 11 and the upper end of the connecting channel 12 are both provided with a quick connector. The first water inlet 111 of the top cover driving shelter 11 is connected to the upper end of the connecting channel 12 through the quick connector, which facilitates the replacement of top cover driving shelters 11 of different sizes according to the test requirements. The length-width ratio of the top cover driving shelter 11 is 0.5, and the length-height ratio is 0.5-2.0.

[0038] As shown in Figure 2 and Figure 4As shown in

[0039] To fill the fluidized tank 13 with particles, as shown in Figure 2 and Figure 4 The fluidized tank 13 is provided with a filling port 133 at the top of the second tank body 132 below the first tank body 131. To facilitate the discharge of the material in the fluidized tank 13, the lower end of the fluidized tank 13 is provided with a first discharge port 134. It should be noted that since the fluidized tank 13 is filled with liquid, a sealing cover is required for the filling port 133 to prevent liquid leakage.

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

[0041] To transport water in the first water tank 15 to the fluidized tank 13, as shown in Figure 1 and Figure 2 The test system 1 further comprises a first centrifugal pump 18 connected to the fluidized bed layer water inlet pipe 16. As an example, the fluidized bed layer water inlet pipe 16 is provided with two pipes. One of the two pipes has its two ends connected to the first water tank 15 and the water inlet of the first centrifugal pump 18, respectively. The other pipe has its two ends connected to the water outlet of the first centrifugal pump 18 and the water distribution plate 17, respectively. To monitor and adjust the flow rate in the fluidized bed layer water inlet pipe 16, as shown in Figure 1 and Figure 2 The test system 1 further comprises a first liquid flow meter 19 arranged on the fluidized bed layer water inlet pipe 16.

[0042] To form bubbles in the fluidized tank 13, as shown in Figure 1 and Figure 2As shown, the test system 1 further comprises a microinjector 10, which is communicated with the inside of the fluidization tank 13 through a capillary. Specifically, one end of the capillary penetrates through the side wall of the fluidization tank 13, and the other end is connected with the microinjector 10. It should be noted that, since the inside of the fluidization tank 13 is filled with liquid, in order to avoid the liquid flowing out from the capillary, the capillary needs to be sealed with the side wall of the fluidization tank 13.

[0043] As shown in Figure 1 , the test system 1 of the embodiment is divided into a collision and adhesion detection area I and a detachment 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 upward water flow. The bubbles are injected through the side and mineralized with the particles to form particle-bubble gas floc. The gas floc floats along the connecting channel 12 to the detachment stability test area II. The main body of the detachment stability test area II is a top cover driven shelter 11. By accurately controlling the driving speed of the water flow of the water circulation system 2, different flow field structures and strengths can be simulated to simulate the actual flotation environment and further study the influence of the flow field on the interaction between the particles and the bubbles. In order to facilitate the observation of the interaction between the particles and the bubbles, the entire test system 1 is constructed of transparent materials (such as acrylic plates) to facilitate visual observation and data recording. The high-speed dynamic camera 32 can realize more accurate recording and research on the entire process of particle-bubble mineralization.

[0044] The detachment stability test area II comprises the top cover driven shelter 11. By applying a flowing fluid on the top of the top cover driven shelter 11, due to the influence of the boundary condition, the fluid layer close to the top cover will first move, and then the movement will be transmitted to the fluid layer below through the viscous effect. With the development of the flow, one or more vortices with different rotation directions will be formed in the chamber. The second water inlet 112 and the third water inlet 113 are respectively arranged on the two sides of the first water inlet 111. By injecting the upward water flow, a microgravity field can be constructed in the top cover driven shelter 11.

[0045] As shown in Figure 1 and Figure 5 , the water circulation system 2 comprises a second water tank 21, a turbulent main path 22, a first turbulent branch path 23 and a second turbulent branch path 24. One end of the turbulent main path 22 is communicated with the second water tank 21, and the other end is communicated with one end of the first turbulent branch path 23 and one end of the second turbulent branch path 24. The other end of the first turbulent branch path 23 is communicated with the top cover driven shelter 11, and the other end of the second turbulent branch path 24 is communicated with the top cover driven shelter 11.

[0046] In order to realize the water inlet from the upper end of the top cover driven shelter 11, as shown in Figure 2 and Figure 3As shown, the top cover driving shelter 11 is further provided with a fourth water inlet 114 and a fifth water inlet 115, both of which are arranged at the upper end of the top cover driving shelter 11 and symmetrically arranged at both sides of the top cover driving shelter 11.

[0047] In combination Figure 1 and Figure 5 As shown, the water circulation system 2 further comprises a first turbulent main pipeline 25 and a second turbulent main pipeline 26, one end of the first turbulent main pipeline 25 is connected with the fourth water inlet 114 and the other end is communicated with the first turbulent branch pipeline 23, one end of the second turbulent main pipeline 26 is communicated with the fifth water inlet 115 and the other end is communicated with the second turbulent branch pipeline 24. It should be noted that the first turbulent main pipeline 25 and the second turbulent main pipeline 26 are connected with the top cover driving shelter 11 through quick connectors, which can realize quick connection and replacement of the top cover driving shelter 11.

[0048] In order to realize the control of the water inlet mode of the top cover driving shelter 11, i.e. the switching of single vortex flow field and double vortex flow field, in combination Figure 1 and Figure 5 As shown, the water circulation system 2 further comprises a first electromagnetic valve 27 and a second electromagnetic valve 28, the first electromagnetic valve 27 is arranged at the first turbulent main pipeline 25 and the fourth water inlet 114, and the second electromagnetic valve 28 is arranged at the second turbulent main pipeline 26 and the fifth water inlet 115. Exemplarily, the first electromagnetic valve 27 is arranged on the first turbulent main pipeline 25, and the second electromagnetic valve 28 is arranged on the second turbulent main pipeline 26.

[0049] The first centrifugal pump 18 is started, and the water in the first water tank 15 enters the fluidization tank 13 through the first centrifugal pump 18 and is uniformly distributed through the water distribution plate 17 connected with the fluidized bed water inlet pipe 16, so as to ensure that the mineral particles can be fully fluidized. A single bubble is generated in the middle of the fluidization tank 13 through the microsyringe 10, the bubble collides with the fluidized particles to realize mineralization, and the mineralized bubble enters the top cover driving shelter 11 through the connecting channel 12 and then moves under the action of a preset vortex. The second centrifugal pump 202 is started, and a limited vortex is generated in the top cover driving shelter 11 under the driving action of the fluid in the first turbulent main pipeline 25 and the second turbulent main pipeline 26. The water flow speed is adjusted through the control of the first electromagnetic valve 27, the second electromagnetic valve 28 and the upward water flow inlet pipe 14, so as to control the vortex of different structures. Different vortex structures have a significant influence on the particle-bubble detachment behavior: strong vortexes accelerate detachment by providing high shear force, while weak vortexes may lead to reduced detachment efficiency; large vortexes have a wide range of action and are suitable for continuous disturbance; small vortexes have high energy density and are more conducive to efficient detachment; symmetric vortexes provide a uniform force field and are suitable for stable detachment research, while asymmetric vortexes increase randomness and can simulate complex working conditions. In addition, the frequency and center position of the vortex also affect its action range and detachment effect. Through reasonable regulation of the vortex structure, the particle-bubble separation probability can be reduced, and a theoretical basis is provided for the accurate control of the flotation process. In the embodiment, the fourth water inlet 114 and the fifth water inlet 115 are arranged on the top of the top cover driving shelter 11, the fourth water inlet 114 and the fifth water inlet 115 are connected with the first turbulent main pipeline 25 and the second turbulent main pipeline 26 respectively, the first electromagnetic valve 27 and the second electromagnetic valve 28 are arranged on the first turbulent main pipeline 25 and the second turbulent main pipeline 26 respectively, when the first electromagnetic valve 27 and the second electromagnetic valve 28 are both opened, a double-vortex flow field can be formed in the top cover driving shelter 11, when the first electromagnetic valve 27 or the second electromagnetic valve 28 is closed, a single-vortex flow field can be formed in the top cover driving shelter 11, and a variety of flow field structures can be simulated flexibly according to the test requirements, so as to provide a more accurate basis for the flow field design of the flotation equipment.

[0050] In order to monitor the flow of liquid on the turbulent main line 22, the first turbulent branch line 23 and the second turbulent branch line 24, the second liquid flow meter 29, the third liquid flow meter 20 and the fourth liquid flow meter 201 are arranged on the turbulent main line 22, the first turbulent branch line 23 and the second turbulent branch line 24 respectively. Figure 1 Figure 5 In order to monitor the flow of liquid on the turbulent main line 22, the first turbulent branch line 23 and the second turbulent branch line 24, the second liquid flow meter 29, the third liquid flow meter 20 and the fourth liquid flow meter 201 are arranged on the turbulent main line 22, the first turbulent branch line 23 and the second turbulent branch line 24 respectively.

[0051] Considering the transportation of water in the second water tank 21, the second water tank 21 is connected with the first water tank 15 through the first water inlet pipe 19 and the second water inlet pipe 211. Figure 1 Figure 5 ​​As shown, the water circulation system 2 also includes a second centrifugal pump 202, which is located on the turbulent main path 22. Understandably, the water circulation system 2 also includes a liquid distributor 203, which connects the turbulent main path 22, the first turbulent branch path 23, and the second turbulent branch path 24, distributing 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 achieve water recycling, combined with Figure 1 and Figure 5 As shown, the water circulation system 2 also includes a particle recovery column 204, an outlet pipe 205, and a return pipe 206. One end of the outlet pipe 205 is connected to the top cover drive cabin 11, and the other end is connected to the middle of the particle recovery column 204. One end of the 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-covered drive 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 outlet. Figure 1 , Figure 2 and Figure 3 As shown, one end of the water 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 water 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] Because air bubbles and particles are simultaneously flowing back from the top cover drive compartment 11, in order to puncture the air bubbles and allow the particles to be discharged from the second discharge port, such as... Figure 1 As shown, the particle recovery column 204 is equipped with a screen 207. The bottom of the screen 207 is provided with a cone. The screen 207 is located above the sixth water inlet. The cone of the screen 207 punctures the air bubbles, causing the particles to fall off and sink, and are discharged through the second discharge port.

[0054] It should be noted that a third solenoid valve is installed at the second discharge port. The third solenoid valve is used to control the opening and closing of the second discharge port. When the particles accumulate to a certain amount (or after the test), the second discharge port is opened by the third solenoid valve. A fourth solenoid valve and a fifth solenoid valve are respectively installed on the water outlet pipe 205 and the water return pipe 206 to prevent the liquid in the top cover driving container 11 and the second water tank 21 from flowing 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, and 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 with the computer 33. The shooting system 3 can capture and analyze the motion behavior of particles-bubbles in real time, so as to realize high-quality visualization.

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

[0057] The present application has significant innovation and comprehensiveness, and can efficiently integrate various functional modules. Compared with traditional detection equipment, the present application realizes comprehensive detection and analysis of the mineralization behavior of particles-bubbles. 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, improves the convenience of observation and data recording. This multifunctional integrated design not only improves the test efficiency and data accuracy, but also provides a more friendly operation interface for users, simplifies the complex test process. In addition, the modular design of the device has good flexibility and expandability, different flow field structures can be constructed according to the fluid velocity, and the function can be adjusted or upgraded according to different test requirements, which is suitable for the research and application requirements of various minerals. This innovative overall equipment will greatly promote the development of mineral flotation technology, and will provide more scientific and efficient solutions for related industries, and promote the technological progress and application popularization of mineral engineering.

[0058] The present application allows researchers to flexibly simulate various flow field structures according to test requirements, and provides 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 communication form (such as single-side water inlet and double-side water inlet), the structure and strength of the flow field can be accurately adjusted, and the influence of the upward water flow on the detachment of particles-bubbles can be studied by adjusting the size of the water flow at the bottom of the top cover driving cabin 11. This flexible design enables researchers to deeply analyze the interaction between particles and bubbles under different flow field conditions, not only provides a new idea for the optimization of existing equipment, but also lays a theoretical foundation for the research and development of new equipment, thereby improving the separation efficiency and mineral recovery rate. This progress not only has important significance for technical development, but also promotes the improvement of the entire industry in terms of technological innovation and resource utilization.

[0059] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
