Description

Technical Field

[0001] The invention belongs to the technical field of hydrocyclone experimental equipment, and more specifically, particularly relates to a hydrocyclone cone section wear dynamic simulation experimental device. Background Art

[0002] As an important separation equipment, hydrocyclone has been widely used in many industrial fields such as mining, petroleum, chemical industry, environmental protection, etc. due to its efficient separation performance. In these application scenarios, hydrocyclone uses centrifugal force to separate particles of different density or particle size, and the cone section plays a key role in the whole separation process. However, due to its complex internal flow field, high-speed fluid carrying solid particles has a strong scouring effect on the inner wall of the cone section, which makes the cone section very easy to wear. The wear of the cone section will not only affect the separation efficiency of the hydrocyclone, resulting in a decline in product quality, but also significantly shorten the service life of the equipment, increase the maintenance cost and downtime of the equipment, and thus have a negative impact on the continuity and economy of the whole production process. Therefore, a dynamic simulation experimental device for the wear of the cone section of the hydrocyclone is needed.

[0003] The existing hydrocyclone cone wear simulation experimental device still has some shortcomings: 1. On the one hand, in terms of wear monitoring, traditional monitoring methods and devices can often only monitor the local position of the cone section, and cannot obtain the wear information of each part of the cone section in a comprehensive and real-time manner, and cannot effectively meet the experimental needs; 2. On the other hand, the particle concentration of the fluid entering the cyclone cannot be effectively adjusted, and the fluid is mixed unevenly, which cannot ensure the stability and consistency of the experimental fluid composition, resulting in poor repeatability and reliability of the experimental results; 3. In addition, the existing experimental device is not convenient enough in terms of installation and fixation of the cyclone body, and the positioning is inaccurate. It is easy to shake or displace during the experiment, which affects the accuracy of the experimental results. Moreover, the equipment is inconvenient to disassemble and replace, and it is not convenient to conduct comparative experiments on cyclone bodies of different materials, which reduces the experimental efficiency. Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a dynamic simulation experimental device for wear of the cone section of a hydrocyclone is provided, in order to achieve a more practical purpose.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The dynamic simulation experimental device for the wear of the conical section of the hydrocyclone is equipped with multiple shells equidistantly arranged on the inner circumference of the fixed ring. Ultrasonic sensors are installed equidistantly in each shell and closely attached to the surface of the conical section of the hydrocyclone body. It can monitor the change of the wall thickness of the conical section in real time from multiple positions and angles, comprehensively obtain wear information, accurately reflect the wear conditions of various parts of the conical section, provide experimental data for studying wear laws, improve the comprehensiveness and accuracy of wear detection. By adopting the method of dynamic wall thickness measurement and sensors based on the ultrasonic reflection principle, it can accurately calculate the wall thickness of the conical section according to the time difference between the transmitted and received signals, achieve high-precision detection of the wear degree of the conical section, and capture even the slightest change in wall thickness, which helps to deeply analyze the wear process.

[0015] 2. The dynamic simulation experimental device for the wear of the conical section of the hydrocyclone controls the movement of the U-shaped long plate through a motor-driven threaded rod, changes the relative position between the through port and the feeding pipe, and can add particles into the liquid storage tank, thereby being able to adjust the concentration of the liquid flowing into the hydrocyclone body to meet the requirements of different experiments for particle concentration.

[0016] 3. The hydrocyclone body is initially positioned by the cooperation of the groove on the connecting plate and the convex block on the bracket, and then the connecting plate is limited and locked by the abutting block, and structures such as the slip ring and the push block are used to make the ultrasonic sensor closely attached to the conical section.

An opening 64 is formed on one side of the bottom surface of the U-shaped long plate 63. A feeding port 69 is formed on one side of the upper surface of the liquid storage tank 6.

A threaded rod 3 66 is fixedly connected to the output shaft 2 of the motor 2 65. The threaded rod 3 66 movably penetrates the ear block 74 and is threadedly connected to the ear block 74. A driving gear 67 and a driven gear 72 are fixedly installed on one end of the threaded rod 3 66 and the stirring shaft 7, respectively. The driving gear 67 and the driven gear 72 are meshed with each other. The meshing of the driving gear 67 and the driven gear 72 drives the stirring shaft 7 to rotate, and the stirring blades 71 on the stirring shaft 7 rotate accordingly, so as to stir and mix the liquid in the liquid storage tank 6 and the newly added particles, so that the liquid in the liquid storage tank 6 is mixed more evenly.

Each protrusion 22 movably penetrates the groove 34, and is used to position the installation of the cyclone body 3, so as to facilitate the rapid installation of the cyclone body 3. The fixed ring 4 is fixedly connected to the two brackets 2. A through-block 43 is fixedly installed at the outer end of each housing 41. Each through-block 43 movably penetrates through the fixed ring 4. A connecting block 44 is fixedly installed on each through-block 43. A round rod 45 is fixedly installed inside each connecting block 44. Each round rod 45 movably penetrates through the fixed ring 4. A spring 46 is movably sleeved on each round rod 45. Each connecting block 44 is fixedly connected to the outer side of the fixed ring 4 through the spring 46 respectively. A limiting block 47 is fixedly installed on each round rod 45. Each limiting block 47 is located inside the fixed ring 4. Four push blocks 51 are fixedly installed at equal intervals on the inner circumference of the sliding ring 5. The surface of each push block 51 is respectively in contact with the surface of each connecting block 44, and the contacting surfaces are all designed as inclined surfaces. Due to the inclined surface design of the contacting surface between the push block 51 and the connecting block 44, when the push block 51 moves downward, it will exert a force on the connecting block 44, causing the four connecting blocks 44 to move closer to the center of the fixed ring 4, thereby driving the four housings 41 to approach, so that the ultrasonic sensors 42 on each housing 41 are closely attached to the surface of the conical section of the cyclone body 3, so as to monitor the wall thickness change of the conical section in real time; Sliding blocks 52 are fixedly installed on both sides of the sliding ring 5. A first chute 23 is formed on the surface of each bracket 2. Each sliding block 52 is respectively slidably installed in the first chute 23. A first threaded rod 24 is rotatably installed in each first chute 23. Each first threaded rod 24 respectively penetrates through the sliding block 52 and is threadedly connected to the sliding block 52. A first motor is arranged in each bracket 2 respectively, which is used to drive the first threaded rod 24 to rotate. By rotating the first threaded rod 24, the sliding ring 5 can be driven to move in the vertical direction, so as to adjust the distance between the ultrasonic sensor 42 and the conical section of the cyclone body 3; A first bevel gear 25 is fixedly installed at the top of each first threaded rod 24. A second threaded rod 26 is rotatably installed at the top of each bracket 2. A second bevel gear 27 is fixedly installed on each second threaded rod 26. Each first bevel gear 25 is respectively meshed with each second bevel gear 27. A second chute 28 is formed on the upper surface of each bracket 2.

Each second threaded rod 26 respectively penetrates through the resisting block 29 and is threadedly connected to the resisting block 29. The bottom end of each resisting block 29 is respectively slidably installed in the second chute 28. Each resisting block 29 slides to the upper end of the connecting plate 31 to limit and lock the connecting plate 31. The second threaded rod 26 drives the resisting block 29 to move closer to the cyclone body 3 along the second chute 28. Finally, the two resisting blocks 29 are attached to the upper end of the connecting plate 31 to complete the fixation of the cyclone body 3 and ensure the stability of the equipment during the experiment.

[0036] The working principle of this embodiment: Step 1: Initial installation and positioning: Insert the cyclone body 3 into the bearing ring 21, align the groove 34 on the connecting plate 31 with the bump 22 on the bracket 2 to achieve the preliminary positioning of the connecting plate 31 at the upper end of the bearing ring 21. At the same time, ensure that the overflow pipe 35 and the underflow pipe 36 are communicated with the inner cavity of the circulation tank 9, and fixedly connect the feed pipe 32 and the first connecting pipe 81 through the flange 33 and bolts. Step 2: Sensor fitting and equipment fixation: Start the first motor in the bracket 2. The first motor drives the first threaded rod 24 to rotate. The rotation of the first threaded rod 24 causes the slider 52 to move downward along the first chute 23, thereby driving the slip ring 5 to move downward. The four push blocks 51 on the slip ring 5 move downward accordingly. Since the mating surface between the push block 51 and the connecting block 44 is designed as an inclined plane, when the push block 51 moves downward, it will exert a force on the connecting block 44, causing the four connecting blocks 44 to move closer to the center of the fixed ring 4, thereby driving the four housings 41 to approach each other, so that the ultrasonic sensors 42 on each housing 41 are closely attached to the surface of the conical section of the cyclone body 3 to monitor the wall thickness change of the conical section in real time. The equidistant and closely attached installation method can detect the conical section from multiple positions and angles to ensure comprehensive acquisition of the wear information of the conical section. At the same time, the rotation of the first threaded rod 24 drives the first bevel gear 25 to rotate. Through the meshing of the first bevel gear 25 and the second bevel gear 27, the second threaded rod 26 is driven to rotate. The second threaded rod 26 drives the abutting block 29 to move closer to the cyclone body 3 along the second chute 28. Finally, the two abutting blocks 29 are attached to the upper end of the connecting plate 31 to complete the fixation of the cyclone body 3 and ensure the stability of the equipment during the experiment. Step 3: Concentration adjustment: When it is necessary to increase the concentration of the liquid introduced into the cyclone body 3, start the second motor 65. The second motor 65 drives the third threaded rod 66 to rotate in reverse. The third threaded rod 66 drives the U-shaped long plate 63 to move closer to the feeding box 61 through the threaded connection with the ear block 74, changing the relative position of the through port 64 and the feed pipe 62 to connect the through port 64 and the feed pipe 62. At this time, the particles in the feeding box 61 will sequentially pass through the feed pipe 62, the through port 64, and the feeding port 69 and fall into the liquid storage tank 6. After adding the particles, start the second motor 65 again to make the third threaded rod 66 rotate forward, driving the U-shaped long plate 63 to move away from the feeding box 61. The inner bottom surface of the U-shaped long plate 63 blocks the through port 64 to stop the particle addition. The particles in the feeding box 61 are ore particles (quartz sand, iron ore particles). Step 4: Stirring, mixing and conveying: During the rotation of the third threaded rod 66, the driving gear 67 rotates accordingly. Through the meshing of the driving gear 67 and the driven gear 72, the stirring shaft 7 is driven to rotate. The stirring blades 71 on the stirring shaft 7 rotate accordingly to stir and mix the liquid and the newly added particles in the liquid storage tank 6. After mixing evenly, start the first water pump 8 to convey the mixed liquid in the liquid storage tank 6 to the cyclone body 3 through the feed pipe 32 for the experiment. Fifth step: After the cyclone body 3 is installed, the underflow pipe 36 at its bottom and the overflow pipe 35 at its top are both inserted into the circulation tank 9 and communicate with the inner cavity of the circulation tank 9. Start the second water pump 92, and the liquid separated by the cyclone in the circulation tank 9 can be transported to the liquid storage tank 6 to realize the recycling of the fluid and continuously provide a stable fluid source for the experiment. The material guiding plate 73 located below the feeding port 69 plays a role in guiding the particles to fall smoothly when the particles fall from the feeding port 69 into the liquid storage tank 6, which helps the particles to better blend into the liquid in the liquid storage tank 6; Sixth step: When the cyclone body 3 needs to be replaced, start the first motor in the bracket 2 again to reverse the first threaded rod 24. The reverse rotation of the first threaded rod 24 drives the slider 52 to move upward, and then drives the four push blocks 51 to move upward. At this time, under the elastic reset action of the spring 46, the four connecting blocks 44 are reset, driving the four housings 41 to be reset, so that the ultrasonic sensor 42 is separated from the surface of the conical section of the cyclone body 3. At the same time, the reverse rotation of the first threaded rod 24 drives the second threaded rod 26 to reverse through the bevel gear transmission, so that the two abutting blocks 29 move away from each other, releasing the limit lock on the connecting plate 31. Finally, remove the bolts on the flange 33, and the cyclone body 3 can be disassembled and replaced; Seventh step: Initial measurement: Before the experiment starts, the ultrasonic sensor 42 emits an ultrasonic signal to the conical section of the cyclone body 3. The ultrasonic wave is reflected back after encountering the inner wall of the conical section and is received by the sensor. The sensor calculates the distance from the sensor to the inner wall of the conical section according to the time difference between the transmitted and received ultrasonic signals, combined with the known propagation speed of the ultrasonic wave in the conical section material, and then obtains the initial wall thickness data of the conical section; During the experiment, with the flow of the fluid in the cyclone body 3 and the erosion and wear of the conical section by the particles, the wall thickness of the conical section will gradually change. The ultrasonic sensor 42 continuously emits and receives ultrasonic signals to monitor the change of the time difference of the reflected signal in real time. Since the change of the time difference is directly related to the change of the wall thickness of the conical section, according to the pre-set algorithm, the change of the time difference is converted into the change data of the wall thickness of the conical section. For example, if the time difference becomes smaller, it means that the wall thickness of the conical section becomes thinner, that is, wear has occurred; Each ultrasonic sensor 42 transmits the change data of the wall thickness of the conical section monitored in real time to the computer through a specific data transmission line (not detailed in the figure, but usually wired or wireless transmission methods can be used), and the researchers analyze the wear situation through data analysis.
