Description

Technical Field

[0001] The invention belongs to the technical field of spiral separators, and in particular relates to a particle size visualization online analysis system for a spiral separator. Background Art

[0002] The spiral separator is a device that uses water flow to drive mineral particles (coal particles, copper ore particles, etc.) to move radially on a spiral trough and classify the minerals. In the process of water flow driving the minerals to spiral down, the mineral particles are affected by the composite force field of gravity, centrifugal force, fluid resistance, etc., and the minerals are distributed in different positions of the chute according to their density, that is, high-density minerals are on the inner edge side, and low-density minerals are on the outer edge side. Finally, a device is used at the tail of the spiral trough to classify and discharge the minerals of corresponding density.

[0003] Currently, the separators commonly used in laboratories are essentially all equipped with a single spiral flute with only one parameter (the flutes are welded to other parts). Furthermore, when studying the separator's sorting performance, it is necessary to quickly and evenly sample a small amount of material from the discharge device at the end of the circulating spiral flute (e.g., quickly intercepting and classifying mineral particles within 4-6 seconds of each discharge port). The proportion of different particle sizes and density levels within the sampled minerals is then analyzed. However, in actual experimental operations, a variety of factors can lead to inaccurate experimental results, such as: Question 1: At present, the spiral separators used in the field of scientific research are usually designed according to the research direction. During the design process, the cross-sectional shape, inclination angle, pitch and other parameters of the spiral groove are determined. In order to facilitate the experiment and ensure the stability of the experimental table, the spiral groove is usually welded together with the feeding system and other mechanisms. When the research direction needs to be adjusted after the design and processing is completed, it needs to be redesigned and produced.

[0004] Question 2: When conducting experiments on sorting yield, it is necessary to cut and sample at a specific location on the cutting device at the tail of the spiral trough. The cutting time needs to be calculated based on the flow rate of the minerals in the spiral trough, such as cutting 4 to 6 seconds of slurry. Because the sorting machine needs to continue to circulate during sampling, during normal circulation, the classified slurry flowing out of the discharge device at the tail of the spiral trough flows directly back into the mixing barrel for re-mixing and circulation. Therefore, to ensure the accuracy of the experimental data, it is necessary to quickly cut samples from each discharge port of the tail receiving device at the same time, such as collecting 6 seconds of slurry from the six discharge ports at the tail at the same time. However, currently commonly used sorting machines are unable to quickly and evenly complete sampling at the same time and for the same duration.

[0005] Question 3: Currently, the feed inlets of spiral separators are all fixed structures. When conducting experiments on the sorting effects of different numbers of turns, the top feed mechanism is fixed and it is impossible to implement the middle position feeding method (the feeding position is not limited and the flow rate, flow rate and other parameters are the same as those of the raw material inlet). Even if the slurry is directly led to the specified position through a hose, the accuracy of the experimental results will still be deviated due to the different outflow patterns.

[0006] Question 4: When analyzing the samples taken, it is necessary to analyze the particle size ratio and density ratio data of the samples. The density ratio is usually obtained by a small floating and sinking method. However, due to the small number of some samples that cannot be screened, the particle size ratio data of the samples taken cannot be obtained. In actual experiments, the particle size ratio data will be measured on the same batch of original mineral particles, so there will definitely be differences between the measured particle size screening data and the actual value of the sample taken from the sorting machine.

When the sliding plate 50 is driven to slide backward by the push-pull rod 49, the six sampling barrels 51 are located above the mixing tank 20. At this time, the materials output by the six discharge pipes 7 all enter the interior of the mixing tank 20; when the sliding plate 50 is driven to slide forward by the push-pull rod 49, the six sampling barrels 51 are respectively located above the six external sampling cavities of the external sampler 8. At this time, the materials output by the six discharge pipes 7 respectively enter the six external sampling cavities of the external sampler 8 and are finally output independently to the outside.

[0045] A screw pump 53 is installed below the mixing tank 20. Its power shaft is fixedly connected to the output shaft of the conveying motor 52, which drives the screw pump 53. The inlet of the screw pump 53 is connected to the output pipe at the lower end of the mixing tank 20. A main conveying pipe 54 is installed at the outlet of the screw pump 53. A first conveying branch pipe 55 and a second conveying branch pipe 56 are installed at the end of the main conveying pipe 54 away from the screw pump 53. The first conveying branch pipe 55 extends into the mixing tank 20 and is equipped with a first valve 57. The second conveying branch pipe 56 is equipped with a second valve 58 and a flowmeter 59.

A mobile feeder 61 is fixedly provided at the end of the mobile feed pipe 60 away from the second conveying branch pipe 56, and a fixed feeder 63 is fixedly provided at the end of the fixed feed pipe 62 away from the second conveying branch pipe 56. The fixed feeder 63 is fixedly provided at the upper entrance of the spiral groove 4. Two fixing clips 64 are fixedly provided on the mobile feeder 61, and a locking bolt 65 is screwed onto one of the fixing clips 64, and a knob is fixedly provided on the outer end of the locking bolt 65. When the mobile feeder 61 is provided inside the spiral groove 4, the two fixing clips 64 are provided on both sides of the outer wall of the spiral groove 4, and the locking bolt 65 is tightly abutted against the outer wall of the spiral groove 4, thereby fixing the mobile feeder 61 to the spiral groove 4. When the locking bolt 65 is loosened, the position of the mobile feeder 61 can be adjusted. After the adjustment is completed, the locking bolt 65 is tightened again to fix the mobile feeder 61.

[0046] The working principle of the present invention is: When conducting the experiment, first inject a certain amount of clean water into the mixing tank 20, then control the stirring motor 21 and the conveying motor 52 to start, and at the same time open the first valve 57 and the second valve 58, and control each material blocking slide 35 to be located at the upper end opening of the sampling and equalizing cavity 30, and close the sampling and equalizing cavity 30 inside each discharge pipe 7 to prevent clean water from entering the reduction sampler 31 and the sedimentation observer 40; at the same time, control the six sampling tubes 51 on the sliding plate 50 to be located above the mixing tank 20; and make the dial plate 26 on the cutter 22 contact the inner wall of the spiral groove 4 when rotating, so that all the materials inside the spiral groove 4 pass through the outer arc plate 24 and the inner arc plate 23 of the cutter 22 when passing through the cutter 22 and are finally output from the lower end outlet of the spiral groove 4; at the same time, the valves on the fixed feeder 63 and the mobile feeder 61 are opened.

[0047] The clean water inside the mixing tank 20 enters the screw pump 53, and under the action of the screw pump 53, enters the conveying main pipe 54, the first conveying branch pipe 55, the second conveying branch pipe 56, and the fixed feed pipe 62. In this way, part of the clean water directly flows back to the mixing tank 20, and part of the clean water enters the spiral groove 4 from the fixed feeder 63, and the remaining part of the clean water enters the spiral groove 4 from the mobile feeder 61. The clean water entering the spiral groove 4 enters the six discharge pipes 7 and finally flows back to the mixing tank 20, thereby cleaning the inside of each component.

[0048] After the clean water circulates normally throughout the system, the stirring motor 21 is controlled to continue to operate, the conveying motor 52 is stopped, and the first valve 57 is closed. Then, the mineral particles to be studied and tested are added to the stirring tank 20. The stirring motor 21 drives the stirring blades to stir the stirring tank 20, thereby mixing the mineral particles and the clean water into a slurry.

[0049] After the slurry is stirred evenly, the conveying motor 52 is controlled to start, the valve on the mobile feeder 61 is closed, and the opening of the first valve 57 is adjusted according to the reading of the flow meter 59. The conveying motor 52 drives the screw pump 53 to operate, so that the stirred slurry is conveyed to the interior of the fixed feeder 63 through the conveying main pipe 54, the second conveying branch pipe 56, and the fixed feeder pipe 62, and is introduced into the upper end entrance of the spiral trough 4 through the fixed feeder 63. The slurry flows down the spiral trough 4 and flows into the five discharge pipes 7, and flows back to the interior of the mixing tank 20 along the discharge pipe 7 to continue stirring, thereby completing the circulation of the slurry.

[0050] When slurry sampling and analysis is required, the push-pull rod 49 is pushed forward, causing the sliding plate 50 to slide forward. The six sampling tubes 51 are positioned above the six external sampling chambers of the external sampler 8. The slurry output from the five discharge pipes 7 then enters the five external sampling chambers of the external sampler 8 and is ultimately independently output to dedicated sampling dishes. When sampling is complete, the push-pull rod 49 is pulled backward again, and the six sampling tubes 51 are repositioned above the mixing tank 20. The slurry output from the five discharge pipes 7 then re-enters the mixing tank 20 for circulation.

[0051] When sampling and analysis of the slurry at a specific location in the spiral trough 4 is required, the paddle 26 on the cutter 22 is moved so that the end of the paddle 26, away from the cutter 22, is located in the middle of the inner side of the spiral trough 4. This causes a portion of the slurry to flow into the cutter tube 27 under the action of the paddle 26 and the inner arc plate 23 of the cutter 22, and then into a designated discharge tube 7. The pull rod is then pushed forward again, so that the slurry flowing out of the designated discharge tube 7 enters the designated sampling dish. After sampling is completed, the push-pull rod 49 is pulled backward again, and the slurry output from the discharge tube 7 re-enters the mixing tank 20 for circulation.

[0052] When studying the feeding and sorting effects at a specific location on the spiral trough 4, the fixed feeder 63 at the upper entrance of the spiral trough 4 cannot be used. Instead, a mobile feeder 61 is required at that specific location on the spiral trough 4. Turn off the conveying motor 52 and the second valve 58. At the same time, close the valve on the fixed feeder 63 and open the valve on the mobile feeder 61. Clamp the two fixing clips 64 on the mobile feeder 61 to the outer wall of the specific location on the spiral trough 4 and tighten the locking bolts 65. This secures the mobile feeder 61 to the specific location on the spiral trough 4. Then, turn on the conveying motor 52 and the second valve 58. Simultaneously, move the paddle 26 until it contacts the inner wall of the spiral trough 4. The mobile feeder 61 then feeds the slurry into the specific location on the spiral trough 4, where it flows downward and into the five discharge pipes 7. Then, push the push-pull rod 49 forward again to discharge the slurry from the discharge pipes 7 into the sampling dish. After the sampling is completed, the push-pull rod 49 is pulled backward again, and the slurry output from the discharge pipe 7 re-enters the interior of the stirring tank 20 for circulation.

[0053] When it is necessary to perform particle size analysis on the slurry inside each feed cavity of the cut-off port 6, first insert the two sealing plates 41 at the lower end of the sedimentation observer 40 to close the outlet at the lower end of the sedimentation observer 40. Then open the rising water flow fine-tuning valve 43 on the water inlet pipe to allow water to continuously flow out of the overflow pipe 44. Then turn on the fill light 45 and the camera 46, and slowly move the material blocking connecting rod 38. The material blocking connecting rod 38 drives all the material blocking levers 37 to rotate, the material blocking levers 37 drive the material blocking ring 36 to rotate, and the material blocking ring 36 drives the material blocking slide 35 to rotate, so that the material blocking slide 35 is detached from the upper end opening of the sampling and equalizing cavity 30. After being acted upon by the spiral guide vanes 28, the slurry inside the discharge pipe 7 is evenly distributed into ten equal distribution chambers. One-third of the slurry that enters the frontmost equal distribution chamber enters the reduced sampling chamber. This portion of slurry enters the particle spreader 39 through the sampling port for dispersion. The dispersed slurry then enters the sedimentation observer 40. At this point, one-thirtieth of the slurry inside the discharge pipe 7 enters the sedimentation observer 40. It is then observed whether slurry particles fall into the sedimentation observer 40 corresponding to each sampling port. The water flow velocity inside the sedimentation observer 40 is changed by adjusting the rising water flow fine-tuning valve 43, thereby controlling the sedimentation velocity of the slurry particles inside the sedimentation observer 40 so that the camera 46 can identify the internal slurry particles. After identification, the camera 46 outputs the particle size ratio data. After the analysis is complete, the blocking rod 38 is moved again, causing the blocking slide 35 to re-seal the upper opening of the sampling and averaging chamber 30, and the rising water flow fine-tuning valve 43 is closed to stop the water supply. The sealing plate 41 on the upper side of the sedimentation observer 40 is then pulled outward, allowing the slurry particles inside the sedimentation observer 40 to enter the outlet portion at the lower end of the sedimentation observer 40. The upper sealing plate 41 is then inserted and the lower sealing plate 41 is pulled out, and the observed slurry particle samples are taken out of the outlet portion at the lower end of the sedimentation observer 40.

[0054] Since the slurry inside the discharge pipe 7 is not full, and the pipe is a three-phase flow of gas, liquid, and solid, the reduced diameter section can guide the slurry to the area of ​​the spiral guide vanes 28. The spiral guide vanes 28 and the reduced diameter section work together to change the flow direction and flow rate of the slurry, making the slurry passing through this structure evenly distributed and reducing the flow rate, so that the next structure can uniformly sample.

[0055] The slurry inside the discharge pipe 7 can be evenly divided into ten equal parts by the divider 29 , and then one-tenth of the slurry is evenly divided into three equal parts again by the reduction sampler 31 , and this one-thirtieth of the slurry is drained into the particle disperser 39 .

[0056] By providing the blocking slide 35, the upper opening of the sampling and averaging cavity 30 can be sealed when particle size analysis is not required, thereby preventing the slurry from entering the interior of the sub-sampler 31. When the blocking slide 35 is opened, a large gap is maintained between the blocking slide 35 and the sub-sampler 31, ensuring that the slurry blocked by the blocking slide 35 can flow out of the other averaging cavities, thereby preventing the slurry blocked by the blocking slide 35 from entering the interior of the sub-sampler 31 and affecting the experimental results.

[0057] By gradually narrowing the internal thickness and widening the internal width of the particle spreader 39 from top to bottom, the internal gap gradually narrows from top to bottom and the spread area gradually increases from top to bottom, so that the slurry particles collected in the reduction sampler 31 are evenly spread into a layer for easy recognition by the camera.

[0058] By adjusting the opening of the rising water flow fine-tuning valve 43, the water flow speed can be adjusted so that the rising speed of the water flow and the falling speed of the particles offset each other, and the settling speed of the particles is automatically reduced to facilitate recognition by the camera 46.

[0059] By alternately opening and closing the two sealing plates 41 , the slurry particles that have settled to the bottom of the sedimentation observer 40 can be discharged layer by layer, ensuring that the water in the sedimentation observer 40 does not flow out completely when the sample is finally collected.

[0060] The spiral trough 4 of the present invention is designed to be replaceable. A support block 18 is placed at the lower end of the spiral trough bracket 2, allowing a gravity lift tool to directly reach under the spiral trough bracket 2 and lift it. The spiral trough 4 and the spiral trough bracket 2 are fixed to the fixed frame 1 using fixing plates 19 and bolts, allowing for convenient and rapid replacement of the spiral trough 4 for different research needs.
