Description

Technical Field

[0001] The present invention relates to the technical field of high-calcium-magnesium and high-slime zinc carbonate flotation devices, and particularly to a high-calcium-magnesium and high-slime zinc carbonate flotation device and its usage method. Background Technique

[0002] Flotation recovery is a beneficiation method. It mainly utilizes the differences in the physical and chemical properties of the mineral surface, especially the wettability of the mineral surface. Usually, after the ore is ground, specific flotation reagents are added. The useful minerals that are easily carried by the foam will adhere to the bubbles and float up with the foam to be collected, while the gangue minerals remain in the pulp. In this way, the separation of the useful minerals and the gangue minerals is achieved, and the purpose of recovering the useful minerals is realized. It is widely used in the beneficiation of various minerals such as non-ferrous metals and precious metals.

[0003] When some existing high-calcium-magnesium and high-slime zinc carbonate flotation devices mix and stir the pulp and reagents, there may be a situation of uneven mixing, which greatly reduces the flotation efficiency. Because the mineral particles do not come into sufficient contact with the collector and cannot be effectively modified to be hydrophobic, the adhesion to the bubbles is hindered, and the uneven distribution of the foaming agent results in poor quantity and quality of the generated bubbles, poor stability, and the unstable foam layer easily causes the attached minerals to fall back, seriously hindering the flotation process. Summary of the Invention

Moving plates are fixedly connected to the front sides of the two positioning blocks.

[0016] The present invention has the following beneficial effects:

[0017] (1) Through the mixing mechanism of the present invention, the motor is started. The motor drives the first rotating shaft to rotate. When the first rotating shaft rotates, it drives the second stirring blade to rotate. When the first rotating shaft rotates, it drives the fixing plate to rotate. When the fixing plate rotates, it drives the connecting rod to move. When the connecting rod moves, it drives the connecting plate to rotate. When the connecting plate rotates, it drives the first stirring blade and the internal thread block to rotate. Through the mixing mechanism, the pulp and the reagent can be deeply blended, avoiding the problem of uneven mixing easily caused by conventional single rotary stirring, ensuring the uniform distribution of the pulp and the reagent in the entire stirring space, greatly improving the contact efficiency between the reagent and the mineral particles, not only significantly increasing the collision probability between the two, but also prolonging the residence time of the mineral particles in the stirring area, making their movement trajectories tortuous and variable, thereby enhancing the adsorption effect of the reagent on the surface of the mineral particles. It can also make the reagent and the pulp at the bottom of the mixing barrel participate in the mixing process, avoiding material waste, accelerating the overall stirring process, and making the stirring effect more uniform.

[0018] (2) Through the flotation mechanism of the present invention, the fan is started. The fan absorbs air through the first connecting pipe. The absorbed air enters the first connecting pipe after being filtered by the filter box. The filtered air enters the aeration pipe through the second connecting pipe and is finally discharged through the aeration micropores. Then, the second motor is started. The second motor drives the second rotating shaft to rotate. When the second rotating shaft rotates, it drives the third rotating shaft to rotate through the pulley and the belt. When the second and third rotating shafts rotate, they drive the third stirring blade to rotate. Finally, the third motor is started. The third motor drives the fourth rotating shaft to rotate. When the fourth rotating shaft rotates, it drives the scraper to rotate. Through the flotation mechanism, the pulp in the flotation tank is stirred to form a continuous dynamic cycle inside the pulp, not only effectively counteracting the sedimentation trend of the mineral particles under the action of gravity, ensuring that all kinds of mineral particles are always evenly suspended in the pulp, enabling them to have the opportunity to fully contact with the bubbles at any time during the entire flotation process and avoiding the reduction of flotation efficiency caused by particle sedimentation, but also promoting the highly uniform dispersion of the flotation reagent in the pulp space, ensuring that the reagent molecules can fully interact with the surface of the mineral particles, maintaining the dynamic balance of adsorption and desorption between the reagent and the mineral, thereby comprehensively improving the accuracy, selectivity and overall effectiveness of flotation and increasing the flotation efficiency.

[0019] (3) Through the disassembly mechanism of the present invention, the moving plate is moved. The moving plate drives the positioning block to move. When the positioning block moves, the spring contracts, so that the positioning block moves into the spring, and thus the positioning block disengages from the positioning groove. Then, the moving plate is moved in a direction away from the filter box, so that the moving plate drives the fixing frame to move through the positioning block. The filter plate can be easily disassembled and installed through the disassembly mechanism, ensuring that when the filter plate is blocked, damaged, or requires regular cleaning and maintenance, the disassembly operation can be quickly carried out and the installation can be efficiently completed for reuse. It effectively avoids the interruption or instability of the air supply caused by the filter plate failure, ensures that the gas continuously and stably enters the pulp evenly and stably through the aeration micropores on the aeration pipe, maintains the stability and sufficiency of the gas content in the pulp, and keeps the gas-liquid-solid three-phase mixing in the flotation process in a good state all the time. This is conducive to the full contact and attachment of mineral particles and bubbles, promotes the smooth progress of flotation separation, and further ensures the efficiency and stability of the flotation operation, improving the quality and recovery rate of flotation products.

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] A usage method of a high-calcium-magnesium and high-slime zinc carbonate flotation device includes the following steps.

[0037] S1. Start the motor 22. The motor 22 drives the rotation of the first rotating shaft 23. When the first rotating shaft 23 rotates, it drives the rotation of the second stirring blade 211. When the first rotating shaft 23 rotates, it drives the rotation of the fixing plate 29. When the fixing plate 29 rotates, it drives the movement of the connecting rod 210. When the connecting rod 210 moves, it drives the rotation of the connecting plate 27. When the connecting plate 27 rotates, it drives the rotation of the first stirring blade 28 and the internal thread block 26.

[0038] S2. Start the blower 32. The blower 32 absorbs air through the first connecting pipe 34. The absorbed air is filtered by the filter box 33. The filtered air enters the aeration pipe 36 through the second connecting pipe 35 and is finally discharged through the aeration micropores 37. Start the second motor 38. The second motor 38 drives the rotation of the second rotating shaft 39. When the second rotating shaft 39 rotates, it drives the rotation of the third rotating shaft 310 through the belt pulley 312 and the belt 313. When the second rotating shaft 39 and the third rotating shaft 310 rotate, they drive the rotation of the third stirring blade 311.

[0039] S3. Move the moving plate 47. When the moving plate 47 is moved, it drives the movement of the positioning block 45. When the positioning block 45 moves, it drives the contraction of the spring 44. Then move the fixing frame 41. When the fixing frame 41 moves, it drives the movement of the filter plate 42.

[0040] In use, the pulp is put into the interior of the mixing barrel 21 through the feeding pipe 1 212, and then appropriate amounts of various reagents are successively put into the mixing barrel 21 through the feeding pipe 2 213, so that the reagents and the pulp are evenly mixed. During the mixing process of the pulp and the reagents, the reagents fully act on zinc carbonate minerals, calcium and magnesium minerals, and slime, etc. The inhibitor adsorbs on the surface of the calcium and magnesium minerals, reducing their floatability; the dispersant disperses the slime to prevent it from coating the zinc carbonate minerals; the collector selectively adsorbs on the surface of the zinc carbonate minerals, making them hydrophobic. When mixing the pulp and the reagents, the motor 22 is started. The motor 22 drives the rotating shaft 1 23 to rotate. When the rotating shaft 1 23 rotates, it drives the stirring blade 2 211 to rotate, so as to mix and stir the pulp and the reagents through the stirring blade 2 211. When the rotating shaft 1 23 rotates, it drives the fixing plate 29 to rotate. When the fixing plate 29 rotates, it drives the connecting rod 210 to rotate around the rotating shaft 1 23. When the connecting rod 210 rotates, it drives the connecting plate 27 to rotate. When the connecting plate 27 rotates, the stirring blade 1 28 and the internal thread block 26 rotate. When the internal thread block 26 rotates, under the cooperation with the thread groove on the external thread sleeve 25, the internal thread block 26 can move up and down on the external thread sleeve 25 while rotating. Thus, the internal thread block 26 in turn drives the connecting plate 27 and the stirring blade 1 28 to move up and down while rotating, so as to further enhance the mixing uniformity of the pulp and the reagents through the stirring blade 1 28, avoiding the layering phenomenon that may occur due to only rotational stirring, and enabling the pulp and the reagents to be fully and evenly distributed throughout the mixing barrel 21. The valve 1 215 is opened, and the mixed pulp and reagents enter the flotation cell 31 through the discharge pipe 214.

[0041] After the mixed pulp and reagent enter the flotation cell 31, start the blower 32. The blower 32 absorbs air through the first connecting pipe 34. The absorbed air enters the first connecting pipe 34 after being filtered by the filter box 33. By filtering the air, it is avoided that dust, moisture, etc. contained in the air enter the interior of the blower, causing damage to the blower or blocking the subsequent pipelines, thereby affecting the flotation efficiency. The filtered air enters the aeration pipe 36 through the second connecting pipe 35 and is finally discharged evenly into the pulp through the aeration micropores 37, so that the pulp forms tiny bubbles, enabling the zinc carbonate minerals to adhere to the bubbles and then float with the bubbles to form a foam layer. At the same time as starting the blower 32, also start the second motor 38. The second motor 38 drives the second rotating shaft 39 to rotate. When the second rotating shaft 39 rotates, it drives the third rotating shaft 310 to rotate through the pulley 312 and the belt 313. When the second rotating shaft 39 and the third rotating shaft 310 rotate, they drive the third stirring blade 311 to rotate, thereby stirring the pulp in the flotation cell 31. Thus, the third stirring blade 311 stirs the pulp in the flotation cell 31, causing the mineral particles to move continuously in the pulp, increasing the probability of their collision with the bubbles, increasing the number of collisions between the mineral particles and the bubbles several times per unit time, increasing the possibility of the zinc carbonate minerals adhering to the bubbles, and further improving the flotation efficiency. Finally, start the third motor 315. The third motor 315 drives the fourth rotating shaft 316 to rotate. When the fourth rotating shaft 316 rotates, it drives the scraper 317 to rotate. When the scraper 317 rotates, it scrapes the bubbles floating on the surface of the pulp in the flotation cell 31, so that the bubbles enter the collection box 318 through the guide plate 319 for collection, while the gangue minerals remain in the flotation cell 31, thus realizing the preliminary flotation separation of zinc carbonate. When the flotation is completed, open the second valve 321, and the remaining gangue minerals and waste water in the flotation cell 31 are discharged through the waste discharge pipe 320.

[0042] Move the moving plate 47. The moving plate 47 drives the positioning block 45 to move. When the positioning block 45 moves, it drives the spring 44 to contract, so that the positioning block 45 moves into the spring 44, and then the positioning block 45 disengages from the positioning groove 46. Then move the moving plate 47 in the direction away from the filter box 33, so that the moving plate 47 drives the fixing frame 41 to move through the positioning block 45, so that the fixing frame 41 disengages from the filter box 33, and the disassembly of the filter plate 42 can be completed. When installing the filter plate 42, first make the positioning block 45 drive the spring 44 to contract through the moving plate 47, so that the positioning block 45 slides into the chute 43, and then slide the fixing frame 41 into the filter box 33. Release the moving plate 47. When the positioning block 45 and the positioning groove 46 are on the same horizontal line, the spring 44 resets and stretches under its own elastic force, so that the spring 44 drives the positioning block 45 to move, and then the positioning block 45 enters the positioning groove 46, thus completing the installation of the filter plate 42, making the filter plate 42 easy to disassemble and install, and thus facilitating the cleaning, maintenance and replacement of the filter plate 42, effectively avoiding the interruption or instability of gas supply caused by the failure of the filter plate 42, and ensuring that the gas continuously and stably flushes into the pulp, maintaining the stability and sufficiency of the gas content in the pulp.
