Description

Technical Field

[0001] This utility model relates to a flotation mechanism, and more particularly to a flotation mechanism for mineral processing. Background Technology

[0002] A mineral flotation machine is a mechanical device used for mineral separation. It is widely used in the mineral beneficiation process, especially in the processing of metallic and non-metallic minerals. Its working principle is based on the differences in the surface properties of minerals, especially the differences in the hydrophobicity and hydrophilicity of mineral surfaces. By using flotation agents, minerals are made to form different hydrophobic properties in water, causing them to float or sink in bubbles, thereby achieving mineral separation.

[0003] In existing flotation devices, such as the mica flotation device disclosed in CN221656852U, the lifting plate can be adjusted to a suitable position by bolts when flotating slurries with different mica concentrate contents, thereby facilitating the material feeding operation.

[0004] However, in the aforementioned mica flotation device, the stirring section is not easy to disassemble. If maintenance or replacement of the stirring section is required, a lot of time will be spent disassembling the stirring section, which will affect the working efficiency of the flotation device.

This removes the first bolts from the connecting block, allowing it to be removed from the connecting groove. This enables the separation of the first and second connecting heads, which are connected to a rotating shaft with a stirring plate mounted on it. Therefore, after the first and second connecting heads are separated, the second connecting head, rotating shaft, and stirring plate can be removed from the flotation mechanism, thus completing the flotation process.

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0034] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0035] This embodiment mainly describes the structure of a flotation mechanism for mineral processing, as detailed below:

[0036] like Figure 1-14 As shown, a flotation mechanism for mineral processing includes a base 1, on which a support frame 3 for placing a flotation cell 4 and a mounting frame 2 for mounting a drive device 5 are provided. A detachable connecting component 6 is provided at the output end of the drive device 5, and the top of the connecting component 6 is connected to the output end of the drive device 5. A rotating shaft 7 is provided at the bottom of the connecting component 6, and a stirring plate 9 is provided at the bottom of the rotating shaft 7. A pressure plate 8 with multiple through holes 82 is rotatably provided on the rotating shaft 7. The side wall of the pressure plate 8 can abut against the inner wall of the flotation cell 4, and the pressure plate 8 is located above the stirring plate 9. Finally, a foam scraping mechanism 10 for scraping foam is provided on the mounting frame 2.

[0037] Thus, when the flotation mechanism is working, firstly, the flotation cell 4 is installed on the support frame 3, and the stirring plate 9 is positioned in the flotation cell 4. Then, the ground slurry is added to the flotation cell 4. Next, the drive device 5 is started, causing the output end of the drive device 5 to drive the connecting component 6 and the rotating shaft 7 to rotate. In this way, the stirring plate 9 installed on the rotating shaft 7 can stir the slurry in the flotation cell 4, which can make the mineral particles in the slurry evenly distributed and can also make the slurry foam. Then, flotation reagents (such as collectors, frothers, depressants, and dispersants) are added to the slurry in the flotation cell 4, so that the minerals can better adhere to the foam. Because there is a pressure plate 8 with multiple through holes 82 on the rotating shaft 7 above the stirring plate 9, when the foam generated when the stirring plate 9 rotates floats upward, it will pass through the through holes 82 on the pressure plate 8, which can make the foam denser and thus improve the flotation efficiency. The high mineral adhesion effect on the foam, and the side wall of the pressure plate 8 abutting against the inner wall of the flotation cell 4, can make the pressure plate 8 stably located in the flotation cell 4. As the stirring plate 9 continuously agitates the slurry, the foam in the flotation cell 4 will also continuously rise in the flotation cell 4. At this time, the foam scraping mechanism 10 is activated. In this way, the foam can be scraped into the foam overflow trough on the flotation cell 4, thus collecting the foam in the flotation cell 4. In order to further improve the stability of the pressure plate 8 in the flotation cell 4, a limiting groove 41 is provided on the inner wall of the flotation cell 4, and a limiting block 81 that is slidably connected to the limiting groove 41 is provided on the side wall of the pressure plate 8. At the same time, in order to avoid the problem of the rotating shaft 7 not rotating smoothly due to the setting of the pressure plate 8, a bearing 83 is provided between the pressure plate 8 and the rotating shaft 7. The inner ring of the bearing 83 is connected to the rotating shaft 7, and the outer ring of the bearing 83 is connected to the pressure plate 8.

[0038] The connecting component 6 includes a first connector 61 connected to the drive device 5 at its top, and a second connector 62 at the bottom of the first connector 61. The bottom of the second connector 62 is connected to the rotating shaft 7. The bottom of the first connector 61 has multiple connecting grooves 611, and the outer wall of the first connector 61 has the same number of first connecting holes 612 as the connecting grooves 611, and the first connecting holes 612 communicate with the connecting grooves 611. The top of the second connector 62 has the same number of connecting blocks 621 as the connecting grooves 611, and the connecting blocks 621 are inserted into the connecting grooves 611. A first screw hole 622 is opened on the connecting block 621, and after the connecting block 621 is inserted into the connecting groove 611, the first screw hole 622 is located below the first connecting hole 612. Finally, a first bolt 13 is provided on the first connector 61, and the first bolt 13 passes through the first connecting hole 612 and is screwed into the first screw hole 622 on the connecting plate.

[0039] When it is necessary to replace the rotating shaft 7 and the stirring plate 9, the operator uses a tool (such as a wrench) to loosen the multiple first bolts 13 in sequence and unscrew the first bolts 13 from the first screw holes 622. This removes the first bolts 13 from the connecting block 621, allowing the connecting block 621 to be removed from the connecting groove 611. This allows the first connecting head 61 and the second connecting head 62, which are connected to the rotating shaft 7 and on which the stirring plate 9 is mounted, to be separated. Therefore, after the first connecting head 61 and the second connecting head 62 are separated, the second connecting head 62, the rotating shaft 7, and the stirring plate 9 can be removed from the flotation mechanism. After disassembling the agitator in the flotation machine, when connecting the second connector 62 to the first connector 61, the connecting block 621 is inserted into the connecting groove 611 on the first connector 61, and then the first bolt 13 is inserted into the first connecting hole 612. The operator then uses a tool to screw the first bolt 13 into the first screw hole 622 and tighten it. This completes the connection and fixation of the first connector 61 and the second connector 62, and also completes the installation of the rotating shaft 7 and the agitator 9 onto the flotation mechanism. The connection assembly 6 facilitates the disassembly and assembly of the agitator on the flotation mechanism, reducing the time required to replace the agitator and thus improving the efficiency of the flotation mechanism. To improve efficiency, the arrangement of multiple connecting slots 611 and connecting blocks 621 enhances the robustness of the connection between the first connector 61 and the second connector 62. To further improve torque transmission between the first and second connectors 62, the first connector 61 includes a first connecting post 614 with a polygonal third connecting hole 615 at its bottom. The second connector 62 includes a second connecting post 623 that matches the third connecting hole 615, and the second connecting post 623 is inserted into the third connecting hole 615. To improve the stability of the connecting blocks 621 within the connecting slots 611, each connecting block 621 is equipped with a spring-loaded telescopic rod. 14. A second limiting hole 613 is provided on the outer wall of the first connector 61 for the spring telescopic rod 14 to extend out. When the connecting block 621 is inserted into the connecting groove 611, the spring telescopic rod 14 is first compressed so that the spring telescopic rod 14 can enter the connecting groove 611. Then, the second connector 62 is pushed so that the connecting block 621 is inserted into the connecting groove 611. When the connecting block 621 enters the connecting groove 611 and the spring telescopic rod 14 is below the second limiting hole 613, the spring telescopic rod 14 can extend out from the second limiting hole 613. The first limiting hole 1051 can be aligned with the first screw hole 622, which makes it convenient to screw the first bolt 13 into the first screw hole 622.

[0040] Furthermore, the support frame 3 includes a first telescopic device 31 mounted on the base 1 and a bearing plate 32 mounted on the telescopic end of the first telescopic device 31. A fixing plate 33 is provided at both the left and right ends of the bearing plate 32, and a groove 34 is formed on each adjacent side wall of the two fixing plates 33. The flotation cell 4 is mounted on the bearing plate 32, and a sliding plate 35 is provided at the bottom of the flotation cell 4, which is slidably connected to the groove 34. Thus, when the flotation cell 4 is installed on the bearing plate 32, the sliding plate 35 at the bottom of the flotation cell 4 is inserted into the groove 34, and then the flotation cell 4 is pushed to move on the bearing plate 32, so that the flotation cell 4 can be positioned within the agitator. Below the mixing plate 9, the first telescopic device 31 is activated to extend the first telescopic device 31, allowing the flotation cell 4 to move upward until the mixing plate 9 is located in the flotation cell 4. After the flotation of the mineral is completed, the first telescopic device 31 is activated again to shorten the first telescopic device 31, allowing the flotation cell 4 to move away from the mixing plate 9. Then the flotation cell 4 is removed from the support plate 32. The support frame 3 facilitates the installation of the flotation cell 4. In order to limit the movement of the flotation cell 4 on the support plate 32, a limiting plate 36 is provided on the inner side of the support plate 32, and the left and right ends of the limiting plate are respectively connected to the fixing plate 33.

[0041] The mixing disc 9 includes a connecting seat 16 that is screwed to the rotating shaft 7, which facilitates the assembly and disassembly of the mixing disc 9 and the rotating shaft 7. A mounting seat 17 is provided at the bottom of the connecting seat 16, and multiple mounting grooves 171 are formed at the bottom of the mounting seat 17. A second screw hole 174 is formed at the top of each mounting groove 171. A mounting block 172 is provided in each of the multiple mounting grooves 171, and a second connecting hole aligned with the second screw hole 174 is formed on each mounting block 172. A second bolt 173 is also provided on each mounting block 172. The second bolts 173 all pass through the second connecting holes and are screwed into the second screw holes 174. Finally, a stirring blade 15 is set on the outer wall of each of the multiple mounting blocks 172. Thus, when it is necessary to disassemble the stirring blade 15, a worker can use tools to unscrew the second bolts 173 from the second screw holes 174. In this way, the mounting block 172 can be removed from the mounting groove 171. Since the stirring blade 15 is connected to the mounting block 172, the disassembly of the stirring blade 15 is completed as the mounting block 172 is removed. This facilitates the maintenance and replacement of the stirring blade 15.

[0042] The skimming mechanism 10 includes a first adjusting groove 102 formed on the side wall of the mounting frame 2 and a second telescopic device 103 installed in the first adjusting groove 102. A fixing block 101 is provided at the telescopic end of the second telescopic device 103, and a mounting plate 105 with a second adjusting groove 106 formed on the side wall is provided on the fixing block 101. At the same time, a plurality of first limiting holes 1051 are evenly formed on the mounting plate 105 at the top of the second adjusting groove 106. A motor 104 is provided in the second adjusting groove 106, and the motor 104 is engaged with the first limiting holes 1051 by fixing bolts 1052. A connecting rod 107 is fixed in the second adjusting tank 106, and a connecting rod 107 is installed above the flotation tank 4 at the output end of the motor 104. A scraper 108 is installed on the connecting rod 107. When the motor 104 starts, its output end drives the connecting rod 107 and the scraper 108 to rotate. Because the connecting rod 107 is located above the flotation tank 4, the second telescopic device 103 needs to be activated to allow the scraper 108 to contact the foam in the flotation tank 4. As the motor 104 rotates, the scraper 108 scrapes the foam in the flotation tank 4, thus allowing the foam to escape from the flotation tank. The foam overflows from the froth overflow tank on the froth cell 4, facilitating the collection of foam in the froth cell 4. When it is necessary to move the position of the connecting rod 107 on the froth cell 4, the position of the motor 104 installed in the second adjusting tank 106 can be changed, thus improving the practicality of the skimming mechanism 10. To improve the stability of the connecting rod 107 during rotation, a telescopic support rod 11 is provided on the support frame 3 at the end of the connecting rod 107 away from the motor 104. A connecting cylinder 12 for connecting to the connecting rod 107 is also provided on the telescopic support. This allows for the adjustment of the position of the motor 104 in the second adjusting tank 106. The position of the connecting rod 107 is adjusted by the position in the slot 106. Therefore, in order to facilitate the use of the telescopic support rod 11, the telescopic support rod 11 is slidably installed on the support frame 3. In order to improve the aesthetics of the mounting frame 2, the second telescopic device 103 is installed in the first adjustment slot 102. In order to ensure the reliability of torque transmission between the output end of the motor 104 and the connecting rod 107, a third connecting post 1041 with a polygonal arrangement is provided at the output end of the motor 104, and a fourth connecting hole 121 matching the third connecting post 1041 is provided at the end of the connecting rod 107 that is connected to the output end of the motor 104.

[0043] Furthermore, the connecting cylinder 12 includes a cylinder 122 mounted on the telescopic support rod 11, and a third connecting head 123 is rotatably disposed in the cylinder 122, and the third connecting head 123 is movable in the cylinder 122. Then, a fifth connecting hole 126 matching the connecting rod 107 is opened on the side wall of the third connecting head 123. Finally, a telescopic guide rod 124 connected to the third connecting head 123 is disposed in the cylinder 122, and a spring 125 is sleeved on the telescopic guide rod 124. One end of the spring 125 is connected to the third connecting head 123 and the other end is connected to the inner wall of the cylinder 122.

[0044] When installing the connecting rod 107, first insert the end of the connecting rod 107 without the fourth connecting hole 121 into the fifth connecting hole 126 of the third connecting head 123. Then push the connecting rod 107 so that the third connecting head 123 can move in the cylinder 122 and compress the telescopic guide rod 124 and the spring 125 until the fourth connecting hole 121 on the other end of the connecting rod 107 can be connected to the third connecting post 1041 on the output end of the motor 104. In this way, the setting of the connecting cylinder 12 facilitates the installation of the connecting rod 107, and the setting of the telescopic guide rod 124 makes the spring 125 extend or shorten more smoothly.
