[0001] The present invention belongs to the technical field of flotation machines, specifically a circular flotation machine for efficient separation and sorting. Background Art

[0002] In the field of mineral flotation, as the core equipment, the flotation machine undertakes the key task of separating and extracting useful minerals from ores. The scraping plate is an indispensable important component in the flotation machine. With the continuous expansion of the scale of mining and the increasing amount of ore processed, the flotation machine is always in a state of high-intensity continuous operation.

[0003] For example, the invention patent with the publication number CN113102121B discloses a flotation machine that is easy to clean, including: a stirring barrel, the top of the stirring barrel is open, at least one concentrate discharge port is arranged at the open end of the stirring barrel, the stirring barrel is arranged in a horn shape that gradually narrows from the middle to the bottom, and a tailing discharge pipe is fixedly connected to the bottom of the stirring barrel; a feeding flotation component that drives the concentrate in the flotation machine to move towards the open end of the stirring barrel; a driving component that drives the concentrate to move towards the concentrate discharge port; and a liquid level detector that is fixedly connected to the open end of the stirring barrel and detects the liquid level of the concentrate flotation in real time. By the cooperation of the feeding flotation component and the driving component, the working efficiency of the flotation machine is improved, comprehensive adsorption is realized during the mineral flotation process, the overall working efficiency is improved, and the phenomenon that too much drug is adsorbed on the inner surface of the stirring tank is reduced, and the service life of the flotation machine is prolonged.

[0004] In the above technology, although the overall working efficiency can be improved, various mineral particles, flotation reagent residues, and impurities in the pulp are extremely easy to adhere to the surface of the driving blades. With the accumulation of these attachments over time, the surface roughness of the driving blades continues to increase, and the originally smooth scraping plane becomes uneven. In this way, during the scraping process, the effective contact area between the driving blades and the foam layer decreases, and the scraping efficiency is greatly reduced, resulting in a large amount of foam containing useful minerals not being able to be scraped out of the flotation cell in time, seriously affecting the flotation recovery rate.

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] As Figures 1 to 8 shown, the high-efficiency sorting circular flotation machine of the present invention includes a flotation machine body, a driving mechanism, a control mechanism and a cleaning mechanism.

[0037] The flotation machine body includes a storage cylinder 1 and a discharge plate 2. The inside of the storage cylinder 1 provides a accommodation space for the flotation slurry. The radial outer wall of the storage cylinder 1 has a discharge port. The discharge plate 2 is rotatably arranged inside the storage cylinder 1. When injecting air into the slurry to generate bubbles, the discharge plate 2 is rotated along the axis of the storage cylinder 1 to scrape the foam inside the storage cylinder 1 and discharge the foam from the discharge port, realizing the flotation operation of minerals.

[0038] The driving mechanism includes an installation frame 4, a driving motor 5 and a transmission shaft 6. The installation frame 4 is fixedly installed on the upper end face of the storage cylinder 1. There is an opening at the upper end of the storage cylinder 1, and the installation frame 4 is located above the opening.

[0039] The driving motor 5 is fixedly installed on the upper end surface of the mounting bracket 4, and the output shaft of the driving motor 5 is connected to the transmission shaft 6. The driving motor 5 is used to control the rotation of the transmission shaft 6, and the rotation of the discharge plate 2 is controlled by the transmission shaft 6. Among them, a plurality of discharge plates 2 are arranged in a ring along the axis of the transmission shaft 6.

[0040] The control mechanism includes a mounting shaft 13 and a mounting cylinder 10. The mounting shaft 13 is fixedly installed on the radial outer wall of the transmission shaft 6, and the axis of the mounting shaft 13 is perpendicular to the axis of the transmission shaft 6. During the process of rotating the transmission shaft 6, the mounting shaft 13 is driven to rotate synchronously.

[0041] The mounting cylinder 10 is rotatably connected to the mounting shaft 13 through an elastic member. The other end of the mounting cylinder 10 is fixedly connected to the outer wall of the discharge plate 2. One end of the mounting shaft 13 extends into the interior of the mounting cylinder 10, and a torsion spring is arranged on the outer wall of the mounting shaft 13. The other end of the torsion spring is connected to the inner wall of the mounting cylinder 10.

[0042] Among them, the elastic force of the torsion spring controls the mounting cylinder 10, so that the discharge plate 2 always has a tendency to be parallel to the liquid level inside the storage cylinder 1.

[0043] The cleaning mechanism includes a transfer box 9 and a cleaning brush 11. The transfer box 9 is arranged inside the storage cylinder 1, and the cleaning brush 11 is fixedly installed on the bottom surface of the transfer box 9. Among them, when the discharge plate 2 rotates to the horizontal state, rotating the transmission shaft 6 drives the discharge plate 2 to pass through the bottom of the cleaning brush 11, so as to wipe the side of the discharge plate 2 that pushes the foam through the cleaning brush 11, thereby wiping the sticky material and dripping it into the interior of the storage cylinder 1, realizing the cleaning of the discharge plate 2, keeping the outer wall of the discharge plate 2 clean during the flotation process, and improving the quality of flotation.

[0044] An upper support plate 3 and a lower support plate 7 are fixedly installed on the inner wall of the storage cylinder 1. The lower support plate 7 is located below the upper support plate 3. Both the upper support plate 3 and the lower support plate 7 are connected to the inner wall of the storage cylinder 1 through support frames.

[0045] The outer wall of the transmission shaft 6 is rotatably connected to the inner wall of the upper support plate 3, and the bottom of the transmission shaft 6 is rotatably connected to the upper end surface of the lower support plate 7. Through the cooperation of the upper support plate 3 and the lower support plate 7, support is provided for the transmission shaft 6. The outer wall of the transfer box 9 is fixedly connected to the outer wall of the upper support plate 3, and the upper support plate 3 provides an installation position for the transfer box 9.

[0046] As a preferred embodiment of the present invention, a transmission ratchet wheel 20 is fixedly installed at one end of the mounting cylinder 10 away from the discharge plate 2. A control ratchet lever 19 for engaging with the transmission ratchet wheel 20 is elastically installed on the radial outer wall of the mounting shaft 13. A vertical rod is arranged on the outer wall of the mounting shaft 13, and the control ratchet lever 19 is connected to the vertical rod through a torsion spring. By engaging the control ratchet lever 19 and the transmission ratchet wheel 20, the mounting cylinder 10 is locked unidirectionally along the direction of its own axis rotation.

[0047] A transmission gear 17 is fixedly installed on the radially outer wall of the installation cylinder 10, and a sector gear ring 12 that cooperates with the transmission gear 17 is fixedly installed on the upper end surface of the lower support disk 7. During the rotation of the transmission shaft 6 along its own axis, the installation cylinder 10 rotates along the axis of the transmission shaft 6 until the transmission gear 17 and the sector gear ring 12 come into contact. At this time, the rotation of the installation cylinder 10 along its own axis is controlled through the cooperation of the transmission gear 17 and the sector gear ring 12, so that after cleaning the discharge plate 2, the installation cylinder 10 is rotated until the discharge plate 2 is in the vertical state again, facilitating the scraping of the foam material inside the storage cylinder 1 again.

[0048] A control lever 14 is fixedly installed on the outer wall of the upper support disk 3. When the installation cylinder 10 rotates along the axis of the transmission shaft 6, the control lever 14 is located within the rotation trajectory of the control ratchet lever 19. When the transmission shaft 6 rotates, the installation shaft 13 and the installation cylinder 10 rotate synchronously along the axis of the transmission shaft 6 until the control ratchet lever 19 passes over the control lever 14. At this time, one end of the control ratchet lever 19 is pressed by the control lever 14, causing the end of the control ratchet lever 19 in contact with the transmission ratchet wheel 20 to lift. At this time, the discharge plate 2 is rotated to the horizontal state through the control of the torsion spring.

[0049] Specifically, during operation, when the discharge plate 2 passes over the discharge port, the control ratchet lever 19 gradually approaches the control lever 14 until the control lever 14 lifts one end of the control ratchet lever 19. At this time, the torsion spring between the installation cylinder 10 and the installation shaft 13 controls the installation cylinder 10 and the discharge plate 2 to rotate along the axis of the installation cylinder 10. After the control lever 14 and the control ratchet lever 19 are separated again, the control ratchet lever 19 is engaged with the transmission ratchet wheel 20 again until the discharge plate 2 rotates from the vertical state to the horizontal state (the side of the discharge plate 2 that pushes the foam faces upward).

[0050] As the transmission shaft 6 continues to rotate, it drives the horizontally positioned discharge plate 2 to move below the cleaning brush 11 until the cleaning brush 11 wipes the discharge plate 2. After wiping, as the transmission shaft 6 rotates, at this time the transmission gear 17 comes into contact with the sector gear ring 12, causing the installation cylinder 10 to rotate in the reverse direction until the installation cylinder 10 rotates to the vertical state. At this time, through the cooperation of the control ratchet lever 19 and the transmission ratchet wheel 20, the installation cylinder 10 is locked unidirectionally, so that the discharge plate 2 remains in the vertical state. As the transmission shaft 6 rotates, it drives the discharge plate 2 to scrape the foam material.

[0051] As a preferred embodiment of the present invention, one end of the installation shaft 13 extends into the inner cavity of the installation cylinder 10 and is fixedly installed with a transmission plate 18. The outer wall of the transmission plate 18 is slidably fitted with the inner wall of the installation cylinder 10. During the rotation of the installation cylinder 10 along its own axis, the outer wall of the transmission plate 18 remains in a sealed and fitted state with the inner wall of the installation cylinder 10 (such as being connected through a sealed bearing).

[0052] A partition plate 15 is fixedly installed on the inner wall of the installation cylinder 10. The other end of the partition plate 15 is slidably attached to the outer wall of the installation shaft 13. The partition plate 15 divides the inner cavity of the installation cylinder 10 into two chambers.

[0053] A movable plate 16 is fixedly installed on the outer wall of the transmission plate 18. Through holes for damping liquid to pass through are formed on the outer wall of the movable plate 16. The chamber where the transmission plate 18 and the movable plate 16 are located is filled with damping liquid. During the rotation of the installation cylinder 10 along its own axis, the damping liquid is pushed by the transmission plate 18 and passes through the through holes on the outer wall of the movable plate 16 to generate damping. When the control ratchet lever 19 and the transmission ratchet wheel 20 are separated, the installation cylinder 10 is kept rotating at a uniform speed as much as possible to prevent the installation cylinder 10 from rotating at a high speed along its own axis, resulting in material splashing.

[0054] A cavity is provided inside the adapter box 9, and an exhaust port 25 is formed at the bottom of the adapter box 9. A flow guide plate 24 is fixedly installed on the bottom surface of the adapter box 9. The flow guide plate 24 is an elastic copper plate.

[0055] The exhaust port 25 is inclined towards the flow guide plate 24, and the flow guide plate 24 is bent towards the cleaning brush 11. When the discharge plate 2 passes through the cleaning brush 11, air is injected into the interior of the adapter box 9. The air is discharged through the exhaust port 25 and then blown towards the cleaning brush 11 through the flow guide plate 24, thereby controlling the cleaning brush 11 to shake and improving the efficiency of cleaning the discharge plate 2.

[0056] As a preferred embodiment of the present invention, a limit frame 23 is fixedly installed on the bottom surface of the installation frame 4, and a control cylinder 8 is fixedly installed inside the limit frame 23. The limit frame 23 provides installation and support for the control cylinder 8.

[0057] An air inlet pipe 22 and an exhaust pipe 21 are fixedly installed on the outer wall of the control cylinder 8. The air inlet pipe 22 is used for exhausting air into the control cylinder 8, and the exhaust pipe 21 is used for exhausting air from the control cylinder 8 to the outside. Among them, one-way valves are provided inside both the air inlet pipe 22 and the exhaust pipe 21.

[0058] The other end of the exhaust pipe 21 is communicated with the inner cavity of the adapter box 9. By adjusting the air pressure inside the control cylinder 8, the air inside the adapter box 9 is controlled to be discharged through the exhaust port 25.

[0059] A control plug 31 is slidably installed inside the control cylinder 8. The outer wall of the control plug 31 is hermetically attached to the inner wall of the control cylinder 8. By reciprocally sliding the control plug 31, external air is controlled to enter the inner cavity of the control cylinder 8 through the air inlet pipe 22 and then be discharged to the inner cavity of the adapter box 9 through the exhaust pipe 21.

[0060] A blocking frame 29 is fixedly installed on the inner wall of the control cylinder 8. The side wall of the blocking frame 29 is elastically connected to the outer wall of the control plug 31. A spring is arranged on the outer wall of the blocking frame 29, and the other end of the spring is fixedly connected to the outer wall of the control plug 31. After sliding the control plug 31, the control plug 31 is driven to reset by the elastic force of the spring.

[0061] A guide rod 30 is fixedly installed on the outer wall of the control plug 31. The guide rod 30 penetrates through the blocking frame 29 and is slidably connected to the blocking frame 29. By arranging the guide rod 30, the sliding stability of the control plug 31 is improved.

[0062] A transmission cam 26 is fixedly installed on the outer wall of the output shaft of the driving motor 5. When the driving motor 5 controls the transmission shaft 6 to rotate, the transmission cam 26 is synchronously driven to rotate.

[0063] A transmission rod 28 is fixedly installed on the outer wall of the control plug 31. The transmission rod 28 penetrates through the blocking frame 29, and the outer wall of the transmission rod 28 is slidably attached to the inner wall of the blocking frame 29. Sliding the transmission rod 28 drives the control plug 31 to slide synchronously, thereby adjusting the air pressure inside the control cylinder 8.

[0064] The other end of the transmission rod 28 is fixedly installed with a top pressure plate 27. The outer wall of the top pressure plate 27 is slidably attached to the radial outer wall of the transmission cam 26. During the rotation of the transmission cam 26, the top pressure plate 27 is pushed, thereby pushing the control plug 31 to slide. Cooperating with the elastic force of the spring, the control plug 31 is driven to slide reciprocally, so as to exhaust air from the exhaust port 25 at the bottom of the transfer box 9.

Taking the perspective of the observer as the standard, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
