[0004] Although the above technology can improve the overall work efficiency, various mineral particles, flotation agent residues and impurities in the slurry are very easy to adhere to the surface of the driving blade. These attachments accumulate over time, causing the surface roughness of the driving blade to increase continuously, and the originally smooth scraping surface becomes uneven. As a result, during the scraping process, the effective contact area between the driving blade and the foam layer is reduced, and the scraping efficiency is greatly reduced, resulting in a large amount of foam containing useful minerals unable to be scraped out of the flotation tank in time, seriously affecting the flotation recovery rate.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] like Figures 1 to 8 As shown, the circular flotation machine for efficient sorting described in the present invention comprises a flotation machine body, a driving mechanism, a control mechanism and a cleaning mechanism.

[0021] The flotation machine body includes a storage cylinder 1 and a discharge plate 2. The interior of the storage cylinder 1 provides a storage 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 air is injected 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 to realize the flotation operation of the mineral.

[0022] The driving mechanism comprises a mounting frame 4, a driving motor 5 and a transmission shaft 6. The mounting frame 4 is fixedly mounted on the upper end surface of the storage cylinder 1. The upper end of the storage cylinder 1 is provided with an opening, and the mounting frame 4 is located above the opening.

[0023] The drive motor 5 is fixedly mounted on the upper end surface of the mounting frame 4, and the output shaft of the drive motor 5 is connected to the transmission shaft 6. The drive motor 5 is used to control the rotation of the transmission shaft 6. The rotation of the discharge plate 2 is controlled by the transmission shaft 6, wherein multiple discharge plates 2 are arranged in a ring shape along the axis of the transmission shaft 6.

[0024] The control mechanism includes a mounting shaft 13 and a mounting cylinder 10. The mounting shaft 13 is fixedly mounted on the radial outer wall of the transmission shaft 6. The axis of the mounting shaft 13 is perpendicular to the axis of the transmission shaft 6. The rotation of the transmission shaft 6 drives the mounting shaft 13 to rotate synchronously.

[0025] The mounting cylinder 10 is rotatably connected to the mounting shaft 13 through an elastic member, and 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 provided on the outer wall of the mounting shaft 13, and the other end of the torsion spring is connected to the inner wall of the mounting cylinder 10.

[0026] The elastic force of the torsion spring controls the mounting cylinder 10 so that the discharge plate 2 tends to be parallel to the liquid surface inside the storage cylinder 1 in real time.

[0027] The brush cleaning mechanism includes an adapter box 9 and a cleaning brush 11. The adapter box 9 is arranged in the storage tube 1, and the cleaning brush 11 is fixedly installed on the bottom surface of the adapter box 9. When the discharge plate 2 rotates to a horizontal state, the rotating transmission shaft 6 drives the discharge plate 2 to pass through the bottom of the cleaning brush 11, so that the cleaning brush 11 wipes the side of the discharge plate 2 that pushes the foam, thereby wiping the sticky material and dripping it into the interior of the storage tube 1, thereby cleaning the discharge plate 2, keeping the outer wall of the discharge plate 2 clean during the flotation process, and improving the quality of flotation.

[0028] An upper support plate 3 and a lower support plate 7 are fixedly mounted 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 via a support frame.

[0029] 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 adapter box 9 is fixedly connected to the outer wall of the upper support plate 3, and an installation position is provided for the adapter box 9 through the upper support plate 3.

[0030] As a preferred embodiment of the present invention, a transmission ratchet 20 is fixedly installed at one end of the mounting cylinder 10 away from the discharge plate 2, and a control ratchet rod 19 for engaging with the transmission ratchet 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 rod 19 is connected to the vertical rod through a torsion spring. By engaging the control ratchet rod 19 and the transmission ratchet 20, the mounting cylinder 10 is unidirectionally locked in the rotation direction along its own axis.

[0031] A transmission gear 17 is fixedly installed on the radial outer wall of the mounting cylinder 10, and a sector-shaped gear ring 12 cooperating with the transmission gear 17 is fixedly installed on the upper end surface of the lower support plate 7. When the transmission shaft 6 rotates along its own axis, the mounting cylinder 10 rotates along the axis of the transmission shaft 6 until the transmission gear 17 and the sector-shaped gear ring 12 contact. At this time, the mounting cylinder 10 is controlled to rotate synchronously along its own axis through the cooperation of the transmission gear 17 and the sector-shaped gear ring 12. After cleaning the discharge plate 2, the mounting cylinder 10 is rotated until the discharge plate 2 is in a vertical state again, so as to facilitate scraping the foam material inside the storage cylinder 1 again.

[0032] A control lever 14 is fixedly installed on the outer wall of the upper support plate 3. When the mounting 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 rod 19. When the transmission shaft 6 rotates, the mounting shaft 13 and the mounting cylinder 10 rotate synchronously along the axis of the transmission shaft 6 until the control ratchet rod 19 passes over the control lever 14. The control lever 14 presses one end of the control ratchet rod 19, so that the end of the control ratchet rod 19 that contacts the transmission ratchet 20 is lifted. At this time, the discharge plate 2 is rotated to a horizontal state through the torsion spring.

[0033] Specifically, during operation, after the discharge plate 2 passes over the discharge port, the control ratchet rod 19 gradually approaches the control lever 14 until the control lever 14 lifts one end of the control ratchet rod 19. At this time, the torsion spring between the mounting cylinder 10 and the mounting shaft 13 controls the mounting cylinder 10 and the discharge plate 2 to rotate along the axis of the mounting cylinder 10. After the control lever 14 and the control ratchet rod 19 are separated again, the control ratchet rod 19 is engaged with the transmission ratchet 20 again until the discharge plate 2 rotates from a vertical state to a horizontal state (the discharge plate 2 pushes one side of the foam upward).

[0034] As the transmission shaft 6 continues to rotate, the horizontal discharge plate 2 is driven to move under the cleaning brush 11 until the cleaning brush 11 wipes the discharge plate 2. After wiping, as the transmission shaft 6 rotates, the transmission gear 17 contacts the fan-shaped gear ring 12, causing the mounting cylinder 10 to rotate in the opposite direction until the mounting cylinder 10 rotates to a vertical state. At this time, the mounting cylinder 10 is locked in one direction by controlling the ratchet rod 19 and the transmission ratchet wheel 20 to keep the discharge plate 2 in a vertical state. As the transmission shaft 6 rotates, the discharge plate 2 is driven to scrape the foam material.

[0035] As a preferred embodiment of the present invention, one end of the mounting shaft 13 extends to the inner cavity of the mounting cylinder 10, and a transmission plate 18 is fixedly installed thereon, and the outer wall of the transmission plate 18 is slidably fitted with the inner wall of the mounting cylinder 10. During the rotation of the mounting cylinder 10 along its own axis, the outer wall of the transmission plate 18 and the inner wall of the mounting cylinder 10 maintain a sealed fit state (such as being connected by a sealed bearing).

[0036] A partition plate 15 is fixedly mounted on the inner wall of the installation tube 10 , and the other end of the partition plate 15 is slidably fitted with the outer wall of the installation shaft 13 . The partition plate 15 divides the inner cavity of the installation tube 10 into two chambers.

[0037] The outer wall of the transmission plate 18 is fixedly mounted with a movable plate 16, and the outer wall of the movable plate 16 is provided with a through hole for the damping fluid to pass through. The chamber where the transmission plate 18 and the movable plate 16 are located is filled with damping fluid. In the process of the mounting cylinder 10 rotating along its own axis, the damping fluid is pushed by the transmission plate 18 to move and pass through the through hole on the outer wall of the movable plate 16 to generate damping. When the control ratchet rod 19 and the transmission ratchet wheel 20 are separated, the mounting cylinder 10 is kept rotating at a uniform speed as much as possible to prevent the mounting cylinder 10 from rotating at a high speed along its own axis and causing material splashing.

[0038] The adapter box 9 has a cavity inside and an exhaust port 25 at the bottom. A guide plate 24 is fixedly mounted on the bottom of the adapter box 9. The guide plate 24 is an elastic copper plate.

[0039] The exhaust port 25 is inclined toward the guide plate 24, and the guide plate 24 is bent toward the cleaning brush 11. When the discharge plate 2 passes the cleaning brush 11, air is injected into the interior of the adapter box 9, and the air is discharged through the exhaust port 25, and then blown toward the cleaning brush 11 through the guide plate 24, thereby controlling the shaking of the cleaning brush 11 and improving the efficiency of cleaning the discharge plate 2.

[0040] As a preferred embodiment of the present invention, a limit frame 23 is fixedly installed on the bottom surface of the mounting frame 4 , and a control cylinder 8 is fixedly installed inside the limit frame 23 , so that the limit frame 23 provides installation and support for the control cylinder 8 .

[0041] An intake pipe 22 and an exhaust pipe 21 are fixedly mounted on the outer wall of the control tube 8. The intake pipe 22 is used to exhaust air into the control tube 8, and the exhaust pipe 21 is used to exhaust air from the control tube 8 to the outside. Both the intake pipe 22 and the exhaust pipe 21 are provided with a one-way valve.

[0042] The other end of the exhaust pipe 21 is communicated with the inner cavity of the transfer box 9 , and the air pressure inside the transfer box 9 is adjusted by adjusting the control cylinder 8 , so that the air inside the transfer box 9 is controlled to be discharged from the exhaust port 25 .

[0043] A control plug 31 is slidably installed in the inner cavity of the control cylinder 8, and the outer wall of the control plug 31 is sealed and fitted with the inner wall of the control cylinder 8. The reciprocating sliding control plug 31 controls the external air to enter the inner cavity of the control cylinder 8 through the intake pipe 22, and then be discharged to the inner cavity of the adapter box 9 through the exhaust pipe 21.

[0044] A blocking frame 29 is fixedly installed on the inner wall of the control cylinder 8, and the side wall of the blocking frame 29 is elastically connected to the outer wall of the control plug 31. A spring is provided 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 the control plug 31 is slid, the elastic force of the spring drives the control plug 31 to reset.

[0045] A guide rod 30 is fixedly mounted on the outer wall of the control plug 31 . The guide rod 30 passes through the blocking frame 29 and is slidably connected to the blocking frame 29 . The guide rod 30 is provided to improve the sliding stability of the control plug 31 .

[0046] A transmission cam 26 is fixedly mounted 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.

[0047] A transmission rod 28 is fixedly mounted on the outer wall of the control plug 31 . The transmission rod 28 passes through the blocking frame 29 , and the outer wall of the transmission rod 28 slides in contact with the inner wall of the blocking frame 29 . The sliding transmission rod 28 drives the control plug 31 to slide synchronously, thereby adjusting the air pressure inside the control cylinder 8 .

[0048] A pressure plate 27 is fixedly installed on the other end of the transmission rod 28. The outer wall of the pressure plate 27 slides with the radial outer wall of the transmission cam 26. During the rotation of the transmission cam 26, the 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 back and forth to facilitate the exhaust of the exhaust port 25 at the bottom of the adapter box 9.
