Description

Technical Field

[0001] The invention belongs to the technical field of flotation machines, in particular to a flotation machine for ore dressing. Background Art

[0002] Flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the slurry treated with reagents is stirred and aerated so that some of the mineral particles are selectively fixed on the bubbles, float to the surface of the slurry and are scraped out to form foam products, while the rest are retained in the slurry to achieve the purpose of separating minerals.

[0003] The patent with announcement number CN219073238U discloses a flotation machine scraper cleaning device, which relates to the technical field of flotation machines, including: a flotation machine housing, with brackets on the left and right sides of the front top, respectively, and a scraper hollow shaft rotatably connected between the two brackets; a flotation machine scraper unit, including a fixed sleeve, a fixing screw, a connecting assembly and a scraper, the scraper hollow shaft is located between the two brackets and is sleeved with four fixed sleeves at equal distances, the threaded holes on the fixed sleeves are threadedly connected to the fixing screws, the fixing screws are against the outside of the scraper hollow shaft, the upper and lower ends of the two fixed sleeves on the left are respectively connected to the scraper through the connecting assembly, and the upper and lower ends of the two fixed sleeves on the right are also respectively connected to the scraper through the connecting assembly. This technology can scrape and clean after a large amount of slurry is condensed on the scraper, avoiding increasing the transmission energy consumption of the flotation machine and reducing the excessive wear of the scraper bearing.

[0004] Although the above technology can clean the scraper, since the U-shaped scraper bar is sleeved on the outer wall of the scraper, when the scraper scrapes off the flotation foam, the U-shaped scraper bar moves synchronously with the scraper. During the flotation process, the U-shaped scraper bar is slid to scrape off the attachments on the outer wall of the scraper. The movement of one of the U-shaped scrapers located in the flotation machine housing will destroy the foam, affecting the flotation efficiency. If the scraper is cleaned after the flotation operation is completed, the foam and mineral impurities accumulated on the scraper will reduce the contact surface and scraping effect of the scraper, resulting in the accumulation of foam in the tank, thus affecting the flotation efficiency.

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 flotation machine for mineral processing of the present invention comprises a flotation mechanism, a driving mechanism, a transmission mechanism, a scraping mechanism, a cleaning mechanism and a knocking mechanism.

[0021] The flotation mechanism includes a flotation box 1, a collection trough 4 and a flotation plate 7. The collection trough 4 is fixedly installed on the outer wall of the flotation box 1. The flotation plate 7 rotates to push the flotation material in the flotation box 1 into the inner cavity of the collection trough 4. During the flotation process, the mineral particles adhere to the bubbles and float to the flotation liquid surface through the combination of bubbles and mineral particles in the flotation box 1. The flotation plate 7 is responsible for scraping the foam containing the target mineral from the liquid surface and guiding it into the foam collection trough 4.

[0022] The scraping mechanism includes a mounting frame 3, a load-bearing shaft 12 and a scraping plate 17. The mounting frame 3 is fixedly mounted on the outer wall of the collecting trough 4. The load-bearing shaft 12 is rotatably mounted on the side wall of the mounting frame 3 through an elastic member. A torsion spring is provided on the outer wall of the load-bearing shaft 12. The other end of the torsion spring is fixedly connected to the outer wall of the mounting frame 3. After the load-bearing shaft 12 is rotated, the elastic force of the torsion spring is used to control the load-bearing shaft 12 to rotate and reset.

[0023] The scraper plate 17 is located within the rotation track of the flotation plate 7 and is elastically connected to the bearing shaft 12. After the scraper plate 17 is separated from the liquid surface in the flotation box 1, the bearing shaft 12 is rotated until the scraper plate 17 is in contact with the flotation plate 7. At this time, the flotation plate 7 is continued to be rotated so that the scraper plate 17 slides along the outer wall of the flotation plate 7, thereby scraping off the material attached to the outer wall of the flotation plate 7 and dripping it into the collecting trough 4. Compared with the method of scraping the attachments on the outer wall of the flotation plate 7 inside the flotation box 1, the degree of destruction of the flotation material foam in the flotation box can be reduced. In addition, by scraping off the attachments on the outer wall of the flotation plate 7, the accumulation of foam and mineral impurities can be prevented, thereby maintaining the flotation efficiency.

[0024] The cleaning mechanism includes a mounting beam 16 and an exhaust pipe 14, wherein the mounting beam 16 is fixedly mounted on the upper end of the mounting frame 3, and the exhaust pipe 14 is fixedly mounted on the outer wall of the mounting beam 16, wherein the mounting beam 16 provides installation and support for the exhaust pipe 14, and multiple exhaust pipes 14 are evenly arranged along the outer wall of the mounting beam 16, and the multiple exhaust pipes 14 exhaust downward.

[0025] After the scraper plate 17 and the flotation plate 7 are separated, the bearing shaft 12 is rotated so that the scraper plate 17 is in a vertical state (located below the mounting beam 16), and at this time the scraper plate 17 is away from the movement trajectory of the flotation plate 7. At this time, air is blown downward through the exhaust pipe 14, thereby increasing the rate at which the material scraped by the outer wall of the scraper plate 17 flows into the collecting trough 4, thereby cleaning the scraper plate 17 so as to facilitate scraping the flotation plate 7 again.

[0026] The driving mechanism is used to control the rotation of the flotation plate 7, and the driving mechanism controls the intermittent rotation of the bearing shaft 12 through the transmission mechanism. In order to increase the flotation rate, multiple flotation plates 7 are provided. Controlling the intermittent rotation of the bearing shaft 12 can facilitate the scraping plate 17 to scrape the outer walls of different flotation plates 7.

[0027] The knocking mechanism is used to knock the scraper plate 17 when the scraper plate 17 is close to the mounting beam 16, and knocking the scraper plate 17 further increases the flow speed of the surface attachment when the scraper plate 17 is vertical.

[0028] The driving mechanism includes a driving motor 2, a support frame 5 and a transmission shaft 6. The transmission shaft 6 is rotatably arranged at the upper end of the flotation box 1, and the support frame 5 is fixedly installed on the outer wall of the transmission shaft 6. Rotating the transmission shaft 6 drives the support frame 5 to rotate.

[0029] The side wall of the flotation plate 7 is rotationally connected to the outer wall of the support frame 5 via a torsion spring, wherein a plurality of flotation plates 7 are mounted on the outer wall of the support frame 5 , and when the transmission shaft 6 rotates, the plurality of flotation plates 7 rotate along the axis of the transmission shaft 6 .

[0030] The driving motor 2 is fixedly mounted on the outer wall of the flotation box 1 and is used to control the rotation of the transmission shaft 6 . The driving motor 2 is connected to the transmission shaft 6 through the cooperation of a belt and a pulley, so that the rotation of the transmission shaft 6 is controlled by the driving motor 2 .

[0031] As a preferred embodiment of the present invention, the transmission mechanism includes a transmission gear 8 , a sector gear 10 and a connecting shaft 9 . The connecting shaft 9 is rotatably mounted on the outer wall of the mounting frame 3 , and the mounting frame 3 provides support for the connecting shaft 9 .

[0032] The sector gear 10 is fixedly mounted on the outer wall of the connecting shaft 9, one end of the transmission gear 8 is fixedly connected to the axial end of the load-bearing shaft 12, and the transmission gear 8 is meshed with the sector gear 10. Rotating the sector gear 10 drives the transmission gear 8 and the load-bearing shaft 12 to rotate intermittently.

[0033] When the sector gear 10 and the transmission gear 8 are in a meshing state, rotating the sector gear 10 drives the transmission gear 8 to rotate. At this time, the load-bearing shaft 12 rotates until the scraper plate 17 fits against the flotation plate 7. After the scraper plate 17 scrapes the outer wall of the flotation plate 7, the sector gear 10 separates from the transmission gear 8. At this time, the elastic force of the torsion spring controls the load-bearing shaft 12 to rotate in the opposite direction, so that the scraper plate 17 is lifted to the bottom of the mounting beam 16.

[0034] The connecting shaft 9 rotates synchronously with the transmission shaft 6 , and the connecting shaft 9 and the transmission shaft 6 are connected by a belt and a pulley, so as to maintain the synchronization of the rotation of the flotation plate 7 and the scraper plate 17 .

[0035] An elastic sheet 15 is fixedly installed on the outer wall of the load-bearing shaft 12, and the other end of the elastic sheet 15 is fixedly connected to the outer wall of the scraper plate 17. The elastic connection between the load-bearing shaft 12 and the scraper plate 17 is realized by setting the elastic sheet 15, and when the scraper plate 17 scrapes the outer wall of the flotation plate 7, the scraper plate 17 is prevented from interfering with the movement of the flotation plate 7.

[0036] A scraping groove 19 is provided on one side of the scraping plate 17 close to the flotation plate 7 . The inner wall of the scraping groove 19 is inclined to improve the efficiency of the scraping plate 17 scraping the outer wall of the flotation plate 7 .

[0037] The flotation plate 7 is made of magnetic material, and a magnetic block 18 is fixedly installed on the side of the elastic sheet 15 away from the scraper plate 17. In this embodiment, the flotation plate 7 is made of common martensitic stainless steel that can be attracted by a magnet. When the flotation plate 7 is close to the scraper plate 17, the magnetic force of the magnetic block 18 attracts the flotation plate 7 to deflect, so that the scraper plate 17 and the flotation plate 7 can fit together, thereby improving the scraping efficiency and maintaining the flotation efficiency.

[0038] As a preferred embodiment of the present invention, a control cylinder 11 is fixedly installed on the outer wall of the mounting frame 3. The control cylinder 11 has an air inlet nozzle and an exhaust nozzle, and the exhaust nozzle of the control cylinder 11 is connected to the exhaust pipe 14 through a conduit. The exhaust of the exhaust pipe 14 is controlled by adjusting the air pressure inside the control cylinder 11, wherein a one-way valve is provided in both the exhaust nozzle and the air inlet nozzle.

[0039] One end of the connecting shaft 9 extends to the inner cavity of the control cylinder 11 and is fixedly mounted with a reciprocating screw 25 . The connecting shaft 9 drives the reciprocating screw 25 to rotate synchronously during its rotation.

[0040] A control plug 26 is slidably mounted on the inner wall of the control cylinder 11. The control plug 26 slides back and forth to push the air in the control cylinder 11 into the exhaust pipe 14 and is discharged from the exhaust pipe 14, so as to blow air toward the outer wall of the scraper plate 17 when the scraper plate 17 is vertical.

[0041] The reciprocating screw 25 penetrates the control plug 26 and is connected to the reciprocating screw 25 by means of internal and external threads. The reciprocating screw 25 is rotated to drive the control plug 26 to slide back and forth, thereby controlling the exhaust of the exhaust pipe 14 (the gas in the control tube 11 is partially discharged from the exhaust pipe 14 to control the blowing of the exhaust pipe 14, so there is no need for absolute sealing between the control plug 26 and the reciprocating screw 25).

[0042] As a preferred embodiment of the present invention, the tapping mechanism includes a mounting rod 24, a mounting bar 22 and a tapping hammer 33. The mounting rod 24 is fixedly mounted on the outer wall of the mounting frame 3, and the mounting bar 22 is connected to the mounting rod 24 through a torsion spring. After the mounting bar 22 is rotated, the mounting bar 22 is controlled to reset by the elastic force of the torsion spring.

[0043] The mounting bar 22 is rotatably mounted on the outer wall of the mounting rod 24 via a torsion spring, and the knocking hammer 33 is fixedly mounted on the outer wall of the mounting bar 22. When the scraper plate 17 approaches the mounting beam 16, the mounting bar 22 is moved to control the knocking hammer 33 to swing back and forth, thereby achieving the knocking of the scraper plate 17.

[0044] A transmission rod 23 is rotatably provided at one end of the control cylinder 11 away from the mounting frame 3 , and a transmission collar 21 is fixedly installed on the radial outer wall of the transmission rod 23 . Rotating the transmission rod 23 drives the transmission collar 21 to rotate synchronously.

[0045] A transmission plate 32 is fixedly installed on the outer wall of the transmission ring 21. The mounting strip 22 and the transmission plate 32 are both made of elastic material, and the end of the mounting strip 22 away from the knock hammer 33 extends into the rotation track of the mounting strip 22. The rotating transmission rod 23 drives the transmission ring 21 and the transmission plate 32 to rotate, and the mounting strip 22 is deflected by the transmission plate 32 until the transmission plate 32 is separated from the mounting strip 22, which is used to control the knock hammer 33 to knock on the outer wall of the scraper plate 17.

[0046] A support cylinder 20 is fixedly mounted on one axial end of the control cylinder 11 , and a transmission rod 23 is rotatably connected to the support cylinder 20 , so that the support cylinder 20 provides support for the transmission rod 23 .

[0047] A transmission disc 28 is rotatably mounted on the inner wall of the support tube 20 . The transmission disc 28 is fixedly connected to the axial end of the reciprocating screw 25 . When the reciprocating screw 25 rotates, the transmission disc 28 rotates synchronously.

[0048] A connecting rod 31 is fixedly installed on the axial end of the transmission rod 23, and the connecting rod 31 is connected to the transmission disk 28 through an elastic member, wherein the connecting rod 31 is connected to the transmission disk 28 through a torsion spring. When the transmission disk 28 rotates, the elastic force of the torsion spring controls the rotation of the connecting rod 31 and the transmission rod 23, so as to drive the mounting bar 22 to deflect.

[0049] A limiting ratchet 27 is fixedly installed on the radial outer wall of the transmission rod 23, and a limiting ratchet rod 30 engaged with the limiting ratchet 27 is elastically installed on the inner wall of the support tube 20. The limiting ratchet rod 30 and the limiting ratchet 27 are engaged to achieve one-way locking of the rotation of the transmission rod 23. When the transmission rod 23 needs to be rotated, the limiting ratchet rod 30 is rotated until the limiting ratchet rod 30 is separated from the limiting ratchet 27.

[0050] A control sheet 29 is fixedly mounted on the outer wall of the limiting ratchet rod 30 , and an attraction block 13 for attracting the control sheet 29 is fixedly mounted on the outer wall of the bearing shaft 12 . The control sheet 29 and the attraction block 13 are two magnets that attract each other.

[0051] When the scraper plate 17 scrapes the flotation plate 7, the limit ratchet rod 30 and the limit ratchet wheel 27 are engaged, and the transmission plate 28 rotates. The torsion spring between the transmission plate 28 and the connecting rod 31 stores elastic potential energy. In the process of the bearing shaft 12 rotating to control the scraper plate 17 to approach the mounting beam 16, the attraction block 13 gradually approaches the control plate 29 and then attracts the limit ratchet rod 30 and the limit ratchet wheel 27 to separate. At this time, the transmission rod 23 is controlled to rotate by the elastic force of the torsion spring, and the mounting bar 22 is deflected by the transmission plate 32. In the process of the scraper plate 17 moving away from the mounting beam 16, the attraction block 13 gradually moves away from the control plate 29. At this time, the limit ratchet rod 30 is again engaged with the limit ratchet wheel 27 by the elastic force to facilitate the next operation.

Figure 1 As a benchmark, according to the person's observation perspective, 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.
