Description

Technical Field

[0001] The invention relates to the technical field of flotation machines, in particular to a copper ore defoaming flotation machine. Background Art

[0002] Flotation machines are suitable for the separation of non-ferrous and ferrous metals, and can also be used for the separation of non-metals such as coal fluorite and talc. The flotation machine is driven by an electric motor to rotate the impeller, which generates a centrifugal effect to form a negative pressure. On the one hand, it draws in sufficient air to mix with the slurry, and on the other hand, it stirs the slurry and mixes the drugs, while refining the foam so that the minerals adhere to the foam and float to the surface of the slurry to form mineralized foam. Flotation machines are mainly used to separate non-ferrous metals such as copper, zinc, lead, nickel, and gold. They can also be used for the roughing and concentrating of ferrous metals and non-metals.

[0003] The copper ore defoaming flotation machine uses a reciprocating pushing mechanism to push the foam layer on the liquid surface, so that the foam layer is pushed away from the liquid surface. However, due to the viscosity between the foam and the reciprocating pushing mechanism, during the resetting process of the pushing mechanism, some foam fails to separate from the pushing mechanism in time and moves back to the liquid surface with the pushing mechanism. During this period, some foam on the pushing mechanism breaks and the minerals fall back into the slurry, which limits the efficiency of the copper ore defoaming flotation machine in pushing away the foam, thereby reducing the flotation efficiency of the copper ore defoaming flotation machine.

[0025] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0026] Example 1, see Figures 1 to 6 As shown, a copper ore defoaming flotation machine includes a base frame 1 and further includes:

[0027] An air flotation stirring mechanism 2 fixedly connected to the base frame 1, wherein the air flotation stirring mechanism 2 foams the copper ore slurry by stirring the copper ore slurry;

[0028] The bubble shifting mechanism 3 connected to the base frame 1 includes a support frame 4 fixedly connected to the base frame 1, the support frame 4 is fixedly connected to a double-output shaft motor 5, one output end of the double-output shaft motor 5 is connected to a pushing mechanism 6, the pushing mechanism 6 is movably connected to a pushing frame 7, the other output end of the double-output shaft motor 5 is connected to a brewing mechanism 9 through a belt transmission structure 8, when the double-output shaft motor 5 drives the pushing frame 7 through the pushing mechanism 6, the double-output shaft motor 5 drives the brewing mechanism 9 through the belt transmission structure 8, the brewing mechanism 9 includes a vertical frame 10 fixedly connected to the base frame 1, the vertical frame 10 is fixedly connected to a water storage tank 11, the water storage tank 11 is connected to a release structure 12, the release structure 12 is connected to the belt transmission structure 8, the water storage tank 11 is fixedly connected to a nozzle 13 facing the pushing frame 7 through a first water pipe, and the nozzle 13 is provided with multiple groups of water outlets;

[0029] A collecting box 14 is fixedly connected to the base frame 1 and has a collecting port.

[0030] The flotation stirring mechanism 2 aerates and stirs the copper ore slurry, so that the separately crushed bubbles contact with the ore particles to form mineralized bubbles, and the mineralized bubbles float up to form mineralized foam. Driven by the double-shaft motor 5, the push frame 7 moves and pushes the mineralized foam, so that the mineralized foam moves to the collection box 14. After the push frame 7 moves above the collection box 14, driven by the belt transmission structure 8, the release structure 12 releases the water stored in the water storage tank 11. The water stored in the water storage tank 11 enters the nozzle 13 through the first water pipe. The nozzle 13 sprays water on the push frame 7. On the one hand, the water sprayed by the nozzle 13 breaks through the mineralized foam. On the other hand, the water sprayed by the nozzle 13 forms a water flow on the surface of the push frame 7 and drives the mineralized foam to slide away from the push frame 7, thereby causing the mineralized foam to break away from the push frame 7 and fall into the collection box 14. The present invention drives the push frame 7 to push away the foam through the pushing mechanism 6, and after the push frame 7 moves to the collection box 14, the brewing mechanism 9 cleans the foam on the push frame 7, thereby preventing the mineralized foam on the push frame 7 from falling back into the copper ore slurry when the push frame 7 is reset, thereby improving the efficiency of pushing away the mineralized foam of the present invention.

[0031] In one case of this embodiment, the support frame 4 is fixedly connected to a dust cover 15, which is provided with an observation port and is connected to the belt transmission structure 8. The dust cover 15 is used to shield the belt transmission structure 8 from dust.

[0032] In one case of this embodiment, the air flotation stirring mechanism 2 includes an air flotation tank 16 fixedly connected to the base frame 1, and a foam port 17 is opened on the side of the air flotation tank 16 away from the base frame 1, and the foam port 17 is used to provide space for the floating of the foam. The air flotation tank 16 is fixedly connected to a shell 18, and the shell 18 is fixedly connected to an air guide pipe 19, and the air guide pipe 19 is used to connect an external pressurizing device. The shell 18 is fixedly connected to a first motor 20, and the first motor 20 can be optionally a servo motor or a stepping motor. The output shaft of the first motor 20 is fixedly connected to a hollow tube 22 through a bridge frame 21. The core tube 22 is rotatably connected to the inner wall of the shell 18. The hollow tube 22 is fixedly connected to a fall-prevention disc rotatably connected to the shell 18 to prevent the hollow tube 22 from falling. The hollow tube 22 is fixedly connected to a stirring impeller 24 via a mesh cover 23. Pressurized gas enters the hollow tube 22 through an air duct 19, and then the air is sprayed from the mesh cover 23 into the ore slurry, forming bubbles. The stirring impeller 24 includes a disc fixedly connected to the mesh cover 23, which is fixedly connected to stirring blades arranged along a circumferential direction. The shell 18 is fixedly connected to a liquid guide pipe 25, which is used to connect to an external liquid supply device. A first motor 20 drives the hollow tube 22 to rotate via a bridge 21, causing the hollow tube 22 to rotate the mesh cover 23, and the stirring impeller 24 rotates with the mesh cover 23. The stirring impeller 24 stirs and mixes the bubbles that float out of the mesh cover 23 with the copper ore slurry, thereby facilitating the formation of mineralized bubbles.

[0033] In one case of this embodiment, the pushing mechanism 6 includes a connecting frame 26 fixedly connected to the output shaft of the dual-output shaft motor 5, the connecting frame 26 is fixedly connected to the driving rod 27, the support frame 4 is fixedly connected to the limiting frame 44, the limiting frame 44 is slidably connected to the linkage frame 28, the linkage frame 28 is slidably connected to the support frame 4, the linkage frame 28 is fixedly connected to the guide frame 29, a straight groove 30 is provided on the guide frame 29, the straight groove 30 is connected to an arc groove 31 provided on the guide frame 29, the arc groove 31 is a circular arc structure, the curvature radius of the arc groove 31 is the same as the radius of the rotation path of the driving rod 27, the driving rod 27 is slidably connected to the straight groove 30, the linkage frame 28 is fixedly connected to a connecting arm 32, and the connecting arm 32 is connected to the pushing frame 7. The double-output shaft motor 5 drives the connecting frame 26 to rotate, and the connecting frame 26 drives the driving rod 27 to move, so that the driving rod 27 slides in the straight groove 30. At the same time, the guide frame 29 drives the linkage frame 28 to move, and the linkage frame 28 slides relative to the limit frame 44, and the linkage frame 28 drives the pushing frame 7 to move through the connecting arm 32, so that the pushing frame 7 pushes the mineralized foam to move toward the collection box 14. When the driving rod 27 slides in the arc groove 31, the guide frame 29, the linkage frame 28, and the connecting arm 32 all stop, and the brewing mechanism 9 cleans the pushing frame 7 with foam. Then, as the driving rod 27 moves to the end of the arc groove 31, the driving rod 27 pushes the guide frame 29, and the guide frame 29 slides with the limit frame 44. The guide frame 29 drives the linkage frame 28 to rotate, lift and reset, so that the linkage frame 28 drives the pushing frame 7 to reset through the connecting arm 32. At this time, the pushing frame 7 is lifted, so that the amount of mineralized foam in contact with the pushing frame 7 is reduced during the reset process of the pushing frame 7.

[0034] In one aspect of this embodiment, the push frame 7 includes a sleeve 33 movably connected to the connecting arm 32. The sleeve 33 is fixedly connected to a bubble pushing plate 43 for pushing the mineralized foam. The bubble pushing plate 43 is fixedly connected to an L-shaped frame 34, which is fixedly connected to a gripping handle. The L-shaped frame 34 is threadedly connected to a locking bolt, the end of which abuts the connecting arm 32. By providing the locking bolt abutting the connecting arm 32, the friction between the locking bolt and the connecting arm 32 is increased, thereby restricting the movement of the sleeve 33 and the bubble pushing plate 43.

[0035] In one aspect of this embodiment, the release mechanism 12 includes a cam 35 coaxially connected to the output end of the belt drive mechanism 8. A lifting plug 36 is slidably mounted within the water storage tank 11. A spring is installed between the lifting plug 36 and the water storage tank 11, providing a pulling force to reset the lifting plug 36. The lifting plug 36 is fixedly connected to an extension frame 37, which is slidably connected to the water storage tank 11. A slide rod 38 is fixedly connected to the extension frame 37, which is slidably connected to the cam 35. The belt drive mechanism 8 drives the cam 35 to rotate, which pushes the slide rod 38. The slide rod 38, via the extension frame 37, drives the lifting plug 36 away from the bottom of the water storage tank 11, thereby allowing water in the water storage tank 11 to flow into the showerhead 13 through the first water pipe. As the cam 35 rotates and the spring pulls the lifting plug 36, the lifting plug 36 resets, preventing water in the water storage tank 11 from flowing into the first water pipe.

[0036] Example 2, based on Example 1, refer to Figure 2 The belt drive structure 8 includes a driving pulley 39 fixedly connected to one output end of the dual-shaft motor 5. The driving pulley 39 is connected to a driven pulley 41 via a toothed belt 40. Both the driving pulley 39 and the driven pulley 41 are meshed with the toothed belt 40. The driven pulley 39 and the driving pulley 41 have the same diameter. The driven pulley 41 is fixedly connected to a rotating shaft 42 rotatably connected to the water storage tank 11. The rotating shaft 42 is fixedly connected to the cam 35, and the dust cover 15 is rotatably connected to the rotating shaft 42. Because the toothed belt 40 connects the driving pulley 39 and the driven pulley 41 and have the same diameter, the driving pulley 41 and the driven pulley 39 rotate synchronously, thereby ensuring that the drive rod 27 and the cam 35 rotate at the same angular velocity.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
