Description

Technical Field

[0001] The invention relates to the technical field of ore dressing equipment, in particular to a flotation machine used for separating metal minerals. Background Art

[0002] Ore dressing is the process of crushing and grinding the ore according to the physical and chemical properties of different minerals in the ore, and then using gravity separation, flotation, magnetic separation, electrostatic separation and other methods to separate useful minerals from gangue minerals, and to separate various symbiotic (associated) useful minerals from each other as much as possible, remove or reduce harmful impurities, so as to obtain the raw materials needed for smelting or other industries.

[0003] Ore dressing can enrich the useful components in minerals, reduce the consumption of fuel and transportation during smelting or other processing, and make economic use of low-grade ores.

[0004] The patent with publication number CN202590948U discloses a permanent magnetic flotation machine, which includes a machine body, a main shaft assembly, a scraper assembly, a flotation tank, a temperature controller, and a stirring device. The improvement is that a magnetic levitation device is installed on the inner or outer side of the flotation tank. The magnetic levitation device consists of a drum, a magnetic system, an unloading belt, and a rotating drive mechanism. The magnetic system is installed in the inner cavity of the drum, the unloading belt is installed on the outer surface of the drum, and the rotating drive mechanism is connected to the drum. A drum-type magnetic flotation device is added inside or outside the original flotation cell to generate a multi-force field of magnetism, buoyancy, gravity, etc. in the flotation cell, so that the magnetic minerals in the flotation foam product are separated from the gangue minerals, so as to achieve the purpose of sorting, effectively avoid the situation that the gangue minerals and the target minerals are entrained with each other during the flotation process, and achieve efficient separation of magnetic minerals and non-magnetic minerals, thereby improving the grade of iron concentrate and greatly improving the metal recovery rate. In addition, during sorting, the use of this equipment can also reduce or completely eliminate the selection or scavenging operations in the traditional flotation or magnetic separation process, simplifying the production process, and has the characteristics of low energy consumption, simple operation, simplified process, stable operation, etc., with obvious efficiency improvement.

[0005] The magnetic levitation device in the above technical solution is installed on the inside or outside of the flotation tank, and selects the magnetic minerals in the flotation foam product by adsorbing the magnetic minerals. However, the magnetic levitation device is only used for adsorption, and cannot output the magnetic minerals in a timely manner. As the working time passes, the more magnetic minerals the magnetic levitation device adsorbs, the worse the adsorption effect. At the same time, the magnetic minerals accumulated on it will interfere with the efficiency of flotation, and a multi-force field such as magnetic force, buoyancy, gravity, etc. will be generated in the flotation tank, resulting in mutual interference between flotation and magnetic separation, resulting in poor effect. Therefore, a flotation machine for metal mineral separation is urgently needed to solve the above-mentioned problems. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: A flotation machine for metal mineral separation has an internal structure design of an air pipe.

[0019] A flotation machine for metal mineral separation, through the design of an outer frame mechanism, the selection drum mechanism rotates under the drive of a power mechanism, and the magnetic block is always facing downward under the action of gravity. Therefore, during the rotation of the selection drum, when the selection drum moves out of the magnetic attraction range of the magnetic block, the non-magnetic ore leaks out through the first material port, and the magnetic ore is absorbed and then leaks out through the second material port, so that the magnetic ore can also be produced in time, thereby improving the smoothness of the ore selection output.

[0031] A top cover mechanism 5 is provided above the flotation mechanism 4, and the top cover mechanism 5 includes a top cover 501, and a sixth support rod 502 for support is evenly and equidistantly fixedly connected between the top cover 501 and the outer cylinder 401; A motor 503 is fixedly connected to the middle of the upper surface of the top cover 501, the output end of the motor 503 passes through the top cover 501 and is fixedly connected to the organic column 504, and the outer side of the upper surface of the top cover 501 is evenly and equidistantly fixedly connected to the gas chamber 505; A stirring assembly for stirring is provided below the top cover 501 , and the stirring assembly extends into the second inner cylinder 406 .

[0032] The stirring assembly includes a cross-shaped cross cylinder 506, and a cylinder column 507 for support is fixedly connected between the cross cylinder 506 and the top cover 501; The interior of the cross cylinder 506 is hollow, and the four ends of the cross cylinder 506 are fixedly connected to the air pipe 508.

[0033] The upper and lower walls of the cross cylinder 506 are movably interspersed with turntables 513 through bearings. The upper and lower turntables 513 are symmetrical. The upper turntable 513 is fixedly connected to the machine column 504, and the lower turntable 513 is fixedly connected to the stirring fan 515. A disk column 514 is fixedly connected to the side between the upper and lower turntables 513, and a column frame 516 is movably connected to the outer side of the disk column 514 through a bearing. The four sides of the column frame 516 are movably connected to plug rods 517 through rotating shafts, and the end of the plug rod 517 away from the disk column 514 is movably connected to a tube plug 518 that is adapted to be inserted into the side of the cross tube 506 through a rotating shaft.

[0034] The working principle of the present invention is as follows: The ore pulp is introduced into the second inner cylinder 406, and the motor 503 is started to drive the stirring fan 515 to stir the ore pulp inside the second inner cylinder 406 through the machine column 504 and the turntable 513. At the same time, the disk column 514 rotates with the rotation of the turntable 513, and the cylinder plug 518 is movably connected with the column frame 516 through the plug rod 517, so that the cylinder plug 518 slides back and forth in the side cylinder of the cross cylinder 506. Through the internal structure design of the air pipe 508, when the cylinder plug 518 is pushed toward the air pipe 508, the air flow enters the ore pulp through the air hole 510. When the cylinder plug 518 moves away from the air pipe 508, the cross cylinder 506 is re-inflated through the air chamber 505 and the capillary 509, and the air is compressed while stirring, thereby strengthening the linkage between the mechanical structures and improving the flotation process.

[0035] Through the internal design of the air pipe 508, the air stopper 511 is fitted on the outer port of the air hole 510, so that when the tube plug 518 moves away from the air pipe 508 to inflate the inside of the cross cylinder 506, the slurry outside the air pipe 508 will not enter the air pipe 508 through the air hole 510. The existence of the air stopper 511 prevents the air hole 510 from being blocked, making the use of the device safer and more reliable.

[0036] The ore pulp is floated in the flotation mechanism 4, the medium ore leaks into the outer frame mechanism 3 on one side through the middle cylinder 404 and the middle material pipe 405, the concentrate leaks into the outer frame mechanism 3 on the other side through the outer cylinder 401 and the outer material pipe 402, and the slag is put into the distribution trough 408 through the inner material pipe 407 for output, the medium ore and the concentrate enter different outer frame mechanisms 3 respectively and are magnetically separated by the selection cylinder mechanism 2, so as to separate two types of medium magnetic ore and fine magnetic ore, so that the device can perform dual selection of flotation and magnetic separation in a distributed manner, thereby improving the fineness of ore separation.

[0037] Through the design of the outer frame mechanism 3, the selection drum mechanism 2 rotates under the drive of the power mechanism 1, and the magnetic block 207 is always facing downward under the action of gravity. Therefore, during the rotation of the selection drum 201, when the selection drum 201 moves out of the magnetic attraction range of the magnetic block 207, the non-magnetic ore leaks out through the first material port 305, and the magnetic ore is absorbed and then leaks out through the second material port 306, so that the magnetic ore can also be produced in time, thereby improving the smoothness of the ore selection output.

[0038] Due to the existence of the dust cleaning component, when some minerals adhere to the surface of the selection barrel 201, when the selection barrel 201 rotates to the upper side, the adhered minerals thereon can come into contact with the cleaning plate 110, so that the cleaning plate 110 can remove the minerals adhered to the surface of the selection barrel 201, thereby ensuring that the state of the selection barrel 201 is consistent each time magnetic separation is performed, thereby ensuring the accuracy of magnetic separation.

[0039] The rotation of the selection drum mechanism 2 is transmitted to the main column 315 through the second belt 317. Due to the existence of the shift block 316 on the main column 315, one side of the shift block 316 is raised. When the raised side of the shift block 316 is in contact with the push plate 314, it can drive the second door panel 310 to move upward, thereby opening the gap between the first door panel 308 and the ramp plate 301. Driven by the second belt 317, the shift block 316 rotates regularly, thereby driving the second door panel 310 to open regularly, so that the flotation ore product is discharged regularly, reducing accumulation and improving the smoothness of ore selection.

[0040] Through the design of the barrel selection mechanism 2, the flotation products are selected by the barrel selection mechanism 2 at the same position, which saves the space of the device, and the magnetic separation of the middlings and concentrates can be carried out simultaneously, which reduces the selection time and improves the mechanical utilization of the device.

[0041] Although 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 present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
