Description

Technical Field

[0001] The utility model relates to the technical field of flotation separation, in particular to a forced circulation rapid flotation separation device. Background Art

[0002] At present, the equipment used for mineral flotation separation mainly includes two categories of equipment: flotation machines and flotation columns. Among them, flotation machines are relatively suitable for the flotation of coarse-grained minerals and are widely used in industrial practice. They can be mainly divided into mechanical stirring flotation machines and air flotation machines. Self-aspirated mechanical stirring flotation machines aerate and stir the slurry by the rotation of the impeller or the rotor. Aerated stirring flotation machines are flotation machines that combine mechanical stirring with external air pressure. Compressed air flotation machines use compressed air sent by an external compressor to aerate and stir the slurry. Gas precipitation flotation machines change the gas pressure in the slurry to precipitate gas from the slurry to disperse bubbles and stir the slurry.

[0003] Flotation machines generally use flotation separation method, which is a method of blowing air or nitrogen into the test solution under certain conditions to generate bubbles, so that the mineral particles to be separated and enriched in the solution are adsorbed or absorbed on it and float to the liquid surface with the bubbles, thereby separating them from the mother liquor. When separating the foam, some mineral particles will adhere to the surface of the scraper, and some existing flotation separation devices do not separate the foam thoroughly during separation, and discharge the mineral particles together with water, reducing the recovery rate of the mineral particles. The scraper of a general flotation machine is located on one side of its top. When the scraper separates the foam, it can only separate the mother liquor flowing to one side of the collecting tank, and some mother liquor inside the flotation machine may move back and forth with the rotation of the scraper, resulting in the foam not being separated, the separation effect is poor, and the separation utilization rate of the mineral particles is low.

The guide block 7 cooperates with the guide groove 6 to guide the components of the scraping mechanism 5, thereby improving the smoothness of the movement of the components of the scraping mechanism 5. At the same time, the components of the scraping mechanism 5 are limited by the T-shaped setting of the guide groove 6 and the guide block 7 to prevent the components of the scraping mechanism 5 from detaching from the interior of the fixed block 2. The surfaces on both sides of the rotating shaft of the scraper 4 are fixedly connected with a first bevel gear 8, and a second bevel gear 9 is meshed on one side of the surface of the first bevel gear 8. The number of the second bevel gear 9 is the same as that of the first bevel gear 8 and they are respectively located at Above the inner wall of the flotation tank 1, the first bevel gear 8 and the second bevel gear 9 are used in linkage, and different parts are controlled to rotate by the same power source to reduce costs. A reciprocating threaded rod 10 is fixedly connected to one side of the second bevel gear 9, and a movable sleeve 11 is threadedly connected to the surface of the reciprocating threaded rod 10. The movable sleeve 11 is used in conjunction with the reciprocating threaded rod 10. A pushing mechanism 12 is provided on one side of the movable sleeve 11. The pushing mechanism 12 is located on one side of the scraper 4. The pushing mechanism 12 is used to push the foam to the side of the scraper 4 during separation, so that the scraper 4 can separate the foam, improve the separation effect and efficiency, and avoid the accumulation of some foam without separation. A side of the bottom of the movable sleeve 11 is provided There is a positioning mechanism 13, which is used in conjunction with the components of the pushing mechanism 12. The reciprocating threaded rod 10 is used to position the components of the pushing mechanism 12 to improve the use effect.

Both the fixed plate 14 and the baffle 15 are used to push the components of the pushing mechanism 12 when they are on one side. The angle of the components of the pushing mechanism 12 can be directly adjusted to improve the use effect.

[0025] The scraping mechanism 5 includes a moving groove 51 opened on one side of the fixed block 2. The number of the moving grooves 51 is consistent with that of the fixed block 2 and they are symmetrically arranged. The moving grooves 51 are inclined and connected to the guide groove 6, and the inclination angle of the moving groove 51 is consistent with that of the guide groove 6. The inner wall of the moving groove 51 is slidably connected with a moving rod 52, and a telescopic spring 53 is fixedly connected to one side of the moving rod 52. One end of the telescopic spring 53 is fixedly connected to a bottom of the inner wall of the moving groove 51. A scraping rod 54 is fixedly connected to one side of the moving rod 52. The scraping rod 54 is movably connected to the surface of the scraper 4. The device separates the minerals in the foam by rotating the scraper 4. Whenever the scraper 4 rotates to be parallel to the ground, the surface of the scraping mechanism 5 is in contact with the scraper The scraper 4 is in contact with the rod 54, and the rotation of the scraper 4 pushes the scraper rod 54 to move upward along its surface to one side. While moving, the foam remaining on the surface of the scraper 4 is scraped off, thereby improving the separation effect and preventing the foam remaining on the surface of the scraper 4 from being separated for a long time. When the scraper rod 54 moves to the top end of one side of the scraper 4, it is separated from the surface of the scraper 4 and automatically reset by the pulling force of the telescopic spring 53. While the scraper rod 54 moves, it is guided by the guide groove 6 and the guide block 7, thereby improving the smoothness of the movement of the scraper rod 54. At the same time, the guide groove 6 and the guide block 7 are set in a T-shape to limit the moving rod 52, thereby preventing the moving rod 52 from being separated from the inside of the fixed block 2, thereby improving the use effect of the scraping mechanism 5.

[0026] The pushing mechanism 12 includes a spur gear 121 rotating on one side of the movable sleeve 11. The number of the spur gears 121 is consistent with that of the movable sleeve 11. A rack plate 122 is meshed below the surface of the spur gear 121. The rack plate 122 is slidably connected to the bottom of one side of the movable sleeve 11. The rack plate 122 is movably connected to the fixed plate 14 and the baffle 15. A connecting rod 123 is fixedly connected to one side of the spur gear 121. A push plate 124 is fixedly connected to the bottom of the connecting rod 123. When the scraper 4 rotates, the reciprocating threaded rod 10 is driven to rotate through the meshing transmission of the first bevel gear 8 and the second bevel gear 9. The movable sleeve 11 is controlled to reciprocate through the reciprocating threaded rod 10. When the movable sleeve 11 drives the rack plate 122 to move to one side of the fixed plate 14, the fixed plate 14 pushes the push plate 124. The movable rack plate 122 moves the rack plate 122 to one side and meshes with the spur gear 121 to drive the connecting rod 123 to rotate outward at a small angle, driving the push plate 124 below to tilt, and at the same time drives the push plate 124 to move to the side of the scraper 4 through the movable sleeve 11, pushing the foam on the inner side of the flotation tank 1 to the outside, thereby improving the separation rate of the foam, avoiding the foam from adhering and accumulating on the inner side of the flotation tank 1 and being unable to be effectively separated, and effectively improving the separation effect of the device; when the movable sleeve 11 drives the rack plate 122 to move to the side of the baffle 15, the baffle 15 pushes the rack plate 122, so that the rack plate 122 meshes with the spur gear 121 to drive the push plate 124 to reset to be parallel to the ground, and reciprocates and cooperates with the scraper 4 to improve the separation efficiency.

[0027] The positioning mechanism 13 includes a positioning shell 131 fixed to the left and right sides of the bottom of the movable sleeve 11. The positioning shell 131 is located below the rack plate 122. The bottom of the inner wall of the positioning shell 131 is fixedly connected with a compression spring 132. The top of the compression spring 132 is fixedly connected with a positioning rod 133. The positioning rod 133 is slidably connected to the bottom of the rack plate 122. The bottom of the rack plate 122 is provided with a positioning groove 134. The number of the positioning grooves 134 is several and evenly distributed at the bottom of the rack plate 122. The top of the positioning rod 133 is movably connected to the positioning groove 134. The top of the positioning rod 133 is controlled to fit with the bottom of the rack plate 122 by the elastic force of the compression spring 132. When the rack plate 122 moves, the positioning rod 133 moves inside the multiple positioning grooves 134 along the bottom of the rack plate 122. When the position of the rack plate 122 is determined, the positioning rod 133 is embedded in the corresponding positioning groove 134 to position the rack plate 122, avoiding the angle change of the spur gear 121 due to the gravity of the push plate 124 itself when pushing the foam, so that the push plate 124 maintains a fixed angle when moving, thereby improving the use effect of the push plate 124.

[0028] It is worth noting that the flotation cell 1 proposed in this technical solution is a prior art, and its working principle and beneficial effects when used are not described in detail here.

[0029] Working principle: First, the ore pulp is floated through the flotation tank 1, and the scraper 4 is controlled by the stepper motor 3 to rotate to separate the foam and water. While the scraper 4 rotates, the water holes on its surface are set to prevent the foam-containing water from splashing out of the collection tank of the flotation tank 1. The scraper rod 54 is pushed to move according to the change of its rotation angle. While the scraper rod 54 moves, the foam remaining on the surface of the scraper 4 is scraped off to improve the utilization rate of the slurry. When one side of the scraper 4 flips over at a large angle, the scraper rod 54 is separated from the surface of the scraper 4 and automatically returns to its original position under the action of the elastic force of the telescopic spring 53, so as to facilitate scraping the surface of the scraper 4 again. While the scraper 4 rotates, the first bevel gear 8 meshes with the second bevel gear 9. The combined transmission drives the reciprocating threaded rods 10 on both sides of the inner wall of the flotation tank 1 to rotate synchronously, and the reciprocating threaded rods 10 control the reciprocating movement of the movable sleeve 11. When the movable sleeve 11 moves to one side of the fixed plate 14, the rack plate 122 is pushed by the fixed plate 14, and the push plate 124 is driven to tilt at a small angle through the meshing transmission of the rack plate 122 and the spur gear 121. Then, the movable sleeve 11 drives the push plate 124 to move outward to push the foam on the inside to the outside. When the rack plate 122 moves to one side of the baffle 15, the baffle 15 pushes the rack plate 122 back to its position and drives the push plate 124 to rotate to the original angle, so as to cooperate with the scraper 4 to improve the efficiency of foam separation. After the separation, the stepper motor 3 can be turned off.
