[0002] Carbon residue treatment is an important step in the cryolite production process. The traditional carbon residue treatment method usually adopts flotation, but in this process, the cleaning of filter residue has always been a problem. Since the filter residue is easy to accumulate on the top of the flotation liquid, if it is not cleaned in time, it will affect the flotation effect.

[0003] Most of the flotation equipment in the prior art is only equipped with a filter residue cleaning plate that can move left and right on the top of the flotation box. However, the cleaning plate can only push the filter residue to one side of the flotation box during the movement, and then it needs to be cleaned manually. Therefore, it is less convenient to use and requires manual cleaning all the time, which is labor-intensive. In view of this, we propose a carbon residue flotation machine for cryolite production.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] The carbon slag flotation machine for cryolite production comprises a flotation box 1, and a stirring mechanism and an aeration mechanism installed in the flotation box 1. A movable plate 33 that can move left and right and up and down is installed on the top of the flotation box 1. A driving mechanism for driving the movable plate 33 to move left and right and up and down is installed on the rear outer wall of the flotation box 1. A recovery structure 4 is fixedly installed near the top of the left outer side of the flotation box 1 for recovering the filter residue generated during flotation. The recovery structure 4 comprises a recovery box 40 that is fixedly connected to the outer wall of the flotation box 1. The recovery box 40 is L-shaped and is connected to the flotation box 1 on the right side of the top. A telescopic plate 43 that can move up and down is provided on the right side of the top of the recovery box 40. A mounting chamber 44 for the telescopic plate 43 to move up and down is provided on the top of the recovery box 40. By setting the movable plate 33 that can move left and right and up and down, the filter residue floating on the top of the flotation liquid can be cleaned by the movable plate 33, and the filter residue is pushed into the recovery structure 4. The generated filter residue can be recovered by the recovery structure 4, which is convenient for quickly cleaning the filter residue generated during the flotation process and can effectively avoid the accumulation of the filter residue on the top of the flotation liquid.

[0026] It should be added that the stirring mechanism includes two symmetrically arranged turntables 12 and a plurality of stirring rods 13 fixed between the two turntables 12. The turntable 12 is fixedly connected to the inner wall of the flotation box 1 through a rotating shaft 14 coaxially fixed on its outer wall. A stirring motor 16 for driving the rotating shaft 14 to rotate is installed on the right outer wall of the flotation box 1. The aeration mechanism includes an aeration pipe 17 installed near the bottom of the flotation box 1 and an aerator 18 for supplying air into the aeration pipe 17. The design of the stirring mechanism drives the stirring rods 13 to stir through the rotation of the turntable 12, ensuring the full mixing of the carbon residue and the flotation liquid, and improving the flotation efficiency. The aeration mechanism introduces gas into the mixed liquid through the aeration pipe 17, and the bubbles formed can adhere to the carbon residue and make it float to the liquid surface, thereby realizing the effective separation of the carbon residue.

[0027] As a preferred embodiment of the present invention, the top of the telescopic plate 43 is a slope inclined to the right and downward, that is, the telescopic plate 43 can be driven to move downward by the movable plate 33, so that the movable plate 33 can push the filter residue through the telescopic plate 43 into the recovery box 40, and a plurality of limit shafts 46 are fixedly installed inside the installation bin 44, which are all plugged with the telescopic plate 43, and each limit shaft 46 is provided with a spring 45, and the two ends of the spring 45 are respectively fixedly connected to the bottom of the telescopic plate 43 and the bottom of the installation bin 44. The design of the spring 45 ensures that the telescopic plate 43 can automatically reset after the slag is discharged, and continue to block the flotation liquid.

[0028] As a preferred embodiment of the present invention, a filter screen 41 is installed inside the recovery box 40, a discharge pipe 42 is installed at the bottom, and a valve 420 is installed on the discharge pipe 42. The filter screen 41 intercepts the filter residue, and the discharge pipe 42 is used to discharge a small amount of flotation liquid entering the recovery box 40.

[0029] As a preferred embodiment of the present invention, two bottom door blocks 15 are symmetrically hingedly installed at the bottom of the flotation box 1, and two lower extension plates 10 are symmetrically fixedly connected on both sides of the bottom thereof, and a first hydraulic cylinder 11 for driving the bottom door block 15 to flip is installed on the lower extension plate 10. The bottom door block 15 can facilitate the discharge of raw materials after flotation, and it should be added that a drain pipe with a valve is installed on the rear outer wall of the flotation box 1.

[0030] As a preferred embodiment of the present invention, six legs 2 are symmetrically fixedly installed at the bottom of the flotation box 1, a support rod 20 is inserted and installed between the two middle legs 2, and a handle 200 is installed at one end of the support rod 20. The support rod 20 is used to assist the first hydraulic cylinder 11 in supporting the bottom door block 15. When opening the bottom door block 15, the support rod 20 needs to be removed first.

[0031] As a preferred embodiment of the present invention, the driving mechanism includes a linear motor 3 and a mounting plate 30 for mounting the linear motor 3. A column 31 is fixedly connected to the slider of the linear motor 3. A horizontal plate 32 is fixedly mounted on the top of the column 31. A movable plate 33 is located directly below the horizontal plate 32. A second hydraulic cylinder 34 for driving the movable plate 33 to move up and down is mounted on the horizontal plate 32. The movable plate 33 is driven to move left and right by the linear motor 3, and is driven to move up and down by the second hydraulic cylinder 34. When the movable plate 33 returns from the left side of the flotation box 1 to the right side, the movable plate 33 needs to be lifted up. It should be added that when the piston rod of the second hydraulic cylinder 34 is extended to the longest, the bottom of the movable plate 33 is flush with the bottom of the inclined surface of the telescopic plate 43.

[0032] As a preferred embodiment of the present invention, two guide shafts 35 are symmetrically fixedly connected to the top of the movable plate 33 and both pass through the horizontal plate 32. The length of the guide shafts 35 is greater than the motion range of the piston rod of the second hydraulic cylinder 34. The design of the guide shafts 35 can ensure that the movable plate 33 always maintains a stable position and direction when moving up, down, left, and right, thereby avoiding equipment failure and performance degradation caused by the displacement of the movable plate 33.

[0033] As a preferred embodiment of the present invention, when the movable plate 33 moves to the leftmost position, its left outer wall is flush with the left outer wall of the telescopic plate 43. It is ensured that the movable plate 33 can push the filter residue through the telescopic plate 43 and successfully send it into the recovery box 40.

[0034] When the carbon slag flotation machine for cryolite production of the utility model is used, first, the carbon slag and the flotation liquid are added into the flotation box 1, at which time, the stirring mechanism starts to work, and the two turntables 12 are driven by the stirring motor 16 to rotate, driving the stirring rod 13 to fully mix the carbon slag and the flotation liquid, thereby ensuring the uniformity and efficiency of the flotation process;

[0035] At the same time, the aeration mechanism also starts to work; the aerator 18 introduces gas into the aeration pipe 17 inside the flotation box 1, and the gas is released through the tiny holes of the aeration pipe 17 to form a large number of tiny bubbles. These bubbles have adhesive properties and can adhere the carbon slag particles to their surface and make them float to the liquid surface;

[0036] As the carbon residue particles float to the liquid surface, the movable plate 33 starts to work; the movable plate 33 is driven by a driving mechanism and can move left and right and up and down. When the movable plate 33 moves to the left, it pushes the filter residue on the liquid surface to the recovery structure 4;

[0037] The telescopic plate 43 in the recovery structure 4 plays a key role in this process. When the filter residue is pushed to the telescopic plate 43, since the top of the telescopic plate 43 is an inclined plane inclined downward to the right, the filter residue can smoothly slide into the recovery box 40. The telescopic plate 43 is supported by a spring 45 to ensure that it can automatically reset and continue to intercept new filter residue. At this time, the driving mechanism sends the movable plate 33 back to the right side of the flotation box 1 and repeats the leftward movement.

[0038] The filter residue entering the recovery box 40 is first intercepted by the filter screen 41 to ensure the quality of the recovered filter residue. The discharge pipe 42 installed at the bottom of the recovery box 40 is used to discharge a small amount of flotation liquid to prevent it from accumulating in the recovery box;

[0039] When the filter residue accumulates to a certain extent in the recovery box 40, the valve 420 on the discharge pipe 42 can be opened for regular cleaning to maintain the continuous working capacity of the recovery box;

[0040] During the whole flotation process, the bottom gate 15 remains closed to ensure that the carbon slag and the flotation liquid are fully mixed and reacted in the flotation box 1. When cleaning or maintenance is required, the first hydraulic cylinder 11 can drive the bottom gate 15 to flip open and discharge the remaining raw materials.

[0041] The support rod 20 plays an auxiliary role when opening the bottom door stop 15 and needs to be removed first. The entire device is stably supported on the ground by six legs 2.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
