Description

Technical Field

[0001] The present invention relates to the technical field of aluminum electrolysis, and in particular to a carbon slag salvaging device for aluminum electrolysis. Background Art

[0002] Modern electrolytic aluminum industry production adopts cryolite-alumina molten salt electrolysis. Molten cryolite is the solvent, alumina is the solute, carbonite is the anode, and aluminum liquid is the cathode. After a strong direct current is passed, an electrochemical reaction is carried out at the two electrodes in the electrolytic cell at 950℃-970℃. During the electrolysis process, the carbon in the anode carbon block will gradually oxidize to form a solid electrode oxidation product, namely carbon slag. Since the density of carbon slag is relatively small, it has certain porosity and high temperature corrosion resistance, and it usually floats on the surface of the electrolyte. The presence of carbon slag in the electrolyte will increase the melt resistance and power consumption, which is not conducive to the continuation of the electrolytic reaction. Therefore, it is necessary to salvage the carbon slag from the electrolytic cell in time.

[0003] Currently, the carbon slag is mainly salvaged by traditional manual salvage methods. Workers use tools similar to colander to salvage the carbon slag from the electrolyte in the electrolytic cell. On the one hand, the manual labor intensity is high and there is a risk of high-temperature burns.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] The following reference Figure 1-Figure 13 In combination with a specific embodiment, the present invention is a carbon slag salvage device for aluminum electrolysis, referring to Figure 1 , Figure 2As shown, it includes a car body 1, and a lifting column 2 is arranged on one side of the car body 1 in the vertical direction. The lifting column 2 includes a bottom column 22 and a top column 23. The bottom column 22 is welded on the car body 1, and the top column 23 is slidably connected in the bottom column 22. A lifting electric cylinder 24 for driving the top column 23 to move outward from the bottom column 22 is arranged between the bottom column 22 and the top column 23. A connecting seat 21 is welded at the top end of the top column 23, and a sliding seat 3 is welded at the end of the connecting seat 21 away from the lifting column 2. The length direction of the sliding seat 3 is consistent with the length direction of the car body 1. A sliding groove 31 is opened on the bottom surface of the sliding seat 3 along its own length direction. A sliding block 32 and a motor screw assembly 33 for driving the sliding block 32 to move along the length direction of the sliding groove 31 are arranged in the sliding groove 31, and a slag scooping mechanism is installed at the bottom of the sliding block 32. Push the vehicle body 1 to a designated position outside the electrolytic cell, start the lifting electric cylinder 24 to drive the top column 23 to move outside the bottom column 22 to the highest position, move the slag scooping mechanism to just above the position of the electrolytic cell where the slag is to be scooped, then start the lifting electric cylinder 24 to move the top column 23 toward the bottom column 22 to lower the height of the slag scooping mechanism and bring it into a designated position in the electrolytic cell, and drive the slag scooping mechanism to move along the length direction of the sliding seat 3 through the motor screw assembly 33, so that the carbon slag in the electrolytic cell can be salvaged.

[0037] Reference Figure 3 As shown, the slag scooping mechanism includes a vertically arranged support frame 4, which is fixedly connected to the bottom of the sliding block 32, and a slag scooping assembly 5 is slidably arranged in the support frame 4 along its own height direction, and a collecting box 6 for collecting carbon slag is arranged on one side of the support frame 4. After the slag scooping assembly 5 moves upward to the highest position, the scooped carbon slag can be poured into the collecting box 6. A lifting assembly 7 for driving the slag scooping assembly 5 to move is arranged on the top of the support frame 4, and a blocking mechanism 8 is also slidably arranged on the support frame 4 along its own height direction. The blocking mechanism 8 is arranged on one side of the slag scooping assembly 5 and can prevent the carbon slag from moving out of the slag scooping assembly 5. When the slag scooping assembly 5 completes the scooping of carbon slag, the blocking mechanism 8 is lowered to one side of the slag scooping assembly 5 to prevent the carbon slag from leaking during the process of the slag scooping assembly 5 being removed from the electrolyte, and then the slag scooping assembly 5 is driven by the lifting assembly 7 to rise to the height of the collecting box 6 along the height direction of the support frame 4, so as to facilitate the pouring of carbon slag into the collecting box 6.

[0038] Reference Figure 4 , Figure 5As shown, the slag scooping assembly 5 includes a slag scooping frame 51 and a slag scooping bucket 52, the slag scooping frame 51 is slidably arranged in the support frame 4, the slag scooping bucket 52 is rotatably arranged at the bottom of the slag scooping frame 51, and a torsion spring 53 is arranged between the slag scooping frame 51 and the slag scooping bucket 52, and the torsion spring 53 is used to drive the slag scooping bucket 52 to rotate to a vertical state; there are two groups of lifting assemblies 7, and the two groups of lifting assemblies 7 are respectively arranged on both sides of the top of the support frame 4, the lifting assembly 7 includes a first lifting belt 71 and a retracting member 72 for winding or unwinding the first lifting belt 71, and the free end of the first lifting belt 71 is fixedly connected to the side of the slag scooping bucket 52 away from the slag scooping frame 51; supporting members 54 for limiting the rotation angle of the slag scooping bucket 52 are arranged on both sides of the slag scooping frame 51, and when the first lifting belt 71 pulls the slag scooping bucket 52 to rotate to a horizontal state, the slag scooping bucket 52 abuts against the supporting member 54. In the absence of external force, the slag scoop bucket 52 is in a vertical state under the action of the torsion spring 53. During the process of the motor screw assembly 33 driving the slag scoop mechanism to move as a whole, the slag scoop bucket 52 can move in the electrolyte and salvage the carbon slag. After the salvage is completed, the first lifting belt 71 is rolled up by the retracting member 72, and the first lifting belt 71 can pull the slag scoop bucket 52. During the pulling process, the slag scoop bucket 52 will rotate first. When the slag scoop bucket 52 rotates to a horizontal state, it abuts against the supporting member 54 and cannot continue to rotate. During the process of the first lifting belt 71 continuing to pull the slag scoop bucket 52, it can drive the slag scoop bucket 52 and the slag scoop frame 51 to slide synchronously along the height direction of the support frame 4, so as to lift the slag scoop bucket 52 to the height of the collection box 6.

[0039] Reference Figure 5 , Figure 6 As shown, the supporting member 54 includes a supporting rod 541, which is formed by a first support rod 5411 and a second support rod 5412 that are perpendicular to each other and are integrally formed. The first support rod 5411 is slidably connected in the slag scoop frame 51, and the second support rod 5412 is located at the end of the first support rod 5411 facing the collecting box 6. A supporting sheet 5413 is provided at the end of the first support rod 5411 away from the first support rod 5411, and a compression spring 542 is provided between the supporting sheet 5413 and the slag scoop frame 51. A loosening block 61 is provided on the collecting box 6, and the loosening block 61 is used to drive the second support rod 5412 to move toward the collecting box 6 and separate from the slag scoop bucket 52, so that the slag scoop bucket 52 can continue to rotate to pour the carbon slag into the collecting box 6. Before the supporting member 54 rises to contact with the loose block 61, the second support rod 5412 of the supporting rod 541 is located at the back of the slag scoop bucket 52 under the elastic force of the compression spring 542 and can limit the rotation of the slag scoop bucket 52. After the supporting member 54 rises to the height of the loose block 61, the loose block 61 can push the second support rod 5412 toward the collecting box 6 and separate it from the slag scoop bucket 52. The slag scoop bucket 52 is no longer restricted by the supporting member 54 and can continue to rotate, so that the scooped carbon slag can be poured into the collecting box 6.

[0040] Reference Figure 6 As shown, the loosening block 61 includes a connecting portion 611 and a loosening portion 612. The connecting portion 611 is welded to the top of the collecting box 6 in the horizontal direction and one end of the connecting portion 611 extends outside the collecting box 6. The loosening portion 612 is vertically arranged at the end of the connecting portion 611 outside the collecting box 6. The bottom end of the loosening portion 612 is provided with a chamfer 6121. When the second support rod 5412 moves upward to contact with the chamfer 6121, it can move in the direction close to the collecting box 6 and disengage from the slag scoop bucket 52 under the action of the chamfer 6121, so that the slag scoop bucket 52 can rotate.

[0041] Reference Figure 3 , Figure 7 As shown, the blocking mechanism 8 includes a blocking frame 81, the two ends of which are slidably connected to the two sides of the outside of the support frame 4, and a baffle 82 is provided at the bottom of the blocking frame 81 for sliding along the horizontal direction. When the slag scoop bucket 52 rotates to a vertical state, the baffle 82 faces the opening of the slag scoop bucket 52. When the slag scoop bucket 52 rotates from a vertical state to a horizontal state, it can abut against the baffle 82 and push the baffle 82 to move. In this process, the baffle 82 can block the opening of the slag scoop bucket 52 to prevent carbon slag from falling out of the opening of the slag scoop bucket 52 during the rotation of the slag scoop bucket 52.

[0042] Reference Figure 7 As shown, both ends of the baffle plate 82 are provided with sliders 821, and the baffle frame 81 is provided with a slide groove 811, the slider 821 is slidably connected in the slide groove 811 and one end of the slider 821 extends to the outside of the slide groove 811, the slider 821 and the slide groove 811 are tightly matched and have a large friction force, and will not move when not subjected to external force, so as to ensure that the baffle plate 82 can always maintain abutment with the slag scoop bucket 52 during the rotation of the slag scoop bucket 52. A reset frame 9 is provided on the support frame 4, and when the baffle frame 81 moves upward, the reset frame 9 can drive the slider 821 to move in the direction close to the support frame 4. The reset frame 9 includes a vertical portion 91 and an arc-shaped bent portion 92. A gap is left between the vertical portion 91 and the support frame 4 to avoid obstructing the movement of the blocking frame 81. The top of the vertical portion 91 is welded to the support frame 4 through the connecting portion 611. The top surface of the slider 821 is provided with an arc-shaped surface. When the blocking frame 81 moves upward, the arc-shaped bent portion 92 can push the slider 821 to move the slider 821 back to the initial position in the direction close to the support frame 4, so that the blocking mechanism 8 can block the slag bucket 52 next time. After the baffle 82 moves downward into the electrolyte, it can still abut against the vertical slag bucket 52.

[0043] Reference Figure 8As shown, the retractable member 72 includes a driving motor 721, a driving shaft 722 and a first reel 723. A motor seat 724 is welded on the support frame 4. The driving motor 721 is mounted on the motor seat 724. The driving shaft 722 is coaxially connected to the output shaft of the driving motor 721. The first reel 723 is coaxially connected to the driving shaft 722. The first lifting belt 71 is wound around the first reel 723. A guide frame 41 is also mounted on the support frame 4. The guide frame 41 is provided with a guide wheel. The first lifting belt 71 is mounted on the guide wheel to ensure that when the first lifting belt 71 pulls the slag scoop bucket 52, it can first drive the slag scoop bucket 52 to flip over, and then continue to drive the slag scoop bucket 52 and the slag scoop frame 51 to rise as a whole. Starting the drive motor 721 drives the drive shaft 722 to rotate, which can make the first winding drum 723 rotate synchronously to wind the first pulling belt 71 onto the winding drum, so that the free end of the first pulling belt 71, that is, the end of the first pulling belt 71 away from the winding drum, pulls the slag bucket 52.

[0044] Furthermore, a second winding drum 725 is coaxially connected to the driving shaft 722, and a second lifting belt 73 is wound around the second winding drum 725, and the free end of the second lifting belt 73 is fixedly connected to the blocking frame 81; when the second lifting belt 73 lowers the blocking frame 81 to the lowest position, the first lifting belt 71 starts to pull the slag scoop bucket 52 upward; when the first lifting belt 71 lowers the slag scoop bucket 52 to the lowest position, the second lifting belt 73 starts to pull the blocking frame 81 upward.

[0045] Reference Fig. 9 As shown, the first lifting belt 71 consists of a first movable section 711 and a first lifting section 712, the first movable section 711 is fixedly connected to the first winding drum 723, and the first lifting section 712 is fixedly connected to the slag bucket 52, and the second lifting belt 73 consists of a second movable section 731 and a second lifting section 732, the second movable section 731 is fixedly connected to the second winding drum 725, and the second lifting section 732 is fixedly connected to the retaining frame 81.

[0046] Reference Fig. 9 As shown, when the slag scooping assembly 5 is in the slag scooping state, the retaining frame 81 is at the highest position, at this time, the first movable segment 711 is wound on the first winding drum 723, the first pulling segment 712 is located outside the first winding drum 723, the second movable segment 731 is wound on the second winding drum, and the second pulling segment 732 is partially wound on the second winding drum 725, and at this time, the winding directions of the first movable segment 711 and the second movable segment 731 are the same.

[0047] Reference Fig.10 , Fig.11As shown, the driving motor 721 is started to drive the driving shaft 722 to rotate, so that in the process of the second lifting belt 73 lowering the blocking frame 81, the second lifting section 732 is unwound to the outside of the second winding disk 725, and the first movable section 711 is unwound from the first winding disk 723 first, and then reversely wound on the first winding disk 723 after unwinding. In this process, the first movable section 711 will not apply a pulling force to the first lifting section 712, so the first lifting section 712 will not apply a pulling force to the slag scooping assembly 5 during the lowering of the blocking frame 81, thereby ensuring that the slag scooping bucket 52 will not rotate in advance before the blocking frame 81 reaches the electrolyte. When the blocking frame 81 is lowered to the lowest position, the winding directions of the first movable section 711 and the second movable section 731 are opposite, and at this time, the first lifting section 712 is not wound on the first winding disk 723, and the second lifting section 732 is not wound on the second winding disk 725.

[0048] Reference Fig.12 , Fig.13 As shown, during the continuous rotation of the driving shaft 722, the first lifting belt 71 pulls the slag scoop bucket 52 upward, so that the first lifting section 712 is wound onto the first winding disk 723, and the second movable section 731 is unwound from the second winding disk 725 and wound in the reverse direction. During this process, the second movable section 731 does not apply a pulling force to the second lifting section 732, so the blocking frame 81 does not move upward during the rising process of the slag scoop bucket 52. When the slag scoop bucket 52 is pulled to the highest position, the winding direction of the second movable section 731 is the same as that of the first movable section 711.

[0049] Reference Figure 8 As shown, a limiting support 42 is disposed on the support frame 4 and located on one side of the first winding reel 723 and the second winding reel 725, and a through hole is provided on the limiting support 42 for the first lifting section 712 and the second lifting section 732 to pass through. In the process of unwinding and reverse winding the first movable section 711 and the second movable section 731, the limiting support 42 can limit the first movable section 711 and the second movable section 731, thereby avoiding entanglement or knotting between the first movable section 711 and the first lifting section 712, and between the second movable section 731 and the second lifting section 732 to a certain extent.

[0050] After the carbon slag in the slag bucket 52 is poured into the collecting box 6, the driving motor 721 is started and the output shaft of the driving motor 721 drives the driving shaft 722 to rotate in the opposite direction. During the reverse rotation of the driving shaft 722, the first winding drum 723 and the second winding drum 725 can be driven to rotate synchronously. During the rotation, the state change process of the first lifting belt 71 and the second lifting belt 73 is opposite to the process of the driving motor 721 driving the driving shaft 722 to rotate forward.

[0051] The specific process is: the first lifting section 712 is first unwound from the first winding drum 723, and the second movable section 731 is unwound from the second winding drum 725 and reversely wound. During this process, the second movable section 731 will not apply pulling force to the second lifting section 732. Therefore, during the dregs scooping bucket 52 descending, the retaining frame 81 will not move upward to avoid collision between the dregs scooping bucket 52 and the retaining frame 81.

[0052] When the slag scoop 52 is lowered to the lowest position, the first lifting section 712 completes unwinding from the first winding drum 723. As the drive shaft 722 continues to rotate in the opposite direction, the first movable section 711 begins to unwind, and after unwinding is completed, it reversely winds up on the first winding drum 723. During this process, the second lifting section 732 begins to wind up on the second winding drum 725, thereby applying a pulling force to the retaining frame 81 to pull the retaining frame 81 upward.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
