Description

Technical Field

[0001] This invention relates to the field of aluminum electrolysis technology, and more specifically, to a carbon slag retrieval device for aluminum electrolysis. Background Technology

[0002] Modern aluminum electrolysis employs the cryolite-alumina molten salt electrolysis method. Molten cryolite serves as the solvent, alumina as the solute, carbonaceous material as the anode, and molten aluminum as the cathode. A strong direct current is applied, and an electrochemical reaction occurs at the electrodes within the electrolytic cell at 950℃-970℃. During electrolysis, the carbon in the anode carbon block gradually oxidizes, forming a solid electrode oxidation product, namely carbon slag. Due to its relatively low density and certain porosity and high-temperature corrosion resistance, the carbon slag usually floats on the surface of the electrolyte. The presence of carbon slag in the electrolyte increases the melt resistance and power consumption, hindering the continued electrolysis reaction. Therefore, it is necessary to remove the carbon slag from the electrolytic cell promptly.

[0003] Currently, the main method for removing carbon slag is the traditional manual method. Workers use a tool similar to a sieve to scoop the carbon slag from the electrolyte in the electrolytic cell. On the one hand, manual labor is labor-intensive and there is a risk of burning at high temperatures. On the other hand, the carbon slag will float in the electrolyte during scooping, making it difficult to remove the carbon slag completely. Summary of the Invention

[0004] The purpose of this invention is to provide a carbon slag retrieval device for aluminum electrolysis, which can easily and thoroughly retrieve carbon slag in the electrolytic cell without requiring workers to manually retrieve it with tools, thus reducing the intensity of manual labor.

[0005] The embodiments of the present invention are achieved through the following technical solution: A carbon slag retrieval device for aluminum electrolysis includes a vehicle body. A lifting column is vertically arranged on one side of the vehicle body. A connecting seat is provided at the top of the lifting column. A sliding seat is provided at the end of the connecting seat away from the lifting column. The length direction of the sliding seat is consistent with the length direction of the vehicle body. A slag retrieval mechanism is slidably arranged at the bottom of the sliding seat along its own length direction. The slag retrieval mechanism includes a vertically arranged support frame. A slag retrieval component is slidably arranged inside the support frame along its own height direction. A collection box for collecting carbon slag is provided on one side of the support frame. After the slag retrieval component moves upward to its highest position, it can pour the retrieved carbon slag into the collection box. A lifting component for driving the slag retrieval component to move is provided at the top of the support frame. A sealing mechanism is also slidably arranged on the support frame along its own height direction. The sealing mechanism is located on one side of the slag retrieval component and can prevent carbon slag from moving out of the slag retrieval component. The slag retrieval component includes a slag retrieval frame and a slag retrieval bucket. The slag retrieval frame is slidably arranged... The slag-removing bucket is rotatably mounted at the bottom of the slag-removing frame, and a torsion spring is installed between the slag-removing frame and the slag-removing bucket to drive the slag-removing bucket to a vertical position. There are two sets of lifting assemblies, each set located on the top two sides of the support frame. Each lifting assembly includes a first lifting belt and a winding / unwinding device for winding or unwinding the first lifting belt. The free end of the first lifting belt is fixedly connected to the side of the slag-removing bucket away from the slag-removing frame. Both sides of the slag-removing frame are equipped with useful... The support member that limits the rotation angle of the slag-collecting bucket is such that when the first lifting belt pulls the slag-collecting bucket to a horizontal position, the slag-collecting bucket abuts against the support member; the sealing mechanism includes a baffle, the two ends of which are slidably disposed on the outer sides of the support frame, and a baffle is slidably disposed on the baffle in the horizontal direction. When the slag-collecting bucket rotates to a vertical position, the baffle is directly opposite the opening of the slag-collecting bucket. When the slag-collecting bucket rotates from the vertical position to the horizontal position, it can abut against the baffle and push the baffle to move.

[0007] Furthermore, a second take-up reel is also provided on the drive shaft, and a second lifting belt is wound on the second take-up reel. The free end of the second lifting belt is fixedly connected to the baffle. After the second lifting belt lowers the baffle to the lowest position, the first lifting belt pulls the slag bucket upward. After the first lifting belt lowers the slag bucket to the lowest position, the second lifting belt pulls the baffle upward.

[0008] Furthermore, the first lifting belt consists of a first movable section and a first lifting section. The first movable section is fixedly connected to the first take-up reel, and the first lifting section is fixedly connected to the slag-removing bucket.

On the reel, the first movable section and the second movable section have the same winding direction; when the second lifting belt lowers the baffle, the first movable section is unwound from the first take-up reel and wound in the opposite direction, and the second lifting section is unwound outside the second take-up reel. When the baffle is lowered to the lowest position, the winding directions of the first movable section and the second movable section are opposite; when the first lifting belt pulls the slag removal frame upward, the first lifting section is wound onto the first take-up reel, and the second movable section is unwound from the second take-up reel and wound in the opposite direction. When the slag removal frame is pulled to the highest position, the winding directions of the second movable section and the first movable section are the same.

[0009] Furthermore, the support member includes a support rod, which includes a first support rod and a second support rod perpendicular to each other. The first support rod is slidably disposed within the slag removal frame, and the second support rod is disposed at the end of the first support rod facing the collection box. A support plate is disposed at the end of the first support rod away from the first support rod. A compression spring is disposed between the support plate and the slag removal frame. A loosening block is disposed on the collection box. The loosening block is used to drive the second support rod to move towards the collection box and separate it from the slag removal bucket, so that the slag removal bucket can continue to rotate to pour carbon slag into the collection box.

[0010] Furthermore, the loosening block includes a connecting part and a loosening part. The connecting part is horizontally disposed on the top of the collection box and one end of the connecting part extends outside the collection box. The loosening part is vertically disposed at the end of the connecting part located outside the collection box. The bottom end of the loosening part is provided with a chamfer. After the second support rod moves upward to contact the chamfer, it can move towards the collection box under the action of the chamfer.

[0011] Furthermore, both ends of the baffle are provided with sliders, the baffle frame is provided with a sliding groove, the slider is slidably connected in the sliding groove and one end of the slider extends to the outside of the sliding groove; the support frame is provided with a reset frame, and when the baffle frame moves upward, the reset frame can drive the slider to move closer to the support frame.

[0012] Furthermore, the reset frame includes a vertical part and an arc-shaped bending part. There is a gap between the vertical part and the support frame. The top end of the vertical part is fixedly connected to the support frame through a connecting part. The top surface of the slider has an arc-shaped surface. When the stop moves upward, the arc-shaped bending part can move the slider to move it closer to the support frame.

[0013] Furthermore, the lifting column includes a bottom column and a top column. The bottom column is fixedly connected to the vehicle body, and the top column is slidably connected inside the bottom column. A lifting electric cylinder is provided between the bottom column and the top column to drive the top column to move outward from the bottom column.

[0014] Furthermore, the bottom surface of the sliding seat is provided with a sliding groove along its own length direction, and a sliding block and a motor screw assembly for driving the sliding block to move along the length direction of the sliding groove are provided in the sliding groove. The support frame is fixedly connected to the bottom of the sliding block.

[0015] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0016] 1. This invention uses a slag-removing component to remove carbon slag. After removal, the lifting component drives the slag-removing bucket to rotate to a horizontal position and then rises to the height of the collection box to facilitate pouring the removed carbon slag into the collection box. During the rotation of the slag-removing bucket, a sealing mechanism seals the opening of the slag-removing bucket to prevent the carbon slag from falling back into the electrolyte.

[0017] 2. The present invention supports the slag-collecting bucket with a support member, so that the slag-collecting bucket remains horizontal during the rising process; a loosening block is set on the collection box. When the support member rises to the height of the collection box, the loosening block can release the limiting effect of the support member on the slag-collecting bucket, so that the slag-collecting bucket can continue to rotate to pour carbon slag into the collection box.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0035] Example 1

[0036] The following is for reference Figures 1-13 To further illustrate with specific embodiments, the present invention is a carbon slag retrieval device for aluminum electrolysis, referring to... Figure 1 , Figure 2As shown, the vehicle includes a vehicle body 1. A lifting column 2 is vertically arranged on one side of the vehicle body 1. The lifting column 2 includes a bottom column 22 and a top column 23. The bottom column 22 is welded to the vehicle body 1, and the top column 23 is slidably connected inside the bottom column 22. A lifting electric cylinder 24 is arranged between the bottom column 22 and the top column 23 to drive the top column 23 to move outward from the bottom column 22. A connecting seat 21 is welded to the top of the top column 23. A sliding seat 3 is welded to 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 vehicle 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. A slag removal mechanism is installed at the bottom of the sliding block 32. Push the vehicle body 1 to the designated position outside the electrolytic cell, start the lifting cylinder 24 to drive the top column 23 to move outward to the highest position of the bottom column 22, move the slag removal mechanism to the position of the slag to be removed in the electrolytic cell, and then start the lifting cylinder 24 to move the top column 23 inward to the bottom column 22 so that the height of the slag removal mechanism is lowered and enters the designated position in the electrolytic cell. Drive the slag removal 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 removed.

[0037] Reference Figure 3 As shown, the slag removal mechanism includes a vertically arranged support frame 4, which is fixedly connected to the bottom of the sliding block 32. A slag removal component 5 is slidably mounted inside the support frame 4 along its height. A collection box 6 for collecting carbon slag is located on one side of the support frame 4. After the slag removal component 5 moves upward to its highest position, it can pour the collected carbon slag into the collection box 6. A lifting component 7 for driving the slag removal component 5 is located at the top of the support frame 4. A sealing mechanism 8 is also slidably mounted on the support frame 4 along its height, located on one side of the slag removal component 5 and capable of preventing carbon slag from moving out of the slag removal component 5. After the slag removal component 5 has finished removing the carbon slag, the sealing mechanism 8 is lowered to one side of the slag removal component 5 to prevent carbon slag from spilling during the removal of the slag removal component 5 from the electrolyte. Then, the lifting component 7 drives the slag removal component 5 to rise along the height of the support frame 4 to the height of the collection box 6, so that the carbon slag can be easily poured into the collection box 6.

[0038] Reference Figure 4 , Figure 5As shown, the slag removal assembly 5 includes a slag removal frame 51 and a slag removal bucket 52. The slag removal frame 51 is slidably disposed within the support frame 4, and the slag removal bucket 52 is rotatably disposed at the bottom of the slag removal frame 51. A torsion spring 53 is disposed between the slag removal frame 51 and the slag removal bucket 52, and the torsion spring 53 is used to drive the slag removal bucket 52 to rotate to a vertical position. There are two sets of lifting assemblies 7, which are respectively disposed on the top two sides of the support frame 4. The lifting assembly 7 includes a first lifting belt 71 and a winding / unwinding component 72 for winding or unwinding the first lifting belt 71. The free end of the first lifting belt 71 is fixedly connected to the side of the slag removal bucket 52 away from the slag removal frame 51. Supporting components 54 are provided on both sides of the slag removal frame 51 to limit the rotation angle of the slag removal bucket 52. When the first lifting belt 71 pulls the slag removal bucket 52 to rotate to a horizontal position, the slag removal bucket 52 abuts against the supporting component 54. When no external force is applied, the slag-collecting bucket 52 is in a vertical position under the action of the torsion spring 53. As the motor screw assembly 33 drives the slag-collecting mechanism to move as a whole, the slag-collecting bucket 52 can move in the electrolyte and collect carbon slag. After collection, the first lifting belt 71 is wound up by the retractor 72, which can then pull the slag-collecting bucket 52. During the pulling process, the slag-collecting bucket 52 will first rotate. When the slag-collecting bucket 52 rotates to a horizontal position, it abuts against the support 54 and cannot continue to rotate. As the first lifting belt 71 continues to pull the slag-collecting bucket 52, it can drive the slag-collecting bucket 52 and the slag-collecting frame 51 to slide synchronously along the height direction of the support frame 4, so as to lift the slag-collecting bucket 52 to the height of the collection box 6.

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

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

[0041] Reference Figure 3 , Figure 7 As shown, the sealing mechanism 8 includes a baffle 81, with both ends of the baffle 81 slidably connected to the outer sides of the support frame 4. A baffle 82 is slidably mounted on the bottom of the baffle 81 in the horizontal direction. When the slag bucket 52 rotates to the vertical position, the baffle 82 faces the opening of the slag bucket 52. When the slag bucket 52 rotates from the vertical to the horizontal position, it can abut against the baffle 82 and push the baffle 82 to move. During this process, the baffle 82 can seal the opening of the slag bucket 52, preventing carbon slag from falling out of the opening of the slag bucket 52 during its rotation.

[0042] Reference Figure 7 As shown, both ends of the baffle 82 are equipped with sliders 821, and the baffle frame 81 has a groove 811. The sliders 821 are slidably connected in the groove 811, and one end of the sliders 821 extends to the outside of the groove 811. The sliders 821 and the groove 811 are tightly fitted and have high friction, so they will not move when no external force is applied, thus ensuring that the baffle 82 can always remain in contact with the slag bucket 52 during the rotation of the slag bucket 52. The support frame 4 is equipped with a reset frame 9. When the baffle frame 81 moves upward, the reset frame 9 can drive the sliders 821 to move closer to the support frame 4. The reset frame 9 includes a vertical part 91 and an arc-shaped bend 92. A gap is left between the vertical part 91 and the support frame 4 to avoid obstructing the movement of the baffle 81. The top of the vertical part 91 is welded to the support frame 4 through the connecting part 611. The top surface of the slider 821 has an arc-shaped surface. When the baffle 81 moves upward, the arc-shaped bend 92 can move the slider 821 to move it back to its initial position towards the support frame 4. This allows the sealing mechanism 8 to still abut against the vertically positioned slag scoop 52 after the baffle 82 moves downward into the electrolyte when sealing the slag scoop 52 for the next time.

[0043] Reference Figure 8As shown, the take-up and unload component 72 includes a drive motor 721, a drive shaft 722, and a first take-up reel 723. A motor mount 724 is welded onto the support frame 4. The drive motor 721 is mounted on the motor mount 724. The drive shaft 722 is coaxially connected to the output shaft of the drive motor 721. The first take-up reel 723 is coaxially connected to the drive shaft 722. A first lifting belt 71 is wound around the first take-up reel 723. A guide frame 41 is also mounted on the support frame 4. The guide frame 41 is equipped with guide wheels. The first lifting belt 71 rests on the guide wheels to ensure that when the first lifting belt 71 pulls the slag bucket 52, it can first cause the slag bucket 52 to flip, and then continue to drive the slag bucket 52 and the slag frame 51 to rise as a whole. When the drive motor 721 is started, the drive shaft 722 is rotated, which causes the first winding reel 723 to rotate synchronously, so that the first lifting belt 71 is wound onto the winding reel, thereby pulling the free end of the first lifting belt 71, that is, the end of the first lifting belt 71 away from the winding reel, onto the slag scoop bucket 52.

[0044] Furthermore, a second take-up reel 725 is coaxially connected to the drive shaft 722, and a second lifting belt 73 is wound around the second take-up reel 725. The free end of the second lifting belt 73 is fixedly connected to the baffle 81. When the second lifting belt 73 lowers the baffle 81 to the lowest position, the first lifting belt 71 begins 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 begins to pull the baffle 81 upward.

[0045] Reference Figure 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 reel 723, and the first lifting section 712 is fixedly connected to the slag scoop bucket 52. 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 reel 725, and the second lifting section 732 is fixedly connected to the baffle 81.

[0046] Reference Figure 9 As shown, when the slag removal assembly 5 is in the slag removal state, the baffle 81 is at its highest position. At this time, the first movable section 711 is wound around the first winding reel 723, the first lifting section 712 is located outside the first winding reel 723, the second movable section 731 is wound around the second winding reel, and the second lifting section 732 is partially wound around the second winding reel 725. At this time, the winding directions of the first movable section 711 and the second movable section 731 are the same.

[0047] Reference Figure 10 , Figure 11As shown, when the drive motor 721 is started, it drives the drive shaft 722 to rotate. During the lowering of the baffle 81 by the second lifting belt 73, the second lifting section 732 unwinds to the outside of the second take-up reel 725, and the first movable section 711 first unwinds from the first take-up reel 723, then winds back onto the first take-up reel 723 after unwinding. During this process, the first movable section 711 does not apply tension to the first lifting section 712. Therefore, during the lowering of the baffle 81, the first lifting section 712 does not apply tension to the slag-removing assembly 5, thus ensuring that the slag-removing bucket 52 does not rotate prematurely before the baffle 81 reaches the electrolyte. When the baffle 81 is lowered to its 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 onto the first take-up reel 723, and the second lifting section 732 is not wound onto the second take-up reel 725.

[0048] Reference Figure 12 , Figure 13 As shown, as the drive shaft 722 continues to rotate, the first lifting belt 71 pulls the slag-collecting bucket 52 upwards, causing the first lifting section 712 to wind onto the first winding reel 723. The second movable section 731 unwinds from the second winding reel 725 and winds in the opposite direction. During this process, the second movable section 731 does not exert any pulling force on the second lifting section 732, therefore the baffle 81 will not move upwards as the slag-collecting bucket 52 rises. When the slag-collecting bucket 52 is pulled to its 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 provided on the support frame 4 on one side of the first take-up reel 723 and the second take-up reel 725. The limiting support 42 has through holes for the first lifting section 712 and the second lifting section 732 to pass through. During the unwinding and reverse winding of 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 preventing the first movable section 711 from tangling or knotting with the first lifting section 712, and the second movable section 731 from tangling or knotting with the second lifting section 732.

[0050] After the carbon slag in the slag scoop bucket 52 is poured into the collection box 6, the drive motor 721 is started and the output shaft of the drive motor 721 drives the drive shaft 722 to rotate in the opposite direction. During the reverse rotation of the drive shaft 722, the first winding reel 723 and the second winding reel 725 can 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 drive motor 721 driving the drive shaft 722 to rotate in the forward direction.

[0051] The specific process is as follows: the first lifting section 712 first unwinds from the first take-up reel 723, and the second movable section 731 unwinds from the second take-up reel 725 and winds in the opposite direction. During this process, the second movable section 731 will not apply a pulling force to the second lifting section 732. Therefore, the baffle 81 will not move upward during the descent of the slag bucket 52, so as to avoid a collision between the slag bucket 52 and the baffle 81.

[0052] When the slag scoop bucket 52 is lowered to its lowest position, the first lifting section 712 unwinds from the first take-up reel 723. As the drive shaft 722 continues to rotate in the opposite direction, the first movable section 711 begins to unwind. After unwinding, it winds back onto the first take-up reel 723. During this process, the second lifting section 732 begins to wind onto the second take-up reel 725, thereby applying a pulling force to the baffle 81 to pull the baffle 81 upward.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
