Description

Technical Field

[0001] The present invention relates to the field of aluminum electrolysis waste, and in particular to a method for processing aluminum electrolysis waste. Background Art

[0002] Industrial aluminum electrolysis is carried out in an aluminum electrolysis cell, using alumina as raw material and cryolite-alumina molten salt as the aluminum electrolyte. When direct current is passed into the aluminum electrolysis cell containing cryolite-alumina melt, the anodic process of aluminum electrolysis occurs on the carbon anode, producing carbon dioxide gas, and the cathodic process of aluminum electrolysis occurs on the carbon cathode, precipitating aluminum. This method is called cryolite-alumina electrolysis. The waste slag generated by the maintenance and disposal of the electrolysis cell during the aluminum electrolysis process is converted into spent cathode carbon blocks. Harmful substances will remain on the surface of the spent cathode carbon blocks, so alkaline leaching solution is needed to treat the harmful substances on their surface.

[0003] In the process of processing waste cathode carbon blocks, the following problems still exist:

[0004] 1. Before processing the spent cathode carbon blocks, the traditional method is to directly place the spent cathode carbon blocks to be processed in a cylinder. At this time, the spent cathode carbon blocks to be processed will pile up together, thereby affecting the alkaline leaching treatment effect of the spent cathode carbon blocks.

[0005] 2. In the process of processing the waste cathode carbon blocks, the cylinder containing the waste cathode carbon blocks is generally placed directly into the alkaline leaching solution for immersion. During the immersion process, the alkaline leaching solution is always in a static state, thereby reducing the effect of alkaline leaching of the waste cathode carbon blocks.

[0037] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further elaborated.

[0038] A method for processing aluminum electrolysis waste, the processing of aluminum electrolysis waste specifically includes the following steps:

[0039] S1. Obtain waste: The waste cathode carbon block is obtained from the waste residue generated during the maintenance and abandonment of the electrolytic cell in the aluminum electrolysis process.

[0040] S2. Place the waste: Place the waste cathode carbon block obtained in step S1 on the cleaning device 4.

[0041] S3. Waste treatment: Finally, move the cleaning device 4 with the waste cathode carbon block placed in step S2 into the placement box 2, and perform alkali leaching treatment on the waste cathode carbon block.

[0042] Refer to Figure 2 , in the process of processing aluminum electrolysis waste using the aluminum electrolysis waste processing method of the above steps S1-S3, it also specifically involves an aluminum electrolysis waste processing device, including a fixed platform 1, a placement box 2, a fixing device 3 and a cleaning device 4. A placement box 2 is provided on the top of the fixed platform 1, a fixing device 3 is provided above the placement box 2 on the top of the fixed platform 1, and a cleaning device 4 is provided on the fixing device 3;

[0043] Refer to Figure 2 , Figure 3 and Figure 5The fixing device 3 includes a threaded rod 31, a fixed rod 32, a horizontal plate 33, a No. 1 chain 34, a forward and reverse motor 35, a movable plate 36 and an adjustment assembly 37. The top of the workbench is rotatably provided with two threaded rods 31 and two fixed rods 32 distributed in a matrix, and the two threaded rods 31 and the two fixed rods 32 are placed diagonally. The threaded rods 31 and the fixed rods 32 are jointly provided with a horizontal plate 33, and the threaded rods 31 and the horizontal plate 33 are connected by threads, and the fixed rods 32 and the horizontal plate 33 are connected by sliding. A movable sprocket is fixedly installed between the two threaded rods 31 and above the horizontal plate 33, and the movable sprockets are connected by a No. 1 chain 34 for transmission. The top of the fixed platform 1 is fixedly connected to the bottom of one of the threaded rods 31 by the forward and reverse motor 35, and a sliding groove is provided at the bottom of the horizontal plate 33. The movable plate 36 is slidably connected in the sliding groove by a translational electric slider, and an adjustment assembly 37 is provided at the bottom of the movable plate 36.

[0044] See Figure 2 A material holding box 11 is provided on the top of the fixed platform 1 and on the right side of the placement box 2;

[0045] In the original state, first put the alkaline leaching solution for processing the waste cathode carbon blocks into the placement box 2, and move the electric slider to drive the movable plate 36 to the leftmost side of the sliding groove, so that the adjustment component 37 drives the cleaning device 4 to be located on the left side. After being located on the left side, the cleaning device 4 is driven by the adjustment component 37 to tilt downward from left to right at a certain angle, so as to facilitate the rapid loading of the waste cathode carbon blocks that need to be processed. When the loading is completed, the adjustment component 37 drives the cleaning device 4 to return to its original position, and now the electric slider drives the movable plate 36 to the center position of the sliding groove, so that the cleaning device 4 for placing the waste cathode carbon blocks is located directly above the placement box 2, and then the forward and reverse motors 35 are started to rotate forward, and the forward and reverse motors 35 drive one of the threaded rods 31 to rotate. At this time, under the limit of the fixed rod 32, the horizontal plate 33 is moved downward, and the horizontal plate 33 enables the adjustment component 37 to drive the cleaning device 4 for placing the waste cathode carbon blocks to move into the placement box 2 (such as Figure 9As shown in the figure, the waste cathode carbon blocks are processed by the alkali leaching solution in the placement tank 2. After the processing is completed, the positive and reverse motor 35 rotates in reverse. The horizontal plate 33 causes the adjustment component 37 to drive the cleaning device 4 for the processed waste cathode carbon blocks to return to the original position. Finally, the translation electric slider drives the moving plate 36 to move to the rightmost side of the sliding groove, so that the adjustment component 37 drives the cleaning device 4 for the processed waste cathode carbon blocks to be directly above the material storage box 11. At this time, the adjustment component 37 drives the cleaning device 4 to tilt downward at a certain angle from left to right, facilitating the rapid feeding of the processed waste cathode carbon blocks, and the waste cathode carbon blocks are fed into the material storage box 11. The provided material storage box 11 can collect the processed waste cathode carbon blocks, preventing the processed waste cathode carbon blocks from scattering everywhere and thus having a certain impact on the working environment.

[0046] Refer to Figure 3 and Figure 4 As shown in FIGS. and, the adjustment component 37 includes a mounting plate 371, a rotating rod 372, a swing plate 373, a transmission gear 374 and a rack plate 375. A mounting plate 371 with a downward-opening U-shaped structure is fixedly installed at the bottom of the moving plate 36. A rotating rod 372 is rotatably arranged between the front and rear vertical sections of the mounting plate 371. A swing plate 373 is fixedly installed on the rotating rod 372. The bottom of the swing plate 373 is fixedly connected to the top of the cleaning device 4. The rear end of the rotating rod 372 passes through the mounting plate 371 and is fixedly installed with a transmission gear 374. A moving groove is opened on the vertical section at the rear side of the mounting plate 371. A rack plate 375 is slidably connected in the moving groove through a moving electric slider. The rack plate 375 and the transmission gear 374 are meshed for transmission;

[0047] When it is necessary to load or unload the waste cathode carbon blocks, the moving electric slider can be started. The moving electric slider drives the rack plate 375 to move in the moving groove. The rack plate 375 causes the transmission gear 374 to drive the rotating rod 372 to rotate at a certain angle. The rotating rod 372 causes the swing plate 373 to drive the cleaning device 4 to tilt downward at a certain angle from left to right, facilitating the loading and unloading of the waste cathode carbon blocks and thus improving the working efficiency of the equipment.

[0048] Refer to Figure 2 、 Figure 6 and Figure 9, the cleaning device 4 includes a U-shaped plate 41, a rotating rod 42, a circular cover plate 43, a rotating shaft 44, a circular cylinder 45, a hollow placement frame 46, a fixing component 47, a moving component 48 and a driving component 49. A U-shaped plate 41 with a downward opening is fixedly installed below the adjusting component 37. A rotating rod 42 is arranged between the two vertical sections of the U-shaped plate 41. Rotating shafts 44 are fixedly installed at both the left and right ends of the rotating rod 42 through circular cover plates 43. The rotating shafts 44 are rotationally connected to the vertical sections of the U-shaped plate 41. A circular cylinder 45 is sleeved on the rotating rod 42. Fan-shaped hollow placement frames 46 are fixedly installed on the side wall of the circular cylinder 45 along the circumference at equal intervals. Circular through holes are evenly formed in the side wall of the hollow placement frame 46. Fixing components 47 are symmetrically arranged at both the left and right ends of the rotating rod 42. Limiting holes are symmetrically formed at both the left and right ends of the rotating rod 42. Moving components 48 are arranged in the limiting holes. A driving component 49 is also arranged at a position close to the right side of the U-shaped plate 41;

[0049] When the adjusting component 37 drives the cleaning device 4 to be located on the left side, and the adjusting component 37 drives the cleaning device 4 to tilt downward at a certain angle from left to right, the moving component 48 on the left side no longer limits the fixing component 47 on the left side. At this time, move the fixing component 47 to make the hollow placement frame 46 in an open state. Next, the waste cathode carbon blocks to be processed can be quickly loaded into the hollow placement frame 46. Through the partitioned feeding of the hollow placement frame 46 provided, the waste cathode carbon blocks are prevented from piling up, thereby affecting the alkali leaching treatment effect of the waste cathode carbon blocks. After the feeding is completed, move the fixing component 47 to block the hollow placement frame 46. When the adjusting component 37 drives the cleaning device 4 for placing the waste cathode carbon blocks into the placement box 2, the driving component 49 provided makes the rotating shaft 44 and the circular cover plate 43 drive the rotating rod 42 to rotate. The rotating rod 42 makes the circular cylinder 45 drive the hollow placement frame 46 to rotate. During the rotation process, the waste cathode carbon blocks in the hollow placement frame 46 will move sufficiently, so as to further improve the alkali leaching effect. At the same time, through the arrangement of multiple hollow placement frames 46 in a windmill structure, when the circular cylinder 45 drives the hollow placement frame 46 to rotate, the alkali leaching solution can be stirred to move, and thus the harmful substances on the waste cathode carbon blocks can be better rotated and separated.

[0050] Refer to Figure 6 and Figure 7 , the fixing component 47 includes a limiting plate 471, an annular plate 472 and a fan-shaped baffle 473. Limiting plates 471 are fixedly installed at both the left and right ends of the rotating rod 42 and on the side far from the hollow placement frame 46. An annular plate 472 in contact with the limiting plate 471 is rotatably arranged at one end of the rotation close to the hollow placement frame 46. Limiting grooves are symmetrically formed on the upper and lower inner ring surfaces of the annular plate 472. Fan-shaped baffles 473 corresponding to the hollow placement frame 46 are fixedly installed on the outer ring surface of the annular plate 472 along the circumference at equal intervals;

[0051] Refer to Figure 10 , in which a spline groove is provided on the outer arc surface of one of the sector baffles 473, and a regulating rod 474 with a spline-shaped end is detachably arranged in the spline groove;

[0052] Refer to Figure 6 and Figure 7 , the moving assembly 48 includes an electric telescopic rod 481, a frustum block 482, a clamping rod 483, a pressing plate 484 and a return spring 485. An electric telescopic rod 481 is fixedly installed in the limiting hole. A frustum block 482 is fixedly installed at one end of the electric telescopic rod 481 close to the vertical section of the U-shaped plate 41. The small-diameter end of the frustum block 482 is away from one end of the electric telescopic rod 481. Clamping rods 483 matched with the limiting grooves are symmetrically arranged up and down on the side wall of the rotating rod 42. A pressing plate 484 with an arc-shaped structure at both left and right ends is fixedly installed at one end of the clamping rod 483 located in the limiting hole. The pressing plate 484 and the side wall of the limiting hole are connected by a return spring 485;

[0053] When the adjusting assembly 37 drives the cleaning device 4 to be located on the left side, and the adjusting assembly 37 drives the cleaning device 4 to tilt downward at a certain angle from left to right, start the electric telescopic rod 481. The electric telescopic rod 481 makes the frustum block 482 move in the limiting hole, so that the frustum block 482 no longer presses the pressing plate 484. At this time, under the action of the return spring 485, the pressing plate 484 drives the clamping rod 483 to disengage from the limiting groove and no longer limit the annular plate 472. At this time, put the spline-shaped end of the regulating rod 474 into the spline groove on the leftmost sector baffle 473. After placing, move the regulating rod 474 to rotate. The regulating rod 474 makes the sector baffle 473 drive the annular plate 472 to rotate to a certain position, so that the hollow placing frame 46 is in an open state. Next, the waste cathode carbon block to be processed can be quickly loaded into the hollow placing frame 46. After the loading is completed, move the regulating rod 474 to drive the sector baffle 473 to return to its original position. Finally, use the electric telescopic rod 481 again to make the clamping rod 483 limit the annular plate 472. Finally, remove the regulating rod 474. When the waste cathode carbon block after treatment needs to be unloaded, move the moving assembly 48 and the fixing assembly 47 on the right side, and the steps are the same as above.

[0054] ​​​​, the driving component 49 includes a driving motor 491, a first bevel gear 492, a moving rod 493, a second bevel gear 494 and a second chain 495. A driving motor 491 is fixedly installed at the top of the horizontal section on the right side of the C-shaped plate 41. A first bevel gear 492 is fixedly installed on the output shaft of the driving motor 491. A moving rod 493 is rotatably arranged on the vertical section on the right side of the C-shaped plate 41. A second bevel gear 494 is fixedly installed on the moving rod 493. The first bevel gear 492 and the second bevel gear 494 are in meshing transmission. The right side of the rotating shaft 44 passes through the vertical section of the C-shaped plate 41 and extends outward. Fixed sprockets are fixedly installed on the rotating rod 42 and the moving rod 493. The two fixed sprockets are connected by a second chain 495 in transmission connection;

[0055] After the adjusting component 37 drives the cleaning device 4 for placing waste cathode carbon blocks into the placing box 2, the driving motor 491 is started. The driving motor 491 makes the first bevel gear 492 drive the second bevel gear 494 to rotate. The second bevel gear 494 makes the moving rod 493 drive the second chain 495 to rotate. The second chain 495 makes the rotating shaft 44 and the circular cover plate 43 drive the rotating rod 42 to rotate.

[0056] During specific operation:

[0057] First step: In the original state, first put the alkali immersion liquid for treating waste cathode carbon blocks into the placing box 2. The translation electric slider drives the moving plate 36 to move to the leftmost side of the sliding groove, so that the adjusting component 37 drives the cleaning device 4 to be located on the left side. After being located on the left side, the moving electric slider is started. The moving electric slider drives the rack plate 375 to move in the moving groove. The rack plate 375 makes the transmission gear 374 drive the rotating rod 372 to rotate a certain angle. The rotating rod 372 makes the swing plate 373 drive the cleaning device 4 to tilt downward at a certain angle from left to right. Next, the electric telescopic rod 481 is started. The electric telescopic rod 481 makes the frustum block 482 move in the limiting hole, so that the frustum block 482 no longer presses the pressing plate 484. At this time, under the action of the return spring 485, the pressing plate 484 drives the clamping rod 483 to disengage from the limiting groove and no longer limit the annular plate 472. At this time, the spline-shaped end of the adjusting rod 474 is placed into the spline groove on the leftmost sector-shaped baffle 473. After placing, the adjusting rod 474 is rotated. The adjusting rod 474 makes the sector-shaped baffle 473 drive the annular plate 472 to rotate to a certain position, so that the hollow placing frame 46 is in an open state. Next, the waste cathode carbon blocks to be processed can be quickly loaded into the hollow placing frame 46, which is convenient for loading the waste cathode carbon blocks.

[0058] In the second step, when the loading is completed, the adjusting component 37 drives the cleaning device 4 to return to its original position. At this time, the electric slider is moved horizontally to drive the moving plate 36 to the center position of the sliding groove, so that the cleaning device 4 for placing the waste cathode carbon blocks is located directly above the placement box 2. Next, the forward and reverse motors 35 are started to rotate forward. The forward and reverse motors 35 drive one of the threaded rods 31 to rotate. At this time, under the limit of the fixed rod 32, the horizontal plate 33 moves downward. The horizontal plate 33 enables the adjusting component 37 to drive the cleaning device 4 for placing the waste cathode carbon blocks to move into the placement box 2 (as shown in FIG. Figure 9 As shown) at this time, the drive motor 491 is started, and the drive motor 491 causes the No. 1 bevel gear 492 to drive the No. 2 bevel gear 494 to rotate, and the No. 2 bevel gear 494 causes the moving rod 493 to drive the No. 2 chain 495 to rotate, and the No. 2 chain 495 causes the rotating shaft 44 and the circular cover plate 43 to drive the rotating rod 42 to rotate, and the rotating rod 42 causes the circular cylinder 45 to drive the hollow placement frame 46 to rotate, and during the rotation process, the waste cathode carbon blocks in the hollow placement frame 46 will move fully, so as to further improve the effect of alkaline leaching, and the waste cathode carbon blocks are processed by the alkaline leaching liquid in the placement box 2. When the processing is completed, the forward and reverse motors 35 reverse, and the horizontal plate 33 causes the adjustment component 37 to drive the cleaning device 4 that has processed the waste cathode carbon blocks to return to its original position.

[0059] The third step is to finally translate the electric slider to drive the movable plate 36 to the rightmost side of the sliding slot, so that the adjustment component 37 drives the cleaning device 4 that has processed the waste cathode carbon blocks to be located directly above the material holding box 11. At this time, the cleaning device 4 is driven by the set adjustment component 37 to tilt downward from left to right at a certain angle, so as to facilitate the rapid unloading of the processed waste cathode carbon blocks and unload them into the material holding box 11. The processed waste cathode carbon blocks can be collected through the set material holding box 11 to avoid the processed waste cathode carbon blocks from being scattered everywhere and causing a certain impact on the working environment.
