Description

Technical Field

[0001] This utility model relates to the field of anode carbon block preparation technology, and in particular to a device for enhancing the surface conductivity of prebaked anode carbon blocks. Background Technology

[0002] Prebaked anode carbon blocks are one of the core materials of aluminum electrolysis cells. They are mainly used for conducting electricity and participating in electrochemical reactions. Their quality directly affects the economic benefits of aluminum electrolysis production. Prebaked anode carbon blocks are usually installed at the top of the electrolysis cell, and a strong direct current is introduced into the electrolyte through the carbon anode.

[0003] During the production of carbon blocks, it is necessary to enhance the conductivity of the carbon block surface. This is usually done by spraying, which uniformly adsorbs conductive material onto the surface of the carbon block. This method is highly efficient, but the utilization rate of the spraying method is low. During the spraying process, some conductive material powder is lost, and this lost conductive material powder cannot be recovered, resulting in a waste of resources. Utility Model Content

[0004] To overcome the problem of some conductive powder being lost during the spraying of conductive materials onto the surface of carbon blocks, which cannot be recovered and thus causes resource waste.

The lower end of the support frame body is fixedly installed with anti-slip feet. A modifier solution tank is provided between the two support frame bodies. A coal tar powder tank is provided on one side of the modifier solution tank. A powder collection tank is provided on one side of the coal tar powder tank. A trackless cylinder is fixedly installed between the two support frame bodies. A fixing component for clamping and fixing the carbon blocks is provided on the moving platform of the trackless cylinder.

[0006] Preferably, the fixing component includes a mounting bracket, which is fixedly installed between the moving platforms of the two trackless cylinders.

[0007] Preferably, a mounting plate is fixedly installed on the upper end of the slide rod, and bearing seats are fixedly installed on both sides of the upper end of the mounting plate. A roller is rotatably connected between the two bearing seats, and a spring is sleeved on the surface of the slide rod.

[0008] Preferably, an upper support frame is fixedly installed on the upper end of the trackless cylinder, and top block one, top block two and top block three are fixedly installed in the middle of the upper support frame. The surface of the roller shaft is in contact with the lower end and the two side surfaces of top block one, top block two and top block three, and the two sides of top block one, top block two and top block three are inclined surfaces.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 3This utility model provides an embodiment of a device for enhancing the surface conductivity of prebaked anode carbon blocks, including a support frame body 1 and anti-slip feet 2, as well as a modifier solution tank 4, a coal tar powder tank 5, and a powder collection tank 6. The lower end of the support frame body 1 is fixedly installed with the anti-slip feet 2. The modifier solution tank 4 is located between the two support frame bodies 1. The coal tar powder tank 5 is located on one side of the modifier solution tank 4, and the powder collection tank 6 is located on one side of the coal tar powder tank 5. A trackless cylinder 3 is fixedly installed between the two support frame bodies 1. A fixing assembly for clamping and fixing the carbon blocks is provided on the moving platform of the trackless cylinder 3. The fixing assembly includes a mounting frame 8, which is fixedly installed between the moving platforms of the two trackless cylinders 3. The upper end of the mounting frame 8... A sliding rod 9 is slidably connected. A second mounting plate 13 is fixedly installed at the lower end of the sliding rod 9. A carbon block clamp 14 is fixedly installed at the lower end of the second mounting plate 13. A first mounting plate 10 is fixedly installed at the upper end of the sliding rod 9. Bearing seats 11 are fixedly installed on both sides of the upper end of the first mounting plate 10. A roller shaft 12 is rotatably connected between the two bearing seats 11. A spring 15 is sleeved on the surface of the sliding rod 9. First, the carbon block is fixedly installed at the carbon block clamp 14. Then, the trackless cylinder 3 is started. During the movement, a modifier is applied to the surface of the carbon block and coal tar powder is adhered to enhance the conductivity. After the coal tar powder is adhered, the excess coal tar powder on the surface of the carbon block is shaken off at the top block 19. The shaken coal tar powder falls into the powder collection box 6, thus completing the recycling.

[0021] Please see Figure 3 - Figure 5 In this embodiment, an upper support frame 16 is fixedly installed on the upper end of the trackless cylinder 3. A top block 17, a top block 2 18, and a top block 3 19 are fixedly installed in the middle of the upper support frame 16. The surface of the roller shaft 12 contacts the lower ends and side surfaces of the top blocks 17, 2 18, and 3 19. The sides of the top blocks 17, 2 18, and 3 19 are inclined surfaces. The top block 17 is located directly above the modifier solution tank 4, and its lower end is flat. A drain port 7 is provided on one side of the modifier solution tank 4. The top block 2 18 is located directly above the coal tar powder tank 5. The lower end of the top block 18 is evenly distributed with grooves 20. The top block 19 is located directly above the powder collection box 6. The lower end of the top block 19 is evenly distributed with grooves 21. Under the squeezing action of the inclined side of the top block 17, the roller 12 descends, and the carbon block fixedly installed at the lower end of the carbon block clamp 14 is immersed in the modifier solution box 4. The carbon block with the modifier on its surface is then squeezed into the coal tar powder box 5 by the inclined side of the top block 18. The modifier on the surface of the carbon block adheres the coal tar powder in the coal tar powder box 5 to the surface of the carbon block.

[0022] In use, the charcoal block is first fixedly installed in the charcoal block clamp 14. Then, the trackless cylinder 3 is activated. The mounting frame 8 is fixedly installed on the moving platform of the trackless cylinder 3. The trackless cylinder 3 drives the charcoal block fixedly clamped at the lower end of the charcoal block clamp 14 to move. During the movement, the roller 12, which is rotatably set between the two bearing seats 11, first touches the inclined surface on one side of the top block 17. Under the squeezing action of the inclined surface on one side of the top block 17, the roller 12 descends. The roller 12 is installed on the upper end of the mounting plate 10. The mounting plate 10 is fixedly connected. Simultaneously, the sliding rod 9 descends, causing the carbon block clamp 14 at the lower end of the mounting plate 2 13 to descend as well. The carbon block fixedly installed at the lower end of the carbon block clamp 14 is then immersed in the modifier solution tank 4. Subsequently, it moves to the top block 3 19 in the same manner. As the roller 12 moves in the groove 2 21, it shakes the carbon block, thereby shaking off excess coal tar powder from the surface of the carbon block. This ensures that the coal tar powder is evenly distributed on the surface of the carbon block. The shaken-off coal tar powder falls into the powder collection box 6, thus completing the recycling.

[0023] When the carbon block with the modifier on its surface moves between top block 17 and top block 2 18, the unsupported roller 12 rises and returns to its original position under the action of the slide bar 9. Then, under the pressure of the inclined surface on one side of top block 2 18, it enters the coal tar powder box 5. The modifier on the surface of the carbon block adheres the coal tar powder in the coal tar powder box 5 to the surface of the carbon block. The modifier has adhesive properties and is a mature existing technology, so it will not be described in detail here. The coal tar powder has good electrical conductivity and is a mature existing technology, so it will not be described in detail here.

[0024] Then, it moves to the top block 19 in the same way. Under the pressure of the inclined surface on one side of the top block 19, the carbon block enters the powder collection box 6. The lower surface of the top block 19 has grooves 21 evenly distributed. When the roller 12 moves in the grooves 21, it shakes the carbon block, thereby shaking off the excess coal tar powder on the surface of the carbon block. This ensures that the coal tar powder is evenly distributed on the surface of the carbon block. The shaken coal tar powder falls into the powder collection box 6 to complete the recycling, avoids the waste of coal tar powder, and improves the utilization rate.

[0025] The lower end of the top block 18 has evenly distributed grooves 20. As the roller 12 moves in the grooves 20, it will cause the carbon block to undulate up and down, ensuring that enough coal tar powder adheres to the surface of the carbon block.

[0026] Through the above steps, the prebaked anode carbon block surface conductivity enhancement treatment equipment enhances conductivity by applying a modifier and adhering coal tar powder to the surface of the carbon block during the movement process. After the coal tar powder is adhered, the excess coal tar powder on the surface of the carbon block is shaken off at the top block 19. The shaken coal tar powder falls into the powder collection box 6 to complete the recycling. While ensuring the adhesion efficiency of conductive materials, the waste of coal tar powder is avoided, thereby improving the utilization rate.
