Description

Technical Field

[0001] This utility model relates to the field of prebaked anode manufacturing technology in aluminum electrolysis production, and in particular to a device for reducing anode cracks. Background Technology

[0002] In the aluminum electrolysis production process, prebaked anodes are a crucial consumable material, and their quality directly impacts the stability and cost of aluminum electrolysis production. During the production of green anodes, due to improper cooling processes, cracks often appear at the claw holes on the top of the carbon block. These cracks not only reduce the mechanical strength of the anode, causing it to break off and slag during electrolysis, affecting the quality of the molten aluminum, but may also lead to premature anode consumption, increasing production costs. Currently, most existing cooling methods are natural cooling or simple water cooling, which cannot precisely control the cooling rate and temperature distribution at the claw holes on the top of the carbon block, making it difficult to effectively solve the problem of cracks at the claw holes on the top of the green anode carbon block.

[0003] In summary, how to design a rapid and precise cooling device for the top claw hole of a carbon block is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a device for reducing cracks in the green anode, thus solving the problem of cracks in the claw holes at the top of the green anode carbon block that are difficult to effectively address using conventional methods.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a device for reducing cracks in the green anode, including a water collection tank, a water bath roller conveyor disposed in the water collection tank for transporting the green anode, a carbon block lifting platform disposed directly above the water bath roller conveyor, and a green anode carbon block disposed on the carbon block lifting platform; the top of the green anode carbon block has a top claw hole.

[0007] Four nozzles are installed on the top of the charcoal block lifting platform. Each nozzle is connected to a water pipe, which is supplied with water by a high-pressure water pump installed in the water collection tank.

[0008] A push-out device for adjusting the position of the green anode carbon block is provided on one side of the carbon block lifting platform.

[0009] In this embodiment, the charcoal block lifting platform further includes a frame and a telescopic cylinder or lifting screw mounted on the frame for adjusting the lifting platform's height.

[0010] Furthermore in this embodiment, a temperature sensor for detecting water temperature is also installed in the water collection tank, and the temperature sensor is connected to the controller as a signal input terminal.

[0011] Furthermore, in this embodiment, the nozzles are respectively positioned directly above the claw holes on the top of the carbon block.

[0012] Furthermore in this embodiment, the water collection tank is also replenished or replaced with cooling water via a cooling water pipe.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This invention effectively reduces cracks in the green anode carbon bowl by precisely controlling the cooling rate and temperature distribution at the claw holes on the top of the carbon block, thereby improving the quality and service life of the prebaked anode and significantly increasing the yield of green anodes. The device of this invention has a simple structure, is easy to operate, and improves the product qualification rate. Simultaneously, precise control of parameters such as water temperature and water pressure ensures the stability and reliability of the green anode cooling process, providing a strong guarantee for the large-scale production of high-quality prebaked anodes.

[0020] refer to Figure 1 and Figure 2This embodiment discloses a device for reducing cracks in the green anode, including a water collection tank 9, a water bath roller conveyor 8 installed in the water collection tank 9 for transporting the green anode, a carbon block lifting platform 1 installed directly above the water bath roller conveyor 8, and green anode carbon blocks 6 installed on the carbon block lifting platform 1; four top claw holes 7 are provided on the upper part of the green anode carbon blocks 6; four nozzles 4 are installed on the top of the carbon block lifting platform 1, each nozzle 4 is connected to a water pipe 2, and the water pipe 2 is supplied with water by a high-pressure water pump 3 installed in the water collection tank 9. The high-pressure water pump 3 can be directly installed in the water collection tank 9, and its outlet end is connected to the water pipe 2 through a delivery water pipe. The carbon block lifting platform 1 includes a frame and a telescopic cylinder or lifting screw installed on the frame for adjusting the lifting platform. A push-out device 10 for adjusting the position of the green anode carbon blocks 6 is installed on one side of the carbon block lifting platform 1; the push-out device 10 is a horizontal telescopic cylinder, and a horizontal push plate is installed at the end of its telescopic rod.

[0021] In this embodiment, a temperature sensor 5 for detecting water temperature is also installed in the water collection tank 9. The temperature sensor 5 is connected to a controller as a signal input terminal so as to use negative feedback to regulate and control the water temperature in the water collection tank 9. As one implementation method, the water temperature in the water collection tank 9 can be regulated by adding cooling water.

[0022] In specific implementation, the nozzles 4 are respectively installed directly above the claw holes 7 on the top of the green anode carbon block 6; used to cool down the claw holes 7 on the top of the green anode carbon block.

[0023] In practice, the water collection tank 9 is also replenished or replaced with cooling water through cooling water pipes.

[0024] The working process of this utility model:

[0025] The formed green anode carbon block 6 is pushed by the forming machine ejection device 10 to the carbon block lifting platform 1, ensuring that the position of the claw hole 7 on the top of the carbon block 6 corresponds accurately to the position of the nozzle 4 of the four water pipes above it according to the limit positioning and push to the fixed position; in order to achieve the position limitation of the claw hole 7 on the top of the carbon block, a limit structure can be installed before the carbon block reaches the lifting platform 1 to ensure that the claw hole of the carbon block is aligned with the nozzle.

[0026] Check the operating status of water pump 3 to ensure it is functioning normally and that its pressure and flow rate are stable. Simultaneously, use temperature sensor 5 to monitor the water temperature in water bath 9 in real time, ensuring the temperature remains above 20°C.

[0027] Cooling Stage: Activate the charcoal block lifting platform 1, allowing the charcoal blocks to slowly descend with the platform. As the charcoal blocks descend, four water pipes simultaneously spray water into the claw holes 7 at the top of the charcoal blocks, continuing until the charcoal blocks are immersed in the water bath. During the water spraying process, ensure stable water pipe pressure to guarantee uniform cooling of the four claw holes at the top of the charcoal blocks.

[0028] After the green anode carbon block 6 is cooled by water spraying, it is immersed in a water collection tank. The water in the tank completes the subsequent overall cooling of the green anode. Then, the pushing device 10 pushes it from the lifting platform 1 onto the water bath roller conveyor 8. The green anode carbon block 6 moves slowly on the water bath roller conveyor 8, achieving uniform cooling of the entire green anode during the movement.

[0029] Subsequent processing: After the green anode carbon blocks 6 are cooled and solidified in the water bath roller conveyor 8, they are transported to the calcination furnace for loading. The produced prebaked anodes are sampled and inspected, and the number and extent of the claw holes 7 on the top of the carbon blocks are counted. This data is compared and analyzed with data from before this method was adopted to continuously optimize production process parameters and further improve product quality.

[0030] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
