Technical Field

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

[0002] In aluminum electrolysis production, anode carbon blocks are consumable materials as the heart of the electrolytic cell. In electrolysis production, due to differences in physical properties, problems such as anode oxidation and slag are prone to occur, resulting in an increase in carbon slag in the electrolytic cell, which affects the electrolyte pressure drop in the electrolytic cell. Therefore, the carbon slag in the aluminum electrolytic cell needs to be salvaged.

[0003] Traditional carbon slag salvage methods mainly rely on manual operations. Workers usually use iron spoons or similar tools to go deep into the aluminum electrolytic cell and try to remove the carbon slag from the electrolyte. The temperature of the aluminum electrolytic cell is very high, usually exceeding 900 degrees Celsius. Workers will inevitably be burned when they salvage carbon slag in a high-temperature working environment. In addition, the temperature of the removed carbon slag is very high.

The hook 304 is hung inside the hook 305, and the bottom surface of the hook 305 is fixedly connected to a high-temperature resistant hydraulic drive box 4. By using the hydraulic lifting rod 301, the hook 304 can be driven to move, so that the hook 304 drives the hook 305 and the high-temperature resistant hydraulic drive box 4 to move up and down, and the height position of the high-temperature resistant hydraulic drive box 4 can be controlled.

[0032] The bottom surface of the transverse connecting plate 302 is fixedly connected with an oblique reinforcement rod 307, the outer surface of the oblique reinforcement rod 307 is fixedly connected with a reinforcement block 306, the inner wall of the reinforcement block 306 is fixedly connected to the output end of the hydraulic lifting rod 301, and by using the cooperation between the reinforcement block 306 and the oblique reinforcement rod 307, the transverse connecting plate 302 can be reinforced, thereby increasing the bearing capacity of the transverse connecting plate 302.

[0033] The high temperature resistant hydraulic drive box 4 is supported by high temperature resistant materials throughout, and a hydraulic driver is arranged inside the box. The high temperature resistant hydraulic drive box 4 can drive the two output shafts to extend and retract.

[0034] The dual output ends of the high temperature protection hydraulic drive box 4 are fixedly connected with the drive column 5. Two anti-stuck mechanisms 6 and a salvage bucket 8 are arranged below the high temperature protection hydraulic drive box 4.

The main water supply pipe 1103, the connecting water pipe 1104 and the spray head 1105 are all made of high temperature resistant materials to avoid the use of plastic water pipes being scalded by the heat waves emitted by the carbon slag.

[0040] Working principle: When it is necessary to salvage the carbon slag inside the aluminum electrolytic cell, first move the mobile vehicle 1 to the designated position. By starting the high temperature resistant hydraulic drive box 4, the two drive columns 5 can be driven to extend, so that the positioning connecting plate 601, the rotating block 602 and the guide groove 606 can be moved downward, and the first shear plate 703 and the second shear plate 704 can drive the two salvage buckets 8 to rotate and open with the central axis 702 as the center. By starting the hydraulic lifting rod 301, the horizontal connecting plate 302, the suspension rod 303, the hook 304, the hook 305 and the high temperature resistant hydraulic drive box 4 can be driven to rise and fall, and the height position of the salvage bucket 8 can be adjusted so that the salvage bucket 8 can be extended into the interior of the aluminum electrolytic cell, and then the high temperature resistant hydraulic drive box 4 can be started again to close the two salvage buckets 8, and the carbon slag can be salvaged. Start the hydraulic lifting rod 301 again to lift the salvage bucket 8, start the drive motor 201, and drive the drive rod 202 and the gear 203 to rotate, so that the gear ring 206 can be driven to make the carrier plate 205 drive the lifting mechanism 3 to rotate as a whole, so that the lifting mechanism 3 can drive the salvage bucket 8 to the top of the temporary storage bin 9, start the high temperature hydraulic drive box 4 to open the two salvage buckets 8 and put the carbon slag into the temporary storage bin 9. By starting the water pump 1102, the water in the water tank 1101 can be pumped out and transported into the connecting water pipe 1104 through the main water supply pipe 1103. Through the joint action of a group of spray heads 1105, water can be sprayed on the carbon slag to cool it down, speeding up the temperature reduction efficiency of the carbon slag and facilitating subsequent treatment.
