[0002] The cleaning of prebaked anode carbon blocks is an important part of the carbon block cleaning process in aluminum electrolysis production. This is mainly because during the roasting process, coke will form on the surface of the anode carbon block. These coke materials need to be removed to ensure the appearance quality of the anode carbon block. If the coke materials on the surface of the anode carbon block are not removed, it may affect the working condition of the electrolytic cell, resulting in instability in the electrolysis process, affecting the efficiency of aluminum electrolysis and the quality of aluminum. At present, the conventional cleaning of prebaked anode carbon blocks adopts an automated production line, but in order to ensure the cleaning quality of large carbon blocks, manual review and cleaning will be adopted in the carbon block warehouse, that is, the carbon block is stood on its side with the carbon bowl facing forward. During this process, the end face pressed against the ground is difficult to be cleaned, and there is a risk of the carbon block overturning, posing a threat to the personal safety of the cleaning workers.

DETAILED DESCRIPTION

[0017] Example 1: Figure 1-Figure 3As shown, the utility model provides a pre-baked anode carbon block cleaning and lifting structure, including a lifting block 14, an adjustable telescopic arm, an adjusting connecting rod 9, an embedding tube 8, a supporting frame 4 and a side pressure support rod, and two upper support rods 2 and two lower support rods 5 that press against the carbon block 6 are welded on the upper and lower sides of the front end surface of the supporting frame 4 respectively, and a snap-fit block 3 is provided between the front ends of the two upper support rods 2, which are snapped to the left and right sides of the upper end of the carbon block 6 to prevent the carbon block 6 from detaching to the left or right, and the upper end of the supporting frame 4 is provided with an adjustable telescopic arm extending horizontally forward, and the middle part of the adjustable telescopic arm is provided with a lifting block 14 for lifting, and a lifting hole 13 for connecting with the hook of the lifting equipment is horizontally penetrated on the lifting block 14, and the front part of the adjustable telescopic arm is provided with an adjusting connecting rod 9, and the lower end of the adjusting connecting rod 9 is provided with an embedding tube 8 extending horizontally backward and used to be inserted into the carbon bowl 7 of the carbon block 6.

[0018] Among them, the adjustable telescopic arm includes a main sleeve 1, a load-bearing telescopic rod 12, an adjusting screw 10, a first nut 15, a hexagonal block 16 and a second nut 17. The main sleeve 1 is fixedly arranged at the upper end of the load-bearing frame 4 and extends horizontally forward. The front end of the main sleeve 1 is embedded with the load-bearing telescopic rod 12, and a parallel adjusting screw 10 is provided below the load-bearing telescopic rod 12. The load-bearing telescopic rod 12 and the adjusting screw 10 respectively pass through the adjusting connecting rod 9. The rear end of the adjusting screw 10 passes through the hanging block 14 on the main sleeve 1 and the first nut 15 and the hexagonal block 16 are respectively provided on the front and rear sides of the hanging block 14. The front and rear sides of the adjusting screw 10 are respectively provided with a second nut 17 pressed against the adjusting connecting rod 9.

[0019] When clamped on the carbon block 6, the adjusting screw 10 passes through the adjusting connecting rod 9 and the hanging block 14 respectively, but does not form a threaded connection with the adjusting connecting rod 9 and the hanging block 14, but only passes through, that is, the inner diameter of the transverse through-holes on the adjusting connecting rod 9 and the hanging block 14 is larger than the outer diameter of the adjusting screw 10. The two second nuts 17 are adjusted with a wrench to lock the adjusting connecting rod 9 relative to the adjusting screw 10. At this time, the first nut 15 on the adjusting screw 10 is threadedly nested on the adjusting screw 10, so that the adjusting screw 10 can only rotate relative to the hanging block 14 but cannot move forward and backward.

[0020] In order to strengthen the connection between the free ends of the load-bearing telescopic rod 12 and the adjusting screw 10, a fixed sleeve 11 is flush, nested and pinned at the front ends of the load-bearing telescopic rod 12 and the adjusting screw 10. The fixed sleeve 11 also serves to limit the adjustment link 9 from detaching from the load-bearing telescopic rod 12 and the adjusting screw 10.

[0021] Among them, in order to facilitate the pulling and laying of the carbon block 6 backward during the lifting process, and to help clean the end face of the carbon block 6 that is in contact with the ground, a supporting corner block is provided at the bottom of the supporting frame 4 for the carbon block 6 to rest against the ground and extend vertically forward when it is flipped over.

[0022] When in use, the hanging block 14 is hooked by a hook of a lifting device such as a crane, which can effectively avoid the risk of the carbon block 6 overturning during the manual cleaning process. At the same time, by pulling the hanging block 14 backward, the carbon block 6 can be tilted backward. During the backward tilting process, the supporting angle block at the lower end of the supporting frame 4 will contact the ground, acting as a fulcrum, which can form a state in which the supporting frame 4 is pressed against the ground and the carbon block 6 is pressed against the supporting frame 4, which can facilitate workers to clean the end face of the carbon block 6 that is in contact with the ground. After the cleaning is completed, the carbon block 6 can be reset by pulling it forward by the lifting device. The whole process does not require the carbon block 6 to be flipped left and right, but front and back, which is also adapted to the carbon block 6 being placed in rows in the carbon block 6 warehouse.

[0023] Example 2: Based on Example 1, two second nuts 17 are directly welded to the adjusting connecting rod 9. In this way, the thread of the adjusting screw 10 can be rotated by turning the hexagonal block 16 with a wrench, driving the adjusting connecting rod 9 to move back and forth, making it easier for the embedding tube 8 to be inserted into or out of the carbon bowl 7, thereby improving operational efficiency.
