One end of the first spring 36 is fixedly connected to the inner wall of the movable groove 37. The two groups of movable blocks 31 can be gathered and fixed by the block 33, so that the smearing structure 4 is separated from the inner wall of the kettle body 1, so that when the stirring paddle 23 stirs the material inside the kettle body 1, the smearing structure 4 will not cause wear to the inner wall of the kettle body 1. The lifting block 35 can move up and down in the stirring paddle 23 under the action of the threaded shaft 25. When the block 33 is disengaged from the slot 32, the movable block 31 can be away from the stirring paddle 23 under the action of the first spring 36, so that the conduit 41 can fit the inner wall of the kettle body 1.

[0023] Furthermore, the conduit 41 is connected to the interior of the movable block 31, and the conduit 41 is in an inverted "T" shape. The outer wall of the push rod 42 fits the inner wall of the conduit 41, and the push rod 42 blocks the inside of the conduit 41. The repair agent in the movable block 31 can be applied to the inner wall of the kettle body 1 through the conduit 41, and the push rod 42 can drive the movement of the repair agent in the conduit 41.

[0024] Furthermore, one end of the abutment rod 43 passes through the catheter 41, and the other end of the abutment rod 43 is inserted into the inner side of the fixing ring 45. One end of the second spring 44 is fixedly connected to the outer wall of the catheter 41. The fixing ring 45 can be sealed by the abutment rod 43 to prevent the repair agent in the catheter 41 from leaking out.

[0027] Working principle: When in use, the repair agent is added into the movable block 31 through the feed pipe 38 and the feed port 34, and the push rod 42 can block the conduit 41, so as to prevent the repair agent inside the movable block 31 from directly flowing out through the conduit 41; When the damaged part on the inner wall of the kettle body 1 needs to be repaired, the second motor 24 is started to drive the threaded shaft 25 to rotate. The threaded shaft 25 is threadedly connected to the lifting block 35. The rotation of the threaded shaft 25 can drive the lifting block 35 to descend inside the stirring paddle 23. The lifting block 35 drives the movable block 31 to descend. The movable block 31 is away from the block 33. The block 33 can be pulled out of the slot 32. The two groups of movable blocks 31 lose the limit of the block 33 and can move away from each other under the action of the first spring 36. The lifting block 35 slides in the movable slot 37, and the movable block 31 drives the guide tube 41 to fit the inner wall of the kettle body 1. The motor 49 is started to drive the threaded rod 410 to rotate. The threaded rod 410 is threadedly connected with the abutting rod 43.

The fixing ring 45 releases the tension on the wire rope 411, and the wire rope 411 is transmitted on the wire wheel 48. At the same time, the abutting rod 43 connected to the other end of the wire rope 411 will move in the direction close to the fixing ring 45 under the action of the second spring 44. However, due to the limitation of the inner wall of the kettle body 1, the abutting rod 43 cannot extend from the inner side of the fixing ring 45. The abutting rod 43 abuts against the inner wall of the kettle body 1 under the action of the second spring 44, and the pushing rod 42 releases the blockage of the guide tube 41, and the repair agent in the movable block 31 enters the guide tube 41 and fills the space between the pushing rod 42 and the fixing ring 45. The first motor 21 is started to drive the mounting shell 22 and the stirring paddle 23 to rotate, and the stirring paddle 23 drives the movable block 31 to rotate, and the movable block 31 drives the abutment rod 43 to rotate through the guide tube 41, and the abutment rod 43 slides along the inner wall of the kettle body 1. When the abutment rod 43 moves to the corroded and damaged part on the inner wall of the kettle body 1, there will be a gap between the abutment rod 43 and the inner wall of the kettle body 1, so the abutment rod 43 will extend from the inner side of the guide tube 41, and the first motor 21 and the second motor 24 will stop rotating at this time, and the movable block 31 and the guide tube 41 will keep a fixed position; The starting motor 49 drives the threaded rod 410 to reverse, and the threaded rod 410 drives the pushing rod 42 to move in the guide tube 41 toward the direction close to the fixing ring 45. The movement of the pushing rod 42 can push the repair agent inside the guide tube 41, so that the repair agent moves toward the fixing ring 45, and when the pushing rod 42 moves, it pulls the wire rope 411, and pulls the abutting rod 43 through the wire rope 411, so that the abutting rod 43 moves in the direction away from the fixing ring 45, and the pushing rod 42 and the abutting rod 43 move in opposite directions, and the abutting rod 43 is withdrawn from the fixing ring 45, and drives the blocking ring 46 to separate from the fixing ring 45, so that the inner side of the fixing ring 45 is unobstructed, which is convenient for the repair agent pushed by the pushing rod 42 to flow out through the fixing ring 45, and the guide tube 41 and the fixing ring 45 are both in contact with the inner wall of the kettle body 1, so when the repair agent flows out through the fixing ring 45, it can directly enter the corroded and damaged part of the inner wall of the kettle body 1, and the repair agent can be prevented from dripping downwards and causing waste; The motor 49 is started to drive the abutment rod 43 to move away from the fixing ring 45, so as to release the push on the repairing agent. The abutment rod 43 moves toward the fixing ring 45 under the action of the second spring 44. The abutment rod 43 is inserted into the fixing ring 45 together with the blocking ring 46 to block the fixing ring 45. The part of the repairing agent accumulated in the fixing ring 45 can be pushed to the corroded and damaged part of the inner wall of the kettle body 1, so that the repairing agent inside the corroded and damaged part of the inner wall of the kettle body 1 is compacted. By controlling the first motor 21 , the stirring paddle 23 can be driven to rotate slightly forward and reverse, and the conduit 41 can be driven to rotate back and forth, so that the repair agent in the damaged part can be smoothed, so that the inner wall of the kettle body 1 is smooth, and the anti-corrosion performance of the kettle body 1 can be ensured.
