[0008] The storage box is rotatably installed inside the slag cleaning box, and the opening of the storage box is located directly below the slag discharge pipe.

[0009] Preferably, the connecting pipe is located outside the slag discharge pipe, and the inner surface of the connecting pipe is tightly fitted with the outer surface of the slag discharge pipe.

[0010] Preferably, a motor is installed on the top right side of the slag cleaning box, and a connecting rod is fixedly connected to the output end of the motor.

[0011] Preferably, the outer surface of the connecting rod is in a threaded structure, and the outer side of the connecting rod is threadedly connected to a moving block;

[0012] Wherein, the moving block is slidably installed up and down inside the slag cleaning box.

[0013] Preferably, an adjusting rod is rotatably mounted on the left side of the moving block, and one end of the adjusting rod away from the moving block is hingedly connected to the right side of the storage box.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the blast furnace slag cleaning structure collects the slag through the storage box, reduces the number of times the slag is cleaned, saves time and effort, and facilitates regular cleaning after the slag is collected;

[0015] The slag is discharged through the slag discharge pipe. A connecting pipe is provided to prevent the slag from falling outward, so that the slag falls into the interior of the storage box. The slag is stored in the storage box to reduce the number of cleaning times. When the storage box needs to be cleaned, the connecting pipe is driven upward by a hydraulic rod, and the connecting rod is driven to rotate by a motor, so that the connecting rod drives the moving block to move upward, and the connection between the adjusting rod and the moving block and the storage box is hinged, so that the storage box is driven to rotate by the adjusting rod during the upward movement of the moving block, and the internal slag is dumped after the storage box is rotated. As a result, the inner bottom side of the slag cleaning box is inclined, and a discharge port is opened on the left side of the bottom of the slag cleaning box, so that the slag can be discharged outward for collection and treatment after being dumped.
