A discharge pipe 10 is fixedly connected to the side wall of the blast furnace 6. A support column 1 is fixedly connected to the bottom surface of the support plate 2. A feed pipe 7 is fixedly connected to the top of the blast furnace 6. An exhaust pipe 8 is fixedly connected to the top of the blast furnace 6. A cap 11 is provided on the top of the feed pipe 7. By using an electric push rod 35 and a cleaning ring 310, the cleaning ring 310 can be automatically cleaned by the electric push rod 35 to remove the residual slag from the inner wall of the slag discharge pipe 4, thus reducing the amount of cleaning work required.

[0023] During use, when it is necessary to clean the residual waste residue in the inner wall of the slag discharge pipe 4, the electric push rod 35 is activated. The electric push rod 35 drives the fixed plate 36, which in turn drives the connecting plate 37. The connecting plate 37 drives the positioning ring 38, which in turn drives the connecting strip 39, thereby driving the cleaning ring 310. The cleaning ring 310 cleans the residual waste residue in the inner wall of the slag discharge pipe 4 and removes the waste residue from the slag discharge pipe 4. After cleaning, the electric push rod 35 retracts the positioning ring 38 to its original position. At the same time, the dust removal ring 34 cleans the output shaft of the electric push rod 35 to prevent impurities from adhering to the output shaft of the electric push rod 35, reducing the amount of cleaning work required. The pipe is then fixedly connected to the air inlet pipe 32, and the air volume of the fan is delivered to the air inlet pipe 32 through the pipe, which in turn delivers it to the mounting shell 31 to cool the electric push rod 35.

When maintenance of the electric push rod 35 is required, the fixing cover 91 can be easily opened to maintain the electric push rod 35, preventing the electric push rod 35 from malfunctioning after prolonged use and affecting its operation.

[0025] During operation, when it is necessary to clean the residual waste residue on the inner wall of the slag discharge pipe 4, the electric push rod 35 is activated. The electric push rod 35 drives the fixed plate 36, which in turn drives the connecting plate 37. The connecting plate 37 drives the positioning ring 38, which in turn drives the connecting strip 39, thereby driving the cleaning ring 310. The cleaning ring 310 cleans the residual waste residue on the inner wall of the slag discharge pipe 4, removing the waste residue from the slag discharge pipe 4. After cleaning, the electric push rod 35 retracts the positioning ring 38 to its original position. At the same time, the dust removal ring 34 cleans the output shaft of the electric push rod 35 to prevent impurities from adhering to the output shaft, reducing the amount of cleaning work required. The pipe is then fixedly connected to the air inlet pipe 32, and the air volume of the blower is adjusted. The air is supplied through a pipe to the air inlet pipe 32, and then to the mounting housing 31 to cool the electric push rod 35. The mounting housing 31 is made of heat insulation board. When it is necessary to maintain the electric push rod 35, press the locking block 96 to separate the locking block 96 from the locking eye 97, and then pull the fixing cover 91 to separate the locking plate 93 from the locking shell 98, thereby opening the fixing cover 91 and maintaining the electric push rod 35. After maintenance, close the fixing cover 91 again, so that the locking plate 93 is inserted into the locking shell 98, and the locking block 96 is pushed into the locking eye 97 by the connecting spring 94, thereby fixing the fixing cover 91. Then, the fixing magnet 95 is used to attract and fix it to the inner wall of the locking shell 98, further improving the stability of the fixing cover 91. The locking shell 98 is made of a magnetically attractive material.
