For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 A dust removal and slag removal component for a blast furnace comprises a feed pipe 1, a receiving hopper 2 is installed at the upper end of the feed pipe 1, a mounting block 3 is installed at the lower end of the feed pipe 1, a threaded roller 4 is threadedly connected to the receiving hopper 2 and the mounting block 3, a partition plate 13 is installed on the inner wall of the feed pipe 1, a servo motor 5 is installed on the inner wall of the feed pipe 1 through the mounting plate, a transmission shaft 6 is installed on the output end of the servo motor 5 through a coupling, a spiral stirring blade 7 and a grinding roller 8 are installed on the side wall of the transmission shaft 6, a discharge pipe 9 is installed at the lower end of the feed pipe 1, a water storage tank 10 is installed at the upper end of the discharge pipe 9, an atomizing sheet 11 is installed on the inner wall of the water storage tank 10, an air pipe 12 is installed on the inner wall of the water storage tank 10, and the air pipe 12 extends into the discharge pipe 9.

[0024] The partition plate 13 divides the inner cavity of the feeding pipe 1 into a left cavity and a right cavity. The transmission shaft 6 extends to the side wall of the left cavity to install a spiral stirring blade 7 and a grinding roller 8. The grinding roller 8 is arranged between the transmission shaft 6 and the partition plate 13, so that the transmission shaft 6 can drive the spiral stirring blade 7 to rotate, bring the charcoal to the grinding roller 8, and crush the charcoal through the grinding roller 8.

[0025] The inner cavity of the discharge pipe 9 is connected to the left cavity of the feed pipe 1 . The vertical space where the discharge pipe 9 is located is arranged between the grinding roller 8 and the partition plate 13 , so that the ground charcoal chips can be discharged through the discharge pipe 9 .

[0026] A water inlet pipe is installed at the upper end of the water tank 10, a drain pipe is installed on the side wall of the water tank 10, and control valves are installed on the side walls of the water inlet pipe and the drain pipe to facilitate adding water to or taking water out of the water tank 10.

[0027] The mounting block 3 and the receiving hopper 2 are both provided with threaded holes, the side wall of the threaded roller 4 is provided with threads matching the threaded holes, and the receiving hopper 2 is connected to the inner cavity of the feeding pipe 1, so as to facilitate fixing the feeding pipe 1 in the blast furnace.

[0028] When in use, a technician in this field places the receiving hopper 2 in the wind furnace, and then starts the servo motor 5 and the atomizing sheet 11. The charcoal in the wind furnace falls into the inner cavity of the feeding pipe 1 through the receiving hopper 2. Then the servo motor 5 drives the charcoal to move to the grinding roller 8 through the transmission shaft 6. Then the servo motor 5 drives the grinding roller 8 to grind the charcoal through the transmission shaft 6, so as to facilitate the charcoal to become carbon chips. The carbon chips fall into the discharge pipe 9. The atomizing sheet 11 atomizes the water in the water tank 10, and the atomized water is input into the discharge pipe 9 through the air pipe 12, so as to facilitate the wetting of the charcoal ash in the carbon chips and prevent the charcoal ash from splashing. For this reason, we propose to conveniently gather the charcoal into the discharge pipe 9 through the receiving hopper 2, and grind the charcoal through the grinding roller 8, so as to facilitate the transportation of charcoal chips and avoid the large size of charcoal occupying the transportation space. At the same time, it is convenient to wet the ground charcoal ash to prevent the charcoal ash from splashing.
