The turbine wing fan in the vacuum pump rotates, the upper air guide pipe of the vacuum pump absorbs the gas in the cylinder, the suction pipe of the cylinder absorbs the high-temperature flue gas in the heating furnace, and the high-temperature flue gas enters the cylinder.

[0015] (2) The present invention arranges a fan device so that the connecting plate, long rod, leak-proof tube, strip fan, disc and short tube cooperate with the long tube. The strip fan fans the airflow in the heating furnace, allowing the hot airflow to evenly dry the ore powder in the material box, thereby preventing the ore powder in the material box from being unevenly dried and causing a poor drying effect. In addition, under the action of friction, the shaking of the long rod during rotation is reduced, thereby preventing the long rod from shaking violently during rotation and causing the strip fan to be easily damaged.

[0016] (3) The present invention sets an anti-wear device so that the short rod, square plate, circular plate, cotton ring, sheet ring and arc-shaped elastic strip cooperate with the cotton block. The cotton ring wipes the lubricating oil evenly on the leak-proof tube, so that the long rod can rotate smoothly in the leak-proof tube, preventing the long rod from rotating and getting stuck in the leak-proof tube, causing the equipment to run unsmoothly. Moreover, under the elastic force of the arc-shaped elastic strip, the cotton block rotates tightly against the short tube, and the cotton block will be smeared on the short tube, preventing the short tube from rotating in the long tube and causing large wear and tear, which will cause the equipment parts to be easily worn out.
