[0003] The existing ironmaking blast furnace cleaning device usually consists of a furnace mouth slag removal assembly and a fixed disc, and the furnace mouth slag removal assembly consists of a rotating disc driven by a rotating motor and a scraper translation assembly located inside the rotating disc. The scraper translation assembly inside the rotating disc controls the movement diameter of the scraper, so that different sizes of liquid outlets can be used. Then, the rotating disc is driven to rotate by the rotating motor, thereby driving the rotation of the scraper.

[0004] During the cutting process of the scraper, the scraper often breaks due to the rapid rotation of the rotating disc because of its thinness and length. This problem is particularly evident when cutting thicker slag. Therefore, multiple spare scrapers are often needed during the slag cleaning process. SUMMARY

An slag removal assembly is arranged above the scraper translation assembly. The slag removal assembly includes a slag removal motor located above the scraper translation assembly, a detachable polishing rod connected above the output shaft of the slag removal motor through a pin, and an energy supply device passing through the rotating disc.

[0007] As an improvement, the scraper translation assembly includes a sliding block passing through the rotating disc and a displacement screw passing through the sliding block, and the sliding block and the sliding groove sidewall of the rotating disc are connected by body contact sliding.

[0008] As an improvement, the sliding block is connected to the base of the slag removal motor through a bolt structure, and the slag removal motor is connected to the energy supply device through a stretchable wire coil.

[0009] As improvement, the fixed disc and the base of the rotating motor are connected by screws, and the rotating disc and the output shaft of the rotating motor are connected by screws.

[0010] As improvement, the fixed disc is provided with arc-shaped magnetic discs on both sides for adsorbing the outer wall of the iron smelting blast furnace.

[0011] As improvement, the energy supply device is detachable, and the slag removing motor is remotely controlled by a remote controller.

[0012] The device replaces the scraper with a detachable polishing rod, and drives the detachable polishing rod by a slag removing motor. BRIEF DESCRIPTION OF DRAWINGS
