Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbide production equipment, in particular to a calcium carbide furnace charge surface dredging device. Background Technique

[0002] During the smelting process of the calcium carbide furnace, the furnace charge is filled into the top furnace mouth, gradually descends after passing through the high-temperature molten state, enters the molten pool area, and the final product - calcium carbide liquid is discharged from the tapping port. Due to the gases generated during the ore smelting process and the defects of the operation process, the smooth operation of the furnace condition is affected, and the materials are prone to form a crust at the top in the high-temperature environment. Once the crust collapses, it will pose a great danger to the workers on the furnace base operation platform and endanger their lives.

[0003] In order to avoid the formation of the crust, workers or driving equipment are used to prevent the formation of the crust on the charge surface. When using the manual operation method, the operators must work at the furnace mouth, and there are many operators. Once there is a splash, it will cause fatal injuries to many people; when using the driving equipment operation method, the distance from the furnace mouth can be a little farther, but the length of the drill rod on the equipment is limited and cannot be too far from the furnace mouth. Coupled with some protection on the driving equipment, small-scale splashes can be avoided from hurting people, but large-scale splashes will still cause fatal injuries to the operators.
