Description

Technical Field

[0001] The utility model belongs to the technical field of acidizing kilns, in particular to an acidizing kiln feeding spiral structure. Background Art

[0002] Currently, the acidification kiln feed spiral structure is widely used in conveying equipment in the lithium salt industry. Its main structure consists of a main shaft, blades, and cutter heads. When conveying materials such as powdered mixed concentrated sulfuric acid, the blades are damaged by sulfuric acid corrosion, and the cutter heads are worn by the material. In existing acidification kiln feed spiral structures, the cutter heads are welded to the main shaft along with the blades. This means that if the cutter heads and blades are damaged, they must be removed along with the main shaft for replacement, making replacement of the cutter heads and blades relatively cumbersome.
