Abstract

The utility model provides an easy-built, easy-assembled and easy-disassembled feeding device of a rotary kiln. A steel structure framework of a feeding chute at an opening of a feeding slope is a box body. The box boy with an upward opening is placed horizontally, and a plurality of casting holes are arranged on one side of the bottom surface of the box body. A supporting flange is arranged vertically, and a steel structure supporting framework of the supporting flange is connected with the framework of the feeding chute through a bracket. A protective layer on one side of the supporting framework is formed by casting fire-resistant materials through the casting holes of the feeding chute. The feeding device enables the installing sequence of the feeding chute with casting holes to be reasonable, facilitates disassembly of the feeding chute, thereby fundamentally avoiding the early damage of the feeding device caused by poor construction quality of the fire-resistant casting materials. The nearly horizontal feeding chute is in an overhung stable state, thereby avoiding shutting down the kiln to repair and change the feeding chute, and improving operation rate and production efficiency of the rotary kiln.
