A feeding device for a rotary kiln

Abstract

The invention relates to the technical field of mechanical equipment, in particular to a feeding device of a rotary kiln. The feeding device of the rotary kiln comprises a kiln body, wherein end covers are arranged at both ends of the kiln body, a bearing is tightly embedded right in the center of the end cover at the feeding end of the kiln body, a feeding pipe is tightly embedded in an inner hole of the bearing, one end of the feeding pipe is arranged outside the kiln body, a first bent material pipe, a second bent material pipe and a third bent material pipe are arranged at the other end of the feeding pipe in the axial direction, the bent material pipes are connected with discharge pipes, discharge valves are arranged between the bent material pipes and the discharge pipes, the bent material pipes and the discharge pipes are arranged in an inner cavity of the kiln body, oblique valves are arranged at the rear ends of the first bent material pipe and the second bent material pipe, and an electrical control device is connected with the oblique valves and the discharge valves. When the feeding device of the rotary kiln is used, materials can be fed automatically when the rotary kiln rotates, feeding requirements of different techniques can be met, production efficiency can be improved, and the quality can be guaranteed. The feeding device of the rotary kiln has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment industry, in particular to a feeding device of a rotary kiln. Background technique [0002] Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. [0003] The current rotary kiln usually feeds material at one end and discharges material at the other end, and the material moves forward in the kiln depending on the inclination of the rotary kiln and the rotation of the kiln. Such a structure is rather cumbersome work for some production processes that need to add materials during the production process, which not only affect...
