Description
Technical Field
[0001] This utility model relates to the field of cement production equipment technology, specifically to a feeding mechanism for the flue gas chamber of a special cement rotary kiln. Background Technology
[0002] The cement rotary kiln is a type of lime kiln in the building materials equipment category. It is primarily used for calcining cement clinker and is a core piece of equipment in both dry and wet process production lines. It is applied in cement manufacturing, metallurgy, chemical engineering, and environmental protection. In hazardous waste treatment, it achieves harmless disposal through high-temperature incineration, transforming harmful components into cement clinker components, thus offering environmental benefits. The equipment consists of a kiln body, supporting devices, and a transmission system. The kiln body is inclined and supported by rollers, and equipped with a main and auxiliary transmission system to ensure stable operation at high temperatures. Based on the heating method, it is divided into internal heating (material directly contacts the flame, maximum temperature 1600℃) and external heating (heat conduction through the kiln wall, maximum temperature 1200℃), adapting to different process scenarios. In the field of cement production equipment technology, the rotary kiln flue is a key link connecting the kiln body and the decomposition furnace. Materials need to enter the decomposition furnace from the flue through the feeding mechanism. However, traditional feeding mechanisms have technical defects, such as frequent blockages, and materials are prone to forming a crust at high temperatures, which leads to narrowing of the feeding channel. This requires shutdown for cleaning every shift, resulting in a long annual downtime loss. Utility Model Content
