Abstract

The invention provides a calcinating shaft kiln comprehensively utilizing heat energy unit temperature field and solves the problems of the existing shaft kiln that product quality is low and heat consumption is high. The calcinating shaft kiln comprises a feeding bin, a feeding pipe, a calcinating chamber and a cooling chamber. According to the technical key points of the invention, each discharge port of a top loop shunting feeding bin is connected with the feed inlet of the respective independent unit temperature field material calcinating activate chamber through a feed air lock pipe; each chamber is internally provided with one unit temperature field combustor, the bottom of each chamber is communicated with a material integrative energy integration chamber, and is communicated with the proportion gas flow strengthening cooling chamber through a material diffusing heat exchange region, the lower part of the balance gas flow strengthening cooling chamber provided with a center cooling nozzle button and a chamber cooling nozzle button is connected with the discharging air lock device. The calcinating shaft kiln has reasonable structure design, and can be controlled accurately in material preheating, calcination and cooling process; each unit temperature field has the advantages of small calcinating region, strong flame ejection penetrating power, uniform temperature distribution in the temperature field, good product quality and low heat rate.

Description

technical field

[0001] The patent of the invention relates to a shaft kiln for roasting massive materials, especially a kind of kiln for roasting limestone, dolomite, magnesite, bauxite and other massive materials with large roasting area and high production capacity, which is beneficial to realize automatic control Comprehensive utilization of thermal energy unit temperature field roasting shaft kiln. Background technique

[0002] In recent years, various types of shaft kilns have been greatly improved in structure and operation in this technical field. For example: the vertical kiln develops from a single chamber to a double chamber structure (Maerz kiln); the arrangement of the burner develops from the peripheral setting to the peripheral combined with the central setting or along the material flow; the unloading structure develops from the spiral cone to the supporting plate structure; The material and unloading operations have been mechanized and automated.
