Abstract

The invention discloses an energy saving reaction furnace with characteristics of easy reaction condition control and a non-integral hollow spiral structure. The energy saving reaction furnace comprises three units such as an electric feeder with a spiral structure, one or more than one reaction cabin segments, and a programmable logic control apparatus, wherein the electric feeder comprises a motor and a feeding hopper with a spiral structure, the reaction cabin segment comprises a material reaction container with a spiral structure and a heating device placed in a hear source channel in the center of the reaction container, the material reaction container comprises a tubular shaft and one or a plurality of metal integration containers enclosed by spiral blades along a tubular jacket, and the spiral blades are provided with plow-shaped fins, wherein the tubular shaft is molded through casting integration molding, and is provided with single-head spiral blades or multi-head spiral blades.

Description

technical field [0001] The invention relates to the technical field of industrial furnaces, in particular to an energy-saving reaction furnace with a non-integral hollow spiral structure that is easy to control reaction conditions. Background technique [0002] Medium and low-grade aluminum-silicon-magnesium series and other non-metallic minerals are important non-metallic mineral resources in my country. The use of natural quartz, medium and low-grade refractory bauxite and other silicon-containing aluminum-silicon-magnesium series minerals, tailings, and solid waste is large and cheap Non-metallic minerals and industrial solid wastes are used as raw materials, and the transformation of high-performance carbonitride composite refractory materials through carbothermal reduction, carbothermal reduction nitriding and other technologies can not only greatly reduce the production cost of high-performance carbonitrides, but also It can effectively increase the product added value o...
