A staged combustion equipment for a suspension roaster

Abstract

The invention relates to the field of combustion of suspension roasting furnaces, in particular to suspension roasting furnace grading combustion equipment which comprises a separated dropping mechanism, a screening mechanism, a first combustion mechanism, a second combustion mechanism, a supporting mechanism, a drive mechanism and a linkage mechanism. For the suspension roasting furnace grading combustion equipment, the drive mechanism is matched with a first combustion mechanism in a furnace body to realize heating of larger materials, heating is more comprehensive as the first combustion mechanism is closer to the bottom of the furnace body, and the linkage mechanism is used for swinging the second combustion mechanism arranged in the furnace body while the first combustion mechanism moves in a reciprocating manner, so that stir-frying of materials in a stir-frying bucket in a fixed frame can be realized, and graded heating, comprehensive reaction and uniform stirring are realized;and the furnace body side wall mechanism is matched with the screening mechanism to be used for sorting coarse and fine materials needing to be heated, and the separated dropping mechanism enables thelarger materials to flow into a stir-frying pan and the stir-frying bucket from a coarse material hole and a fine material hole respectively for graded heating after sorting, so that the workload isreduced, and the time and the labor are saved.

Description

technical field [0001] The invention relates to the combustion field of a suspension roaster, in particular to a staged combustion equipment for a suspension roaster. Background technique [0002] Roasting is the process of completing a certain chemical reaction below the melting temperature of the material, which is an integral part of the charge preparation. Most of the materials always exist in solid state, so the upper limit of the roasting temperature is to ensure that the materials do not melt obviously, and the suspension combustion is to heat the materials without melting, so as to change their chemical composition or physical properties. The reaction process of solid materials under the condition of high temperature without melting, which can include oxidation, pyrolysis, reduction, halogenation, etc., is usually used in inorganic chemical and metallurgical industries. [0003] However, in the existing suspension roaster, the material is first screened when the mat...

Problems solved by technology

[0003] However, in the existing suspension roaster, the material is first screened when the material is graded and burned, and then poured into the interior of the designated combustion chamber to realize the graded combustion, and the material cannot be screened and automatically poured in when the material is loaded. Staged combustion in designated combustion chambers requires heavy workload, time-consuming and labor-intensive
