cautery device

Abstract

The invention relates to a burning device which comprises a combustion cylinder, a calcination cylinder, a discharging pipe, a solid-liquid separation cylinder and a discharging piece. A furnace chamber is formed in the calcination cylinder; the outer side of the calcination cylinder is sleeved with the combustion cylinder; an annular combustion chamber is formed between the combustion cylinder and the calcination cylinder; a feeding pipe and a plurality of burners are arranged on the combustion cylinder; the solid-liquid separation cylinder is arranged at the end of the discharging pipe; and the discharging piece is arranged on the solid-liquid separation cylinder. The discharging pipe comprises a solid joint part and a guiding part which are connected with each other, the solid joint part is connected to the calcination cylinder, the guiding part is arranged in an inclined mode relative to the solid joint part, and a discharging channel is formed in the discharging pipe. The burning device has the beneficial effects that excessive burning is avoided, the efficiency of heat conduction is high and calcined materials are conveniently guided out.

Description

technical field [0001] The invention relates to a cauterization device. Background technique [0002] A calciner is a piece of equipment used for high-temperature processing, such as in ironmaking, recycling rare metals, producing catalysts or calcining pellets. Calciners are generally used for processing small particle materials, for example, materials that are sensitive to oxidation, combustion, explosion and heat. The furnace body of the burning device is provided with a combustion chamber, and the particles to be calcined are accommodated in the annular combustion chamber and calcined in the annular combustion chamber. However, since the flame directly contacts and burns the particles in the annular combustion chamber, the particles around the flame are easily heated locally, resulting in excessive combustion of the particles. Moreover, due to the blocking of the particles adjacent to the flame, the remaining particles are heated unevenly, and the heat conduction effic...

AI Technical Summary

Problems solved by technology

However, since the flame directly contacts and burns the particles in the annular combustion chamber, it is easy to locally heat the particles around the flame, resulting in excessive combustion of the particles

Moreover, due to the blocking of the particles adjacent to the flame, the remaining particles are heated unevenly, and the heat conduction efficiency is not high.

In addition, it is difficult to export the calcined particles
