Endogenous heat type hemicontinuous reduction furnace for producing magnesium, calcium and strontium

Abstract

The invention relates to metal reduction equipment, in particular to internally-heating metal reduction equipment for magnesium, calcium and strontium, which solves the problems that the existing reduction equipment is externally-heating structure, the volume of the reduction pot is small, one-time capacity is little, discharging is not continuous, the labor intensity is large, the utilization ratio of the fuel is low, the yield is less and the like. The reduction equipment comprises a furnace body; a charging hopper is arranged above the furnace, a reduction bin is arranged in the furnace body; a vacuum extraction pipe is arranged above the reduction bin; an internally-heating pipe is arranged transversely by the reduction bin; the adjacent heating pipe has a gap for charging and reaction; two ends of the internally-heating pipe are respectively provided with a regenerative chamber; the regenerative chamber is internally filled with heat retainers which are communicated with a combustion-supporting air pipe and is internally inserted with a fuel core pipe which is connected with the fuel; an ignition hole is arranged by the heat retainers; and the middle section of the internally-heating pipe is a combustion chamber. The reduction equipment has simple structure, reasonable design, small construction area of the furnace body, low energy consumption, low production cost and high production efficiency and is applicable to large-scale mechanical production and has large promotion value.

Description

technical field [0001] The invention relates to metal reduction equipment, in particular to internal heat reduction equipment for metal magnesium, calcium and strontium. Background technique [0002] At present, the reduction process for industrial production of metal magnesium, calcium and strontium is basically the same, and the main equipment in the reduction process, namely the reduction furnace, is also roughly the same. The reduction furnace is a kiln-like horizontal structure built with refractory materials. It is directly built on the ground. The reduction tank is placed horizontally or vertically in the reduction furnace. Internal combustion, the heat is transferred to the material in the tank through the reduction tank for reduction reaction. When the reduction tank is placed horizontally, because the crystallization tank must be taken out and the slag removal and feeding operations are performed, there are problems such as long feeding and slag removal time, high...

Problems solved by technology

[0009] The present invention solves the problem that the existing calcium, magnesium and strontium reduction equipment has an external heating structure, the reduction tank is small in size, the primary capacity is small, and the reduction tank and the reduction furnace are independent split structures, resulting in discontinuous discharge, high labor intensity, To solve problems such as low fuel utilization rate, high production cost, and small output, an internal heating type reduction furnace for semi-continuous production of metal magnesium, calcium, and strontium is provided
