A bottom slag smelting device for reduced crude magnesium

Abstract

The invention discloses a smelting device capable of discharging slag from the bottom and restoring crude magnesium. The device includes a combustion chamber, and a first clapboard and a second clapboard are clamped in the combustion chamber; the first clapboard and the second clapboard divide the combustion chamber into a first cavity, a second cavity and a third cavity, and a conveying opening is formed in the center of the first clapboard; first valves are arranged on both ends of the conveying opening, each first valve is installed on the first clapboard, a collecting device is arranged onthe first cavity, the second cavity is internally provided with a catalyzing device and a heating device, and a second valve is arranged on the second clapboard. The device has the advantages that the structure is simple, the operation is easy, and through interaction of the catalyzing device, the heating device and other structures, raw materials can be blended, a more complete reaction can be carried out, and the reaction rate is increased; through interaction of a smashing device and other structures, waste slag with excessively large particles can be smashed, and therefore pipelines can be prevented from being blocked during transportation.

Description

technical field [0001] The invention relates to the technical field of magnesium smelting, in particular to a bottom slag smelting device for reducing coarse magnesium. Background technique [0002] In 1808, British Davy used potassium to reduce magnesium oxide to obtain metallic magnesium. It is a silver-white light alkaline earth metal with active chemical properties, which can react with acid to generate hydrogen gas, and has certain ductility and heat dissipation. Magnesium is widely distributed in nature and is one of the essential elements for the human body. [0003] After searching, the patent No. is CN 104630506 A, which discloses a smelting device for reducing coarse magnesium bottom slag, including a furnace, and a reduction tank is vertically arranged in the furnace, and the reduction tank is located between the upper top and the lower top of the furnace. The upper top of the hearth is arched, the side of the hearth is provided with three or more burners, the b...

Problems solved by technology

[0007] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, as: the reaction in the hearth, is to make it react slowly by adding raw material in the hearth and then heating, but such mode reaction rate is slow, makes the raw material simultaneously Accumulation easily leads to insufficient reaction;
