A sulfur feeder

Abstract

The invention relates to a sulphur blanking device, in particular to a sulphur combustion blanking device. The sulphur combustion blanking device comprises a material crushing furnace and a feeding structure, wherein the feeding structure is positioned under the material crushing furnace and is communicated with the material crushing furnace; the material crushing furnace comprises a material crushing cavity arranged at the upper part and a material falling cavity positioned at the lower part of the material crushing furnace; material crushing slurry is contained arranged in the material crushing cavity; a material separation distributing structure is erected in the middle of the material falling cavity; the feeding structure comprises a feeding pipe and an air inlet pipe positioned underthe material feeding pipe; a spiral material conveyor is arranged in the feeding pipe; the tail end of the spiral material conveyor is connected with the air inlet pipe through the material falling pipe; the air inlet pipe is connected with an air compressor. The sulphur combustion blanking device has the advantages that the sulphur is sieved and is then combusted; the combustion is uniform and stable; the utilization rate is high; the spiral material conveyor is utilized for quantitively conveying the sulphur; the in cooperation with uniform air inlet quantity is matched; the gas enters the combustion furnace after uniform mixing, so that the combustion of the sulphur is sufficient; the obtained sulfur dioxide has stable concentration; the quality of subsequent products quality is improved.

Description

technical field [0001] The invention relates to a sulfur feeding device, in particular to a sulfur burning feeder. Background technique [0002] In the production process of sodium metabisulfite, sulfur combustion is required to produce sulfur dioxide. The existing sulfur is fed into the sulfur furnace by simple screw conveyors or conveyor belts. Some of the imported sulfur is in the form of granules, flakes, and lumps of sulfur. The sulfur particles are uneven, resulting in uneven combustion of sulfur in the combustion furnace. , Insufficient, so that the purity of the produced sulfur dioxide gas is reduced and the concentration is unstable, which in turn affects the production quality of sodium metabisulfite. Contents of the invention [0003] In view of the above problems, the present invention proposes a feeder for burning sulfur, which cuts the sulfur evenly, and then uniformly mixes the air and enters the combustion furnace for combustion, so that the obtained sulfu...
