Sulphur feeder in sodium metabisulfite production

Abstract

The invention discloses a sulphur feeder in sodium metabisulfite production. The sulphur feeder comprises a bucket type shell body, a smashing structure, a filtering structure and an unloading structure, wherein the bucket type shell body is divided into an upper frame part and a lower funnel part; the smashing structure comprises a smasher and a supporting plate, a plurality of through holes areformed in the supporting plate, the supporting plate is provided with shielding sheets for adjusting the size of the through holes, the smasher comprises a motor arranged outside the top end of the upper frame part and a smashing rod which is connected with the motor and arranged in the upper frame part, and smashing blades are arranged on the smashing rod; the filtering structure is arranged under the smashing structure, and the filtering structure comprises an oscillating machine and a filter screen arranged in the upper frame part; the unloading structure comprises a circular-truncated-cone-shaped base and a size-adjustable unloading valve plate which is arranged between the upper end of the circular-truncated-cone-shaped base and a discharging opening, and a plurality of unloading channels are arranged between the upper end and the lower end of the circular-truncated-cone-shaped base. According to the sulphur feeder disclosed by the invention, the amount of sulphur powder enteringa combustion furnace is controllable, sulphur powder in the combustion furnace is promoted to be completely combusted, and energy consumption in the combustion furnace is saved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a sulfur adder in the production of sodium pyrosulfite. 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. [0003] Some existing sulfur conveying equipment, such as the Chinese invention patent with application number 201710306535.5, discloses a sulfur conveying and burning device, including a combustion furnace, a screw c...

AI Technical Summary

Problems solved by technology

The amount of sulfur entering the sulfur powder channel in this design is not fixed, because the amount of sulfur entering the combustion furnace is different every moment, so it is difficult to control the amount of oxygen entering, which may cause insufficient combustion of sulfur or waste energy
