Multi-functional upper expanding device for producing antimony trioxide

Abstract

A multi-functional upper expanding device for producing antimony trioxide comprises an inlet pipe, an abdomen pipe, and an air exhausting pipe, wherein the inlet pipe, the abdomen pipe and the air exhausting pipe are orderly connected and communicate with each other; the inner diameter of the abdomen pipe is larger than those of the inlet pipe and the air exhausting pipe; the inlet end of the inlet pipe is arranged on the outlet end of the antimony trioxide reaction chamber, and the outlet end of the air exhausting pipe is connected to the inlet end of the antimony trioxide crystallization device. The multi-functional upper expanding device can adjust the particle size of antimony trioxide product at will, effectively controls the antimony trioxide product quality, timely recycles the agglomerated oxides generated during the antimony trioxide production process, and improves economic and technical indexes such as product yield, and the like.

Description

technical field [0001] The invention relates to a multifunctional up-extender for producing antimony trioxide. Background technique [0002] In the traditional smelting reverberatory furnace process, antimony ingot raw materials are oxidized in the reaction chamber and then directly enter the dust collection system. The control of product particle size can only depend on the cooling air volume provided by the dust collection system. On the one hand, a large amount of antimony oxide is collected at the outlet. The impact of different air volumes is easy to form agglomerates, resulting in a decrease in the main component of the product and an increase in the number of intermediate products; on the other hand, the outlet is blocked, cleaning is difficult, the output of the product is reduced, and the unit cost is increased. The particle size control of traditional antimony oxide is generally carried out by a classifier, which requires a large investment in equipment and a lengt...

[0002] In the traditional smelting reverberatory furnace process, antimony ingot raw materials are oxidized in the reaction chamber and then directly enter the dust collection system. The control of product particle size can only depend on the cooling air volume provided by the dust collection system. On the one hand, a large amount of antimony oxide is collected at the outlet. The impact of different air volumes is easy to form agglomerates, resulting in a decrease in the main components of the product and an increase in the number of intermediate products; on the other hand, the outlet is blocked, the cleaning work is difficult, the product output is reduced, and the unit cost is increased.

The particle size control of traditional antimony oxide is generally carried out by a classifier, which requires a large investment in equipment and a lengthy process flow. Instead of controlling the product particle size and other quality indicators from the source of the production process, it is artificially classified, which brings more trouble to the next product packaging process. high difficulty
