A kind of antimony trioxide powder crystallization system

Abstract

The invention provides an antimonous oxide powder crystallization system. The antimonous oxide powder crystallization system comprises an antimony white furnace, a reactor, a crystallizer and a powdercollector, wherein the antimony white furnace is provided with an air hose and a feeding opening, a frequency conversion adjustable draught fan is arranged between the reactor and the crystallizer, the crystallizer and the powder collector are connected in a sleeving way and are fixed by using a regulating mechanism, and a low temperature air hose is arranged on the crystallizer. The length of the crystallizer is adjustable, the dwell time of an antimonous oxide material in a crystallization forming section is convenient to control, the crystal form and the grain size of an antimonous oxide power are further controlled, the product specifications of the antimonous oxide are guaranteed to be flexibly regulated on the same production line, the conversion of the crystal form is complete, theproduct quality is further controlled, the low-efficiency investment is avoided, the equipment production line is prevented from being left unused and being wasted, the difficulty in fund flow of theindustry is avoided, and due to the two-section air cooling mode, the whole system reaches rapid quenching, and the product index stably reaches the standard.

Description

technical field [0001] The invention belongs to the field of antimony trioxide preparation, and in particular relates to a crystallization system of antimony trioxide powder. Background technique [0002] Industrial antimony oxide production has a long history, mainly antimony trioxide, which is used in enamel, pigment, paint, plastic, glass, ceramics, papermaking, flame retardant and other industries, and can also be used as a catalyst. [0003] In the process of producing antimony trioxide powder in the existing industry, there are problems such as small cooling temperature gradient, complex crystal types, unstable whiteness, and uncontrollable particle size. Moreover, the specification structure of traditional production equipment cannot be adjusted. One production line can only produce one type of product. The adjustment of product specifications requires the construction of different production lines, which cannot flexibly respond to market demand, resulting in a large ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the object of the present invention is to provide a crystallization system of antimony trioxide powder, which can solve the problem that the production line of antimony trioxide cannot meet the production requirements of products of different specifications and the small cooling temperature gradient and the variety of crystal forms in the production process. Problems of complexity, unstable whiteness, and non-adjustable control of particle size
