Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0028] refer to figure 1 , the industrial antimony trioxide production device comprises a reaction furnace 1, a blowing pipe 3, a crystallization pipe 4 and a collection chamber 10, the feed port 2 of metal antimony is arranged on one side of the reaction furnace 1, and the blowing pipe 3 is used for feeding the reaction The interior of the furnace 1 is filled with air, so that the metal antimony reacts with oxygen in the reaction furnace 1 to generate antimony trioxide furnace gas, and the antimony trioxide furnace gas enters the crystallization tube 4 to crystallize to form antimony trioxide crystals, which are collected in the collection chamber 10 collect.

Abstract

The invention discloses an industrial antimony trioxide production device which comprises a reaction furnace, an air blowing pipe, a crystallization pipe and a collection chamber, a metal antimony feeding port is formed in one side of the reaction furnace, a rotation starting assembly, a movable crystallization cover and a control rod are arranged in the crystallization pipe from bottom to top, and the control rod is connected with the top of the movable crystallization cover and the top of the crystallization pipe. The antimony trioxide production device is used for producing antimony trioxide, furnace gas with saturated antimony trioxide concentration is obtained through the movable crystallization cover and then is crystallized, the crystallization efficiency can be effectively improved, crystal particles are kept uniform, and the stability of product quality is kept; and the crystallization efficiency and the lens particle uniformity are also improved by two different inner and outer rotational flows in the movable crystallization cover.

Description

technical field [0001] The invention relates to the technical field of antimony trioxide production equipment, in particular to an industrial antimony trioxide production device. 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. During the crystallization process of antimony trioxide powder, the furnace is directly connected with the crystallization tube, and the heat of the furnace affects the crystallization reaction. Since the temperature is not cooled rapidly, the cubic crystal antimony trioxide will be mixed with orthorhombic crystal antimony trioxide, resulting in three The crystal forms of antimony oxide powder are complex, the whiteness is unstable, and the particle size of antimony trioxide powder cannot be adjusted and controlled due to the unstable sa...
