Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

[0029] refer to figure 1 , the antimony trioxide powder crystal collection tube includes a crystallization tube 1 , an annular collection chamber 10 arranged outside the crystallization tube 1 , and a connecting flange 2 located at the feed port of the crystallization tube 1 . The collection chamber 10 is communicated with the inner space of the crystallization tube 1 through the discharge port, and the antimony trioxide furnace gas enters the crystallization tube 1 to crystallize to form antimony trioxide crystals, which are collected in the collection chamber 10 . The connection flange 2 is used for the connection of the crystallization t...

Abstract

The invention discloses a crystallization collection tube for antimony trioxide powder, which comprises a crystallization tube, an annular collection chamber provided outside the crystallization tube, and a connecting flange located at the feeding port of the crystallization tube. The inside of the crystallization tube is composed of A partition, a support ring, a swing assembly, a movable crystal cover and a control rod are arranged from bottom to top. The antimony trioxide powder crystal collection tube in the present invention is specially used for the crystal collection of antimony trioxide, and the movable crystal cover obtains three The furnace gas with saturated concentration of antimony oxide is then crystallized, and two different swirls, inner and outer, are formed inside the movable crystallization hood, and a quenching environment is formed inside the movable crystallization hood. Both can produce gains, and the crystallization effect is good.

Description

technical field [0001] The invention relates to the technical field of antimony trioxide production equipment, in particular to an antimony trioxide powder crystal collection tube. Background technique [0002] Antimony trioxide is used in enamel, pigment, paint, plastic, glass, ceramics, papermaking, flame retardant and other industries, and can also be used as a catalyst. In the process of using metal antimony to prepare industrial antimony trioxide powder, it is necessary to crystallize the antimony trioxide furnace gas. During the crystallization of antimony trioxide furnace gas, the furnace is directly connected to the crystallization tube, and the heat of the furnace affects the crystallization reaction. Since the temperature is not quenched, the cubic crystal antimony trioxide will be mixed with orthorhombic crystal antimony trioxide, resulting in three The antimony oxide powder has complex crystal types, unstable whiteness, and unstable furnace gas saturation during...
