Problems solved by technology

The present invention has simple structure and low production cost. The preparation of antimony trioxide by using the present invention only needs compressed air instead of pure oxygen. Although the invention discloses a catalyst-grade antimony trioxide preparation device, with the advancement of science and technology progress, the purity of the antimony trioxide produced by it still cannot meet the needs of market progress

Embodiment 1

[0028] like Figure 1-2 As shown, the nanoscale antimony trioxide preparation device of the invention includes an antimony white furnace 1 and a crystallizer 11. The antimony white furnace 1 is provided with a connected front chamber 2, middle chamber 3 and breech chamber 4, and the top position of the front chamber 2 is , the upper position of the metal antimony liquid a is provided with a rotary blower 5, and the rotary blower 5 is installed on the top of the front chamber 2 through a rotating part, such as a rotating rod. On the outer surface of the blower, its wind source and power come from the exhaust fan (not shown in the figure).

[0029] Bottom blowpipe 7 and top blowpipe 6 are arranged at middle chamber 3, and bottom blowpipe 6 extends into metal antimony liquid a, and top blowpipe 6 passes antimony white furnace 1 and extends into the surface of metal antimony liquid a,

[0030] A reactor 10 is connected to the top of the breech 4 , and a crystallizer 11 is arrange...

Embodiment 2

[0034] In the present embodiment, the blast volume 5 of the rotary blower is 210 3 / h, the blowing volume of the blowing pipe 7 at the bottom is 0.5MPa, and the flow rate is 260m 3 / h, all the other working principles are the same as in Example 1.

Abstract

The invention discloses a device for preparing nanoscale antimony trioxide. The device comprises an antimony white furnace and a reactor and is characterized in that a front chamber, a middle chamber and a rear chamber communicated with one another are arranged in an inner chamber of the antimony white furnace, a rotary air blower is arranged at the top of the front chamber, a bottom blowpipe and a top blowpipe are arranged in the middle chamber, the bottom blowpipe extends into antimony liquid, the top of the rear chamber is connected to the reactor, and a double-layer crystallizer is arranged at the top of the reactor.

Description

technical field [0001] The invention relates to a device method for antimony trioxide, in particular to a nanoscale preparation device for antimony trioxide. Background technique [0002] The preparation of nanoscale antimony trioxide is an important raw material in chemical production. As a flame retardant in chemical reaction, it is required that the antimony trioxide not only has high purity, but also does not contain high-priced antimony tetroxide. It is required to have a high flame retardant effect. [0003] Among the existing antimony trioxide equipment, some devices for preparing antimony trioxide are disclosed, [0004] In recent years, some published documents have reported methods for preparing antimony trioxide, such as: [0005] 1. Chinese patent, application number: CN201210097320.4, application date: 2012.04.05 Name: catalyst-grade antimony trioxide preparation device, abstract: the invention discloses a catalyst-grade antimony trioxide preparation device, i...
