Gallium oxide fine grinding and screening device

Abstract

A gallium oxide fine grinding and screening device comprises a calcining tank. An electric heating plate is arranged in the calcining tank, the upper part of the calcining tank communicates with a rawmaterial inlet pipe, a rotating motor is arranged above the top of the calcining tank, an output shaft of the rotating motor is fixedly connected with the top end of a rotating shaft, the rotating shaft penetrates through the central position of the top of the calcining tank, a first bearing is arranged between the rotating shaft and the top of the calcining tank, a second bearing is arranged between the bottom end of the rotating shaft and the bottom in the calcining tank, a stirring blade is arranged on the rotating shaft, the bottom of the calcining tank communicates with a discharging pipe, an electromagnetic valve is arranged on the discharging pipe, the discharging pipe communicates with a crushing feeding pump, the feeding pump communicates with a crusher, the crusher communicateswith a crushing discharging pump through a pipeline, the crushing discharging pump communicates a screener, and a screening device is arranged in the screener. Powder materials can be effectively prevented from being hardened in the calcining process, the crushed gallium oxide powder can be automatically screened and recycled according to the particle size, and the gallium oxide products with different particle sizes can be conveniently provided for customers with different requirements.

Description

technical field [0001] The invention belongs to the field of gallium oxide production, in particular to a fine grinding and screening device for gallium oxide. Background technique [0002] Gallium oxide, or gallium trioxide, is the most stable of gallium oxides. Heating metal gallium in air to oxidize it, or converting and dehydrating gallium hydroxide at 200-250°C can form gallium oxide. Since the last step in the production of gallium oxide is to calcinate gallium metal salts, since it is generally calcined at high temperature, and to obtain β-Ga 2 o 3 The crystal form of gallium oxide generally needs to be heated above 500°C to realize it. Gallium oxide is easy to harden during high-temperature calcination, so it is not convenient to discharge when discharging, and at the same time, large pieces of hardened material are not convenient for pipeline transportation and crushing , At the same time, because the manufacturers have different requirements for the particle siz...

Since the last step in the production of gallium oxide is to calcinate gallium metal salts, since it is generally calcined at high temperature, and to obtain β-Ga 2 o 3 The crystal form of gallium oxide generally needs to be heated above 500°C to realize it. Gallium oxide is easy to harden during high-temperature calcination, so it is not convenient to discharge when discharging, and at the same time, large pieces of hardened material are not convenient for pipeline transportation and crushing At the same time, because the manufacturer has different requirements for the particle size of the product, the current gallium oxide product powder is collected directly after crushing, lacking a screening device
