Slurry device and production equipment of nanometer metal oxide powder including the same

Abstract

The invention relates to a slurrying device and nano metal oxide powder production equipment comprising the slurrying device. The slurrying device is used for slurrying colloid. The slurrying device is characterized in that a feeding hole is formed above the slurrying device; the slurrying device comprises a mixing drum and a slurrying tank; the mixing drum comprises a stirrer and a plurality of crushing devices; the stirrer comprises a stirring shaft and a plurality of stirring paddles; the plurality of stirring paddles are arranged on the stirring shaft along the axial direction; one crushing device is arranged between each two stirring paddles; the crushing devices pass through the stirring shaft and are fixedly connected with the inner wall of the slurriyng device; the slurrying tank is communicated with the mixing drum and is arranged below the mixing drum; a plurality of groups of screw rods are arranged inside the slurrying tank, and are used for further extruding and crushing materials; and a plurality of holes are formed in the wall of the slurrying tank to be used for outside flowing of the slurry. Rapid drying of the colloid can be achieved by adopting the slurrying device, oxygen is introduced via air holes which are evenly distributed in a high-temperature region of a combustion chamber, and the material can fully react and combust in the combustion chamber, so that the energy consumption is reduced, meanwhile, the washing and suction filtration links of the colloid are eliminated, and the prepared nano metal oxide powder is excellent in performance.

Description

technical field [0001] The invention relates to the field of nano-powder material equipment, in particular to a slurryer for colloid slurry and production equipment for nano-metal oxide powder. Background technique [0002] Nano metal oxide powder material is a very active research field in solid state physics, materials chemistry and biomedicine. The particle size of nanopowder is ultrafine particles on the nanometer scale (1-100nm). When the size of the powder particle enters the nanometer scale, it will produce quantum size effect, interface effect, small size effect and macroscopic quantum effect. Therefore, nanometer metal oxide powder materials have broad application prospects in chemical catalysis, electronic ceramics, biomedicine, magnetism and other fields. [0003] With the continuous deepening of research on nanoparticles and nanomaterials, there are more and more new methods for preparing nanometer metal oxide powder materials, which can be summarized into three...
