Automatic classified collection device for nanopowder

Abstract

The invention discloses an automatic classified collection device for a nanopowder. The automatic classified collection device comprises a support frame and a plurality of collection units, wherein the support frame comprises an upper support plate and a lower support plate; the collection unit comprises a collection barrel, a powder scraping brush and collection grooves; the both ends of the collection barrel are clamped on the support frame via limit holes in the upper support plate and the lower support plate of the support frame respectively; a gear is arranged at the top end of the collection barrel and connected with a motor via a chain; the powder scraping brush and the plurality of collection grooves are clung to the outer wall of the collection barrel; the both ends of the powder scraping brush are fixed on the upper support plate and the lower support plate of the support frame respectively; and the collection grooves are fixed on the powder scraping brush. According to the invention, the problem of cooling effect reduction of the collection barrel due to deposition thickness increment of nanoparticles of the conventional device is solved; the collection grooves are arranged at different heights, thus realizing separate collection for the nanoparticles deposited at different heights; and the device can realize continuous production for the nanopowder.

Description

technical field [0001] The invention specifically relates to a nano powder automatic collection device. Background technique [0002] figure 1 It is a common metal nano powder production device. In the vacuum chamber, the metal source is under the action of plasma bombardment, laser irradiation or electric heating, and the metal atoms are separated from the metal source body, and these metal atoms will be sputtered around the reaction chamber. , and finally meet the cold deposition on the collection barrel to form nanoparticles. The size of these nanoparticles is related to the distance between the collection barrel and the metal evaporation source and the temperature of the wall of the collection barrel. The collection barrel of the device is fixed. When the device is used to produce nano-powder, as the nano-powder deposited on the inner wall of the collection barrel gradually increases, it is difficult to ensure the cooling effect of the collection wall on the nano-powder...
