Apparatus for precisely dispensing small amounts of ultra-fine particles |
摘要 |
A dispensing apparatus for the dispensing of ultra-fine particles on a dry basis in a reproducible manner. The apparatus includes a first gas-solids suspension chamber having particle fluidization means adapted thereto, and a conduit adapted between the first gas-solids chamber and a second gas-solids chamber for communicating via at least one particle orifice particles between the chambers. A high velocity gas stream provides a pressure difference between the chambers whereby a low pressure zone is created within the conduit thereby drawing in particles from the first gas-solids suspension chamber into the second gas-solids suspension chamber via the conduit. The apparatus further includes a combination of a withdrawal feed and a solenoid valve to direct particles from the second gas-solids suspension chamber into a collection area. |
