APPARATUS AND METHOD FOR HIGH FLOW PARTICLE BLASTING WITHOUT PARTICLE STORAGE

摘要

A particle blast apparatus transport is capable of generating granular sized particles and delivering them without substantial storage to a single hose feeder assembly. The apparatus is configured to be used with solid blocks of cryogenic material, such as carbon dioxide, and with individual pellets of such material.

主权项

1. An apparatus for metering discrete particles of carbon dioxide, the apparatus comprising:
a. a storage bin configured to receive discrete particles therein, said storage bin comprising a first end; b. an internal passageway; c. a carrier interposed between said internal passageway and said first end of said storage bin, said carrier being moveable with respect to said storage bin, said carrier comprising a plurality of openings configured to pass said discrete particles therethrough from said storage bin to said internal passageway at a flow rate, at least one first opening of said plurality of openings having a size which is settable between and including a first size and a second size, the flow rate determined at least in part by the size of said at least one first opening of said plurality of openings; and d. a plate disposed to move within said storage bin, said plate configured to urge the discrete particles disposed within said storage bin against said carrier.
