Abstract
A particle blast cleaning apparatus for use with sublimable blast media, a source of compressed gas, and a discharge nozzle. The apparatus includes a mixing device for mixing the sublimable media with compressed gas, which mixing device includes a lower section having an outlet port formed therein and an upper section positioned over the lower section and having two sublimable media inlet ports and a compressed gas inlet port. A transfer member is mounted between the lower section and the upper section for reciprocal movement and has at least two transfer chambers for transporting sublimable media.
Claims19
A particle blast cleaning apparatus for use with sublimable blast media, a source of compressed gas, and a discharge nozzle, said apparatus comprising:
- mixing means for mixing sublimable media with compressed gas, said mixing means including:
- a lower section having an outlet port formed therein;
- an upper section positioned over and spaced apart from said lower section and having two sublimable media inlet ports and a compressed gas inlet port aligned with said outlet port of said lower section and positioned between said sublimable media inlet ports;
- and
- a reciprocating transfer member slidably mounted between a first bearing strip attached to said upper section and a second beating strip attached to said lower section for reciprocal movement, and having at least two transfer chambers for receiving sublimable media from said sublimable media inlet ports and for transporting the sublimable media to adjacent said outlet port.
