[0001] The present invention relates to a dry ice blasting device using dry ice particles as blasting material. Background technique
[0002] An example of a schematic configuration of a conventional dry ice blasting device is shown in FIG. 6 . The structure of this existing device is that, on the output port of the air compressor 90 of the medium-high pressure type that air is compressed to more than 8 atmospheres (atm), an air dryer 91, a pipeline 92 and a nozzle 93 are connected. The dry ice particles D stored in the hopper 94 are supplied by the supply device 95 into the pipeline 92 a branched from the pipeline 92 . The dry ice particles D sent into the pipeline 92 a are mixed with the air flow in the nozzle 93 .
[0003] When this structure is adopted, the high-speed air flow mixed with the dry ice particles D is sprayed out from the nozzle 93, and the dry ice particles D can be used as the blasting material for blasting treatment. When the dry ice pa...
