Abstract
A dry-ice blast device (A) includes an air compressor (2) of a low pressure type as a source of the compressed air, the delivery pressure being 1.2-2.5 atm. Dry-ice particle feeder (5), (6) is provided for mixing dry-ice particles (D) into the air flow in the air flow path upstream from a nozzle (32). This enables low pressure blasting, which suppresses the abrasion of the dry-ice particles (D), decreases the noise, reduces the overall size and weight of the device and makes easy the handling of the device.
Claims13
A dry-ice blast device comprising:
- an air compressor;
- an air flow path for guiding an air flow generated by the air compressor to a nozzle;
- and a dry-ice particle feeder for supplying dry-ice particles into the air flow;
- wherein the air compressor is of a low pressure type having a delivery pressure of 1.2-2.5 atm;
- and
- wherein the dry-ice particle feeder supplies the dry-ice particles into the air flow at a position upstream along the air flow path from the nozzle.
