Problems solved by technology

In this way, the dry ice particle D is crushed, or its wear amount is large, causing so-called waste
[0008] Fourth, because the air compressor 90 is a medium and high pressure type, and the price of the air compressor 90 itself is high, the price of the equipment attached to the compressor is also high
Therefore, it is more troublesome to operate

Embodiment Construction

[0032] Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

[0033] figure 1 An embodiment of the dry ice blasting apparatus of the present invention is shown. The dry ice blasting device A of this embodiment has a movable frame 1, an air compressor 2, a pipe body 30 connected to the output pipeline 20 of the air compressor 2, a hose 31, a nozzle 32, an operation part 4A, and a control part 4B. , hopper 5, rotary feeder 6 and door hammer 7.

[0034] The movable frame 1 is formed in an approximate box shape as a whole, and constitutes other components of the dry ice blasting device A, which are directly or indirectly installed on the movable frame 1 . The movable frame 1 has a plurality of wheels 10 and is easy to move on the ground. On the upper part of the movable frame 1, one or more handles 11 are installed.

[0035] The air compressor 2 is (for example) a Roots blower (Lu tsu ズロア), and the outlet pr...

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.

Description

technical field [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...
