Title:
DIFFERENTIAL PRESSURE-ELIMINATING BAG FOR INERT GAS CIRCULATION-TYPE BLASTING DEVICE, AND INERT GAS CIRCULATION-TYPE BLASTING DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/281763
Kind Code:
A1
Abstract:
[Problem] To provide: a differential pressure-eliminating bag that can be used to replace the gas inside of an inert gas circulation-type blasting device with an inert gas while being capable of maintaining a constant pressure inside of a cabinet of the device; and an inert gas circulation-type blasting device in which the differential pressure-eliminating bag is used. [Solution] This inert gas circulation-type blasting device circulates an inert gas inside of the device, wherein a differential pressure-eliminating bag is provided at a cabinet for projecting shot material onto an object to be machined, is provided at an outer side of the cabinet, and includes an internal space that communicates with the internal space of the cabinet. The differential pressure-eliminating bag is flexible or elastic so as to be capable of expansion and contraction according to pressure changes inside of the cabinet. The volume of the internal space is adjusted in accordance with the hermetic partial volume in the interior of the device including the cabinet.
