Title:
NOZZLE ASSEMBLY AND SURFACE TREATMENT METHOD USING SAID NOZZLE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2016/136443
Kind Code:
A1
Abstract:
The present invention provides a nozzle assembly for ejecting an ejection material mixed with compressed air, thereby treating the surface of an object to be treated. This nozzle assembly has: a nozzle body provided with an ejection material suction opening for sucking in an ejection material and with an ejection opening for ejecting the ejection material together with compressed air; and an air nozzle for ejecting the compressed air into the nozzle body. The nozzle body has: a mixing chamber having formed therein a space for mixing the ejection material, which is sucked in through the ejection material suction opening, with the compressed air; a first passage which is a passage leading from the ejection material suction opening toward the mixing chamber; and a second passage which is a passage leading from the mixing chamber toward the ejection opening. The air nozzle is provided with: a compressed air ejection section formed at the front end of the air nozzle; and a third passage which is a passage leading toward the compressed air ejection section. The third passage is inserted in the nozzle body so that the compressed air ejection section is located in the mixing chamber of the nozzle body. The compressed air ejection section of the air nozzle is provided with a flow constriction section having an opening having a cross-section smaller than that of the third passage.
