Title:
INJECTION NOZZLE FOR BLAST MACHINING
Document Type and Number:
WIPO Patent Application WO/2011/024613
Kind Code:
A1
Abstract:
Provided is a highly durable injection nozzle for blast machining, which is capable of machining a wide width area uniformly. The nozzle (10) is provided with a gas injection portion (11), a supply port (12) for supplying an injection material, a mixing chamber (13) which is connected to the gas injection portion and the supply port and in which a compressed gas supplied from the gas injection portion and the injection material supplied from the supply port are mixed to form a solid-gas two-phase flow, and an injection material injection portion (14) which injects the solid-gas two-phase flow introduced from the mixing chamber onto an object to be machined. A flow regulator (20) which widens a flow of the compressed gas in the major side direction is formed at an opening (11b) of the gas injection portion. The flow regulator is provided with flow regulation members (21) having flow regulation surfaces (21a) for widening the flow of the compressed gas in the major side direction of a rectangular section of the gas injection portion. The flow regulation members (21) are provided perpendicularly to the major sides and symmetrically with respect to a center line of the major sides and divide a first passage (11a).
