WET TYPE BLAST INJECTION NOZZLE

摘要

PROBLEM TO BE SOLVED: To provide a new wet type blast injection nozzle capable of bringing uniform processing effect by uniformly dispersing abrasive material in slurry. SOLUTION: This blast injection nozzle has a nozzle body 1 which has a slurry chamber 8 formed longitudinally and small-diameter slurry inflow ports 9, 10 formed laterally staggered in relation to the longitudinal axis so as to form a swirling flow of slurry; a flat nozzle body 2 which has a narrow rectangular injection nozzle 20 parallel with the slurry chamber 8 and a tapered introduction part 21 formed at the top end, and is attached to the lower part of the nozzle body 1 so as to communicate with the slurry chamber 8; and an air nozzle body 4 which has an air nozzle line at the tip, where small-diameter air nozzles 30 for injecting high-pressure air are arranged in line, and an air intake groove 32 and introduces high-pressure air through the sides of the air intake groove 32.
