Abstract

The invention provides a spray gun for wet blasting capable of inhibiting making openings in the spray gun main body with a slurry flowing-in chamber. The spary gun (10) comprises a main body (11), a gas ejection part (12), and a nozzle unit (13). A slurry flowing-in chamber (20) is formed in the main body (11). The gas ejection part (12) comprises a gas ejection hole (53) and a gas flowing portion (55) connected thereto. The nozzle unit (13) comprises a nozzle part (14) composed of a superhard alloy. The nozzle part (14) comprises a flange part (70) and a cylinder part (71). An ejection flowing part (72) and a slurry ejection port (82) communicating therewith are formed in the cylinder part (71). A concave part (75) with a continuous erected wall (76) in the circumferential direction is formed in a first surface (70a) of the flange part (70). A slurry guiding hole (80) is formed at the center of the bottom (75a) of the concave part. The flange part (70) is fastened to the main body (11) by a fastening mechanism (15) including clamping members (91, 92) and bolts (93, 94).

Description

technical field [0001] The present invention relates to a spray gun for wet blast (blast), which sprays a slurry containing an abrasive in a liquid onto a work (target). Background technique [0002] One of the sandblasting devices used for the surface treatment of workpieces is known, for example, as described in Patent Documents 1 and 2, by spraying slurry containing abrasives in the liquid to the workpiece to perform surface treatment of the workpiece. Sand blasting device. A spray gun used in a wet blasting device includes: a gun body having a slurry inflow chamber; an air jet part for spraying air; a nozzle part for spraying slurry together with the sprayed gas; and the like. Wet blasting is also known as horning. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2008-132542 [0004] Patent Document 2: Japanese Unexamined Patent Publication No. 2012-228743 [0005] It is known that a component that flows at high speed together with a slurry and ...
