Abstract

The present invention relates to a centrifugal abrasive grain projectile device centrifugally projecting the abrasive grains through the rotation of an impeller, wherein the impeller is constructed by multiple impeller blades being attached radially at prescribed intervals between a facing pair of disk-shaped side plates, the impeller is attached to a hub fitted on the output shaft of an electricmotor, the impeller is enclosed by an impeller cover, and abrasive particles are shot centrifugally as the impeller is rotated. A side liner (3) having a U-shaped cross-section, which overall forms an upside-down widening U-shape and is split into two sections at the top part, and that is used to protect the side wall of the impeller cover (2) from the abrasive grains which are shot by the impeller (1), is attached to and can be detached from the inside of the impeller cover (2). The impeller (1) is fastened to the hub (4) by screwing a bolt (15), which is inserted from the inside of a side plate (11), into the hub (4). The outer diameter of the impeller (1) is a maximum of 200 mm.

Description

technical field [0001] The present invention relates to an abrasive particle centrifugal projection device. More specifically, it relates to an abrasive particle centrifugal projection device in which a pair of disk-shaped side plates facing each other with a desired interval are spaced radially apart from each other. A plurality of impeller blades are attached to form an impeller, and the impeller is mounted on a hub fitted to the output shaft of the motor. The impeller is surrounded by an impeller cover, and abrasive grains are centrifugally projected by the rotation of the impeller. Background technique [0002] Conventionally, as one of such devices, there is a device disclosed in Japanese Patent No. 4085353 . In this device, the impeller cover is protected by a plurality of divided gaskets, and the impeller cover surrounds the impeller composed of the first and second two impeller side plates and a plurality of impeller blades and mounted on the front end of the rotatin...
