Abstract

The invention discloses a novel impeller head capable of improving input shot quality. The novel impeller head comprises a housing, a shot inlet pipe, a directional sleeve, blades, an impeller body and a spindle. The novel impeller head is characterized in that the shot inlet pipe comprises an internal shot inlet pipe and an external shot inlet pipe; the shot outlet of the internal shot inlet pipe is in butt joint with the shot blasting window of the directional sleeve; the diameter of the shot outlet of the straight section of the external shot inlet pipe is equal to that of the shot inlet of the internal shot inlet pipe; the shot outlet of the straight section of the external shot inlet pipe is in butt joint with the shot inlet of the internal shot inlet pipe; the curved section of the external shot inlet pipe is connected with the end of the shot outlet of the straight section, and extends and curves upwards; the air outlet end of a compressed air input pipe is connected with the joint of the straight section and the curved section of the external shot inlet pipe; the blades are shaped like cylindrical tubes; circular arc-shaped grooves are formed in the outer surfaces of the blades; the axes of the grooves are perpendicular that of the blades; a plurality of cylindrical near impeller fixed rods and a plurality of cylindrical far impeller fixed rods are arranged between two disks of the impeller body of the impeller head, and matched with the grooves in the blades; a thin part is arranged at the end part of a near impeller; an external conical surface is arranged at the end of the thin part; the external conical surfaces of two adjacent blades are closely butted. The impeller head has the advantages that less shot materials are used, abrasion to the blades is less, and the shot blasting quality is high.

Description

technical field [0001] The invention relates to a shot blaster. Background technique [0002] The surface cleaning of castings is one of the important processes in the casting production process. Cleaning includes removing the sticky sand on the surface of the casting and the core of the inner cavity, removing the riser, drape, burr and metal oxide scale formed by heat treatment. In the past 30 years, it has been expanded to strengthen the surface of the workpiece, improve the service life of the workpiece, remove rust, remove scale and sand and core of castings, etc. [0003] Shot blasting machine is the most important general-purpose basic equipment in workpiece surface cleaning machinery and equipment. It is widely used in metal surface treatment such as derusting, polishing, and sand cleaning in industries such as ships, automobile engineering, and machinery manufacturing. The domestic and foreign markets have huge demand. [0004] The shot blasting machine is the core...
