Blade, impeller structure and impeller fastening type spraying machine

Abstract

The the invention provides a blade, an impeller structure and an impeller fastening type spraying machine. A blade body of the blade comprises a firs tend face, a second end face, a third end face anda fourth end face, wherein the first end face is connected with the second end face in a parallel manner; the third end face and the fourth end face are oppositely arranged and respectively form intoinclined planes relative to the first end face and the second end face; receiving and throwing grooves communicating with the first end face and the second end face are formed in the third end face and the fourth end face correspondingly; the shape of the first end face is the same as that of the second end face; the sectional area of the second end face is larger than that of the first end face;a fifth end face and a sixth end face are respectively connected with the first end face and the second end face; and at least one protruding body is arranged on the fifth end face and the sixth endface. According to the blade, the impeller structure and the impeller fastening type spraying machine, the whole blade body is formed into a wedge-shaped structure, and the blade body is connected with a turntable more tightly when rotates, so that the connection stability of the blade and the turntable is guaranteed, and the rotation speed which can be borne by the blade and the whole impeller isincreased; and meanwhile, the connection stability is further improved due to the fact that the protruding body is arranged.

Description

Technical field [0001] The invention relates to the technical field of sandblasting, in particular to a blade, an impeller structure and an impeller tight-locking type spraying machine. Background technique [0002] Sandblasting is a destructive processing method for the surface of the material. It uses fine abrasive sand particles to impact the surface of the material, causing the surface of the material to produce granular depressions to form a matte or corroded surface to achieve gold removal Rust, deoxidation, beautification, fogging, matting and other purposes, and can improve the surface finish of the material, so it is widely used. [0003] In order to achieve the above purpose, the impact speed and force of the sand particles on the surface of the material are very important. Generally speaking, a blade runner structure is used to project sand materials. However, the traditional blade runner structure has a limited speed and cannot obtain a full-scale finish on the surface...
