Shot blasting cleaning device

Abstract

The invention discloses a shot blasting cleaning device. The shot blasting cleaning device comprises a shell and an impellor stored in the shell. One end cover of the shell guides in a main shaft coaxially assembled with the impellor, the other end cover guides in a shot inlet pipe, the impellor is provided with an impellor cavity with the same axial line with the impellor, and assembly holes areevenly formed in the circumference of the impellor, wherein the assembly holes are straight penetrating round holes in the wall face of the impellor. Blades are pipe pieces, the blades are inlaid intothe assembly holes, and connected with the assembly holes through detachable connection structures, and the detachable connection structures are further used for adjusting the rotating angles of theblades around the axial lines of the blades. A jet pipe is provided, one end of the jet pipe is connected with the shot inlet pipe, and the other end of the jet pipe faces to the wall face of the impellor cavity in a plane where the axial line of the main shaft is treated as the normal line. The shot blasting cleaning device can effectively prolong the service life of the blades, and has good maintainability.

Description

technical field [0001] The invention relates to a shot blasting cleaning device. Background technique [0002] The traditional shot blasting technology is that the projectiles from the shot blasting tube are initially accelerated by the shot-separating wheel, thrown out through the directional sleeve set outside the shot-separating wheel, and then accepted by the blade, and continue to accelerate through the centrifugal force along the surface of the blade to fly out. Shot blasting device, so as to realize the shot blasting and strengthening of the surface of various parts. [0003] Since shot blasting is not limited by the size, shape and weight of the cleaned parts, it can improve the fatigue resistance of mechanical products and metal components and eliminate stress concentration. The elimination of stress concentration requires a relatively large mechanical impact, so the speed of the projectile impacting the surface of the part is required to be very fast. In addition...

[0007] Chinese patent document CN106425886A discloses a shot blaster with Y-shaped blades. The Y-shaped blades have two working surfaces. Compared with traditional arc-shaped blades, there is one more working surface, which is equivalent to doubling the service life, but Its improvement is still limited, and it still has more wearing parts, such as shot wheel and orientation sleeve, and the overall maintainability is limited
