Description

Technical Field

[0001] The utility model relates to the technical field of steel shot production, in particular to a device for rounding microparticle steel shots. Background Art

[0002] Steel shot is an abrasive used in shot blasting machines, shot blasting equipment, shot peening machines, shot peening equipment, sandblasting machines, sandblasting equipment, steel pretreatment production lines, steel plate pretreatment production lines, and steel structure pretreatment production lines. At present, the shapes of stainless steel cut wire shots produced are different, and some have sharp corners. When such sharp-cornered steel shots are used, the sharp corners will reduce the surface finish and roughness of the workpiece, and even damage the surface of the workpiece, affecting the surface cleaning effect. Therefore, they need to be rounded and passivated.

[0003] For example, a high-efficiency stainless steel cut wire shot grinding and passivation device with patent number CN202121886134.X includes a processing box, which also includes a feed pipe, which is connected to the top of the processing box; in the utility model, the stainless steel cut wire shot is preliminarily broken up by a stirring rod, and is ground and passivated by a grinding ball, so that larger stainless steel cut wire shots are spirally fed again by spiral blades for rounding and passivation, thereby improving the rounding and passivation effect thereof, and smaller stainless steel cut wire shots are dispersed again by a dispersion plate after passing through the diversion effect of the diverter plate, and are screened and removed by the wind action of the fan blades, thereby further improving the quality of the stainless steel cut wire shots after the rounding and passivation treatment.

[0004] However, this structure has the following problems: first, there is only a rounding and passivation mechanism, and the rounding efficiency is low; second, the rounding and passivation mechanism is relatively simple, which easily leads to a large number of steel shots being filtered without being passivated.
