Description

Technical Field

[0001] The utility model relates to the field of shot blasting equipment, in particular to a shot blasting device for removing scale on the surface of steel. Background Art

[0002] After steel is forged, an oxide layer will form on its surface. In order to improve the surface quality of the steel, it is necessary to remove the scale on the surface of the steel. A common way to remove the scale is to use a shot blasting device for cleaning. The principle of the shot blasting process is to use high-speed jetting of steel castings or iron castings to remove the scale on the surface of the steel. After the cleaning, these shot blasts are mixed with the broken scale. During the process of recycling the shot blasts, it is necessary to remove the scale debris among them. The existing treatment method is to screen the recycled shot blasts and scale with a vibrating screen, and the process is cumbersome. Therefore, it is particularly necessary to develop a shot blasting device for removing scale on the surface of steel that can screen out the scale mixed in the shot blasts. Summary of the Invention

The support roller assembly 2 is used to support the steel. The shot peening pipes 4 are evenly distributed around the steel. A screening bin 5 is rotatably arranged below the power assembly 6. The power assembly 6 is prior art and will not be elaborated here;

[0016] The power assembly 6 is provided with a steel wire hose 7 inserted into the screening bin 5. A reciprocating rotation mechanism connected to the screening bin 5 is arranged at the lower end of the power assembly 6. The reciprocating rotation mechanism drives the screening bin 5 to reciprocate and rotate by 60 degrees. The power assembly 6 is provided with a delivery hose 10 connected to the shot peening pipe 4.

The end of the blanking pipe 11 is connected with a hose 14 connected to the screening bin 5. A collection tray 15 is arranged below the power assembly 6. The blanking pipe 11 conveys the mixture of shot peening and the scale broken by shot peening to the screening bin 5. The reciprocating rotation mechanism drives the screening bin 5 to reciprocate and rotate, so as to screen the shot peening and the scale, so that the scale fragments fall from the screening bin 5 and into the collection tray 15.

[0018] Embodiment 2: A shot blasting device for removing mill scale on the surface of steel, including a power assembly 6 and a shot blasting chamber 1.
