Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a novel rotating sand separation device. Background Art

[0002] Sandblasting machine is a machine that uses compressed air as power to form a high-speed jet beam to spray the material at high speed onto the surface of the workpiece to be processed, so that the mechanical properties of the outer surface of the workpiece surface change. The working principle of sandblasting is to use compressed air as power to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, sea sand, etc.) at high speed onto the surface of the workpiece to be processed, so that the appearance or shape of the workpiece surface changes.

[0003] Due to the impact and cutting action of the abrasive on the workpiece surface, the workpiece surface obtains a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating. Sandblasting can also remove rust. Sandblasting is mainly a high-speed jet method formed by the principle of air compression as the power. Sandblasting materials can be divided into several types, namely garnet sand, quartz sand, copper ore sand, iron sand, corundum, etc. This kind of sandblasting used on the surface of the workpiece can help remove rust and effectively improve its surface.

[0004] Traditional automatic sandblasting equipment mainly fixes the sandblasting gun directly or detachably installs it in the equipment compartment through bolts, and then installs the workpiece on a rotatable fixture. When in use, the rotatable fixture drives the workpiece to rotate, and the sandblasting gun sandblasts the rotating workpiece. Although the sandblasting gun of some equipment is detachably connected by bolts, it can only adjust the sandblasting angle and cannot perform sandblasting operations on products of different heights. In view of this, we propose a new type of rotating sand separation device. Utility Model Content
