Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a rotating sand separator component. 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 generally adopts fixed spray guns or swing spray guns and translation spray guns. The structure is complex and the working conditions are bad, which can easily cause damage to the transmission parts. The sand separator of the traditional spray gun structure is generally fixed on the equipment, resulting in the sand pipe and air pipe in the equipment being too long and messy, which are easily damaged by friction with the swing of the spray gun. In addition, the sandblasting efficiency is low, the sandblasting surface is prone to produce positive and negative surfaces, and the spray gun angle adjustment is cumbersome.

[0005] In view of this, we propose a rotating sand separator assembly. Utility Model Content
