Description

Technical Field

[0001] This utility model relates to the field of sand separation technology, specifically a sand separation device for cleaning rare and precious metal turning materials. Background Technology

[0002] Rare and precious metals are often used to process key components of mechanical equipment due to their excellent properties. A large amount of turning material is generated during the machining process. Currently, the turning material is simply recycled and then devalued (metal materials containing vanadium, niobium, tungsten, cobalt and nickel are used to smelt ordinary steel). The rare and precious metals in them are not effectively utilized, which causes a great waste of resources.

[0003] In the process of processing precious metal turning waste, we use sand washing to effectively remove the oxide and acid layers attached to the surface of the waste. Given that the sand particles used in the sand washing process have high durability and recyclability, it is necessary to recover these sand particles from the washing solution to achieve resource recycling. When separating, attention should be paid to the unobstructedness of the screen. If the screen is blocked, it will affect the screening effect of the sand particles.

[0004] Therefore, a special sand separation device for cleaning rare and precious metal turning materials is proposed. Utility Model Content

[0018] 2) The second cylinder drives the adjusting block to move, which in turn drives the moving frame to adjust its height. The moving frame then drives the fixed seat to move, thereby changing the height of the left end of the separation hopper and causing the separation hopper to tilt. When the separation hopper tilts, the sand and precious metal machining waste are more easily distributed along the screen and fall under the action of gravity and vibration, which helps to improve the screening efficiency. At the same time, by adjusting the tilt angle, the residence time and movement trajectory of the sand on the screen can be controlled. Attached Figure Description
