Description

Technical Field

[0001] The utility model relates to the technical field of zincating sand separation, and more specifically to an automatic zincating sand separation device. Background Art

[0002] During the sherardizing process, the workpiece is immersed in sherardizing sand containing zinc powder. Heating causes the zinc powder to chemically react with the workpiece surface, forming a uniform zinc layer on the surface to provide corrosion protection. During this process, the unreacted zinc powder needs to be effectively separated and recovered from the sherardizing sand for reuse while reducing environmental pollution. This requires the use of a separation device.

[0003] Chinese patent application number CN201120026605.X discloses a cooling and separation device for a zinc-diffusion tank. The tank body and tank cover are sealed by copper bars. A shaft and a B shaft are fixed to each end of the tank body. Shafts A and B are fixed to each other with shaft sleeves supported on two support rollers and an oil tank. A thermocouple is placed in the center of shaft A. The end of shaft B is fixed with an A-shaft coupling connected to a B-shaft coupling fixed to a drive shaft. The drive shaft is supported on a bearing with a seat. The B-shaft coupling and the A-shaft coupling are connected by a plug plate. The tank body and tank cover are placed in a sealed box, and two material receiving troughs are placed at the bottom of the pit. During separation, the tank cover is replaced with a grate. When the drive shaft rotates, sand and zinc powder fall from the spaces in the grate into the material receiving trough.

It has a wide range of applications and can be widely used in industries such as aviation, metallurgy, petrochemicals, construction, tunnels, and highways. However, some existing automatic separation devices separate the zinc sand and the workpiece through a simple horizontal reciprocating screen.
