Description

Alloy steel shot screening device for aluminum casting surface polishing treatment Technical Field The utility model relates to the technical field of steel shot screening, in particular to an alloy steel shot screening device for polishing the surface of an aluminum casting. Background In the metal surface treatment, casting cleaning and polishing processes, alloy steel shots are widely applied to shot blasting and strengthening treatment due to the high hardness, wear resistance and recycling characteristics of the alloy steel shots. The alloy steel shot can be gradually broken and worn out due to repeated impact in the use process, so that the grain size is uneven, the polishing effect and the equipment service life are affected, and qualified steel shot, broken grains and dust are separated by a screening device, so that the process stability and the material utilization rate are ensured. At present, a steel shot screening device commonly used in the industry mainly adopts a vibration screening mode. But the vibrating screen realizes the classification through motor drive screen high frequency vibration, and its structure is complicated relatively, easily leads to screen cloth deformation or jam because of steel shot impact, can not distinguish the steel shot that wearing and tearing are serious and the steel shot that can also continue to use completely, makes screening inefficiency to the separation effect to fine dust is not good. Therefore, there is a need to develop a high-efficiency and durable alloy steel shot screening device, which can realize multistage accurate sorting, automatic ash removal and broken steel shot recovery, and simultaneously reduce energy consumption and maintenance cost so as to meet the high requirements of modern polishing technology on steel shot quality. Disclosure of utility model The utility model aims to provide an alloy steel shot screening device for polishing the surface of an aluminum casting, which is used for solving the problems in the background art.
