Description

Technical Field

[0001] The utility model relates to the technical field of casting desanding, in particular to a casting desanding machine. Background Art

[0002] The sand removal of castings is one of the important processes in the sand casting production process. The casting desanding machine is a device used to separate castings and molding sand. During the desanding process, due to the vibration of the equipment, the sand is scattered and the dust is large, which not only pollutes the surrounding working environment in the factory, but also has a certain impact on human health. In addition, the existing casting desanding machines generally have only one layer of vibrating screen plates. In order to efficiently vibrate and separate the molding sand on the surface of the casting after passing through the screen plate, in addition to vibration, it is also necessary to extend the length of the screen plate and extend the time for the casting to be vibrated and desanded on the screen plate. However, this method occupies a large area, and the desanding machine occupies too large an area and is not convenient for collecting the vibrated molding sand and separating the dust pollution.

[0003] Therefore, in view of the above problems, we provide a casting sand removing machine which can efficiently separate the molding sand and isolate the dust. Utility Model Content
