Multilevel combined type dry-method vertical separator

The invention provides a multilevel combined type vertical separator. The multilevel combined type vertical separator is provided with a barrel-shaped shell, a cylinder strut and multiple layers of stepped rotation chutes arranged around the cylinder strut, and the cylinder strut and the stepped rotation chutes are arranged in the barrel-shaped shell. Multilayer separation can be achieved in a limited space. The separation quantity of separation materials can be increased. Moreover, through repeated separation, a primary electromagnetic vibrator and a plurality of secondary electromagnetic vibrators evenly distributed in a layered mode, improvement on the separation precision is ensured; the discharge quantity of gangue is adjusted through an insertion plate, so that products meeting different occasion requirements are produced, the gangue is fully used to the greatest degree rather than being treated like rubbish through a traditional method, resources are used reasonably and fully, and the production cost is lowered. Besides, dust exhausted into the air is treated and meets the requirement of environmental protection. The combined type vertical separator is simple in structure, easy to manufacture and popularize, small in occupied space, suitable for scale separation, high in product rate, controllable, capable of using resources fully and effectively, and low in production cost.
