Abstract

This utility model relates to the field of coal preparation technology, specifically a coal washing flotation solid-liquid separation device, including a first outer shell, inside which is a conical inner shell. Multiple connecting rods are fixed to the side walls of the inner shell. Multiple electromagnets arranged in a circular array are fixed inside the first outer shell. A second outer shell is fixed to the bottom of the first outer shell. An inclined first screen plate and a second screen plate are provided inside the second outer shell. A sliding groove adapted to the first and second screen plates is provided inside the second outer shell. Insert rods and stops are provided above both the first and second screen plates. A first discharge hopper and a second discharge hopper are fixed to one side of the second outer shell. A base and a vibrating motor are provided below the second screen plate. Supports are fixed to both sides of the second outer shell. Multiple guide columns and springs are fixed to the bottom of each support. Multiple upright columns are fixed to the top of the base. This utility model facilitates the collection of metal scraps and the removal, cleaning, or replacement of the first and second screen plates.
