The invention discloses a high efficiency cereal flotation, dust removing and sand gravel removing device. The device comprises a feed
pipe, a flow meter, a water inlet
pipe, a screen box, a vibrating screen plate, rotating wheels, a rotating shaft, a liquid-level meter, an
impeller, a sundries
discharge pipe, a cereal
discharge pipe and a
drying box, wherein the feed pipe is connected with the screen box; an inclined filter screen is arranged in the feed pipe; the water inlet pipe communicates with the upper part of the screen box; the flow meter is arranged on the water inlet pipe; the liquid-level meter is arranged on the screen box; a piece of transparent glass plate is mounted on one side wall of the screen box; the rotating shaft is arranged in the screen box; the
impeller is mounted at the bottom end of the rotating shaft; the vibrating screen plate is arranged in the screen box; the two ends of the vibrating screen plate are in point connection with the outer side ends of the rotating wheels through connecting pieces separately; the sundries
discharge pipe and the cereal discharge pipe are arranged on one side of the screen box from top to bottom; and one end of the cereal discharge pipe communicates with the
drying box. According to the high efficiency cereal flotation, dust removing and sand gravel removing device, that the air is covered with dust is avoided, the peasants' health is ensured, sand gravels and the like sink to the bottom due to
buoyancy, the product quality is ensured, the structure is simple, the use is convenient, and the popularization is facilitated.
