High efficiency cereal flotation, dust removing and sand gravel removing device

Abstract

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.

Description

technical field [0001] The invention relates to an agricultural equipment, in particular to a high-efficiency grain flotation dust removal and sand removal device. Background technique [0002] Grain impurity removal is an indispensable step in the grain processing process. It includes grain screening and dust removal. The principle of screening is to separate according to the width, thickness or shape of the material, and to separate according to the thickness of the grain. The rectangular sieve is separated according to the thickness of the material; to separate according to the width of the grain: round The shape of the sieve is mainly separated according to the width of the material; the separation is based on the shape of the grain, and the triangular sieve is mainly separated according to the shape of the material. Grain sifters on the market are generally highly automated equipment. On the one hand, the cost is high; Dust removal is generally beneficial to the scree...

AI Technical Summary

Problems solved by technology

Grain sifters on the market are generally highly automated equipment. On the one hand, the cost is high; on the other hand, there are not many available hours in a year, and the effective utilization rate is low

Dust removal is generally beneficial to the screening of different displacements of grain and dust drifting under the action of the blower, but this type of dust removal greatly increases the concentration of dust in the air, which seriously affects the health of the farmers' respiratory tract. At the same time, some small sand and gravel are due to the gravity of the grain It is almost difficult to separate, so that the sweat in the product will affect the quality of the product
