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

Abstract

The invention discloses a high-efficiency grain flotation dedusting and sand removal device, which comprises a feed pipe, a flow meter, a water inlet pipe, a screening box, a vibrating sieve plate, a runner, a rotating shaft, a liquid level gauge, an impeller, a sundry discharge pipe, Grain discharge pipe and drying box, the feed pipe is connected with the screening box, the feeding pipe is provided with an inclined filter, the water inlet pipe is connected with the upper part of the screening box, the water inlet pipe is provided with a flow meter, and the screening box is provided with a liquid filter. Position gauge, a transparent glass plate is installed on the side wall of the screening box, a rotating shaft is installed in the screening box, an impeller is installed at the bottom of the rotating shaft, a vibrating sieve plate is installed in the screening box, and the two ends of the vibrating sieve plate are connected to the outer edge of the runner through the connecting piece. Connection, one side of the screening box is provided with a debris discharge pipe and a grain discharge pipe from top to bottom, and one end of the grain discharge pipe is connected with the drying box. The invention prevents the air from being covered with dust, ensures the health of farmers, makes sand and gravel sink to the bottom due to buoyancy, ensures the quality of products, has a simple structure, is convenient to use, and is beneficial to popularization.

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
