Grain drying device capable of uniformly transporting air

Abstract

The invention discloses a grain drying device capable of uniformly transporting air. The grain drying device comprises a drying bin, wherein a heat cycle pipeline of an S-shaped structure is fixedly mounted in an inner cavity of the drying bin; the bottom of the right side of the drying bin is fixedly equipped with a hot air blower; the hot air blower is fixedly connected to the tail end of the heat cycle pipeline of the S-shaped structure; the front end of the heat cycle pipeline of the S-shaped structure penetrates through the side wall of the left side of the drying bin and is fixedly connected with an air outlet; the top of the drying bin is fixedly equipped with a material barrel, and an unloading tube is fixedly connected between the bottom of the drying bin and the top side of the front end of the heat cycle pipeline of the S-shaped structure; and a discharge hole is fixedly mounted at the bottom side of the tail end of the heat cycle pipeline of the S-shaped structure. The grain drying device belongs to the grain processing field, achieves the material separating effect, drives grains to loosely and uniformly pass through the heat cycle pipeline of the S-shaped structure, can guarantee that air speed is basically kept consistent while air is conveyed to the front end of the heat cycle pipeline of the S-shaped structure from the tail end of the heat cycle pipeline of theS-shaped structure, and has the characteristics of being high in drying efficiency, and saving energy.

Description

[0001] Technical field: [0002] The invention relates to the field of grain processing, in particular to a grain drying device for uniform air delivery. [0003] Background technique: [0004] Before storing grains such as rice and wheat, it is necessary to dry the grains. The usual method is to expose the grains to the sun. However, this drying method is inefficient and is easily affected by the weather and geographical environment. Many farmers expose the grains to the sun. There will also be safety hazards on the roadside, and now grain dryers are usually used instead of traditional grain drying methods. [0005] The grain dryer is mainly used for drying rice and wheat, and it can also be used for drying rapeseed and other crops after a little improvement. Grain dryer is composed of main components such as coal furnace, motor, axial flow fan and stacking rack. When the grain dryer is working, the motor drives the impeller of the axial flow fan to rotate at a high speed, s...

Problems solved by technology

[0006] The existing grain dryer directly dries the grain with hot air. The temperature in the drying bin is relatively high. If the grain enters the drying bin directly, the quality of the grain will be damaged, and it cannot have a gradual drying effect on the grain. The density in the drying bin cannot be controlled, and the wind speed of the hot air in the drying bin will be affected by the resistance of the grain and the acceleration of gravity, resulting in uneven wind speed and affecting the drying effect of the grain
