Twin-granary which can rapidly cool the inner layer stored grain

Abstract

The invention discloses a twin-granary which can rapidly cool the inner layer stored grain. The twin-granary comprises a twin-granary warehouse and a grain discharge device. The twin-granary warehouse has a first warehouse and a second warehouse. Each of the first and second warehouses is provided with a ventilation heat exchanging system. The grain discharge device comprises a grain discharge box and a drive device. The grain discharge box comprises a box body, a first screw feeder, a second screw feeder, a first material inlet, a second material inlet, a material outlet and a pulley. The first screw feeder comprises a first rotating shaft, a first spiral plate and a first single-direction free-wheeling clutch. The second screw feeder comprises a second rotating shaft, a second spiral plate and a second single-direction free-wheeling clutch. The spiraling direction of the first spiral plate and the spiraling direction of the second spiral plate are opposite to each other. Both the first and second free-wheeling clutches are arranged in a shaft hole of the pulley. The locking direction of the first single-direction free-wheeling clutch and the locking direction of the second single-direction free-wheeling clutch are opposite to each other. The twin-granary which can rapidly cool the inner layer stored grain has the advantages of being compact and reasonable in structure, and low in cost.

Description

technical field [0001] The invention belongs to the technical field of structural design of a double-body granary, and in particular relates to a double-body granary capable of rapidly cooling inner grain storage. Background technique [0002] The food problem is one of the urgent problems that attract worldwide attention. my country, as the most populous country in the world, consumes a large amount of food every year. Only with food can a country develop industry, national defense, service industry, scientific and cultural undertakings in a stable and healthy manner. The food issue is not only an economic and people's livelihood issue, but also a development and security issue. With the rapid development of green food and the continuous improvement of people's living standards, green grain storage technology has made great progress in our country. Under the guidance of "China's Grain Storage Ecosystem Theory System", my country's grain storage concept is undergoing profou...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the traditional granaries adopt a single-body design, which can only store one kind of grain at the same time, and has a single function

There are also some granaries that adopt a double-body design, but use two separate sets of unloading devices to unload grain separately, resulting in the disadvantages of occupying a large area and high cost

In addition, the ventilation system of traditional granaries mostly uses surface heat exchange to cool down. When the grain storage is deep and the area is wide, it is difficult to quickly cool down the inner grain storage.
