Ventilation and air-drying system for grain store of grain depot

Abstract

The invention relates to a grain air-drying and ventilation system for a grain store of a grain depot in the grain storage security industry, which aims to solve the problems of high cost of grain storage, air-drying, ventilation and the like, difficulties in the gathering and warehousing of grains in cloudy and rainy days, high labor intensity and waste of time. The scheme is that: a cylindrical hoisting device is arranged on the outer wall of the grain store of the grain depot; the lower part of the grain store of the grain depot forms an inverted prismatoid; an axial screw is arranged on the lowest part of the inverted prismatoid; an inclined air-drying surface is formed on the grain store of the grain depot; the upper part of the grain store of the grain depot realizes the ventilation and air-drying of the grains by utilizing natural wind and sunshine; and the axial screw is arranged at the wall bottom of the grain store of the grain depot to convey the grains of the inverted prismatoid to the cylindrical hoisting device, and the hoisting device hoists the grains at the bottom onto the inclined air-drying surface on the grain store, so the grains are air-dried on the inclined air-drying surface, slide down by self weight and are ventilated for mould prevention, corrosion prevention and temperature reduction by the natural wind. The system has a simple, novel and unique structure, is simple and convenient to use and operate, ensures low labor intensity and remarkable economic efficiency and social effects, can realize the mechanization and automation of a grain air-drying system and greatly improve the labor efficiency, and is a great innovation in the grain storage industry.

Description

technical field [0001] The invention relates to the grain storage safety industry, and more specifically, the invention relates to a grain drying and ventilation system for grain depots and granaries. Background technique [0002] At present, grain storage is a very special industry. Grain storage, drying, ventilation, etc. need to pay costs continuously. From an economic point of view, it is best to store, dry, and ventilate the grains stored in storage, so that the grain enterprises can obtain the maximum profit. The ventilation and drying of grain in the grain depot mainly relies on manual or mechanical spreading of the grain on the ground to use the sun to expose it to the sun. It occupies a large area. Once it suddenly rains and collects it together, it is very difficult and time-consuming to put it into the grain depot. This kind of traditional granary and granary grain is ventilated and dried, which is labor-intensive, time-consuming and labor-intensive, and causes ...
