Grain-bulk pipe-inserted curtain-wall ventilating system

Abstract

The invention discloses a grain-bulk pipe-inserted curtain-wall ventilating system. The grain-bulk pipe-inserted curtain-wall ventilating system is structurally characterized in that negative-pressure draught fans (2) are arranged on the two sides of a granary (1), and air outlets of the negative-pressure draught fans (2) are connected with ventilating space (3), located at the upper portions of grain bulks (6), in the granary (1) through functional devices (5); a porous air inlet pipe (4) communicated with the ventilating space (3) is arranged in the grain bulks (6); porous ventilating board curtain walls (7) are arranged on the inner side of the inner side wall of the granary (1), air outlet channels (8) are formed in the inner walls between the porous ventilating board curtain walls (7) and the granary (1), air inlets of the negative-pressure draught fans (2) are communicated with the air outlet channels (8), and the tops of the grain bulks (6) are covered with a plastic film (9). According to the grain-bulk pipe-inserted curtain-wall ventilating system, a ground cage and a geosyncline ventilating system of an original granary are completely omitted, a grain transporting device can directly enter the granary, and the in-and-out granary efficiency is greatly improved; due to formed transverse ventilating, center cooling can be achieved in a layered and directional mode, heat gathering can be solved in a layered and directional mode, and implementation and operation are easy.

Description

technical field [0001] The invention relates to a ventilation system for grain piles, which is used for controlling elements such as moisture of grain and agricultural by-products, improving the quality of grain and agricultural by-products and the technological level of agricultural modernization equipment. Background technique [0002] The granary is a warehouse for grain storage or transshipment. In order to prevent the grain piles from becoming moldy, damp, infested with insects, and overheated and deteriorated, it is generally necessary to maintain good ventilation and airtight conditions. At present, some existing simple granaries simply use exhaust fans for ventilation. The tall one-story warehouses use cages on the ground and floor trough ventilation systems. Or mechanized operation is difficult to enter and exit the warehouse and the efficiency is low. Contents of the invention [0003] The object of the present invention is to address the deficiencies in the pri...

AI Technical Summary

Problems solved by technology

At present, some existing simple granaries simply use exhaust fans for ventilation, and tall one-story warehouses use cages on the ground, floor trough ventilation systems, etc., the ventilation effect is not good enough, it is not suitable for modern granaries, or the structure is more complicated. Or mechanized operation is difficult to enter and exit the warehouse and the efficiency is low
