Granary heat dissipation system based on intelligent control

Abstract

The invention discloses a granary heat dissipation system based on intelligent control. The system comprises a granary, an air circulating device, a screw rod device and a temperature field intelligent monitoring and controlling system. The air circulating device is connected to the upper part of the granary to form a circulation loop; the screw rod device comprises a screw rod and a power device; the power device drives the screw rod to rotate so as to carry grains in the granary from the granary bottom to the granary top, and grains at the granary top slide to the granary bottom under the effect of gravity, so that the grains form a circulation loop in the granary; the temperature field intelligent monitoring and controlling system comprises a plurality of temperature sensors and a controller which are arranged in the granary; and the air circulating device and the screw rod device are connected with the controller. The granary heat dissipation system based on intelligent control provided by the invention has a simple structure, is easy to realize, has low energy consumption, and has cooling efficiency which is higher than the heat dissipation efficiency of conventional granary structures.

Description

technical field [0001] The invention relates to the technical field of grain storage, in particular to a granary cooling system based on intelligent control. Background technique [0002] Temperature is an important factor affecting grain quality and safety. Low-temperature grain storage, that is, keeping grain temperature below 15°C for storage, can effectively inhibit grain respiration, prevent insect damage, mildew, and delay aging and other quality deterioration. At present, natural cooling sources or mechanical equipment are mainly used for low-temperature grain storage in China, including natural ventilation cooling, mechanical refrigeration cooling, etc. However, it is difficult to implement modern grain storage warehouses. The design and construction of ordinary large grain warehouses are often restricted by climate characteristics and geographical location. , and requires expensive and complex refrigeration equipment, which consumes a lot of energy, increases the co...

At present, natural cooling sources or mechanical equipment are mainly used for low-temperature grain storage in China, including natural ventilation cooling, mechanical refrigeration cooling, etc. However, it is difficult to implement modern grain storage warehouses. The design and construction of ordinary large grain warehouses are often restricted by climate characteristics and geographical location. , and requires expensive and complex refrigeration equipment, which consumes a lot of energy, increases the cost of grain storage, and increases the difficulty of implementation

The technology of using natural cold sources and mechanical equipment to realize low-temperature grain storage throughout the year has not been widely applied and promoted so far
