Embodiment Construction

[0017] The present invention will be further described below in conjunction with the examples, but the content of the present invention is not limited thereto.

[0018] The bungalow ventilation and cooling device provided by the present invention comprises a bungalow with an air inlet and an air outlet, wherein a plurality of air inlets 4 are arranged above the rear wall of the bungalow 5 with a vault, and a plurality of outlets are arranged above the front wall. The tuyere 9 is provided with an air duct 11 on the upper layer 12 of the grain pile in the bungalow 5, and the air duct is composed of multiple groups of parallel-laid sub-pipes according to the capacity of the flat bin, and each group of pipes is connected to the air inlet 4. The air main pipe 3 and several ventilation branch pipes 11 are composed. The air inlet main pipe 3 is connected to the cold air pipe 2 outside the warehouse through the air inlet 4 on the back wall of the flat warehouse, and the cold air pipe 2...

Abstract

The invention provides flat storage temperature-controlling grain-storing method and device thereof. The device comprises a flat storage with an air inlet and an air outlet, wherein an air duct with holes is provided at the upper layer of the grain stack of the flat storage 0. 6-0. 8m to the surface of the grain, an air inlet is connected with the air inlet of the flat storage, and an axial fan is fixed at the air outlet of the flat storage. Negative pressure is formed at the upper layer of the grain stack in the flat storage and the space above to force the cold air out of the flat storage to pass through the upper layer of the grain stack by the air duct and enter the upper space of the flat storage, thereby replacing the warm air at the upper layer of the grain stack of the flat storage and space above, reducing the temperature of the heat insulation chaff and space in the storage while reducing the temperature of upper grain, saving energy, reducing consumption, cutting the cost, further enhancing the aeration-cooling effect, delaying deterioration time of the grains, raising grain-storing fresh-keeping effect at low temperature, and making sure the grain-storing safety.

Description

technical field [0001] The invention relates to a temperature-controlled grain storage method, in particular to a temperature-controlled grain storage method and a device for a bungalow warehouse, belonging to the technical field of storage management and equipment. Background technique [0002] Low-temperature grain storage is the most promising green ecological grain storage technology in the field of grain storage in the future. It has been widely used in the bungalows of many grain storage enterprises in my country. Received good results. However, in the one-storey warehouse that implements low-temperature grain storage, in the high temperature season of summer and tropical regions, the temperature of the grain pile in the warehouse will also increase due to the high temperature outside the warehouse. In particular, the temperature of the upper layer of the grain pile is easier to rise than the temperature of the middle and lower layers, which directly affects the effect...
