Problems solved by technology

The traditional cooling method is mainly the air-conditioning cooling method. On the one hand, air-conditioning cooling consumes a lot of energy, and the equipment purchase and daily energy consumption burden of grain production enterprises increases; on the other hand, the vibration of the air-conditioning compressor installed on the top of the grain depot will partially destroy the grain. storage, forming cracks or even cracks, bringing greater hidden dangers to food safety storage

Embodiment 1

[0017] A self-driven ground cooling cycle and surface heat insulation system for a grain depot, including ground cooling facilities installed underground in the grain depot, water circulation pipes disposed in the inner wall of the grain depot, and solar energy installed on the top wall of the grain depot. The power generation device, the reflective and heat-insulating coating on the outer wall and top wall of the grain depot; the ground-cooled flat-plate solar collector in the solar power generation device is installed on the top of the grain depot, and the main orientation is 207'SW ~ 247' 'SW direction; the water circulation pipes are all set in the semi-hollow walls of the four walls of the grain depot, and are densely distributed in the direction of 155'SE ~ 265'SW. The water circulation pipes are composed of ground cooling pipes, casings, sealants, Composed of waterproof material reinforcement layer, the water inlet and outlet pipes are parallel with gaps.

[0018] The g...

Embodiment 2

[0022] The difference from Example 1 is that the type of grain depot is a shallow round silo. The flat solar heat collector is installed on the top of the bin body and connected with the grain conveying equipment. When there is sunshine in winter, the maximum temperature in the grain depot is maintained at 5-10°C, and when there is no sunshine, the maximum temperature is maintained at 2-6°C; when there is sunshine in summer, the maximum temperature in the grain depot is maintained at 15-25°C. The temperature is maintained at 8-18°C.

Embodiment 3

[0024] The difference from Example 1 is that the address is located at 26 degrees north latitude, and the underground water depth is 15 meters. The middle and upper part of the granary warehouse adopts a semi-hollow wall, and the water circulation pipes are distributed in the semi-hollow walls of the four walls of the granary. SE ~ 265'SW direction, encrypted distribution. The water circulation pipeline on the inner wall of the grain depot is composed of ground cooling pipe, casing, sealant, and waterproof material reinforcement layer. There is no heat insulation layer on the outer wall of the grain depot, and reflective heat insulation paint is sprayed on the outer wall within the direction of 170'SE ~ 270'W and the top wall. In extremely cold winter conditions, the temperature inside the wall is above 2.0 ~ 3.5°C. The flat-plate solar collector is installed on the top of the warehouse, and the main orientation is 220’SW. When there is sunshine in winter, the maximum tempera...

Abstract

The invention discloses a granary self-driven cold circulation and surface heat insulation system. The system comprises an earth cooling device arranged under the ground of the granary body, water circulation pipes arranged on the inner walls of the granary body, a solar energy generation device arranged on the top wall of the granary body, and reflection and heat insulation coatings arranged on the outer walls and the top wall of the granary body. An earth cooling flat-plate solar collector of the solar energy generation device is mounted at the top portion of the granary body, and the main direction of the earth cooling flat-plate solar collector is 207'SW-247'SW. The water circulation pipes are arranged in half-hollow wall bodies of the walls of the granary body in a dense distribution manner, and the main direction of the water circulation pipes is 155'SE-265'SW. By employing the system, the temperature of the interior and top portion of the granary can be greatly reduced to an acceptable range, the grain storage quality for a storage enterprise can be improved, the energy consumption is minimized, and obvious economical and social benefits are brought.

Description

technical field [0001] The invention belongs to the technical field of grain logistics and storage safety, in particular to a self-driven cooling cycle and surface heat insulation system for a grain depot. Background technique [0002] Grain is an important strategic material and special commodity related to the development of the national economy and social harmony and stability. Food security plays an important role in national economic security. All kinds of grain depots play a vital role in undertaking national and local grain reserve tasks. The storage quality of grain is closely related to storage temperature and humidity. Reserved grains are generally suitable for storage below 15°C. If the storage temperature is too high, it will cause grain condensation, heat and mold. However, during long-term grain storage, affected by light, most grain depots heat up rapidly in the noon and afternoon, and the temperature at the top and upper part of the grain warehouse can even...
