Problems solved by technology

[0002] At present, the grain cooling of domestic grain depots adopts air-cooled or water-cooled grain coolers: the air-cooled grain cooler has a simple structure and a high degree of integration, but the air-cooled cooling effect is poor, the condensation temperature is high, wasting electric energy, and is affected by the ambient temperature. Restrictions: The cooling effect of the water-cooled condenser is better than that of air-cooled, and it is not too much affected by the environment. The condensing temperature is lower than that of air-cooled, and the operating cost is moderate. However, an additional cooling tower is required, and the unit needs to be moved, which is extremely inconvenient for actual operation.

Abstract

The invention provides an evaporative cooling type grain cooling machine which comprises an evaporation section and a compression condensation section. One end of a finned evaporator in the evaporation section is connected with an evaporation cold type condenser in the compression condensation section, and the other end of the finned evaporator is connected with a gas-liquid separator in the compression condensation section through a gas return pipeline. An energy regulator is further arranged between the evaporation section and the compression condensation section. The evaporative cooling type grain cooling machine has the beneficial effects that the cooling mode is changed on the basis of original air cooling or water cooling; the evaporation cooling type condenser is adopted; the cooling effect is better than the cooling effect of air cooling and water cooling; the condensation temperature is low; and a compressor selected for the same refrigerating capacity is lower in energy consumption, and therefore the most energy-saving effect is achieved. The evaporative cooling type grain cooling machine is simple in structure, high in integration degree, capable of saving energy compared with air cooling and easy to operate compared with water cooling under the same condition.

Description

technical field [0001] The invention relates to the field of grain storage machines, in particular to an evaporative cooling type grain cooler. Background technique [0002] At present, the grain cooling of domestic grain depots adopts air-cooled or water-cooled grain coolers: the air-cooled grain cooler has a simple structure and a high degree of integration, but the air-cooled cooling effect is poor, the condensation temperature is high, wasting electric energy, and is affected by the ambient temperature. Restrictions: The cooling effect of water-cooled condenser is better than that of air-cooled, and it is not too much affected by the environment. The condensing temperature is lower than that of air-cooled, and the operating cost is moderate. However, an additional cooling tower is required, and the unit needs to be moved, which is extremely inconvenient for actual operation. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art an...
