Problems solved by technology
[0003] The existing special cooling device for grain piles, due to the low temperature of the air outlet and high relative humidity of the air supply, is very easy to form condensation inside the grain pile, which will cause mildew inside the grain pile due to excessive water content, affecting the quality of the grain
[0004] In order to solve the above problems, the traditional method is to install electric heating behind the evaporator to increase the temperature of the air and reduce the relative humidity of the air. Due to the high power of the electric heating, the power load of the equipment increases and the operating cost increases. , thereby affecting the user's use of

The invention provides a reheating type cooling device special for a grain pile. The device comprises a refrigerant circulating system and an air reheating system. The refrigerant circulating system mainly comprises a compressor, a finned condenser and a finned evaporator; and the air reheating system mainly comprises the compressor, an electric three-way control valve, a reservoir, a reheating condenser, a humidity controller and a refrigerant pipeline. The left side end of the compressor is connected with the top end of the finned condenser; an axial flow fan is fixed above the finned condenser in a vertical direction to accelerate air exhaust; the bottom end of the finned condenser is connected with the top end of the reservoir; the upper end of the right side of the reservoir is connected with one end of a solenoid valve and thermostatic expansion valve parallel group; the other end of the solenoid valve and thermostatic expansion valve parallel group is connected with the finned evaporator; and the finned evaporator is connected to one end of the screw compressor to form the refrigerant circulating system. The finned condenser is used, and the contact area is increased, so that the condensation effect is improved.
Description
technical field [0001] The invention belongs to the field of grain storage systems, and in particular relates to a special cooling device for reheating grain piles. Background technique [0002] The special cooling device for grain piles refers to that the refrigeration unit sends cold air into the grain piles through the cage on the ground, and the cold wind discharges the grain piles through the grain gaps, taking away the heat inside the grain piles, thereby reducing the temperature of the grain piles, and ensuring that the grains can be stored for a long time. Mildew occurs to ensure grain quality. The air passing through the grain pile returns to the refrigeration unit through the return air pipe to complete a cycle. [0003] The existing special cooling device for grain piles, due to the low temperature of the air outlet and high relative humidity of the air supply, is very easy to form condensation inside the grain pile, which will cause mildew inside the grain pile ...
