JP2523322Y2 - Dehumidifying dryer for circulation type grain dryer - Google Patents

Description

[Detailed description of the invention] [Industrial application field] The invention can be used as a heat source generator in a circulating grain dryer, or air-conditioning (cooling, heating, dehumidifying) in a barn or work place, or flowers in a house. The present invention relates to a dehumidifying / drying device for a circulating grain dryer that can be used for mountain climbing and dehumidification in kind cultivation.

[Prior Art] Conventionally, a dehumidifying and drying apparatus for effectively performing dehumidifying and drying of grains stored in a drying cabinet inside a stationary state by effectively using an evaporator and a condenser of a heat pump has been proposed. Prior to the filing, it is known, for example, as described in JP-B-61-41393 and JP-B-61-42183.

[Problem to be Solved by the Invention] In the conventional dehumidifying and drying apparatus of this type, a heat pump including an evaporator and a condenser used as a heat source of the drying apparatus is a dedicated one for the drying apparatus. It was assembled so as to be a figure.

However, even if an expensive heat pump is used as an integral part of the drying device, the use period of the heat pump is at most about 20 to 30 days throughout the year, and operation is suspended without using it for other purposes in the later period. There is a problem that the uselessness occurs.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object the operation of connecting a hot-air outlet window of an air conditioner to a hot-air inlet of a circulation type grain dryer. When it is not used as a heating source for the circulating grain dryer, separate it from the circulating grain dryer and move it to the required location. It is an object of the present invention to provide a dehumidifying / drying apparatus for a circulating grain dryer which can be used for air conditioning (cooling, heating, dehumidifying) in a workplace or for mountain climbing and dehumidifying in flower cultivation in a house.

[Means for Solving the Problems] In order to achieve the above object, a dehumidifying and drying apparatus for a circulating grain dryer according to the present invention divides the inside of a main body with a caster into two upper and lower chambers, and the upper chamber has outside air. A cold air blowout window with a wind pressure shutter having a suction window and a cool air blowout fan is formed opposite to the front and rear side walls, an evaporator is provided near the outside air suction window, and an outside air suction window with an electric shutter is provided in a lower chamber. A hot air outlet window having a hot air outlet fan and a hot air outlet fan are formed opposite to each other on the left and right side walls, a compressor and a condenser are installed between the outside air inlet window and the hot air outlet window, and a partition is formed to separate the upper chamber from the lower chamber. The air conditioner, which has a horizontally openable communication window with an electric shutter that can be opened and closed on the outside air intake side wall of the wall, can be separated into the hot air intake of the circulating grain dryer with the hot air blowout window on the lower chamber side as a connection port. To form a heat source generator In addition, it is used as a single air conditioner.

[Operation] When it is desired to dry a predetermined amount of grain stuck in the circulation type grain dryer at low temperature, the air conditioner is moved using a caster, and the hot air inlet of the circulation type grain dryer and the air conditioner are moved. Set so that it connects to the hot-air outlet window.

Then, the electric shutter of the lower chamber is operated in the opening direction to open the outside air intake window, the communication window for communicating the upper chamber and the lower chamber is closed, and at the same time the hot air jet fan is rotated, the evaporator of the heat pump is turned on. When the condenser and the compression pump are operated, the outside air sucked into the lower chamber from the outside air suction window is heated by the condensed heat energy when passing through the condenser, becomes dry hot air, and takes out hot air from the hot air blowout window. After being spouted towards the inlet, it is immersed in the circulating grain in the circulating grain dryer, without causing the grain to crack.
Let dry slowly. In addition, when the outside air is hot and humid during the drying operation, the electric shutter is operated to open the communication window to communicate with the upper chamber and the lower chamber, and at the same time, the hot air jet fan is rotated, and then the evaporator of the heat pump, Run compressor and compressor.

Then, the hot and humid outside air sucked into the upper chamber from the outside air suction window is dehydrated when passing through the evaporator, becomes dry air, enters the lower chamber through the communication window, and then passes through the condenser. The hot air is heated by the condensed heat energy, dried hot air is blown out from the hot air blow-out window toward the hot air inlet, and is immersed in the circulating grains to slowly dry the grains.

Therefore, even if the outside air is hot and humid, the dried hot air obtained by the dehumidifying operation can be poured onto the circulating grains to be dried efficiently.

In addition, in seasons other than the drying operation not using as a heat source generator of the circulation type grain dryer, the air conditioner is separated from the circulation type grain dryer, and the air conditioner is installed in a barn or a work place, and a heat pump is installed. At the same time as driving, the cool air blowing fan is rotated to open the wind pressure shutter, and the electric shutter closes the communication window and the outside air intake window,
The air in the barn or workplace is sucked into the upper room from the outside air intake window, becomes cool air when passing through the evaporator, and gushes out of the cool air blowout window, allowing the barn or workplace to be quickly cooled. Or, if the same operation is performed as in the grain drying operation, it can be used not only for heating and dehumidifying work in a barn and a work place, but also for climbing and dehumidifying in cultivation of flowers when used in a house.
