Grain depot overall cooling and drying device

Abstract

The invention belongs to the technical field of grain depot drying and cooling equipment and relates to a grain depot overall cooling and drying device. The device comprises a shell. The device is characterized in that the shell is provided with an outdoor fresh air inlet A, an outdoor fresh air inlet B, an outdoor fresh air outlet, an air supply port and an air return port; the air supply port isconnected with the air inlet of a grain depot through an air supply hose; the air return port is connected with the air return port of the grain depot through a return air hose; a compressor, a condenser, an expansion valve, an evaporator, an air volume adjusting valve A, an air volume adjusting valve B, a three-way solenoid valve, a solenoid valve A, and a solenoid valve B are arranged in the shell; the opening and closing of corresponding solenoid valves can be switched, so that a refrigeration loop and a heating loop can be realized in the device, and therefore, the device has a cooling function and a drying function and can replace an existing grain cooler and grain dryer. With the grain depot overall cooling and drying device of the invention adopted, grain temperature reduction anddrying tasks during grain storage can be completed, so that enterprise equipment procurement costs can be decreased. The device has high practicality and marketability.

Description

technical field [0001] The invention relates to the technical field of drying and cooling equipment for grain depots, in particular to a cooling and drying device for the whole grain depot. Background technique [0002] The whole grain warehouse is a special building for storing grain. In order to ensure the quality of grain storage and avoid grain mold or overheating and spontaneous combustion of grain, it is necessary to control the temperature and humidity in the whole grain warehouse. In the current grain storage, the whole warehouse is cooled by Conventional grain coolers are used to reduce grain temperature, while grain coolers only have the function of lowering grain temperature. Grain dryers are commonly used in grain drying, and grain dryers only have the function of grain drying, and the grain drying uniformity is poor , the unit heat consumption is high, and the drying machine is limited to dry a variety of grains, so it is necessary to purchase a variety of equip...

[0002] The whole grain warehouse is a special building for storing grain. In order to ensure the quality of grain storage and avoid grain mold or overheating and spontaneous combustion of grain, it is necessary to control the temperature and humidity in the whole grain warehouse. In the current grain storage, the whole warehouse is cooled by Conventional grain coolers are used to reduce grain temperature, while grain coolers only have the function of lowering grain temperature. Grain dryers are commonly used in grain drying, and grain dryers only have the function of grain drying, and the grain drying uniformity is poor , the unit heat consumption is high, and the drying machine is limited to dry a variety of grains, so it is necessary to purchase a variety of equipment in the grain storage process, which eventually leads to high equipment procurement costs and low equipment utilization in the grain storage process, and equipment energy consumption advanced questions
