Technical Field
[0001] The utility model relates to the technical field of vertical grain bin grain cooling, and specifically discloses a vertical grain bin grain cooling system. Background Art
[0002] At present, the temperature of the grain bin needs to be controlled. The traditional temperature control system cools the grain pile in the bin effectively through the ventilation system of the silo. However, when the mechanical ventilation time is short, it has little impact on the humidity in the bin. When the grain is stored in this state, it may cause mildew and heat generation of the grain pile, thus posing a huge threat to the safety of stored grain.
[0003] To solve the above problems, a patent with the publication number CN215269562U discloses a grain cooling system for variable-pressure whole-bin cooling in a grain bin, which includes a cooler and a storage bin. A film is arranged in the storage bin, and the film divides the storage bin into a grain storage cavity. The film and the grain storage cavity form an airbag. The cooler is respectively connected with an air inlet pipe and a return air pipe, and the air inlet pipe and the return air pipe are respectively communicated with the grain storage cavity. It also includes a controller and a wireless pressure sensor. The wireless pressure sensor is arranged in the grain storage cavity, the controller is in communication connection with the wireless pressure sensor, and the controller is in communication connection with the cooler.
[0004] In the above solution, the grain in the storage bin is cooled by the grain cooler, but the grain cooler is connected to the storage bin through the side wall, resulting in uneven cooling of the grain in the storage bin by the cold air, and poor cooling of the grain far from the connection between the grain cooler and the storage bin.
