Super heat conductive grain dryer

Abstract

The invention discloses a super heat conductive grain dryer. The heat source of the dryer is a small amount of coal, the heat transfer material of a heat transfer system is a super heat conductive material, the heat transfer system consists of two round pipes sleeved together, an interlayer is formed between the two round pipes, the two ends of the interlayer round pipe are tightly sealed, the lower end of the interlayer round pipe is connected with a heat sink by a pipe, the interlayer filled with the super conduction material is vacuumized by a vacuum air pump, an extract opening is sealed, and the inner side of the inner layer round pipe is provided with a plurality of throttling plates to restriction plates to restrict the falling speed of grains. When the dryer is to be used, the heat source is ignited, the sink transfers heat to the super conductive material, the super conductive material, after being heated, is instantaneously gasified to transfer heat to the whole vacuum, the gas of the super heat conductive material is cooled to be liquefied after releasing heat, the liquefied gas flows back to the sink to be gasified again to enter a next circulation, grains to be dried are filled into the dryer from the upper opening of the dryer and discharged from the discharge hole arranged at the lower part of the dryer after being dried, and water and vapor are discharged from a grain inlet. The dryer is arranged at a 60 degree angle to the ground surface.

Description

technical field [0001] The invention belongs to the technical field of grain storage, and relates to a dryer, in particular to a superconducting heat grain dryer. Background technique [0002] At present, the drying method before grain storage is mainly by drying in the sun. However, once it encounters continuous cloudy and rainy days, it is easy to mildew if the grains that are not dried are piled up together. Contents of the invention [0003] In order to truly achieve high yields and harvests and return the particles to the warehouse, the present invention has made major breakthroughs in terms of materials and structures. [0004] The technical scheme adopted by the present invention to solve the technical problem is: the heat source of the dryer is a small amount of coal, the heat transfer material in the heat transfer system is a superconducting heat transfer material, and the heat transfer system is two circular tubes that are nested together. The interlayer is form...
