Abstract
The invention discloses a drying bin with a cooling section; and the drying bin consists of a shell, an inner bin, a heat conducting working medium and safety valves. 2-3 safety valves are arranged on the shell; an inner cavity between the shell and the inner bin is closed without leaking air; and a proper amount of corresponding heat conducting working medium is in the inner cavity between the shell and the inner bin. The inner bin consists of a bin body and cooling vertical pipes; and one end of the inner bin is a drying section, and the other end is a cooling section. The heat conducting working medium is heated by external heat energy of the shell to change phase and vaporize; heat energy carried by the vaporized heat conducting working medium performs heat conduction and heat exchange for a material through the bin body and the cooling pipes of the inner bin; and the increased heat exchange area increases the heat conduction and heat exchange speed of the heat energy, and reinforces the material drying efficiency to achieve quick material drying purpose. In the material drying process, the drying bin with the cooling section rotates under the effect of external force; the cooling vertical pipes spirally arranged have stirring and propelling functions; the material is not easy to cake during drying in the inner bin; and the dried material is cooled in the cooling section.
Description
Technical field
What the present invention relates to is a kind of dryness storehouse, specifically a kind of dryness storehouse having cooling section.
Background technology
The material such as present grain, food, chemical industry, medicine, agricultural byproducts, herbage, in processing field, needs material is being carried out to heat drying process; The now dryness storehouse heat exchange of drying equipment commercially carries out heat exchange heat radiation mainly with calandria heat radiation, hot air convection mode, but their radiator volume is large, area of dissipation is little, heat energy service efficiency is low.Wet stock often forms caking in dry run, causes the uneven drying of wet stock, affects the oven dry quality of material.The bad control of the gait of march of material in dryness storehouse; material cools in the environment of normal pressure, can be subject to the influence of moisture in the air of surrounding environment, the impact that dried material can be got damp; directly cool under drying regime, the quality of dry material can further be protected.
Hot pipe technique is the heat transfer element that the one of the G.M.Grover invention of LosAlamos National Laboratory of the U.S. in 1963 is called " heat pipe ", it takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, through heat pipe, the heat of thermal objects is delivered to rapidly outside thermal source, inside heat pipe is by vapour, the liquid phase-change heat transfer of hydraulic fluid, thermal resistance is very little, Natural Circulation heat conduction.
Summary of the invention
