Technical Field

[0001] The utility model relates to the technical field of rotary drying, in particular to a high-efficiency rotary drying machine with a heat circulation function. Background Art

[0002] Drying equipment, also known as dryer and dryer, is a device used for drying operations. It vaporizes the moisture in the material by heating to obtain solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. Since natural drying is far from meeting the needs of production development, various mechanized dryers are becoming more and more widely used.

[0003] Common high-efficiency rotary dryers only include drying functions and can dry materials, but lack the function of heat circulation and cannot guarantee efficient drying of materials. Heat is easily accumulated on the upper part of the drying box, making it impossible to dry the materials below the drying box, thus affecting the drying effect.

[0005] In order to overcome the common high-efficiency rotary dryer, the lack of heat circulation function cannot ensure the efficient drying of materials. It is easy for heat to accumulate on the upper part of the drying box, making the material below the drying box unable to dry, affecting the drying effect.

Heat is easily accumulated on the upper part of the drying box, making it impossible to dry the material below the drying box, thereby affecting the drying effect.

After the drying operation is completed, the discharge port is opened, and the material is driven by the first stirring plate and the second stirring plate and discharged from the discharge port due to gravity.

[0012] Preferably, an exhaust fan is provided at the position corresponding to the air outlet at the other end of the heat circulation air duct.
