Description

Technical Field

[0001] The utility model relates to the technical field of vacuum dryers, in particular to a double-cone rotary vacuum dryer for baking salt. Background Art

[0002] The double cone rotary vacuum dryer is a double cone rotary tank. When the tank is in a vacuum state, steam or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the tank. The water vapor evaporated by the wet material after absorbing heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank is in a vacuum state and the rotation of the tank makes the material constantly flip up and down and inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.

[0003] In the disclosed patent (CN218210471U, a double-cone rotary vacuum dryer), an automatic stirring device is provided. After the material is put into the tank body from the inlet and outlet, the vacuum dryer body is started to rotary dry the material, and the drive motor is started at the same time. After the output shaft of the drive motor rotates, the rotating shaft can be driven to rotate in the tank body through the sealed bearing, and the spiral stirring blades at the lower end are driven to automatically stir the material in the tank body. The structure is simple, the operation is convenient, and the automatic stirring of the material can be realized. Although the automatic stirring of the material can be realized, the material will adhere to the inner wall of the tank during the drying process, which is difficult to clean and easy to cause waste of material. Therefore, we introduce a new double-cone rotary vacuum dryer for roasting salt. Utility Model Content
