Abstract
Description
Technical Field
[0001] This utility model relates to the field of color paste powder drying technology, specifically a drying device for producing color paste powder. Background Technology
[0002] The double-cone rotary vacuum dryer is a double-cone shaped rotary tank. Under vacuum, steam or hot water is introduced into the jacket for heating. The heat comes into contact with the wet material through the inner wall of the tank. The water vapor evaporated after the wet material absorbs heat is extracted by a vacuum pump through a vacuum exhaust pipe. According to application number 202222710638.7, a double-cone rotary vacuum dryer involves placing material into the tank through the inlet and outlet. The dryer body is then started to perform rotary drying. Simultaneously, the drive motor is activated, and the output shaft of the drive motor rotates, driving a rotating shaft through sealed bearings within the tank. This rotation drives the lower spiral stirring blades to automatically stir the material within the tank. The dryer has a simple structure and is easy to operate. It can achieve automatic stirring of materials. The spiral stirring blades repeatedly exchange the upper and lower layers of material, preventing sedimentation of the lower layer and ensuring more thorough stirring, thus improving stirring efficiency, uniform heating of the material, and overall processing efficiency and quality. However, the pigment powder adhering to the inner wall of the tank in this machine cannot be easily cleaned off, resulting in waste of raw materials. Furthermore, the pigment powder adhering to the inner wall of the tank affects the heating of other pigment powders during subsequent drying, reducing the drying efficiency of the pigment powders.
