Description
Technical Field
[0001] This utility model belongs to the field of screening device technology, specifically a screening device for a double cone dryer. Background Technology
[0002] The double cone dryer is a new type of drying equipment that integrates mixing and drying functions. It is widely used in chemical, pharmaceutical, food, metallurgical and other industries for drying powdery, granular and lumpy materials.
[0003] The double-cone dryer is a rotating double-cone tank. Under vacuum conditions, steam or hot water is introduced into the jacket for heating, and the heat comes into contact with the wet material through the inner wall of the tank. The water vapor evaporated from the wet material after absorbing heat is removed by a vacuum pump through the vacuum exhaust pipe. Because the tank is under vacuum, and the rotation of the tank causes the material to continuously move up and down and inside and out, the drying speed is accelerated, drying efficiency is improved, and uniform drying is achieved.
[0004] The double cone dryer dries materials through rotation and vacuum heating. When the material is turned over in the tank, the particle size distribution may be uneven due to density differences, resulting in the final product not meeting the particle size standard. The dried material needs to be screened. During screening, the material will block the screen plate, which will affect the screening efficiency.
[0005] Therefore, this utility model provides a screening device for a double cone dryer. Utility Model Content
