Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluidized bed dryer technology, and more specifically, to a guide vane for an adjustable-angle fluidized bed dryer. Background Technology
[0002] Fluidized bed dryers are widely used in industrial production due to their advantages such as fast drying speed, high efficiency, and good heat utilization. Their working principle is to use hot air to fluidize the material, and through full contact between the hot air and the material, the moisture in the material is rapidly evaporated, thereby achieving the drying purpose. During the operation of the fluidized bed dryer, the guide vane, as a key component for guiding the hot air flow and regulating the hot air distribution, plays a decisive role in the drying effect.
[0003] Traditional fluidized bed dryers mostly use fixed-installation guide vanes, with the angle of the vanes determined during equipment manufacturing. This prevents flexible adjustment as needed. Different materials have different physical properties such as particle size, density, and moisture content, resulting in varying requirements for hot air flow direction and distribution. Fixed-angle guide vanes cannot meet diverse drying needs, easily leading to uneven drying of materials, with some materials being over-dried while others are under-dried. This reduces product quality and increases energy consumption and production costs. Therefore, an adjustable-angle guide vane for fluidized bed dryers is proposed. Utility Model Content

This facilitates the adjustment of the angle of the guide vane. The limiting wheel can improve the meshing strength of the moving frame and the second gear, thereby improving the driving effect. The limiting plate can limit the movement distance of the moving frame, making it convenient to control and use.
