The vibrating fluidized bed dryer is an efficient, energy-saving, and environmentally friendly drying equipment widely used in industries such as chemical, pharmaceutical, food, and light industry to process various powdered and granular materials.
The working principle of the vibrating fluidized bed dryer is that the equipment uses a dual effect of vibration and airflow to ensure uniform flow of materials in the fluidized bed, thereby achieving an efficient drying process. Its working principle is that materials enter the machine from the feeding port, and under the action of vibration force, the materials are continuously thrown forward in the horizontal direction. At the same time, hot air exchanges heat with wet materials through the fluidized bed upwards. Wet air is discharged from the exhaust port after being dedusted by the cyclone separator, while dry materials are discharged from the exhaust port.
The internal structure of the vibrating fluidized bed dryer mainly includes key components such as the inlet mechanism, bed body, vibration mechanism, bracket, fluidization chamber, and distribution plate, as shown below:
♦ Inlet mechanism: composed of inlet duct, inlet chamber, gas pre distributor, and gas distribution plate, its main function is to deliver air into the dryer and ensure uniform gas distribution.
♦ Bed body: including shell, inlet and outlet, air duct and other parts. The shell provides a closed working space for the dryer, the inlet and outlet are used for the entry and exit of materials, and the air duct is the channel for air flow.
♦ Vibration mechanism: composed of a vibration motor and a spring support. The vibration motor generates vibration, allowing the materials inside the dryer to roll and dry fully, while the spring support is used to reduce vibration, protect the structure of the dryer, and reduce noise.
♦ Bracket: Designed according to installation requirements, it is used to support the entire dryer and ensure its stable operation.
♦ Fluidization chamber and distribution plate: In the fluidization chamber, materials are moved from the inlet to the outlet by vibration and airflow, and present a fluidized state. The distribution board is a key component to ensure normal operation, and its aperture, hole type, and opening rate need to be selected according to different materials to ensure uniform gas flow through the holes.
