Vibrating fluidized bed dryer

Abstract

The invention discloses a vibrating fluidized bed dryer which comprises a dryer cavity, a vibrating screen plate and an air inlet pipe. The air inlet pipe is fixed at the bottom of the dryer cavity and supplies dry hot air into the dryer cavity. The vibrating screen plate is elastically connected to the inside of the dryer cavity through a spring. An exhaust cylinder is vertically fixed at the bottom of the dryer cavity. The vibrating screen plate compresses on the end face of the exhaust cylinder through the spring. An air flow pulse component comprises a rotating block, a motor and a rotary shaft. An air guide hole is formed in the center of the rotating block. The axis of the air guide hole is vertical to the rotating axis of the rotating block. The rotating block rotates in the inner wall of the air inlet pipe through the motor. By the air flow pulse component, the vibrating screen plate compressed by the spring can be lifted and drop under the pushing of the air flow, and vibration is generated. Compared with the shock excitation manners of shock excitation motors, the vibrating fluidized bed dryer is low in noise, simple in structure and low in fault rate.

Description

technical field [0001] The invention relates to a vibrating fluidized bed dryer, which belongs to the field of fluidized beds. Background technique [0002] The traditional vibrating fluidized bed vibrates through an exciting motor. This kind of vibrating fluidized bed has problems such as high working noise and excessive vibration force of the vibrating motor will shorten the life of the equipment. Contents of the invention [0003] In order to achieve the above object, the present invention adopts the following technical solutions: the present invention realizes the vibration of the sieve plate through springs and pulsed air jets, reducing noise and energy loss. [0004] The specific plan is as follows: [0005] A vibrating fluidized bed dryer, comprising a drier cavity, a vibrating sieve plate, and an air inlet pipe, the vibrating sieve plate is installed inside the drier cavity, and the air inlet pipe is fixed at the bottom of the drier cavity, for Dry hot air is pro...
