Vibration fluidized bed

Abstract

The invention relates to a vibration fluidized bed comprising a bed body and a vibration excitation device, wherein the vibration excitation device comprises a front side plate and a rear side plate which are arranged on the front side and the rear side of the bed body separately; an upper eccentric shaft and a lower eccentric shaft which are located under the bed body are rotationally arranged between the front side plate and the rear side plate, and the upper eccentric shaft is located above the lower eccentric shaft; a motor in transmission fit with the rear end of the upper eccentric shaft is arranged on the rear side plate, and the front end of the upper eccentric shaft is in transmission fit with the lower eccentric shaft through a gear; and the transmission ratio of gear transmission is 1. The bed body of the vibration fluidized bed can be uniformly vibrated to push materials, and does not generate resonance phenomenon.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a vibrating fluidized bed. Background technique [0002] The common vibrating fluidized bed in the market includes a bed body. Vibration motors are arranged on the front and rear sides of the bed body. The vibration motors are located at the center of gravity of the bed body. The center tube is connected together to form a vibration source. The bed body is provided with a punching material board for carrying materials. The material on the punching material board produces directional vibration under the excitation force of the vibration motor. Throw the material horizontally. [0003] Common vibrating fluidized beds on the market have the following problems: the quality of the vibration source is relatively heavy, and the heavy vibration source will cause a large burden on the bed body, which will easily lead to cracking of the bed board; the vibration of the vibration s...

Problems solved by technology

[0003] Common vibrating fluidized beds on the market have the following problems: the quality of the vibration source is relatively heavy, and the heavy vibration source will cause a large burden on the bed body, which will easily lead to cracking of the bed board; the vibration of the vibration source belongs to point vibration, and The distance between the vibration motors on the front and rear sides is relatively wide, so the installation and debugging of the vibration motors on the front and rear sides is difficult, and the vibration synchronization is poor, which leads to uneven distribution of materials on the punching material board. It is prone to material bias flow, channel flow, and fast and slow flow rate; the bed is prone to resonance, resulting in low service life of the bed
