Embodiment 2

[0022] Such as figure 2 As shown, the difference from Embodiment 1 lies in that: in this embodiment, a vibrator 30 is fixed outside the dryer housing 10 by bolts. In the process of cleaning the adhesive ethvanillin on the inner wall of the dryer, the vibrator 30 is turned on, and the vibration of the vibrator 30 will also cause the ethvanillin stuck on the inner wall of the dryer housing 10 to fall off.

[0023] Specific working principle:

[0024] Such as figure 1 As shown, in specific use, the ethyl vanillin in the dryer is blown up by the hot air from bottom to top, and some of the blown up ethyl vanillin particles will stick to the inner wall of the dryer shell Above, the dried ethvanillin is discharged from the discharge port 12. Since one end of the pressure pipe 22 is connected to the discharge port 12, under the action of the blower 21, part of the acetylvanillin particles discharged from the discharge port 12 is subjected to pressure Pipe 22, six branch pipes 23, and fi...

Abstract

The invention discloses a fluidized bed dryer for isovanillin production. The fluidized bed dryer for isovanillin production comprises a dryer shell; a material inlet and a material outlet are formed in the dryer shell; a cleaning structure is further arranged. The cleaning structure comprises an air blower, a pressure pipeline and spray nozzles, wherein one end of the pressure pipeline is communicated with the material outlet; multiple branch pipes are connected to the pressure pipeline; each branch pipe is connected with the corresponding spray nozzle; the multiple spray nozzles are all located in the dryer shell; the multiple spray nozzles are distributed in the dryer shell in the circumferential direction of the dryer shell; an outlet of each spray nozzle faces the inner wall of the dryer shell. By means of the fluidized bed dryer for isovanillin production, isovanillin particles stuck to the inner wall of the dryer can be automatically cleaned, manual cleaning is not needed, and the fluidized bed dryer for isovanillin production is quite convenient to use.

Description

Technical field [0001] The invention belongs to the need to use a heating method to dry solid materials or products, and specifically relates to a fluidized bed dryer for the production of ethvanillin. Background technique [0002] The boiling fluidized bed dryer is a drying device that heats and dehumidifies granular solids. The boiling fluidized bed dryer can dry small granular solids. The solid particles are blown up by hot air from the bottom to form a similar The liquid boiling effect ensures that the particles will not stick while removing water. [0003] The boiling fluidized bed dryer in the prior art has a narrow application range, and is generally used to treat solid particles between 30um-6mm in crystalline particles, and cannot be applied to solid particles with large viscosity. It is used to treat solid particles with too small particles and excessive viscosity. In the case of particles, the boiling effect is difficult to form due to the adhesion between the solid par...
