Wind-distribution-plate device for drying fluidization bed

Abstract

The invention provides a wind-distribution-plate device for a drying fluidization bed. The wind-distribution-plate device comprises connecting rods, a hot wind pipe, guiding rods, circular rings, stirring blades and protruding blocks, wherein the connecting rods are fixed inside an air inlet pipe, the hot wind pipe is arranged in a drying fluidization bed body, and the connecting rods sleeve the hot wind pipe; the upper end of the hot wind pipe penetrates through a wind distribution plate, the guiding rods are fixed on the annular side face of the hot wind pipe, and are arranged on the upper side of the wind distribution plate, the circular rings sleeve the guiding rods, the protruding blocks are fixed on the annular side faces of the circular rings, and the stirring blades are arranged between the protruding blocks; it is achieved that the stirring blades continually rotate to form turbulent flow with hot wind blown by wind distribution holes, materials in the drying fluidization bedbody are continually impacted, and it is thus achieved that the material drying speed is increased, and the drying effect is improved; due to special constructions of the wind distribution plate and the wind distribution holes, the service life of the wind distribution plate is prolonged.

Description

technical field [0001] The invention relates to an air distribution plate device used for drying a fluidized bed, and belongs to the field of drying fluidized bed equipment. Background technique [0002] In the prior art, the existing air distribution plates have uniform protrusions on them respectively, and circular air distribution holes are arranged on the sides of the protrusions, which do not have enough turbulence for the material. At the same time, during long-term operation, the distribution board The protrusions on the air plate will be greatly worn, and the air distribution holes are easily blocked by materials, resulting in the continuous reduction of the fluidized drying effect of the fluidized bed. The existing air distribution plate device for drying the fluidized bed does not disturb Flow mechanism, resulting in slow drying speed and low heat utilization rate. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of th...
