Description

A kind of feeding device for flash dryer

technical field

The utility model relates to the technical field of flash drying machines, in particular to a feeding device for flash drying machines.

Advantages, the existing flash desiccant is generally composed of a heater, a feeder, a stirring and crushing system, a classifier, a drying main pipe, a cyclone separator, a bag filter, and a fan.

The working principle of the existing flash dryer is: the hot air enters the mixing and crushing drying chamber from the bottom of the dryer at a suitable spraying speed through the inlet pipe, which produces strong shearing, blowing and rotating effects on the materials, and the materials are subjected to centrifugal, Particles are formed by shearing, collision and friction, which strengthens the heat transfer between media. At the bottom of the dryer, the larger and wetter particle clusters are mechanically crushed under the action of the agitator, and the particles with lower water content and smaller particle size are entrained by the rotating air flow and are further dried during the upward process. Due to the gas-solid two-phase As a rotating flow, the inertia of the solid phase is greater than that of the gas phase, and the relative velocity between the solid and gas phases is relatively high, which strengthens the heat transfer between the two phases and improves the working efficiency of the flash dryer.

The existing feeding device of the flash dryer is inconvenient to crush the material, and the agglomerated material entering the dryer body will affect the drying efficiency of the material.
