Verticle Fluidized bed dryer flowchart
Used the draught of fan, natural air flows through purifying cabinet, heater and froms high speed air flow in the hole of material bed, which makes the material into boiling(fluidized)status, during the large area touch between gas and solid phases, mosture of material is veaporated quickly, and thus reaching the purpose of drying.
Hopper is sealed with frame by way of O type air cell, featuring convenient handling. Hopper is equipped with agitator inside, materail is dried uniformly and speedily without boiling dead angle.
Filter bag and cylinder automatic bag shake unit are supplied on the top to avoid materialloss.
With air purifying cabinet, it usesoutdoor air has no influence on air purifying load of purified workshop.
High drying speed, drying time can be freely set up according to features of materials, normally at 10-30min.
The boiling dryer is basically based on the working principle of the fluidized bed, and the basis of the material drying process is the boiling of the powder. At the same time, under the action of exhaust air, the fine powder in the container is filtered through the collecting bag and discharged to the outside, and a large amount of ultrafine powder is generated during the collecting process, whether in the fluid boiling or in the trapping operation. The entire process of boiling and drying is accompanied by ultra-fine powder movement. However, the process of powder movement is often accompanied by two problems of static electricity and dust explosion, which may cause an explosion phenomenon under the guidance of certain factors. At present, when dealing with such problems in China, it is considered that it is feasible to install an explosion-proof motor. This paper discusses the electrostatic and dust explosion problems of powder boiling, and puts forward its own viewpoints on the explosion-proof safety of boiling dryers. The purpose is to make the manufacture and application of such equipment more complete, more reliable and safer.
