Description

Technical field [0001] The invention relates to the field of drying water-containing particulate materials, in particular to the intelligent adjustment and static elimination of particles prone to static electricity accumulation and explosion hazard during airflow drying. Background technique [0002] In recent years, with the progress and development of science and technology, vibrating fluidized bed drying technology has been widely used in industrial production and agricultural production. The vibrating fluidized bed is a fluidized bed supported on a set of springs. The excitation motor provides the exciting force to throw the material on the porous plate to the discharge end; hot air blows in from the bottom of the porous plate to transfer heat to the material , And carry the vaporized moisture in the material to be discharged from the exhaust port. For some special high-insulation flammable granular materials in the vibration fluidization drying process, due to the action o...

AI Technical Summary

Problems solved by technology

The granular material on the fluidized bed will accumulate more and more electricity as it continues to move toward the outlet, so it is necessary to effectively eliminate the charged particles near the outlet, but because the bottom of the fluidized bed has a certain pressure Hot air, it is difficult to achieve the entry and uniform mixing of ion wind at this stage
