METHOD OF DISCHARGING CHEMICALS IN FILTER-DRIER USING AGITATION IMPELLER AND THE AGITATION IMPELLER

摘要

The present invention provides an agitation impeller for a filter-drier and a method of discharging chemicals in the filter-drier using the agitation impeller. The agitation impeller is installed in a treatment tank and is fitted over an agitation shaft. Solid chemicals are discharged out of the treatment tank by the agitation impeller which rotates in the normal direction. Left over chemicals that remain on the bottom of the treatment tank are dispersed into the air by gas jetted from the agitation impeller and are discharged out of the treatment tank by the agitation impeller which rotates in the reverse direction.
