DUST REMOVING MACHINE FOR GRAIN DRYING MACHINE

摘要

PURPOSE: To treat the dust discharged from a grain drying machine without pollution by pendently installing the aperture of an exhaust duct and the aperture of a dust discharge duct on the water surface of a water storage tank and introducing the dust discharge section of the dust discharge duct into the exhaust section of the exhaust duct having a large diameter. ;CONSTITUTION: The dust mixed in the exhaust air from the exhaust pipe a₁ of the grain drying machine is blown into the water stored in the water storage tank 3 from the exhaust section 1' of the exhaust duct 1. The exhaust dusty air is simultaneously blown into the water from the dust discharge section 4' of the dust discharge duct 4 installed in combination as well and, therefore, a surge phenomenon arises on the water surface by the wind pressures of both ways and while the water surface is kept stirred, both of the dust are settled in the settled water and are suspended and guided, by which the dust is surely removed. At this time, the surge stirring phenomenon is induced in the exhaust section 1' of the exhaust duct 1 formed to the small diameter and is widened outward and, therefore, the dust removal is additionally improved if the dust discharge section 4' of the dust discharge duct 4 is previously introduced into the exhaust section 1' of the exhaust duct 1 formed to the large diameter.;COPYRIGHT: (C)1996,JPO
