摘要： Gravity flow blending system for granular materials by use of novel internal handling means which provides for a continuous, uniform withdrawal of material from a multitude of locations in a large capacity bin. The invention utilizes basic principles of solids rheology to provide for a natural internal self-regulation which makes it possible to use this system for a wide range of material discharge rates and granular material types.

摘要： Apparatus is disclosed for blending free-flowing granular materials comprising: an outer chamber having walls which converge toward and terminate in outlet means at the base thereof; substantially vertically-positioned fenestrated blending tube means spaced above said outlet means having a plurality of entrance means therein; solid, conveying tube means extending substantially vertically through and coaxial within said blending tube means and defining an annular space therebetween; an entrainment zone positioned between said base of said conveying tube means and the base portion of said chamber; and gas inlet means positioned in said chamber to discharge gas upwardly into and through said entrainment zone toward the base inlet of said conveying tube means; the distance of the point of gas inlet discharge into said entrainment zone from said base of said chamber is defined by the equation:X .ltoreq. L - r Tan .alpha.wherein X is the distance between the base of said chamber and said point of discharge, L is the overall distance between said base of said chamber and said base of said conveying tube, r is the outer radius of said conveying tube and .alpha. is the angle of repose of the granular material being blended.

摘要： The plugging of fluidized solids in long transfer lines is a particularly troublesome problem from an operational standpoint. Obstructions are cleared by closing off the transfer line at both ends, introducing an inert (non-deleterious) gas into the conduit at a few atmospheres pressure above the pressure at the conduit output, maintaining the gas pressure for a time to allow pressure equilization along the conduit, and thereafter opening the conduit outlet to permit the plugged solids to refluidize and then clear the line.
摘要翻译：长期输送管线中流化固体的堵塞从操作的角度来看是一个特别麻烦的问题。通过关闭两端的输送管线来清除阻塞物，在高于管道输出压力的几个大气压下，将惰性（无毒）气体引入管道中，保持气体压力一段时间以允许压力平衡导管，然后打开导管出口以允许堵塞的固体回流，然后清除管线。
