Abstract
An improved lifting mechanism for an apparatus for continuously feeding solid particles into a pressure vessel of the type disclosed in U.S. Pat. No. 4,125,384, the lifting mechanism comprising an elongated cylindrical housing assembly operatively disposed with its axis extending at an angle to the horizontal and to the vertical. The housing assembly includes end structures closing the upper and lower ends thereof, a water and particle inlet for pressure communication with the pressure vessel of the apparatus leading downwardly into the interior of the housing assembly adjacent the closed lower end thereof and a particle outlet for pressure communication with the container of the apparatus leading downwardly from the interior of the housing assembly adjacent the closed upper end thereof. A particle supporting plate extends longitudinally within the cylindrical housing assembly between the end portions thereof and is fixedly mounted along the sides thereof between horizontally spaced diametrically opposed portions of the housing assembly. A pair of parallel endless chains have upper operative flights which extend along opposite sides of the upper surface of the plate, lower parallel…
