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 return flights and arcuate ends trained about sprockets carried by the housing assembly at the ends of the plate. A series of spaced perforated particle moving structures extend between the chains and are operable during the movement of the chains through their operative flight to move therewith over the upper surface of the plate and upwardly through the space thereover defined by the upper periphery of the housing assembly so that particles introduced into the lower portion of the space through the inlet are moved positively inwardly through the liquid free surface and then discharged through the outlet in a condition in which the liquid has been substantially drained therefrom. |
