ABSTRACT:
An apparatus for removing solids from a solids upflow vessel, preferably an upflow retort, which includes a horizontally reciprocatable carriage containing a vertical feed cylinder that extends downward from a horizontal seal plate. A vertically reciprocatable piston is located inside the feed cylinder. One section of the seal plate contains a hole and a sliding door for opening and closing the hole. During normal operations when the apparatus is used to feed solids from a feed chute to an upflow vessel, the carriage is reciprocated between a first stationary position wherein the feed cylinder is aligned with the outlet of the solids feed chute while at least a portion of the closed hole in the seal plate is aligned with and below the inlet to the upflow vessel, and a second stationary position wherein the feed cylinder is aligned with the inlet to the upflow vessel while another section of the seal plate is aligned with the outlet from the feed chute. A tram-like suspension system moveably supports the carriage from elevated structural rails. When it is desired to remove solids from the upflow vessel during a maintenance shutdown, the hole in the seal plate is opened and the carriage is moved between its first and second stationary positions such that at least a portion of the open hole is aligned with and below the inlet to the upflow vessel.
