Abstract:
A compression device for feeding a waste material to a reactor, comprising:(a) a waste material feed assembly including a hopper, a supply tube, and a compression tube;(b) each of said supply and compression tubes including feed-inlet and feed-outlet ends;(c) a feed-discharge assembly located between the feed-outlet end of said compression tube and the reactor;(d) a feed auger-screw extending axially in said supply tube between the feed-inlet and feed-outlet ends thereof;(e) a compression auger-screw extending axially in said compression tube between the feed-inlet and feed-outlet ends thereof;(f) said supply and compression tubes being oriented at generally a right angle to each other such that the feed-outlet end of said supply tube is adjacent the feed-inlet end of said compression tube;(g) said compression tube being sloped downwardly towards the reactor to drain fluid from the waste material to the reactor; and(h) a logic means for controlling the rotational speed and rotational direction of said feed and compression auger-screws.
