Abstract:
An apparatus for separating solids from a liquid comprising:a housing having two side walls that are spaced-apart from each other;a plurality of looped barrier members that are disposed side-by-side in a parallel relationship with one another between said side walls and which are spaced-apart from one another so as to define a plurality of looped pathways among adjacent pairs of said barrier members, said barrier members being adapted to trap solid matter in wastewater thereamong when the wastewater is introduced into said housing;a circulating unit mounted on said housing;a driving source unit for activating said circulating unit;a plurality of moving plates mounted on said circulating unit and moved by said circulating unit along a looped path, each of said moving plates extending into and moving along a respective one of said looped pathways when said driving source is activated so as to be adapted to remove the solid matter from said barrier members;a pair of upper driving sprockets mounted rotatably on said side walls about an upper rotary axis transverse to said side walls;a pair of lower driving sprockets mounted rotatably on said side walls about a lower rotary axis parallel to and disposed at a height lower than said upper rotary axis; anda parallel pair of endless chains, each of which is trained on a respective one of said upper driving sprockets and a respective one of said lower driving sprockets;said apparatus further comprising an elongated mounting strip bridging said chains and mounted securely on said chains for moving together with said chains, said moving plates being mounted on said mounting strip.
