Abstract:
1. A liquid/solids waste separator comprising: an elongated housing having a front wall, a rear wall, a left side wall, a right side wall, a bottom wall having a front end and a rear end, and a longitudinally extending X-axis; support means for supporting said housing with said rear end of said bottom wall positioned vertically higher than said front end of said bottom wall; an elongated mesh screen for separating solid waste particles from effluent while allowing the liquid portion of the effluent to pass downwardly through said mesh screen; said mesh screen having a top surface and a bottom surface, said mesh screen having a width W means for supporting said elongated mesh screen in said housing at a predetermined height H spray means positioned below said elongated mesh screen that directs a spray of liquid against said bottom surface of said mesh screen to unclog any apertures in said mesh screen that have become clogged; means for connecting said spray means to a fluid source; said spray means comprises a plurality of laterally spaced spray nozzles connected to a transversely extending tube having one end connected to said fluid source; a carriage is connected to each end of said tube and said carriage has a plurality of wheels; there is a track on each lateral side of said mesh screen that allows said spray nozzles to travel beneath most of the length of said mesh screen; drive means for reciprocally driving said carriage back and forth beneath said mesh screen; said drive means comprises a motor that drives a chain passing around longitudinally spaced sprocket gears mounted in said housing; a drive peg extending laterally from said chain is captured by attachment means on said carriage; and said attachment means comprises a pair of vertically extending legs having their bottom ends rigidly connected to said carriage; said legs being longitudinally spaced to provide a vertical slot in which said drive peg is captured while allowing said drive peg to reciprocally travel up and down as said drive peg travels around said sprocket gears.
