Abstract Industrial waste system having lateral lined trenches in a floor comprising spaced parallel side plates with downwardly and inwardly inclined lower sections joined to form a V bottom having a lengthwise gradient sufficient to promote flow of liquids and matter capable of suspension in the liquid from one end to a discharge point at the other end, side wall shoulders for supporting the side plates within the trench with the upper edges of the plates close to floor level, internal filtergrid support shoulders extending horizontally along the inside walls below floor level having filter grids thereon, power driven sprocket and chain means disposed on opposite sides of the side plates and extending substantially the length of the trench liner, carrying transverse scraper bars at a level to scrape the upper surface of the filter grids, and a similarly constructed trunk trench connecting the discharge ends of the lateral trenches, and means for collecting the liquids separate from the waste collected by the scraper bars.
A system according to claim 1 wherein a second trench liner is disposed transversely of and at the discharge end of the lateral liner, and wherein the second trench liner is provided with substantially horizontal conveyor means disposed below and adapted to receive the discharge from the lateral scraper bars, and a V bottom having a lengthwise gradient disposed below and adapted to receive liQuid discharge from the lateral V bottom.
Claim 2
Dependent Claim
49 words
A construction as set forth in claim 1 wherein the grid liners along the upper edges is provided with a lengthwise open tab slot, and in which lengthwise inclined side aprons having means slidably disposed in the slots extend over the chain means on opposite sides of the liner.
Claim 3
Dependent Claim
70 words
A construction as set forth in claim 3 wherein the open top slot is formed by an angle section member comprising two flanks at right angles, one of which has an offset portion offset in a direction opposite to that of the other flank, and wherein the offset is secured to the outside face of the liner with other flanges disposed laterally of the upper edge of the liner side.
Claim 4
Dependent Claim
29 words
A construction as set forth in claim 1 wherein the upper edges of the side liners have outwardly extending lateral flanges for the support of grills at floor level.
Claim 5
Dependent Claim
23 words
A construction as set forth in claim 1 wherein the lower V bottom sections are disposed at a right angle to each other.
