Abstract
Abstract An improved slurry distribution box for use with moving bed filters, preferably a tilting pan vacuum filter is disclosed herein. The distribution box is a horizontally mounted box with a flat side transverse to the path of the filter pans, the flat side having a coextensive opening therein and a gate pivotally mounted from the top opposite the opening and acting together with the opening to define a discharge port. Adjustably mounted counterweights are cantilevered from the front of the gate to provide a biasing force to hold the gate against the opening. Preferably the gate is angularly bent at its bottom to provide a slight taper to the discharge port formed by the gate and the opening so as to distribute slurry evenly over the annular filter surface area of the moving filter.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
209 words
A fluid-distribution apparatus for uniformly feeding fluid onto a moving surface, said distribution apparatus comprising: a box horizontally mounted above said surface, said box having a longitudinally coextending opening therein, said flat side and said opening being transversely located in relation to the surface movement; feed means for feeding fluid into the box, said feed means being communicatingly mounted to said box; a normally closed gate pivotally mounted on said box over and across said opening and forming together with said opening a discharge port, biasing means for applying a force against the gate toward the opening thereby variably opening said discharge port in response to the force of fluid impinging on the gate; baffle means for reducing the velocity of fluid impinging on the gate, said baffle means being mounted transversely to the fluid flow in said box and comprising an upwardly extending vertical dispersion plate attached to the bottom surface of the box and parallel to and at a spaced distance from the discharge port, and a second vertically mounted baffle mounted within said box intermediate the feed means and above and parallel to at a spaced distance from the dispersion plate, said second baffle directing the flow fluid away from said gate and said dispersion plate.
Claim 2
Dependent Claim
209 words
A fluid-distribution apparatus for uniformly feeding fluid onto a moving surface, said distribution apparatus comprising: a box horizontally mounted above said surface, said box having a longitudinally coextending opening therein, said flat side and said opening being transversely located in relation to the surface movement; feed means for feeding fluid into the box, said feed means being communicatingly mounted to said box; a normally closed gate pivotally mounted on said box over and across said opening and forming together with said opening a discharge port, biasing means for applying a force against the gate toward the opening thereby variably opening said discharge port in response to the force of fluid impinging on the gate; baffle means for reducing the velocity of fluid impinging on the gate, said baffle means being mounted transversely to the fluid flow in said box and comprising an upwardly extending vertical dispersion plate attached to the bottom surface of the box and parallel to and at a spaced distance from the discharge port, and a second vertically mounted baffle mounted within said box intermediate the feed means and above and parallel to at a spaced distance from the dispersion plate, said second baffle directing the flow fluid away from said gate and said dispersion plate.
Claim 3
Dependent Claim
55 words
The apparatus of claim 1 wherein said biasing means is adjustable and comprises: a plurality of rods cantilevered from the back of said gate and extending at a 45* angle away from said gate, counterweights sliding mounted on each of said rods; and locking means for fixedly holding said counterweights to each of said rods.
