Abstract
An apparatus, system and method provides for the installation of a filtration screen assembly in a vibratory separator. The apparatus has a screen rail extending across a vibratory separator. A ball box is inserted in the screen rail and encloses vibratory elements. A screen assembly is placed on the ball box parallel to the screen rail and extends across the vibratory separator. An inflatable seal is inserted into the screen rail and receives fluid to inflate and compress the screen assembly against the screen rail. A clamping element is attached to the screen assembly. The inflatable seal compresses the clamping element against the screen rail.
Claims20
An apparatus comprising:
- a screen rail extending across a vibratory separator;
- a ball box inserted in the screen rail wherein the ball box encloses vibratory elements;
- a screen assembly on the ball box wherein the screen assembly is parallel to the screen rail and extends across the vibratory separator;
- and
- an inflatable seal inserted into the screen rail wherein the inflatable seal receives fluid to inflate and compress the screen assembly against the screen rail.
A system comprising:
- a screen with a top side and a bottom side positioned opposite and parallel to the top side;
- a clip configured to receive the screen;
- a joining surface extending from the screen to form a loop;
- and
- a seal inserted beneath the bottom side of the screen wherein the seal inflates to compress the loop to hold the screen against the clip.
A method comprising:
- stretching a screen across side rails positioned opposite to each other;
- inserting a seal into the side rails beneath the screen;
- inflating the seal to expand the seal toward the side rails;
- compressing the seal against the screen to hold the screen against the side rails.
