Abstract
An apparatus, system and method have a rod attached to and extending across a screen to engage with a receptacle. A box is positioned beneath the filtration screen. An air bag is activated to inflate the filtration screen to compress against a plate. A junction extends from the plate, and the air bag rises to move the junction toward the receptacle to compress the rod against the receptacle to hold the rod. The filtration screen may be constructed from mesh material sized to permit materials to flow through the filtration screen. A vibratory element in the box vibrates to assist filtration.
Claims20
An apparatus comprising:
- a rod extending across a screen to engage with a receptacle wherein the rod attaches to the screen;
- a box positioned beneath the screen;
- an air bag activated to inflate toward the screen to compress a sealing gasket embedded in the screen against a plate extending from the receptacle;
- and
- a junction extending from the plate wherein the air bag moves the junction toward the receptacle to compress the rod against the receptacle.
A system comprising:
- a screen that separates solids from liquid from a slurry passing through the screen;
- a rod threaded through the screen;
- a receptacle that receives the rod wherein a protrusion extends from the receptacle to compress against the rod;
- a sealing gasket on the screen wherein the protrusion compresses against the gasket to retain the rod in the receptacle;
- a junction beneath the screen wherein the rod compresses against the protrusion and the junction;
- and
- an air bag that expands to cause the junction to compress the rod and the sealing gasket toward the receptacle.
A method comprising:
- threading a rod through a screen that separates solids from liquid in a slurry flowing through the screen;
- inserting the screen into a receptacle;
- inflating an air bag positioned beneath the screen and partially enclosed by an intermediate piece to move the intermediate piece toward the rod;
- and
- tensioning the screen by moving the rod against the receptacle.
