Storm water vault having an articulated floating screen filter system

摘要

A storm water nutrient separating vault has a floatable filter basket therein for collecting debris entering the storm water filter vault which basket rises and falls with the water level in the vault. The floatable filter basket has a pair of swiveling trucks attached thereto. Each truck is supported on a generally vertical track mounted to a wall of the vault on one side of the vault's inlet and has a plurality of rollers riding in the track. The floatable filter basket can therefore swivel or tilt while rising or falling with the water level in the vault to maintain an opening in the nutrient collecting basket in front of the vault's inlet for capturing floating debris in the storm water entering the vault.

主权项

1. A storm water nutrient separating vault having an articulated floating screen filter system comprising:
a storm water nutrient separating vault having a plurality of walls and a storm water inlet passing through one said wall; a floatable filter basket located in said nutrient separating vault, said floatable filter basket having an open front end and having a plurality of floats mounted thereto for floating said filter basket with the rise and fall of the water level in the nutrient separating vault; a pair of tracks mounted vertically to said nutrient separating vault adjacent said storm water inlet; a pair of trucks, each truck being swivelly mounted to said filter basket, each said swivelly mounted truck having a plurality of rollers thereon and each said truck riding on said rollers in one said track holding said floating filter basket while allowing the angle at which the floating filter basket floats to vary while each said truck remains parallel with the track regardless of the angle of the floating screen as it moves with the level of water in the vault; whereby a storm water nutrient separating vault has an articulated floating screen filter system therein.
