Oil-sludge filtration system having a free floating weir box
View Patent ↗A system for consolidating and removing contaminate such as paint sludge or oils from a fluid mixture. A contaminate tank receives a supply of the fluid mixture containing contaminate from a source such as a manufacturing line where overspray of paints or cleaning solutions containing washed away oils are collected. A free floating weir floats on the surface of the contaminate tank and mechanically separates and removes contaminate from a surface of the contaminate tank and concentrates the contaminate in a consolidation tank. In the consolidation tanks the contaminate is further separated and collected for disposal.
1. A system for consolidating and removing contaminate such as paint sludge or oils from a fluid mixture, the system comprising:
a contaminate tank receiving a supply of the fluid mixture containing contaminate;
a floating weir free floating on the surface of the contaminate tank for mechanically separating and removing the contaminate from a surface of the fluid mixture collected in the contaminate tank;
a consolidation tank for receiving the contaminate from contaminate tank, wherein said consolidation tank includes a surface scraper for collecting contaminate proximate to the surface of the consolidation tank;
a contaminate chute operatively associated with the scraper for receiving the contaminate removed by the scraper;
a drying bag for receiving contaminate from the contaminate chute;
a pump screen dividing said contaminate tank into a first section where said fluid mixture enters and a second section where a portion of said fluid mixture exits said contaminate tank; and
one or more booth pumps contained in said second section contaminate tank for removing said portion of said fluid mixture.
2. The system of claim 1 wherein said floating weir further comprises:
a suction box having two or more hinged doors each having a float member connected to said two or more hinged doors;
two or more floatation cylinders operably connected to said suction box; and
a vacuum hose connected to said suction box for removing contaminate from said suction box.
3. A system for removing contaminate including consolidated paint sludge or oils from a fluid mixture, the system comprising:
a contaminate tank receiving a supply of the fluid mixture containing contaminate;
a pump screen dividing said contaminate tank into a first section where said fluid mixture enters and a second section where a portion of said fluid mixture exits said contaminate tank;
a first floating weir free floating on the surface of said first section of the contaminate tank for mechanically separating and removing the contaminate from a surface of the fluid mixture collected in said first section;
a second floating weir free floating on the surface of said second section of the contaminate tank for mechanically separating and removing the contaminate from a surface of the fluid mixture collected in said second section;
a consolidation tank for receiving the contaminate collected by said first floating weir and said second floating weir, wherein said consolidation tank includes a surface scraper for collecting contaminate proximate to the surface of the consolidation tank;
a contaminate chute operatively associated with the scraper for receiving the contaminate removed by the scraper, and
a drying bag for receiving contaminate from the contaminate chute.
4. The system of claim 3 further comprising:
one or more booth pumps contained in said second section contaminate tank for removing a portion of said fluid mixture.
5. The system of claim 3 wherein said first floating weir and said second floating weir both further comprise:
a suction box having two or more hinged doors each having a float member connected to said two or more hinged doors;
two or more floatation cylinders operably connected to said suction box; and
a vacuum hose connected to said suction box for removing contaminate from said suction box.
6. A system for removing contaminate including consolidated paint sludge or oils from a fluid mixture, the system comprising:
a contaminate tank receiving a supply of the fluid mixture containing contaminate;
a pump screen dividing said contaminate tank into a first section where said fluid mixture enters and a second section where a portion of said fluid mixture exits said contaminate tank;
a stationary weir operably connected to a stationary surface in said first section of the contaminate tank for mechanically separating and removing the contaminate from a surface of the fluid mixture collected in said first section;
a floating weir free floating on the surface of said second section of the contaminate tank for mechanically separating and removing the contaminate from a surface of the fluid mixture collected in said second section;
a consolidation tank for receiving the contaminate collected by said stationary weir and said floating weir, wherein said consolidation tank includes a surface scraper for collecting contaminate proximate to the surface of the consolidation tank;
a contaminate chute operatively associated with the scraper for receiving the contaminate removed by the scraper;
a drying bag for receiving contaminate from the contaminate chute;
one or more booth pumps contained in said second section of said contaminate tank for removing said portion of said fluid mixture.
7. The system of claim 6 wherein said floating weir further comprises:
a suction box having two or more hinged doors each having a float member connected to said two or more hinged doors;
two or more floatation cylinders operably connected to said suction box; and
a vacuum hose connected to said suction box for removing contaminate from said suction box.
8. The system of claim 7 wherein said stationary weir further comprises:
a suction box having a hinged door having a float member connected to said hinged door;
and
a vacuum hose connected to said suction box for removing contaminate from said suction box.
