Denisty current baffle for a clarifier tank
View Patent ↗A density current baffle for use in a clarifier tank has a first baffle portion having a lower end, an upper end and an intermediate central portion. The lower end of the baffle portion is coupled to a side wall of the clarifier tank, the upper end of the baffle portion is disposed, at a predefined angle, away from the side wall of the clarifier tank such that the first baffle portion slopes upwardly and away from the side wall. The upper end is configured to receive a mounting bracket having a first end coupled to the end flange and a second end coupled to the side wall of the tank wall. The mounting bracket is a downwardly sloping panel member which together with the first baffle portion form a substantially closed baffle, so that solid materials may be prevented from building up behind the upwardly sloping central baffle portion.
1. A density current baffle for use in a clarifier tank, said density baffle comprising:
a first baffle portion having a lower end and an upper end, said lower end of said first baffle portion being coupled to a side wall of said clarifier tank, said upper end of said first baffle portion being disposed, at a predefined angle, away from said side wail of said clarifier tank such that said first baffle portion slopes upwardly and away from said side wall, and
wherein said first baffle portion is configured to connect with a downwardly sloping panel member, said downwardly sloping panel member having a first end coupled to said upper end of said first baffle portion and a second end coupled to said side wall of said tank wall, wherein said downwardly sloping panel member together with said first baffle portion form a substantially closed baffle, so that solid materials may be prevented from building up behind said upwardly sloping central baffle portion.
2. The density current baffle as claimed in claim 1 , wherein an angle of attachment of said first baffle portion and said downwardly sloping panel member to said tank wall is substantially in the range of 35° to 60°.
3. The density current baffle as claimed in claim 1 , wherein an angle of attachment of said first baffle portion and said downwardly sloping panel member to said tank wall is about 45 degrees.
4. The density current baffle as claimed in claim 1 , wherein the clarifier tank has a water level, said baffle being located below the water level of the clarifier tank.
5. The density current baffle as claimed in claim 1 , wherein the baffle further comprises an end attachment bracket integrally formed with the baffle as a one piece member.
6. The density current baffle as claimed in claim 5 , wherein said end attachment bracket integrally formed with the baffle is configured to be adjustable during installation of said baffle so as to compensate for irregularities in the curvature of said side wall of said clarifier tank.
7. The density current baffle as claimed in claim 1 , wherein the peripheral wall of the clarifier tank has a radius of curvature, and wherein the lower end of the baffle has a radius of curvature which corresponds to the radius of curvature of the clarifier tank.
8. The density current baffle as claimed in claim 1 , wherein said baffle comprises a plurality of said first baffle portions coupled end to end around the circumference of said tank wall and wherein said baffle further comprises a plurality of downwardly sloping panel members coupled end to end around the circumference of said tank wall.
9. The density current baffle as claimed in claim 1 , wherein a lower edge of said downwardly sloping panel member includes a connection flange for coupling with a corresponding connection flange located on said upper end of said first baffle portion.
