Abstract

A tank for transporting liquids, having a baffle system for control of liquid surges produced by acceleration of the tank in transit. Large cylindrical hollow baffles, parallel to the longitudinal tank axis, are mounted between transverse support partitions, the entire assembly being rigidly attached to the walls of the tank vessel. Small relief holes in the cylindrical baffles allow the liquid level in the baffles to change as the tank is filled or drained. Transverse liquid surges are controlled by the cylindrical baffles, which prevent surging of the liquid contained within the baffles, while deflecting and dissipating wave motion and surges of liquid outside the baffles. Longitudinal surges are controlled by the transverse support partitions. The configuration of cylindrical baffles and transverse partitions serves to enhance the mechanical strength of the tank, while minimizing the portion of the interior volume occupied by baffle or partition material, in comparision with some other baffle configurations which are effective in controlling surging.

Dependent claims

A tank for transporting liquids, comprising:

(a) a tank vessel for holding the liquid, having a principal longitudinal axis;
(b) baffle support means, rigidly attached to the interior walls of said tank vessel, for holding at least one baffle in fixed position within said tank vessel;
(c) at least one baffle, rigidly attached to said baffle support means, with the principal axis of said baffle being essentially parallel to the longitudinal axis of said tank vessel, said baffle being hollow and of such size that the total interior volume of said baffle or baffles is a significant portion of the interior volume of said tank vessel, said baffle having a plurality of holes in its surface, of total aperture area small in relation to the surface area of said baffle, said baffle having an outer wall each transverse cross section of which is a smooth continuous curve, convex outward along each horizontal radius of the transverse cross section of said baffle.
