Abstract
A tank includes a cone-shaped wall formed of steel and attached between a first dome-shaped surface formed of steel and a second dome-shaped surface formed of steel. The cone-shaped wall attached between the first dome-shaped surface and the second dome-shaped surface defines an oval-shape void of angled corners on the inside surface of tank such that, when a product contained in the tank is displaced, the product is displaced in a torus shaped vortex between the first dome-shaped surface and the second dome-shaped surface.
Claims20
A tank comprising:
- a first dome-shaped surface being formed of steel and having a perimeter defining a first diameter;
- a second dome-shaped surface opposite the first dome-shaped surface, the second dome-shaped surface being formed of steel and having a perimeter defining a second diameter larger than the first diameter of the first dome-shaped surface;
- and
- a cone-shaped wall formed of the steel and having a top perimeter opposite a bottom perimeter,
- wherein:
- the top perimeter of the wall is attached to the perimeter of the first dome-shaped surface and defines a top interface void of angled corners on an inside surface of the tank,
- the bottom perimeter of the wall is attached to the perimeter of the second dome-shaped surface and defines a bottom interface void of angled corners on the inside surface of tank, and
- the wall attached to the first dome-shaped surface and the second dome-shaped surface defines an oval-shape void of angled corners on the inside surface of tank such that, when a product contained in the tank is displaced, the product is displaced in a torus shaped vortex between the first dome-shaped surface and the second dome-shaped surface.

A tank comprising:
- a first dome-shaped surface being formed of steel and having a perimeter defining a first diameter;
- a second dome-shaped surface opposite the first dome-shaped surface, the second dome-shaped surface being formed of the steel and having a perimeter defining a second diameter larger than the first diameter of the first dome-shaped surface;
- a first wall portion formed of the steel and attached to a second wall portion formed of the steel, the first wall portion attached to the second wall portion defining a seam having an elliptical shape, the first wall portion having a top perimeter and the second wall portion having a bottom perimeter opposite the top perimeter,
- wherein:
- the top perimeter of the first wall portion is attached to the perimeter of the first dome-shaped surface,
- the bottom perimeter of the second wall portion is attached to the perimeter of the second dome-shaped surface, and
- the first wall portion attached to the first dome-shaped surface and the second wall portion attached to the second dome-shaped surface defines an oval-shape void of angled corners on the inside surface of tank such that, when a product contained in the tank is displaced, the product is displaced in a torus shaped vortex between the first dome-shaped surface and the second dome-shaped surface.
