Abstract
A dual purpose pump for pressure vessels comprises a piston pump disposed within a pump cylinder. The piston pump is arranged in the interior of the pressure vessel and actuatable from the outside by piston strokes for building up an increased pressure in the interior of the vessel. The pump cylinder is mounted on the vessel and projects into the interior thereof. The present invention simplifies mixing, e.g. the preparation of an emulsion, by rotatably mounting the pump cylinder about its longitudinal axis. To accomplish this, a drive mechanism may be mounted on he outside of the vessel for rotating the pump cylinder and the pump cylinder takes mixing elements along with it which project into and thereby mix the liquid during rotation.
Claims12
A dual purpose pump for pressure vessels used for mixing and spraying a liquid, comprising:
- a piston pump mounted in an interior portion of said pressure vessel;
- said piston pump including a pump cylinder projecting into said interior of said pressure vessel, said pump cylinder being rotatable about a longitudinal axis thereof;
- means for actuating said piston pump from the outside of said pressure vessel, said actuating means providing piston strokes to said piston pump for building up an increased pressure in said interior of said pressure vessel;
- drive means for rotating said pump cylinder from the outside of said pressure vessel;
- and
- a mixing element operatively connected to, and rotatable with said pump cylinder, said mixing element projecting into said liquid for mixing same.
