ABSTRACT:
The present invention provides a motor driven, helical screw conveyor having an impeller wheel at one end thereof. The screw conveyor is immersed in the liquid to be transferred and lifts the liquid so that the impeller may drive it through a first conduit and a first valve into a utilization device. The valve has three separate positions, the first of which permits delivery of a major portion of the fluid to the utilization device with a minor portion of the fluid being returned to the container via a second conduit. A second position of the first valve provides for flow of fluid from the container, through the first conduit, through the first valve and then directly back to the container via the second conduit. A third position of the valve is utilized with a flexible apron that encloses the utilization device so that when it is desired to clean the apparatus, a cleaning fluid is delivered through the first conduit to the utilization device and outwardly therefrom into the enclosing apron and then through the valve for return to the container via the second conduit. In conjunction with the closed loop cleaning system there is provided a filter that surrounds the helical screw conveyer. Initially the cleaning fluid is contained with the filter and is transported via the conveyer and the two conduits. After passing over the utilization device, the cleaning fluid is discharged onto the inside surface of the cover that supports both the conveyer and the drive motor therefor. The returned cleaning fluid is accumulated in a container and, should it be desired to pass the cleaning fluid through the conveyer and the utilization device for a second time, a valve is opened that permits the cleaning fluid to pass through the filter medium so as to be transported for a second time by the conveyer. The present invention may be used in the non-cleaning mode by inserting the helical conveyer into a paint can, for example, and by releasably clamping the cover that supports the conveyer and the drive motor therefor to the paint can. Alternatively, the present invention may be used with a separate container that includes the filter system with the helical conveyer and the cleaning fluid, the drive motor therefor and with the cover that supports both the helical conveyer and the drive motor being releasably clamped to the container. A carriage having wheels may be provided for supporting the apparatus in either modes of operation.
