Abstract
An improved rotary filter is cylindrical in shape, and operates by vacuum suction or otherwise to withdraw fluids from a substance exposed to the outer area of the device, drawing said fluids into the filter to be pumped out to a suitable reservoir. It includes an inner cylindrical surface having attached thereon a plurality of selectively spaced support structures which extend longitudinally along the inner cylinder. Said support structures are covered with a plastic covering adapted to receive a filtering medium which forms the outer circumference of the rotary filter. In one embodiment the plastic covers are grooved to receive a spirally wound wire to further support said filtering medium.
Claims12
In a rotary filter, the combination of:
- a. An inner cylindrical surface;
- b. A plurality of support structures selectively spaced apart and extending longitudinally along said surface;
- c. Plastic coverings fitted over said support structures;
- d. A filter medium extending around the outer circumference formed by said support structures and resting against said support structures;
- and,
- e. Means for holding said filter medium firmly against said support structures.
A method of refinishing a rotary filter of the type consisting of a plurality of metallic support structures selectively located on an inner cylindrical surface, wire spirally wound around the filter and fitting within grooves in said support structures, and a filter medium extending around the outer circumference formed by said wire, consisting of the following steps:
- a. Removing the filter medium to expose the wire wound around the filter;
- b. Removing the wire wound around the filter to expose the support structures;
- c. Placing a plastic cover of predetermined size over each of said support structures;
- d. Placing a new filter medium around said rotary filter and resting on said plastic covers;
- and,
- e. Securing the filter medium against said support structures.
