Abstract
A method of recycling spent filter media is disclosed. The method can include providing a cloth, the cloth being spent polymer-base filter media, removing foreign solid particles from the cloth, washing the cloth, drying the cloth and processing the dried cloth to produce polymer-base particles that can be used to produce a component. The processing of the dried cloth can include densifying and/or granulating the dried cloth. In addition, the spent cloth can have been used as metal working filtration media and the foreign solid particles removed from the cloth using a brush. In some instances, the cloth is washed using a dry cleaning process and the granulating or densifying of the cloth produces particles that can be used in an injection molding machine.
Claims13
A method of recycling spent filter media comprising:
- providing a cloth, the cloth being spent polymer-base filter media;
- rolling the spent polymer-base filer media into a roll;
- removing foreign solid particles from the roll of cloth by unrolling the cloth and passing the cloth past and in contact with a rotating brush;
- rolling the brushed cloth back into the form of a roll;
- cutting the roll of cloth into a plurality of sections;
- washing the plurality of cloth sections;
- drying the plurality of cloth sections;
- and
- processing the dried cloth to produce polymer-base particles, the particles selected from a group consisting of granules, pellets and combinations thereof, and used to produce a component.
A method of making a component out of recycled polymer-base filter media cloth, the method comprising:
- providing a cloth, the cloth being spent polymer-base filter media;
- rolling the cloth into a roll;
- removing foreign solid particles from the roll of cloth by unrolling the roll of cloth and passing the unrolled cloth between a pair of rotating brushes, the brushes mechanically removing the foreign solid particles from the cloth;
- rolling the cloth that has passed between the pair of rotating brushes back into a roll;
- cutting the roll of cloth into a plurality of sections such that a plurality of rectangular sheets of cloth are produced;
- washing the rectangular sheets of cloth;
- drying the rectangular sheets of cloth;
- processing the rectangular sheets of cloth to produce polymer particles, the particles selected from a group consisting of granules, pellets and combinations thereof and the processing selected from a group consisting of granulating and densifying;
- providing an injection molding machine;
- placing the particles of polymer into the injection molding machine;
- and
- injection molding the particles of polymer to produce a component.
