Abstract

An apparatus for recycling synthetic thermoplastic waste material combining heretofore multiple stage processing steps in a single stage shredder grinder pulverizer device. The apparatus has multiple interchangeable material processing blade sets on respective effacing engageable rotating and fixed blade mounts within a cooled material infeed and blade containment enclosure with multiple vacuum outlet ports and communicating vacuum ducts to draw off and transport processed material therefrom for separation and classification, as required. Each replaceable interchangeable processing blade set includes registerable shredding and grinding blades and annular pulverizing blade sets on fixed and movable mediums for progressive processing of waste material into uniform recyclable material.

Claims

1. A convertible plastics processor apparatus for recycling material comprises,

a single stage shredder, grinder, pulverizer having a housing defining an enclosure,

a first multi-blade set on a rotating support disk in said enclosure in communication with a drive motor,

a second fixed multi-blade bed set mounted in said enclosure effacing said first blade set,

a top material inlet portal and dual oppositely disposed ducted vacuum top material outlet openings in said enclosure,

a centrifugal separator in communication with said ducted vacuum outlets and a source of vacuum,

a classifier in communication with said centrifugal separator,

cooling means on said enclosure and a remote source of cooling media in communication therewith,

said single stage shredder, grinder, pulverizer and said drive motor movable from a first vertical infeed position to a second horizontal product infeed position.

2. The convertible plastic processor apparatus set forth in claim 1 wherein said first and second multi-blade sets include respectively,

a continuous perimeter segmented annular blade band defining a central infeed area,

primary linear shredding and grinding defined blades within said infeed area aligned for progressive intermeshing with said second fixed bed blade sets.

3. The convertible plastic processor apparatus set forth in claim 1 wherein said second fixed multi-blade bed set is secured to a removable closure lid on said enclosure housing.

4. The convertible plastic processing apparatus set forth in claim 1 wherein said source of vacuum comprises,

a blower in communication with said centrifugal separator.

5. The convertible plastic processor apparatus set forth in claim 1 wherein said classifier includes,

multiple screens in aligned spaced orientation with one another and of varying screen mesh dimensions.

6. The convertible plastic processor apparatus set forth in claim 1 wherein said drive motor is secured to a mounting frame having aligned pivots for vertical to horizontal motor orientation.

7. The convertible plastic processor apparatus set forth in claim 1 wherein said cooling means on said blade enclosure comprises, a cooling coil around said blade enclosure, fluid chiller in communication with said cooling coil.

8. The convertible plastic processor apparatus set forth in claim 2 wherein said continuous perimeter edge segments annular blade band segments define wedging slots there between, locking wedge bars registerable within said slots.

9. The convertible plastic processing apparatus set forth in claim 2 wherein said perimeter annular blade band segments have a plurality of spaced parallel radial tapered milled blade edges.

10. The convertible plastic processing apparatus set forth in claim 2 wherein said linear shredding grinding blades have saw tooth knife edges.

11. The convertible plastic processor apparatus set forth in claim 6 wherein said drive motor and said single stage shredder grinder pulverizer in horizontal infeed product position further comprises, a horizontal product infeed assembly having a guide and material transfer means in communication therewith.

12. A first and second effacing blade sets for a convertible plastic recycling processor apparatus,

said first blade set comprises,

an annular blade band having multiple interchangeable blade segments on a rotating support disk and a multiple of elongated upstanding blades having replaceable multiple teeth inserts,

said second blade set comprising a fixed annular blade having multiple arcuate interchangeable blade segment and an elongated upstanding blade having replaceable teeth inserts thereon.

13. The first and second effacing blade sets set forth in claim 12 wherein said first and second blade sets annular blade bands interchangeable arcuate blade sections have multiple spaced parallel upstanding radial knife edges extending therefrom.

14. The first and second effacing blade sets for a convertible plastic recycling processor set forth in claim 12 wherein said first and second blade sets elongated upstanding blades multiple teeth inserts are of a saw tooth knife edge configuration and in aligned effacing progressive mesh orientation with one another.
