Abstract
The invention relates to an apparatus for the conversion of plastic waste into usable material, in which a number of rotating knives are arranged at the bottom of a cylindrical space receiving the plastic waste, and in which by deflecting means arranged along the periphery of said space, the plastic waste, while being cut and circulated by the rotating knives, is directed back into the path of said rotating knives.
Claims12
In an apparatus for the conversion of plastic waste into usable material, means including an upright wall forming a cylindrical working space, at least one rotatable knife arranged at the bottom of said space coaxial therewith, and counter action tools arranged along the wall at the bottom of said space, facing said knife, means above said knife at the top of said space for charging said space with plastic waste;
- and elongted means attached to said wall at a predetermined height substantially above, and separated from said counter action tools, and projecting from said wall at a distance small against the radius of said wall;
- said elongated means extending at said height circumferentially and in the direction of its elongation, at least along a portion of the periphery of said wall;
- and while said waste is being cut and circulated by said knife and thereby rising along the wall, reflecting said rising waste at said height back toward the path of said knife.
Apparatus for the conversion of plastic waste into a flowing granulate, comprising a cylindrical container with inlet and outlet;
- and in its lower portion arranged around the axis of the container, a beating comminution tool with radial arms circulating to comminute, heat and agglomerate the waste, counter action tools being arranged along the wall of the container, facing said beating comminution tool;
- and consisting of a number of plane elements with sides angularly joined to each other, forming at least one sheet-like structure with a polygon-like cross section;
- each element extending along the circumference of the wall as well as upward and downward from a center point, thus forming a plane surface perpendicular to the radial arms when passing the center point, and also forming an acute angle with the circumference so that the plastic waste driven by the circulating tool against a plane element will be guided back into the path of said circulating tool.
In an apparatus for the conversion of plastic waste into a flowing granulate, a substantially cylindrical upright container having inlet and outlet, and in its bottom space coaxial with said container, a beating comminution tool arranged to circulate for the comminution, heating and agglomeration of the waste;
- and counter action tools arranged along the wall of said container within the operating range of the beating comminution tool thereby impeding the movement of said waste along the periphery of the bottom of the wall while permitting its rise upward along the wall, and at least one elongated element attached to the inside of the container wall in a position at a predetermined height substantially above and separate from said counter action tools;
- said elongated element having a surface facing downward and extending peripherally along a predetermined portion of said wall, and projecting from said wall to the inside of said container for a distance which is small against the radius of said wall, thereby preventing the waste from rising upward along the wall beyond said predetermined height.
