Abstract
A rotary retort has an open discharge end located within a furnace. An axle assembly extends into the discharge end to support it for rotation in the furnace.
Claims31
A discharge end structure for a rotary retort, comprising a rotatable casing, having a hollow interior and a pair of open ends;
- transporting means disposed within said casing and rotatable therewith for transporting workpieces through said casing from one end to the other end in response to the rotation of said casing;
- and supporting means disposed within said casing and directly cooperating with said transporting means for supporting said casing for rotation about a longitudinal axis thereof extending from said one end to said other end, whereby workpieces are dischargeable directly from said other end of said casing.
A rotary retort comprising, a rotatable casing having a first end and a second end, said second end being open;
- transporting means disposed within said casing and rotatable therewith for transporting workpieces through said casing from said first end to said second end;
- and supporting means extending into said second end of said casing and directly cooperating with said transporting means for supporting said casing for rotation about a longitudinal axis thereof extending from said first end to said second end, whereby workpieces are dischargeable directly from said second end of said casing.
In combination, a furnace having a housing, first bearing means positioned externally of said housing adjacent one end thereof, and second bearing means positioned externally of said housing adjacent the opposite end thereof;
- and a retort mounted for rotation relative to said furnace, said retort including a first cylindrical member, having a hollow interior, an outer circumferential surface, an inner circumferential surface and a pair of open ends, one end of said first cylindrical member being disposed within said furnace and the other end of said first cylindrical member being disposed externally of said furnace and supported for rotation by said first bearing means, a first helical flight disposed within said first cylindrical member, a second cylindrical member disposed within said furnace and having an outer circumferential surface, an inner circumferential surface, a hollow interior, and a pair of open ends, one end of said second cylindrical member being attached to said one end of said first cylindrical member in coaxial relationship therewith, a third cylindrical member disposed within said second cylindrical member in coaxial relationship therewith, said third cylindrical member being supported for rotation by said second bearing means and having an outer circumferential surface, a second helical flight disposed within said second cylindrical member between said second cylindrical member and said third cylindrical member, said second helical flight being cooperatively positioned adjacent said first helical flight and cooperating with said third cylindrical member to support said second cylindrical member for rotation about a longitudinal axis thereof extending from said one end of said second cylindrical member to the other end thereof.
A method of making a rotary retort discharge end structure including a first cylindrical member, having a hollow interior and a pair of open ends, a second cylindrical member disposed within said first cylindrical member in coaxial relationship therewith, and a helical flight disposed within said first cylindrical member between said first cylindrical member and said second cylindrical member, said helical flight being fixedly connected to said first and second cylindrical members, comprising the step of forming said helical flight monolithically with said first and second cylindrical members.
A method of making a rotary retort, including a first cylindrical member having a hollow interior, a first helical flight disposed therein and an open end, comprising the steps of providing a discharge end structure including a second cylindrical member, having a hollow interior and a pair of open ends, a third cylindrical member disposed within said second cylindrical member in coaxial relationship therewith, and a second helical flight disposed within said second cylindrical member between said second cylindrical member and said third cylindrical member, said second helical flight being fixedly connected to said second and third cylindrical members;
- welding one end of said second cylindrical member to said open end of said first cylindrical member;
- providing access to said interiors of said first and second cylindrical members;
- and welding said first helical flight to said second helical flight from said interiors of said first and second cylindrical members.
