Abstract
A curing oven provides a structure which is supportive such that structural members extending the axial length of the oven are not necessary. Additionally, the curing oven provides structures which extend transverse to the axial length of the oven but do not extend through the walls of the oven. Thus, conductive heat transfer is limited and reduced.
Claims16
A curing oven, comprising:
- a plurality of modules having a substantially cylindrical shape including a substantially circular cross-section defined by an outer wall;
- an inner wall spaced radially inward from said outer wall;
- an insulation disposed between said outer wall and said inner wall;
- a connecting ring disposed between adjacent modules having said substantially cylindrical shape of said plurality of modules and retaining said adjacent modules together in an axial direction, said connecting ring spaced radially inwardly from said outer wall;
- a conveyor support member extending chordally across a lower portion of each of said modules for support of a conveyor above;
- support mounts spaced apart axially along an axial length of said oven;
- a plurality of ducts extending arcuately within at least one module adjacent to said inner wall.
4 more elements
A curing oven, comprising:
- at least one module of generally hollow cylindrical shape having a first end and a second end;
- said at least one module having an outer wall and an inner wall and a connecting ring at at least one end which connects axially to an adjacent module, said connecting ring spaced radially inwardly from said outer wall, said adjacent module also having a generally hollow cylindrical shape;
- at least one stiffener ring extending about said inner wall;
- an insulation retainer disposed radially outward of said inner wall and an insulation layer disposed between said inner wall and said insulation retainer;
- and,
- an air gap located between said insulation retainer and said outer wall.
3 more elements
A curing oven, comprising:
- a first module having a substantially circular cross-section and extending axially to form a substantially cylindrical shape;
- a second module having a substantially circular cross-section and extending axially to form a substantially cylindrical shape;
- each of said modules further comprising:
- an outer wall formed of a plurality of panels;
- an insulation layer disposed radially inward of said outer wall and captured between a circular insulation retainer and an inner wall;
- a connecting ring spaced radially inward of said outer wall and connecting said first and second modules in an axial direction;
- an air gap formed between said insulation layer and said outer wall;
- a plurality of stiffener rings spaced apart axially;
- and,
- a support mount positioned below said modules, a connection between said support mount and at least one of said modules having a thermal break.
