Heating apparatus and anti-ignition re-useable bladder
The invention concerns a heating apparatus for recycling metal work pieces such as pipes, stacks, tanks and chutes which are lined and/or coated with materials such as rubber, neoprene, polyurethane or plastic. The heating apparatus applies heat to metal work piece to the point where the adhesive bond between the metal work piece and the rubber, neoprene, polyurethane or plastic is broken. An anti-ignition re-usable bladder is fitted inside a metal work piece to prevent ignition of the liner and/or coating and eliminate or significantly reduce the release of gases from the liner and/or coating during the heating process.
1 . A heating apparatus for recycling metal work pieces such as pipes, stacks, tanks and chutes which are lined or coated with materials such as rubber, neoprene, polyurethane plastic or any non-metallic material on the inner surface(s), the heating apparatus surrounds the metal work piece, a space separates an inside surface of the heating apparatus and an outside surface of the metal work piece so as to clear the metal work piece and any obstacles on the metal work piece, wherein as the heating apparatus moves longitudinally over the metal work piece, the heating apparatus heats the metal work piece to the point where an adhesive bond between the metal work piece and the rubber, neoprene, polyurethane, plastic or non-metallic material is broken, the heating apparatus supplying a controlled, uniform and adjustable heat source to the outside surface of the metal work piece, the heating apparatus comprising:
a minimum of two sections connected together with a minimum of one hinge and a minimum of one connector, shrouded burners, wheels or rollers, a minimum of one lifting lug, a minimum of one sensor, and a minimum of one winching device.
2 . The heating apparatus according to claim 1 , wherein the heating apparatus comprises a minimum of two sections which are connected with a minimum of one hinge and a minimum of one connector allowing the heating apparatus to be opened and closed for easy installation and removal.
3 . The heating apparatus according to claim 1 , wherein the heating apparatus sections can be round, square or rectangular in shape.
4 . The heating apparatus according to claim 1 , wherein the heating apparatus is self-propelled, pulled or pushed across the metal work piece at a speed which is variable and partially or fully automated.
5 . The heating apparatus according to claim 1 , wherein the heating apparatus is fitted with a minimum of one counter weight.
6 . The heating apparatus according to claim 1 , wherein the heating apparatus is fitted with a minimum of one sensor such as temperature, speed, movement, or an emergency gas shut off sensor, or a combination thereof.
7 . The heating apparatus according to claim 1 , wherein the wheels or rollers are adjustable up and down.
8 . A system for recycling metal work pieces comprising the heating apparatus of claim 1 and an anti-ignition re-usable bladder, comprising:
a flexible, anti-ignition, heat resistant, fire resistant and non-absorbent material which is fitted with a minimum of one fitting.
9 . The anti-ignition re-usable bladder according to claim 8 , wherein a minimum of one anti-ignition re-usable bladder is fitted inside a metal workpiece which is lined or coated on the inner surface, the anti-ignition re-useable bladder is inflated inside the metal work piece and ultimately takes on the inner shape of the metal work piece, the outside surface of the anti-ignition re-useable bladder is firmly pressed against the surface of the liner or coating, and capable of expanding and taking on the shape of the internal metal work piece and capable of holding and maintaining a pressurized gas and being any length, dimension or shape, the anti-ignition re-usable bladder prevents ignition of the liner and/or coating and eliminates or significantly reduces the release of gases and smoke from the liner and/or coating when exposed to heat.
10 . A system for recycling metal work pieces comprising the heating apparatus of claim 1 and an anti-ignition re-usable bladder, comprising:
a flexible, anti-ignition, heat resistant, fire resistant and non-absorbent material which is fitted with a minimum of one fitting and having one side, top or bottom which is significantly flat.
11 . The anti-ignition re-usable bladder according to claim 10 , wherein a minimum of one anti-ignition re-usable bladder is fitted inside a metal workpiece which is lined or coated on the inner surface, the anti-ignition re-useable bladder is inflated inside the metal work piece and ultimately takes on the inner shape of the metal work piece, the outside surface of the anti-ignition re-useable bladder is firmly pressed against the surface of the liner or coating, and capable of expanding and taking on the shape of the internal metal work piece and capable of holding and maintaining a pressurized gas and being any length, dimension or shape, the anti-ignition re-usable bladder prevents ignition of the liner and/or coating and eliminates or significantly reduces the release of gases and smoke from the liner and/or coating when exposed to heat.
