Problems solved by technology

Moreover, the cryogenic freezing process of the prior art alone is more expensive than the method of the present invention, and the decomposition of polymer waste carried out after this cryogenic freezing process will simultaneously decompose in the example of used tires and mix the different Hard and soft rubber and its reinforcement elements such as metal, thus cross-contaminating and reducing the quality of the resulting rubber powder output, unlike the alternative of the present invention to treat different hard and soft rubber inside the tire and simultaneously remove it from e.g. metal, etc. Reinforcement elements are separated differently

Embodiment Construction

[0186] figure 1 An embodiment of a waste treatment device is illustrated having two distinct compartments made of or coated with a material resistant to the corrosive media used in the process. The reaction chamber comprises a hermetically sealable housing 1 and a screen 2 . In this embodiment the screen 2 is movable and can be moved into the hermetically sealable housing 1 . In this embodiment polymer waste is loaded into the screen 2 through an open port eg at the top of the screen 2 before the screen 2 is moved into the hermetically sealable housing 1 . The initial deformation of the polymer waste can be done outside or inside the screen 2 before the corrosive medium is applied inside the shell 1 . When loaded with initially deformed polymer waste, the screen 2 is positioned inside the housing 1, which is then hermetically sealed. The corrosive medium can then be circulated in the hermetically sealable housing 1 , wherein the corrosive medium diffuses through the screen...

Abstract

The present invention relates generally to polymeric waste processing. More particularly, the present invention relates to processing of polymeric waste which may be associated with elements such as non-polymeric material or metals. In a specific embodiment the method includes the steps of (1) loading preliminarily deformed waste into a reaction chamber, (2) applying an aggressive medium to the waste for a time sufficient to convert the one or more polymers to fragments, and separate one of more polymers from their associated elements, and (3) subjecting the products of step (2) to mechanical separation of the associated elements from the polymer fragments. The present invention is particularly useful for the processing of tyres including preliminarily deformed tyre segments or shredded tyre waste.

Description

technical field [0001] The present invention generally relates to polymer waste treatment. More specifically, the present invention relates to the treatment of polymer waste that may be associated with non-polymer materials or metals. [0002] In a specific embodiment, the present invention relates to polymer waste incorporating metal reinforcement, such as used tires, conveyor belts, respiratory equipment, and the like. The invention also relates to a waste treatment device and a method for treating polymer waste. [0003] While it will be convenient to describe the invention with reference to a partial tire breakdown process, the invention is not limited to this application and may be used with other types of polymer waste to provide a product that can then be used in other applications. Background technique [0004] The discussion throughout this specification is due to the inventor's recognition and / or the inventor's identification of problems in some related technical...
