Abstract

The present invention refers to a process for recycling tyres and plastic products by using a chemical pre-treatment, and a cryogenic cooling system for subsequently originating the authentic disintegration of the pneumatic components without losing their physical-chemical properties due to the use of ozone; besides offering the use of affordable facilities, the system is environmentally friendly. The present process includes the advantage of saving power compared to shearing and milling processes where the plastic material reuse is minimum as it is only used for concrete and asphalt mixtures.

Description

"PROCESS FOR THE RECYCLING OF TIRES AND PLASTICS." TECHNICAL FIELD OF THE INVENTION The present invention has its field of application in the mechanical and chemical area since it provides a process for recycling tires and plastics.
BACKGROUND OF THE INVENTION Currently the technology used in the recycling of tires and plastic products, corresponds to processes of pyrolysis, mechanical disintegration or chemical solvents.
In the state of the art there are news of machines and processes for the treatment of tires or plastics which use pyrolysis or thermolysis for the treatment of tires these processes have been sanctioned by different organisms the use and burning in the pyrolysis furnaces of the cement factories. US 5,524,838, 1996/06/11, US 4,025,990 1977/05/31, US 42J3294 1981/06/16 describe processes by means of cryogenic cooling and grinding to reduce the volume of tire waste, these processes do not resolve the aspects of reuse of the product and confinement, since they lose their physical-chemical properties when being grinding of a whole, and the materials resulting from this process can not be reused in the manufacture of new tires, because there is no separation of the components.
DETAILED DESCRIPTION OF THE INVENTION The characteristic details of this novel process for recycling tires and plastics are clearly shown in the following description.
The process for recycling tires and plastics consists of the following stages: A) Classify according to their type and physical chemical conditions, the material to be recycled and which can be based on tires of all types and sizes, or plastic parts, forming homogeneous groups for processing.
B) Wash the tires or plastic materials with water under pressure.
C) Immerse in tank with a chemical solution based on kerosene or toluene tires or plastic materials at a temperature of 26 eC +/- J 9C for 4 hours.
D) Transport the tires or plastics to a first cooling tank until reaching cryogenic temperatures of -65 QC to -90 SC and achieve their vitrification.
E) Inject ozone gas into the tires, under pressure through nozzles distributed in the first cooling block, to the point of disintegration, at the end of this stage of the process the ozone gas is transferred to a second cooling tank.
F) Mechanically vibrate the raw material by means of a metal mesh located at the bottom of the first cooling tank for the separation of the metallic components. The plastic components pass through said mesh to be deposited in the bottom of the tank for its collection, the size of the particles is achieved in the following way to higher ozone gas pressure, lower temperature and longer residence time particles of sizes are obtained from 0.5cm to 2.5cm.
G) Transfer the remnants of the ozone gas remaining from the first cooling tank, to a second cooling tank where the process cycle is repeated from stage D).
For all the above, it can be said that these process characteristics have not been achieved by any technology and provides the following advantages: It is an ecological process, because it does not generate noise, dust, unpleasant odors or fumes or aggressive substances to the environment.
Process that consumes a low amount of energy compared to the processes of tearing or grinding the material.
This process allows the reuse of rubber or plastic for the manufacture of tires and the recovery of metallic fibers.
Minimizes up to 80% the volume of waste to be confined in landfills.

RE1VIND1CAC1ONES Having sufficiently described my invention, I consider as a novelty and therefore claim as my exclusive property, what is contained in the following clauses:
1. process for recycling tires and plastics is characterized because it consists of the following stages: A) Classify according to their type and physical chemical conditions, the material to be recycled which can be based on tires of all types and sizes, or plastic parts, forming homogeneous groups for processing. B) Wash the tires or plastic materials with water under pressure. C) Immerse in tank with a chemical solution based on kerosene or toluene tires or plastic materials at a temperature of 26 SC +/- 7 eC for 4 hours. D) Transport the tires or plastics to a first cooling tank until reaching cryogenic temperatures of -65 QC to -90 SC and achieve their vitrification. E) Inject ozone gas into the tires, under pressure through nozzles distributed in the first cooling tank, to the point of disintegration, at the end of this stage of the process the ozone gas is transferred to a second cooling tank. F) Mechanically vibrate the raw material by means of a metal mesh located at the bottom of the first cooling tank for the separation of the metallic components. The plastic components pass through said mesh to be deposited in the bottom of the tank for its collection, the size of the particles is achieved in the following way to higher ozone gas pressure, lower temperature and longer residence time particles of sizes are obtained from 0.5cm to 2.5cm. transfer the remaining ozone gas residues from the first cooling tank, to a second cooling tank where the process cycle is repeated from stage D).
