Definitions

  • the present invention relates to a process of reuse of plastic waste based on the production of agglomerates in the form of layers or blocks, by total or partial replacement of components customary in the agglomerates by plastic waste.
  • the relevance of the invention in addition to residing in itself, originates in the projection of the invention to solve a problem of increasing dimensions such as plastic waste, whose presence in the environment has a life that ranges from around 100 and 2000 years, so they are considered as the 2nd most important polluting the environment.
  • plastic waste is PET containers used with a plurality of liquid substances, such as beverages, oils, chemicals, etc.
  • SUBSTITUTE SHEET Referring to this specific type of waste, such as PET (ethylene polyterephthalate), which is increasingly used in packaging, it should be noted, for example, the existence of firms capable of producing really high quantities. According to some data considered, corresponding to the year 1997, in relation to certain areas of South America, it was found that a single Venezuelan company was able to generate an amount of the order of 20,000 tons, representing this figure around 10% of the total market South American.
  • each PET container has an average weight of 12 grams and a volume of 1 liter. Therefore, the 20,000 tons equals 16 million cubic meters, which gives a clear idea of the physical pollution it represents.
  • the present invention develops a process that involves a phase of preparation of plastic waste, for its subsequent application in construction or other sectors.
  • the invention is especially applicable, although not exclusively, to the realization of blocks and / or bearing layers for use in paving operations and the like.
  • SUBSTITUTE SHEET (RULE 26) Preparation implies a succession of stages in which a compaction of plastic waste is distinguished, in order to provide them with laminar forms, which in turn facilitates storage.
  • a phase of scaling of the waste is carried out, with the preferential intervention of knife mills (although special machines can also be developed for their size for such purposes), advantageously graduated to obtain scales with the appropriate dimensions for the subsequent application to which they are intended.
  • the application although it is of general order to obtain substances of preferential use in construction, it can be oriented, preferably, to two main applications: pavement and blocks, in the mixtures for revocation and replacement of fillings in mezzanines .
  • the plastic waste scales partially or totally replace the arid elements of said mixtures, such as gravel, stone, ballast, sand, etc., matching or exceeding the mechanical properties contributed by the latter.
  • an unexpectedly novel aspect found by the invention does not lie primarily in the substitution of gravel, but in the ability offered by this invention to reuse large amounts of plastic waste, thus avoiding pollution caused, not only in quantity, but in processes of plastic removal by incineration or discharge into the seas.
  • an unexpectedly novel aspect found by the invention does not lie primarily in the substitution of gravel, but in the ability offered by this invention to reuse large amounts of plastic waste, thus avoiding pollution caused, not only in quantity, but in processes of plastic removal by incineration or discharge into the seas.
  • the invention provides effective solutions with which it is possible to remedy the currently existing problems, allowing an appropriate reuse of waste of the type considered.
  • the stages on which this procedure is based mainly consist of:
  • Said containers are provided inside a mechanism that includes a series of compressor rollers, whose operation is generated by the actuation of pulleys or gears activated by electrical energy or mechanically by means of a lever or crank located on the outside of the container.
  • Figures 1-3 of the drawings Examples of some types of containers that can be advantageously used in the process of the invention, and of their associated mechanisms, have been represented in Figures 1-3 of the drawings, in a simple, schematic and purely illustrative manner.
  • a container has been shown and on it, a representation of the respective mechanism it incorporates. If these representations are taken into account, a container (1) can be seen in Figure 1, suitably sized from a minimum preconceived capacity, whose upper part has been shaped so that its mouth narrows downwards, to the move inwards, to constitute a funnel-like portion
  • rollers (3) Faced with the lower outlet of the portion (2), the arrangement of rollers (3) is provided, horizontally extended, parallel to each other and separated by a predetermined distance, by means of which they press the waste introduced by the mouth of the container , this dragging action of the waste being favored by the movement of at least one of the rollers (3), which is driven by an electric motor (4).
  • a device (5) for feeding the motor which can be operated due to the lifting or opening of the cover (6) for closing the opening
  • Figure 2 provides an arrangement similar to Figure 1, except that in this case, the electric motor has been dispensed with, so that the dragging action of the waste introduced by the upper part of the portion
  • the third option, represented in Figure 3, follows the same teachings above, although, in this case, the arrangement adopted by the rollers (3 ") is vertical, and the access area inside the container of compacted waste, it consists of a passage portion (8) located between, and below, said rollers, the drive of the drive roller is preferably carried out by means of a crank (7 '), and the configuration of this roller of Dragging is eccentric, so that after maximum compression, it provides greater separation that allows compacted debris to fall into the container (1.)
  • This arrangement is schematically represented at the top of Figure 3.
  • At least one of the rollers provided in the containers (1) will be of the spiral spindle type, in order to provide increased tightening on the waste considered.
  • the mills used to transform the sheets into scales can be of several known types, including those that have cutting blades associated with the rotating axis of an engine, angularly equidistant from said driving axis, as well as the mills of hammers or balls such as those used to hit the stone in order to form different gravel sizes, or even those that follow a system known as "jet", in which central blades project the material against the walls of the accommodation in which they are enclosed, so that the. impact generated by the centrifugal force imparted to the matter, causes it to break and scale.
  • the procedure includes the stage of mixing the scales obtained in stage c) with other usual ingredients for the preparation of building materials.
  • step d) intended for the manufacture of the tread layer of any pavement, the following components are involved in the constituent mixing operation of step d) above:
  • PET scale 42% by weight
  • a combination of this type allows to build a rolling layer with an average of 7 cm in height, through which 9.8 square meters can be covered. This gives a clear idea of the ability to eliminate the contamination allowed by the process of the present invention.
  • 70 km of road will consume approximately 20,000 tons of waste.
  • 700 km of 7 cm high and 7 meters wide tread or cover will allow all PET waste from South America to be absorbed. This eliminates the problem posed by this type of waste.
  • the proportions expressed are referred to the total weight of the combination, and constitute only an example susceptible to variation depending on the factors that concur in each specific application.

Abstract

L'invention concerne un procédé permettant d'élaborer des agglomérats destinés à être utilisés comme revêtement de chaussée, aussi bien sous forme de couche ou de couverture de roulement que sous forme de blocs, en utilisant des résidus plastiques du type PET en remplacement d'autres composants non agglomérants. Pour l'essentiel, les étapes du procédé consistent à recueillir et à compacter les résidus plastiques dans des conteneurs conçus à cet effet, à écailler ces résidus avec l'utilisation de moulins pourvus de mécanismes de régulation de la taille des écailles, et à mélanger différentes substances de l'agglomérat avec ces résidus plastiques écaillés.
