PL PL PL PL PL PL PL PLThe subject of the invention is a device for thermal pre-treatment of thermoplastic industrial waste and thermoplastic household waste or plastic waste, which has previously been crushed for this purpose into recyclable particles. Due to the constantly increasing pollution of the human environment, the pre-treatment and reuse of waste and hoses of any type is becoming more and more difficult. The difficulties here lie in separating the individual components of the network according to their type. It is particularly difficult if the plastic parts contained in the waste are to be separated from the waste and The main problem is the state of their reuse. For example, BFN patent no. 2061574 describes the separation of paper, textiles, glass, and metals from waste and manual sorting of the remaining residue into plastics and a part, predominantly organic, components. The plastics are then crushed, thermally treated, and finally processed into plastic products, while non-recyclable plastics are introduced as filler material into plastic products. This method ensures the complete reuse of plastics, but on the other hand, it is relatively labor-intensive. It is particularly difficult to hire workers to sort waste. manually. It is known from the description of the German patent no. 2107268 that before shredding the plastic parts, sorting on the principle of displacement is carried out, granulating the extracted plastics and then, if possible, injecting them into new plastic parts. This method leads to almost pure plastic parts from a given type of plastic, but it has the disadvantage that a significant amount of pressure is necessary for control. It is also known from the description of the German patent no. 214531Q< that shredding plastic waste and enveloping its parts with a binding agent, for example, a cement mixture or water glass, and then using these encapsulated parts as a material for filling and insulating ready-made building prefabricated elements. Using this method, it is relatively easy to use the required amount of plastic, but the condition is that the plastic waste is free from other types of waste. Moreover, plastics prepared in this way are only suitable for use in limited quantities. The aim of the invention is to design a device by which both industrial plastic waste and household plastic waste can be easily and efficiently compressed and formed for economic use. The problem, according to the invention, is solved by the device being a press with a (crushing) roller and having a driven rotating roller. placed in the machine body, wherein the roller and the machine body form a narrowing gap and form at least one crushing gap on the circumference of the roller, wherein in the direction of rotation of the roller, just before the charging hopper, there is a discharge gap with an adjustable scraper. The width of the crushing gap is adjustable, and the scraper is automatically adjustable. The machine body is heated, while the roller is cooled and/or heated. The device according to the invention makes it possible to pre-process household and industrial waste containing plastics or plastic waste, wherein without adding other binding agents, thermosets, old car tires, minerals, metals, wood, etc., they are pre-processed by means of pressure and heat. and are plasticized. It is obvious that waste can also be processed by adding cold-hardening or multi-component binders. In the machine, or in the crushing nip of the machine, very high pressures can be achieved according to the invention, so that the pre-treated materials to be compressed are optimally crushed under the action of the high pressures and bonded with a thermoplastic or other binder. In the case of pre-treated materials that are moist or are residues of fuels, the steam from the charged material is pressed out. Due to the high pressures generated in the pre-treated material, the pressed material is free from air bubbles. The subject of the invention is illustrated in The example of the embodiment in the drawing, which shows a diagram of a device for thermal pre-treatment of thermoplastic industrial and household waste, or plastic waste, in cross-section. The device basically consists of a cylindrical machine body 9 and an opening arranged horizontally in it, and an eccentrically mounted roller 10 in the opening. The machine body 9 is covered with a cover plate 3, which is provided with a charging opening. The charging opening in the plate 3 is connected to a corresponding opening in the machine body 9, directed downwards, and to an upward-directed charging hopper 1. In the direction of rotation of the roller 10, indicated by the arrow in the drawing, there is a slot 4 in the charging opening. inlet, which narrows to the crushing gap 6. In the vertical direction downwards from the crushing gap 6, the crusher 7 is adjustable by means of an adjusting screw 11. By adjusting the adjustable snub 11, the crushing gap can be adapted to the type of pre-processed material. Behind the first crushing gap, in the circulation direction, there is a chamber 8. Further in the circulation direction, above it, there is another crushing gap 6' with a V-shaped crusher and a second chamber 8'. Behind the chamber 8' is an unloading gap 12. Between the unloading gap 12 and the charging opening, there is an adjustable crusher 5' and a fixed scraper 5'. The adjustable scraper 5' can be adjusted The material is fed to the feed hopper 1 from a nearby crushing device to the material to be pre-treated in the device. The heat generated during the crushing of the material is used to evaporate water and other liquids, and the remaining heat is used to heat the thermoplastics in the device. After passing through the feed hopper 1, the material flows into the intake slot 4 and the crushing slot 6, where the thermoplastic is melted as a result of pressure and, in this case, additional heating, whereby, due to the high pressure, the vapors that occur escape upwards through the hopper 1. 30 Beyond the narrowest narrowing of the crushing gap 6, behind the crusher 7, the material passes into the chamber 8, where it expands and homogenizes. This process is repeated at the second crushing gap 6', located in the direction of rotation of the roller 10, the next crushing gap 35, the V-shaped crusher, and the chamber 8'. Behind the chamber 8', the material flows through the narrowing in the discharge gap 12, where the air inclusions in the pre-treated material are further reduced and where the material is further processed. Thanks to the crushers 5, 5' located above the discharge gap 12, the surface of the roller 10 can be scraped to any desired layer thickness. The remaining molten layer of plastic behind the scrapers 5, 5' on the surface of the roller 10 is formed. The plastic helps to introduce new material through the hopper 1 into the intake slot 4. If it is necessary to support the heating of the thermoplastic plastic, the machine body 9 should be heated by means of a heater 13, marked with a dashed line in the drawing. The roller 10 can be heated and/or cooled. 55 Patent claims 1.
