Oblasť technikyTechnical field
Vynález sa týka výtlačného zariadenia na recykláciu plastických hmôt, ktoré sa nedajú skrápať, prípadne nie sú tekuté, ktoré má výtlačný lis s výtlačným slimákom, privádzací agregát, ktorý odovzdáva východzí materiál na mechanické spracovanie plastických hmôt naplňovaný zásobnou násypkou do naplňovacej oblasti výtlačného slimáka, pričom privádzací agregát je vytvorený ako privádzací slimák.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-sprinkling or non-fluid plastic recycling extruder having a die extruder having a feed assembly that feeds a starting material for mechanical processing of plastics filled by a feed hopper into the feed region of the extruder. the feed unit is designed as a feed slug.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Výtlačné zariadenia s výtlačným lisom preberajú pevné plastické hmoty a vytláčajú ich z otvoru prevažne kontinuálne. Pritom výtlačný lis stláča materiál na mechanické spracovanie plastických hmôt, zmiešava ich, plastifikuje a homogenizuje. Podstatné konštrukčné skupiny výtlačného lisu sú výtlačné slimáky pracujúce vo valci a privádzajúce agregát, ktorý privádza materiál na mechanické spracovanie platických hmôt do výtlačného lisu.The extruders with the extruder take solid plastics and push them out of the orifice mostly continuously. The extruder presses the material for mechanical processing of plastics, mixes, plasticizes and homogenises them. Substantial extruder assemblies are extruder snails operating in a cylinder and supplying an aggregate that feeds the material for mechanical processing of platinum masses to the extruder.
Z DE 28 34 043 A je známy výtlačný lis s dvojitým slimákom, ktorý je opatrený dvojitým prívodom, pričom tiež prívod je vytvorený ako výtlačný lis, to znamená, že tiež do privádzacieho ústrojenstva sa naplňujú hmoty, ktoré sa nedajú skrápať, prípadne tekuté látky, ktoré sa tu hnutňujú a za účelom primiešavania sa privádzajú do vlastného dvojitého výtlačného lisu. Prostredníctvom takéhoto zariadenia nie je možné spracovávať skrápania schopné, prípadne nie tekuté plastické hmoty, pretože na podklade veľkého objemu takýchto látok by nebol možný bezchybný prívod prostredníctvom tohto známeho usporiadania.DE 28 34 043 A discloses a twin-screw extruder which is provided with a double inlet, the inlet also being designed as an extruder, i.e. also impregnable or liquid substances are fed into the feed device, which are moved here and fed to their own double extruder for mixing. By means of such a device it is not possible to process scraps which are capable or not of liquid plastics, because, due to the large volume of such substances, a flawless supply via this known arrangement would not be possible.
v tvare dvoch navzájom s osou výtlačného lisuin the form of two mutually with the axis of the extruder
Z AT 398 937 je známe zariadenie na plastifikáciu termoplatických plastických hmôt, pri ktorom je na vstupnom otvore upravené ústrojenstvo na rozdrvovanie rovnobežných a rovnobežne usporiadaných hriadeľov, ktoré sú opatrené väčším počtom drviacich nástrojov. Prostredníctvom tohto usporiadania sa má dosiahnuť to, že v tvare odpadu privádzaný materiál z plastickej hmoty je jednak účinne rozdrvovaný a jednak je tento rozdrvený materiál z plastickej hmoty preberaný výtlačným lisom a je prevádzaný do plastického stavu. Pri tomto riešení sú navrhnuté rôzne rýchle obiehajúce rozdrvujúce hriadele, pričom rýchlejšie sa otáčajúci hriadel vytvára zastavovacie komponenty, ktoré majú materiál z plastickej hmoty zatláčať, prípadne vyraziť v smere na slimák do závitov výtlačného slimáka.A device for plasticizing thermoplastic plastics is known from AT 398 937, in which an inlet opening is provided with a device for crushing parallel and parallel arranged shafts, which are provided with a plurality of crushing tools. By means of this arrangement, it is to be achieved that the plastic material supplied in the form of waste is, on the one hand, effectively crushed and, on the other hand, the crushed plastic material is taken over by an extruder and is transferred to a plastic state. In this solution, various rapidly circulating crushing shafts are designed, the faster rotating shafts forming stopping components which are to push the plastic material or eventually emboss it in the direction of the slug into the threads of the discharge slug.
Pokiaľ však majú materiály na mechanické spracovanie plastických hmôt privádzané do výtlačného slimáka menšiu sypnú váhu, ako sú napríklad odrezky fólií alebo vlákna alebo podobne, je prirodzene snaha odborníkov zavádzať do výtlačného slimáka väčší objem, pričom tento objem materiál na mechanické spracovanie plastických hmôt sa vo výtlačnom slímáku ďalej stláča a platifikuje.However, if the plastic processing materials fed into the extruder have a lower bulk density, such as foil or fiber shavings or the like, it is naturally desirable for those skilled in the art to introduce a larger volume into the extruder, this volume of the plastic processing material being in the extruder. then pushes and pays the slider.
Podstata vynálezuSUMMARY OF THE INVENTION
Vynález si kladie za úlohu vytvoriť zariadenie, prostredníctvom ktorého by bolo možné privádzať a stláčať tiež skrápania neschopný prípadne nie tekutý a malú sypnú váhu vykazujúci materiál na mechanické spracovanie plastických hmôt vo väčšom množstve, to znamená s vysokým objemom do výtlačného slimáka.SUMMARY OF THE INVENTION It is an object of the present invention to provide a device by means of which it is also possible to feed and compress scraps which are incapable of flowing or not having a liquid or low bulk density.
Táto úlohu, ktorá je základom vynálezu, je riešená znakovou časťou hlavného patentového nároku.This object, which is the basis of the invention, is solved by the feature of the main claim.
Výhodné usporiadania sú vysvetlená v závislých patentových nárokoch.Preferred arrangements are explained in the dependent claims.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Na obr.l je znázornený výtlačný lis 1, ktorý má poháňacie ústrojenstvo 9 a naplňovaciu oblasť 7. Do tejto naplňovacej oblasti 7 výusťuje privádzaci agregát 3, ktorý je naplňovaný zo zásobnej násypky 2, pričom tento privádzaci agregát 3 pozostáva z dvoch výhodne protibežných privádzaich slimákov 5,6^.1 shows an extruder 1 having a drive device 9 and a filling area 7. Into this filling area 7 a feed aggregate 3, which is filled from a feed hopper 2, is discharged, the feed aggregate 3 consisting of two preferably opposing feed snails. 5.6 g.
Privádzaci agregát 3 je upravený v spodnej oblasti zásobnej násypky 5 a prídavné v ňom môžu byť usporiadané pádla alebo iné premiešavacie agregáty, aby sa zabránilo vytváraniu mostíkov v skrápaní neschopnom a netekutom materiáli, ktorý je v zásobnej násypke 2, pričom sa tu v podstate jedná o fóliové kúsky, vlákna alebo podobne.The feed aggregate 3 is provided in the lower region of the feed hopper 5, and additional paddles or other agitation aggregates may be provided to prevent the formation of bridges in the dripping and non-fluid material that is present in the feed hopper 2, essentially foil pieces, fibers or the like.
Tiež privádzaci agregát 3 má odovzdávaciu oblasť 11, ktorá vyúsťuje do naplňovacej oblasti 7 výtlačného lisu 1.Also, the feed unit 3 has a transfer area 11 that opens into the feed area 7 of the extruder 1.
Z vyobrazenia na obr.2 je zrejmé, že výtlačný slimák 4 v oblasi naplňovacej oblasti 7 je pri tomto príklade uskutočnenia upravený o mieru presadenia a hlbšie ako je vyústenie privádzacieho slimáka 6. Os X-X privádzacieho slimáka 6 je znázornená na obr. 2 a os Y-Y výtlačného slimáka 4 je znázornená na obr.3 .It can be seen from FIG. 2 that the discharge slug 4 in the region of the filling region 7 is adjusted in this embodiment by a degree of offset and deeper than the opening of the feed slug 6. The X-X axis of the feed slug 6 is shown in FIG. 2 and the Y-Y axis of the discharge slug 4 is shown in FIG.
Z obr.2 je tiež zrejmé, oboch privádzacích slimákov tiež nad výtlačným slimákom ktorý zaisťuje dobré výtlačného slimáka 4 a že v oblasti vyústenia 5,6_ je nad nimi a tým 4 upravený kryt 16, odovzdávanie materiálu do tým tiež do výtlačného valca výtlačného sllimáka 4. Ďalej je tu tiež naprílad v hornom prekrytí slimákového prevádzacieho agregátu 2 a vo výtlačnom výtlačného slimáka 4 sú vytvorené drážk; zabezpečujú dobrú dopravu materiálu.It is also apparent from FIG. 2 that both feed slugs are also above the slug which provides a good slug 4 and that in the area of the outlet 5,6 there is a cover 16 over them and thereby 4, transferring the material therein also to the slug cylinder 4 Furthermore, there is also, for example, grooves formed in the upper overlap of the snail transfer unit 2 and in the discharge discharge snail 4; ensure good transport of material.
Vlastné slimákové hriadele 10 privádzacích slimákov 5 a 6_ sú v svojej odovzdávacej oblasti vytvorené demokompresívne, to znamená že majú menší priemer ako v ostatnej oblasti privádzacích slimákov 5 a 6.The actual slug shafts 10 of the feeding slugs 5 and 6 are formed in their transfer area demompressively, i.e. they have a smaller diameter than in the other area of the feeding slugs 5 and 6.
privádzací agregát 2 slimáky 5,6 vyúsťujúthe feed aggregate 2 slugs 5.6 result
Z obr.3 je zrejmé, že vytvárajúci privádzacie v oblasti naplňovacej oblasti 7 svojimi centrálnymi osami pri tomto príklade uskutočnenia nad osou Y - Y výtlačného slimáka 4, pričom ďalej je podstatná tá skutočnosť, že výtlačný slimák 4 je najmenej v oblasti naplňovacej oblastí dvojchodný alebo viacchodný. Mimoto má vytvorený výtlačný slimák 4 v oblasti naplňovacej oblasti 7 väčšie stúpanie ako v ostatných oblastiach, pričom toto stúpanie je väčšie ako 1 D, výhodne má hodnotu 1,1, - 2,5 D, pričom písmeno D označuje priemer slimáka.It can be seen from FIG. 3 that the feed lines in the region of the feed region 7 by their central axes in this embodiment above the Y-Y axis of the discharge slug 4 are significant, furthermore the fact that the discharge slug 4 is at least viacchodný. In addition, the discharge slug 4 formed in the region of the filling region 7 has a greater pitch than in the other regions, the pitch being greater than 1 D, preferably having a value of 1.1-2.5 D, the letter D indicating the diameter of the slug.
Prostredníctvom tohto usporiadania sa dosiahne to, že je možné relatívne velký objem odovzdávať v oblasti naplňovacej oblasti 2 do výtlačného lisu 1 a na výtlačný slimák 4, bez toho, že by bolo potrebné obávať sa upchania v odovzdávacej oblasti 11, pričom teraz je možné stláčať a plastifikovať velký objem v priebehu dopravy prostredníctvom výtlačného slimáka 4 vo výtlačnom lise 1.With this arrangement, it is achieved that a relatively large volume can be transferred in the area of the filling area 2 to the extruder 1 and to the extruder 4, without having to worry about clogging in the transfer area 11, and now it is possible to compress and plasticize the large volume during transport by means of the extrusion screw 4 in the extrusion press 1.
