Spôsob a zariadenie na likvidáciu starých pneumatík deštrukciou.Method and apparatus for destruction of old tires.

Vynález sa týka spôsobu a zariadenia na likvidáciu starých pneumatík deštrukciou.The invention relates to a method and apparatus for destruction of old tires.

Likvidácia starých pneumatík je veľmi ťažko riešiteľný problém. Jednak spôsobuje veľké ťažkosti oddeliť od gumy kovové časti uložené v gume pred tým, ako táto prechádza rozomieľacími strojmi, jednak existujú možnosti opätovného zhodnotenia starej gumy len vtedy, keď je stará guma k dispozícii vo veľmi jemne rozčlenenom stave. prakticky ako prachová. pretože len v tomto stave môže byť stará gumu zase zhodnotená v gumárenskom priemysle ako p r í s a d a pre v ý r o t) u n o v é ho .g u m o v é h o t o v á r u.Disposal of old tires is a very difficult problem to solve. On the one hand, it makes it difficult to separate the metal parts stored in the rubber from the rubber before it passes through the grinding machines. On the other hand, there is a possibility of reusing old rubber only when the old rubber is available in a very finely divided state. practically as dusty. because only in this state can the old rubber be recycled in the rubber industry as a process and for the production of rubber.

E<oli podniknuté rôzne pokusy na uvoľnenie kovových častí pneumatík. Pretože v následných pracovných postupoch by kovové diely otupil i u ž za k r á t k y č a s o b r á b a c i e? n á s t. r o j e a vie d .1 i b yVarious attempts have been made to release metal parts of tires. Because in the subsequent workflows, the metal parts would even dull the edges? n á s t. r o j e a d .1 i b y

k. rýchlemu opotrebeniu. Preto boli vystavené pneumatiky, ako je znázornené v DE· 39 11 082 Al, induktívnemu poľu, ktorým sa vložky veľmi zohrievajú a tým vyži hajú. V medznej vrstve sa rozpadá spoluzohriata guma na uhľový prach, ovšem za značného vytvárania dymu a zápachu, takže sa tento spôsob môže robiť iba v špeciálnych komorách so špeciálnymi zariadeniami zabraňujúcimi výstupu dymu a zápachu. Týmto spôsobom je umožnené následné rozd rvovanie, aj keď v y ž í h a n é k o v o v é d i e 1 s·' o p o t r e b o v á v a j ú nástroje na opracovanie stále ešte viac ako gumové diely.k. rapid wear. Therefore, as shown in DE · 39 11 082 A1, the tires have been subjected to an inductive field by which the inserts become very hot and thus ignite. In the boundary layer, the co-heated rubber breaks down to carbon dust, but with considerable smoke and odor production, so that this process can only be done in special chambers with special smoke and odor exit devices. In this way, subsequent grinding is possible, even if the working tools are still more than the rubber parts.

Aby sa sta r é p n e u m a t i k y r o z d r v i .1 i , n a s a d z u j ú s a r e z a c i e a obrábacie nástroje» Podľa DE 29 11 251 02 sa pneumatika nasadí v upínacom zariadení na tri smerom von vysúvateľné čapy, Potom sa rotujúcimi nožmi urobí tangenciálny rez a odreže sa behúň s bočnými pruhmi, od Pätiek Priliehaiúcich na obruč . ktoré prednostne obsahuiú kovové vložky a následne sa rozreže ďalšími kotúčovými nožmi na pru.hy a odovzdá sa na zariadenie priečneho rezania. F'r e uskutočnenie tohto zmenšovania i e· nutné značné strojové výbaven i e. Z1s k a jú sa n are zan é kú sk y stare i gumy, k t o ré ako také sa nedajú znova použiť a musia byť podrobené ešte ďalším spôsobom opracovania.In order to age old tires .1 i, use cutting tools »According to DE 29 11 251 02, the tire is mounted in the clamping device on three outwardly extending studs, then a tangential cut is made with the rotating blades and the tread with side strips is cut, from Heels Adhering to the Hoop. which preferably comprise metal inserts and subsequently cut into other strips with further circular knives and passed to a cross-cutting device. To accomplish this reduction, considerable machine equipment is also required. There are old ages of rubber which cannot be reused as such and have to be subjected to further working methods.

Iné stroje, búrajúce staré pneumatiky takisto v radiálnom smere sú shreddery, ktoré zabera iú rotujúcimi nožovými valcami na obvode behúňa, rozdrvia pneumatiku na lupienky a v teito činnosti pokračujú radiálne (US 36 93 894 Al ). Podobným spôsobom pracuje stroj podľa SU 13 88 294 Al, pričom sa tu pneumatika upne a z lisu je obojstranne na bočné pruhy dosedajúcimi segmentmi, čím sa ohne a zdeformuje behúň a je privádzaný v tomto zúženom stave k nožom valca shredderu.Other machines demolishing old tires also in the radial direction are shredders that engage rotating knife rollers on the tread periphery, crush the psoriasis tire and continue this operation radially (US 36 93 894 A1). In a similar manner, the machine operates in accordance with SU 13 88 294 A1, where the tire is clamped here and is pressed from the press on both sides to the side strips by abutting segments, bending and deforming the tread and fed to the blades of the shredder cylinder.

Podobne prebieha rozrušovanie v stroji podľa DE 37 04 725Similarly, the erosion takes place in a machine according to DE 37 04 725

Vynález sa vy var ú. v a nedostatkov stavu techniky. Úlohou vynálezu je maximálne jednoduchými prostriedkami rozrušiť staré pneumatiky bez predchádzajúceho odstraňovania kovových dielov a bez opotrebovania nástrojov.The invention boils. and the shortcomings of the prior art. SUMMARY OF THE INVENTION It is an object of the invention to destroy old tires without the removal of metal parts and tool wear without the least possible means.

Podstatou vynálezu je. že sa stará pneumatika, ktorá má byť rozrušená upne medzi dva valce, z ktorých .jeden dosadá na pätky určené pre nasadenie na obruč, druhý na behúň pneumatiky, že sa valce stlačia . veľkou silou proti sebe, že'sa pritom pneumatika stlačí v medzere medzi valcami, zlisuje sa jej pôvodný tvar a zmenší sa hrúbka behúňa a že sa valce nechajú rotovať.The subject of the invention is. That is, the old tire to be broken is clamped between two rollers, one of which bears on the beads intended for mounting on the tire, the other on the tread of the tire, that the rollers are compressed. with great force against each other that the tire is compressed in the gap between the rollers, the original shape is compressed and the tread thickness is reduced and the rollers are allowed to rotate.

Týmto procesom stlačovania pri súčasnej rotácii sa rozmrví stará pneumatika na malé .jemné diely a dielky. Týmto spôsobom sa rozpadne. Ostanú prstencové kovové vložky, ktoré sa po procese rozpadu odoberú z valca.This compressing process, while rotating, breaks up the old tire into small fine parts and pieces. In this way it disintegrates. Annular metal inserts remain, which are removed from the cylinder after the disintegration process.

P r e tento spôsob sa môžu použiť val c: e s hladkým povrchom, povrch môže byť zdrsnený, môže byť účelné usporiadať na povrchu valca vyvýšeniny a/alebo prehĺbením', ktoré vedú pneumatiku počas rotácie k stredovej rovine valcov. Je prekvapivé vidieť, ako sa stará pneumatika pri svojej rotácii, rozpadá pod použitým tlakom bez toho, aby na ňu pôsobili nože, tvrdokovové doštičky, rašple alebo iné nástroje opracovania. Tento rozpad pneumatiky pod tlakom a za rotácie sa dá vysvetliť tým, že vložky pôsobia na gumu ako nože, keď sa táto snaží pod veľkým lisovacím tlakom v medzere medzi valcami uhnúť na všetky strany.In this method, a smooth surface roller can be used, the surface can be roughened, it may be expedient to arrange elevations and / or depressions on the surface of the roller which guide the tire to the central plane of the rollers during rotation. It is surprising to see how the tire, when rotating, breaks up under the applied pressure without being subjected to blades, carbide inserts, rasps or other machining tools. This breakdown of the tire under pressure and rotation can be explained by the fact that the inserts act as blades on the rubber when it tries to bend to all sides under high pressing pressure in the gap between the rollers.

Valce cylinders sa the mô ž u they can nechať leave rotovať rotate r o z d i e 1 n o u o b v o d o v o u r o z d i e n o u o b o o o o o rýchlosťou, speed, aby to sa the navyše? do Moreover? to spôsobu way v n i e so1 ešte e fe k t v n i e so1 still e fe k t roz tierania. roz rubbing. Spôsob process sa the ale d á but d á rea1izovať rea1izovať nielen z not only z a použitia iba dvoch and using only two

valcov, môže byť výhodné, keď sa použi je? pre? dosadnutie na Pätky valec o priemere, ktorý je podstatne? menší ako priemer pneumatiky, keď sa nechá mimo druhého valca dosadnúť na behúň pneumatiky pod veľkým lisovacím tlakom tretí va'lec, pričom tr.i.Cylinders can be advantageous when used is? for? seating on the Feet cylinder with a diameter that is substantially? smaller than the diameter of the tire when the third roll is allowed to rest on the tire tread outside the second roller under high pressing pressure, with the tr.i.

: osi týchto valcov zvierajú tupý uhol, alebo ležia v jednej i rovine, at keď sa v dôsledku toho pneumatike vnúti nekruhový, j prednostne hruškovitý tvar. Tým sa nevyvíja na pneumatiku iba ,í dvakrát proces stlačovania. ale pneumatika je tlačená do tvaru ilThe axes of these rollers form an obtuse angle or lie in the same plane, and when, as a result, the tire has a non-circular, preferably pear-shaped, shape inside. This not only develops the compression process on the tire twice. but the tire is pushed into the shape of il

J i · ktorý nie je kruhový, pričom medzi týmito troma valcami sa ? polomer pneumatiky podstatne zmenší, guma je oveľa viac namáhaná ú Ý j · trhaním a týmto spôsobom odpraskajú oveľa skôr kúsky gumy.J i · which is not circular, taking between these three cylinders with? the radius of the tire is significantly reduced, the rubber is much more stressed by tearing and in this way the pieces of rubber are more likely to burst.

Nielenže je možné vnútiť pneumatike nekruhový, hruškovitý alebo ‘3 kvapkovitý tvar, ale môže sa aj vnútiť iným spôsobom do :<j srdcovitého tvaru, keď sa mimo valec dosadajúci na Pätky jí pneumatiky usporiada navyše ešte druhý, takisto na Pätky « dosadajúci valec a keď sa valec dosadajúci na behúň zatlačí do ;1 med z i priestoru medzi oba na pätky pneumatiky dosadajúce valce., .; Týmto spôsobom sa vnúti pneumatike jej úplne cudzí tvar a tým sa ešte ďalej vystupňuje opotrebenie vedúce k romrveniu.Not only is it possible to impart a non-circular, pear-shaped or 3-drop shape to the tire, but it can also be implanted in another way into: a heart-shaped shape when the tire is arranged in addition to the bead on the beads; the roller abutting the tread is pushed into the space between the two abutment rollers of the tire.,. In this way, the tire is completely alien to the inside of the tire, and the wear leading to crushing is further exacerbated.

Drsné povrchy valcov zvyšujú trenie·, použitie hrubo zubatého povrchu valca vyvoláva procesy trhania vo vložkách a zvýšené namáhanie v ohybe s následným roztrhaním dielov g um v.Rough roller surfaces increase friction, the use of a coarse-toothed roller surface induces tearing processes in the liners and increased bending stress with subsequent tearing of the g µm v parts.

Pre vykonanie hore uvedených spôsobov sa používajú lisy·, ktoré pritláčajú valce na. seba p o d veľkým tlakom. Tento spôsob sa ale dá uskutočniť bez takýchto lisov, ak sa použijú tri valce s osami usporiadanými v jednej rovine, z ktorých stredný má menší priemer'ako je priemer pätiek pneumatiky, ktorá sa má zničiť, a z ktorých oba vonkajšie majú vybrania v tvare segmentu kruhového kotúča s priemerom väčším ako je priemer pneumatiky, ktorá sa má zničiť a mimo vybranie, ale s týmto susediace, ma jú úsek, obvodu so zväčšujúcim sa polomerom. Pritom je účelné, keď sa uloží vonkajší valec posuvne proti tlaku tanierových pružín.In order to carry out the above methods, presses are used to press the rollers against. pressure. However, this method can be carried out without such presses if three cylinders with axes arranged in one plane are used, the middle of which has a smaller diameter, such as the bead diameter of the tire to be destroyed, and both of which have recesses in the shape of a segment of a circular a roll with a diameter greater than the diameter of the tire to be destroyed and adjacent to the recess, but adjacent to it, has a section of circumference with increasing radius. In this case, it is expedient for the outer cylinder to be displaceable against the pressure of the disc springs.

Zariadenie na likvidáciu starých pneumatík deštrukciou podľa vynálezu pozostáva z dvoch valcov, z ktorých minimálne jeden má menší priemer ako je priemer pätiek pneumatiky určenej k likvidácii a je určený pre dosadnutie na pätky, druhý je určený pre dosadnutie na behúň pneumatiky určenej k likvidácii, z. pohonu pre minimálne jeden valec a z posuvného lisovacieho zariadenia, ktorým sa dá pritlačiť ..jeden valec na druhý za silného stlačenia pneumati ky.The device for destroying old tires by destruction according to the invention consists of two rollers, at least one of which has a smaller diameter than the diameter of the bead of the tire to be disposed and is intended to abut the bead, the other is intended to abut the tread of the tire to be disposed of. actuator for at least one roller and from a sliding press device by which one roller can be pressed against the other by pressing the tire firmly.

Toto zariadenie sa dá vyrobiť jednoduchými prostriedkami a vyznačuje sa tým, že pracuje prakticky bez opotrebenia..This device can be manufactured by simple means and is characterized by its virtually wear-free operation.

Ak sa chce dať pneumatike pri jej deštrukcii hruškovitý tvar, aby sa deštrukcia ešte zrýchlila, ..je účelné, keď sa predpokladá tretí, na behúň pneumatiky pritlačí, teľný valec, pričom osi valcov spolu zvierajú tupý uhol a stredný valec má podstatne menší priemer ako pneumatika určená k ividác. i i ,If it is desired to give the tire a pear shape when the tire is destroyed, in order to accelerate the destruction, it is expedient, when the third one is expected to press against the tread of the tire, with the caliper, Tire designed for dividers. i i,

Ak sa chce naproti tomu ' dať pneumatike pri deštrukcii srdcovitý tvar, je účelné, keď je predpokladaný tretí valec, ktorého priemer je podstatne menší ako ..je priemer pätiek pneuma t. i k y u rč.en e „jIf, on the other hand, it is desired to give the tire a heart-shaped shape during destruction, it is expedient if a third cylinder whose diameter is substantially smaller than the diameter of the beads of the tire is provided. i k y u rc.en e „j

The tire intended for the tire. the roller resting on the tread is pushed into the intermediate space between the two feet resting on the roller.

Pri týchto vyhotoveniach je nutné použitie lisu,aby sa valce dali proti sebe tlačiť veľkou silou, aby sa pneumatika stlačila medzi valcami.In these embodiments, it is necessary to use a press so that the rollers can be pressed against each other with great force to compress the tire between the rollers.

Použitie takého lisu nie ie nutné, ak sú usporiadané'tri valce s približne v jednej rovine ležiacimi osami valcov, z ktorých má stredný m en ô í priemer ako je priemer pätiek pneumatiky určenej k likvidácii a z ktorých oba vonkajšie majú vždy jedno vybranie v tvare segmentu kruhového kotúča s priemerom väčším ako je priemer pneumatiky, ktorá má byť zničená a vvkazu iú mimo vybranie, ale s ním susediaci úsek obvodu so zväčšujúcim sa polomerom.The use of such a press is not necessary if there are three cylinders with approximately one plane of the axes of the cylinders, of which the diameter is less than the diameter of the bead of the tire to be disposed of, and each of which has one segment-shaped recess. a circular disc with a diameter greater than the diameter of the tire to be destroyed and, in fact, outside the recess but adjacent to the circumferential section with increasing radius.

Aby sa do deštrukčných strojov starých pneumatík dalo zakladať a aby sa dali odstrániť oceľové prstencové vložky, ktoré zostali vo valcoch, je účelné, aby minimálne ten valec, na ktorý d o s a d a j ú p ä t k y p n e u m a t i k y u r- č e n e j k .1. i k v i d á c i i , b o J. u 1 o ž e n ý i i jIn order to load and remove steel annular liners remaining in the rollers, it is expedient that at least the roll on which the tires are held in the old tire destruction machines is .1. i k i d i i, b o J. u 1 o e n i i j
