?SISTEMA DI FRANTUMAZIONE DI RIFIUTI PLASTICI CON SERIE DI LAME ROTANTI DEDICATE? ?CRUSHING SYSTEM FOR PLASTIC WASTE WITH SERIES OF DEDICATED ROTATING BLADES?
Descrizione Description
Campo della tecnica field of technique
La presente invenzione opera nell?ambito delle attrezzature di frantumazione e riciclaggio della plastica, in particolare si riferisce ad un frantumatore industriale. Pi? specificamente, l?oggetto del presente brevetto riguarda un sistema di frantumazione di materie plastiche dotato di una particolare sequenza di tipi di lame studiate per velocizzare il lavoro e allungare la vita delle stesse. The present invention operates in the field of plastic crushing and recycling equipment, in particular it refers to an industrial crusher. Pi? specifically, the object of the present patent concerns a system for crushing plastic materials equipped with a particular sequence of types of blades designed to speed up work and lengthen their life.
Arte nota Known art
La consapevolezza della societ? nei confronti della protezione ambientale ? in continuo aumento e il riciclaggio della plastica ? diventato sempre pi? diffuso. Il processo principale ? quello di frantumare i blocchi di plastica producendo materiali granulari, che vengono nuovamente utilizzati nelle apparecchiature di produzione. I trituratori industriali, utilizzati all?interno di sistemi e impianti di riciclaggio, dispongono di sistemi meccanici attraverso i quali ? garantito l?approvvigionamento dei materiali e la lavorazione dei rifiuti. Society awareness? towards environmental protection? ever-increasing and recycling of plastic ? has become more and more widespread. The main process? that of crushing plastic blocks into granular materials, which are again used in production equipment. Industrial shredders, used within recycling systems and plants, have mechanical systems through which guaranteed the supply of materials and the processing of waste.
I rifiuti che giungono ai diversi impianti di triturazione sono sottoposti a selezione prima di essere triturati. Lo scopo ? quello di ottenere lotti omogenei e compatibili tra loro, evitare di immettere nell?impianto di triturazione contenitori con residui liquidi, bombolette che abbiano contenuto gas e sostanze che per loro natura potrebbero favorire la formazione di incendi che danneggerebbero l?impianto e genererebbero danni all?area circostante. The waste that arrives at the various shredding plants is subjected to selection before being shredded. The purpose ? that of obtaining homogeneous and compatible batches, avoid introducing containers with liquid residues, cans that have contained gases and substances which by their nature could favor the formation of fires that would damage the plant and cause damage to the shredding plant? surrounding area.
Gli alberi contenenti le lame sono gli elementi fondamentali della struttura dei trituratori industriali per la frantumazione dei diversi materiali. Tuttavia, indipendentemente dal numero di alberi, ogni trituratore ? composto da parti fondamentali che accompagnano i rifiuti dalla prima fase del processo di triturazione fino alla conclusione. The shafts containing the blades are the fundamental elements of the structure of industrial shredders for crushing the various materials. However, regardless of the number of trees, each shredder is ? composed of fundamental parts that accompany the waste from the first phase of the shredding process to its conclusion.
L?invio del materiale destinato alla sminuzzatura avviene per caduta o per mezzo di un nastro trasportatore. In generale, la massa composta dai rifiuti che devono essere triturati ? caricata per mezzo di una gru a braccio idraulico. L?espulsione del prodotto triturato avviene per caduta, sotto al quale ? situato un nastro trasportatore che fa avanzare il prodotto fino al deposito o ai mezzi destinati al trasporto, come ad esempio autocarri. The material intended for shredding is sent by gravity or by means of a conveyor belt. In general, the mass composed of waste that must be shredded? loaded by means of a hydraulic crane. The expulsion of the shredded product takes place by falling, under which ? located a conveyor belt that advances the product to the warehouse or to means of transport, such as trucks.
La parte centrale del trituratore ? invece solitamente composta dagli alberi con annesse lame, in particolare, si possono avere uno, due, tre o quattro alberi. I trituratori monoalbero sono solitamente composti da: un cassetto spintore ad azionamento idraulico che spinge il materiale verso un rullo porta utensili che, grazie alla sua rotazione ed all?azione di una contro lama, effettua la pre-rottura e la macinazione del materiale. Il prodotto ? vagliato da una griglia forata che determina la dimensione finale del macinato. The central part of the shredder ? instead usually composed of trees with attached blades, in particular, you can have one, two, three or four trees. Single shaft shredders are usually composed of: a hydraulically operated pusher drawer which pushes the material towards a tool holder roller which, thanks to its rotation and the action of a counter blade, carries out the pre-breaking and grinding of the material. The product ? sieved by a perforated grid which determines the final size of the ground.
I trituratori bialbero, invece, sono composti da due alberi a lame rotanti. Una volta introdotto il materiale nella tramoggia e avviato l?impianto, il trituratore provvede alla presa e al taglio grossolano dello scarto. Il sistema di funzionamento del trituratore bialbero ? composto da: una tramoggia di carico e due alberi con elementi taglienti costituiti da frese a disco provvisti di uncini. Ciascun uncino ha la funzione di agganciare il prodotto e di trascinarlo fino alla fase del taglio, resa possibile grazie all?azione dei due alberi controrotanti. I pettini distanziatori mantengono puliti gli utensili facilitando lo scarico del materiale. The double-shaft shredders, on the other hand, are composed of two shafts with rotating blades. Once the material has been introduced into the hopper and the system has been started, the shredder takes care of picking up and coarsely cutting the waste. The operating system of the double shaft shredder? composed of: a loading hopper and two shafts with cutting elements consisting of disc cutters equipped with hooks. Each hook has the function of hooking the product and dragging it to the cutting stage, made possible thanks to the action of the two counter-rotating shafts. The spacer combs keep the tools clean by facilitating the unloading of the material.
Allo stato attuale, i dispositivi di frantumazione della plastica vengono generalmente inseriti nella scatola di frantumazione e mediante il supporto di uno spintore i rifiuti vengono spinti all?interno per essere triturati in pezzi pi? piccoli da lame rotanti. Dopo un uso prolungato, la lama, il portautensile e l'albero motore possono essere facilmente danneggiati a causa della fatica e usura generata nel tempo. Aumentare la durata della vita o dei cicli di manutenzione di questi elementi ? piuttosto difficile, specialmente per le lame, che data la natura del loro impiego hanno bisogno di continua manutenzione. At present, plastic shredder devices are generally inserted into the shredder box and by the support of a pusher the waste is pushed inside to be shredded into smaller pieces. small by rotating blades. After prolonged use, the blade, tool holder and motor shaft are easily damaged due to fatigue and wear generated over time. Increase the lifespan or maintenance cycles of these elements? rather difficult, especially for the blades, which due to the nature of their use need continuous maintenance.
Tuttavia ? possibile disegnare e modellare specifiche lame dedicate al tipo di materiale da triturare per il riciclo allungando di molto i cicli di manutenzione e la vita stessa delle lame. However ? It is possible to design and model specific blades dedicated to the type of material to be shredded for recycling, greatly extending the maintenance cycles and the very life of the blades.
Scopo del presente brevetto ? quindi quello di risolvere le suddette problematiche fornendo un netto miglioramento ai molteplici cicli di manutenzione richiesti, di conseguenza riducendo i costi di gestione e velocizzando il lavoro svolto. Purpose of this patent? therefore that of solving the aforementioned problems by providing a clear improvement to the multiple maintenance cycles required, consequently reducing management costs and speeding up the work carried out.
