Description

Tamburo essiccatore-mescolatore per il riciclo del 100% di materiale fresato stradale RAP (Reclaimed Asphalt Pavement). Dryer-mixer drum for the recycling of 100% of RAP (Reclaimed Asphalt Pavement) road milled material.

OGGETTO E CAMPO DI APPLICAZIONE DELL’INVENZIONE OBJECT AND FIELD OF APPLICATION OF THE INVENTION

Nella produzione dei conglomerati bituminosi viene sempre In the production of bituminous conglomerates it always comes

riveniente dalla fresatura del manto stradale (comunemente chiamato fresato, riciclato o RAP) contenente quindi aggregati lapidei e filler già impastati con il bitume e/o altri unificanti o modificanti. coming from the milling of the road surface (commonly called milled, recycled or RAP) therefore containing stone aggregates and fillers already mixed with bitumen and / or other unifying or modifying agents.

Diverse sono le tecnologie tuttora in uso che però non permettono una perfetta amalgama e presentano punti deboli rispetto all'emissione delle polveri, del vapore e fumo prodotto dal bitume (blue smog) ed anche l'utilizzo del filtro a maniche di tessuto che, secondo la tipologia del prodotto immesso, può risultare a volte insufficiente. There are several technologies still in use which, however, do not allow perfect amalgamation and have weak points with respect to the emission of dust, steam and smoke produced by the bitumen (blue smog) and also the use of the fabric bag filter which, according to the type of product introduced may sometimes be insufficient.

VANTAGGI RICONDUCIBILI ALL’APPLICAZIONE DELL'INVENZIONE ADVANTAGES RELATED TO THE APPLICATION OF THE INVENTION

Questa nuova tecnologia che stravolge ogni concetto attualmente in uso e che difficilmente è comparabile con altre soluzioni già brevettate in quanto non ancora esistenti a livello mondiale, permette prima di tutto il riciclo del 100% del materiale fresato stradale con un'amalgama ottimale del prodotto finito, eliminando totalmente la fuoriuscita di polveri, non emettendo fumi di combustione inquinanti, e consentendo un totale abbattimento dei vapori di bitume e/o altri amalgamanti, unificanti o modificanti siano essi a composto chimico che naturale, poiché vengono captati e distrutti da apposito camera di turbolenza. This new technology that distorts every concept currently in use and which is hardly comparable with other already patented solutions as they do not yet exist worldwide, first of all allows the recycling of 100% of the road milled material with an optimal amalgam of the finished product. , totally eliminating the escape of dust, not emitting polluting combustion fumes, and allowing a total abatement of bitumen vapors and / or other amalgamants, unifying or modifying whether they are chemical or natural, since they are captured and destroyed by a special chamber turbulence.

DESCRIZIONE TECNICA DELL'INVENZIONE TECHNICAL DESCRIPTION OF THE INVENTION

Per abbreviazione si riporta il principio, sistema e processo di detto nuovo macchinario la cui costruzione ed applicazione può avvenire in diversi modi e difendibile secondo il concetto espresso nei termini che seguono. By abbreviation we report the principle, system and process of this new machinery whose construction and application can take place in different ways and can be defended according to the concept expressed in the following terms.

Il macchinario che fa parte del settore metalmeccanico e quindi con materiali di base in lamiere e profilati in ferro ed acciaio, è composto da tre tamburi (chiamati anche cilindri) concentrici interagenti sia direttamente che per induzione, come meglio spiegato sotto, solidali fra di loro e rotanti nell'insieme su quattro ruote di guida (5) che supportano due anelli di rotazione (4) applicati sul tamburo esterno indicato con il n. 3. Le ruote guida sono situate su telaio rigido (6) due per parte, con motorizzazioni elettriche individuali. Il sistema della rotazione può avvenire anche nel modo tradizionale sia esso a due motorizzazioni, sia con corona dentata, collocata sempre nel tamburo esterno ed azionata da pignone motorizzato elettricamente o con motore a combustione interna, pur sempre su quattro ruote guida che supportano gli anelli di rotazione. The machinery that is part of the metalworking sector and therefore with basic materials in sheet metal and iron and steel profiles, is composed of three concentric drums (also called cylinders) interacting both directly and by induction, as better explained below, integral with each other and rotating as a whole on four guide wheels (5) which support two rotation rings (4) applied on the external drum indicated with the no. 3. The guide wheels are located on a rigid frame (6) two on each side, with individual electric motors. The rotation system can also take place in the traditional way, whether with two motors or with a toothed crown, always located in the external drum and operated by an electrically motorized pinion or with an internal combustion engine, albeit always on four guide wheels that support the rings. rotation.

Il tamburo indicato con il n. 1 rappresenta la camera di combustione che, unitamente al tamburo indicato con il n. 2 (camera di essiccazione e mescolazione), nonché con il tamburo indicato con il n. 3 (camera esterna di riscaldamento e convogliamento fumi) al quale sono applicati gli anelli di rotazione (4) sono legati in un tutt’uno aventi due punti comuni individuabili nel frontone della parte anteriore (7) e nel frontone della parte posteriore (8). La camera esterna (3) è dotata di un isolamento termico formato da lana di roccia ad alta densità e copertura in lamierino di acciaio sì da permettere un contenimento importante di calore. The drum indicated with no. 1 represents the combustion chamber which, together with the drum indicated with no. 2 (drying and mixing chamber), as well as with the drum indicated with no. 3 (external heating and fumes conveyance chamber) to which the rotation rings (4) are applied are linked as a whole having two common points identifiable in the pediment of the front part (7) and in the pediment of the rear part (8) . The external chamber (3) is equipped with a thermal insulation formed by high-density rock wool and a steel sheet cover so as to allow an important containment of heat.

Il frontone della parte anteriore presenta l'alloggiamento (9) nel quale viene applicato il bruciatore (10) che immette la fiamma nel tamburo n. 1. Detto frontone comprende pure la bocca (11) per l’introduzione del materiale fresato (RAP) che viene immesso nel tamburo n. 2, tramite nastro alimentatore, senza mai venire a contatto diretto sia con il tamburo n. 1 che con il tamburo n. 3. Il materiale fresato e bituminoso, al quale eventualmente possono essere aggiunti aggregati vergini, marcia all’interno del tamburo (2) in equicorrente con la fiamma del bruciatore (10). Uno speciale sistema di palettature all'interno della camera (2) fa girare il materiale sul fondo spingendolo in avanti rimescolandolo, senza che lo stesso venga mai a contatto con l’involucro ad alta temperatura della camera di combustione (1). The pediment of the front part has the housing (9) in which the burner (10) is applied, which introduces the flame into the drum n. 1. Said pediment also includes the mouth (11) for the introduction of the milled material (RAP) which is fed into the drum n. 2, by means of a feeder belt, without ever coming into direct contact with either the drum n. 1 and with the drum n. 3. The milled and bituminous material, to which virgin aggregates can possibly be added, runs inside the drum (2) in equicurrent with the burner flame (10). A special system of blading inside the chamber (2) turns the material on the bottom pushing it forward, stirring it, without ever coming into contact with the high temperature casing of the combustion chamber (1).

Invertendo il sistema di introduzione è possibile far viaggiare il materiale da essiccare e mescolare anche in controcorrente con la fiamma del bruciatore. In ogni caso il riscaldamento ad induzione è pur sempre a doppio passaggio di fumi caldi. By inverting the introduction system it is possible to make the material to be dried travel and mix also in countercurrent with the burner flame. In any case, induction heating is still a double passage of hot fumes.

Il materiale che si deumidifica e riscalda, per doppia induzione di calore, all’interno della camera di essiccazione e mescolazione (2) non venendo mai a contatto con l’involucro (1) non clincherizza e tantomeno brucia o cuoce, mantenendo un prodotto di alta qualità ed elastico. The material that dehumidifies and heats, by double induction of heat, inside the drying and mixing chamber (2) never coming into contact with the casing (1) does not clincher and even less burns or cooks, maintaining a product of high quality and elastic.

Il calore prodotto all'interno del tamburo (1) dalla fiamma del bruciatore (10) viene convogliato, all’altezza del frontone della parte posteriore (8), nel terzo cilindro (3), in controcorrente alla fiamma, inducendo un riscaldamento ulteriore senza contatti diretti con il materiale (RAP) già introdotto e marciante nel cilindro n. (2) e convogliando i soli gas esausti e puliti della combustione, verso l'uscita (12) collocata nel frontone anteriore (7) terminante con un camino libero verticale (13). Per questi fumi non è necessario alcun trattamento in quanto non contengono polveri di alcun genere ed il processo di combustione è tale e quale a quello di una semplice caldaia o di qualsiasi altra apparecchiatura che niente deve trattare all’interno della camera di combustione. The heat produced inside the drum (1) by the flame of the burner (10) is conveyed, at the height of the pediment of the rear part (8), into the third cylinder (3), in counter-current to the flame, inducing further heating without direct contact with the material (RAP) already introduced and running in cylinder n. (2) and conveying only the exhausted and clean combustion gases, towards the outlet (12) located in the front pediment (7) ending with a free vertical chimney (13). No treatment is required for these fumes as they do not contain dust of any kind and the combustion process is the same as that of a simple boiler or any other equipment that nothing must treat inside the combustion chamber.

L’uscita dei fumi dal camino non necessita di alcun aspiratore in quanto avviene dall'inerzia di spinta dell'aria introdotta nella camera di combustione dal ventilatore del bruciatore. The exit of the fumes from the chimney does not require any aspirator as it occurs from the inertia of the thrust of the air introduced into the combustion chamber by the burner fan.

Le temperature dei fumi nel terzo cilindro (3) sono controllate automaticamente e rapportate al calore del secondo cilindro (2) ed al prodotto essiccato e mescolato al fine di regolare le temperature del prodotto finito, agendo sulle potenzialità del bruciatore. The temperatures of the fumes in the third cylinder (3) are automatically controlled and related to the heat of the second cylinder (2) and to the dried and mixed product in order to regulate the temperatures of the finished product, acting on the potential of the burner.

In tal modo possono essere regolate le quantità di prodotto fresato immesso (+/-) sulla base della temperatura in uscita dello stesso (-/+). In this way, the quantities of milled product introduced (+/-) can be adjusted on the basis of its outlet temperature (- / +).

I fumi prodotti dal riscaldamento del materiale fresato contenente bitume vengono convogliati, allo scarico del prodotto finale (15), in un camino con camera di turbolenza (20) collocato nel frontone posteriore (8) si da venire completamente distrutti da un uno o più bruciatori (16 - 17). The fumes produced by the heating of the milled material containing bitumen are conveyed, to the discharge of the final product (15), in a chimney with a turbulence chamber (20) located in the rear pediment (8) to be completely destroyed by one or more burners (16-17).

Lo scarico del prodotto finale avviene, come detto in precedenza nel frontone posteriore ed è composto da quattro o più scivoli (14) aperti nella parte terminale che partono dal tamburo n. 2 ed attraversano il tamburo n. 3 senza che il prodotto venga a contatto con i fumi, ed immettono il prodotto finito nella tramoggia tampone di scarico (18) che, avendo un fondo apribile, rimane chiusa finché non è stimolata dal comando di apertura sia per il carico in benna o direttamente su camion (nella soluzione sopraelevata). The unloading of the final product takes place, as previously mentioned in the rear pediment and is composed of four or more chutes (14) open in the terminal part that start from the drum n. 2 and pass through the drum n. 3 without the product coming into contact with the fumes, and introduce the finished product into the discharge buffer hopper (18) which, having an opening bottom, remains closed until it is stimulated by the opening command either for loading into the bucket or directly on trucks (in the overhead solution).

Dal frontone anteriore viene introdotta nel tamburo (2) una barra di spruzzatura del bitume (19) necessaria qualora debba essere immessa un’aggiunta, al prodotto fresato, di legante od altro additivo liquido, sia essa a peso o con sistema volumetrico. From the front pediment, a bitumen spraying bar (19) is introduced into the drum (2), necessary if an addition, to the milled product, of binder or other liquid additive, whether by weight or with a volumetric system, is to be introduced.

La camera di turbolenza (20) per l’abbattimento dei fumi è dimensionata sulla base dei rapporti fra consumo del bruciatore, temperatura e portata dei vapori, tipologia dei bitumi lavorati, tipo di alimentazione, si da abbattere CO, HC, NOx ed altri eventuali inquinanti bituminosi, ai minimi livelli delle più restrittive norme antinquinamento. I vantaggi di detto sistema con camera di turbolenza sono riassumibili nell’elevata efficienza di combustione (oltre il 99%). The turbulence chamber (20) for the abatement of fumes is sized on the basis of the relationship between burner consumption, temperature and flow rate of the vapors, type of bitumen processed, type of power supply, CO, HC, NOx and other possible bituminous pollutants, at the minimum levels of the most restrictive anti-pollution regulations. The advantages of this system with a turbulence chamber can be summarized in the high combustion efficiency (over 99%).
