COCLEA MODULARE A TRE PRINCIPI IN MATERIALE MODULAR AUGER WITH THREE PRINCIPLES IN MATERIAL
PLASTICO PER SOLLEVAMENTO DI FLUIDI PLASTIC FOR LIFTING FLUIDS
INTRODUZIONE INTRODUCTION
La Coclea modulare in materiale plastico per il sollevamento di fluidi può essere vantaggiosamente impiegata negli impianti di trattamento di reflui per il sollevamento di questi ultimi dai bacini di carico. The modular screw conveyor in plastic material for lifting fluids can be advantageously used in wastewater treatment plants for lifting the latter from the loading basins.
STATO DELLA TECNICA STATE OF THE TECHNIQUE
Attualmente le coclee in esercizio sono costituite da viti di Archimede realizzate in materiali metallici (soprattutto acciaio) e presentano masse e quindi inerzie estremamente elevate. La canna esterna alla vite per il contenimento dei fluidi in fase di sollevamento è normalmente realizzata in calcestruzzo armato e. gettato in opera. Le viti oggi in uso consentono il sollevamento dei fluidi per altezze dell’ordine di alcuni metri al massimo. Currently, the augers in operation are made up of Archimedes screws made of metal materials (especially steel) and have extremely high masses and therefore inertias. The barrel external to the screw for containing the fluids during the lifting phase is normally made of reinforced concrete and. cast in place. The screws in use today allow the lifting of fluids to heights of the order of a few meters maximum.
INCONVENIENTI DELLE ATTUALI TECNOLOGIE DISADVANTAGES OF CURRENT TECHNOLOGIES
Le masse ed i momenti d’inerzia dei sistemi oggi in uso richiedono l’impiego di motorizzazioni di elevata potenza e quindi consumo. L’elevato momento d’inerzia causa gravosi fenomeni torcenti e la possibilità di appoggio soltanto a monte ed a valle causa indesiderati fenomeni di accentuata flessione con stress importanti degli elementi strutturali e degli appoggi stessi. La costruzione metallica, trovandosi la coclea ad operare in ambiente aggressivo, favorisce fenomeni di deterioramento delle parli più esposte. Per elevazioni importanti è necessario predisporre più coclee in sequenza e, date le dimensioni, è necessario costruire appositi fabbricati multilivello, molto grandi e di onerosa realizzazione. Le dimensioni delle coclee attuali (monoblocco) necessitano di costosi trasporti eccezionali per la loro consegna nei siti di impiego. The masses and moments of inertia of the systems in use today require the use of high power and therefore consumption motors. The high moment of inertia causes severe twisting phenomena and the possibility of support only upstream and downstream causes undesirable phenomena of accentuated bending with significant stress on the structural elements and the supports themselves. The metal construction, since the auger operates in an aggressive environment, favors deterioration phenomena of the most exposed parts. For important elevations it is necessary to prepare several augers in sequence and, given the size, it is necessary to build special multilevel buildings, very large and expensive to build. The dimensions of the current augers (monobloc) require expensive exceptional transport for their delivery to the sites of use.
VANTAGGI DELLA COCLEA MODULARE IN MATERIALE PLASTICO ADVANTAGES OF THE MODULAR AUGER IN PLASTIC MATERIAL
Il nuovo sistema permette una riduzione consistente dei costi di costruzione poiché la coclea può essere realizzata anche con materiali plastici caratterizzati da scarse proprietà meccaniche; inoltre avendo la possibilità di poggiare, su rulli per il suo intero sviluppo in lunghezza in quanto la canna esterna può essere solidale con la vite, non ha necessità di avere un elevato momento di inerzia e non necessita di un sistema di appoggio immerso nel bacino di carico. La coclea può avere uno sviluppo lineare elevato proprio grazie alla presenza di rulli di appoggio disposti con continuità che ne evitano l’inflessione, consentendo di evitare disconnessioni lungo il percorso. La coclea può essere realizzata per conci assemblagli direttamente in opera. In tal modo possono essere ridotti i costi di trasporto (non v’è la necessità di trasporli eccezionali) e quelli di manutenzione ed eventuale sostituzione dei conci. La coclea, realizzando un perfetto accoppiamento tra vite e cilindro esterno, consente di aumentare l’efficienza di trasferimento del fluido. Sempre grazie ai rulli di appoggio continui la coclea può essere posta in rotazione da motori elettrici distribuiti lungo lo sviluppo di dimensioni e potenza richiesta inferiori, generando anche modesti sforzi torsionali. Essendo completamente chiusa la coclea non dà luogo ad emissioni di aerosol e per lo stesso motivo essa consente una drastica riduzione degli impatti da rumore. The new system allows a substantial reduction in construction costs since the screw can also be made with plastic materials characterized by poor mechanical properties; furthermore, having the possibility of resting on rollers for its entire length development as the external barrel can be integral with the screw, it does not need to have a high moment of inertia and does not require a support system immersed in the basin of load. The auger can have a high linear development thanks to the presence of continuously arranged support rollers that prevent it from inflection, allowing you to avoid disconnections along the way. The auger can be made for segments assembled directly on site. In this way, transport costs can be reduced (there is no need for exceptional transport) and maintenance costs and possible replacement of the segments. The auger, creating a perfect coupling between screw and external cylinder, allows to increase the fluid transfer efficiency. Also thanks to the continuous support rollers, the auger can be rotated by electric motors distributed along the length of a smaller size and power requirement, generating even modest torsional stresses. Being completely closed, the screw does not give rise to aerosol emissions and for the same reason it allows a drastic reduction of noise impacts.
DESCRIZIONE E PRINCIPIO DI FUNZIONAMENTO DESCRIPTION AND WORKING PRINCIPLE
Il principio di funzionamento della coclea modulare in materiale plastico è, in sostanza, il medesimo delle normali coclee in acciaio/calcestruzzo oggi in uso. La coclea viene posta in rotazione lungo il proprio asse (A) per mezzo d motorizzazioni elettriche o di altro tipo che possono essere singole oppure multiple in funzione delle dimensioni della coclea stessa, motorizzazioni che possono essere posizionate lungo lo sviluppo della coclea. La coclea dispone di una vite di Archimede interna a tre principi (tì), quindi con tre canalizzazioni per il sollevamento dei fluidi che è contenuta in un cilindro esterno a tenuta stagna in quanto solidale con la vite '(C) ed è supportata da sostegni a rulli folli (D) che possono essere puntuali o uniformemente distribuiti lungo l'intero sviluppo del'apparccchiatura. La coclea può essere realizzata in singolo pezzo in caso di modeste quote di sollevamento o in forma modulare mediante conci o moduli impiiabili assialmente fino a raggiungimento dell’altezza di sollevamento richiesta. The operating principle of the modular screw in plastic material is essentially the same as the normal steel / concrete screws in use today. The screw is rotated along its own axis (A) by means of electric or other types of motors which can be single or multiple depending on the size of the screw itself, which can be positioned along the length of the screw. The auger has an internal Archimedes screw with three principles (tì), therefore with three channels for lifting the fluids which is contained in an external watertight cylinder as it is integral with the screw '(C) and is supported by supports with idle rollers (D) which can be punctual or uniformly distributed along the entire development of the equipment. The auger can be made in a single piece in case of modest lifting heights or in modular form by means of segments or modules that can be installed axially until the required lifting height is reached.
CONCLUSIONI CONCLUSIONS
Dal punto di vista funzionale, una coclea siffatta consente di ottenere rendimenti idraulici pari o superiori a quelli delle attuali installazioni. Si deve inoltre ritenere che la maggiore affidabilità di funzionamento ed i minor impegni di potenza messi in gioco rendano questi dispositivi caratterizzati da un minore consumo energetico complessivo. From the functional point of view, such an auger allows to obtain hydraulic yields equal to or higher than those of current installations. It must also be considered that the greater operational reliability and the lower power commitments put into play make these devices characterized by a lower overall energy consumption.
Il trovato potrà essere modificalo mantenendo il concetto inventivo che ne è alla base, potendosi sostituire ogni dettaglio con altro tecnicamente equivalente. The invention can be modified while maintaining the inventive concept underlying it, since every detail can be replaced with another technically equivalent one.
