DESCRIZIONE DESCRIPTION
dell’invenzione avente per titolo: of the invention entitled:
“ Procedimento di pulitura di elementi riscaldanti per acqua, in particolare resistenze corazzate “ "Process for cleaning water heating elements, in particular armored resistors"
La presente invenzione concerne un procedimento di pulitura di elementi riscaldanti per acqua, in particolare resistenze corazzate. The present invention relates to a cleaning process for water heating elements, in particular armored resistances.
Sono noti elementi riscaldanti per acqua costituiti sostanzialmente da una guaina in acciaio alloggiante internamente un filo resistivo separato dalla guaina da una sostanza dielettrica, in particolare ossido di magnesio. Heating elements for water are known substantially constituted by a steel sheath internally housing a resistive wire separated from the sheath by a dielectric substance, in particular magnesium oxide.
Allo scopo di rendere privo di ossidazioni e di irregolarità la superficie della guaina, che potrebbero consentire al detersivo ed al calcare di accumularsi con conseguenti fenomeni di corrosione, questa viene sottoposta ad un trattamento di finitura generalmente una lucidatura in bagno elettrolitico. In order to make the surface of the sheath free from oxidation and irregularities, which could allow the detergent and limescale to accumulate with consequent corrosion phenomena, this is subjected to a finishing treatment, generally a polishing in an electrolytic bath.
Al termine del bagno elettrolitico la resistenza viene lavata con acqua calda, eventualmente leggermente alcalina, allo scopo di neutralizzare i residui acidi del bagno. At the end of the electrolytic bath the resistance is washed with hot water, possibly slightly alkaline, in order to neutralize the acid residues of the bath.
Tale procedimento di pulitura presenta tuttavia alcuni inconvenienti: - un costo elevato dovuto sia alla presenza dell’impianto elettrolitico in sè sia alla necessità di prevedere un impianto di depurazione delle acque di lavaggio e di smaltimento dei bagni, However, this cleaning process has some drawbacks: - a high cost due both to the presence of the electrolytic system itself and to the need to provide a purification system for the washing water and disposal of the bathrooms,
- una bassa produttività, - low productivity,
- una laboriosità operativa di preparazione della resistenza alla fase di elettropulitura dovuta ad un pretrattamento di pulitura e sgrassamento di eventuali impronte che a seguito dell’elettropulitura verrebbero esaltate e riportate in modo indelebile sulla resistenza, - an operational laboriousness of preparation of the resistance to the electro-cleaning phase due to a pre-treatment of cleaning and degreasing of any fingerprints that, following the electro-cleaning, would be enhanced and indelibly marked on the resistance,
- una pulitura non totale in quanto la guaina richiede la protezione delle estremità che pertanto non vengono pulite. - non-total cleaning as the sheath requires the protection of the ends which therefore are not cleaned.
Scopo dell'invenzione è di eliminare tali inconvenienti e di realizzare un procedimento che consenta di effettuare la pulitura della resistenza in un modo completamente automatizzato, che presenti una elevata produttività e costi contenuti, che richieda una bassa manutenzione e che non presenti alcun problema ecologico. The object of the invention is to eliminate these drawbacks and to provide a process which allows cleaning of the resistance to be carried out in a completely automated way, which has a high productivity and low costs, which requires low maintenance and which does not present any ecological problem.
Secondo l'invenzione tutti questi scopi ed altri che risulteranno dalla descrizione che segue sono raggiunti con un procedimento di pulitura di elementi riscaldanti per acqua, in particolare resistenze corazzate caratterizzato dal fatto che si effettua una pulitura per abrasione meccanica. According to the invention, all these objects and others that will emerge from the following description are achieved with a cleaning process of heating elements for water, in particular armored resistances characterized in that cleaning is carried out by mechanical abrasion.
La presente invenzione viene qui di seguito ulteriormente chiarita con riferimento alla allegata tavola di disegni raffigurante in pianta schematica un impianto per effettuare il procedimento secondo l’invenzione. The present invention is further clarified below with reference to the attached table of drawings showing a schematic plan of a plant for carrying out the process according to the invention.
Come si vede dalle figure l'impianto per effettuare il procedimento secondo l’invenzione comprende sostanzialmente una tramoggia 2 di carico alloggiente le singole resistenze 4 già assemblate e cioè con il filo resistivo inserito nella guaina e separato da questa da materiale dielettrico ad esempio ossido di magnesio. As can be seen from the figures, the plant for carrying out the process according to the invention substantially comprises a loading hopper 2 housing the single resistors 4 already assembled, i.e. with the resistive wire inserted in the sheath and separated from this by dielectric material, for example oxide of magnesium.
Dalia tramoggia di carico fa capo un trasportatore 6 delle singole resistenze verso una prima situazione di pulitura 8 ed una seconda situazione di brillantatura 10. L’uscita del trasportatore è collegata ad una tramoggia di scarico 12. A conveyor 6 of the individual resistances leads from the loading hopper towards a first cleaning situation 8 and a second polishing situation 10. The conveyor outlet is connected to a discharge hopper 12.
In particolare le stazione di pulitura 8 e di brillantatura 10 comprendono due mandrini 14 di bloccaggio della resistenza e due spazzole 16 in fibra vegetale ad asse orizzontale a ciascuna delle quali è affacciata un pane 18 di pasta abrasiva. In particular, the cleaning 8 and polishing 10 stations comprise two mandrels 14 for locking the resistance and two brushes 16 in vegetable fiber with horizontal axis, each of which faces a bread 18 of abrasive paste.
Le spazzole sono montate su di un telaio traslabile 20. The brushes are mounted on a movable frame 20.
Il procedimento secondo l’invenzione prevede che la singola resistenza 4 venga scaricata dalla tramoggia 2 di carico sul trasportatore 6 per essere inviata alla stazione di pulitura 8 dove essa viene bloccata dai mandrini di bloccaggio 14. Allo stesso tempo le spazzole 16 vengono azionate in modo che, a seguito della loro rotazione, le fibre si impastino di pasta abrasiva e allo stesso tempo effettuino la pulitura meccanica della resistenza. In questa fase le spazzole vengono traslate lungo il loro asse in modo da effettuare la pulizia di tutta la resistenza. Successivamente la resistenza viene portata alla stazione di brillantatura dove vengono effettuate le stesse operazioni descritte in precedenza. Ai termine della fase di pulizia la resistenza viene inviata alla tramoggia di scarico 12. The method according to the invention foresees that the single resistance 4 is unloaded from the loading hopper 2 onto the conveyor 6 to be sent to the cleaning station 8 where it is blocked by the locking mandrels 14. At the same time the brushes 16 are operated in such a way. that, following their rotation, the fibers become mixed with abrasive paste and at the same time carry out the mechanical cleaning of the resistance. In this phase the brushes are moved along their axis in order to clean all the resistance. Subsequently the resistance is brought to the polishing station where the same operations described above are carried out. At the end of the cleaning phase, the resistance is sent to the discharge hopper 12.
Da quanto detto risulta chiaramente che il procedimento di pulitura secondo l’invenzione presenta numerosi vantaggi ed in particolare: From what has been said it is clear that the cleaning process according to the invention has numerous advantages and in particular:
- presenta un costo ridotto rispetto aH’impianto di elettropulitura, - has a reduced cost compared to the electro-cleaning system,
- non presenta problemi di inquinamento ambientale in quanto i residui dei solidi vengono scaricati come rifiuti solidi urbani, - it does not present problems of environmental pollution as the residues of the solids are discharged as solid urban waste,
- consente di effettuare una affidabile rifinitura grazie all utilizzo delle fibre sintentiche e del materiale abrasivo che viene continuamente sostituito, - si presta ad una produzione automatizzata e quindi ad elevata produzione. - it allows to carry out a reliable finishing thanks to the use of synthetic fibers and abrasive material which is continuously replaced, - it lends itself to an automated production and therefore to high production.
Nell’esempio descritto si è fatto riferimento ad un impianto che lavora in modo automatico su una resistenza rettilinea. Tale procedimento si presta però ad essere effettuato anche in modo manuale, cioè sottoponendo le singole resistenze ad un operazione manuale di pulitura meccanica, così come ad essere effettuato sia in modo automatico che manuale su una resistenza già finita. In the example described, reference was made to a system that works automatically on a straight resistance. However, this procedure can also be carried out manually, ie by subjecting the individual resistances to a manual mechanical cleaning operation, as well as to be carried out both automatically and manually on an already finished resistor.
La presente invenzione è stata illustrata e descritta in una sua preferita forma di realizzazione, ma si intende che varianti esecutive potranno ad essa in pratica apportarsi, senza peraltro uscire dall ambito di protezione del presente brevetto per invenzione industriale. The present invention has been illustrated and described in a preferred embodiment thereof, but it is understood that executive variations may be applied to it in practice, without however departing from the scope of protection of the present patent for industrial invention.
