DISPOSITIVO PER RIDURRE, IN UN GENERATORE DI CALORE, LA DISPERSIONE DI ENERGIA IN ATMOSFERA DEVICE TO REDUCE ENERGY DISPERSION IN THE ATMOSPHERE IN A HEAT GENERATOR

RIASSUNTO SUMMARY

Si descrive un dispositivo che: impedisce al calore accumulato in un generatore( per esempio un forno da pane, piuttosto che una caldaia da riscaldamento) , di andare disperso in atmosfera dopo che il bruciatore ha fatto raggiungere la temperatura voluta all’apparecchiatura. A device is described that: prevents the heat accumulated in a generator (for example a bread oven, rather than a heating boiler), from being dispersed into the atmosphere after the burner has made the equipment reach the desired temperature.

Esso impiega una serranda auto bilanciata , normalmente aperta , la chiusura avverrà mediante un filo a memoria di forma che una volta azionato porterà la serranda in posizione chiusa evitando la fuoriuscita del calore e di conseguenza risparmiando energia It uses a self-balanced shutter, normally open, closing will take place by means of a shape memory wire which, once activated, will bring the shutter to the closed position, avoiding the escape of heat and consequently saving energy.

TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION

La presente invenzione riguarda un dispositivo che permette di risparmiare energia e di conseguenza inquinare meno , impedendo al calore accumulato in un generatore, di fuoriuscire dalla canna fumaria . The present invention relates to a device which allows to save energy and consequently to pollute less, preventing the heat accumulated in a generator from escaping from the flue.

E’ risaputo che , un bruciatore per un corretto funzionamento ha bisogno di una certa depressione nel camino ,in modo che i gas combusti possano fuoriuscire senza creare danni alle persone( intossicazioni). It is well known that for a burner to function correctly it needs a certain depression in the chimney, so that the burnt gases can escape without causing harm to people (intoxication).

Detta depressione , resta presente nella canna fumaria anche quando il bruciatore sì ferma , cosi estrae il calore presente nei generatore raffreddandolo. Said depression remains present in the flue even when the burner stops, thus it extracts the heat present in the generator, cooling it.

Questo principio , pur essendo estremamente elementare e noto a tutti presenta l'inconveniente della grande dispersione di energia termica e di conseguenza un inquinamento inutile ( senza nessun beneficio ) This principle, although extremely elementary and known to all, has the drawback of the large dispersion of thermal energy and consequently unnecessary pollution (without any benefit)

Il presente trovato risolve detti inconvenienti , in quanto si impedisce che il calore venga aspirato dal camino bloccandolo con una serranda . The present invention solves said drawbacks, since the heat is prevented from being sucked in by the chimney by blocking it with a shutter.

Detto sistema è già conosciuto , solo che la sicurezza presenta qualche lacuna , visto che la serranda è comandata mediante motorizzazioni elettriche le quali possono subire danni, cosi da non poter garantire l'apertura totale della valvola , causando i danni già in precedenza visti. Said system is already known, except that the safety has some shortcomings, since the shutter is controlled by electric motors which can be damaged, so as not to be able to guarantee the total opening of the valve, causing the damage already seen previously.

L’innovazione presentata , rispetto al conosciuto non trova nessun ostacolo sull’apertura della serranda essendo la stessa auto bilanciata sempre aperta e comandata da un filo di basso spessore in metallo a memoria di forma che comanda la chiusura. The innovation presented, compared to the known, does not find any obstacle on the opening of the shutter being the same balanced car always open and controlled by a low thickness metal wire with shape memory that controls the closure.

Questi scopi , caratteristiche ed altri vantaggi della presente invenzione saranno ancora più chiari ed evidenti dalla successiva dettagliata descrizione , a titolo puramente esemplificativo e non limitativo della portata del trovato , facendo riferimento alle varie figure delle annesse tavole di disegni illustrativi , in cui: la Figura 1 mostra il dispositivo in questione, completo di : tubo di raccordo con annessa valvola a farfalla, scatola di contenimento meccanismo per l'apertura / chiusura , apparecchiatura elettronica e sistemi di sicurezza . These objects, characteristics and other advantages of the present invention will be even more clear and evident from the following detailed description, purely by way of example and not limiting the scope of the invention, with reference to the various figures of the accompanying tables of illustrative drawings, in which: Figure 1 shows the device in question, complete with: connection pipe with attached butterfly valve, containing box, opening / closing mechanism, electronic equipment and safety systems.

Nei forni o nelle caldaie, per produrre l’energia necessaria al fabbisogno, si utilizzano bruciatori a gas o a gasolio, i quali hanno bisogno di un camino per l’estrazione dei gas combusti , il quale sia per legge che per un corretto funzionamento deve creare una depressione nella camera di combustione. In ovens or boilers, gas or diesel burners are used to produce the energy necessary for the needs, which need a chimney for the extraction of the burnt gases, which both by law and for correct functioning must create a vacuum in the combustion chamber.

La depressione creata nella canna fumaria (camino) è sempre presente , sia che il bruciatore sia acceso o spento , quindi dal camino usciranno i residui della combustione quando il bruciatore è in funzione e aria calda quando invece è spento , causando un raffreddamento inutile e dannoso per l’impianto. The depression created in the flue (chimney) is always present, whether the burner is on or off, therefore the combustion residues will come out of the chimney when the burner is running and hot air when it is off, causing unnecessary and harmful cooling. for the plant.

Ipotizziamo di utilizzare il dispositivo per risparmiare energia in un forno da pane , dove, mediante un bruciatore per creare una temperatura , che una volta raggiunta ,un termostato fermerà lo stesso .contemporaneamente manderà un segnale alla scheda elettronica 6 del dispositivo per il risparmio energetico , la quale, darà corrente ( 24V) per un breve periodo al filo a memoria di forma 3 che scaldandosi si accorcerà di circa 15 mm e visto che lo stesso è bloccato al morsetto 8 farà ruotare l’alberino di comando valvola 1 . Detto alberino è provvisto di un tondino 9 che durante la rotazione , scivolando sulla costa anteriore del gancio di blocco valvola 2, prima lo spingerà indietro , poi verrà agganciato dallo stesso grazie alla forza di gravità , nel medesimo istante il tondino 9, azionerà il microinterruttore 5 die inibirà la partenza del bruciatore , inoltre toglierà la corrente che alimenta il filo a memoria di forma. Let's assume we are using the device to save energy in a bread oven, where, by means of a burner to create a temperature, which once reached, a thermostat will stop it. At the same time it will send a signal to the electronic board 6 of the energy saving device, which will give current (24V) for a short time to the shape memory wire 3 which, when heated, will shorten by about 15 mm and since it is locked to terminal 8 it will rotate the valve control shaft 1. Said shaft is provided with a rod 9 which during rotation, sliding on the front edge of the valve block hook 2, will first push it back, then it will be hooked by the same thanks to the force of gravity, at the same instant the rod 9 will activate the microswitch 5 days will inhibit the start of the burner and will also cut off the current that feeds the shape memory wire.

Ora con la valvola chiusa , si raggiungerà il fine preposto , cioè impedire che la depressione della canna fumaria, sottragga calore dal forno. Now with the valve closed, the intended purpose will be reached, that is to prevent the depression of the flue from removing heat from the oven.

Quando il termostato segnalerà che il forno ha bisogno di calore , darà un impulso alla scheda 6 la quale darà tensione (24 V ) al filo a memoria di forma 4 , che ritirandosi di circa 7mm sposterà , il gando 2, liberando il tondino 9, che facendo parte dell’alberino comando valvola, permetterà alla stessa di aprirsi senza l’ausilio di nessun automatismo, perché bilanciata in precedenza in modo che sia normalmente aperta. When the thermostat signals that the oven needs heat, it will give an impulse to the board 6 which will give voltage (24 V) to the shape memory wire 4, which, retracting by about 7mm, will move the knob 2, freeing the rod 9, which, being part of the valve control shaft, will allow it to open without the aid of any automatism, because it has been previously balanced so that it is normally open.

Detto movimento darà modo al tondino 9 di liberare il microinterruttore 5 permettendo la partenza del bruciatore. Said movement will allow the rod 9 to free the microswitch 5 allowing the burner to start.

Le prove effettuate, hanno dimostrato un notevole allungamento del tempo di pausa del bruciatore, dovuto alla non fuoriuscita del calore dalla canna fumaria, producendo un notevole risparmio energetico e di conseguenza un minor inquinamento. The tests carried out have shown a considerable lengthening of the burner pause time, due to the non-escape of heat from the flue, producing considerable energy savings and consequently less pollution.

Benché nei disegni e nella relativa descrizione dettagliata si sia indicato ,che il dispositivo per ridurre dispersione di energia in atmosfera , sia posto a monte della fonte di calore e potrà essere realizzato in diverse misure in funzione al camino , si deve infine comprendere che numerose modifiche , aggiunte , variazioni o sostituzioni di elementi potranno essere apportate alla presente invenzione, senza per questo uscire dal suo ambito di protezione , come risulta anche definito nelle annesse rivendicazioni. Although in the drawings and in the related detailed description it has been indicated that the device for reducing energy dispersion into the atmosphere is placed upstream of the heat source and can be made in different sizes depending on the chimney, it must finally be understood that numerous modifications , additions, changes or replacements of elements may be made to the present invention, without thereby departing from its scope of protection, as is also defined in the attached claims.
