DISPOSITIVO DI FILTRAGGIO PER LIQUIDO LIQUID FILTERING DEVICE
DESCRIZIONE DELL'INVENZIONE DESCRIPTION OF THE INVENTION
La presente invenzione si inquadra nel settore dei dispositivi di depurazione, in particolare si riferisce ad un dispositivo di filtraggio per liquido impiegato per filtrare l’acqua in macchine da caffè ad uso professionale e domestico. The present invention is part of the purification devices sector, in particular it refers to a liquid filtering device used to filter water in coffee machines for professional and domestic use.
I dispositivi noti per il filtraggio dell’acqua in una macchina da caffè sono costituiti da un involucro cilindrico alloggiale le resine e collegato tra la rete idrica e la pompa della macchina da caffè. The known devices for filtering water in a coffee machine consist of a cylindrical casing housing the resins and connected between the water supply and the coffee machine pump.
Tali dispositivi di filtraggio, per resistere alla pressione a cui vengono sottoposti, presentano uno spessore elevato delle pareti dell’involucro ed inoltre contengono ridotte quantità di resina, circa 3 litri, che permettono autonomia di filtraggio limitata dell’acqua, circa 4000 litri, e garantiscono un filtraggio dell’acqua per circa 1 anno. These filtering devices, in order to resist the pressure to which they are subjected, have a high thickness of the walls of the casing and also contain small quantities of resin, about 3 liters, which allow limited autonomy of filtering of the water, about 4000 liters, and guarantee water filtration for about 1 year.
Questi dispositivi noti possono altresì essere collegati ad apparecchi per l’erogazione di acqua del tipo lava tazze o lavandini in genere. These known devices can also be connected to water dispensing devices such as cup washers or sinks in general.
II principale svantaggio dei dispositivi noti risiede nel fatto che lavorano sotto pressione, e presentano quindi pareti aventi elevati spessori, e che contengono quantitativi limitati di resina. The main disadvantage of known devices lies in the fact that they work under pressure, and therefore have walls having high thicknesses, and which contain limited quantities of resin.
Un ulteriore svantaggio risiede nella necessità di sostituire frequentemente le resine che comporta quindi costi di manutenzione elevati. A further disadvantage lies in the need to frequently replace the resins which therefore entails high maintenance costs.
Lo scopo principale della presente invenzione è quello di proporre un dispositivo di filtraggio per liquido che possa contenere una maggiore quantità di resine a parità di ingombri. The main object of the present invention is to propose a liquid filtering device that can contain a greater quantity of resins with the same overall dimensions.
Un ulteriore scopo della presente invenzione è quello di aumentare la durata del dispositivo senza manutenzione e quindi di ridurre i costi di gestione. A further object of the present invention is to increase the life of the device without maintenance and therefore to reduce management costs.
Altro scopo è quello di proporre un dispositivo che lavori a bassa pressione. Le caratteristiche dell'invenzione sono nel seguito evidenziate con particolare riferimento agli uniti disegni in cui: Another purpose is to propose a device that works at low pressure. The characteristics of the invention are highlighted below with particular reference to the accompanying drawings in which:
- la figura 1 illustra una sezione del dispositivo oggetto della presente invenzione; Figure 1 illustrates a section of the device object of the present invention;
- la figura 2 illustra un particolare del dispositivo di figura 1 in una condizione di carico; Figure 2 illustrates a detail of the device of Figure 1 in a load condition;
- la figura 3 illustra un particolare del dispositivo di figura 1 in una condizione di chiusura. Figure 3 illustrates a detail of the device of Figure 1 in a closed condition.
Con riferimento alle figure da 1 a 3, con 1 viene indicato un dispositivo di filtraggio per liquido 2, preferibilmente per l’acqua utilizzata nelle macchine da caffè, note e non illustrate. With reference to figures 1 to 3, 1 indicates a filtering device for liquid 2, preferably for the water used in coffee machines, known and not illustrated.
Nella preferita forma di realizzazione il dispositivo di filtraggio 1 per liquido 2, o in alternativa per diversi liquidi 2, è costituito da un contenitore 3 cilindrico con una parete inferiore di fondo ed una parete superiore tra loro raccordate ed unite mediante una parete laterale. In the preferred embodiment, the filtering device 1 for liquid 2, or alternatively for different liquids 2, consists of a cylindrical container 3 with a bottom bottom wall and an upper wall joined together and joined by a side wall.
La parete superiore del contenitore 3 reca sia un’apertura 4 per l’accesso all’interno del contenitore 3, sia un condotto d’uscita 8 del liquido 2; mentre sulla parete laterale, in prossimità della parete superiore è presente un condotto d’ingresso 6 del liquido 2 nel contenitore 3. The upper wall of the container 3 has both an opening 4 for access to the inside of the container 3, and an outlet duct 8 for the liquid 2; while on the side wall, near the upper wall, there is an inlet duct 6 for the liquid 2 in the container 3.
I condotti d’ingresso 6 e di uscita 8 sono di tipo passante attraverso le pareti del contenitore 3. The inlet 6 and outlet 8 ducts are of the type passing through the walls of the container 3.
II contenitore 3, al suo interno, è suddiviso in due porzioni mediante un setto permeabile 9, disposto trasversalmente rispetto allo sviluppo verticale del contenitore 3 in modo pressoché parallelo alla parete di fondo ed a quella superiore. The container 3, inside it, is divided into two portions by means of a permeable septum 9, arranged transversely with respect to the vertical development of the container 3 almost parallel to the bottom and upper walls.
Il volume interno del contenitore 3, delimitato superiormente dal setto permeabile 9, costituisce una porzione inferiore 30 che ospita un quantitativo predeterminato di resine 5, mentre il volume interno del contenitore 3 delimitato inferiormente dal setto permeabile 9 costituisce una porzione superiore 31 priva di resina al suo interno. The internal volume of the container 3, delimited at the top by the permeable septum 9, constitutes a lower portion 30 which houses a predetermined quantity of resins 5, while the internal volume of the container 3 delimited at the bottom by the permeable septum 9 constitutes an upper portion 31 devoid of resin. inside.
Il setto permeabile 9 presenta dei fori passanti 10 aventi un diametro inferiore alla dimensione caratteristica dei granuli delle resine 5 in modo tale da impedirne il passaggio e quindi confinare le resine 5 all’interno della porzione inferiore 30. The permeable septum 9 has through holes 10 having a diameter smaller than the characteristic size of the granules of the resins 5 in such a way as to prevent their passage and therefore confine the resins 5 within the lower portion 30.
All’interno della porzione superiore 31 è presente un mezzo a valvola 20 fissato in prossimità dell’estremità interna del condotto d’ingresso 6. Inside the upper portion 31 there is a valve means 20 fixed near the internal end of the inlet duct 6.
II mezzo a valvola 20 comprende un involucro che è vincolato al condotto di ingresso 6 ed a cui è fissato un tubo 13 terminante nella porzione inferiore 30 ed attraversante il setto permeabile 9. The valve means 20 comprises a casing which is connected to the inlet conduit 6 and to which a tube 13 terminating in the lower portion 30 and passing through the permeable partition 9 is fixed.
Il tubo 13 è dotato di un primo mezzo a filtro 14 in corrispondenza della sua estremità libera posta nella porzione inferiore 30. The tube 13 is equipped with a first filter means 14 at its free end located in the lower portion 30.
II condotto d’uscita 8 è dotato di un secondo mezzo a filtro 15 in corrispondenza dell’estremità libera alloggiata nella porzione superiore 31 . The outlet duct 8 is equipped with a second filter means 15 at the free end housed in the upper portion 31.
Il mezzo a valvola 20 presenta esternamente un’asta 21 ad una cui estremità è vincolato un galleggiante 22 mentre la restante estremità è incernierata all’interno del mezzo a valvola 20, in prossimità della bocca d’erogazione 7. L’asta 21 è provvista di un mezzo a tappo 23, posto in prossimità dell’estremità incernierata. Il mezzo a tappo 23 presenta una forma atta a garantire una chiusura a tenuta della bocca d’erogazione 7 impedendo il passaggio del liquido 2 in una condizione di chiusura C. The valve means 20 externally has a rod 21 at one end of which a float 22 is constrained while the remaining end is hinged inside the valve means 20, near the delivery mouth 7. The rod 21 is provided of a plug means 23, placed in proximity to the hinged end. The cap means 23 has a shape suitable to ensure a tight closure of the delivery mouth 7 preventing the passage of the liquid 2 in a closed condition C.
Nella preferita forma di realizzazione, il dispositivo 1 per liquido 2 è installato a valle della rete di distribuzione idrica ed a monte di una pompa per macchine per la produzione di caffè. In the preferred embodiment, the device 1 for liquid 2 is installed downstream of the water distribution network and upstream of a pump for coffee making machines.
Il funzionamento del dispositivo 1 prevede inizialmente l’introduzione di una definita quantità di resine 5 nel contenitore 3 attraverso l’apertura 4 ed al di sotto del setto permeabile 9. The operation of the device 1 initially provides for the introduction of a defined amount of resins 5 into the container 3 through the opening 4 and below the permeable septum 9.
L’apertura 4 consente altresì l’accesso all’interno del contenitore 3 per il controllo e/o la sostituzione periodica delle resine 5. The opening 4 also allows access to the inside of the container 3 for checking and / or periodic replacement of the resins 5.
Il liquido 2 fluisce all’interno del contenitore 3 tramite il condotto d’ingresso 6, e il suo afflusso è regolato dal mezzo a valvola 20. The liquid 2 flows inside the container 3 through the inlet duct 6, and its inflow is regulated by the valve means 20.
In corrispondenza di una condizione di carico A il galleggiante 22, atto a galleggiare sul pelo libero del liquido 2 all’interno del contenitore 3, mantiene abbassata l’asta 21 così da attuare il disimpegno della bocca d’erogazione 7 da parte del mezzo a tappo 23 e consentire il flusso di liquido 2 all’interno del contenitore 3 attraverso il condotto di entrata 6, l’involucro del mezzo a valvola 20, il tubo 13 ed il primo mezzo a filtro 14. In correspondence with a load condition A, the float 22, able to float on the free surface of the liquid 2 inside the container 3, keeps the rod 21 lowered so as to effect the disengagement of the delivery mouth 7 by the means a plug 23 and allow the flow of liquid 2 inside the container 3 through the inlet conduit 6, the casing of the valve means 20, the tube 13 and the first filter means 14.
Quindi, il liquido 2 passa dal mezzo a valvola 20 alla porzione inferiore 30 in contatto con la resina 5 e quindi arriva alla porzione superiore 31 passando per il setto permeabile 9 che, in ogni caso, impedisce alla resina di raggiungere la porzione superiore 31. Then, the liquid 2 passes from the valve means 20 to the lower portion 30 in contact with the resin 5 and then reaches the upper portion 31 passing through the permeable septum 9 which, in any case, prevents the resin from reaching the upper portion 31.
All’aumentare del livello di liquido 2 all’interno del contenitore 3, in particolare nella porzione superiore 31 , l’asta 21 viene fatta innalzare dal galleggiante 22 ed il mezzo a tappo 23 si avvicina progressivamente alla bocca d’erogazione 7 fino al punto di tapparla e bloccare conseguentemente il flusso di liquido 2 all’interno del contenitore 3 in corrispondenza della condizione di chiusura C. Il liquido 2 viene aspirato dalla pompa della macchina da caffè ed esce dal contenitore 3 attraverso il secondo mezzo a filtro 15 ed il condotto d’uscita 8. Durante l’aspirazione del liquido 2 da parte della pompa il livello dello stesso diminuisce all’interno del contenitore 3 facendo abbassare il galleggiante 22 e quindi disimpegnando la bocca di erogazione 7 da parte del mezzo a tappo 23 e consentendo nuovamente il flusso di liquido 2 all’interno del contenitore 3 fino al raggiungimento del livello corrispondente alla condizione di chiusura C. As the level of liquid 2 inside the container 3 increases, in particular in the upper portion 31, the rod 21 is made to rise by the float 22 and the cap means 23 progressively approaches the delivery mouth 7 up to the point to plug it and consequently block the flow of liquid 2 inside the container 3 in correspondence with the closed condition C. The liquid 2 is sucked by the pump of the coffee machine and exits from the container 3 through the second filter means 15 and the duct outlet 8. During the suction of the liquid 2 by the pump, the level of the same decreases inside the container 3 causing the float 22 to lower and therefore disengaging the delivery mouth 7 by the cap means 23 and allowing again the flow of liquid 2 inside the container 3 until the level corresponding to the closed condition C is reached.
Il vantaggio principale della presente invenzione è quello di fornire un dispositivo di filtraggio per liquido che possa contenere una maggiore quantità di resine a parità di ingombri. The main advantage of the present invention is that of providing a liquid filtering device that can contain a greater quantity of resins with the same overall dimensions.
Un ulteriore vantaggio della presente invenzione è quello di aumentare la durata del dispositivo senza manutenzione e quindi di ridurre i costi di gestione. Altro vantaggio è quello di fornire un dispositivo che lavora a bassa pressione. A further advantage of the present invention is to increase the life of the device without maintenance and therefore to reduce the operating costs. Another advantage is to provide a device that works at low pressure.
