Description
D E S C R I Z I O N E DESCRIPTION
a corredo della domanda di brevetto per modello di utilità avente per titolo: "Piastra per macchine liofilizzatrici" accompanying the patent application for a utility model entitled: "Plate for freeze drying machines"
La presente innovazione concerne una piastra per macchine liofilizzatrici. The present invention relates to a plate for freeze drying machines.
Sono note piastre, da posizionare all’interno di macchine liofilizzatrici, costituite da due lamiere parallele in acciaio collegate fra loro in corrispondenza dei bordi da un telaio a formare una camera chiusa, provvista di condotti di ingresso e di uscita, all’interno della quale circola un fluido diatermico raffreddato/riscaldato proveniente da un impianto frigorifero/riscaldamento. Plates are known, to be positioned inside freeze drying machines, consisting of two parallel steel sheets connected to each other at the edges by a frame to form a closed chamber, provided with inlet and outlet ducts, inside which a cooled / heated diathermic fluid circulates from a refrigeration / heating system.
Ad una delle due lamiere sono saldati una pluralità di elementi tubolari paralleli fra loro. A plurality of parallel tubular elements are welded to one of the two sheets.
Detti elementi tubolari sono disposti sfalsati gli uni rispetto agli altri nel senso che essi sono alternatamente collegati ad una prima parete del telaio perimetrale e distanziati dalla parete opposta e collegati alla parete opposta e distanziati dalla prima. Said tubular elements are arranged staggered with respect to each other in the sense that they are alternately connected to a first wall of the perimeter frame and spaced from the opposite wall and connected to the opposite wall and spaced from the first.
In questo modo si forma un percorso a zig zag formante canali paralleli di passaggio del fluido diatermico che assorbe calore per convenzione raffreddando gli oggetti posti sulle piastre. In this way a zigzag path is formed, forming parallel channels for the passage of the diathermic fluid which absorbs heat by convention, cooling the objects placed on the plates.
Tali piastre si sono dimostrate tuttavia suscettibili di essere perfezionate per quanto riguarda il miglioramento dello scambio termico nello spazio all’interno degli elementi tubolari che formano il percorso a zig zag. Infatti in questi elementi il fluido è sostanzialmente stagnante per cui lo scambio termico con le piastre avviene solo per conduzione. However, these plates have proved capable of being improved as regards the improvement of the heat exchange in the space within the tubular elements that form the zigzag path. In fact in these elements the fluid is substantially stagnant so that the heat exchange with the plates occurs only by conduction.
Secondo l'innovazione tale inconveniente viene eliminato con una piastra per macchine liofilizzatrici comprendente due lamiere affacciate parallele collegate da un telaio perimetrale e provvista di condotto di ingresso e di uscita di un fluido diatermico raffreddato/riscaldato, all'interno della camera formata da dette lamiere e da detto telaio essendo previsti una pluralità di profilati paralleli fra loro che formano canali di flusso del fluido diatermico, caratterizzata dal fatto che detti profilati hanno sezione ad Ω e sono interessati in corrispondenza di una loro estremità vincolata al telaio di un’apertura che forma un passaggio per il fluido diatermico all'interno della cavità del profilato ad Ω. According to the innovation, this drawback is eliminated with a plate for freeze-drying machines comprising two parallel facing sheets connected by a perimeter frame and provided with an inlet and outlet duct for a cooled / heated diathermic fluid, inside the chamber formed by said sheets. and from said frame being provided a plurality of parallel profiles which form flow channels of the diathermic fluid, characterized in that said profiles have an Ω section and are involved in correspondence with one of their ends fixed to the frame of an opening which forms a passage for the diathermic fluid inside the Ω profile cavity.
La presente innovazione viene qui di seguito ulteriormente chiarita con riferimento alle allegate tavole di disegni in cui: The present innovation is further clarified below with reference to the attached drawing tables in which:
la figura 1 mostra in vista prospettica interrotta una piastra secondo l’innovazione, e Figure 1 shows in an interrupted perspective view a plate according to the innovation, e
la figura 2 mostra in vista prospettica un profilato. Figure 2 is a perspective view of a section bar.
Come si vede dalle figure la piastra secondo l’innovazione è indicata genericamente con 2 e comprende sostanzialmente una lamiera metallica superiore 4 ed una lamiera inferiore 6 parallele fra loro e collegate da un telaio formato da quattro barre 8, 8’ 10, 10’, a sezione sostanzialmente quadrata, a formare una camera 12. As can be seen from the figures, the plate according to the invention is generically indicated with 2 and substantially comprises an upper metal plate 4 and a lower plate 6 parallel to each other and connected by a frame formed by four bars 8, 8 '10, 10', substantially square section, to form a chamber 12.
La camera 12 è provvista, in corrispondenza di un’estremità dei lati 8,8', di due condotti coassiali di ingresso 14 e di uscita 16 rispettivamente. The chamber 12 is provided, at one end of the sides 8.8 ', with two coaxial inlet ducts 14 and outlet 16 respectively.
Alle barre 8, 8’, 10 e 10’ sono vincolati una pluralità di profilati 18 paralleli fra loro aventi sezione ad Ω con asse perpendicolare all’asse dei condotti 14 e 16. The bars 8, 8 ', 10 and 10' are constrained by a plurality of sections 18 parallel to each other having an Ω section with an axis perpendicular to the axis of the ducts 14 and 16.
I profilati 18, che hanno altezza uguale all'altezza della camera 12, hanno lunghezza minore della lunghezza delle barre 8, 8' e formano un’apertura 20 fra la loro estremità libera e le barre 10, 10' affacciata. Essi sono alternatamente vincolati a l’una e all’altra barra 10, 10’ a formare un percorso a zig zag di canali 22 paralleli fra loro. The sections 18, which have a height equal to the height of the chamber 12, have a length shorter than the length of the bars 8, 8 'and form an opening 20 between their free end and the facing bars 10, 10'. They are alternately linked to one and the other bar 10, 10 'to form a zigzag path of channels 22 parallel to each other.
Inoltre l'estremità di ciascun profilato 18, che è vincolata alla barra 10' presenta un intaglio a 45° rispetto all’asse longitudinale in modo da formare con la barra stessa 10' un passaggio 24 verso l'interno della porzione ad U 26 del profilato ad Ω 18. Furthermore, the end of each section 18, which is constrained to the bar 10 'has a notch at 45 ° with respect to the longitudinal axis so as to form with the bar 10' a passage 24 towards the inside of the U-shaped portion 26 of the Ω profile 18.
In questo modo il fluido diatermico che entra attraverso il condotto 14 nella camera 12 si distribuisce sia lungo i canali 22 sia all'interno del profilato 18, per uscire dall'altra estremità, così da creare anche in questo caso uno scambio per convenzione con il profilato e conseguentemente con le lamiere. In this way the diathermic fluid that enters through the duct 14 into the chamber 12 is distributed both along the channels 22 and inside the profile 18, to exit from the other end, so as to create also in this case an exchange by convention with the profiled and consequently with the sheets.
In una variante realizzativa non rappresentata nei disegni l'apertura è costituita da un foro praticato nei tratti verticali del profilato. In a variant embodiment not shown in the drawings, the opening consists of a hole made in the vertical portions of the section.
