L'impianto à ̈ inoltre collegato ad un dispositivo di comando e controllo, non illustrato per semplicità di rappresentazione, atto a governare il funzionamento e le interazioni dei componenti di detto impianto. The plant is also connected to a command and control device, not illustrated for simplicity of representation, designed to govern the operation and interactions of the components of said plant.
Il procedimento per la produzione, mediante l'impianto sopra descritto, di pigmenti particolarmente adatti all'impiego nell'industria conciaria comprende una iniziale fase di carico in ciascun serbatoio 101, 101', di predeterminate quantità di sostanze dall'almeno un ingresso di serbatoio 120, 120', e/o dal boccaporto 108, 108', e/o con l’ausilio del dispositivo di somministrazione di additivi in polvere 119. Tali sostanze sono diverse, in natura e quantità , a seconda del particolare pigmento che si desidera produrre tramite il suddetto impianto. Alla iniziale fase di carico segue una fase di riflusso in cui i miscugli di sostanze contenuti in ciascun serbatoio 101, 101', vengono fatti rifluire, attraverso il complesso di condotti di processo 128, nel medesimo serbatoio di provenienza, con sostanziale ricircolo, e, successivamente, con o senza processo di raffinazione, fatti transitare da un serbatoio all'altro, rispettivamente. Prima che si concluda la suddetta fase di riflusso, vengono prelevate determinate quantità dei suddetti miscugli tramite i dispositivi di campionamento 122, 122'. The process for the production, by means of the plant described above, of pigments particularly suitable for use in the tanning industry comprises an initial phase of loading into each tank 101, 101 ', of predetermined quantities of substances from the at least one tank inlet 120, 120 ', and / or from the hatch 108, 108', and / or with the aid of the device for administering powder additives 119. These substances are different in nature and quantity, depending on the particular pigment that is wishes to produce through the aforementioned plant. The initial loading phase is followed by a reflux phase in which the mixtures of substances contained in each tank 101, 101 ', are made to flow back, through the complex of process conduits 128, into the same original tank, with substantial recirculation, and, subsequently, with or without refining process, made to pass from one tank to another, respectively. Before the aforesaid reflux phase is completed, certain quantities of the aforesaid mixtures are taken by means of the sampling devices 122, 122 '.
Per mescolare i miscugli di sostanze presenti nei serbatoi 101, 101', vengono attivati i dispersori 104, 104', per un periodo di tempo variabile, ad una velocità tra 150 giri/min. e 700 giri/min.. To mix the mixtures of substances present in the tanks 101, 101 ', the dispersers 104, 104' are activated, for a variable period of time, at a speed between 150 rpm. and 700 rpm.
Dopo la fase di riflusso, dispersione e/o raffinazione, la composizione, ossia il pigmento, presente nei serbatoi 101, 101', viene prelevato dall'impianto attraverso una uscita di impianto 127 e sottoposto alle operazioni di imballaggio. After the reflux, dispersion and / or refining step, the composition, ie the pigment, present in the tanks 101, 101 ', is withdrawn from the plant through a plant outlet 127 and subjected to the packaging operations.
Terminato il prelievo, viene attivato l'ameno un dispositivo di lavaggio fisso 113, 113', per lavare e ripulire la parte interna dei serbatoi 101, 101'. Il fluido di lavaggio, ad esempio acqua, usato nei dispositivi di lavaggio fissi 113, 113', viene poi espulso dall'impianto mediante una uscita di impianto 127. At the end of the withdrawal, a fixed washing device 113, 113 'is activated to wash and clean the internal part of the tanks 101, 101'. The washing fluid, for example water, used in the fixed washing devices 113, 113 ', is then expelled from the plant by means of a plant outlet 127.
Naturalmente, fermo restando il principio del trovato, le forme di attuazione ed i particolari di realizzazione potranno ampiamente variare rispetto a quanto descritto ed illustrato, senza per questo uscire dall'ambito dell'invenzione. Naturally, the principle of the invention remaining the same, the forms of embodiment and details of construction may vary widely with respect to what has been described and illustrated, without thereby departing from the scope of the invention.
