Abstract
Apparecchiatura per pompare materiali solidi particellari che hanno un peso specifico apparente iniziale che è inferiore alla densità strutturale; è previsto un canale di circolazione (18) che ha un'entrata ed un'uscita e comprende: (I) un segmento di canale di circolazione di trascinamento anulare (11) formato tra un elemento di parete esterno fisso (14) e un elemento di parete interna circolare rotante (16); e (II) un segmento di canale rettilineo (18) formato tra una prima parte di parete piana e fissa (148) e una seconda parte di parete piana e fissa (182); nessuna sezione trasversale assiale del canale di circolazione (12) tra l'entrata e l'uscita è più piccola della sezione trasversale assiale in corrispondenza dell'entrata; un alimentatore rotante (13) è collegato al canale di circolazione (12) vicino alla sua entrata per compattare preliminarmente il materiale solido particellare che viene poi fatto passare attraverso il canale di circolazione (18) per aumentare sostanzialmente il peso specifico apparente ed evitare la fusione e/o la degradazione termica del materiale solido particellare quando passa attraverso il canale di circolazione (12).
