Abstract
Prezenta inventie se refera la o pompa cu melc pentru transportarea de materiale solide, cu granulatie fina, inclusiv sub forma de praf, antrenate de un mijloc corespunzator, prevazuta cu o carcasa dotata cu o pîlnie de intrare precum si cu una de evacuare a materialului într-un spatiu în care se afla o presiune relativ ridicata, împingerea fiind realizata de catre un arbore care este prevazut cu spire elicoidale în genul unei constructii melcate, arborele fiind situat în carcasa mentionata. în acest scop arborele este sustinut, la ambele capete, de cîte un lagar protejat de niste garnituri, în sine cunoscute, arborele fiind prevazut cu spire melcate care, în zona dinspre iesire, nu sunt fixate direct pe aceasta, ci pe un manson, deasupra partii de început a spirei melcate fiind prevazuta pîlnia de alimentare, iar imediat înaintea pîlniei de evacuare fiind amplasat un ventil de retinere de tip unisens. Pe arbore, în regiunea spatiului de evacuare a materialului, imediat dupa ventilul de retinere susmentionat, fiind fixat, demontabil, un manson care are, la capatul sau anterior, o zona cu diametru marit, care devine, în mod treptat, conica înspre partea de iesire, astfel înît materialul transportat în timpul pomparii sa fie comprimat. Ventilul de retinere este constituit dintr-un element inelar si o pîrghie care poate pendula în jurul unei axe oscilante, elementul inelar înconjurînd arborele melcat din regiunea respectiva, pentru limitarea miscarii de deschidere a ventilului de retinere fiind prevazut un opritor reglabil. Pompa mai dispune, în continuarea mansonului mentionat mai sus de un manson anterior, prevazut cu o spira melcata, care
