Abstract

Inventia se refera la un procedeu de reglare, în mod continuu, a malaxarii pastelor destinate fabricarii aglomerarilor de carbon, într-un malaxor prevazut cu dinti ficsi si un arbore, de asemenea prevazut cu dinti, care efectueaza o miscare de rotatie combinata cu o miscare înainte-înapoi, si având clapete actionate de motor care controleaza iesirea pastei de carbon. La fiecare ciclu de rotatie a arborelui se masoara, prin esantionare, intensitatea absorbita de motor pentru anumite pozitii particulare ale arborelui în miscarea sa înainte-înapoi, se compara intensitatea cu o valoare de consemn, eventual corectata în functie de nivelul acestei intensitati fata de anumite praguri predeterminate, si se introduce aceasta valoare corectata într-un regulator care determina, pentru fiecare cilcu, gradul de deschidere a clapetelor de iesire.The invention relates to a process for continuously adjusting the mixing of the pastes for the manufacture of carbon agglomerates in a fusible teeth mixer and a shaft also provided with teeth which performs a rotation motion combined with a movement back and forth, and having engine driven valves controlling the carbon footprint. At each shaft rotation cycle, by sampling, the engine power absorbed by the engine for certain particular shaft positions in its forward / backward movement, the intensity is compared with a value recorded, possibly corrected depending on the level of this intensity relative to certain predetermined thresholds, and this corrected value is entered into a regulator that determines for each cylinder the degree of opening of the output flaps.
