Abstract
Distillation chamber for extracting solvent from sludge, in particular for dry-cleaning machines, having a bottom shaped like a half-cylinder with a horizontal axis. The bottom is provided, in a downward position, at one end, with an outlet for extracting dried sludge. A shaft is axially and rotatably mounted in the chamber and spatula-like sectors, suitable for stirring the sludge and for pushing it toward the outlet upon the rotation of the shaft, are fixed to the shaft itself.
Claims4
A distillation apparatus for removing dry-cleaning solvents from sludge, comprising:
- distillation chamber for containing the sludge, said distillation chamber comprising an upper portion and a lower portion, said lower portion having a semi-cylindrical shape with a horizontally arrangeable axis;
- means for heating the sludge inside said distillation chamber to evaporate solvents from the sludge;
- means for condensing and separating evaporated solvents;
- a rotatable shaft which is arranged inside said distillation chamber and parallel to said horizontally arrangeable axis;
- a plurality of sector elements which are rigidly connected to said rotatable shaft and which are provided with curved brush-like end portions, said curved brush-like end portions being arranged so as to scrape said lower portion of said distillation chamber upon rotation of said rotatable shaft, said sector elements being arranged in an inclined and mutually spaced manner on said rotatable shaft so as to push sludge inside said distillation chamber toward an end thereof upon rotation of said rotatable shaft;
- a sludge removing outlet provided at a bottom of said lower portion of said distillation chamber at said end thereof;
- means for sealingly closing said sludge removing outlet;
- and
- a shaped lip connected to said sludge removing outlet and extending downwardly from said bottom of said lower portion;
- and
- a sludge collecting bag which is removably fixable in a sealed manner about said shaped lip.
