Abstract
The present invention relates to a device for a distiller adapted to distil solvents for recovery of pure solvent from impure solvent, the solvent (2) being used for washing away residues of paint from spray guns. The distiller (1) includes an outer container (5) with a boiling chamber (8) which at the top has an opening (9) which can be tightly closed by a cover (10) and a flexible inner container (13) is provided in the boiling chamber (8), the flexible inner container (13) containing impure solvent to be distilled. A pipe means (20) is placed beside the flexible inner container (13) in order to allow solvent steam (7a), which is generated by boiling solvent in a lower space (19) beneath the flexible inner container (13), to pass from the lower space (19) into an upper space (16) having an outlet (17) and located above the flexible inner container (13) for preventing the solvent steam (7a) from lifting the flexible inner container (13) in the boiling chamber (8).
