Abstract
The present invention relates to a measuring device at recovery devices (1). The recovery device (1) comprises a container (11) for pure solvent (10). The measuring device (12) includes a capacitive detector (13) which is provided to signal if the container (11) is not empty nor substantially emtpy when one tries to start operation of the recovery device (1) for recovering pure solvent (10).
Claims10
Measuring device at recovery devices (1),
- wherein the recovery device (1) is designed for location locally in workshops or similar premises, in which contaminated or impure solvent (4) originates because objects in said workshops or similar premises are cleaned by means of a solvent, and
- wherein the recovery device (1) comprises a container (3) for contaminated or impure solvent (4), a heating device (5) for heating contaminated solvent (4) present in said container (3), such that solvent vapours (6) are generated in the container (3), and a condenser (8) for condensing solvent vapours (6) which are fed from said container (3) to the condenser (8) for condensing the solvent vapours (6) therein to pure solvent (10) which is fed to a container (11) for pure solvent (10), characterized in
- that the measuring device (12) includes a capacitive detector (13) which is provided to generate a signal if the container (11) for pure solvent (10) is not empty nor substantially empty when one attempts to start operation of the recovery device (1) for the recover of solvent (10).
Measuring device according to any preceding claim, characterized in
- that the capacitive detector (13) includes an elongated, tubular outer member (14) and, provided longitudinally therein, an inner member (15),
- that the outer member (14) is provided in or lowerable into the container (11) for pure solvent (10) such that lower parts (17, 18) of the outer and inner members (14, 15) are located at the bottom (19) of the container (11), and
- that the capacitive detector (13) is provided to measure the capacitance primarily between said lower parts (17, 18) of said outer and inner members (14, 15).
Measuring device according to any preceding claim, characterized in that the capacitive detector (13) generates a signal to a viewing screen or display (29) to indicate with text and/or symbols that the container (11) for pure solvent (10) is not empty nor substantially empty when one tries to start operation of the recovery device (1) if the container (11) is not empty nor substantially empty.
Measuring device according to any preceding claim, characterized in
- that the recovery device (1), the container (3) for contaminated solvent (4) and the condenser (8) are located beside each other in an outer casing (2),
- that beneath the container (3) for contaminated solvent (4), the outer casing (2) defines a space (33) for the container (11) for pure solvent (10), and
- that the container (11) for pure solvent (10) is removable from said space (33) for emptying it of its contents.
Measuring device according to any preceding claim, characterized in
- that the recovery device (1) is a mobile device which when required can be moved by hand in the workshop or other premises in which the contaminated solvent (4) originates, and
- that the recovery device (1) e.g. is adapted for recovering solvent in the form of pure thinner from such contaminated thinner which has originated from cleaning of spray guns for painting objects, e.g. motor vehicles.
