Definitions

the invention relates to devices for environmental protection to minimize the carry-over of treatment solutions in the rinsing and / or waste water circuit in the galvanic and / or chemical surface treatment of mass parts in submersible drums; after lifting the immersion drum from the treatment bath, the treatment solution is returned to the treatment bath by means of a locking and drainage system.
Methods are known in which compressed air and / or vacuum systems are intended to separate the treatment solution from the goods and the drum body. Methods are also known in which the submersible drums are sprayed with water in order to dilute the treatment solutions.
FIG. 1 shows a side view of the basic structure of a galvanic drum system, the details of which are assumed to be known.
FIG. 7 shows an example of the arrangement of the locking and drainage device on the cover of a submersible drum.
the immersion drum (1) is rotated in direction (B) by means of a rotary drum drive (16), the goods and the treatment solution can no longer slide off the inner jacket of the immersion drum (1) , Goods and treatment solution are taken through the locking bar (2) and the drainage bar (3); The treatment solution is forcibly separated from the immersion drum (1) via the drainage strip (3).
a drip tray (15) ensures that the emerging treatment solution is also separated from the outer jacket of the immersion drum (1).
the rotary movement of the immersion drum (1) can take place continuously or in order to prevent the treatment solution from overflowing via the blocking and drainage device.
the hole diameter (5) of the perforation of the drum jacket (4) is usually not sufficient to separate the treatment solution quickly and with high efficiency from the immersion drum (1).
the part of the drum jacket (4) that belongs to the drainage channel (DK) is provided with large openings (6). Furthermore, the outflow behavior of the treatment solution from the drainage channel (DK) can be improved through openings (7) on the two end faces (8) and (8 ') of the immersion drum (1).
the drum cover (4 ') can easily be equipped with a drainage channel (DK), or can be exchanged for one with a drainage channel (DK).
the immersion drums (1) are transported through the treatment baths (13) by the station (14) by means of a transport system (10) to which a collecting trough (11) which can be extended on two sides can be attached.
a transport system (10) to which a collecting trough (11) which can be extended on two sides can be attached.
the treatment solution still dripping from the immersion drum (1) can still be collected in the collecting trough (11).
the collecting trough (11) is returned to the treatment bath (13P) one or the other side extended from the transport system (10).
the treatment solution collected in the drip pan (11) is drained into the treatment bath (13P) via the controllable solenoid valve (12).
