Abstract:
Apparatus for carrying out a process for producing a fresh wiping solution composed of at least softened water and for treating the wiping solution contaminated by the inks of one or more intaglio printing machines, said apparatus being composed of at least one unit for the production of fresh wiping solution (1) and at least one wiping tank (2), which receives the fresh wiping solution and in which the fresh solution is contaminated by the inks, and comprising a first tank for used wiping solution (3) collecting the solution from the wiping tank (2), a second tank (4) which receives the wiping solution from the first tank (3) and a chemical agent, in which the chemical agent reacts with the solution to produce a solution and sedimented ink, a tank for separation by settling (5) receiving the solution and the sedimented ink, a concentrated solution tank (6) connected to the tank for separation by settling (5) receiving the concentrated solution and the sedimented ink which result from the separation by settling, a filtration system (7) filtering the concentrated solution and the sedimented ink, a recycling tank (8) receiving the clean solution leaving the tank for separation by settling (5) and the clean solution resulting from the filter press (7), said recycling tank (8) being connected to the fresh wiping solution production line, and pumping and transfer means for transferring said solutions from one tank to another.
