Abstract:
A collector for removing a plating wax from a waxed component, the collector comprising:a process tank filled with a heated wax remover solution into which the waxed component is fully immersed and whereby the wax is removed from the component and floats on top of the remover solution, said wax remover solution and wax floating on top of it overflowing to a predetermined first level; a wax separator tank adjacent and operatively connected to the process tank for receiving said overflow of remover solution and floating wax, the floating wax decanting therein and forming a decanted wax layer floating above a level of wax remover solution lower than said first level, the decanted wax layer overflowing once it has piled up to a predetermined second level lower than the first level; a circulating pump operatively connected to the process tank and the wax separator tank for pumping the wax remover solution from the wax separator tank back to the process tank; a level controller operating with microwaves, the level controller being operatively connected to the wax separator tank for monitoring the level of remover solution below the decanted wax layer, the level controller comparing the level of remover solution with a preset level lower than the second level; and a chemical pump operatively connected to a reservoir of supplemental wax remover solution and to the wax separator tank and/or to the process tank, the chemical pump being further operatively connected to and controlled by the level controller in order to maintain the level of wax remover solution close to the preset level.
