Job: Cleaning of machine components for the production of technical films and packaging materials | Challenge: high cleanliness requirements and heavy soiling | Realisation: Automated cleaning system of the ROTOTRONIC® type with robot-controlled high-pressure water pre-cleaning | Process: diverse processes
PURIMA will soon be using an innovative continuous cleaning system to clean high-quality components from machines for the production of technical films
New order from us: For the international maintenance and repair plant of a German manufacturer of machines for the production of technical films and high-quality packaging materials, PURIMA has developed a unique facility conceptualised, which will be implemented in the coming months.
Previously, cleaning tests with original parts in our in-house technical centre had shown that the heavily soiled components that come into the maintenance plant from all over the world can be cleaned to the customer’s satisfaction only through a combination of different cleaning methods. Based on this, our specialists have designed a system that follows the proven PURIMA-ROTOTRONIC© process – continuous cleaning.
Robot cleans with high-pressure water pre
A special and essential feature of the plant? – In the first cleaning step, the components, which are used to pull the films through the production line and are regularly greased, with a robot with integrated rotating nozzle head and high water pressure up to to 1.500 bar pre-cleaned with city water. The integrated rotary nozzle head applies the components comprehensively and with great force. Pre-cleaning – like the subsequent treatment stages – takes place in a closed dip tank. Only then is further cleaning carried out using injection pressure flooding and ultrasound. Rinsing, the next treatment step for the components, is then also carried out by injection pressure flooding. Depending on the cleaning programme, the components are finally optionally preserved or directly ejected. Sustainability and cost-effectiveness also play an important role in the PURIMA system: To increase efficiency and conserve resources, the operator can, depending on the degree of soiling of the components to be cleaned, skip individual steps.
This ROTOTRONIC® cleaning system with robot-controlled pre-cleaning is new at PURIMA.
Professional preparation of cleaning media
Due to the high volume of contaminants —primarily baked-on grease—PURIMA also uses a so-called Sepatronic module to treat the cleaning media: Sinking contaminants are removed from the Sepatronic module’s collection tank via a screw conveyor, while floating contaminants are flushed from the surface of the collection tank and fed to a belt filter for further separation. Subsequently, smaller particles are separated using bag and cartridge filters. A vacuum evaporation system is used to recycle the high-pressure water from the pre-cleaning stage and to treat the rinse water. Over the weekend, during the cleaning system’s downtime, the used cleaning solution from the cleaning tank can also be automatically regenerated using ultrasound.
Incidentally, thanks to the interaction of the various techniques for treating the process liquids, the system works wastewater-free.
We are very pleased about this exciting new contract and will keep you up to date!
