Title (EN) FILTER ARRANGEMENT, INDUSTRIAL CLEANING INSTALLATION WITH THAT FILTER ARRANGEMENT AND CORRESPONDING PROCESS
(FR) AGENCEMENT DE FILTRE, INSTALLATION DE NETTOYAGE INDUSTRIELLE AYANT L'AGENCEMENT DE FILTRE, ET PROCÉDÉ CORRESPONDANT
Abstract:
(EN) The invention relates to an industrial installation and process for cleaning workpieces, in particular for cleaning components of engines and transmission components using a cleaning liquid. The industrial installation comprises a first filter which is a backwash filter (17) for receiving contaminated cleaning liquid, a second filter (18) arranged for receiving backwashed contaminated cleaning liquid from the backwash filter (17), and for removing solid matter, e.g. chips, from the contaminated cleaning liquid, and an oil separator (21) arranged for receiving contaminated cleaning liquid and for removing oil from the contaminated cleaning liquid, whereby the oil separator (21) is fluidly connected to the second filter (18) and arranged for receiving the contaminated cleaning liquid directly from the second filter (18). The arrangement of the oil separator (21) directly following the second filter improves the filtering efficiency of the system by reducing the flow path distances of the contaminated cleaning liquid.
(FR) L'invention concerne une installation industrielle et un procédé pour le nettoyage de pièces, en particulier pour le nettoyage d'éléments de moteurs et d'éléments de transmission à l'aide d'un liquide de nettoyage. L'installation industrielle comprend un premier filtre qui est un filtre à lavage à contre-courant (17) pour recevoir un liquide de nettoyage contaminé, un second filtre (18) conçu pour recevoir le liquide de nettoyage contaminé à contre-courant provenant du filtre à lavage à contre-courant (17), et éliminer des matières solides, par exemple des copeaux, à partir du liquide de nettoyage contaminé, et un séparateur d'huile (21) conçu pour recevoir le liquide de nettoyage contaminé et éliminer l'huile du liquide de nettoyage contaminé, le séparateur d'huile (21) étant relié fluidiquement au second filtre (18) et conçu pour recevoir le liquide de nettoyage contaminé directement en provenance du second filtre (18). L'agencement du séparateur d'huile (21) suivant directement le second filtre améliore l'efficacité de filtration du système en réduisant les distances de trajet d'écoulement du liquide de nettoyage contaminé.
