Embodiment Construction

[0028] With reference to a filter device 1 schematically shown for industrial cleaning equipment figure 1, an industrial process for cleaning machined workpieces is first described. The workpiece is, for example, a motor or transmission component, such as a cylinder block, and is machined, for example, by drilling, milling, grinding or turning. Machining may require the use of lubricants, chip removers, rust inhibitors and coolants. Therefore, residues of these liquids and any chips or burrs left on the workpiece must be removed from the part after machining. For this purpose, the workpieces are subjected to a cleaning operation in a cleaning receptacle 11 containing a basin of cleaning liquid. Workpieces can be moved by conveyors or industrial robots (see image 3 ) to the cleaning container 11. A cleaning fluid, which may be water or an aqueous cleaning fluid using water as a solvent, is sprayed onto the workpiece through a plurality of nozzles 12 . Cleaning liquid is s...

Abstract

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 thecontaminated cleaning liquid.

Description

technical field [0001] The present invention relates generally to the field of industrial cleaning of machined workpieces, and more particularly to methods and industrial equipment for removing waste from cleaning liquids for subsequent cleaning of machined workpieces. Background technique [0002] The process of machining metal workpieces to produce finished components, such as engines and transmissions, such as cylinder heads, cylinder blocks, transmission housings, etc., requires the use of some kind of cutting tool to remove material from the workpiece to achieve the desired shape of the finished component. Machining operations may include drilling, milling, grinding or turning. After these machining operations, the workpiece is left with burrs, which are raised edges or small pieces of material that remain attached to the workpiece. These burrs must be removed along with swarf and other particulate matter from the machining process. Since the machining process may als...
