Abstract
A filter for solns. from washing operations or machine tool cooling, incorporates a band moving through a filter zone and fed from above by the soln. and has a channel under the edge of the band to receive any unfiltered overflow, an outlet chamber through which the filtered liq. passes, and has one wall which is a removable filter panel. If the band is ruptured, this panel acts as the main filter. The chamber also contains a float operated switch which interrupts the flow of soln. when the residues build up in the chamber. The filter band is an endless band carried on chains and several scraper blades are provided to remove the impurities, into the filter vessel, and to move them towards an outlet. Alternatively, the filter may operate intermittently, and the feed may enter through a chamber, the edges of which are hollow and flexible, so that they make a fluid tight joint with the band, and the soln. may be charged under forced circulation. The filter is more efficient, and more accurate than existing fillers, because it eliminates the risk of feed liq. and filtrate being mixed, for example by the filter band becoming perforated or the feed overflowing at the edges.
