Abstract
714,620. Filters. FARBENFABRIKEN BAYER. Jan. 23, 1952 [Feb. 10, 1951], No. 1918/52. Class 46. [Also in Groups II and XXX] Liquid to be filtered is caused to flow along a surface which is substantially impermeable thereto and is provided with multiple upright filaments which retain in their interstices the material to be filtered out. In the embodiment of Fig. 1 liquid is supplied at 8 to an inclined and upwardly-moving portion of a conveyer belt 1 preferably of rubber having its outer surface provided with hairs or bristles 5. Filtrate runs down into a funnel 9 and solids enmeshed in the bristles are removed by vibration of a horizontal portion 10 of the belt, by electric hammers 11 over a vibrating discharge shoot 12. A thin rubber rim 6 is provided on each edge of the belt. In Fig. 3 liquid to be filtered is fed to a plate 15 and runs down a conical surface 14, mud being retained by bristles 13 thereon. Filtrate is collected in a gutter 16. When the bristles 13 are clogged the surface 14 is rotated by a motor 18 whereupon themud is thrown onto the walls of the casing 19 and runs down into a gutter 20. In Fig. 4 concave discs 22 having hairy filtering surfaces 21 are rotated so that liquid fed to them from apertures 26 in a feed pipe 23 is filtered by centrifugal action, filtrate being received in a gutter 29. For cleaning, the apparatus is inverted about bearings 32, 33 and the discs 22 are slowly rotated and simultaneously vibrated by cams 35 running on a toothed disc 36. Mud falls onto a conical surface 37 of the casing 27 whence it falls into a discharge funnel 38. In Fig. 4 the hairs or bristles are preferably arranged in concentric rings around the vertical axis. In Fig. 1 the bristles are attached to the belt by strips arranged transversely of the direction of travel of the belt.
