Abstract

956,311. Filters. WILLIAM FRANKLIN & SON Ltd. Jan. 14, 1963 [Jan. 26, 1962], No. 3171/62. Heading B1D. Solid residue is detached from a filter element by vibrations generated by a device which is actuated by a manometric device sensitive to increase in pressure difference across the filter element caused by the accretion of solid thereon. The vibration generator may act on the filter element itself, or a vibratable support for the element or on a body of liquid in which the element is immersed. The vibrations may be supersonic, sonic or of low frequency. In one embodiment, Fig. I, a conical bag filter of woven nylon 10 is immersed in container 11 provided with inlet 12 and outlet 13 for liquid to be filtered, and with sump 14 having drain outlet 15 normally closed by valve 16. Filter element 10 is secured to hollow body 17 having rigid outlet pipe 18 connected by flexible tube 19 to outlet 13. Hollow body 17 is carried by rod 21 connected to vibration generator 20. This generator comprises (Fig. 3) rigid contact arms 27, 28 mounted on blocks 29, 30, electromagnet 24 and armature 23. Electrical supply lines 25, 26 are connected to manometric device 31, Fig. 2. This comprises aneroid chambers 32, 33 separated by impervious, electricallyconducting plate 34. Chamber 32 communicates via 35 with outlet 13, and chamber 33 communicates via 36 with inlet 12. When the pressure difference in chambers 32, 33 (a function of pressure drop across the filter) is increased, contact is made between plate 34 and contacts 37, 38 causing vibrator 20 to operate. The solid detached from the element gravitates to sump 14 provided with float 40. When a predetermined level of sludge is reached, float 40 causes switch 43 to close, and energize solenoid 44, causing armature 45 to tilt beam 46 about a pivot 47 and raise valve 16. The valve closes when switch 43 opens due to the drop of the float. In a further embodiment, Fig. 5, vibrator 20 carries a rod 21a bearing a perforated plate 48 which sets up vibrations in the liquid surrounding the filter element.
