Title: Liquid filtering apparatus
Inventor: SCHNEIDER JOHN RUSSELL
IPC: B01D25/127
Filed: 1969-07-22
Abstract: 1,247,398. Filtering apparatus, J. R. SCHNEIDER. 22 July, 1969 [31 July, 1968], No. 36690/69. Heading B1D. A filtering apparatus comprises a stack of horizontal plates 22 between which extend respective webs of filtering paper 26, which are normally clamped between adjacent pairs of plates (Fig. 2) to separate upper inlet chambers from lower filtrate chambers, but are periodically advanced to replace used paper, loaded with solid contaminents, by fresh paper from rolls 24. The upper faces of the plates are grooved at 60 to drain filtrate to outlets 62, and the inlets 54 and outlets 62 of the plates are connected by flexible hoses to respective upright manifolds 32, 34, which also serve as guides up which plates 22 are slidable. Inlets 64 enable drying air to be forced through the filter cake after filtering under pressure, and serve as air vents during filtering. Peripheral grooves 66 are connected to vacuum to ensure good sealing. The plates are linked together (Fig. 3, not shown), so that they move apart consecutively as electric motor 46, gears and screw 40 raise upper plate 38. The plate separating movement closes a switch (189) enabling a time switch (184) to start the paper-advancing movement. In Fig. 1 the webs 26 are advanced out of plates 22 and across a stack of slotted tables (90) of staggered lengths by transverse bars (100) which carry pins (98) extending during their forward motion through the webs 26 into the slots (96) in the tables but raised out of the webs during their reverse motion. Bars (100) extend between a pair of side members (102) (Fig. 6, not shown) and describe a rectangular motion as horizontal and vertical pneumatic cylinders 124, (126) are actuated by a four-way valve (152), which is actuated by a follower on the moving bar frame. Thus the webs 26 are advanced in a series of steps as long as the time switch is closed, and when it opens a circuit (Fig. 19) ensures that the bars (100) stop only when pins (98) are engaged with the webs, preventing dirty web being pulled back when plates 22 are closed. The apparatus as a whole is controlled by another timer. Pins (98) have springs to ensure disengagement from the webs when they are raised (Fig. 18, not shown). Figs. 15 to 17 (not shown) represent an alternative web-advancing system wherein the bars (100) are mounted on side members whose upper and lower ends are pivoted to an array of four endless chains driven by a common motor. The web-advancing section of the apparatus is mounted on casters for pivoting movement about a vertical axis adjacent the filtering section, thus enabling any misalignment of the webs to be corrected. Fig. 20 (not shown) illustrates how any deviation of one web 26 from its median path is detected by air jets directed on its edges and automatically actuates a valve and pneumatic ram to shift the web advancing section round and correct the deviation. Only one web is so monitored, as all webs are assumed parallel.
