Abstract
1,044,082. Filters. J. MULLER. Jan. 27, 1964 [March 4, 1963], No. 3393/64. Heading B1D. A filter composing filtering columns 1 and 2 each composed of a stack of rings provided on one or both faces with grooves through which the fluid passes is cleaned by a piston and a valve device acting under fluid pressure which forces fluid through the columns inthe direction opposite to that of normal flow. In the embodiment shown in Fig. 1 fluid to be filtered enters through passage 111 and during normal operation passes through entry 112, through filter columns 1 and 2, into space 99 and out through passage 100, bellows 119 maintaining fluid pressure in space 99. Fluid also passes past needle valve 21 into cylinder 101 to act upon piston 103 which moves downwardly under the pressure. There is lost motion in the coupling between rod 107 and the piston rod 109 but when the piston rod abuts a clevis 11 it moves a link 12 downwardly compressing spring 18 in the process. Unfiltered fluid in space 110 is displaced via chamber 115 and pipes 20 and 117 back to the supply tank. When the piston has moved beyond the point of alignment with link 106 the spring 18 acts to move the link 106 upwardly and so move the two valves 104 and 105. Consequently fluid passes through entry 113 into space 110 and acts a piston to force it upwards so forcing fluid past non return valve 120 and opening 123 into space 99 from where some fluid passes through columns 1 and 2 in direction opposite to that of normal flow. Residue is forced into chamber 114 and thence into a collecting vessel through pipe 116. The valves change position. When piston reaches the top of cylinder. The poppet valve mechanism may be replaced by a rotary plug valve. In the embodiment of Fig. 8 (not shown) are part 148 of the cylinder containing the piston is rotatable and incorporates a distributor with an opening 149 arranged to register successively with the openings in the columns 50 cleaning the columns one at a time without interrupting the filtering operation. A heated fluid may be passed between the walls 97 and 122 of the casing to reduce viscosity. The collecting vessel may be of the pressure type or gravity type, illustrated in Figs.9 and 10, (not shown).
