Abstract

292,644. Brinjes & Goodwin, Ltd., Stewart, L., (Executrix of Stewart, R.), and Seaman, C. F. N. Feb. 24, 1927. Rotary filters. - In a vacuum filter of the type comprising a drum with peripheral chambers 13, the chambers 13 extend beyond the end plates 26, 27 of the drum and radial tubes 23, 24 are provided outside the end plates at either end of each chamber, the chambers being thus connected to two central valve members 18, 22, one of which serves for the discharge of strong filtrate and the other for the discharge of weak filtrate or wash liquor. The drum 1, Fig. 1, rotates on a stationary shaft 2 the central part of which may be solid or hollow and provided with a central plug 3. The ends of the shaft are hollow and pass outward through the walls of the trough 28 to which the material under treatment is supplied, and they are connected to suction pipes 33, 34 respectively. An aperture 20 on the lower side of the shaft puts the chambers which are submerged in communication with the suction pipe 33 for the strong filtrate, and a similar aperture 21 at the other end connects the uppermost chambers with the suction pipe 34 for the weak filtrate. Fig. 3 shows an arrangement in which a conical sleeve 41, which can be adjusted longitudinally to take up wear, is interposed between the valve member 18 and the shaft 2. In the alternative arrangement shown in Fig. 5, the valve member 47 is formed as a boss on the end 26 of the drum, the central shaft is hollow only at the ends and has coned portions 52<1> with apertures 53 within the valve members.
