Abstract

23,867. Koolman, J. ten Doornkaat-. Nov. 1, 1911, [Convention date]. Filter-presses.-Grids for distributing and collecting the liquid in presses having a compressed fibrous filtering-medium are constructed with bars d forming channels substantially parallel with the circumference or sides of the grids, the bars being interrupted so as to give a vertical channel e, which is connected by channels i with supply and discharge channels a, b and vent channels c, so that liquid rising in the parallel channels expels air through the vent. The bars or ribs may be concentric or spiral, Fig. 1, or, in the case of quadrilateral elements, parallel to the sides as shown in Fig. 3. There may be ribs f in the channel e and apertures h, which allow communication between the opposite faces of the grid.
