SEPARATOR Filed April 1, 1931 Patented Feb. 14, 1933 PATENT OFFICE WILHELM LINNMANN, OF ESSEN, GERMANY snramron Application filed April 1, 1931, Serial No. 526,988, and in Germany January 11, 1980.
In automatically operating float-controlled separators for light liquids ordinarily a suction effect is ,being exerted on the float in case large quantities of water pass through the separator. This suction effect which in general willcause intermittent motion of the float may at times assume such an intensity that the float will be pressed upon the aperture which serves for the passage of the liquid through the separator with the result of premature closing of the latter and in consequence thereof flooding of the bottom with water.
According to my invention I provide a special or additional closing member which is adapted to reduce the effective cross-section or width of passage of the separator, said special or additional closing member being operatively connected with the main closing member or float to permit, to a certain extent, displacement of the former member with respect to the latter. The additional closing member Will thus still remain in closing condition subsequent to lifting the main closing member from its seat and move not before said main closing member has been lifted to an extent that all danger of the aforementioned suction effect will be avoided. The additional closing member which according to my invention serves for reduc ing the width of passage of the separator may be arranged and constructed in various ways. Preferably, for the purpose of my invention the additional closing member is constructed in the form of a plate positioned underneath the main closing member proper of the separator, said additional closing member or plate resting in closed condition of the separator on ribs provided for this purpose upon the discharge pipe. However, said additional closing member or plate may also consist of a foraminated plate or solely of a body which is immersed into the orifice A of the discharge pipe. The construction of my new separator is connected with the advantage that in the first place the aforementioned suction effect will be successfully pre- Vented, and that in the second place a sign r of warning will be iven to the owner of the plant, this sign of warning consisting in the fact that the stored up water flows over as soon as the quantity of liquid passing through the plant becomes excessive as compared with v the size of the separator, or in case the separator is in a condition requiring cleaning.
In spite of this, however, there will be a discharge of the water flowing over as the additional closing member which is mounted displaceably on the float solely reduces the effective width of passage of the discharge pipe. 6
Further advantages of my present construction consist therein that after complete lifting of the main closing member the full width of passage'ot the discharge pipe required for a free discharge of water will be cleared and closing members in position midway between closing and opening, Fig. 3 a similar detail vlew showing the closing members 1n closed condition, and Fig. 4 a further detailview of a modified form of the additional closing member.
Referring now more particularly to the drawing, the upwardly directed end of the discharge pipe (1 may be closed up by a main closing member or plate 6 which is connected with a float c positioned outside of the immersion pipe (Z within thespace e in which bcnzole may collect ontop of the waste-water. From the main closing member I; there is suspended a second or additional closing member f by means of a bolt 9 passing through slots 72, in said additional closing member f. Upon downward motion of the float. at first the plate f or additional closing member which is provided at its rim with apertures or passages i will be placed upon the ring-shaped seat 7 of the discharge pipe a, while'the main closing. member I) will still be positioned at some height above said discharge pipe. This position of the main and the additional closing member is shown in F ig..2. Unly upon further downward mo tion of the float, the main closing member or plate bwill come in contact with the ringshaped seat is as shown in Fig. 3 to close the passage through the separator. Thus, during lifting of the main closing member I) at first the additional closing member or plate f remains in position on the seat is and discharge of liquid from the separator can takeplace solely through the slots 71 in said plate. In this manner any suction effeet will be prevented from being exerted on the main closing member I) as long as it is positioned in proximity to the discharge orifice. Up'on'contin ued lifting motion of the float which will cause themain closing member 12 to be lifted out of zone of danger,
the additional closing member or plate f will now likewise be'moved, thus clearing the entire cross-sectionofithe discharge pipe (1.
According to Fig. 4 which shows a modified constructioh 0t my new separator, the additional closin member or plate fis of closed conformation at its periphery. Duringdownward' motion the plate f will come inccontact with the projections p which are provided on thering-shaped seat is at certain distances from each other to permit discharge of water through the passagesprovided intermediate s id .projections. The projections p are. prop erly spaced and positioned at a height permitting to obtain lee-1 tween .said prdjections a free clear cross-section in contacting condition of the plate and the projections which is smaller than the clear width of passage of the discharge pipe a. The plate 7 is mounted displaceably on a rod 7* providedwith a stop g, said rod being fastened to the float s.
