E. SOBEK DISCHARGE FUNNEL FOR SILOS Filed Nov. 22. 1926 Patented May 8, 1928. v
UNITED sTATEs EMANUEL SOBEK, OF VIENNA, AUSTRIA.
DISCHARGE FUNNEL FOR sILos.
Application .flled November 22, 1926, Serial No. 150,041, and in Austria November 28, 1925.
This invention relates to dischargefum. nels for silos and the like and has for. its
object to provide a means for emptying a silo'etc. horizontally or in horizontal layers. This object is attained by providing immovable guide plates within the discharge funnel of a silo etc. and by arranging them at an angle to one another so that they radiate at the point of entrance of the material. They extend downwardly almost to the discharge opening without obstructing it,
divide the material into separate streams,
and guide it uniformly and in unbroken layers towards the discharge opening so that it is discharged without causing clogging. Simultaneously, the guide plates serve for relieving the walls of the discharge funnel partly of the load of the column of material pressing down on them.
The invention is especially useful'for lime kilns as it has been found particularly serviceable in cutting off shafts air-tight when compressed air is used for operation.
One form of the invention is illustrated in the accompanying drawing, in which Figure 1 is the conical discharge funnel of a silo, and Fig. 2, a top view of same. I
The silo which is not shown may be of any desired section and like thedischarge funnel at, whose opening is considerably narrowed.
be constructed in the usual-way. The silo may be round (circular or elliptical) square or polygonal and the discharge funnel of the same shape. Within the dischargefunnel several guide plates 6 are arranged, though there should never be fewer than two. guide plates 6 extend from the point of entrance of the material at a where they radiate down to the flanged opening 0 without The obstructing it, and intersect each other. Owing to this arrangement material piled up within the shaft is carried partly by the Walls of the funnel a and partly b the guide plates I) which thus relieve the unnel by taking 11 a large part of the load.
In a silo tted with guide plates arranged according to this invention the material will not only drop down freely to the funnel entrance without clogging the latter, but the discharge funnel, unlike existing types, may taper much more and he therefore much shorter than at present. The discharge opening too can be made much narrower and the shutting device such as a slide etc. also.
Material discharged according to this invention remains horizontally arranged in layers within the silo, is divided by the guide plates 6 into separate streams which do not interfere with each other while going down, and leaves the discharge opening of the funnel a in perfect order, for the latter is totally unobstructed and cannot cause clogging. This regular, orderly, and unhampcred movement of the material and its layers 1s of utmost 1mportance for emptying 51105 properly and lnsuring perfect functioning of same. i
In testimony whereof, I have affixed my signature.
EMANUEL SOBEK.
