Improvements relating to Centrifugal Apparatus for Treating Molten
Material, and to Means for Removing the said Material from such
Apparatus.
I, ORRIN BURTON PECK, of 162, 34th Street, Chicago, Illinois, United
States of America, Mining Engineer, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
The object of my invention is to provide a simple and economical means for
treating and removing the molten material, and also for removing the gas and steam
that may be formed; and the invention consists in the features and combinations
hereinafter described.
In the accompanying drawings,
Figure 1 is a vertical elevation, partly in section, of the centrifugal machine,
together with the apparatus for removing the material and the gas and steam;
Figure 2 is a plan view of the entire apparatus;
Figure 3 is a horizontal section on line 3 3 of Figure 1 drawn to an enlarged
scale, looking in the direction of the arrows; and
Figures 4, 5 and 6 are vertical sections illustrating modified forms of discharging
spouts also drawn to an enlarged scale.
Figure 7 is a detail plan view of a screen.
V is the receiving-vessel A, the curb surrounding the same; B, the shaft for
supporting and revolving the vessel; CC, journal-bearings, for supporting and
maintaining the vertical position of the shaft; D, the discharge pipe or passage;
E a centrifugal pump; F, a discharge-pipe leading off from the pump; GG,
rollers or crushers mounted in the discharge pipe and driven by means of a belt-
wheel G and cog-wheels ggg', a weighted lever intended to hold the rollers G G
in proper relative position to each other; H, an exhaust or suction fan connected
with the discharge-passage D by means of pipe h, and provided with a discharge-
pipe H; I, a suitable engine for supplying power to drive the pump and fan;
J, an engine for supplying power to drive the centrifugal machine; J', the driving
wheel thereof, and K the driving-belt.
The receiving-vessel, curb, shaft B, with its bearings, engine for driving the
centrifugal machine, are not herein described their construction being obvious from
an inspection of the drawings.
From a point, preferably near the bottom of the curb A, I lead off a suitable
discharge pipe or passage D and connect it with a centrifugal or other force-
pump E, by means of which the material which flows out of the curb is forced
through the pipe F to any place desired. Through imperfect or insufficient
cooling, comparatively large lumps of material are liable to be formed in the
machine and, passing down through the discharge-passage, will clog or interfere
with the action of the pump. To prevent this interference with the pump, I prefer
to provide rollers G G. These rollers are supported as shown in the discharge

page_text: passage, and are provided with cog-wheels which mesh together. The shaft of
one of these rollers is provided with a belt-wheel G', driven by any suitable source
of power, as the engine I. These rollers are constantly revolving, and should be
so placed in the discharge-pipe that the material coming through the machine is
forced to pass between them, and any lumps too large to pass between the rollers
will be crushed or reduced in size by their revolution. One of these rollers or
crushers G is supported in a movable bearing L, the object of this being to allow
a slight play to the rollers.
In Figure 4 I have illustrated a modification of this crushing device, wherein
the surfaces of the crushing-rollers are provided with corrugations.
In Figure 6 I have shown a modification wherein I have substituted for the
crushing-rollers G a movable crushing-jaw M, operated by a toggle-joint N, or
other suitable mechanism. In the modification shown in Figure 5, D¹ is the
suction pipe of the pump E, and D is the end of the discharge spout, preferably
somewhat contracted toward its lower end. At some point between the pump E
and the curb of the centrifugal machine I provide a screen O, made of such size
as to permit only of the passage of such material as is proper to pass through the
pump. The larger pieces which are rejected by the screen pass down and out of a
suitable opening in the pipe or passage D.
In the use of the centrifugal machine for the treatment of molten material
a large amount of gas and steam is formed, and to provide the means for carrying
off' such gas and steam I employ a suitable suction fan H, or other means connected
as shown in the drawings, with the discharge pipe or passage by means of the
pipe h. The fan, may however be connected directly to the curb of the machine
or any other suitable part of the apparatus.
In my applications of even date herewith I have set forth the process and some
of the features of construction disclosed but not claimed in the present application.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
First. The combination with a centrifugal machine for the treatment of molten-
material of an exhaust-fan for drawing off steam or smoke, and a pump for pumping
away material and water, substantially as described.
Second. The combination, with a centrifugal machine for the treatment of molten
material, of a force-pump for pumping away the water and material, a spout
connecting the machine and pump, and an exhaust fan communicating with the
pump, substantially as described.
Third. The combination, with a centrifugal machine for the treatment of molten
material, of a force pump for pumping away the water and material, a spout con-
necting the machine and pump, and means for crushing coarser material on its
passage from the machine to the pump, substantially as described.
Fourth. The combination with a centrifugal machine for treatment of molten
material, of a force-pump for pumping away the water and material, a spont
connecting the machine and pump, an exhaust-fan communicating with the spout,
and means for crushing coarser material on its passage from the machine to the
pump, substantially as described.
Fifth. The combination, with a centrifugal machine for the treatment of molten
material, of a force-pump for pumping away the water and material, a spout
connecting the machine and pump, an exhaust-fan communicating with the spout
and rollers in the spout for crushing coarser material, substantially a described.
