Improvements in the Method of Quenching, Transporting, Sifting
and Loading Coke, and Apparatus used therein.
I, JOSEF MULLER, Engineer, of Essen on the Ruhr (Zeche Mathias), Germany,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
-
My invention relates to a new method and the apparatus used therein for
treating coke as it comes from the ovens in a hot state and it has for its object
to at once quench the fiery coke in water, raise it out of the water and allow it
to dry and discharge it upon a sieve or grate to free it from ashes, and finally load
it into waggons or stow it in boats all in one continuous operation automatically
and mechanically without any hand labour whatever.
The apparatus realising all the operations named consists in the main of a
tank filled with water, into which is sunk a carrier that carries the coke plunged
into the water and upon the carrier out of it and then transports it a certain dis-
tance out of the water so that it can dry and discharges it then upon a sieve or
grate forming part of the apparatus, in order to get freed of ashes adhering to it,
and from which it finally is loaded into waggons or other vehicles for further
transport.
The accompanying drawing shows the new apparatus for carrying out my
process of working.
Fig. 1 shows a vertical longitudinal section;
Fig. 2 is a plan of Fig. 1;
Fig. 3 is a vertical section of the left side of the apparatus in an enlarged scale;
Fig. 4 is a cross section along line II-II of Fig. 3;
Fig. 5 is a cross section of Fig. 1 along line I-I;
Fig. 6 is an arrangement showing the carrier placed at right angle of the
ovens;
Fig. 7 is a cross section of this arrangement looking towards the left.
In front of the coke oven or of a series of ovens A, as shown by the arrange-
ment Fig. 1 to 5, there is at the discharge side of the ovens a tank B, which is
filled with water up to its upper edge. At the left end a bridge C is built over
the tank, leaving the space below it free. At the opposite end the tank has a
sloping border D. Into this tank is placed the carrier and transporting appa-
ratus proper, so that it reaches underneath the bridge C at the left side, it con-
sists of a strong frame F on wheels E which run on transvers rails E¹ so that the
whole apparatus can be shifted like a waggon cross ways in the tank. Strong
side beams of plates and U bars form the frame of the waggon, crossbars and
stays serve to strengthen it laterally. The part G of this waggon or frame near
the oven is built horizontal (Fig. 1) and is sunk totally into the water; the other
part Grises gradually, so that the end H is quite out of the water and so high
that there is sufficient room below it for a sieve or grate S, which may be built in
one with the carrier as shown, or it may form a separate part of the apparatus.
This sieve or grate may be made with movable bars or they may be arranged as
.

page_text: fixtures. When arranged separately from the transporter frame it may run
accross the whole width of the tank.
At both ends of the frame are shafts K and L carried in suitable bearings and
having drums K¹ and L¹ respectively keyed thereon, round which the carrier
indicated
chain M is laid. The shaft K is set in motion by the gear wheels N,
by dotted lines in Fig. 1 and it thus causes the rotation of the carrier chain.
The carrier band consists of two chains P one at the right edge and the other
at its left edge; by bolts Q they are connected laterally and these bolts form at
the same time the axles for the carrier wheels R upon which the chains are
carried forwards.
Plates S rivetted or bolted upon the chains and reaching from one side to the
other end each, of exactly the width of the pitch of the chain links form together
a continuous platform; every alternate plate may be provided with a transporting
angle T.
As will be seen from Fig. 1 the carrier chain reaches below the bridge C and
for its first half of the length it is submerged in the water.
The cokes coming from the furnace in a hot glowing state are pushed directly
upon the carrier chain into the tank, when they are quenched and slowly carried
forwards; at about half length (G) they are raised out of the water, and upon the
rising part G of the carrier chain the water can drop off and the cokes are
dryed; the heat contained in them supporting the drying process, so that they
arrive almost quite dry at the end, where they are thrown automatically upon the
grate J to get freed from ashes and slope down into the waggons U.
The transporting band or table moves between two inclined side planks V,
which are so fixed to the waggon frame F that the plates S pass below the lower
edge of the planks and that the latter project a little outside of the edges of the
planks so that no coke can fall out. The rails or guides for the chain wheels R
are formed by the U irons F, making part of the waggon frame, its upper hori-
zontal stay carrying the upper chain; the lower horizontal stay carrying the
lower or returning chain.
When a coking chamber has been emptied and the cokes from it have been
quenched, transported and loaded, the whole apparatus is shifted sideways before
an other chamber, ready for discharge; the apparatus being rolled sideways by
means of the wheels E upon the rails E¹.
The power for driving the carrier chain may be taken from any suitable
source.
The shaft of the gear wheel ( may run right accross the whole width and the
wheel is then shifted crossways upon it together with the apparatus, or a port-
able engine, which is also moved sideways, when required, may give out the power,
or preferably an electromotor may drive the machine as may be convenient. This
is of no particular influence upon the design and working of the apparatus and
depends on local arrangements and convenience.
The arrangement shown in Figs. 6 and 7 differs from the one described above
only in the manner of placing it before the coke ovens and in minor constructive
details; in every other respect it is equal to the preceding one, especially in the
manner of working.
As will be seen from Fig. 6 the carrier is placed lengthways along the coke-
ovens A¹; that is to say parallel to their front, instead of being placed in the
same direction as the chambers of the ovens. The tank B finds its place again
just in front of the ovens, but it can be made narrower in the direction of the
chambers, whilst its length extends beyond the exterior side wall of the ovens at
one side, either at the left or at the right side; in Figure 6 it is shown at the
right side. The border near the ovens is again partly covered by the arched
bridge C¹ and the sloping border D¹ in this case is at the right end of the tank.
As will be seen and as stated above, the carrier with its transporting chain lies
parallel to the face of the oven front, its edge A near the oven reaching below

page_text: the bridge is made narrower than the edge A' at the other side, so that cokes
pulled or thrust out of the oven can fall conveniently upon the carrier, but are
prevented from being thrown down at the other side. Rails e¹, e¹ are laid at the
bottom of the tank upon which the carrier can be rolled towards the right or
left accross the ovens, but in this case this transport is in the direction of the
carrier itself. The wheels e of the carrier in this case of course are arranged
accordingly.
In order to be able to carry the cokes coming from the chambers near the
right side wall the tank may be prolongated at this side as indicated by the
dotted line d so that the whole apparatus together with the grate J¹ can be
shifted towards this side.
In every other respect and all the other parts of the apparatus are the same as
those shown and described with Figures 1-5.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1.) The method of quenching, transporting, drying, sifting and loading cokes
coming directly from the coking oven in one continuous operation without
manual labour consisting in that, that the red hot coke pushed out of the furnace
is thrown in a tank filled with water, taken up by an endless transporting chain
and carried a certain distance in said tank then raised out of it in an incline
above and out of the water to allow the adhering water to drop off, whereupon it
is thrown upon a sieve or a grate to get freed from ashes while sliding down
automatically said grate into a waggon placed underneath the same, the whole
as set forth and for the purpose specified.
2.) In a mechanical apparatus for quenching, transporting, drying, sifting and
loading coke in one continuous operation directly as it comes from the coking
oven, the combination with a water tank B of an endless chain carrier G Gi
partly submerged in the water in the tank, partly rising out of it, a sieve or
grate, J below the raised end of the carrier freeing the quenched and dried coke
from ashes and allowing it to slide down thereon into a waggon U or other
vehicle placed below it.
3.) In a mechanical apparatus for quenching, transporting, drying, sifting and
loading coke in one continuous operation directly as it comes from the coking
oven, in combination with frames F, carried by wheels E or e on rails El or e',
shafts K and L having drums K¹ and L' respectively keyed thereon; endless
chains M placed round said drums, the chains being connected by plates S to
form a continuous movable platform; transporting angles T on said plates; side
plates serving as guards to prevent coke from being thrown sidewards out of
the carrier chain, the whole as illustrated and for the purpose set forth.
Dated this 28th day of April 1898.
