CONTAINER FOR THE DRY COOLING OF COKE.

Application filed May 4,

1 '0 all whomv it may concern:

Be it known that I, ARNOLD Monr'rnm, a citizen of Switzerland, residing at Ober \Vinterthur, Switzerland, Alte Romerstrasse 31, have invented certain new and useful Improvements in Containers for the Dry (ooling of Coke, of which the following is a specification.

For the dry cooling of glowing coke taken from coke ovens and similar apparatus it has already been proposed to place the coke in large containers through which cooling gases pass from the bottom to the top whilst the cooled contents are drawn off from below.

In cokecooling containers of this type the circumstance known in silo structures has shown itself, that the central part of the container charge descends very quickly to the discharge opening whilst the part at the sides remains back. This is unfavourable to regularity in working of the cooling system. In order to avoid this drawback, over the discharge opening, structures have been provided which act to a certain extent as a brake on the central part of the mass of coke, thus leading to a more uniform descent of the whole charge of the container and thereby to uniform cooling. In very large containers, such as are required in modern collieries, the further drawback makes itself evident, that the air or cooling gases introduced below in the neighbourhood of the discharge opening of the container no longer pass in a uniform stream through the con tents but try principally to make their way up the sides, that is especially at the places below which the cooling medium is introduced.

According to the present invention the cooling gases are also introduced into the inner part of the contents of the container, thereby leading to a satisfactory uniformity in the cooling process, by the above-mentioned structures being adapted for intro ducing the cooling medium. For this purpose passages are provided inside the structures and these passages are fitted with 1923. Serial No. 636,540.

numerous discharge openings. The mouths of these discharge openings are at the same time concealed under projecting nose-pieces, so that it is impossible for the coke to force its way into them. By properly spacing these openings, by properly dimensioning them. and also by giving the proper form to the structure intended for braking the central tiow of the coke, it is possible to get the mass of coke to pass through the container absolutely uniformly, and to cool it absolutely uniformly, even in containers of very large cross section.

One example of a construction according to this invention is shown in the drawings where Fig. 1 is a longitudinal section along the line ll in Fig. 2, and

Fig. 2 is a section along the line II-ll in Fig. 1.

The. coke container a is filled continuously with fresh hot coke from above, in the man? ner customary when charging blast furnaces, and is emptied at the bottom at b as required, continuously or at intervals. The cooling medium is introduced, on the one hand through the annular passage d and the openings (1 in connection with it,-and on the other hand through the passages f and the openings r] provided in the structure it serving for braking the flow of the cooled masses.

It can at once be seen from the drawing that in this manner a uniform penetration by the cooling air or cooling gases of the whole contents of the container is obtained, and this makes itself manifest in working by the uniformity of the cooling process and the uniformity of the temperature of the coke removed at the lower end.

I claim:

In a container for dry cooling of incandescent coke by means of gas forced through the charge of coke as it passes through the container, the combination of a bottom part consisting of a hopper provided with a discharging device and with openings therethrough adapted for conducting cooling gas into the outer portions of the space therein, channels in the checking member with a a checking member in said container adaptsource of gas. 1 ed to prevent the central portion of a body In testimony whereof I have afiixed my of coke therein from droppin faster than signature in presence of two witnesses.

the remaining part, said chec ing member ARNOLD MOETTELI. being provided with channels and openings Witnesses: for injecting gas into the central portion of WILLIAM H. MATHER,

the hopper, and means for connecting the AUGUST BRUGG.
