INCLINED WHARF FOR COKE BATTERIES Filed June 2, 1938 nl QA: ft @www3/Wg@ Patented June `11, 1940 f UNITED STATES PATENT 2,204,022v` i, INCLINED `vvnAltF Fonoonn ovnN c BATTERIES L i KarlxMack, Essen, Germany, assigner, by mesn assignments, to` Kappers Company, Pittsburgh, Pa., a corporation of Delaware y Application June `2, 193s, seriarNo. 211,43

, In Germany June 5, 193'7v s claims. (c1. 19a- 52)` `The present invention relates to inclined wharfs or the like provided for chamber or retort lovenubatteries for the production of gas and coke,` in which the coke produced in said ovens `which the Coke from the coking chamber is,`

pushed. The car loaded with coke is then driven fto the quenching tower, where wateris sprayed over the glowngcoke. `I heicluenched cokeis iinally discharged from the quenching car onto `an inclined `wharf where the coke remains for a i lgiven time `until the excessive quenching water has drained-off and the coke has steamed-out.

In `order to ipreventithe coke from sliding-oli `the inclined discharge wharf, `gate-like holders are provided atthe lower edge `of the wharf, said gates may be liftedupwards forthe removalof the coke from the inclined wharf.

For the transporting thel coke from the `inn-clined coke wharf to storage or to a loadingstation, `a belt conveyor is often used, for instance i a belt conveyor `made of india-rubber or another suitable material. "This conveyor is so arranged that it extends along the lower edge of the inclined wharf so that the coke may bedischarged -from all `points of the wharf onto the"belt conveyor after lifting the respective finger gates.

p plates alongtheconveyor has the disadvantageA that coke pieces easily stick between the guiding walls and-the edge of the conveyor belt, thus tearing olic the india rubber cover of the belt.

In order to avoid such destruction, it has been i tried to have the conveyor belt run as closely as possible along the guiding walls and to support `the belt by a multitude of rollers which control the, direction of movement of the belt and its exact position relatively to the guiding walls.

a multitude of adjustable guide plates extending plates.

The rollers are mainly intended to' prevent a sagging of thebelt, as it may easily happen that, with the sagging ci the belt, intervening spaces `between the belt conveyor and the adjacent guiding wall will be formed, into which coke ,.5

pieces may penetrate,,andaccumulate.` By the arrangement of a greater numberof supporting rollers, the conveyor cost isconsiderably increased quite apart from the fact that frequent damages to the belt willoccur notwithstanding the greater number of'supporting rollers.

Another disadvantage of the hitherto known` arrangement of belt conveyors for coke wharfs `or the like Icons'ists in that the coke sliding away from thewhari takes a direction transverse to Vthe movement of the belt conveyor. As the coke pieces impinge upon the belt, the `direction of movement ofthe coke is practically deflected at a right angle. This deflection causes a considerable stress upon the conveyor cover and although the` conveyor` cover` is usually strengthn ened for the above reasons, for instance by increasing the `thicknessof the rubber layer, the wear and tear on the cover or surface layer of the india-rubber conveyor belts at coke wharfs, and in similar cases, is so considerable that the india-rubber belt hasto be replaced frequently.

Now, the main object of my present invention` is to provide such improvements whichwill eliminate the before mentioned diliculties of the conveyor belts` or vthe like at coke wharfs and other contrivances when similarly unfavorable conditions are prevailing and which has further advantageslasmay be seen from the followingdescription.

The principal `improvementaccording to my present invention is to arrange at the lower edge of the coke wharfs of coking plants, or gasworks, or similar contrivances rltted with belt conveyors,

, essentially inthe direction of the upper side of the wharf, said guide plates being situated above the conveyor belt, and being provided on their upper side, with adjustable projections which will deflect 'the coke sliding over `the said guide Another important feature of my invention isthat the inclined adjustable projections of the guide plates are bent similar to a ploughshare insuch a way `that the material pressing `againstthe said projections is not only directed laterally but at the same timeralso `a little downwardly during the course of its descent alter leaving the wharf so that `the material may preferably accumulate in the centre of the belt conveyor.

With the above and other objects and features of my present invention in, View, I will now describea preferred embodiment of my invention on the lines of the accompanying drawing, in which Figure 1 is a vertical section through a coke discharge Wharf constructed according `.to my invention. -f

Figure 2 is a view` from above of the guide faces of the guide plates.

On the drawing the coke oven battery, coke quenching car, etc. are omitted as such contriv ances are well-known to all those skilled in the art.

'Ihe upper side of the cokev discharge wharf, consisting of cast-iron plates or the like, has been marked I on the drawing. The-wharf itself is formed by a frame 2 which is designed so thatk Athe end of vthe wharf projects into a channel 3 through which runs a belt conveyor 4. The upper strand ofthe belt 4 isfheldby supporting rollers 5 and the lower vstrand by supporting rollers 6. As usual, the upper supporting rollers within the range ofthe coke wharf are constructed in suchr a-Way that the belt conveyor is bent like a trough.

On the discharge Wharf I, the material marked l, for instance,y coke, is held by the finger gates 8 which are fastened to the carrying levers I 5 in such a waythat they can be'lifted from wharf I.

the service alley I0 into the position lmarked in dotted lines at II.y

After lifting the finger gates 8, the coke, in freely Isliding off from the wharf at II comes first onto the `guide plates I2 which are substantially situatedv in the direction of the upper side of the The guide plate I 2 can be turned round a horizontal axis vand for this purpose they are supported'adjustably `by being pivoted at point i3' on suitable projections I4 of the wharf frame 2.' Preferably, these guide plates I2 are provided all along the whole length of the wharf I. It is, however, also possible to arrange 'the novel mechanism so that, instead of being arranged in xed relation to the wharf for rotation about the axis I3, the guide plates are carried movably and slewably on a track, so that a certain number of guide plates I2, possibly combined with one another into one unit, may be moved along Ythe wharf to the various points of the wharf where it happens that the coke is to be discharged.

On the upper side of the kguide plates I2, projections. or guide deflectors I5 are arranged in such a way that they extend slantingly in the direction of conveyance of the belt 4. Figure 2 of the drawing shows by arrow I6 the direction of conveyance of the belt conveyor 4. It can be seen from Figure 1 that the guide plates I2 and theI guide deflectors I5 extend over the belt conveyor 4. The guide deflectors I5 (see Figure 2) are bent at the top similar tol a ploughshare. Consequently, the walls of the guide deilectorsA I5 defiect the coke, while it is ksliding after'leaving the edge of the wharf I and impinging against the sides of the defiectors, not only laterally in the direction of conveyance of the belt but alsodown wards. In this way, a uniform accumulation of the material inthe centre of the india-rubber belt conveyor is obtained.

'I'he guide defiectors I5 have at their base,

openings Il vformed las oblong holes which are' penetrated by the fastening-screws for the guide deflectors. It is, therefore, possible to adjust the angular position of the guide deflectors I5 with respect to the guide plates so that the adjustment is in exact accordance with the nature and the sliding speed of the material. If the in `clined or angular position of the guide defiectors has to be altered considerably, the deectors are suitably connected movably about a point with the guide plate.

I have in the above described the present inven-` tion on the lines of ya preferred embodiment thereof, but my invention is not limited in all its aspects to the mode of carrying it out as den scribedv and shown, since the invention may be variously embodied Within the scope of the fol# lowing claims. Q
