The present invention relates to a method of and an ; arrangement for filling coal in oven chambers of a coke oven battery by a telescopable filling pipe which i6 formed on a filling car and is lowerable with its lower end to a filling -~ opening frame of the filling opening of the coke oven battery.
~ The charging of the coke chambers of a coke oven , , battery is performed through a filling opening arranged in the oven cover, which is closed during the coking process by a so-called filling opening cover. Duriny filling of the oven chambers the cover is removed by a cover lifting device, so that the coal supply can be performed from the filling car ~' through the lowered filling pipe. The filling pipe forms a tight closure with the filling opening frame, which prevents escape of gas drawn with the incoming coal and produced during r the utilized coking process. This gas can be aspirated many , times through the filling pipe and supplied to cleaning devices and/or to a collecting main of the coke oven battery.
Since this gas contains dust, bituminous components and other impurities to a great exten~, the residues of these impurities , '~

`~ Accordingly, it is an object of the present invention to provide a method of and an arrangement for filling coal in oven chambers of a coke oven battery, which avoids the disadvantages of the prior art.
In ~eeping with these ob~ects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a method of the above mentioned general type in which the lower end o~ the filliny n pipe i8 closed at the beginning of the lifting and the closure is maintained until the beginning of the next filling step.
s In addition, the emission safety can be further increased when in accordance with the present invention at the end of the filling proGess, before the lifting of the filling pipe, the gas which remains in the filling pipe is aspirated.
The aspiration can be performed by the negative pressure applied in the oven chamber through a drawing piping mounted on the ~illing pipe, and the begin~ing of the aspiration step is activated by a control system. The drawing pipe can also ., aspirate the gases which are produced during combustion of the residues located in the fllling pipe and during lifting of the filling pipe are compressed due to closures of the filling pipe. Thereby emission escape at the sealing elements of the sealing pipe due to the pressure increase is prevented.

T'nereby it i5 guaranteed that during the lifting of the filling pipe a sealing of the filling pipe is performed immediately, after the aspiration of the filling . gas has been interrupted.
Closures of any type are sultable as closing elements for the filling pipe. In particular, a closure can .
be ~ormed as a cover which i6 turnable in or on the outlet opening o~ the filling pipe, and can be displaced, lifted or drawn. Also, the same functions can be performed by a slider arranged in the outlet opening. The closing elements can be naturally provided with a suitable heat resistant coating.

2l~6~sl9 -~ In an arrangement in accordance with the first embodiment shown in FIG. 1 a filling pipe 1 is formed as an integral element and surrounds an outer pipe 2 of a filling car which is not shown in the drawings. It is to be understood that also it is possible such an embodiment in which the filling pipe is composed of several pipe pieces which are telescopable relative to one another. The filling pipe 1 and the outlet pipe 2 are surrounded by a ~lexible seal 3 which is expanded downwardl~ during lowering of the filling pipe 1. The ~illing pipe 1 is connected through a supporting ring 4 and link rods 5 with a lifting beam 6. The upward and downward movements of the li~ting beam 6 which lift and lower the filling pipe 1 is performed by a not shown electrically or hydraulically operated lifting device.
In accordance with the present invention the filling pipe is provided at its lower end with a cover 7 which serves as a closing element. The cover 7 is suspended on a `~3 supporting ring 9 through hinge rods 8, and the supporting ring 9 is mounted on the turning arm lO. The turning arm ?
and the supporting ring 9 are connected with a hydraulic cylinder-piston units 12 through the rods 11. The hydraulic cylinder-piston units 12 is mounted on the lifting beam 6 and operates for providing the lifting and lowering movement of the cover 7. As can be seen ~rom the plan view of FIG. 2, the ~,~

, ' ~ ', '. ' '.'b' ' 2126~59 1 turning arm lo is additionally connected with a hydraulic , cylinder-piston units 13 which provides outward and inward ¦ turning of the cover 7. The reference numerals of FIG. 2 ,,,,l~Z correspond to the reference numerals of FlG. 1.
The arrangement in accordance with the present ;~! invention operates in the following manner:
~3 ''''r, In the initial position when tha filling pipe 1 is ~1 ~?~i lifted and closed by the cover 7, the hydraulic cylinder-piston units 12 and 13 are retracted. When by a control signal the lowering step o~ the filling pipe 1 is actuated, , i,, first the hydraulic cylinder-piston unit 12 is extended and the cover 7 is removed from the Pilling pipe 1 and lowered ~,, downwardly. Then the hydraulic cylinder-piston unit 13 is extended, and the lateral turning movement of the cover is performed in correspondence with the dash-dot line in FIG. 2.
When the hydraulic cylinder-piston unit 13 is completely extended and the cover 7 is completely turned, the downward .., i movZsment of the filling pipe starts. Simultaneously, the ,:, ~Z hydraulic cylinder-piston unit 12 i8 retracted and the turned-", 20 out cover 17 is lifted. Since the cover 17 is connected ''''~`"d through the hydraulic cylinder-piston unit 12 with the lifting Z beam 6, a constant great safety distance between the oven top 16 and the turned-out cover 17 is always provided with the ~, filling pipe 1 completely lowered on the filling opening 15 Z~ 25 and with the completely retracted hydraulic cylinder-piston ~' Z
.
'?, ~,, 1 unit 12. In this manner, height variations of the oven top 16 and the filling opening 15 caused by constructing the arranqement are compensated.
Immediately after finishing the filling process, the lifting of the filling pipe 1 is per~ormed in response to a control signal and simultaneously the extension of the hydraulic cylinder-piston unit 12 is executed. When it reaches its end position, the hydraulic cylinder-piston unit 13 is retracted and the cover 7 is turned under the filling il~
-~ lo pipe 1. A stopper 14 which is connected with the rod 11 guarantees that the cylinder-piston unit 12 is then completely extended when the filling pipe 1 is lifted so that an exactly definite distance between the cover 7 and the filling pipe 1 is provided. This position of the stopper 14 is shown in FIGS. 1 and 3 with a dash-dot line. The switching guarantees that at the beginning o~ the turning always a sufficient safety distance between the cover 7, the filling pipe 1 and the oven top 16 is provided and thereby the earliest possible turning-in of the cover 7 is per~ormed. A~ter the hydraulic cylinder-piston unit 13 has been completely xetracted, the hydraulic cylinder-piston unit 12 is retracted and the cover 17 is pressed under the outlet opening of the filling pipe 1 which is thereby closed in a gas-tight manner. The filling pipe 1 can then be retracted to its initial position.
