The invention relates to a device for covering the extinguishing vehicle by a coke cake guide tightly closing hood extending over the width of the extinguishing vehicle and one on the Coke cake guide can be connected, while the coke is being pushed out over the already loaded one Cover plate that pushes part of the extinguishing vehicle.

When printing out the cooked coke from a coke oven chamber, the coke via a guide device is brought into the fire-fighting vehicle, which is slowly moving while it is being pressed out Smoke gases and dust. In particular, the formation of smoke at the beginning and at the end of the Expressing process due to the mostly not completely cooked heads of the coke cake considerably. Added to this is the considerable amount that occurs when the coke cake free falls into the fire truck Dust formation. The dust and smoke formation is also caused by the admission of air to the glowing Coke, which is subjected to surface combustion, favors the high heat of the coke causes the dust and smoke to lift.

It is known a cover plate arranged on a special chassis and a coke guide and the hood covering the width of the extinguishing vehicle cooperate during the extinguishing process to let the glowing coke, covered by the hood, slide under the Cover plate comes to rest. The cover plate therefore remains during the drive of the extinguishing vehicle to Extinguishing tower connected to the fire fighting vehicle. With this known device light appearances be avoided. This partially avoids the occurrence of smoke and dust. However, smoke and dust can still be present while the cover plate is being pushed over the fire engine from the open part of the Exit the extinguishing car.

It is also a safety device on coke extinguishers known, in which a driving channel on both sides of the extinguishing vehicle in order to avoid Is provided with a cover in the event of an accident. This cover is provided by those traveling in the canal The fire fighting vehicle moved and wound up at the end of the sewer.

The invention now consists in the fact that the fire truck at the empty end with a also at the Coke cake guide to be attached, the fire truck closing auxiliary cover is provided.

In this way, access to the coke is also a device for covering the extinguishing vehicle

avoided while sliding the cover plate. Furthermore, the during coke expression the resulting smoke gases and dust are kept or kept in the closed transfer system. for the most part withdrawn into the oven chamber during the squeezing process, so that a nuisance to the Environment is practically avoided.

According to a further feature of the invention, the auxiliary cover consists of elastic sheet steel and is in a known manner on a drum mounted at the associated end of the extinguishing vehicle windable.

The extinguishing car is covered before the start of the pressing process by means of the Auxiliary cover, which is coupled to the hood, whereupon also after coupling the cover the glowing coke of the extinguishing car making cover plate, the extinguishing car by slow Moving on while pushing out is pushed under the cover plate. It is in the same Measure the auxiliary cover made of elastic sheet steel at the other end of the extinguishing vehicle wound on the drum or, if an auxiliary collapsible cover is used, by folding it up pushed into each other.

The invention is illustrated in the drawing, for example, wherein FIGS. 1 to 3 show the fire truck show schematically in the various positions of the extinguishing process.

With a fire truck is referred to, which moves by means of a locomotive 9 along the open battery will. The fire truck 8 is used to accommodate the

glowing coke squeezed out of the furnace chamber and for transporting it under a coke quenching tower, not shown, to quench the coke. Connected to a coke cake guide carriage, also not shown, is a hood 10, which is configured at right angles in cross section and has an approximately quarter-circle configuration in longitudinal section. As can be seen from the dash-dotted lines, the hood 10 can be swiveled up in order to enable the locomotive 9 to pass through with respect to the raised driver's cab. The swiveling of the hood 10 can be carried out in any way, preferably hydraulic lifting devices are used for this purpose, which are operated by remote control or also automatically. The extinguishing carriage 8 is covered with an auxiliary cover 23, which can consist of a thin steel sheet, before the coke pressure begins. The elastic steel sheet is wound on a roller 24 that can rotate about a shaft and is guided by rollers 37 which are arranged on the arms of the extinguishing vehicle 8. The winding of the auxiliary elastic cover 23 is preferably spring-like so that the steel sheet has a tendency to wind itself. The elastic cover 23 is initially used to close off the upper part of the extinguishing vehicle over its entire length before a squeezing process. During the pressing out process, however, the elastic cover is removed when the extinguishing vehicle is moved, a cover plate 22 being brought over the extinguishing vehicle filled with glowing coke at the same time. An auxiliary carriage 27, which is coupled to the extinguishing carriage 8, is used to guide and support the cover 22. The cover plate 22 has a length such that it can completely cover the fire truck 8. In the same way, the auxiliary cover 23 also has a length that covers the entire extinguishing vehicle. Both covers are removed while the coke is being quenched in the fire fighting vehicle and while the fire fighting vehicle is being unloaded from the latter. Before the coke extraction process begins, the coke cake guide carriage is pushed up to the oven chamber 21 to be emptied after the doors have been removed from the oven chamber. The locomotive 9 now pulls in the direction of the arrow ^ 4 (Fig. 1) the extinguishing car 8 and the auxiliary car 27 coupled with it to the furnace to be pushed. The hood 10 is now pivoted downwards so that the auxiliary cover 23 comes into engagement with the hood 10. The extinguishing vehicle is driven further in the direction of arrow Λ, whereby the auxiliary cover 23 unwinds from the drum 24 and covers the extinguishing vehicle 8, as can be seen from FIG. The hood 10 is now in the initial position of the filling of the extinguishing carriage 8 and is also coupled to the cover 22, whereupon the squeezing process can begin. The locomotive pushes the extinguishing car 8 with its auxiliary car in the direction of arrow B, at a speed corresponding to the expression of the coke from the coking chamber, so that the coke is distributed in an even layer over the entire length of the extinguishing car. As a result of the mutual connections of the xo hood 10 with the covers 22, 23, the entire fire truck is completely covered. When the extinguishing carriage moves, it is pushed under the cover plate 22 in the course of the filling process of the extinguishing carriage, the auxiliary cover 23 winding up on the drum 24. In this way, the access of air to the glowing coke and the escape of dust and gases are essentially prevented; these can only get into the furnace chamber through the hood 10 and the coke cake guide. When the position shown in Fig. 3 is reached, the squeezing process is ended. The hood 10 is swiveled up and thus freed from the coupling with the covers 22, 23, whereupon the extinguishing car is driven to the coke extinguishing tower. The covers 22, 23 can form a complete gas-tight seal. However, it may also be necessary to mount one or more fuel gas valves in the cover plate 22 in order to discharge fuel gas that occurs in excess pressure from the extinguishing vehicle and burn it while the extinguishing vehicle is being moved to the extinguishing tower. Patent claims: 1. Device for covering the extinguishing car through a coke cake guide tightly final, extending over the width of the extinguishing car hood and one to the Coke cake guide can be connected while the coke is being squeezed out over the already loaded part of the extinguishing vehicle sliding cover plate, characterized in that the extinguishing vehicle (8) at the empty end with one that is also to be attached to the coke cake guide and closes the fire truck Auxiliary cover (23) is provided. 2. Apparatus according to claim 1, characterized in that the auxiliary cover (23) from consists of elastic sheet steel and in a manner known per se on one at the associated end of the Extinguishing carriage (8) mounted drum (24) can be wound.
