Description

COOKING OVEN MACHINE WITH A DEVICE FOR COLLECTING AND REMOVING SADDLE COKE

The invention relates to a coke oven operating machine according to the preamble of claim 1.

Coke ovens consist of a plurality of disk-like coking chambers, which are arranged side by side in a long row. Following coking of coal, the coke is discharged from the furnace with a coke-blowing machine. The necessary opening and closing of the oven doors on the side of the coke ejecting machine is carried out automatically by the coke ejecting machine. The coke pushed out of the furnace by the coke-blowing machine is directed into a coke-fire vehicle by the cake guide integrated on a coke-transfer machine. The required opening and closing of the furnace doors on the side of Koksüberleitmaschine is automatically carried out by the Koksüberleitmaschine.

When opening the oven doors for the Ausdrückvorgang fall on both the side of Koksausdrückmaschine as well as on the side of Koksüberleitma- machine larger amounts of Schlabberkoks, which must be removed from the range of the respective master gear.

To catch Schlabberkoks Koksofenbedienungseinrichtungen are known in the prior art, wherein a coke bucket is disposed in a Auffangstellung below an oven door of the coking chamber near the master cast and wherein the coke bucket of the Auffangstellung to a basic position in the process of Koksofenbedienungsmaschine or in a Emptying position for emptying the collected Schlabberkokses can be transferred. When transferring the collecting position into the emptying position, the coke shovel is lifted from the ground-level region of the master conveyor and pivoted into a position required for the subsequent rear emptying.

From DE 6 750 015 U a device on coke oven systems for collecting Schlabberkoks is known, one provided on a Koksausstoßwagen and / or on a Kokskuchenführungswagen to the and / or provided on a Kokskuchenführungswagen provided on the chamber opening of a coking chamber and Schlabberkoks catching coke bucket is provided.

A disadvantage of the known coke oven operating devices of the type described above is that the pollutants caught in the coke bucket of the coke bucket are released into the area of the coke bucket as emissions which do not escape from the suction devices usually provided on the coke ejecting machine and / or the coke transfer machine be detected. In addition to dusts, these emissions include, in particular, vapor, gas or smoke emissions. The extinguishing of Schlabberkokses is basically possible with and without water. If the coke bucket is at least partially filled with water to extinguish captured slag coke, the water evaporates when hot slag coke is collected. Together with the vapor, in addition to particles, gaseous pollutants are discharged from the interior of the coke shovel into the surrounding area of the coke shovel.

A coke oven operating machine is known from DE 10 2005 046 543 A1, in which suction elements of a suction device are arranged on and / or in the coke bucket of a coke oven operating device in order to detect directly the emissions released in the area of the coke bucket, before the emissions are exceeded from the inside of the coke bucket into the environment can come. The suction elements are firmly connected to the side walls of the coke bucket. As a result, in the conventional coke oven operating machine, it is provided to connect the suction members directly to the coke bucket of the coke oven operating means provided for catching and removing slag coke, the coke bucket being moved and pivoted together with the suction members from a home position and a discharge position to a receiving position.

In the known Koksofenbedienungsmaschine of the aforementioned type with arranged directly on the coke bucket suction is disadvantageous that the assembly of coke bucket and suction has a comparatively high weight, which in the adjustment movement of the coke bucket between the basic position and the Auffangstellung to a increased burden of coke oven operation device leads. Moreover, it can come when collecting Schlabberkoks clogging of the suction of the suction, so that emissions can not be fully detected. Finally, it can come through Schlabberkoks damage to the suction, which is associated with increased maintenance and repair costs.

The object of the present invention is to provide a coke oven operating machine of the type mentioned above in which the disadvantages of the known coke oven operating machine described above do not occur.

The above object is achieved in a coke oven operating machine of the type mentioned above in that the suction is separated from the coke bucket connected to the Koksofenbedienungsmaschine and that the coke bucket relative to the suction or from the basic position is arranged movable in the Auffangstellung. The coke bucket is arranged to be movable independently of the suction element from the basic position into the collecting position, wherein the suction element is not directly connected to side walls of the coke bucket and wherein the suction element is pivotally arranged from a basic position in the Koksofenbedienungsmaschine process in a suction position when sucking the emissions , As a result, the suction on the one hand and the coke bucket on the other hand can be moved independently. The suction element can be moved with the coke oven operating machine in the longitudinal direction of the master pass. The coke oven operating device provided for catching and removing slag coke at the coke oven operating machine is also movably arranged with the coke oven operating machine in the longitudinal direction of the master run.

The invention is based on the basic idea of designing the coke oven operating device provided for collecting and removing slag coke and the suction device provided for detecting emissions of the coke scoop as structurally separate structural units. Essentially it is that the at least one suction element of the suction device is not directly connected to the coke bucket, which allows, the Coke bucket independent of the suction and to move relative to the suction from the basic position in the Auffangstellung or to pivot.

During the movement of the coke bucket from the basic position to the collecting position and back, the load on the coke oven operating device in the coke oven operating machine according to the invention is significantly reduced due to the lower weight of the coke bucket. Incidentally, the mobility of the coke bucket is not hindered by pipelines of the suction device, which are connected to the suction and are required to remove the emissions from the suction. Finally, in the coke oven operating machine according to the invention, the suction element is preferably always arranged at a distance from the coke shovel so that no clogging of the suction opening or damage to the suction element is to be feared.

In a preferred embodiment of the invention, a line-shaped suction element, preferably a vortex hood, is provided, wherein the suction element is arranged in the collecting position of the coke bucket substantially parallel to a side wall of the coke shovel extending transversely to the master passage. As a result, emissions can be detected effectively, wherein the mobility of the coke bucket is not hindered by the suction. The suction opening of the suction element is arranged in the collecting position of the coke bucket, preferably above the side wall of the coke breech, which also favors the complete detection of emissions. For the same purpose can be preferably provided on each transverse to the master gear side of the coke bucket, respectively, a suction. The suction elements preferably extend over the entire length of one side of the coke bucket, at least they can extend over two-thirds of the length. Finally, in the case of a linear design, for example as a vortex hood, the suction element can be arranged such that it can rotate or swivel about its longitudinal axis. As a result, it is possible to align the suction opening of the suction element with the coke scoop and to turn it outwards or upwards for cleaning purposes. The suction element may be arranged in the basic position and in the Auffangstellung the coke bucket with a substantially equal distance from the bottom of the master gear. The suction is not raised or moved together with the coke bucket as a result. This contributes to a simple structural design of the coke oven operating machine according to the invention and to a high stability.

To derive the detected emissions, the suction is connected via at least one suction with the Koksofenbedienungsmaschine and with a manifold. It is preferably provided to lead the suction on a side facing away from the Koksofenbedienungsmaschine side of an outer railing of the master gear upwards, over the outer railing away. After passing the outer railing, the suction line may then be led down on the side of the coke oven operating machine between the railing of the master gear and the Koksofenbedienungsmaschine towards the bottom of the master gear and there open into a manifold. About appropriate brackets, the pipe can be attached to an outer wall of the coke oven operating machine. This makes it possible to remove the suction device, i. the suction element, together with the coke oven operating machine to proceed, without causing a hindrance in the process by the suction connected to the suction in the region of the master gear. It is understood that the suction line must be arranged sufficiently far from a railing of the master gear, in order to exclude a disability.

The extraction element can be arranged pivotable from a basic position during the process of the coke oven operating machine about an axis preferably extending vertically to the base of the master passage into a suction position for sucking off the emissions. As a result, the suction from the suction position, in which the suction extends at least partially transversely to the master gear at least partially over the master gear, pivot in a basic position, wherein the suction can be arranged in the basic position substantially in the longitudinal direction of the master gear. A disability of a battery maintenance cart which can be moved along the master gear through the suction element can thus be ruled out. in the the rest of a danger to the operator of the coke oven is prevented when moving the coke oven operating machine by pivoting the suction. In principle, it is of course also possible that the suction from a horizontal position in a vertical position to pivot about a longitudinal axis extending substantially parallel to the master gear or swing out of the master gear. As a result, a disability of the battery maintenance cart and a threat to operating personnel are also excluded.

For pivoting the suction at least one pivot drive can be provided, preferably a hydraulically or pneumatically operated piston-cylinder unit. For example, it is possible to provide an actuating cylinder which can be extended in the longitudinal direction of the master gear and which is supported at one end on a housing of the coke oven operating machine and attached with the other end to a suction element of the suction device that is rotatable or pivotable on the suction line. If in each case one suction element is provided on each of the two outer sides of the coke bucket extending transversely to the master passage, then the suction elements can be arranged pivotably in the same pivoting direction from the basic position into the suction position. As a result, the structural design of the inventive coke oven operating machine is simplified and reduces the space required for pivoting the suction. In particular, one of a variety of ways, the erfmdungsge- coke oven operating machine to design and further develop, reference being made on the one hand to the dependent claims and on the other hand to the following description of a preferred embodiment of the invention with reference to the drawings.

The coke oven operating device 1 has a bucket device 4 with a coke bucket 5, wherein the coke bucket 5 in FIG. 1 is arranged in a collecting position for collecting slag coke below a door opening of the coking chamber 3 near the bottom of the master run 2. In the transition region between the interior of the coking chamber 3 and the master gear 2 is a Rut- see 7 is provided on the way in a manner not shown from the interior of the coking chamber 3 during the Ausdrückvorgang escaping Schlabberkoks in the coke bucket 5 of the blade device 4 is transferred. The coke oven operating device 1 shown in FIGS. 1 and 2 corresponds to the coke oven operating device, which is illustrated and described in DE 10 2005 046 543 A1. Reference is made to the disclosure of DE 10 2005 046 543 Al in this respect.

The coke bucket 5 has in the coke oven operating device 1 of the known coke oven operating machine on both transverse to the master gear 2 sides each a linienfbrmiges suction 8, which together with the coke bucket 5 of the Basic position is moved to the Auffangstellung. The direct arrangement of the suction elements 8 on the coke bucket 5 leads to a high total weight of the coke bucket 5, which leads to an increased load on the coke oven operating device 1, in particular of the bucket device 4, during the pivoting process. Moreover, it may come when collecting Schlabberkoks clogging of suction openings not shown, the suction 8 and damage to the suction 8.

In Fig. 3 is a Koksofenbedienungsmaschine 9, namely a Koksausdrückmaschine a coke oven, with a suction device 10 and a coke bucket 11 of a coke oven operating device not otherwise shown, wherein the coke oven operating device for collecting and removing Schlabberkoks in or out of the range of a master gear of the coke oven is formed. The suction device 10 is provided for sucking off emissions released in the region of the coke bucket 11. The coke bucket 11, as in the case of the coke oven operating device described with reference to FIGS. 1 and 2, can be pivoted from a basic position during the process of the coke oven operating machine or from an emptying position into a collecting position for collecting slag coke, wherein the coke bucket 11 is below one in the collecting position Furnace door of the coking chamber near the ground of the master gear is arranged, as shown in Fig. 1.

As is further apparent from FIG. 3, the suction device 10 has two suction elements 12, which are constructed as swirl hoods and each have an elongate suction opening 13 for sucking off the emissions released in the region of the coke scoop 11.

In the embodiment of a coke oven operating machine 9 shown in Fig. 3 it is provided that the suction elements 12 are separated from the coke bucket 11 respectively via pipe sections 14 - 17 connected to a manifold 18 to dissipate the detected emissions. The suction elements 12 together with the pipe sections 14 - 17 and the manifold 18, the suction device 10. It is understood that the Manifold 18 is connected to corresponding exhaust fan or the like. To suck the detected emissions.

In order to keep the burden of the coke oven operating device by the weight of the coke bucket 1 1 during the pivoting movement from the basic position to the catching position low and to reliably prevent damage to the suction 12 and clogging of the suction 13 is in the illustrated in Fig. 3 Koksofenbedienungsmaschine 9 provided that the suction 12 are separated from the coke bucket 11 with the lo coke oven operating machine 9 and that the coke bucket 1 1 relative to the suction 12, ie is arranged independently of the suction elements 12, from the basic position in the Auffangstellung and back pivotally. In Fig. 3, the coke bucket 11 is shown only in the Auffangstellung.

It is understood that the suction elements 12 are not directly connected to side walls 19 - 21 of the coke bucket 1 1 to allow independent mobility of the coke bucket 1 1 relative to the suction 12. It goes without saying that the structure of the coke oven operating device shown in FIG. 3 for collecting and removing slag coke may otherwise correspond to coke oven operating devices known per se in the art for collecting and removing slag coke by means of a coke scoop. 5 The suction device 10 is firmly connected in the region of the arcuate pipe section 16 via cantilevers 22 with a housing part 23 of the coke oven operating machine 9. Thereby, the suction device 10 is moved together with the coke oven operating machine 9 and held with high stability. 0

The suction elements 12 are formed linearly as vortex hoods and arranged in the collecting position of the coke bucket 11 substantially parallel to the side walls 19 of the coke bucket 1 extending transversely to the master passage. In order to allow free mobility of the coke bucket 11, 5 the suction elements 12 are arranged sufficiently far from the side walls 19 so that it does not pivot when the coke shovel 11 is pivoted can come to a disability by the suction 13 überkragende baffle portions 24 of the shell of the suction 12.

The suction elements 12 extend over at least two-thirds of the length of the side walls 19 of the coke bucket 1 1 running transversely to the master run, the suction openings 13 of the suction elements 12 being arranged in the collecting position of the coke bucket 11 above the side walls 19 of the coke bucket 11. This ensures complete extraction of the emissions released in the area of the coke bucket 11.

As has already been pointed out, the suction elements 12 are each connected to the coke oven operating machine 9 via pipe sections 14 - 17, which each form an extraction line. In this case, the suction of a connecting pipe section 14, starting vertically over a further vertically extending pipe section 15 extending upward and guided over an arcuate pipe section 16 via an outer railing 25 of the master gear to Koksofenbedienungsmaschine 9. Behind the outer railing 25, the suction line extends in the region of a substantially vertically arranged pipe section 17 down to the manifold 18. By the arcuate design of the suction with a arranged above the outer rail 25 bow whose bow leg in the vertical direction on both sides of the outer rail 25 after extend down in the direction of the master gear, it is ensured that the suction device 10 can be moved together with the Koksofenbedienungsmaschine 9 in the longitudinal direction of the master gear without obstruction by the outer railing 25.

In addition, it is shown in Fig. 3, that each suction 12 from the suction position shown in Fig. 3 when sucking the emissions in a basic position, not shown in particular in the process of Koksofenbedienungsmaschine 9 to each vertical to the bottom of the master gear extending axis Yi, Y _{2 can} pivot or rotate. In the initial position and in the collecting position of the coke bucket 11, the suction elements 12 each have a constant distance from the bottom of the master run. This contributes to a simple construction of the suction device 10. For pivoting the suction elements 12, the Ab- Suction in each case in the area between the straight pipe section 15 and the arcuate pipe section 16 arranged above a swivel joint 26 on.

This makes it possible to swing the suction elements 12 from the suction position shown in Fig. 3 with an arrangement substantially transverse to the master gear, so that the suction elements 12 are arranged in the basic position substantially in the longitudinal direction X of the master gear. As a result, the master gear is kept clear during non-suction operation of the suction device 10, for example for a battery maintenance trolley which is not shown movable in the longitudinal direction X of the master gear. Also in the method of the coke oven operating machine 9, a hindrance or personal danger by the suction elements 12 is excluded.

For pivoting the suction elements 12 each have a pivot drive 27 is provided, which may be a piston-cylinder arrangement, which can be preferably operated hydraulically or pneumatically. The pivot drive 27 is articulated at one end to the pipe section 15 and supported at the other end to the coke oven operating machine 9. For this purpose, the housing part 23 may, for example, have a housing part section 28 projecting over the railing 25. It is understood that the pivot drive 27 shown on the right side of the suction device 10 in Fig. 3 may be supported accordingly. In addition, it is provided that the suction elements 12 are pivotable in the same pivoting direction z from the basic position into the suction position. For this purpose, the right suction element 12 is located farther from the bottom of the master passage than the left suction element 12, which is achieved by a different length of the pipe sections 15 on both sides of the coke bucket 11.

To collect and remove Schlabberkoks first the coke bucket 1 1 is lowered from the basic position to the collecting position, wherein the coke bucket 11 is arranged in the collecting position below an oven door of the coking chamber of the coke oven near the bottom of the master cast. Subsequently, the two suction elements 12 are pivoted from the basic position into the suction position, so that the shown in Fig. 3 Position is reached. Subsequently, the oven door is opened and thereby emerging Schlabberkoks collected in the coke bucket 11. At the same time, the extraction of emissions takes place via the suction elements 12. The suction elements 12 are then pivoted back into the basic position and the coke scoop 11 is swiveled into the emptying position.

The exhaust elements 12 designed as swirl hoods are mounted pivotably about bearing elements 29 about their longitudinal axis. This makes it possible to change the orientation of the baffle sections 24 accordingly to ensure an optimum detection of emissions. Moreover, the pivotability of the suction elements 12 allows the suction opening 13 to be turned upwards or outwards as required to remove sludge coke constituents which may block the suction opening 13 from the region of the suction openings 13.
