Description

Coke oven manipulator

technical field

The invention relates to a coke oven operating machine for a coke oven having a plurality of coking chambers arranged side by side, the coke oven operating machine having a suction device for suctioning the emissions from the opened coking chambers, There is also a door lifting device and possibly further coke oven handling devices, wherein the coke oven handling machine is arranged movable relative to the coking chambers along the main channel of the coke oven for operating the coking chambers.

Background technique

A coking oven consists of a plurality of coking chambers of sheet-like configuration arranged side by side in a long row. After the coking process of the coal, the coke is pushed out of the furnace with a coke pusher. For this purpose, the coke pusher automatically opens and closes the furnace door on the side of the coke pusher and flattens the coal that is filled into the coking chamber by the stoker. The coke pushed out of the furnace by the coke pusher is guided to the quenching car through the coke arresting equipment integrated on the coke conveyor. Normally, the opening and closing of the furnace door required on the side of the coke conveyor is automatically performed by the coke conveyor.

It is known in the prior art that, in order to collect the emissions, above the coking chamber, on the coke oven manipulator, a suction device movable together with the coke oven manipulator is provided, which can be connected to a fixed suction line on the machine side. Via this fixed suction line, the discharge is conveyed to a fixed central dust extraction system (Endstaubungseinrichtung). Thus, it is possible to suck up accumulated emissions which are released in the coke oven door when it is opened, during subsequent cleaning of the door and frame, when coke is pushed out of the oven and when the coke oven door is closed again. In the area of the coking chamber to be operated respectively.

Between the coking chamber of the coke oven and the coke oven manipulator, the emissions released in the area of the coking chamber to be operated can form a vortex on both sides of the coke oven respectively along the main channel (Meistergang) due to the influence of the wind, Instead, the discharge is partially blown laterally out of the suction region of the suction device. Finally, in the presence of side winds, the suction equipment provided on the coke oven manipulator cannot be used to ensure complete suction of the released emissions. Uncollected emissions are a burden to the coke oven operator and the environment and can cause health damage.

Contents of the invention

The object of the present invention is to provide a coke oven operating machine of the type mentioned at the outset, which ensures that when the coke oven door is opened, during the subsequent cleaning of the door, when coke is pushed out of the oven and when the coke oven door Efficiently collects released emissions when closed.

In a coke oven handling machine of the type mentioned at the outset, the above-mentioned object is solved by the coke oven handling machine provided by the invention. In the coke oven operating machine of the present invention, in order to shield the wind of the main channel in the coking chamber area to be operated, at least two windproof walls adjacent to each other for forming a shielded area are arranged, and the windproof walls face toward The direction of the coking chamber extends at least partially and substantially across the main duct, the suction device, the door lifting device and possibly further coke oven handling devices are arranged between the adjacent draft protection walls space, and the windbreak walls are spaced apart from one another in such a way that the door lifting device and, if applicable, the further coke oven handling devices can be operated inside the shielded area.

The basic idea of the invention is to protect the main channel of the coke oven from the side winds that occur along the main channel between the coke oven and the coke oven manipulators, at least in the region of the coking chambers operated separately by the coke oven manipulators. Impact. When the coke oven handling device is moved along the main channel, the shielded area defined by the adjacent windbreak wall of the coke oven handling machine is displaced into the part of the coke oven in which the coking chamber to be operated is arranged. This ensures that the emissions released during the operation of the coking chamber are always substantially completely collected by the suction system of the coke oven handling system. The invention minimizes the environmental burden caused by emissions and the health hazards to operators.

In this regard, it should be pointed out that according to the invention adjacent windbreaks are spaced apart from one another at least in such a way that coke oven operating equipment, such as door opening equipment and/or frame and door cleaning equipment and/or main channel cleaning equipment and/or for collecting The collection facility for remaining level coal and overflow coal can be operated between adjacent windbreak walls without the windbreak walls interfering with the operation of the coke oven handling plant. The windshield walls are at least so far apart from one another that the operation of the door opening device can be uninterrupted. The suction device of the coke oven operating machine according to the invention is arranged above the oven door of the coke oven in a manner known per se from the prior art and moves together with the coke oven operating machine towards the corresponding coking chamber to be operated. The machine can be a coke pusher or a coke conveyor.

According to the invention, the length of the shielded area in the direction of the main channel is determined such that preferably all coke oven handling equipment of the coke oven manipulator provided for operating the coking chamber can be operated without problems in the shielded area. Therefore, the necessary length of the shielding area depends on the structural shape and size of the coke oven, the coke oven operating machine and the coke oven operating equipment arranged on the coke oven operating machine. In order to ensure undisturbed operation of the coke oven operating plant, the distance between adjacent windbreak walls may correspond to the total width of at least three adjacent coking chambers, preferably four to ten adjacent coking chambers, In particular, it corresponds to the width of five adjacent coking chambers.

Preferably, the draft wall extends upwardly from the bottom of the main channel at least beyond the height of the oven door of the coking chamber. This ensures that, at least up to the height of the oven door, no swirling of the exhaust gases emerging from the open coking chamber due to the influence of the wind is possible. This enables complete collection of the emissions by the coke oven handling equipment of the coke oven handling machine arranged above the oven door.

In order to shield the side winds to a greater extent, and to ensure a more effective suction of the released emissions, at least one windbreak wall, preferably two windbreak walls, start from the bottom of the main channel and in any case at least from The lower region of the oven chamber extends upwards at least to the level of the suction device, or beyond.

In the transverse direction, the two windshield walls preferably extend from the coke oven manipulator through the main duct substantially as far as the anchor bracket of the coke oven or as far as the oven wall of the coke oven. At least in the stationary state of the coke oven manipulator, the windbreak wall can rest on the anchor bracket or the furnace wall. This helps prevent side winds from passing sideways over the windshield wall and gushing into the shielded area. As a result, swirling of the emissions from the open coking chamber by side winds is avoided as much as possible in the shielded area.

For maintenance and servicing, a battery maintenance cart (Batterie Wartungswagen), which can be moved along the main aisle, is preferably provided for the furnace door. In order to facilitate the passage of the battery maintenance vehicle, it is preferred that the two windshield walls can be hinged on the coke oven operating equipment in a reversible or rotatable manner, or can leave the coke oven in the lateral direction and move linearly towards the coke oven Connected with the coke oven operating machine. In this way, the battery maintenance vehicle can be driven into and out of the shielded area in a simple manner without the movement of the battery maintenance vehicle along the main passage being hindered by the windbreak wall.

In order to enable the battery maintenance vehicle to be driven in and out, the windbreak wall is preferably pivotably hinged in two directions or is movably connected to the coke oven operating machine. Here, the windbreak wall must be pivotable at least so far, or articulated or connected to the coke oven manipulator, that it can be moved so far away from the coke oven, that after being turned or moved, the distance between the windbreak wall and the anchor bracket of the coke oven The distance between them corresponds at least to the width of the battery maintenance vehicle, preferably taking into account an additional safety distance. The battery maintenance cart may have a width of about 1.0m to 1.5m, wherein the safety distance should be about 0.5m. In the case of a pivotable windbreak wall, it is important in this respect that sufficient free space is provided on both sides of the windbreak wall in order to fully ensure that the windbreak wall can be folded away or rotated. In this case, the coke oven handling equipment of the coke oven handling machine, for example, must not impede the opening of the windbreak wall. The same applies correspondingly when the windshield is connected to the coke oven manipulator so that it can move away from the coke oven.

It is not necessarily necessary that the draft protection wall is pivotable or rotatable over its entire height, or is articulated on or connected to the coke oven manipulator so as to be movable away from the coke oven. For example, it is possible to divide the windshield into two parts, of which only the lower part is hinged or connected so as to be pivotable or movable away. However, the lower part must have at least such a height that it is possible to pass battery maintenance vehicles or other devices that are movable relative to the coke oven operating machine. However, it is preferred that the windbreak wall is tiltable or displaceable over its entire height.

The windbreak walls preferably have very little dead weight, so that they can be opened or moved in a simple manner. In addition, the low dead weight facilitates the articulation of the windbreak wall to the coke oven manipulator or the low load on the movable connection.

In principle, it is also possible that at least one windshield wall has at least one wall section that can be tilted or moved laterally away from the coke oven so that the battery maintenance vehicle adjacent to the coke oven can be moved along the main passage. The opening formed by the windbreak wall after the wall part has been turned over or moved has at least such a height and width that it corresponds to the height and width of the battery maintenance vehicle, preferably taking into account the safety distance.

A control device can be provided for automatically turning or rotating and/or moving the windbreak wall or wall sections. The control device can be designed in such a way that the windbreak wall or wall parts are automatically tilted and/or moved, preferably before the battery maintenance vehicle comes into contact with the windbreak wall. In this respect, a correspondingly designed measuring device (Messtechnik) or sensor device can be provided in order to measure the distance between the windbreak wall and the battery maintenance vehicle. The turning-over process and/or movement control of the windbreak wall or wall parts can preferably be carried out in such a way that no contact between the battery maintenance vehicle and the windbreak wall and/or wall parts can occur during the passage of the battery maintenance vehicle. Damage can thus be avoided. In principle, of course, it is also possible for the battery maintenance vehicle to press the wall or the wall part away when it comes into contact with the windshield wall or the wall part.

In a particularly simple embodiment of the invention, the windshield or the wall part is spring-loaded (federbelastet), wherein the windshield or the wall part is swung back or moved back into the shielding position after the battery maintenance vehicle has passed due to spring force . In principle, however, it is also possible to provide a drive unit for pivoting and/or moving the windbreak wall or wall parts, which drives the windbreak wall or wall parts to be turned back or moved back after the battery maintenance vehicle has passed by. For example, a chain drive can be provided as drive.

In order to enable coke oven operators to pass through the windshield, the windshield can have a passage opening, preferably adjacent to the coke oven manipulator. In this aspect, the passage opening has at least a width such that a person can transition from one side of the windbreak wall to the other along the main passage. Furthermore, the passage opening can have such a width that it also enables the passage of the lifting platform. In this respect, the passage opening has a maximum height of 2.0 to 3.0 m, preferably 2.5 m. In order to prevent discharges from escaping from the shielded area into the environment, sheet-like curtains or further wall parts of the windshield that can be tilted or rotated and/or moved laterally can be provided in order to at least partially close the passage opening.

The suction opening 7 of the suction device 3 is aimed at the coke oven 2 for collecting when opening the coke oven door 8, during subsequent cleaning of the coke oven door 8 and the door frame, when pushing coke out of the coking chamber to be operated and Emissions produced when the coke oven door 8 is closed again. The suction device 3 can be a vortex hood suction device.

Due to the influence of the wind, in particular due to side winds or transverse winds which may occur along the main channel 5 between the coke oven manipulator 1 and the coke oven 2, eddies may be caused in the emissions from the open coking chamber, so that It is only partially or not collected by the suction device 3 at all. The emissions cause unnecessary environmental burdens and lead to health hazards for coking plant operators. Therefore, according to the invention, in order to shield the main channel 5 in the area of the coking chamber to be operated from the wind, at least two adjacent wind-resistant walls 9 are provided for forming a shielded area 10 in the direction of the coking chamber Extending substantially across the main channel 5 at least partially, the suction device 3 and the door lifting device 4 and possibly further coke oven handling devices are arranged between adjacent windshield walls 9 which are thus spaced apart from each other , so that within the shielded area 10 the door lifting device 4 and possibly further coke oven handling devices can be operated between adjacent windshield walls 9 .

A distance a is preferably set between the anchor bracket 11 and the front edge of the windbreak wall 9, which ensures that when the coke oven manipulator 1 moves longitudinally along the main channel 5, the windbreak wall 9 and the coke oven 2 through the contact between the parts of the anchor bracket 11 protruding towards the coke oven manipulator 1. In principle, it is of course also possible for the windshield 9 to extend transversely over the main channel 5 so far that the windshield 9 rests on the anchor bracket 11 at least in the stationary state of the coke oven manipulator 1 .

Furthermore, FIG. 3 shows that the windshield 9 has a passage opening 12 on the side opposite the main passage 5 in order to allow coke oven operators 13 to pass through the windshield 9 , for example in an emergency. The passage opening 12 can have a height of preferably 2.5 m and a corresponding width in order to also allow the passage of lift trucks moving along the main passage 5 . In order to effectively shield against side winds, the passage opening 12 can have a lamella curtain 13 , which is designed in such a way that the influence of the wind is substantially prevented and persons can enter or exit the shielded area through the lamella curtain 13 .
