Description

[Detailed description of the invention] Coal cake horizontal coking The present invention is designed to be manufactured outside the coking chamber in the tamping mold of a tamping-cum-inserting-extruder. The coal cake on top of the movable tamping bottom of the ramming type is horizontally coked. A device for preventing fill gas from escaping during entry into a chamber, the device The door frame of the coking chamber is closed at the open end side, surrounding the coal cake into which the coal cake enters. It relates to a type of passage configured as a passageway that comes into contact with the system.

According to German Patent No. 2,821,169, the furnace opening and the intruding protrusion Sealing frames surrounding the cake are known. This seal frame has a pivot of the head of the cake to be run through the tamping mold from a lateral position. Can be brought before. The rotating arm itself is a stand that can run parallel to the furnace axis. It is placed on the car and can be moved until it reaches the furnace opening. This known file The frame does not bridge the entire space between the coking chamber and the compaction mould. rather tamping The seal on the mold side is placed in the seal frame and is in direct contact with the incoming coal cake. This is done by means of a contacting elastic sealing member.

In practice, sealing members that come into direct contact with the coal cake have major drawbacks. resulting in impaired driving. One of the reasons for this is the relative interaction between the coal cake and the sealing member. However, another cause is that the seal member is located directly in front of the open coking chamber. Based on the fact that the sealing elements are exposed to extremely high operating temperatures, is made brittle.

Another disadvantage of sealing members that are in close contact with the coal cake is that the coal cake may become stuck. If only partially penetrated, remove residual cake and return to tb tamping equipment. This means that it cannot be transported. Insertion direction specified for friction seals On the other hand, when the coal cake is transported back, the friction sealing device A damming occurs. This is because the coal cake gets caught in the coking chamber and changes. This is because it no longer forms a well-shaped and exact square.

In terms of construction, the known device is very complex and can be swiveled back and returned. Placing the transported 7-le frame next to the tamping mold is a big problem in terms of location. bring about. This is because in this range there are other parts on both sides of the tamping mold, e.g. Compact type driveable front door, insert block locking device, coking chamber door. This is because a movable lifting device and door frame cleaning device are installed. Ru.

According to German Patent No. 2943519, therefore, the sealing frame It has already been proposed to place the door directly in front of the rammed door. In this case, stationary frame is fixed in front of the tamping mold, whereas the original cover frame It can be pre-swiveled forward and downward via a parallelogram guide.

coking by the stationary part of the equipment, except that Between the chamber and the anchor stand of the tamping/insertion/extrusion machine (so-called 5BA-machine) The disadvantage is that the gap, or Meistergang, is significantly narrowed. But long 5RA- In order to avoid danger to the operator when operating the aircraft, additional precautions must be taken. Slides must ensure a sufficiently wide passageway for safety. on the other side In this case, the total distance between the coking chamber and the compaction mold, and the exposed coal cake. It is desirable to keep the distance that must be traveled as small as possible. Ru.

The problem of the present invention is that when the coal cake enters the coking chamber in the horizontal direction, the charging gas equipment that does not have the above drawbacks, functions easily to avoid leaching It is to provide.

The problem is that in the type of equipment mentioned at the beginning, the side wall of the passage is of the tamped type, and the furnace side The enclosure can be run into the side wall configured as a hollow wall, and the bottom of the passage is a protrusion that can be run. It is formed with a hard bottom, and the passage cover is configured to allow telescopic movement. with guides for the movable side walls, in this case the fixed part of the passage cover. Smooth the surface of the coal cake, with a removal device for scraped coal in minutes This problem was solved by installing a leveling device.

Forced entrainment means are preferably provided between the side walls of the passage and the telescoping passage cover. , for example, when a spring-loaded friction surface runs through the telescope section together with the side wall of the passage. It is provided to make the driver run faster. This provides a unique drive for the passage cover. moving devices can be avoided.

The side walls of the passage are directly connected to a movable tamping base or a tamping base drive. It's okay. In this case too, a separate drive can be omitted.

Runs out before the coal cake runs in and is supported on a bracket in the furnace chamber. As long as the tamping bottom support is present, the side walls are advantageously connected to the tamping bottom support. He is forced to run. In this arrangement, the passage side walls and the passage cover are connected to the coal cake itself. It has already been run out and brought into contact with the coking chamber door frame before being inserted. It has the advantage of being This turns the cake head into a hot coking chamber. The filling gas, which is already generated during the approach, is clearly assisted by the flue effect that is formed. In fact, it will be removed.

Removal of the filling gas is carried out in a known manner through gas outlets and connections arranged in the canopy of the coking chamber. It is carried out to the gas treatment equipment via the gum collection pipe installed above the gas furnace . The discharged filling gas is transferred to a filling gas combustion truck that can run on a coke oven bed. or in an adjacent coking chamber filled with coal. It is said that the passage surrounding the incoming coal cake will avoid emissions when Besides the advantages, uncontrolled air coking along with the filling gas are drawn together through the chamber, significantly impairing the ignition properties of the charge gas and This has the advantage of avoiding interfering with proper combustion. run in The amount of combustion air supplied by sealing the coal cake can be adjusted to suit the purpose. , can be adjusted accordingly to the true requirements.

The device of the present invention does not require a friction seal device that contacts the incoming coal cake itself. It disappears. In this case the lateral seals are located within the tamped side walls, on the passage side walls. This is done by means of a sealing strip in contact with the The downward sealing is done by a tamped bottom. be called. On the surface of the cake, the seal is the stone scraped off by the leveling device. This is done by coal ridges formed by charcoal.

For sealing against the door frame of the coking chamber, it is advantageously spring-loaded. Edge strips are provided. The edge strip may be It consists of edge strip segments that can adapt to the irregularities of the door frame. I can do it.

In the entry position, the device according to the invention reduces the air space between the coking chamber and the SBA machine. Neither the space nor the space next to the SBA aircraft will be obstructed in any way. Teles When the coop movable passage cover is moved in, it is placed on top of the Meistergang in front of the tamping mold. However, depending on the cake height, it is located at a height of approximately 4 to 6 m. , so it shouldn't be a problem.

To monitor the insertion process, the channel cover can be equipped with a pressure probe. child The pressure sonde is blocked when the coal cake is locked when attempting to insert it. The insertion process is interrupted under the influence of the pressure created by the coal.

According to one embodiment of the device according to the invention, the passage can be provided with an additional gas outlet. I can do it. This gas outlet is installed permanently above the canopy of the coke oven battery. The 8BA- It can be connected to a combustion chamber that can travel with the aircraft.
