Description

HANDLING DEVICES OF COKE OVEN HANDLING MACHINE AND METHOD FOR HANDLING COKE OVEN THEREBY}

The present invention relates to various coke oven manipulation devices of a coke oven manipulator for operating a coke oven in which a plurality of coking chambers are arranged next to each other according to the preamble of claim 1.

The present invention also relates to various methods of operating a coke oven with a coke oven manipulator according to the preamble of claim 8 in which a plurality of coking chambers are arranged side by side.

Each type of coke oven manipulator, and the method of operating the coke oven by the coke oven manipulator, which are premised at the outset, are actually known for several decades. In such a known method, after the coking process, the coke oven door of each coking chamber is opened by the door jack device. To this end, the door jack device has a door jack provided with a corresponding means (hook) which serves to engage in a pocket-like corresponding opening in the door. In that case, the opening is provided with a predetermined gap, so that the hook can be engaged in the opening to open the door with coke even when the door jack is contacted without being centered. After opening the door, the coke cake guide of the coke cake guide device is brought into contact with the extrusion side to the coke for bridging with the main passage located in front of the coking chamber and the extruded coke is dropped into, for example, a coke unloading vehicle. . Extruding coke from each coking chamber is effected by an extrusion apparatus with a pressure head formed in a stamp form.

After extruding coke from each coking chamber, it is necessary to clean the sealing surfaces on the doors and frames of the coke oven of each coking plant, because the deposits and other impurities generated during the coking process are sealed. This is because it is deposited on cotton. Such deposits should be removed as they may impede the gastight closure of the coking chamber. In cleaning the frame of the coking chamber, a frame cleaning device provided with a frame cleaner for contacting or inserted into the frame to clean the frame is used. At the same time, the removed coke oven door is transferred to a door cleaning device in the coke oven manipulator for cleaning. After the cleaning process is completed, the door is inserted back into the frame to close the coke oven.

The coke furnace of the type described above consists of a plurality of coking chambers formed in a disc shape and arranged next to each other in elongated rows, in which case the axis of these coke oven sets is usually the longitudinal axis of the individual coking chambers or the coke oven axis. Extends across. Ideally, the individual coking chambers would each be placed vertically. That is, the axis of the coke oven is located in the vertical plane. Of course, there may be a case where the coking chamber is oriented to a position off the vertical. The misaligned or inclined position of such coking chambers, known from decades ago, is characterized by the vertically oriented door jacks when the door is removed and the frame being cleaned, and similarly the vertically oriented frame sweeper by means of the corresponding drive mechanism. Or it is pushed into the frame to remove the door or by cleaning the frame is eliminated. In that case, damage can occur in particular in the region of the frame. The same problem occurs when the door is refitted with coke. In that case too, the door is pushed with a corresponding pressure into the frame of the obliquely oriented coking chamber with coke held vertically by the door jack. As described above, by pushing the frame sweeper or coke oven door into the frame, the frame as well as the coke oven door are also damaged or deformed, so that in such areas the sealability of the coking compartment is no longer guaranteed and the contaminant emissions caused by it May cause problems. The larger the inclined position of the coking chamber frame or the coking chamber frame, the greater the problem caused by the coke oven operating device.

It is an object of the present invention to provide a coke oven manipulator of the coke oven manipulator and coke oven of the type presupposed in the beginning that the problem of pollutant discharge due to leakage from the coke oven door and each frame no longer occurs and the correct operation is ensured. It is to provide an operation method.

The object derived above is achieved by the features of claim 1 with respect to the apparatus and by the features of claim 8 with respect to the method.

According to the present invention, an individual coke oven manipulator which is disposed on the coke oven manipulator and is brought into contact with or inserted into each coke fire chamber is adjusted to the respective inclined position of each coke fire chamber to be the same as the inclined coke fire chamber. It is guaranteed that it can be in an inclined position. Thereby, a force that can cause damage to the door by the frame or the individual coke when removing or reinserting the door, when contacting the coke cake guide, when cleaning the frame, and when the pressure head is inserted, is applied to the coking chamber. It is guaranteed not to be applied to the frame of. Correspondingly, the frame is treated with care so that no damage or deformation of the frame occurs and, as a result, no more leakage in the area of the frame. It is also important that the present invention can be realized not only in old installations but also in new installations so that the frames and coke oven doors of the individual coking chambers are treated with care.

In a preferred configuration of the present invention, the door jack, coke cake guide and frame sweeper are jointly supported starting from an axis parallel to the axis of the coke oven at their respective upper ends. Basically, the support for turning according to the invention preferably passes through the center points of the door jack, the coke cake guide and the frame sweeper. However, because the coke is guided through the coke cake guide, it is difficult for the support to support it centrally. Therefore, with regard to the coke cake guide, it is particularly suitable to support the pivot at the upper end of the coke cake guide anyway. Since the coke oven manipulator is not normally operated in the coking chamber during operation, it is better to jointly support the frame sweeper and the door opener in the same form as the coke cake guides, preferably by cardan joints or ball / socket joints. good.

On the other hand, in coke oven manipulators without coke cake guides it is basically suitable to pivotally support the door opener, frame sweeper and / or pressure head.

In order to realize such turning, the servo jack is attached to the door jack, the coke cake guide, the frame sweeper and the pressure head, respectively. The servo device is equipped with a tripod measuring device to set the respective turning angles necessary to match the inclined position of each coking chamber, so that the required turning can be adjusted with millimeter precision. In that case, a simple configuration is that the servo device has one or more hydraulic cylinders. The hydraulic cylinder acts on the part which cannot be turned of each device on one side and on the part to be turned on the other side. It is a configuration that always applies with regard to door jacks and frame cleaners. In the case of the coke cake guide, the servo device may be configured differently. In such a configuration, the hydraulic cylinders act on the outer sides of both sides of the coke cake guide, in which case the two hydraulic cylinders are fixed to the non-rotatable portion of the coke cake guide device, and the cylinder head is provided on each outer side of the coke. It is preferable to move in the guide part of a cake guide, respectively. An appropriate roll may be arranged in the cylinder head to facilitate the movement of the coke cake guide.

Basically, the coke oven manipulator according to the present invention may be provided with a sensor device for optically detecting the turning angle from the vertical of each coking chamber. In that case, the individual devices are pivoted in dependence on the respective angle of inclination sensed, in particular in accordance with the angle of rotation updated according to the angle previously detected. In a more simple and semi-automatic configuration, a control device is provided for manually inputting and storing the turning angle of the coking chamber with respect to the vertical. In such a case, the turning angles of the individual devices are set and memorized manually depending on the inclined position of each coking chamber, when the coke oven maneuvers turn each device to the previously set angle upon reaching the corresponding coking chamber. . Such a configuration is suitable because it is found that the inclined position of the undesired coking chamber is made very smoothly and only a new rotation angle needs to be adjusted only occasionally.
