Description

  Even when the coke oven pitch changes due to aging of the coke oven or when the coke oven pitch is changed due to the new installation of the coke oven, the extruder can be aligned according to the change or change amount. The present invention relates to a leveling apparatus and an operation method thereof.

  In a chamber-type coke oven (hereinafter, also simply referred to as “coke oven”), a number of combustion chambers for carbonizing coal to coke and combustion chambers for supplying heat to the carbonization chamber by combustion of fuel gas are alternately arranged. ing. Normally, a coke oven of one furnace group is composed of about 50 carbonization chambers, and the direction in which the carbonization chambers are connected is called the furnace group direction.

  In the actual operation of the coke oven, the kiln operation is performed by dividing the carbonization chamber into five blocks at a pitch of 5 kilns. For this reason, the extruder includes an extrusion discharge device for extruding red hot coke from the carbonization chamber and a leveling device for leveling the surface of the coal charged into the carbonization chamber after the coke is extruded. The apparatus is installed at intervals of 5 kilns in the furnace group direction.

  If both are placed at a predetermined interval, the extruder is moved in the direction of the furnace group, and the extrusion discharge device is aligned with the center of the carbonization chamber (hereinafter also referred to as “extrusion kiln”) for extruding and discharging red hot coke. The leveling device is positioned at the center of the carbonization chamber (hereinafter also referred to as “coal kiln”) in which the coal is charged after the previous extrusion. In this way, the kiln discharge operation is configured such that in the extrusion kiln, the coking operation of the coal charged by the leveling device can be performed simultaneously with the extruding operation of the red hot coke by the extrusion discharge device.

  The main function of the leveling device of the extruder is to open the small lid attached to the top of the furnace lid of the coal kiln, and to level the coal top surface by inserting a leveling beam into the furnace from the opened small lid. And closing the small lid after the leveling beam is pulled out of the furnace. In order to perform these functions, the leveling device is usually composed of devices such as a leveling beam, a receiving roller, a leveling beam driving device, a small lid opening / closing device, and a small lid connecting chute.

  In recent years, in a coke oven, the deformation of the furnace body has progressed with aging due to long-term use, and in particular, the occurrence of inclination in the carbonization chamber near the end of the furnace group has been recognized, and the inclination of the carbonization chamber exceeds the limit When the extrusion discharge device is aligned with the center of the extrusion kiln, the center of the leveling device will be displaced from the center of the charcoal kiln, and the leveling beam of the leveling device cannot be inserted from the small lid of the charcoal kiln. Things can happen.

  If the above situation occurs, align the extrusion discharge device with the center of the extrusion kiln and extrude red hot coke, then move the extruder again and align the leveling device with the center of the coal kiln. It will be necessary. For this reason, the extruding operation of the extrusion kiln and the leveling operation of the charcoal kiln cannot be performed at the same time, so that the kiln leaving operation is significantly delayed, and the productivity is remarkably lowered.

  In order to solve such a problem, Patent Document 1 discloses that a roller pedestal of a smoothing beam receiving roller is slidably installed in the direction of the furnace group, and a driving mechanism is provided on the roller cradle at the proximal end of the leveling beam. After aligning the extrusion discharge device once with the leveling device, the leveling beam is moved horizontally in the direction of the furnace group, the distance between the extrusion discharge device and the leveling device is adjusted, and the extruder is moved. There has been proposed an extruder leveling device that can align the leveling beam with the coal-fired kiln without causing it.

  FIG. 1 is an explanatory view of a main part of a leveling beam horizontal movement mechanism provided in a leveling device for an extruder proposed in Patent Document 1. In FIG. The leveling device of this extruder is such that only the leveling beam 13 and the receiving roller 14 are slidable in the direction of the furnace group by the slide member 6 among the devices constituting the leveling device. The device, the small lid opening / closing device, the small lid connecting chute, etc. (not shown) are fixedly installed as usual. For this reason, there are restrictions due to various device structures.

  The first restriction is caused by a positional deviation between the leveling beam and a driving device for inserting the leveling beam into the furnace (hereinafter referred to as “leveling beam driving device”). Normally, the leveling beam is driven forward / backward by an electric motor, so both ends of the wire rope wound around the cylindrical drum are fixed near the front and rear ends of the leveling beam, and the rotating drum is rotated forward or reverse. Is done by letting For this reason, if the leveling beam driving device is fixedly installed, the position of the leveling beam and the leveling beam driving device will not shift when the leveling beam slides in the direction of the furnace group and changes its position. Will occur. There is no problem when the above-mentioned positional deviation is small, but smooth driving operation becomes difficult when the positional deviation is so large that the wire rope is detached from the rotating drum.

  The second restriction is caused by a positional shift between the small lid of the carbonization chamber and the small lid opening / closing device. The leveling beam is inserted into the carbonization chamber by opening a small lid attached to the upper end of the furnace lid that seals the carbonization chamber. The small lid is opened and closed using a hook of the small lid opening / closing device. The small lid is opened by hooking the hook on the lever of the small lid, and after the leveling operation is completed, the small lid is closed by removing the hook, but the variation in the carbonization chamber pitch dimension is larger than the width of the lever of the small lid. When the size is increased, the hook of the small lid opening / closing device is not hooked on the small lid, and the small lid cannot be opened and closed.

  Thus, the smoothing device of the extruder proposed in Patent Document 1 can perform a smooth operation corresponding to the amount of change when the variation of the carbonization chamber pitch dimension due to the inclination of the carbonization chamber is small. As the coke oven ages, fluctuations in the pitch of the coking chamber become significant, and when the coke oven exceeds a certain limit, smooth operation of the coke oven becomes difficult.

  Recently, it has been studied to newly construct a coke oven having a coking chamber pitch dimension different from that of the existing coke oven adjacent to the existing coke oven. When the existing furnace and the new furnace are adjacent to each other, it is usually aimed to reduce the equipment cost by sharing the incidental equipment as much as possible. When used in common with the existing furnace, it is necessary to align the leveling device for each of the carbonization chambers of the new furnace, making it difficult to perform smooth kiln work.

  As described above, in order to perform smooth kiln operation with an extruder in response to the aging of the coke oven and the change in the carbonization chamber pitch size accompanying new installation, there remains a problem that must be solved. Yes.

Japanese Utility Model Publication No. 04-97829

  The present invention has been made in view of the above-mentioned problems, and is a case where a change in the coking chamber pitch dimension due to the aging of the coke oven or a change in the coking chamber pitch size accompanying the newly installed coke oven occurs. However, the coke oven extrusion can be performed in synchronization with the kiln work without the need for alignment due to the movement of the extruder, and can prevent the decrease in productivity due to the delay of the kiln work. The purpose is to provide a machine leveling device and its operating method.

  As described above, if the variation of the coking chamber pitch dimension is within a certain range, it can be handled by the leveling device of the extruder proposed in Patent Document 1, but the variation of the coking chamber pitch dimension is also possible. If the limit is exceeded, the leveling device of the extruder proposed in Patent Document 1 cannot cope. As a means for solving this problem, not only the leveling beam and leveling beam receiving roller, but also all devices constituting the leveling device including the leveling beam drive system, the small lid opening / closing device and the small lid connecting chute Although it is appropriate to translate each device in the direction of the furnace group, if each device is translated individually, a moving device is required for each device, which requires installation costs and a complicated structure that causes failure. It becomes a factor of.

  As a result of repeated studies, the inventors have found that a leveling device comprising a leveling beam, a leveling beam receiving roller, a leveling beam driving motor, a small lid opening / closing device, and a small lid connecting chute is directed to the furnace group. If the leveling device is mounted on a common slide base and all the devices constituting the leveling device are translated with the same amount of translation and parallelism, the positional relationship of each device is It has been found that a leveling device that can cope with fluctuations in the carbonization chamber pitch dimensions without change is obtained.

  Furthermore, when performing a new kiln operation, for example, by determining the required movement amount of the slide frame based on the pitch dimensions of all the carbonization chambers over the furnace group recorded in advance in the previous operation, the movement of the slide frame is determined. Has been found to be able to be performed during the movement of the extrusion discharge device, and a smooth kiln exit operation can be performed.

The present invention has been completed on the basis of the above knowledge, and the coke oven extruder leveling apparatus (1) and (2) below and the coke oven extruder leveling (3) and (4) below. The gist of the operation method of the shishi device.
(1) In a leveling device used in an extruder provided with an extrusion discharge device and a leveling device for a coke oven, and disposed at a predetermined interval from the extrusion discharge device on a floor on which the extruder is placed, A floor driving device that enables the floor on which the extruder is placed to move in the direction of the furnace group, a slide frame that is mounted on each of the devices constituting the leveling device so as to be movable on the floor, and the slide frame is a furnace A leveling device for a coke oven extruder, comprising: a slide drive device that is movable in a group direction.
(2) In the leveling device for the coke oven extruder described in (1) above, it is desirable that the slide drive device is a hydraulic cylinder.
(3) Using the coke oven extruder leveling device as described in (1) or (2) above, based on the total chamber pitch dimensions over the furnace chamber recorded during the previous kiln exit operation, Along with moving the extrusion discharge device after finishing the discharge operation, the leveling device is a method of aligning with the carbonization chamber to be the subject of the carbonization work, and when performing the next carbonization chamber kiln operation, The movement distance from the carbonization chamber where the extrusion operation of the extrusion discharge device is completed to the carbonization chamber where the next extrusion operation is scheduled is measured, and the previously recorded carbonization chamber pitch dimension corresponding to the movement distance and the extrusion operation are measured. Compared with the previously recorded carbonization chamber pitch dimension corresponding to the movement distance measured at the time of exiting the carbonization chamber in the finished carbonization chamber, the difference between the two was calculated, and during the movement of the extrusion discharge device, Charging work based on the calculated dimensional difference Operation method of leveling device of the coke oven extruder, characterized in that aligning the carbonization chamber of interest.
(4) In the operation method of the leveling device of the coke oven extruder described in (3) above, a rotary encoder that is operated by floor driving wheels can be used for measuring the moving distance.

  The leveling device for the coke oven extruder described in the above (1) and (2) can not only perform alignment corresponding to fluctuations in the coking chamber pitch dimension, but also each device constituting the leveling device. By moving all at once instead of individually translating, it is possible to reduce the frequency of equipment failures and the number of inspection and maintenance locations, and to reduce management costs.

  FIG. 2 is a work flow diagram showing the operation method of the leveling device of the coke oven extruder of the present invention. The operation method of the leveling device of the coke oven extruder described in (3) above is described in accordance with the work flow diagram shown in FIG. To do.

  As described above, since the coke oven kiln operation is performed at a pitch of 5 kilns, the extruder is sequentially moved in order to align the extrusion discharge device to the first, sixth, and eleventh carbonization chambers. Go (S2). At that time, the moving distance (for example, the distance between the centers of the carbonization chambers from No. 1 to No. 6) of the 5 kiln pitches of the extruder is measured (S4), and the remaining carbonization chambers are sequentially recorded in the same manner. (S5).

  For example, when an extrusion operation is performed in the carbonization chamber No. 6, the leveling operation is simultaneously performed in the first carbonization chamber. The extruder is moved to align the position from the number carbonization chamber to the number 11 carbonization chamber (S2).

  At this time, the leveling apparatus moves from the first carbonization chamber to the sixth carbonization chamber. The movement distance of the extruder recorded at the time of the previous kiln operation, the carbonization chamber pitch dimension from the first carbonization chamber to the sixth carbonization chamber (S11), the carbonization chamber from the sixth carbonization chamber to the eleventh carbonization chamber The required amount of movement of the slide base for aligning the leveling device with the carbonization chamber No. 6 by comparing the carbonization chamber pitch size up to (S12) and determining the difference between the two carbonization chamber pitch sizes (S7) Can be determined (S8).

  While the extrusion discharge device is moving from the carbonization chamber of No. 6 to the carbonization chamber of No. 11, by moving the slide base in parallel by the slide drive device according to the required movement amount (S9), the extrusion discharge device is In accordance with the position of the 11th carbonization chamber (S3), the coke is brought into contact with the preparation for extrusion discharge, and at the same time, the leveling device is aligned with the 6th carbonization chamber (S10). Since it is not necessary to adjust the position of the leveling device once the extrusion discharge device is aligned, it is possible to align the leveling beam to the charcoal kiln without requiring an extended operation time.

  When the above procedure is repeated, the kiln operation of all the carbonization chambers across the furnace group is completed, and the recording of all the carbonization chamber pitch dimensions is completed (S6), the recorded total carbonization chamber pitch dimensions are used for the next furnace. It is used for kiln work in all the carbonization chambers across the group (S13).

  According to the leveling device for the coke oven extruder of the present invention, even when the coke oven pitch changes due to the aging of the coke oven or the coke oven pitch changes due to the new installation of the coke oven occur. By mounting all the devices that make up the leveling device on the slide base and moving them all together on the floor where the extruder is placed, there are restrictions due to the positional relationship of the devices that make up the leveling device. Without being received, the leveling device can be aligned with the coal kiln, and the management cost can be reduced by reducing the number of inspection and maintenance points.

  Furthermore, according to the operation method of the leveling device of the coke oven extruder of the present invention, by performing the alignment to the carbonization chamber that is the target of the coal charging operation of the leveling device during the movement of the extruder, It is possible to prevent a decrease in productivity due to a delay in the kiln work.

  Below, the structure of the leveling device of the coke oven extruder according to the present invention will be described with reference to the drawings.

  FIG. 3 is a view schematically showing a leveling device of a coke oven extruder according to the present invention. FIG. 3 (a) is a view showing a longitudinal cross section of the leveling device in the coke oven, and FIG. ) Is a cross-sectional view taken along the line AA in FIG.

  As shown in FIGS. 3A and 3B, the leveling device of the present invention opens and closes the leveling beam 13, the leveling beam receiving roller 14, the leveling beam driving motor 15, and the leveling small lid 16. It is composed of a leveling small lid opening / closing device 17 and a leveling small lid connecting chute 18, and these devices are all mounted on the slide base 2. The slide base 2 has a structure that can be translated in the direction of the furnace group by the bearing 11, and can be translated in the direction of the furnace group in order to align the position with the target carbonization chamber by the slide drive device including the hydraulic cylinder 10. It is said. The charging port 20 of the return charcoal receiving hopper 19 and the discharging port 22 of the return coal processing conveyor 21 are fixed to the extruder 1, and the charging port 20 and the discharging port 22 are extended to the lateral movement range of the slide frame. . Further, the floor 12 on which the leveling device is placed is movable in the furnace group direction by a floor driving device (not shown).

  Next, the operation method of the leveling device of the coke oven extruder according to the present invention will be described based on specific numerical values.

  When the adjacent carbonization chamber pitch dimension is 1400 mm, the 5 kiln pitch dimension of the carbonization chamber is 7000 mm. Therefore, in the conventional extruder, the extrusion discharge device and the leveling device are previously mounted on the floor at an interval of 7000 mm. However, when the pitch of the coking chamber is increased due to the aging of the coke oven, the pitch of the five kilns in the coking chamber is 7000 mm or more, and a new coke oven is constructed in which the pitch size of the adjacent coking chamber is 1500 mm. The 5 kiln pitch dimension of the carbonization chamber is 7500 mm, and when performing the kiln work using the above-described extruder, it is necessary to align the leveling device each time.

  In the present invention, a leveling device composed of a leveling beam, a leveling beam receiving roller, a leveling beam driving motor, a small lid opening / closing device, and a small lid connecting chute is used as a slide frame that can be translated in the furnace group direction. It is mounted and position adjustment in the furnace group direction to the coking chamber to be leveled is possible.

  Regarding the detection of the carbonization chamber pitch dimensions during the work out of the kiln, the carbonization chamber pitch dimensions are measured by calculating the amount of movement of the extruder using a calculation method based on the rotation speed and wheel diameter of the wheel shaft of the extruder. Yes, the amount of movement of the slide frame in the direction of the furnace group can be determined.

  The carbonization chamber pitch dimension measured using the above-described carbonization chamber pitch dimension detection method is, for example, 7000 mm from the first carbonization chamber to the sixth carbonization chamber, and from the sixth carbonization chamber to the eleventh carbonization chamber. Is 7100 mm, while the extrusion discharge device of the extruder is moved from the 6th carbonization chamber to the 11th carbonization chamber position, it is slid to adjust the leveling device to the 6th carbonization chamber position. Move the gantry parallel to the furnace group direction. In this case, the distance between the extrusion discharge device and the leveling device is 7000 mm, which is the carbonization chamber pitch size of the first carbonization chamber that performed the previous leveling operation and the sixth carbonization chamber that performed the extrusion operation. Therefore, during the movement of the extruder, the slide base is moved in parallel by 100 mm, and the distance between the extrusion discharge device and the leveling device is set to 7100 mm which is the carbonization chamber pitch size of the 6th carbonization chamber and the 11th carbonization chamber.

  By carrying out the above parallel movement while the extruder is moving, the extrusion discharge device is aligned with the carbonization chamber No. 11 and the preparation for extrusion discharge is completed. At the same time, the leveling device is aligned with the carbonization chamber No. 6. Will do.

  At this time, extremely strict accuracy is required for the positioning of the leveling device to the carbonization chamber by the parallel movement of the slide frame. When inserting the leveling beam in the length direction of the coke oven, if the insertion distance is 16000 mm, the width of the coking chamber is 450 mm, and the leveling beam width is 300 mm, the leveling beam will not contact the wall of the coking chamber. When moving the slide base, it is necessary to make the variation error of the parallelism 0.4 degrees or less.

  For this reason, as a method for detecting the parallel movement distance of the slide frame, two reference points are provided on the extruder frame with respect to the longitudinal direction of the slide frame, and the distance between the reference point and the slide frame is determined by a laser distance meter or the like. It is detected by an accurate position detection device, and the movement amount and parallelism of the slide frame in the furnace group direction can be detected by synchronizing with them and driving the hydraulic cylinder.

  For example, when the distance between the position detection devices at two reference points is 10000 mm and the distance between the slide frame and the laser distance meter is 600 mm, the measurement accuracy of the position detection device is ± 0.1% F.S. S. If it is about the same degree, the parallelism of the slide frame can be within 0.01 degrees, and the parallel movement with sufficient parallelism becomes possible. Here, “the measurement accuracy is ± 0.1% FS” is the accuracy possessed by the measurement device, and the tolerance in the entire allowable range (FULL SCALE) is ± 0 regardless of the measurement value. Means 1%.

  Using the leveling device of the coke oven extruder of the present invention and the method of operating the same, the kiln was worked out in an aging coke oven.

At the same time, the leveling beam 13 of the leveling device 4 was driven to flatten the upper part of the coal charged into the carbonization chamber 1c.

  After completion of discharging the coke 5 from the carbonization chamber 6c, the extruder 1 was moved so that the extrusion discharge device 3 was aligned with the center position of the carbonization chamber 11c, as shown in FIG. 4 (b). At this time, the inside of the carbonization chamber 6c was empty, and the leveling device 4 was in a state of moving from the carbonization chamber 1c to the carbonization chamber 6c. Here, in the previous kiln work, the amount of movement from the carbonization chamber 1c to the carbonization chamber 6c detected and recorded by the rotary encoder 8 attached to the wheel 7 of the extruder 1 shown in FIG. The required amount of movement of the slide base 2 calculated based on the amount of movement to the carbonization chamber 11c is determined, and the slide base 2 is slid to the carbonization chamber 6c by the hydraulic cylinder 10 while the distance is detected by the laser distance meter 9, and the position is aligned. It was. Thus, by one movement of the extruder 1, it was possible to align the extrusion discharge device 3 with the carbonization chamber 11c and the leveling device 4 with the carbonization chamber 6c.

  As shown in FIG. 4 (c), the coke 5 in the carbonization chamber 11c is discharged by the extrusion discharge device 3, and at the same time, the coal is charged into the carbonization chamber 6c and the upper part of the coal in the carbonization chamber 6c is flattened. Then, the leveling beam 13 of the apparatus 4 was operated.

  By using the leveling device of the coke oven extruder of the present invention and the method for operating the same, it was possible to carry out a smooth kiln operation even in an aged coke oven as described above.

  According to the leveling device for the coke oven extruder of the present invention, even when the coke oven pitch changes due to the aging of the coke oven or the coke oven pitch changes due to the new installation of the coke oven occur. By mounting all the devices that make up the leveling device on the slide base and moving them all together on the floor where the extruder is placed, there are restrictions due to the positional relationship of the devices that make up the leveling device. Without being received, the leveling device can be aligned with the coal kiln, and the management cost can be reduced by reducing the number of inspection and maintenance points.

  Furthermore, according to the operation method of the leveling device of the coke oven extruder of the present invention, by performing the alignment to the carbonization chamber that is the target of the coal charging operation of the leveling device during the movement of the extruder, It is possible to prevent a decrease in productivity due to a delay in the kiln work.
