Description

  TECHNICAL FIELD The present invention relates to a coke extrusion apparatus for extruding generated coke from a carbonization chamber in a coke oven, and in particular, reducing the extrusion load, reducing damage to the furnace wall (side wall) of the carbonization chamber, and The present invention relates to a coke extrusion device capable of extending the life. In the present invention, unless otherwise specified, the coke oven refers to a chamber type coke oven. The chamber furnace type coke oven has a heat storage chamber at the lower portion of the furnace body, and combustion chambers and carbonization chambers are alternately arranged at the upper portion thereof.

  In the coke oven, when coke (coke lump) produced by carbonizing coal in the carbonization chamber is extruded from the carbonization chamber using an extrusion device, the coke is clogged in the carbonization chamber, resulting in an increase in the extrusion load. As a result, a large force acts on the furnace wall of the carbonization chamber, and the furnace wall may be damaged. When the clogging is severe, the furnace wall is destroyed, or it cannot be pushed out by the extrusion device, and the furnace temperature is lowered, and then the coke is scraped out manually. For this reason, there are problems such as an increase in the repair cost of the furnace wall and a reduction in the production amount due to the shutdown of the furnace.

  On the other hand, the following has been proposed as a technique for reducing the extrusion load and preventing damage to the furnace wall.

  For example, when repairing the bottom brick in the carbonization chamber of the coke oven, the dry powder coke is placed in the carbonization chamber, and the dry powder coke fills the recesses on the surface of the bottom brick and flattens it. A method for reducing the friction between the lump and the furnace bottom has been proposed (see, for example, Patent Document 1).

Further, prior to charging the raw coal to the carbonization chamber, the particulate refractory material (5mm or less) (such as graphite or Si ₃ N ₄₎ leave spread the beveled furnace bottom, lump coke and the oven during coke extrusion A technique has also been proposed in which friction between the bottoms is reduced, and as a result, furnace wall damage is prevented (see, for example, Patent Document 2).

  Patent Document 3 discloses a device for carrying out coke by vibrating a horizontal shovel up and down to collapse coke in the carbonization chamber into a bucket.

In the [Problems to be Solved by the Invention] column, the unpublished prior application of the present applicant will be described, and the application number is described here. That is, Japanese Patent Application No. 2005-377312 (Unpublished Application 1).
JP 59-187082 A JP-A-8-120278 Soviet Union Patent No. 981340

  However, the techniques described in Patent Documents 1 and 2 do not lead to a sufficient push load reduction.

  That is, both of the techniques described in Patent Documents 1 and 2 are intended to reduce the frictional force between the coke lump and the carbonization chamber furnace bottom. The main cause of the increase is not the frictional force between the coke mass and the bottom of the coking chamber, but when the coke mass is extruded using an extrusion device, the coke mass pushed by the ram head of the extrusion device is deformed and collapsed. This is because the frictional force between the coke lump and the carbonization chamber furnace wall is increased by spreading in the horizontal direction perpendicular to the extrusion direction.

  In addition, the technique described in Patent Document 3 does not use the extrusion device targeted by the present application, vibrates the horizontal shovel attached to the bucket up and down, collapses the coke in the carbonization chamber into the bucket, The coke in the furnace is scooped out many times with a bucket, and it takes much time to carry out the coke compared to a coke oven using an extrusion device.

  Therefore, in order to solve the above-mentioned problem, in the non-published application 1, the applicant reduced the extrusion load accurately by applying vibration to the coke mass in the carbonization chamber, thereby reducing the furnace of the carbonization chamber. The coke extrusion method and the coke extrusion apparatus which can reduce the damage of a wall are proposed.

  FIG. 10 is a side view showing an example of a coke extrusion device proposed in the non-published application 1, and FIG. 11 is a perspective view of the coke extrusion device.

  In FIGS. 10 and 11, reference numeral 15 denotes a coke extrusion device shown as an example in the non-published application 1, which includes an extrusion ram 20 including a ram rod 21 and a ram head 22, and an extrusion ram driving device (not shown). At the same time, the pressing surface of the ram head 22 pressed against the coke lump 2 in the carbonizing chamber 1 has three pressing surfaces of an upper pressing surface 22a, an intermediate pressing surface 22b, and a lower pressing surface 22c in the vertical direction. A vibration exciter (vibration motor or hydraulic vibration exciter) 28 for vibrating the intermediate pressing surface (vibration plate) 22b in the pushing direction through the vibration rod 29 is provided. It is attached to the ram rod 21.

  Then, using the coke pushing device 15 configured as described above, the vibrator 28 shakes the intermediate pressing surface (vibrating plate) 22b in the pushing direction to impart vibration to the coke lump 2. By moving the ram head 22 forward, the friction between the coke lump 2 and the furnace wall of the carbonization chamber 1 changes from static friction to dynamic friction, and the coefficient of friction decreases, thereby reducing the extrusion load. As a result, damage to the furnace wall can be suppressed.

  However, in the coke extrusion apparatus shown in FIGS. 10 and 11, if the shaker 28 enters the carbonization chamber 1 under a high temperature condition, the coke extrusion device may be damaged by heat, or in the case of a chamber furnace type coke oven, Considering the fact that the width is as narrow as about 400 mm, the vibration exciter 28 is attached to a portion that does not enter the carbonization chamber 1 behind the ram rod 21 so that vibration is transmitted to the vibration plate 22 b via the vibration rod 29. However, when it is applied to a commonly used coke extrusion apparatus, there are the following problems.

  First, the structure of a commonly used coke extrusion apparatus will be described below.

  There are two types of coke extrusion devices generally used as shown in FIGS. 13 and 14, and the coke extrusion device 51 shown in FIG. 13 is a method in which the ram rod 21 is in a straight line from the beginning. The coke pushing device 52 shown in FIG. 14 has a method in which the rear end of the ram rod 21 is bent, and as the ram rod 21 advances, the bent portion 21b falls in the horizontal direction and is aligned with the horizontal portion 21a. Incidentally, the structure using the straight ram rod shown in FIG. 13 is simpler in structure, but the method using the bent ram rod shown in FIG. 14 is mainstream because it requires less installation space.

  In any type of coke extrusion devices 51 and 52, as shown in FIGS. 13 and 14, the ram 20 is attached to the entire upper surface of the ram rod 21 and the ram head 22 attached to the tip of the ram rod 21. And a ram driving device 24 is installed in the vicinity of the rear of the ram head 22 so as to straddle the ram rod 21, and the rack 23 on the upper surface of the ram rod 21 and the rack by the pinion 24a of the ram driving device 24. The ram 20 is pushed into the carbonization chamber 1 by a pinion type drive mechanism. 13 and 14 is a ram shoe which is attached to the ram rod 21 and moves together to support the ram 20, and 27 is a guide roller for supporting and guiding the ram rod 21 passing therethrough. .

  Accordingly, when the coke pushing device shown in FIGS. 10 and 11 is applied to the coke pushing devices 51 and 52 as described above, when the ram 20 moves forward, the vibration exciter 28 moves to the ram driving device 24. Or, it may collide with the furnace wall 1a of the carbonization chamber 1 to interrupt the extrusion operation or damage the equipment. In order to avoid this, the ram rod 21 may be lengthened and the vibration exciter 28 may be attached at a position where the ram rod 21 does not collide with the ram driving device 24 until the extrusion is finished. Moreover, since the bending ram rod type coke pushing device 52 cannot attach the vibration exciter 28 to the bending portion 21b, the distance between the ram driving device 24 and the vibration exciter 28 must be reduced accordingly. Therefore, in order to attach the vibration exciter 28 to a position where it does not collide with the ram driving device 24 or the like, it is necessary to make the horizontal portion 21a of the ram rod 21 longer, and the bending ram rod method is adopted in the first place. This is due to restrictions on the installation space and the like, and it is difficult to lengthen the ram rod 21.

  As shown in FIGS. 10 and 11, when the vibration exciter 28 is attached to the lower surface of the ram rod 21, the vibration exciter 28 and the guide roller 27 may collide. It will be necessary to change the method. For example, the guide roller in the range in which the vibration exciter 28 moves is changed to a ram shoe type that moves together with the ram rod 21, or the guide roller is not arranged in that range.

  The present invention has been made in view of such circumstances, and when the ram head at the tip of the ram is pressed against the coke mass in the carbonization chamber of the coke oven and the coke mass is pushed out of the carbonization chamber, vibration is applied to the coke mass. Coke extrusion device having an appropriate structure capable of avoiding collision between a vibration exciter for applying vibration to the coke mass and a ram drive device for driving the ram, etc. Is intended to provide.

  In order to solve the above problems, the present invention has the following features.

  Embodiments of the present invention will be described with reference to the drawings. In addition, although the following embodiment demonstrates the case where it applies to the coke extrusion apparatus of a bending ram rod system, the case where it applies to the coke extrusion apparatus of a linear ram rod system is the same.

(First embodiment)
FIG. 1 is a side view for explaining a coke extrusion apparatus according to a first embodiment of the present invention, and FIG. 2 is a plan view thereof.

  As shown in FIGS. 1 and 2, the coke extrusion device 11 according to this embodiment includes a ram 20 having a ram rod 21 and a ram head 22 attached to the tip of the ram rod 21, as shown in FIG. 14. The ram rod 21 has a rack 23 attached to the entire upper surface of the ram rod 21, and a ram driving device 24 is installed in the vicinity of the rear of the ram head 22 so as to straddle the ram rod 21. The ram 20 is pushed into the carbonization chamber 1 by a rack-pinion type drive mechanism by the pinion 24 a of the device 24. 1 is a ram shoe that is attached to the ram rod 21 and moves together to support the ram 20, and 27 is a guide roller for supporting and guiding the ram rod 21 that passes therethrough.

  And in this coke extrusion apparatus 11, the pressing surface of the ram head 22 pressed against the coke lump 2 in the carbonization chamber 1 is divided into three pressing surfaces in the vertical direction, and the intermediate pressing in the pressing surface. The surface 22b serves as a vibration part (vibration plate), and a vibration exciter (vibration motor or hydraulic vibration exciter) 28 for vibrating the vibration plate 22b is provided behind the horizontal part 21a of the ram rod 21. One piece is arranged on both the left and right sides with the ram rod 21 in the vicinity of the end. The vibrator 28 and the vibration plate 22 b are connected via a vibration rod 29. In addition, the vibrator 28 has a mechanism 28a for the left and right vibrators to vibrate in an integrated manner and vibrate in the vibration direction (here, the pushing direction).

  As a result, the vibrators 28 arranged on the left and right sides of the ram rod 21 do not collide with the guide rollers 27 that support and guide the ram rod 21 from below.

  Further, as shown in FIGS. 10 and 11, when the shaker 28 is attached to the lower surface of the ram rod 21, the axes of the shaker 28 and the shaker rod 29 are displaced as shown in FIG. Although it may not be possible to sufficiently transmit the excitation force, as shown in FIGS. 1 and 2, by arranging a pair of left and right vibration generators 28 with the ram rod 21 interposed therebetween, The line connecting the center of gravity of the shaker 28 can be made to coincide with the excitation direction (here, the extrusion method), and the excitation force from the shaker 28 can be accurately transmitted to the excitation plate 22b. it can. Note that the pair of left and right vibrators 28 need to have the same phase of vibration, and therefore are synchronized by electrical control or mechanical means.

  The vibrator 28 is connected to the ram 20 by connecting to the vibration plate 22b via the vibration rod 29, but the connection between the vibration plate 22b and the vibration device 28 is released as necessary. Thus, a connection / separation mechanism is provided for enabling the vibration exciter 28 to be separated from the ram 20. That is, the vibration rod 29 is composed of a front vibration rod 29a connected to the vibration plate 22b and a rear vibration rod 29b connected to the vibration generator 28. The front vibration rod 29a and the rear vibration rod 29b The rod 29b is connected via a connecting portion 30, and the connecting portion 30 connects and separates the front vibration rod 29a and the rear vibration rod 29b, whereby the vibration plate 22b and the vibration exciter 28 are connected. The ram 20 and the vibration exciter 28 can be connected and disconnected by connecting and disconnecting them. In addition, what uses a mechanical fitting apparatus and the thing using an electromagnet should just be employ | adopted for the connection part 30. FIG.

  Further, wheels 40 are attached to the vibration exciter 28 and the rear vibration rod 29 b, and a rail 41 is provided along the ram rod 21. When the front vibration rod 29 a and the rear vibration rod 29 b are connected by the connecting portion 30 and the vibration plate 22 b and the vibration exciter 28 are connected, the vibration exciter 28 is synchronized with the movement of the ram 20. The rail 41 is moved. On the other hand, when the front vibration rod 29a and the rear vibration rod 29b are separated by the connecting portion 30, and the connection between the vibration plate 22b and the vibration generator 28 is released, the vibration generator 28 is separated from the ram 20. It comes to stop. In the above description, the shaker 28 may be self-propelled, but here, the shaker 28 is moved by the power of the ram driving device 24 via the vibration rod 29.

  Thus, when the vibration exciter 28 approaches the ram driving device 24 as the ram 20 advances, the connection between the vibration plate 22b and the vibration exciter 28 is released, and the vibration exciter 28 is separated from the ram 20. By stopping at that position, it is possible to avoid the vibration exciter 28 from colliding with the ram driving device 24.

  In addition, the ram rod 21 is usually a box structure with a hollow inside, but since the vibration exciter 28 is installed on both the left and right sides with the ram rod 21 in between, as shown in FIG. The vibration rod 29 is installed along the left and right outer surfaces of the ram rod 21, and the support mechanism 31 of the excitation rod 29 is also provided on the left and right outer surfaces of the ram rod 21 as shown in FIG. FIG.3 (c) is a figure which shows the positional relationship of the vibration rod 29 and the support mechanism 31 in that case, and the carbonization chamber furnace wall 1a.

  Further, as shown in FIG. 4A, the vibration rod 29 is installed along the left and right outer surfaces of the ram rod 21, but as shown in FIG. A support mechanism 32 for the rod 29 may be provided inside the ram rod 21. FIG. 4C is a diagram showing a positional relationship between the vibration rod 29 and the support mechanism 32 and the coking chamber furnace wall 1a at that time.

Further, in some cases, as shown in FIG. 5 (b), the AA arrow view in FIG. 5 (a) is passed through the inside of the ram rod 21 and the BB arrow view is shown. As shown in FIG. 5 (c), an opening is provided in the ram rod 21 in the vicinity of the connecting portion 30, and the front vibration rod 29a is branched left and right and taken out of the ram rod 21 (vibration rods 29a ₁ , 29a). ₂ ) As shown in FIG. 5 (d), a CC arrow view may be connected to the rear vibration rod 29 b installed along the left and right outer surfaces of the ram rod 21 by the connecting portion 30. By doing in this way, since all the support mechanisms 34 of the front excitation rod 29a can be provided in the inside of the ram rod 21, the influence of the radiant heat from the carbonization chamber 1 with respect to the support mechanism 34 can be minimized. Further, by sending the cooling gas into the ram rod 21, it is possible to suppress the temperature rise of the vibration rod 29 and the support mechanism 34.

  A procedure (operation state) in the case where the coke lump 2 is pushed out from the carbonization chamber 1 by using the coke pushing device 11 configured as described above will be described with reference to FIG.

  (1) First, as shown in FIG. 6 (a), the front vibration rod 29a and the rear vibration rod 29b are connected by the connecting portion 30, and the vibration plate 22b and the vibration exciter 28 are connected. After that, the ram head 22 is advanced toward the carbonization chamber 1.

  (2) Next, as shown in FIG. 6 (b), the ram head 22 is pressed against the coke lump 2 in the carbonizing chamber 1, and the vibration plate 22b is vibrated in the pushing direction by the shaker 28, thereby coke lump. While applying vibration to 2, the ram head 22 is advanced. Thereby, the friction between the coke lump 2 and the coking chamber furnace wall changes from static friction to dynamic friction, and the friction coefficient decreases, thereby reducing the extrusion load. As the ram 20 advances, the bent portion 21b of the ram rod 21 also becomes horizontal and is aligned with the horizontal portion 21b.

  (3) Then, as shown in FIG. 6 (c), when the vibration exciter 28 approaches the ram drive device 24, the front vibration rod 29a and the rear vibration rod 29b are separated by the connecting portion 30 and applied. The connection between the vibration plate 22 b and the shaker 28 is released, and the shaker 28 is separated from the ram 20. As a result, the vibration generator 28 stops before the ram driving device 24, and the application of vibration to the coke block 2 is terminated at this point. By the way, normally, the pushing load is maximized until the ram head 22 moves forward to the center of the carbonizing chamber 1, so that the coke mass is increased until the shaker 28 reaches the ram driving device 24. By applying vibration to the extrusion load, the pushing load can be effectively reduced.

  (4) Then, as shown in FIG. 6 (d), the ram head 22 continues to move forward with the vibrator 28 stopped in front of the ram driving device 24. And if it advances to the position which extrudes the coke lump 2 from the carbonization chamber 1, extrusion will be complete | finished there.

  As described above, the coke extrusion device 11 according to this embodiment vibrates the coke lump 2 while applying vibration to the coke lump 2 by vibrating the vibration plate 22b of the ram head 22 with the vibration exciter 28. Can be separated from the ram 20 to avoid collision with the ram driving device 24, etc., so that it is possible to reduce the extrusion load accurately while preventing the interruption of the extrusion operation and damage to the equipment. it can. As a result, damage to the carbonization chamber furnace wall can be suppressed, operation delay due to clogging can be avoided, and productivity can be increased.

  Further, since the vibration exciter 28 can be separated from the ram 20, maintenance such as repair is easy, and utility communication such as power wiring to the vibration exciter 28 is separated from the ram 20, which is advantageous.

(Second Embodiment)
The basic structure of the coke pushing apparatus according to the second embodiment of the present invention is the same as that of the coke pushing apparatus according to the first embodiment described above, but a ram drive mechanism is provided below the ram rod. The point is different.

  That is, as shown in FIG. 7, in the coke pushing device 12 according to the second embodiment, the ram driving device 24 is installed below the ram rod 21, and the rack (not shown) is the lower surface of the ram rod 21. Is attached.

  As a result, the vibrator 28 can move forward to the vicinity of the coking chamber 1 without colliding with the ram drive device 24, and the coke lump 2 can be vibrated for a longer period.

  A procedure (operation state) in the case where the coke lump 2 is pushed out from the carbonization chamber 1 using the coke pushing device 12 as described above will be described with reference to FIG.

  (1) First, as shown in FIG. 7 (a), the front vibration rod 29a and the rear vibration rod 29b are connected by the connecting portion 30, and the vibration plate 22b and the vibration exciter 28 are connected. After that, the ram head 22 is advanced toward the carbonization chamber 1.

  (2) Next, as shown in FIG. 7 (b), the ram head 22 is pressed against the coke lump 2 in the carbonization chamber 1, and the vibration plate 22 b is vibrated in the pushing direction by the shaker 28, thereby coke lump. While applying vibration to 2, the ram head 22 is advanced. Thereby, the friction between the coke lump 2 and the carbonization chamber furnace wall changes from static friction to dynamic friction, and the friction coefficient decreases, thereby reducing the extrusion load. As the ram 20 advances, the bent portion 21b of the ram rod 21 also becomes horizontal and is aligned with the horizontal portion 21b.

  (3) Then, as shown in FIG. 7 (c), even if the vibrator 28 reaches the ram driving device 24, it does not collide, so it continues to move forward.

  (4) Then, as shown in FIG. 7 (d), when the vibration generator 28 approaches the carbonization chamber 1, the front vibration rod 29 a and the rear vibration rod 29 b are separated by the connecting portion 30 to generate vibration. The connection between the plate 22 b and the shaker 28 is released, and the shaker 28 is separated from the ram 20. The ram head 22 continues to move forward with the shaker 28 stopped in front of the carbonization chamber 1, and when the coke lump 2 is advanced to the position where all the coke lump 2 is pushed out from the carbonization chamber 1, the extrusion ends there.

  As described above, when the coke pushing device 11 according to this embodiment pushes the coke lump 2 while vibrating the vibrating plate 22b of the ram head 22 with the shaker 28, the ram drive mechanism Since it is provided below the ram rod 21, it is possible to avoid the vibration exciter 28 from colliding with the ram driving device 24, and the vibration exciter 28 is separated from the ram 20, and the carbonization chamber of the carbonization chamber 1. Since it has a structure capable of avoiding collision with the furnace wall, it is possible to reduce the extrusion load accurately while preventing interruption of the extrusion operation and equipment damage. As a result, damage to the carbonization chamber furnace wall can be suppressed, operation delay due to clogging can be avoided, and productivity can be increased.

(Third embodiment)
FIG. 8 is a side view for explaining a coke extrusion apparatus according to a third embodiment of the present invention, and FIG. 9 is a sectional view thereof.

  As shown in FIG. 8, the coke extrusion device 13 according to this embodiment includes a ram 20 having a ram rod 21, a ram head 22 attached to the tip of the ram rod 21, and a ram rod 21, as shown in FIG. 14. A ram driving device 24 is installed in the vicinity of the rear of the ram head 22 so as to straddle the ram rod 21, and the rack 23 on the upper surface of the ram rod 21 and the ram driving device 24 are connected to each other. The ram 20 is pushed into the carbonization chamber 1 by a rack-pinion type drive mechanism by the pinion 24a. 8 is a ram shoe which is attached to the ram rod 21 and moves together to support the ram 20, and 27 is a guide roller for supporting and guiding the ram rod 21 passing therethrough.

  And in this coke extrusion apparatus 13, the pressing surface of the ram head 22 pressed against the coke lump 2 in the carbonization chamber 1 is divided into three pressing surfaces in the vertical direction, and the intermediate pressing in that The surface 22b serves as a vibrating portion (vibrating plate), and the vibrator 28 that has been downsized to vibrate the vibrating plate 22b has a horizontal portion of the ram rod 21 having a hollow box structure inside. It is installed inside 21a.

  Accordingly, as shown in FIGS. 9A and 9B, the vibration rod 29 that connects the vibration plate 22 b and the vibration generator 28 and the support mechanism 35 are also installed inside the ram rod 21. . FIG. 9C is a view showing the positional relationship between the vibration rod 29 and the support mechanism 35 and the coking chamber furnace wall 1a at that time.

  As described above, since the shaker 28 is installed inside the ram rod 21, it is possible to avoid the shaker 28 from colliding with the ram driving device 24, the guide roller 27, or the carbonization chamber furnace wall 1a. .

  The line connecting the center of gravity of the vibration rod 29 and the vibration generator 28 can be made to coincide with the vibration direction (here, the pushing direction), and the vibration force from the vibration device 28 can be converted into the vibration plate. 22b can be accurately communicated.

  Further, since the vibration exciter 28 and the vibration rod 29 and the support mechanism 35 are all installed inside the ram rod 21, the influence of the radiant heat from the carbonization chamber 1 on the vibration exciter 28 and the like can be minimized. it can. Further, by sending the cooling gas to the inside of the ram rod 21, it is possible to suppress the temperature rise of the vibration rod 29 and the like.

  Although it is possible to install the vibration exciter 28 at the portion of the ram rod 21 that enters the carbonization chamber 1, the carbonization chamber is formed at the rear end of the horizontal portion 21a of the ram rod 21 in consideration of the influence of radiant heat. It is preferable to install the vibration exciter 28 in a portion that does not enter the inside of 1.

  In the above description, the installation of the vibrator 28 inside the ram rod 21 means that the vibrator 28 is substantially installed inside the ram rod 21, and the range that does not contact the ram driving device 24 and the coking chamber furnace wall 1 a. Thus, the vibration exciter 28 may protrude from the ram rod 21.

  When the ram driving device 24 is installed below the ram rod 21, the ram driving device 24 does not come into contact with the carburetor wall 1a because the vibrator 28 protrudes from the ram rod 21. In the range, the vibration exciter 28 may protrude from the ram rod 21. Furthermore, in addition to this, when the vibration exciter 28 is installed at the rear end portion of the horizontal portion 21 a of the ram rod 21 that does not enter the carbonization chamber 1, the vibration exciter 28 protrudes greatly from the ram rod 21. Also, the ram driving device 24 and the coking chamber furnace wall 1a are not contacted.

  As described above, the coke extrusion device 13 according to this embodiment causes the vibration plate 22b of the ram head 22 to vibrate with the vibration exciter 28 to push out the coke lump 2 while applying vibration to the coke mass 2. Since it is installed inside the ram rod 21 and has a structure that can avoid a collision with the ram driving device 24 and the like, the extrusion load can be reduced accurately while preventing the interruption of the extrusion operation and damage to the equipment. be able to. As a result, damage to the carbonization chamber furnace wall can be suppressed, operation delay due to clogging can be avoided, and productivity can be increased.
