Description

  The present invention relates to a small lid provided on an upper portion of a furnace lid that seals an extrusion side of each furnace chamber of a chamber furnace type coke oven, and a high pressure water combined type small lid cleaning device for cleaning the periphery thereof.

  In a furnace-type coke oven, coal carried by a coal charging vehicle is introduced into the furnace chambers from the coal inlets provided at four to five locations on the top of the furnace. Since a valley is formed, a small lid is provided at the top of the extrusion-side furnace lid that seals the furnace chamber, the small lid is opened after the coal is charged, and a coal-equalizing beam is inserted into the furnace chamber through the opening. Then, it is repeatedly moved in the furnace length direction to flatten the upper surface of the coal, and then the small lid is closed to perform dry distillation of the coal.

  During the carbonization of coal, tar and carbon adhere to the small lid as well as the furnace lid. If these are not removed, gas leakage may occur and cause environmental pollution or suction of outside air. The quality of the coke produced. Therefore, as with the furnace lid, a countermeasure for removing the deposits is required for the small lid.

  Therefore, the small lid was cleaned by the small lid cleaning device. That is, the deposits were removed by the high pressure water jet rotary gun around the entire circumference of the small lid sheet surface, gas path and knife edge tip. The high-pressure water injection rotary gun was moved up and down, left and right, and back and forth by a screw shaft mechanism rotated by a hydraulic motor. In addition, a high-pressure water jet rotary gun may be moved by an industrial robot.

  In order to obtain a good cleaning effect using such a high-pressure water injection rotary gun, the high-pressure water injection rotary gun must be accurately moved along the site to be cleaned. In the past, the origin was detected for the small lid by means of contact detection using a contact limit switch.

  In addition to the small lid itself, the periphery of the small lid, that is, the inner surface of the small lid opening (furnace lid side) needs to be cleaned. As a cleaning device for this part, for example, a scraper is scraped off by forcibly pushing out and pulling out a square scraper that matches the inner dimension of the small lid mouth into the small lid mouth by an actuator such as a hydraulic cylinder. It has been proposed (see, for example, Patent Document 1). Further, a cutter that is rotated by a hydraulic motor may be used.

Japanese Utility Model Publication No. 5-81257

  However, since the small lid is cleaned between the kiln unloading process (the process of extruding coal after dry distillation from the furnace chamber), the working conditions are extremely harsh, and a high pressure water injection rotary gun is installed using a screw shaft mechanism. When moved, dust is likely to adhere to and accumulate on the screw part, and the screw part is likely to corrode.For this reason, the high-pressure water jet rotary gun cannot operate smoothly and a predetermined stroke cannot be secured. There was also.

  In origin detection using a contact limit switch, the limit switch is easily damaged due to the influence of high temperature, dust, water, etc., and because it is contact detection, high reliability cannot be obtained. There is a problem in the accuracy of the position corresponding to the cleaning target part of the rotating gun, and a sufficient cleaning effect may not be obtained. The same applies to the case where the high pressure water jet rotary gun is moved by an industrial robot.

  On the other hand, regarding the cleaning of the inner surface of the small lid mouth, the scraping work with a scraper has a depth and sometimes the inner surface of the small lid mouth including the corner portion cannot be thoroughly cleaned. In addition, in the case of using a rotating cutter, there is a problem in the method of moving the cutter in the vertical and horizontal directions, and there are problems in practical use because the cutter breaks frequently and a traffic jam occurs.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a high-pressure water combined type small lid cleaning device that can efficiently clean the small lid and its surroundings without any hesitation.

[Small lid opening and closing machine]
As shown in FIGS. 2 (a) and 2 (b), the small lid opening / closing machine H advances and retreats the unlocking lever 16, the small lid arm pressing mechanism 17, the small lid opening / closing crankshaft rotating device 18, and the like. A carriage 19 is provided, and is disposed on the top of the gantry 11.

  To open the small lid 2, the carriage 19 having four wheels 21 to 24 is advanced by the hydraulic cylinder 25, and the locking roller 28 on the side surface of the small lid 2 is pressed by the unlocking lever 16 by this forward force. The lock 29 of the small lid 2 is removed. Further, at the forward end of the small lid 2, the small lid opening / closing crankshaft 30 is gripped by the hook 31 of the crankshaft rotating device 18 on the small lid opening / closing machine H side, and after releasing the lock 29, the hydraulic cylinder 26 By rotating the crankshaft 30 via the segment gear 32, the small lid 2 can be opened.

  The hook 31 of the crankshaft rotating device 18 is formed in an outwardly open shape so that it can cope with the crankshaft 30 even if there is a misalignment of up to 40 mm on the left and right. A guide hook 33 for absorbing bending force generated in the crankshaft 30 when the crankshaft 30 is rotated is attached to the lower portion of the hook 31, and the crankshaft 30 is at the forward end of the small lid opening / closing machine H. A guide hook 33 is inserted into the lower portion of the shaft to hold the crankshaft 30 so as not to be deformed.

  The small lid arm pressing mechanism 17 and the crankshaft rotating device 18 are swingably supported by a 4-pin parallel arm 34 attached to the front portion of the carriage 19 and, as described above, in the range of 40 mm to the left and right. When the carriage 19 moves forward, it is guided by the crankshaft 30 and the hook 31 and the guide hook 33 on the small lid opening / closing machine H side, and the 4-pin parallel arm 34 swings left and right. The small lid 2 and the small lid opening / closing machine H are aligned.

  On the other hand, for the closing operation of the small lid 2, the hydraulic cylinder 26 rotates the crankshaft 30 via the segment gear 32 to close the small lid 2, and the arm pressing roller 35 on the small lid opening / closing machine H side is moved to the hydraulic cylinder. 25, the small lid 2 is pressed against the small lid opening, and the carriage 19 is moved backward by the hydraulic cylinder 27 in this state.

Further, the small lid 2 is pressed against the surface of the back steering 36 by the hook 31 of the crankshaft rotating device 18 in order to maintain the angle (180 degrees) when opened during cleaning. The opening angle of the small lid 2 can be adjusted by a bolt 37 attached to the surface of the small lid 2.

[Contact vacuum cleaner]
As shown in FIGS. 3A and 3B and FIGS. 4A and 4B, the contact-type cleaner M that cleans the small lid inner surface 3 moves along the small lid inner surface 3. , A rotary cutter mechanism 42 having a rotary cutter (for example, screw cutter) 41 for removing foreign matters such as tar and carbon deposited on the inner surface 3 of the small lid, and advancing while supporting the rotary cutter mechanism 42 A moving carriage 43 that moves backward and up and the alignment means 14 are provided, and are arranged in the center of the gantry 11. Although not shown in the drawings as a contact cleaner, a scraper may be used instead of the above-described rotary cutter 41, and a non-contact cleaner is used instead of such a contact cleaner. In this case, for example, a high pressure water injection rotary gun or the like can be used instead of the rotary cutter 41.

  The rotary cutter mechanism 42 includes movement restriction frames 44 and 45 for restricting the vertical and horizontal movements of the rotary cutter 41 in accordance with the small lid inner surface 3 (see FIG. 4B). The movement restricting frames 44 and 45 are formed in the vertical and horizontal directions, and wheels 46 and 47 provided on the rotary cutter 41 are inserted therein so as to be able to run. The rotary cutter 41 is rotated by a hydraulic motor 48 and moved in the vertical and horizontal directions by hydraulic cylinders 49 and 50. The frame of the rotary cutter mechanism 42 is supported on the moving carriage 43 via the four wheels 51 to 54, and is moved in the left-right direction by the cylinder cylinder 15A. The movable carriage 43 is used for aligning the rotary cutter mechanism 42.

The alignment operation (front / rear, up / down, left / right) of the contact-type vacuum cleaner M by the alignment means 14 will be described below (see FIGS. 3A, 3B, 4A, 4B).
(1) Positioning in the front-rear direction The movable carriage 43 is advanced by the cylinder cylinder 15B, and the forward end stopper 57 is brought into contact with the surface of the belly plate 56 of the furnace lid 1 and stopped at the forward end. The forward end is detected by a limit switch mechanism 58 with a built-in spring.

(2) Positioning in the vertical direction On the movable carriage 43, an elevator carriage 59 for raising and lowering the rotary cutter mechanism 42 is provided. The elevating carriage 59 is supported by four wheels 63 to 66 that are movably inserted into moving frames 61 and 62 provided in the vertical direction on the movable carriage 43, and the elevating stroke of the elevating carriage 59 is increased. The cylinder cylinder 15 </ b> C is connected via a lever mechanism 67 for use. After the moving carriage 43 stops at the forward end, the rotary cutter mechanism 42 is raised by the cylinder cylinder 15C, and the rising end stopper 69 is brought into contact with the lower surface of the lug piece 68 of the furnace lid 1 at the rising end and stopped. The rising end is detected by a limit switch mechanism 70 with a built-in spring.

(3) Positioning in the left-right direction The movement in the left-right direction is performed only by the rotary cutter mechanism 42 with the moving carriage 43 stopped. The rotary cutter mechanism 42 is traversed (moved left or right) by the cylinder cylinder 15A, and the traverse end stopper 72 is brought into contact with the inner side of the side wall 71 of the furnace lid 1 at the traversing end and stopped. The transverse end is detected by a limit switch mechanism 73 with a built-in spring.

  This completes the alignment (alignment) in the three-dimensional direction. At this time, the rotary cutter 41 is at a position on the center line of the small lid (see FIG. 4C). Each of the above-described operations for alignment in the three-dimensional direction is performed by the three cylinder cylinders 15A, 15B, and 15C constituting the alignment means 14, from the initial position to the completion of alignment. The moving distance can be stored as data. This distance data is reflected in the control circuit of the industrial robot 13 of the high-pressure water cleaning apparatus W, and is used as the starting point for starting the operation of the high-pressure water cleaning apparatus W. Thereby, the cleaning with high-pressure water can also be performed efficiently, and the small lid 2 and its surroundings can be cleaned without hesitation.

  By the way, the cleaning range of the inner surface 3 of the small lid opening by the rotary cutter 41 is set to a portion and a bottom surface of up to 2/3 of the height direction of both side walls of the through-opening 3a of the rectangular cross section formed in the furnace lid 1, and the height direction The 1/3 portion and the ceiling portion are excluded from the objects to be cleaned because there is little adhesion of tar and carbon (see FIG. 4C). However, when there are many deposits also in this part, it can also be included in the cleaning range. The rotary cutter 41 includes a radial cutter, a spiral cutter, a screw cutter, and the like in descending order of the cleaning effect, and can be appropriately selected according to the attached matter.

  As described above, the centering of the rotary cutter mechanism 42 is such that the forward end is on the surface of the belly plate 56 of the furnace lid 1, the rising end is on the lower surface of the lug piece 68 of the furnace lid 1, and the transverse end is on the furnace lid 1. This is performed by detecting the arrival at the inside of the side wall 71 by the stoppers 57, 69, 72, that is, for the furnace lid 1. Since the error in the relative position of the furnace lid 1 and the small lid 2 is due to a manufacturing error, the rotating cutter mechanism 42 can be accurately aligned with the inner surface 3 of the small lid opening. After the alignment, the movement of the rotary cutter 41 in the vertical and horizontal directions is restricted by the movement restriction frames 44 and 45, so that the rotary cutter 41 can be made to correspond to the site to be cleaned with high accuracy. Therefore, it is possible to avoid the occurrence of troubles such as damage to the rotary cutter 41 and movement congestion, and the small lid mouth inner surface 3 can be efficiently and efficiently cleaned. Further, as described above, when changing the cleaning range of the small lid inner surface 3 depending on the degree of deposits, the position of stoppers (not shown) provided in the movement restriction frames 44 and 45 is adjusted, The restriction positions of the wheels 46 and 47 may be changed.

[High pressure water cleaner]
As shown in FIGS. 5 and 6 (a) and 6 (b), the high-pressure water cleaning device W for cleaning the entire periphery of the tip of the small lid sheet surface 4, the gas passage 5, and the knife edge 6 is free. A high-pressure water jet rotary gun 12 that is moved and operated by an industrial robot 13 of degree 4 is provided. The high-pressure water injection rotary gun 12 is attached to the tip of the arm 13a of the industrial robot 13, and injects high-pressure water and is moved and operated to ensure an appropriate cleaning width. The high-pressure water injection rotary gun 12 is rotated by a hydraulic motor 81, and the movement is performed in a path set in advance by following the industrial robot 13.

  A plurality (2 to 4) of high-pressure water nozzle tips 12a are attached to the tip of the high-pressure water injection rotary gun 12. By adjusting the attachment angle of the high-pressure water nozzle tips 12a, the location to be cleaned ( The cleaning range (high-pressure water injection range) can be set so as to cover the small lid opening sheet surface 4, the gas passage 5, and the entire circumference of the tip of the knife edge 6.

  As described above, since the starting point of the operation of the contact-type cleaner M obtained by the aligning means 14 is given to the industrial robot 13, the site to be cleaned (the small lid opening sheet surface 4, the gas passage 5). Further, high-pressure water can be sprayed with high precision over the entire circumference of the tip of the knife edge 6, enabling efficient and efficient cleaning, and solving the problems in the prior art. The industrial robot 13 is housed in a sealed casing 82 for dustproof, waterproof and heatproof, and is pressurized to introduce positive pressure into the casing 82 to be sufficiently protected. Yes.

Next, although there are some overlapping effects of the cleaning device of the present embodiment, it will be described in detail below.
(1) Since the high-pressure water injection rotary gun 12 is moved by the industrial robot 13 housed in a sealed casing 82 for dust-proof, waterproof and heat-proof, it is the same as the conventional one using a screw shaft mechanism. Occurrence of troubles due to accumulation of fine dust and corrosion can be avoided, a smooth movement operation can be maintained, and a predetermined stroke can be secured.

(2) The high-pressure water injection rotary gun 12 needs to be accurately moved with respect to the location to be cleaned, but in order to detect the origin of the movement start (as the alignment means 14 of the contact cleaner M). Since the SIRUNAC cylinder 15 (15A, 15B, 15C) is used, it is not affected by dust, water, heat, etc., as in the past using a contact limit switch mechanism, and may be damaged. And high movement accuracy can be stably maintained.

(3) If deposits such as tar and carbon deposit on the inner surface 3 of the small lid mouth, it will not be possible to smoothly insert the coal leveling beam from the through opening 3a. It becomes. Therefore, the cleaning state of the small lid inner surface 3 is particularly important. In the present embodiment, since the rotary cutter 41 is used, the cutting ability is significantly higher than that of a conventional scraper or the like, and a high cleaning effect is obtained.

(4) In the past, there was an example where a rotary cutter was used to clean the inner surface 3 of the small lid, but since a contact limit switch was used as the centering means for the small lid, high accuracy was maintained as described above. In addition to being unable to do so, traffic jams and breakage accidents of the cutter occurred frequently, and a high cleaning effect could not be expected. In the present embodiment, as described above, by adopting the SIRUNAC cylinder 15 (15A, 15B, 15C) for the alignment of the contact-type cleaner M using the rotating cutter, the conventional problems are greatly solved. ing.

(5) Conventionally, there has been an example in which an industrial robot has been used to move the high-pressure water injection rotary gun, but the reliability of the detection accuracy of the origin with the small lid is low, and the gun can be appropriately adapted to the location to be cleaned. The cleaning effect could not be obtained. In the present embodiment, since the mechanical contact type vacuum cleaner M and the high-pressure water cleaning device W are combined, the gun can be made to correspond to the site to be cleaned with high accuracy, and a high cleaning effect can be obtained.

(6) In the cleaning device of the present embodiment, the small lid opening / closing machine H, the contact-type vacuum cleaner M provided with the alignment means 14, and the high-pressure water cleaning device W are used as a system together with other accessory devices. Since the integration is well balanced, a high cleaning effect can be stably maintained as a whole, and the problems of the conventional cleaning device lacking in consistency can be solved.

  It should be noted that the present invention is not limited to the embodiment, and it is free to make design changes and improvements as necessary, as long as it does not depart from the gist of the invention. The alignment means for performing the alignment may be a combination of a potentiometer and a hydraulic cylinder. In addition, the contact type vacuum cleaner may be of any type or configuration as long as it cleans by contacting the inner surface of the small lid. Furthermore, instead of the industrial robot that operates the high-pressure water injection rotary gun, a screw shaft mechanism with a dustproof device that is operated by an actuator such as a hydraulic motor may be used.
