4,186,055 issued January 29, 1980.
During the coking process, carbon and other foreign material is deposited all around the inside of the seal on the coke oven door and along the sides of the refractory plug.
Each time the coke oven door is removed during the coking cycle, the carbon must be removed from both the door seal and the sides of the refractory plug.
Coke oven door cleaners have been provided and are in use but their effectiveness has been somewhat reduced by complicated mechanisms and their inability to clean the metal seal without damaging it, clean the inside corners of the seal, clean seals of various designs without major modifications to the cleaning tools and clean the sides of the refractory plugs.
None of the prior art coke oven door cleaner devices include a structure equivalent to that disclosed in this application and the function of the prior art coke oven door cleaners is not equivalent to the function of the invention disclosed in this application.
An object of the present invention is to provide a coke oven door cleaner that incl~des a reciprocating or oscillating wire rope cleaning assembly which is positioned outside of the cle~ning tool where it eng~es the door seal thereby allowing the cle~ning tool to effectively clean the inside corner areas of the door seal.
According to this invention there is provided a coke oven door cleaner in combination with a coke oven door, a refractory plug mounted upon the door, and a peripheral seal extending outwardly a predetermined ~limen~i~m from the outer edge of the door, said seal having an outer edge eng~hle with a door jamb to form a seal between said door and said door jamb, said door cleaner being operative to clean the peripheral seal and refractory plug of the coke oven door after said door has been removed from a coke oven battery, said coke oven door cleaner comprising a cleaner frame oriented peripherally of the door seal and refractory plug, a plurality of guide rollers supported on said cleaner frame, said guide rollers being conne~ by connecting links to form a peripherally continuous mavable member for movement in relation to the cleaner frame, a plurality of wire rope cleaning assemblies SUp~ ed from the mavable member and engaged with at least one of the refractory plug and seal for clP~ning at least one of the refractory plug and seal, and driving means for driving the movable member in a reciprocatory manner to reciprocate the wire rope cle~ning assemblies in relation to at least one of the seal and refractory block, each ofsaid wire rope cleaning assemblies comprising a plurality of wire rope segm.ont~, each of said wire rope segments comprising a plurality of strands of wire and wherein each of said wire rope segments has a diametral (limpnsion which is at least one fourth of said predetermined ~lim~n~ion by which said peApheral seal extends outwardly from said door frame.
According to another aspect of this invention there is provided in combination with a coke oven door having a peripheral leaf spring seal or a peripheral metal edge seal with refractory plugs mounted on a diaphldgl,l plate for insulation purposes, said diaphragm plate having a thickness ~iimen.sion, a coke oven door cleaner comprising a m~infr~me extending peripherally of the coke oven door in generally parallel relation to the seal and encomp~ ing relation to the refractory plugs to enable the door and cleaner to occupy minimum space, a plurality of movable cle~ning assemblies mounted on the m~infr~me and in cle~ning engagelllent with at least one of the seal and refractory plugs, said mainframe including an endless movable member mounted thereon and conn~ to the ~ ning assemblies for movement in generally concentric parallel relation to at least one of the said seal and refractory plugs, and drive means connected with the movable member for moving the movable member in opposite directions in an oscillatory manner for reciprocating the clP~ning assemblies in relation to at least one of the said seal and refractory plugs, each of said cle~ning assemblies including a plurality of wire rope seglllenl~, each of said wire rope segments comprising a plurality of strands ofwire twisted together, and each of said wire rope segments being supported in spaced relation at one end and having free ends which are engaged with at least one of the said seal and refractory plugs whereby the free ends of the wire ropesegment will flip flop during reverse directions of movement of the clo~ning assemblies and wherein said wire rope segments have a diametral (1imen.~ion which is approximately the same as the thickness ~limension of said diaphragm plate of said door.

-The coke oven door cleaner of this invention isillustrated in association with a conventlonal coke oven door such as that manufactured by Saturn Machine & Welding Co., Inc., of Sturgis, Kentucky and is generally disclosed in U.S. Patent No. 4,186,055 and which includes a door frame 20 with the door seal being designated by numeral 19 and including a leaf spring 18. The refractory plug arrangement forming a part of the_conventional door is designated by reference numeral 21 and, as illustrated in Figs. 1 and 2, the coke oven door cleaner is associated peripherally of the door and the refractory plugs extend through the central portlon of the door cleaner.- With this orientation in mind as illustrated in Flgs. 1 and 2 and also as illustrated in Fig. 3, the coke oven door cleaner includes an outside mainframe component 1 and an inside mainframe component 2 which are concentrically spaced in relation to each other by a plurality of spacers 25 which are spool shaped in order to maintain the inside and outside mainframes 1 and 2 in spaced concentric relation and defining an inwardly facing track arrangement for receiving a plurality of rollers or guide wheels 14 which are journaled on guide wheel axles or roller axles 15 with the axles or pins being interconnected by connecting links 26 which cooperate to form a chain that is in the form of a roller chain that extends peripherally of the mainframe defined by the outside and inside mainframe members 1 and 2. Incorporated into and forming part of the chain is a plurality of tube rails 5 which have support brackets or tool holders 16 attached thereto each of which support a wire rope cleaning assembly 17 which is illustrated in detail in Fig. 3 and includes wire rope cleaning elements projecting therefrom which engage the entire surface area of the leaf spring 18 forming the door seal 19 so that upon movement of the wire rope cleaning assembly 17, the tip ends of the wire rope segments forming the cleaning tool assembly will clean the door seal. As can be seen from figure 3, the wire rope segments are made up of a plurality of wire strands twisted or braided together. The wire rope tool assemblies 17 are reciprocated by a reversible hydraulic drive motor 6 which drives a drive gear 7, roller chain 8 and driven gear 9 having a shaft driven thereby with the shaft being designated by the numeral 10 and journaled in a bearing structure 11 and provided with a pinion gear 12 mounted thereon with the pinion gear 12 being connected to a rack gear 13 which is connected with the tube rails 5, guide wheels 14 and links 26 to oscillate this entire peripheral assembly when the motor 6 is actuated in reversible directions in order to oscillate or reciprocate the wire rope cleaning assembly 17 in relation to the door seal 19.
The coke oven door cleaner illustrated in Figs. 1-3 is capable of cleaning carbon and other foreign matter from the seals and refractories of coke oven doors on both the pusher side and the coke side of a coke oven battery. The door cleaner may be mounted on the coke side door machine or on the pusher machine on the pusher side in a manner well known in this art without any significant difference in its structure or operation on either side of the coke oven battery. As indicated, the door cleaner consists of the vertical mainframe including the outside mainframe 1 and the inside mainframe 2 which are connected by the spool spacers 25. The wire rope cleaning tools 17 are powered by hydraulic motors 6 which drive the pinion gear 12 thus moving the rack gear 13 and thus the wire rope cleaning assemblies back and forth in oscillation.

As illustrated, one of the significant features of the coke oven door cleaner disclosed in this application is the arrangement in which it encompasses the coke oven door thus using less room in the door machine car on the coke side and the pusher machine on the pusher side than other coke oven door cleaners. Also, the structural frame of the present invention is much closer to the cleaning assembly than that of other coke oven door cleaners thereby rendering the coke oven door cleaner of this invention much more stable.
In addition, another feature of the present invention is the manner in which the wire rope cleaning assemblies 17 oscillate with strokes back and forth which will provide a more effective and efficient cleaning process than that of existing inventions in which a continuous movement in one direction is provided for cleaning. In this invention, the wire rope cleaning assemblies change direction and flip flop in the process thus providing the benefit of cleaning the seal and refractory plugs in two directions thereby removing carbon more effectively than a continuous running tool that moves in one direction and tends to trowel the carbon thus packing it even more tightly onto the seal rather than removing it. The wire rope cleaning assembly 17 is also another significant feature of the present invention that solves a major problem inherent in existing coke oven door cleaners. Solid scraper tools used on existing coke oven door cleaners tend to damage delicate seals during the cleaning process unless the alignment of the solid scraper tools with the seal is almost perfect which is seldom obtained. The flexible wire rope cleaning assemblies of this invention specifically preclude damage to the seal even if alignment is not perfect.
The coke oven door of this invention also cleans inside the four corners of the door seal which represents a major improvement over existing coke oven door cleaners.
Further, this invention specifically will clean both square cornered seals and round cornered seals as illustrated in Fig.
The present invention is a coke oven door cleaner including a wire rope cleaning assembly which is oscillated by a mechanical drive structure and which is in engagement with the seal on a coke oven door to clean the seal as well as the side of the refractory plugs provided on coke oven doors. The cleaner includes a mainframe with guide rollers mounted therein with the guide rollers supporting a carriage that supports the wire rope cleaning assemblies which engage the seal and refractory plugs on the coke oven door. The cleaner can be used with various types of coke oven doors having various types of seals associated therewith.

As can be seen from figure 3, the wire rope segments are made up of a plurality of wire strands twisted or braided together. The wire rope tool assemblies 17 are reciprocated by a reversible hydraulic drive motor 6 which drives a drive gear 7, roller chain 8 and driven gear 9 having a shaft driven thereby with the shaft being designated by the numeral 10 and journaled in a bearing structure 11 and provided with a pinion gear 12 mounted thereon with the pinion gear 12 being connected to a rack gear 13 which is connected with the tube rails 5, guide wheels 14 and links 26 to oscillate this entire peripheral assembly when the motor 6 is actuated in reversible directions in order to oscillate or reciprocate the wire rope cleaning assembly 17 in relation to the door seal 19.

As illustrated, one of the significant features of the coke oven door cleaner disclosed in this application is the arrangement in which it encompasses the coke oven door thus using less room in the door machine car on the coke side and the pusher machine on the pusher side than other coke oven door cleaners. Also, the structural frame of the present invention is much closer to the cleaning assembly than that of other coke oven door cleaners thereby rendering the coke oven door cleaner of this invention much more stable.
In addition, another feature of the present invention is the manner in which the wire rope cleaning assemblies 17 oscillate with strokes back and forth which will provide a more effective and efficient cleaning process than that of existing inventions in which a continuous movement in one direction is provided for cleaning. In this invention, the wire rope cleaning assemblies change direction and flip flop in the process thus providing the benefit of cleaning the seal and refractory plugs in two directions thereby removing carbon more effectively than a continuous running tool that moves in one direction and tends to trowel the carbon thus packing it even more tightly onto the seal rather than removing it. The wire rope cleaning assembly 17 is also another significant feature of the present invention that solves a major problem inherent in existing coke oven door cleaners. Solid scraper tools used on existing coke oven door cleaners tend to damage delicate seals during the cleaning process unless the alignment of the solid scraper tools with the seal is almost perfect which is seldom obtained. The flexible wire rope cleaning assemblies of this invention specifically preclude damage to the seal even if alignment is not perfect.
The coke oven door of this invention also cleans inside the four corners of the door seal which represents a major improvement over existing coke oven door cleaners.
Further, this invention specifically will clean both square cornered seals and round cornered seals as illustrated in Fig.
2 and also as illustrated in Fig. 4. Further, the door cleaning assembly is constructed to clean door seals of various designs as demonstrated at Fig. 5 so that newer and different coke oven doors can be installed in a coke oven battery and even a mixture of coke oven doors can be installed without any requirement to change coke oven door cleaners since the present invention will conform to door seals of different shapes and designs.
In operating the coke oven door cleaner of this invention, the existing door extractor which is mounted on the door and/or pusher machine will remove a door from the coke 1 3331 b4 oven jamb in a conventional manner and move it to a position inside the machine and swing the door 90 making the center line of the door parallel with the center line of the coke oven door cleaner as illustrated in Figs. 1 and 2 and generally inside the inside mainframe 2 and the outside mainframe 1 as shown in Figs. 1 and 2. The door extractor will place the door into cleaning position making contact with a leveler shoe 27 which forces the limit switch cam 29 in a downward motion contacting the limit switch 28 thus actuating worm gear actuator 30 sending the door cleaner mainframe constituted by inside and outside mainframes in a downward position until contacting the limit switch 28 thus stopping the door cleaner mainframes 1 and 2 at an elevation aligning the wire rope cleaning assemblies 17 with the seal 19. Here, the door and cleaning assemblies have made contact and the door cleaner is ready to commence the cleaning cycle. An operator will start the hydraulic motor 6 which will oscillate vertically back and forth putting the tube rails 5 in the same motion and transferring that motion into roller and wire rope cleaning assembly 17 which are in contact with the door seal thus removing tar, carbon and other foreign matter from the door seal. The guide wheels 14 are in contact with the outer frame 1 and the inner frame 2 causing the tool holder 16 to maintain a positive radius around the corners of the mainframes. As an option to this arrangement, the tool holder and wire rope cleaning assembly 17 can be retained with a positive radius by the use of cam rollers 39 which serve to decrease the extension of the tool holder 16 thereby pulling the wire rope cleaning assembly 17 back into the round or square corner of the door seal as may be required to maintain the true line of the radius at the corner. After the cleaning process has been completed, the door extractor will remove the door from the door cleaner and place the clean door into sealed position on the door jamb in a manner well known.
Figures 3 and 5 illustrate the top and inside heat shield with the inside heat shield being designated by reference numeral 3 which is located adjacent the refractory and the top heat shield is designated by the numeral 4 and forms a closure between the mainframes 1 and 2. This construction protects the mechanism including the drive pinion gear, the rack gear, guide wheels connecting links and reciprocating tube rail 5 from heat from the refractory plugs 21 which are cleaned by the refractory wire rope cleaning assemblies 22 which are connected to tube rails 5. Figure 5 illustrates an arrangement in which the cleaning assembly is associated with a different type of door including a different door frame 24 and a different seal 23 in the form of a straight edge. Fig. 5 also illustrates the refractory plug cleaner 22 and it is pointed out that the cleaner 22 is utilized in the ~ 333 1 64 structure of Fig. 3 with it being associated with the tube rails 5 in the same manner for movement therewith.
Figures 1 and 2 illustrate the association of the coke oven door cleaner with the door machine car structure 31 which includes the door cleaner leveler assembly bracket 32 and a spring 33 associated with the leveler shoe 27 and a bracket 35 at the opposite end of the door cleaner provided with a pin 35, a vertical guide 36, a vertical guide retainer 37 and a stabilizer bar 38 which cooperate to support the coke oven door cleaner from the door machine 31.
Also, as illustrated in Fig. 4, when cam rollers 39 are provided to follow the inside and outside mainframes, a carriage 40 will be provided to support the cam rollers in proper position with the carriage forming a support for the seal cleaner assembly 17 so that it will move around in round cornered seals or squared cornered seals for effectively cleaning the corners of the seal.
It will be appreciated that the embodiments above described are ones in which:
(a) the cleaner is adapted to clean coke oven doors having seals of various designs;
ones in which:
(b) the cleaning tool is oriented so that cam rollers will effectively retain the cleaning tool in engagement with the corners of the door seals for efficient cleaning thereof; and, 1 3~3i 64 ones in which:

The foregoing is considered as illustrative only of the principles of the invention. Further since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and, accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
