United States Patent 3,448,475 APPARATUS FOR CLEANING THE SEALING SURFACES 0F COKE OVEN DOORS Walter Stanke, Essen, Germany, assiguor, by mesne assignments, to Koppers Company, Inc., Pittsburgh, Pa., a corporation of Delaware Filed June 29, 1967, Ser. No. 650,040 Claims priority, applicatigg sfgrmany, July 26, 1966,
Int. Cl. nzsd 79/00 US. CI. 15-93 6 Claims ABSTRACT OF THE DISCLOSURE The apparatus disclosed includes a support frame on which is mounted guides which direct the movement of rotatable cleaning devices that engage and clean the surfaces of door plug and also the sealing strip of a cokeoven door. In one operation all surfaces of a coke-oven door are cleaned on which deposits usually form.
Background of the invention Summary of the invention The invention represents a further development of this known apparatus and consists in constructing the cleaning means in two parts, in which one part serves for cleaning the sealing strip and the other part serves for cleaning the door plug or its holder and both parts are connected with one another by a universal joint.
According to another characteristic of the invention it is also possible to increase-in steps the diameter of the part for cleaning the sealing strip in such a Way that both the edge of the sealing strip and the recessed inside surface are also treated. Finally, it is recommended that the part for cleaning the door plug and the cleaning tools fastened on this part are constructed in such a way that they can be pressed against the to-be-cleaned surface by means of springs.
Brief description of drawing An embodiment of the apparatus conforming to the invention is illustrated in the drawing, in which the cleaning means are illustrated in section and in perspective.
Detailed description Each cleaning means, indicated as a whole by 1, is guided by two pairs of rollers 2 and 3 in sections 4 and 5 of the transportable supporting frame 6 and is moved in the sections by endless chains not illustrated here. The cleaning means receive their rotary motion by drive motors, which are either flange-mounted directly on them or are arranged stationarily on the supporting frame and are connected with the cleaning means by shafts with universal joints.
The actual working part of each clearing means consists of parts 7 and 8, in which part 8 is fastened on part 7 by a universal joint 20. The periphery of part 7 is provided with scraping edges 9, which can be designed in the form of "ice milling cutters and treat the edge 10 of the sealing strip 11 on the coke-oven door 12. As indicated in broken lines, the diameter of the cleaning part 7 can be increased in steps with formation of an additional tool for cleaning the inside surface 14 of the sealing strip.
Thecleaning part 8, which is rotated with part 7, is provided with a number of scraper-like cleaning tools 15, which remove deposits fom the holder 16 of the door plug 17. These cleaning tools are elastically mounted on part 8 by means of springs 18 so that their position can be adapted to the surface of the holder 16. The cleaning tools 15 are provided with rounded mountings so that staggered brick holders can also be cleaned without damage to the tools or the brick holders.
Finally, a protective shield 19 is provided on the supporting frame 6. This shield surrounds the door plug 17 in the operating position of the cleaning means.
The cleaning apparatus conforming to the invention makes it possible to clean in one operation all surfaces of the coke-oven door on which can form deposits that would impair the sealing of the door on the door jamb. By flexible fastening of the cleaning part 8 with universal joints, furthermore, care is taken that the door plug and its holder are also thoroughly cleaned. This would not be assured in a rigid arrangement. A thorough and automatic cleaning is achieved by suitable selection of the number of revolutions of the cleaning tool.
What is claimed is: 1. In an apparatus for cleaning the sealing surfaces of a coke-oven door, the improvement comprising:
(a) a support frame positionable relative to said cokeoven door;
(b) a plurality of cleaner elements mounted in guide sections on said frame for engaging the surfaces of said door that are to be cleaned, each cleaner element including (i) first and second rotatable cleaner tools that are pivotally interconnected to rotate about separate axes and are driven by a common shaft,
(ii) one said cleaner tool being positionable to clean one respective surface of said door and (iii) the other said cleaner tool being positionable to clean another respective surface of said door; and
(c) means to move said cleaner elements relative to said door as said cleaner tools engage and clean said door surfaces.
2. The structure of claim 1 wherein:
(a) one of said separate cleaner units includes resiliently mounted portions that engage said door.
3. The structure of claim 1 wherein:
(a) each pair of cleaner units includes one unit that is resiliently biased to engage a respective sealing surface of said door; and
(b) a motor operates each pair of cleaner units.
4. The structure of claim 1 wherein:
(a) one cleaner unit of each pair of units is connected to the other unit by means of a universal joint whereby said one unit is movable relative to the other unit and is driven simultaneously and synchronously with the other unit.
5. The structure of claim 1 including:
(a) a shield mounted to said support frame that surrounds the plug portion of said door when said frame and cleaning units are disposed operatively with respect to said door.
6. The structure of claim 1 wherein:
(a) one unit of each pair of cleaner units engages and 3 4 cleans the door sealing strip while the other unit of a pair of units engages and cleans portions of the FOREIGN TE door plug. 910,590 11/1962 Great Bntam.
