Definitions

  • the present invention relates to a coke oven door frame cleaning apparatus for cleaning the door frame, more particularly to a cleaning apparatus for cleaning the sealing plate and the inner surface thereof.
  • the prior art cleaner using such cutters and/or scrapers must be accompanied by such mechanism that enables it to expand or contract when inserting or extracting into or from the door mouth of the coke oven chamber so that the cutters and/or scrapers may be pressure-contacted or detached onto or from the door frame surface to be cleaned.
  • the present invention has been made in the light of the above problems, and is directed to the provision of such door frame cleaning apparatus that is capable of complete cleaning of the door frame surface by washing away with high pressure fluid without leaving any deposits of the persistently stuck tary material and that without requiring any special mechanism for pressure-contacting or detaching the cutters/scrapers when inserting or extending the apparatus. Further, since cutters and/or scrapers are not used, no damage to the door frame surface will result. Door frame cleaning apparatus of this type is disclosed in US-A 3892250 whilst apparatus of the former type is disclosed in FR-A-1491439.
  • the present invention provides a coke oven door frame cleaning appatatus characterised by a stationary main frame, a first jet nozzle supporting sub-frame, a second jet nozzle supporting sub-frame, a heat-proof plate, a plurality of fitting rods for supporting by means of supporting members, said first and second jet nozzle supporting sub-frames and said heat proof plate, a high pressure fluid supply pipe mounted on the periphery of said first jet nozzle supporting sub-frame and having a plurality of branch pipes each with a jet nozzle, a high pressure fluid supply pipe mounted on the periphery of second jet nozzle supporting sub-frame and having a plurality of branch pipes each with a plurality of jet nozzles, means mounted on said main stationary frame for moving up and down said first jet nozzle supporting sub-frame, and main supply pipes each for said supply pipe and connecting to a high pressure fluid supply source; said first jet nozzle supporting sub-frame having a plurality of guide rails, said stationary frame having a plurality of guide members each with a guide roller engaging with said
  • a coke oven door frame cleaning apparatus which generally includes a plurality of fitting rods, a vertical stationary main frame 13, a vertical heat-proof plate 18, a first jet nozzle supporting vertical sub-frame 2 and a second jet nozzle supporting vertical sub-frame 3, the two sub-frames having high pressure fluid supply pipes respectively on the entire periphery thereof.
  • the cleaning apparatus is mounted on a carrier 10 which is per se mounted on a pusher machine on the pusher side or a coke guide car on the coke side of the coke oven battery (both not shown), by means of a hanger member 11 and a pair of spring-loaded fitting members 12.
  • the first sub-frame 2 On the main frame 13 are mounted three guide members 21 each having a guide roller 21' and two pairs of stopper members 20.
  • the first sub-frame 2 has three guide rails 2' respectively receiving corresponding guide rollers 21'.
  • On the entire periphery of the first sub-frame 2 is mounted a supply pipe 4 with a plurality of branch pipes 4' for high pressure fluid, while on the entire periphery of the second sub-frame 3 is mounted a supply pipe 5 with a plurality of branch pipes 5' for high pressure fluid.
  • Both the first sub-frame 2 and the second sub-frame 3 are mounted on the fitting rods 1 through respective supporting members 1' as clearly shown in Fig. 3.
  • the vertical heat-proof plate 18 is also mounted on the front end of the fitting rods 1 through respective mounting members 18', and further supported by respective stays 18"connected to the first sub-frame 2.
  • the size of the first sub-frame 2 is larger than that of the second sub-frame 3 so that it may face the sealing surface 7 of the door frame 6, while the second sub-frame 3 may be inserted deeply into the door mouth 16.
  • Both the supply pipes 4 and 5 are connected to respective main pipes 15 and 14 which are further connected to a high pressure fluid supply source (not shown), when the present cleaning apparatus is placed in the door mouth 16.
  • Each branch pipe 4' has a jet nozzle 9 facing the sealing surface 7 of the door frame 6.
  • Each branch pipe 5' of the supply pipe 5 has a plurality of jet nozzles 9 facing the inner surface 8 of the door frame 6.
  • the jet nozzles 9 may be of such bifurcate or other forked form as illustrated in Fig. 4, if desired for a complete cleaning of wide range of coke oven door frame surfaces.
  • main frame 13 is provided with a hydraulic cylinder 19 with its cylinder rod 19' connected to the first sub-frame 2 so that the latter may be moved up and down with the guide rails 2' engaging with the guide rollers 21'.
  • the cleaning apparatus is carried by the carrier 10 which is per se driven by a coke guide car or the pusher machine to the front of the door frame until the stopper members 20 have abutted against the contact faces 22 of the door frame 6.
  • the hydraulic cylinder 19 is driven to move the first sub-frame 2, if necessary to adjust the vertical position when the cleaning apparatus is inserted into the door mouth 16, as shown in Fig. 3.
  • the heat-proof plate 18 and the second sub-frame 3 have been deeply inserted into the door mouth 16 with the branch pipes 5 and thus the jet nozzles 9 facing the inner face 8 of the door frame 6, and the first sub-frame 2 has been placed facing the sealing surface 7 of the door frame 6.
  • high pressure fluid such as high pressure water
  • high pressure fluid is supplied through the main pipes 14 and 15 through the supply pipes 4 and 5 from the supply source to the branch pipes 4' and 5' and jetted through the jet nozzles 9 onto the sealing surface 7 and the inner surface 8 of the door frame 6 so as to wash away the tar and the like persistently stuck on these surfaces without leaving any deposits thereon.
  • high pressure fluid there may be preferably used high pressure water, however high pressure steam and other fluid may also be used.
