Abstract

A door cleaner is capable of automatically scraping a door side, knife edge and recessed inside surface to remove tar and the like adhered thereto. The cleaner can remove both viscous material at the knife edge and recessed inside surface of the door and dried and solid material at the door side close to the coking chamber. Jet nozzles are arranged on scraper devices for cleaning the knife edge and the recessed inside areas to completely scrape and further wash away the viscous tars adhered thereto.

Claims

1. A cleaner for a coke oven door having a body with side walls, a sealing plate extending from the body having a recessed surface adjacent the side walls and a sealing blade connected to the sealing plate, the cleaner comprising:

a vertical support frame for receiving the coke oven door having a pair of elongated guide channels adapted to receive the coke oven door body therebetween,

a pair of carriers mounted on said vertical support frame and engaged with each of said guide channels respectively for movement along the length of said guide channels;

hydraulic drive means connected to said vertical support frame and to said carriers for propelling said carriers along said guide channels;

radial cutting means connected to said carriers, on the side of said carriers adapted to face the side walls of the coke oven door body, said radial cutting means including at least one radial cutter rotatably mounted to each of said carriers on a substantially horizontal axis, said carriers and radial cutter means adapted to engage the side walls of the coke oven door body to scrape dried and hardened material therefrom;

a scraper pivotably mounted to each of said carriers adapted to bear against and scrape the recessed surface of the sealing plate; and

a jet nozzle block connected adjacent an end of each of said scrapers adapted to be brought nearest to the recessed surface of the sealing plate, said jet nozzle blocks each having three orifices adapted to respectively face the sealing blade, the recessed surface of the sealing plate, and a portion of the side walls of the coke oven door body adjacent the recessed surface of the sealing plate; and

high-pressured fluid source means connected to said jet nozzle block for supplying high pressure fluid to said jet nozzle blocks and through said orifices to cleanse the sealing blade, the sealing plates and the portion of the side wall of viscous material deposited thereon.

2. A cleaner according to claim 1, including a pair of said radial cutting means and a pair of said scrapers mounted to each of said carriers.

3. A cleaner according to claim 1, wherein the side walls of the body of the coke oven door are recessed inwardly toward each other adjacent the sealing plate, one of said orifices of each of said jet nozzle blocks directed toward the recesses of the side walls.
