Definitions

  • the invention relates to a device for cleaning the sealing surfaces on leveling doors and door frames of horizontal chamber coking ovens for use on the oven printing machine.
  • the invention has for its object to provide a device for cleaning the sealing surfaces on leveling doors and door frames, which is suitable to clean the sealing surfaces automatically thoroughly and quickly, which can be installed on the printing press without increasing their usual overall length and a second Dozer opener must be installed, and which does not lead to an increase in the time of an oven game by their operation.
  • a cleaning device which has a movable against the leveling door and back approximately U-shaped sheet steel housing, which includes the leveling door frame with its side walls, that in the area of the side walls a guide track is provided, which in a first section parallel to Bulldozer door frame in approximately the same length as this and in a subsequent second section parallel to the side sealing strips of the bulldozer door open at the top also run in approximately the same length and that a carriage can be moved in the guideways, which on the sealing surfaces on the bulldozer door frame and on Leveling door bearing directed liquid nozzles, which via flexible lines, such as Pressure hoses are connected to a suitable high pressure liquid source.
  • the liquid nozzles are advantageous to divide the liquid nozzles into two groups and to connect them to two feed lines which can be acted upon independently of one another, the nozzles for cleaning the sealing surfaces of the leveling door and the door frame running in the direction of travel of the wagon to one of the supply lines and the liquid nozzles: for cleaning the crosswise to the Flä lying in the direction of travel the leveling door and door frame can be connected to the other supply line.
  • the targeted application of the two groups of nozzles is expediently effected by remote-controlled valves.
  • the two groups of liquid nozzles are controlled so that all nozzles are switched on at the start of the movement for cleaning the transverse sealing surface and then when the leveling opening is passed over, the nozzles in the area of the opening are switched off and only the outer ones Nozzles for cleaning the sealing surfaces of the leveling door frame running in the direction of travel are switched on. This prevents liquid from being sprayed into the furnace chamber.
  • the outflowing liquid is collected in the U-shaped sheet steel housing and, together with the coal that escapes during the leveling, is passed on to the leveling coal bunker on the machine.
  • the two groups of nozzles are expediently controlled as when driving over the door frame in order to spray only the sealing surfaces to be cleaned.
  • the guideways in each case from a double rail, the carriage being movably guided on each side by means of rollers between the double rails.
  • a pressure cylinder operated working cylinder which has an angle linkage and two compensating cylinders, e.g. a gas pressure spring to which the wagon is connected.
  • Other drives such as a motor drive, can also be used to move the car.
  • the U-shaped backwards sloping floor below the Planiertürrahmens right up to the end door wall including Lie g introduce steel housing with a.
  • a leveling opening 1 of a coke oven chamber 2 is illustrated in a vertical section.
  • the leveling opening 1 is delimited on the outside by a frame 3, the end face of which forms the sealing surface 4 for the corresponding sealing surface 5 on the leveling door 6.
  • Fig. 1 shows the leveling door 6 in the open position. It is mounted on its rear side via a central intermediate piece 7 on an approximately U-shaped bracket 8, which is firmly connected to the frame 3 of the leveling opening on one leg via an articulated connection 9. On the other leg of the U-shaped bracket 8, a double bracket 8a is pivotally attached, in which a hook 10 of a door opener, not shown, can engage. The door opener also serves to hold the leveling door 6 in the open position, as illustrated in FIG. 1.
  • the cleaning device includes an approximately U-shaped sheet steel housing 11, which is open at the front and top and can be moved against the leveling opening 1 and back with the aid of a guide, not shown.
  • the cleaning device is installed on the furnace printing machines and can be moved in front of the coking chambers.
  • the sheet steel housing 11 assumes the position shown in FIGS. 1 and 2.
  • the bottom 12 of the sheet steel housing 11 begins below the horizontal sealing surface of the frame 3 and runs backwards with an initially weak and in the last section stronger inclination to the rear end.
  • the width of the base plate 12 and thus the U-shaped steel plate housing 11 is larger than the width of the leveling door frame 3, as the illustration in FIG. 2 shows.
  • a guide track 13, 13a formed from double rails is attached to the outside of each side wall.
  • Each guideway consists of a first section that runs in the vicinity and parallel to the sealing plane of the leveling door frame 3 and extends over the entire height of the leveling door frame 3, and a subsequent second section that is close and parallel to the sealing strips of FIG leveling door 6 opened upwards also runs in approximately the same length as this.
  • a slot 14 or 14a is contained in the side walls of the U-shaped sheet steel housing 11.
  • the guideways serve to guide a carriage 15 located in the interior of the sheet steel housing and penetrating the slots 14, 14a on opposite end sides with a pin 16, 16a, a roller 17, 17a being rotatably mounted on each pin, by means of which the carriage 15 is guided back and forth between the double rails 13, 13a.
  • the carriage 15 is essentially formed from one Pipe piece 18 in the form of a U, the pins 16 and 16a being fastened to the outer sides of the legs.
  • the ends of the pipe section 18 are closed and each equipped with at least one liquid nozzle 19, the center distance of which corresponds approximately to the center distance of the vertical sealing strips of the leveling door frame 3.
  • a straight pipe section 20 runs between the legs of the pipe section 18 and is fixedly connected to the U-pipe section 18 by webs 21.
  • further liquid nozzles 22 are spaced apart along the entire length.
  • the pipe section 18 and the pipe section 20 are connected to a high-pressure liquid source, not shown, via a remote-controllable valve 25 or 26. In this way, the liquid nozzles 19, on the one hand, and the liquid nozzles 22, on the other hand, can be connected to the liquid source independently of one another and thus act as spray nozzles.
  • a pressure medium-operated working cylinder 27 which is pivotably mounted on a bracket 29 about a horizontal axis 28, serves as the drive for the back and forth movement of the carriage 15.
  • the piston rod of the working cylinder 27 engages with a fork head 30 in an articulated manner on a lever 31 which is connected to a shaft 32 in the middle in a rotationally fixed manner.
  • the shaft 32 is mounted in suitable bearings on the side walls of the sheet steel housing 11, the ends of which protrude from the bearings.
  • the cylinder of a gas pressure spring (33, 33a) known per se is placed on each end with an eye 34, 34a and is connected in a rotationally fixed manner to the shaft 32.
  • the free end of the piston rods 35, 35a of the gas pressure springs 33, 33a is articulated to the respective pin 16 or 16a of the carriage 15.
  • the shaft 32 guides one Turn clockwise.
  • the gas pressure springs 33, 33a are pivoted in the same direction, the piston rods 35, 35a of the gas pressure springs 33, 33a being extended simultaneously with the pivoting movement under the action of the enclosed pressure medium, and thereby the carriage 15 along the guideways from the lower to the upper End position is moved.
  • the carriage 15 is moved back into the starting position, the pressure medium enclosed in the gas pressure springs 33, 33a being compressed.
  • the cleaning of the sealing surfaces of the leveling door frame 3 and the leveling door 6 is effected during the movement of the carriage 15 between the two end positions.
  • the liquid nozzles are controlled so that the inner nozzles 22 are only switched on when the sealing surfaces of the leveling door frame 3 and the leveling door 6 running transversely to the direction of travel of the carriage 15 lie in the area of action of the inner nozzles 22.
  • the outflowing liquid, together with the dissolved deposits, passes through the base plate 12 of the steel plate housing 11 to the bunker for the absorption of the coal which is obtained during the leveling process.
