Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-lid cleaning apparatus for removing tar and carbon adhering to a small lid of a furnace lid for a coke oven furnace.

[0002]

2. Description of the Related Art A large amount of coal gas is generated when coal charged in a coke oven is carbonized to produce coke. This coal gas contains methane, ethane, and tars, leaks from the seal portion of the furnace lid, is cooled, and adheres as carbon and tar around the seal portion. A flat lid for flattening the upper surface when coal is charged is installed in the furnace lid on the side of the extruder. Coal gas and tar leak out from this seal portion and solidify and adhere. If this is left as it is, unevenness will occur in the seal portion of the small lid, and further gas leakage will occur. In some cases, opening and closing of the small lid may become impossible.

For this reason, conventionally, the removal treatment has been mainly performed by hand using a scraper. In recent years, however, a method of installing a removal device at a kiln position immediately before extrusion of an extruder is generally used for this removal treatment. And also
As disclosed in Japanese Utility Model Publication No. Sho 56-48758, a method has been proposed in which a part is incorporated into a furnace cover cleaner.

[0004]

However, the removal process by hand is a work under high heat and is performed from a moving extruder, so that special consideration is required for safety measures. In addition, a method of installing a cleaning device in front of the kiln immediately before extrusion (usually a kiln 5 gates before the extrusion kiln)
However, it is difficult to match the core between the pushing position and the cleaning position of the small lid, and the use of high-pressure water is restricted because the furnace lid and the small lid are directly installed on the furnace body. Further, in the proposal to be incorporated in the furnace lid cleaning device, there is a problem that the inner surface of the small lid opening (leveling opening) can be cleaned, but the seal portion cannot be cleaned.

[0005]

According to the present invention, a small lid opening / closing device and a high pressure water cleaner for cleaning a small lid (rear surface) are arranged above a door lifter (furnace lid removal machine), and a small lid is installed in the furnace lid cleaning device. An object of the present invention is to solve the above problem by disposing a vacuum cleaner for the inner surface of the lid and cleaning the furnace lid at the furnace lid cleaning position and completely cleaning around the small lid at the same time.

[0006]

According to the present invention, the door lifter removes the door from the coke oven body and moves (revolves) to the retracted end of the coke oven body. By arranging a small lid opening / closing device and a small lid opening and a high-pressure water cleaner for cleaning the small lid back surface opened by the small lid opening / closing device, the inside of the small lid opening, the small lid opening and the small lid back surface are simultaneously cleaned with the door cleaning. Cleaning can be performed.

[0007]

An embodiment will be described below with reference to the drawings.

FIG. 1 is a side view showing an embodiment of the present invention, in which a two-stage mounting base 3 is provided on the top of a lifter holder 2 supporting a door lifter 1, and a small lid is opened and closed on the upper stage of the mounting base 3. The machine 4 is installed, and a high-pressure water cleaner 5 for cleaning the back surface of the small lid opening 23 and the small lid 24 is installed at the lower stage. The high-pressure water cleaner 5 has a plurality of vertically arranged injection nozzles opposed to the small lid opening 23 and the small lid 24 opened by the small lid opening and closing machine 4.
It has a nozzle head 5b provided with 5a at its tip, is supported by a vertical vibration mechanism, and is installed so as to be able to move laterally in the opening direction of the small lid 24.

An inner surface cleaner 8 for cleaning the inner surface of the small lid opening is attached to a furnace cover cleaner 7 which is detached from the furnace body by the door lifter 1 and is installed so as to be opposed to the coke oven door 6 at a further retracted position. . The inner surface cleaner 8 is mounted with a mounting fulcrum 12 at a position behind a frame of the furnace lid cleaner 7 incorporating a side cleaner 10 moving up and down in the guide rail 9 and a bottom cleaner 11 for cleaning the bottom.
A guide frame 13 that pivots and falls toward the coke oven door 6 side based on 12; a truck 14 that fits in the guide frame 13 so as to be able to move forward and backward; It comprises a small lid opening inner surface cleaning cutter mechanism 17 which moves up and down in the front frame 16 of the horizontal moving table 15. 18 is the guide frame 13
, A cylinder 19 for moving the carriage 14 back and forth, a cylinder 20 for moving the horizontal moving table 15, and a cylinder 21 for moving the cutter mechanism 17 for cleaning the inner surface of the small lid opening.

In the apparatus having the above structure, the small lid 24 is opened (180 °) by the small lid opening / closing device 4 at a position where the door 6 is detached from the furnace body and opposed to the furnace lid cleaner 7, and the high pressure is applied. While moving the water cleaner 5 laterally, the front of the small lid 24 and the small lid opening 23 is cleaned by high-pressure water injection from the injection nozzle 5a, and at the same time, the guide frame 13 is swung upward to clean the inner surface of the small lid opening. 17 is made to face the back side of the small lid opening 23, the carriage 14 advances into the small lid opening 23, the horizontal movement of the movable base 15, and the combination operation by the vertical movement of the cutter mechanism 17 for cleaning the inside of the small lid opening. Then, the inner surface of the small lid opening 23 is cleaned.

The side cleaner 10 of the furnace cover cleaner 7
When is operated, the cutter mechanism 17 for cleaning the inner surface of the small lid opening is retracted and swiveled down to retract to the temporary line position in the figure so that the vertical movement of the side cleaner 10 is not hindered.

[0012]

As described above, according to the present invention, the cleaning of the furnace lid can be performed simultaneously with the cleaning of the furnace lid at the cleaning position of the furnace lid. There is no inconsistency in the cores, and high-pressure water can be used without any limitation for cleaning the front of the small lid opening. This provides an effect that cleaning around the small lid can be performed more reliably and safely.
