Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furnace lid cleaning nozzle apparatus for cleaning tar adhering to a gas path in a furnace lid of a coke oven installed in an ironworks, and more particularly to a furnace having different gas path shapes. The present invention relates to a furnace lid cleaning nozzle device capable of changing a cleaning range during operation to effectively adapt to a plurality of cleaning ranges when lids are mixed, and a cleaning device including the furnace lid cleaning nozzle device.

[0002]

2. Description of the Related Art A gas path for discharging gas generated during coal carbonization is installed in a furnace lid of a coke oven. However, when dust and tar in gas components adhere to the furnace path, the gas path becomes narrow. The furnace pressure increases, and gas leakage occurs. Therefore, every time coke is extracted, deposits such as tar adhering to the gas path of the furnace lid are washed away by the cleaning device.

As a cleaning device for the furnace lid described above,
A radial cutter that cleans the side of the furnace lid to which dry carbon adheres, a knife edge to which sticky tar adheres, and the inside of the lifter that moves up and down along the removed furnace lid gas path Japanese Patent Application Laid-Open No. Sho 59-182886, and Japanese Patent Laid-Open Publication No. Hei 3-3, for example, disclose a device provided with a nozzle gun for injecting high-pressure water from an injection cylinder to clean the periphery.
No. 9391, and a gazette.

[0004]

However, in the above-described conventional cleaning apparatus, the cleaning width by one nozzle gun is limited. Therefore, when furnace lids having different gas path widths are mixed, uncleaned portions are generated. There was a problem of doing.

[0005] Further, if all the furnace lids having different gas path widths are made to correspond with one nozzle gun, high pressure water is sprayed out of the cleaning range in the furnace lid in which the cleaning range is not suitable, so that the knife edge side is not used. In this case, since high-pressure water is injected outside the furnace lid, there is a problem that the high-pressure water is lost. On the other hand, on the refractory side, direct injection is performed on the brick, and the high-temperature brick surface is rapidly cooled.

Therefore, it is conceivable to switch the cleaning range by using a plurality of nozzle guns, for example, two nozzle guns. When two nozzle guns are arranged side by side in the vertical direction of the gas path, they are located at the lower end at the lower end of the gas path. There is a problem that the nozzle gun hinders the cleaning range of the nozzle gun located at the top, and uncleaned portions are generated.

The present invention has been made to solve the above problems, and can cope with a mixture of furnace lids having different gas passage widths without generating an uncleaned portion. It is an object of the present invention to provide a furnace lid cleaning nozzle device capable of switching between various cleaning ranges and efficiently cleaning a gas passage by a simple configuration that does not require the above, and a cleaning device provided with the furnace lid cleaning nozzle device. Aim.

[0008]

In order to achieve the above object, a furnace lid cleaning nozzle device according to the present invention is provided with a plurality of injection ports adapted to a plurality of cleaning areas on a tip surface of one injection cylinder. Or, in addition, each of the plurality of injection cylinders at the tip end surface to form an injection port adapted to one cleaning range,
A plurality of injection ports corresponding to a plurality of cleaning ranges are formed on each of the tip surfaces of the plurality of injection cylinders, the injection ports are switched by a switching valve according to the cleaning range, and at the time of cleaning, the shaft is rotated by a rotation drive unit. At the same time, high-pressure water is injected from the switched injection port. By doing so, it becomes possible to perform cleaning while changing a plurality of ranges during operation with one furnace lid cleaning nozzle device.

Further, the cleaning apparatus of the present invention has the above-described furnace lid cleaning nozzle device of the present invention attached to the above-mentioned furnace lid cleaning nozzle apparatus and the furnace lid, which are lifted up and down in the vertical direction of the furnace lid while being guided by the guide body by the lifting drive unit. A pair of arms each having a removing member for removing solid matter at one end thereof, a fulcrum shaft pivotally supporting the other end of each of the arms, and a driving unit for rotating the fulcrum shaft It was provided with. As described above, by moving the furnace lid cleaning nozzle device and the removing member in the width direction of the furnace lid, the furnace lids having different widths can be efficiently cleaned.

[0015] If two furnace lid cleaning nozzle devices are installed in the vertical direction of the furnace lid, the lower part of the gas path of the furnace lid will allow the lower part of the gas pipe to lower the cleaning range of the upper injector cylinder. However, in the present invention, a plurality of injection cylinders of one furnace lid cleaning nozzle device are arranged in a vertical direction of the furnace lid.

It is a tube. That is, if a plurality of injection cylinders are arranged in the up-down direction of the furnace lid and a plurality of injection ports adapted to a plurality of cleaning ranges are formed on the front end surfaces of the plurality of injection cylinders, the same effect as above can be achieved. And can be adapted to more injection ranges.

Further, the cleaning apparatus of the present invention includes an elevating body that moves up and down in the vertical direction of the furnace lid, and an elevating drive unit provided on a guide body that guides the elevating body to move up and down.

In the above configuration, for example, the lifting drive unit includes a drive sprocket provided at the upper end of the guide body, a driven sprocket provided at the lower end of the guide body, and a chain spanned over the drive sprocket and the driven sprocket. , For example, a motor that rotationally drives the driving sprocket.

The furnace lid cleaning nozzle device and the removing member of the present invention are provided at one end of the arm of the elevating body, and the arm is a pair of two, and the other end of each arm is pivotally supported. Each is pivoted on an axis. Then, the width between the arms is changed by rotating the pivot shaft by the driving unit.

By the way, also in the second embodiment, the hydraulic motor 14 is driven to rotate during injection of the high-pressure water so that the injector 21 or 22 is rotated.
Is rotated, for example, the injection cylinder 2 of the injection body 21
When high-pressure water is being injected from 1A, a part of the water functions as a lubricant.

At this time, if the shaft 22B of the injector 22 not ejected is also rotated in the same manner as the rotation of the injector 21, the lubrication function of the shaft 22 of the injector 22 due to water leakage cannot be obtained. Such a failure may occur. Therefore, in the nozzle device 11 of the second embodiment,

The high-pressure water supply passage 22a is closed by the
Is switched to open, and high-pressure water is injected from the injection ports A of the injection cylinder 21A via the high-pressure water supply passage 21a.

At this time, the hydraulic motor 14 is driven in the direction of the arrow in FIG. 6, and the rotation of the output shaft of the hydraulic motor 14 rotates the gear 31A via the gear 13B and the gear 32A. At this time, since rotational power is transmitted from the one-way clutches 31a and 31b to the shaft portion 21B, the injector 21 rotates. Since the one-way clutches 32a and 32b do not transmit rotational power, the shaft portion 22B does not rotate.

To rotate. At this time, the one-way clutches 32a, 32
b to the shaft portion 22B, so that the injection body 2
2 rotates. Since the one-way clutches 31a and 31b do not transmit rotational power, the shaft 21B does not rotate. By doing so, the nozzle device 11 rotates while jetting high-pressure water, and reliably cleans the cleaning range shown in FIGS. 7A and 7B.

As described above, the nozzle devices 1 and 11 can selectively clean a plurality of ranges by one unit. However, the structure for selectively cleaning a plurality of ranges is as follows.
