DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 are views showing an embodiment of the present invention. FIG. 1 is a side view showing a use state of a cleaning apparatus 10 according to the present invention, FIG. 2 is a front view of the cleaning apparatus 10, and FIG. FIG. 2 is a plan view of the cleaning device 10.
[0009]
That is, the cleaning apparatus 10 has a gantry 12 that can be displaced in the left-right direction (the direction orthogonal to FIG. 1, the left-right direction in FIGS. 2 and 3) by the traversing cylinder 11. It is fixed to the base 20 side via a support device that does not.
[0010]
An advancing / retreating cylinder 14 is supported on the gantry 12 so as to be displaceable in the vertical direction (vertical direction in FIG. 1) via a lifting cylinder 13. A cleaning nozzle 16 having two injection ports 16 a is attached via a rotating hydraulic motor 15. The rotation hydraulic motor 15 is for rotating the two nozzles 16a by rotating the cleaning nozzle 16 coaxially with the rod 14a.
[0011]
The cleaning nozzle 16 is connected to a high-pressure water discharge side of a high-pressure water pump 18 fixed on the foundation 20 via a flexible pressure-resistant tube 17.
On the other hand, the refractory 6 is fixed to the surface of the furnace lid body 5 facing the furnace inside (right side of FIG. 1) via the seal plate 1 and the surface of the furnace lid body 5 facing the furnace outside (left side of FIG. 1). A small lid 7 is provided on the upper portion of the metal plate, and a leveling cap 2 is fixed to the furnace lid body 5 via a seal plate 1 so as to communicate with the inside of the furnace when the small lid 7 is opened. Yes. The structure of the leveling cap 2 itself is the same as that of the prior art shown in FIG. 5, but a part of the cover 2b is omitted in FIG.
[0012]
When the entire furnace lid body 5 is cleaned, it is removed from the coke oven (not shown) by a known lifter 8 (see, for example, JP-A-7-126629), and the furnace lid body is cleaned. Although it is moved to the installation position of the apparatus (not shown), the inside of the leveling cap 10 is also cleaned using the cleaning apparatus 10 at that time.
[0013]
The cleaning procedure by the cleaning device 10 will be described. First, the traversing cylinder 11 is driven to adjust the horizontal position of the gantry 12, and the elevation cylinder 13 is driven to adjust the height direction position of the advancing / retreating cylinder 14. The cleaning nozzle 16 provided at the tip of the rod 14a is adjusted so as to face the leveling cap 2. When the cleaning nozzle 16 faces the leveling cap 2, the advancing / retreating cylinder 14 is driven to insert the cleaning nozzle 16 inside the leveling cap 2. At this time, the cleaning nozzle 16 is brought closer to a position slightly larger than the head thickness of the bolt 3.
[0014]
Then, the traverse cylinder 11 and the lifting cylinder 13 are driven again, and the cleaning nozzle 16 is leveled and moved to a position close to the lower left corner of the frame 2a of the mouthpiece 2. The position close to the lower left corner of the frame 2a is the position where the cleaning nozzle 16 starts cleaning, and thereafter, the cleaning is performed along the edge of the frame 2a as shown by the arrow in FIG. The traverse cylinder 11 and the lift cylinder 13 are driven so that the nozzle 16 moves at a predetermined speed.
[0015]
However, when the cleaning nozzle 16 is moved along the edge portion of the frame body 2a, the cleaning nozzle 16 itself is swung at a speed higher than the moving speed by the rotating hydraulic motor 15, and the high pressure water pump 18 is used. High-pressure water is supplied to the washing nozzle 16 and high-pressure water is jetted from the swiveling jet port 16a.
[0016]
Then, since the high-pressure water injected from the injection port 16a moves as shown by the arrow in FIG. 4 while drawing an arc, the deposit 4 such as carbon that has grown around the bolt 3 is scraped by the high-pressure water. It is loosened and removed from the leveling fitting 2.
[0017]
When it is confirmed that the deposit 4 has been removed, the rotary hydraulic motor 15 and the high-pressure water pump 18 are stopped, and the advance / retreat cylinder 14 is driven to disengage the cleaning nozzle 16 from the base 2.
[0018]
In this way, according to the configuration of the present embodiment, the leveling cap is obtained by appropriately remotely operating the traversing cylinder 11, the lifting cylinder 12, the advancing / retreating cylinder 14, the rotating hydraulic motor 15 and the high-pressure water pump 18. It is possible to remove the deposits 4 such as carbon adhering to the surface facing the inside of the furnace 2. Therefore, the work of removing the deposit 4 manually becomes unnecessary, and the removal work can be performed efficiently. In addition, each cylinder and motor can be controlled by a computer, and a sensor for detecting the positional relationship between the cleaning nozzle 16 and the leveling cap 2 is provided in the cleaning nozzle 16, and the output of the sensor is provided. If the cylinders are driven according to a predetermined program, it is possible to automate the removal work of the deposits 4.
[0019]
In the present embodiment, the movement trajectory of the cleaning nozzle 16 is a trajectory along the edge of the frame 2a as shown in FIG. Since the attached matter 4 can be removed almost certainly, it is possible to prevent a problem that the leveler cannot be inserted.
[0020]
Here, in the present embodiment, the high pressure water pump 18 and the pressure hose 17 constitute high pressure water injection means, and the traverse cylinder 11, the lift cylinder 13 and the advance / retreat cylinder 14 constitute injection direction control means. Is done.
[0021]
In the above-described embodiment, the cleaning nozzle 16 is appropriately moved so that the high-pressure water sprayed therefrom is directed to the edge portion of the frame body 2a. However, the present invention is not limited to this. For example, The shape of the injection port 16a of the cleaning nozzle 16 is a shape in which high-pressure water is radially ejected, the cleaning nozzle 16 is leveled and positioned in the center of the mouthpiece 2, and the high-pressure water is radially ejected in that state. You may make it face the edge part of the body 2a.
[0022]
【The invention's effect】
As described above, according to the present invention, the cleaning nozzle inserted from the inside of the furnace body of the furnace lid body removed from the coke oven into the inside of the leveling cap, and the high-pressure water that injects high-pressure water from this cleaning nozzle.
