Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning the inner surface of a furnace lid leveling opening provided in a cleaning apparatus for a leveling opening small lid provided in a coke extruder of a coke oven.

[0002]

2. Description of the Related Art Conventionally, a leveling mouth cleaning device has been developed in which a spiral cutter is inserted into the leveling mouth, and the attachments on the upper and lower surfaces and both right and left sides of the leveling mouth are cleaned by cutting with a spiral cutter. (Japanese Patent Laid-Open No. 4-50291)
issue).

[0003] In the case of such a spiral cutter, since the cutter has a cylindrical shape, attachments remain at the corners between the upper and lower surfaces and the left and right side surfaces, and it is difficult to sufficiently clean the inner surface to the corners. Not only that, it is also difficult to discharge the adhering matter outside the leveling mouth. Further, since the left and right side surfaces cannot be cleaned at the same time, the spiral cutter moves along the inner surface in a direction perpendicular to the front-rear direction of the leveling opening, so that there is a problem that a long time is required for cleaning.

[0004]

SUMMARY OF THE INVENTION According to the present invention, not only can a cleaning device for a leveling mouth small lid be used to clean the attachments at the corners between the upper and lower surfaces of the leveling mouth and the left and right side surfaces,
It is an object of the present invention to be able to clean both left and right side surfaces simultaneously, to be able to scrape in the front and rear direction, and to perform cleaning in a short time.

[0005]

In order to achieve the above-mentioned object, the present invention provides a machine frame on a coke extruder, and in a leveling mouth small lid cleaning device provided on the machine frame, the machine frame reciprocates in the front-rear direction. A trolley is provided, and two arms that can enter and exit the leveling mouth of the trolley are pivotally supported by a horizontal horizontal pin and an upright pin so as to be vertically rotatable and horizontally openable and closable, and are leveled at the tip of each arm. It is constituted by a coke oven lid leveling mouth inner surface cleaning device provided with an mouth scraper.

[0006]

According to the present invention, after the machine frame 3 is aligned with the leveling port 13, the forward and backward reciprocating trolley 12 is advanced and the two arms 1
4 and 14 are scrapers 15 and 15 at the tip in leveling opening 13.
Is closed (from the solid line position in FIG. 6 to the virtual line position in FIG. 6).
enter in.

In this state, the two arms 14 and 14 are rotated upwardly about the horizontal pin 38 in the horizontal direction and pressed against the upper surface 13 ′ in the leveling opening 13, and outwardly around the upright pins 40 and 40. By turning, the arms 14, 14 and the scrapers 15, 15 can be opened outward, and the scrapers 15, 15 can be pressed against the left and right side surfaces 13 ", 13" in the leveling opening 13. In this state, the carriage 12 is reciprocated in the front-rear direction to scrape off the attachments on the upper surface 13 'and the left and right side surfaces 13 ", 13". Is pressed against the lower surface 13 ′ and the left and right side surfaces 13 ″, 13 ″ in the leveling opening 13, and is reciprocated in the front-rear direction, so that the fall attachment and the lower surface 13 ′ and the left and right both side surfaces 13 ″, 13 ″ are attached. And can be scraped out of the leveling opening 13.

The upper and lower surfaces 13 ', 13' inside the leveling opening 13
The attachments at the corners of the boundary between the left and right sides 13 ", 13" are the upper and lower surfaces 13 ', 1' by the scrapers 15, 15.
3 'and the left and right side surfaces 13 ", 13" are peeled off with the peeling off of the attached matter, and can be scraped out of the leveling opening 13.
Thereafter, the carriage 12 is retracted so that the original position (FIG. 1 and FIG.
(Solid line position).
