Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a coke oven door frame cleaner.

Conventional coke oven door frame cleaners have a large number of cleaner cutters that clean the inner surface of the door frame and the seat surface, so the adhesion between all the cutters and the cleaning surface is poor, making it difficult to remove deposits from all over the door frame. This invention solves the above-mentioned problem, and provides a coke oven door that can ensure close contact between the cleaning surface of the door frame and the cutter, and can evenly clean the entire door frame. The purpose is to provide a frame cleaner.

That is, the present invention provides a coke oven lid frame cleaning device, in which a vacuum cleaner frame that moves up and down by a cylinder mechanism with an operating stroke smaller than the height of the door frame has an inner surface of the door frame at least at intervals of the vertical movement stroke of the vacuum cleaner frame. The subject matter is a coke oven door frame cleaner provided with a scraper having a cleaner cutter and a sheet surface cleaner cutter, respectively.

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

In FIGS. 1 and 2, reference numeral 1 denotes a rotatable lid removing machine, and a downward cylinder mechanism 2 is installed along the vertical direction on the upper part of the lid removing surface of the lid removing machine 1, which is different from the lid removing surface. Guide frames 3 having a C-shaped cross section are fixed to both sides of the cylinder mechanism 2 by hanging fittings 4, respectively.

Reference numerals 5 and 6 denote upper and lower scrapers, which are connected via a connecting rod 7 at intervals equal to the driving stroke of the cylinder mechanism 2, and are guided to the guide frame 3 by the drive of the cylinder mechanism 2, and are moved up and down in conjunction with each other. It is now possible to do so.

That is, the upper scraper j is attached to a bracket 9 provided on the rear surface of the scraper frame 8, as shown in FIGS. 3 and 4.
A wheel 10 rotatably mounted on the guide frame 3 is engaged with the guide frame 3 and connected to the upper end of the connecting rod 7 via a universal joint. Left and right sheet surface cutters 12 are fixed to the front surface of a pedestal 11 supported via a coil spring S for adhesion, and the pedestal is further supported via an inner cutter adhesion plate spring 13 whose base end is fixed to the scraper frame 8. Left and right door frame inner surface cutters 15 are fixed to the outer surfaces of 14, and the inner surface cutters 15
The stopper 16 for the furnace long knife is attached to the base 1 of the sheet surface cutter 12.
It is fixed at 1.

In addition, as shown in FIGS. 5 and 6, the lower scraper 6 has such features that the stopper 16 of the inner cutter 15 does not extend to the lower end, the gap between the lower cutter 15a of the inner cutter 15 and the leaf spring 13 is wide, and the bracket 9 It has substantially the same configuration as the upper scraper j except that the tip of the piston 2a of the silling mechanism 2 is pivotally mounted and the scraper frame 8 is connected to the lower end of the connecting rod 1.

Therefore, the same or corresponding parts are given the same reference numerals as in FIGS. 3 and 4 in FIGS. 5 and 6, and their explanation will be omitted.

Next, the operation of the door frame cleaner configured as above will be explained.

The lid remover 1 is rotated so that the surface provided with the cleaner faces the carbonization chamber of the coke oven from which the lid has been removed, and the lid remover 1 is advanced.

As a result, when the seat surface cutter 12 comes into contact with the seat surface of the door frame, the coil spring S is bent, and as the scraper frame 8 moves further, the frame 14 of the inner cutter 15 tries to move forward, but it bumps into the inner surface of the stopper 16. The leaf spring 13 is bent, and the inner cutters 15 are spread apart from each other via the frame 14 and pressed against the inner surface of the door frame.

In this state, the cylinder mechanism 2 is driven from the upper limit state shown in FIGS. 1 and 2, and the upper and lower scrapers 5.6 are
is reciprocated by the stroke of the cylinder mechanism, and the seat surface cutter 12 scrapes off the seat surface of the door frame, and the inner surface cutter 15 scrapes off adhered carbon on the inner surface.

As described above, the upper scraper 5 cleans the door frame from the upper end to the center, and the lower scraper 6 cleans the door frame from the center to the lower end.

After cleaning, the return drive of the cylinder mechanism 2 causes both scrapers 5.6 to rise and return, the lid remover 1 is moved backward, the coil spring 10 and the leaf spring 13 are restored, and each cutter 12.15 is returned to its original state before operation. This is to return it to its original position.

In addition, 17 in FIGS. 1 and 2 is a coke scraping tool, and as shown in FIGS. 7 and 8, a scraping rod 18, this rod 1
8 moving wheels 19, a cylinder mechanism 20 fixed to the lid remover 1, a scraping rod 18, and a piston 20a of the cylinder mechanism 20.
A connecting rod 21 connecting =: and a guide 23 whose base end is fixed to the lid removal machine 1 and has a switching damper 22,
When the scraping rod 18 moves forward by the drive of the cylinder mechanism 20, the switching damper 22 is lowered by its own weight, and when moving backward, it is pushed down by the wheels 19. When the scraper 5.6 is at the lower limit, the scraping rod 18 is moved forward. By retracting this rod 1B, the kiln raw coke is scraped out at the same time as the door frame is cleaned.

As explained above, according to the present invention, when the stroke interval of the cylinder mechanism is interlocked with one cylinder mechanism, for example, when the stroke interval is 4 times the height of the door frame, at least the upper and lower If two scrapers are provided, the entire height of the door frame can be cleaned.

Therefore, the number of cutters provided can be reduced, and the adhesion between these cutters and the cleaning surface of the door frame of the coke oven can be improved.

Furthermore, since it has two scrapers, one for the upper part and the other for the lower part, it is possible to clean the entire length of the door frame with, for example, one cylinder mechanism, and therefore it is possible to perform good cleaning even though the structure is relatively simple.
