Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a coke oven front wreckage treatment device.

“Prior Art” A conventional tar pan cleaner is provided with a tar pan that is inclined downward toward the platform just below the contact surface of the furnace lid, and a small gap is present between the lower edge of the tar pan and the upper surface of the platform. Was there. Therefore, it suffices to dispose a scraper conveyor in the gap in a direction parallel to the rail on the furnace side, and carry out tar and debris onto the chassis of a work machine in front of the furnace such as a coke guide car. However, in a coke oven of the type in which tar and debris are dropped onto the platform by an inclined surface from just below the contact surface of the furnace lid to the platform, there is no gap and there is no drop, so the falling from the inclined surface to the platform is reduced. There was no other way than removing the corpses and tar on the slopes manually.

“Problems to be solved by the device” The present invention aims to carry out tar and debris smoothly and promptly without using human power when the platform is in contact with the inclined surface directly below the contact surface of the furnace lid as described above. It is intended.

"Means for solving the problems" In order to achieve the above-mentioned object, the present proposal is to form an inclined surface from immediately below the surface of the coke oven to cover the furnace lid to the work platform before the furnace, and to connect the furnace side and the furnace side laid on the platform. In a furnace front working machine, a coke guide vehicle, or an independent chassis moving on a rail on the anti-reactor side, a slide table capable of ascending and descending along a guide inclined downward toward the inclined surface is provided, and the lower end of the slide table A scraping scraper for cleaning the inclined surface is provided to be movable up and down, a falling body scraping guide plate that is inclined upward from the furnace side rail toward the counter furnace side is provided, and the upper end portion of the guide plate is dropped. Specified invention is a coke oven falling body treatment device installed on a body discharge conveyor, side plates are provided on both sides of a falling body scraping guide plate, and one side plate is formed to be openable and closable. Coke oven decimator treatment device, scrape scraping plan The middle part of the lower surface of the inner plate is rotatably supported by a horizontal pin on the conveyor box so as to be able to move up and down, and the lower end of the inner plate is held by a small wheel traveling on the furnace side rail on the upper surface of the rail via a small gap. It is configured by the coke oven falling body treatment device described in each of the above inventions.

[Operation] Therefore, in cleaning the falling bodies accumulated on the inclined surface 4 and the platform 3 just below the furnace lid 17 'and the tar on the inclined surface 4, the slide base 8 is guided along the guide 7. Descend and raise the scraper 9 to the position shown by the solid line in FIG.
Further, when it is rotated to the position indicated by the phantom line in FIG. 1, the tip of the scraper 9 contacts the inclined surface 4. When the slide base 8 is moved obliquely upward along the guide 7 while being further rotated downward, the tip of the scraper 9 scrapes off the debris and tar on the inclined surface 4 onto the platform 3, and further scrapes this. The upper surface of the furnace-side rail 5 is scraped onto the guide plate 10 and scraped from the upper end of the guide plate 10 onto the carry-out conveyor 11, and this operation is repeated. Then, the conveyor 11 can be carried out from the upper part of the chassis 6 to the rear.

The scraps and tar that are guided up by the side plates 12 and 13 on both sides of the guide plate 10 and scraped up are transferred onto the conveyor 11, but when the chassis 6 moves along the rail 5, the scraps and
The tar is scraped by the side plate 12, and the side plate 13 is opened. When it moves to the front of the coke oven 1 and the position is determined, the side plate 13 is closed so that the falling body on the platform 3 can be removed from both side plates.
It can be stored between 12 and 13, and is scraped up by the scraper 9.

The lower end of the guide plate 10 always has a small gap t on the upper surface of the furnace-side rail 5, and the lower end does not come into contact with the rail 5 to generate frictional heat.

[Example] A furnace lid contact surface 2 is provided on the outer periphery of the kiln opening of the coke oven 1, and an inclined surface 4 reaching the furnace front work platform 3 is formed immediately below the lower contact surface 2. The inclined surface 4 is provided as a descending guide surface for tar and fallen bodies. On the platform 3, run rails 5 and 5'are laid on the furnace side and the counter furnace side,
A work machine, a coke guide vehicle or an independent chassis 6 is attached to the rail 5,
Move along 5 '. The carriage 6 is provided with fixed parallel guides 7, 7 which are inclined downward toward the inclined surface 4,
The guides 7, 7 are provided with a slide base 8 which can be slid up and down by a cylinder 17. A cleaning scraper 9 for the inclined surface 4 is provided at the lower end of the slide base 8 so as to be vertically rotatable by a cylinder 19 around a horizontal pin 18 parallel to the rails 5 and 5 '. Further, there is provided a falling body scraping guide plate 10 which is inclined upward from the upper surface of the furnace side rail 5 toward the side opposite to the furnace substantially parallel to the guide 7, and the upper end portion of the guide plate 10 is provided with a falling body carry-out conveyor 11 Place on top. The conveyor 11 is constructed by installing a scraper 20 between two parallel chains 11 ', 11', and a starting end sprocket 21 is made to face under the guide plate 10. Side plates 12 and 13 are provided on both sides of the falling body scraping guide plate 10, and one side plate 13 is supported so as to be openable and closable by 90 degrees around an upright pin 22 and is opened and closed by a cylinder 23. Also this guide plate 10
The lower middle part of the conveyor 11 is rotatably supported by a machine pin 14 of the conveyor 11 by a horizontal pin 15 so as to be able to move up and down. The small wheel 16 is pivotally supported on the small wheel.
By supporting 16 and 16 on the upper surface of the furnace-side rail 5, a small gap t is formed between the lower end of the guide plate 10 and the upper surface of the rail 5.
Is intervening. Reference numeral 25 in the figure denotes a drive sprocket for the conveyor 11, and 26 denotes a drive motor.

[Effect] Since the present plan is configured as described above, in the kiln opening portion provided with the sloped surface 4 such as a falling body, tar, etc., from directly below the furnace lid contact surface 2 of the coke oven 1 to the platform 3,
It is possible to quickly and easily carry out the debris and tar accumulated on the platform 3 from the inclined surface 4 to the reactor side without requiring human power.

In addition, accumulated debris and tar can be accommodated between both side plates 12 and 13 of the guide plate 10 and can be scraped off smoothly into the conveyor 11 without dropping from both sides of the guide plate 10.

Further, the lower end of the guide plate 10 can be smoothly moved up and down along the ups and downs of the upper surface of the furnace-side rail 5, and the small gap t can be maintained, so that the risk of frictional heat can be prevented.
