Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coke oven tar plate cleaning device for removing deposits such as tar adhering to a tar plate installed at the bottom of each coke oven kiln.

[0002]

[Prior art]

 In the coke oven, a tar plate is installed under the kiln mouth of each carbonization chamber.The tar plate guides the spilled tar and debris when the furnace lid is removed and the spilled coke that is being pushed into the chain conveyor of the guide car. is there. However, not only fallen bodies and spilled coke on the tar plate, but also tar and the like drop and adhere to the tar plate when the furnace lid is removed. The above-mentioned bodies and spilled coke adhere to and accumulate on the tar that has adhered to this tar plate, making it impossible to install the coke oven lid and contributing to the deterioration of the working environment. There must be.

The time and physical load of the pre-furnace worker involved in this were considerable. For this improvement, it was desired to reduce the work load by mechanical removal methods. As a device for mechanically removing the deposits such as tar deposited on the tar plate, a coke oven door cleaner is actually used in Shokai No. 62-41052, and a coke oven tar pan deposit removing device is actually used. It is disclosed in Kaihei 2-38450. However, these are those in which a nozzle for injecting compressed air is provided in the coke oven door, and a scraping blade is provided in the door hook via the cylinder, and these have the problem that the function is largely restricted. Was there.

[0004]

[Problems to be solved by the device]

 In order to solve the above-mentioned conventional problems, the present invention mechanically removes tar, spilled coke, and debris attached to the tar plate of the furnace front kiln of the coke oven, making it impossible to remove the furnace lid. To prevent the occurrence of. In addition, it can reduce the sticking tar and the wreckage, and completely remove the sticking matter on the frame jaw part, reduce the physical load of tar board cleaning, and improve the functional effect of the kiln mouth blowing device. Thus, the coke oven tar plate cleaning device capable of completely omitting the scraping work is provided.

[0005]

[Means for Solving the Problems]

 The present invention is to solve the above-mentioned problems, and the gist thereof is to have a tar plate at the front kiln opening of a coke oven and suspend a door lifter and a door lifter for attaching and detaching the furnace lid facing the tar plate. In a coke oven in which a lifter rack is installed, a scraper is provided at the lower part of the lifter rack via an elastic arm that faces the tar plate and is pushed downward by a spring mechanism with a required stress. The coke oven tarpaulin cleaning device is characterized in that it is rotatably provided in a pressed state, and that the scraper is pivotally attached to a buffer spring that absorbs a shock in the front-rear direction.

The present invention installs a tar plate cleaning device on the lower part of the lifter rack, scrapes off the stuck tar and debris with a scraper, and uses the forward movement of the lifter when the furnace lid is removed and the frame cleaner is operated. Is. The tar plate is slanted forward and improved so that it works smoothly while being crimped to the slanted surface, and the mounting and shape of the scraping plate under the frame cleaner have been improved. FIG. 1 shows a lifter rack 4 provided with a tar plate cleaning device 5 of the present invention and a lifter 1 suspended on the lifter rack. The lifter 1 is rotatably suspended on the lifter rack 4. When the furnace lid is attached or detached, the furnace lid is hooked on the hook of the lifter 1 and rotated by 90 degrees to stop at a predetermined position. When the furnace lid is to be housed, the lifter 1 advances in the direction of the coke oven, moves to the position where the furnace lid is inserted into the coke oven kiln, and sets the oven lid completely, and the lifter stops at the specified position. Then remove the hook.

The tar plate cleaning device 5 of the present invention pays attention to the forward and backward movements and the vertical movements of the door lifter 1, and by utilizing the movement operation at the time of attaching and detaching the furnace lid, a power source is not required. The equipment cost is reduced. As shown in FIG. 1, other existing cleaning devices include a door cleaner 6 and a frame cleaner 2, which are conventionally known and clean the periphery of a furnace lid with compressed air and a scraping plate at the bottom, respectively. Is. The tar plate cleaning device 5 of the present invention can be used in combination with these other cleaners, which does not impair the gist of the present invention. Next, the present invention will be described in more detail based on examples.

【Example】

 FIG. 2 is an enlarged plan view showing an essential part of the tar plate cleaning device of the present invention. As shown in FIG. 2, the device of the present invention is provided under the lifter rack 4 and between the coke oven tar plate. The scraper 9 for scraping the tar plate is engaged with an arm having two slide portions 7, and the end portion of this arm portion is fixed to the lower portion of the lifter rack 4 with a bolt through a mounting plate. Further, since the scraper 9 is in pressure contact with the tar plate 10, it always receives an impact in the front-rear direction, and in order to absorb the impact, a plurality of buffer springs 8 are axially attached to the frame portion fixed to the lifter rack 4. There is. In the present invention, when the lifter rack 4 advances, the scraper 9 presses against the tar plate 10 of the coke oven, and the forward force of the lifter rack 4 moves the scraper 9 from the lower end of the tar plate 10 to the upper end to scrape off the deposits. Clean it.

The device of the present invention is shown in a side view in FIG. 3 mainly for the operation of the scraper 9. The scrubber 9 is engaged with the arm 8 and the slide portion 7, the slide portion 7 is constantly pressed downward by the pressure contact spring 11, and the scraper 9 is rotatable upward from the horizontal position. When the lifter rack 4 moves forward, the scraper 9 is pressed against the tar plate 10 and moves while scraping the tar plate 10 from below to above. Further, the attached matter scraped off by the scraper 9 is carried out by the chain conveyor 12. Next, a method of using the device of the present invention will be described.

As shown in FIG. 4, when the furnace lid is removed by the lifter 1, the lifter rack 4 as shown in FIG. 4A moves forward to align the hook of the lifter 1 with the hook position of the furnace lid 13. . At this time, the tar plate cleaning device 5 scrapes off the deposits on the tar plate as the lifter rack 4 advances. Similarly, in the case of housing the furnace lid, the tar plate 10 is scraped and cleaned by moving the lifter rack 4 forward while the furnace lid 13 is suspended. As described in the above embodiments, the device of the present invention removes the deposits by pressing the scraper against the tar plate when the lifter rack advances when the coke oven tar plate is removed. It is possible.

[0011]

[Effect of device]

 The present invention significantly reduces tars and debris that have adhered and can completely remove the adhered substances on the frame jaws, reducing the physical load on the operator who cleans the tar plate, and further improving the kiln mouth blowing device. The efficiency can be improved and the scraping work can be omitted.
