Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of carbonization chamber cleaning devices, and in particular to an automatic cleaning device for coke oven carbonization chambers. Background Technology
[0002] During the production and operation of a coke oven carbonization chamber, factors such as high coke oven temperatures and the collapse of the coal cake tail lead to the formation of graphite on the top of the carbonization chamber. If the graphite on the top of the carbonization chamber is not cleaned in a timely manner, it will gradually accumulate, causing difficulties in pushing coke, and even perforation and air leakage in the furnace wall, as well as deformation. In severe cases, it will affect the normal operation of the coke oven. Therefore, it is necessary to clean the graphite on the top of the coke oven regularly. However, currently, the cleaning of the top of the carbonization chamber is done manually, which requires stopping the machine and poses certain potential risks to the cleaning personnel. The other method is dry burning, but dry burning has significant negative effects, affecting both coke yield and quality. In response, this application proposes an automatic cleaning device for the coke oven carbonization chamber, providing a new cleaning method. Utility Model Content
[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides an automatic cleaning device for the coke oven carbonization chamber. The technical solution it solves is as follows: it includes a coke pusher head, characterized in that a positioning device is fixedly connected to the right side of the coke pusher head, a T-shaped plate is slidably mounted on the positioning device, an extension plate is fixedly connected to the upper end of the T-shaped plate, a scraper is fixedly connected to the upper end of the extension plate, a connection hole is provided on the T-shaped plate, and a quick fastening device that cooperates with the connection hole is arranged at the upper end of the coke pusher head.
[0004] The quick fastening device includes a support plate fixedly connected to the upper end of the coke pusher head. A drive rod arranged laterally is rotatably connected to the middle of the support plate. Two sliding rods arranged symmetrically about the drive rod are fixedly connected to the right end of the support plate. The two sliding rods are slidably connected to the two ends of a moving rod. An internal threaded sleeve is integrally connected to the middle of the moving rod. A screw part that is threadedly connected to the internal threaded sleeve is integrally connected to the drive rod. A plug rod corresponding to the connecting hole is fixedly connected to the right end of the internal threaded sleeve. A nut is integrally coaxially connected to the left end of the drive rod.
[0005] Preferably, the positioning device includes two right-angle buckles fixedly connected to the upper part of the focus pusher head, and a T-shaped block fixedly connected to the lower part of the focus pusher head.
[0006] Preferably, the two buckles are slidably engaged with the front and rear sides of the T-shaped plate, and the lower end of the T-shaped plate is provided with a limiting groove for sliding engagement with the T-shaped block.
[0007] Preferably, the insertion rod is coaxially fixedly connected to a baffle that abuts against the left end of the T-shaped plate.
[0008] The beneficial effects of this utility model are:
[0009] In use, the T-shaped plate of this application can be initially positioned and installed on the right end of the coke pusher head using a positioning device, and can be quickly fixed using a fastening device. This application not only allows for quick positioning and fastening but also facilitates disassembly. After the T-shaped plate is fixed, during the operation of the coke pusher head, the scraper connected to the T-shaped plate via the extension plate can efficiently clean the graphite accumulated on the top of the carbonization chamber. In addition, since the coke pusher head cannot safely penetrate deep into the carbonization chamber due to the influence of coal cake, the scraper of this application is installed on the T-shaped plate via the extension plate, ensuring that the scraper can penetrate deeper relative to the coke pusher head, thereby ensuring the cleaning area of the top of the carbonization chamber and ensuring the cleaning effect.

[0016] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.
[0017] In the first embodiment, the technical solution is that, during use, the T-shaped plate 2 can be initially positioned and installed on the right end of the coke pusher head 1 by a positioning device, and can be quickly fixed by a fastening device 6. This application not only allows for quick positioning and fastening but also facilitates disassembly. After the T-shaped plate 2 is fixed, during the operation of the coke pusher head 1, the scraper 4 connected to the T-shaped plate 2 by the extension plate 3 can efficiently clean the graphite accumulated on the top of the carbonization chamber. In addition, since the coke pusher head 1 cannot safely penetrate deep into the carbonization chamber due to the influence of coal cake, the scraper 4 of this application is installed on the T-shaped plate 2 by the extension plate 3, ensuring that the scraper 4 can penetrate deeper relative to the coke pusher head 1, thereby ensuring the cleaning area of the top of the carbonization chamber by the scraper 4 and ensuring the cleaning effect.
[0018] In Example 2, based on Example 1, specifically, the left end of the coke pusher head 1 of this application is fixedly connected to the existing coke pusher rod. When it is necessary to clean the graphite at the top of the carbonization chamber, the T-shaped plate 2 is first slid in from the upper end of the positioning device for initial restraint. Specifically, the bottom of the T-shaped plate 2 is slid down along the right-angle buckle 15 at a certain speed until it is as shown in the attached drawings of the specification. Figure 2 As shown, the limiting groove 17 of the T-shaped plate 2 is fully engaged with the T-shaped block 16, and the front and rear sides of the T-shaped plate 2 are restricted by the right-angle buckle 15. Then, the drive rod 8 of the quick fastening device 6 is rotated clockwise. To facilitate the rotation of the drive rod 8, a nut 14 is provided. The operator can quickly rotate the drive rod 8 by using a socket wrench in conjunction with the nut 14. When the drive rod 8 rotates clockwise, the screw part 12 rotates clockwise as well. The clockwise rotation of the screw part 12 will act on the internal thread sleeve 11 on the moving rod 10, thereby driving the internal thread sleeve 11 and the moving rod 10 together to move to the right along the slide rod 9. Then, the insertion rod 13 will move to the right and be inserted into the connecting hole 5, so that the baffle 18 abuts against the left end of the T-shaped plate 2, thus completing the fastening of the T-shaped plate 2. After fastening, as the coke pusher head 1 pushes the coke along with the coke pusher rod, the T-shaped plate 2 will move in the carbonization chamber. Then, the scraper 4 connected to the T-shaped plate 2 via the extension plate 3 will move synchronously and automatically clean the graphite on the top of the carbonization chamber.
[0019] In Example 3, based on Example 2, after the cleaning operation is completed, when it is necessary to disassemble the T-shaped plate 2, the drive rod 8 on the support plate 7 is rotated counterclockwise using a socket wrench and nut 14. This causes the screw portion 12, integrally arranged with the drive rod 8, to act on the threaded sleeve, causing the inner threaded sleeve 11 and the moving rod 10 to move to the left along the slide rod 9. This allows the insertion rod 13 to disengage from the positioning hole, thereby allowing the T-shaped plate 2 to move upwards and disengage from the positioning device, thus completing the disassembly. To protect the quick-fastening device 6, a protective cover can also be arranged on the upper end of the coke pusher head 1; this will not be described in detail in this application.
