Description

Technical Field

[0001] The present application relates to the technical field of acetylene preparation, and in particular to an acetylene furnace burner plate carbon scraping mechanism which is efficient and easy to disassemble. Background Art

[0002] In the acetylene furnace, the burner plate is a device to prevent the flame from flowing back to the diffuser or to ensure the stability of the flame and reduce the flashback of the gas in the furnace. The burner plate is the core component of the acetylene furnace. The carbon deposition on the inner wall of the burner plate reaction chamber seriously affects the heat transfer and ultimately affects the production efficiency of acetylene.

[0003] In the related art, the burner plates in the existing acetylene furnaces mostly adopt the method of manual carbon scraping. Since the reaction temperature of the acetylene furnace is about 1200 degrees Celsius, the carbon scraping device is mostly in the high temperature range, which is dangerous for manual operation. In order to avoid accidents, the operator can only enter the burner plate reaction chamber to scrape carbon after the device is stopped and the temperature drops to room temperature. This also causes the phenomenon of untimely carbon scraping and even repeated parking, affecting the production efficiency of the enterprise. In addition, the effect of manual carbon scraping is random, because each person's strength and technique vary from person to person. Therefore, we propose an acetylene furnace burner plate carbon scraping mechanism that is efficient and easy to disassemble to solve the above problems. Utility Model Content

[0021] The technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present application provides an acetylene furnace burner plate carbon scraping mechanism that is efficient and easy to disassemble, comprising a radial rotating device 5 fixedly mounted on the outer wall of an acetylene furnace 10 and a radial main control rod 4 fixedly mounted on a mechanical arm 11, wherein:

[0023] The invention also includes a carbon scraping rod 1, a flange lock 1 2, an axial main control rod 3, a radial telescopic rod 6, a flange lock 2 7 and an axial rotation device 8. One end of the radial telescopic rod 6 is inscribed with the end of the radial main control rod 4 away from the mechanical arm 11 and is fixedly sleeved in the radial main control rod 4. The radial rotation device 5 is connected to the radial main control rod 4 through the flange lock 2 7. The radial telescopic rod 6 passes through the radial rotation device 5 and extends into the acetylene furnace 10. The output shaft end of the radial telescopic rod 6 is fixedly connected with a Y-shaped connecting piece 9. The extension or shortening characteristics of the radial telescopic rod 6 can be used to control the movement of the Y-shaped connecting piece 9. The end of the Y-shaped connecting piece 9 located in the acetylene furnace 10 is rotatably installed with the axial main control rod 4. The control rod 3 can realize the six-position movement of the axial main control rod 3, namely, up and down, front and back, left and right, when the radial rotating device 5 and the radial telescopic rod 6 are used together. The axial rotating device 8 is installed under the acetylene furnace 10, and the bottom end of the axial main control rod 3 is connected to the axial rotating device 8. The carbon scraping rod 1 is detachably fixed on the top end of the axial main control rod 3 by a flange lock 2. Ball shaft heads 51 are installed in the radial rotating device 5 and the axial rotating device 8, and a through hole is provided in the middle part of the ball shaft head 51. The radial main control rod 4 penetrates the ball shaft head 51 in the radial rotating device 5, and the bottom end of the axial main control rod 3 penetrates the ball shaft head 51 in the axial rotating device 8.

[0024] In this embodiment, the cross-section of the head of the carbon scraper rod 1 is a regular polygon with 6-36 sides, among which a regular polygon with 18-36 sides is preferred. When the carbon scraper rod 1 makes tangential motion with the inner wall of the burner plate reaction chamber, the purpose of carbon scraping is achieved through the friction between the carbon scraper rod 1 and the burner plate reaction chamber. When the work done by the robotic arm 11 is the same, the friction force is proportional to the actual contact area. Therefore, the more regular polygon sides there are in the cross-section of the scraper head of the carbon scraper rod 1, the larger the actual contact area, the greater the friction force, and the better the carbon scraping effect.

[0025] In this embodiment, an oiling head 52 is fixedly mounted on the outer wall of the radial rotating device 5, and the oiling head 52 is connected to the inside of the radial rotating device 5. By adding lubricating oil from the oiling head 52 to the inside of the radial rotating device 5, the friction resistance of the rod movement can be reduced.

[0026] In this embodiment, the carbon scraping rod 1 is made of GH2747.

[0027] In this embodiment, the structures of flange lock 1 2 and flange lock 2 7 are arranged in the same manner. The flange lock 1 2 is used to facilitate the rapid assembly and disassembly between the carbon scraping rod 1 and the axial main control rod 3. The flange lock 2 7 can be used to realize the rapid assembly and disassembly between the radial rotating device 5 and the radial main control rod 4, thereby realizing a rapid disassembly and connection effect. It should be noted that the operation and use of flange lock 1 2 and flange lock 2 7 are similar to the operation and use of existing clamps, which can realize boltless connection between flanges and achieve the purpose of quick disassembly and quick assembly.

[0028] Through the above-mentioned structure, when the efficient and easy-to-disassemble acetylene furnace burner plate scraper mechanism provided by the present application is in use, the mechanical arm 11 follows a set motion trajectory (the setting of the motion trajectory belongs to the mature technology in this field and will not be repeated in the specification), and the mechanical arm 11 drives the axial main control rod 3 and the scraper rod 1 on the axial main control rod 3 through the radial main control rod 4, the radial telescopic rod 6 and the Y-shaped connecting piece 9 to make circular or Z-shaped trajectory movements around the inner wall of the burner plate reaction chamber, thereby achieving comprehensive and effective scraping of carbon deposits on the inner wall of the burner plate reaction chamber, and ensuring consistent scraping force, so as to improve the heat transfer effect, thereby effectively replacing the manual scraping method and reducing manual labor intensity.

[0029] See also Figure 4 It can be seen that in this embodiment, the robotic arm 11 drives the carbon scraping mechanism to move. Restricted by the radial rotation device 5 and the axial rotation device 8, the carbon scraping rod 1 moves within the range of the inner wall of the burner plate reaction chamber. The purpose of carbon scraping is achieved through repeated friction between the scraping head on the carbon scraping rod 1 and the inner wall of the reaction chamber.

[0030] The above is a detailed introduction to an efficient and easy-to-disassemble carbon scraping mechanism for the burner plate of an acetylene furnace provided by the present application. Specific embodiments are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
