A leak-proof pipe connection structure for burner nozzles in an all-oxygen ladle oven. Technical Field

[0001] This utility model belongs to the field of ladle technology, and in particular relates to a leak-proof structure for pipe connection of burner in an oxygen-filled ladle baker. Background Technology

[0002] In the steel smelting industry, the oxygen-fired ladle oven is a key piece of equipment that plays a vital role in improving the quality of molten steel and reducing production costs. The burner is one of the core components of the oxygen-fired ladle oven, and its connection with the pipeline directly affects the oven's operational stability and energy efficiency. Therefore, a reliable leak-proof structure for the pipeline connection of the burner to the oxygen-fired ladle oven is a key element in ensuring smooth production.

[0003] However, the existing pipe connection and leak-proof structure for burners in all-oxygen ladle ovens is inconvenient to install, requiring complex operations to install the connection structure, which reduces the efficiency of ladle oven installation and maintenance and increases equipment downtime. Summary of the Invention

[0004] The purpose of this utility model is to provide a leak-proof structure for the pipe connection of the burner in an oxygen-filled ladle oven. By setting up a quick installation mechanism, it solves the problem that the existing leak-proof structure for the pipe connection of the burner in an oxygen-filled ladle oven is inconvenient to install and requires complicated operations to install the connection structure, thereby reducing the efficiency of the installation and maintenance of the ladle oven and increasing the downtime of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a leak-proof pipe connection structure for a burner of an oxygen-filled ladle oven, including a burner pipe, a pipe on the left side of the burner pipe, and a number of quick-installation mechanisms and a number of anti-detachment connection mechanisms on the burner pipe and the pipe.

[0007] The burner pipe and the outer wall of the pipe are both provided with mounting rings. The quick installation mechanism includes a mounting groove opened on the mounting ring located on the right side. A cylindrical shell is fixedly connected to the inner wall of the mounting groove. A sliding rod passes through the cylindrical shell and is slidably connected to the cylindrical shell. A spring is sleeved on the outer wall of the sliding rod. The top of the spring is fixedly connected to the cylindrical shell. The anti-detachment connection mechanism includes bolts provided on the burner pipe.

[0008] Furthermore, a slider is fixed to the outer wall of the slide rod, the outer wall of the slider is slidably connected to the cylindrical shell, the top of the slider is fixedly connected to a spring, a limiting groove is opened on the burner pipe, the bottom of the slide rod is in contact with the limiting groove, and a handle is fixedly connected to the top of the slide rod.

[0009] Furthermore, both pipes are fixedly connected to the outer walls of a fixing ring. A sealing ring is fixedly connected to the left side of the fixing ring on the right side, and a sealing groove is provided on the right side of the fixing ring on the left side. The outer wall of the sealing ring is in contact with the sealing groove.

[0010] Furthermore, both of the fixing rings are provided with threaded grooves, the bolt is threadedly connected to the two threaded grooves, a limit block is provided on the outer wall of the bolt, the outer wall of the bolt is in contact with the limit block, and a rectangular groove is provided on the limit block.

[0011] Furthermore, a second rectangular groove is provided on the bolt, and an elastic buckle is provided on the first rectangular groove, with the outer wall of the elastic buckle in contact with the second rectangular groove.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a quick installation mechanism, when starting the installation, first lift the four handles on the installation ring and press one of them. The handle will drive the slide rod to rise, which in turn drives the slider to rise. The slider rises inside the cylindrical shell, compressing the spring and causing it to contract until the bottom of the slide rod retracts into the cylindrical shell. Place the installation ring on the burner pipe and adjust it so that the center of the installation groove and the limiting groove are aligned. Then release the handle. The spring rebounds and drives the slider to return to its original position. The slide rod will return to its original position along with the slider, thus locking into the corresponding limiting groove. This completes the installation of the installation ring on the burner pipe. Similarly, installing the installation ring on the pipe completes the installation of the device. This allows for simple operation to complete the installation of the connection structure, greatly shortening the installation time and improving the efficiency of the installation and maintenance of the ladle oven, thus reducing equipment downtime.

[0014] 2. By setting up an anti-detachment connection mechanism, after the installation ring is installed, the two fixing rings are fitted together. At this time, the sealing ring will fit against the inner wall of the sealing groove, aligning with the threaded groove on it. Four bolts are used to connect the two fixing rings through several threaded grooves. Then, the limiting block is installed. Taking one as an example, the others are the same. The limiting block is inserted into the bolt, and the adjustment is made to align rectangular groove one and rectangular groove two. Then, the elastic buckle is pressed so that its two sides contact each other, and then it passes through rectangular groove one and rectangular groove two. Then, the elastic buckle is released, and the installation of the anti-detachment connection mechanism is completed. The limiting block and elastic buckle will lock the bolt to prevent it from falling off, which can ensure that the pipeline connection always remains in a tight state, avoid pipeline separation due to vibration, and ensure the structural integrity and stability of the pipeline system for the burner of the all-oxygen ladle oven.
