[0002] Oxygen-burning operations are frequently used in the steel production process, such as cleaning the water inlet of steelmaking ladles, draining ladles that do not open automatically, cutting of casting residues from medium ladles and large scrap steel, etc.

[0003] The oxygen burning devices currently in use have the following main defects: 1. During the oxygen burning process, the oxygen hose and the oxygen burning iron pipe are not fixed, and people rely on holding the interface between the oxygen hose and the oxygen burning iron pipe with their hands to fix them; 2. The oxygen hose at the interface is aging, the interface gap is large, and the air leakage is serious; 3. Backfire at the interface will quickly explode, causing serious harm to personnel.

[0004] To this end, those skilled in the art have proposed an oxygen-fired drainage and anti-flashback device to solve the problems raised in the background art. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an oxygen-burning drainage and anti-flashback device to solve the problems in the prior art.

[0006] An oxygen-burning drainage and flashback prevention device, comprising:

[0007] An oxygen hose, one end of which is movably connected to an oxygen-burning iron pipe, and a protective component is sleeved on the oxygen hose;

[0008] The protection component includes a first anti-flashback sleeve, one end of which is fixedly connected to a second anti-flashback sleeve, the second anti-flashback sleeve is sleeved on the ferrous oxide pipe, and one end of the ferrous oxide pipe extends out of one end of the second anti-flashback sleeve.

[0009] Preferably, a threaded hole and a receiving hole are provided on the first anti-backfire sleeve.

[0010] Preferably, a limiting screw is threadedly connected to the threaded hole, and a handle is fixedly connected to the top of the limiting screw.

[0011] Preferably, a connecting pipe is provided in the accommodating hole, and the connecting pipe is fixedly connected to the first anti-flashback sleeve.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model provides a handle and a limit screw, so that the oxygen hose is reliably connected to the protective component, thereby preventing the oxygen hose from falling off.

[0014] 2. The utility model is detachably connected to the oxygen hose and the oxygen-burning iron pipe, and the oxygen hose or the oxygen-burning iron pipe can be replaced at any time to avoid the risk of leakage caused by aging.

[0015] 3. The utility model allows argon or nitrogen to enter the protective component through the setting of the connecting pipe, thereby preventing the occurrence of flashback and avoiding scalding of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown:

[0023] Embodiment 1: The utility model provides an oxygen-fired drainage anti-flashback device, comprising an oxygen hose 1 for conveying oxygen, one end of the oxygen hose 1 being movably connected to an oxygen-fired iron pipe 2, and a protective component 3 being sleeved on the oxygen hose 1;

[0024] The protection component 3 includes a first anti-flashback sleeve 31, one end of which is fixedly connected to a second anti-flashback sleeve 32, the second anti-flashback sleeve 32 is sleeved on the ferrous oxide pipe 2, and one end of the ferrous oxide pipe 2 extends out of one end of the second anti-flashback sleeve 32.

[0025] Furthermore, a threaded hole 33 and a receiving hole 34 are provided on the first anti-backfire sleeve 31, a limiting screw 35 is threadedly connected to the threaded hole 33, a handle 36 is fixedly connected to the top of the limiting screw 35, a connecting pipe 37 is provided in the receiving hole 34, and the connecting pipe 37 is fixedly connected to the first anti-backfire sleeve 31.

[0026] It should be noted that one end of the oxygen hose 1 is connected to oxygen, and one end of the connecting pipe 37 is connected to an argon pipeline. A valve is provided, wherein the argon can be replaced by nitrogen.

[0027] As can be seen from the above, when oxygen burning work is required, the oxygen burning iron pipe 2 is connected to the oxygen hose 1, and the oxygen burning iron pipe 2 is inserted into the first anti-flashback sleeve 31 and passed through one end of the second anti-flashback sleeve 32. By turning the handle 36, the limit screw 35 is rotated, thereby limiting the position of the oxygen hose 1 to prevent the oxygen hose 1 from slipping out of the first anti-flashback sleeve 31 during use. At the same time, the valve on the connecting pipe 37 is opened to allow argon or nitrogen to enter the first anti-flashback sleeve 31, thereby preventing the fire source from flashing back from the oxygen burning iron pipe 2, thereby protecting the staff from being burned. The staff holds the first anti-flashback sleeve 31 to perform oxygen burning work.

[0028] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention.
