Description

Technical Field

[0001] The present application relates to the technical field of blast furnace smelting, and in particular to a connection device for opening an iron hole by blowing oxygen. Background Art

[0002] The blast furnace is equipped with an iron mouth, opening equipment (opening machine), plugging equipment (mud gun), and iron mouth plugging gun mud. In the normal production process, within the specified time, the opening machine equipment is required to drill the iron mouth to discharge the liquid iron and slag. After the iron is tapped, the mud gun equipment is required to press the refractory mud into the iron mouth channel to seal the iron mouth, thereby completing the normal iron mouth opening and plugging work to ensure the continuous production of the blast furnace.

[0003] When the opening machine fails, the quality of mud blocking changes, mud comes out of the iron mouth, the furnace condition deteriorates, and the opening machine cannot drill the iron mouth due to improper operation in front of the furnace, the blast furnace is suffocated and the wind is reduced. When the iron mouth cannot be drilled in the above situation, artificial oxygen burning is required in the blast furnace.

[0004] In the prior art, one end of an oxygen burning tube is inserted into the iron mouth, and the other end is connected to the iron mouth of the blast furnace by the oxygen burning tube. The oxygen burning tube is ignited to melt the solidified slag iron in the iron mouth channel and blown clean until the cannon mud and the slag iron mixture at the red dot in the iron mouth channel are burned through and the slag iron flow is seen. However, this operation of opening the iron mouth by burning oxygen requires first tying the oxygen hose and the oxygen burning tube. Each time the iron mouth is opened by burning oxygen, more than 5 oxygen burning tubes need to be used. Therefore, it is necessary to repeat the untying and tying more than 5 times, resulting in a lot of time waste. If the iron mouth is not opened for a long time, it will cause slow wind or wind stop in the blast furnace, which will directly affect the production efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art mentioned above, the purpose of the utility model is to provide a connecting device for opening the iron mouth for oxygen blowing, which is used to solve the problem that the oxygen burning pipe needs to be repeatedly untied and tied many times in the prior art, resulting in a large amount of time waste. If the iron mouth is not opened for a long time, it will cause slow wind or stop wind in the blast furnace, directly affecting the production efficiency.

[0006] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides a connection device for opening an iron hole by blowing oxygen, comprising:

[0007] A connecting tube group, the connecting tube group comprising a first tube and a second tube, a first end of the first tube and a first end of the second tube being vertically connected, and a chamfer is provided at a connection between the first tube and the second tube;

[0008] The second end of the first tube is provided with a connecting platform for connecting with the oxygen-burning tube.

[0009] Optionally, the second end of the second tube is evenly provided with a limiting groove for connecting with the oxygen hose, and the cross-section of the limiting groove is triangular.

[0010] Optionally, the first end of the first tube is also sleeved with a hand-held tube.

[0012] Optionally, the hand-held tube is also provided with a force-bearing component for receiving hand pushing force.

[0013] Optionally, the force-bearing component includes a force-bearing plate, which is vertically arranged on the hand-held tube and fixedly connected to the hand-held tube.

[0014] Optionally, the force-bearing component includes a mounting hole and a force-bearing bolt, the mounting hole is opened on the hand-held tube, and the force-bearing bolt is passed through the mounting hole.

[0015] As described above, the beneficial effects brought about by the technical solution in the utility model include at least: a connecting platform is set at the second end of the first tube, the oxygen burning tube can be quickly clamped on the connecting platform to complete the connection between the oxygen burning tube and the connecting platform, and a single operator can complete the installation of the oxygen burning tube, saving human resources and reducing the difficulty of operation.
