[0002] The double de-C furnace zirconia analyzer has serious dust and high humidity in the furnace, which can easily clog the zirconia detector and the guide tube, making it impossible to perform measurements, resulting in unstable process operations and seriously affecting the smooth production of the device. This technical transformation will solve this problem.

[0003] The oxygen content of the C furnace of the double degassing device directly affects the stable operation of the heating furnace. Due to the installation of zirconia, there is a large amount of dust and humidity in the inlet pipe of the heating furnace, which is easy to cause the detector and the guide pipe to be blocked by coking, and the cleaning is frequent, affecting the process operation. This transformation uses the original gas path increase and adds a two-position three-way solenoid valve for timed backblowing. The time is set by the zirconia converter. After the transformation, the effect is obvious. From the original two or three weeks of dismantling and cleaning, there has been no blockage problem for half a year. The maintenance workload is greatly reduced to ensure the smooth operation of the process.

[0004] Therefore, it is necessary to redesign the double de-C furnace to effectively prevent the double de-C furnace from being easily blocked when working for a long time, which reduces the working efficiency of the double de-C furnace. Utility Model Content

[0025] A furnace body 2 is arranged on the top of the cabinet body 1, a flow guide pipe 3 is connected to the surface of the furnace body 2, and a backflush mechanism 4 is fixedly connected to the left side of the inner wall of the cabinet body 1;

[0026] The back-blowing mechanism 4 includes a controller 41, a connecting line 42, a three-way solenoid valve 43, a back-blowing air pipe 44 and a converter 45. The controller 41 is fixedly connected to the left side of the inner wall of the cabinet 1, and the right side of the controller 41 is electrically connected to the three-way solenoid valve 43 through the connecting line 42. The right side of the three-way solenoid valve 43 is connected to the back-blowing air pipe 44, and the back-blowing air pipe 44 is connected to the guide pipe 3 away from the three-way solenoid valve 43. The converter 45 is fixedly connected to the left side of the inner wall of the cabinet 1 and located at the bottom of the controller 41, and the top of the converter 45 is electrically connected to the three-way solenoid valve 43 through a wire.

[0027] refer to Figure 2 The right side of the controller 41 is fixedly connected with an anti-slip ring 5 which is sleeved on the surface of the connecting line 42 and is used in conjunction with the connecting line 42 .

[0028] As a technical optimization solution of the present invention, the anti-slip ring 5 can assist the connection line 42 in working and play a fixing role, thereby avoiding the connection line 42 from breaking during the pulling process.

[0029] refer to Figure 4 A rubber sleeve 6 is fixedly sleeved on the surface of the connecting wire 42 , and the rubber sleeve 6 is used in conjunction with the connecting wire 42 .

[0030] As a technical optimization solution of the utility model, the setting of the rubber sleeve 6 can assist the connection line 42 in working and play a protective role, thereby avoiding the connection line 42 from cracking due to thermal expansion and contraction.

[0031] refer to Figure 1 The back-blowing air pipe 44 is connected to the flow guide pipe 3 , and the back-blowing air pipe 44 and the flow guide pipe 3 are used in conjunction with each other.

[0032] As a technical optimization solution of the utility model, the back-blowing air pipe 44 is provided to assist the flow guide pipe 3 in working, thereby avoiding the phenomenon that the back-blowing air pipe 44 cannot be connected with the flow guide pipe 3 and causes blockage.

[0033] refer to Figure 1 The controller 41 is electrically connected to the three-way solenoid valve 43 through a connecting line 42, and the controller 41 and the three-way solenoid valve 43 are used in conjunction with each other.
