DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0025] Reference Figures 1-6 , suitable for blast furnace thermocouple fixing tooling of different specifications: including a blast furnace 1, a fixing mechanism 4 is installed on the side wall of the blast furnace 1; the fixing mechanism 4 includes an outer fixing disk 41, a plug-in tube 42 is fixedly installed on the inner side of the outer fixing disk 41, a vacuum cavity 43 is opened on the inner side of the plug-in tube 42, an asbestos heat insulation sheet 44 is provided on the inner side of the vacuum cavity 43, an internal threaded abutting column 45 is screwed on the inner side of the plug-in tube 42, a plug-in hole 49 is opened on the inner end of the plug-in tube 42, a thermocouple 410 is plugged into the inner side of the plug-in hole 49, a bottom clamping seat 411 is fixedly connected to the bottom of the thermocouple 410, and the bottom clamping seat 411 is plugged into the inner side of the plug-in tube 42, and a mounting hole 3 is opened on the side wall of the blast furnace 1.

[0026] In this embodiment, an inner groove 47 is formed at the inner end of the internal threaded abutting column 45 . An abutting gasket 48 is installed inside the inner groove 47 . The abutting gasket 48 abuts against the bottom clamping seat 411 . The abutting gasket 48 is made of rubber.

[0027] Through the above-mentioned setting, the abutment gasket 48 is made of rubber material, so that the abutment gasket 48 has a certain elasticity. Its elasticity is used to stably abut the bottom clamping seat 411 at the bottom of the thermocouple 410 against the inner side of the plug-in tube 42, making the abutment and fixation of the thermocouple 410 more stable.

[0028] In this method, the external fixed plate 41 is screwed and installed on the outer wall of the blast furnace 1. The bottom of the thermocouple 410 is electrically connected to the transmission cable 413. The transmission cable 413 passes through the abutment gasket 48, the internal thread abutment column 45 and the mounting base 46 in sequence. The controller 2 is fixedly installed on the outer wall of the blast furnace 1, and the controller 2 is electrically connected to the lower end of the transmission cable 413.

[0029] With the above arrangement, the controller 2 can receive the temperature information of the inside of the blast furnace 1 fed back by the thermocouple 410 in real time through the transmission cable 413 .

[0030] In this embodiment, a plurality of stiffening ribs 414 are fixedly installed on the inner side of the vacuum chamber 43 , and the stiffening ribs 414 are made of micro-nano thermal insulation strips.

[0031] Through the above-mentioned setting, the vacuum chamber 43 has good thermal insulation function. At the same time, the stiffening ribs 414 strengthen the structural strength inside the vacuum chamber 43. The stiffening ribs 414 are made of micro-nano thermal insulation strips. Due to their unique microstructure design, the micro-nano thermal insulation strips can still maintain good thermal insulation performance in high temperature environments and are widely used in industrial furnaces, heat treatment equipment and other fields.

[0032] In this embodiment, a coupling washer 412 is provided between the plug hole 49 and the thermocouple 410 , and the coupling washer 412 is made of microporous ceramic material.

[0033] Through the above-mentioned arrangement, the microporous ceramic material has strong structural strength and excellent thermal insulation performance. Through the arrangement of the vacuum chamber 43, the asbestos thermal insulation sheet 44 and the coupling gasket 412, the entire plug-in tube 42 has structural continuous thermal insulation performance, so that the interior of the plug-in tube 42 is not affected by the high temperature inside the blast furnace 1.

[0034] In this embodiment, the plug-in tube 42 is inserted into the inner side of the mounting hole 3 , and the inner end of the plug-in tube 42 passes through the inner side of the blast furnace 1 .

[0035] In this embodiment, a mounting base 46 is fixedly mounted on the outer end of the internal thread abutment column 45 , and the mounting base 46 is in the shape of an equilateral hexagon.

[0036] With the above arrangement, the mounting base 46 is arranged in an equilateral hexagonal shape, which facilitates installation or plugging by twisting the internal thread abutting column 45 through the mounting base 46 with an auxiliary wrench.

[0037] In this embodiment, a high-temperature resistant sealing gasket is provided inside the mounting hole 3 .

[0038] By the arrangement in the above manner, the high temperature resistant sealing gasket provided inside the mounting hole 3 ensures the sealing performance of the connection between the plug-in tube 42 and the inner side of the mounting hole 3 .

[0039] The working principle of the blast furnace galvanic couple fixing fixture applicable to different specifications provided by the utility model is as follows:

[0040] During use, when the blast furnace is heated to high temperature, the temperature is transferred to the thermocouple 410, which uses the electromotive force generated by two different metal conductors under temperature difference to measure the temperature. The detected temperature information is transmitted to the controller 2 on the outside through the transmission cable 413, and then the controller 2 can monitor the operating temperature inside the blast furnace 1 in real time. When the thermocouple 410 needs to be replaced or repaired later, use the auxiliary wrench to twist the installation base plate 46, and remove the internal threaded abutment column 45 from the inside of the plug-in tube 42. Then, pull out the thermocouple 410 and the coupling gasket 412 inside the plug-in hole 49 from the inside, and then simultaneously plug the repaired or newly installed thermocouple 410 and its corresponding coupling gasket 412 into the inside of the plug-in hole 49, and then twist the internal threaded abutment column 45 to install the thermocouple 410 against the inside of the plug-in tube 42.

[0041] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
