[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] In the related art, the blast furnace tuyere monitoring device at the tuyere peephole includes a main channel connected to the tuyere, and at least two branch channels connected to the main channel. Different branch channels can be used to set temperature detectors or for manual observation. The blast furnace tuyere monitoring device also includes a spectrometer set in the main channel or the branch channel so that light can enter different branch channels. The light propagation path at the tuyere in the blast furnace tuyere monitoring device is affected by the spectrometer, which will affect the tuyere temperature measured by the temperature detector in the branch channel by capturing light. There is a technical problem that the working condition of the blast furnace monitored at the blast furnace tuyere is not accurate enough. The embodiment of the present application provides a blast furnace tuyere monitoring device, which can at least solve the above technical problems to a certain extent.

[0037] It should be noted that at least two branch channels are set up because the temperature sensor needs to occupy the installation space of a branch channel. The presence of the temperature sensor will block the propagation of light in the branch channel where the temperature sensor is located, making it difficult to conduct manual observation. Therefore, it is necessary to set up other branch channels for manual observation, and cooperate with the spectrometer to allow the light emitted from the air outlet to enter the required branch channel for observation or temperature measurement.

[0038] The present application will be described below with reference to the accompanying drawings:

[0039] Figure 1 FIG. 1 shows a schematic diagram of a blast furnace tuyere monitoring device in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 1 The embodiment of the present application provides a blast furnace tuyere monitoring device, which is used to be connected to a tuyere (not shown in the figure), including:

[0040] The mounting member 1 is provided with a temperature measuring channel 11 and a peephole 12 which are connected to each other and have an angle between their axes, and the temperature measuring channel 11 is connected to the air outlet.

[0041] The temperature measuring device 2 is arranged in the temperature measuring channel 11 and is used to measure the temperature of the air outlet.

[0042] The sliding member 3 can be reciprocated and inserted into or withdrawn from the temperature measuring channel 11 , and is provided with a reflecting portion 31 for reflecting the light emitted from the air outlet to the peephole 12 .

[0043] The mounting member 1 can be installed at the tuyere of a blast furnace, and the temperature measuring channel 11 in the mounting member 1 can be connected to the tuyere, so that the light emitted from the tuyere can enter the temperature measuring channel 11, and then be directly captured and measured by the thermometer 2 in the temperature measuring channel 11 to obtain the relevant temperature value of the tuyere. The thermometer 2 captures and measures the light propagating in the same temperature measuring channel 11, and the tuyere temperature value finally fed back is also relatively accurate. The mounting member 1 is connected to the temperature measuring channel 11, and a peephole 12 is provided with an axis thereof at an angle to the axis of the temperature measuring channel 11, so that the light entering the temperature measuring channel 11 from the tuyere may also enter the peephole 12 and be manually observed. The blast furnace tuyere monitoring device is also provided with a sliding member 3 which can be reciprocally inserted into or withdrawn from the temperature measuring channel 11. When manual observation is required, the sliding member 3 can be inserted into the temperature measuring channel 11. The reflecting portion 31 on the sliding member 3 can reflect the light from the tuyere outlet to the peephole 12 to complete manual observation. When manual observation is not required, the sliding member 3 can be moved to withdraw from the temperature measuring channel 11, and the light emitted from the tuyere is directly captured by the thermometer 2 without being affected by the reflecting portion 31. The temperature accuracy of the blast furnace tuyere measured by the thermometer 2 is improved, and manual observation of the tuyere can also be carried out normally. The blast furnace operating condition can be more accurately monitored through the blast furnace tuyere, which to a certain extent solves the technical problem that the operating condition of the blast furnace monitored at the blast furnace tuyere is not accurate enough.

[0044] Moreover, the blast furnace tuyere monitoring device in the present application has a simple structure, high integration, small space occupation and is easy to install. Compared with the blast furnace tuyere monitoring device with an overly complex spectroscopic structure, the reliability and convenience can also be improved.

[0045] It should be noted that it is rare to manually observe the blast furnace tuyere from the peephole 12, and the time for manual observation is also short. When the tuyere is manually observed from the peephole 12, it is also possible to judge whether the working condition of the blast furnace is in a normal state based on the observed situation. Therefore, the time and situation for the slider 3 to slide into the temperature measurement channel 11 are also short, which will not affect the normal temperature measurement of the thermometer 2. When the thermometer 2 is connected to an automation system such as a controller, the temperature value of the thermometer 2 corresponding to the manual observation time period can also be deleted, which can ensure the normal temperature measurement of the thermometer 2 and the accuracy of the measured temperature. Figure 1 The solid arrow in the figure is the propagation path of the light emitted from the vent during manual observation. Figure 1 The dotted arrow in is the propagation path of the light emitted from the air outlet when the temperature sensor 2 is measuring the temperature normally.

[0048] The sliding part 32 can be reciprocated and inserted into or withdrawn from the temperature measuring channel 11 , and the reflecting part 31 is embedded in the sliding part 32 .

[0049] The sliding part 32 can serve as a carrier of the reflecting part 31. The reflecting part 31 is embedded in the sliding part 32 to facilitate the installation of the reflecting part 31 and the sliding part 32. The reflecting part 31 can also move with the sliding part 32 to insert or withdraw the temperature measuring channel 11. When the reflecting part 31 moves with the sliding part 32 to be inserted into the temperature measuring channel 11, the direction of the light emitted from the air outlet can be changed to allow the light to enter the peephole 12 for manual observation.

[0050] In some or certain embodiments, the sliding portion 32 may be made of metal or high temperature resistant material, the reflecting portion 31 may be a plane mirror, the sliding portion 32 may be provided with a groove 34 for embedding the plane mirror, and the plane mirror may be placed in the groove 34 of the sliding portion 32 and adhered or fixedly connected to the sliding portion 32.

Part of the structure of the sliding part 32 may be located in the temperature measuring channel 11, and the insert 4 may abut against the bottom of the strip groove 33, and may also play a role in positioning the sliding part 32, facilitating manual observation. The insert 4 is separated from the mounting part 1, and the sliding part 32 may be withdrawn from the temperature measuring channel 11.

[0055] In some or certain embodiments, the insert 4 may be a fastener such as a screw, one end of the insert 4 may not extend into the temperature measuring channel 11, the strip groove 33 of the sliding portion 32 may be located outside the temperature measuring channel 11, and the insert 4 may be inserted into the strip groove 33. The movement and positioning of the sliding portion 32 relative to the mounting member 1 can also be achieved.

[0056] In some or certain embodiments, the mounting member 1 may be provided with a sliding hole 13 adapted to the shape of the sliding portion 32, the sliding hole 13 is connected to the temperature measuring channel 11, and the sliding portion 32 can be inserted into the sliding hole 13 and slide relative to the mounting member 1 to insert or withdraw the temperature measuring channel 11. The sliding portion 32 may also be a plate-like structure other than a rectangular parallelepiped, and the sliding hole 13 may be set to an adapted shape. This facilitates the movement of the sliding portion 32 relative to the mounting member 1 and the insertion of the sliding portion 32 into the temperature measuring channel 11.

[0057] In some or certain embodiments, the peephole 12 is located between the air outlet and the temperature detector 2 along the extension direction of the temperature measurement channel 11.

[0066] The mounting portion 16 is hinged with the connecting portion 14, and the blast furnace tuyere monitoring device also includes a limit rod 5 fixed with the connecting portion 14, and a rotating member 6 rotatably connected with the mounting portion 16, and the rotating member 6 is provided with a slot 61 for rotating with the rotating member 6 relative to the mounting portion 16 to be sleeved on the limit rod 5. Then, by rotating the rotating member 6 relative to the mounting portion 16, the slot 61 can be sleeved on the limit rod 5, or the slot 61 can be separated from the limit rod 5. When the mounting portion 16 is hinged with the connecting portion 14, the positioning of the mounting portion 16 relative to the connecting portion 14 can also be achieved, so as to ensure the stable use of the mounting member 1. When the slot 61 of the rotating member 6 is separated from the limit rod 5, the mounting portion 16 can be rotated relative to the connecting portion 14, so that both ends of the mounting hole 161 of the mounting portion 16 can be in an open state, so that the temperature detector 2 can be easily installed or connected to the mounting hole 161, and the maintenance and installation of the temperature detector 2 are more convenient.
