[0034] According to the utility model, a kiln atmosphere monitoring device is provided, such as Figures 1 to 3 As shown, the kiln atmosphere monitoring device in this embodiment includes a main body 2, a fixing component sleeved on the outer side of the main body 2, and a detection component connected to the main body 2. Hereinafter, the specific structure of the above-mentioned parts of the kiln atmosphere monitoring device according to the utility model will be described in detail.

[0035] In this embodiment, if Figure 1 As shown, the main body 2 is formed into a long strip structure corresponding to the exhaust port 11 of the kiln 1, and the two ends of the length direction are respectively formed as a detection end and an outlet end, so that the detection end of the main body 2 can extend to the inside of the kiln 1 through the exhaust port 11, and the gas in the kiln 1 is discharged from the outlet end, so as to directly detect the atmosphere, pressure and temperature inside the kiln 1, thereby effectively ensuring the intuitiveness and accuracy of the monitoring results of the monitoring device. Specifically, the interior of the main body 2 is formed into a cavity structure, and the detection end and the outlet end are respectively formed with a detection port 21 and an outlet 22 that connect the internal cavity of the kiln 1 with the external space.

[0036] It should be noted that there are no specific restrictions on the shape and length of the main body 2. For example, in this embodiment, the exhaust port 11 of the kiln 1 is formed into a cylindrical structure, and the main body 2 is also formed into a quasi-cylindrical structure accordingly, as long as it is convenient for the monitoring work of the main body 2 and can ensure the stability of the monitoring of the main body 2 and the accuracy of the monitoring results. In addition, the specific shape, size and position of the detection port 21 and the guide port 22 are not fixed, as long as the above-mentioned technical effects can be achieved.

[0037] In this embodiment, the main body 2 is movably connected to the exhaust port 11 of the kiln 1, so that the position of the detection end extending into the kiln 1 can be flexibly adjusted, that is, the device can have multiple sampling points inside the kiln 1, thereby ensuring the accuracy of the monitoring results of the device. When the main body 2 is moved to a preset position, it can be fixed relative to the main body 2 by a fixing component to facilitate sampling of the main body 2 and detection of the detection component.

[0038] Specifically, Figures 1 to 3 As shown, the fixing assembly in this embodiment includes a movable hoop 4 sleeved on the outer side of the main body 2, which is formed into a columnar structure similar to the main body 2 and the interior of the movable hoop 4 is also formed into a cavity structure. Further, along the length direction of the main body 2, the first end of the movable hoop 4 close to the detection end is formed with a first connection hole 41, and the second end of the movable hoop 4 close to the lead-out end is formed with a second connection hole 42; further, the first connection hole 41 and the second connection hole 42 are both connected to the internal cavity of the movable hoop 4, and the inner diameter of the first connection hole 41 is adapted to the outer diameter of the exhaust port 11, and the inner diameter of the second connection hole 42 is adapted to the outer diameter of the main body 2, so as to ensure the stability of the overall structure of the monitoring device and the stability of its connection with the kiln 1, and in order to facilitate the movement of the movable hoop 4 relative to the main body 2, the first connection hole 41 and the exhaust port 11, and the second connection hole 42 and the main body 2 are all clearance-matched.

[0039] More specifically, if Figure 2 As shown, the outer wall of the movable hoop 4 is also formed with an opening 43 (actually a slit structure), and the opening 43 is connected to the interior of the movable hoop 4 and its two ends in the length direction respectively penetrate the first connecting hole 41 and the second connecting hole 42, so that the movable hoop 4 is formed into a C-shaped structure. In addition, along the length direction of the main body 2, the first end and the second end of the movable hoop 4 are respectively provided with a first locking hole 44 and a second locking hole 45, and the first locking hole 44 and the second locking hole 45 both penetrate the two ends in the height direction of the movable hoop 4, and both of them also penetrate the above-mentioned opening 43. Correspondingly, the fixing assembly also includes a screw 46 correspondingly connected to the first locking hole 44 and the second locking hole 45, and each screw 46 is provided with at least two locking nuts 47, and the two locking nuts 47 are respectively abutted against the two ends in the height direction of the movable hoop 4.

[0040] When the main body 2 moves to the preset position, the movable hoop 4 is also moved to the corresponding position, and then the movable hoop 4 is locked with the main body 2 and the exhaust port 11 by using the locking nut 47, that is, the first connecting hole 41 and the exhaust port 11 and the second connecting hole 42 and the main body 2 become interference fit. When the sampling point of the main body 2 needs to be changed, just loosen the locking nut 47. In order to achieve the above technical effects, the movable hoop 4 should be made of a material with a certain elasticity (such as plastic, etc.) to facilitate the opening and closing of the opening 43; in addition, the first locking hole 44 and the second locking hole 45 in this embodiment are formed as smooth through holes, and the two are clearance-fitted with the screw 46 to avoid wear on the screw 46 when the opening 43 is opened and closed; further, the locking nut 47 should be able to completely cover the first locking hole 44 and the second locking hole 45 to ensure the above locking effect.

[0041] However, the present invention is not limited thereto, and existing components such as clamps may also be used to realize the movable connection between the main body 2 and the kiln 1 .

[0042] In this embodiment, if Figure 1 As shown, the detection component is connected to the outlet 22 through an air duct, including a furnace pressure gauge 32 (for detecting pressure), an atmosphere analyzer 33 (for analyzing gas composition) and an exhaust fan 34 connected in sequence, and the three are connected through the air duct. In addition, the air duct out of the outlet 22 is also provided with an exhaust valve 35 to control the amount and time of gas extraction. Although not shown in the figure, the furnace pressure gauge 32 and the atmosphere analyzer 33 are both connected to the display screen for communication or electrical connection, so that the detection results can be displayed in real time. It should be noted that the interior of the kiln 1 may be positive pressure or negative pressure. When the interior of the kiln 1 is in a positive pressure state, after the exhaust valve 35 is opened, the gas will automatically be introduced into the furnace pressure gauge 32 and the atmosphere analyzer 33, that is, the monitoring personnel can see the monitoring results on the display screen; when the interior of the kiln 1 is in a negative pressure state, after the exhaust valve 35 is opened, the furnace pressure gauge 32 and the atmosphere analyzer 33 have no response, and the exhaust fan 34 can be used to extract the gas inside the kiln 1 for easy detection.

[0043] In addition, in this embodiment, a thermocouple 31 is also provided inside the main body 2, and the first end of the thermocouple 31 in the length direction extends to the detection port 21, and the second end of the thermocouple 31 in the length direction (through the corresponding through hole) passes through to the outside of the main body 2. The thermocouple 31 is also communicatively connected or electrically connected to the display screen to realize the detection of the internal temperature of the kiln 1.

[0044] According to the kiln atmosphere monitoring device of the utility model, the main body 2 is formed with a detection end and an outlet end, and the detection end can extend to the inside of the kiln 1 through the exhaust port 11 of the kiln 1 and discharge the gas in the kiln 1 from the outlet end, and then introduce the gas into the detection component, so as to more accurately monitor and judge the atmosphere composition and reaction conditions inside the kiln 1; in addition, the main body 2 of the monitoring device is movably connected with the exhaust port 11 of the kiln 1, so that the main body 2 can be flexibly moved to multiple positions inside the kiln 1, and then fixed to the kiln 1 through the fixing component. In this way, the sampling point of the monitoring device can be as close to the center of the kiln 1 as possible and the number of sampling points is large, so that the atmosphere composition and reaction conditions inside the kiln 1 can be monitored and judged more directly and accurately, and then the furnace state of the kiln 1 can be more effectively monitored, that is, the real reaction conditions inside the kiln 1 can be reflected intuitively and efficiently.

[0045] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
