[0039] like Figure 1 As shown, according to an embodiment of the utility model, a kiln endoscopic imaging system 100, the kiln 1 has a furnace wall 11, the furnace wall 11 has an observation hole 12, and the kiln endoscopic imaging system 100 includes: a heat insulation box 2, the heat insulation box 2 is suitable for being fixed to the furnace wall 11 and defining an installation space 21, the installation space 21 is opposite to and communicates with the observation hole 12, an assembly tube 3, at least part of the assembly tube 3 is arranged in the installation space 21 and is fixed to the heat insulation box 2, and the assembly tube 3 is arranged corresponding to the observation hole 12; an image acquisition device 4, an image acquisition device 5, an image acquisition device 6, an image acquisition device 7, an image acquisition device 8, an image acquisition device 9, an image acquisition device 10, an image acquisition device 11, an image acquisition device 12, an image acquisition device 12, an image acquisition device 13, an image acquisition device 14, an image acquisition device 15, an image acquisition device 16, an image acquisition device 17, an image acquisition device 18, an image acquisition device 19, an image acquisition device 11, an image acquisition device 12, an image acquisition device 11, an image acquisition device 12, an image acquisition device 13, an image acquisition device 14, an image acquisition device 15, an image acquisition device 16, an image acquisition device 18, an image acquisition device 19 ... The acquisition device 4 has an image acquisition probe 41, which passes through the heat insulation box 2 and is assembled in the assembly tube 3. The image acquisition probe 41 is suitable for extending into the kiln 1 through the observation hole 12 to collect images in the kiln 1; the slag cleaning component 5, the slag cleaning component 5 includes a slag cleaning part 51 and a driving mechanism 52, the slag cleaning part 51 is arranged in the assembly tube 3 and is movable relative to the assembly tube 3 along the axial direction of the assembly tube 3, the driving mechanism 52 is fixed to the heat insulation box 2, and the driving mechanism 52 is connected to the slag cleaning part 51 to drive the slag cleaning part 51 to move.

[0040] The kiln 1 has a furnace wall 11, which is the peripheral wall of the kiln 1 and has a heat-insulating effect, and can also reduce the risk of waste slag flying out of the kiln 1. The furnace wall 11 is provided with an observation hole 12, which is used to timely observe the material and flame combustion inside the kiln 1, and set reasonable process parameters by monitoring the internal working conditions of the kiln 1 to improve the safety of the operation of the kiln 1. The kiln endoscopic imaging system 100 includes a heat-insulating box 2, which is arranged outside the furnace wall 11, for example: the heat-insulating box 2 is fixed to the outer peripheral wall of the furnace wall 11. The heat insulation box 2 is used for preliminary heat insulation. The heat insulation box 2 can be fixed to the furnace wall 11 by screwing. The heat insulation box 2 can also be fixed to the furnace wall 11 by riveting, but the utility model is not limited thereto. The heat insulation box 2 can also be fixed to the furnace wall 11 by other means, as long as the heat insulation box 2 is fixed to the furnace wall 11. The utility model takes the heat insulation box 2 fixed to the furnace wall 11 by screwing as an example for explanation. The heat insulation box 2 is fixed to the furnace wall 11, which is conducive to the heat insulation box 2 to play a stable heat insulation role, thereby improving the working safety of the kiln endoscopic imaging system 100. The heat insulation box 2 defines an installation space 21, which is opposite to and connected to the observation hole 12, which is conducive to the heat insulation box 2 to perform preliminary heat insulation on the heat radiated through the observation hole 12.

[0041] The kiln endoscopy imaging system 100 also includes an image acquisition device 4, which is used to acquire images. The image acquisition device 4 has an image acquisition probe 41, which is passed through the heat insulation box 2 and assembled in the assembly tube 3. The assembly tube 3 has a protective effect on the image acquisition probe 41, which is conducive to the normal and stable operation of the image acquisition probe 41. The peripheral wall of the assembly tube 3 is adapted to the peripheral wall of the image acquisition probe 41 and is slightly larger than the peripheral wall of the image acquisition probe 41, which reduces the risk of scratching the image acquisition probe 41 caused by the interference between the assembly tube 3 and the image acquisition probe 41, thereby improving the image clarity of the image acquisition probe 41. The image acquisition probe 41 can be extended into the kiln 1 through the observation hole 12 to acquire images in the kiln 1, which is conducive to further observing the material and flame combustion conditions inside the kiln 1. Reasonable process parameters are set by monitoring the internal working conditions of the kiln 1, and the safety of the operation of the kiln 1 is further improved.

[0042] The kiln endoscopic imaging system 100 also includes a slag cleaning component 5, which is used to automatically clean the waste slag in the kiln 1. The slag cleaning component 5 includes a slag cleaning piece 51 and a driving mechanism 52. The slag cleaning piece 51 is arranged in the assembly tube 3 and is movable relative to the assembly tube 3 along the axial direction of the assembly tube 3. The movement of the slag cleaning piece 51 can push the waste slag to fall off from the front end of the assembly tube 3, thereby reducing the risk of scratching the image acquisition probe 41. The driving mechanism 52 is fixed to the heat insulation box 2. The driving mechanism 52 can be fixed to the heat insulation box 2 by screwing, or by riveting, but the utility model is not limited thereto. The driving mechanism 52 can also be fixed to the heat insulation box 2 by other means. The method is fixed on the heat insulation box 2. As long as the driving mechanism 52 is fixed on the heat insulation box 2, fixing the driving mechanism 52 on the heat insulation box 2 is beneficial for the driving mechanism 52 to stably play a driving role. The driving mechanism 52 is connected to the slag cleaning part 51, and drives the slag cleaning part 51 to move to push the waste slag to fall off from the observation hole 12 and the open end of the assembly tube 3, thereby reducing the risk of waste slag adhering to the observation hole 12 and the open end of the assembly tube 3, and avoiding the situation that the observation hole 12 is blocked by slag and cannot collect the image inside the furnace, thereby achieving the effect of automatically removing the waste slag.

[0043] Specifically, the kiln 1 has a furnace wall 11, an observation hole 12 is arranged on the furnace wall 11, a heat insulation box 2 is arranged around the observation hole 12 and plays a heat insulation role for the observation hole 12, the heat insulation box 2 is fixed to the furnace wall 11 and defines an installation space 21, the installation space 21 is opposite to and communicates with the observation hole 12, and the risk of excessive heat radiated from the observation hole 12 is reduced, thereby improving the working safety of the kiln endoscopic imaging system 100. Part of the assembly tube 3 is arranged in the installation space 21 and is fixed to the heat insulation box 2, the image acquisition probe 41 can extend into the kiln 1 through the observation hole 12 to collect images in the kiln 1, and the image acquisition probe 41 is assembled in the assembly tube 3, and the assembly tube 3 can reduce the risk of the image acquisition probe 41 being scratched by waste residue, thereby improving the clarity of the image. The slag cleaning assembly 5 includes a slag cleaning piece 51 and a driving mechanism 52. The slag cleaning piece 51 is assembled in the assembly tube 3 and is movable relative to the assembly tube 3 along the axial direction of the assembly tube 3. The driving mechanism 52 is fixed to the heat insulation box 2 to improve the stability of the driving mechanism 52, which is beneficial for the driving mechanism 52 to continuously drive the slag cleaning piece 51 to move, and further beneficial for the slag cleaning piece 51 to continuously play a slag cleaning role.

[0044] Therefore, by setting up the slag cleaning component 5 to automatically remove the waste slag, the risk of waste slag adhering to the observation hole 12 and the open end of the assembly tube 3, causing the observation hole 12 to be blocked and unable to collect images inside the furnace, is reduced, the clarity of the image is improved, and the probe can be better protected. The self-protection ability of the kiln endoscopic imaging system 100 in harsh working conditions is improved, which is beneficial to the continuous and stable operation of the image acquisition probe 41.

[0045] It is understandable that in the related art, waste slag is easily attached to the observation hole, so that the observation hole is filled with waste slag, resulting in frequent blockage of the observation hole, making it impossible for the conventional kiln endoscopy imaging system to capture images inside the furnace.

[0046] According to the kiln endoscopic imaging system 100 of the embodiment of the utility model, the movement of the slag cleaning part 51 can push the waste slag to fall off from the observation hole 12 and the open end of the assembly tube 3, so as to reliably clean the waste slag blocking the image acquisition probe 41, and avoid the waste slag blocking the observation hole 12 and affecting the image acquisition probe 41 to collect the image inside the furnace. At the same time, since the image acquisition probe 41 is assembled in the assembly tube 3, the assembly tube 3 can block the waste slag that falls or collapses from the observation hole 12 caused by the action of the slag cleaning part 51 on the outside of the image acquisition probe 41, so as to avoid the waste slag that falls or collapses from the observation hole 12 after the slag cleaning part 51 is actuated each time and blocks the image acquisition probe 41 again, which is beneficial to reduce the number of actions of the slag cleaning part 51 and reduce the risk of the image acquisition probe 41 being scratched by the waste slag.

[0047] In some embodiments of the present invention, Figure 1 As shown, one end of the assembly tube 3 extends into the observation hole 12 , and the other end of the assembly tube 3 is fixed to the insulation box 2 .

[0048] Among them, one end of the assembly tube 3 extends into the observation hole 12, and the end of the assembly tube 3 faces the material and flame burning inside the kiln 1, which is conducive to the image acquisition probe 41 in the assembly tube 3 to accurately capture images, and then set reasonable process parameters according to the monitored internal working conditions of the kiln 1 to improve the stability and safety of the operation of the kiln 1. The other end of the assembly tube 3 is fixed to the insulation box 2. The assembly tube 3 can be fixed to the insulation box 2 by screwing, and the assembly tube 3 can also be fixed to the insulation box 2 by riveting, but the utility model is not limited to this. The assembly tube 3 can also be fixed to the insulation box 2 by other means, as long as the assembly tube 3 is fixed to the insulation box 2. The assembly tube 3 is fixed to the insulation box 2, which is conducive to improving the stability of the assembly tube 3, and then improving the working stability of the image acquisition probe 41 in the assembly tube 3, thereby improving the clarity of the image captured by the image acquisition probe 41.

[0049] In some embodiments of the present invention, Figure 1 As shown, the slag cleaning member 51 is constructed as a cylindrical structure, and the cylindrical structure is sleeved on the outside of the image acquisition probe 41.

[0050] Among them, the slag cleaning piece 51 is constructed as a cylindrical structure, and the structural shape of the slag cleaning piece 51 is adapted to the outer peripheral wall of the assembly tube 3 and the outer peripheral wall shape of the image acquisition probe 41, and the outer peripheral wall size of the slag cleaning piece 51 is slightly larger than the outer peripheral wall size of the image acquisition probe 41, and slightly smaller than the inner peripheral wall size of the assembly tube 3. Such a setting is conducive to the cylindrical structure of the slag cleaning piece 51 being sleeved on the outside of the image acquisition probe 41 and assembled between the image acquisition probe 41 and the assembly tube 3, which is conducive to the slag cleaning piece 51 effectively cleaning the waste slag between the image acquisition probe 41 and the assembly tube 3, and improving the image clarity collected by the image acquisition probe 41. For some severe working conditions of the kiln 1, the slag cleaning piece 51 can also clean the waste slag attached to the observation hole 12, reducing the risk of being unable to collect images in the furnace due to blockage of the observation hole 12.

[0051] In some embodiments of the present invention, Figure 1 As shown, the driving mechanism 52 includes: a first driving member 521 and an adapter 522 , the first driving member 521 is fixed to the heat insulation box 2 , and the adapter 522 is connected between the first driving member 521 and the slag cleaning member 51 .

[0052] Among them, the driving mechanism 52 includes a first driving member 521 and an adapter 522, and the first driving member 521 can be a cylinder structure or a hydraulic cylinder. The first driving member 521 is used to drive the slag cleaning member 51 to move relative to the assembly tube 3 along the axial direction of the assembly tube 3 to clean the waste residue between the image acquisition probe 41 and the assembly tube 3. The first driving member 521 is fixed to the heat insulation box 2, and the first driving member 521 can be fixed to the heat insulation box 2 by screw connection. The first driving member 521 can also be fixed to the heat insulation box 2 by riveting, but the utility model is not limited to this. The first driving member 521 can also be fixed to the heat insulation box 2 by other means, as long as the first driving member 521 is fixed to the heat insulation box 2, the first driving member 521 is fixed to the heat insulation box 2, which is conducive to improving the working stability of the first driving member 521, thereby enabling the first driving member 521 to stably play a driving role. The adapter 522 is connected between the first driving member 521 and the slag cleaning member 51, and the adapter 522 can be connected to the first driving member 521 by thread. The first driving member 521 can drive the slag cleaning member 51 to move through the adapter 522. Specifically, the first driving member 521 drives the adapter 522 to move, thereby driving the slag cleaning member 51 to move relative to the assembly tube 3 along the axial direction of the assembly tube 3, which is conducive to cleaning the waste slag between the image acquisition probe 41 and the assembly tube 3, and further improving the image clarity collected by the image acquisition probe 41. For some severe working conditions of the kiln 1, the first driving member 521 can further drive the slag cleaning member 51 to continue to move toward the inside of the kiln 1, clean the waste slag attached to the observation hole 12, and further reduce the risk of failing to collect images in the furnace due to blockage of the observation hole 12.

[0053] In some embodiments of the present invention, Figure 1and Figure 2 As shown, the side wall of the assembly cylinder 3 has an avoidance hole 31 , the avoidance hole 31 extends along the axial direction of the assembly cylinder 3 , and the adapter 522 is penetrated through the avoidance hole 31 .

[0054] The side wall of the assembly tube 3 has an avoidance hole 31, which is used to avoid the adapter 522, thereby reducing the risk of interference between the adapter 522 and the assembly tube 3. The avoidance hole 31 extends along the axial direction of the assembly tube 3, and the adapter 522 is arranged in the avoidance hole 31 and is fixedly connected to the slag cleaning member 51. The adapter 522 can be connected to the slag cleaning member 51 by screwing, or by riveting, but the utility model is not limited thereto. The adapter 522 can also be connected to the slag cleaning member 51 by other means, as long as the adapter 522 is fixedly connected to the slag cleaning member 51. When the first driving member 521 drives the adapter 522 to move, the adapter 522 moves along the axial direction of the assembly tube 3, thereby driving the slag cleaning member 51 to move relative to the assembly tube 3 along the axial direction of the assembly tube 3, which is beneficial to cleaning the waste residue between the image acquisition probe 41 and the assembly tube 3, and further improving the image clarity acquired by the image acquisition probe 41.

[0055] In some embodiments of the present invention, Figure 1 As shown, the first driving member 521 can be a driving cylinder.

[0056] Among them, the first driving member 521 can be a driving cylinder, which is a power device. In the utility model, the first driving member 521 uses gas pressure to drive the adapter 522 to move along the axial direction of the assembly tube 3, and then drives the slag cleaning member 51 to move along the axial direction of the assembly tube 3 relative to the assembly tube 3. The first driving member 521 is connected to the electrical control device, and the automatic electrical control device is used to achieve the effect of automatic cleaning of waste slag, which is beneficial to the continuity of automatic cleaning of waste slag, and further beneficial to the continuous and stable operation of the kiln endoscopy imaging system 100.

[0057] In some embodiments of the present invention, Figure 1 As shown, the image acquisition device 4 also has a second driving member 42, which is fixed to the heat insulation box 2 and connected to the image acquisition probe 41. The second driving member 42 is used to drive the image acquisition probe 41 to move relative to the assembly tube 3 along the axial direction of the assembly tube 3, so that the image acquisition probe 41 can reciprocate along the axial direction of the assembly tube 3.

[0058] Among them, the image acquisition device 4 also has a second driving member 42, and the second driving member 42 can also be set as a driving cylinder. The second driving member 42 is fixed to the heat insulation box 2. The second driving member 42 can be fixed to the heat insulation box 2 by screwing. The second driving member 42 can also be fixed to the heat insulation box 2 by riveting, but the utility model is not limited to this. The second driving member 42 can also be fixed to the heat insulation box 2 by other means. As long as the second driving member 42 is fixed to the heat insulation box 2, the second driving member 42 is fixed to the heat insulation box 2, which is conducive to improving the working stability of the second driving member 42, thereby enabling the second driving member 42 to stably play a driving role. The second driving member 42 and the heat insulation box 2 can be designed at a certain inclination angle, and the size of the inclination angle can be selected according to the monitoring target, which is conducive to more clear observation of the monitoring target.

[0059] The second driving member 42 is connected to the image acquisition probe 41. The image acquisition probe 41 can be hung on the second driving member 42. The second driving member 42 can drive the image acquisition probe 41 to move relative to the assembly tube 3 along the axial direction of the assembly tube 3, so that the image acquisition probe 41 can reciprocate along the axial direction of the assembly tube 3, thereby facilitating the image acquisition probe 41 to penetrate into the kiln 1 through the observation hole 12, further observe the material and flame combustion inside the kiln 1, set reasonable process parameters through the monitored internal working conditions of the kiln 1, and further improve the safety of the operation of the kiln 1. It is also beneficial for the image acquisition probe 41 to withdraw from the kiln 1, reduce the risk of damage to the image acquisition probe 41 due to continuous operation under high temperature conditions in the kiln 1, and thus improve the working safety of the image acquisition probe 41.

[0060] In some embodiments of the present invention, Figure 1 As shown, the second driving member 42 has a moving portion 421 , and the moving portion 421 is fixedly connected to the image acquisition probe 41 .

[0061] The second driving member 42 has a moving part 421, and the second driving member 42 can drive the moving part 421 to move relative to the assembly tube 3 along the axial direction of the assembly tube 3. The moving part 421 is fixedly connected to the image acquisition probe 41. Specifically, the moving part 421 can be set as an annular structure, and the moving part 421 is sleeved on the peripheral wall of the image acquisition probe 41 and clamped by bolts, so as to reduce the relative movement of the moving part 421 and the image acquisition probe 41 caused by the unstable assembly of the moving part 421, thereby reducing the risk of the image acquisition probe 41 falling off from the moving part 421. When the second driving member 42 drives the moving part 421, it drives the image acquisition probe 41 to move relative to the assembly tube 3 along the axial direction of the assembly tube 3, thereby facilitating the image acquisition probe 41 to extend into the kiln 1 through the observation hole 12, further observe the material and flame combustion inside the kiln 1, set reasonable process parameters by monitoring the internal working conditions of the kiln 1, and further improve the safety of the operation of the kiln 1.

[0062] In some embodiments of the present invention, Figure 1 As shown, the image acquisition probe 41 includes: a protective tube 411, a camera, a lens and a filter. The camera, the lens and the filter are all arranged in the protective tube 411, the filter is located between the camera and the lens, and the protective tube 411 is fixedly connected to the second driving member 42.

[0063] Among them, the image acquisition probe 41 includes a protective tube 411, a camera, a lens and a filter. The camera, the lens and the filter are all arranged in the protective tube 411. The protective tube 411 can protect the safe operation of the camera, the lens and the filter, reduce the risk of scratching the camera, the lens and the filter, and further improve the working safety of the image acquisition probe 41. The filter is located between the camera and the lens, so that the image acquisition probe 41 has a certain ability to penetrate flying sand, and can clearly see the material morphology and flame combustion conditions in the kiln 1 in a harsh environment, further improving the safety of the operation of the kiln 1. The protective tube 411 is fixedly connected to the second driving member 42, and the protective tube 411 can be welded to the end plate of the second driving member 42, which is beneficial to the stability of the protective tube 411, thereby better protecting the camera, the lens and the filter, reducing the risk of scratching the camera, the lens and the filter, and further improving the clarity of the image collected by the image acquisition probe 41.

[0064] Furthermore, the hardware of the image acquisition probe 41 can select cameras and lenses with longer wavelengths, including but not limited to 3-5um band and 8-14um band cameras. Filters can be used to further determine the best monitoring band for dust penetration, and then cameras and lenses with appropriate bands can be selected according to different working conditions of the kiln 1, thereby further improving the clarity of the images captured by the image acquisition probe 41.

[0065] In some embodiments of the present invention, Figure 1 As shown, a cooling medium is introduced into the thermal insulation box 2 and / or the image acquisition probe 41 .

[0066] Among them, the cooling medium is introduced into the heat insulation box 2, or the cooling medium is introduced into the image acquisition probe 41, or the cooling medium is introduced into both the heat insulation box 2 and the image acquisition probe 41. The utility model takes the cooling medium introduced into both the heat insulation box 2 and the image acquisition probe 41 as an example for explanation. The introduction of the cooling medium into the heat insulation box 2 is conducive to reducing the heat of the first driving member 521 and the second driving member 42, improving the working safety of the first driving member 521 and the second driving member 42, and thus ensuring the working reliability of the kiln endoscopic imaging system 100. The introduction of the cooling medium into the image acquisition probe 41 can reduce the temperature of the protective tube 411, the camera, the lens and the filter, reduce the risk of failure of the protective tube 411, the camera, the lens and the filter due to excessive temperature, and protect the protective tube 411, the camera, the lens and the filter to operate stably at high temperature for a long time, thereby further improving the working reliability of the kiln endoscopic imaging system 100.

[0067] It should be noted that the kiln endoscopy imaging system 100 can be divided into three parts: an image acquisition device 4, an electrical control device and a computer. The electrical control device includes a power supply module, a temperature and pressure monitoring module, a timing control module, a data transceiver module, a first solenoid valve and a second solenoid valve.

[0068] The first solenoid valve can receive information from the power module and the temperature and pressure monitoring module, and control the second driving member 42 according to the received information. The first solenoid valve can control the pneumatic transmission of the second driving member 42 to control the image acquisition probe 41 to advance from the observation hole 12 or withdraw from the kiln 1. Specifically, when the temperature and pressure monitoring module detects that the air pressure is insufficient or the probe temperature is over-temperature, and when the power module detects that the power is off, the first solenoid valve is controlled to operate to drive the second driving member 42 to work, thereby controlling the image acquisition probe 41 to withdraw from the kiln 1 and retract into the assembly tube 3 to protect the working safety of the image acquisition probe 41 and reduce the risk of damage to the image acquisition probe 41.

[0069] The timing control module drives the first driving member 521 to work regularly through the second solenoid valve. The first driving member 521 drives the slag cleaning member 51 to extend and retract to automatically remove the waste slag at the front end of the assembly tube 3, thereby achieving the effect of automatically removing waste slag by the kiln endoscopic imaging system 100.

[0070] The computer carries an image processing module and an image display module. The image processing module can enhance and pseudo-color the image collected by the image acquisition probe 41, so that the image clarity is significantly improved, thereby improving the final image effect, and making it easier for users to see the situation inside the furnace. The image display module can finally display the processed image to the user, and the user can set reasonable process parameters based on the working conditions displayed by the image, thereby further improving the safety of the operation of the kiln 1.

[0071] Specifically, first, the assembly tube 3 is installed on the inner wall of the heat insulation box 2, and the image acquisition probe 41 is retracted inside the assembly tube 3 for protection when working normally, so the slag will be formed at the front end of the assembly tube 3;

[0072] Secondly, the timing control module in the electrical control device drives the first driving member 521 to operate in a timed manner through the second solenoid valve, thereby driving the slag cleaning member 51 to extend and retract to automatically remove the waste slag at the front end of the assembly cylinder 3 .

[0073] Finally, the timed action of the slag cleaning assembly 5 and the protective effect of the assembly tube 3 on the probe can ensure that the image acquisition probe 41 operates normally and stably in the furnace.
