Description

Technical Field

[0001] The utility model relates to the technical field of boiler furnace flame monitoring, in particular to a furnace flame camera with high temperature resistance and corrosion resistance. Background Technique

[0002] The flame signal is transmitted to the camera through the optical system, converted into an electrical signal by the camera and sent to the monitor screen in the control room, so that the monitoring personnel can clearly understand the real scene of the flame combustion in the furnace and make corresponding combustion adjustments. Therefore, when the boiler is ignited, operating at low load or a fault endangering the normal operation of the boiler occurs, this system helps to prevent the boiler furnace from extinguishing and is an indispensable device for ensuring the safe and economic operation of the boiler.

[0003] The working temperature of the furnace flame camera is relatively high, so an independent cooling system needs to be equipped. Some furnace flame cameras are configured with an air cooling system. Heat exchange is carried out between the air and the outer protective shell of the furnace flame camera, and then the hot air flows to the cooling device, and then flows to the outer protective shell of the flame camera through the air circulation device for heat exchange, so as to dissipate heat in a cycle.

[0004] Due to the special working environment of the flame camera, ashes will float and adhere to the outer side of the camera protective shell. Especially the protective cover plate in front of the lens is transparent. The adhesion of ashes will reduce the field of view of the camera, making it inconvenient for the staff to observe the flame in the furnace comprehensively. The special environment also makes it inconvenient for the staff to clean manually. Content of the Utility Model

[0005] In view of the above problems, the present application provides a furnace flame camera with high temperature resistance and corrosion resistance, which solves the problem that due to the special working environment of the flame camera, ashes will float and adhere to the outer side of the camera protective shell. Especially the protective cover plate in front of the lens is transparent. The adhesion of ashes will reduce the field of view of the camera, making it inconvenient for the staff to observe the flame in the furnace comprehensively. The special environment also makes it inconvenient for the staff to clean manually.

[0006] A furnace flame camera with high temperature resistance and corrosion resistance includes a camera device. A heat dissipation sleeve is fixedly installed on the outside of the camera device. A plurality of heat exchange channels are opened inside the heat dissipation sleeve. A transparent cover plate is fixedly installed at one end of the heat dissipation sleeve close to the imaging end of the camera device. In the heat exchange channel closest to the transparent cover plate, a plurality of force-boosting plates are installed in the middle. The force-boosting plates are connected to the fan blades through a transmission mechanism, and the blowing direction of the fan blades faces the transparent cover plate.

[0007] Further, a sealing cover is fixedly installed and communicated with the outside of the heat dissipation sleeve. The transmission mechanism includes a driving rotating shaft, which is installed in the middle of the sealing cover. The force - borrowing plates are evenly and fixedly installed on the outside of the driving rotating shaft, and the driving rotating shaft rotates through one side of the sealing cover.

[0008] Further, a first fixing block is rotatably installed on the outside of the driving rotating shaft, and the first fixing block is fixedly installed on the outside of the heat dissipation sleeve.

[0009] Further, the transmission mechanism further includes a driving bevel gear, which is fixedly installed at the end of the driving rotating shaft. A driven bevel gear is meshed and installed on the outside of the driving bevel gear. A driven rotating shaft is fixedly installed on the outside of the driven bevel gear, and the fan blades are evenly and fixedly installed on the outside of the driven rotating shaft.

[0010] Further, a second fixing block is rotatably installed on the outside of the driven rotating shaft, and the second fixing block is fixedly installed on the outside of the heat dissipation sleeve.

[0011] Further, an air inlet pipe and a return pipe are fixedly installed on the outside of the heat dissipation sleeve. Both the air inlet pipe and the return pipe are communicated with the heat exchange channel. The air inlet pipe is communicated with an external air circulation device, and the return pipe is communicated with an external cooling device.

[0012] The beneficial effects of the present utility model are as follows:

[0013] For the high - temperature and corrosion - resistant furnace flame camera of the present utility model, an air - circulation heat dissipation method is adopted to dissipate heat from the imaging device. Different from the prior art, during the air - flow heat - exchange process, the force - borrowing plates are driven to rotate, and then the fan blades are driven to rotate through the transmission mechanism and blow towards the transparent cover plate, blowing off the ash adhered to the outside of the transparent cover plate, ensuring the cleanliness of the outside of the transparent cover plate. Furthermore, the imaging device can clearly and completely transmit the furnace flame condition to the console, facilitating the remote viewing by the staff. Description of the Drawings

It should be noted here that the description of these embodiment modes is used to help understand the present utility model, but does not constitute a limitation to the present utility model

[0022] Embodiment 1:

[0023] As Figures 1-5 shown, the embodiment of the present utility model provides a high-temperature and corrosion-resistant furnace flame camera, including an imaging device 2. A heat dissipation sleeve 1 is fixedly installed outside the imaging device 2. A connecting plate with good thermal conductivity can be fixedly connected between the heat dissipation sleeve 1 and the imaging device 2, so as to better dissipate heat from the imaging device 2. A plurality of heat exchange channels 6 are opened inside the heat dissipation sleeve 1. One end of the heat dissipation sleeve 1 close to the imaging end of the imaging device 2 is fixedly installed with a transparent cover plate 3, which is used for the imaging device 2 to collect data on the flame condition in the furnace, has a certain heat insulation ability, and can also play a certain protective role for the imaging device 2

[0024] Specifically, an intake pipe 4 and a return pipe 5 are fixedly installed outside the heat dissipation sleeve 1. Both the intake pipe 4 and the return pipe 5 are communicated with the heat exchange channel 6. The intake pipe 4 is communicated with an external air circulation device, and the return pipe 5 is communicated with an external cooling device

[0025] In this embodiment, the air circulation device blows the cooled air through the intake pipe 4 into the heat exchange channel 6. After heat exchange with the heat dissipation sleeve 1, it flows from the return pipe 5 to the cooling device, and then enters the air circulation device again. In this way, the heat dissipation sleeve 1 and the imaging device 2 are cooled

[0026] Embodiment 2:

[0027] The difference from the above embodiment is that in the heat exchange channel 6 closest to the transparent cover plate 3, a plurality of force - assisting plates 8 are installed in the middle. The force - assisting plates 8 are connected to the fan blades 15 through a transmission mechanism, and the blowing direction of the fan blades 15 faces the transparent cover plate 3.

[0028] Specifically, a sealing cover 7 is fixedly installed on the outside of the heat dissipation sleeve 1 in a communicating manner. The transmission mechanism includes a driving rotating shaft 9. The driving rotating shaft 9 is installed in the middle of the sealing cover 7. The force - assisting plates 8 are evenly fixedly installed on the outside of the driving rotating shaft 9, and the driving rotating shaft 9 rotatably penetrates through one side of the sealing cover 7.

[0029] Specifically, the transmission mechanism further includes a driving bevel gear 11. The driving bevel gear 11 is fixedly installed at the end of the driving rotating shaft 9. A driven bevel gear 12 is meshed and installed on the outside of the driving bevel gear 11. A driven rotating shaft 13 is fixedly installed on the outside of the driven bevel gear 12. The fan blades 15 are evenly fixedly installed on the outside of the driven rotating shaft 13.

[0030] In this embodiment, during the air - flow heat - exchange process, the force - assisting plates 8 and the driving rotating shaft 9 are driven to rotate, and then the fan blades 15 are driven to rotate through the driving bevel gear 11, the driven bevel gear 12, and the driven rotating shaft 13. The fan blades blow towards the transparent cover plate 3, blowing off the ash adhered to the outside of the transparent cover plate 3, ensuring the cleanliness of the outside of the transparent cover plate 3. Furthermore, the imaging device 2 can clearly and completely transmit the furnace flame condition to the console, facilitating remote viewing by the staff.

[0031] Specifically, a first fixing block 10 is rotatably installed on the outside of the driving rotating shaft 9 to make the rotation of the driving rotating shaft 9 more stable. The first fixing block 10 is fixedly installed on the outside of the heat dissipation sleeve 1. A second fixing block 14 is rotatably installed on the outside of the driven rotating shaft 13 to make the rotation of the driven rotating shaft 13 more stable. The second fixing block 14 is fixedly installed on the outside of the heat dissipation sleeve 1.

[0032] Specific working mode:

[0033] The air circulation device blows the cooled air through the air inlet pipe 4 towards the heat exchange channel 6. After heat - exchanging with the heat dissipation sleeve 1, it flows from the return pipe 5 to the cooling device, and then enters the air circulation device again. In this way, the heat dissipation sleeve 1 and the imaging device 2 are cooled.

[0034] During the air - flow heat - exchange process, the force - assisting plates 8 and the driving rotating shaft 9 are driven to rotate, and then the fan blades 15 are driven to rotate through the driving bevel gear 11, the driven bevel gear 12, and the driven rotating shaft 13. The fan blades blow towards the transparent cover plate 3, blowing off the ash adhered to the outside of the transparent cover plate 3, ensuring the cleanliness of the outside of the transparent cover plate 3. Furthermore, the imaging device 2 can clearly and completely transmit the furnace flame condition to the console, facilitating remote viewing by the staff.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the protection scope of the present utility model.
