Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of carbon preparation, and in particular relates to an observation device for a carbon roasting combustion control system. Background Art
[0002] The carbon roasting combustion control system is a key equipment in the carbon block roasting process, and its main function is to ensure that the quality of the roasted blocks meets the process requirements. During the entire roasting process, it is very important to monitor the temperature (1150℃) and the anode temperature (1050℃) in the carbon block fire channel, which not only ensures the quality of the roasted blocks, but also ensures the safety of the production process. Among them, the smoke exhaust rack, as an important part of the carbon roasting combustion control system, is not limited to providing negative pressure and detecting temperature, but also includes controlling the negative pressure in the fire channel by adjusting the valve to adjust the flame temperature. At present, the existing smoke exhaust rack temperature detection device adjusts the flame temperature by adjusting the main pipe and branch pipe valves to control the negative pressure in the fire channel, thereby ensuring that the heating rate of the roasting furnace fire channel meets the set process heating curve, and avoiding the smoke exhaust rack temperature from being too high, resulting in overheating and fire accidents in the furnace bottom annular flue and purification system.
[0003] At present, the smoke exhaust rack temperature detection device currently in operation in our factory is only a thermocouple installed at the elbow of the main pipe. The surface of the thermocouple contacts the smoke in the main pipe of the smoke exhaust rack, and the temperature is fed back to the control system display screen and the upper computer screen in the central control room. Since the smoke and dust passing through the inside of the smoke exhaust rack have strong adhesion, they will adhere to the surface of the thermocouple over time and affect the detection accuracy. The high-speed flow of smoke will also affect the accuracy of the thermocouple feedback. When the thermocouple shows that the temperature of the smoke exhaust rack is abnormal, the original observation port at the end of the smoke exhaust rack needs to be opened to view the inside, but the observation port is strictly prohibited to be opened at high temperatures to avoid fire or flash explosion accidents after oxygen enters. Utility Model Content

[0007] Furthermore, the observation device also includes: a sealing member; the sealing member is flexible, and when the fire-resistant glass plate is embedded in the observation channel, the sealing member is clamped between the upper area and the fire-resistant glass plate.
[0008] Furthermore, the observation device also includes a pressing piece; the pressing piece is detachably arranged in the lower layer area, and the end of the pressing piece is against the fire-resistant glass plate.

[0015] Figure 1The present invention is a schematic diagram of the cross-sectional structure of an observation device for a carbon roasting combustion control system according to an embodiment of the present invention.
[0016] Reference Figure 1 The utility model is arranged on the observation port 11 of the smoke exhaust rack 1 so that the operator can observe the inside of the smoke exhaust rack 1, wherein an observation window 2 coaxial with the observation port 11 is detachably arranged on the outer periphery of the observation port 11, and an observation channel 21 connected with the smoke exhaust rack 1 is arranged in the observation window 2. The observation channel 21 is coaxial with the observation port 11, and a fire-resistant glass plate 3 is embedded in the observation channel 21 to close the entire observation channel 21.
[0017] Specifically, the space of the observation channel 21 includes an upper area 211 and a lower area 212. The upper area 211 is located at one end close to the observation port 11, and the lower area 212 is located at one end away from the observation port 11. One end of the upper area 211 is detachably fixedly connected to the observation port 11, and the other end of the upper area 211 is fixedly connected to one end of the lower area 212. The observation channel 21 is a variable diameter structure, the upper area 211 and the lower area 212 are coaxial, and the diameter of the lower area 212 is smaller than the diameter of the upper area 211.
[0018] In order to further strengthen the stability of the fire-resistant glass plate 3 at the observation window, in another embodiment of the present application, the observation device further includes a pressing member 5 provided in the lower layer area 212. The pressing member 5 is in an annular shape as a whole, and matches the inner wall of the lower layer area 212 of the observation channel 21. The end of the pressing member 5 abuts against the fire-resistant glass plate 3, and after the pressing member 5 is fixed to the observation channel 21, the fire-resistant glass plate 3 is clamped between the observation window 2 and the pressing member 5. The fire-resistant glass plate 3 is a plate-like structure made of fire-resistant glass, and its surface is transparent and has strong high temperature resistance.
[0019] In this embodiment, the pressing member 5 and the observation channel 21 are detachably fixedly connected by threads. In order to prevent the fire-resistant glass plate 3 from being broken due to the force of the pressing member 5 after the pressing member 5 is fixed, in another preferred embodiment, the observation device further includes a sealing member 4. The sealing member 4 includes but is not limited to a flexible sleeve made of a refractory material such as a graphite sleeve. The sealing member 4 is arranged between the fire-resistant glass plate 3 and the upper layer area 211, and the end surface of the fire-resistant glass plate 3 abuts against the sealing member 4.
[0020] In order to further optimize the installation of the clamping piece 5 and prevent the clamping piece 5 from being unable to be removed when the fire-resistant glass plate 3 needs to be removed or the position of the fire-resistant glass plate 3 needs to be adjusted, in another embodiment of the present application, a first handle 51 and a second handle 52 are respectively provided on the inner wall of the clamping piece 5. On the end surface of the observation window 2, the first handle 51 and the second handle 52 are respectively located at the two ends of the same diameter. The first handle 51 and the second handle 52 both extend along the axial direction of the observation window 2, and the first handle 51 and the second handle 52 are arranged in the same direction. After the surface of the fire-resistant glass plate 3 is affected by the interference of oil smoke and the observation is affected, the first handle 51 and the second handle 52 can be held and rotated to disassemble the clamping piece 5 and then adjust or clean the fire-resistant glass plate 3. Similarly, the same operation can be performed when replacing the fire-resistant glass plate 3.
[0021] In summary, the utility model provides an observation window on the outer periphery of the observation port, in which a fire-resistant glass plate is embedded, so that construction personnel can observe the interior of the smoke exhaust rack without opening the observation port of the smoke exhaust rack, thereby ensuring the accuracy of the thermocouple detection device.
