Description

Technical Field

[0001] This utility model relates to the field of temperature monitoring technology, and more specifically, to a temperature monitoring device for the exhaust rack of a carbon roasting furnace. Background Technology

[0002] A carbon roasting furnace typically consists of multiple chambers (usually 20-30), each corresponding to a different roasting stage (preheating, heating, holding, and cooling). The exhaust hood (also known as a "smoke collector" or "exhaust hood") is a movable or fixed metal frame device connected via a sealed interface to the flue gas outlet on the top or side of the chamber in the "exhaust stage." Its core function is to collect the high-temperature flue gas generated during roasting and guide it into subsequent purification systems (such as electrostatic precipitators and bag filters) to ultimately achieve compliant emissions.

[0003] In actual operation, the internal guide plates of the exhaust frame are prone to deformation and blockage due to the scouring of high-temperature flue gas, leading to localized accumulation of flue gas and preventing heat from being properly conducted to the flue gas channel, thus causing an abnormal rise in the frame temperature. Prolonged exposure to high temperatures will cause the steel of the exhaust frame to undergo high-temperature creep. If the temperature continues to exceed the standard, it will accelerate the decline in steel strength, potentially leading to serious equipment accidents such as frame cracking and collapse. Therefore, a temperature monitoring device for the exhaust frame of a carbon roasting furnace is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a carbon roasting furnace exhaust rack temperature monitoring device, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a temperature monitoring device for the exhaust rack of a carbon roasting furnace, including a base, on which a monitoring component is provided;

[0006] The monitoring component includes a protective cover mounted on the top of the base, with a misalignment opening through the protective cover. The base has a mounting groove, and a rotating shaft is rotatably connected within the mounting groove. One end of the rotating shaft is fitted with a gear.

[0007] A horizontal plate is slidably connected inside the misaligned opening. The bottom of the horizontal plate has a toothed groove that meshes with a gear. A temperature sensor for temperature monitoring is provided at one end of the horizontal plate.

[0008] Optionally, in one possible implementation, the horizontal plate has a through hole communicating with the toothed groove, the temperature sensor is embedded in the through hole so that the high-temperature flue gas comes into contact with the temperature sensor through the through hole, a processor is embedded in the top of the inner cavity of the protective cover, the processor extends to the surface of the protective cover, a motor for driving the rotating shaft is provided at one end of the protective cover, the motor is detachably connected to the protective cover body by bolts, the base is hollow, and heat exchange guide pipes are embedded at both ends of the base, the toothed groove is horizontally placed in the misaligned opening, and the toothed groove is slidably connected to the misaligned opening;

[0009] The technical effects and advantages of this utility model are as follows:

[0010] The temperature sensor is driven to move back and forth along the exhaust frame by a motor-driven gear and toothed transmission. Combined with the through-hole design that allows the sensor to directly contact the high-temperature flue gas, the temperature of the entire exhaust frame can be monitored. This avoids local high-temperature missed detections caused by the deformation of the guide plate and the accumulation of flue gas, and effectively prevents the risk of high-temperature creep of steel.

[0011] The hollow base, combined with the heat exchange guide tube, can cool the device through the circulation of cooling medium; the protective cover isolates high-temperature flue gas and dust, protects the internal transmission and electronic components, avoids monitoring interruption due to high temperature damage, and ensures monitoring stability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The carbon roasting furnace exhaust rack temperature monitoring device disclosed in this embodiment includes a base 1. The base 1 adopts a hollow steel structure design, which reduces the overall weight of the device, facilitates installation and movement, and provides installation space for the heat exchange guide pipe 11. Heat exchange guide pipes 11 are embedded at both ends of the base 1. The heat exchange guide pipes 11 are made of high-temperature resistant stainless steel and can be circulated with cooling media such as cooling water or cooling air. During device operation, the circulating flow of the cooling media can cool the base 1 and surrounding components, preventing damage to internal components due to high-temperature conduction from the exhaust rack and extending the equipment's service life.

[0020] The top of the base 1 has a mounting slot 12, as shown in the attached figure. Figure 3 As shown, the dimensions of the mounting groove 12 are adapted to the rotating shaft 4. The rotating shaft 4 is rotatably connected to the mounting groove 12 via bearings, ensuring that the rotating shaft 4 can rotate stably and smoothly. A gear 5 is fitted onto one end of the rotating shaft 4, and the gear 5 is fixed to the rotating shaft 4 by a key connection, ensuring that the rotating shaft 4 can synchronously drive the gear 5 to rotate.

[0021] A protective cover 2 is fixedly installed on the top of the base 1. The protective cover 2 is made of high temperature resistant alloy material and has an overall rectangular box structure. Its function is to protect the transmission components such as gears 5 and rotating shafts 4 and electronic components such as processor 9 inside the device, so as to prevent high temperature flue gas from directly washing over and dust accumulation from damaging the components, and at the same time reduce the interference of the external environment on the monitoring accuracy.

[0022] As attached Figure 4 As shown, a motor 10 is detachably connected to one end of the protective cover 2 via bolts. The motor 10 is a servo motor, and its output shaft is connected to the end of the rotating shaft 4 away from the gear 5 via a coupling. The detachable connection facilitates the later maintenance and replacement of the motor 10. The use of a servo motor enables precise control of the rotation speed and rotation angle of the rotating shaft 4, thereby adjusting the moving speed and position of the temperature sensor 8 to meet the needs of different monitoring scenarios.

[0023] The processor 9 is embedded in the top of the inner cavity of the protective cover 2, as shown in the attached diagram. Figure 4As shown, the processor 9 uses an industrial-grade microcontroller, whose surface extends to the outside of the protective cover 2. The extended part is equipped with a data interface and a display panel. The processor 9 is electrically connected to the temperature sensor 8 and the motor 10 via wires. It can receive temperature data collected by the temperature sensor 8 in real time and analyze and process the data. When the temperature exceeds a preset threshold, the processor 9 can issue an audible and visual alarm signal through the display panel and transmit the alarm information to the remote monitoring system through the data interface. In addition, the processor 9 can also send control commands to the motor 10 to adjust the monitoring position of the temperature sensor 8 according to monitoring needs.

[0024] The protective cover 2 has a through-hole 3, which is elongated and its length is consistent with the length of the exhaust rack, providing a channel for the sliding of the horizontal plate 6. The horizontal plate 6 is slidably connected inside the through-hole 3. The horizontal plate 6 is made of high-strength, high-temperature resistant plastic material, which not only has good structural strength to support the stable movement of the temperature sensor 8, but also avoids deformation under high temperature that would affect the sliding accuracy.

[0025] The bottom of the horizontal plate 6 is provided with a toothed groove 7. The tooth pitch and module of the toothed groove 7 are adapted to the gear 5, and the toothed groove 7 is horizontally placed in the misalignment opening 3 to mesh with the gear 5, as shown in the attached figure. Figure 3 As shown. When the motor 10 drives the rotating shaft 4 to rotate, the gear 5 rotates synchronously. Through the meshing transmission between the gear 5 and the tooth groove 7, the horizontal plate 6 is driven to slide back and forth along the length direction of the misalignment opening 3, thereby realizing the movement and monitoring of the temperature sensor 8 in the length direction of the smoke exhaust rack, and expanding the monitoring coverage.

[0026] A through hole is provided on the horizontal plate 6, which communicates with the toothed groove 7. The temperature sensor 8 is embedded in the through hole, as shown in the attached figure. Figure 3 As shown in the diagram, this design allows the high-temperature flue gas inside the exhaust frame to directly contact the temperature sensor 8 through the through-hole, reducing temperature conduction loss and improving the response speed and accuracy of temperature monitoring. The temperature sensor 8 is a K-type thermocouple sensor, covering both the normal operating temperature of the exhaust frame and abnormally high temperature scenarios, meeting monitoring requirements.

[0027] The specific working principle is as follows: the device is fixed at the designated monitoring position of the exhaust rack via the base 1, ensuring that the temperature sensor 8 is aligned with the flue gas circulation area of ​​the exhaust rack; cooling medium is introduced into the heat exchange guide pipe 11 to start the cooling circulation system; the temperature monitoring threshold and the operating parameters of the motor 10 are set through the display panel of the processor 9.

[0028] During the temperature monitoring process, the processor 9 sends a start command to the motor 10, which drives the shaft 4 to rotate, thereby driving the gear 5 to rotate. Through the meshing transmission between the gear 5 and the tooth groove 7, the horizontal plate 6 slides back and forth along the misalignment opening 3. During the movement of the horizontal plate 6, the temperature sensor 8 directly contacts the high-temperature flue gas through the through hole, collects the temperature data of different positions of the exhaust frame in real time, and transmits the data to the processor 9.

[0029] The processor 9 analyzes the received temperature data in real time. If the temperature is detected to be lower than the preset threshold, the display panel will show the current temperature value and the monitoring location in real time. If the temperature exceeds the preset threshold, the processor 9 will immediately trigger an audible and visual alarm and transmit the alarm information to the remote monitoring system through the data interface to remind staff to troubleshoot the fault in time.

[0030] Throughout the monitoring process, the cooling medium in the heat exchange guide pipe 11 continuously circulates to cool down the base 1 and surrounding components; the protective cover 2 effectively isolates high-temperature flue gas and dust, protects internal transmission components and electronic components, and ensures stable operation of the device.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
