Description

Technical Field

[0001] This utility model relates to the technical field of monitoring facilities for sintering ring coolers, specifically to an internal temperature monitoring device for sintering ring coolers. Background Technology

[0002] The function of the sintering ring cooler is to effectively cool the hot sintered ore discharged from the sintering machine. Compared with the belt cooler, the ring cooler has the advantages of smaller footprint, lower investment, and higher equipment utilization.

[0003] The sintering ring cooler is a fully enclosed operating environment. Due to the enclosed space and lack of direct sinter temperature monitoring devices, operators have difficulty intuitively grasping the actual temperature and particle size of the sinter inside the ring cooler. This can easily lead to excessively high sinter discharge temperatures. Excessively high discharge temperatures pose a fire risk, and if timely and effective monitoring and intervention are not implemented, they may quickly escalate into serious accidents, causing incalculable losses to production facilities, personnel safety, and the environment.

[0014] Compared with the prior art, this utility model provides a temperature monitoring device for the internal temperature of a sintering ring cooler, which has the following beneficial effects:

[0015] This invention enables precise observation of the sinter ore surface height and real-time temperature measurement. It not only allows for remote monitoring of the dynamic changes in the sinter ore surface, ensuring a suitable sinter layer thickness and preventing excessively high or low stacking levels from affecting sintering efficiency and subsequent conveying efficiency, but also captures and provides real-time, accurate temperature and particle size data of the sinter ore surface. This allows operators to detect temperature and particle size anomalies immediately, facilitating effective temperature control and preventing overheating or red-hot states. This prevents high-temperature sinter or red-hot ore from entering the belt conveyor system, ensuring the safe and stable operation of the entire production line. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1 and Figure 2 A temperature monitoring device for the internal environment of a sintering ring cooler includes a thermal imager 10, a distance sensor 20, a thermocouple 30, an ejection device 60, and a cooling device. The thermal imager 10, distance sensor 20, and thermocouple 30 are all mounted on the outside of the ring cooler base 40. The detection ends of the thermal imager 10 and distance sensor 20 extend into the ring cooler base 40 to monitor the surface temperature and height of the hot ore within the base 40. The detection end of the thermocouple 30 extends into the ring cooler base 40 to monitor the ambient temperature inside the base 40. The detection end of the thermal imager 10 is a pinhole lens 11, which can be moved into or out of the ring cooler base 40 by the ejection device 60. The cooling device can provide air cooling to the pinhole lens 11 when the temperature is too high.

[0021] In this embodiment, considering that the sintering material inside the annular cooler is affected by high-temperature heat flow, which can cause slag splashing, if a conventional lens is used, the large impact surface would easily cause the slag to hit the lens, resulting in severe wear or even breakage of the lens, rendering the equipment unable to work properly and increasing equipment maintenance costs and workload. Meanwhile, to avoid the lens being adversely affected by prolonged exposure to high temperatures, the thermal imager 10 uses a pinhole lens specifically designed for blast furnaces. Furthermore, to comprehensively monitor the temperature of the hot ore 50 inside the annular cooler base 40, multiple thermal imagers 10 can be used in conjunction at intervals.

[0022] In this embodiment, the ranging sensor 20 can be a sensor or scanner that measures height changes by laser, which is already available in the prior art.

[0023] In this embodiment, an opening 42 is formed on the annular cooler base cover 40 to cooperate with the pinhole lens 11, so that the pinhole lens 11 can be moved into or out of the annular cooler base cover 40.

[0024] In this embodiment, the ejection device 60 can be an existing electric push rod, the output end of which can be fixedly connected to a lifting frame 61. The lower end of the lifting frame 61 is sleeved on the outside of the pinhole lens 11 and fixed to it with bolts or other fasteners, or the two can be assembled together by clamping. Then, the pinhole lens 11 can be moved by the translation of the output end of the electric push rod, and the lifting frame 61 can be used to drive it to extend into or out of the annular cooler base cover 40.

[0025] In this embodiment, the cooling device includes a cooling air pipe 70, a shut-off valve 80, and a filter 90. An external air pump is connected to the input end of the filter 90, and the output end of the filter 90 is connected to one end of the cooling air pipe 70. Air pumped in by the air pump can be filtered by the filter 90 before entering the cooling air pipe 70. The other end of the cooling air pipe 70 is connected to an opening 42, allowing the cooling air pipe 70 to output a clean airflow for cooling the pinhole lens 11. The shut-off valve 80 is installed on the cooling air pipe 70 and is used to control the on / off state of the cooling air pipe 70, thereby assisting in controlling the cooling of the pinhole lens 11.

[0026] The system of the present invention may further include a control system and a display. The control system is used to control the driving operation of the aforementioned exit device and can be signal-connected to the thermal imager, ranging sensor, and thermocouple. The control system, through an electrical connection with the display, outputs and displays the dynamic changes in the hot ore surface and the real-time measured temperature, as well as the ambient temperature inside the annular cooler base. It should be understood that this control system is not particularly limited and can be implemented using existing control technologies, which will not be elaborated upon here.
