Description

Technical Field

[0001] This utility model relates to the field of temperature measuring instrument technology, specifically a boiler furnace temperature measuring instrument. Background Technology

[0002] A thermometer is a device used to monitor the temperature inside a boiler furnace. It typically employs radiation thermometry, a non-contact method, to calculate the temperature by acquiring images of the flame's radiation or a specific spectrum within the furnace. This device is crucial for the safe operation and efficiency optimization of boilers.

[0003] Existing boilers require the use of a temperature measuring instrument to test the temperature inside the furnace to prevent the furnace temperature from becoming too high. Generally, a photoelectric detector converts the infrared radiation from the surface of an object into an electrical signal. The signal processing module processes the signal collected by the detector and transmits the data to the display module, which then displays the measurement results.

[0004] However, since the thermometer needs to be inserted into the furnace to measure the temperature, and the temperature inside the furnace is high, the thermometer will experience accelerated aging and wear of its internal components when exposed to high temperatures for a long time, resulting in reduced sensor sensitivity and inability to measure the furnace temperature in real time. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a boiler furnace temperature measuring instrument to solve the problem mentioned in the background technology that the temperature measuring instrument needs to be inserted into the furnace to measure the temperature. However, the temperature inside the furnace is high, and the temperature measuring instrument will be exposed to a high-temperature environment for a long time, which will accelerate the aging and wear of the internal components, resulting in a decrease in the sensitivity of the sensor and the inability to measure the temperature of the furnace in real time.

[0021] Beneficial effects

[0022] Compared with the prior art, this utility model provides a boiler furnace temperature measuring instrument, which has the following beneficial effects:

[0023] This boiler furnace temperature measuring instrument is equipped with a fan that blows outside air into the instrument's casing, causing the hot air inside to circulate and exit through the exhaust port, thus cooling the inside of the instrument. Simultaneously, cooling water from the water tank is transported to the cooling pipes via a water supply pipe and then returned to the water tank via a return pipe. This ensures that the air blown in by the fan is significantly cooler than the surrounding temperature of the boiler, further enhancing the cooling effect on the temperature measuring instrument. Furthermore, a semiconductor cooling module continuously cools the water in the tank, further improving the cooling efficiency and preventing the temperature measuring instrument from operating at high temperatures for extended periods. This protects the internal components of the temperature measuring instrument, preventing a decrease in sensitivity and enabling real-time temperature measurement of the furnace.

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.

[0032] This utility model provides a technical solution: a boiler furnace temperature measuring instrument. Please refer to [link / reference needed]. Figure 1 This includes a thermometer housing 1, and a photodetector 2 is installed on the left side of the inner cavity of the thermometer housing 1. Please refer to [link / reference]. Figure 2 A signal processing module 3 is installed on the right side of the photoelectric detector 2, a data display 4 is installed on the upper surface of the thermometer housing 1, and an alarm 5 is installed on the right side of the data display 4.

[0033] The infrared radiation from the object's surface is converted into an electrical signal by the photoelectric detector 2. The signal processing module 3 processes the signal collected by the detector, and the measurement result is displayed on the data display 4. When the measurement result is higher than the normal temperature, the alarm 5 sounds to remind the staff.

[0034] Mounting cover 6 is located on the right side of the thermometer housing 1. A fan 7 is installed inside the mounting cover 6. A water tank 8 is installed at the bottom of the thermometer housing 1. A semiconductor cooling module 9 is installed at the bottom of the water tank 8.

[0035] Please see Figure 3 A water supply pipe 10 is located on the right side of the water tank 8. A cooling pipe 11 is connected to the top of the water supply pipe 10. The cooling pipe 11 is located inside the mounting cover 6. A return pipe 12 is installed through the back of the mounting cover 6 and communicates with the inner cavity of the water tank 8. Please refer to [link / reference needed]. Figure 1 An exhaust port 13 is provided on the left side of the upper surface of the thermometer housing 1, and an air check valve is installed inside the exhaust port 13.

[0036] Starting the fan 7 blows outside air into the interior of the thermometer housing 1, causing the hot air inside the housing 1 to circulate and be discharged through the exhaust port 13, thus cooling the interior of the thermometer housing 1. At the same time, the cooling water in the water tank 8 is transported to the cooling pipe 11 through the water supply pipe 10 and returned to the water tank 8 through the return pipe 12. This ensures that the air blown in by the fan 7 is much lower than the temperature around the boiler, which can more effectively cool the thermometer. Furthermore, the semiconductor cooling module 9 continuously cools the water in the water tank 8, further improving the cooling effect of the thermometer, preventing the thermometer from being in a high-temperature environment for a long time, protecting the internal components of the thermometer, preventing the internal components from becoming less sensitive, and enabling real-time temperature measurement of the furnace.

[0037] Please see Figure 5 A water pump 14 is installed on the right side of the water tank 8. The water pump 14 is connected to the left end of the water supply pipe 10. Starting the water pump 14 can transport the water in the water supply pipe 10 to the cooling pipe 11.

[0038] A suction pipe 15 is installed on the left side of the water pump 14. The suction pipe 15 extends into the interior of the water tank 8, and water in the water tank 8 can be drawn into the water pump 14 through the suction pipe 15.

[0039] Preferably, threaded grooves 16 are provided on the upper surface of the water supply pipe 10 and the lower surface of the cooling pipe 11. A connecting cylinder 17 is screwed onto the connection between the water supply pipe 10 and the cooling pipe 11. By rotating the connecting cylinder 17 downward, the water supply pipe 10 and the cooling pipe 11 can be separated, so that the water pump 14 can be easily replaced when it is damaged.

[0040] Please see Figure 4 The surface of both the outer shell 1 and the mounting cover 6 of the thermometer is equipped with mounting edges 18, and mounting rods 19 are evenly distributed between the mounting edges 18. The mounting cover 6 can be disassembled by removing the mounting rods 19.

[0041] A filter frame 20 is installed on the right side of the mounting cover 6. A filter screen 21 is installed on the surface of the filter frame 20. The filter screen 21 can prevent dust from entering the interior of the thermometer housing 1.

[0042] Positioning rods 22 are evenly distributed on the surface of the filter frame 20. The positioning rods 22 all pass through the surface of the filter frame 20 and are screwed onto the mounting cover 6. The positioning rods 22 can be removed to disassemble the filter frame 20 and facilitate cleaning of the filter screen 21.

[0043] Please see Figure 2 The signal processing module 3 has brackets 23 installed on both sides of its bottom. Bolts 24 are screwed onto the upper surface of each bracket 23. The brackets 23 are used to install the signal processing module 3.

[0044] Please see Figure 1 A sealing plate 25 is installed on the front of the thermometer housing 1. Please refer to [link / reference]. Figure 6 Connecting rods 26 are screwed to the four corners of the front of the sealing plate 25. Opening the sealing plate 25 allows for easy disassembly of the signal processing module 3.

[0045] Please see Figure 1 The surface of the thermometer housing 1 is equipped with a mounting block 27. The mounting block 27 is a ring design, and threaded rods 28 are evenly distributed on the surface of the mounting block 27. The thermometer can be installed on the surface of the boiler through the threaded rods 28.

[0046] The working process of this device is as follows: First, the infrared radiation from the surface of the object is converted into an electrical signal by the photoelectric detector 2. The signal collected by the detector is processed by the signal processing module 3. The measurement result is displayed by the data display 4. When the measurement result is higher than the normal temperature, the alarm 5 sounds to remind the staff. Then, the fan 7 is started to blow outside air into the interior of the thermometer housing 1, causing the hot air in the thermometer housing 1 to flow and be discharged through the exhaust port 13, which can cool the interior of the thermometer housing 1. Finally, the cooling water in the water tank 8 is transported to the cooling pipe 11 through the water supply pipe 10 and returned to the water tank 8 through the return pipe 12. This makes the air blown in by the fan 7 much lower than the temperature around the boiler, which can more effectively cool the thermometer. In addition, the semiconductor cooling module 9 can continuously cool the water in the water tank 8, which further improves the cooling effect of the thermometer, avoids the thermometer being in a high-temperature environment for a long time, protects the internal components of the thermometer, prevents the internal components from becoming less sensitive, and can measure the temperature of the furnace in real time.
