Abstract
Description
Technical Field
[0001] This utility model relates to the field of fly ash carbon content detection technology, and in particular to a rapid detection device for fly ash carbon content in thermal power plants. Background Technology
[0002] With the rapid development of the power industry and waste incineration, fly ash refers to the fine ash particles that enter the tail flue with the flue gas after combustion in the boiler furnace. The ratio of the combustible content in fly ash to the total amount of fly ash is called the carbon content of fly ash. Therefore, the carbon content of fly ash is an important indicator for measuring the combustion status.
[0003] Currently, when testing the carbon content of fly ash, workers need to insert the detection probe of the online fly ash carbon content measuring instrument into the flue to detect the carbon content. The detection information is then transmitted to the processor in the measuring instrument for analysis via a signal connection line. However, to ensure the accuracy of the fly ash carbon content detection results, multiple timed detection methods are mostly used to obtain average data on the fly ash carbon content. This sampling operation requires workers to frequently perform handheld detection, which is quite cumbersome. Furthermore, during the interval between the first and second detections, old and new fly ash will adhere to the surface of the detection probe, leading to inaccurate detection results.

[0016] By adopting the above technical solution, the use of the limiting rod can play an important limiting role in the transmission component, so as to ensure that the clamping component can be deployed normally.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] Reference Figure 1-4 A rapid detection device for carbon content in fly ash from thermal power plants includes a transmission rod 1, a base 3 fixedly connected to the bottom of the transmission rod 1, three connecting rods b16 rotatably connected to the outer circumference of the base 3, an external thread 2 on the top of the outer side of the transmission rod 1, a transmission component 4 connected to the outer thread of the external thread 2, three connecting rods a6 rotatably connected to the outer circumference of the transmission component 4, three clamping components 7 on the outer circumference of the transmission rod 1, and fixing components 10 fixedly connected to the clamping components 7 near the inner wall of the transmission rod 1. The ends of the connecting rods a6 away from the transmission component 4 are rotatably connected to the fixing components 10, and the ends of the connecting rods b16 away from the base 3 are rotatably connected to the fixing components 10. This device is used to detect the carbon content in fly ash. During testing, the operator can rotate the transmission rod 1. The rotation of the transmission rod 1 drives the transmission component 4 to move. Under the limiting action of the limiting component, the transmission component 4 can move straight towards the base 3, thereby pushing the connecting rod a6 to rotate. Then, with the support of the connecting rod b16, the three clamping parts 7 can unfold, so that the outer wall of the clamping parts 7 can fit and abut against the flue. The testing device can then be placed in the flue for use. It is applicable to flues of different sizes. During the testing process, the operator does not need to hold it all the time, reducing the workload of the operator and making it more convenient to use.
[0031] Specifically, a base 8 is fixedly connected to the bottom of the base 3, and a detection probe 9 is fixedly installed on the bottom of the base 8. The detection probe 9 can detect the carbon content of fly ash in the flue and transmit the information to an external measuring instrument via a signal connection line. A groove 12 is provided at the bottom of the base 8, surrounding the detection probe 9. A cleaning component is provided at the bottom of the base 8. The cleaning component includes a gear ring 15 rotatably installed inside the groove 12. The rotation of the transmission gear a14 drives the gear ring 15 to rotate, thereby enabling... The cleaning brush head 13 cleans the old fly ash on the outer surface of the detection probe 9, thereby improving the detection accuracy of fly ash. The inside of the tank 12 is rotatably connected to the transmission gear a14, which meshes with the gear ring 15. The bottom end of the gear ring 15 is fixedly connected to the cleaning brush head 13. The three connecting rods b16 are axially equidistant from the center of the base 3. The use of connecting rods b16 makes connecting rod a6 more stable during adjustment, thereby improving support stability. The three connecting rods a6 are axially equidistant from the center of the transmission component 4.
[0032] Specifically, the cleaning brush head 13 has an L-shaped structure. A soft brush is provided on the side of the cleaning brush head 13 closest to the detection probe 9. The soft brush fits against the outer surface of the detection probe 9, improving the cleaning effect of the soft brush on the fly ash outside the detection probe 9. A limiting component is provided at the top of the base 3. The limiting component includes three limiting rods 5 fixedly connected to the top of the base 3. The limiting rods 5 play an important limiting role in the transmission component 4, ensuring that the clamping component 7 can unfold normally. The limiting rods 5 are all slidably connected to the inside of the transmission component 4. An embedded drive motor is located inside 8 and above the transmission gear a14. The rotation of the output shaft of the drive motor can drive the transmission gear a14 to rotate, thereby providing a power source for the transmission gear a14. The output shaft of the drive motor is fixedly connected to the rotation shaft of the transmission gear a14. A handle is fixedly connected to the top of the transmission rod 1. The outer wall of the abutment 7 is provided with anti-slip texture 11. The anti-slip texture 11 can increase the friction coefficient between the abutment 7 and the inner wall of the flue, thereby improving the stability of the entire device during use.
[0033] Working principle: First, when testing the carbon content of fly ash, the operator can rotate the handle, which in turn drives the transmission rod 1 to rotate. This causes the transmission component 4 to move, and under the limiting action of the limiting rod 5, the transmission component 4 moves straight towards the base 3. This, in turn, pushes the connecting rod a6 to rotate. Then, supported by the connecting rod b16, the three clamping parts 7 unfold, allowing the outer wall of the clamping parts 7 to fit and press against the flue pipe. The anti-slip texture 11 further enhances the contact between the clamping parts 7 and the inner wall of the flue pipe. The coefficient of friction allows the detection device to be installed in the flue. By using the detection probe 9, the carbon content of fly ash in the flue can be detected, and the information is transmitted to an external measuring instrument via a signal connection line. After the first fly ash detection is completed, the drive motor can be started immediately through the control panel on the measuring instrument to drive the transmission gear a14 to rotate, which in turn drives the gear ring 15 to rotate. The old fly ash on the outer surface of the detection probe 9 can then be cleaned with the cleaning brush head 13, thereby improving the detection accuracy of fly ash.
