Description

Technical Field

[0001] The utility model relates to the technical field of carbon content measuring devices, in particular to a fly ash carbon content measuring device. Background Art

[0002] The carbon content of boiler fly ash is an important indicator reflecting the combustion efficiency of coal-fired boilers in thermal power plants. Real-time measurement of the carbon content in fly ash will be beneficial for monitoring boiler combustion, guiding combustion adjustments to reduce coal consumption, and improving the economy and safety of unit operation.

[0003] After searching, the patent publication number CN211718028U discloses a device for measuring the carbon content of fly ash in a waste incineration power plant, including a pulverized coal pipeline, one side of which is connected to an air blowing pipe, a sampling head is provided below the air blowing pipe, a regulating valve is embedded in the surface of the sampling head and the air blowing pipe, one end of the air blowing pipe is connected to a compressor, one end of the sampling head is connected to a separator, and the bottom end of the separator is connected to a mounting cover. The utility model is provided with a mounting cover, and the slider enters the interior of the annular cavity to achieve blocking and limiting of the mounting cover. The mounting cover and the separator are quickly installed. The fly ash separated by the separator is blocked by the mounting cover to prevent the fly ash from scattering. A card block and a card seat are provided, and the card block is placed in the card seat. When the positioning block reaches the positioning hole area, the spring restores its elastic deformation, and the positioning block enters the positioning hole, thereby achieving rapid installation of the separator.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative document, the pulverized coal in the pulverized coal pipeline is taken out by a sampling head, and the fly ash is collected in a sampling bottle by a separator, and the carbon content of the fly ash in the sampling bottle is tested. However, in the existing situation, the sampling head is still placed inside the pulverized coal pipeline when no sampling is performed. If it is kept for too long, one end of the sampling head located in the pulverized coal pipeline will be blocked. If it is necessary to sample and test the carbon content of the fly ash in the pulverized coal pipeline in the future, the sampling head needs to be unblocked, thereby reducing the efficiency of the fly ash carbon content detection. Therefore, there is an urgent need in this field to improve the fly ash carbon content measuring device to solve the defects of the existing technology. Utility Model Content

A first adjusting bolt 17 with one end extending to the outside is rotatably connected in the sliding groove 16, and the first adjusting bolt 17 passes through the two sliding blocks 15 and is threadedly connected thereto. When the first adjusting bolt 17 rotates, the two sliding blocks 15 move toward or away from each other, and a second limiting nut 18 for limiting its position is threadedly connected to the side of the first adjusting bolt 17 located on the outside. The ends of the two clamping rings 14 away from the sliding block 15 are fixedly connected to a connecting plate 19, and a fastening bolt 20 for fixing is provided between the two connecting plates 19.

[0037] Specific implementation of this embodiment: The mounting plate 13 is installed on the wall 3 by fasteners. When the separator 4 needs to be installed, the separator 4 is placed between the two clamping rings 14. By rotating the first adjusting bolt 17, the threaded teeth on the side of the first adjusting bolt 17 are opposite and symmetrical. When the first adjusting bolt 17 is rotated, the two sliding blocks 15 are driven to move toward each other in the sliding groove 16. The two sliding blocks 15 drive the two clamping rings 14 to move toward each other. The two clamping rings 14 clamp the separator 4. Tighten the second limiting nut 18 to limit and fix the position of the first adjusting bolt 17 and fix the separator 4. At the same time, the two connecting plates 19 are fixed by fastening bolts 20 to improve the stability of the separator 4 after fixation.

[0040] Specific implementation method in this embodiment: When the carbon content of fly ash in the pipeline 1 needs to be detected, it is first necessary to install the sampling bottle 5 between the separator 4, and place the sampling bottle 5 on the tray 23 adapted thereto. By rotating the second adjusting bolt 22, the second adjusting bolt 22 drives the tray 23 to move up, and when the tray 23 moves, one end of the limiting plate 25 slides in the limiting groove 26 to limit the position of the tray 23. The tray 23 drives the sampling bottle 5 to move up, and the upper end of the sampling bottle 5 is clamped in the positioning groove 28, and the sealing ring 29 is squeezed to achieve sealing between the separator 4 and the sampling bottle 5, and the sampling bottle 5 and After the separator 4 is connected, tighten the third limit nut 24 to limit and fix the position of the second adjusting bolt 22. Compared with the clamping connection in the prior art, the existing clamping connection method will have gaps after long-term use, causing the sealing effect to deteriorate. This method has a better sealing effect and increases the service life. The sealing strip 11 is made of high-temperature resistant and elastic material to ensure that the sealing strip 11 will not melt due to high temperature. The length of the sampling tube 2 in the pipeline 1 is equal to the spacing between the opposite side walls of the pipeline 1, which increases the range of fly ash collection. The clamping ring 14 is elastic and deformable, and can fix separators 4 of different sizes.
