[0002] A boiler flue fly ash sampler is a specialized device used to collect fly ash samples from the flue of a coal-fired boiler. It typically consists of a high-temperature resistant sampling tube, a filter device, a sealing structure, and an adjustment mechanism. It is inserted into the flue and collects fly ash particles using negative pressure or mechanical extraction. Combined with a multi-stage filtration system, it separates particles of different sizes to ensure the representativeness of the sample.

This includes a fly ash sampling mechanism comprising a fly ash collection component and a fly ash treatment component on one side. This boiler flue fly ash sampler features a novel structural design. During use, the snap-fit ​​block and snap-fit ​​groove structure allows for the installation and disassembly of the sampling bottle according to usage, effectively improving the stability of the connection between the sampling bottle and the cyclone separator. The connecting screw head and connecting screw hole structure also allow for the disassembly, connection, maintenance, and replacement of the intake and exhaust pipes according to usage. The heat-insulating sleeve and isolation cavity structure provide thermal insulation between the intake and exhaust components and the connection points of the mounting plate and cyclone separator, effectively preventing burns to operators.

[0004] While the aforementioned patent can provide insulation, the length of the suction pipe is fixed during use, making it unsuitable for different sampling environments and reducing the flexibility of the sampler. Therefore, a boiler flue fly ash sampler is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a boiler flue fly ash sampler, which aims to improve the problem that the existing technology cannot adapt to different sampling environments, thus reducing the flexibility of the sampler's use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a boiler flue fly ash sampler, including a sampling bottle 1. A cyclone separator 2 is installed on the top of the sampling bottle 1. This design cleverly utilizes the principle of cyclone separation, which allows larger fly ash particles to be separated first, reducing the impact on the sample during subsequent sampling. A suction tube 3 is rotatably connected to one side of the cyclone separator 2. The function of the suction tube 3 is to bring the gas in the flue into the sampling bottle 1 for analysis, ensuring the comprehensiveness and representativeness of the sampling.

[0034] The suction tube 3 is slidably connected to the outside of the connecting tube 4, and the bottom of the connecting tube 4 is fixedly connected to the suction nozzle 5. The design of the suction nozzle 5 ensures the rapid entry of airflow to improve sampling efficiency. During the sampling process, the suction nozzle 5 can flexibly adapt to different working environments to ensure a stable sampling flow rate. Extension blocks 6 are fixedly connected to the outside of the suction tube 3. The presence of the extension blocks 6 provides support for the length adjustment of the suction tube 3, so that the required sampling position can be reached more accurately.

[0035] Spring 7 is fixedly connected to the outer periphery of the suction tube 3. A sliding block 8 is fixedly connected to the other end of the spring 7. The elasticity of the spring 7 allows the suction tube 3 to smoothly return to its initial state when its length is adjusted, ensuring the stability of the system. A locking ball 9 is fixedly connected to the other end of the sliding block 8. The locking ball 9 plays a locking and fixing role, which can effectively prevent the suction tube 3 from moving accidentally during the sampling process.

[0036] The inner wall of the connecting tube 4 is provided with slots 10 on all four sides. The outer side of the locking ball 9 engages with the inner wall of the slot 10. The design of the slot 10 allows the locking ball 9 to be freely locked in different positions, providing users with multiple options to adapt to different sampling needs. The top of the cyclone separator 2 is provided with an exhaust component. The design of the exhaust component helps to remove unsampled gas in time during the sampling process, ensuring the purity of the sample. The outer side of the sliding block 8 abuts against the inner wall of the extension block 6, and the outer side of the extension block 6 is slidably connected to the inner wall of the connecting tube 4. This structural design ensures that the connecting tube 4 can move freely and stably, which helps to simplify the operation of the sampling equipment. The outer side of the suction tube 3 is fixedly connected with a handle 21. The presence of the handle 21 allows the operator to easily adjust the length and angle of the suction tube 3, greatly improving operability and flexibility.

[0037] refer to Figure 1 , Figure 4 and Figure 5 The exhaust assembly includes an exhaust pipe 19, the bottom of which is installed on top of the cyclone separator 2. The other end of the exhaust pipe 19 is fixedly connected to an exhaust head 20. This design can effectively guide the gas out and avoid affecting the stability of the sampling. A filter plate 12 is fixedly connected to the outside of the suction pipe 3. The filter plate 12 can effectively intercept larger particles, protect the operation of subsequent equipment, and ensure the accuracy of the data. Multiple flow grooves 13 are opened on the outside of the suction pipe 3. The presence of the flow grooves 13 can accelerate the gas flow speed, improve the sampling efficiency, and reduce the airflow resistance, which is crucial for improving the sampling quality. A filter box 11 is rotatably connected to the outside of the suction pipe 3. The structural design of the filter box 11 makes it easier to maintain and replace the filter material, enhancing the ease of use of the sampler.

[0038] A fixing block 14 is fixedly connected to the inner wall of the filter box 11. A spring 15 is fixedly connected to one side of the inner wall of the fixing block 14. The design of the spring 15 ensures that the cleaning plate 17 can always maintain appropriate pressure during operation, which helps to improve the cleaning effect and extend its service life. A sliding plate 16 is fixedly connected to the other end of the spring 15. The movement of the sliding plate 16 can drive the cleaning plate 17 to ensure the effectiveness of cleaning and avoid sampling failure due to filter blockage.

[0039] One side of the cleaning plate 17 contacts one side of the filter plate 12. The design of the cleaning plate 17 enables automatic cleaning of the surface of the filter plate 12 during operation, ensuring the unobstructed flow of the filter during sampling. The external sliding plate 16 is slidably connected to the inner wall of the fixed block 14. Its ingenious structure ensures the smoothness of the cleaning process and improves the overall reliability of the sampler. The filter box 11 is externally fixedly connected to the mounting plate 18. The design of the mounting plate 18 not only provides better support, but also serves as the basis for connecting the exhaust pipe 19 to other components, enhancing the structural stability of the entire device. The external fixed connection of the exhaust pipe 19 to the inner wall of the mounting plate 18 ensures the stability and sealing of the exhaust assembly.

[0040] Working principle: When the length of the suction tube 3 needs to be adjusted, the connecting tube 4 is pulled forcefully. The movement of the connecting tube 4 causes the extension block 6 to slide on the inner wall of the connecting tube 4. When the connecting tube 4 moves, the locking ball 9 presses against the inner wall of the connecting tube 4, causing the locking ball 9 to push the sliding block 8 to move. The movement of the sliding block 8 can compress the spring 7, causing the locking ball 9 to retract into the extension block 6. This allows the connecting tube 4 to move smoothly. When the connecting tube 4 moves to the appropriate position, the elastic potential energy released by the spring 7 causes the sliding block 8 to push the locking ball 9 to reset, so that the locking ball 9 engages with different slots 10, thereby fixing the connecting tube 4 and realizing the adjustment of the length of the suction tube 3, which can better sample according to the needs.

[0041] When sampling, the gas flows into the filter box 11 through the flow channel 13 and is then filtered by the filter plate 12. When the sampling angle needs to be adjusted, the handle 21 can be turned to make the suction tube 3 drive the connecting tube 4 and the suction nozzle 5 to rotate, thereby adjusting the angle and facilitating sampling at different positions. During rotation, the cleaning plate 17 will contact the surface of the filter plate 12, thereby cleaning the surface of the filter plate 12 and preventing impurities from clogging the filter plate 12. The elastic potential energy of the spring 15 can make the sliding plate 16 push the cleaning plate 17 to ensure that the cleaning plate 17 is tightly attached to the surface of the filter plate 12, which not only improves the cleaning effect but also extends the service life of the cleaning plate 17.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
