[0014] Compared with the prior art, the beneficial effects of this utility model are: this low-concentration smoke and dust sampling device not only realizes multi-channel collection, but also realizes the screening of large particles and the cleaning of the inner wall of the tube; By setting up a first thread, a distribution chamber, a connecting seat, a second thread, and a collection head, in use, the connecting seat is connected to the left side of the pipe body, the distribution chamber is fixedly connected to the left side of the connecting seat, and seven sets of collection heads are opened on the left side of the distribution chamber, so as to realize the synchronous collection of smoke and dust at different locations in the flue, avoid the single-point sampling deviation caused by uneven airflow distribution, and thus more accurately reflect the overall emission concentration, improve the accuracy, reliability and efficiency of sampling data; By setting up a limiting ring, screen, slag outlet and slag collection bucket, the sample enters the tube through the sampling head during use. By setting a screen inside the tube, large particles such as combustion residue, metal fragments and fibers that may be mixed in with the flue gas are prevented from entering the subsequent sampling system and causing subsequent pipeline blockage or filter membrane damage by impacting the screen and falling from the slag outlet into the slag collection bucket below. The system is equipped with a cleaning ring, a first movable groove, a second movable groove, a movable block, a connecting rod, and a second handle. During use, manually moving the two sets of second handles causes the connecting rod to move to the right in the second movable groove. The right side of the connecting rod is fixedly connected to the movable block, which moves to the right in the first movable groove. This, in turn, causes the cleaning ring to move to the right. The outer diameter of the cleaning ring matches the inner diameter of the pipe body, thus cleaning the inside of the pipe, eliminating adsorbed residue on the inner wall, ensuring data accuracy, extending continuous operating time, and reducing maintenance frequency.

A connecting seat 10 is fixedly connected to the right side of the distribution chamber 9. A first thread 8 is opened at the left end of the outer side of the tube body 1. A second thread 11 is opened on the side of the connecting seat 10 near the tube body 1. The first thread 8 and the second thread 11 are matched in size. The seven sets of collection heads 12 are arranged symmetrically. The collection heads 12, the distribution chamber 9, and the tube body 1 are connected internally. The size of the filter basket 6 is matched with the mounting hole 5. The first handle 7 can pull out the filter basket 6. The tube body 1 and the collection box 3 are connected internally. Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, during use, a connecting seat 10 is threadedly connected to the left side of the pipe body 1, and a distribution chamber 9 is fixedly connected to the left side of the connecting seat 10. Seven sets of sampling heads 12 are opened on the left side of the distribution chamber 9, thereby realizing the synchronous collection of smoke and dust at different locations in the flue, avoiding single-point sampling deviation caused by uneven airflow distribution, and thus more realistically reflecting the overall emission concentration, improving the accuracy, reliability and efficiency of sampling data.

[0019] A limiting ring 13 is fixedly connected inside the pipe body 1, and a screen 14 is movably connected inside the pipe body 1. A slag outlet 15 is opened at the bottom end of the pipe body 1, and a slag collection bucket 16 is fixedly connected to the bottom end of the slag outlet 15. The outer diameter of the screen 14 matches the inner diameter of the pipe body 1. The pipe body 1, the slag outlet 15, and the slag collection bucket 16 are internally connected, and the limiting ring 13 and the screen 14 are tightly fitted together. Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, during use, the sample enters the tube body 1 through the sampling head 12.

A cleaning ring 17 is movably connected to the right side inside the pipe body 1. Two sets of movable blocks 20 are fixedly connected to the front and rear ends of the cleaning ring 17. Two sets of second movable grooves 19 are provided at the front and rear ends of the pipe body 1. Connecting rods 21 are movably connected inside the two sets of second movable grooves 19. Two sets of second handles 22 are fixedly connected to the left side of the two sets of connecting rods 21. The outer diameter of the cleaning ring 17 matches the inner diameter of the pipe body 1. The cleaning ring 17 can move left and right inside the pipe body 1. The two sets of first movable grooves 18 are arranged symmetrically front and back. The two sets of second movable grooves 19 are arranged symmetrically front and back. The size of the two sets of connecting rods 21 matches the second movable grooves 19. The right side of the two sets of connecting rods 21 is fixedly connected to the movable blocks 20. The size of the two sets of connecting rods 21 matches the second movable grooves 19. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, by manually moving the two sets of second handles 22, the second handles 22 drive the connecting rod 21 to move to the right in the second movable groove 19. The right side of the connecting rod 21 is fixedly connected to the movable block 20. The movable block 20 moves to the right in the first movable groove 18, thereby driving the cleaning ring 17 to move to the right. The outer diameter of the cleaning ring 17 matches the inner diameter of the tube body 1, thereby cleaning the inside of the tube body 1, eliminating adsorbed residue on the inner wall, ensuring the accuracy of the data, and at the same time extending the continuous running time and reducing the maintenance frequency.

[0021] Working Principle: In use, this invention firstly connects a connecting seat 10 threaded to the left side of the pipe body 1. A distribution chamber 9 is fixedly connected to the left side of the connecting seat 10. Seven sets of sampling heads 12 are located on the left side of the distribution chamber 9, enabling simultaneous sampling of flue dust at different locations in the flue. This avoids single-point sampling deviations caused by uneven airflow distribution, thus more accurately reflecting the overall emission concentration and improving the accuracy, reliability, and efficiency of the sampling data. Secondly, the sample enters the pipe body 1 through the sampling heads 12. A screen 14 is installed inside the pipe body 1. Large particles such as combustion residue, metal fragments, and fibers may be mixed in with the flue gas. These substances impact the screen 14. After 4, the slag falls from the slag outlet 15 into the slag collection bucket 16 below, thus preventing it from entering the subsequent sampling system and causing subsequent pipeline blockage or filter membrane damage. At the same time, by manually turning the two sets of second handles 22, the second handles 22 drive the connecting rod 21 to move to the right in the second movable groove 19. The right side of the connecting rod 21 is fixedly connected to the movable block 20. The movable block 20 moves to the right in the first movable groove 18, thereby driving the cleaning ring 17 to move to the right. The outer diameter of the cleaning ring 17 matches the inner diameter of the pipe body 1, thereby cleaning the inside of the pipe body 1, eliminating adsorbed residue on the inner wall, ensuring the accuracy of the data, and at the same time extending the continuous running time and reducing the maintenance frequency.
