Abstract
Description
Technical Field
[0001] This utility model relates to a sampler, and more particularly to a sampling structure for a flue gas analyzer. Background Technology
[0002] A flue gas analyzer is a professional environmental monitoring device used to monitor the concentration of particulate matter (dust) and gaseous pollutants (flue gas) in combustion processes or industrial emissions. It is mainly used in environmental monitoring and industrial process control. Its core function is to provide accurate data support for assessing pollution source emissions compliance and optimizing the efficiency of pollution control equipment through sampling and analysis.
[0003] Before analyzing flue gas and dust, a flue gas analyzer needs to sample the flue gas and dust. Traditional sampling equipment includes a sampling tube and a filter cartridge. One end of the sampling tube is connected to the flue gas environment, and the other end is connected to the filter cartridge. The flue gas and dust spontaneously enter the sampling tube and then the filter cartridge. Once a certain amount of flue gas and dust has accumulated in the filter cartridge, it is removed from the sampling tube and sent to the analyzer for analysis. However, this spontaneous entry of the flue gas and dust into the sampling tube is time-consuming and results in low sampling efficiency. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sampling structure for a flue gas and dust analyzer.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sampling structure for a flue gas and dust analyzer, comprising:

[0007] The second sampling tube has a second opening, a third opening, and a second cavity, both of which are connected to the second cavity; and the second opening and the third opening of the second sampling tube are located in the first cavity of the first sampling tube, and both of which are connected to the first cavity.
[0008] A sampling component, wherein the sampling component is disposed in the second cavity;
[0009] A drive motor is connected to the sampling component, thereby driving the sampling component to rotate in the second cavity. When the sampling component rotates, smoke and dust enter the second cavity from the second opening and the third opening of the second sampling tube.
[0010] Preferably, the sampling component includes a rotating rod and a helical blade. The helical blade is fixedly mounted on the rotating rod. The drive motor has a rotating shaft, and the rotating shaft and the rotating rod are connected by a coupling, so that the drive motor drives the rotating rod to rotate, thereby driving the helical blade to rotate.

[0013] Preferably, it further includes a connecting sleeve, a bearing, and a base. The bearing is mounted on the connecting sleeve. The rotating rod and the helical blade of the sampling assembly are fixedly mounted together with the base. The base is mounted together with the bearing, so that the base can rotate relative to the connecting sleeve.

[0028] Please refer to Figure 1-6 This application provides a sampling structure for a flue gas and dust analyzer (hereinafter referred to as "the sampling structure"), which includes:
[0029] A first sampling tube 1 has a first opening 101 and a first cavity 100, and the first opening 101 and the first cavity 100 are connected.
[0030] The second sampling tube 8 has a second opening 81, a third opening 82, and a second cavity 80. The second opening 81 and the third opening 82 are both connected to the second cavity 80. The second opening 81 and the third opening 82 of the second sampling tube 8 are located in the first cavity 100 of the first sampling tube 1, and the second opening 81 and the third opening 82 are both connected to the first cavity 100.
[0031] Sampling component 9, wherein the sampling component 9 is disposed in the second cavity 80;
[0032] A drive motor 2 is connected to the sampling component 9, thereby driving the sampling component 9 to rotate within the second cavity 80. When the sampling component 9 rotates, smoke and dust enter the second cavity 80 through the second opening 81 and the third opening 82 of the second sampling tube 8. Thus, when the first sampling tube 1 is placed in a smoke and dust environment, smoke and dust enter the cavity 100 of the first sampling tube 1 through the first opening 101. Activating the drive motor 2 causes the sampling component 9 to rotate within the second cavity 80 of the second sampling tube 8, thereby allowing smoke and dust to enter the second cavity 80 through the second opening 81 and the third opening 82 of the second sampling tube 8.
[0033] In some embodiments of this application, please refer to Figure 1-6 The sampling assembly 9 includes a rotating rod 91 and a spiral blade 92. The spiral blade 92 is fixedly mounted on the rotating rod 91. The drive motor 2 has a rotating shaft 200, and the rotating shaft 200 and the rotating rod 91 are connected by a coupling 14, so that the drive motor 2 drives the rotating rod 91 to rotate, thereby driving the spiral blade 92 to rotate. In this way, when the spiral blade 92 rotates, it draws the smoke and dust located at the second opening 81 and the third opening 82 of the second sampling tube 8 into the second cavity 80 of the second sampling tube 8.
[0034] In some embodiments of this application, please refer to Figure 1-6 The sampling structure further includes a first covering sleeve 11, which is fitted onto the second sampling tube 8. The first covering sleeve 11 has a fourth opening 110. The second sampling tube 8 is provided with an air outlet 83, and the air outlet 82 communicates with the second cavity 80. When the first covering sleeve 11 is fitted onto the second sampling tube 8, the fourth opening 110 of the first covering sleeve 11 is aligned with the air outlet 83 of the second sampling tube 8 and overlaps vertically, and the fourth opening 110 communicates with the air outlet 82. In this way, the smoke and dust are drawn into the second cavity 80 of the sampling tube 8 by the sampling component 9, and then flow out from the air outlet 82 of the sampling tube 8.
[0035] In some embodiments of this application, please refer to Figure 1-6The sampling structure further includes a second covering sleeve 3 and a three-way pipe 4. The second covering sleeve 3 is fitted onto the second sampling tube 8, and the three-way pipe 4 is fitted onto the first covering sleeve 11, with the fourth opening 110 of the first covering sleeve 11 communicating with the three-way pipe 4. The second covering sleeve 3 and the three-way pipe 4 are joined together. In this application, the second covering sleeve 3 and the second sampling tube 8 are fitted together with an interference fit, so that there is no gap between the inner wall of the second covering sleeve 3 and the outer surface of the second sampling tube 8, thereby preventing smoke and dust from entering the gap between the second covering sleeve 3 and the second sampling tube 8. Similarly, the three-way pipe 4 and the first covering sleeve 11 are also installed together with an interference fit, so that smoke and dust will not enter the gap between the three-way pipe 4 and the first covering sleeve 11.
[0036] In some embodiments of this application, please refer to Figure 1-6 The sampling structure also includes a connecting sleeve 5, a bearing 13, and a base 12. The bearing 13 is mounted on the connecting sleeve 5. The rotating rod 91 and the spiral blade 92 of the sampling assembly 9 are both fixedly mounted to the base 12. The base 12 is mounted together with the bearing 13, thereby allowing the base 12 to rotate relative to the connecting sleeve 5. The base 12 extends into the second cavity 80 of the second sampling tube 8, and the base 12 can rotate within the second cavity 80 of the second sampling tube 8. Thus, under the drive of the drive motor 2, the sampling assembly 9 can rotate within the second sampling tube 8.
[0037] In some embodiments of this application, please refer to Figure 1-6 The sampling structure also includes a clamp 7. The second covering sleeve 3 has a second mating part 31, and the tee pipe 4 has a third mating part 41.

[0038] In some embodiments of this application, please refer to Figure 1-6 The tee pipe 4 has a fourth mating part 42, and the connecting sleeve 5 has a fifth mating part 51. The fourth mating part 42 and the fifth mating part 51 are mated together, and the clamp 7 wraps and fixes the fourth mating part 42 and the fifth mating part 51, thereby connecting the tee pipe 4 and the connecting sleeve 5 together.

The sixth docking part 61 and the seventh docking part 43 are docked together, and the clamp 7 wraps and fixes the seventh docking part 43 and the sixth docking part 61, thereby connecting the tee pipe 4 and the connecting pipe 6 together.
[0040] The working principle of this application is as follows: the sampling structure is placed in the sampling environment of dust and flue gas. The dust and flue gas enter the first cavity of the first sampling tube. The drive motor is started, and the drive motor drives the sampling component to rotate. The sampling component draws the dust and flue gas in the first cavity of the first sampling tube into the second cavity of the second sampling tube. Then, the dust and flue gas in the second cavity flows from the outlet on the second sampling tube into the three-way pipe. The dust and flue gas in the three-way pipe flows from the connecting pipe into the dust and flue gas analyzer.
[0041] The sampling structure of the flue gas analyzer provided in this application has the advantages of simple structure and easy assembly. Given that it is equipped with a drive motor, a sampling component, and a second sampling tube, the drive motor drives the sampling component to rotate in the second cavity of the second sampling tube, thereby transferring the flue gas located at the second opening and the third opening of the second sampling tube into the second cavity, and finally flowing into the connecting pipe. Compared with the prior art where the flue gas naturally enters the second sampling tube, the sampling structure provided in this application speeds up the sampling of flue gas and improves the sampling efficiency.
