Technical Field
[0001] The utility model relates to the technical field of tail gas monitoring, in particular to a recovery type tail gas emission detection mechanism. Background Art
[0002] At present, there are many types of non-road mobile machinery diesel vehicles with broad application fields. They occupy an important position in my country's national economy. The main supporting industries include agricultural machinery, construction machinery and generator sets. While they provide people with convenient life, they also emit a lot of pollutants. These pollutants will seriously affect the environment in which humans live. In order to strengthen the environmental supervision of non-road mobile machinery and further improve the air environment, it is necessary to test the exhaust gas of non-road mobile vehicles. Currently, it is suitable for exhaust emission testing institutions on the market, but there are still some shortcomings.
[0003] For example, in actual use, general exhaust emission detection mechanisms detect exhaust gas by directly absorbing exhaust gas through monitoring tools. In this process, it is necessary to pull the connecting pipe to receive the exhaust gas. Generally, the detection device does not have a stable setting for the detection mechanism, which can easily cause exhaust gas leakage. At the same time, the exhaust gas is discharged after detection, which greatly wastes energy. In addition, when absorbing the exhaust gas, the connecting pipe cannot be accurately aligned to the appropriate position, and it is troublesome to adjust the mobile and fixed detection device, which will result in waste of manpower and other problems. Therefore, we propose a recovery type exhaust emission detection mechanism to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-4 The utility model provides a technical solution: a recovery type exhaust emission detection mechanism, including: a non-slip foot pad 1, a support rod 2, an automatic telescopic rod 3, a connecting rod 4, a support rod 5, a first bevel gear 6, a second bevel gear 7, a rotating handle 8, a support frame 9, a bolt 10, a fixing ring 11, a detection device 12, a sealing ring 13, a connecting hose 14, a pipeline 15, a purification box 16, a filter screen 17, an adsorbent bed 18, a partition plate 19, a water cooling circulation machine 20, an exhaust fan 21 and a recovery box 22.
[0025] like Figure 1 , Figure 2 and Figure 4As shown in the figure, by determining that the connecting hose 14 is aligned with the exhaust port, the anti-skid pad 1 is placed on the ground, and then the support rod 2 outside the automatic telescopic rod 3 is rotated, and the support rod 2 is connected to the anti-skid pad 1, so that the support rod 2 and the anti-skid pad 1 are supported, and then the support rod 5 set at the same angle outside the connecting rod 4 is supported inside the first bevel gear 6, so that the anti-skid pad 1 and the support rod 2 are more stable, and then the support rod 5 and the first bevel gear 6 are fixed by bolts 10, so that the automatic telescopic rod 3 in the support rod 2 is supported, and the automatic telescopic rod 3 A support frame 9 is connected above the output end, and a fixing ring 11 is fixed to the upper inner side of the support frame 9 by a bolt 10. The front and rear sides of the fixing ring 11 firmly clamp the detection device 12, so the anti-slip foot pad 1, the support rod 2, the automatic telescopic rod 3, the connecting rod 4, the support rod 5, the support frame 9, the bolt 10 and the fixing ring 11 fix the detection device 12, so that the detection device 12 remains stable during operation. In addition, the automatic telescopic rod 3 is opened, and the automatic telescopic rod 3 can push the output end to move upward, so that the upper and lower heights of the detection device 12 can be adjusted.
[0026] like Figure 1 and Figure 3 As shown in , after the detection device 12 is manually fixed, the connecting hose 14 is aligned with the exhaust port to prepare for absorption detection. The detection device 12 and the connecting hose 14 are threadedly connected and a sealing ring 13 is also provided at the connection, so that the sealing of the entire test process is very good. In addition, because the connecting hose 14 is manually fixed, there may be some deviations in the alignment of the connecting hose 14 with the exhaust port. If the detection device 12 and the entire stabilizing mechanism are lifted again, it will be more troublesome. At this time, you can hold the rotating handle 8 by hand. The left side of the rotating handle 8 is connected to the second bevel gear 7. When holding the rotating handle 8 and rotating the rotating handle 8, the rotating handle 8 connected to the second bevel gear 7 will also rotate, and the upper left side of the second bevel gear 7 is meshed with the first bevel gear 6. The first bevel gear 6 is connected to the support frame 9. The rotation of the second bevel gear 7 will cause the first bevel gear 6 and the support frame 9 to rotate together. The detection device 12 and the connecting hose 14 are connected to the support frame 9, so the position of the rotating support frame 9 can adjust the position of the connecting hose 14, so that the connecting hose 14 can be more accurately aligned with the exhaust port.
[0027] By turning on the vacuum pump 21, when the connecting hose 14 contacts and absorbs the exhaust gas, the exhaust gas will first enter the detection device 12 for inspection, and then the exhaust gas detected in the detection device 12 will be transmitted to the inside of the purification box 16 by the pipeline 15. The exhaust gas will first pass through the filter screen 17 at the lower right of the purification box 16. The filter screen 17 will filter out large carbon particles in the exhaust gas and pre-treat the exhaust gas. The treated exhaust gas will then be transmitted to the left side of the filter screen 17 and pass through the adsorbent bed 18. The adsorbent bed 18 has two layers. The adsorbent bed 18 also has a developed pore structure, which can adsorb harmful substances in the exhaust gas twice. The exhaust gas after removing the harmful substances flows into the left side of the purification box 16 from the outlet in the middle of the partition plate 19 on the left side of the adsorbent bed 18. The water-cooled circulation machine 20 is turned on, and the water-cooled circulation machine 20 can transmit cold air to the left side of the purification box 16, so that the exhaust gas can be quickly cooled down and further meet the recycling standards. Then, the treated off-road vehicle exhaust gas is discharged into the interior of the recovery box 22 through the exhaust fan 21, and can be recycled and reused.
