Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen content detection technology for sintering waste gas, specifically to a rapid detection device for oxygen content in sintering machine wind box waste gas. Background Technology
[0002] In the detection of oxygen content in the flue gas from the sintering machine, oxygen content analysis is crucial because it not only relates to the actual emissions of the enterprise but also to the air leakage rate of the sintering machine. Previously, measurements were taken by opening the eight bolts at the opening, inserting the measuring tube, and then plugging the surrounding area with rags to prevent drafts. This method was prone to errors, resulting in unstable data that affected data analysis and failed to accurately reflect the actual situation.
[0003] Therefore, there is an urgent need to design a rapid oxygen content detection device for sintering machine exhaust gas to solve the problems of large measurement errors and inaccurate data due to environmental influences. Utility Model Content

The connecting end plate is installed on the exhaust gas outlet, and one end of the exhaust gas pipe is connected to the center of the connecting end plate. The other end of the exhaust gas pipe is connected to the exhaust gas switch.
[0006] Specifically, the connecting end plate consists of two sealed flanges, flange one and flange two. Flange one is installed on the waste outlet, and flange two has an opening in the center. The opening is connected to the waste gas pipe, and a detection pipe passes through the opening.
[0007] Specifically, the detection tube is an exhaust gas oxygen content detection device. The detection tube passes through the exhaust gas switch and extends into the waste outlet through the exhaust gas pipe and the connecting end plate.
[0008] Specifically, one end of the exhaust pipe is welded to the opening, and the other end of the exhaust pipe is sealed to the air inlet of the exhaust switch.
[0009] Specifically, the exhaust gas switch is a ball valve, with one end of the exhaust gas switch inlet connected to the exhaust gas pipe and the exhaust gas switch outlet end equipped with a sealing cap.
[0010] Specifically, the sealing cap is made of leather, and the center of the sealing cap has an opening of the same size as the detection tube, which fits into the detection tube to seal it.
[0011] This utility model has the following beneficial effects:
[0012] The sintering machine exhaust gas oxygen content rapid detection device designed in this utility model achieves rapid detection, is inexpensive, has a simple structure, is easy for personnel to operate, and improves detection efficiency and stability. Attached Figure Description

[0015] The technical solutions of the present utility model will be described in further detail below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0016] Example 1:
[0017] like Figure 1 As shown, a rapid oxygen content detection device for exhaust gas from a sintering machine wind box includes a connecting end plate 1, an exhaust gas pipe 2, and an exhaust gas switch 3. The connecting end plate 1 is installed on the exhaust gas outlet 5, and one end of the exhaust gas pipe 2 is connected to the center of the connecting end plate 1. The other end of the exhaust gas pipe 2 is connected to the exhaust gas switch 3.
[0018] Connect the connecting end plate 1 of this device to the exhaust gas outlet 5 of the sintering machine's air box. The connecting end plate 1 consists of two sealed flanges, flange 1.1 and flange 1.2. Flange 1.1 is fitted onto the exhaust outlet, and flange 1.2 has an opening in its center. The opening connects to the exhaust gas pipe 2, through which the detection pipe 4 passes. The connecting end plate 1 is used to connect the exhaust gas outlet 5 to other components of this device. The connecting end plate 1 has a through hole, and the exhaust gas pipe 2 is welded to the right side of the connecting end plate 1. The exhaust gas pipe 2 is used to transport the exhaust gas from the exhaust gas outlet 5 to the exhaust gas switch 3. The right side of the exhaust gas pipe 2 is sealed to the exhaust gas switch 3. The exhaust gas switch 3 is equipped with a valve, which controls the emission of exhaust gas. When not in use, the outlet end of switch 3 is equipped with a plug to prevent air leakage. When in use, the outlet end of exhaust gas switch 3 is equipped with a sealing plate 3.1, which is made of leather material. The sealing plate 3.1 has a through hole in the middle to prevent exhaust gas from flowing out from other positions during testing and to prevent outside air from entering the pipeline and affecting the test results. The detection tube 4 is a long tube that is inserted into the through hole on the sealing plate 3.1. Due to the tight fit of the leather material, the detection tube 4 and the sealing plate 3.1 are closely fitted. After passing through the exhaust gas switch 3, the exhaust pipe 2, and the connecting end plate 1, the detection tube 4 extends directly into the exhaust gas outlet 5, with a complete seal to prevent non-detection air from entering and affecting the test results.
