[0002] When industrial waste gas is discharged, it is necessary to filter or neutralize the dust, impurities and other harmful substances in it before it can be discharged. Sampling and testing should be carried out at the discharge location to determine whether the discharged gas is qualified.
[0003] Utility model CN221964788U discloses a gas emission filtration device for environmental monitoring, including a fan. The fan's input end is connected to an input pipe, and its output end is connected to an output pipe. The output end of the output pipe is connected to a first connecting pipe via a flange, and the input end of the input pipe is connected to a second connecting pipe via a flange. A vibration filtration mechanism is installed inside the second connecting pipe. The vibration filtration mechanism includes a filter assembly and a vibration assembly. A dust discharge pipe is installed at the bottom of the second connecting pipe, and a dust discharge valve mechanism is installed inside the dust discharge pipe. This utility model, by setting up a filter assembly and a vibration assembly, allows the vibration assembly to strike the filter screen, causing vibration and dislodging dust and impurities adhering to the filter screen, thereby ensuring stable ventilation. When the filter screen becomes clogged, the vibration assembly facilitates more convenient maintenance.
[0004] Existing gas emission filtration devices are prone to filter screen damage, such as cracks and breaks, due to prolonged high-frequency vibration and impact. This can lead to filter failure, requiring downtime for replacement and repair, which affects the continuity and stability of industrial production and increases the company's operating and time costs. Therefore, there is a problem with easily damaged filter screens. Utility Model Content

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0027] Example 1
[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a gas emission filtration device for environmental monitoring, including a fan 1. A maintenance mechanism 2 is fixedly connected to the air inlet of the fan 1. A filter mechanism 3 is fixedly connected to the outer surface of the maintenance mechanism 2. The filter mechanism 3 includes a fixing frame 305 fixedly connected to the inner wall of the air inlet duct 202. A rotating shaft 307 is rotatably connected to the outer surface of the fixing frame 305. A turbine fan 306 is fixedly connected to one end of the rotating shaft 307. A cleaning rod 309 is fixedly connected to the outer surface of the rotating shaft 307. The filter mechanism 3 also includes a connecting frame 302 fixedly connected to the lower surface of the air inlet duct 202.
[0029] Specifically, a filter plate 308 is fixedly connected to the outer surface of the fixed frame 305. The outer surface of the filter plate 308 is slidably connected to the outer surface of the cleaning rod 309. An electric telescopic rod 303 is fixedly connected to the outer surface of the connecting frame 302. A sealing plate 304 is fixedly connected to the output end of the electric telescopic rod 303. The sealing plate 304 is slidably connected to the inner wall of the connecting frame 302. The two ends of the connecting frame 302 are respectively set on both sides of the filter plate 308. A filter screen 310 is fixedly connected to the inner wall of the connecting frame 302. A cleaning plate 301 is slidably connected to the inner wall of the connecting frame 302. One end of the cleaning plate 301 passes through the outer surface of the connecting frame 302 and is fixedly connected to a handle. The friction between the cleaning rod 309 and the filter plate 308 is small, so the filter plate 308 will not be worn.
[0030] The blower 1 is then started, drawing gas out of the inlet duct 202. This causes the turbine fan 306 to rotate under the influence of the airflow, moving impurities toward the edge of the filter plate 308. Then, the electric telescopic rod 303 is started, and its output end drives the sealing plate 304 to slide. Exhaust gas can flow into the blower 1 through the connecting frame 302, allowing impurities at the edge of the filter plate 308 to enter the connecting frame 302. The sealing plate 304 is then reset, and the cleaning plate 301 is pulled, causing it to slide out from the inner wall of the connecting frame 302, thus facilitating the cleaning of impurities within the connecting frame 302.
[0031] Example 2
[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The maintenance mechanism 2 includes an air inlet pipe 202 fixedly connected to the air inlet of the fan 1. A fixing block 206 is fixedly connected to the outer surface of the air inlet pipe 202. A sealing shell 201 is rotatably connected to the outer surface of the fixing block 206. The outer surface of the sealing shell 201 is in contact with the outer surface of the air inlet pipe 202, and a sealing gasket 203 is fixedly connected to the inner side of the sealing shell 201.
[0033] Specifically, the outer surface of the air inlet duct 202 is fixedly connected to a fixing block 206, and the outer surface of the sealing shell 201 is threadedly connected to a fastening bolt 204, with the other end of the fastening bolt 204 threadedly connected to the outer surface of the fixing block 206.
[0034] Further rotate the fastening bolt 204 to separate the fastening bolt 204 from the fixing block 206, and then pull the sealing shell 201 to rotate on the outer surface of the fixing block 206, so that the sealing gasket 203 slides out from the outer surface of the air inlet duct 202, thereby facilitating the maintenance of the turbo fan 306 and the filter plate 308.
[0035] Working principle: By starting the fan 1, the fan 1 draws the gas out of the inlet duct 202, causing the turbofan 306 to rotate under the action of the airflow. The rotation of the turbofan 306 drives the rotating shaft 307 to rotate, which in turn drives the cleaning rod 309 to rotate. The rotation of the cleaning rod 309 facilitates the cleaning of impurities on the outer surface of the filter plate 308, causing the impurities to move towards the edge of the filter plate 308. Then, the electric telescopic rod 303 is activated. The output end of the electric telescopic rod 303 drives the sealing plate 304 to slide, and the exhaust gas can flow into the fan 1 through the connecting frame 302. The filter screen 310 prevents impurities from entering the fan 1, thereby making the filter plate... Impurities at the edge of 308 can enter the connecting frame 302. Then, the sealing plate 304 is reset, and the cleaning plate 301 is pulled to slide out from the inner wall of the connecting frame 302, which facilitates cleaning of impurities in the connecting frame 302. When maintenance is required, the fastening bolt 204 is rotated to separate the fastening bolt 204 from the fixing block 206. Then, the sealing shell 201 is pulled to rotate on the outer surface of the fixing block 206, and the sealing gasket 203 slides out from the outer surface of the air inlet duct 202, which facilitates maintenance of the turbine fan 306 and the filter plate 308, and also facilitates protection of the filter plate 308.
