[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings. Example 1

[0016] like Figure 1-4As shown, this utility model provides a technical solution: a filter material efficiency testing device based on sodium flame method, including a testing chamber 1, a mixing chamber 2 fixedly installed on the upper part of the testing chamber 1, an upper flow channel 4 connected to the left side of the testing chamber 1, a lower flow channel 5 connected to the right side of the testing chamber 1, a sodium flame detector body 6 connected to the outside of the upper flow channel 4 and the lower flow channel 5 via a connecting pipe, a filter pipe 7 connected to the bottom end of the lower flow channel 5, and a connecting assembly 3 located on one side of the testing chamber 1. The connecting assembly 3 includes a filter mechanism 31 located on one side of the testing chamber 1, a stirring mechanism 32 located on the upper part of the testing chamber 1, and a first valve located near the end of the upper flow channel 4 and the lower flow channel 5. The top end of the upper flow channel 4 is connected to the mixing chamber 2 for mixing. The upper and side parts of the box 2 are connected by feed pipes, and the outer ends of the feed pipes are equipped with second valves. The filter mechanism 31 includes an installation groove inside the filter tube 7, and an installation frame 311 is inserted into the installation groove. The filter plate 312 and the activated carbon adsorption plate 313 are fixedly installed inside the installation frame 311. The upper part of the installation frame 311 has a slot 314. The filter tube 7 has a movable groove 316. The inner wall of the movable groove 316 is slidably connected to a movable block 317. The bottom of the movable block 317 is fixedly connected to a sloped locking block 318. The inner wall of the movable groove 316 is fixedly connected to a first spring 319. The outer side of the inner wall of the movable groove 316 has a movable hole 3110. The movable hole 3110 is movably connected to a pull rod. The inner wall of the filter tube 7 is fixedly connected to a sealing ring 315.

[0017] In this embodiment, the inclined plate 318 is movably connected to the movable groove 316 and the slot 314. The sealing ring 315 is located in the gap between the mounting groove and the mounting frame 311. Through the cooperation of the mounting frame 311, the filter plate 312, the activated carbon adsorption plate 313, the slot 314, the sealing ring 315, the movable groove 316, the movable block 317, the inclined plate 318, the first spring 319, and the movable hole 3110, the exhaust gas can be filtered, thereby preventing the exhaust gas from being directly emitted and polluting the external environment. In addition, the mounting frame 311 is easy to disassemble manually, which facilitates the manual cleaning or replacement of the filter plate 312 and the activated carbon adsorption plate 313, increasing the applicability of the device.

[0018] Furthermore, one end of the first spring 319 is fixedly connected to the movable block 317, and the outer side of the movable block 317 is fixedly connected to the pull rod.

[0019] When exhaust gas is discharged outward through the mounting frame 311, it can be filtered by the filter plate 312 and the activated carbon adsorption plate 313, thus preventing the exhaust gas from being directly discharged and polluting the external environment. Furthermore, when it is necessary to disassemble the mounting frame 311, simply hold the lever and pull the movable block 317, which will cause the inclined locking block 318 fixedly connected to the bottom of the movable block 317 to separate upward from the locking groove 314. Then the mounting frame 311 can be taken out, which makes it convenient for manual cleaning or replacement of the filter plate 312 and the activated carbon adsorption plate 313, thus facilitating subsequent use. Example 2

[0020] Based on Example 1, a preferred embodiment of the filter material efficiency testing device based on the sodium flame method provided by this utility model is as follows: Figures 1 to 4 As shown: The stirring mechanism 32 includes a motor 321 fixedly mounted on the upper part of the mixing box 2 via a bracket. A first rotating shaft 322 is fixedly connected to the output end of the motor 321. A stirring rod 323 is fixedly connected to the outer wall of the first rotating shaft 322. A rotating rod 324 is fixedly connected to the outer wall of the bottom end of the first rotating shaft 322. A second rotating shaft 325 is rotatably connected to one end of the rotating rod 324 via a bearing. A conveying blade 326 is fixedly connected to the outer wall of the second rotating shaft 325. A gear 327 is fixedly connected to the bottom end of the second rotating shaft 325. A gear ring 328 is fixedly connected to the inner wall of the mixing box 2.

[0021] In this embodiment, the first rotating shaft 322 is rotatably connected to the mixing box 2 via a bearing, and the gear 327 is meshed with the gear ring 328. Through the cooperation of the motor 321, the first rotating shaft 322, the stirring rod 323, the rotating rod 324, the second rotating shaft 325, the conveying blade 326, the gear 327, and the gear ring 328, the atomized droplets can be fully stirred and mixed with the air to form an aerosol with stable concentration and particle size distribution, which makes subsequent detection operations easier and further increases the applicability of the device.

[0022] Furthermore, there are two rotating rods 324, symmetrically distributed on both sides of the first rotating shaft 322.

[0023] In use, the device atomizes a sodium chloride solution and introduces it into the mixing chamber 2, while simultaneously introducing air into the mixing chamber 2. Then, a motor 321 drives the first rotating shaft 322 to rotate, which in turn causes the stirring rod 323, fixedly connected to the outer wall of the first rotating shaft 322, to rotate synchronously. This ensures thorough mixing of the atomized solution with the air. Furthermore, the rotation of the first rotating shaft 322 causes the rotating rod 324, also fixedly connected to the outer wall of the first rotating shaft 322, to drive the second rotating shaft 325 to rotate synchronously. Additionally, due to the interaction between gear 327 and gear... The engagement of ring 328 allows the conveying blades 326, which are fixedly connected to the outer wall of the second rotating shaft 325, to rotate on their own axis while revolving around the revolution. This allows the material in the upper part of the mixing box 2 to be conveyed downwards, resulting in better mixing and the formation of an aerosol with stable concentration and particle size distribution. This aerosol is then introduced into the upper flow channel 4 and then into the detection box 1. The filter material sample is placed in the detection box 1 manually, and with the cooperation of the sodium flame detector body 6, the filter material can be tested, increasing the applicability of the device.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
