[0002] A salt spray corrosion test chamber is a testing device used to simulate salt spray corrosion conditions in natural environments. It is widely used in materials science, electronics, automotive manufacturing, aerospace, and other fields. Its main purpose is to evaluate the corrosion resistance of materials and their protective layers, ensuring that products have sufficient corrosion resistance in real-world environments. Its working principle involves atomizing salt water into tiny droplets (i.e., salt spray) and spraying it into a sealed test chamber to simulate the corrosive effects of marine or high-salt-spray environments on materials.

[0003] During salt spray testing, exhaust gases containing salt spray particles, water vapor, and acidic gases are generated. Direct release of these gases into the environment can harm the air, equipment, and the health of operators. To avoid these problems, exhaust gas treatment components are typically installed. These components usually include filter and purification modules. After prolonged use, these components require replacement, such as disassembling and replacing the filters and replacing the purification materials within the purification modules. Replacement is often cumbersome, requiring disassembly and opening of the test chamber to separately remove and replace the filter and purification modules, involving the removal of numerous screws and resulting in low efficiency. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] according to Figure 1-5 As shown: This utility model provides a salt spray corrosion test chamber with exhaust gas treatment function: it includes a chamber body 1, a sealing cover 2 on the chamber body 1, and a control panel 3 on one side of the chamber body 1; a salt spray nozzle 8 is provided on the chamber body 1, and the salt spray nozzle 8 is located inside the sealing cover 2; a slot 7 is provided on the chamber body 1, and a locking block 6 is fixedly provided at the bottom of the sealing cover 2 to insert into the slot 7, facilitating the disassembly and installation of the sealing cover 2. It also includes:

[0022] The enclosure 1 includes a treatment tank 10, a filter assembly, and a purification assembly. The treatment tank 10 is located inside the enclosure 1 and is connected to a sealing cover 2 via a waste discharge pipe 9. The filter assembly and purification assembly are located within the treatment tank 10, with the purification assembly positioned below the filter assembly. A sealing groove 17, connected to the treatment tank 10, is located at the bottom of the enclosure 1. The purification assembly is slidably disposed within the treatment tank 10, and a sealing plate 12, fixedly connected to the purification assembly, is located within the sealing groove 17. An electric telescopic rod 11 is located at the bottom of the enclosure 1, with its working end fixedly connected to the sealing plate 12. The filter assembly is horizontally slidably disposed within the treatment tank 10, and the purification assembly secures the filter assembly. An outlet pipe 5, connected to the treatment tank 10, is located on one side of the enclosure 1. An outlet pump 4, corresponding to the outlet pipe 5, is located on the outer wall of the enclosure 1, providing power for the treatment and discharge of waste gas.

[0023] like Figure 4 , 5 As shown, the filter assembly includes a support plate 15 and a filter screen 14; the support plate 15 is horizontally slidably inserted into the treatment tank 10, and the filter screen 14 is disposed on the support plate 15; a pull plate 16 is disposed on the outside of the housing 1, a sealing gasket is disposed on the pull plate 16, and the pull plate 16 is fixedly connected to the support plate 15.

[0024] like Figure 4 , 5 As shown, the purification assembly includes a carrier box 13 containing activated carbon, and the carrier box 13 is located below the support plate 15. The carrier box 13 is slidably disposed within the treatment tank 10, and is fixedly connected to the sealing plate 12 via a connecting rod. When the sealing plate 12 is removed, the carrier box 13 can be removed along with it, thereby reducing the number of operation steps.

[0025] A rod 19 is fixedly connected to the carrier box 13. The bottom of the support plate 15 has a corresponding insertion hole 18, and the rod 19 is inserted into the insertion hole 18. The support plate 15 is fixed by the rod 19, so that when the carrier box 13 is disassembled, the rod 19 can disengage from the insertion hole 18 and contact the fixation of the support plate 15, which facilitates the disassembly of the filter screen 14.

[0026] The principle of this utility model

[0027] like Figure 3 As shown, during the salt spray test, the test sample is placed on the chamber 1, the locking block 6 is engaged with the locking slot 7, the test sample is sealed using the sealing cover 2, and salt spray is sprayed into the sealing cover 2 using the salt spray nozzle 8. Figure 4 As shown, during the test, the outflow pump 4 is started. Under the suction of the outflow pump 4, the waste gas in the sealing cover 2 enters the treatment tank 10 through the waste discharge pipe 9. After being filtered by the filter screen 14, it enters the carrier box 13. After being adsorbed by the activated carbon in the carrier box 13, it flows out from the outflow pipe 5.

[0028] With prolonged use of the treatment tank 10, the filter screen 14 needs to be replaced or cleaned, and the activated carbon in the carrier box 13 also needs to be replaced; such as Figure 4 As shown, activating the electric telescopic rod 11 moves the sealing plate 12 downwards, thereby moving the sealing plate 12 and the carrier box 13 downwards, causing the carrier box 13 to detach from the treatment tank 10, facilitating the replacement of the activated carbon inside the carrier box 13; simultaneously, as Figure 5 As shown, when the carrier box 13 moves down, the insertion rod 19 disengages from the insertion hole 18, releasing the fixation on the support plate 15. The operator can then operate the pull plate 16 to directly pull out the support plate 15 along with the filter screen 14. Therefore, this application enables quick and efficient disassembly of the carrier box 13 and the filter screen 14, facilitating the maintenance and replacement of the treatment structure within the treatment tank 10. During installation, the filter screen 14 needs to be installed first. The support plate 15 with the filter screen 14 is directly inserted into the treatment tank 10. Then, the electric telescopic rod 11 is activated, causing the sealing plate 12 and the carrier box 13 to rise. The insertion rod 19 on the carrier box 13 is inserted into the insertion hole 18 to fix the support plate 15. Simultaneously, when the installation of the carrier box 13 is quickly completed, the sealing plate 12 can also seal the sealing groove 17, achieving three benefits in one go and resulting in high operational efficiency.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
