Description

Technical Field

[0001] The utility model belongs to the technical field of salt spray test, in particular to a composite salt spray corrosion test box. Background Art

[0002] Salt spray test is a commonly used environmental test method used to evaluate the corrosion resistance of materials or coatings in salt spray environment. It simulates the salt spray corrosion in the marine environment. By exposing the sample to the salt spray spray environment, the corrosion degree of the sample is observed and evaluated. Most of the existing salt spray corrosion test boxes fasten the test samples in the test box by bolts. The bolt fixing method is cumbersome and time-consuming, which invisibly prolongs the salt spray corrosion test cycle. In addition, most of the filter boxes set in the existing salt spray corrosion test boxes do not have the function of anti-clogging. When in use, the filter mesh may be blocked, so that the air cannot enter the test box, resulting in the inability of the salt spray to spread evenly and adhere to the various surfaces of the test sample, affecting the accuracy of the test.

[0003] Although the above device has an anti-clogging function during use, it still has certain shortcomings during use. First, its salt spray nozzle is located on one side of the inside of the test chamber. At this time, during the spraying of salt spray, the salt spray content on the side of the test chamber close to the salt spray nozzle must be higher than the other side, so that the salt spray content contacted by the surfaces of parts on both sides of the equipment during the test is different. It can be seen that the existing equipment has certain shortcomings as a whole during use, and there are differences in detection accuracy, so it needs to be improved. Utility Model Content

At this time, the circular plate is positioned, and the net disk placed on the top of the circular plate can be fixed. When disassembly is required, just start the telescopic cylinder to reset and quickly disassemble and assemble the net disk, which is convenient for the equipment to flexibly replace the net disk, improving the convenience and efficiency of the test.

[0017] Third, when the suction fan is running, the induced draft scoop can suck out the air inside the box, and the air with salt mist enters the filter box. The activated carbon purification core inside the filter box filters and purifies the salt mist, and the filtered and purified salt mist is discharged through the suction fan, so that the whole equipment can have a strong purification effect and avoid harm to the surrounding environment. The interior of the box is heated by the electric heating wire. The temperature increase can increase the reaction rate of the workpiece surface, thereby improving the test efficiency. At the same time, it is also convenient to detect the conditions of workpieces at different temperatures, thereby improving the detection effect of this equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] By setting up the filtering mechanism 9, during the use of the device, the suction fan 91 can be started to operate, and the suction fan 91 can be operated to make the induced draft scoop 92 suck out the air inside the box 2. At this time, the air with salt mist enters the interior of the filter box 93, and the salt mist is filtered and purified by the activated carbon purification core 94 inside the filter box 93.
