Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of salt spray testing equipment technology, and more specifically, to a salt spray testing equipment for enamel pots. Background Technology
[0002] A salt spray tester is a device used to simulate a salt spray environment and test the corrosion resistance of materials. It sprays a system of tiny salt droplets onto the sample to simulate the destructive effects of marine climates, thereby detecting the sample's corrosion resistance. Salt spray testers are widely used in electronics, automotive, aerospace, and other fields, and are suitable for testing industrial products such as galvanized products, coatings, electronic and electrical components, and zippers and buttons.
[0003] The working principle of the salt spray tester is to use the high-speed airflow generated by the high-speed injection of compressed air from the nozzle to form a negative pressure above the water suction pipe. Under the action of atmospheric pressure, the salt solution rises rapidly along the water suction pipe to the nozzle, is atomized by the high-speed airflow, and is sprayed onto the conical mist distributor at the top of the spray pipe before drifting out of the spray nozzle, spreading into the test chamber to form a diffused state, and naturally falling onto the test specimen to carry out the salt spray corrosion resistance test.
[0004] During the production of enamel pots, various tests are required, one of which is the salt spray test for the surface treatment. However, current salt spray testing machines are not convenient for supporting the enamel pots, resulting in some surfaces being unable to be tested. Other tools are needed to assist, making the operation cumbersome and requiring a long adjustment time for each test.

[0050] For example, such as Figure 2 As shown, bracket 6-10 has a disc-shaped structure and a grid-like hollow structure on its surface.
[0051] In some examples, the disc-shaped structure, combined with multiple bosses 6-11, supports the enamel pot and keeps it stable, while the openwork structure allows liquid to pass through.
[0052] For example, such as Figure 2 As shown, the spray pipe 5 has two liquid outlets, and both liquid outlets of the spray pipe 5 have a certain tilt angle.
[0053] In some examples, the liquid can be sprayed onto both the inner and outer surfaces simultaneously through two outlets.
[0054] For example, such as Figure 4 As shown, slot 6-9 has a polygonal cross-section.
[0055] In some examples, the polygonal structure allows the bracket 6-10 to remain fixed after insertion, enabling it to rotate stably and synchronously with the vertical axis 6-8.
[0056] For example, such as Figure 4 As shown, the inner surface of the collection tank 7-1 is an inclined structural surface, and the concentration cover 7-2 is located at the lowest plane inside the collection tank 7-1.
[0057] In some examples, the inclined structural surface facilitates the flow of all the brine to the concentration hood 7-2.
[0058] For example, such as Figure 4 As shown, the movable seat 6-4 and the inner surface of the notch 4, as well as the top cover 2 and the outer cover 6-5, are sealed and slidingly fitted.
[0059] In some examples, a sealant is used to keep the interior sealed, ensuring accurate test results.
[0060] When testing is required, place the enamel pot on the bracket 6-10, supported by the boss 6-11. Start the drive screw 6-3 to control the moving seat 6-4 to move into the notch 4. After moving to the innermost position, the outer cover 6-5 aligns with the top cover 2. Start the drive motor 6-7 to control the fixed shaft to drive the enamel pot to rotate at a constant speed. Then start the spray device 3 to cover the inner and outer surfaces of the enamel pot with salt water through the spray pipe 5. Observe the test through the observation window 6-6. Finally, open and remove the enamel pot to check the test results.
[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it.
