Description

Technical Field

[0001] The invention relates to the technical field of salt spray corrosion testing, in particular to a salt spray corrosion testing box for spray-adjustable dry-wet composite testing. Background Art

[0002] In the process of evaluating the corrosion resistance of some materials, it is often necessary to use a dry-wet composite test salt spray corrosion test chamber. In order to adapt to different environmental simulations, although the common salt spray corrosion test chamber can adjust the spray size according to the actual situation, there are still some problems in actual use. For example, the dry-wet composite test is generally integrated in the salt spray corrosion test chamber, and it is impossible to realize the parallel test of multiple combined environments in one chamber. After the salt spray atomization test, the drying stage can be carried out, and finally the wetting stage is carried out, which makes the test time longer and difficult to realize continuous test work. In addition, the existing test chamber does not avoid the cross-contamination problem between the combinations of factors. The more residual salt spray solution will also affect the test results. Moreover, since the positions of the test workpieces placed inside the salt spray test equipment are scattered, and the position of the spray head is fixed, the amount of salt spray attached to the surface of the test workpiece close to the nozzle is more, and the amount of salt spray attached to the surface of the test workpiece far away from the nozzle is less, and there is a phenomenon of inconsistent deposition. Sometimes it is necessary to conduct a comparative salt spray test on multiple samples. At this time, the distance between the multiple samples on the placement rack and the salt spray nozzle is different, resulting in a difference in the uniformity of contact between each sample and the salt spray, and the variables cannot be controlled.

[0003] In view of the above problems, the present invention document proposes a salt spray corrosion test chamber for dry-wet composite testing with adjustable spray. Summary of the invention

Secondly, the transmission is transmitted between the second bevel gear 2073 and the third bevel gear 1052, so that the third bevel gear 1052 drives the third rotating shaft 2035 to rotate, so that the third bevel gear 1052 above and the fourth three-foot transmission, the first rotating shaft 1041 can drive the protrusion 1047 through the arc groove 1043 to drive the sliding sleeve 1042 to reciprocate, so that the hot air head group 1033 reciprocates, thereby further improving the uniformity of product drying, and the sliding sleeve 1042 also drives the scraper 1045 to clean the observation window of the box cover 102 to prevent water mist from affecting the observation of the product, and the scraper 1045 is V-shaped, so that the water can be diverted to the sponge 1061, thereby preventing the liquid from dripping down again and affecting the product.

[0054] Working principle: The cylinder 2014 and the disc 2011 are driven to rotate by the first motor 204, so that the partition 2012 rotates for partition control. When the product is in the salt spray area, the salt spray head 107 of the salt spray test equipment 101 sprays salt spray to make the salt spray adhere to the product, and the third rotating shaft 2035 is driven to rotate by the double-axis motor 202. Under the transmission of the first bevel gear 2033, the transmission is made between the sprocket 2032 and the chain 2031, so that the chain 2031 conveys the product through the clamping assembly 206 for circular motion, and the movement of the gear 2061 can also be transmitted with the gear rod 205. The self-rotation of the gear 2061 can drive the fourth rotating shaft 2062 to rotate, so that the rotation of the clamping sleeve 2063 drives the product to rotate, so that the product is evenly contacted with the salt spray for testing. After the test, the speed of the double-axis motor 202 is controlled by frequency conversion, and the residual liquid is smoothly thrown off the product by centrifugation. At this time, the product is transferred to the drying area. At this time, the hot air blower 1031 The hot air is delivered to the hot air head group 1033 to dry the product, and the first bevel tooth 2033 is also driven by the second bevel tooth 2073 to rotate the fifth shaft 2071, and the other second bevel tooth 2073 is driven by the third bevel tooth 1052, so that the second shaft 1051 drives the third bevel tooth 1052 and the fourth bevel tooth 1046 to drive. At this time, the first shaft 1041 drives the protrusion 1047 through the arc groove 1043 to drive the sliding sleeve 1042 to reciprocate, so that the scraper Plate 1045 drives the hot air head group 1033 to move back and forth, so that the hot air head group 1033 dries the product evenly, and the product moves on the inner wall of the box cover 102. If there are residual droplets on the box cover 102, the scraper 1045 will scrape off the droplets, and the droplets will flow along the scraper 1045 to the sponge 1061, and will be absorbed and stored by the sponge 1061. After drying, the product is transferred to the humidification area. At this time, after the humidification operation is performed by the humidification head 108, the cyclic salt spray test operation is performed again.
