Description

Technical Field

[0001] The utility model relates to the technical field of salt spray test, in particular to a composite salt spray test chamber. Background Technique

[0002] The salt spray test is a test method widely used to evaluate the corrosion resistance of metal materials, coatings and weldments in marine environments. By simulating the corrosive effect of salt spray in the marine environment, the salt spray test can help us understand the durability and reliability of materials in actual applications. Next, this article will introduce the principle, test process and analysis and evaluation of test results of the salt spray test. The salt spray test is based on the principle of electrochemical corrosion. In seawater, there are a large number of dissolved salts. When these salts come into contact with the metal surface, a micro-battery will be formed on the metal surface. Under the action of the micro-battery, electrochemical reactions occur on the metal surface, resulting in the dissolution and corrosion of the metal. The salt spray test is to simulate this marine environment to accelerate the corrosion process of metal materials, so as to evaluate their corrosion resistance.

[0003] The patent publication number "CN212780428U" discloses "a composite salt spray test chamber, including a transparent test cylinder. A mesh plate is fixedly installed at the middle position of the inner cavity bottom of the transparent test cylinder. The upper left part of the transparent test cylinder is movably hinged with a top cover through a pin shaft. A connecting pipe is vertically and fixedly communicated in the middle of the top cover. Bearings are fixedly embedded in the upper and lower parts of the inner cavity of the connecting pipe. The utility model sets a rubber scraper on the side wall of the transparent test cylinder. When the servo motor works, it drives the active gear to rotate, thereby driving the driven large gear at the upper end of the infusion main pipe to mesh and rotate, thereby driving the rotation of the infusion main pipe and the inverted L-shaped support arm to drive the rubber scraper to scrape the inner wall of the transparent test cylinder to remove the fog. This method can avoid the water droplets falling on the items on the mesh plate on the one hand, and can also avoid the problems of incomplete scraping of salt spray by using a sponge in the prior art and resource waste caused by the sponge adsorbing a large amount of salt spray."

[0004] In view of the above related problems, the existing salt spray test chamber has a fixed spraying angle during the spraying process. During use, it is difficult for the salt spray to fully contact the items, which will affect the effect of the anti-corrosion test. Moreover, after the test is completed, the items cannot be removed from the inside of the test chamber. When taking the items, the salt spray from the atomizing nozzle is easy to drip on the clothes, which is likely to cause the clothes to corrode.

[0031] The present application will be further described in detail below with reference to the drawings and embodiments.

[0032] Referring to Figures 1 to 4 , the embodiments of the present application provide a composite salt spray test chamber, including a test chamber body 1. A spraying assembly 2 is fixedly installed on the top of the test chamber body 1. An oscillating assembly 3 is fixedly installed on the top of the test chamber body 1. The oscillating assembly 3 includes a gear 31 and a fixed frame 32. The gear 31 is fixedly connected to one end of the spraying assembly 2. The fixed frame 32 is fixedly installed on the top of the test chamber body 1. A motor 33 is fixedly installed on the inner side wall of the fixed frame 32. The output end of the motor 33 is fixedly connected to a reciprocating lead screw 34. A moving plate 35 is threadedly connected to the side wall of the reciprocating lead screw 34. A rack 36 is fixedly installed at the bottom of the moving plate 35. The rack 36 is meshed with the gear 31. A slide bar 37 is fixedly installed on the inner side wall of the fixed frame 32. The moving plate 35 is slidably connected to the slide bar 37.

[0033] In this embodiment, first, place the item to be tested on the top of the sliding plate 41. Then, start the water pump 22 to extract the salt spray inside the storage tank 21. Next, the water pump 22 transfers the salt spray to the atomizing nozzle 23, enabling the atomizing nozzle 23 to spray it out. Then, turn on the motor 33 to drive the reciprocating screw rod 34 to rotate, so that the reciprocating screw rod 34 can drive the moving plate 35 to slide reciprocally on the surface of the sliding rod 37, causing the gear 31 to drive the atomizing nozzle 23 to swing back and forth, making the atomizing nozzle 23 evenly spray the salt spray onto the test sample, and the test effect will also increase accordingly.

[0034] Referring to Figures 1 to 4 , in one aspect of this embodiment, the spraying assembly 2 further includes a storage tank 21 and a water pump 22. The storage tank 21 is fixedly installed on the top of the test chamber body 1, and the water pump 22 is fixedly installed at the bottom of the storage tank 21. The atomizing nozzle 23 is hinged to the top of the test chamber body 1 and extends into the interior of the test chamber body 1. The gear 31 is fixedly connected to one end of the atomizing nozzle 23.

[0035] In this embodiment, then the water pump 22 transfers the salt spray to the atomizing nozzle 23, enabling the atomizing nozzle 23 to spray it out.

[0036] Referring to Figures 1 to 4 , in one aspect of this embodiment, a material taking assembly 4 is provided on the inner side wall of the test chamber body 1. The material taking assembly 4 includes a sliding plate 41. The sliding plate 41 is slidably connected to the inner bottom wall of the test chamber body 1. A stabilizing rod 42 is fixedly installed on one side of the sliding plate 41. One end of the stabilizing rod 42 is fixedly connected to a pulling block 44.

The magnet one 46 and the magnet two 47 are magnetically connected.

[0037] In this embodiment, then rotating the baffle 45 can drive the magnet one 46 and the magnet two 47 to adsorb together. Then, pulling the pulling block 44 can drive the stabilizing rod 42 to slide inside the chute 43, enabling the sliding plate 41 to slide out of the interior of the test chamber body 1, facilitating the taking out of the item. Moreover, the salt spray dripping from the atomizing nozzle 23 during the process will not drip onto the staff's clothes, further reducing the damage of the salt spray to the clothes.

[0038] Working principle: First, place the item to be tested on the top of the slide plate 41. Then, start the water pump 22 to extract the salt mist inside the storage tank 21, and then the water pump 22 transports the salt mist to the atomizing nozzle 23 so that the atomizing nozzle 23 can spray it out. Then, start the motor 33 to drive the reciprocating lead screw 34 to rotate, so that the reciprocating lead screw 34 can drive the moving plate 35 to slide back and forth on the surface of the slide bar 37, so that the gear 31 can drive the atomizing nozzle 23 to swing back and forth.

[0039] Then, rotate the baffle plate 45 to drive the magnet one 46 and the magnet two 47 to adsorb together. Then, pull the pull block 44 to drive the stabilizing rod 42 to slide inside the chute 43, so that the slide plate 41 can slide out of the interior of the test chamber body 1.
