Description

Technical Field

[0001] This utility model relates to the field of test chambers, and more specifically, to a salt spray corrosion test chamber. Background Technology

[0002] A salt spray corrosion test chamber is a test device that artificially simulates a salt spray corrosion environment. It is used to test the salt spray corrosion resistance of materials and protective layers. Its core is to atomize salt water through a specific device to form a continuous or periodic salt spray atmosphere in a sealed chamber, so as to accelerate the evaluation of the corrosion resistance of products in marine, coastal or high salt spray industrial environments. It is widely used in quality testing in industries such as metals, coatings, and electronics.

[0003] In existing technologies, when salt spray diffuses in a salt spray corrosion test chamber, it adheres to the sealing cover. However, if the weather is cold, the temperature at the sealing cover is lower than the temperature inside the test chamber. The salt spray droplets adhering to the sealing cover will gradually evaporate and lose moisture, and the salt concentration will continuously increase. After reaching saturation, it will precipitate in the form of crystals to form salt crystals. In existing technologies, the salt spray is usually wiped clean manually after the test, which cannot be done in time during the testing process, resulting in poor cleaning effect.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0006] A salt spray corrosion test chamber includes a chamber body, a control panel fixedly installed on the side of the chamber body, a sealing cover installed on the top of the chamber body, a cleaning mechanism provided in the inner cavity of the sealing cover, a temperature sensor fixedly installed on the surface of the sealing cover, and a collection box installed on the top of the inner cavity of the chamber body. The cleaning mechanism includes a cleaning component disposed at the top of the inner cavity of the sealing cover, and a driving component and a guide rod installed at the connection between the sealing cover and the cleaning component. A reset component is disposed on the surface of the sealing cover relative to the position of the driving component.

[0007] Furthermore, the cleaning component includes a V-shaped receiving plate, a flexible scraper fixedly connected to the top of the receiving plate, and a heating plate and a cooling plate fixedly connected to the receiving plate on both sides of the flexible scraper. The height of the heating plate and the cooling plate is less than the height of the flexible scraper, and the flexible scraper and the sealing cover are in close contact.

[0008] Furthermore, a first guide groove is formed between the sealing cover, the flexible scraper and the heating plate, and a second guide groove is formed between the sealing cover, the flexible scraper and the cooling plate.

[0009] Furthermore, the driving component includes a connecting block fixedly connected to the included angle of the receiving plate, a lead screw threaded through and threaded to the side of the connecting block, the lead screw and the sealing cover being rotatably connected, a rotating disk fixedly connected to one end of the lead screw, and a rotating rod fixedly connected to the side of the rotating disk.

[0010] Furthermore, the reset component includes a fixed rod fixedly installed on the side of the sealing cover, a rotating groove opened at one end of the fixed rod, and a torsion spring disposed in the inner cavity of the rotating groove. The lead screw is rotatably connected to the inside of the rotating groove, and the two ends of the torsion spring are respectively fixedly connected to the surface of the lead screw and the inner wall of the rotating groove.

[0011] Furthermore, one end of the guide rod extends horizontally through the interior of the receiving plate, and the guide rod and the receiving plate are slidably sleeved together. Both ends of the guide rod are fixedly connected to the inner wall of the sealing cover.

[0012] Furthermore, the collection box is correspondingly arranged with the first guide channel and the second guide channel, and the collection box is arranged in a square shape.

[0013] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: (1) This solution utilizes a cleaning mechanism, which can be driven by a rotating component and guided by a guide rod to make the cleaning component move along the inner wall of the sealing cover, thereby scraping off the salt mist on the inner wall of the sealing cover. By setting a reset component, the torsion spring inside the reset component can be compressed when the cleaning component moves forward, and the cleaning component can be moved automatically in the opposite direction by the reset force of the torsion spring. This allows the salt mist on the inner wall of the sealing cover to be cleaned during the test, solving the problem of untimely salt mist cleaning in the prior art.

[0014] (2) This solution utilizes a heating plate to heat the salt mist on the inner wall of the sealing cover when the cleaning component moves forward, thereby liquefying the crystallized salt crystals. The salt crystals are then scraped off by a flexible scraper and drained through the first guide channel. When the component moves in the reverse direction, a cooling plate is used to allow the heated salt solution to re-adhere and accumulate, and then scraped off by a flexible scraper. Finally, the solution is drained through the second guide channel, thus improving the cleaning effect of salt mist on the surface of the sealing cover. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1: Please see Figure 1-5 A salt spray corrosion test chamber includes a chamber body 1, a control panel 2 fixedly installed on the side of the chamber body 1, a sealing cover 3 installed on the top of the chamber body 1, a cleaning mechanism 4 provided in the inner cavity of the sealing cover 3, a temperature sensor 5 fixedly installed on the surface of the sealing cover 3, and a collection box 6 installed on the top of the inner cavity of the chamber body 1. The cleaning mechanism 4 can scrape away salt spray from the inner wall of the sealing cover 3, the temperature sensor 5 can monitor the temperature of the surface of the sealing cover 3, and the collection box 6 can guide the scraped salt spray. The cleaning mechanism 4 includes a cleaning component 41 located at the top of the inner cavity of the sealing cover 3, a driving component 42 and a guide rod 44 installed at the connection between the sealing cover 3 and the cleaning component 41, and a reset component 43 located on the surface of the sealing cover 3 relative to the driving component 42. With the driving component 42 in place and limited by the guide rod 44, the cleaning component 41 can move along the guide rod 44 to scrape away salt spray from the inner wall of the sealing cover 3. With the reset component 43, the driving component 42 can move in the opposite direction, reducing labor intensity.

[0021] Furthermore, the cleaning component 41 includes a V-shaped receiving plate 411, a flexible scraper 412 fixedly connected to the top of the receiving plate 411, a heating plate 413 and a cooling plate 414 fixedly connected to the receiving plate 411 on both sides of the flexible scraper 412, respectively, and the height values ​​of the heating plate 413 and the cooling plate 414 are less than the height value of the flexible scraper 412, and the flexible scraper 412 and the sealing cover 3 are in close contact; a first guide groove 415 is formed between the sealing cover 3, the flexible scraper 412 and the heating plate 413, and a second guide groove 416 is formed between the sealing cover 3, the flexible scraper 412 and the cooling plate 414.

[0022] Specifically, by setting up a heating plate 413, the salt mist on the inner wall of the sealing cover 3 can be heated when the cleaning component 41 moves in the forward direction, thereby liquefying the crystallized salt crystals. After being scraped off by the flexible scraper 412, the liquid is drained through the first guide channel 415. At the same time, by setting up a temperature sensor 5, the temperature of the sealing cover 3 can be detected during the heating process. When the temperature of the sealing cover 3 reaches the threshold, the heating plate 413 is turned off to prevent the sealing cover 3 from being damaged by excessive temperature. When the cleaning component 41 moves in the reverse direction, the cooling plate 414 can be set up to allow the heated salt solution to re-adhere and accumulate, and then be scraped off by the flexible scraper 412. Finally, the liquid is drained through the second guide channel 416. This can improve the cleaning effect of salt mist on the surface of the sealing cover 3.

[0023] Furthermore, the driving component 42 includes a connecting block 421 fixedly connected to the included angle of the receiving plate 411. A lead screw 422 is threaded through and threaded onto the side of the connecting block 421. The lead screw 422 is rotatably connected to the sealing cover 3. A rotating disk 423 is fixedly connected to one end of the lead screw 422. A rotating rod 424 is fixedly connected to the side of the rotating disk 423. By rotating the rotating rod 424, the rotating disk 423 is driven to rotate, thereby causing the lead screw 422 to rotate within the connecting block 421. Under the limiting action of the guide rod 44, the cleaning component 41 can move along the inner wall of the sealing cover 3 to scrape away the smoke on its surface.

[0024] The reset component 43 includes a fixed rod 431 fixedly installed on the side of the sealing cover 3, a rotating groove 432 opened at one end of the fixed rod 431, and a torsion spring 433 disposed in the inner cavity of the rotating groove 432. The lead screw 422 is rotatably connected to the inside of the rotating groove 432, and the two ends of the torsion spring 433 are fixedly connected to the surface of the lead screw 422 and the inner wall of the rotating groove 432, respectively. When the lead screw 422 rotates in the forward direction, the torsion spring 433 in the rotating groove 432 is compressed. When the cleaning component 41 moves to the other side of the sealing cover 3, the rotating rod 424 is released. Under the action of the reset force of the torsion spring 433, the lead screw 422 can be rotated in the reverse direction, which in turn allows the cleaning component 41 to move in the reverse direction to perform secondary scraping on the inner wall of the sealing cover 3. This improves the scraping effect of salt spray and also reduces the labor intensity of the workers.

[0025] It should also be noted that one end of the guide rod 44 extends horizontally through the interior of the receiving plate 411, and the guide rod 44 and the receiving plate 411 are slidably sleeved together. Both ends of the guide rod 44 are fixedly connected to the inner wall of the sealing cover 3. By setting the guide rod 44, the cleaning component 41 can be guided and limited.

[0026] Furthermore, the collection box 6 is correspondingly arranged with the first guide channel 415 and the second guide channel 416 to facilitate the diversion of the salt spray scraped in the first guide channel 415 and the second guide channel 416. The collection box 6 is arranged in a U-shape to avoid interference with the placement of the testing machine.

[0027] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
