Description

Technical Field

[0001] The utility model relates to the technical field of corrosion test chambers, in particular to a corrosion dust test chamber. Background Art

[0002] A corrosion test chamber is a type of experimental equipment used to simulate corrosive environments and is used to test the durability and corrosion resistance of materials, coatings, and products under corrosive conditions. Corrosion test chambers are typically used to evaluate the corrosion resistance of metals, coatings, electronic components, automotive parts, and other products in acidic, alkaline, salt spray, and humid heat environments. By simulating corrosive environments, corrosion test chambers can evaluate the corrosion resistance of metal materials or coatings under specific conditions, helping to predict the potential service life of products in corrosive environments and thus guiding design and material selection. Corrosion test chambers can be used for quality control during the product production process to ensure that products meet specified corrosion resistance standards. Corrosion test chambers can also test and compare the corrosion resistance of different coatings, platings, or surface treatment methods.

[0003] Chinese patent application number CN201721081723.4 discloses a salt spray corrosion test chamber that incorporates a dust generator and a vibrating plate to more specifically simulate various conditions in a natural environment, resulting in metal corrosion results that are more consistent with real-world conditions. However, the salt spray generator of the aforementioned salt spray corrosion test chamber is located on top of the dust generator, with no separation between the two. Dust output from the separate generator is easily lifted and enters the salt spray generator, thereby clogging the test chamber's salt spray generator, spray device, and other liquid delivery devices. Furthermore, the salt spray and salt solution cannot be recovered, resulting in waste of liquid and increased testing costs. Utility Model Content

[0029] See also Figures 1 to 4 The utility model discloses a corrosion dust test box 10, which includes a box cover 100, a box body 200, a tower spray system 300 and a dust generating system 400. The box cover 100 is arranged on the top side of the box body 200 and corresponds to the open end of the box body 200; the tower spray system 300 is arranged on one side of the box body 200, and the output end of the tower spray system 300 extends to the inside of the box body 200. The tower spray system 300 can output salt mist into the inside of the box body 200, thereby simulating a salt mist corrosion environment inside the box body 200; the dust generating system 400 is arranged at one end of the box body 200, and the output end of the dust generating system 400 can output dust into the inside of the box body 200, thereby simulating a dust environment inside the box body 200.

The salt spray test chamber 210 is arranged in the middle of the box 200, and the dust test chamber 220 is arranged on the outside of the salt spray test chamber 210. The salt spray test chamber 210 is connected to the opening at the top of the dust test chamber 220 through the top opening, so that the salt spray input into the salt spray test chamber 210 can be input into the dust test chamber 220, thereby allowing the sample placed inside the dust test chamber 220 to undergo corrosion testing and dust testing at the same time.

[0030] Furthermore, in order to prevent the dust inside the dust test chamber 220 from escaping into the salt spray test chamber 210, a dust filter 221 is provided at the opening at the top of the dust test chamber 220. Under the premise of ensuring that the salt spray can enter the interior of the dust test chamber 220, the dust is effectively prevented from entering the salt spray test chamber, thereby preventing the dust from affecting the monitoring of the salt spray by the tower spray system 300 and the recycling of the salt solution.

[0031] Furthermore, a U-shaped plate 230 is provided inside the box 200, and the U-shaped plate 230 is arranged between the salt spray test chamber 210 and the dust test chamber 220. That is, the salt spray test chamber 210 and the dust test chamber 220 are separated by the U-shaped plate 230 to ensure the relative independence of the two in the lateral direction, thereby preventing a large amount of dust from entering the salt spray test chamber 210 and affecting the normal operation of the tower spray system 300.

[0032] Furthermore, the box body 200 is provided with a waste liquid collection chamber 240, which is arranged at the bottom of the box body 200, and the waste liquid collection chamber 240 is respectively connected to the salt spray test chamber 210 and the dust test chamber 220, so that the droplets dripping from the salt spray test chamber 210 and the droplets of mixed oil and dust falling from the dust test chamber 220 can converge into the waste liquid collection chamber 240 for temporary storage and collection, and be discharged to the external waste liquid collection device through the drain port 241. Specifically, the box body 200 is provided with a leakage orifice plate 242, which is arranged at the bottom of the salt spray test chamber 210 and the dust test chamber 220, and the leakage orifice plate 242 is arranged at the top of the waste liquid collection chamber 240. That is, the salt spray test chamber 210 and the dust test chamber 220 are connected to the waste liquid collection chamber 240 through the leakage orifice plate 242, so that the waste liquid can fall into the waste liquid collection chamber 240 under the action of its own gravity to complete the waste liquid collection.

[0033] Furthermore, the housing 200 is provided with an installation cavity 250, which is disposed at one end of the housing 200. The corresponding dust generating system 400 includes a dust generator 410 and a dust blower 420. The dust generator 410 and the dust blower 420 are installed in the installation cavity 250, and the output ends of the dust generator 410 and the dust blower 420 both extend into the dust test cavity 220.

[0034] Furthermore, the box 200 is provided with a plurality of storage beams 260, and the plurality of storage beams 260 are erected on the top of the box 200, and each storage beam 260 passes through the dust test chamber 220, the salt spray test chamber 210, and the dust test chamber 220 in sequence, that is, each storage beam 260 passes through the U-shaped plate 230 from one side of the top of the box 200 to the other side of the top of the box 200 for placing the sample.

[0035] Furthermore, the tower spray system 300 is provided with a tower sprayer 310 and two collectors 320. The tower sprayer 310 and the two collectors 320 are both arranged inside the salt spray test chamber 210, and the tower sprayer 310 and the two collectors 320 are both connected to the tower spray system 300 to stably circulate and output salt mist to the inside of the box 200.

[0036] Furthermore, one side of the box cover 100 is hingedly connected to the open side of the box body 200 to facilitate opening and closing of the box cover 100 and the box body 200. Specifically, the box cover 100 is provided with a driving cylinder 110, which is mounted on a side surface of the box body 200. The output end of the driving cylinder 110 is connected to the corresponding side surface of the box cover 100, so that the box cover 100 can be automatically opened and closed relative to the box body 200 by the driving cylinder 110.

[0037] Furthermore, a water-sealing groove 270 is provided at the opening of the box body 200 corresponding to the box cover 100. The water-sealing groove 270 corresponds to the closed end surface of the box cover 100. In actual use, when an appropriate amount of water is poured into the water-sealing groove 270 and the box cover 100 is closed to the opening of the box body 200 and engages with the water-sealing groove 270, the water in the water-sealing groove 270 can effectively prevent the overflow of salt mist from the interior of the box body 200.

[0038] In summary, the corrosion dust test chamber disclosed in the present invention outputs salt mist into the interior of the chamber through a tower spray system, and outputs dust into the interior of the chamber through the output end of the dust generating system, thereby simulating a mixed environment of salt mist and dust within the chamber. Specifically, the chamber includes a salt spray test chamber and a dust test chamber. The salt spray test chamber is disposed in the middle of the chamber, and the dust test chamber is disposed outside the salt spray test chamber. The salt spray test chamber is connected to the opening at the top of the dust test chamber through a top opening. Thus, the salt mist input by the salt spray test chamber can be input into the dust test chamber, thereby allowing the specimen placed in the dust test chamber to undergo corrosion testing and dust testing simultaneously. During this process, the dust filter can effectively limit the escape of dust from the dust test chamber into the salt spray test chamber, thereby effectively preventing the dust from affecting the tower spray system.
