Description

Technical Field

[0001] This utility model relates to the field of acid mist corrosion testing technology, and more specifically, to an acid mist corrosion testing device. Background Technology

[0002] Acid mist corrosion testing is an important method for evaluating the corrosion resistance of materials in acidic environments. This test simulates acid mist corrosion conditions in natural environments by exposing samples to cycles of acidic salt spray, drying, and humidification to test their corrosion resistance. The test time can range from a few hours to thousands of hours depending on the product and requirements. Evaluation indicators include salt spray time, chemical composition analysis, surface observation, electrochemical performance testing, and mechanical performance testing. Through acid mist corrosion testing, the durability and corrosion resistance of materials in complex corrosive environments can be effectively evaluated, providing important references for product design and quality control.

[0003] For example, Chinese patent disclosure: A salt spray corrosion test chamber with easily adjustable mist output, application number: CN202022338461.3, includes a test chamber body. From top to bottom, a transport pipe and a treatment chamber are fixed to the left end of the test chamber body. A fan is fixed to the transport pipe. The transport pipe passes through the upper end of the treatment chamber and extends into the alkaline solution injected inside the treatment chamber. An injection pipe and a drain pipe are fixed to the upper and lower ends of the treatment chamber, respectively. An exhaust pipe is fixed to the left end of the treatment chamber, and an activated carbon filter is fixed to the inner wall of the exhaust pipe. A test cover is fixed to the upper end of the test chamber body, and an observation window is provided on the test cover. A wiping assembly is fixed to the inner wall of the test cover. The fan can draw acidic waste gas from the test chamber into the treatment chamber through the transport pipe, where it undergoes a neutralization reaction with the alkaline solution. The gas is then further purified by passing through the activated carbon filter, facilitating waste gas treatment. The observation window can then be wiped with the wiping assembly for easy observation.

[0004] However, in the above-mentioned technical solutions, considering the physical property that acid mist is highly soluble in water, in order to ensure the stability and accuracy of the test environment, a water seal method is usually adopted to tightly seal the test container. When implementing the water seal, one of the key steps is to accurately inject an appropriate amount of water into the specially designed water seal tank. If too little water is injected, a complete and effective water seal layer may not be formed, leading to acid mist leakage or infiltration of outside air, which in turn affects the reliability of the test data. Conversely, if too much water is injected, it may cause unnecessary pressure changes inside the test container due to the gravity or flow characteristics of the water, and may even cause the water seal to fail, which also has an adverse effect on the test results. Therefore, experienced personnel are required, which increases labor costs. Utility Model Content

[0005] The main objective of this invention is to provide an acid mist corrosion testing device that effectively addresses the problem in the background art where, considering the highly soluble nature of acid mist in water, a water-sealing method is typically used to tightly seal the test container to ensure the stability and accuracy of the test environment. A key step in implementing this water-sealing is precisely injecting an appropriate amount of water into a specially designed water-sealing tank. If too little water is injected, a complete and effective water seal layer may not form, leading to acid mist leakage or infiltration of outside air, thus affecting the reliability of the test data. Conversely, if too much water is injected, the gravity or flow characteristics of the water may cause unnecessary pressure changes inside the test container, potentially even causing the water seal to fail, also negatively impacting the test results. Therefore, this method requires experienced personnel, increasing labor costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An acid mist corrosion testing device includes a main body, a water seal groove on the main body, a cover inside the water seal groove, a water inlet groove on one side of the water seal groove, a plurality of support columns on one side of the main body, a water inlet funnel on the support columns, a limit component on the water inlet funnel, and a handle on the cover.

[0008] Preferably, the water inlet funnel is located directly above the water inlet tank of the main body of the device.

[0009] Preferably, the limited-quantity component includes a component base, on which a water inlet channel is provided, and on the side of the water inlet channel near the water outlet channel is a water outlet channel.

[0010] Preferably, the component base is provided with a plurality of guide grooves on the side near the water inlet tank, a guide slide column is slidably arranged in the guide groove, a float is fixedly arranged on the guide slide column, and a baffle is fixedly arranged on the side of the float near the water outlet tank.

[0011] Preferably, the outlet trough is frustum-shaped, and the float plate is located in the inlet trough.

[0012] Preferably, the side of the baffle away from the float is frustum-shaped.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When the cover needs to be water-sealed, water is first introduced into the inlet funnel. The water in the inlet funnel is moved to the outlet trough through the water delivery trough. The outlet trough allows water to enter the water seal trough through the inlet trough to water-seal the cover. As the water volume in the water seal trough and the inlet trough gradually increases, the position of the float plate rises with the rise of the water level. The float plate drives the baffle to move, thereby gradually sealing the outlet trough through the baffle. When the water level in the water seal trough reaches the designated position, the float plate also completely seals the outlet trough through the baffle, preventing the water level in the water seal trough from being too low or too high. It can automatically bring the water level in the water seal trough to the designated position, making it convenient for staff to perform water sealing and reducing labor costs.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 As shown, an acid mist corrosion testing device includes a main body 1, a water seal trough 2 on the main body 1, a cover 3 inside the water seal trough 2, a water inlet trough 4 on one side of the water seal trough 2, several support columns 5 on one side of the main body 1, a water inlet funnel 6 on the support columns 5, a limit component 7 on the water inlet funnel 6, and a handle 8 on the cover 3.

[0020] like Figure 2 As shown, in another embodiment of the present invention, the limited component 7 includes a component base 701, a water supply trough 702 is provided on the component base 701, and a water outlet trough 703 is provided on the side of the water supply trough 702 near the water inlet trough 4.

[0021] The component base 701 is provided with a plurality of guide grooves 704 on the side near the water inlet trough 4. A guide slide post 705 is slidably arranged in the guide groove 704. A float plate 706 is fixedly arranged on the guide slide post 705. A baffle post 707 is fixedly arranged on the side of the float plate 706 near the water outlet trough 703.

[0022] When water needs to be injected into the water seal tank 2, the water in the inlet funnel 6 is first moved to the outlet tank 703 through the water delivery channel 702. The outlet tank 703 then allows water to enter the water seal tank 2 through the inlet channel 4. As the water volume in the water seal tank 2 and the inlet channel 4 gradually increases, the water level in the water seal tank 2 and the inlet channel 4 will gradually rise. At the same time, the position of the float 706 also rises with the rise in water level. The float 706 drives the baffle 707 to move, thereby gradually sealing the outlet tank 703 through the baffle 707. When the water level in the water seal tank 2 reaches the designated position, the float 706 also completely seals the outlet tank 703 through the baffle 707 to prevent the water level in the water seal tank 2 from being too low or too high.

[0023] The working principle of this acid mist corrosion testing device:

[0024] In use, when a water seal is required on the cover 3, water is first introduced into the inlet funnel 6. The water in the inlet funnel 6 moves to the outlet trough 703 through the water delivery channel 702. The outlet trough 703 then allows water to enter the water seal trough 2 through the inlet channel 4, thus sealing the cover 3 with water. As the water volume in the water seal trough 2 and the inlet channel 4 gradually increases, the water level in the water seal trough 2 and the inlet channel 4 will gradually rise. At the same time, the position of the float 706 also rises with the rise in water level. The float 706 drives the baffle 707 to move, thereby gradually sealing the outlet trough 703 through the baffle 707. When the water level in the water seal trough 2 reaches the designated position, the float 706 also completely seals the outlet trough 703 through the baffle 707, preventing the water level in the water seal trough 2 from being too low or too high. It can automatically bring the water level in the water seal trough 2 to the designated position, making it convenient for staff to perform water sealing.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
