Description

Technical Field

[0001] This utility model belongs to the technical field of salt spray test chambers, and specifically relates to a salt spray test chamber with salt spray treatment function. Background Technology

[0002] With the acceleration of global industrialization, especially the construction of infrastructure in coastal areas, the development of marine engineering, and the widespread application of electronic equipment in complex environments, the risk of salt spray corrosion to materials and products has increased significantly. As a core piece of equipment for simulating salt spray corrosion environment and testing the corrosion resistance of materials and products, the performance of salt spray testing machines directly affects the accuracy and reliability of test results. It is of great significance for ensuring product quality, extending service life, and reducing maintenance costs. The salt spray mist generated after existing salt spray tests still has strong corrosiveness and therefore needs to be treated.

[0003] For example, Chinese patent CN219284966U discloses a salt spray test machine with salt spray treatment function, including a test machine body. A protective cover is rotatably connected to the upper end of the test machine body. A connecting pipe is installed on one end of the protective cover. A flexible hose is detachably installed on one end of the connecting pipe. An air extraction device is installed on one end of the flexible hose. A purification box is connected to one end of the air extraction device through a pipe. A heating tube is installed inside the purification box. An exhaust pipe is installed on one end of the purification box. A collection tray is slidably installed on the front surface of the purification box.

[0004] The aforementioned patent describes a method that uses an air extraction device to draw the salt spray gas from inside the protective cover after use into the purification chamber via connecting pipes and hoses. The salt spray gas is then heated, dried, and purified by a heating element, with the resulting dry air discharged through an exhaust pipe. However, relying solely on the heating element for drying and purification only evaporates the moisture in the salt spray, causing the salt to crystallize. It cannot effectively remove other acidic or alkaline gases or harmful impurities that may be present in the salt spray. Furthermore, the contact efficiency between the salt spray gas and the electric heating element is severely insufficient, and some of the salt spray gas may be directly discharged through the exhaust pipe. Therefore, improvements are needed. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a salt spray test machine with salt spray treatment function to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A salt spray testing machine with salt spray treatment function includes a salt spray testing machine body. A protective cover is hinged to one side of the salt spray testing machine body. A connecting pipe is fixedly connected to one side of the protective cover. A flexible hose is fixedly connected to one side of the connecting pipe. An air extraction device is fixedly connected to the middle of the flexible hose. A purification chamber is fixedly connected to the side of the flexible hose away from the connecting pipe.

A second guide plate is fixedly connected to the top of the support plate. Electric heating tubes are fixedly connected inside both the first and second guide plates. A filter box is provided on the side of the purification chamber away from the flexible hose. A gas sensor is provided on one side of the filter box. An activated carbon filter layer is slidably connected to the side of the filter box near the purification chamber. An alkaline neutralizing filter layer is slidably connected to the side of the filter box located on the activated carbon filter layer. A fixing frame is fixedly connected to the side of the filter box near the activated carbon filter layer and the alkaline neutralizing filter layer. A disassembly component is provided on one side of the fixing frame.

[0008] As a preferred technical solution, the first guide plate and the second guide plate are alternately arranged, and the first guide plate and the second guide plate are inclined.

[0009] As a preferred technical solution, a gas guide pipe is fixedly connected between the purification box and the filter box, an exhaust pipe is fixedly connected to the side of the filter box away from the gas guide pipe, and the gas sensor is fixedly connected to the exhaust pipe.

[0010] As a preferred technical solution, the disassembly assembly includes a slider, which is slidably connected inside the fixed frame. A positioning rod is fixedly connected to one side of the slider. A handle is fixedly connected to one side of the activated carbon filter layer and the alkaline neutralization filter layer.

[0011] As a preferred technical solution, limit grooves are provided on both sides of the inside of the fixed frame, and limit blocks are slidably connected inside the limit grooves. One side of the limit block is fixedly connected to one side of the slider.

[0012] In summary, the present invention has the following main advantages:

[0013] First, this utility model, by installing a first guide plate and a second guide plate in the purification box connected to the main body of the salt spray test machine, the two are alternately and inclined, and electric heating tubes are installed in both the first guide plate and the second guide plate. The first guide plate and the second guide plate extend the contact path and time with the electric heating tubes, which can prevent some salt spray gas from escaping directly, so that the salt spray gas can contact the heating tubes more fully, ensure that the moisture evaporates fully, and improve the salt spray purification efficiency.

[0014] Secondly, this utility model connects a filter box to one side of the purification chamber. The filter box contains an activated carbon filter layer and an alkaline neutralization filter layer. The activated carbon adsorption layer is used to adsorb harmful gases and organic impurities, and the alkaline neutralization filter layer can neutralize acidic gases, further improving the purification effect, reducing pollution to the surrounding environment, and ensuring that the exhaust air meets stricter environmental protection standards. A gas sensor is also installed to detect the gas composition before and after passing through the activated carbon adsorption layer and the alkaline neutralization filter layer in real time. If the concentration of harmful gases or acidic gases that should have been adsorbed or neutralized in the treated gas exceeds the set standard value, it indicates that the activated carbon adsorption layer or the alkaline neutralization filter layer has failed and needs to be replaced. Both can be replaced by disassembling the components. Attached Figure Description

[0021] Example

[0022] refer to Figures 1 to 5 This embodiment describes a salt spray testing machine with salt spray treatment function, comprising a salt spray testing machine body 1. The structure of the salt spray testing machine body 1 is referenced in application number CN202320167968.8, which is a mature existing technology product; its specific structural principle is not detailed here. A protective cover 2 is hinged to one side of the salt spray testing machine body 1. A connecting pipe 4 is fixedly connected to one side of the protective cover 2. A flexible hose 3 is fixedly connected to one side of the connecting pipe 4. An air extraction device 5 is fixedly connected to the middle of the flexible hose 3. A purification chamber 6 is fixedly connected to the side of the flexible hose 3 away from the connecting pipe 4. A support plate 7 is fixedly connected to one side of the interior of the purification chamber 6. A first guide plate 8 is fixedly connected to the inner wall of the top of the purification chamber 6, and multiple first guide plates 8 are provided. A second guide plate 9 is fixedly connected to the top of the support plate 7. Electric heating tubes 10 are fixedly connected inside both the first guide plate 8 and the second guide plate 9. A filter box 11 is provided on the side of the purification box 6 away from the hose 3. A gas sensor 151 is provided on one side of the filter box 11. An activated carbon filter layer 13 is slidably connected inside the filter box 11 on the side close to the purification box 6. An alkaline neutralization filter layer 14 is slidably connected inside the filter box 11 on the side of the activated carbon filter layer 13. A fixing frame 17 is fixedly connected on the side of the filter box 11 close to the activated carbon filter layer 13 and the alkaline neutralization filter layer 14. A disassembly component 16 is provided on one side of the fixing frame 17. After the salt spray test is performed on the main body 1 of the salt spray tester, the exhaust device 5 is turned on, and the salt spray gas in the protective cover 2 is drawn into the purification box 6 through the connecting pipe 4 and the hose 3.

[0023] refer to Figure 2 The first guide plate 8 and the second guide plate 9 are alternately arranged, and the first guide plate 8 and the second guide plate 9 are inclined. After the salt spray gas enters the purification box 6, under the action of the alternately inclined first guide plate 8 and the second guide plate 9, the gas is ensured to fully contact the electric heating tube 10 inside the plate to evaporate the moisture.

[0024] refer to Figure 2-3 A gas duct 12 is fixedly connected between the purification chamber 6 and the filter box 11. An exhaust pipe 15 is fixedly connected to the side of the filter box 11 away from the gas duct 12. The gas sensor 151 is fixedly connected to the exhaust pipe 15. By setting the gas duct 12, the salt spray gas, which has been preliminarily purified by the first guide plate 8 and the second guide plate 9, enters the filter box 11 from the purification chamber 6 through the gas duct 12. The purified gas is discharged through the exhaust pipe 15. The gas sensor 151 detects the gas composition in the exhaust pipe 15 in real time to monitor the purification effect.

[0025] refer to Figure 3-4The disassembly assembly 16 includes a slider 164, which is slidably connected inside the fixed frame 17. A positioning rod 163 is fixedly connected to one side of the slider 164. A handle 161 is fixedly connected to one side of the activated carbon filter layer 13 and the alkaline neutralization filter layer 14. A positioning hole 162 is provided inside the handle 161. One side of the positioning rod 163 is movably connected to the positioning hole 162. A screw 165 is rotatably connected inside the fixed frame 17. The slider 164 is threadedly connected to the screw 165. A torsion wheel 166 is fixedly connected to the side of the screw 165 extending out of the fixed frame 17. The torsion wheel 166 is rotatably connected to the fixed frame 17. 7. By setting up the disassembly component 16, when the activated carbon filter layer 13 and the alkaline neutralization filter layer 14 reach saturation and need to be replaced, the torsion wheel 166 is rotated. The torsion wheel 166 drives the screw 165 to rotate. The slider 164, which is threadedly connected to the screw 165, slides along the fixed frame 17 under the restriction of the limiting groove 18 and the limiting block 19, so that the positioning rod 163 is pulled out from the positioning hole 162 of the handle 161. Then, the activated carbon filter layer 13 and the alkaline neutralization filter layer 14 are pulled out from the filter box 11 through the handle 161. After replacing the new filter layer, the operation is reversed to fix the new filter layer. Therefore, the activated carbon filter layer 13 and the alkaline neutralization filter layer 14 can be replaced conveniently without complicated tools.

[0026] refer to Figure 4 The fixed frame 17 has limit grooves 18 on both sides inside. Limit blocks 19 are slidably connected inside the limit grooves 18. One side of the limit block 19 is fixedly connected to one side of the slider 164. By setting the limit grooves 18 and the limit blocks 19, the slider 164 is ensured to slide smoothly, so that the positioning rod 163 can be accurately inserted into or pulled out of the positioning hole 162 of the handle 161.

[0027] Operating Principle and Advantages: After the salt spray test chamber body 1 is completed, the suction device 5 in the middle of the hose 3 is activated. Since the protective cover 2 is hinged to one side of the salt spray test chamber body 1, a relatively closed space is formed. Under the suction of the suction device 5, the residual salt spray gas in the protective cover 2 is sequentially drawn into the purification chamber 6 through the connecting pipe 4 and the hose 3, completing the initial collection of salt spray gas. After the salt spray gas enters the purification chamber 6, electric heating tubes 10 are installed in both the first guide plate 8 and the second guide plate 9. The first guide plate 8 and the second guide plate 9 extend the contact path and time with the electric heating tubes 10, which can prevent some salt spray gas from escaping directly, allowing the salt spray gas to contact the heating tubes more fully and ensuring that the moisture evaporates fully. In the filter box 11, the gas first passes through the activated carbon filter layer 13 near the side of the purification chamber 6. Utilizing the adsorption characteristics of activated carbon, residual harmful gases and organic impurities in the gas are removed. Then, it passes through the activated carbon filter layer 13 located on one side of the activated carbon filter layer 13. The alkaline neutralization filter layer 14 neutralizes any acidic components that may be present in the gas. The gas, after deep purification, is discharged through the exhaust pipe 15, which is fixedly connected to the side of the filter box 11 away from the gas guide pipe 12. The gas sensor 151 on the exhaust pipe 15 monitors the composition of the discharged gas in real time. Once the concentration of harmful substances in the gas exceeds the set standard, a feedback signal is sent in a timely manner so that the equipment operating status or the condition of the filter layer can be replaced. When the activated carbon filter layer 13 and the alkaline neutralization filter layer 14 reach saturation due to adsorption or neutralization and need to be replaced, the torsion wheel 166 is rotated. The torsion wheel 166 drives the screw 165 to rotate. The slider 164, which is threaded to the screw 165, slides along the fixed frame 17 under the restriction of the limiting groove 18 and the limiting block 19, so that the positioning rod 163 is pulled out from the positioning hole 162 of the handle 161. Then, the activated carbon filter layer 13 and the alkaline neutralization filter layer 14 are pulled out from the filter box 11 through the handle 161 to replace the new filter layer.
