Description

Technical Field

[0001] This application relates to the technical field of salt spray test, and particularly to a monitoring mechanism for the sedimentation liquid of salt spray test and a salt spray test device. Background Art

[0002] When verifying the long-term stable use of products, the salt spray in the atmosphere is a destructive factor that cannot be ignored. In order to determine the effectiveness of the protective layer and decorative layer of product materials, and to measure the impact of salt deposits on the physical and electrical properties of products, it is usually necessary to conduct a salt spray test on the products.

[0003] The salt spray test is a laboratory environmental test method that simulates the atmospheric salt spray environment. During the test, the product to be tested is placed in the test chamber, and then a salt solution with a preset pH value is sprayed in the form of droplets through a spray tower arranged in the test chamber and acts on the products in the test chamber. During the test, the atomized salt solution will form a sedimentation liquid after sedimentation. The pH value and concentration of the sedimentation liquid are one of the key parameters for evaluating the salt spray test and have a great impact on the test results. The narrower the change range of the pH value and concentration of the sedimentation liquid is controlled, the better the reproducibility of the test results and the higher the credibility. Therefore, it is necessary to detect the pH value and concentration of the sedimentation liquid during the test.

[0004] At present, the detection methods for the pH value and concentration of the sedimentation liquid are as follows: A measuring cylinder is set in the test chamber, and the measuring cylinder collects the salt solution sprayed from the spray tower. The test operator regularly detects the pH value and concentration of the collected sedimentation liquid to obtain the pH value and concentration results. However, such a test method requires opening the box regularly during the salt spray test, taking out the measuring cylinder, and then detecting the pH value and concentration of the sedimentation liquid. If the pH value and concentration of the sedimentation liquid do not meet the requirements of the test standard in the first cycle or a certain cycle, then according to the standard regulations, the tests that have been carried out will be judged as invalid and need to start the test again. Therefore, this method has low efficiency, the test time cannot be controlled, and there are also large detection errors, which affect the test accuracy. As the number of detections increases, the cumulative error also becomes larger and larger. In addition, the salt solution in the salt spray test is irritating to the human skin, respiratory tract, etc. Regularly taking out the measuring cylinder from the salt spray test environment to detect the pH value and concentration of the sedimentation liquid will inevitably cause certain irritation to the human skin and respiratory tract, which is not conducive to the health of the test personnel. Moreover, this measurement method requires manual recording of data, which is rather inconvenient and not conducive to improving the efficiency of the salt spray test. Summary of the Utility Model

[0042] An embodiment of this application provides a salt spray test sedimentation liquid monitoring mechanism for online real-time monitoring of the pH value and concentration of the sedimentation liquid in a salt spray test. Among them, the sedimentation liquid refers to the solution formed after the atomized salt solution in the salt spray test settles. Specifically, refer to Figure 1 and Figure 2 , the salt spray test sedimentation liquid monitoring mechanism of an embodiment includes a collection component 10, a graduated cylinder 20, a pH value detector 31, and a concentration detector 32. Among them, the collection component 10 is used to be arranged inside the salt spray test chamber 50 and is used to collect the sedimentation liquid. The graduated cylinder 20 is connected to the collection component 10. The graduated cylinder 20 is used to be arranged on the outer wall of the salt spray test chamber 50 and is used to store the sedimentation liquid collected by the collection component 10. The probe 311 of the pH value detector 31 is arranged in the graduated cylinder 20 to detect the pH value of the sedimentation liquid in the graduated cylinder 20 in real time. The probe 321 of the concentration detector 32 is arranged in the graduated cylinder 20 to detect the concentration of the sedimentation liquid in the graduated cylinder 20 in real time.

[0043] In the above salt spray test sediment monitoring mechanism, by arranging a collection assembly 10 inside the salt spray test chamber 50, the deposited liquid formed after the atomized salt solution settles can be collected, and the deposited liquid is introduced into a graduated cylinder 20 located on the outer wall of the salt spray test chamber 50. Then, the pH value of the deposited liquid in the graduated cylinder 20 is detected by a pH meter 31, and the concentration of the deposited liquid in the graduated cylinder 20 is detected in real time by a concentration detector 32, so as to realize the on-line real-time monitoring of the pH value and concentration of the sediment in the salt spray test, thereby ensuring the accuracy of the salt spray test results. Compared with the traditional monitoring method that requires regular shutdown, frequently opening the salt spray test chamber 50 to place and remove the graduated cylinder 20, and manually detecting and recording the pH value and concentration of the sediment, the salt spray test sediment monitoring mechanism of the present application can on-line real-time monitor the pH value and concentration of the sediment in the salt spray test without shutdown, ensuring the stable progress of the salt spray test. At the same time, the collection assembly 10 is used to introduce the deposited liquid into the graduated cylinder 20 located outside the salt spray test chamber 50, so that it is not necessary to frequently open the salt spray test chamber 50 to place and remove the graduated cylinder 20, improving the test efficiency and avoiding the harm of the salt spray environment in the salt spray test chamber 50 to the skin and respiratory tract of the test personnel. In addition, the pH value of the deposited liquid is automatically detected by the pH meter 31, and the concentration of the deposited liquid is automatically detected by the concentration detector 32, which can improve the detection accuracy while improving the detection efficiency, and further ensure the efficiency and accuracy of the salt spray test.

[0044] See Figure 1 , Optionally, in an embodiment, the salt spray test sediment monitoring mechanism further includes a temperature control assembly 40, the temperature control assembly 40 is in heat transfer connection with the graduated cylinder 20, and the temperature control assembly 40 is used to maintain the deposited liquid in the graduated cylinder 20 within a preset temperature range. In this way, it is ensured that the pH value detection and concentration detection of the sediment are carried out at a specified temperature, avoiding the problem in the traditional method that after the graduated cylinder 20 is taken out, the temperature of the salt solution cannot be guaranteed to be within the specified temperature range, resulting in a large detection error, affecting the test accuracy, and with the increase of the detection times, the cumulative error is also getting larger and larger, thereby further ensuring the accuracy of the salt spray test.

[0045] Specifically, in one embodiment, the temperature control component 40 includes a temperature sensor (not shown), a heater (not shown), and a cooler (not shown). The temperature sensor is disposed in the graduated cylinder 20 and is used to obtain the temperature value of the deposition liquid in the graduated cylinder 20. The heater is in contact with the outer wall of the graduated cylinder 20 and is electrically connected to the temperature sensor. The heater can heat the graduated cylinder 20 when the temperature value obtained by the temperature sensor is lower than the preset temperature range, thereby increasing the temperature of the deposition liquid. Exemplarily, the heater is a resistance heater and is in contact with the bottom of the outer wall of the graduated cylinder 20. The cooler is in contact with the outer wall of the graduated cylinder 20 and is electrically connected to the temperature sensor. The cooler can cool the graduated cylinder 20 when the temperature value obtained by the temperature sensor is higher than the preset temperature range, thereby reducing the temperature of the deposition liquid. Exemplarily, the cooler can be a thermoelectric cooler and is in contact with the bottom of the outer wall of the graduated cylinder 20. Thus, by the cooperation of the temperature sensor, the heater, and the cooler, the sedimentation liquid in the graduated cylinder 20 can be stably controlled within the preset temperature range, improving the detection accuracy.

[0046] See Figure 1 , optionally, the collection component 10 of one embodiment includes a funnel 11 and a connecting pipe 12. The funnel 11 is disposed inside the salt spray test chamber 50. One end of the connecting pipe 12 is connected to the funnel 11, and the other end is connected to the graduated cylinder 20. And the end of the connecting pipe 12 connected to the funnel 11 is higher than the end of the connecting pipe 12 connected to the graduated cylinder 20. Thus, the deposition liquid formed after the atomized salt solution is collected by the funnel 11 and converges into the connecting pipe 12, and then the deposition liquid converges into the graduated cylinder 20 along the connecting pipe 12, realizing the collection of the deposition liquid without opening the salt spray test chamber 50, improving the continuity and efficiency of the salt spray test.

[0047] Optionally, in one embodiment, the connecting pipe 12 is a flexible pipe. By configuring the connecting pipe 12 as a flexible pipe, the connecting pipe 12 can be bent arbitrarily, thereby adapting to different application sites. Further, one end of the connecting pipe 12 is hermetically connected to the funnel 11, and the other end is hermetically connected to the graduated cylinder 20. Exemplarily, one end of the connecting pipe 12 is in interference fit with the bottom end of the funnel 11, and the other end of the connecting pipe 12 is in interference fit with the through hole on the graduated cylinder 20, so as to improve the sealing effect and avoid leakage of the deposition liquid.

[0048] See Figure 1 , in one embodiment, the salt spray test sedimentation liquid monitoring mechanism further includes a support frame 60. The support frame 60 is used to be erected inside the salt spray test chamber 50, and the funnel 11 is disposed on the support frame 60. Thus, the funnel 11 can be suspended inside the salt spray test chamber 50, raising the height of the funnel 11 to ensure that the deposition liquid collected by the funnel 11 can flow from high to low into the graduated cylinder 20.

[0049] See Figure 2, the graduated cylinder 20 includes a cylinder body 21 and a sealing cover 22. The cylinder body 21 is provided with a cavity with one end open. The probe 311 of the pH meter 31 and the probe 321 of the concentration meter are both arranged in the cavity. The sealing cover 22 is detachably connected to the open end of the cylinder body 21 and is used to seal the opening. The sealing cover 22 is provided with a pipe-passing hole, and one end of the connecting pipe 12 passes through the pipe-passing hole and into the cavity. In this way, the sediment liquid in the graduated cylinder 20 can be regularly cleaned through the opening of the cylinder body 21 and the graduated cylinder 20 can be cleaned, ensuring the detection accuracy.

[0050] Furthermore, the probe 311 of the pH meter 31 and the probe 321 of the concentration meter are both detachably arranged at the bottom of the cavity. The sealing cover 22 is also provided with a wire-passing hole, and the cables of the pH meter 31 and the concentration meter 32 pass out of the cavity through the wire-passing hole. In this way, by removing the sealing cover 22 of the graduated cylinder 20, the probe 311 of the pH meter 31 and the probe 321 of the concentration meter can be detached, which is convenient for cleaning and calibration.

[0051] Optionally, in one embodiment, the graduated cylinder 20 is provided with scale lines, and the scale is used to indicate the liquid level height of the sediment liquid. Specifically, the graduated cylinder 20 is made of a transparent material, so that the volume of the sediment liquid in the graduated cylinder 20 can be determined by observing the position of the liquid level of the sediment liquid on the scale line. Furthermore, the amount of salt spray sedimented per unit area per unit time in the salt spray test can be monitored.

[0052] On the other hand, the present application also provides a salt spray test device. Specifically, a salt spray test chamber 50 in one embodiment. A spray tower is arranged in the salt spray test chamber 50, and the spray tower is used to spray the salt solution in the form of droplets and the salt spray test sediment liquid monitoring mechanism of any of the above embodiments. Among them, the collection assembly 10 of the fog test sediment liquid monitoring mechanism is arranged below the spray tower. In this way, the collection assembly 10 can receive the sediment liquid formed after the atomized salt solution settles, and introduce the sediment liquid into the graduated cylinder 20 located on the outer wall of the salt spray test chamber 50. Then, the pH value of the sediment liquid in the graduated cylinder 20 is detected by the pH meter 31, and the concentration of the sediment liquid in the graduated cylinder 20 is detected in real time by the concentration meter 32, so as to realize the on-line real-time monitoring of the pH value and concentration of the sediment liquid in the salt spray test.

[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0054] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
