Description

Technical Field

[0001] This application relates to the technical field of electrode maintenance, and in particular to an integrated intelligent maintenance storage tank for conductivity electrodes. Background Technology

[0002] pH electrodes and conductivity electrodes are commonly used sensors for detecting the physicochemical properties of liquids, and are widely used in environmental monitoring, water quality analysis, chemical production, biopharmaceuticals, and laboratory research.

[0003] pH electrodes are used to determine the acidity or alkalinity (pH value) of a solution, and their sensitive membranes need to be kept moist and active under specific conditions. Conductivity electrodes are used to measure the conductivity of a solution and are commonly used to assess parameters such as water purity, concentration, and ionic strength. Both are precision measuring elements, and improper storage after use can easily lead to performance degradation or even permanent damage.

[0004] Currently, routine maintenance of electrodes often involves storing them in separate bottles. pH electrodes need to be immersed in potassium chloride (KCl) buffer solution to maintain the hydration of the sensitive membrane and prevent it from drying out and failing. The conductivity electrode should be placed in a humid environment (such as a damp cotton ball containing distilled water or a special moisturizing sleeve) to avoid surface contamination and electrolyte crystallization. However, the traditional method of storing bottles separately has the following obvious drawbacks: Easily confused and misplaced: The two storage containers look similar. When operators are tired or busy, they may mistakenly insert the pH electrode into the moisture-retaining container of the conductivity electrode, or mistakenly immerse the conductivity electrode in the KCl solution, which may lead to electrode damage and inaccurate measurement. Easy to dry out and fail: Ordinary storage tanks have poor sealing, KCl solution is easy to evaporate and decrease, and the moisturizing medium is also easy to dry out. If it is not replenished in time, it will cause the electrode sensitive membrane to crack or the surface to become contaminated, causing irreversible damage. Susceptible to contamination: Open or simply covered storage methods cannot effectively prevent the intrusion of dust, foreign objects and other chemical reagents, which will contaminate the maintenance solution or electrode surface, affecting the electrode response characteristics and service life.

[0005] Therefore, there is an urgent need for an intelligent maintenance storage tank that integrates conductivity electrodes to solve the above problems. Utility Model Content

[0006] To address the issues of easy confusion, easy drying, and easy contamination, this application provides an intelligent maintenance storage tank with integrated conductivity electrodes.

[0007] This application provides an integrated intelligent maintenance storage tank for conductivity electrodes, which adopts the following technical solution: it includes a conductivity electrode storage tank, a conductivity electrode probe, a pH electrode storage tank, and a pH electrode probe. The upper outer surface of the conductivity electrode storage tank and the pH electrode storage tank are fixedly connected with an annular magnet. The inner wall of each annular magnet is fixedly connected with an annular fixing block. The upper surface of each annular fixing block is fixedly connected with a sealing gasket.

[0008] Optionally, the inner wall of the annular fixing block is provided with internal threads, and the outer surface of the positioning ring is provided with external threads. The positioning ring and the annular fixing block are detachably connected by threads, and the outer diameter of the positioning ring is adapted to the inner diameter of the annular fixing block to ensure the sealing performance after connection.

[0009] Optionally, the large-diameter end of the conical sealing cylinder is fixedly connected to the inner wall of the storage tank, and the small-diameter end faces the opening of the storage tank. The circular sealing sleeve is embedded in the inner side of the small-diameter end of the conical sealing cylinder, and the diameter of its central hole is smaller than the outer diameter of the corresponding electrode probe. The elastic deformation of the rubber material is used to achieve interference sealing after the probe is inserted.

[0010] Optionally, the detection end of the humidity sensor faces the internal cavity of the conductivity electrode storage tank, and the output end can be connected to an external alarm module such as an indicator light or a buzzer. When the humidity inside the cavity is detected to be lower than a preset threshold, an alarm is triggered to remind staff to replenish moisture.

[0011] Optionally, the detection end of the liquid level sensor extends to the bottom area of ​​the pH electrode storage tank to detect the liquid level of the KCL solution in the tank. Its output end is electrically connected to the alarm module. When the liquid level is lower than a preset value, an alarm is activated to prompt the replenishment of KCL solution.

[0012] Optionally, the first and second annular magnets are arranged with opposite poles facing each other, and their outer and inner diameters are the same. This ensures that when the probe is close to the opening of the storage tank, only the correctly matched magnet group generates an attractive force, while the incorrectly matched group generates a repulsive force, thus achieving rapid error-proof identification.

[0013] In summary, this application includes the following beneficial technical effects: 1. This utility model achieves precise matching by setting up anti-confusion: through the magnetic attraction and repulsion characteristics of ring magnet one and ring magnet two, the pH electrode probe and the conductivity electrode probe are accurately matched, completely avoiding the problem of incorrect insertion and damage caused by similar containers, and the operation is intuitive and efficient.

[0014] 2. This utility model prevents contamination by setting up multiple seals: after the positioning ring is threadedly connected to the annular fixing block, the pressure plate tightly fits the sealing gasket to form a primary seal; the conical sealing cylinder and the elastic circular sealing sleeve wrap around the outer wall of the probe to form a secondary seal. The dual structure effectively blocks dust, impurities and external solutions from intruding, avoiding contamination of the electrode surface and maintenance medium.

[0015] 3. This utility model prevents drying by setting up intelligent monitoring: the humidity sensor in the conductivity electrode storage tank monitors the humidity in the chamber in real time to ensure that the electrode is kept moist; the liquid level sensor in the pH electrode storage tank monitors the liquid level of KCL solution. Both of them promptly remind you to add water and liquid through the alarm module to prevent electrode failure caused by the medium drying out.

[0016] 4. This utility model features an integrated design for convenient use: the two storage tanks are integrated into one unit by a fixing block and a support frame, resulting in a compact structure and saving placement space; the threaded positioning ring facilitates probe disassembly and assembly, and the rubber sealing components also provide cushioning protection to prevent probe damage from impacts.

[0017] 5. This utility model has a stable and durable structure: each component is fixedly connected or threaded, the assembly is firm, and the sealing parts are made of high-elasticity rubber with strong corrosion resistance, which is suitable for long-term use in laboratory and industrial environments.

[0020] The following is in conjunction with the appendix Figure 1 The figures below provide a further detailed description of this application. The technical solutions in the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0021] This application discloses an integrated intelligent maintenance storage tank with conductive electrodes. For example... Figure 1-3 As shown, the conductivity electrode storage tank 1 and the pH electrode storage tank 2 are rigidly connected by a fixing block 15, and the support frame 16 provides stable support for the overall structure, making it easy to place on the workbench.

[0022] Probe identification and matching: Hold the conductivity electrode probe 13 or pH electrode probe 14 and place the annular magnet 10 on its top close to the annular magnet 3 on the top of any storage tank; if it is a correct match, the conductivity probe corresponds to storage tank 1 and the pH probe corresponds to storage tank 2, and the magnet group generates an attractive force, indicating that it can be inserted; if it is an incorrect match, a repulsive force is generated, preventing insertion, thus achieving anti-confusion identification.

[0023] Probe installation and sealing: Align the matched probe with the opening of the storage tank and pass it through the center hole of the circular sealing sleeve 7. The rubber hole expands elastically to adapt to the outer diameter of the probe. Rotate the probe to drive the positioning ring 12 to screw down along the internal thread of the annular fixing block 4 until the pressure plate 11 and the sealing gasket 5 are tightly fitted, completing the first-level seal. At the same time, the conical sealing cylinder 6 and the circular sealing sleeve 7 wrap around the outer wall of the probe to form a second-level seal, blocking the flow of external dust and air.

[0024] Intelligent monitoring function: The humidity sensor 8 in the conductivity electrode storage tank 1 detects the humidity in the chamber in real time. When the humidity is lower than the preset threshold, such as 50%RH, the external alarm module will activate the indicator light or the buzzer will sound to remind the staff to add water by adding wet cotton or other means; The liquid level sensor 9 in the pH electrode storage tank 2 continuously monitors the KCL solution level. When the liquid level is lower than the minimum immersion height of the probe's sensitive membrane, the alarm module will be triggered to prompt the replenishment of KCL solution.

[0025] Probe removal: Rotate the probe in the opposite direction, and the positioning ring 12 will unscrew along the thread of the annular fixing block 4 to remove the probe. The central hole of the circular sealing sleeve 7 will automatically retract when there is no probe, maintaining the sealed state inside the tank.

[0026] The implementation principle of the integrated intelligent maintenance storage tank for conductivity electrodes in this application embodiment is as follows: When the conductivity electrode probe 13 and pH electrode probe 14 have been used, and it is not immediately clear which maintenance storage tank they should be placed in, the conductivity electrode probe 13 is picked up and moved from top to bottom along with the corresponding annular magnet 10. Note that the conductivity electrode probe 13 should not be inserted into the maintenance storage tank; it should only be kept close to one of the annular magnets 3 from top to bottom. Because magnets have the basic property of "like poles repel, unlike poles attract," when the annular magnet 10 is close to the correct annular magnet 3, attraction will occur; when the annular magnet 10 is close to the incorrect annular magnet 3, repulsion will occur. This feature warns the operator not to put the probe into the maintenance storage tank. When placing the conductivity electrode probe 13 and pH electrode probe 14 into the correct conductivity electrode storage tank 1 and pH electrode storage tank 2, rotate the probe to drive the positioning ring 12 to rotate into the interior of the annular fixing block 4. The positioning ring 12 is threadedly connected to the inner wall of the annular fixing block 4. Finally, it drives the pressure plate 11 to fit together with the sealing gasket 5, which has a sealing effect. At the same time, because the circular sealing sleeve 7 has a small hole in the middle, it is easy for the probe to enter. The circular sealing sleeve 7 is made of highly elastic rubber. When the circular sealing sleeve 7 is not in contact with the corresponding probe, the small hole will shrink very small to prevent dust from entering. The conical sealing cylinder 6 is also made of rubber.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
