Description

Technical Field

[0001] The invention relates to the technical field of moisture meter, in particular to a volumetric moisture meter with reusable electrolyte. Background Art

[0002] The principle of the electrolyte moisture meter is to use the reaction between Karl Fischer reagent and water. Specifically, when the Karl Fischer reagent in the electrolytic cell of the instrument reaches equilibrium, a water-containing sample is injected. Water participates in the redox reaction of iodine and sulfur dioxide. In the presence of pyridine and methanol, pyridine hydroiodide and pyridine methyl sulfate are generated. The consumed iodine is electrolyzed at the anode, thereby allowing the redox reaction to continue until all the water is consumed. According to Faraday's law of electrolysis, the iodine produced by electrolysis is directly proportional to the amount of electricity consumed during electrolysis, thereby determining the water content in the solvent.

[0003] In actual operation, when the solvent to be measured is sampled through a syringe and injected into the measuring instrument, if the syringe is offset too far, the sealed rubber sleeve will not be able to effectively isolate the external water vapor, which will affect the measurement results.

[0004] When the solvent is added, it takes a certain amount of time to fully mix with the electrolyte. Because multiple measurements will also cause the concentration of the electrolyte to change, which will affect the contact efficiency with the measured solvent, in order to increase the number of times the electrolyte is used, it is necessary to design a method to avoid frequent replacement of the electrolyte due to changes in the concentration of the electrolyte caused by multiple measurements.

[0005] Therefore, the present invention provides a volumetric moisture meter with reusable electrolyte to solve the above problems. Summary of the invention

[0036] The following will refer to the attached Figures 1 to 9 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0037] A volumetric moisture meter with reusable electrolyte, as shown in the attached Figure 1 -Attached Fig. 9 The main unit 1 includes a host 1, a titration cup 2 and an injection syringe 18. The titration cup 2 is the place where the water sample is actually measured. The titration cup 2 is installed on the main unit 1. The main unit 1 measures the water content of the solvent added to the titration cup 2. The titration cup 2 is provided with a drying cylinder 3 for absorbing the water vapor inside the titration cup 2. The front side of the main unit 1 is provided with a central control screen 5. Both sides of the central control screen 5 are provided with instrument keyboards for controlling the main unit 1. The drying cylinder 3, the central control screen 5 and the instrument keyboard are all prior art and will not be described in detail.

[0038] The top of the titration cup 2 is provided with a top cover 6 for sealing, and a liquid adding tube 9 is connected to the side of the top cover 6 close to the titration cup 2. The liquid adding tube 9 is connected to an external device through a connecting hose 4, and the external device is used to add a measuring reagent into the titration cup 2. The main function of the external device is to prevent the user from directly contacting the KF reagent and to simplify the user's operation. It is an auxiliary device designed, including the functions of KF reagent inlet and outlet.

[0039] An inner ring 7 is provided at the bottom of the top cover 6, and an outer ring 8 is provided at the top of the titration cup 2. The top cover 6 and the titration cup 2 are connected via the inner ring 7 and the outer ring 8, and the titration cup 2 is sealed by inserting the inner ring 7 and the outer ring 8. When the titration cup 2 needs to be sealed, the top cover 6 is moved to the top of the titration cup 2, and then the inner ring 7 is aligned with the outer ring 8, and the top cover 6 is pressed downward so that the top cover 6 seals the titration cup 2. It should be noted that in the process of installing the top cover 6 on the titration cup 2, the energy storage gear 12 will mesh with the inner side of the rotating gear ring 29, which is convenient for the subsequent liquid inlet stirring process.

[0040] Example 1

[0041] This embodiment is designed to solve the problem that external water vapor may enter the titration cup 2 during the process of adding material to the injection syringe 18 .

[0042] The bottom of the top cover 6 is connected to a sealing mechanism for limiting the position of the injection syringe 18, and the sealing mechanism includes an energy storage gear 12 rotatably connected to the bottom of the top cover 6, and a lower barrel 11 is connected to the middle position of the energy storage gear 12. The injection syringe 18 adds solvent to the titration cup 2 through the lower barrel 11. A sealing rubber sleeve 17 is provided in the lower barrel 11, and a downward movement groove 21 is opened on the inner side wall of the lower barrel 11. A downward movement rod 22 is slidably connected to the inner side wall of the downward movement groove 21, and a downward pressure ring 20 is fixedly connected to the bottom end of the downward movement rod 22. A downward pressure plate 19 is fixedly connected to the outer side wall of the injection syringe 18, and the lower pressure plate 19 pushes the downward pressure ring 20 downward by contact and pressing during the downward movement process.

[0043] When testing the moisture content of the solvent to be measured, the user sucks the solvent into the injection syringe 18 through the injection syringe 18, and then extends the injection syringe 18 into the discharge barrel 11. The injection syringe 18 will push the central part of the sealing rubber sleeve 17 that maintains the seal, and the other parts of the sealing rubber sleeve 17 will be tightly attached to the injection syringe 18, thereby maintaining a sealed state (if the injection syringe 18 moves too far to one side, the sealing rubber sleeve 17 will not be able to stick to the side wall of the injection syringe 18). When the injection syringe 18 continues to move downward, the lower pressing plate 19 on the injection syringe 18 will contact the lower pressing ring 20 and push the lower pressing ring 20 downward.

[0044] The interior of the lower barrel 11 is connected to a clamping arc plate 24 via a telescopic rod 25. A guide block 27 is provided on the top of the clamping arc plate 24 to facilitate the downward movement of the injection syringe 18. A fixing spring 23 is provided between the lower moving rod 22 and the inner side wall of the lower moving groove 21. The lower moving rod 22 is connected to the clamping arc plate 24 via a transmission rod 26. During the downward movement of the lower moving rod 22, the clamping arc plate 24 is driven by the transmission rod 26 to be pushed toward the direction of the injection syringe 18.

[0045] As mentioned above, when the injection syringe 18 continues to move downward, the downward pressure ring 20 will be pushed downward synchronously through the downward pressure sheet 19 on its surface. The downward movement of the downward pressure ring 20 will cause the downward movement rod 22 to move downward synchronously. At this time, the downward movement rod 22 will push the clamping arc plate 24 to move toward the injection syringe 18 under the action of the transmission rod 26, thereby limiting the position of the injection syringe 18 to prevent it from shifting to one side when in the discharge barrel 11, ensuring the sealing performance of the sealing rubber sleeve 17 when in contact with the injection syringe 18, preventing external water vapor from entering the titration cup 2, and ensuring the accuracy of moisture measurement.

[0046] Example 2

[0047] This embodiment enables the lower barrel 11 to rotate while being pushed downward by the injection syringe 18, thereby realizing the effect of energy storage, making it convenient for the subsequent injection syringe 18 to stir the reagent and electrolyte after leaving the lower barrel 11, so that they can be fully mixed and the measurement efficiency is improved.

[0048] A driving ring 10 is fixedly connected to the top of the top cover 6, and an arc-shaped rotating port 13 is opened on the driving ring 10. The lower barrel 11 is located on the inner side of the driving ring 10, and a lower slide shaft 14 is fixedly connected to the outer wall of the lower barrel 11. When the lower barrel 11 moves downward, the rotating port 13 drives the lower barrel 11 to move downward and rotates at the same time;

[0049] Two limit blocks 16 are fixedly connected to the inner side of the energy storage gear 12. A sliding groove 15 corresponding to the limit blocks 16 is opened on the lower barrel 11. The limit blocks 16 and the inner side walls of the sliding groove 15 can slide relative to each other, and the lower barrel 11 can slide relative to the energy storage gear 12 in the vertical direction.

[0050] As described in Example 1, the injection syringe 18 enters the lower barrel 11 and contacts the pressing ring 20 to press the lower barrel 11 downward as a whole. Due to the relative sliding between the slide groove 15 and the limit block 16, the lower barrel 11 can move downward relative to the energy storage gear 12, and in the process of the lower barrel 11 moving downward, refer to the attached Figure 3 Under the guidance of the arc-shaped rotating opening 13 , the lower slide shaft 14 synchronously rotates the discharge barrel 11 , so that the energy storage gear 12 rotates with the rotation of the discharge barrel 11 .

[0051] The lower barrel 11 passes through the top cover 6, and a return spring 28 is provided between the outer wall of the lower barrel 11 and the bottom of the top cover 6. The return spring 28 is used to return the lower barrel 11 after being pressed down. In the process of the lower barrel 11 moving downward, the return spring 28 will be stretched, thereby accumulating energy, and when the injection syringe 18 is separated from the lower barrel 11, the lower barrel 11 will move upward and return to its original position.

[0052] Example 3

[0053] This embodiment is a supplementary explanation to Embodiment 2. When the lower barrel 11 moves downward and accumulates energy through the return spring 28, the electrolyte is stirred, and when the return spring 28 releases energy, the solvent and the electrolyte are further mixed, thereby improving the measurement efficiency of the measuring instrument.

[0054] A mixing mechanism is provided in the titration cup 2 for fully mixing the added solvent and the electrolyte. The mixing mechanism comprises a rotating gear ring 29 rotatably connected to the top of the inner wall of the titration cup 2 , wherein the energy storage gear 12 and the rotating gear ring 29 are adapted to each other.

[0055] The lower end of the rotating gear ring 29 is fixedly connected to two symmetrically arranged push rods 30, and the inner side wall of the titration cup 2 is fixedly connected to a first guide arc 31 and a second guide arc 32, the first guide arc 31 and the second guide arc 32 are symmetrically arranged, and the first guide arc 31 and the second guide arc 32 are both arc-shaped, and a sliding opening 33 is opened on the push rod 30, and the height of the sliding opening 33 corresponds to the height of the first guide arc 31 and the second guide arc 32 in the vertical direction;

[0056] A sliding block 34 corresponding to the first guide arc 31 and the second guide arc 32 is provided in the sliding opening 33. The two sliding blocks 34 move in the sliding opening 33 through the first guide arc 31 and the second guide arc 32 respectively. A guide arc plate 35 is provided on the sliding block 34, and the two guide arc plates 35 are arranged opposite to each other.

[0057] When the push rod 30 rotates, it drives the sliding block 34 to move along the first guide arc 31 or the second guide arc 32 . At this time, the sliding block 34 moves up or down in the sliding opening 33 .

[0058] When the injection syringe 18 extends into the lower barrel 11 and pushes the lower barrel 11 downward, the energy storage gear 12 rotates clockwise, driving the corresponding rotating gear ring 29 to rotate clockwise. When the rotating gear ring 29 rotates clockwise, Figure 8 The push rod 30 on the right side will move toward the upper direction of the second guide arc 32, and drive the right guide arc plate 35 to move upward under the action of the second guide arc 32 and the sliding block 34; and the push rod 30 on the right side will move toward the bottom end of the first guide arc 31, driving the corresponding guide arc plate 35 to move downward, so as to achieve the following Fig. 9 The arrow in the figure indicates the flow direction of the electrolyte, thereby accelerating the flow of the electrolyte and avoiding the situation where the concentration of the electrolyte at the injection solvent position is reduced due to repeated use and inaccurate detection. When the injection syringe 18 injects the reagent into the electrolyte, the needle should be below the liquid level to facilitate the mixing of the reagent and the electrolyte.

[0059] Similarly, when the injection syringe 18 is separated from the lower barrel 11, the return spring 28 will contract, so that the lower barrel 11 can move up, and at the same time, it rotates counterclockwise under the action of the rotating mouth 13, synchronously causing the energy storage gear 12 to rotate counterclockwise, driving the rotating gear ring 29 to rotate counterclockwise, thereby achieving the electrolyte and the added solvent such as the attached Fig. 9 The two substances flow in the opposite direction indicated by the arrow, which speeds up the mixing of the two and improves the measurement efficiency.

[0060] The inner bottom of the titration cup 2 is rotatably connected to a transmission gear 38, which meshes with the teeth on the inner side of the stirring gear ring 37, and the outer side wall of the stirring shaft 39 is fixedly connected to a rotating gear 41, which meshes with the transmission gear 38 and the rotating gear 41. The bottom end of the push rod 30 is fixedly connected to a stirring block 36 for pushing the electrolyte to flow, and a stirring gear ring 37 is fixedly connected between the two stirring blocks 36. The inner bottom of the titration cup 2 is rotatably connected to a stirring shaft 39, and the outer side wall of the stirring shaft 39 is fixedly connected to a stirring rod 40 for stirring the electrolyte.

[0061] When the push rod 30 rotates, the two stirring blocks 36 at the bottom can rotate, and the electrolyte is stirred horizontally during the flow of the electrolyte, thereby accelerating its stirring speed. The stirring blocks 36 will synchronously drive the stirring gear ring 37 to rotate, and the stirring gear ring 37 will rotate the stirring shaft 39 through the transmission action of the transmission gear 38 and the rotating gear 41. It should be noted that the rotation direction of the stirring shaft 39 is opposite to that of the stirring block 36, thereby increasing the degree of mixing after the reagent and the electrolyte come into contact, thereby increasing the measurement speed of the reagent.

[0062] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0063] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
