An automated moisture analyzer

Abstract

This invention provides an automated moisture analyzer. The automated moisture analyzer includes: a main unit with a mounting base on its upper surface; and a moisture cup, which is placed on the mounting base. The moisture cup has a sample dispensing port, an electrode mounting port for inserting a detection electrode, and a burette mounting port for dispensing titrant. The sample dispensing port is switchable between an open and closed state, and is used to dispense the sample when it is open.

Description

Technical Field

[0001] This utility model relates to the field of article detection technology, specifically to an automated moisture analyzer. Background Technology

[0002] In industries such as pharmaceuticals, chemicals, food, and new energy, moisture content can affect the processing technology, lifespan, usability, and quality of many products, making the monitoring of moisture content crucial. Most products have optimal moisture content for their manufacturing processes, and regulations also impose strict limits on the moisture content of certain products; therefore, moisture content measurement using a moisture analyzer is necessary.

[0003] The Karl Fischer Moisture Meter is a type of moisture analyzer known for its high accuracy and wide applicability, making it widely used in fields such as chemistry, pharmaceuticals, food, cosmetics, agriculture, and electronics. Based on the principle of electrochemical titration, the Karl Fischer reagent reacts with water to quantify the moisture content of the sample.

[0004] Existing moisture analyzers require manual removal of the detection electrodes and other components from the moisture cup, followed by the addition of the sample to be tested, and then reinstallation of the components. This results in low work efficiency, especially for the determination of certain complex samples (such as high-viscosity or high-boiling-point samples), which may require special handling and increase the operational difficulty. Furthermore, Karl Fischer reagent has a certain degree of toxicity, which can harm the health of operators and cause serious safety accidents. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, embodiments of this utility model provide an automated moisture analyzer. The automated moisture analyzer includes: a main unit with a mounting base on its upper surface; and a moisture cup, which is placed on the mounting base. The moisture cup has a sample dispensing port, an electrode mounting port for inserting a detection electrode, and a burette mounting port for dispensing titrant. The sample dispensing port is switchable between an open and closed state, and when open, it is used to dispense the sample to be tested.

[0006] For example, the automated moisture meter also includes a positioning mechanism, which includes a positioning frame and a positioning post connected to the main unit. The moisture cup is also provided with a positioning hole. The positioning post is movably connected to the positioning frame between being inserted into the positioning hole and being removed from the moisture cup. The positioning post is used to position the moisture cup in the desired position on the mounting base when inserted into the positioning hole.

[0007] For example, one end of the positioning post that can be inserted into the positioning hole is conical in shape and gradually expands toward the inside of the positioning post; and / or the automated moisture analyzer also includes a diaphragm generating electrode, and the positioning hole is configured to allow insertion of the positioning post or the diaphragm generating electrode.

[0008] For example, the positioning mechanism also includes a locking element that connects and secures the water cup when it is positioned in the intended location.

[0009] For example, the automated moisture analyzer also includes a sealing mechanism, which includes a drive member and a suction cup connected to the drive end of the drive member. The suction cup can be sealed to the sample dispensing hole under the drive of the drive member so that the sample dispensing hole is in a closed state, and can be detached from the sample dispensing hole so that the sample dispensing hole is in an open state.

[0010] For example, the driving component includes a lifting cylinder and a rotating cylinder. The driving end of the lifting cylinder is connected to the body of the rotating cylinder to drive the rotating cylinder to move up and down along the axial direction of the sample feeding hole. The sealing mechanism also includes a connector and a sealing component. The connector is connected between the driving end of the rotating cylinder and the suction cup. The suction cup can rotate in a plane perpendicular to the axis under the drive of the rotating cylinder. The connector is provided with an exhaust hole communicating with the suction cup cavity. The sealing component seals the exhaust hole when the suction cup seals to the sample feeding hole.

[0011] For example, the automated moisture analyzer also includes a titrant supply assembly, which includes a base and a titrant bottle disposed on the base. The titrant bottle is connected to a burette mounting hole to add titrant into a moisture cup.

[0012] For example, the base is also provided with a level detector for detecting the level of titrant in the titrant bottle.

[0013] For example, the water cup is constructed as a single piece; and / or the water cup is constructed as a cylindrical glass cup with a wall thickness between 1 mm and 2 mm.

[0014] For example, the automated moisture analyzer also includes a sample dispensing device for dispensing the sample to be tested into the moisture cup through an open dispensing orifice.

[0015] The moisture analyzer provided in this embodiment of the invention has a dedicated sample dispensing port, eliminating the need for operators to disassemble or assemble detection electrodes and other components during sample addition. Furthermore, the sample dispensing port can be switched to an open state when dispensing is needed and to a closed state during the reaction process, resulting in a high degree of automation. Based on this, the sample dispensing port can be integrated with a sample addition device to facilitate automated sample addition. In summary, the moisture analyzer reduces operator workload, improves work efficiency, and decreases the probability of health risks from the toxicity of the titrant, thus offering high safety.

Detailed Implementation

[0024] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0025] This utility model provides an automated moisture analyzer (hereinafter referred to as a moisture analyzer). A moisture analyzer is also called a moisture meter, water content analyzer, rapid moisture analyzer, water meter, moisture detector, moisture measuring instrument, moisture analyzer, water content detector, water meter, hygrometer, and trace moisture analyzer. The moisture analyzer can be applied to any suitable device, including but not limited to pipetting devices or measuring devices. The moisture analyzer of this utility model embodiment will be described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 3 As shown, the moisture analyzer 100 may include a main unit 200 and a moisture cup 300.

[0027] The main unit 200 can serve as the base for the moisture analyzer 100, and can be mounted on a device such as the platform of a pipetting apparatus. A mounting base 210 can be provided on the upper surface of the main unit 200. Components such as a magnetic stirrer can be installed inside the main unit 200.

[0028] The moisture cup 300 can be placed on the mounting base 210. The mounting base 210 can have any suitable structure, including but not limited to a support plate, claws, or slots. Exemplarily, the moisture cup 300 can be fixed to the mounting base 210 by being clamped or otherwise secured; alternatively, the moisture cup 300 can simply sit on the mounting base 210. The moisture cup 300 can be detached from the mounting base 210 by a robotic arm or manually to facilitate cleaning and drying of the moisture cup 300.

[0029] The water cup 300 may be provided with a sample dispensing port 310, an electrode mounting port 320, and a burette mounting port 330. The sample dispensing port 310, electrode mounting port 320, and burette mounting port 330 may be located at any suitable position on the water cup 300, such as the upper part. For example, the sample dispensing port 310, electrode mounting port 320, and burette mounting port 330 may be located at the top of the water cup 300.

[0030] The sample dispensing port 310 can be switched between an open and closed state. The switching method is arbitrary; for example, it can be achieved by sealing the sample dispensing port 310 with a sealing plug, or by the sample dispensing port 310 itself having an opening and closing function. When the sample dispensing port 310 is in the open state, it can be used to add the sample to be tested. That is, the sample to be tested can be added into the moisture cup 300 through the open sample dispensing port 310. When the sample dispensing port 310 is in the closed state, the sample to be tested cannot pass through the sample dispensing port 310. The sample to be tested includes, but is not limited to, milk powder, emulsion, active pharmaceutical ingredient, or catalyst. The electrode mounting hole 320 can be used to insert a detection electrode (not shown). Therefore, the moisture analyzer 100 may also include a detection electrode. The burette mounting hole 330 can be used to add a titrant. The titrant may include an anolyte or Karl Fischer reagent. That is, the titrant can be added into the moisture cup 300 through the burette mounting hole 330. A burette mounting hole 330 can be used to insert a burette (not shown). The titrant can enter the moisture cup 300 through the burette. Therefore, the moisture analyzer 100 may also include a burette. A drain pipe mounting hole 350 may also be provided on the moisture cup 300. After the moisture measurement is completed, the drain pipe mounting hole 350 can be used to drain the liquid in the moisture cup 300. The drain pipe mounting hole 350 can be used to insert a drain pipe (not shown). The liquid in the moisture cup 300 can exit the moisture cup 300 through the drain pipe. Therefore, the moisture analyzer 100 may also include a drain pipe. It should be noted that the burette mounting hole 330 and the drain pipe mounting hole 350 may be directly provided on the moisture cup 300, or they may be indirectly provided on the moisture cup 300 through other components. Exemplarily, the moisture analyzer 100 may also include a sealing liquid filling integrated component 400. An integrated component mounting hole 360 ​​may also be provided on the moisture cup 300. The sealed liquid filling unit 400 can be connected to the unit mounting hole 360. A burette mounting hole 330 and a drain pipe mounting hole 350 can be provided on the sealed liquid filling unit 400. Exemplarily, the burette mounting hole 330 and the drain pipe mounting hole 350 can extend vertically. This allows the burette to extend vertically, enabling the titrant to enter the water cup 300 vertically, preventing the titrant from shifting and affecting the magnetic stirring effect and the water content measurement results.

[0031] In practical applications, the moisture content of the 100 moisture meter can be measured by following these steps:

[0032] Sample preparation stage: Titrate is added to the water cup 300 through the burette mounting hole 330. Then, the sample dispensing hole 310 can be switched to the open state, and the sample to be tested can be added to the water cup 300 through the sample dispensing hole 310 to form a solution within the water cup 300. Then, the sample dispensing hole 310 can be switched to the closed state to keep the water cup 300 closed during the following reaction process. The solvent can be selected according to actual needs, for example, methanol. The order of adding the sample to be tested and the solvent can be determined according to actual needs.

[0033] Titration process: The titrant in the water cup 300 reacts with the water in the sample. During this process, the solution in the water cup 300 can be rotated by the magnetic stirrer in the main unit 200 or manually to increase the reaction rate.

[0034] Potential change detection stage: As the titrant reacts with water in the sample, the potential of the detection electrode changes. When the reaction reaches its endpoint, the electrochemical signal (such as a potential jump) will change abruptly, indicating that the water has been completely consumed, i.e., the reaction has reached its endpoint.

[0035] Calculation results stage: Based on the amount of titrant consumed, the moisture content in the sample to be tested is calculated.

[0036] Once the calculation is complete, the liquid in the moisture cup 300 can be drained through the drain pipe mounting hole 350. Then, the moisture cup 300 can be cleaned and dried to prepare for the next moisture measurement.

[0037] In summary, the moisture analyzer 100 provided in this embodiment of the invention, having a dedicated sample dispensing port 310, eliminates the need for operators to disassemble or assemble detection electrodes and other components during sample addition. Furthermore, the sample dispensing port 310 can be switched to an open state when sample addition is needed and to a closed state during the reaction process, thus achieving a high degree of automation. Based on this, the sample dispensing port 310 can be integrated with a sample addition device to facilitate automated sample addition. In conclusion, the moisture analyzer 100 reduces operator workload, improves work efficiency, and decreases the probability of health risks from the toxicity of the titrant, thus ensuring high safety.

[0038] Exemplarily, the moisture analyzer 100 may also include a sample dispensing device (not shown). The sample dispensing device can be used to add the sample to be tested into the moisture cup 300 through the open dispensing port 310. The dispensing device includes, but is not limited to, a pipette device, a pump device, or a robotic arm. After the sample dispensing device adds the sample to be tested into the moisture cup 300, the dispensing port 310 can be switched to a closed state to keep the moisture cup 300 closed during the reaction. This configuration increases the automation level of the moisture analyzer 100, thereby further reducing the workload of operators and improving work efficiency.

[0039] Exemplarily, the moisture meter 100 may further include a positioning mechanism 500. The positioning mechanism 500 can be connected to the moisture cup 300 to position the moisture cup 300 at a desired location on the mounting base 210. The positioning mechanism 500 includes, but is not limited to, a gripper positioning mechanism, a snap-fit ​​positioning mechanism, or a suction cup positioning mechanism. In some embodiments, the positioning mechanism 500 may include a positioning frame 510 and a positioning post 520. The positioning frame 510 can be connected to the main unit 200. The positioning post 520 can be movably connected to the positioning frame 510 in a vertical direction or any other suitable direction. A positioning hole 340 may also be provided on the moisture cup 300. The positioning hole 340 can be located at any suitable position on the moisture cup 300, such as the upper part. Exemplarily, the positioning hole 340 can be located at the top of the moisture cup 300. When the positioning post 520 moves relative to the positioning bracket 510, it can be adapted to be inserted into the positioning hole 340 to position the water cup 300 in the desired position on the mounting base 210, or the positioning post 520 can be detached from the water cup 300. To avoid misinsertion, the positioning post 520 can only be adapted to be inserted into the positioning hole 340, that is, the positioning post 520 only fits the size of the positioning hole 340. In other words, the positioning post 520 cannot be adapted to the size of the sample dispensing hole 310, the electrode mounting hole 320, or the burette mounting hole 330, and therefore cannot be inserted into these holes.

[0040] In practical applications, after the moisture cup 300 is placed on the mounting base 210, the moisture cup 300 and the positioning column 520 can be moved so that the positioning column 520 is inserted into the positioning hole 340. In this way, the moisture cup 300 can be positioned at the desired location on the mounting base 210. This configuration ensures that structures such as the sample dispensing hole 310, electrode mounting hole 320, and burette mounting hole 330 are in the correct positions, thereby improving the accuracy of sample dispensing and other operations, and consequently enhancing the reliability of moisture determination.

[0041] For example, the positioning post 520 may include one end 523. One end 523 of the positioning post 520 can be inserted into the positioning hole 340. One end 523 of the positioning post 520 may be conical, gradually widening towards the inside of the positioning post 520. With this configuration, one end 523 of the positioning post 520 can preferentially be inserted into the positioning hole 340 with a smaller segment, thus providing better guidance for the insertion of the positioning post 520 into the positioning hole 340, thereby facilitating the positioning of the water cup 300.

[0042] Exemplarily, the moisture analyzer 100 may also include a diaphragm generating electrode (not shown). The positioning hole 340 may be configured to allow insertion of either the positioning post 520 or the diaphragm generating electrode. That is, the positioning post 520 and the diaphragm generating electrode may be selectively inserted into the positioning hole 340. After the positioning post 520 is inserted into the positioning hole 340 to position the moisture cup 300, the positioning post 520 can be disengaged from the positioning hole 340, and then the diaphragm generating electrode can be inserted into the positioning hole 340. The diaphragm generating electrode is a special electrode whose working principle is based on the conductivity of electrolytes. During moisture determination, the diaphragm generating electrode contacts the sample to be tested, utilizing the migration and transformation of electrolytes under the influence of an electric field to achieve rapid and accurate moisture determination. The diaphragm generating electrode not only has high sensitivity but also can adapt to various complex environmental conditions, ensuring the stability and reliability of the measurement results. The diaphragm generating electrode material is typically made of high-purity metal or alloy to ensure good conductivity and corrosion resistance. The diaphragm generating electrode also has excellent anti-interference capabilities. Depending on the titrant and / or the sample to be tested, a detection electrode and / or a diaphragm generating electrode can be selected to determine when the reaction has reached its endpoint. Therefore, the moisture analyzer 100 has a wide range of applications.

[0043] Exemplarily, the positioning mechanism 500 may also include a locking element (not shown). When the moisture cup 300 is positioned in the intended location, the locking element can connect to and secure the moisture cup 300. The locking element can secure the moisture cup 300 by connecting it to any suitable component such as the main unit 200 or the positioning frame 510. The locking element includes, but is not limited to, screws, grippers, or clips. By providing the locking element, the moisture cup 300 in the intended position can be fixed, preventing displacement of the moisture cup 300 during the aforementioned measurement steps, thus ensuring the stability and reliability of the measurement results.

[0044] The shape of the water cup 300 can be arbitrary, such as a cube or a sphere. The material of the water cup 300 can be arbitrary, such as plastic or glass. In some embodiments, the water cup 300 can be constructed as a single-piece structure. Compared to a split structure, a single-piece water cup 300 has higher mechanical strength and better sealing, making leakage less likely. The water cup 300 can be integrally formed by any suitable method such as casting or machining. In some embodiments, the water cup 300 can be constructed as a cylindrical glass cup. This shape of water cup 300 has a simpler structure, is easier to manufacture, and the glass is more transparent, making it easier to observe the reaction inside the water cup 300. The wall thickness of the glass cup can be between 1mm and 2mm, for example, 1mm, 1.5mm, or 2mm. When the wall thickness of the glass cup is greater than 2mm, the cost of the glass cup is higher, and magnetic force is not easily transmitted to the water cup 300, resulting in poor magnetic stirring effect. When the thickness of the glass cup is less than 1mm, the mechanical strength of the glass cup is too low, making it prone to breakage. Therefore, with a glass wall thickness between 1mm and 2mm, the mechanical strength and cost of the glass can be relatively balanced, and the magnetic force can be easily transmitted to the water cup within 300, resulting in a better magnetic stirring effect.

[0045] For the cylindrical water cup 300 shown in the figure, the mounting base 210 can be annular to fit the lower part of the water cup 300. After the water cup 300 is placed on the mounting base 210, the water cup 300 can be rotated so that the positioning hole 340 is directly below the positioning post 520. The positioning frame 510 can include a support rod 511 and a positioning plate 512. The support rod 511 can extend vertically, and its lower end can be connected to the mounting base 210. The positioning plate 512 can extend horizontally, and one end can be connected to the upper end of the support rod 511. Thus, the positioning frame 510 can generally be inverted L-shape. The positioning post 520 can pass through a hole at the other end of the positioning plate 512 to move vertically, thereby inserting and disengaging from the positioning hole 340. The positioning post 520 can include a rod segment 521 and a post segment 522. The rod segment 521 can pass through a hole at the other end of the positioning plate 512 to move vertically. The diameter of the column segment 522 can be larger than that of the rod segment 521. The upper end of the column segment 522 can be connected to the lower end of the rod segment 521, and the lower end of the column segment 522 can be one end 523 of the positioning post 520 for insertion into the positioning hole 340.

[0046] Exemplarily, the moisture analyzer 100 may also include a sealing mechanism 600. The sealing mechanism 600 may include a drive member 610 and a suction cup 620. The drive member 610 may be disposed on one side of the main unit 200. The suction cup 620 may be connected to the drive end of the drive member 610. The suction cup 620 can move under the drive of the drive member 610, thereby moving and sealing to the sample dispensing port 310, so that the sample dispensing port 310 is in a closed state. Furthermore, the suction cup 620 can move under the drive of the drive member 610, thereby moving and disengaging from the sample dispensing port 310, so that the sample dispensing port 310 is in an open state. The drive member 610 includes, but is not limited to, a motor and / or a cylinder. By providing the sealing mechanism 600, the sample dispensing port 310 can be switched more easily between an open state and a closed state, and the moisture analyzer 100 has a high degree of automation.

[0047] Exemplarily, the driving component 610 may include a lifting cylinder 611 and a rotary cylinder 612. The driving end of the lifting cylinder 611 may be connected to the body of the rotary cylinder 612 to drive the rotary cylinder 612 to move up and down along the axial direction of the sample dispensing orifice 310 (vertical in the embodiment shown in the figure). The sealing mechanism 600 may also include a connector 630 and a sealing element (not shown). The connector 630 may be connected between the driving end of the rotary cylinder 612 and the suction cup 620. With this configuration, the lifting cylinder 611 can drive the rotary cylinder 612, the suction cup 620, and the connector 630 to move up and down synchronously. Under the drive of the rotary cylinder 612, the suction cup 620 can rotate in a plane perpendicular to the axis of the sample dispensing orifice 310 (parallel to the horizontal in the embodiment shown in the figure). When moisture determination is required, the lifting cylinder 611 can drive the rotary cylinder 612, suction cup 620, and connector 630 to rise. Then, the rotary cylinder 612 can drive the suction cup 620 to rotate directly above the sample dispensing port 310 via the connector 630. The lifting cylinder 611 can then drive the rotary cylinder 612, suction cup 620, and connector 630 to descend, causing the suction cup 620 to press and seal against the sample dispensing port 310. This allows the sample dispensing port 310 to be switched to a closed state. Conversely, when it is necessary to install or remove the moisture cup 300 or switch the sample dispensing port 310 to an open state, the lifting cylinder 611 can drive the rotary cylinder 612, suction cup 620, and connector 630 to rise, allowing the suction cup 620 to detach from the sample dispensing port 310. Then, the rotary cylinder 612 can drive the suction cup 620 to rotate to the outside of the moisture cup 300 via the connector 630, preventing the suction cup 620 and connector 630 from interfering with the operation. The connector 630 may be provided with an exhaust port 631 that connects to the suction cup cavity of the suction cup 620. When the suction cup 620 presses against the sample dispensing port 310, air in the suction cup cavity of the suction cup 620 can be discharged through the exhaust port 631. Then, the sealing member can seal the exhaust port 631 to prevent air from entering the sample dispensing port 310 through the exhaust port 631, so that the suction cup 620 can be sealed to the sample dispensing port 310. In this way, during the process of sealing the suction cup 620 to the sample dispensing port 310, the lifting cylinder 611 does not need to continuously drive the rotating cylinder 612, the suction cup 620, and the connector 630 to descend, thereby preventing damage to the moisture cup 300 due to excessive pressing force. When it is necessary to switch the sample dispensing port 310 to the open state, the sealing member can disengage from the exhaust port 631, and air can enter the suction cup cavity of the suction cup 620 through the exhaust port 631. Driven by the lifting cylinder 611, the suction cup 620 can smoothly disengage from the sample dispensing port 310. The sealing components include, but are not limited to, screws or sealing plugs. The sealing components can be used to seal and remove the vent 631 by means of a robotic arm or manual operation.

[0048] Exemplarily, the moisture analyzer 100 may also include a titrant supply assembly 700. The titrant supply assembly 700 may be disposed on one side of the main unit 200. The titrant supply assembly 700 may include a base 710 and a titrant bottle 720. The titrant bottle 720 may be disposed on the base 710. The titrant bottle 720 may be connected directly or via a burette to the burette mounting hole 330 to add the titrant from the titrant bottle 720 into the moisture cup 300. With this configuration, the moisture analyzer 100 may also have a titrant dispensing function, resulting in a higher degree of automation.

[0049] For example, a level detector 730 may also be provided on the base 710. The level detector 730 can be used to detect the level of titrant in the titrant bottle 720. The level detector 730 includes, but is not limited to, a level gauge or a level sensor. By setting the level detector 730, the remaining amount of titrant in the titrant bottle 720 can be confirmed so that the titrant can be replenished in a timely manner.

[0050] In the description of this utility model, it should be understood that the directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" indicate the orientation or positional relationship, which are usually based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0051] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0052] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.
