Description

Technical Field

[0001] This utility model relates to the field of electrochemical mixer technology, and in particular to an electrochemical solution mixing structure. Background Technology

[0002] Electrochemical stripping voltammetry for heavy metal detection comprises two processes: electrolytic enrichment and electrolytic stripping. Electrolytic enrichment involves electrolyzing the test solution at a set constant potential, concentrating heavy metal ions onto the surface of the electrochemical sensor. To improve the enrichment effect, the electrochemical sensor can be rotated relative to the solution to mix the solution and accelerate the transport of the analyte to the sensor surface. The amount of enriched substance depends on factors such as the sensor potential, area, electrolysis time, and mixing rate.

[0003] Traditional electrochemical solution mixing devices typically use a single-bearing structure to position the rotating component. When the rotation speed increases, the insufficient positioning accuracy of the rotating component will cause significant vibration and noise, affecting the working environment and hindering solution mixing.

[0004] Therefore, it is necessary to provide a novel electrochemical solution mixing device to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide an electrochemical solution mixing structure that can serve as a guide and limiter, reduce friction and noise, and enable the rotating cylinder to reach a higher speed to quickly achieve the purpose of solution mixing.

[0008] A sample cell, which is detachably mounted on a rotating cylinder;

[0009] A lifting assembly is provided, the bottom of which is connected to a base, and an electrochemical sensor is installed at the top of the lifting assembly. The lifting assembly can move the electrochemical sensor so that it extends into the sample cell.

[0010] Preferably, the rotating cylinder is fitted with two bearing limiting rings at intervals, and the two bearing limiting rings are installed adjacent to each other in a one-to-one correspondence with the two bearings.

[0011] Preferably, the positioning seat is detachably mounted on the base, and the sample cell passes through the positioning seat.

[0012] Preferably, the electrochemical solution mixing device further includes a sensor mounting base, which is connected to the lifting assembly, and the electrochemical sensor is connected to the sensor mounting base.

[0014] Preferably, the mounting sleeve has an internal thread, and the electrochemical sensor is threadedly connected to the mounting sleeve.

[0015] Compared with existing technologies, the advantages are that by installing two bearings, the system can guide and limit movement, reduce friction and noise, and allow the rotating cylinder to reach a higher speed to quickly achieve the purpose of mixing the solution.

[0020] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0021] It should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship 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, and 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. Therefore, they should not be construed as limitations on this utility model.

[0022] It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. Additionally, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0024] Please see Figures 1 to 2 This utility model provides an electrochemical solution mixing structure, including a base 1, a drive component 2 installed inside the base 1, a rotating shaft 21 mounted on the drive component 2, the rotating shaft 21 extending from the base 1, and a rotating cylinder 5 connected to the rotating shaft 21, and two bearings 3 spaced apart on the rotating cylinder 5, the outer rings of the two bearings 3 contacting the inner wall of the base 1. By installing the two bearings 3, it can play a guiding and limiting role, and can also reduce friction and noise, so that the rotating cylinder 5 can reach a higher rotation speed to quickly achieve the purpose of solution mixing.

[0025] Positioning seat 6, which surrounds the outside of the rotating cylinder and is mounted on the base 1;

[0026] Sample cell 8, which is detachably mounted on the rotating cylinder 5;

[0027] A lifting assembly 11 is provided, with its bottom end connected to the base and its top end equipped with an electrochemical sensor 9. The lifting assembly 11 can move the electrochemical sensor 9 to extend it into the sample cell 8. It should be noted that in this embodiment, the driving component 2 is a motor, and the lifting assembly 11 can be a cylinder or a hydraulic cylinder.

[0028] In use, the sample cell 8 contains the test solution. The lifting assembly 11 descends to lower the height of the electrochemical sensor 9, immersing one end of the sensor 9 in the test solution. The driving component 2 drives the rotating cylinder 5 to rotate via the rotating shaft 21. The sample cell 8, placed inside the rotating cylinder 5, rotates synchronously with it. The positioning seat 6 does not rotate with the rotating cylinder 5. The test solution in the sample cell 8 also rotates, creating relative motion between the test solution and the electrochemical sensor 9, thus achieving a mixing effect and ensuring the solution is homogenized. Furthermore, the outer rings of both bearings 3 are in contact with the inner wall of the base 1. Installing two bearings 3 provides guidance and positioning, reduces friction and noise, and allows the rotating cylinder 5 to reach a higher rotation speed for faster solution mixing.

[0029] In a preferred embodiment, two bearing retaining rings 4 are spaced apart on the rotating cylinder 5, and the two bearing retaining rings 4 are installed adjacent to the two bearings 3 in a one-to-one correspondence. In this way, the two bearing retaining rings 4 can limit the movement of the two bearings 3 respectively.

[0030] In a preferred embodiment, the positioning seat 6 is generally cylindrical and is detachably mounted on the base 1. The sample cell 8 passes through the positioning seat 6 and protrudes outside the base 1. This provides sufficient space for the sample cell 8 to rotate.

[0031] In a preferred embodiment, the electrochemical solution mixing device further includes a sensor mounting base 10, which is connected to the lifting assembly 11, and the electrochemical sensor 9 is connected to the sensor mounting base 10. This facilitates the installation of the electrochemical sensor 9 and increases its installation reliability.

[0032] In a preferred embodiment, the electrochemical solution mixing device further includes a mounting sleeve 12, which is detachably mounted on the sensor mounting base 10, and the electrochemical sensor 9 is detachably connected to the mounting sleeve 12. Specifically, the mounting sleeve 12 has an internal thread, and the electrochemical sensor 9 is threadedly connected to the mounting sleeve 12, facilitating the detachable connection of the electrochemical sensor 9 to the sensor mounting base 10.

[0033] During operation, the sample cell 8 contains the test solution. The lifting assembly 11 descends to lower the height of the electrochemical sensor 9, immersing one end of the sensor 9 in the test solution. The driving component 2 drives the rotating cylinder 5 to rotate via the rotating shaft 21. The sample cell 8, placed inside the rotating cylinder 5, rotates synchronously with it, causing the test solution in the sample cell 8 to rotate as well. This relative motion between the test solution and the electrochemical sensor 9 achieves a mixing effect, ensuring the solution is thoroughly mixed. The two bearings 3 guide and limit the rotation of the rotating cylinder 5, reducing friction and noise, allowing the rotating cylinder 5 to reach higher speeds for faster solution mixing.

[0034] Since the above actions have achieved the goal of uniform mixing of the test solution, when using an electrochemical detection instrument, the more uniform the texture of the test solution, the higher the accuracy of the measurement results, which is beneficial to improving the detection precision of the electrochemical detection instrument.

[0035] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
