Description

Technical Field

[0001] This utility model belongs to the field of residual chlorine analyzer calibration, specifically a residual chlorine analyzer calibration device. Background Technology

[0002] A residual chlorine analyzer is an instrument used to detect the residual chlorine content in water samples. Residual chlorine refers to the chlorine remaining in water after chlorination disinfection. There are three forms of residual chlorine: free residual chlorine, combined residual chlorine, and total residual chlorine. Residual chlorine is a routine item in water quality testing. In addition to drinking water, there are also strict discharge regulations for total residual chlorine in sewage. Therefore, residual chlorine analyzers are widely used in water plants, hospitals, health systems and other fields, playing an important role in water quality monitoring.

[0003] To ensure the accuracy of residual chlorine analyzers, they must be calibrated regularly. The purpose of calibration is to adjust the instrument readings by using standard solutions with known residual chlorine content to make them consistent with the actual residual chlorine content of the standard solutions. This ensures that the instrument can provide accurate and reliable measurement results in actual use.

[0004] The standard procedure for calibrating a residual chlorine analyzer is to immerse the electrode in a standard solution, observe the displayed value, and compare it with the value of the standard solution. If a difference exists, the instrument's accuracy needs to be adjusted. This process is repeated until the displayed value matches the value of the standard solution, at which point the residual chlorine analyzer is considered calibrated. During calibration, the electrode is usually held by hand or placed directly in a container of standard solution. Both methods have drawbacks. Since calibration can take several minutes to tens of minutes, or even longer, holding the electrode by hand increases manual labor and can cause arm pain and instability, leading to large fluctuations in the reading and affecting calibration. Placing the electrode directly in a container causes the probe to come into contact with the container wall, also resulting in unstable readings. Furthermore, collisions between the electrode probe and the container wall can cause damage, affecting its usability.

[0005] In summary, this invention provides a residual chlorine analyzer calibration device to solve the above-mentioned problems. Utility Model Content

A beaker 2 is provided on one side of the top of the base 1 for holding a standard solution.

The support assembly 5 includes a fixed plate 501, a movable plate 502, a second limiting hole 503, a second adjusting bolt 504, and a second threaded hole 505. Movable plates 502 are provided at both ends of the inner cavity of the fixed plate 501. One end of the movable plate 502 extends to the outside of the fixed plate 501. A fixing assembly 6 is installed on the surface of one end of the movable plate 502, and a stirring assembly 7 is installed on the surface of the other end of the movable plate 502. The fixing assembly 6 is used to fix the residual chlorine electrode 3. The fixing assembly 6 includes a fixing base 601, an elastic clamp 602, and a locking bolt 603. The fixing base 601 is fixedly connected to a movable plate 502 at one end. The elastic clamp 602 is fixed to the upper end of the surface of the fixing base 601. The residual chlorine electrode 3 is located in the inner cavity of the elastic clamp 602 and the fixing base 601. One end of the locking bolt 603 passes through the elastic clamp 602 and is threadedly connected to the elastic clamp 602. The second limiting hole 503 is opened on the surface of the movable plate 502. The top two ends of the fixing plate 501 are provided with second threaded holes 505. The top two ends of the fixing plate 501 are provided with second adjusting bolts 504. One end of the second adjusting bolt 504 passes through the second threaded hole 505 and extends into the inner cavity of the second limiting hole 503. The second adjusting bolt 504 is threadedly connected to the inner cavity of the second threaded hole 505.

[0024] like Figure 1-4 As shown, the inner cavity of beaker 2 is used to hold the standard solution. First, the standard solution is stirred by the stirring assembly 7 to make it evenly mixed. Then, the fixing plate 501 is rotated so that the fixing assembly 6 is above beaker 2. The second adjusting bolt 504 is loosened, and the movable plate 502 is pushed into the inner cavity of the fixing plate 501 or pulled outward from the fixing plate 501 to adjust the position of the fixing assembly 6. After adjustment, the second adjusting bolt 504 is tightened so that it extends into the inner cavity of the second limiting hole 503, thereby fixing the position of the movable plate 502. Then, the bottom of the residual chlorine electrode 3 passes through the elastic clip 602 and the fixing seat 601, extending it into the inner cavity of beaker 2 and immersing it in the standard solution.

[0025] Example 2

[0026] Reference Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, the lifting assembly 4 includes a fixed rod 401, a movable rod 402, a first adjusting bolt 403, a first threaded hole 404, and a first limiting hole 405. The lifting assembly 4 is used to provide support for the support assembly 5.

[0028] One end of the movable rod 402 is movably connected to the fixed plate 501 via a rotary damper, and the end of the movable rod 402 away from the fixed plate 501 extends into the inner cavity of the fixed rod 401 and is slidably connected to the inner cavity of the fixed rod 401.

[0029] The first limiting hole 405 is formed on the surface of the movable rod 402, the first threaded hole 404 is formed on the surface of the fixed rod 401, one end of the first adjusting bolt 403 passes through the first threaded hole 404 and extends into the inner cavity of the first limiting hole 405, and the first adjusting bolt 403 is threadedly connected to the inner cavity of the first threaded hole 404.

[0030] like Figure 3 As shown, the movable rod 402 is connected to the fixed plate 501 via a rotary damper, which allows for easy adjustment of the positions of the fixed component 6 and the stirring component 7. Loosening the first adjusting bolt 403 and pulling the movable rod 402 upwards raises the positions of the fixed component 6 and the stirring component 7, while pushing the movable rod 402 downwards lowers the positions of the fixed component 6 and the stirring component 7. This allows for adjustment of the positions of the fixed component 6 and the stirring component 7 according to usage requirements. After the position adjustment is completed, tightening the first adjusting bolt 403 extends the first adjusting bolt 403 into the inner cavity of the first limiting hole 405, thus fixing the adjusted position.

[0031] Example 3

[0032] Reference Figure 1-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0033] In this embodiment, the stirring assembly 7 includes a motor 701, a stirring shaft 702, and a stirring blade 703. The stirring assembly 7 is used to stir a standard solution.

[0034] The motor 701 is fixed to the surface of the movable plate 502 at the other end. The output shaft of the motor 701 passes through the movable plate 502 and is connected to the stirring shaft 702 for transmission. The end of the stirring shaft 702 away from the motor 701 is fixedly connected to the first adjusting bolt 403.

[0035] like Figure 1-4As shown, by rotating the fixed plate 501, the positions of the stirring assembly 7 and the fixed assembly 6 can be interchanged under the action of the rotation damper. Loosen the first adjusting bolt 403 and adjust the position of the stirring assembly 7 upward or downward so that the stirring blade 703 can extend into the inner cavity of the beaker 2.

When the stirring shaft 702 rotates, it drives the stirring blade 703 to rotate in the inner cavity of the beaker 2, thereby stirring the standard solution.

[0036] In use, first rotate the fixed plate 501. Under the action of the rotation damper, the positions of the stirring assembly 7 and the fixed assembly 6 can be interchanged. Loosen the first adjusting bolt 403 and adjust the position of the stirring assembly 7 upwards or downwards so that the stirring blade 703 can extend into the inner cavity of the beaker 2. Then tighten the first adjusting bolt 403 and start the motor 701. The output shaft of the motor 701 rotates, driving the stirring shaft 702 to rotate. When the stirring shaft 702 rotates, it drives the stirring blade 703 to rotate in the inner cavity of the beaker 2, thereby stirring the standard solution. After stirring is completed, rotate the fixed plate 501 again so that the fixed assembly 6 is above the beaker 2. Loosen the second adjusting bolt 504 and adjust the position of the fixed plate 501 upwards or downwards. The inner cavity of the fixed plate 501 pushes the movable plate 502, or pulls the movable plate 502 outward, thereby adjusting the position of the fixed component 6. After adjustment, the second adjusting bolt 504 is tightened so that the second adjusting bolt 504 extends into the inner cavity of the second limiting hole 503, thereby fixing the position of the movable plate 502. Then, the bottom of the residual chlorine electrode 3 passes through the elastic clamp 602 and the fixed base 601, so that it extends into the inner cavity of the beaker 2 and is immersed in the standard solution. The residual chlorine electrode 3 is locked and fixed by the locking bolt 603, thereby providing support for the residual chlorine electrode 3, enabling it to read stably, reducing human error, and effectively improving the calibration operation of the residual chlorine analyzer.
