Description

Technical Field

[0001] This utility model relates to the field of reducing sugar testing technology, and more specifically to an auxiliary device for reducing sugar determination. Background Technology

[0002] In the detection of reducing sugar content in granulated sugar, the sugar solution needs to be continuously added dropwise while maintaining a boil until the blue color just disappears. This process requires both continuous boiling and titration, resulting in a large amount of high-temperature steam at the mouth of the conical flask. Directly handling the titration by hand can cause burns, hindering the process and leading to inaccurate results. For example, Chinese Utility Model Patent CN206192966U discloses a titration device for detecting reducing sugars. It extends the length of the glass tip of the burette and fixes a splash guard below the valve to prevent burns from rising steam. However, because the shape of the protective guard is fixed, its protective effect is poor. Furthermore, the distance between the protective guard and the conical flask allows steam to continue rising along the edge of the guard, still posing a risk of burns. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: An auxiliary device for reducing sugar determination includes a box body.

Slide rails one and two are symmetrically fixed on both sides of the box body. Two sliders are symmetrically slidably connected to slide rails one and two, respectively. The sliders are limited by knobs connected to slide rails one and two. The sliders of slide rails one and two are fixedly connected to each other by moving rods one and two, respectively. Moving rods one and two are parallel to the width direction of the box body. Clamping components one and two are symmetrically fixedly connected to moving rods one and two. A burette is placed above the conical flask and clamped and fixed by clamping components one and two. Fixing components one and two for fixing the conical flask are symmetrically fixedly connected to moving rods one and two. Ventilation openings and exhaust fans are installed on both symmetrical sides of the box body.

A cross clamp is installed on the first support rod, and a universal clamp is also installed on the cross clamp. The second clamping assembly has the same structure as the first clamping assembly.

[0006] The first fixing component includes a telescopic rod, one end of which is fixedly connected to the first movable rod, and the other end is fixedly connected to an arc-shaped fixing block.

Slide rails 5 and 6 are symmetrically fixed on both sides of the box 1. Two sliders 7 are symmetrically slidably connected to slide rails 5 and 6. The sliders 7 are limited by knobs and can be adjusted and fixed on the slide rails as needed. The sliders 7 of the slide rail 2 6 are fixedly connected by moving rod 1 8 and moving rod 2 9 respectively. The moving rod 1 8 and moving rod 2 9 are parallel to the width direction of the box body 1. Clamping component 1 and clamping component 2 are symmetrically fixedly connected to the moving rod 1 8 and moving rod 2 9. A burette 10 is provided above the conical flask 4. The burette 10 is clamped and fixed by clamping component 1 and clamping component 2.

Ventilation openings 11 and exhaust fans 12 are respectively opened on the symmetrical sides of the box body 1. The ventilation openings 11 and exhaust fans 12 are installed in the length direction of the box body 1.

[0017] The first clamping assembly includes a support rod 13, which is vertically fixed to the first moving rod 8. A cross clamp 14 is installed on the first support rod 13, and a universal clamp 15 is also installed on the cross clamp 14. In this embodiment, the universal clamp 15 is a commercially available universal clamp 15, and its specific structure will not be described in detail here. The universal clamp 15 can be flexibly adjusted through the cross clamp 14, and thus the clamping position of the burette 10 can be flexibly adjusted according to actual needs. The second clamping assembly has the same structure as the first clamping assembly, and its structure will not be described in detail here.

[0018] The first fixing component includes a telescopic rod 16, one end of which is fixedly connected to the moving rod 8, and the other end is fixedly connected to an arc-shaped fixing block 17. The arc-shaped fixing block 17 engages with the neck of the conical bottle 4.

[0019] Furthermore, in order to further avoid burns to the operator from the hot air generated during the titration test, a conical baffle 21 is provided at the lower part of the burette 10 above the conical flask 4. The conical baffle 21 can block the generated hot air. The conical baffle 21 is made of transparent material, which makes it easy to observe the measurement process.

[0021] Work process First, slide slider 7 to the appropriate position using the knob. Then, fix conical flask 4 above electric furnace 2 using the fixing component. Next, adjust universal clamp 15 to the appropriate position using cross clamp 14, and fix burette 10 using universal clamp 15. Then, start exhaust fan 12 to begin testing. The hot air generated during the measurement process is discharged through exhaust fan 12. At the same time, due to the conical baffle 21, the hot air can be further blocked, thereby avoiding burns to the operator, ensuring the normal progress of the measurement, and ensuring the accuracy of the experimental results.
