[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Example

[0033] like Figures 1 to 11 As shown, a chemical impurity detection device includes a mounting base 1, a mounting tube 2, and a measuring component. The measuring component includes a probe 53, an elastic coil 51, and a microprocessor 5. The probe 53 and the microprocessor 5 are connected via the elastic coil 51, which can stretch and contract for convenient portable testing. A third mounting groove 16 is provided at the upper end of the mounting base 1, and the microprocessor 5 is disposed in the third mounting groove 16. A lead wire groove 17 is provided on the outer side of the third mounting groove 16. The elastic coil 51 has vertical lines on both sides and passes through the lead wire groove 17. The probe 53 is detachably connected to the mounting tube 2. The mounting tube 2 is mounted on the mounting base 1 and is hollow inside. A first mounting groove 21 is provided on the upper side of the mounting tube 2, and the elastic coil 51 is disposed in the first mounting groove 21. That is, the curved section of the elastic coil 51 is housed and protected inside the mounting tube 2, preventing it from being directly exposed to the raw liquid and subjected to environmental influences such as high temperatures.

[0034] In this invention, the testing device employs a portable viscosity measuring instrument from the prior art, such as the NDV-700 viscometer or the VL7-100B portable viscometer, which can perform instantaneous measurements by inserting it into the fluid. The sensor portion of this testing device is a solid structure without any moving parts, namely the probe 53, and is connected to a handheld microprocessor 5 with a display screen via an elastic coil 51.

[0035] Working principle:

[0036] The sensor (probe 53) has a vibrating hammer at its end, connected by a rod-shaped bearing, which generates vibrations at a standard frequency. During vibration, the movable part of the sensor shears the liquid being measured. Due to the different viscosities of the liquids, the drag force on this part varies, resulting in different energy losses. Thus, the energy lost during each vibration is measured by the sensing circuit and displayed on the microprocessor's screen. The viscosity value of the liquid can be obtained from this energy loss.

[0037] The Influence of Impurities on Viscosity: Impurities in chemical feedstock 81 (such as solid particles, suspended matter, and polymers) increase the internal friction of the fluid, leading to increased viscosity. Generally, the higher the impurity content, the greater the fluid viscosity. A mathematical model relating fluid viscosity and impurity content can be established using experimental or empirical data. For example, for a specific chemical feedstock 81, a 1% increase in impurity content may lead to a 5% increase in viscosity (the exact relationship needs to be determined experimentally). Indirect Estimation of Impurity Content: By measuring the fluid's viscosity and combining it with known mathematical models, the impurity content can be indirectly estimated.

[0038] This invention provides an impurity detection device for chemical testing, which can be used for both fixed and handheld sampling. It can be used flexibly according to specific needs and application scenarios, and has high versatility.

[0039] In this invention, the mounting base 1 secures the probe 53 and the microprocessor 5 of the detection device, while also housing the elastic coil 51. This prevents the elastic coil 51 from being exposed to high temperatures for extended periods. Furthermore, the microprocessor 5 is stored away, ensuring the lifespan of the detection device. When handheld operation is required, simply remove the probe 53 and the microprocessor 5 separately to complete the handheld detection operation. The overall structure is simple and the operation is convenient.

[0040] like Figures 1 to 11 As shown, in this invention, a first groove 14 is vertically formed inside the mounting base 1, and the mounting tube 2 is slidably disposed in the first groove 14. A slider 3 is slidably disposed on the inner wall of the mounting tube 2. The slider 3 is cylindrical, and a guide block 31 is disposed on one side of the slider 3. The guide block 31 slides close to the inner wall of the first mounting groove 21, and a sliding rod 32 is disposed on the guide block 31. A first mounting block 13 is disposed above the first groove 14, and the sliding rod 32 is slidably disposed inside the first mounting block 13. A retaining ring 33 is disposed at the end of the sliding rod 32. With this structure, the installation height of the mounting tube 2 and its extension relative to the mounting base 1 can be adjusted, thereby indirectly adjusting the installation position of the probe 53, so that it can be used to detect chemical raw materials 81 at different liquid levels.

[0041] Furthermore, a positioning tube 22 is provided in the middle of the mounting tube 2. The mounting tube 2 and the positioning tube 22 are perpendicular to each other and form a T-shape. A second mounting groove 23 is provided on one side of the positioning tube 22. A second mounting block 12 is provided below the first sliding groove 14. Both the second mounting block 12 and the first mounting block 13 are horizontally arranged. A second sliding groove 15 is provided laterally inside the mounting base 1 and the second mounting block 12. The second sliding groove 15 and the first sliding groove 14 are perpendicular to each other and communicate with each other. The positioning tube 22 is slidably arranged in the second sliding groove 15. By limiting each other through the first sliding groove 14 and the second sliding groove 15, it is ensured that the mounting tube 2 can be accurately guided and slid.

[0042] Furthermore, a slider 3 is slidably mounted on the inner wall of the positioning tube 22, and a guide block 31 is provided on one side of the slider 3. The guide block 31 slides close to the inner wall of the second mounting groove 23. A slide rod 32 is provided on the guide block 31, and the slide rod 32 is slidably mounted inside the second mounting block 12. A retaining ring 33 is provided at the end of the slide rod 32. This structure, utilizing the mounting tube 2, the positioning tube 22, and the slider 3, ensures that the mounting tube 2 can stably achieve lifting and lateral sliding adjustment.

[0043] Furthermore, the first mounting block 13 is provided with a first sliding hole 131 inside, and the sliding rod 32 on the mounting tube 2 is slidably disposed in the first sliding hole 131; the first mounting block 13 is provided with a first threaded hole 132 communicating with the first sliding hole 131, and a first locking screw 7 is disposed in the first threaded hole 132.

[0044] Furthermore, the second mounting block 12 is provided with a second sliding hole 121 that communicates with the second sliding groove 15, and the sliding rod 32 on the positioning tube 22 is slidably disposed in the second sliding hole 121; the second mounting block 12 is provided with a second threaded hole 122 that communicates with the second sliding hole 121, and a second locking screw 6 is disposed in the second threaded hole 122.

[0045] First, adjust the lateral position of the mounting tube 2. Move the mounting tube 2 laterally and adjust its lateral position. After the lateral position is adjusted, use the second locking screw 6 to tighten the slide rod 32 to fix it, ensuring that the mounting tube 2 cannot move laterally. Then, prepare to adjust the height position of the mounting tube 2.

[0046] Then, adjust the height of the mounting tube 2 by raising or lowering it. Once the height adjustment is complete, use the first locking screw 7 to tighten the slide rod 32 to secure it, ensuring that the mounting tube 2 cannot be raised or lowered. This adjustable structure is simple in design, easy to install, and convenient to operate.

[0047] Furthermore, a handle 52 is provided at the upper end of the probe 53. The handle 52 is a stepped cylinder, and a positioning cylinder 4 is provided on the outer side of the handle 52. The positioning cylinder 4 has a stepped hole 41 inside, and the handle 52 is placed in the stepped hole 41. A mounting cylinder 42 is provided on one side of the positioning cylinder 4, and the mounting cylinder 42 is detachably connected to the mounting tube 2. With this structure, the probe 53 is easy and quick to install. If it is necessary to remove the probe 53, simply lift the probe 53 to detach it from the positioning cylinder 4.

[0048] Furthermore, a connecting plate 11 is provided on the bottom side of the mounting base 1, and a plurality of connecting holes 111 are provided on the connecting plate 11. The connecting plate 11 can be connected to the side wall of the raw liquid tank 8.

[0049] like Figure 4As shown, the entire device is installed on the side wall of the raw liquid tank 8 for fixed measurement. The mounting tube 2 and probe 53 extend laterally into the upper side of the raw liquid 81, with the bottom end of probe 53 extending into the raw liquid 81 for detection. The mounting tube 2 protects the elastic coil 51, the positioning cylinder 4 protects the handle 52, and the mounting base 1 protects the microprocessor 5. For portable testing, simply lift the probe 53, remove the elastic coil 51, and detach the microprocessor 5 from the mounting base 1.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
