Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and in particular to a viscosity testing device for defoamers. Background Technology

[0002] Defoamers are mostly non-Newtonian fluids, and their viscosity significantly affects storage stability, defoaming efficiency, and the accuracy of dosage. Traditional rotational viscometers can only provide static viscosity values ​​at a single shear rate, failing to reflect the rheological behavior of the product under actual application conditions. Furthermore, they are susceptible to temperature fluctuations, bubble interference, and human error, resulting in limited data guidance value. Therefore, a viscosity detection device for defoamers needs to be designed.

[0003] To this end, patent CN217404059U discloses a digital display viscosity testing device for detecting the viscosity of food additives, belonging to the field of measuring instruments. The key technical points of the device include a base, a guide column vertically arranged on the base, a detection host slidably connected to the guide column, a rotor connected to the bottom of the detection host, a positioning line set on the rotor, a positioning block slidably connected to the guide column below the detection host, an extension strip for aligning with the liquid surface of the liquid set at the bottom of the positioning block, the distance from the top of the positioning block to the extension strip being the same as the distance from the bottom of the detection host to the positioning line, and a fixing component for fixing the positioning block set on the positioning block. This invention has the advantages of being convenient in aligning the positioning line and having high accuracy.

[0004] While the digital viscosity testing device for detecting the viscosity of food additives mentioned above is easy to align during use, the rotor is prone to measurement inaccuracies after long-term use, and it is inconvenient to replace different rotors for different samples. Therefore, it is necessary to design a viscosity testing device for defoamers. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 The present invention provides a viscosity testing device for defoamers, including a base 1.

[0031] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 A lifting structure 2 is fixed to one side of the top of the base 1.

The lifting structure 2 also includes a servo motor 25 fixedly installed on the top of the lifting seat 21. The guide rods 23 and the lifting block 24 are slidably connected. Both ends of the guide rods 23 are fixedly connected to the inner wall of the lifting seat 21. The top of the lead screw 22 extends to the outside of the lifting seat 21 and is fixedly connected to the output end of the servo motor 25. A support plate 3 is fixed to one side of the top of the lifting structure 2. A detection component 4 is fixed to the top of the support plate 3. The detection component 4 includes a housing 41 fixed to the top of the support plate 3. A drive motor 42 is fixedly installed at the bottom of the housing 41. A coupling 43 is fixedly installed at the output end of the drive motor 42.

[0032] When an external power supply is connected, the servo motor 25 is started. The start of the servo motor 25 will drive the lead screw 22 to rotate. When the lead screw 22 rotates, it will drive the lifting block 24 to move up and down along the guide rod 23 inside the lifting seat 21. When the lifting block 24 moves, it can drive the detection component 4 and the viscosity measurement component 6 to move up and down through the support plate 3. It can drive the viscosity measurement component 6 to descend, so that the rotor 61 can be inserted into the sample cup 8, which is convenient for the rotor 61 to detect the viscosity of the defoamer. The drive motor 42 is started. The drive motor 42 can drive the viscosity measurement component 6 to rotate through the coupling 43 and the quick-release structure 5. By controlling the speed of the drive motor 42, the speed of the viscosity measurement component 6 can be controlled, which is convenient for detecting the viscosity of the defoamer under different shear rates.

[0033] Reference Figures 2-4 The bottom of the detection component 4 is fixed with a quick-release structure 5. The quick-release structure 5 includes a connecting seat 51 fixed to the bottom of the detection component 4. The bottom of the connecting seat 51 is provided with a mounting shaft 52. Both sides of the mounting shaft 52 are fixed with ejector springs 53. One end of each ejector spring 53 is fixed with a locking block 54. The interior of the connecting seat 51 on both sides of the mounting shaft 52 is provided with a reserved groove 57. The interior of each reserved groove 57 is provided with a pressure shaft 56. The exterior of each pressure shaft 56 is provided with a reset spring 58. One end of the pressure shaft 56 is fixed with a top plate 59. The other end of the pressure shaft 56 extends to the exterior of the connecting seat 51 and is fixed with a pressing plate 55. One end of each locking block 54 extends into the interior of the reserved groove 57. The locking blocks 54 are symmetrically distributed on both sides of the mounting shaft 52. The central axis of the locking blocks 54 is collinear with the central axis of the pressure shaft 56. One end of each reset spring 58 is fixedly connected to one side of the top plate 59. The other end of each reset spring 58 is fixedly connected to the inner wall of the connecting seat 51. A viscosity measuring component 6 is fixed to the bottom end of the mounting shaft 52. The viscosity measuring component 6 includes a connecting shaft 62 fixed to the bottom end of the mounting shaft 52. A rotor 61 is fixed to the bottom end of the connecting shaft 62. A liquid level marking ring 63 is fixed to the outer wall of the bottom of the connecting shaft 62.

[0034] Manually press the locking block 54. When the locking block 54 is squeezed, it will compress the ejector spring 53 and retract it into the mounting shaft 52. Then, align the mounting shaft 52 with the connecting seat 51 and insert the mounting shaft 52 upward into the circular groove at the bottom of the connecting seat 51. When the locking block 54 reaches the position of the reserved groove 57, the ejector spring 53 pushes the locking block 54 outward, so that the locking block 54 springs into the reserved groove 57 and locks it. When it needs to be replaced, press the pressing plates 55 on both sides at the same time. The pressing plates 55 squeeze the locking block 54 inward through the pressing shaft 56 and the top plate 59, so that the locking block 54 is removed from the reserved groove 57. Then, pull the mounting shaft 52 downward, so that the mounting shaft 52 and the viscosity measuring component 6 can be removed as a whole, which is convenient for replacing the viscosity measuring component 6. When using, a damper can be added inside the ejector spring 53 to prevent the ejector spring 53 from deforming during use and to ensure that the ejector spring 53 will not deviate when it is extended and retracted.

[0035] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 A constant temperature structure 7 is fixed to one side of the top of the base 1. The constant temperature structure 7 includes a constant temperature chamber 71 fixed to one side of the top of the base 1. A heating chamber 72 is fixed to the inner wall of the constant temperature chamber 71. A heating wire 75 is fixedly installed inside the heating chamber 72. A temperature sensor 74 is fixed to the inner wall of the bottom of the constant temperature chamber 71. A bracket 73 is fixedly installed at the bottom of the temperature sensor 74. A microcontroller is installed inside the bracket 73. The output end of the bracket 73 and the input end of the heating wire 75 are electrically connected through the microcontroller. A sample cup 8 is set on the top of the constant temperature structure 7.

[0036] An external power supply and a temperature sensor 74 monitor the temperature around the sample cup 8 in real time and transmit the data to a microcontroller inside the support 73. The microcontroller compares the measured value with the set value. If the temperature is lower than the set value, the microcontroller controls the heating wire 75 to be energized and heated. When the heating wire 75 is heating, it will heat the constant temperature chamber 71 through the heating chamber 72. The constant temperature chamber 71 will heat the water inside, which can heat the sample cup 8. If the temperature reaches the set value, the heating will stop. This cycle forms a precise closed-loop temperature control system, which controls the sample temperature fluctuation within a very small range.
