Description

Technical Field

[0001] This utility model relates to the field of petroleum viscosity testing technology, and in particular to a stirring-type petroleum viscosity meter. Background Technology

[0002] In the industrial processes of oil extraction, refining, and transportation, oil viscosity is a core indicator for assessing oil quality, determining processing techniques, and ensuring safe transportation. Accurate measurement of oil viscosity is of great significance for the efficient operation of industrial production.

[0003] However, most petroleum viscosity testing devices currently on the market have significant design flaws. As a typical temperature-sensitive fluid, petroleum's viscosity varies significantly with temperature. Most existing viscosity meters do not adequately consider the impact of ambient temperature and the material's own temperature fluctuations on the test results. This makes it difficult to meet the stringent accuracy requirements of industrial production. Therefore, a stirring-type petroleum viscosity meter is urgently needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stirring-type petroleum viscosity meter. Its advantages include: precise water bath heating (capable of heating petroleum to 40°C) ensures uniform heating of the petroleum; the adjustable control box height and stable container positioning structure ensure reliable testing conditions, thereby improving the accuracy, operational flexibility, and safety of petroleum viscosity measurement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stirring-type petroleum viscosity meter includes a control box, a support rod inserted into the bottom of the control box, a base fixedly connected to the bottom of the support rod, a fixing ring plate fixedly connected to the outer wall of the base, and a water bath assembly for heating petroleum fixedly connected to the inner circumference of the fixing ring plate. A motor is fixedly connected to the bottom of the control box, a rotating rod is fixedly connected to the output end of the motor, a rotor is fixedly connected to the outer circumference of the rotating rod, the rotor is located inside the holding cup, and the holding cup is placed inside the constant temperature cylinder.

[0006] The above technical solution utilizes the resistance encountered by the rotor during rotation to provide feedback on the viscosity of the oil. At the same time, the water bath component regulates the temperature of the oil in the container, laying the foundation for viscosity detection from both structural and functional perspectives.

[0007] Preferably, a screw is threaded to one side of the outer wall of the control box, and a knob is fixedly connected to one end of the screw. The knob is located outside the control box, and the end of the screw away from the knob abuts against the outer circumferential wall of the support rod. A positioning cylinder is fixedly connected inside the control box, and the support rod passes through the inside of the positioning cylinder. An annular pad is fixedly connected to the inner circumferential wall of the positioning cylinder, and the support rod abuts against the inner circumferential wall of the annular pad through the screw.

[0008] The above technical solutions allow for convenient adjustment of the control box height to suit different working conditions while ensuring structural stability after adjustment.

[0009] Preferably, a limiting plate is fixedly connected to the top of the support rod, and the diameter of the limiting plate is larger than the diameter of the support rod.

[0010] The above technical solutions prevent the control box from slipping and being damaged due to operational errors, thus improving the safety of the device operation.

[0011] Preferably, the outer circumferential wall of the rotating rod has a groove, and the oil contained in the cup is submerged in the groove.

[0012] The above technical solutions ensure that the rotor is fully immersed in the oil, avoiding deviations in the test data due to insufficient rotor immersion depth, and further guaranteeing the accuracy of viscosity measurement.

[0013] Preferably, the water bath assembly includes a thermostatic cylinder fixedly connected to the inner circumference of the fixed ring plate, the thermostatic cylinder containing clean water, a partition fixedly connected to the inner circumference of the thermostatic cylinder, a heating coil for heating the water being disposed above the partition, a temperature sensor fixedly connected to the inner circumference of the thermostatic cylinder, and both the heating coil and the temperature sensor being electrically connected to the control panel.

[0014] The above technical solutions enable precise water temperature control, providing a uniform and stable heating environment for petroleum.

[0015] Preferably, a support is fixedly connected to the inner circumference of the thermostatic cylinder, the support has a concave cross-section, and the bottom end of the thermostatic cylinder is inserted into the support.

[0016] The above technical solutions prevent the container from shifting or tipping over inside the constant temperature cylinder, and especially enhance the stability of the container when the rotor is rotating, reducing the interference of structural shaking on the detection.

[0017] Preferably, a limiting ring frame is fixedly connected to the inner circumference of the thermostatic cylinder, and the thermostatic cylinder passes through the middle of the limiting ring frame.

[0018] Through the above technical solutions, the limiting ring frame can limit the cup from the middle, and together with the support of the bearing seat to the bottom, a double positioning structure is formed to ensure that the cup remains in a centered and stable state during the testing process, thereby improving the reliability of the testing conditions.

[0019] The beneficial effects of this utility model are as follows: A stirring-type petroleum viscosity analyzer ensures the reliability of test results through precise water bath heating and a stable structural design. In the water bath assembly, the heating coil and temperature sensor, together with the control panel, form a closed-loop control that can accurately heat the petroleum to the required 40°C for testing. The water bath method ensures uniform heating of the petroleum, completely avoiding interference from local temperature deviations in viscosity testing. At the same time, the concave support seat and limiting ring frame inside the constant temperature cylinder work together to provide stable support and positioning for the container, preventing the container from shaking when the rotor rotates. This improves the testing accuracy from both temperature control and structural stability perspectives.

[0020] A stirring-type petroleum viscosity analyzer, through its adjustable structural design, meets the testing needs of different scenarios. Specifically, the screw and knob on one side of the control box, in conjunction with the positioning cylinder and annular pad, enable the vertical height adjustment of the control box along the support rod. This allows for flexible adaptation to containers of different heights or adjustment of the rotor's immersion depth in petroleum. Furthermore, the groove on the outer wall of the rotor provides a clear reference for observing the liquid level, ensuring that the rotor is fully immersed in the petroleum and avoiding testing errors caused by insufficient immersion depth. This makes the operation more convenient and has wider adaptability. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0027] Reference Figures 1-4 A stirring-type petroleum viscosity meter includes a control box 1, a support rod 7 inserted into the bottom of the control box 1, a base 8 fixedly connected to the bottom of the support rod 7, a fixing ring plate 9 fixedly connected to the outer wall of the base 8, and a water bath assembly for heating petroleum fixedly connected to the inner circumference of the fixing ring plate 9. A motor 3 is fixedly connected to the bottom of the control box 1. A rotating rod 4 is fixedly connected to the output end of the motor 3. A rotor 16 is fixedly connected to the outer circumference of the rotating rod 4. The rotor 16 is located inside the holding cup 5. The holding cup 5 is placed inside the constant temperature cylinder 6. The motor 3 at the bottom of the control box 1 drives the rotating rod 4 and the rotor 16 to rotate. The rotor 16 extends into the oil in the holding cup 5. The resistance encountered by the rotor 16 when rotating is used to provide feedback on the oil viscosity. At the same time, the water bath assembly regulates the temperature of the oil in the holding cup 5. This lays the foundation for viscosity detection from both structural and functional aspects.

[0028] Furthermore, a screw 13 is threadedly connected to one side of the outer wall of the control box 1. A knob 14 is fixedly connected to one end of the screw 13. The knob 14 is located outside the control box 1. The end of the screw 13 away from the knob 14 is pressed against the outer circumferential wall of the support rod 7. A positioning cylinder 11 is fixedly connected inside the control box 1. The support rod 7 passes through the inside of the positioning cylinder 11. An annular pad 12 is fixedly connected to the inner circumferential wall of the positioning cylinder 11. The support rod 7 is pressed against the inner circumferential wall of the annular pad 12 by the screw 13. Rotating the knob 14 can drive the screw 13 to rotate, so that the screw 13 moves away from or presses against the support rod 7. With the guiding effect of the positioning cylinder 11 on the support rod 7 and the enhanced friction of the annular pad 12, the height of the control box 1 can be easily adjusted to adapt to different working conditions, and the structural stability after adjustment can be guaranteed.

[0029] Furthermore, a limiting plate 10 is fixedly connected to the top of the support rod 7. The diameter of the limiting plate 10 is larger than the diameter of the support rod 7. This effectively prevents the control box 1 from detaching from the support rod 7 when it is adjusted upward along the support rod 7, thus avoiding damage to the control box 1 due to operational errors and improving the safety of the device operation.

[0030] Furthermore, the outer circumferential wall of the rotating rod 4 is provided with a groove 17. The oil contained in the holding cup 5 is submerged in the groove 17, providing a clear reference for the oil level. The groove 17 on the rotating rod 4 can serve as a liquid level reference, ensuring that the oil in the holding cup 5 is submerged in the groove 17, and ensuring that the rotor 16 is completely immersed in the oil. This avoids deviations in the detection data due to insufficient immersion depth of the rotor 16, further ensuring the accuracy of viscosity measurement.

[0031] Furthermore, the water bath assembly includes a thermostatic cylinder 6 fixedly connected to the inner wall of the fixed ring plate 9. The thermostatic cylinder 6 contains clean water. A partition 21 is fixedly connected to the inner wall of the thermostatic cylinder 6. A heating coil 20 for heating the water is installed above the partition 21. A temperature sensor 15 is fixedly connected to the inner wall of the thermostatic cylinder 6. The heating coil 20 and the temperature sensor 15 are electrically connected to the control panel 2. The heating coil 20 in the thermostatic cylinder 6 heats the clean water. The partition 21 can separate the heating area from the area where the container cup 5 is placed. The temperature sensor 15 monitors the water temperature in real time and transmits the data to the control panel 2. The control panel 2 adjusts the working state of the heating coil 20 according to the data to achieve precise water temperature control and provide a uniform and stable heating environment for the petroleum.

[0032] Furthermore, a support seat 19 is fixedly connected to the inner circumference of the constant temperature cylinder 6. The cross-section of the support seat 19 is concave. The bottom end of the constant temperature cylinder 6 is inserted into the inside of the support seat 19. The concave structure of the support seat 19 can support and position the bottom end of the container 5, preventing the container 5 from shifting or tipping over inside the constant temperature cylinder 6. In particular, it can enhance the stability of the container 5 when the rotor 16 rotates, and reduce the interference of structural shaking on the detection.

[0033] Furthermore, a limiting ring frame 18 is fixedly connected to the inner circumference of the constant temperature cylinder 6. The constant temperature cylinder 6 passes through the middle of the limiting ring frame 18, which can limit the container 5 from the middle. Together with the support of the bearing seat 19 for the bottom, a double positioning structure is formed to ensure that the container 5 always remains in a central and stable state during the testing process, thereby improving the reliability of the testing conditions.

[0034] Working principle: In use, the oil to be tested is first loaded into the holding cup 5, and the holding cup 5 is placed in the constant temperature cylinder 6 and supported by the support seat 19. The holding cup 5 is limited by the limiting ring frame 18 to ensure that the holding cup 5 can remain stable during the subsequent rotation of the rotor 16 and will not shake and affect the test results. At the same time, the center of the support seat 19 has a through hole to facilitate the water bath component to fully heat the oil in the water bath. Then, the control box 1 can adjust the height up and down along the support rod 7 by the cooperation of the screw 13 and the knob 14. The positioning cylinder 11 and the annular pad 12 ensure the stability during adjustment until the rotor 16 at the bottom of the rotating rod 4 extends into the oil in the holding cup 5 and the oil covers the groove 17 on the rotating rod 4. The groove 17 is set to make the oil level position more clearly visible and ensure that the rotor 16 is completely immersed in the oil, providing reliable conditions for subsequent testing. After the height of rotor 16 is adjusted, the device is started via control panel 2, and the water bath assembly begins to work. The heating coil 20 in the thermostatic cylinder 6 heats the internal water. Temperature sensor 15 monitors the water temperature in real time and feeds the data back to control panel 2, achieving precise control of the water temperature and heating the oil to 40℃. This water bath heating method ensures uniform heating of the oil, avoids local temperature deviations affecting viscosity detection accuracy, and effectively improves detection accuracy. Then, motor 3 starts, driving the rotating rod 4 and rotor 16 to rotate. The resistance experienced by rotor 16 when rotating in the oil is directly related to the oil viscosity. By detecting and analyzing parameters such as the load of motor 3 through relevant components in control box 1, the viscosity data of the oil can be obtained, meeting people's needs for accurate detection of oil viscosity.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
