Description

Technical Field

[0001] The present invention relates to the technical field of experimental equipment for demulsification degree testing, and in particular to a water bathtub device capable of eliminating bubbles on the inner wall. Background Art

[0002] During the determination of the demulsification degree of turbine oil, usually 40 ml of oil sample and 40 ml of distilled water are placed in a test tube, and stirred for 5 minutes at 54°C ± 1°C to form an emulsion. Subsequently, the time required for the separation of the emulsion (i.e., when the volume of the emulsion layer is not more than 3 ml) is measured. To ensure the constancy of the temperature during the experiment, a water bathtub is generally used to continuously keep the test tube warm. A heater is provided outside the water bathtub, and circulating hot water is supplied into the water bathtub to maintain the stability of the internal temperature.

[0003] However, it is found in actual operation that when the external heater supplies circulating hot water into the water bathtub, a large number of bubbles are easily generated on the inner wall of the water bathtub. These bubbles adhere to the inner wall, which not only affects the aesthetics of the experimental environment, but more importantly, interferes with the shooting quality of the external camera for the separation of the emulsion in the test tube, resulting in inaccurate experimental results or inability to read the results. This phenomenon is particularly significant in research that requires precise observation and recording of the emulsion separation process, bringing great inconvenience and technical challenges to researchers. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the bubbles adhering to the inner wall of the bathtub affect the shooting quality of the external camera for the separation of the emulsion in the test tube, resulting in inaccurate experimental results or inability to read the results.

However, these terms may change according to the intentions of those of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0034] Referring to Figure 1 and Figure 2 , this embodiment provides a water bathtub device capable of eliminating bubbles on the inner wall, including a test tube positioning plate 12 provided inside a water bathtub body 11 for supporting a demulsification test tube 13. The test tube positioning plate 12 is fixedly connected to the side wall of the water bathtub body 11 and is arranged close to the bottom, facilitating the positioning and placement of the test tube and ensuring that the samples in the test tube can be heated and observed under optimal conditions.

[0035] Fixing element 1, including a water bathtub body 11, which serves as the main container of the entire device for containing liquid. A plurality of water and gas outlets 21 are arranged inside it, and these water and gas outlets 21 are distributed at positions close to the bottom of the water bathtub body 11 and are connected to the energy supply element 3 through pipelines;

[0036] Defoaming element 2, which can eliminate bubbles; and

[0037] An energy supply element 3, a gear pump 38, a water heating device 31, a first one-way valve 35, an air pump 34, a second one-way valve 39, and a solenoid valve 36 are provided between the fixing element 1 and the defoaming element 2. These devices are all controlled by a control system to ensure that the water flow and air flow are accurately delivered according to preset conditions.

[0038] The input end of the water inlet pipe is also connected to the water return pipe 37. The water return pipe 37 is arranged inside the water bathtub body 11 near the top, and circulating water is used for heating to improve the heating and heat preservation efficiency.

[0039] A number of air outlet ports 21 are arranged inside the water bathtub body 11, and the air outlet ports 21 introduce gas into the inside of the water bathtub body 11 to generate bubbles.

[0040] When it is necessary to remove the tiny bubbles on the inner wall, air is introduced into the water pipe 22 through the air pump 34. A large flow of air is discharged from the air outlet ports 21, generating a large number of larger bubbles. These larger bubbles move upward from the bottom of the inner wall of the water bathtub body 11, thus generating a drag effect and a turbulence effect, carrying away the smaller bubbles on the inner wall of the water bathtub, so as to achieve the cleaning effect.

[0041] The test tube positioning plate 12 inside the water bathtub body 11 can support the demulsification test tube 13.

[0042] Refer to Figure 1 , the water bathtub device can not only efficiently heat the liquid and keep it at a constant temperature, but also effectively remove the bubbles on the inner wall, providing clear observation conditions for experimental operations. Especially through the design of the air outlet ports 21 in different directions, the all-round bubble removal function is realized, improving the accuracy and reliability of the experimental results.

[0043] The air outlet ports 21 are arranged on the side wall of the water pipe 22. The horizontal section of the water pipe 22 is arranged close to the bottom of the inner wall of the water bathtub body 11 and extends along the length direction of the water bathtub body 11. The air outlet ports 21 opened upward jet gas upward. These air outlet ports 21 are located at the top of the water pipe 22, and the gas jets upward through these openings, generating a large number of larger bubbles. These bubbles move upward from the bottom of the inner wall of the water bathtub body 11, carrying away the smaller bubbles on the inner wall of the water bathtub, so as to achieve the cleaning effect. The air outlet ports 21 opened on the side wall jet toward the inner wall of the water bathtub body 11. These air outlet ports 21 are located on the side of the water pipe 22 and jet gas toward the inner wall of the water bathtub body 11. This design helps to directly impact and remove the tiny bubbles attached to the inner wall of the water bathtub, further improving the cleaning efficiency.

[0044] The water pipe 22 located inside the water bathtub body 11 is arranged in an L shape. The end of the water pipe 22 at the bottom end of the inner wall of the water bathtub body 11 is also provided with air outlet ports 21. Its air outlet is for uniform bubble distribution, reducing the bubble cleaning dead angle, and improving the effective cleaning of the small bubbles attached to the water bathtub body 11. Its air outlet ports 21 are arranged as circular holes.

[0045] Refer to Figure 1 - Figure 2, The water bathtub device can not only efficiently heat the liquid and maintain a constant temperature, but also effectively remove the bubbles on the inner wall, providing clear observation conditions for experimental operations. In particular, through the combined design of the water conduit 32 and the gas conduit 33, the uniform mixing of water and gas is achieved, further improving the effect of bubble removal.

[0046] The energy supply element 3 includes a water heating device 31 provided on the side wall of the water bathtub body 11. The water outlet of the water heating device 31 is equipped with a water conduit 32 connected to the water gas pipe 22. The water conduit 32 is connected to the water gas pipe 22 to introduce the heated water into the water gas pipe 22.

[0047] The side wall of the water conduit 32 is equipped with a gas conduit 33 for mixing gas with water and introducing it into the water bathtub body 11. One end of the gas conduit 33 far from the water conduit 32 is equipped with an air pump 34 for delivering air into the gas conduit 33.

[0048] One end of the gas conduit 33 close to the water conduit 32 is equipped with a first one-way valve 35 to prevent the water flow from flowing back into the gas conduit 33. An electromagnetic valve 36 is installed between the air pump 34 and the first one-way valve 35 to control the gas flow.

[0049] The water inlet of the water heating device 31 is equipped with a return water pipe 37. The side wall of the return water pipe 37 is equipped with a gear pump 38 for driving the water flow. A second one-way valve 39 is installed at the water outlet position of the water heating device 31 to ensure that the water flow can only flow in one direction and prevent the heated hot water from flowing back into the water heating device 31.

[0050] Both the first one-way valve 35 and the second one-way valve 39 are mechanical structures to ensure the one-way flow of water and air, prevent the occurrence of backflow phenomena, and the return water pipe 37 is located inside the water bathtub body 11 and close to the top for circulating water heating.

[0051] When it is necessary to heat the liquid in the water bathtub body 11, the gear pump 38 drives the return water pipe 37 to send the water in the water bathtub body 11 into the water heating device 31. After heating, it flows into the water gas pipe 22 through the water conduit 32. At the same time, the control system can automatically turn on the air pump 34 according to the preset conditions, and introduce air into the water conduit 32 through the gas conduit 33, so that the gas and the heated water are fully mixed in the water conduit 32. The mixed water and gas are sprayed into the water bathtub body 11 through the water and gas outlet 21 on the water gas pipe 22. The large upwardly sprayed air bubbles can carry away the small bubbles at the bottom of the inner wall of the water bathtub, thus achieving a cleaning effect.

[0052] As an alternative embodiment, refer to Figure 3 , The difference between this embodiment and the above embodiments is that two shapes of water and gas outlets 21 will be provided.

[0053] When the water and gas outlet 21 is set as a slit-shaped hole, it can adjust the bubble size and the gas flow direction, which helps to better control the formation of bubbles and their rising paths. While the circular hole is simple and easy to process, and is suitable for generating relatively uniform bubbles.

[0054] When the water and gas outlet 21 is set as an array of circular holes, through the combination of multiple small holes, the total gas outflow area can be increased, and the gas flow rate can be improved. In addition, multiple small holes can distribute the gas more evenly, reducing the possibility of local bubble accumulation.

[0055]

[0056] From the above data, it can be seen that for a single circular hole: at the same gas flow rate, the gas outflow area of a single circular hole is limited, resulting in insufficient gas flow rate to effectively remove all bubbles, with a relatively large number of bubbles remaining on the inner wall and a low removal efficiency.

[0057] Array of circular holes: By increasing the number of holes, although the diameter of each hole is small, the overall gas outflow area increases significantly, improving the gas flow rate, thereby reducing the number of bubbles remaining on the inner wall and enhancing the removal efficiency.

[0058] Slit-shaped hole: The slit-shaped hole has a relatively large opening area, which can provide a higher gas flow rate at the same gas flow rate. At the same time, its directional jetting characteristic enables it to more effectively impact and remove the bubbles attached to the inner wall, significantly reducing the number of bubbles remaining on the inner wall and improving the removal efficiency.

[0059] Compared with a single circular hole, the array of circular holes increases the gas outflow area by increasing the number of holes, thereby enhancing the gas flow rate and the removal efficiency. The slit-shaped hole provides a higher gas flow rate and a more effective bubble removal effect under the same conditions through its larger opening area and directional jetting characteristic.

[0060] Therefore, when designing the water and gas outlet 21 of the water bathtub device, adopting a combination of an array of circular holes and a slit-shaped hole can significantly improve the bubble removal efficiency, ensure the cleanliness of the inner wall of the water bathtub, and provide clearer observation conditions for experimental operations. However, when using circular holes, with a gas pump 34 of 15 liters per minute, due to its relatively large power, it can also improve the bubble elimination efficiency. Therefore, in actual use, a suitable method can be selected according to the actual situation.

[0061] In an embodiment provided by the present application, referring to Figure 4 - Figure 8 , in this embodiment, an adjusting member 23 is provided at the upward jetting water and gas outlet 21.

[0062] The adjusting member 23 is rotatably arranged with the water and gas pipe 22, and its rotation is limited by the limit buckle 23a. When rotation is required, rotate the ring body 23b. Since both ends of the limit buckle 23a are provided with gentle slopes, the frictional force is relatively large during rotation. Only when the rotational force is greater than the frictional force can the position of the water and gas hole 23c be adjusted. Moreover, when the water and gas pipe 22 is working for ventilation and water supply, the pressure is relatively large. Therefore, the air flow and water flow will flow into the cavity 23d, and the pressure in the cavity 23d will drive the piston 23e in the cavity 23d to move. The moving piston 23e will drive the sphere 23f to be pressed between the two limit buckles 23a for limit fixation. Since the slope is provided between the two limit buckles 23a, the sphere 23f will always be in the middle position without skewing, and can be well positioned to prevent the problem of skewing between the water and gas hole 23c and the water and gas outlet 21.

[0063] It should be noted that when there is no air and water flow in the cavity 23d, the piston 23e can effectively drive the sphere 23f to move back by the self-elastic force of the telescopic spring, so that the positioning friction is reduced and the adjustment of the water and gas outlet 21 is more convenient.

[0064] When the ring body 23b drives the water and gas hole 23c to rotate, since the aperture of the water and gas hole 23c is inconsistent, the water flow rate of the water and gas hole 23c can be adjusted by adjusting the aperture.

[0065] Finally, it should be pointed out that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
