[0002] At present, when two-phase liquid is in a container, it is necessary to know the interface between the two liquid phases. If the two liquid phases have different observation characteristics and are not miscible, it is relatively easy to know the interface between the two liquid phases by observation. However, when the two liquid phases have the same observation characteristics, it is impossible to know the interface between the two liquid phases by observation. When the container is in a special environment such as high temperature and high pressure, the container is opaque and closed, so it is impossible to use an intuitive method to know the interface between the two liquid phases. Therefore, it is necessary to make a device that can calibrate the liquid phase interface. Summary of the invention

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] The liquid phase interface automatic calibration device of the present invention and the device, as Figure 1 As shown, it includes a conductive rod shell 2 for immersion in liquid, such as Figure 2 As shown, the conductive rod shell 2 is formed with array-arranged vias 3, such as Figures 2 to 4 As shown, a conductive needle 4 for connecting the conductive rod shell 2 through liquid is provided in the via hole 3, and the conductive needle 4 is insulated from the corresponding via hole 3. Figure 1 and Figure 3 As shown, an information collection module 5 is provided in the conductive rod shell 2 , and the information collection module 5 is electrically connected to the conductive needle 4 . The liquid phase interface automatic calibration device of the present invention also includes an information processing module 6 , and the information collection module 5 is signal-connected to the information processing module 6 .

[0023] Furthermore, if Figure 1 As shown, the information processing module 6 is connected to the data output interface 7, so the information processing module 6 can be connected to the external automation equipment through the data output interface 7, so that the external automation equipment can know the position of the liquid phase interface 11, and the external automation equipment can perform corresponding actions according to the position of the liquid phase interface 11.

[0024] Furthermore, if Figure 1 As shown, the liquid phase interface automatic calibration device of the present invention also includes an electrical box 8 for being arranged on the liquid surface. The information processing module 6 is arranged in the electrical box 8. The electrical box 8 protects the information processing module 6. The data output interface 7 is arranged on the electrical box 8, so it is convenient for the data output interface 7 to connect the data line.

[0025] Furthermore, if Figure 1 As shown, a power supply 1 is provided in the electrical box 8, and the power supply 1 outputs a safe voltage. The power supply 1 is electrically connected to the conductive rod shell 2 and the conductive needle 4. That is, the power supply 1 is used to form a direct current from the liquid at the corresponding position of the conductive needle 4 to the conductive rod shell 2, avoiding the need to connect an external power supply.

[0026] The method for using the liquid phase interface automatic calibration device of the present invention is as follows: Figure 1As shown, the following steps are included: Step S1, immersing the conductive rod shell 2 into the liquid (including liquid phase A and liquid phase B) in the liquid container 10, specifically, the conductive needles 4 are arranged in an array along the up and down direction, and when the conductive needles 4 are arranged in an array along the extension direction of the conductive rod shell 2, the conductive rod shell 2 is perpendicular to the horizontal plane. Step S2, the conductive needles 4 and the conductive rod shell 2 are electrically connected through the liquid at the corresponding position of the conductive needles 4. Specifically, since the distance between the conductive needles 4 and the edge of the corresponding via 3 is the shortest, the current actually mainly flows through the liquid between the conductive needles 4 and the edge of the corresponding via 3; if the power supply 1 is not provided, the liquid phase interface automatic calibration device of the present invention needs to be connected to an external power supply. In step S3, each conductive needle 4 is paired with the positive and negative electrodes of the corresponding via 3 to collect the charge information of the liquid at the corresponding position. The charge information is transmitted to the information collection module 5. The information collection module 5 transmits the charge information package to the information processing module 6. The information processing module 6 automatically analyzes and processes the parameter data of the charge information package provided by the information collection module 5 to determine the position of the liquid phase interface. The information processing module 6 automatically analyzes and processes the liquid phase interface parameter data obtained, thereby realizing automatic calibration of the interface between the liquid phases. The above parameter data can be output through the data output interface 7.

[0027] Step S3 includes: Step S31, when the liquid charge information of the corresponding positions of the upper and lower adjacent conductive needles 4 is consistent, the information processing module 6 determines that the corresponding positions of the upper and lower adjacent conductive needles 4 are the same liquid phase, and when the liquid charge information of the corresponding positions of the upper and lower adjacent conductive needles 4 is different, the information processing module 6 determines that the corresponding positions of the upper and lower adjacent conductive needles 4 are different liquid phases, so the interface between different liquid phases is located between the upper and lower adjacent conductive needles 4; since the position of each conductive needle 4 on the conductive rod shell 2 is known, and the relative height position of the conductive rod shell 2 and the liquid container 10 is also known, the height position of the interface between the liquid phases relative to the liquid container 10 can be known. Reducing the spacing of the conductive needles 4 can improve the accuracy of detecting the interface position between the liquid phases.

[0028] According to the above method, combined with Figure 5 As shown in the circuit diagram, more specifically, the information collection module 5 only connects one conductive needle 4 at a time, that is, each time only the liquid between the conductive needle 4 and the edge of the corresponding via 3 is energized, and the information collection module 5 connects the conductive needle 4 to the power supply 1 in turn, and the liquid phase resistance of the corresponding position of each conductive needle 4 can be obtained in turn. When the liquid phase resistance changes, Figure 5 The voltage across the current limiting resistor in the circuit changes accordingly, and the information processing module 6 specifically determines the change of the liquid phase according to the change of the voltage value, that is, by measuring the voltage across the current limiting resistor, the charge information of the liquid between the conductive needle 4 and the edge of the corresponding via 3 is directly obtained. The current limiting resistor is connected in series between the negative electrode of the power supply 1 and the conductive rod shell 2.

[0029] As can be seen from the above, the automatic calibration device for the liquid phase interface of the present invention is a non-observational detection device for the interface between liquid phases, so the conductive rod shell 2 can be set in a closed liquid container 10 for use, and the automatic calibration device for the liquid phase interface of the present invention can automatically calibrate the interface between two liquid phases with the same observation characteristics.

[0030] Furthermore, if Figure 1 As shown, the bottom of the electric box 8 is fixedly connected to the upper part of the conductive rod shell 2, so that the electric box 8 and the conductive rod shell 2 can be combined into a whole, making the liquid phase interface automatic calibration device easy to carry.

[0031] Furthermore, if Figure 1 and Figure 2 As shown, the bottom of the electric box 8 is connected to the upper part of the conductive rod shell 2 through the flange structure 9, and the upper end of the conductive rod shell 2 is connected to the inner cavity of the electric box 8. Specifically, the conductive rod shell 2 is a hollow structure, and the lower end of the conductive rod shell 2 is closed, while the upper end of the conductive rod shell 2 is provided with an outlet, and a threading hole is formed at the bottom of the electric box 8, and the threading hole is connected to the above-mentioned outlet. A lower flange is welded to the outside of the upper end of the conductive rod shell 2, and an upper flange is welded to the bottom of the electric box 8. The upper flange and the lower flange are fixedly connected by bolts; by providing the flange structure 9, it is convenient to install and connect the conductive rod shell 2 and the electric box 8.

[0032] Furthermore, the conductive rod shell 2 is cylindrical, that is, the outer shape of the conductive rod shell 2 is cylindrical, and the conductive rod shell 2 has a hollow structure, so the conductive rod shell 2 can be made of a round tube, which is conducive to easy material acquisition of the conductive rod shell 2. The sealing plate is welded to the lower end of the round tube to close the lower end of the round tube. The conductive rod shell 2 can be made of metals such as copper, stainless steel or aluminum.

[0033] Furthermore, if Figure 1 and Figure 4 As shown, the conductive needle 4 protrudes outward from the conductive rod shell 2, which is beneficial to increase the contact area between the conductive needle 4 and the liquid, and is beneficial to a good conductive connection between the conductive needle 4 and the liquid.

[0034] Furthermore, if Figure 4 As shown, an insulating sealing ring 31 is provided between the conductive needle 4 and the corresponding via hole 3. The insulating sealing ring 31 can be made of fluororubber, which has good chemical stability. The outer ring of the insulating sealing ring 31 contacts the edge of the via hole 3, and the conductive needle 4 passes through the insulating sealing ring 31, so that the insulating sealing ring 31 plays a sealing and insulating role.

[0035] like Figure 4 As shown, the outer end of the conductive needle 4 protrudes from the conductive rod housing 2, and the inner end of the conductive needle 4 can be fixed to (welded or fixed by glue) the circuit board of the information collection module 5, so that the conductive needle 4 is fixed.

[0036] In summary, the present invention can solve the problem of interface calibration of various liquids whose liquid interfaces are difficult to obtain through observation. The present invention is suitable for closed and high-pressure scenes, and solves the problem of not being able to automatically determine the position of the liquid interface.
