[0043] As described in the background, the liquid level monitoring pipe is a pipe arranged for monitoring the level of the liquid in the liquid container. The liquid in the pipe often condenses, and the condensed liquid can cause the liquid level sensor to be misdetected and transmit an incorrect signal.
[0044] To solve the above technical problems, the present embodiment provides a liquid level monitoring pipe and a liquid level monitoring system for monitoring the position of the top surface of the liquid in the liquid container. A liquid level monitoring pipe comprises: an outlet pipe, a first end of the outlet pipe being in communication with a first interface below the liquid container; a liquid level monitoring pipe, a first end of the liquid level monitoring pipe being in communication with a second end of the outlet pipe, and the liquid container, the outlet pipe and part or all of the liquid level monitoring pipe forming a communication device; a communication pipe, a first end of the communication pipe being in communication with a second interface above the liquid container, and a second end of the communication pipe being in communication with a second end of the liquid level monitoring pipe; wherein the material of the inner wall surface of at least a part of the liquid level monitoring pipe is a hydrophobic material, and the surface roughness is within a predetermined surface roughness range.
[0045] The liquid level monitoring pipeline and the liquid level monitoring system are used for monitoring the liquid surface position in the liquid level monitoring pipeline. The inner wall surface of at least a part of the liquid level monitoring pipeline is made of a hydrophobic material, and the surface roughness is within a preset surface roughness range, so that the inner surface of the liquid level monitoring pipeline is not easy to condense liquid, and even if condensation occurs, the liquid can slide down as soon as possible, thereby effectively solving the problem of false detection of the liquid level sensor caused by condensed liquid.
[0046] In order to make the above-mentioned purposes, features and advantages of the present disclosure more obvious and easy to understand, the present disclosure will be clearly and completely illustrated below with reference to the drawings.
[0047] Referring to Figure 1 , Figure 1 A schematic diagram of a liquid level monitoring system including a liquid level monitoring pipeline in an embodiment of the present disclosure is shown.
[0048] In this embodiment, the liquid level monitoring system can include a liquid level monitoring pipeline, a liquid container 200, and a liquid level sensor 300.
[0049] The two ends of the liquid level monitoring pipeline are in communication with the two interfaces of the liquid container 200; one or more liquid level sensors 300 are located outside the liquid container 200 and face the liquid level monitoring pipeline.
[0050] In some embodiments, when the liquid level monitoring pipeline and the liquid container 200 form a communication device, the space in which the liquid in the liquid level monitoring system is located is a closed space.
[0051] The liquid level monitoring pipeline and the liquid container 200 form a communication device, and because the pressure of the liquid in the closed container is equal, when the communication device contains the same liquid and the liquid is stationary, the liquid level height in the two pipelines is equal. Because the pressure of the liquid level on both sides is equal, the pressure is also equal, so the liquid level remains flat. Therefore, the liquid level height in the liquid level monitoring pipeline can directly show the liquid level height in the liquid container 200. By arranging the liquid level sensor 300 on the outer surface of the liquid level monitoring pipeline, the position of the top surface of the liquid in the liquid container 200 can be indirectly monitored.
[0052] Specifically, the liquid level monitoring pipeline includes an outlet pipe 110, a liquid level monitoring pipe 120, and a connecting pipe 130. The first end of the outlet pipe 110 is connected to a first interface below the liquid container 200; the first end of the liquid level monitoring pipe 120 is connected to the second end of the outlet pipe 110, and the liquid container 200, the outlet pipe 110, and part or all of the liquid level monitoring pipe 120 form a communicating vessel; the first end of the connecting pipe 130 is connected to a second interface above the liquid container 200, and the second end of the connecting pipe 130 is connected to the second end of the liquid level monitoring pipe 120.
[0053] It should be noted that the above-mentioned connection method can be a detachable connection such as screw connection or snap-fit connection, or a non-detachable connection such as welding, bonding, or integral molding. Among them, the detachable connection method facilitates the replacement of the liquid level monitoring tube 120 according to different liquids, while the non-detachable connection method has better sealing performance and is less prone to leakage.
[0054] In some embodiments, the material of the inner wall surface of the liquid level monitoring tube 120 is a hydrophobic material.
[0055] In some embodiments, at least a portion of the inner wall surface of the liquid level monitoring tube 120 is made of a hydrophobic material. This material allows liquid to slide off the inner surface of the liquid level monitoring tube 120 when liquid condenses on the inner surface.
[0056] In some embodiments, the surface roughness of the liquid level monitoring tube 120 is within a preset surface roughness range.
[0057] Specifically, surface roughness refers to the unevenness of a surface, characterized by small gaps and tiny peaks and valleys. The distance between two peaks or valleys (wavelength) is very small, and it belongs to microscopic geometric shape errors. The smaller the surface roughness, the smoother the surface.
[0058] Combined with reference Figures 1 to 4 ,in, Figure 2 A schematic diagram of a liquid container including a liquid level monitoring pipe is shown in an embodiment of the present disclosure; Figure 3 A cross-sectional schematic diagram of a first type of liquid level monitoring pipeline according to an embodiment of this disclosure is shown; Figure 4 A cross-sectional schematic diagram of a second type of liquid level monitoring pipeline is shown in an embodiment of this disclosure.
[0059] In some embodiments, the preset surface roughness range is selected from: the international standard level corresponding to surface roughness Ra is 3 to the international standard level corresponding to surface roughness Ra is 5, and the range of surface roughness Ra is 0.1μm to 0.4μm.
[0060] Specifically, a rough hydrophobic material surface increases the contact area with air, thus forming an air layer on the surface. This air layer hinders direct contact between water molecules and the material surface, thereby enhancing hydrophobic properties. According to the Cassie model, when a liquid is suspended on the grooves of a rough surface, it cannot completely fill the grooves but can only contact the convex surface. In other words, the rougher the hydrophobic material surface, the smaller the actual contact area between the liquid and the material surface, thus improving hydrophobic performance.
[0061] In some embodiments, the surface roughness of at least a portion of the inner wall of the liquid level monitoring tube 120 can be selected based on the viscosity of the liquid within the liquid level monitoring tube 120. Since a more viscous liquid is more likely to adhere to the inner wall of the liquid level monitoring tube 120, a higher surface roughness should be selected for at least a portion of the inner wall of the liquid level monitoring tube 120. This allows the liquid to slide off more easily, further reducing adhesion, based on the hydrophobic material. It should be noted that microscopic and macroscopic roughness can be indicated by a surface roughness Ra gradation.
[0062] In a non-limiting embodiment, roughness in this application can be referred to as macroscopic roughness, such as that which is visible to the naked eye or with the aid of a magnifying glass, according to Ra > 0.4 μm (e.g., Ra grade greater than 5); roughness in this application can be referred to as microscopic roughness, such as that which is visible with the aid of optical instruments, according to Ra grade less than or equal to 5.
[0063] In this embodiment of the invention, by setting the Ra level to be greater than or equal to 3, the inner wall surface of the liquid level monitoring tube can be prevented from being too smooth, so that liquid is not easy to condense on the inner surface of the liquid level monitoring tube, and even if condensation occurs, the liquid can slide off quickly; by setting the Ra level to be less than or equal to 5, microscopic roughness can be obtained, preventing the inner wall surface of the liquid level monitoring tube from being too rough at the macroscopic level, and reducing the possibility of liquid being stored in the depression of an overly rough surface.
[0064] In some embodiments, refer to Figure 3 The liquid level monitoring tube 120 (refer to) Figure 1 The pipe wall is a multilayered material, for example, including an outer pipe 120a and an inner pipe 120b. The material of the inner wall surface of the inner pipe 120b is selected from one or more of the following: polyethylene, polyvinyl chloride, polytetrafluoroethylene, polyvinylidene fluoride, and polycarbonate.
[0065] In some embodiments, refer to Figure 4 The liquid level monitoring tube 120 (refer to) Figure 1 The pipe wall is a single-layer material, such as Figure 4The 120c shown is selected from one or more of the following: polyethylene, polyvinyl chloride, polytetrafluoroethylene, polyvinylidene fluoride, and polycarbonate.
[0066] It should be noted that the material of the liquid level monitoring tube 120 should be selected based on the chemical properties of the liquid in the liquid level monitoring tube 120, and different materials should be selected accordingly.
[0067] In some embodiments, the liquid level monitoring tube 120 is made of a transparent or semi-transparent material. In some processes, it is necessary to first confirm whether there is enough liquid in the liquid container 200; a transparent or semi-transparent material allows for convenient, intuitive, and quick determination of the liquid level.
[0068] In some embodiments, the liquid level monitoring tube 120 has a middle section, which is a section whose inner wall surface is made of a hydrophobic material.
[0069] In some embodiments, the middle section of the pipe is a section whose inner wall surface is made of a hydrophobic material, and / or, the middle section of the liquid level monitoring pipe 120 is a vertical section of the liquid level monitoring pipe 120.
[0070] Specifically, the liquid level sensor 300 is disposed on the outer surface of the middle section of the pipe. The middle section of the pipe is a section whose inner wall surface is made of a hydrophobic material, and / or a vertical section in the liquid level monitoring tube 120. This arrangement allows liquid condensing on the inner wall surface of the middle section of the pipe, and / or allows liquid flowing down from above the middle section of the pipe to quickly slide off. Since the liquid level sensor 300 can easily misinterpret condensed liquid as the surface position of liquid, reducing the amount of condensed liquid can lower the probability of false detection by the liquid level sensor 300.
[0071] In some embodiments, the connecting pipe 130 is L-shaped or U-shaped, and the liquid level monitoring pipe 120 is I-shaped, L-shaped or U-shaped; wherein, the inner wall of the second end of the connecting pipe 130 has a protrusion 140 at a position facing the central axis of the middle section of the pipe of the liquid level monitoring pipe 120.
[0072] like Figure 1 and / or Figure 2 As shown, the protrusion 140 is oriented toward the central axis of the liquid level monitoring tube 120.
[0073] In some embodiments, the connecting pipe 130 is I-shaped or L-shaped, the liquid level monitoring pipe 120 is L-shaped or U-shaped, and the inner wall of the second end of the liquid level monitoring pipe 120 has a protrusion 140 at a position facing the central axis of the middle section of the pipe of the liquid level monitoring pipe 120.
[0074] Specifically, liquid condensed on the inner wall of the pipe above the connecting pipe 130 can drip down from the protrusion 140 along the direction of gravity. Since the inner wall of the middle section of the pipe is made of hydrophobic material and / or is a vertical section (perpendicular to the ground), the liquid dripping from the protrusion 140 along the direction of gravity can pass through the center of the middle section of the pipe or drip onto the inner wall of the middle section of the pipe and slide down quickly, thereby reducing the probability of the liquid level sensor 300 falsely detecting the liquid condensed.
[0075] In some embodiments, the conduit between the protrusion 140 and the second interface above the liquid container 200 has a frustum portion and a cylindrical portion.
[0076] The top of the frustum portion is connected to the protrusion 140, the bottom of the frustum portion is connected to the first end of the cylindrical portion, and the second end of the cylindrical portion is coupled to the second interface.
[0077] In some embodiments, the frustum axis of the frustum portion is perpendicular to the central axis of the middle section of the liquid level monitoring tube 120.
[0078] Specifically, the area of the top where the frustum connects to the protrusion 140 is smaller than the area of the bottom where the frustum connects to the first end of the cylindrical portion. Both the frustum and the cylindrical portion are hollow pipes, and their areas, shapes, and sizes are identical at the points where they connect.
[0079] It should be noted that some of the liquid condensed in the frustum portion can flow along the inclined inner surface of the frustum portion to the protrusion 140, and then drip from the protrusion 140 in the direction of gravity; other parts can flow along the inclined inner surface of the frustum portion to the cylindrical portion. This reduces the amount of liquid flowing into the middle section of the liquid level monitoring tube 120 along the inner surface of the pipe, thereby reducing the probability of false detection by the liquid level sensor 300 due to condensed liquid.
[0080] In some embodiments, the conduit between the protrusion 140 and the second interface above the liquid container 200 has a first end and a second end.
[0081] The first end is connected to the protrusion 140, and the second end is coupled to the second interface;
[0082] In some embodiments, the height of the first end of the pipe between the protrusion 140 and the second interface above the liquid container is equal to the height of the second end.
[0083] In some embodiments, the height of the first end of the pipe between the protrusion 140 and the second interface above the liquid container is greater than the height of the second end.
[0084] The extension direction of the height is parallel to the central axis of the middle section of the liquid level monitoring tube 120, and the liquid condensed on the inner wall of the tube between the protrusion 140 and the second interface above the liquid container 200 can flow from the first end to the second end of the tube between the protrusion 140 and the second interface above the liquid container 200 due to gravity. This structure can also reduce the amount of liquid flowing into the middle section of the liquid level monitoring tube 120 along the inner surface of the tube, thereby reducing the probability of false detection by the liquid level sensor 300 due to condensed liquid.
[0085] In some embodiments, the outlet pipe 110 has a three-end structure, having not only a first end and a second end that are respectively connected to the first interface below the liquid container 200 and the first end of the liquid level monitoring pipe 120, but also a third end that is connected to the liquid output pipe. Liquid in the liquid container 200 flows into the outlet pipe 110 from the first interface below the liquid container 200, and then flows into the liquid output pipe from the third end of the outlet pipe 110 to output liquid.
[0086] In some embodiments, the liquid level sensor 300 is a capacitive liquid level sensor; the capacitive liquid level sensor is disposed on the outer surface of the middle section of the liquid level monitoring pipe 120.
[0087] The capacitive liquid level sensor utilizes the sensing capacitance of the liquid in the liquid container 200 to detect the presence of liquid. When no liquid approaches the sensor, the sensor has a certain static capacitance to ground due to the presence of distributed capacitance. As the liquid level slowly rises and approaches the sensor, the parasitic capacitance of the liquid will couple to this static capacitance, increasing the final capacitance value of the sensor. This changing capacitance signal is then input to the control IC for signal conversion, transforming the changing capacitance into a change in a certain electrical signal. A certain algorithm then detects and judges the degree of this change. When this change exceeds a certain threshold, the liquid level is considered to have reached the sensing point.
[0088] In some embodiments, the liquid level sensor 300 is a photoelectric liquid level sensor; the photoelectric liquid level sensor utilizes the principle of reflection and refraction of light at the interface of two different media, and is a novel contact-type point liquid level measurement and control device. The photoelectric liquid level sensor internally includes a near-infrared light-emitting diode (LED) and a photosensitive receiver. The light emitted by the LED is guided to a lens at the top of the sensor. When the liquid submerges the lens of the photoelectric liquid level switch, the light is refracted into the liquid, causing the receiver to receive little or no light. By sensing this change in operating condition, the receiver can drive an internal electrical switch, thereby activating an external alarm or control circuit. If there is no liquid, the light emitted by the LED is directly reflected back to the receiver from the lens.
[0089] In some embodiments, the number of liquid level sensors 300 may be one, which is positioned at a preset liquid replacement location facing the liquid level monitoring pipe. When the liquid level in the liquid level monitoring pipe 120 is at the preset liquid replacement location, the signal detected by the liquid level sensor 300 will change, thereby transmitting a liquid replacement signal.
[0090] It should be noted that the above examples do not constitute a limitation on the number of liquid level sensors 300. In addition to the one shown in the above examples, the number of liquid level sensors 300 can also be multiple.
[0091] In some embodiments, the number of liquid level sensors 300 can be three, arranged vertically; wherein the bottom liquid level sensor 300 faces the preset liquid replacement position of the liquid level monitoring pipeline.
[0092] Specifically, the liquid level in the liquid container 200 is confirmed before the process begins. The amount of liquid required varies depending on the process. For example, a certain process requires the liquid level to reach at least the position set by the intermediate liquid level sensor 300. If the liquid level is above the position set by the intermediate liquid level sensor 300, no liquid replacement is needed; otherwise, liquid replacement is required.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article indicates that the preceding and following related objects have an "or" relationship.
