Technical Field
[0001] This utility model belongs to the field of ethanol gasoline storage tank monitoring technology, specifically a real-time detection device for the phase separation state of ethanol gasoline. Background Technology
[0002] With the increasing global demand for renewable energy, ethanol gasoline has been widely promoted as a clean fuel. However, the moisture in ethanol gasoline can cause acid corrosion and electrochemical corrosion of metals, further exacerbating the risks associated with its use.
[0003] Phase separation is closely related to temperature and is also affected by water content. The lower the temperature and the higher the water content, the greater the likelihood of phase separation. The density of ethanol gasoline is significantly affected by external temperature, varying by up to 53 kg / m³ within the range of -30°C to 30°C. 3 This density variation renders traditional float-based detection devices significantly inadequate for monitoring phase separation in ethanol gasoline. Traditional floats are typically designed based on density principles to detect moisture at the bottom of storage tanks. However, the density of the phase separation layer is often lower than that of water, causing traditional floats to unreliably detect phase separation. Furthermore, when the density of the phase separation layer is less than the float's density, the float may fail to trigger an alarm, thus losing its phase separation warning function. This problem is particularly pronounced in low-density phase separation layers, severely impacting the safety and reliability of ethanol gasoline storage.
[0004] Currently, while some solutions on the market attempt to address phase separation issues, they still have limitations. For example, some float devices are only suitable for phase separation layers within a specific density range, failing to meet the comprehensive detection needs of low-density, medium-density, and high-density phase separation layers. Furthermore, existing technologies lack dynamic response capabilities to changes in phase separation layer height, potentially leading to inaccurate detection results or delayed alarms. Therefore, developing a detection device capable of adapting to different density ranges, real-time monitoring of phase separation phenomena, and providing reliable alarms has become a pressing technical challenge in the storage and use of ethanol gasoline. This invention aims to overcome the shortcomings of existing technologies through innovative design and technical means, providing assurance for the safe storage and efficient use of ethanol gasoline. Summary of the Invention
[0005] This invention addresses the problem that existing float sensors cannot effectively detect ethanol-gasoline phase separation layers, proposing a float kit for detecting ethanol-gasoline phase separation and its operating method. The float kit, through a combination of inner and outer floats, solves the detection requirements for low-density, medium-density, and high-density phase separation layers, and achieves accurate monitoring of the liquid state within storage tanks.
[0006] This invention provides a float kit for detecting phase separation of ethanol and gasoline, comprising an inner float and an outer float, wherein: the inner float consists of a frame, a counterweight, and a magnetic ring, and has a density of 790 kg / m³. 3 The internal structure contains a magnetic ring for parameter transmission; the magnetic ring works in conjunction with the waveguide wire to transmit position change signals to the monitoring equipment; the frame is made of oil-resistant material to ensure long-term stability in an ethanol gasoline environment; the counterweight adjusts the material and mass distribution to make the overall density of the internal float reach a predetermined value.
[0007] Furthermore, the outer float consists of a frame and a counterweight, with a density of 820 kg / m³. 3 The frame of the outer float is made of oil-resistant material to ensure structural strength and durability, thereby preventing external liquids from affecting measurement accuracy.
[0008] Specifically, the inner and outer floats are nested, with an overall average density of 810 kg / m³. 3 To accommodate liquids of different densities, the nested design is secured by snap-fit mechanisms, ensuring a stable relative position between the inner and outer floats while facilitating disassembly and maintenance.
[0009] The working method of the present invention includes the following steps: S1: When there is only gasoline in the storage tank, both the inner and outer floats are at the bottom and no phase separation occurs; the initial positions of the inner and outer floats are in contact with the bottom of the storage tank, and the monitoring equipment does not issue an alarm signal at this time.
[0010] S2: When a high-density phase separation layer appears in the storage tank, the inner float and the outer float rise simultaneously to the boundary between the oil and the phase separation layer; the position change of the inner float is transmitted to the monitoring equipment through the magnetic ring and waveguide wire. The monitoring equipment receives the float height change information, determines that phase separation has occurred, and issues an alarm signal.
[0011] S3: When a medium-density phase separation layer appears in the storage tank, the inner float floats at the interface between the oil and the phase separation layer, and the outer float is driven to float by the inner float; the position change of the inner float is transmitted to the monitoring equipment through the magnetic ring and waveguide wire. The monitoring equipment receives the float height change information, judges that phase separation has occurred, and issues an alarm signal.
[0012] S4: When a low-density phase separation layer appears in the storage tank, if the phase separation layer is low, the inner float floats at the interface between the oil and the phase separation layer; the outer float is located at the bottom. If the phase separation layer is high, the inner float is restricted to a certain position. The position change of the inner float is transmitted to the monitoring equipment through the magnetic ring and waveguide wire. The monitoring equipment receives the float height change information, determines that phase separation has occurred, and issues an alarm signal.
[0013] The beneficial effects of this invention are as follows: Through the density combination design of the inner and outer floats, the float kit can adapt to the detection requirements of low-density, medium-density, and high-density phase separation layers. The nested structure of the inner and outer floats, along with the cooperation between the magnetic ring and the waveguide wire, enables accurate detection of the phase separation layer position; the oil-resistant material ensures the long-term reliability of the float kit in an ethanol gasoline environment; and the real-time data transmission function improves the safety and efficiency of tank management. Furthermore, the float kit is compatible with existing automatic tank monitoring systems, facilitating upgrades and retrofits, and has broad application prospects.
[0014] Furthermore, this invention solves the technical problem that traditional float sensors cannot reliably detect low-density phase separation layers through specific structural design and technical implementation. The density of the inner float is 790 kg / m³. 3 The density of the outer float is 820 kg / m³. 3 The average density of both is 810 kg / m³. 3 It can cover the density range of the ethanol gasoline phase separation layer. The cooperation between the magnetic ring and the waveguide wire enables non-contact signal transmission, avoiding the impact of mechanical wear on measurement accuracy.
[0015] Specifically, this invention achieves height detection of phase separation layers with different densities through the relative motion of inner and outer floats. The floating positions of the inner and outer floats change with the liquid density, and their position information is transmitted to the monitoring equipment via waveguide wires. The monitoring equipment calculates the height and range of the phase separation layer based on the received signals, thereby achieving real-time monitoring of the liquid state within the storage tank. The combination of the structural design and operating method of the float assembly provides reliable technical support for the safe management of ethanol gasoline storage tanks.
[0016] In summary, this invention solves the technical challenge of detecting the phase separation layer of ethanol gasoline by combining inner and outer floats, employing a signal transmission mechanism of magnetic rings and waveguide wires, using oil-resistant materials, and providing real-time data transmission capabilities, thereby improving the safety and reliability of storage tank management.

[0019] 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.
[0020] Please see Figure 1 This invention provides a float kit for detecting phase separation in ethanol gasoline, comprising an inner float 1 and an outer float 2. The inner float 1 consists of a frame 3, a counterweight 4, and a magnetic ring 5, with an overall density of 790 kg / m³. 3 The outer float 2 consists of a frame 3 and a counterweight 4, with an overall density of 820 kg / m³. 3 The inner float 1 and the outer float 2 are combined through a nested structure 14, with an overall average density of 810 kg / m³. 3 To meet the detection needs of liquids with different densities and stratification, the float assembly is installed inside the storage tank 9 and works in conjunction with the waveguide wire 6. The position change signal is transmitted through the magnetic ring 5, and finally the data is transmitted to the monitoring equipment 13.
[0021] Please see Figure 2 and Figure 3 The specific structure of the inner float 1 is as follows: Figure 2 As shown, its frame 3 is made of oil-resistant material 8 to ensure long-term stability in an ethanol gasoline environment. A magnetic ring 5 is embedded inside the frame 3, and the magnetic ring 5 is connected to the monitoring device 13 via a waveguide wire 6 to transmit position change signals. The counterweight 4, by adjusting its material and mass distribution, ensures that the overall density of the inner float 1 reaches 790 kg / m³. 3 The specific structure of the external float 2 is as follows: Figure 3 As shown, its frame 3 also uses oil-resistant material 8 to ensure structural strength and durability. The design of the counterweight 4 makes the overall density of the outer float 2 820 kg / m³. 3This avoids the intrusion of external liquids that could affect measurement accuracy.
[0022] Please see Figure 4 The inner float 1 and outer float 2 are nested together via a snap-fit 7. The snap-fit 7 secures the inner and outer floats, ensuring stable relative positions while facilitating disassembly and maintenance. This nested structure 14 allows the inner float 1 and outer float 2 to work collaboratively, adapting to the detection needs of liquids with different densities undergoing stratification. The relative movement range 19 of the inner float 1 and outer float 2 is limited to a certain range to ensure the accuracy and reliability of the detection.
[0023] Please see Figure 5 The signal transmission mechanism between magnetic ring 5 and waveguide wire 6 is as follows: Figure 5 As shown, the magnetic ring 5 is embedded in the skeleton 3 of the inner float 1. When the inner float 1 moves with changes in liquid density, the position of the magnetic ring 5 changes accordingly. The magnetic ring 5 transmits the position change signal to the monitoring device 13 through the waveguide wire 6, forming a signal transmission path 18. This non-contact signal transmission mechanism avoids the impact of mechanical wear on measurement accuracy and improves the reliability and service life of the system.
[0024] Please see Figure 6 The working status of the float assembly inside tank 9 is as follows: Figure 6 As shown. When the storage tank 9 contains only gasoline, both the inner float 1 and the outer float 2 are at their initial positions 16, and no phase separation occurs. At this time, the monitoring device 13 does not issue an alarm signal. When a high-density phase separation layer 10 appears in the storage tank 9, the inner float 1 and the outer float 2 simultaneously rise to the liquid interface 15. The magnetic ring 5 transmits a signal through the waveguide wire 6, and the monitoring device 13 determines that phase separation has occurred and issues an alarm signal. When a medium-density phase separation layer 11 appears in the storage tank 9, the inner float 1 floats at the liquid interface 15, and the outer float is driven to float by the inner float 1. Its position change is transmitted to the waveguide wire 6 through the magnetic ring 5. When a low-density phase separation layer 12 appears in the storage tank 9, if the phase separation layer is low, the inner float 1 floats at the liquid interface 15, and the outer float 2 is at the bottom; if the phase separation layer is high, the inner float 1 is confined to a certain position, and its position change is transmitted to the monitoring device 13 through the waveguide wire 6 to calculate the height and range of the phase separation layer.
[0025] The specific structural innovations are as follows: Density combination design of inner and outer floats: The density of inner float 1 is 790 kg / m³. 3 The density of outer float 2 is 820 kg / m³. 3 The average density of both is 810 kg / m³. 3 This design can cover the density range of the ethanol-gasoline phase separation layer. This density combination design solves the technical problem that traditional float sensors cannot reliably detect low-density phase separation layers.
[0026] Nested structure and snap-fit fixing: The inner float 1 and the outer float 2 are nested together by snap-fit 7, ensuring stable relative positions between them while facilitating disassembly and maintenance. This design improves the structural strength and durability of the float assembly.
[0027] Signal transmission mechanism of magnetic ring and waveguide wire: The magnetic ring 5 is embedded in the skeleton 3 of the inner float 1, and non-contact signal transmission is achieved through the waveguide wire 6, avoiding the impact of mechanical wear on measurement accuracy. This signal transmission mechanism improves the reliability and service life of the system.
[0028] Application of oil-resistant materials: The frames 3 of both the inner float 1 and the outer float 2 are made of oil-resistant material 8, ensuring long-term stability in ethanol gasoline environments. This material selection improves the durability and reliability of the float assembly.
[0029] The specific operation process is as follows: When there is only gasoline in the storage tank 9, both the inner float 1 and the outer float 2 are in the initial position 16, and no phase separation occurs. The monitoring equipment 13 does not issue an alarm signal.
[0030] When a high-density phase separation layer 10 appears inside the storage tank 9, the inner float 1 and the outer float 2 rise to the liquid interface 15 at the same time. Their positional changes are transmitted to the monitoring equipment 13 through the magnetic ring 5 and the waveguide wire 6. The monitoring equipment 13 determines that phase separation has occurred and issues an alarm signal.
[0031] When a medium-density phase separation layer 11 appears in the storage tank 9, the inner float 1 floats at the liquid interface 15. The inner float 1 is driven to float up, and its position change is transmitted to the monitoring device 13 through the magnetic ring 5 and the waveguide wire 6. The monitoring device 13 judges that phase separation has occurred and issues an alarm signal.
[0032] When a low-density phase separation layer 12 appears in the storage tank 9, if the phase separation layer is low, the inner float 1 floats at the liquid interface 15, and the outer float 2 is located at the bottom. If the phase separation layer is high, the inner float 1 is restricted to a certain position, and its position change is transmitted to the monitoring device 13 through the magnetic ring 5 and the waveguide wire 6. The monitoring device 13 determines that phase separation has occurred and issues an alarm signal.
[0033] In summary, this invention solves the technical problem of ethanol gasoline phase separation layer detection through the combination design of inner and outer floats, the signal transmission mechanism of magnetic ring and waveguide wire, oil-resistant material 8, and real-time data transmission function.
