Description

Technical Field

[0001] This utility model relates to the field of alcohol-based liquid fuel storage technology, specifically a safe, intelligent, explosion-proof alcohol-based liquid fuel storage tank. Background Technology

[0002] Alcohol-based liquid fuels, as an environmentally friendly alternative energy source, are increasingly being used in industrial production, commercial catering, and civilian sectors due to their advantages such as wide availability, high combustion efficiency, and low pollutant emissions. Storage tanks, as the core equipment for the storage and supply of alcohol-based liquid fuels, directly affect the reliability and safety of the fuel throughout its entire lifecycle.

[0003] Most alcohol-based liquid fuel storage tanks on the market today transport and store fuel through external pipelines. However, during the fuel filling process, these tanks largely rely on manual observation to determine the liquid level, lacking control over the filling amount. On the one hand, overfilling is prone to occur, leading to fuel overflow and evaporation. Excessive liquid also compresses the gas phase space inside the tank, causing a sudden increase in internal pressure, and static electricity is more likely to accumulate during liquid sloshing. On the other hand, if the remaining fuel level is too low, an excessively large gas phase space will form inside the tank, increasing the risk that flammable vapors will mix with air and reach the explosion limit. Moreover, during operations such as filling and unloading, even slight improper operation can easily cause fuel leakage and evaporation, creating an explosive vapor atmosphere around the tank. The combination of uncontrolled liquid level and sealing failure can further cause pressure imbalance inside the tank, which may not only lead to structural damage to the tank but may also draw in outside air when negative pressure forms inside the tank, mixing with the remaining flammable vapors to form an explosive mixture, increasing the probability of an explosion.

[0004] Therefore, we propose a safe, intelligent, explosion-proof alcohol-based liquid fuel storage tank to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a safe, intelligent, explosion-proof alcohol-based liquid fuel storage tank to solve the problem mentioned in the background art, which is caused by the superposition of uncontrolled liquid level and sealing failure in existing storage tanks, resulting in pressure imbalance, tank damage, and the formation of explosive mixtures, thereby increasing the probability of explosion accidents.

[0006] This utility model provides the following technical solution: a safe, intelligent, explosion-proof alcohol-based liquid fuel storage tank, comprising an alcohol-based liquid fuel tank, a pull ring fixed on the alcohol-based liquid fuel tank, a base fixed to the bottom of the alcohol-based liquid fuel tank, a refueling component installed on the alcohol-based liquid fuel tank, a pressure balancing valve installed on the alcohol-based liquid fuel tank, an alarm component provided on the alcohol-based liquid fuel tank, a liquid level monitoring component installed inside the alcohol-based liquid fuel tank, an antistatic epoxy coating on the inner wall of the alcohol-based liquid fuel tank, and explosion-proof coatings on both the inner and outer walls of the alcohol-based liquid fuel tank.

[0007] Preferably, the alcohol-based liquid fuel tank is connected to a supply pipe at one end, the supply pipe is connected to a control pump at one end, and the control pump is connected to an output pipe at one end.

[0008] Preferably, the refueling assembly includes a sleeve connected to the alcohol-based liquid fuel tank, a fixing plate fixed inside the alcohol-based liquid fuel tank, a spring fixed on the fixing plate, a sealing plate fixed on the spring, the sealing plate sliding against the sleeve, a liquid supply pipe fixed on the sealing plate, and a liquid supply port opened on the side wall of the liquid supply pipe.

[0009] Preferably, the alarm component includes a mounting plate fixed to the side wall of the pressure balancing valve, an audible and visual alarm is fixed on the mounting plate, and a trigger button is installed at the bottom of the audible and visual alarm.

[0010] Preferably, the alcohol-based liquid fuel tank is connected to a sealing tube, and a cavity is formed inside the sealing tube. A second spring is fixed to the inner wall of the cavity, and a float plate is fixed to the bottom of the second spring. The float plate slides against the inner wall of the sealing tube. A sliding rod is fixed to the top of the float plate, and a sealing ring is installed on the top of the sealing tube. The sliding rod slides against the sealing ring, and a contact is fixed to the top of the sliding rod. The contact is coaxially arranged with the trigger button.

[0011] Preferably, the liquid level monitoring component includes an outer cylinder fixed to the bottom surface of the fixed plate, a groove is provided inside the outer cylinder, a slider is slidably connected inside the groove, a compression spring is fixed to the inner wall of the groove, the compression spring is fixedly connected to the slider, a sensor is fixed to the inner wall of the groove, and an abutment ball is fixed to the top surface of the slider.

[0012] Preferably, a horizontal plate is fixed inside the alcohol-based liquid fuel tank, an outer cylinder is fixed on the horizontal plate, a groove is formed inside the outer cylinder, a slider is slidably connected inside the groove, a compression spring is fixed to the inner wall of the groove, the compression spring is fixedly connected to the slider, a sensor is fixed to the inner wall of the groove, and a contact ball is fixed to the bottom surface of the slider.

[0013] Preferably, a fixing rod is fixed between the fixing plate and the cross plate, and a float is slidably connected to the fixing rod. The float, slider one, and slider two are coaxially arranged.

[0014] This utility model has the following beneficial effects: 1. This storage tank achieves precise dual control over both the fuel filling amount and the remaining amount through a liquid level monitoring component, reducing the risk of explosion caused by abnormal liquid levels from the source. The maximum liquid level alarm function can promptly remind the tank to shut down when the liquid is about to exceed the limit, avoiding sudden pressure rises, tank damage, and static electricity buildup caused by liquid sloshing due to insufficient vapor space, while also reducing the risk of fuel spillage. The minimum liquid level alarm prevents the formation of excessive vapor space inside the tank, avoiding the mixing of flammable vapor and air to the explosive limit, and also reduces the possibility of negative pressure suction forming an explosive mixture, ensuring that the fuel storage is always within a safe range.

[0015] 2. The refueling assembly in this storage tank adopts a structure that is triggered by external force and automatically seals without external force. During liquid injection, the liquid supply port precisely aligns with the internal space of the tank to prevent fuel leakage and volatilization from forming an explosive vapor atmosphere. After liquid injection is completed, the spring-driven sealing plate tightly fits the sleeve, which not only prevents fuel volatilization inside the tank but also prevents outside air from entering. This ensures a tight seal from the liquid injection stage to the storage stage, reducing the probability of flammable vapors mixing with air.

[0016] 3. The storage tank utilizes an alarm system to monitor the working status of the pressure balancing valve in real time. When the pressure balancing valve becomes uncontrolled due to blockage by impurities, the high pressure inside the tank will push the float plate, triggering an audible and visual alarm, promptly alerting personnel to inspect and clear the blockage. This design prevents tank damage caused by continuous pressure increases and also prevents the formation of an explosive mixture from air intake under negative pressure, providing dual safety protection in conjunction with liquid level control.

[0017] 4. The antistatic epoxy coating on the inner wall of the storage tank isolates the fuel from contact with the tank wall, preventing corrosion-induced reduction in tank strength. Simultaneously, it promptly conducts static electricity generated by friction to the ground, preventing the accumulation of static electricity and the generation of electric sparks. The explosion-proof coatings on both the inner and outer walls further enhance the structural strength and corrosion resistance of the tank, resisting external environmental erosion and internal pressure fluctuations, ensuring the integrity of the tank, and blocking the explosion path caused by corrosion and static electricity at the material level.

[0018] 5. The various components within this storage tank work together to form a three-in-one explosion-proof system encompassing level control, pressure monitoring, and material protection, covering the entire lifecycle of fuel storage, filling, use, and transportation. This system not only mitigates potential risks at the source but also provides rapid early warnings in the early stages of a potential hazard, effectively reducing the possibility of flammable vapor mixing and ignition sources, thus decreasing the probability of explosions. With its stable explosion-proof performance and reliable operation, it provides a solid equipment guarantee for the promotion and application of alcohol-based liquid fuels as an energy source.

[0028] 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.

[0029] Example 1: This example aims to address the explosion risk caused by overfilling or underfilling of alcohol-based liquid fuel storage tanks. Please refer to [link to relevant documentation]. Figure 1 - Figure 7 A safe, intelligent, explosion-proof alcohol-based liquid fuel storage tank includes an alcohol-based liquid fuel tank 1, a pull ring 101 fixed on the alcohol-based liquid fuel tank 1, a base 102 fixed at the bottom of the alcohol-based liquid fuel tank 1, a supply pipe 2 connected to one end of the alcohol-based liquid fuel tank 1, a control pump 3 connected to one end of the supply pipe 2, an output pipe 4 connected to one end of the control pump 3, a replenishment assembly 5 installed on the alcohol-based liquid fuel tank 1, the replenishment assembly 5 including a sleeve 51 connected to the alcohol-based liquid fuel tank 1, a fixing plate 52 fixed inside the alcohol-based liquid fuel tank 1, a spring 53 fixed on the fixing plate 52, a sealing plate 54 fixed on the spring 53, the sealing plate 54 sliding against the sleeve 51, a liquid supply pipe 55 fixed on the sealing plate 54, and a liquid supply port 56 opened on the side wall of the liquid supply pipe 55.

[0030] The alcohol-based liquid fuel tank 1 is equipped with a liquid level monitoring component 8. The liquid level monitoring component 8 includes an outer cylinder 83 fixed to the bottom surface of a fixed plate 52, a groove 84 is provided inside the outer cylinder 83, a slider 85 is slidably connected inside the groove 84, a compression spring 86 is fixed to the inner wall of the groove 84, the compression spring 86 is fixedly connected to the slider 85, a sensor 87 is fixed to the inner wall of the groove 84, and a contact ball 88 is fixed to the top surface of the slider 85.

[0031] A horizontal plate 801 is fixed inside the alcohol-based liquid fuel tank 1. An outer cylinder 802 is fixed on the horizontal plate 801. A groove 803 is opened inside the outer cylinder 802. A slider 804 is slidably connected inside the groove 803. A compression spring 805 is fixed on the inner wall of the groove 803. The compression spring 805 is fixedly connected to the slider 804. A sensor 806 is fixed on the inner wall of the groove 803. A contact ball 807 is fixed on the bottom surface of the slider 804. A fixing rod 81 is fixed between the fixing plate 52 and the horizontal plate 801. A float 82 is slidably connected on the fixing rod 81. The float 82, slider 85, and slider 804 are coaxially arranged.

[0032] In this embodiment: When using the alcohol-based liquid fuel tank 1 to store alcohol-based liquid fuel, the alcohol-based liquid fuel is first injected into the alcohol-based liquid fuel tank 1. The injection operation is completed by the replenishment component 5. Specifically, the external injection pipe is aligned with the supply pipe 55 and inserted and squeezed. Since the supply pipe 55 is fixedly connected to the sealing plate 54, and the sealing plate 54 is elastically connected to the fixing plate 52 by the spring-53, the squeezing force of the injection pipe will drive the supply pipe 55 and the sealing plate 54 to move synchronously, so that the sealing plate 54 compresses the spring-53 and disengages from the sealed and fitted state of the sleeve 51.

[0033] At this time, the liquid supply port 56 on the side wall of the liquid supply pipe 55 is aligned with the internal space of the alcohol-based liquid fuel tank 1. The alcohol-based liquid fuel is smoothly injected into the tank through the liquid supply port 56. This structure can prevent fuel leakage and volatilization during the injection process, thus avoiding the formation of an explosive atmosphere.

[0034] As the alcohol-based liquid fuel is continuously injected, the liquid level in the tank gradually rises. Under buoyancy, the float 82 slides upwards along the fixed rod 81. It's worth noting that the float 82, along with the sliders 85 and 804 in the liquid level monitoring assembly 8, are coaxially aligned. This structure ensures that the rise and fall of the float 82 accurately targets the monitoring mechanism, avoiding triggering deviations. When the liquid level reaches the maximum safe volume threshold designed for the storage tank, the float 82 contacts the slider 85 inside the outer cylinder 83, pushing it to compress the spring 86 along the groove 84. As the slider 85 moves progressively, the contact ball 88 fixed to its top surface gradually approaches the sensor 87 on the inner wall of the groove 84, ultimately triggering a contact. Since the sensor 87 is electrically connected to the alarm system, once the contact signal is generated, the alarm immediately emits an audible and visual alarm signal, prompting the operator to stop the injection, thereby strictly controlling the liquid filling volume and eliminating the risk of overfilling.

[0035] This measure effectively mitigates multiple risks associated with excessive liquid. For instance, alcohol-based fuels are highly volatile. If excessive liquid leads to a small gas phase space, the flammable vapors cannot diffuse sufficiently. The pressure inside the tank will rise rapidly due to factors such as increased ambient temperature and exposure to sunlight. If this pressure exceeds the tank's design pressure limit, it may cause tank deformation, leakage, or even physical rupture. After rupture, the flammable vapors will leak out instantly and mix with air to form an explosive mixture, which could ignite upon contact with an ignition source. Furthermore, if the tank experiences shaking, such as during vehicle transport or external disturbance, the excessive liquid will violently impact the tank walls, potentially damaging the internal structure and generating a large amount of static electricity. The small gas phase space makes it difficult for this static electricity to dissipate, easily igniting the flammable vapors with an electric spark. Excessive liquid can also easily overflow during filling due to metering errors, causing the volatile vapors to form an explosive zone around the tank, further amplifying the safety risks.

[0036] After the liquid injection operation is completed, the operator removes the external liquid injection pipe. The liquid supply pipe 55 loses external pressure, and spring 53 immediately activates and elastically resets, causing the sealing plate 54 to re-fit tightly against the sleeve 51, achieving a seal inside the tank. This sealing design effectively prevents fuel evaporation and leakage inside the tank, while also preventing outside air from entering, reducing the probability of flammable vapors mixing with air at the source, further lowering the risk of explosion. This completes the liquid injection process.

[0037] When fuel is needed, connect the supply pipe 2 to the alcohol-based liquid fuel tank 1. After installing the control pump 3, connect the output pipe 4 to the stove or other energy-consuming device. Starting the control pump 3 will ensure a stable fuel supply. During use, the liquid level in the tank decreases continuously as fuel is consumed, and the float 82 slides downwards along the fixed rod 81 in sync. When the liquid level drops to the minimum safe volume range designed for the quasi-alcohol-based liquid fuel tank 1, the float 82 contacts the slider 804 inside the outer cylinder 802, pushing the slider 804 to compress the spring 805 along the groove 803. The contact ball 807 on the bottom surface of the slider 804 contacts the sensor 806 on the inner wall of the groove 803. The sensor 806 is electrically connected to the alarm. When triggered, the alarm emits an alarm signal, reminding staff to replenish fuel in time.

[0038] This design effectively addresses the explosion risk caused by insufficient liquid level. Because alcohol-based fuels have a wide explosion limit, when the liquid level is low, a large amount of space inside the tank is occupied by air. The flammable vapors produced by liquid evaporation mix thoroughly with the air, easily reaching the explosion limit. Furthermore, if the tank is a closed structure, the pressure inside may drop to negative pressure during liquid reduction. If the seal is not tight, air may be drawn in, mixing with residual flammable vapors to form an explosive mixture that can ignite upon contact with an ignition source. Timely replenishment via a minimum liquid level alarm can avoid these risks.

[0039] The liquid level monitoring component 8 ensures that the liquid level in the storage tank remains within a safe range throughout the entire storage and use cycle by accurately monitoring both the highest and lowest liquid levels. This fundamentally cuts off the risk chain of explosions indirectly caused by abnormal liquid levels, providing core protection for the safe storage and use of alcohol-based liquid fuels.

[0040] Example 2: This example aims to address the risk of explosion due to pressure runaway caused by blockage of pressure balance valve 6 in alcohol-based liquid fuel storage tanks. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figure 1 - Figure 4 The alcohol-based liquid fuel tank 1 is equipped with a pressure balancing valve 6 and an alarm component 7. The alarm component 7 includes a mounting plate 71 fixed to the side wall of the pressure balancing valve 6, an audible and visual alarm 72 fixed on the mounting plate 71, and a trigger button 73 installed at the bottom of the audible and visual alarm 72.

[0041] An alcohol-based liquid fuel tank 1 is connected to a sealing tube 74. A cavity 75 is opened inside the sealing tube 74. A second spring 76 is fixed to the inner wall of the cavity 75. A float 77 is fixed to the bottom of the second spring 76. The float 77 slides against the inner wall of the sealing tube 74. A slide rod 78 is fixed to the top of the float 77. A sealing ring 79 is installed on the top of the sealing tube 74. The slide rod 78 slides against the sealing ring 79. A contact 710 is fixed to the top of the slide rod 78. The contact 710 is coaxially arranged with the trigger button 73.

[0042] In this embodiment: alcohol-based liquid fuel may contain impurities due to insufficient purity during production and storage. After long-term use, these impurities can easily accumulate and clog the pressure balancing valve 6. The pressure balancing valve 6 is a core component for maintaining stable pressure inside the tank. Once clogged, the combustible vapors generated by fuel volatilization cannot be discharged in time, and the pressure will continue to rise. At the same time, if negative pressure occurs inside the tank, the outside air cannot replenish and balance it in time, which may lead to damage to the tank structure or the formation of an explosive gas mixture.

[0043] In this embodiment, the alarm component 7 monitors the working status of the pressure balancing valve 6 in real time. When the pressure balancing valve 6 is working normally, the pressure inside the alcohol-based liquid fuel tank 1 is maintained within a safe range. The float 77 inside the cavity 75 of the sealing tube 74 remains stable under the support of the second spring 76. The contact 710 at the top of the slide rod 78 remains separated from the trigger button 73 of the audible and visual alarm 72, and the audible and visual alarm 72 does not work. When the pressure balancing valve 6 becomes blocked, the pressure inside the alcohol-based liquid fuel tank 1 gradually increases as combustible vapor accumulates. High-pressure gas enters the cavity 75 through the sealing tube 74, generating an upward thrust on the float 77. When the thrust is greater than the elastic force of the second spring 76, the float 77 slides upward along the inner wall of the sealing tube 74, causing the slide rod 78 to move upward synchronously. The contact 710 at the top of the slide rod 78 gradually approaches and presses the trigger button 73. After the trigger button 73 is triggered, the audible and visual alarm 72 immediately emits an audible and visual alarm signal, reminding the staff to promptly inspect and unclog the pressure balancing valve 6.

[0044] This structure can quickly respond to blockages in the pressure balancing valve 6, preventing tank rupture and flammable vapor leakage caused by pressure runaway. Combined with the level control in Example 1, it further enhances the safety and explosion-proof performance of the storage tank. The sealing ring 79 at the top of the sealing pipe 74 ensures the tank's seal during the sliding of the slide rod 78, preventing fuel vapor from leaking through the gap between the slide rod 78 and the sealing pipe 74.

[0045] Example 3: This example aims to address the explosion risk caused by corrosion damage and static electricity buildup in alcohol-based liquid fuel storage tanks. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figure 8 The inner wall of the alcohol-based liquid fuel tank 1 is provided with an antistatic epoxy coating 10, and both the inner and outer walls of the alcohol-based liquid fuel tank 1 are provided with an explosion-proof coating 9.

[0046] In this embodiment, a special coating is applied to both the inner and outer walls of the storage tank to construct an explosion-proof barrier from a material protection perspective. On one hand, alcohol-based liquid fuels have certain chemical reactivity, and long-term storage may corrode the inner wall of the tank, leading to thinning of the tank wall and decreased strength. This makes the tank prone to rupture when pressure fluctuates, and the leaked fuel can evaporate to form an explosive gas mixture. On the other hand, static electricity is generated when the fuel sloshes inside the tank or rubs against the tank wall. If this static electricity cannot be dissipated in time, it can accumulate to a certain voltage, generating an electric spark that ignites flammable vapors within the explosive limits of the tank, causing an explosion.

[0047] To address the aforementioned risks, this embodiment provides an antistatic epoxy coating 10 on the inner wall of the alcohol-based liquid fuel tank 1. The epoxy coating possesses excellent chemical stability, effectively isolating the fuel from direct contact with the tank wall and preventing corrosion. Simultaneously, the antistatic components enhance the coating's conductivity, allowing static electricity generated by friction between the fuel and the tank wall to be promptly conducted to the ground, preventing static buildup. The explosion-proof coating 9 on both the inner and outer walls of the tank further enhances its structural strength and corrosion resistance. Even under external environmental erosion or slight internal pressure fluctuations, the tank's integrity is maintained. From both physical protection and static electricity dissipation perspectives, it blocks the explosion path caused by corrosion and static electricity, forming a multi-faceted explosion-proof system together with the liquid level and pressure control in the previous embodiment.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
