Description

Technical Field

[0001] This invention relates to the field of fuel oil testing technology, and more specifically, to a fuel oil explosiveness tester. Background Technology

[0002] If fuel oil is contaminated with small amounts of flammable and explosive substances such as light fuels or hydrocarbon gases during production and storage, and these substances dissolve in the fuel oil, it will not affect the safety indicators such as the flash point of the fuel oil. However, in actual use, due to actions such as heating, stirring, and pumping, flammable and explosive substances will evaporate from the fuel oil and mix with air in the oil-free space above closed containers such as pipelines, oil tanks, and oil tanks, forming an explosive mixture. When the mixture reaches the explosion limit, it will cause a serious explosion accident when it comes into contact with static electricity or an open flame.

[0003] In existing technologies, to test the explosion risk of mixtures of flammable and explosive volatiles in fuel oil with air, compressed air pre-pressurized to a certain pressure is typically introduced into a hot water bottle. Water from the bottle flows into the sample bottle, lifting the fuel oil. Under water pressure, the explosive mixture is discharged through a gas discharge pipe to a drying tube for drying. The dried mixture is then transported to an explosion detector for explosiveness testing. During the generation of the explosive mixture, the sample bottle must be placed in a hot water bath and continuously shaken. This process needs to be repeated multiple times to release the explosive mixture from the oil sample. This method reduces the efficiency of explosive mixture generation, resulting in low efficiency in fuel oil explosiveness testing. Furthermore, the explosive mixture needs to be discharged under water pressure, resulting in the presence of water vapor, requiring an additional drying tube for further drying. This makes the operation of the fuel oil explosiveness testing device quite cumbersome.

[0004] In addition, the discharge rate of the explosive mixture is an important indicator of the accuracy of the measurement. It is generally controlled by adjusting the compressed air flow rate and acting on the warm water. The warm water is discharged and lifts the fuel oil, which makes the discharge rate control process complicated, time-consuming and inaccurate.

[0005] Therefore, how to improve the efficiency of fuel oil explosiveness testing has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0035] The core of this invention is to provide a fuel oil explosiveness tester to improve the efficiency of fuel oil explosiveness testing.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] like Figure 1 As shown, an embodiment of the present invention discloses a fuel oil explosiveness tester 100, including a mixing tank 102, a stirring device 108, a moving device 103, and a measuring component.

[0038] The mixing tank 102 is used to hold the fuel oil sample. It should be noted that the mixing tank 102 is a cylindrical structure with an open top. When determining the explosiveness of the fuel oil sample, the fuel oil sample is added to the mixing tank 102, and the sample is stirred by the stirring device 108 to release explosive gases, which then form an explosive mixture with the air in the upper part of the chamber. It should be noted that the mixing tank 102 can be a cylindrical shape with an open top, or it can be a square prism with an open top; the mixing tank 102 used in this embodiment is cylindrical.

[0039] A stirring device 108 is located at the bottom of the cavity of the mixing tank 102. The stirring device 108 continuously stirs the fuel oil sample, causing explosive gases to be released from the fuel oil sample and mixed with the air above it before being discharged from the cavity of the mixing tank 102. It should be noted that after the explosive gases are released from the fuel oil sample and mixed with air, stirring must continue to ensure thorough mixing. Once the explosive gases are fully mixed with air, an active device is activated to downwardly compress the explosive mixture, causing it to be discharged from the cavity of the mixing tank 102 to the measuring component.

[0040] Specifically, the movable device 103 includes a piston cover 1022 and a drive assembly for driving the piston cover 1022. The piston cover 1022 is located inside the cavity of the mixing tank 102. Under the driving action of the drive assembly, the piston cover 1022 squeezes the explosive mixture downwards, so that the explosive mixture is discharged from the cavity of the mixing tank 102 to the measuring assembly.

[0041] Furthermore, the measuring component is connected to the cavity of the mixing tank 102 so that the explosive mixture is discharged from the cavity of the mixing tank 102 to the measuring component under the action of the movable device 103, and the explosive mixture is measured by the measuring component to obtain the explosive index of the fuel oil sample.

[0042] In one specific embodiment, a fuel oil sample is added to a mixing tank 102. A drive assembly moves the piston cover 1022 up and down, ensuring the volume of air enclosed below the piston cover 1022 is equal to the volume of fuel oil. At this time, a controller controls the resistance wire 1025 and the stirring device 108 to heat and stir the fuel oil sample simultaneously. After the fuel oil sample reaches a specified temperature and is held at that temperature for 5 minutes, the stirring intensity of the stirring device 108 is increased to allow the explosive gases present in the fuel oil sample to fully volatilize and mix with the air above the fuel oil sample. Stirring continues for a period of time, then stops. The drive assembly is then activated to move the piston cover 1022 downwards, allowing the explosive mixture to be discharged from the cavity of the mixing tank 102 to the measuring component. The explosiveness of the explosive mixture is then measured to obtain the explosiveness index of the fuel oil sample. It should be noted that unless otherwise specified, the explosive mixture refers to a mixture of explosive gases and air.

[0043] The fuel oil explosiveness tester 100 provided by the present invention uses a stirring device 108 in a mixing tank 102 to stir the fuel oil sample contained in the mixing tank 102, so that explosive gas is released from the fuel oil sample and forms an explosive mixture with the air in the upper part of the cavity. At the same time, the driving component drives the piston cover 1022 to compress the explosive mixture in the cavity of the mixing tank 102, so that the explosive mixture is discharged from the cavity of the mixing tank 102 to the measuring component connected to the cavity of the mixing tank 102, so as to determine the explosiveness of the explosive mixture and obtain the explosiveness index of the fuel oil sample.

[0044] Compared with the prior art, the fuel oil explosiveness tester 100 provided by the present invention uses a stirring device 108 to stir the fuel oil sample contained in the mixing tank 102, so that the explosive gas is released from the fuel oil sample and forms an explosive mixture with the air in the upper part of the cavity. This avoids the cumbersome operation steps of releasing the explosive gas, improves the release efficiency of the explosive gas, and uses a piston cover 1022 to squeeze the explosive mixture out, so that the discharged explosive mixture does not need to be dried before entering the measuring component for explosiveness determination. This simplifies the steps of fuel oil explosiveness determination and improves the efficiency of fuel oil explosiveness determination.

[0045] Furthermore, such as Figure 3 and Figure 4As shown, the mixing tank 102 includes a tank body 1021 and a heating element. The heating element is disposed on the outside of the tank body 1021 and is used to heat the fuel oil sample inside the tank body 1021, making it easier for explosive gases to be released from the fuel oil sample. Simultaneously, a stirring device 108 is disposed on the base 1026 of the tank body 1021 and continuously stirs the fuel oil sample. In this embodiment, the heating element is a resistance wire 1025 wound around the outer surface of the tank body 1021. A temperature control system controls the resistance wire 1025 to heat the fuel oil sample to a specified temperature. It should be noted that the heating element is not limited to the resistance wire 1025; it can also be an electric heating jacket or other heating elements, which will not be listed here.

[0046] Furthermore, such as Figure 5 and Figure 6 As shown, in one specific embodiment, the stirring device 108 includes a first support member 1082, a second support member 1083, and a second drive motor 1086 for driving the second support member 1083 to rotate. The first support member 1082 is located above the base 1026 and is connected to the base 1026 via a transmission member, allowing the first support member 1082 to rotate around the transmission member. Two stirring blades 1081 are provided on the upper surface of the first support member 1082, respectively located at both ends. A first magnetic suction member 1084 is provided on the lower surface of the first support member 1082. Two first magnetic suction elements 1084 are respectively disposed at both ends of the first support member 1082. A second support member 1083 is located below the base 1026, and its upper surface is provided with two second magnetic suction elements 1085 that cooperate with the first magnetic suction elements 1084. Two second magnetic suction elements 1085 are also disposed at both ends of the second support member 1083, corresponding one-to-one with the first magnetic suction elements 1084. When the second drive motor 1086 drives the second support member 1083 to rotate, the first support member 1082, under the magnetic force of the first magnetic suction elements 1084 and the second magnetic suction elements 1085, is pushed to rotate around the transmission member, thereby achieving stirring of the fuel oil sample. It should be noted that in this embodiment, the second drive motor 1086 is a speed-regulating motor. By adjusting the rotation speed of the second support member 1083, the stirring force of the stirring device 108 can be adjusted.

[0047] Furthermore, such as Figure 6As shown, in one specific embodiment, the transmission component is a support ball 1087. The support ball 1087 is fixed to the center point of the lower surface of the first support member 1082, and a first groove is formed at the center point of the upper surface of the base 1026 to mate with the support ball 1087. The first groove is a curved groove that fits against the outer surface of the support ball 1087, allowing the support ball 1087 to rotate freely within the first groove. Under the support of the support ball 1087, a first gap is formed between the first magnetic member 1084 and the base 1026 of the can 1021, ensuring smoother rotation of the first support member 1082. Simultaneously, a second gap exists between the second magnetic member 1085 and the base 1026 of the can 1021, ensuring smoother rotation of the second support member 1083 under the drive of the second drive motor 1086. It should be noted that the first magnetic attractor 1084 and the second magnetic attractor 1085 in the embodiments of the present invention are neodymium magnets. Of course, other magnetic attractors can also be used, which will not be listed here.

[0048] Furthermore, such as Figure 3 and Figure 4 As shown, in one specific embodiment, the driving assembly includes a first driving motor 1031 and a push rod 1033. The first end of the push rod 1033 is connected to the first driving motor 1031, and the second end is connected to the piston cover 1022, so that the first driving motor 1031 drives the piston cover 1022 to move. The first driving motor 1031 is detachably mounted on the top of the mixing tank 102 via a motor mounting bracket 1032, facilitating cleaning of the interior of the mixing tank 102 after the fuel oil sample explosion test is completed. It should be noted that in this embodiment, the first driving motor 1031 is a speed-adjustable push rod motor. Rotation of the push rod motor causes the push rod 1033 to extend or shorten, thereby driving the piston cover 1022 to move up and down. Adjusting the speed of the push rod motor controls the moving speed of the piston cover 1022. When the piston cover 1022 moves downward at a set speed, the mixed gas sealed by the piston cover 1022 inside the mixing tank 102 is discharged at the set speed. An adjustable-speed push rod motor is used to control the moving speed of the piston cover 1022, so that the explosive mixture is discharged at a set speed. This reduces the control links of the discharge speed, making the discharge speed of the explosive mixture more stable and uniform. This avoids the low accuracy of fuel oil explosiveness measurement due to the unstable discharge speed of the explosive mixture, thereby improving the accuracy of fuel oil explosiveness measurement.

[0049] To ensure a tight seal between the piston cover 1022 and the mixing tank 102 and prevent the explosive mixture from leaking out of the gaps, a second groove is provided on the side of the piston cover 1022, and a sealing ring 1023 is embedded in the second groove. The sealing ring 1023 protrudes from the edge of the piston cover 1022 and fits tightly against the inner wall of the mixing tank 102 to ensure airtightness between the piston cover 1022 and the inner wall of the mixing tank 102.

[0050] Furthermore, such as Figure 1 As shown, the measuring assembly includes a measuring chamber 104 and an oil-gas separator 105. The measuring chamber 104 is used to determine the explosiveness of an explosive mixture, and the oil-gas separator 105 is used to separate oil droplets from the explosive mixture, preventing oil droplets from entering the measuring chamber 104 and damaging the measuring element. An exhaust pipe 1024 is provided on the piston cover 1022, and the oil-gas separator 105 is connected to the exhaust pipe 1024 via a first air guide pipe 106. The measuring chamber 104 is connected to the oil-gas separator 105 via a second air guide pipe 107. When the mixed gas is discharged from the exhaust pipe 1024, it flows into the oil-gas separator 105 through the first air guide pipe 106, separating the oil droplets mixed in the mixture, and then flows into the measuring chamber 104 through the second air guide pipe 107 to detect the explosiveness of the mixed gas.

[0051] Furthermore, such as Figure 7 As shown, in one specific embodiment, the measuring chamber 104 includes a measuring chamber top cover 1041 and a measuring chamber base 1042. The measuring chamber top cover 1041 and the measuring chamber base 1042 are detachably connected. In this embodiment, the measuring chamber top cover 1041 and the measuring chamber base 1042 are connected by threads. The measuring chamber top cover 1041 is provided with an air inlet pipe 1044 and an exhaust port 1045. The air inlet pipe 1044 is connected to a second air guide pipe 107. The measuring chamber base 1042 is provided with a sensor 1043, which is used to detect the explosiveness of the explosive mixture. When the mixed gas enters the cavity inside the measuring chamber 104 through the air inlet pipe 1044, a stable detection environment is formed, so that the sensor 1043 can quickly and accurately determine the explosiveness data of the mixed gas. It should be noted that, since the sensor 1043 is a consumable part and needs to be replaced regularly, the top cover 1041 of the measuring chamber and the base 1042 of the measuring chamber are designed to be detachable to facilitate the replacement of the sensor 1043.

[0052] Furthermore, such as Figure 1 and Figure 2As shown, the fuel oil explosiveness tester also includes a housing 101, with a measuring chamber 104 and an oil-gas separator 105 disposed on the outer surface of the housing 101, and a mixing tank 102 located inside the housing 101. Specifically, the oil-gas separator 105 is located on the side of the housing 101, and the measuring chamber 104 is located on the panel of the housing 101 to facilitate cleaning and replacement of the measuring chamber 104 and the oil-gas separator 105.
