Description

Technical Field

[0001] This invention belongs to the field of thermal safety research of energetic materials and fuel tanks, specifically involving a multi-purpose rapid combustion test device, particularly for the safety research of medium and large-sized ammunition, fuel tanks, oil drums and other explosive materials. Background Technology

[0002] Fire is one of the most common unexpected events during the safe storage, transportation, and use of flammable and explosive materials such as weapons, ammunition, and petroleum products. Therefore, thermal safety has always been a research hotspot for such materials. If flammable and explosive materials are exposed to fire, the energetic materials, flammable and explosive liquids and solids inside may decompose or react chemically with air under thermal stimulation, potentially leading to an explosion or detonation, resulting in significant personal injury and property damage. The rapid combustion test is a fundamental method for verifying the thermal safety of weapons and ammunition, and is currently also applied to explosive materials such as oil drums and fuel tanks. The test aims to assess the ability of an object to react to unexpected thermal stimuli at an acceptable level, testing the reaction of the sample in a severe thermal environment and the time it takes to reach the reaction, and evaluating the thermal safety of the tested item based on the test results. The research results can provide safety indicators for the design, production, transportation, storage, and use of ammunition, fuel tanks, and other similar materials. The rapid combustion test simulates the most severe thermal environment that an object is in during an actual fire. It generally involves directly burning the test sample with an open flame in an oil bath, and the fuel is usually an organic fuel such as aviation kerosene.

[0003] Rapid combustion tests impose certain requirements on the fire environment. MIL-2105D specifies that the environment surrounding the test specimen must meet the following conditions: ① The ambient temperature around the test specimen must reach 550°C within 30 seconds of ignition; ② Heating of all parts of the test specimen must be uniform during the test, with an average temperature not lower than 800°C. This places certain demands on the design of the rapid combustion test apparatus. Currently, the commonly used oil bath fire test typically involves pre-digging a fixed oil bath according to the size of the test specimen and then artificially igniting it using torches or other means. For medium to large oil baths, this presents problems such as slow initial combustion rates, unstable combustion, and the possibility that the temperature may not reach 550°C within the specified 30 seconds. Furthermore, it can lead to uneven spatial temperature distribution in the initial stage of ignition and safety concerns. For a fixed oil bath, the biggest problem is that as the oil level drops during combustion, the heat transfer through the oil bath walls and changes in height cause variations in the temperature environment around the target, making it impossible to guarantee the stability and uniformity of the temperature environment around the test specimen throughout the test, which can negatively impact the test results. Furthermore, high temperatures place higher demands on the quality of the oil tank. Current solutions address this by using mechanical structures like buoyancy valves, which result in water injection only occurring when the liquid level has dropped to a certain height. This leads to low responsiveness, uneven temperature distribution within the oil tank, and damage to its structural integrity due to high temperatures. Frequent device replacements are often necessary because the oil-water mixture can easily cause the water below to boil due to heat conduction, leading to combustion instability and fuel splashing.

[0004] These problems result in low experimental precision, reduced reliability of test results, and significantly impact the reliability and accuracy of rapid combustion tests. Consequently, they lead to erroneous evaluations of subsequent processes such as transportation, storage, production, and use of flammable and explosive materials, severely affecting the results. Therefore, there is an urgent need for a more precise and practical device that can achieve remote ignition, uniform temperature distribution, even heating, stable combustion, and repeated durability. Summary of the Invention

[0005] In order to overcome the shortcomings and deficiencies of existing testing technologies, the purpose of this invention is to provide a multi-purpose rapid combustion test device.

[0006] To achieve the above technical solution, this invention application adopts the following technical solution:

[0007] A multi-purpose rapid combustion test device is disclosed, comprising four main parts: a remote synchronous ignition system, a liquid level self-balancing system, a real-time temperature and pressure monitoring system, and a fuel recovery system. It enables combustion tests on various types of projectiles, propellant charges, fuel tanks, batteries, etc., in an oil bath.

[0008] The remote synchronous ignition system includes an igniter and an ignition head, which can realize remote ignition and synchronous ignition, greatly increasing safety and reliability compared to previous ignition methods.

[0009] The self-balancing liquid level system includes a heated oil tank, a cooling tank, a liquid equalization plate, and an auxiliary water tank. The heated oil tank is placed on top of the cooling oil tank and connected by the liquid equalization plate. A balance leakage hole is provided between the cooling tank and the auxiliary water tank, which acts as a connector to maintain the water level in the cooling tank and the auxiliary water tank. This allows the water to automatically adjust according to changes in the liquid level, thus acting as a protective device to prevent high temperatures from damaging the device.

[0010] The real-time temperature and pressure monitoring system includes sensors on the oil tank and a central control and processing system. The sensors are temperature sensors, and pressure sensors are also installed on the oil tank for heating.

[0011] The fuel recovery system includes a recovery tank and an oil drain hole. Waste oil in the oil tank is guided into the recovery tank through a connecting pipe for subsequent processing. This device separates the heating and cooling protection, which is more conducive to protecting the device from deformation and damage caused by high temperatures. It also ensures real-time temperature monitoring during the heating process, ensuring uniform heating of the test sample. The device increases temperature and pressure monitoring and can analyze temperature and pressure data during rapid heating, allowing for real-time adjustment and greatly improving its practicality and reliability.

[0012] The multi-purpose rapid combustion test device is a foldable device. When the device is not in use, the legs can be folded, and the recovery tank and auxiliary water tank can be extended into the cooling tank. When the device is in use, the recovery tank and auxiliary water tank can be pulled out, and the legs can be raised. This design makes the whole device simple to operate and occupies little space.

[0013] In the remote synchronous ignition system, the ignition head is remotely connected to the igniter via an initiation wire, enabling remote and synchronous ignition without requiring close proximity to personnel. This significantly increases safety and reliability compared to previous ignition methods.

[0014] Furthermore, the ignition head is a chemical ignition source, with its main components being zirconium powder, barium nitrate, and barium peroxide mixed in a 4:3:3 ratio. 0.24 grams of this mixture can generate 1 kJ of energy.

[0015] Furthermore, the recovery tank is equipped with an oil leakage hole, a triangular brace, and folding legs. The folding legs at the bottom of the recovery tank have a groove to accommodate the legs after folding. The triangular brace is mainly for docking with the cooling tank when the recovery tank is folded and stretched. During the stretching process of the recovery tank, as the length is stretched, the triangular brace can be locked in the gap of the reserved expansion hole to ensure that the two tanks are fixed and sealed.

[0016] Furthermore, the oil drain hole is folded and sealed with a plug of appropriate size. At the end of each test, the oil in the recovery tank can be recovered through the oil drain hole for other uses.

[0017] Furthermore, folding support legs are installed in the grooves below the recycling tank and auxiliary water tank. When the entire device is placed, the support legs extend to fix the recycling tank and auxiliary water tank.

[0018] Furthermore, the liquid distribution plate is a tetrahedral perforated structure, with 14 liquid distribution plates vertically connected to the cooling pool. Water flows through the small holes of the liquid distribution plate, which can buffer the water temperature and indirectly cool it physically, greatly regulating the water temperature and providing stable support for the heating oil pool above.

[0019] Furthermore, the cooling pool serves to balance the temperature of the heating oil pool and protect the device from deformation due to excessively high temperatures, thereby improving the overall practicality and continuous use of the device.

[0020] Furthermore, the auxiliary water tank and the cooling tank are connected by a balance leakage hole, which acts as a connector to ensure that the liquid surface of the auxiliary water tank and the liquid surface of the cooling tank are kept at the same height. The balance leakage hole ensures that the liquid surface of the cooling tank is stable during the heating process, and the water supply rate is adjusted by pressure feedback through sensors and solenoid valves, so as to achieve real-time cooling.

[0021] Furthermore, the real-time temperature and pressure monitoring system consists of sensors on the fuel oil tank and a central control and processing system. The sensors detect the real-time temperature of the fuel oil in real time, which is beneficial for timely collection of temperature information.

[0022] Furthermore, the temperature sensor is a type K thermocouple, which is connected to the central control processor system via a data cable, and the real-time temperature is displayed online via a real-time temperature display.

[0023] Furthermore, pressure sensors are used to observe the thermal pressure generated during combustion during the baking process, monitor the system status in real time, and ensure the safety of the device.

[0024] The advantage of a fuel-fired heating pool is that it eliminates the need to add water to the bottom to protect the device; fuel can be poured in directly for heating and combustion, avoiding the risk of repeated ignition due to uneven oil-water mixing ratios.

[0025] This invention has significant advantages, specifically in the following aspects:

[0026] (1) Establish a multi-purpose rapid combustion test device with a wide range of applications. It can achieve remote ignition, balanced temperature, uniform heating, stable combustion, repeated durability, and is economical.

[0027] (2) This device adopts a retractable design, which greatly reduces the floor space required and can be used in various locations.

[0028] (3) This device has a separate design for heating and cooling, which solves the problems of boiling water below due to heat conduction, causing unstable combustion and fuel splashing, so that the temperature is balanced, the combustion is stable, and unnecessary errors are reduced; (4) This device uses an ignition head for remote ignition, which greatly improves the ignition efficiency and avoids the danger of manual ignition; (5) This device is equipped with a pressure and temperature detection system, which can detect the pressure and temperature in real time during the heating process and provide real-time data so that we can have a clearer understanding of the entire heating process;

[0029] (6) The cooling liquid level stabilization system of this device improves the stability of the environment in which the test target is in the combustion process by means of the communicating vessel principle between the cooling pool and the auxiliary oil pool. Attached Figure Description

[0039] The present invention will be further explained below with reference to specific embodiments.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a multi-purpose rapid combustion test device comprises four main parts: a remote synchronous ignition system, a liquid level self-balancing system, a real-time temperature and pressure monitoring system, and a fuel recovery system. This device can perform combustion tests on different types of projectiles, propellant charges, fuel tanks, batteries, etc. The remote synchronous ignition system includes an igniter 14 and an ignition head 15, enabling remote and synchronous ignition, significantly increasing safety and reliability compared to previous ignition methods.

[0041] The self-balancing liquid level system includes a heating oil tank 4, a cooling tank 8, a liquid equalization plate 1, and an auxiliary water tank 6. The heating oil tank 4 is placed on top of the cooling tank 8 and connected by the liquid equalization plate 1. A balance leakage hole 10 is provided between the cooling tank 8 and the auxiliary oil tank 6, which acts as a connector to maintain the water level in the cooling tank 8 and the auxiliary water tank 6, allowing the water to automatically adjust according to changes in the liquid level, thus protecting the device from damage caused by high temperatures. The real-time temperature and pressure monitoring system includes a sensor 9 on the oil tank and a central control and processing system 13. The sensor 9 is a temperature sensor, and the heating oil tank 4 is also equipped with a pressure sensor 12. The fuel recovery system includes a recovery tank 5 and a leakage hole 11. Waste oil in the heating oil tank 4 is guided into the recovery tank 5 through a connecting guide pipe for subsequent processing. This device separates the heating and cooling protection, which is more conducive to protecting the device from deformation and damage caused by high temperatures, and ensures real-time temperature monitoring during the heating process, ensuring uniform heating of the test sample. It increases temperature and pressure monitoring, and can analyze temperature and pressure data during rapid heating, allowing for real-time adjustment and greatly improving the practicality and reliability of the device.

[0042] During operation, this device utilizes the expansion of the left and right recovery tanks and the auxiliary oil tank 6, such as... Figure 5As shown, the test subject was placed in the center of the heating fuel oil tank 4 using a support. The oil leakage hole 11 of the heating fuel oil tank 4 was sealed. The heating fuel oil tank 4 was filled with fuel. The cooling tank 8 and auxiliary water tank 6 were filled with water up to 4 cm above the balance leakage hole 10. Temperature and pressure sensors were installed and connected to the central processing system 13 in the control room via data cables. Infrared and high-speed cameras were set up 10 meters away from the device for filming. The ignition head 15 was placed near the liquid surface of the heating fuel oil tank 4. The fuel in the heating fuel oil tank 4 was ignited by the remote igniter 14. Multiple test subjects were subjected to... During the rapid heating process, the cooling pool below the heating element experiences the highest temperature first, resulting in a faster drop in liquid level compared to the auxiliary water pool 6. The water flows through the balance leakage hole 10 to maintain a level liquid surface. Simultaneously, the flowing water passes through the small holes in the liquid equalization plate 1 to reduce the flow rate. The water also carries away some heat during its flow and dissipates heat more quickly through the liquid equalization plate 1, thus rapidly regulating temperature changes and maintaining the temperature stability of the heating process. After the experiment, the waste oil is connected to the recovery pool 5 through the oil leakage hole 11 and then returned to its original positions.

[0043] The multi-purpose rapid combustion test device is a foldable device. When the device is not in use, the support legs 2 can be folded, and the recovery tank 5 and auxiliary water tank 6 can be extended into the cooling tank. When the device is in use, the recovery tank 5 and auxiliary water tank 6 can be pulled out, and the support legs 2 can be raised. This design makes the whole device simple and easy to operate and occupies little space.

[0044] The remote synchronous ignition system consists of an igniter 14 and an ignition head 15. The ignition head 15 is remotely connected to the igniter via an initiation wire, enabling remote and synchronous ignition without requiring close proximity to personnel. This significantly increases safety and reliability compared to previous ignition methods.

[0045] The ignition head 15 is a chemical ignition source, mainly composed of zirconium powder, barium nitrate, and barium peroxide in a fixed ratio. 0.24 grams can generate 1 kJ of energy, and 2.4 grams can generate 10 kJ of energy to instantly ignite the combustion pool below.

[0046] The recovery tank 5 is equipped with an oil leakage hole 11, a triangular brace 7, and a folding support leg 3. The support leg at the bottom of the recovery tank 5 is provided with a groove so that the folding support leg 3 can be placed after the support leg is folded. The triangular brace is mainly for docking with the cooling tank 8 when the recovery tank 5 is stretched. During the stretching process of the recovery tank, as the length of the stretching increases, the triangular brace 7 can be locked in the gap of the reserved expansion hole to ensure that the two tanks are fixed and sealed.

[0047] The oil leakage hole 11 is sealed with a plug of appropriate size. After each test, the oil in the recovery tank 5 can be recovered through the oil leakage hole 11 for other uses.

[0048] The support leg 3 is set in the groove below the recovery tank 8 and the auxiliary oil tank 6. When the entire device is placed, the support leg extends to fix the recovery tank 8 and the auxiliary oil tank 6.

[0049] The liquid equalization plate 1 is a tetrahedral perforated structure. The 14 equalization plates are vertically connected to the cooling pool 8. The water flows through the small holes of the equalization plate, which can buffer the water temperature and indirectly cool it physically, greatly regulating the water temperature and providing stable support for the heating oil pool 4 above.

[0050] The cooling pool 8 serves to balance the temperature of the heating oil pool 4 and protect the device from deformation due to excessive temperature, thereby improving the overall practicality and continuous use of the device.

[0051] The auxiliary oil tank 6 and the cooling tank 8 are connected by a balance leakage hole 10, which acts as a connector. The liquid surface of the auxiliary oil tank 6 and the liquid surface of the cooling tank 8 are kept at the same height. The balance leakage hole 10 ensures that the liquid surface of the cooling tank is stable during the heating process. The pressure sensor 9 and the solenoid valve form pressure feedback to adjust the water supply rate, thereby achieving real-time cooling.

[0052] The real-time temperature and pressure monitoring system includes a sensor 9 on the oil tank and a central control and processing system 13. The temperature sensor 9 detects the real-time temperature of the combustion process, which is beneficial for timely collection of temperature information. The central control system 13 includes a digital acquisition unit, an amplifier, and a computer. It is connected to the temperature sensor 9 and the pressure sensor 23 on the device. The amplifier amplifies the signal, and the digital acquisition unit collects the signal to the computer terminal for processing.

[0053] The temperature sensor is a type K thermocouple, which is connected to the central control processor system via a data cable, and the real-time temperature is displayed online in real time via a real-time temperature display.

[0054] The advantage of the 4-fuel-baking pool compared to other fuel-baking pools is that it does not require adding water to the bottom to protect the device. Fuel can be poured in directly for baking and combustion, avoiding the risk of repeated ignition due to uneven oil-water mixing ratio.

[0055] The multi-purpose rapid combustion test device discloses a multi-functional and multi-purpose combustion method that can achieve automatic ignition, real-time temperature control, and rapid combustion protection. It overcomes the shortcomings of existing devices, such as single function, uneven combustion temperature, and safety accidents caused by manual ignition, thus solving some technical difficulties. The specific method is as follows:

[0056] Composed of four main parts—a remote synchronous ignition system, a liquid level self-balancing system, a real-time temperature and pressure monitoring system, and a fuel recovery system—this system can perform oil bath combustion tests on different types of projectiles, propellant grains, fuel tanks, batteries, etc. It can be applied to combustion-related tests in different fields and has comprehensive functions.

[0057] The liquid level self-balancing system is designed with a liquid equalization plate for connection. A balance leakage hole is provided between the cooling tank and the auxiliary oil tank, which acts as a connector to maintain the water level in the cooling tank and the auxiliary water tank. This allows the water to automatically adjust according to the changes in liquid level, and also serves as a protective device to prevent high temperature from damaging the device. It can achieve temperature self-control and the function of a protective device.

[0058] The designed real-time temperature and pressure monitoring system can detect changes in the temperature of the oven in real time and make adjustments accordingly.

[0059] By using the above methods, and further supplemented by external high-speed cameras and infrared lamps, it is possible to monitor the combustion situation in real time and control the combustion state.

[0060] The cooling liquid level stabilization system of this invention improves the stability of the environment during the combustion process of the test target by using the communicating vessel principle between the cooling pool and the auxiliary oil pool. The ignition electrode on the device is used to ignite multiphase cloud fuel and is easy to disassemble, so that the experiment is not limited by the site. The pressure sensor is used to collect the explosion pressure after the explosion. The vacuum pump is used to evacuate the tank before the experiment. The pressure gauge is used to monitor the vacuum level inside the tank. The control and processing system and the data acquisition system are integrated together, which greatly facilitates the experimental process.

[0061] Example 1

[0062] A rapid combustion test was conducted on a cylindrical-rectangular oil drum measuring 76mm in length and 45mm in width, at a height of 1 meter. The combustion oil tank measured 1.8m x 0.9m, and aviation kerosene JP-5 was used as fuel. Before the test, the test object was fixed above the combustion oil tank, and temperature and pressure sensors were fixed in their respective positions within the combustion oil tank. Before the test began, fuel was injected into the combustion oil tank, and water was added to the cooling tank and auxiliary oil tank until it reached 4cm above the balance leakage hole. Temperature and pressure sensors were installed and connected to the central processing system in the control room via data cables. Infrared and high-speed cameras were set up 10 meters away from the device for recording. The ignition head was placed near the liquid surface in the combustion oil tank, and the fuel in the combustion oil tank was ignited by a remote igniter. During the combustion process, temperature and pressure sensors monitor and record the combustion pressure and temperature in real time. Infrared and high-speed cameras capture the reaction phenomena. After observing the reaction, the system is shut down. Once the combustion oil pool cools, the drain hole is opened, and waste oil is recycled to an auxiliary oil pool via a conduit for secondary cooling. The waste oil is then recycled again through the drain hole of the auxiliary oil pool. After the experiment, reaction debris at the reaction site is photographed and recorded for analysis of the reaction type. Simultaneously, temperature data recorded by thermocouples is recorded and saved for subsequent experimental simulations or data processing. Through the regulation of the above device, the temperature balance during combustion can be acquired, allowing the temperature to remain within the controlled range, achieving continuous constant-temperature combustion and significantly improving combustion efficiency. Specific effects are as follows: Figure 7 , Figure 8 .

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
