Technical Field

[0001] The present application relates to the field of laser ignition technology, and in particular to an automatic continuous ignition and combustion experimental device for polymorphic metal energetic materials. Background Art

[0002] Solid fuel powders, such as boron and aluminum, have a wide range of applications due to their very high mass and volume calorific values. The redox reaction between the elemental aluminum and a mixture of less reactive metal oxides is called the thermite reaction. While the thermite reaction rapidly releases enormous amounts of chemical heat, it holds potential scientific value in areas such as metal welding, energetic explosives, and microsatellite propulsion, but it also carries certain safety risks.

[0003] Chinese Patent No. 202211252165.9, filed on October 13, 2022, is titled "A Sample Stage Suitable for Laser Ignition of Single Particles of Energetic Materials and Its Application." The invention discloses a sample stage suitable for laser ignition of single particles of energetic materials and its application. The sample stage comprises a glass slide with a plurality of micropores disposed thereon. The micropores have a certain depth but do not extend through the thickness of the glass slide. The diameter of the micropores matches the diameter of the sample particles, so that at least one sample particle can be trapped in at least one micropore. Compared with ordinary glass slides, the sample stage of the present invention can effectively restrain single particles of energetic material, preventing positional deviation caused by decomposition and gas release of the single particle of energetic material under the action of the laser beam, thereby achieving laser ignition of the single particle of energetic material, and enabling analysis of the combustion process of the single particle of energetic material and microstructural observation and chemical composition analysis of the specific location of the combustion products corresponding to the particle. However, the sample stage can only realize the combustion of single particles of energetic material and cannot study the combustion of powder accumulation and bulk energetic materials.

Summary of the Invention

[0006] The technical problem addressed by this invention is to overcome the limited experimental applicability of existing laser ignition devices and the lack of representativeness of powder ignition. This invention provides an automated, continuous laser ignition and combustion analysis experimental apparatus for metallic polymorphic energetic materials. This apparatus features both single-particle ignition and compressed pellet ignition, similar to the state of a reagent solid propellant. Compared to powder ignition, compressed pellet ignition is more representative of the state of the sample in actual solid propellant applications. Single-particle ignition also allows for better analysis of the sample's combustion mechanism.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: The invention discloses an automatic continuous laser ignition combustion analysis experimental device for metal polymorphic energetic materials, comprising a gas supply system, a combustion system, an automatic feeding system, a sample dispersion system, a sample tablet pressing system and a combustion data acquisition system.

Fuel burns on the quartz plate. The quartz cover, positioned above the combustion platform to maintain atmosphere, is transparent and facilitates observation and data collection. A hole is provided on its top for laser access. The quartz plate is moved along a conveyor belt beneath the laser for ignition experiments.

[0010] As a preferred embodiment of the automatic continuous laser ignition combustion analysis experimental device for metal polymorphic energetic materials described in the present invention, the automatic loading system includes a loader and a transmission system, wherein the loader is composed of a storage bin, a rotating shaft, a first distribution plate, a distribution bin, a second distribution plate and a discharge bin from top to bottom, the storage bin is installed above the distribution bin and is fixedly connected to the distribution bin, and a feeding hole is left above the storage bin. The first distribution plate is fixedly connected to the storage bin, the rotating shaft is fixedly connected to the distribution bin, and a feeding hole is left on the first distribution plate. The distribution bin rotates with the rotating shaft. When the feeding hole on the first distribution plate coincides with the feeding hole in the distribution bin, the sample falls into the feeding hole and rotates with it. When the feeding hole containing the sample coincides with the feeding hole on the second distribution plate, the sample falls into the discharge bin and is placed on the quartz plate through the feeding hole. The rotation of the rotating shaft is controlled by an electrical signal, thereby realizing the continuous addition of samples and the continuous conduct of the experiment. After unloading, the quartz plate will be pushed onto the conveyor belt by the push rod, and will be transported to the bottom of the laser hole along the conveyor belt. The laser will enter from the hole and hit the sample.

At the same time, multi-mode experiments can also be carried out to collect combustion data of samples under different states.

[0012] The above technical solution uses a storage bin and four storage holes for continuous operation. When the drop holes on the first distribution plate coincide with the storage holes in the distribution bin, the sample will fall from the storage bin into the storage holes. The storage holes are filled with the samples required for a single experiment. As the shaft rotates, when the storage holes coincide with the drop holes of the second distribution disc, the sample falls into the discharge bin and is placed on the quartz plate through the discharge holes. It is then pushed to the bottom of the sample dispersion system or the sample pressing system by a push rod. An electrical signal controls whether to process it into single particles or blocks for testing. Finally, it is moved to the bottom of the laser through a conveyor device for ignition. This solution controls each system through electrical signals, realizes multi-module ignition experiments, and can perform continuous experiments.

When the sample is placed on a single-particle quartz plate by an automatic loading system, an electrical signal controls the disperser to disperse the sample on the quartz plate, dispersing the particles into tiny holes on the quartz plate. The particles are then sent to the bottom of the laser ignition through a transmission system for ignition and combustion.

[0017] As a preferred embodiment of the present invention's automated continuous laser ignition combustion analysis experimental apparatus for metallic polymorphic energetic materials, the sample pressing system is operated by a tablet press. When the sample is placed onto the pressing quartz plate by the automatic loading system, an electrical signal controls the tablet press to compact the sample within the quartz plate's holes, ensuring that all holes are centered.

These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention, and directions and references may be used only to facilitate the description of features in the drawings. Therefore, the following detailed description is not to be taken in a limiting sense, and the scope of the claimed subject matter is limited solely by the appended claims and their equivalents.

[0024] Example: Figure 1-9 As shown, the present invention provides an automatic continuous laser ignition combustion analysis experimental device for metal polymorphic energetic materials, including a gas supply system 100, a combustion system 200, an automatic loading system 300, a sample dispersion system 400, a sample pressing system 500 and a combustion data acquisition system 600.

The gas inlet pipe 102 is connected to the output end of the gas tank 101, and the other end extends into the interior of the transparent quartz cover 203. A mass flowmeter and a flowmeter controller are installed at the output end of the gas tank 101. When the valve of the gas tank 101 is opened, gas at a set flow rate is input through the mass flowmeter to fill the transparent quartz cover 203.

[0026] The combustion system 2 includes a quartz plate 201, a combustion platform 202, and a transparent quartz cover 203. The combustion platform 202 is used to assemble the various system modules. The quartz plates 201 are divided into two types: single-grain quartz plates 2011 and pressed quartz plates 2012. The sample is ignited and burned on the quartz plate 201. The quartz plate 201 is placed on a push rod for loading. After loading, the push rod pushes the quartz plate 201 to the starting end of the conveyor belt. The transparent quartz cover 203 is placed above the combustion platform 202 to maintain the atmosphere. Its transparent material facilitates data collection by the combustion data acquisition system 6.

[0027] The automatic feeding system 3 includes a loader 301 and a transmission system 302. The loader 301 comprises, from top to bottom, a storage bin 3011, a rotating shaft 3012, a first distribution tray 3013, a distribution bin 3014, a second distribution tray 3015, and a discharge bin 3016. The storage bin 3011 is mounted above and fixedly connected to the distribution bin 3014, and a feeding hole is provided above the storage bin 3011. The rotating shaft 3012 is fixedly connected to the distribution bin 3014, and the distribution bin 3014 rotates with the rotating shaft 3012.

The first distribution tray 3013 has a feeding hole and a rotating shaft hole, and the distribution bin 3014 has four distribution bin holes. When the drop hole on the first material distribution plate 3013 coincides with the storage hole in the material distribution bin 3014, the sample will fall from the storage bin 3011 into the storage hole in the material distribution bin 3014. The storage hole is filled with the sample required for a single experiment. As the rotating shaft 3012 rotates, when the storage hole coincides with the drop hole of the second material distribution plate 3015, the sample falls into the discharge bin 3016 and is placed on the quartz plate 201 through the discharge hole, and then pushed to the bottom of the sample dispersion system or the sample pressing system by the push rod.

[0028] The transmission system consists of three conveyor belts and three push rods, each corresponding to a specific location. The first and second push rods push the quartz plate with the sample onto the first and second conveyor belts. After processing, the conveyor belt transports the quartz plate to the center of the combustion table. The third push rod then pushes the plate onto the third conveyor belt, where it moves to the bottom of the laser for ignition. The sample dispersion system and sample tableting system are placed on the first and second conveyor belts, respectively, to facilitate processing.

[0029] The disperser 401 in the sample dispersion system 4 performs sample dispersion work. The disperser 401 is installed at the starting end of the conveyor belt 1. After the sample is placed on the single-particle quartz plate 2011 by the automatic loading system 3, the push rod starts working to push the quartz plate to the starting end of the conveyor belt. Then, the electrical signal controls the disperser 401 to work, disperse the sample on the quartz plate 2011, and disperse the particles into the tiny holes on the quartz plate 2011. The particles are then sent to the bottom of the laser ignition through the transmission system 302 for ignition and combustion.

[0030] The tablet press 501 in the sample pressing system 5 performs sample pressing. The tablet press 501 is installed at the starting end of the conveyor belt 2. When the sample is placed on the pressing quartz plate 2012 by the automatic loading system 3, the push rod starts working to push the quartz plate to the starting end of the conveyor belt. Then the electrical signal controls the tablet press 501 to work and compact the sample in the hole of the quartz plate 2012. After that, the electrical signal controls the operation of the conveyor belt to transport the quartz plate 2012 to the bottom of the laser ignition for ignition and combustion experiment.

After the mode is selected, the corresponding module starts working. Taking the tablet pressing mode as an example, after selecting the tablet pressing mode, the automatic loader 301 of the tablet pressing part starts working, and the sample is placed in the hole on the tablet pressing quartz plate 2012. The push rod 3026 then pushes the quartz plate 2012 to the starting end of the corresponding conveyor belt 3025. The tablet press 501 starts working, the pressure head extends, and the sample in the corresponding hole is compacted. Then the conveyor belt 3023 starts and conveys the quartz plate 2012 to the bottom of the laser ignition.

[0034] 3. Ignition and combustion: After pre-setting the emission power and emission time of the laser igniter, when the quartz plate 2012 with the sample installed moves to the bottom of the igniter, the laser igniter is started, and the laser is emitted from the laser emission head, passes through the laser hole 2031 reserved on the quartz cover 203, and hits the fuel on the quartz plate 2012 to ignite and burn.

[0035] 4. Combustion data acquisition: The laser igniter emits a laser and simultaneously sends a voltage signal to the integrated controller 604. The fiber optic spectrometer 602 begins to collect the characteristic spectrum of the sample combustion. The high-speed camera 601 begins to record the entire combustion process inside the transparent quartz cover 203 and transmits the video in real time to the computer 603. The computer 603 saves the recorded fiber optic spectrum data for subsequent combustion data analysis.
