Description

Technical Field

[0001] The present invention relates to the technical field of multi-parameter verification of slurry, and more particularly, to a multi-parameter verification device and a usage method for propellant slurry. Background Art

[0002] The casting process of composite propellant is relatively complex, and the requirements for each process such as process, materials, equipment, and personnel are different. In addition, due to industry barriers, advanced civilian technologies cannot be introduced, and relevant materials cannot be made public for the need of confidentiality, which results in the inability to share the research content of each propellant manufacturer. The standards for process parameter experiments in the casting process of propellant slurry have not been established. When conducting research, each manufacturer mainly designs experimental devices according to their own needs, with a high degree of non-standard customization and strong specialization of each experimental device, and a general-purpose multi-parameter verification experimental device has not been formed. The casting of propellant slurry is a very critical process in the production process of propellants, which will directly affect the final state of the propellants. At present, the methods for studying the flow field structure change and process parameters in the vacuum casting process of propellants mainly include simulation and experiment. The simulation method can analyze the parameter details in the propellant casting process, which is convenient for optimizing the casting process. However, due to the influence of factors such as simulation models, simulation environments, and propellant composition deviations during simulation, it is difficult to simulate the real situation of propellant flow, usually with large deviations. When actually used, the trend of simulation is generally adopted, and the simulated values are only for reference by experimental personnel. In order to accurately obtain the flow characteristics of the propellant and continuously improve the simulation process, the experimental method is essential. Propellant slurries all belong to energetic materials. During experiments, it is necessary to find the threshold of a certain parameter, which requires at least reaching the damage point of the propellant during the experiment, and the equivalent risk during production is relatively high. Generally, small-equivalent propellant slurries are used for experiments to ensure safety.

[0003] The existing technologies mainly conduct relevant test detections for a certain parameter and do not achieve high flexibility. Therefore, there is an urgent need for a device that can conduct relevant test detections on multiple parameters. Summary of the Invention

[0045] The casting process of composite propellants is relatively complex, and the requirements for each process such as technology, materials, equipment, and personnel are different. In addition, due to industry barriers, advanced civilian technologies cannot be introduced, and relevant materials cannot be made public for confidentiality reasons, which results in the inability to share the research content among propellant manufacturers. There is no established standard for the process parameter experiments during the casting process of propellant slurries. When conducting research, each manufacturer mainly designs experimental devices according to their own needs, with a high degree of non-standard customization and strong specialization of each experimental device, and no general-purpose experimental device for multi-parameter verification has been formed. The casting of propellant slurries is a crucial process in the production of propellants and will directly affect the final state of the propellants. Currently, the main methods for studying the flow field structure changes and process parameters during the vacuum casting process of propellants are simulation and experiment. The simulation method can analyze the parameter details during the slurry casting process and is convenient for optimizing the casting process. However, due to the influence of factors such as simulation models, simulation environments, and slurry composition deviations during simulation, it is difficult to simulate the real situation of slurry flow, usually with large deviations. In actual use, the general trend of the simulation is usually adopted, and the simulated values are only for reference by experimental personnel. In order to accurately obtain the flow characteristics of the slurry and continuously improve the simulation process, the experimental method is essential. Propellant slurries are all energetic materials. During experiments, the threshold of a certain parameter needs to be found, which requires at least reaching the damage point of the propellant during the experiment. The risk of using the equivalent amount during production is relatively high, and generally, small-equivalent slurries are used for experiments to ensure safety.

[0046] The related technologies mainly conduct relevant test detections for a certain parameter and do not achieve high flexibility. Therefore, there is an urgent need for a device that can conduct relevant test detections for multiple parameters.

[0047] Please refer to Figures 1-4 , this embodiment provides a multi-parameter verification device and usage method for propellant slurries, which can effectively improve the above-mentioned technical problems, can conduct test verifications for multiple parameters, and is efficient and convenient to use.

[0048] Please refer to Figures 1-4, the multi-parameter verification device for propellant slurry includes a multi-parameter experimental device 10, an infrared thermal imager 20, a mold temperature controller 30, and an air compressor 40. The multi-parameter experimental device 10 is used to load the slurry.

The first workbench 80 and the second workbench 90 are respectively arranged on both sides of the partition wall 100. The multi-parameter experimental device 10, the air compressor 40, the mold temperature controller 30, and the infrared thermal imager 20 are all installed on the first workbench 80, and the control module 70 is installed on the second workbench 90. The control module 70 is simultaneously connected to the multi-parameter experimental device 10 and the air compressor 40.

The operator can achieve the isolation effect through the partition wall 100, ensuring the safety of personnel during use.

[0050] Further, the control module 70 controls the multi-parameter experimental device 10 and the air compressor 40 through a connection accessory 200. Specifically, the connection accessory 200 includes a manual rotary valve and a controllable pressure regulating gauge.

[0051] Specifically, the infrared thermal imager 20 and the multi-parameter experimental device 10 are arranged at intervals, and the infrared thermal imager 20 is detachably installed on the tabletop of the first workbench 80. The infrared thermal imager 20 can detect the temperature change of the multi-parameter experimental device 10 in real time and generate a temperature change curve.

The air compressor 40 is arranged on the other side of the first workbench 80, and the air compressor 40 can pressurize the slurry in the multi-parameter experimental device 10.

[0052] In this embodiment, the multi-parameter experimental device 10 includes a cartridge column 11, a pressing member 12, and an air flow baffle 13.

The pressing member 12 is arranged at the bottom of the cartridge column 11 and presses the discharge pipe 15. The air flow baffle 13 is installed at the top of the cartridge column 11. Among them, the air flow baffle 13 can seal the top of the cartridge column 11. The air flow baffle 13 and the top of the cartridge column 11 are sealed by a locking cap 14. The locking cap 14 can block the slurry, thereby providing a closed space for the cartridge column 11. The air flow baffle 13 can play a role in gas diversion to prevent the slurry from forming a vortex when pressurized. The discharge pipe 15 is of a hose structure. The pressing member 12 is a pressing cylinder, and the cartridge column 11 is pressed or loosened by the pressing cylinder, so as to realize the closing and flowing of the slurry.

[0053] During use, first press the pressing cylinder through a manual rotary valve, remove the locking cap 14 and the air flow baffle 13, load the slurry into the cartridge column 11, then install the air flow baffle 13, and then install the locking cap 14. Reach the set pressure by adjusting the controllable pressure regulating meter, and open the pressing cylinder through the manual rotary valve. The slurry in the cartridge column 11 flows out through the discharge pipe 15.

[0054] Furthermore, the multi-parameter experimental device 10 further includes a medicine receiving tray 50, a weighing member 60, and a pressing plate 16. The medicine receiving tray 50 is arranged at the bottom of the discharge pipe 15 and is used to receive the slurry flowing out of the discharge pipe 15.

Among them, the number of pressing plates 16 is three, and the three pressing plates 16 are arranged at intervals in the vertical direction. The medicine receiving tray 50 and the weighing member 60 are arranged on the lowermost pressing plate 16. The cartridge column 11 and the pressing member 12 are arranged on the middle pressing plate 16. The air flow baffle 13 and the locking cap 14 are arranged on the uppermost pressing plate 16.

The main body 111 is used to load the slurry. The water jacket layer 112 is arranged outside the main body 111. The contraction part 113 communicates with the bottom end of the main body 111. The pipe joint 115 communicates with both the contraction part 113 and the discharge pipe 15 at the same time. The threaded part 114 is arranged at the top end of the main body 111, and the threaded part 114 is threadedly connected to the air flow baffle 13.

[0057] Specifically, the threaded portion 114 has an external thread, and the threaded portion 114 is threadedly connected to the bottom of the air flow baffle 13, thereby connecting the air flow baffle 13 and the body 111 to ensure stability during use. The contraction portion 113 is a frustum structure, and the top diameter of the contraction portion 113 is larger than the bottom diameter of the contraction portion 113.

[0058] In this embodiment, the water jacket layer 112 is a hollow structure, and the water jacket layer 112 is communicated with the mold temperature machine 30.

Among them, a water pipe 1121 is communicated with the water jacket layer 112, and the water pipe 1121 is externally connected to the mold temperature machine 30. The hot water in the mold temperature machine 30 enters the water jacket layer 112 via the water pipe 1121, thereby heating the slurry in the body 111.

[0059] Specifically, the number of the water pipes 1121 is two. One water pipe 1121 is used to inject hot water into the water jacket layer 112, and one water pipe 1121 is used to discharge hot water, thereby realizing the heat cycle inside the water jacket layer 112.
