Description

Technical Field

[0001] This invention belongs to the field of charge and solidification technology of cast explosives, specifically relating to a multi-station continuous charge device and method for cast explosives. Background Technology

[0002] Fused cast explosives are mixed explosives with a low-melting-point carrier as the liquid phase and high-energy explosive particles such as RDX, HMX, and CL-20 as the solid phase. In the research, development, iterative upgrades, and application of fused cast explosives, in addition to designing explosive components to reduce susceptibility and improve destructive performance, it is also necessary to optimize the fused cast explosive preparation process and mixing and molding equipment. Currently, in the actual charge solidification process, the mixing steps include premixing and subsequent kneading, with the melting and mixing time for a single batch of fused cast explosives exceeding 90 minutes. The process involves many steps and requires many on-site operators. The melting, charging, solidification, and transfer processes require interconnected transfer links, making continuous operation impossible. This results in low efficiency, high cost, poor mixing and solidification quality, and the inability to achieve continuous production of fused cast explosives, severely restricting the safe supply capacity of high-energy fused cast explosives. Consequently, it is difficult to meet the demand for efficient and large-scale production of fused cast explosives and warhead charges. Therefore, acoustic resonance mixing technology has been widely applied to in-situ mixing and solidification of warheads in the past decade or so. However, this process is suitable for a single product and is difficult to implement in multi-station continuous production.

[0049] This embodiment discloses a multi-station continuous charging device for molten explosives, such as... Figure 1 and Figure 2 As shown, the device includes a base 1, and several vibrating blocks 2 are arranged below the base 1;

[0050] The base 1 is provided with a track unit 3, and four water bath jackets 4 are equally spaced on the track unit 3.

The position on the annular track 301 of the water bath jacket 4 is the solidification station.

[0051] The base 1 is also provided with a support vibration transmission frame 6, on which a melting pot 7 is mounted. The melting pot 7 can be clamped and fixed on the support vibration transmission frame 6. A pressure regulating unit 8 is connected to the melting pot 7. The pressure regulating unit 8 includes a sealing cover 801 that can match the melting pot 7 and a melting pot pressure regulating pipe 802 connected to the sealing cover 801.

[0052] The bottom of the melting pot 7 is provided with an explosive casting port 703. The melting pot 7 can melt the explosive components added to the melting pot according to the preset temperature and vacuum degree to obtain a mixed explosive melt, and then fill the obtained mixed explosive melt into the projectile mold 5 that moves along the track unit 3 to the bottom of the melting pot 7.

[0053] Preferably, in this embodiment, a total of five vibration blocks 2 are arranged below the base 1. One of the five vibration blocks 2 is located directly below the middle of the supporting vibration transmission frame 6, and the other four vibration blocks 2 are located directly below the four water bath jackets 4.

[0061] Example 2

[0062] This embodiment discloses a multi-station continuous charging method for cast explosives, which is implemented using the multi-station continuous charging device for cast explosives provided in Embodiment 1, and includes the following steps:

[0063] Step 1: Open the sealing cover 801, add the prescribed amount of solid explosive and carrier explosive into the melting pot 7, and close the sealing cover 801.

[0064] Step 2: Start the vacuum pump and adjust the pressure inside the melting pot 7 to 15-40 Pa. The vacuum pump can create a negative pressure environment inside the melting pot 7, which is conducive to the discharge of gas from the suspended explosive.

[0065] Step 3: Set the temperature of the hot oil injected into the oil passage according to the melting point of the solid explosive carrier; set the first preset value of the acceleration of the vibrating block 2. Preferably, the first preset value is 25-35g, where g is the acceleration due to gravity, g≈9.80m / s². 2 Start the vibrating block 2. Under the vibration of the vibrating block 2, the carrier explosive and solid explosive in the melting pot 7 can be better mixed and melted. After the carrier explosive melts, adjust the acceleration of the vibrating block 2 to the second preset value. Preferably, the second preset value is 50-60g. After cooling by 5-10℃, vibrate for 30-40 minutes to obtain the mixed explosive melt.

[0066] Step 4: Preheat the projectile mold 5 with the help of the water bath jacket 4 until the temperature of the projectile mold 5 is 5-15°C higher than the temperature of the melting pot 7.

[0067] According to experimental measurements, after preheating, the temperature dissipation of the projectile mold 5 during the entire injection process is 5-15℃. Therefore, by using the water bath jacket 4 to preheat the projectile mold 5 so that its temperature is 5-15℃ higher than that of the melting pot 7, it can be ensured that the temperature of the projectile mold 5 is close to the temperature of the mixed explosive melt in the melting pot 7 during the casting process, thereby ensuring that the temperature of the mixed explosive melt is close to that of the projectile mold 5 after the injection is completed.

[0068] Step 5: Using a power mechanism, a projectile mold 5 is moved along a linear track 302 to below the explosive casting port 703;

[0069] Step 6: Backfill the molten explosive pot 7 with high-pressure inert gas until the internal pressure is 0.4-0.8 MPa. During the charging stage of the cast explosive, increasing the pressure inside the molten explosive pot is beneficial for the molten explosive to be discharged from the charging port. Fill the projectile mold 5 with the mixed explosive melt. After the mixed explosive melt is filled, the projectile mold 5 returns to the water bath jacket 4 via the track unit 3 and undergoes cooling and heat preservation treatment until the cast explosive melt is completely solidified.

[0070] As a preferred embodiment, when filling the projectile mold 5 with the mixed explosive melt, the filling speed is 1-3 L / min, the single filling time is 1-3 min, the cooling time is 90-120 min, and the holding time is 30-50 min.

[0071] Step 7: Repeat steps 5 and 6 until the molten explosive in all the elastic modulus 5 has completely solidified. The elastic modulus 5 are then moved sequentially through the projectile's straight track 303 to the explosion-proof isolation wall 10.

[0072] Application Example 1

[0073] This application example uses the apparatus disclosed in Example 1 and the method disclosed in Example 2 to complete the mixing and solidification of TNT / RDX molten casting explosive, specifically including:

[0074] Equipment preparation: Install the complete set of equipment, ensuring that the four water bath jackets and the projectile mold set in the water bath jackets are all in place, the pressure regulating unit and the injection flow regulator are installed in place, and the air circuit of the vacuum pump and the oil circuit of the melting pot are installed in place.

[0075] Explosive preparation: Based on the TNT / RDX (40 / 60) composition of the cast explosive and the dimensions of the explosive charge and riser, calculate the total amount of explosive required for the projectile mold and half the riser volume, as well as the proportion of each component.

[0076] Feeding and Vacuuming: Open the sealed lid and add the prescribed amounts of solid explosive and carrier explosive into the melting pot, then close the sealed lid. Use the remote controller to turn on the vacuum pump and pipeline valves to begin vacuuming. After about 5 minutes, the pressure thermometer will show that the pressure inside the melting pot reaches 25 Pa. Then close the valves.

[0077] Melting and mixing: Set the oil bath temperature to 98℃ and start melting the carrier explosive in the melting pot. Set the acceleration of the vibrating block to 30g. After the carrier explosive is completely melted after 15 minutes, adjust the acceleration of the vibrating block to 55g and cool it down to 88℃. Continue vibrating for 30 minutes to obtain the mixed explosive melt.

[0078] Preheating the projectile mold: Turn on the mold temperature controller, set the water temperature of the mold temperature controller to 98℃, and use the water bath jacket to preheat the projectile mold to about 98℃ and keep it at that temperature.

[0079] Explosive loading: Open the water bath jacket and use the power mechanism to move a projectile mold to below the explosive casting port; backfill the molten charge pot with high-pressure inert gas until the internal pressure is 0.4-0.8 MPa; fill the projectile mold with mixed explosive melt, and set the injection rate to 1 L / min and the injection time to 3 min per injection, according to the projectile size.

[0080] Solidification Care: After the projectile mold is filled with the mixed explosive melt, it returns to the water bath jacket via the track unit. The water bath cooling rate is set to 1℃ / min, and the projectile mold is cooled uniformly for 90 minutes until the explosive is completely solidified and cooled to room temperature of 20℃. After holding at this temperature for 10 minutes, the mold temperature controller is turned off.

[0081] Projectile Removal: Repeat the above steps until the molten explosive in all the elastic molds has completely solidified. The elastic molds are then moved sequentially along the projectile removal track to the explosion-proof isolation wall. This completes the removal of the elastic molds and the reshaping of the explosive charge.

[0082] Finally, clean the melting pot in preparation for the next test and production.

[0083] In this application example, the final propellant column had no defects visible to the naked eye. After testing, the propellant column showed excellent solidification quality and high molding density.

[0088] Explosive preparation: Based on the composition of the cast explosive TNT / DNAN / HMX (10.5 / 24.5 / 65) and the dimensions of the explosive charge and riser, calculate the total amount of explosive required for the projectile mold and half the volume of the riser, as well as the proportion of each component.

[0089] Feeding and Vacuuming: Open the sealed cover and add the prescribed amounts of solid explosive and carrier explosive into the melting pot, then close the sealed cover. Use the remote controller to turn on the vacuum pump and pipeline valves to begin vacuuming. After about 8 minutes, the pressure gauge will show an internal pressure of 18 Pa in the melting pot. At this point, close the pipeline valves.

[0090] Melting and mixing: Set the oil bath temperature to 105℃ and start melting the carrier explosive in the melting pot. Set the vibration block acceleration to 35g. After the carrier explosive is completely melted after 12 minutes, increase the vibration acceleration of the vibration block to 55g and decrease the melting pot temperature to 80℃. Continue vibration for 30 minutes to obtain the mixed explosive melt.

[0091] Preheating the projectile mold: Turn on the mold temperature controller and set the water temperature of the mold temperature controller to 93℃. Use the water bath jacket to preheat the projectile mold to about 93℃ and keep it at that temperature.

[0092] Explosive loading: Sequentially open the water bath jacket, and the projectile mold is quickly moved to the center position below the molten charge pot. At this time, high-pressure inert gas is backfilled into the molten charge pot until the internal pressure reaches 0.6 MPa. Open the injection valve and flow control monitor, and fill the projectile mold with the mixed explosive melt. Set the injection rate to 1.2 L / min according to the projectile size, and the injection time for each injection is 3 min.

[0093] Solidification treatment: After the projectile mold is filled with the mixed explosive melt, it returns to the water bath jacket via the track unit. The mold temperature controller is set to cool the projectile mold at a water bath cooling rate of 1℃ / min. After cooling to 60℃, it is held for 10 minutes. Then, it is cooled to room temperature (20℃) at a cooling rate of 1℃ / min and held for another 10 minutes. The entire solidification treatment time is about 88 minutes. Then the mold temperature controller is turned off.

[0094] Projectile Removal: Repeat the above steps until the molten explosive in all elastic molds has completely solidified. The elastic molds are then moved sequentially along the projectile removal track to the explosion-proof isolation wall. Subsequent operations, such as mold removal and explosive charge shaping, are then completed. Finally, the molten explosive pot is cleaned in preparation for the next test and production.

[0095] In this application example, the final prepared propellant column had no pores or cracks inside, and the solidification quality was high.

A method of casting multiple charges of melt-cast explosive, the method comprising: The method is implemented using the multi-station continuous charging device for cast explosives as described in any one of claims 1 to 7, and includes the following steps: Step 1: Open the sealed lid, add the prescribed amount of solid explosive and carrier explosive into the melting pot, and close the sealed lid; Step 2: Start the vacuum pump and adjust the pressure inside the melting pot to 15~40Pa; Step 3: Set the temperature of the hot oil injected into the oil cavity according to the melting point of the solid explosive carrier; set the first preset value of the vibration block acceleration and start the vibration block; after the carrier explosive melts, adjust the vibration block acceleration to the second preset value, cool it down by 5~10℃ and vibrate for 30~40 minutes to obtain the mixed explosive melt. Step 4: Preheat the projectile mold using a water bath jacket until the temperature of the projectile mold is 5-15°C higher than the temperature of the melting pot. Step 5: Using a power mechanism, move a projectile mold to below the explosive casting port; Step 6: Backfill the melting pot with high-pressure inert gas until the internal pressure is 0.4~0.8MPa; inject molten explosive into the projectile mold; after the projectile mold is filled, return to the water bath jacket through the track unit for cooling and heat preservation treatment until the molten explosive is completely solidified. Step 7: Repeat steps 5 and 6 until the molten explosive in all the elastic molds is completely solidified. The elastic molds are then moved sequentially along the projectile track to the explosion-proof isolation wall. The first preset value is 25~35g, and the second preset value is 50~60g, where g is the gravitational acceleration, with a value of 9.80m / s².
