Description

Technical Field

[0001] The present invention relates to the technical field of cast charge, and particularly to a pulse distributed cast charge mixing system. Background Art

[0002] Cast charge is a molding method in which a low-melting-point carrier explosive is heated and melted, high-energy solid components are added and mixed to form a slurry, and then injected into a mold or a projectile body, and cooled and solidified into a charge with a certain shape and size. It has the advantages of strong adaptability to ammunition, high charging efficiency, easy recycling and low manufacturing cost, and is the mainstream charging process for ammunition at present. At present, a large number of non-nuclear warheads adopt the cast charge technology, and it is expected to remain the main ammunition charging method for a long time in the future.

[0003] There are mainly two processes for the melting and casting of high-energy explosives: one is the casting of pure TNT, and the other is to add high-energy explosive solid particles (RDX, HMX) and aluminum powder into the molten TNT carrier and mix them before casting. Since the energy of pure TNT is relatively low, the mixed cast explosives are mainly used now. The processes of filling various ammunitions with cast explosives are similar, and its basic process can be divided into processes such as melting, mixing, casting, cooling, removing risers, cleaning, and inspection of the explosives. However, according to the technical conditions of various ammunitions and products, there are different specific charging processes.

[0004] With the development of modern weapon ammunitions towards high-efficiency damage, high battlefield survivability and high reliability, higher requirements are put forward for the explosive charging performance and charging process level in weapons. One of the ways to improve the high-efficiency damage of ammunitions is to synthesize a cast charge carrier explosive with higher energy, but it is difficult to meet the development requirements of current weapon ammunitions at the same time; another effective way is to increase the content of high-energy solid components in the cast charge. However, with the increase of the solid-phase mass fraction, the viscosity of the cast charge will increase significantly, which brings difficulties to the mixing process of the cast charge, reduces the mixing efficiency, and brings greater safety risks to the same mixing equipment.

[0005] The melting and mixing pot is used to mix various component materials into a uniform finished liquid medicine through stirring. The melting and mixing pot mainly consists of a butterfly-shaped pot cover, a cylindrical pot body, a hemispherical pot bottom, stirring blades, mounting lugs, an automatic feeding valve, etc. The hemispherical pot bottom is welded to the cylindrical pot body, and the inner wall is mirror-polished. The pot cover and the pot body are connected by a bolt flange, and there is a 5-mm-thick silicone rubber sealing ring between the pot cover and the pot body, which is pressed by quick-lock bolts to form a reliable seal. The mounting lugs are installed on the weighing module in the form of three lugs.

[0006] The pot body and the pot cover of the melting and mixing pot are both designed with double interlayers, and the whole is divided into three layers: the material layer, the jacket layer, and the insulation layer. The inner wall of the material layer is made of 316L stainless steel with a wall thickness of 6 mm. The jacket layer is a superheated water layer to achieve uniform heat preservation and heating of the whole melting and mixing pot, and the material is made of 304 stainless steel. The insulation layer uses rock wool for heat preservation to prevent scalding. The thickness of the insulation layer is 100 mm, and a 2-mm stainless steel outer cladding is used.

[0007] The pot cover is provided with a liquid-phase feed port, a solid-phase feed port, a gas-phase temperature detection port, a rain shower dust removal port, superheated water inlet and outlet ports, and a gas port, which are respectively used to connect to the liquid-phase feeding device, the solid-phase feeding device, the gas-phase temperature sensor, the rain shower and dust removal system, and superheated water, gas pipes, etc. The feeding pipeline and the feeding device are connected by a hose quick-loading connection method, which is convenient for disassembly and cleaning. At the same time, in order to facilitate manual observation and feeding, a manhole is also provided on the pot cover, and the manhole is equipped with a sealing cover that can be manually sealed.

[0008] The pot body is provided with a liquid-phase temperature detection port, a discharge port, and superheated water inlet and outlet ports, which are respectively used to connect to the liquid-phase temperature sensor, the automatic discharge valve, and the superheated water system. The liquid-phase temperature detection port is set at a suitable position on the lower head according to the detection needs, and the discharge port is set directly below.

[0009] Due to the traditional method that requires a single pot to complete the feeding and mixing of all materials, the single-shaft propelling impeller needs to complete the mixing in different process stages. Since the mixing process of cast melt explosives is to add different materials in stages and stir and mix them evenly. First, the carrier explosive is added to the melting and mixing pot, and in the second step, aluminum powder is added and stirred for a certain time. In the third step, after the aluminum powder is mixed evenly, AP is added and stirred. In the fourth step, after the AP is stirred and mixed evenly, high-energy explosive (RDX or HMX) is added and stirred and mixed evenly, and then the material is discharged for casting and nursing to form. The defects of this process and equipment are that since there is only a single-shaft impeller in this mixing process, it is impossible to take into account the viscosity change in the mixing process, and there is a situation where the rotational speed and the impeller structure do not match the viscosity. At the same time, in order to ensure a certain production efficiency, the melting and mixing pot cannot be too small. Currently, it is generally 600 liters in the industry. This leads to a large amount of on-line medicine in the whole production process. At the same time, due to the large size of the mixing pot and the large diameter of the stirring impeller, under the same rotational speed condition, its linear velocity increases, increasing the risk in the stirring process.

[0060] Further, the first metering component, the second metering component, and the third metering component all include load cells located below the corresponding melting and mixing pots.

[0061] To further reduce the labor intensity of workers and achieve automatic feeding and feeding into each hopper, the embodiments of the present application may further provide that feeding robots 7 are provided on the first platform 11, the second platform 12, and the third platform 13; the feeding robots 7 are connected to the controller; the controller is further configured to control the corresponding feeding robots 7 to add materials.

[0062] Furthermore, it further includes a raw material elevator 8 located on the side of the multi-layer mounting rack 1, and bucket transfer lines 9 are provided on the first platform 11, the second platform 12, and the third platform 13; the bucket transfer lines 9 are used to transfer the buckets provided by the raw material elevator 8, so that after the feeding robots 7 grab the buckets, materials can be added.

[0063] To further improve the safety during the heating process of the carrier explosive, the embodiments of the present application may provide that the carrier explosive melting pot 31 melts the carrier explosive through thermal radiation.

[0064] The system provided by the embodiments of the present application can be used to realize the mixed production and use of various different types of cast explosives. When specifically used, only the carrier explosive and the solid-phase high-energy materials adapted to different types of cast explosives need to be selected. For example, in one implementation manner, the embodiments of the present application may provide that the carrier explosive includes any one of TNT explosive and DNAN explosive. The first solid-phase high-energy material includes AP material, the second solid-phase high-energy material includes high-energy explosive, and the third solid-phase high-energy material includes any one of aluminum powder material, ammonium perchlorate material, and cyclotrimethylenetrinitramine material.

[0065] As Figure 2 shown, the use process of the system provided by the embodiments of the present application may include:

[0066] First, a transfer vehicle automatically transports the buckets of various materials to the AGV transfer and temporary storage area, the AGV transfers the buckets to the raw material elevator 8, and the raw material elevator 8 transfers the buckets to the bucket transfer lines 9 on the corresponding platforms according to the types of materials in the buckets. The feeding robots 7 on the corresponding platforms grab the buckets and transfer the internal materials to the corresponding material temporary storage hoppers to achieve automatic feeding.

[0067] Then start the mixing program. The carrier explosive melting pot 31 melts the A material (carrier explosive) to the set time, the lower valve opens, and the liquid medicine of the melted A material is put into the first melting and mixing pot 32. At the same time, the lower valve of the B material (AP material) opens, and the B material starts to be added to the first melting and mixing pot 32. The first melting and mixing pot 32 stirs synchronously. After the A and B materials are detected by the metering system, the feeding stops, and stirring continues for a certain time to prepare for discharging.

[0068] The valve below the first melting and mixing pot 32 is opened, and the slurry is put into the second melting and mixing pot 33. At the same time, material C (high-energy explosive) starts to be added, and the second melting and mixing pot 33 stirs synchronously. When the metering system of the first melting and mixing pot 32 detects that the slurry has been discharged completely, the valve is closed. At the same time, it is controlled that the feeding of material C is also completed. The second melting and mixing pot 33 continues to stir for a certain period of time and prepares for discharging; the valve of the first melting and mixing pot 32 is closed, signals are given to materials A and B above, and materials A and B continue to be added, and the first melting and mixing pot 32 continues to stir.

[0069] The valve below the second melting and mixing pot 33 is opened, and the slurry is put into the third melting and mixing pot 34. At the same time, material D (aluminum powder material) starts to be added, and the third melting and mixing pot 34 stirs synchronously. When the metering system of the second melting and mixing pot 33 detects that the slurry has been discharged completely, the valve is closed. At the same time, it is controlled that the feeding of material D is also completed. The third melting and mixing pot 34 continues to stir for a certain period of time and prepares for discharging; the valve of the second melting and mixing pot 33 is closed, signals are given to the first melting and mixing pot 32 and material C above, and the first melting and mixing pot 32 and material C continue to be added, and the second melting and mixing pot 33 continues to stir.

[0070] The third melting and mixing pot 34 stirs for a certain period of time, automatically discharges the material to the component detection device 4, automatically detects the components. If the detection is qualified, the material is discharged to the slurry receiving bucket 5. If the components do not meet the requirements, the third melting and mixing pot 34 continues to stir for a certain period of time and then conducts component detection again.

[0071] The above three melting and mixing pots stir different materials in sequence, realizing continuous feeding of materials and synchronous stirring, greatly optimizing the stirring time and improving the stirring efficiency.

[0072] In summary, the pulse distributed melting and casting charging mixing system provided by the present application uses three-layer special melting and mixing pots to replace the original mixing pot, and completes the mixing of carrier explosives with raw materials such as aluminum powder, ammonium perchlorate, and cyclotrimethylenetrinitramine in different pots respectively to form cast explosives. It solves the problems existing in the prior art that all raw materials are mixed in one pot, such as a large amount of online medicine, a large linear speed of mixing and stirring, and low mixing efficiency. By adopting the pulsating split mixing method, different materials are mixed in different melting and mixing pots to achieve safe and efficient mixing of cast explosives.

[0073] Meanwhile, the use of the feeding robot can reduce the operators on the casting production line, lower the labor intensity of the personnel, improve the production efficiency of the production line, use the barrel conveyor line for material lifting and conveying, and combine with the feeding robot to achieve automatic transfer of materials. Precise metering of the addition to the melting and mixing pot is carried out through the metering and receiving station to ensure the accuracy of the feeding into the melting and mixing pot, providing front-end support for uniform mixing of the materials. Precise metering of the material addition is carried out through the material storage hopper to prepare the materials for uniform mixing. The material melting pot safely and efficiently melts the carrier explosive (TNT or DNAN) through thermal radiation, preparing for the preparation of cast explosives and serving as a prerequisite for the mixing of cast explosives.
