Description

Technical Field

[0001] The invention relates to the technical field of energetic material parameter detection, and in particular to a molten cast energetic material viscosity detection device with heating and heat preservation functions. Background Art

[0002] The preparation of molten energetic materials refers to a method of directly casting products after melting energetic materials at high temperatures. This method usually involves melting in an electric arc furnace, then pouring into a high temperature resistant mold, and then cooling, crystallizing, annealing or cutting to form products. During the production process, the melting atmosphere, melting temperature and cooling conditions are controlled to ensure high production efficiency, crystallization that meets requirements and the formation of a network structure. Molten energetic materials are widely used in military and civilian fields.

[0003] The parameter detection of molten-cast energetic materials is used to obtain the physical parameters required for calculation by the molten-cast filling process simulation software. At present, the viscosity detection of mixed explosives mostly adopts the traditional method of visual observation and counting to calculate the time required for the flow of a fixed volume of material, so as to convert the viscosity. In specific implementation, after a period of insulation, the plug is manually opened and the material begins to flow out. When the material liquid level passes through indicator needle 1, the timing starts, and when the liquid level passes through indicator needle 2, the timing stops. Then, the viscosity of the material is converted according to the fixed formula based on the recorded time.

[0004] However, the manual observation method has large errors and high risk factors, which has a great impact on the subsequent simulation software calculations. At the same time, the product is an energetic material, and manual observation and timing are highly dangerous. Summary of the invention

[0045] A heat preservation unit 2, wherein the heat preservation unit 2 is connected to the support 1, and the heat preservation unit 2 is used to heat the explosive inside the heat preservation unit 2 so as to transform the explosive from a solid state into a liquid fluid;

[0046] A discharge unit 3, the discharge unit 3 is connected to the heat preservation unit 2, and the discharge unit 3 is used to open and close the discharge port of the heat preservation unit 2;

[0047] The weighing unit 4 comprises a weighing module 41 and a material receiving barrel 42. The material receiving barrel 42 is located at the upper part of the weighing module 41. The material receiving barrel 42 is used to receive the liquid explosive flowing out through the discharge port so that the weighing module 41 can weigh the liquid explosive. In specific implementation, the weighing module 41 comprises any one of a gain-in-weight weighing module and a loss-in-weight weighing module.

[0048] A controller, the controller is connected to the heat preservation unit 2, the discharge unit 3 and the weighing unit 4;

[0049] The controller is used to perform the following operations:

[0050] Controlling the discharge unit 3 to block the discharge port;

[0051] Controlling the heat preservation unit 2 to heat the solid explosive inside the heat preservation unit 2;

[0052] After determining that the explosive is transformed from a solid state to a liquid fluid, the discharge unit 3 is controlled to open the discharge port, so that the explosive in a liquid fluid state flows into the receiving barrel 42 through the discharge port;

[0053] After the material discharge is completed, the material discharge time of the material discharge process is recorded, and the weight change value collected by the weighing module 41 is received;

[0054] The viscosity value of the explosive is calculated using the discharge time and the weight change value.

[0055] The viscosity detection device for molten cast energetic materials provided in the embodiment of the present application can realize the automatic execution of steps such as explosive heating, discharging, and weighing through a controller. During the viscosity detection process, personnel do not need to be close to the equipment, which greatly improves the safety of the detection process. The mixed explosive can be heated and insulated by the insulation unit 2 to turn the solid explosive into a liquid fluid. The discharge unit 3 can realize automatic discharge, facilitate remote operation, and reduce the risk of manual operation. The weighing unit 4 can automatically complete the weighing, calculate the time and flow rate of the material outflow by weighing the outflowing material, and indirectly measure the viscosity of the material. The operation is simple and the accuracy is high.

[0056] The heat preservation unit 2 provided in the embodiment of the present application is used to heat the solid explosive so that the explosive is transformed from a solid state to a liquid fluid, which facilitates the flow of the explosive. In order to improve the safety during heating, the embodiment of the present application can provide that the heat preservation unit 2 includes a cone 21, a heat preservation cavity 22 located outside the cone 21, and a heating medium supply mechanism, wherein the interior of the cone 21 is used to accommodate the explosive; and the controller is connected to the heating medium supply mechanism.

[0057] Further, such as Figure 2 , Figure 3 As shown, the heating medium supply mechanism includes a feed pipe 23 connected to the upper part of the heat preservation cavity 22 and a discharge pipe 24 connected to the lower part of the heat preservation cavity 22. The heating medium can be a liquid fluid or a gaseous fluid, which is added into the heat preservation cavity 22 through the feed pipe 23, and the heating medium can be discharged through the discharge pipe 24 after heat exchange. Since there is no open flame during the heating process, the safety of the heating process can be greatly improved.

[0058] In order to facilitate the addition of explosives into the cone 21 and the outflow of liquid explosives, the embodiment of the present application may provide that a cover plate 25 is provided on the upper part of the cone 21, and the discharge port is provided at the bottom of the cone 21.

[0059] The discharge unit 3 provided in the embodiment of the present application is mainly used to control whether the explosive in the cone 21 flows out. The discharge unit 3 can be in various forms. For example, in one implementation, Figure 4 As shown, the embodiment of the present application can provide that the discharge unit 3 includes a clamping cylinder 31, a blocking plate 32 and a connecting plate 33; the cylinder body of the clamping cylinder 31 is connected to the insulation unit 2, and the blocking plate 32 is connected to the piston rod of the clamping cylinder 31 through the connecting plate 33; the controller is connected to the clamping cylinder 31.

[0060] In this mode, when the detection device is implemented, the cone 21 and the insulation cavity 22 are seamlessly fitted, the material is placed in the cone 21, and the heating medium is placed in the insulation cavity 22 to heat the material in the cone 21. The clamping cylinder 31 of the discharge unit 3 is retracted, so that the blocking plate 32 blocks the outflow of the insulation unit 2, the material is placed in the cone 21, and the heating medium is introduced to heat the material. After the material is heated, it becomes fluid, so that the clamping cylinder 31 extends, and the material flows out of the insulation unit 2 and falls into the receiving barrel 42 below, and the weighing module 41 starts to record the weight change. When the material flows out completely, the viscosity of the material is calculated by taking the time period when the weight changes evenly.

[0061] In another implementation, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the embodiment of the present application can also provide that the discharge unit 3 includes a linear cylinder 34, a blocking inclined block 35, a discharge flange 36 and a flange baffle 37; the discharge flange 36 is connected to the discharge port, the discharge flange 36 is connected to the flange baffle 37, and the flange baffle 37 is provided with a slide groove for the blocking inclined block 35 to slide; the piston rod of the linear cylinder 34 is connected to the blocking inclined block 35;

[0062] The discharge flange 36 is provided with a through hole running through from top to bottom and a side opening for the blocking bevel block 35 to enter and exit, and a slope structure is formed at the position where the side opening is connected to the through hole; the linear cylinder 34 is used to drive the blocking bevel block 35 to slide along the slide groove so as to enter and exit the discharge flange 36 through the side opening, so that after the blocking bevel block 35 enters the interior of the discharge flange 36, the blocking slope of the blocking bevel block 35 contacts the slope structure to achieve blocking of the through hole.

[0063] Furthermore, the angle of the blocking slope of the blocking slope block 35 is 0° to 90°.

[0064] In the specific implementation of the detection device in this mode, the cone 21 and the heat preservation cavity 22 are seamlessly fitted, the material is placed in the cone 21, and the heating medium is placed in the heat preservation cavity 22 to heat the material in the cone 21. The linear cylinder 34 extends to make the blocking inclined block 35 block the outflow of the discharge flange 36, put the material into the cone 21, and pass the heating medium to heat the material. After the material is heated, it becomes fluid, so that the linear cylinder 34 retracts, and the material flows out of the heat preservation unit 2 and falls into the receiving bucket 42 below, and the weighing module 41 starts to record the weight change. When the material flows out completely, the viscosity of the material is calculated by taking the time period when the weight changes evenly.

[0065] In summary, the viscosity detection device for molten-cast energetic materials provided by the present application can heat the mixed solid explosive to make it fluid through the heat preservation unit, and flow out under the control of the discharge unit, and record its weight change process through the high-precision weighing module, thereby indirectly detecting the viscosity of the mixed explosive, with a simple structure and convenient operation. The entire detection process can be completed automatically, which is convenient for remote operation, reduces the risk of manual operation, can effectively improve the accuracy of viscosity detection, and has good safety.
