TECHNICAL FIELD

[0001] The utility model relates to a kind of energetic crystal particle size grading devices, belong to energetic crystal material processing technical field. BACKGROUND

[0002] Energetic crystal material is the core component of charge, to improve the density of charge, need to select different particle size crystal for grading, and the narrower the particle size distribution of each particle size crystal is more conducive to digital grading.

[0003] After the preparation of energetic crystal material, the energetic crystal material in the reaction kettle coexists in various particle sizes. To collect energetic crystal material of a specific particle size and improve the narrow distribution index of particle size in energetic crystal material, the common method is sieving, which relies on sieve holes to obtain crystals of a specific particle size. For different particle size requirements, multiple sieving is required, which is labor-intensive and low in work efficiency. Moreover, sieving is suitable for large particle size crystals, but not for batch manufacturing of small particle size crystals in micrometer or quasi-micrometer level. SUMMARY

[0004] The utility model discloses a kind of energetic crystal particle size grading devices to solve the shortcomings of traditional sieving method, such as large labor intensity, low work efficiency, and not suitable for batch manufacturing of small particle size crystals in micrometer or quasi-micrometer level.

[0006] The utility model discloses a kind of energetic crystal particle size grading devices, including cuboid structure's grading box, be set in the left side of the liquid inlet of the grading box top, be set in the right side of the liquid outlet of the grading box top, vertically fixed in the group of the same height baffle of the grading box bottom plate upper surface, the group of collection funnel of aperture connection in the grading box bottom plate below, be set in the discharge port of each collection funnel bottom;

[0007] The baffle separates the bottom of the grading box into crystal collection areas spaced from each other, and each collection funnel is arranged below each crystal collection area.

[0008] By controlling the circulation of the material liquid containing energetic crystals from the liquid inlet to the liquid outlet, the energetic crystals in the material liquid fall into different collection funnels by gravity.

[0009] The collection funnel is a downward converging cone structure.

[0010] Working process

[0011] After the liquid containing energetic crystals enters the classifying tank through the inlet, it flows towards the outlet at a certain flow rate. As the energetic crystals move horizontally with the liquid, they also slide downwards in a parabolic trajectory under the influence of gravity. Because the energetic crystals in the liquid have different particle sizes, they fall into different collecting funnels according to their size. The energetic crystals of various particle sizes are then collected through the outlets at the bottom of each collecting funnel, thus achieving particle size separation of the energetic crystals in the liquid.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example

[0020] like Figures 1-3 As shown, the present invention provides a particle size classification device for energetic crystals, comprising a rectangular parallelepiped classification box 6, an inlet 1 located on the upper left side of the classification box 6, an outlet 2 located on the upper right side of the classification box 6, a set of partitions 3 of the same height vertically fixed to the bottom plate of the classification box 6, a set of collecting funnels 4 with openings connected to the bottom plate of the classification box 6, and a discharge port 5 located at the bottom of each collecting funnel 4.

[0021] The partition 3 divides the bottom of the grading box 6 into mutually spaced crystal collection areas, and each collection funnel 4 is respectively set below each crystal collection area.

[0022] By controlling the circulation of the liquid containing energetic crystals from the inlet 1 to the outlet 2, the energetic crystals in the liquid fall into different collection funnels 4 by their own weight.

[0023] The collecting funnel 4 is a downward converging cone structure.

[0024] After the feed liquid containing energetic crystals enters the grading box 6 from the liquid inlet 1, it flows in a certain flow rate to the liquid outlet 2 direction, and the energetic crystals in the feed liquid move horizontally while falling downward in a parabolic shape under the action of gravity. Because the particle sizes of the energetic crystals in the feed liquid are different, the energetic crystals will fall into different collecting funnels 4 according to the size of the particle size, and then the energetic crystals of various particle size ranges are collected through the discharge outlets 5 at the bottoms of the collecting funnels 4, so as to realize the particle size screening of the energetic crystals in the feed liquid.
