Description

TECHNICAL FIELD

[0001] The utility model relates to the field of powder industrial explosive detonation velocity test technology, especially to a kind of filling device of powder explosive natural accumulation. BACKGROUND

[0002] At present, in the field of metal explosion welding, powder explosives are naturally laid flat on the surface of the metal to be welded, and different metal materials are welded together by high temperature and high pressure generated by explosive explosion. This method has strict requirements on the natural accumulation detonation velocity of explosives. Therefore, the detonation velocity of explosives under natural accumulation needs to be tested before explosion welding. At present, each manufacturer has its own testing method, and there is no unified testing standard. In particular, there is no unified standard for the natural accumulation filling method of explosives. Most of the time, explosives are poured into the test box by hand, which causes uneven density of explosives, and the density is large or small.

[0003] The Chinese utility model with application number 202021119824.8 discloses a powder explosive detonation velocity test box for explosion welding, which includes a test box, a detonator mounting hole, a detonation velocity probe mounting hole, a detonation velocity probe, a support rod, a sliding rail, a feeding barrel, a feeding pipe, a plate chain and a plate chain rack. The utility model does not solve the defects of the prior art. UTILITY MODEL CONTENT

[0004] The present application solves the problem that most users do not have a unified standard for the natural accumulation filling method of explosives in detonation velocity testing, and explosives are poured into the test box by hand, which causes uneven density of explosives and affects the scientificity and rigor of the test results.

[0005] Therefore, the present application provides a filling device for powder explosive natural accumulation, which includes a cuboid box body, and a funnel device is arranged in the cuboid box body. The funnel device is characterized by the following features: the funnel device has a trapezoidal structure with a larger upper inlet than lower outlet; a screen is arranged in the funnel device; and a guide portion is further arranged at the lower part of the funnel device, which extends to the detonation velocity test device and allows the powder explosive to naturally accumulate in the detonation velocity test device.

[0006] The effect is that the hollow trapezoidal structure of the funnel device allows the powder explosive to fall down from top to bottom in a concentrated and uniform manner, so that it can accurately fall into the lower container. The screen can control the uniformity of the natural falling of the powder explosive, and prevent the powder explosive from being excessively accumulated to ensure the consistency of the explosive density, thereby further adjusting the accuracy of the detonation velocity test results. The guide portion effectively prevents the powder explosive from scattering outside the box containing the explosive, and further improves the overall performance of the utility model.

[0007] Further improvement lies in that the length of the upper inlet of the trapezoidal structure of the funnel device is 300±10mm, and the width is 100±10mm; the length of the lower outlet of the trapezoidal structure is 270±10mm, and the width is 60±10mm.

[0008] Effects lie in that the values of the funnel device are favorable for the uniformity of the diameter density of the powdery explosive after filling.

[0009] Further improvement lies in that the cuboid box body has the following dimensions: the length is 300±10mm, the width is 100±10mm, and the height is 60±10mm.

[0010] Effects lie in that the values of the cuboid box body are favorable for the uniformity of the diameter density of the powdery explosive after filling.

[0011] Further improvement lies in that the guiding part is through from top to bottom, and the inner dimension of the guiding part is equal to the size of the lower outlet of the trapezoidal structure of the funnel device.

[0012] Effects lie in that the guiding part is through from top to bottom, and the inner dimension of the guiding part is equal to the size of the lower outlet of the trapezoidal structure of the funnel device, so that the guiding part and the funnel device are seamlessly connected and can guide the natural falling of the powdery explosive.

[0013] Further improvement lies in that the length of the inner wall of the cuboid of the guiding part is 300±10mm, the width is 60±10mm, and the height is 40±10mm.

[0014] Effects lie in that the guiding part is through from top to bottom, and the inner dimension of the guiding part is equal to the size of the lower outlet of the trapezoidal structure of the funnel device, so that the guiding part and the funnel device are seamlessly connected and can guide the natural falling of the powdery explosive.

[0015] Further improvement lies in that the mesh number of the screen is 8-10.

[0016] Effects lie in that the screen with the mesh number of 8-10 can effectively control the uniformity of the natural falling of the powdery explosive and the consistency of the density of the fallen explosive.

[0017] Beneficial effects:

[0018] The filling device for the natural accumulation of the powdery explosive can effectively solve the problem that the explosive cannot be naturally accumulated on the filling method in the detonation velocity test, and the problem that the explosive density is uneven due to the fact that the explosive is generally scattered into the test box by hand, thereby affecting the scientificity and rigor of the test results. In addition, the device is simple, low in cost, convenient to use, high in practicability, uniform in filling density, and the like. Furthermore, the device can be used as a standard for the production of the unified detonation velocity test. BRIEF DESCRIPTION OF DRAWINGS
