Description

Technical Field

[0001] The invention relates to the technical field of emulsion explosives, in particular to an emulsion explosive density detection device. Background Art

[0002] Density testing of emulsion explosives involves the precise measurement of the mass per unit volume of emulsion explosives. It is a critical quality control and safety indicator in industrial production and use. Its core objective is to obtain the density of emulsion explosives through standardized methods to assess whether their performance meets standard requirements.

[0003] The density of emulsion explosives is typically tested using the volumetric method, also known as the weighing method. To ensure accurate test results, the volumetric method requires pre-coating a thin layer of oil (such as light mineral oil or silicone oil) on the inner wall of the container. This oil film forms a lubricating layer between the container wall and the emulsion explosive, reducing flow resistance. This allows the sample to flow smoothly, making it easier to fill the bottom and corners of the container and avoid dead-end cavities. Existing emulsion explosive density testing devices do not have this function, requiring personnel to manually apply a thin layer of oil to the inner wall of the container. Summary of the Invention

[0019] Working principle: First, the staff pours a thin layer of coating oil into the inner cavity of the discharge tank 14 through the feed pipe, and starts the small cylinder 21 to drive the lifting tube 16 to move upward. When the lifting tube 16 moves upward, it can drive the feed tank 15 to move upward synchronously. When the feed tank 15 moves upward, the top flip plate 30 can fit with the insertion rod 32, thereby driving the flip plate 30 to flip. When the flip plate 30 flips, the thin layer of coating oil in the inner cavity of the discharge tank 14 will enter the inner cavity of the feed tank 15. When the thin layer of coating oil enters the inner cavity of the feed tank 15, it can flow into the bottom of the inner cavity of the lifting tube 16. When the loading is completed, the small cylinder 21 can drive the lifting tube 16 to move downward, so that the through hole on the outside of the lifting tube 16 is aligned with the feed hole, so that the thin layer of coating oil enters the inner cavity of the discharge box 20. At the same time, the lifting tube 16 When it moves downward, it can drive the two swing plates 18 to swing in opposite directions. The swing plates 18 swing with the hinge rod 19 as the center of the circle. When the swing plate 18 swings, it can drive the annular cleaning cotton 17 to move upward and drive the baffle 33 to move upward. When the baffle 33 moves upward, a thin layer of oil flows downward through the annular mouth and enters the interior of the annular cleaning cotton 17 to complete the mixing. When the cleaning motor 11 is started, it can drive the annular cleaning cotton 17 to rotate. When the two screw rods 6 are started, they can drive the two movable blocks 13 to move upward. When the movable block 13 moves upward, it can drive the container 4 to move upward through the sleeve plate 7, so that the annular cleaning cotton 17 is smeared on the inner wall of the container 4, reducing the friction resistance of the wall, making the sample flow smoothly, and significantly reducing the chance of tiny bubbles adhering to the wall.
