Description

Technical Field

[0001] The utility model relates to the technical field of explosive production equipment, in particular to a bag-kicking device for packing a finished product of expanded ammonium nitrate explosive. Background Art

[0002] Expanded ammonium nitrate explosive is a commonly used industrial explosive. It is a powdered mixed explosive composed of expanded (microporous and flaky) ammonium nitrate as the main oxidant, an appropriate amount of combustible agent and other functional additives. Its microporous structure has a sensitizing effect that can form hot spots for detonation, without the need to add single explosives, highly sensitive salts or metal powders as sensitizers in general industrial explosives, which can reduce costs, pollution and dangers in production and use.

[0003] In addition, during the packaging process of this type of powdered explosives, since the powder contains a large amount of gas, the powder is very fluffy when filled into the packaging bag, and the space of the packaging bag cannot be fully utilized, resulting in a low utilization rate of the packaging bag, reducing the efficiency of bagging, causing waste of packaging bags, and is not conducive to the stability and safety of explosive storage. For this reason, we designed a densification and bag-kicking device for the finished packaging of expanded ammonium nitrate explosives to solve the above technical problems. Utility Model Content

The telescopic column 18 is fixedly provided at the bottom of the annular plate 15, and a connecting plate is provided at the other end of the telescopic column 18.

[0024] The end of the conveyor belt 3 is located just above the top opening of the bagging barrel 12.

The figure also simply shows that through the design of the device, the explosive material 2 conveyed on the conveyor belt 3 can be smoothly dropped into the packaging bag placed inside the bagging barrel 12.

[0025] Specifically, when in use, the packaging bag is simply put on the top opening of the bagging barrel 12, similar to the common practice of putting a garbage bag into a garbage can, and then the first electric push rod 13 is started. The first electric push rod 13 drives the annular plate 15 to move downward through the connecting block 14 until each extrusion wheel 20 abuts against the packaging bag and the extrusion wheel 20 is embedded in the corresponding track groove 17. At this time, the telescopic column 18 is shortened, and the spring 19 is compressed to generate elastic force, that is, the extrusion wheel 20 has an extrusion force on the packaging bag, which can fix the position of the packaging bag. As the explosive material 2 is filled and loaded, the first electric push rod 13 is slightly extended, and the elastic force of the spring 19 is weakened. The packaging bag can move downward under the gravity of the explosive material 2. This process drives the extrusion wheel 20 to rotate until the bottom of the packaging bag abuts against the bottom wall of the bagging barrel 12, and the filling is continued until it is initially full; then the built-in motor is started, and the built-in motor drives the rotating plate 21 to rotate, thereby driving the limit column 26 to rotate The moving rod 23 can move back and forth under the limiting action of the limiting sleeve 25, so the buffer block 24 can be used to continuously impact the outer wall of the bagging barrel 12, thereby continuously vibrating the front and rear sides of the packaging bag at the same time, thereby increasing the density of the explosive material 2 inside the packaging bag; next, the driving motor 11 is started, and the driving motor 11 drives the second gear 5 to rotate, thereby driving the first gear 6 to rotate, that is, driving the circular plate 7 to rotate, thereby driving the bagging barrel 12 together with the packaging bag containing the explosive material 2 to rotate to the bottom of the extrusion plate 8, and then starting the second electric push rod 10, the second electric push rod 10 drives the extrusion plate 8 to move downward into the bagging barrel 12, and compacts the explosive material 2, further increasing the density of the explosive material 2 inside the packaging bag, making full use of the packaging bag space, and improving the utilization rate of the packaging bag. At the same time, the compacted explosive material 2 also has higher stability and safety.

[0026] It should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
