Description

Technical Field

[0001] This utility model relates to the field of emulsion explosives technology, and in particular to an emulsion stirring device for emulsion explosives. Background Technology

[0002] Emulsion explosives are water-in-oil emulsion explosives formed by uniformly dispersing microdroplets of oxidizing salt aqueous solutions in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres, with the help of emulsifiers. During the preparation of emulsion explosives, the raw materials need to be thoroughly stirred. However, during the stirring process, the raw materials can only be stirred in one direction. The stirring direction of the stirring device is relatively singular, resulting in low stirring efficiency and excessively long stirring time. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide an emulsification and stirring device for emulsified explosives, which makes the emulsified explosives more dispersed and uniform, improves stirring efficiency, and shortens stirring time.

[0004] The emulsified explosive emulsification and stirring device proposed according to this utility model includes a support plate, bearings fixed at the top and bottom of the support plate, a stirring cylinder internally interference-connected to the two bearings, a toothed ring fixed on the outer surface of the stirring cylinder, a first motor fixed at the top of the support plate, and a gear meshing with the toothed ring fixed at the rotating end of the first motor.

[0005] Preferably, cylinders are fixed at both the left and right ends of the top of the support plate, and cover plates are fixed at the telescopic ends of the two cylinders.

[0006] Preferably, a second motor is fixed at the top center of the cover plate, and the rotating end of the second motor passes through the cover plate and is fixed with a stirring rod located inside the stirring drum.

[0007] Preferably, support rods are provided at both ends of the support plate, a third motor is fixed to one side of the support rod, and the third motor is connected to the support plate through a rotating shaft.

[0008] Preferably, the bottom of the two support rods is fixed with a base for supporting the overall structure.

[0009] Preferably, a first baffle is fixed to the left and right inner walls of the mixing drum, and a second baffle is fixed to the bottom inner wall of the mixing drum. The first and second baffles are used to stir the emulsion explosive inside the mixing drum and to turbulent the emulsion explosive inside the mixing drum.

[0010] Preferably, the rotation directions of the first motor and the second motor are opposite, which can generate stronger shear force and turbulence, which helps to break up the agglomeration in the emulsion explosive.

[0011] The beneficial effects of this invention are as follows: the second motor drives the stirring rod to fully stir the emulsion explosive inside the stirring drum, while the first motor is started. The rotating end of the first motor drives the gear and the meshing gear ring to rotate, and the rotation of the gear ring causes the stirring drum to rotate around the center of the bearing. While the stirring drum is rotating, the emulsion explosive inside is stirred by the first and second baffles. At the same time, because the rotation direction of the stirring drum is opposite to the rotation direction of the stirring rod, the emulsion explosive is more dispersed and uniform, which also improves the stirring efficiency and shortens the stirring time.

[0018] Reference Figure 1-5An emulsifying and stirring device for emulsified explosives includes a support plate 1. Bearings 2 are interference-fitted to the top and bottom of the support plate 1. A stirring cylinder 3 is interference-fitted inside the two bearings 2. A gear ring 4 is interference-fitted to the outer surface of the stirring cylinder 3. A first motor 5 is threaded to the top of the support plate 1. A gear 6 meshing with the gear ring 4 is fixed to the rotating end of the first motor 5. When the first motor 5 is started, the rotating end of the first motor 5 drives the gear 6 to rotate, and the rotation of the gear 6 drives the meshing gear ring 4 to rotate. The stirring cylinder 3 can rotate inside the bearing 2, while its outer side is fixed to the support plate 1. The bearing 2 supports the stirring cylinder 3, causing the rotation of the gear ring 4 to drive the stirring cylinder 3 to rotate around the center of the bearing 2.

[0019] The top left and right ends of the support plate 1 are threaded with cylinders 7, and the telescopic ends of the two cylinders 7 are threaded with cover plates 8. By starting the cylinders 7, the cylinders 7 drive the cover plates 8 to move upward, so that the cover plates 8 are away from the top of the mixing drum 3, which makes it convenient to add materials to the inside of the mixing drum 3, and also makes it convenient to pour out the emulsion explosive after mixing.

[0020] The top center of the cover plate 8 is threaded with a second motor 9. The rotating end of the second motor 9 passes through the cover plate 8 and is fixed with a stirring rod 10 located inside the stirring drum 3. By starting the second motor 9, the second motor 9 drives the stirring rod 10 to fully stir the emulsion explosive inside the stirring drum 3.

[0021] Support rods 11 are provided at both ends of the support plate 1. A third motor 12 is fixed on one side of the support rod 11. The third motor 12 is connected to the support plate 1 through a rotating shaft. When the third motor 12 is started, the rotating end of the third motor 12 drives the support plate 1 to rotate. The rotation of the support plate 1 drives the stirring drum 3 to flip, thereby pouring out the emulsion explosive inside the stirring drum 3.

[0022] The bottom of the two support rods 11 is fixed with a base 14 for supporting the overall structure.

[0023] The mixing drum 3 is equipped with first baffles 13 on both the left and right inner walls and a second baffle 15 on the bottom inner wall. As the mixing drum 3 rotates, the emulsion explosive inside is stirred by the first baffles 13 and the second baffles 15, and the emulsion explosive inside the mixing drum 3 is turbulent, so that the emulsion explosive inside the mixing drum 3 is stirred more thoroughly and quickly, which greatly speeds up the stirring efficiency.

[0024] The first motor 5 and the second motor 9 rotate in opposite directions, so that the rotation direction of the stirring drum 3 is opposite to that of the stirring rod 10. When the stirring drum 3 and the stirring rod 10 rotate in opposite directions, stronger shearing force and turbulence can be generated. This helps to break the agglomeration in the emulsion explosive, making the emulsion explosive more dispersed and uniform, and also improving the stirring efficiency and shortening the stirring time.

[0025] In use, the cylinder 7 is activated to move the cover plate 8 away from the mixing drum 3. The emulsion explosive to be stirred is then poured into the mixing drum 3. The cylinder 7 is then used to return the cover plate 8 to its initial position. Simultaneously, the second motor 9 is activated, driving the stirring rod 10 to thoroughly stir the emulsion explosive inside the mixing drum 3. At the same time, the first motor 5 is activated, its rotating end driving the gear 6 to rotate. The rotation of the gear 6 drives the meshing gear ring 4 to rotate, which in turn causes the mixing drum 3 to rotate around the center of the bearing 2. As the mixing drum 3 rotates... The emulsion explosive inside is stirred by the first baffle 13 and the second baffle 15, which also turbulents the emulsion explosive inside the stirring drum 3. Moreover, the rotation direction of the stirring drum 3 is opposite to the rotation direction of the stirring rod 10, which makes the emulsion explosive more dispersed and uniform, and also improves the stirring efficiency and shortens the stirring time. When the stirring is completed, the cover plate 8 is moved away from the stirring drum 3 by starting the cylinder 7. Then, the third motor 12 is started. The rotating end of the third motor 12 drives the support plate 1 to rotate, and the rotation of the support plate 1 causes the stirring drum 3 to flip, thereby pouring out the emulsion explosive inside the stirring drum 3.
