Description

Technical Field

[0001] This utility model relates to the field of packaging tube technology, specifically to packaging tubes for emulsion explosives. Background Technology

[0002] Emulsion explosives are water-in-oil emulsion explosives formed by using emulsifiers to uniformly disperse droplets of oxidizing salt aqueous solutions in a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres. In the production of emulsion explosives, the explosives need to be fed into a packaging tube, and then the packaging tube is sealed to package the explosives.

[0003] Patent publication number CN221376462U disclosed on July 19, 2024, an emulsion explosive packaging tube, comprising: a tube body, a connecting block, and a magnet block. A plug is connected through the top of the tube body, and a connecting cover is connected to the bottom of the tube body. One side of the connecting block is fixedly connected to the connecting cover, and a sealing block is fixedly connected to the other side of the connecting block. A spring is fixedly connected inside the connecting block, and a locking block is fixedly connected to one end of the spring. One side of the locking block is connected through the tube body. A connecting plate is connected through the inside of the connecting cover. A protrusion is welded and fixed to one side of the connecting plate. A lever is connected to one side of the protrusion, and a spring is connected to one side of the lever. An actuation groove matching the lever is opened inside the locking block. The connecting block and sealing block on one side of the connecting cover are aligned with the bottom of the cylinder. When the rubber sealing block contacts the cylinder, it deforms to adapt to the shape of the cylinder and seals the connection between the cylinder and the sealing block. When the inclined surface of the locking block on one side of the connecting block contacts the cylinder, the locking block moves. When the locking block moves, it compresses the spring on one side, causing it to contract. When the locking block contacts the locking groove inside the cylinder, the spring resets, pushing the locking block to engage with the cylinder, thus sealing the cylinder. This operation facilitates the sealing of emulsion explosive packaging cylinders. However, there are still shortcomings in practical applications: the position of the sealing block depends on the insertion and matching of the locking block with the cylinder's slot. This requires the corresponding slot structure to be machined on the inner wall of the cylinder during the manufacturing stage. If some explosive splashes and remains in the slot during the injection of emulsion explosive, it will directly hinder the normal insertion of the locking block, thereby affecting the fixing effect of the sealing block and reducing the reliability of the seal. Utility Model Content

[0004] The purpose of this invention is to provide an emulsion explosive packaging tube to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an emulsion explosive packaging cylinder, comprising a cylinder body, a connecting sleeve and a magnetic block fixedly connected to the middle side wall of the cylinder body, a hole opened at the upper end of the cylinder body and a hole plug inserted into the hole, a sealing block inserted into the lower end of the cylinder body, and a fixing cap fixedly connected to the lower end of the sealing block.

[0006] Two fixing strips are fixedly connected to the lower outer wall of the cylinder. A first magnetic strip is embedded in the upper end of each fixing strip. Two rotating plates are rotatably connected to the upper end of the fixing cover via a rotating shaft. Both rotating plates have an arc-shaped structure and their inner sides are tightly attached to the outer wall of the cylinder. The lower ends of the two rotating plates abut against the upper ends of the corresponding fixing strips.

[0007] Preferably, a second magnetic strip is embedded at the lower end of the rotating plate, and the second magnetic strip is magnetically connected to the corresponding first magnetic strip.

[0008] Preferably, a support rod is fixedly connected to the upper end of the rotating plate, and the support rod and the rotating shaft are located at the corresponding ends of the rotating plate.

[0009] Preferably, the connecting sleeve is made of a magnetically conductive material, and the connecting sleeve and the corresponding magnet block are arranged opposite to each other, with the inner size of the connecting sleeve matching the end size of the corresponding magnet block.

[0010] Preferably, the two fixing strips are the same size and can form a ring structure, and the outer diameter of the ring structure formed by the two fixing strips is the same as the diameter of the fixing cover.

[0011] Preferably, the sealing block is a circular structure made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: a fixing strip is set on the outer wall of the cylinder, and a rotating plate is hinged to the fixing cover by a rotating shaft. When sealing the cylinder, the rotating plate is rotated to abut against the upper end of the fixing strip, thereby locking the position of the fixing cover and thus firmly limiting the sealing block in the cylinder. This structure is set on the outside of the cylinder, which can effectively avoid the pollution problem caused by the splashing of explosives during the filling of emulsion explosives and ensure the installation reliability of the sealing block.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 The present invention provides the following technical solution:

[0020] Example 1: An emulsion explosive packaging tube includes a tube body 1. A connecting sleeve 2 and a magnetic block 3 are fixedly connected to the middle side wall of the tube body 1. The connecting sleeve 2 is made of magnetic material. The connecting sleeve 2 and the corresponding magnetic block 3 are arranged opposite to each other. The inner size of the connecting sleeve 2 matches the end size of the corresponding magnetic block 3. A hole is opened at the upper end of the tube body 1 and a hole plug 4 is inserted into the hole. A sealing block 7 is inserted into the lower end of the tube body 1. The sealing block 7 is a circular structure made of rubber. A fixing cap 8 is fixedly connected to the lower end of the sealing block 7.

[0021] Emulsion explosive is poured into cylinder 1. After pouring, sealing block 7 is snapped into the inside of cylinder 1 until fixing cover 8 abuts against cylinder 1. When the rubber sealing block 7 comes into contact with cylinder 1, it will deform to adapt to the shape of cylinder 1 and seal the connection of cylinder 1, sealing cylinder 1. The fuse can be inserted into cylinder 1 by opening the hole plug 4 at the top of cylinder 1, completing the production of emulsion explosive. When placing multiple devices, the magnet blocks 3 of two adjacent devices can be snapped into connecting sleeve 2. When the magnet blocks 3 come into contact with the magnetic connecting sleeve 2, the connecting sleeve 2 will attract the magnet blocks 3, completing the connection of the two devices. By connecting multiple devices, shaking and tipping during transportation can be prevented, improving the safety of transportation. The above operation makes it easy to combine and transport the devices.

[0022] Example 2: The technical solution of this example, which differs from that of Example 1, includes: two fixing strips 5 are fixedly connected to the lower outer wall of the cylinder 1. The two fixing strips 5 are the same size and can form an annular structure. The outer diameter of the annular structure formed by the two fixing strips 5 is the same as the diameter of the fixing cover 8. The upper end of each of the two fixing strips 5 is inlaid with a first magnetic strip 6. The upper end of the fixing cover 8 is rotatably connected to two rotating plates 10 through a rotating shaft 9. The two rotating plates 10 are both arc-shaped and their inner sides are tightly attached to the outer wall of the cylinder 1. The lower ends of the two rotating plates 10 abut against the upper ends of the corresponding fixing strips 5. The lower end of the rotating plate 10 is inlaid with a second magnetic strip 11. The second magnetic strip 11 and the corresponding first magnetic strip 6 are magnetically connected. The upper end of the rotating plate 10 is fixedly connected with a support rod 12. The support rod 12 and the rotating shaft 9 are respectively located at the two ends of the corresponding rotating plate 10.

[0023] In use, the emulsion explosive is first poured into the cylinder 1 as described in Example 1. Since the fixing strip 5 is located on the outside of the cylinder 1 and the rotating plate 10 is positioned on the fixing cover 8, the emulsion explosive will not splash onto the fixing strip 5 and the rotating plate 10 during the pouring process, thus preventing them from interfering with each other and affecting subsequent sealing. The sealing block 7 is then snapped into the lower end of the cylinder 1 to complete the initial seal. After the fixing cover 8 is attached to the lower end of the cylinder 1, the support rod 12 at the upper end of the rotating plate 10 is moved, causing the rotating plate 10 to rotate via the rotating shaft 9. The inner side of the rotating plate 10 is pressed tightly against the outer wall of the cylinder 1, and the lower end abuts against the upper end of the corresponding fixing strip 5. At this time, the second magnetic strip 11 at the lower end of the rotating plate 10 is magnetically connected to the first magnetic strip 6 at the upper end of the fixing strip 5, ensuring that the rotating plate 10 will not rotate arbitrarily. The rotating plate 10 pulls the fixing cover 8 through the rotating shaft 9, locking the position of the fixing cover 8 and firmly limiting the sealing block 7 inside the cylinder 1 to ensure reliable sealing. Later, when opening the cylinder 1, the rotating plate 10 can be rotated in the opposite direction, and the operator can hold the rotating plate 10 and pull the fixing cover 8 to pull the sealing block 7 out of the cylinder 1.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
