[0026] EMBODIMENT

[0027] Please refer to Figures 1-6The utility model provides a sealing storage calcium carbide packing barrel, including the barrel body 1, with the barrel bottom 3 of the lower surface sealed connection of barrel body 1, with the barrel top 2 of the upper surface sealed connection of barrel body 1, set up in the inflation mechanism 5 for the protection of the calcium carbide of filling nitrogen gas in the barrel body 1 in the barrel top 2, set up in the exhaust mechanism 6 for the automatic pressure reduction of the pressure of the barrel body 1 in the barrel top 2, the barrel mouth of the concentric setting in the middle position of barrel top 2 and the protruding surface of barrel top 2, and with the detachable connection of petal type barrel cover 4 of barrel mouth, the petal type barrel cover 4 includes the cover plate 41 for shielding the barrel mouth, the annular groove 43 of setting on the cover plate 41, the sealing groove 46 for the butt joint of barrel mouth of setting on the edge of cover plate 41, a plurality of circumferential arrangement and with the detachable connection of petal buckle 42 of barrel mouth, and the lock catch 44 for putting in the pry cover tool of setting on petal buckle 42, wherein, the sealing groove 46 is filled with sealant, and the outer edge one end of petal buckle 42 expands outward and forms the hem 45.

[0028] The design of petal type barrel cover 4 greatly simplifies the process of opening the barrel cover for the user. The user only needs to use a flathead screwdriver to insert the lock catch 44, gently pry one or more petals, and then use pliers to clamp the petal buckle 42 and turn the barrel cover to open the barrel cover in the circumferential direction. This opening method not only does not damage the structure of the barrel body 1 and the barrel cover, but also allows them to be reused multiple times. Before installing the petal type barrel cover 4, sealant is injected into the sealing groove 46 of the barrel cover, and then the barrel cover is rolled and pressed with the barrel mouth of the barrel top 2 by a capping machine, thereby achieving fastening and sealing, and enhancing the sealing performance of the barrel body 1. In addition, the outer edge of the petal buckle 42 is designed as an outwardly expanding hem 45, effectively preventing hand injuries that may occur during use.

[0029] The annular grooves 43 on the barrel cover are designed as multiple, and the diameters gradually increase from the center of the cover plate 41 outward, and they are distributed at equal intervals. This design allows the barrel cover to provide enough space to accommodate size changes when the material expands or shrinks due to temperature changes, reducing stress concentration and protecting the structural integrity of the barrel cover.

[0030] The inflating mechanism 5 and the exhausting mechanism 6 are arranged on the barrel top 2. The inflating mechanism 5 comprises a first installation slot 51, a first installation interface 52 arranged at the bottom of the slot, and a one-way inflating valve 53 connected with the interface. The exhausting mechanism 6 comprises a second installation slot 61, a second installation interface 62 arranged at the bottom of the slot, and a one-way exhausting valve 63 connected with the interface. When the air pressure in the barrel is too high, the one-way exhausting valve 63 will be automatically opened to release the pressure, and will be automatically closed when the air pressure is reduced. Such design improves the safety of the packaging barrel. The one-way exhausting valve 63 is arranged in the second installation slot 61 of the barrel top 2. Such layout helps to protect the valve during the process of carrying, using and stacking, avoids damage, and thus improves the possibility of repeated use.

[0031] The first installation slot 51 and the second installation slot 61 are both designed in a cylindrical shape, and a valve cover 7 is arranged at the slot opening. A handle 8 for opening and closing is arranged on the valve cover 7. A ventilation hole 9 is specially designed on the valve cover 7 of the second installation slot 61. The two installation slots are arranged along the center of the barrel cover symmetrically, which ensures the balance and beauty of the structure. The bottom of the valve cover 7 is provided with a thread, which is matched with and connected with the internal thread of the inner wall of the installation slot, so as to ensure the stable installation of the valve cover 7.

[0032] A plurality of reinforcing convex rings 10 are designed on the outer wall of the barrel body 1. This not only facilitates the arm of the automatic unloading vehicle to clamp the barrel body 1, prevents it from sliding down due to gravity, but also increases the wall thickness of the middle part of the barrel body, reduces the extrusion deformation of the barrel body 1 caused by mechanical operation. The existence of the reinforcing convex ring 10 also increases the friction force between the mechanical arm and the barrel during loading and unloading, so that the barrel body 1 is not easy to fall, improves the safety of carrying, and is convenient for actual operation.

[0033] The barrel bottom 3 is designed with a downwardly extending annular boss 11, the inside of which is provided with a reinforcing rib 12, and the boss is further provided with an exhaust hole 13. The existence of the reinforcing rib 12 improves the bearing capacity of the barrel body 1, and the design of the exhaust hole 13 ensures that the acetylene gas spilled from the lid of the lower barrel can overflow through the exhaust hole 13 when the barrel body 1 is stacked, avoiding the accumulation of acetylene in the cavity of the barrel bottom 3, which can cause explosion, thereby improving the overall safety.

[0034] In use, the user first opens the petal-shaped barrel cover 4, and fills in about 85% of the volume of calcium carbide. Before pressing the petal-shaped barrel cover 4, sealant is injected into the sealing groove 46 of the barrel cover, and the barrel cover is rolled and pressed with the barrel mouth of the barrel top 2 by using a capping machine. Then, the valve cover 7 is opened by the handle 8 to open the one-way exhaust valve 63, and nitrogen is filled into the barrel body 1 through the one-way inflation valve 53 to remove the residual air in the barrel in the form of protective gas, prevent calcium carbide from being decomposed by moisture to produce acetylene, and thus improve safety. The air in the barrel body 1 is discharged through the one-way exhaust valve 63, and after the air in the barrel is exhausted after a few seconds of inflation, the one-way exhaust valve 63 is closed, and the valve cover 7 is connected with the installation groove by screwing. When the air pressure in the barrel is too high, the one-way exhaust valve 63 will automatically open to release pressure, and the gas is discharged through the air hole 9. When the air pressure decreases, the one-way exhaust valve 63 will automatically close, thereby improving the safety of the packaging barrel. The one-way inflation valve 53 and the one-way exhaust valve 63 are respectively located in the first installation groove 51 and the second installation groove 61, and are provided with the valve cover 7, which helps to protect the valve during transportation, use and stacking, avoids damage, and improves the reusability of the valve.

[0035] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical scheme of the present application, and any simple modification, equivalent change and modification of the above embodiment based on the technical essence of the present application still belongs to the scope of the technical scheme of the present application.
