Description

Technical Field

[0001] This utility model relates to the field of chemical drum technology, and in particular to a chemical drum that is easy to stack. Background Technology

[0002] As the core carrier for the storage and transportation of chemical raw materials, the ease of use, stacking stability, and structural strength of chemical drums directly affect the efficiency and safety of chemical production processes. In the warehousing and transportation processes of chemical enterprises, stacking chemical drums is a common practice to save space and reduce logistics costs; therefore, stacking stability has become one of the key indicators in the structural design of chemical drums.

[0003] Most chemical drums in existing technologies are traditional cylindrical or square structures, which generally present the following problems when stacking: First, they lack specialized positioning and fitting structures, making it easy for relative sliding to occur between upper and lower layers of chemical drums. Especially when subjected to bumps during transportation or external impacts, the entire stack is prone to collapse, which may not only cause chemical raw material leakage and safety accidents, but also increase cargo damage and handling costs. Second, the edges of chemical drums are mostly right-angled structures, which can easily scratch operators or adjacent drums during handling and stacking. Moreover, stress concentration at right angles makes them prone to damage and cracking upon impact, affecting the sealing performance and service life of the drums. At the same time, the side wall structure of the drums is simple and the overall strength is insufficient. They are prone to permanent deformation when stacked under pressure or accidentally impacted, further reducing stacking safety.

[0004] Therefore, it is necessary to design a chemical drum that is easy to stack to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by protruding a chemical drum that is easy to stack. The invention facilitates stable stacking of the chemical drums through the design of protrusions and grooves. Furthermore, the placement of positioning posts and plates facilitates rapid positioning of the protrusions and grooves. The positioning plates can also be stored away to prevent obstruction and ensure smooth pouring of chemical raw materials. The grooves enhance the strength of the chemical drums, preventing deformation from impacts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stackable chemical drum includes a drum body, a handle fixedly connected to the upper end of the drum body, and four protrusions fixedly connected to the upper end of the drum body. The four protrusions are conical, and their cross-sectional areas decrease from top to bottom. The four protrusions are located at the four corners of the upper part of the drum body. A recessed area is provided on the upper part of the drum body, and the opening of the drum body and the handle are both located in the recessed area. The lower end of the drum body is provided with four insertion holes corresponding to the protrusions.

[0008] Preferably, all edges of the barrel are rounded; at the rounded corners of the side of the barrel, two grooves are provided circumferentially along the side; the grooves create a protrusion between two adjacent grooves on the side of the barrel.

[0009] Preferably, the upper end of the barrel is fixedly connected with multiple positioning posts, and the adjacent sides of every two corresponding positioning posts are inclined surfaces. Multiple arc-shaped grooves are provided in the lower areas of the left and right sides of the barrel.

[0010] Preferably, it also includes a side lifting assembly, which includes multiple fixing blocks fixedly connected to the inner walls of the front and rear sides of the barrel. Each fixing block is provided with a through hole, and a screw is slidably connected in every two cooperating through holes. A nut is threaded onto each of the two screws.

[0011] Preferably, square blocks are fixedly connected to both the front and rear sides of the barrel, and adjacent sides of every two mating square blocks are rotatably connected to a rotating shaft, with a positioning plate fixedly connected to each of the two rotating shafts.

[0012] Preferably, the positioning plate is provided with a fixing hole that mates with the screw.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. Compared with existing technologies, the stacking positioning is more accurate and the stability is stronger: The conical protrusions at the four corners of the upper end of the barrel and the corresponding insertion holes at the lower end form a fitting structure. With the guide effect of the inclined surface of the positioning post, the upper and lower barrels can be quickly aligned, avoiding the trouble of repeated adjustments when stacking traditional chemical barrels; The design of the protrusion cross-sectional area decreasing from top to bottom, the setting of arc groove and positioning plate effectively prevents the barrel from sliding laterally after stacking. Even in the case of bumpy transportation, the overall stability of the stack can be maintained, reducing the risk of raw material leakage.

[0015] 2. Compared with existing technologies, the structure is stronger and safer to use: The rounded corners of all edges of the barrel avoid the risk of scratching operators due to the traditional right-angled edges, and also disperse stress concentration, reducing the probability of impact damage; the groove design of the rounded corners on the sides optimizes the stress structure of the barrel side wall while forming protrusions, improving impact resistance and pressure bearing capacity, solving the problem of easy deformation of existing chemical barrels when stacked under pressure, and extending the service life of the barrel;

[0016] 3. Compared with existing technologies, the rotating positioning plate cooperates with the screw through the fixing hole, which not only assists in accurate positioning during stacking, but also allows it to be rotated and stored when not in use, avoiding the problem of traditional positioning structures blocking unloading. In addition, the handle assembly can not only be used for the daily handling of chemical drums, but also for limiting the positioning plate that has been rotated to the top.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figures 1-2 A stackable chemical drum includes a drum body 1, which serves as the core load-bearing component for containing various chemical raw materials. The drum body 1 is made of high-strength, corrosion-resistant material, adaptable to the storage environment of chemical raw materials and preventing damage to the drum body 1 due to corrosion. A handle is fixedly connected to the upper end of the drum body 1, using an integrated injection molding process to ensure connection strength. Workers can easily move the empty or lightly loaded drum body 1 using the handle, improving the convenience of single-person operation. Four conical protrusions 2 are fixedly connected to the upper end of the drum body 1. The shape of the protrusion 2, with its cross-sectional area decreasing from top to bottom, provides a guiding function, facilitating precise alignment with the insertion holes 10 during subsequent stacking. The four protrusions 2 are located at the four corners of the top of the barrel 1. This corner distribution structure ensures more even force distribution on the barrel 1 during stacking, preventing excessive local force that could cause stacking deviation. A recessed area is provided on the top of the barrel 1, with the opening and handle located within this area. The lower end of the barrel 1 has four insertion holes 10 corresponding to the protrusions 2. The inner diameter of the insertion holes 10 is the same as the maximum outer diameter of the protrusions 2, ensuring that the protrusions 2 can be smoothly inserted into the holes.

[0025] All edges of the barrel 1 are rounded to eliminate sharp corners, preventing workers from being scratched during handling and stacking, thus improving operational safety. This also reduces wear on the edges during collisions, extending the service life of the barrel 1. At the rounded corners on the side of the barrel 1, two grooves 3 are spaced apart circumferentially along the side. The grooves 3 create protrusions between adjacent grooves 3 on the side of the barrel 1, which enhance the structural rigidity of the side of the barrel 1 and reduce deformation caused by its own weight or external pressure after the barrel 1 is filled with raw materials.

[0026] The functional principle of this utility model can be explained through the following operation: First, the stacking and positioning function requires that the bottom barrel 1 be placed on a flat storage or transportation platform before stacking to ensure that the barrel 1 is in a horizontal state. When stacking the upper barrels 1, the four insertion holes 10 at the bottom of the upper barrel 1 must be precisely aligned with the four protrusions 2 at the top of the bottom barrel 1. Since the protrusions 2 are conical and their cross-sectional areas decrease from top to bottom, the insertion holes 10 can be inserted into the protrusions 2 more smoothly, achieving rapid positioning.

[0027] Example 2

[0028] Reference Figures 3-4 The difference between this embodiment and embodiment 1 is that multiple positioning posts 4 are fixedly connected to the upper end of the barrel 1. The adjacent sides of every two corresponding positioning posts 4 are inclined surfaces with an inclination angle of 30°-45°. This inclined surface structure can play a guiding role when stacking. If the upper barrel 1 is slightly offset when placed, the inclined surface will generate a lateral thrust on the upper barrel 1, guiding it to automatically adjust to the correct position, further improving the stacking accuracy. Multiple arc-shaped grooves are provided in the lower areas of the left and right sides of the barrel 1. After stacking, the positioning posts 4 are located in the arc-shaped grooves to limit the stacked chemical barrels and prevent relative displacement between the front and rear sides of the chemical barrels.

[0029] The system also includes a side-lifting assembly, which consists of multiple fixing blocks 7 fixedly connected to the inner walls of the front and rear sides of the barrel 1. Each fixing block 7 has a through hole, and a screw 9 is slidably connected to every two mating through holes. Nuts 8 are threaded onto both screws 9. Square blocks are fixedly connected to the front and rear sides of the barrel 1. A rotating shaft is rotatably connected to the adjacent sides of every two mating square blocks. Positioning plates 5 are fixedly connected to both rotating shafts. The positioning plates 5 have fixing holes 6 that mate with the screws 9. When the positioning plates 5 are needed, they can be rotated upwards to align the fixing holes 6 with the through holes of the fixing blocks 7. Then, the screws 9 are passed through them, and finally, the nuts 8 are tightened to fix the positioning plates 5. This limits the front and rear position of the upper barrel 1 during stacking, improving stacking stability.

[0030] In this embodiment, multiple positioning posts 4 at the upper end of the barrel 1 further assist in alignment. The adjacent sides of every two corresponding positioning posts 4 are inclined surfaces, which can guide the upper barrel 1 to adjust its position during the stacking process and avoid displacement. Finally, through the cooperation of the protrusion 2 and the insertion hole 10 and the assistance of the positioning posts 4, the verticality and stability of the multi-layer barrel 1 are ensured, and the stacking is prevented from tilting and collapsing.

[0031] Before stacking, first rotate nut 8 to separate it from screw 9. After pulling out screw 9, rotate the two positioning plates 5 to the top, then pass screw 9 through the through hole and fixing hole 6, and then tighten nut 8 to fix positioning plate 5. This allows positioning plate 5 to position the front and rear of chemical drums during stacking, and can further prevent chemical drums from tipping over after stacking. After the chemical drums are stacked, multiple positioning posts 4 will be located in multiple arc-shaped grooves of the upper chemical drum, further limiting the position of the upper chemical drum.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
