Description

Technical Field

[0001] This utility model relates to the field of chemical drum technology, and in particular to a corrosion-resistant stacking drum for chemical use. Background Technology

[0002] Chemical drums, as core containers for the storage and transportation of hazardous chemicals, have become an indispensable basic equipment in the chemical industry chain. Their applications cover high-risk and high-requirement fields such as petroleum refining, pharmaceutical synthesis, pesticide formulation, dye intermediates, and electronic chemicals, and they must meet the requirements for sealed storage and safe transfer of various hazardous chemicals, including those with strong corrosiveness, high toxicity, and high volatility.

[0003] Existing chemical drums exhibit two major drawbacks during stacking and transportation: First, their single-layer structure cannot effectively prevent the penetration of highly corrosive media, and the inner wall is susceptible to chemical corrosion and failure. Second, the drums lack internal flow guidance designs, and tilting during stacking or transportation can easily cause significant liquid sloshing, increasing the risk of residue and splashing, and potentially damaging the drum structure due to turbulent impact. These problems directly threaten the safety of chemical storage, necessitating structural innovation to improve overall performance. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a corrosion-resistant stacking barrel for chemical applications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chemical corrosion-resistant stacking barrel includes a barrel body, which is composed of an inner layer, a barrier layer, a structural layer, and an outer layer. A feed pipe communicating with the interior of the barrel body is fixedly connected to the top of the barrel body, and a barrel cover is threadedly connected to the feed pipe. A fixing rod is fixedly connected to the top of the barrel body, and four corrugated plates are circumferentially fixedly connected to the outer wall of the fixing rod. The other end of each corrugated plate is fixedly connected to the inner wall of the barrel body.

[0007] As a further improvement of this utility model, a handle is fixedly connected to the top of the barrel at the feed pipe, and the handle is arranged adjacent to the feed pipe in the length direction.

[0008] As a further improvement of this utility model, support protrusions are fixedly connected to both sides of the bottom of the barrel, and the two support protrusions form a stacking groove.

[0009] As a further improvement of this utility model, positioning grooves are provided on both sides of the two supporting protrusions, and positioning protrusions that cooperate with the positioning grooves are provided at the four corners of the top of the barrel.

[0010] As a further improvement of this utility model, the handle, feed pipe and barrel lid are all configured to cooperate with the stacking groove.

[0011] As a further improvement of this utility model, multiple slots are sequentially opened through the multiple waveform plates.

[0012] The beneficial effects of this utility model are:

[0013] By employing a multi-layered structure consisting of a polytetrafluoroethylene inner layer, an ethylene-vinyl alcohol copolymer barrier layer, a linear low-density polyethylene structural layer, and a high-density polyethylene outer layer, chemical corrosion is effectively prevented and overall strength is improved. The bottom support protrusions cooperate with the stacking groove, and the positioning protrusions engage with the positioning groove, achieving stable stacking and preventing horizontal displacement. The four corrugated plates distributed circumferentially at the top of the barrel disperse the kinetic energy of liquid flow through their periodic undulation structure, and together with the controllable liquid channel formed by the groove opening, significantly reduce the amplitude of liquid surface sloshing caused by tilting during stacking or transportation, suppress the formation of large-scale turbulence, avoid liquid residue accumulation, and reduce the risk of chemical splashing. The size matching design of the handle, feed pipe, and barrel lid with the stacking groove ensures that the top components do not exceed the range during stacking, further improving stacking stability and operational safety.

[0014] This invention comprehensively improves the strength of the container, the stability of the stacking, and the operational safety by using a multi-layer structure to prevent corrosion, bottom support and positioning locking to stabilize the stacking, corrugated plates to disperse kinetic energy and suppress liquid surface sloshing, and the size matching of components such as handles to ensure stacking stability, while reducing the risk of chemical splashing.

[0020] 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.

[0021] Figures 1-4 A chemical corrosion-resistant stacking drum includes a drum body 1, which serves as the main storage unit for chemicals. Supporting protrusions 9 are fixedly connected to both sides of the bottom of the drum body 1. The supporting protrusions 9 support the drum body 1 and distribute stacking pressure. Two supporting protrusions 9 form a stacking groove 11. Positioning grooves 10 are provided on both sides of the two supporting protrusions 9. Positioning protrusions 3, which cooperate with the positioning grooves 10, are provided at the four corners of the top of the drum body 1. The positioning grooves 10 cooperate with the positioning protrusions 3 to limit the horizontal displacement of adjacent drum bodies 1. The drum body 1 consists of an inner layer 12 and a barrier layer 13. The barrel 1 consists of a structural layer 14 and an outer layer 15, made of polytetrafluoroethylene, ethylene-vinyl alcohol copolymer, linear low-density polyethylene, and high-density polyethylene, respectively. The inner layer 12 is in direct contact with chemicals, the barrier layer 13 is used to prevent corrosive substances from penetrating, the structural layer 14 provides compressive strength, and the outer layer 15 protects the internal structure from external impacts. A feed pipe 4, communicating with the interior, is fixedly connected to the top of the barrel 1. The feed pipe 4 is used to inject or discharge chemicals into the barrel 1. A barrel cover 5 is threaded onto the feed pipe 4, and the barrel cover 5 seals the feed pipe 1 with threads. The feed pipe 4 prevents chemical leakage and the entry of external contaminants. A handle 2 is fixedly connected to the top of the barrel 1 at the feed pipe 4. The handle 2 is used for moving the barrel 1 and is positioned adjacent to the feed pipe 4 to optimize operating space. The handle 2, feed pipe 4, and barrel lid 5 are all designed to fit into the stacking groove 11. The dimensions of the stacking groove 11 are compatible with the shapes of the handle 2, feed pipe 4, and barrel lid 5, ensuring that the top components do not exceed the range of the stacking groove 11 during stacking. A fixing rod 6 is fixedly connected to the top of the barrel 1. Four rods are circumferentially fixed to the outer wall of the fixing rod 6. The periodic undulating structure of the corrugated plate 7 can disperse the kinetic energy of the liquid flow and reduce the amplitude of liquid surface sloshing caused by tilting during stacking or transportation. Its multi-level resistance barrier design can effectively suppress the formation of large-scale turbulence. Multiple slots 8 are sequentially opened on multiple corrugated plates 7. The slots 8 form controllable liquid channels on the surface of the corrugated plate 7, which allow low-speed flow to balance the internal pressure and further dissipate residual kinetic energy through the narrow path to avoid liquid residue accumulation. The other end of each corrugated plate 7 is fixedly connected to the inner wall of the barrel 1.

[0022] When using this invention, first unscrew the lid 5 and inject the chemicals through the feed pipe 4. After filling, tighten the lid 5 again to seal. When stacking, engage the support protrusion 9 of the lower barrel 1 with the stacking groove 11 of the upper barrel 1, and embed the positioning protrusion 3 into the positioning groove 10 to fix the position and prevent horizontal displacement. When handling, hold the handle 2 to keep the barrel 1 upright and avoid tilting, which could cause the liquid to shake violently. The corrugated plate 7 can suppress residual fluctuations. During use, the sealing of the lid 5 and the structural integrity of the barrel 1 should be checked regularly to ensure the safe storage of chemicals.

[0023] 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.
