Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical technology, and in particular to a packaging barrel and a material extraction device. Background Technology
[0002] In the storage of special materials such as physical foaming agents with relatively low boiling points, extremely stringent requirements are placed on the sealing performance of packaging containers. Because these physical foaming agents have low boiling points and easily evaporate at room temperature or slightly higher temperatures, poor sealing of the packaging containers can lead to changes in the material composition, affecting its performance and quality, and may even pose safety hazards. Therefore, it is essential to ensure that the packaging containers have excellent sealing performance.
[0003] However, existing packaging drums have many problems in practical use. One prominent issue is the generally poor seal between the lid and the dispensing port. Many drum lids and dispensing ports have design or manufacturing defects, resulting in a poor fit and gaps. This allows outside air to easily enter the drum, contact the material, and accelerate its deterioration. Even some lids with relatively good seals still pose risks during use. Once a seal fails, employees often fail to detect it in time due to a lack of effective monitoring methods. A failed seal means outside air continuously enters the drum, severely impacting the storage performance of the material and potentially leading to deterioration, spoilage, or even rendering the material unusable.
[0004] Furthermore, existing packaging drums generally face a significant problem after fulfilling their function of storing chemical materials: because chemical materials are often highly corrosive, highly oxidizing, or contain toxic or harmful components, these substances can chemically react with or physically adhere to the inner wall of the packaging drum during storage, leading to varying degrees of corrosion and contamination. This contamination not only manifests as rust, discoloration, or scaling on the inner surface of the drum wall but can also penetrate deep into the material, causing structural damage. Cleaning contaminated packaging drums is extremely difficult; conventional high-pressure water rinsing or chemical cleaning methods are insufficient to completely remove residues, especially chemicals that have penetrated into the micropores of the material, which can easily cause secondary pollution if not handled properly. These factors collectively result in low recycling efficiency for packaging drums, requiring companies to invest significant manpower and resources in cleaning and repair, and sometimes even forcing them to be scrapped directly, increasing production costs and failing to meet the requirements of green and environmentally friendly sustainable development. Utility Model Content
[0005] In view of this, the purpose of this utility model is to overcome the shortcomings of related technologies. This utility model provides a packaging barrel and a material extraction device.
[0006] This utility model provides the following technical solution:
[0007] A packaging drum includes a drum body, an inner liner bag, a connecting seat, a sealing cap, and an anti-theft cap.
[0008] The upper end of the barrel is provided with a material extraction port; the inner liner bag is installed inside the barrel and is used to store materials; the connecting seat is threadedly installed inside the material extraction port, and the opening edge of the inner liner bag passes between the outer wall of the connecting seat and the inner wall of the material extraction port, and is clamped and fixed by the connecting seat and the material extraction port; the connecting seat has a material extraction channel, which communicates with the inside of the inner liner bag through the opening of the inner liner bag; the sealing cap is threadedly installed inside the material extraction channel; the anti-theft cap is installed on the connecting seat and seals the opening of the connecting seat away from the barrel body; the anti-theft cap is fixedly connected to the connecting seat by a buckle.
[0009] As a further improvement to the above technical solution, a disassembly groove is provided on the end face of the sealing cover opposite to the material extraction port.
[0010] As a further improvement to the above technical solution, a pull rod is provided on the end face of the anti-theft cover opposite to the sealing cover.
[0011] This utility model also provides a material extraction device for extracting materials from a packaging barrel. The material extraction device includes an extraction tube and a metal guide rod.
[0012] One end of the extraction tube is provided with a connecting part; the extraction tube passes through the extraction channel inside the barrel, and the connecting part is assembled and connected to the connecting seat; one end of the metal guide rod is hinged to the connecting part; the metal guide rod passes through the barrel, and the end of the metal guide rod away from the connecting part abuts against the inner lining bag inside the barrel.
[0013] As a further improvement to the above technical solution, a rigid connecting pipe is provided at the end of the material extraction pipe near the connecting seat, and a snap-fit platform is provided on the outer ring of the connecting pipe. The outer diameter of the snap-fit platform is larger than the diameter of the material extraction channel, and the connecting pipe and the snap-fit platform together form a connecting part.
[0014] As a further improvement to the above technical solution, the extraction tube is a flexible tube.
[0015] As a further improvement to the above technical solution, a torsion spring is provided at the hinge connection between the metal guide rod and the connecting part, and the elastic force of the torsion spring can drive the metal guide rod to deflect away from the material extraction tube.
[0016] As a further improvement to the above technical solution, at least two metal guide rods are provided along the circumferential direction of the extraction tube.
[0017] As a further improvement to the above technical solution, the end of the metal guide rod away from the connecting part is bent.
[0018] As a further improvement to the above technical solution, the connecting part is provided with a conductive element corresponding to the metal guide rod. The conductive element is electrically connected to the metal guide rod and abuts against the connecting seat.
[0019] Compared with related technologies, the beneficial effects of this utility model are:
[0020] The packaging drum provided by this utility model uses a connecting seat and a threaded connection between the connecting seat and the material extraction port of the drum body. This allows the opening of the inner liner bag inside the drum to be fixed between the connecting seat and the material extraction port, and connected to the material extraction channel. After the packaging drum has completed its chemical material storage task, only the inner liner bag needs to be removed, eliminating the need for extensive or low-cost cleaning of the drum, allowing for direct recycling and reducing material storage costs. Furthermore, by using a sealing cap to block the material extraction port and then adding an anti-theft cap on the outside of the sealing cap, the anti-theft cap provides protection for the sealing cap, reducing the probability of it loosening due to external influences. During daily handling, stacking, and storage, the packaging drum may be subjected to external forces such as collisions and compression. Without the protection of the anti-theft cap, the sealing cap may gradually loosen under these forces, leading to a decrease in sealing performance. With the anti-theft cap's protection and fixation, the sealing cap can better maintain its sealing state, greatly improving the reliability of the drum's sealing storage of materials and effectively extending the storage period.
[0021] On the other hand, the tamper-evident cover also serves as an anti-theft and status indicator. Employees can accurately determine whether the packaging drum has been opened by observing the assembly position of the tamper-evident cover relative to the connecting seat. The connecting seat is a component fixed to the drum body for installing the tamper-evident cover, and there is a specific assembly method and positional relationship between the tamper-evident cover and the connecting seat. If the packaging drum has not been opened, the tamper-evident cover will be in the normal assembly position; once the packaging drum has been opened, the position of the tamper-evident cover will change. In their daily work, employees can quickly know the status of the packaging drum by simply checking the position of the tamper-evident cover. If it is found that the packaging drum has been opened, employees can promptly check the sealing effect of the drum's extraction port, checking whether the sealing cover is still sealing well, and whether there is any damage or loosening. Through this timely inspection and handling, it can be ensured that the packaging drum always maintains a reliable storage condition for materials, avoiding adverse consequences such as material deterioration and leakage due to sealing problems.
[0022] The material extraction device provided by this utility model, when it is necessary to extract material from the packaging barrel, specifically requires first removing the tamper-evident cap from the connecting seat, then unscrewing the sealing cap from the extraction channel, and then inserting the extraction tube and the metal guide rod connected to the extraction tube into the barrel through the preset extraction channel on the connecting seat. This step requires the operator to be extremely careful to ensure that the extraction tube and the metal guide rod can smoothly enter the barrel, while avoiding unnecessary damage to the inner lining bag inside the barrel.
[0023] After completing the above insertion operation, the next step is to assemble and connect the connecting part to the connecting seat. After assembling and connecting the connecting part and the connecting seat, the connecting part also needs to be connected to the pump through the connecting piece.
[0024] After completing all connections, turn on the pump. Under the suction of the pump, the material inside the container will be gradually drawn out through the extraction pipe. During the extraction process, as the material in the container decreases, a relative negative pressure environment will form inside. Simultaneously, due to the continuous suction of the pump, this negative pressure will be further enhanced. Under this negative pressure, the inner liner bag inside the container will gradually concave inwards and inevitably move closer to the extraction pipe. If there are no appropriate support measures at this time, the inner liner bag can easily become tightly stuck to the opening of the extraction pipe as the material decreases. Once the inner liner bag is stuck to the opening of the extraction pipe, it will severely hinder the normal extraction of material, leading to a significant decrease in extraction efficiency, and may even make the extraction operation impossible to continue.
[0025] The material extraction device of this invention solves this problem by using a metal guide rod. During the extraction process, the metal guide rod provides effective support for the inner liner bag. It acts like an invisible support, maintaining a certain gap between the inner liner bag and the opening of the extraction tube, ensuring that the material can be smoothly extracted through the extraction tube, thereby guaranteeing stable extraction efficiency.
[0026] Furthermore, during the material extraction process, static electricity is easily generated due to friction between the material and components such as the extraction tube and inner liner. The accumulation of static electricity can ignite sparks, posing a significant safety hazard in scenarios involving the extraction of flammable or explosive materials. This invention utilizes a metal guide rod and connecting parts to connect the material inside the container with other external components, creating a channel for static electricity release. In this way, the static electricity generated inside the container can be promptly and effectively conducted to the outside through the metal guide rod, effectively removing static electricity from the container, greatly reducing the risk of safety accidents caused by static electricity, and ensuring safety during the material extraction process.

[0041] Combination Figure 2 , Figure 3 As shown, an embodiment of this utility model provides a packaging barrel, including a barrel body 100, an inner liner bag 120, a connecting seat 200, a sealing cap 300, and an anti-theft cap 400.
[0042] The upper end of the barrel body 100 is provided with a material extraction port 110; the inner liner bag 120 is installed inside the barrel body 100, and the inner liner bag 120 is used to store materials; the connecting seat 200 is threadedly installed inside the material extraction port 110, and the opening edge of the inner liner bag 120 passes between the outer wall of the connecting seat 200 and the inner wall of the material extraction port 110, and is clamped and fixed by the connecting seat 200 and the material extraction port 110; the connecting seat 200 is provided with a material extraction channel 210, and the material extraction channel 210 passes through the inner liner bag 120. The opening of the liner 120 communicates with the interior of the inner liner 120; the sealing cap 300 is threadedly installed in the material extraction channel 210; the anti-theft cap 400 is installed on the connecting seat 200 and seals the opening of the connecting seat 200 away from the barrel body 100; the anti-theft cap 400 is fixedly connected to the connecting seat 200 by buckles 410, and multiple buckles 410 are evenly distributed along the circumferential direction of the anti-theft cap 400 to ensure the reliability of the anti-theft cap 400 and the connecting seat 200.
[0043] The packaging barrel provided in this embodiment uses a connecting seat 200 to threadedly engage with the material extraction port 110 of the barrel body 100. This allows the opening of the inner liner bag 120 inside the barrel body 100 to be fixed between the connecting seat 200 and the material extraction port 110, and to communicate with the material extraction channel 210. This allows the packaging barrel to be directly recycled after completing the storage of chemical materials, simply by removing the inner liner bag 120 without consuming a lot of time, labor, or other costs, or at a low cost, to clean the packaging barrel, thus reducing material storage costs. Furthermore, by using a sealing cap 300 to seal the material extraction port 110, and then providing an anti-theft cap 400 on the outside of the sealing cap 300, the presence of the anti-theft cap 400 can provide a certain degree of protection for the sealing cap 300, reducing the probability of the sealing cap 300 becoming loose due to external influences. During daily handling, stacking, and storage, packaging drums may be subjected to external forces such as collisions and compression. Without the protection of the tamper-evident cap 400, the sealing cap 300 may gradually loosen under these external forces, leading to a decrease in sealing performance. However, with the tamper-evident cap 400 providing cover and fixation, the sealing cap 300 can better maintain its sealing state, greatly improving the reliability of the drum body 100 in sealing and storing materials, and effectively extending the storage period of the materials.
[0044] On the other hand, the tamper-evident cover 400 also has anti-theft and status indication functions. Employees can accurately determine whether the packaging drum has been opened by observing the assembly position of the tamper-evident cover 400 relative to the connecting seat 200. The connecting seat 200 is a component fixed to the drum body 100 for installing the tamper-evident cover 400, and there is a specific assembly method and positional relationship between the tamper-evident cover 400 and the connecting seat 200. If the packaging drum has not been opened, the tamper-evident cover 400 will be in the normal assembly position; once the packaging drum has been opened, the position of the tamper-evident cover 400 will change. In daily work, employees can quickly know the status of the packaging drum by simply checking the position of the tamper-evident cover 400. If it is found that the packaging drum has been opened, employees can promptly check the sealing effect of the material extraction port 110 of the drum body 100, and check whether the sealing cover 300 is still sealing well, and whether there is any damage or loosening. Through this timely inspection and handling, it can be ensured that the packaging drum always maintains a reliable storage state for materials, avoiding adverse consequences such as material deterioration and leakage due to sealing problems.
[0045] In some specific embodiments, the sealing cap 300 has a disassembly groove 310 on the end face opposite to the extraction port 110; for example... Figure 4 As shown, the specific shape of the disassembly groove 310 is not a common shape, but is designed to correspond to a specialized disassembly tool. In other words, only by using a specialized tool whose shape perfectly matches the disassembly groove 310 can the sealing cap 300 be operated smoothly to open the material extraction port 110 of the packaging drum. This correspondence is extremely precise; the dimensions, contours, angles, and other details of the specialized tool perfectly match the disassembly groove 310. If other non-specialized tools are used, due to the mismatch in shape, they cannot be inserted into the disassembly groove 310 at all, or even if inserted, they cannot apply effective force to open the sealing cap 300.
[0046] The purpose of this design is to effectively prevent unauthorized personnel from accidentally opening the packaging containers. In reality, unauthorized personnel may lack the relevant knowledge and experience to understand the nature and hazards of the materials stored inside the containers. If they carelessly open the material outlet 110, it could lead to a series of serious problems. For example, if the container contains flammable, explosive, toxic, or corrosive materials, accidental opening could result in material leakage, potentially causing fires, explosions, poisoning, or environmental pollution, posing a significant threat to human life and the surrounding environment.
[0047] By incorporating a disassembly slot 310 that can only be opened with specialized tools, the scope of personnel authorized to open the packaging drums is effectively limited. Only professionally trained personnel with the appropriate qualifications and knowledge, and equipped with the necessary tools, are permitted to operate the drums. This measure significantly ensures the safety of the materials stored within the packaging drums, minimizing risks during storage and guaranteeing the smooth operation of all stages of production, transportation, and storage.
[0048] In some specific embodiments, the anti-theft cover 400 has a pull rod 420 on the end face opposite to the sealing cover 300, which is used to facilitate employees to grip and pull the anti-theft cover 400 from the connecting seat 200 to remove it, making it easier for employees to operate; specifically, such as Figure 5 As shown, one end of the pull rod 420 is hinged to the anti-theft cover 400. The anti-theft cover 400 is provided with a receiving groove corresponding to the pull rod 420. When the packaging barrel is not opened, the pull rod 420 can lie flat in the receiving groove to reduce the probability of accidental pulling and ensure the safety of use in this embodiment.
[0049] like Figure 1 As shown, an embodiment of the present invention also provides a material extraction device for extracting materials from a packaging barrel. The material extraction device includes an extraction tube 500 and a metal guide rod 600.
[0050] One end of the extraction pipe 500 is provided with a connecting part; the extraction pipe 500 passes through the extraction channel 210 inside the barrel 100, and the connecting part is assembled and connected to the connecting seat 200; one end of the metal guide rod 600 is hinged to the connecting part; the metal guide rod 600 passes through the barrel 100, and the end of the metal guide rod 600 away from the connecting part abuts against the inner lining bag 120 inside the barrel 100.
[0051] The material extraction device provided in this embodiment, when it is necessary to extract the material from the packaging barrel, specifically requires first removing the anti-theft cap 400 from the connecting seat 200, then unscrewing the sealing cap 300 from the extraction channel 210, and then inserting the extraction tube 500 and the metal guide rod 600 connected to the extraction tube 500 into the barrel 100 through the preset extraction channel 210 on the connecting seat 200. This step requires the operator to be extremely careful to ensure that the extraction tube 500 and the metal guide rod 600 can smoothly enter the barrel 100, while avoiding unnecessary damage to the inner liner bag 120 inside the barrel 100.
[0052] After completing the above insertion operation, the next step is to assemble and connect the connecting part to the connecting seat 200. After assembling and connecting the connecting part and the connecting seat 200, the connecting part also needs to be connected to the pump through the connecting piece.
[0053] After all connections are completed, the material pump is turned on. Under the suction of the pump, the material inside the barrel 100 is gradually drawn out through the extraction pipe 500. During the extraction process, as the material inside the barrel 100 decreases, a relative negative pressure environment is formed inside the barrel. Simultaneously, this negative pressure is further enhanced due to the continuous suction of the pump. Under the influence of this negative pressure, the inner liner bag 120 inside the barrel 100 will gradually concave inwards and inevitably move closer to the extraction pipe 500. If there are no corresponding support measures, the inner liner bag 120 can easily become tightly stuck to the opening of the extraction pipe 500 as the material decreases. Once the inner liner bag 120 is stuck to the opening of the extraction pipe 500, it will severely hinder the normal extraction of material, leading to a significant decrease in extraction efficiency, and may even make the extraction operation impossible to continue.
[0054] The material extraction device in this embodiment solves this problem using a metal guide rod 600. During the extraction process, the metal guide rod 600 provides effective support for the inner liner bag 120. It acts like an invisible support, maintaining a certain gap between the inner liner bag 120 and the opening of the extraction tube 500, ensuring that the material can be smoothly extracted through the extraction tube 500, thereby ensuring stable extraction efficiency.
[0055] Furthermore, during the material extraction process, static electricity is easily generated due to friction between the material and components such as the extraction pipe 500 and the inner liner bag 120. The accumulation of static electricity may ignite sparks, which is undoubtedly a significant safety hazard in extraction scenarios involving flammable and explosive materials. This invention uses a metal guide rod 600 and a connecting part to connect the material inside the container with other external components, forming a channel for static electricity release. In this way, the static electricity generated inside the container can be conducted to the outside in a timely and effective manner through the metal guide rod 600, thereby effectively removing the static electricity from the container, greatly reducing the risk of safety accidents caused by static electricity, and ensuring safety during the material extraction process.
[0056] In some specific embodiments, the end of the extraction pipe 500 near the connecting seat 200 is provided with a rigid connecting pipe 510. The outer ring of the connecting pipe 510 is provided with a snap-fit platform 520. The outer diameter of the snap-fit platform 520 is larger than the diameter of the extraction channel 210. The connecting pipe 510 and the snap-fit platform 520 together form a connection part, which makes it convenient for the connecting pipe 510 to be directly hung on the connecting seat 200 through the snap-fit platform 520 after the extraction pipe 500 is inserted into the installation barrel, thereby improving the efficiency of employee operation and improving the extraction efficiency of materials.
[0057] In some specific embodiments, the extraction tube 500 is a flexible tube. During the actual operation of inserting the extraction tube 500 into the packaging drum, since the packaging drum contains an inner liner bag 120, if a rigid tube is used, it is easy to puncture the inner liner bag 120 inside the drum 100 due to improper operation or misalignment of the inner liner bag 120. Once the inner liner bag 120 is punctured, the material stored in the drum may leak out, causing not only material waste but also potential environmental pollution. In some special cases, if the material is hazardous, it may even lead to a safety accident. Using a flexible tube as the extraction tube 500 provides good flexibility and deformability, allowing it to bend and adjust appropriately according to the shape and position of the inner liner bag 120 when inserted into the packaging drum, effectively preventing puncture of the inner liner bag 120 and ensuring safety during the material extraction process in this embodiment.
[0058] Furthermore, the extraction tube 500 can specifically be a corrugated pipe. Corrugated pipes possess unique structural and performance advantages, greatly facilitating extraction operations. Firstly, when not in use, the corrugated pipe can be retracted and folded for storage. This is due to the structural characteristics of the corrugated pipe; its wall is corrugated, and under no external force, it can be compressed to reduce the spacing between the corrugations, thus achieving retraction and folding. This storage method occupies little space, making it easy to store and carry. Suitable storage locations can be easily found in warehouses, transport vehicles, or work sites, making operation very convenient. Secondly, when extracting materials from packaging drums of different depths, the corrugated pipe can be locally compressed according to actual needs. Packaging drums of different specifications may have significantly different depths. If a fixed-length extraction tube 500 is used, it may become too long or too short, affecting the extraction effect. The local compressibility of the corrugated pipe allows operators to flexibly adjust the length of the extraction tube 500 extending into the drum according to its depth. When the packaging drum is shallow, the extraction tube 500 is appropriately compressed to prevent it from being too long inside the drum and affecting operation; when the packaging drum is deep, the extraction tube 500 is ensured to have sufficient length to reach the bottom of the drum to extract materials. This flexibility allows the same embodiment to be applied to more usage scenarios, greatly improving its versatility and practicality.
[0059] In some specific embodiments, a torsion spring is provided at the hinge connection between the metal guide rod 600 and the connecting part. The elastic force of the torsion spring can drive the metal guide rod 600 to deflect away from the material extraction tube 500. In actual material extraction operations, this design becomes particularly useful when the material extraction tube 500 and the metal guide rod 600 need to be inserted into the barrel 100 through the material extraction channel 210 of the connecting seat 200. The moment the metal guide rod 600 enters the barrel 100, due to the elastic force of the torsion spring, the metal guide rod 600 will automatically open away from the material extraction tube 500. This process eliminates the need for manual adjustment by the operator, greatly improving the convenience and efficiency of the operation.
[0060] During the material extraction process, as the material inside the barrel 100 gradually decreases, a negative pressure is created inside the barrel, causing the inner liner 120 to concave inward and move closer to the extraction tube 500. At this time, the automatically expanding metal guide rod 600 acts as a stable support structure, remaining between the inner liner 120 and the extraction tube 500, preventing the inner liner 120 from sticking to the opening of the extraction tube 500 as the material decreases. If the inner liner 120 were to stick to the opening of the extraction tube 500, it would severely obstruct material extraction, leading to a significant decrease in extraction efficiency. With the support of the automatically expanding metal guide rod 600, the extraction tube 500 remains unobstructed, ensuring that the material can be smoothly extracted through the extraction tube 500, thus maintaining high extraction efficiency and guaranteeing the smooth progress of the entire extraction process.
[0061] In some specific embodiments, at least two metal guide rods 600 are provided along the circumferential direction of the extraction tube 500, which facilitates the opening of the inner lining bag 120 inside the barrel 100 from multiple directions, further ensuring the extraction efficiency of the extraction tube 500.
[0062] In some specific embodiments, the end of the metal guide rod 600 away from the connecting part is bent to reduce the probability of the metal guide rod 600 puncturing the inner lining bag 120 and ensure the safety of use in this embodiment.
[0063] In some specific embodiments, the connecting part is provided with a conductive element 610 corresponding to the metal guide rod 600. The conductive element 610 is electrically connected to the metal guide rod 600 and abuts against the connecting seat 200. During actual material storage and extraction, the material inside the inner liner bag 120 will generate static electricity due to friction with the inner liner bag 120, the extraction tube 500, and other components. If this static electricity is not discharged in time, it may cause electrostatic discharge once it accumulates to a certain extent. For some flammable and explosive materials, this is undoubtedly a huge safety hazard and may cause a fire or even an explosion.
[0064] The design in this embodiment allows the static electricity carried by the material inside the inner liner bag 120 to be conducted to the ground via the metal guide rod 600, conductive component 610, metal connector 200, and packaging drum, forming a precise conductive path. The ground can be considered a giant static electricity "container," capable of holding a large amount of charge without causing a voltage increase. Through this conductive path, static electricity in the material can be reliably discharged, minimizing the risk of static electricity accumulation and effectively ensuring the safety of material storage and retrieval processes, thus avoiding various safety accidents caused by static electricity.
