Description

Technical Field

[0001] This application relates to the field of flammable and explosive dust handling, and in particular to an inerting powder container. Background Technology

[0002] With the continuous development of the economy, the scale of industrial fields such as laser processing, magnesium and aluminum processing, plastics, organic synthesis, powder metallurgy, and food processing is constantly expanding. The types of dust generated during the production process are increasing and the amount used is increasing dramatically, leading to a significant increase in the probability of dust accumulation in the production environment and a significant increase in the potential danger of dust explosions. Therefore, preventing dust explosion accidents has become a key link in the safe production of the above-mentioned industries. In dust explosion prevention work, inerting powder plays an important role. Inerting powder is a functional powder material used to reduce the oxygen concentration in the dust environment and inhibit dust combustion and explosion. When used in conjunction with inerting equipment, inerting powder can effectively control the safety risks of the dust environment and ensure the safety of the production process.

[0003] In related technologies, the main packaging method for inerting powder on the market is bag packaging. This type of packaging is widely used for the storage and transportation of inerting powder after production. When using it, operators need to manually load the inerting powder from the bag into the inerting equipment.

[0004] However, existing bag packaging methods have significant limitations. The sealing effect of bag packaging is poor, and its ability to isolate moisture in the air is limited. As a result, the inerting powder easily absorbs moisture and becomes damp during storage. Damp inerting powder will significantly reduce its inerting performance and make it difficult to achieve the expected dust explosion prevention effect. Furthermore, when loading inerting powder into the inerting equipment, the bag packaging must be opened before the powder is poured out, which easily generates a lot of dust during the entire operation. This dust will pollute the workshop production environment and affect the health of the operators. Utility Model Content

[0005] To address the aforementioned issues, this application provides an inerting powder container.

[0006] The inerting powder container provided in this application adopts the following technical solution: it includes a barrel body, a first sealing element, a filter element, and a drying element. The barrel body includes a barrel body, a powder barrel opening, and a drying element storage section. The powder barrel opening and the drying element storage section are respectively disposed at both ends of the barrel body. The drying element storage section is connected to the inside and outside of the barrel body. The first sealing element covers the powder barrel opening, the filter element covers the drying element storage section, and the drying element is disposed on the filter element.

[0007] By adopting the above technical solution, the powder container opening at one end of the container is covered by a first sealing element, which can form a seal on the powder container opening, reducing the intrusion of external moisture and impurities during storage. The drying element storage section at the other end of the container provides a dedicated space for the drying element. The drying element is placed on a filter element covering the drying element storage section. The filter element is both breathable to ensure that the drying element can fully exert its drying effect on the inert powder in the container, and effectively isolates the drying element from the inert powder, reducing the probability of the drying element and inert powder mixing and affecting the powder performance. The drying effect of the drying element and the sealing effect of the first sealing element work together to reduce the inert powder in the container. The inerting powder absorbs moisture during storage, thus extending its shelf life and ensuring its effectiveness. Simultaneously, the drying unit connects the inside and outside of the container, balancing the internal and external air pressure. When the inerting powder container is placed in the designated position on the inerting equipment, the pressure balance allows the inerting powder to flow more smoothly and automatically into the equipment. The surface of the powder container opening contacts the inerting equipment, isolating the powder inside the container as it flows in, significantly reducing dust levels in the workshop and minimizing the adverse health effects of dust inhaled by operators.

[0008] Preferably, a locking element is provided on the edge of the powder bucket opening.

[0009] By adopting the above technical solution, a locking device is set on the edge of the powder barrel opening, which can firmly lock the barrel to the inerting equipment when the inerting powder container is placed in the designated position of the inerting equipment. This reduces the occurrence of inerting powder overflowing to the outside when it flows from the powder barrel opening into the inerting equipment, thereby reducing dust generation in the workshop and reducing the impact on the health of operators.

[0010] Preferably, the drying component storage section is a cavity formed by a recess in the barrel body at one end away from the powder barrel opening, and the cavity communicates with the interior of the barrel body.

[0011] By adopting the above technical solution, the inwardly recessed chamber structure can form a stable limit for the drying component, allowing the drying component to continuously perform its drying function. The chamber is connected to the inside of the barrel, allowing the drying component to directly act on the inerting powder inside the barrel, fully exerting the drying and adsorption effect, reducing the situation where the inerting powder absorbs moisture from the air and becomes damp during storage, ensuring the inerting performance of the inerting powder, and extending the shelf life of the inerting powder.

[0012] Preferably, the chamber is provided with a plurality of vent holes, and the filter element is disposed on the vent holes.

[0013] By adopting the above technical solution, the vent connects the chamber to the inside of the container, allowing the drying effect generated by the drying element in the chamber to be evenly transferred to the inside of the container through the vent. This fully absorbs moisture from the air inside the container, effectively reducing the chance of the inerting powder becoming damp during storage, thus ensuring the inerting performance of the inerting powder and extending its shelf life. At the same time, the filter element covers the vent. The filter element is both breathable, allowing moisture to enter the chamber through the vent and be absorbed by the drying element, and also isolates the drying element inside the chamber, reducing the chance of the drying element entering the inside of the container through the vent and mixing with the inerting powder, thus ensuring the purity of the inerting powder.

[0014] Preferably, it also includes a second seal, which covers the side of the barrel body away from the powder barrel opening.

[0015] By adopting the above technical solution, the second sealing element covers the side of the barrel away from the powder barrel opening, which can directly seal the desiccant stored in the recessed chamber inside the chamber. This can prevent external dust and impurities from entering the chamber and contaminating the desiccant, ensuring that the drying efficiency of the desiccant is not affected by the external environment and will not fail prematurely.

[0016] Preferably, the drying component storage section is provided with a handle, and the handle is fixedly connected to the barrel body.

[0017] By adopting the above technical solution, the handle provides reliable grip support for the operator, allowing the operator to easily grasp the inerting powder container, facilitate the transfer and handling of the inerting powder container during transportation, and align the inerting powder container with the designated position on the inerting equipment for installation and positioning.

[0018] Preferably, the second seal is disposed on the surface of the handle and the barrel body.

[0019] By adopting the above technical solution, when not in use, the second seal stably covers the surface of the handle and the barrel, which can seal the desiccant in the chamber, preventing the intrusion of external dust and moisture, and ensuring that the desiccant always maintains its drying efficiency. When entering the use process, since the second seal is attached to the surface of the handle and the barrel, the operator can easily tear off the second seal completely. At this time, the vent of the desiccant storage part can be connected to the outside. Then, the operator can directly use the handle fixedly connected to the barrel to easily pick up the inerting powder container and accurately place it into the designated position of the inerting equipment.

[0020] Preferably, the side wall of the barrel is fixedly provided with multiple reinforcing ribs.

[0021] By adopting the above technical solution, multiple reinforcing ribs can significantly enhance the structural rigidity and load-bearing capacity of the barrel sidewall, reduce the deformation of the barrel due to external collisions, squeezing or its own gravity during storage, stacking, transportation and handling, and further reduce the situation where the first seal, second seal and filter are misaligned due to barrel deformation, resulting in seal failure and affecting the sealing performance of inerting powder storage.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The powder container opening at one end of the container is covered by a first sealing element to form a seal, reducing the intrusion of external moisture and impurities during storage. The drying element storage section at the other end provides a dedicated space for the drying element, which is placed on a filter element covering this storage section. The filter element combines air permeability and isolation, ensuring that the drying element can fully exert its drying effect on the inerting powder in the container, while reducing the problem of the drying element and the inerting powder getting mixed up. The drying element and the first sealing element work together to reduce the moisture absorption of the inerting powder during storage, extend the shelf life, and ensure effectiveness. At the same time, the drying element storage section connects the inside and outside of the container to balance the internal and external air pressure. When the inerting powder container is placed in the designated position of the inerting equipment and the first sealing element is punctured, the air pressure balance can promote the inerting powder to flow more smoothly and automatically into the inerting equipment. The surface of the powder container opening is in contact with the inerting equipment, isolating the inerting powder inside the container while the powder flows in, greatly reducing the amount of dust in the workshop, thereby reducing the adverse effects on the health of operators caused by the inhalation of dust.

Second sealing element; Detailed Implementation The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses an inerting powder container. (Refer to...) Figure 1 The device includes a barrel body 1, which is used to store inert powder. Specifically, the barrel body 1 includes a barrel body 11 and a powder barrel opening 12. The barrel body 11 is shaped as a cylinder and a cone shape fixedly connected. The powder barrel opening 12 is located at the cone-shaped end of the barrel body 11. The powder barrel opening 12 includes a connecting part 121 and an outwardly turned surface 122. One end of the connecting part 121 is fixedly connected to the cone-shaped end of the barrel body 11. The connecting part 121 is a short cylindrical section. The short cylindrical section can enhance the structural stability of the powder barrel opening 12. The outwardly turned surface 122 can form a better sealing effect between the powder barrel opening 12 and the inertization equipment, and at the same time, it can make the inert powder flow out of the barrel body 11 smoother.

[0030] Reference Figure 2 and Figure 3 In addition, a locking member 1221 is provided on the edge of the outward-turned surface 122, which can firmly lock the barrel 1 to the inerting equipment when the inerting powder barrel container is placed in the designated position of the inerting equipment. At the same time, this embodiment also includes a first sealing member 2, which is a sealing film. The sealing film is bonded and fixed to the outward-turned surface 122. The first sealing member 2 covers and seals the opening 12 of the powder barrel. In use, the inerting powder barrel container is placed in the designated position of the inerting equipment, and the barrel body 11 is rotated to lock and fix the inerting powder barrel container to the inerting equipment through the locking member 1221. Then the inerting equipment will automatically puncture the sealing film at the opening 12 of the powder barrel, and the inerting powder in the barrel body 11 will automatically flow into the inerting equipment.

[0031] Furthermore, the outward-turned surface 122 contacts the inerting equipment, effectively isolating the inerting powder inside the barrel 1 during the inerting powder flow into the inerting equipment, significantly reducing the amount of dust in the workshop. At the same time, the locking element 1221 set on the edge of the outward-turned surface 122 can firmly lock the barrel 1 and the inerting equipment when the inerting powder barrel is placed in the designated position of the inerting equipment, reducing the overflow of inerting powder to the outside when it flows in, thereby further reducing the generation of dust in the workshop and significantly reducing the adverse effects on the health of operators who inhale dust.

[0032] Reference Figure 4 and Figure 5 Furthermore, the drying component storage section is a chamber 13 formed by the recess of the end of the barrel 11 away from the powder barrel opening 12. The chamber 13 is connected to the interior of the barrel 11. The chamber 13 is provided with a plurality of vent holes 131, which connect the interior area of ​​the barrel 11 and the exterior area of ​​the barrel 11.

[0033] Meanwhile, this embodiment also includes a filter element 3 and a drying element 4. The filter element 3 is bonded to the upper surface of the chamber 13 and covers multiple vent holes 131. In this embodiment, the filter element 3 is made of expanded polytetrafluoroethylene (ePTFE) polymer membrane. The ePTFE polymer membrane is formed into a three-dimensional mesh micropore through a special stretching process. The pore size can be controlled within the range of 0.1-10 micrometers. This structure allows air, water vapor, etc. to pass through freely, but can effectively block larger particles.

[0034] Furthermore, the drying element 4 is disposed on the filter element 3. In this embodiment, the drying element 4 is provided with a desiccant composed of calcium chloride. The desiccant composed of calcium chloride is suitable for high humidity environments and does not react with the inerting powder, and can quickly reduce the ambient humidity.

[0035] This explains that the chamber 13 formed by the inward indentation at the end of the barrel 11 away from the powder barrel opening 12 serves as a storage area for the drying components 4. This storage area provides a dedicated storage space for the drying components 4, providing stable positioning for them and ensuring their continuous drying function. Furthermore, the chamber 13 allows communication with the interior and exterior of the barrel 11 through multiple ventilation holes 131, enabling moisture inside the barrel to flow into the chamber 13. Simultaneously, the filter element 3, which covers the ventilation holes 131 and uses an expanded polytetrafluoroethylene (ePTFE) polymer membrane, with its 0.1-10 micrometer three-dimensional mesh microporous structure, allows air and water vapor to pass freely, ensuring that moisture smoothly enters the chamber 13 and contacts the drying components 4. It also effectively blocks larger particles, isolating the drying components 4 in the chamber 13 from the inerting powder inside the barrel 11, reducing the mixing of the two and minimizing the impact on the purity of the inerting powder.

[0036] Furthermore, the drying element 4, which is composed of calcium chloride and is installed on the filter element 3, is not only suitable for high humidity environments and can reduce the humidity in the chamber 13 and the barrel, but also will not react with the inerting powder. It can stably perform the drying function, reduce the situation where the inerting powder absorbs moisture and becomes damp during storage, thereby ensuring the inerting performance of the inerting powder and extending the shelf life.

[0037] Meanwhile, when the inerting powder container is placed in the designated position of the inerting equipment, the air pressure balance achieved by the vent 131 connecting the inside and outside of the container body 11 can also cause the inerting powder to flow more smoothly and automatically into the inerting equipment after the inerting powder container is placed in the inerting equipment and the seal of the powder container opening 12 is punctured.

[0038] Furthermore, this embodiment also includes a handle 5, which is disposed on the drying component storage section and is fixedly connected to the barrel body 11 at both ends. The handle 5 is shaped as a straight rod and divides the opening of the chamber 13 into two areas. The handle 5 provides reliable grip support for the operator, allowing the operator to easily grasp the inerting powder barrel container for transfer and handling during transportation and for aligning the inerting powder barrel container with the designated position of the inerting equipment for installation and positioning.

[0039] Meanwhile, this embodiment also includes a second sealing element 6, which is also set as a sealing film. In this embodiment, there are two sealing films. Both sealing films are bonded and fixed to the upper surface of the handle 5 and the barrel body 11. The two sealing films cover the two areas of the opening of the chamber 13. When not in use, the second sealing element 6 is stably bonded to the surface of the handle 5 and the barrel body 1, which can seal the desiccant in the chamber 13, prevent external dust and moisture from entering, and ensure that the desiccant always maintains its drying efficiency.

[0040] Furthermore, when entering the usage process, the operator can easily tear open the second seal 6 completely, at which point the vent 131 of the drying component storage part can be connected to the outside. Then, the operator can directly use the handle 5, which is fixedly connected to the barrel 1, to easily pick up the inerting powder barrel container and accurately place it into the designated position of the inerting equipment.

[0041] Meanwhile, the side wall of the barrel 11 is provided with multiple reinforcing ribs 111. The reinforcing ribs 111 are in the shape of a ring. The multiple reinforcing ribs 111 are fixedly arranged along the side wall of the barrel 11. The multiple reinforcing ribs 111 can significantly enhance the structural rigidity and load-bearing capacity of the side wall of the barrel 11, reduce the deformation of the barrel 11 due to external collision, squeezing or its own gravity during storage, stacking, transportation and handling, and further reduce the situation where the first sealing element 2, the second sealing element 6 and the filter element 3 are displaced due to the deformation of the barrel 11, resulting in sealing failure and affecting the sealing performance of the inerting powder storage.

[0042] The implementation principle of an inerting powder container according to an embodiment of this application is as follows: During the storage stage, the container body 1 is mainly composed of a cylindrical and conical body 11. The powder container opening 12 at one end of the conical shape is reinforced with a structure of a short cylindrical section and an outwardly flared plane 122. The first sealing element 2 on the outwardly flared plane 122 is a sealing film, which seals the powder container opening 12 and prevents external moisture and impurities from entering, thus protecting the inerting powder inside the container. The cavity 13 formed by the inward indentation at the end of the container body 11 away from the powder container opening 12 serves as a desiccant storage area. The cavity 13 contains a desiccant 4 composed of calcium chloride. The desiccant 4 is suitable for high humidity environments and does not react with the inerting powder. Multiple vent holes 131 on the cavity 13 connect the inside and outside of the container body 11 and cover the vent holes 1. The filter element 3 of 31 is an expanded polytetrafluoroethylene (ePTFE) polymer membrane. This polymer membrane has a three-dimensional network microporous structure of 0.1-10 micrometers, which allows water vapor to pass through while blocking particles, so that the desiccant 4 and the inerting powder will not be confused. At the same time, the opening of the chamber 13 is covered by a second sealing element 6 that is bonded to the handle 5 and the barrel body 11. The second sealing element 6 is also a sealing membrane and there are two of them. Both sealing membranes are bonded and fixed to the upper surface of the handle 5 and the barrel body 11, respectively covering the two areas of the opening of the chamber 13. This can seal the desiccant in the chamber 13, prevent the intrusion of external dust and moisture, ensure that the desiccant always maintains its drying efficiency, and thus achieve long-term moisture-proof storage of the inerting powder, extend the shelf life of the inerting powder and ensure its inerting performance.

[0043] During use, the operator can easily tear open the second seal 6 completely, allowing the vent 131 of the dryer storage section to connect with the outside. Then, the operator can easily grip the inerting powder container using the straight handle 5 fixedly connected to the barrel body 11. This handle 5, located on the dryer storage section, is fixedly connected to the barrel body 11 at both ends and divides the opening of the chamber 13 into two areas, providing reliable grip support for the operator. This facilitates the transport and transfer of the inerting powder container and its alignment with the designated position on the inerting equipment. After transferring the inerting powder container to the designated position on the inerting equipment, the barrel body 11 is rotated, and the locking element 1221 on the edge of the outward-facing plane 122 of the powder container opening 12 secures the inerting powder container. The device is securely locked to the inerting equipment. At this time, the outward-turned surface 122 is in close contact with the inerting equipment to form a seal. Subsequently, the inerting equipment automatically punctures the first seal 2, and the air pressure balance formed by the vent 131 of the chamber 13 and the inside and outside of the barrel 11 is achieved. With the help of the cylindrical and conical flow guiding structure of the barrel 11, the inerting powder in the barrel flows smoothly and automatically into the inerting equipment along the powder barrel opening 12. Moreover, the sealing and locking effect of the outward-turned surface 122 and the locking part 1221 can isolate the inerting powder inside the barrel 1, reduce the dust generated by the powder overflow during feeding, ensure the convenience of operation, and reduce the adverse effects of dust on the health of operators. Ultimately, the safe and efficient flow of inerting powder from storage to feeding is achieved.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
