Description

Technical Field

[0001] This utility model relates to the field of flange barrel technology, specifically a flange barrel for nested placement. Background Technology

[0002] Flange drums are a common container used in industrial production, logistics, and numerous storage applications for storing and transporting various liquids, powders, and granules. Their unique structural design offers numerous advantages in stacking, handling, and other operations, such as ease of mechanical handling and stable stacking, thereby effectively improving logistics efficiency and space utilization.

[0003] When flanged drums are stacked and nested, it is difficult to achieve an absolutely flat and tight fit between the drums and between the cover and the drum. Under the influence of external pressure, vibration, or temperature changes, tiny gaps can easily appear. Although these gaps may seem insignificant, they can lead to serious consequences for materials with extremely high sealing requirements. For example, in the chemical industry, many chemical raw materials are volatile, corrosive, or flammable and explosive. If the flanged drums are not properly sealed, these harmful substances may leak out through the gaps, not only polluting the surrounding environment and endangering the health of operators, but also potentially causing serious safety accidents such as fires and explosions. In the food and pharmaceutical industries, poor sealing can also lead to contamination of materials by external dust, bacteria, and moisture, affecting product quality and safety, and even causing product spoilage, resulting in huge economic losses and reputational damage to enterprises. Utility Model Content

[0004] The purpose of this invention is to provide a flanged container for nested placement, addressing the issue raised in the background section where, during the stacking and nesting of flanged containers, it is difficult to achieve an absolutely flat and tight fit between the containers and between the cover and the container. Under the influence of external pressure, vibration, or temperature changes, tiny gaps can easily form. While these gaps may seem insignificant, they can lead to serious consequences for materials with extremely high sealing requirements. For example, in the chemical industry, many chemical raw materials are volatile, corrosive, or flammable and explosive. If the flanged container is not properly sealed, these harmful substances may leak out through the gaps, not only polluting the surrounding environment and endangering the health of operators, but also potentially causing serious safety accidents such as fires and explosions. In the food and pharmaceutical industries, poor sealing can also lead to contamination of materials by external dust, bacteria, and moisture, affecting product quality and safety, and even causing product spoilage, resulting in significant economic losses and reputational damage to enterprises.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flange barrel for nested placement, comprising a barrel body, a cover plate at the top of the barrel body, an annular top plate fixedly connected to the outer side of the bottom of the cover plate, an annular connecting plate fixedly connected to the bottom of the annular top plate, a connecting seat fixedly installed at the center of the outer side of the annular connecting plate, an annular plate movably fitted on the side of the connecting seat away from the annular connecting plate, an annular sealing gasket fixedly connected on the side of the annular plate away from the connecting seat, the side of the annular sealing gasket away from the annular plate contacting the inner wall of the barrel body, and an annular strip fixedly connected to both the top and bottom positions of the outer side of the annular top plate, a sealing strip fixedly connected to the side of the annular strip away from the annular top plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This nested flange barrel features a ring-shaped sealing gasket that maintains tight contact with the inner wall of the barrel. When the cover is closed on the barrel, the ring-shaped sealing gasket is compressed, filling the tiny gaps between the inner wall of the barrel and the ring-shaped connecting plate, forming the first reliable line of defense. This design is particularly suitable for storing chemical raw materials with volatile, corrosive, or flammable and explosive properties, effectively preventing these harmful substances from leaking into the external environment, avoiding pollution, reducing the risk of operators coming into contact with harmful substances, and thus protecting the health of operators. It also prevents serious safety accidents such as fires and explosions caused by leaks, ensuring safe production operations. The sealing strip maintains tight contact with the arc-shaped block on the inner wall of the sealing groove, forming the second sealing barrier. During the closing process of the cover, the sealing strip penetrates deep into the sealing groove and interacts with the arc-shaped block. The fully fitted blocks further prevent external air, moisture, dust, and other impurities from entering the container, while also preventing the evaporation or leakage of materials inside. This sealing structure is particularly important for the food and pharmaceutical industries, effectively preventing materials from being contaminated by external factors, ensuring product quality and safety, preventing product deterioration due to moisture, oxidation, or contamination, and reducing economic losses and reputational damage to enterprises. The positioning plate interlocks with the positioning groove, and the sealing block on the inner wall of the positioning groove is in close contact with the outer side of the positioning plate, forming a third line of defense for sealing. This design not only enhances the connection stability between the cover and the container body but also further improves the sealing performance. The sealing block can fill the tiny gaps between the positioning plate and the positioning groove, preventing materials from leaking from that area and ensuring that the materials inside the container are well-sealed and protected under various environmental conditions.
