Description

Technical Field

[0001] The utility model relates to the technical field of gas cabinet sealing, in particular to a sealing structure of a hydrogen purifier door. Background Art

[0002] A hydrogen purifier is a device used to remove impurities from hydrogen and improve its purity. It is widely used in many industries, such as chemical industry, electronics, metallurgy, scientific research and other fields. As the requirements for hydrogen purifiers become increasingly stringent, a gas cabinet is usually installed on the outside of the hydrogen purifier, which not only plays a buffering role, but also ensures the pressure stability of hydrogen during transportation and use. However, since the gas cabinet is under positive pressure for a long time, the single-layer sealing strip between the door panel and the cabinet body cannot provide sufficient sealing effect, resulting in seal failure and even potential safety hazards. Therefore, a sealing structure for the door body of a hydrogen purifier is proposed to solve the above-mentioned problems. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a sealing structure for a hydrogen purifier door body, comprising a door body of a hydrogen purifier, wherein a door panel adapted to the door body is provided at the opening of the door body, a bending portion is provided at one end of the door panel close to the inner wall surface of the door body, a crossbeam pressing edge is provided on the inner wall surface of the door body, an inner sealing strip is provided on the surface of the crossbeam pressing edge, wherein the inner sealing strip is located between the crossbeam pressing edge and the bending portion to form a seal between the door body and the door panel, a card-strip type outer sealing strip is provided on the side surface of the door panel close to the door opening, wherein the end of the crossbeam pressing edge can contact the card-strip type outer sealing strip, and the door panel is close to the door body to form a double seal between the door body and the door panel through the inner sealing strip and the card-strip type outer sealing strip.

[0004] Furthermore, the bending portion and the door panel are integrally bent and formed, and the cross section thereof is L-shaped.

[0005] The beneficial effects of the present invention are as follows: the present invention arranges a crossbeam pressure edge, arranges an inner sealing strip on its inner wall surface, and forms a first seal with the bent portion of the door panel, and at the same time arranges a card-type outer sealing strip on the outer side of the door panel, which contacts the end of the crossbeam pressure edge to form a second seal. The double sealing design greatly enhances the sealing effect between the door body and the door panel, effectively prevents gas leakage in the gas cabinet, and ensures the safety and operation efficiency of the hydrogen purifier. At the same time, the bent portion and the door panel are arranged with an integrated bending molding, which not only simplifies the manufacturing process, but also improves the integrity and stability of the structure.

[0009] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0010] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0011] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0012] In the embodiment, Figure 1-2A sealing structure of a hydrogen purifier door body is provided, comprising a door body 1 of the hydrogen purifier, wherein a door panel 2 adapted to the door body 1 is provided at the opening of the door body 1, a bending portion 3 is provided at one end of the door panel 2 close to the inner wall surface of the door body 1, a crossbeam pressing edge 4 is provided on the inner wall surface of the door body 1, an inner sealing strip 5 is provided on the surface of the crossbeam pressing edge 4, wherein the inner sealing strip 5 is located between the crossbeam pressing edge 4 and the bending portion 3 to form a seal between the door body 1 and the door panel 2, a card-type outer sealing strip 6 is provided on the surface of one side of the door panel 2 close to the opening of the door body 1, wherein the end of the crossbeam pressing edge 4 can contact the card-type outer sealing strip 6, and the door panel 2 is close to the door body 1 through the inner sealing strip 5 and the card-type outer sealing strip 6. It forms a double seal between the door body 1 and the door panel 2. The door panel 2 is adapted to the opening of the door body 1 to ensure that they can fit tightly in the closed state. When the door panel 2 is closed and pressed, the bent portion 3 will closely contact and compress the inner sealing strip 5 and deform to form a first layer of seal to prevent external air from entering. At the same time, the end of the crossbeam pressure edge 4 will contact and exert a certain pressure with the card-strip type outer sealing strip 6 to form a second layer of seal. The card-strip type outer sealing strip 6 not only increases the reliability of the seal, but also through its special card-strip design, ensures that it can maintain good sealing performance after multiple opening and closing operations. Under the action of double sealing, the internal air pressure can be maintained to the greatest extent, ensuring the safety and operation efficiency of the hydrogen purifier.
