Description

Technical Field

[0001] The utility model relates to the technical field of high-efficiency filter accessories, in particular to a sealing device for a high-efficiency filter. Background Art

[0002] The sealing device of the high-efficiency filter is usually used in various industrial fields, such as automobile, aerospace, electronics and other industries. Its main function is to prevent dust particles, harmful gases and other pollutants from entering the system. Traditional filter sealing devices generally adopt mechanical designs, such as rotating covers, clamps and other structures. The filter is placed in the system manually or automatically, and connected to the system through threads, flanges and other methods. This kind of sealing device often finds it difficult to achieve the unity of high filtration efficiency and high reliability, and its maintenance cost is high. To solve these problems, researchers began to explore new sealing device design concepts and methods.

[0003] For example, the patent publication number CN204058457U is a high-efficiency filter compression and sealing device, which can replace the filter element and frame of the high-efficiency filter compression and sealing device through a buckle provided on the outside, which cooperates with the biosafety sealing bag. It has wide applicability in special technical fields such as biosafety, is low in cost, easy to manufacture, and easy to promote.

[0004] Although the above-mentioned device can be sealed by an external buckle, if the substance to be filtered is a gas, the gas may leak from the edge of the buckle due to its low molecular density, and the device cannot be sealed well. It is necessary to study a device for internal sealing to improve its practicality. To this end, we propose a new sealing device for high-efficiency filters. Utility Model Content
