Description

Technical Field

[0001] This utility model relates to the field of plateless high-efficiency filter technology, specifically to a filter media structure that improves the filtration efficiency and dust holding capacity of plateless high-efficiency filters. Background Technology

[0002] The outer frame of a plateless HEPA filter mainly uses aluminum alloy profiles, multi-layer plate frames, aluminum plate frames, and galvanized steel plate frames, with aluminum alloy profile frames being the most common. These are primarily manufactured in a cubic structure, and the HEPA filter structure is further divided into [specific types]. Plateless filters mainly use hot melt adhesive as the separator for the filter element, facilitating mechanized production. In addition, they have advantages such as small size, light weight, easy installation, stable efficiency, and uniform airflow. Therefore, the large-scale filters required in cleanrooms mostly adopt the plateless structure. Plated HEPA filters often use aluminum foil or paper folded into a shape as the separator for the filter element, forming air channels.

[0003] According to a patent application published on the internet (authorization announcement number: CN211585717U), "This utility model relates to the field of filter equipment technology. A detachable high-temperature resistant plateless filter includes a filter frame. Multiple screw holes are evenly distributed at the bottom of the filter frame. A filter screen is provided at the bottom opening of the filter frame. Multiple filter elements are evenly distributed inside the filter frame. A ventilation frame is provided at the top of the filter frame, and a ventilation filter screen is provided at the top of the ventilation frame. This is applicable to a detachable high-temperature resistant plateless filter. The filter frame is connected to the ventilation frame by a snap-fit ​​connection, facilitating installation and disassembly. By turning the screws, the filter elements can be fixed inside the filter frame. The number of filter elements can be increased or decreased according to the on-site working conditions to improve the filtration effect. The filter elements are easily replaced when damaged. High-temperature resistant sealing gaskets are provided around the filter screen and the ventilation filter screen to ensure the overall sealing of the filter."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] This detachable high-temperature resistant, plateless filter includes a filter frame with multiple screw holes evenly distributed at the bottom. A filter screen is installed at the bottom opening of the filter frame. The filter element can be added or removed according to the on-site working conditions to improve the filtration effect. It is easy to replace when the filter element is damaged. High-temperature resistant sealing gaskets are set around the filter screen and ventilation screen to ensure the airtightness of the entire filter. The filter element inside the filter cannot be quickly disassembled and assembled, which is inconvenient for later maintenance. Utility Model Content
