Description

Technical Field

[0001] This utility model belongs to the field of air filtration technology, specifically relating to an air filter element for a plate and frame air filter. Background Technology

[0002] The air filter element is the most crucial component of a plate-and-frame air filter. It is placed within a filter element frame to form the filtration unit of the plate-and-frame air filter. The filter element frame consists of one or more boxes with openings at the front and rear ends, arranged horizontally in multiple layers. The air filter element is placed inside the box. During operation, the sealing effect between the air filter element and its corresponding box directly affects the filtration efficiency. To avoid these issues, the filter element housing must be sealed and fixed relative to the box of the filter element frame. Patent No. 202122608798.6 discloses an air filter element and a plate-and-frame air filter containing the same element, outlining an installation structure for the air filter element relative to the filter element frame. By installing a fixing structure on the filter element frame, the air filter element can be fixed relative to the frame. This design effectively limits and locks the filter element housing within the corresponding box of the filter element frame, ensuring a reliable seal between the front panel of the filter element housing and the box of the filter element frame. However, the structure is complex and installation efficiency is low. Utility Model Content

[0003] The purpose of this invention is to provide an air filter element for a plate and frame air filter that can be installed easily while ensuring a good sealing effect.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] An air filter element for a plate and frame air filter includes a filter element housing with openings at both ends, filter material and a frame located inside the filter element housing, and a protective mesh installed at the opening ends; the filter element housing is equipped with an elastic sealing protrusion for elastically sealing relative to the filter element frame after the filter element housing is installed; the elastic sealing protrusion is arranged around the filter element housing; the elastic sealing protrusion has a hollow structure; an elastic hanger is installed on the protective mesh located at the rear end of the filter element housing, which cooperates with the elastic sealing protrusion to achieve positioning of the air filter element relative to the filter element frame.

[0006] There are multiple elastic brackets, and the outer end of each elastic bracket protrudes from the protective netting.

[0007] This utility model proposes an air filter element for a plate and frame air filter. By setting elastic sealing protrusions on the top, bottom, and side surfaces of the air filter element, and cooperating with elastic hangers, the air filter element is sealed and fixed relative to the corresponding filter element frame after installation. The structure is simple and the operation is convenient, further facilitating the installation and disassembly of the air filter element. Attached Figure Description

[0009] In the picture: 1. Filter cartridge housing, 2. Protective mesh, 3. Elastic hanger, 4. Elastic sealing protrusion. Detailed Implementation

[0010] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

[0011] like Figure 1 As shown, an air filter element for a plate and frame air filter includes a filter housing 1 with openings at both ends, filter material and a frame located inside the filter housing 1, and a protective net 2 installed at the opening ends; the protective net 2 protrudes from the filter housing 1 on all four sides; the filter housing 1 is equipped with an elastic sealing protrusion 4 for elastically sealing relative to the filter frame after the filter housing is installed; the elastic sealing protrusion 4 is arranged around the filter housing, and the elastic sealing protrusion 4 is at least flush with the protective net; the elastic sealing protrusion is a hollow structure; an elastic hanger 3 is installed on the protective net at the rear end of the filter housing, which cooperates with the elastic sealing protrusion to position the air filter element relative to the filter frame.

[0012] There are multiple elastic hanging parts 3, and the outer end of each elastic hanging part 3 protrudes from the protective net 2.

[0013] When the air filter element is pushed into the filter element frame, the elastic sealing protrusion deforms. After the rear end face of the air filter element, the protective net 2, contacts the rear wall of the filter element frame, the air filter element is installed in place. The elastic sealing protrusion returns to its original position and elastically tightens in the cavity between the filter element housing and the filter element frame. The elastic hanger hooks onto the filter element frame through elastic deformation to achieve positioning.
