Description

Technical Field

[0001] The present invention relates to the technical field of air filtration, and in particular to a partitioned air filtration unit and a production line thereof. Background Art

[0002] Air filter refers to air filtering device, which is generally used in clean workshops, clean factories, laboratories and clean rooms, or for dust prevention of electronic machinery and communication equipment. Air filters are divided into bag air filters, plate air filters and box air filters according to their composition and structure. Box air filters are more suitable for use in harsh environments than bag air filters and plate air filters under the same filter material.

[0003] In the existing box-type air filters, corrugated paper (i.e., corrugated filter paper) plus partitions are mostly used to increase the filtering area and ensure the smooth flow of gas. For example, the publication number CN208865353U discloses a high-efficiency multi-layer partition-type air filter that is easy to clean, including a mounting frame and a filter element assembly. The mounting frame is composed of a group of U-shaped frames and a group of mounting side plates. The filter element assembly includes a partition plate and filter paper. The upper and lower ends of the partition plate are symmetrically provided with assembly sleeves, and spacer sleeves are padded between two adjacent groups of assembly sleeves. Multiple groups of assembly sleeves and spacer sleeves are interspersed and connected in series through threaded rods. The left and right ends of the threaded rod respectively penetrate the left side wall and the mounting side plate of the U-shaped frame. The left end of the threaded rod is provided with a fixed end, and the right end of the threaded rod is provided with a locking nut. The left side wall and the mounting side plate of the U-shaped frame are provided with mounting countersunk holes, and the fixed end and the locking nut are respectively located in the mounting countersunk holes. Although the patent technology can reduce the deformation of corrugated paper through the partition, the partition will occupy a lot of space, and this structure can generally only be used for upper and lower ventilation structures. A small part adopts a partition-free structure, such as the patent publication number CN103382909A, which discloses a corrugated air filter, including a plurality of filter papers, an upper plastic fixing and a lower plastic fixing, the middle of the upper plastic fixing and the lower plastic fixing are respectively provided with through holes, the upper plastic fixing and the lower plastic fixing are arranged in parallel and spaced apart, the heights of the plurality of filter papers are equal, the filter papers are arranged between the upper plastic fixing and the lower plastic fixing, the height direction of the filter papers is perpendicular to the plane where the upper plastic fixing and the lower plastic fixing are located, the filter papers are arranged at intervals along the periphery of the through hole, the inner side of any filter paper is connected to the periphery of the through hole, and the width of any filter paper is greater than or less than the width of its adjacent filter paper. A plurality of slots are provided in the lower plastic fixing, and the lower end of any filter paper is respectively inserted into one of the slots. This patented technology adopts a slot structure in the structure to place the corrugated paper in the corresponding slot structure. The removal of the partition increases the occupied area of ​​the filter paper to a certain extent, but the spacing between the slots will result in a limited increase in the filter paper area. In addition, since there is no partition, the deformation of the corrugated paper will cause the smooth flow of gas to be blocked, affecting the filtering effect. At the same time, it will also make the installation more cumbersome, and the corrugated paper needs to be inserted into the slot structure one by one. Summary of the invention
