Description

Technical Field

[0001] The utility model belongs to the technical field of filtration, and in particular relates to a combined filter element. Background Art

[0002] The filter is a common conventional equipment used for air purification and water filtration, and the filter element is the most core component of the filter. The filter element is usually installed by fixing it on the filter element bracket. It can be installed in a flat or cylindrical shape. Conventional filter elements are mostly single-layer non-woven fabrics or single-layer filter paper. Although they can meet the general usage requirements, they not only have limited filtering effects, but are also easily damaged during the winding operation, and it is difficult to ensure an effective shape, so their applicability and practicality are limited. Summary of the Invention

[0003] The purpose of the utility model is to provide a combined filter element which has a reasonable structure and is conducive to improving the filtering effectiveness.

[0004] The technical solution for achieving the purpose of the utility model is a combined filter element, comprising a honeycomb filter base layer and a honeycomb filter surface layer;

[0005] The honeycomb filter surface layer is stacked on the surface of the honeycomb filter base layer in a wave shape, and the wave troughs are fixedly connected to the surface of the honeycomb filter base layer by hot melting at equal intervals.

[0006] It is further preferred that the honeycomb filter base layer and the honeycomb filter surface layer are both made of PP material structures.

[0007] More preferably, the maximum distance between the honeycomb filter surface layer and the honeycomb filter base layer is 1-3 cm.

[0008] More preferably, the thickness of the honeycomb filter base layer and the honeycomb filter surface layer are both 0.1-0.5 cm.

[0009] The utility model has positive effects: the structure of the utility model is reasonably set up. By arranging the honeycomb filter layer in a wave shape on the honeycomb filter base layer, it is not only beneficial to improve the effectiveness and reliability of filtration, but also the overall structure has good softness, which is convenient to fold or wind into a cylindrical shape for use, thereby improving the convenience of use, and is not easy to be damaged, which is beneficial to improving the service life, and has strong applicability and good practicality.

Example

[0016] See Figures 1 to 3 As shown, a combined filter element includes a honeycomb filter base layer 1 and a honeycomb filter surface layer 2; in this embodiment, the honeycomb filter base layer and the honeycomb filter surface layer are both PP material structures. Moreover, during processing, the honeycomb filter surface layer is stacked in a wavy shape on the surface of the honeycomb filter base layer, and the troughs are equidistantly spaced and hot-melt-connected and fixed to the surface of the honeycomb filter base layer. Through the above structure, the stability and reliability of the connection between the two can be improved. At the same time, the maximum distance between the honeycomb filter surface layer and the honeycomb filter base layer is 1-3 cm. The thickness of the honeycomb filter base layer and the honeycomb filter surface layer are both 0.1-0.5 cm. The wavy honeycomb filter surface layer is conducive to increasing the filtration area, and at the same time, in conjunction with the honeycomb filter base layer, secondary filtration is achieved, thereby improving the filtration effectiveness. In addition, the use of the PP material structure is conducive to improving processing efficiency, reducing processing costs, increasing service life, and having strong practicality.

[0017] The utility model has positive effects: the structure of the utility model is reasonably set up. By arranging the honeycomb filter layer in a wave shape on the honeycomb filter base layer, it is not only beneficial to improve the effectiveness and reliability of filtration, but also the overall structure has good softness, which is convenient to fold or wind into a cylindrical shape for use, thereby improving the convenience of use, and is not easy to be damaged, which is beneficial to improving the service life, and has strong applicability and good practicality.

[0018] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.
