Winding fixing method for preventing fold deformation of filter element, filter element and filter

Abstract

The invention discloses a winding fixing method for preventing fold deformation of a filter element. The method comprises the following steps: (1) selecting a folded cylindrical filter element, wherein the folded cylindrical filter element comprises a plurality of continuous folded portions, and the folded portions are interconnected with one another to form a cylindrical structure; selecting glass fibers or cotton threads; selecting glue; and (2) winding the glass fibers or the cotton threads at an outer side surface of the folded cylindrical filter element, and gluing the wound glass fibers or cotton threads while the glass fibers or the cotton threads are spirally wound; and after the glue is dried, fixedly binding the glass fibers or the cotton threads and filter paper by virtue of the glue. The invention also discloses a filter element adopting the method to prevent the fold deformation of the filter element. The invention also discloses a filter adopting the filter element to prevent the fold deformation of the filter element. The fold deformation phenomenon of the filter element can be effectively avoided, a filter area of the filter element or the service life of the filter element can be ensured, an effect of an outer protective net can be replaced, raw materials are effectively saved, and an energy-saving and environmental protection effect can be achieved.

Description

technical field [0001] The invention relates to filter element manufacturing technology, in particular to a winding fixing method for preventing filter elements from collapsing and deforming, a filter element and a filter. Background technique [0002] Conventional filter elements have inner and outer guards. The inner protection net mainly plays the role of increasing the compressive strength and strengthening the support, while the net protection net mainly plays the role of protecting the filter material. Most of the air filter elements and oil filter elements are externally pressured, that is, the air or oil flows from the outside to the inside. In real life, it often happens that due to the action of external force and resistance, the filter paper or filter material is seriously folded or deformed, which greatly affects the effective use of the filter area and the service life of the filter element, making the filter quality of the filter element poor. Stable, short l...

Problems solved by technology

In real life, it often happens that due to the action of external force and resistance, the filter paper or filter material is seriously folded or deformed, which greatly affects the effective use of the filter area and the service life of the filter element, making the filter quality of the filter element poor. stable, short lifespan

Therefore, there are still many unreasonable places in the traditional filter element, which need to be improved and perfected.
