Problems solved by technology

When this kind of filter paper is wound into a filter element, the wavy structure is usually collapsed. The mechanical strength of the filter paper is not good, which leads to a decrease in the filtration efficiency of the filter element. At the same time, the crease line is easy to wrinkle. Curved sideways, causing difficulty in winding

Embodiment Construction

[0015] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 , figure 2 As shown, the filter paper structure includes a flat filter paper 1 with a flat structure and a wavy filter paper 2 with a wavy structure. The wavy filter paper 2 is pasted on the flat filter paper 1 by hot glue 3, and heated The glue line width of Sol 3 is 0.6-0.8mm.

[0017] The manufacturing method of the filter paper structure includes the following steps: applying pressure to a filter paper through a corrugating roller assembly to form a wave-shaped filter paper 2; and then bonding the wave-shaped filter paper 2 and the plate-shaped filter paper 1 together by hot-melt adhesive. Wherein, the temperature of the corrugation roller assembly is 40-60° C., and the rotat...

Abstract

The invention discloses a filter paper structure which comprises structurally plate-shaped filter paper and structurally wavy filter paper. The wavy filter paper is adhered on the plate-shaped filter paper by hot-melt adhesive. The invention further discloses a method for manufacturing the filter paper structure. The method includes steps of applying pressures on filter paper by the aid of a wave press roll assembly to form the wavy filter paper; adhering the wavy filter paper with the plate-shaped filter paper by the hot-melt adhesive. The filter paper structure and the method have the advantages that wavy structures can be prevented from being collapsed when the filter paper is wound to form a filter element, the filter paper is high in mechanical strength and firm in structure, and accordingly the quality of products can be guaranteed.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter paper structure and a manufacturing method thereof. Background technique [0002] In the production process of the coarse-effect filter element, the filter paper is usually made of coarse-effect wrinkle filter paper, which is first uncoiled, and then folded, with a single side of 10mm at 180 degrees, and after crimping, then corrugated. treatment, and finally heat the sol and wind it into a filter element. When this kind of filter paper is wound into a filter element, the wavy structure is usually collapsed. The mechanical strength of the filter paper is not good, which leads to a decrease in the filtration efficiency of the filter element. At the same time, the crease line is easy to wrinkle. Curved sideways, making winding difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a filter paper structure, which has bet...
