Adhering structure of filter layer of filter element

Abstract

The invention discloses an adhering structure of a filter layer of a filter element. The adhering structure comprises the filter element, wherein a metal net is fixedly arranged at the inner surface of the filter element; a filter paper layer is attached to the outer surface of the filter element; a joint is arranged at the filter paper connecting part of the filter paper layer; a plurality of groups of overflow holes are symmetrically formed in the joint. The adhering structure of the filter layer of the filter element has the advantages that by arranging filter paper adhering edges, an adhesive storage part, a wrinkle part, reinforcing adhering strips and the overflow holes, the contact area with the adhesive is increased by the shearing type, the adhering effect is improved, the wrinkles produced in the interior are centralized to the middle area to form the wrinkle part, the wrinkles are fixed by the reinforcing adhering strips, the filter paper and the metal net are fully attached, the gap is not reserved, and the adhering effect is improved; when the joint is adhered, one part of adhesive flows out of the overflow holes, and then is covered at the interface area of the joint;the excessive amount of adhesive in the interior is avoided; the adhering structure is suitable for different working conditions, and the better application prospect is realized.

Description

technical field [0001] The invention relates to the field of filter elements, in particular to a bonding structure of filter layers of the filter element. Background technique [0002] The filter element is a separation device for purifying the raw fluid resources and resources. Now the filter element is mainly used in oil filtration, air filtration, water filtration and other filtration industries. How to effectively stick the filter paper and metal mesh in the filter element together is the current filter element technology. Difficulties in development; the existing bonded structure of the filter element and filter layer has certain disadvantages in use. Most of the market is a bonded design with strips and seams, but the filter material itself is thicker and prone to fall off or side Generally, in order to improve the bonding effect of filter paper and metal mesh, a large amount of glue is often added to the contact surface between them to make them fully bonded.

[0002] The filter element is a separation device for purifying the raw fluid resources and resources. Now the filter element is mainly used in oil filtration, air filtration, water filtration and other filtration industries. How to effectively stick the filter paper and metal mesh in the filter element together is the current filter element technology. Difficulties in development; the existing bonded structure of the filter element and filter layer has certain disadvantages in use. Most of the market is a bonded design with strips and seams, but the filter material itself is thicker and prone to fall off or side Generally, in order to improve the bonding effect of filter paper and metal mesh, a large amount of glue is often added to the contact surface between them to make them fully bonded. Although the bonding effect is good, too much glue reduces the filtering effect of the filter element and brings There are certain adverse effects, for this reason, we propose a bonded structure of the filter element filter layer
