Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a composite repeatedly folded wire-wound filter element. Background Art

[0002] The wire-wound filter element is a deep filter element used for filtering low viscosity and low impurity content. It is made of textile fiber lines (polypropylene lines, absorbent cotton lines, etc.) with good filtering performance, which are precisely wound on a porous skeleton (polypropylene or stainless steel) according to a specific process. It has a honeycomb structure that is sparse on the outside and dense on the inside. It can effectively remove suspended matter, particles, rust and other impurities in the fluid, and has very good filtering characteristics and adsorption. The current filter core structure has poor strength and poor pressure resistance, and is prone to deformation, which will affect the normal flow of the liquid inside the core. Therefore, we propose a composite repeated folded wire-wound filter element. Utility Model Content

[0003] The utility model aims to provide a composite repeatedly folded wire-wound filter element to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a composite repeatedly folded winding filter element, comprising a tube core, the outer wall of the tube core is provided with a winding layer, the inner wall of the tube core is provided with a reinforcement component, the reinforcement component comprises five groups of reinforcement frames provided on the inner wall of the tube core, and the outer wall of the reinforcement frame is provided with six groups of reinforcement ribs.

[0005] Furthermore, the five groups of reinforcement frames are distributed in a linear array from top to bottom in the tube core.

[0006] Furthermore, the reinforcement frame is arranged in an equilateral triangle shape.

[0007] Furthermore, the six groups of reinforcing ribs are distributed in a circular array on the outer side wall of the reinforcing frame.

[0008] Furthermore, limiting plates are sleeved and installed on both upper and lower sides of the outer wall of the tube core, and the opposite side walls of the two groups of limiting plates are respectively connected to the upper and lower side walls of the winding layer.

[0009] Compared with the prior art, the utility model has the beneficial effect that the utility model can improve the strength inside the tube core under the action of the reinforcing component, so that the tube core will not be deformed when squeezed from the outside, and the normal flow of the liquid inside the tube core is guaranteed.
