Embodiment Construction

[0045] figure 1 A cylindrical filter element 1 is shown, the filter element body 3 of which is formed by a support body 5 and structures 6 , 7 . In the case of the filter element 1 , corresponding coaxial and concentrically positioned hollow cylindrical structures 6 , 7 are arranged on the inner region 14 and the outer region 13 of the support body 5 . Here, a flow 8 of fluid through the filter element 1 takes place, for example from the outside of the hollow-cylindrical filter element 1 into the inner region of the hollow-cylindrical filter element 1 , whereby the fluid is then guided further substantially parallel to the central axis 2 . Of course, instead of the hollow cylindrical filter element 1 , any desired geometry of the filter element 1 with the structure 6 and the support 5 can be used. Here, flat and / or cuboidal filter elements 1 are preferably used.

[0046] The outer structure 6 is built as a three-dimensionally interconnected lattice structure 15 and is produc...

Abstract

The present invention relates to a filter element (1) for a filter unit (30) for filtering a fluid, wherein the filter element (1), so as to be permeable to the fluid, consists of at least one structural body (6, 7) and a support body (5) and has a large number of apertures/pores (17). The structural boy (6, 7) and the support body (5) are each produced by means of a 3D printing process, wherein the structural body (6, 7) has a repeating three-dimensionally crosslinked lattice structure (15) and the support body (5) has a cell structure (10). The apertures/pores (17) of the lattice structure (15) are formed by inter-crosslinked and rigidly connected rod elements (16). The problem addressed by the filter element (1) is that of providing a new optimal and robust filter structure having a good filtering effect and a good deep loading capacity using a 3D printing process. The present invention is used to filter fluids in technical modular units/machine units or motors.

Description

technical field [0001] The invention relates to a filter element for a filter unit for filtering fluids. Background technique [0002] A filter element is used in a corresponding filter unit for filtering solid particles out of a liquid, which filter element has a filter body with a filter material for particle filtration. These filter materials have a filter structure made of suitable materials. For example, filter structures made of woven fabrics and / or cellulosic materials are used which, due to the material, have limited filter performance and can only be made into complex shapes to a limited extent. Filter elements of this type have predetermined and unchangeable filter properties, which only allow optimization of the fluid to be filtered to a limited extent. [0003] A filter material for adsorption filtration is known from DE 43 44 805 C2, which has a filter structure composed of particles, which is formed by a fibrous three-dimensional framework of composite fibers...
