Embodiment Construction

[0080] Next, embodiments of the present invention will be described in detail with reference to the drawings.

[0081] Such as Figure 1 to Figure 5 As shown, the metal filter 1 of the present invention is provided on one or both of the above-mentioned peaks 20 and valleys 21 of the metal plate main body 2 having a plurality of columns of peaks 20 and valleys 21 alternately formed for Through grooves 10 extending in the row direction through which fluid passes, and opening edge portions 11 of the through grooves 10 are provided with rising pieces 30 and 31 rising toward the convex side of the peaks 20 or valleys 21 .

[0082] Although not shown in the figure, the metal filter 1 can be formed as a cleaning filter having catalyst layers such as photocatalysts, activated carbon, aromatics, manganese dioxide, etc., and adsorption layers on the surface, or without forming such catalyst layers, And it is preferable to directly use the metal material as a grease filter in the kitche...

Abstract

The invention provides a metal filter. Either or both of a peak and a trough of a metal plate body (2) of peaks (20) and troughs (21) in multiple lines is or are formed in an alternating manner. The metal filter is provided with a communicating groove (10) enabling fluids to extend along a line direction. Additionally, an opening edge part (11) of the communicating groove is equipped with verticalpieces (30, 31) laterally vertical to convex surfaces of a peak (20) and a trough (21). For instance, the vertical pieces (30, 31) are respectively arranged on both sides of a pair of opening edge parts which extend along a line direction by being opposite to each other. The vertical pieces are long pieces which roughly extend at all opening edge parts. Accordingly, contact areas between fluids such as air and the like, and a catalyst layer and an absorption layer are ensured at low cost. Furthermore, passing resistance of fluids is inhibited so that passing efficiency is increased. As a result, excellent purification effect can be efficiently obtained.

Description

technical field [0001] The present invention relates to a metal filter suitable for use as a cleaning filter for fluids and a grease filter for kitchens, etc., having a catalyst layer such as photocatalyst, activated carbon, aromatic agent, manganese dioxide, etc., and an adsorption layer formed on the surface. Background technique [0002] As such a filter, for example, a photocatalyst filter is a filter that decomposes and removes harmful substances in the air by using a photocatalyst excited by ultraviolet rays when the air passes through the photocatalyst layer. , a structure in which a photocatalyst layer carrying titanium oxide or the like is formed on the surface of a plate-shaped substrate such as a metal mesh or a metal mesh is proposed. However, a filter based on a metal mesh or a metal mesh cannot sufficiently secure an area where passing air contacts the photocatalyst layer, and there is a problem that a sufficient cleaning effect cannot be obtained with only one...
