[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] Reference below Figures 1 to 7An environmentally friendly filter according to an embodiment of the utility model is described, including a metal filter body 1, a positioning strip 2 and a frame 3, the metal filter body 1 is located between the positioning strip 2 and the frame 3, the positioning strip 2, the metal filter body 1 and the frame 3 are welded together, and the welding joint between the positioning strip 2 and the frame 3 passes through the metal filter body 1, and the surface of the metal filter body 1 is provided with a folded portion.

[0025] In this structure, the metal filter body 1 is clamped between the positioning strip 2 and the frame 3 to fix the position of the metal filter body 1, and the surface of the metal filter body 1 is provided with a folded portion to increase the filtering area and facilitate cleaning. The metal filter body 1 has the characteristics of large flow filtration, high temperature resistance, high strength and long life.

[0026] The metal filter body 1 described in this structure is a metal fiber felt or a metal fiber mesh. Metal fiber felt, also known as metal fiber sintered felt, refers to a felt material made of metal fibers with a diameter of microns and sintered at high temperature. Metal fiber felt has the advantages of high strength, light weight, long service life, high temperature resistance, high filtration accuracy, and corrosion resistance. Metal fiber felt is usually made of metal fiber as a substrate, and its production process includes raw material selection, metal fiber preparation, stacking, laying, sintering, etc. Metal fiber preparation is a key link in the production of metal fiber felt, and plays a decisive role in its performance and quality. The main preparation methods of metal fibers include the hanging drop melt traction method and the melt spinning method. The hanging drop melt traction method refers to placing a metal wire in a heater, and making it through processes such as melting, droplets, cooling, and throwing.

[0027] Metal fiber mesh refers to a fiber-shaped material with a high metal content, continuous distribution of metal materials, and a lateral size of micrometers.
