Three-dimensional reticular porous titanium fiber sintered felt

Abstract

The utility model belongs to the technical field of sintered felts, and particularly relates to a three-dimensional net-shaped porous titanium fiber sintered felt which comprises a titanium fiber sintered felt body, and the titanium fiber sintered felt body is formed by sintering a first supporting layer, a first titanium fiber filtering layer, a second supporting layer, a second titanium fiber filtering layer and a third supporting layer. A second stable protruding block is fixed to the second supporting layer, and the two ends of the second stable protruding block extend out of the second supporting layer. Third stable protruding blocks are evenly fixed to the third supporting layer. The multi-layer titanium fiber sintered felt structure is arranged, and the pore diameter of the titanium fiber sintered felt is sequentially reduced from top to bottom, so that multi-stage filtration can be realized, and the filtration efficiency and the assimilative capacity are better; after sintering, the first stable convex blocks are embedded into the second filter holes, the second stable convex blocks are embedded into the second filter holes and the fourth filter holes, the third stable convex blocks are embedded into the fourth filter holes, and the upper filter screen and the lower filter screen are matched, so that the structural strength and the stability of the sintered felt are greatly improved, and the service life of the sintered felt is prolonged.
