the folded wave sintered felt consists of continuous V-shaped folding structures, connecting parts attached to the inner framework are connected between the adjacent V-shaped folding structures, and the connecting parts and the inner framework are bonded and fixed through hot melt adhesives;
the hot melt adhesive is discontinuously distributed at the bottom of the connecting part.
Furthermore, the hot melt adhesive forms two rows of discontinuous adhesive lines along the axial direction of the inner framework, and a plurality of hot melt adhesives in the two rows are arranged in a staggered mode.
Furthermore, an annular sunken clamping groove is formed in the contact surface of the fixed end portion and the folded sintered felt, and the folded sintered felt and the inner framework are connected to form a whole which is clamped in the sunken clamping groove to be fixed.
Furthermore, the outer side of the fixed end part is connected with a soft rubber ring.
After adopting the structure, the utility model has the advantages that:
1. a connecting part attached to the inner framework is arranged between the adjacent V-shaped folding structures of the folded sintered felt, and the folded sintered felt is connected with the inner framework through the connecting part, so that the contact area between the folded sintered felt and the inner framework is increased, and the fixing effect is better;
2. when connecting portion are connected with the inner frame, the hot melt adhesive divide into two and arrange, and for the discontinuous distribution of crisscross setting, both can guarantee fixed effect like this, can reduce the area of contact of hot melt adhesive and inner frame again, and the area that is blockked by the hot melt adhesive when the air current passes through reduces, guarantees the effective filtration area of folded wave sintering felt, improves filtration efficiency.
