Problems solved by technology

This traditional form of assembly cannot ensure the firmness of the carrier in the radial direction, and the stability between layers cannot be guaranteed. When passing through the bumps and vibrations of the vehicle during driving, the carrier will be out of shape due to the vibration, making the air permeability of the carrier Reduced performance and catalytic efficiency and consequently reduced stability

Example Embodiment

[0031] The core of the present invention is to disclose a metal fiber carrier fastener, which makes the metal fiber carrier layer and the layer tightly connected, and will not deform the carrier due to the vibration during driving or the internal pressure of the carrier itself. The original catalytic purification effect.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] See figure 1 with figure 2 , figure 1 with figure 2 It is a schematic structural diagram of a metal fiber car...

Abstract

The invention discloses a tail gas purifier and a metal fiber carrier fastening element and a fastening method thereof. The metal fiber carrier fastening element for fastening a metal fiber carrier made of metal fiber screen mesh in a coiling way; the metal fiber carrier fastening element comprises a fastening part and a locking part which are fixedly connected into an integral structure; the fastening part is provided with a dual-screw structure matched with meshes in the metal fiber screen mesh; and the size of the locking part is greater than that of the meshes. According to the technical scheme, a unique dual-screw structure is adopted for fixing, adverse effects generated by the fracture of metal screen meshes are prevented completely, and the possibility of metal fiber carrier layering is eradicated radically, thus the metal fiber carrier is homogeneous and complete, meanwhile, the catalytic and purification efficiency of the metal fiber carrier is intensified greatly, the through performance of the metal fiber carrier is ensured, and the purification capability of the metal fiber carrier is improved.

Description

technical field [0001] The invention relates to the technical field of metal fiber carriers, in particular to a fastener for an exhaust gas purifier and a metal fiber carrier and a fastening method thereof. Background technique [0002] At present, there are mainly three types of carrier materials used in automobile exhaust purifiers: ceramic particle carrier materials, honeycomb ceramic carrier materials and metal carrier materials. The disadvantages of ceramic granular carrier materials are: low strength, easy to break, and high resistance, which affect the dynamic performance of automobile engines. The honeycomb ceramic carrier has a large heat capacity, slow heating, low thermal conductivity, and relatively low mechanical strength, which limits the purification efficiency of the catalytic converter. Metal carrier materials have good thermal stability, high mechanical strength, large specific surface area, and small heat capacity, but the preparation process of honeycomb...
