Abstract

The invention discloses an automatic coating device of a honeycomb exhaust pipe catalyst. The automatic coating device is composed of a material storage system, a pressure control system and a rapid interface device; the material storage system is mainly composed of a storage cabin and a stirrer; the pressure control system is mainly composed of a quantitative injection pump, a discharging pipe, a one-way valve, an electromagnetic valve, a backflow pipe and a pressure-retaining cabin; and the rapid interface device is mainly composed of a rapid joint mechanism, a double-upright-post frame, a stress-applying lever system, a sealing base assembly and a cylinder. By means of application of the automatic coating device of the honeycomb exhaust pipe catalyst disclosed by the invention, constancy and homogeneity of the coating amounts of coatings are ensured; the product quality accords with enterprise standard requirements; the labour intensity of first-line operators is greatly lightened; and the production efficiency is effectively increased.

Description

technical field

[0001] The invention relates to the field of auto parts manufacturing, in particular to a catalyst automatic coating device for honeycomb exhaust pipes. Background technique

[0002] Although the fuel supply of today's gasoline engines generally adopts the multi-point EFI technology outside the cylinder, the precision of oil and gas ratio has been greatly improved, and the combustion efficiency has been gradually improved; however, due to the high speed of modern engines, it is very difficult to completely purify the exhaust gas directly in the machine. It is still a worldwide problem, and an important way to reduce emissions is through the secondary treatment of exhaust gas outside the cylinder. The three-way catalytic conversion device is one of the most mature out-of-cylinder exhaust gas treatment methods for gasoline engines at present: when the exhaust gas passes through the honeycomb pipe section in the exhaust gas pipeline, under the action of the cata...
