Abstract

The invention discloses a hole plugging device and process for a honeycomb ceramic carrier for tail gas purification of a thin-wall diesel engine, and belongs to the technical field of honeycomb ceramic carrier production. The hole plugging device for the honeycomb ceramic carrier for tail gas purification of the thin-wall diesel engine comprises a base, a box body and four sliding columns. The bottom wall of a lifting plate is connected with a pressing mold, the top walls of every two corresponding adjacent sliding columns are connected with a connecting block, the top wall of a connecting plate is connected with a power assembly, the bottom wall of the lifting plate is connected with a limiting assembly, and the top wall of the base is connected with a scraping assembly. The limiting assembly and the scraping assembly are both matched with the power assembly. The power assembly comprises a rotating motor, an adjusting assembly and a rotating rod, wherein the rotating motor is connected to the top wall of the connecting plate, one end of the rotating rod is connected to the output end of the adjusting assembly, and the other end of the rotating rod is rotationally connected to the top wall of the lifting plate. According to the hole plugging device and process for the honeycomb ceramic carrier for tail gas purification of the thin-wall diesel engine, hole plugging can be conveniently carried out on holes with different depths of ceramic carriers, the ceramic carriers can be prevented from deviating during hole plugging, and the situation that a pressing face is not flat can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of honeycomb ceramic carrier production, in particular to a hole-plugging device and a hole-plugging process of a honeycomb ceramic carrier for purifying exhaust gas of a thin-walled diesel engine. Background technique [0002] The honeycomb ceramic carrier in the diesel particulate filter can filter the soot particles in the diesel exhaust emission, and the filtering efficiency can reach more than 90%. The structure of the honeycomb ceramic carrier includes inlet channels, outlet channels and porous partition walls, and the channels need to be cross-blocked. When the exhaust gas flow enters from one end of the honeycomb ceramic and flows out from the other end, the gas can be forced to pass through the wall, so as to achieve the purpose of filtering soot particles. [0003] The production process of the honeycomb ceramic carrier is to leave a machining allowance in the diameter direction, and after grindin...
