A two-carrier automotive three-way catalytic converter

Abstract

The invention discloses a double-carrier automobile three-way catalytic converter. The double-carrier automobile three-way catalytic converter is characterized by structurally comprising rotating sealing rods, a square connecting block, a connecting tube, a duster-removing and sealing device and a fixed frame, wherein the rotating sealing rods are separately arranged above left and right ends of the duster-moving and sealing device, and are in clearance fit; and the two rotating sealing rods are positioned on the same plane. The dust-removing and sealing devices are arranged, so that when a car travels, discharged waste gas is filtered by a filter plate, and filtered dust adsorbed onto the filter plate can be cleared, and therefore, a condition that filtration of the catalytic converter isincomplete as the filter plate adsorbs much dust is avoided, and environmental pollution is reduced; and a rotating pushing device is arranged inside the device, so that a catalytic converter pipeline can be sealed while the car breaks down, and therefore, animals with relatively small figures are prevented from entering the catalytic converter to bite parts inside the catalytic converter to cause faults of the catalytic converter, and the service life is relatively long.

Description

technical field [0001] The invention relates to a two-carrier three-way catalytic converter for automobiles, belonging to the field of three-way catalytic converters. Background technique [0002] The device can be installed on the car, through which the exhaust gas emitted by the car can be filtered and catalyzed, and the dust formed after filtering and catalyzed can be cleaned and discharged, and the pipeline of the catalytic converter can also be closed when the engine is turned off. [0003] when prior art is in use; [0004] 1. When the car is driving, the exhaust gas needs to be filtered through the catalytic converter and then discharged into the air. During the filtration, it is easy to absorb the dust attached to the exhaust gas in the filter plate. After a long time of use, it will be harmful The exhaust gas is not filtered thoroughly, so that the exhaust gas is discharged into the air and pollutes the surrounding air; [0005] 2. When the car is turned off, the ...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a dual-carrier three-way catalytic converter for automobiles to solve the problem when the prior art is in use; when the automobile is driving, the exhaust gas needs to be filtered through the catalytic converter, and then It is discharged in the air, and in the filtration, it is easy to absorb the dust attached to the exhaust gas in the filter plate. After a long time of use, the exhaust gas is not filtered thoroughly, so that the exhaust gas is discharged in the air and pollutes the surrounding air; When the car is turned off, the pipeline of the catalytic converter is unobstructed, and small animals can run into the catalytic converter, thereby biting the parts installed inside the catalytic converter, causing the catalytic converter to malfunction or be destroyed. shorter question
