Description

Technical Field

[0002] The three-way catalytic converter is the most important off-board purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC and NOx discharged from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. When the high-temperature automobile exhaust passes through the purification device, the purifier in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, prompting them to undergo certain oxidation-reduction chemical reactions, in which CO is oxidized into colorless, non-toxic carbon dioxide gas at high temperature; HC compounds are oxidized into water (H 2 O) and carbon dioxide; NOx is reduced to nitrogen and oxygen. The three harmful gases become harmless gases, purifying the exhaust gas of the car.

[0003] There are relatively few repair devices for three-way catalytic converters in the prior art. Most of the existing three-way catalytic converter repair devices use high-pressure water to flush the blocked part of the three-way catalytic converter. After flushing, the three-way catalytic converter is blown dry by a fan. This type of machine generally has the disadvantage of low integration, that is, when repairing the three-way catalytic converter, it is necessary to perform multiple operations in steps. After each step of the operation is completed, the three-way catalytic converter needs to be moved to the next work area for operation, which has the disadvantages of cumbersome operation and low efficiency.

[0004] A three-way catalytic cleaning and repair workbench and a repair method thereof are disclosed in the patent with publication number CN117738788A. A three-way catalytic cleaning and repair workbench and a repair method thereof, the workbench is provided with a guide column of a sliding structure, the operation driver controls the rotation of the drive screw, controls the guide column and the lifting frame to move up and down, and the lifting frame can control the limited three-way catalytic cleaner to move up and down synchronously, so as to put the three-way catalytic cleaner into the cleaning and repair pool or take it out of the cleaning and repair pool. Although a structure for conveniently moving the three-way catalytic converter is provided on the workbench, the three-way catalytic converter still needs to be frequently moved during the process of repairing the three-way catalytic converter, which has the problems of cumbersome operation and low efficiency.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example

[0030] A three-way catalytic converter integrated repair machine, such as Figure 1 As shown, it includes a body 1, a water supply mechanism, an air supply mechanism, a hot air mechanism, a waste liquid recovery mechanism 6, a cleaning gun, a high-pressure blowing gun, and a spray gun; it should be noted that the cleaning gun, the high-pressure blowing gun, and the spray gun are all existing technologies and are external devices, so the structures of these devices are not shown in the attached drawings. It should be understood that the cleaning gun, the high-pressure blowing gun, and the spray gun are all devices that can be directly purchased on the market.

[0031] The water supply mechanism, the air supply mechanism, the hot air mechanism and the waste liquid recovery mechanism 6 are all arranged in the body 1; the cleaning gun, the high-pressure blowing gun and the spray gun are arranged outside the body 1; the cleaning gun is connected to the water supply mechanism and the air supply mechanism at the same time, and the cleaning gun is used to spray out a high-pressure jet; the high-pressure blowing gun and the spray gun are connected to the air supply mechanism; the water supply mechanism and the air supply mechanism provide water and high-pressure gas to the cleaning gun, and the cleaning gun can generate dispersed high-pressure jets, which are used to flush the three-way catalytic converter 9 and flush out the blocked substances in the three-way catalytic converter 9. The spray gun is used to repair the damaged coating of the three-way catalytic converter 9. The high-pressure blowing gun is used to spray high-pressure gas to clean the three-way catalytic converter 9. The hot air mechanism can generate high-temperature gas and dry the three-way catalytic converter 9.

[0032] The body 1 is provided with a mounting tube 7 outside, and a connector 8 is provided on the top of the mounting tube 7, and the connector 8 is used to mount the three-way catalytic converter 9; the bottom of the mounting tube 7 is connected with a waste liquid pipe 22 and a hot air pipe 19; the mounting tube 7 is connected to the waste liquid recovery mechanism 6 through the waste liquid pipe 22; the mounting tube 7 is connected to the hot air mechanism through the hot air pipe 19. The mounting tube 7 is used to fix the three-way catalytic converter 9. At the same time, the waste water generated after flushing the three-way catalytic converter 9 can enter the waste liquid recovery mechanism 6 through the mounting tube 7 and the waste liquid pipe 22, so as to facilitate the recovery of heavy metals in the waste liquid and prevent the direct discharge of the waste liquid from polluting the environment.

[0033] Specifically, when in use, one end of the removed three-way catalytic converter 9 is connected to the connector 8 of the mounting tube 7, so that the three-way catalytic converter 9 is connected to the mounting tube 7. The three-way catalytic converter 9 can be blown once with a high-pressure blow gun to clean the dust on the three-way catalytic converter 9. Then the three-way catalytic converter 9 is cleaned with a cleaning gun, and the three-way catalytic converter 9 is flushed with a high-pressure jet ejected from the cleaning gun to flush the blocked parts in the three-way catalytic converter 9. Part of the waste water after flushing will flow into the waste liquid recovery mechanism 6 through the mounting tube 7 and the waste liquid pipe 22, and the waste liquid recovery mechanism 6 will precipitate the heavy metal substances in the waste liquid to prevent the waste liquid from polluting the environment. After flushing, the water stains on the three-way catalytic converter 9 can be blown dry with a high-pressure blow gun.

When repairing the three-way catalytic converter 9, the repair machine does not need to carry the three-way catalytic converter 9 according to the process, which saves time and improves efficiency. In addition, the whole machine is simple to operate, which can ensure the convenience and stability of the repair of the three-way catalytic converter 9.

This layered arrangement can effectively distinguish different functional modules and improve the operating efficiency and stability of the machine. By arranging different mechanisms in different layers, independent operation of each functional module is achieved, thereby effectively completing the cleaning, drying and waste liquid treatment of the three-way catalytic converter 9. Such a design optimizes the operating process and makes the repair machine more intelligent and efficient.
