Description

Technical Field

[0001] The invention relates to the technical field of automobile parts cleaning, in particular to a cleaning device for a three-way catalytic converter of an engine without disassembly. Background Art

[0002] The three-way catalytic converter is an external purification device installed in the automobile exhaust system. Its main function is to convert harmful gases emitted by automobile exhaust, such as carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx), into harmless carbon dioxide, water and nitrogen through oxidation and reduction.

[0003] German cars (such as Mercedes-Benz, BMW, Audi and other brands) are designed and tuned for high power and high performance, which results in high cylinder pressure and cylinder temperature when the engine is working at high power, high requirements for combustion control accuracy and fuel cleanliness, and more prone to carbon deposits. Traditional cleaning methods for auto parts rely on manual disassembly followed by chemical immersion or high-pressure water gun washing, which is not only time-consuming and labor-intensive but also may cause damage to the parts themselves, and also increases the cost burden of car owners. New cleaning methods for three-way catalytic converters mostly use dedicated cleaning devices to clean the parts.

[0004] However, when cleaning the three-way catalytic converter, the existing cleaning device for the three-way catalytic converter generally sprays out a fine mist through the connecting pipe to cover the entire inside of the three-way catalytic converter to complete the cleaning of the three-way catalytic converter. The inner wall of the connecting pipe between the water pump and the solution tank will gradually form a thicker scale layer due to the adhesion of the heated cleaning liquid. The pipe is located in the device and is difficult to observe. If the scale layer is not cleaned, it will take a long time for the nozzle to spray out the fine mist. Within the set time, the fine mist may not be able to completely fill the inside of the three-way catalytic converter, resulting in incomplete cleaning of the three-way catalytic converter, affecting the cleaning effect of the cleaning device.

The pressure water pump 6 extracts the solution through the water pump connecting pipe 9, and after pressurization, it is transported to the porous nozzle 7 through the water pipe 5. The solution is sprayed through the porous nozzle 7 so that the fine mist of the solution fills the inside of the three-way catalytic converter, and the cleaning of the inside of the three-way catalytic converter is completed.

After the solution is heated, a pressurized water pump 6 is started by the controller 3. The pressurized water pump 6 extracts the solution through a water pump connecting pipe 9, and after pressurization, the solution is transported to a porous nozzle 7 through a water pipe 5. The solution is sprayed through the porous nozzle 7 so that the fine mist of the solution fills the interior of the three-way catalytic converter, and the interior of the three-way catalytic converter is cleaned. After cleaning, the sewage inside the three-way catalytic converter is extracted by an exhaust fan, and the cycle is repeated several times until the color of the extracted sewage is close to the color of the solution, thereby completing the cleaning of the interior of the three-way catalytic converter and avoiding damage to the delicate structure inside the three-way catalytic converter. During cleaning, a scale layer will adhere to the inner wall of the first connecting pipe 207. When the pressurized water pump 6 pumps water out, the water flows through the liquid outlet 10, which drives the rotating blade 202 to rotate. Through the first connecting frame 204, the first rotating rod 206 can only rotate, thereby driving the second connecting frame 205 and the first gear ring 203 to rotate, thereby driving the first gear 201 to rotate, so that the second rotating rod 209 rotates, driving the third rotating rod 210 to rotate, so that the second gear 211 at the bottom of the second rotating rod 209 drives the driven gear ring 208 to rotate, so that the driven gear ring 208 drives the remaining three second gears 211 to rotate, thereby driving the remaining three third rotating rods 210 to rotate, so that the four second bevel gears 212 drive the four first bevel gears 213 to rotate synchronously, so that the first bevel gear 213 drives the fourth rotating rod 214 to rotate, and through the limiting of the first support plate 215, the cam 21 9 is rotated, and then through the limit of the connecting frame 217, the driven rod 220 and the T-shaped moving plate 218 are driven to perform horizontal reciprocating motion, so that the T-shaped moving plate 218 drives the spring 222 and the impact rubber plate 223 to hammer the first connecting pipe 207. When the spring 222 and the impact rubber plate 223 hammer the first connecting pipe 207, the first rotating rod 206 drives the circular plate 224 to rotate, so that the circular plate 224 drives the brush rod 225 to rotate, and the inner wall of the first connecting pipe 207 is cleaned. At the same time, the outer wall of the first connecting pipe 207 is hammered, so that the scale layer on the inner wall of the first connecting pipe 207 is more difficult to adhere, and the inner wall of the connecting pipeline of the pressurized water pump 6 and the washing box 1 will not gradually form a thicker scale layer due to the attachment of the heated cleaning liquid, and the time for the nozzle to spray out the fine mist will not be long due to the scale layer.
