Description

Technical Field

[0001] This utility model relates to the field of three-way catalytic converter cleaning technology, specifically to a high-efficiency automotive three-way catalytic converter cleaning device. Background Technology

[0002] The three-way catalytic converter is a core purification device installed in the vehicle's exhaust system. Its main function is to convert three harmful gases in the vehicle's exhaust gas—carbon monoxide, hydrocarbons, and nitrogen oxides—into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. A three-way catalytic converter cleaning device is used to clean impurities such as carbon deposits and sulfur and phosphorus compounds inside the three-way catalytic converter. For example, a three-way catalytic converter cleaning device with announcement number CN222830236U can clean multiple three-way catalytic converters simultaneously, improving cleaning efficiency. The device can fix three-way catalytic converters of different sizes through a separator component to avoid friction between the catalytic converters.

[0003] While the aforementioned technology can clean multiple automotive catalytic converters simultaneously, it suffers from poor internal cleaning of the catalytic converters. This technology involves immersing the catalytic converter in a cleaning solution, but the cleaning process primarily targets the internal components. Key contaminants mainly adhere to the inner walls of the microporous channels within the catalytic converter. If the internal components are not effectively cleaned, carbon deposits and impurities will clog the catalytic converter, leading to increased exhaust back pressure and increased engine exhaust resistance. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency automotive three-way catalytic converter cleaning device to solve the problem mentioned in the background art that current cleaning devices on the market cannot effectively clean the inside of the three-way catalytic converter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency automotive three-way catalytic converter cleaning device, comprising a cleaning tank, with first support frames at both ends inside the cleaning tank; an electric telescopic rod is installed at one end of the top of the cleaning tank, and a piston plate is provided at the output end of the electric telescopic rod, the piston plate being slidably connected inside the cleaning tank; a first one-way valve is installed at one end of one side of the cleaning tank, one end of the first one-way valve being connected to a rotary joint, the other end of the rotary joint being connected to a water outlet pipe; a drain outlet is provided at one end of the cleaning tank; a second one-way valve connected to the drain outlet is installed at one end of the other side of the cleaning tank; and a rotating assembly for driving the water outlet pipe to rotate is provided inside the cleaning tank.

[0006] Preferably, the rotating assembly includes a first piston rod disposed at the bottom of the cleaning tank, a second piston rod slidably connected inside the first piston rod and connected to the bottom of the piston plate, a third piston rod connected to the first piston rod through a hollow tube on the inner side of the cleaning tank, and a fourth piston rod slidably connected inside the third piston rod.

[0007] Preferably, the inner sides of the cleaning tank are also provided with slide rails at both ends, and the two slide rails are slidably connected with racks. The racks are meshed with rotating gears provided on the outer surface of the water outlet pipe, and one end of the racks is connected to one end of the fourth piston rod through a connecting plate.

[0008] Preferably, the water outlet pipe has water outlets on all four sides of the end away from the rotary joint, and the water outlets are distributed at equal angles around the center point of the water outlet pipe.

[0009] Preferably, the cleaning box has a door on one side, and a sealing ring is provided at the joint between the door and the cleaning box.

[0010] Preferably, each of the two first support frames is provided with a second support frame at its top, and the two second support frames and the two first support frames are fixed together by fasteners.

[0011] Preferably, the piston plate is provided with limiting rods that are slidably connected to the inside of the cleaning tank on all four sides of its top, and the four limiting rods are symmetrically arranged.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By connecting a cleaning fluid storage tank to one end of the first one-way valve, the cleaning fluid is drawn into the three-way catalytic converter and cleaned by the lifting and lowering of the piston plate. This effectively removes carbon deposits and chemical complexes adhering to the three-way catalytic converter, restores the catalytic converter's exhaust gas purification function, reduces the emission of harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides in the exhaust gas, making it easier to meet exhaust emission standards. It can also reduce the problem of increased exhaust back pressure caused by blockage of the three-way catalytic converter, improve engine combustion efficiency, and alleviate the phenomenon of weak acceleration.

[0013] By raising and lowering the piston plate, the cleaning fluid after cleaning is discharged from the second one-way valve, and the waste liquid after cleaning is discharged in time to avoid the waste liquid remaining in the three-way catalytic converter. It can also prevent the waste liquid from flowing back and prevent the removed carbon deposits, impurities and other pollutants from adhering to the three-way catalytic converter or pipelines again.

[0014] The rotating component is designed to drive the water outlet pipe to rotate inside the three-way catalytic converter. During the rotation, the water flow forms a dynamic scouring force, which, combined with the water pressure, enhances the ability to remove stubborn carbon deposits. It is especially efficient at cleaning impurities attached to the pores, reducing pollutant residue and restoring the exhaust flow of the catalytic converter. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides the following technical solution: a high-efficiency automotive three-way catalytic converter cleaning device: Example 1: As Figures 1-6As shown, the first one-way valve 4, the second one-way valve 15, and the piston plate 3 can be used to clean the inside of the three-way catalytic converter. The cleaning tank 1 has a first support frame 2 at both ends inside. An electric telescopic rod is installed at one end of the top of the cleaning tank 1, and a piston plate 3 is installed at the output end of the electric telescopic rod. The piston plate 3 is slidably connected to the inside of the cleaning tank 1. A first one-way valve 4 is installed at one end of one side of the cleaning tank 1. One end of the first one-way valve 4 is connected to a rotary joint 5, and the other end of the rotary joint 5 is connected to a water outlet pipe 6. A drain outlet 14 is opened at one end of the cleaning tank 1. A second one-way valve 15 connected to the drain outlet 14 is installed at one end of the other side of the washing tank 1. Water outlets 16 are provided around the end of the water outlet pipe 6 away from the rotary joint 5, and the outlets 16 are evenly distributed around the center point of the water outlet pipe 6. A door is provided on one side of the washing tank 1, and a sealing ring is provided at the joint between the door and the washing tank 1. A second support frame 17 is provided on the top of each of the two first support frames 2, and the two second support frames 17 are fixed to the two first support frames 2 by buckles. Limiting rods that slide inside the washing tank 1 are provided around the top of the piston plate 3, and the four limiting rods are symmetrically arranged (e.g., ...). Figures 1-3 (As shown).

[0019] The three-way catalytic converter to be cleaned is placed on the two first support frames 2, and then the second support frame 17 is connected to the first support frame 2 via a fastener, thereby fixing the three-way catalytic converter (e.g., ...). Figures 3-5 (As shown), then connect the cleaning fluid storage tank to one end of the first one-way valve 4, and then activate the electric telescopic rod to drive the piston plate 3 to move upward, creating a negative pressure inside the cleaning tank 1. At this time, the first one-way valve 4 opens under the action of the negative pressure, and the second one-way valve 15 closes due to its one-way conduction characteristic. The cleaning fluid is drawn into the rotary joint 5 and the outlet pipe 6. When the electric telescopic rod pushes the piston plate 3 downward, the pressure inside the cleaning tank 1 increases, the first one-way valve 4 closes, and the cleaning fluid enters the three-way catalytic converter through the outlet pipe 6 under pressure (as shown). Figure 6 As shown), this cleans the interior, and the waste liquid after cleaning is finally discharged from the drain outlet 14 and the second one-way valve 15 (as shown). Figure 4 As shown in the figure, the limit rod ensures that the piston plate 3 rises and falls smoothly and avoids deviation, while the door and sealing ring can ensure the stability of the internal pressure of the cleaning tank 1, prevent the cleaning fluid from leaking, and improve the overall sealing performance.

[0020] Example 2: Figures 3-5As shown, unlike Embodiment 1, the rotating assembly can drive the water outlet pipe 6 to rotate inside the three-way catalytic converter. The cleaning tank 1 is equipped with a rotating assembly that drives the water outlet pipe 6 to rotate. The rotating assembly includes a first piston rod 7 located at the bottom of the cleaning tank 1. A second piston rod 8, which is slidably connected to the bottom of the piston plate 3, is located inside the first piston rod 7. A third piston rod 9, which is connected to the first piston rod 7 via a hollow tube, is located inside the cleaning tank 1. A fourth piston rod 10 is slidably connected inside the third piston rod 9. Slide rails 11 are also provided at both ends inside the cleaning tank 1. A rack 12 is slidably connected inside the two slide rails 11. The racks 12 are meshed with rotating gears 13 located on the outer surface of the water outlet pipe 6. One end of the rack 12 is connected to one end of the fourth piston rod 10 via a connecting plate.

[0021] As the piston plate 3 descends, it also causes the second piston rod 8 to slide inside the first piston rod 7, thereby compressing the air inside the first piston rod 7. Subsequently, under the action of the hollow tube, it delivers the air to the third piston rod 9, thereby pushing the fourth piston rod 10 to move, which in turn causes the rack 12 to slide between the slide rails 11 (e.g., Figures 3-5 (As shown), then the rotating gear 13 rotates, thereby causing the water outlet pipe 6 to rotate synchronously inside the three-way catalytic converter. During the rotation of the water outlet pipe 6, the water outlet 16 on its surface sprays cleaning fluid at multiple angles. Combined with the pressure difference formed by the rise and fall of the piston plate 3, this achieves all-round flushing of the inside of the three-way catalytic converter (as shown). Figure 6 (As shown).

[0022] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
