Description

Technical Field

[0001] This utility model relates to the field of three-way catalytic converter cleaning technology, and in particular to a high-efficiency cleaning structure for automotive three-way catalytic converters. Background Technology

[0002] The three-way catalytic converter is a key component installed in the car's exhaust system. It can convert harmful gases in the exhaust into harmless substances. To prevent it from failing due to blockage caused by carbon deposits, it needs to be cleaned regularly to ensure the exhaust purification effect, reduce pollutant emissions, and thus improve vehicle performance.

[0003] However, traditional automotive catalytic converter cleaning equipment only uses tap water for cleaning. Since tap water lacks the ability to specifically dissolve carbon ash, the carbon ash is difficult to remove effectively during the cleaning process, resulting in extremely poor cleaning results and failing to meet the needs of deep cleaning of automotive catalytic converters. Secondly, traditional cleaning equipment cannot thoroughly clean the inner wall of the catalytic converter during cleaning. Due to the limitations of the equipment structure, there are many blind spots during the cleaning process, which prevents critical parts such as precious metals from being fully cleaned, thus affecting the performance and service life of the automotive catalytic converter.

[0004] Prior art 1 (Chinese patent application number CN201921645857.3, application date 2019-09-29) discloses a cleaning mechanism for an automotive three-way catalytic converter. A connector is fixedly connected to one end of the three-way catalytic converter body. Two first connecting blocks are fixedly connected to the side wall of the connector. A sealing groove is opened at the end of the connector away from the three-way catalytic converter body. A connecting device is fixedly connected to the end of the connector away from the three-way catalytic converter body. The connecting device includes a cleaning cylinder. The side wall of the cleaning cylinder is connected to the cleaning device. The cleaning device includes a regulating valve. By sleeved with a tap water hose on the surface of the connecting pipe, the regulating valve is opened to allow tap water to enter the cleaning cylinder through the connecting pipe and the regulating valve. The water inside the cleaning cylinder enters the interior of the three-way catalytic converter body under the water pressure of the tap water inside the tap water pipe, and the dirt inside the three-way catalytic converter body is cleaned by the flowing tap water.

[0005] Prior art 2 (Chinese patent application number CN201720682645.7, application date 2017-06-13) discloses a special device for cleaning and maintaining a three-way catalytic converter for automobiles. The base has a waste liquid tank and a medicine tank on both sides of the top. A water pump is fixed on the top of the medicine tank, and its outlet is connected to the first connector through an outlet pipe. A waste liquid pipe is connected to the inner wall of the top of the waste liquid tank. This device can seal and clamp the three-way catalytic converter body for cleaning. By adjusting the second limiting rod, the retaining ring is clamped to the air intake pipe. The adjusting block is moved to make the retaining ring clamp the first fixing ring. The first connector can seal and clamp the air intake pipe. The structure of the second connector is the same as that of the first connector, sealing and clamping the air outlet pipe. The water pump can be started to clean the three-way catalytic converter body. The structure is simple and the cleaning and maintenance effect is good. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] like Figures 1-6 As shown, the present invention proposes a high-efficiency cleaning structure for automotive three-way catalytic converters, which includes a workbench 1, a high-efficiency cleaning component 2 on the workbench 1, an inverted L-shaped mounting bracket 3 on the side of the workbench 1 away from the high-efficiency cleaning component 2, and a flipping clamping component 4 on the inverted L-shaped mounting bracket 3.

[0019] The high-efficiency cleaning component 2 includes a housing 21 mounted on the workbench 1. The housing 21 provides a mounting base for the liquid storage tank 22 and the heating tube 23. The liquid storage tank 22 is installed inside the housing 21 and stores the three-way catalytic converter cleaning fluid. The heating tube 23 is wound around the outer wall of the liquid storage tank 22 and heats the cleaning fluid in the liquid storage tank 22 to improve the carbon ash dissolution efficiency. A protective plate 24 is installed on the top of the housing 21 corresponding to the position of the heating tube 23. A lid 25 is installed on the top of the liquid storage tank 22 to seal the top of the liquid storage tank 22 and prevent the three-way catalytic converter cleaning fluid from evaporating and impurities from entering the interior of the liquid storage tank 22.

[0020] A liquid pump 26 is installed on the workbench 1 on one side of the outer casing 21. The liquid pump 26 draws cleaning fluid from the storage tank 22 through the liquid pumping pipe 27 and delivers it to the sprayer 29 through the liquid supply pipe 210. The liquid pump 26 is provided with a liquid pumping pipe 27 on one side, and one end of the liquid pumping pipe 27 passes through the tank cover 25. The liquid pumping pipe 27 realizes the delivery of cleaning fluid from the storage tank 22 to the liquid pump 26. A second mounting bracket 28 is provided on the top surface of the inverted L-shaped mounting bracket 3. The second mounting bracket 28 provides a mounting base for the sprayer 29. The sprayer 29 is provided at the bottom of the second mounting bracket 28. The liquid supply pipe 210 is provided between the liquid pump 26 and the sprayer 29. The liquid supply pipe 210 connects the liquid pump 26 and the sprayer 29 to deliver the cleaning fluid.

[0021] A waste liquid guide shell 211 is installed on the workbench 1 at the position corresponding to the sprayer 29. The waste liquid guide shell 211 guides the waste liquid generated during the cleaning process to the waste liquid collection tank 212. A waste liquid collection tank 212 is installed at the bottom of the workbench 1 at the position corresponding to the waste liquid guide shell 211. The waste liquid collection tank 212 collects the waste liquid and prevents the waste liquid from flowing randomly and causing pollution.

[0022] The flipping clamping assembly 4 includes a rotating shaft 41 mounted on an inverted L-shaped mounting bracket 3. The rotating shaft 41 provides a mounting base for gear 42 and rotating plate 45. Gear 42 is sleeved on the outside of the rotating shaft 41. A motor 43 is mounted on the inverted L-shaped mounting bracket 3 at the bottom of the rotating shaft 41. A gear 44 meshes with gear 42 at the transmission end of the motor 43. The motor 43 drives gear 44 to rotate. Gear 44 transmits power to gear 42 through meshing, thereby driving the rotating shaft 41 to rotate. A rotating plate 45 is mounted on one end of the rotating shaft 41. When the rotating shaft 41 rotates, it drives the rotating plate 45 to rotate synchronously.

[0023] Motor 2 46 is installed in the square slots at the top and bottom of the rotating plate 45. Gear 3 47 is installed at the drive end of each motor 2 46, providing rotational power to the gear 3 47. Racks 48 are meshed on both sides of the gear 3 47, transmitting the power of the motor 2 46 to the racks 48 through meshing. A pair of guide rails 49 are installed in the square slots at the top and bottom of the rotating plate 45, with several racks 48 slidably mounted on the guide rails 49. The guide rails 49 guide the racks 48, ensuring their proper functioning. To ensure stability during movement, each rack 48 is equipped with a connecting frame 411. The connecting frame 411 connects the rack 48 and the V-shaped clamping seat 412, transmitting the movement of the rack 48 to the V-shaped clamping seat 412, which in turn drives the V-shaped clamping seats 412 on both sides. Each connecting frame 411 has a V-shaped clamping seat 412 on one side. The V-shaped clamping seat 412 is used to securely clamp the top and bottom of the automotive three-way catalytic converter, preventing accidental shaking during cleaning. Protective plates 410 are provided on the rotating plate 45 at the positions corresponding to the square grooves.

[0024] Working principle: When the operator starts cleaning, the automotive catalytic converter to be cleaned is first placed in the tilting clamping assembly 4. Then, the second motor 46 in the square slots at the top and bottom of the rotating plate 45 is started. The second motor 46 starts running and drives the third gear 47 to rotate. When the third gear 47 rotates, it transmits power to the racks 48 through meshing with the racks 48 on both sides, driving the racks 48 on both sides to move along the guide rail 49. During the movement of the racks 48, the connecting bracket 411 moves together, thereby causing the V-shaped clamping seats 412 on both sides to move closer to the middle until the top and bottom of the automotive catalytic converter are firmly clamped, completing the cleaning process. After clamping, the high-efficiency cleaning component 2 is activated to prepare for cleaning. First, the heating tube 23 wrapped around the outer wall of the storage tank 22 is started. The heating tube 23 starts working and heats the three-way catalytic converter cleaning solution in the storage tank 22. After the three-way catalytic converter cleaning solution is heated to a suitable temperature, the liquid pump 26 is started. The liquid pump 26 draws the cleaning solution from the storage tank 22 through the liquid pumping pipe 27. The cleaning solution is transported to the sprayer 29 through the liquid supply pipe 210. Then, the sprayer 29 is turned on and sprays the heated three-way catalytic converter cleaning solution onto the inner wall of the three-way catalytic converter below. The heated three-way catalytic converter cleaning solution can effectively improve the dissolution efficiency of carbon ash.

[0025] During the cleaning process, a certain amount of waste liquid is generated. This waste liquid flows down the waste liquid guide shell 211 on the workbench 1 and eventually falls into the waste liquid collection bucket 212 at the bottom of the workbench 1, thus collecting the waste liquid and preventing it from flowing randomly and causing pollution. To prevent insufficient cleaning of the precious metals inside the three-way catalytic converter, it is also necessary to flip it during the cleaning process. The motor 43 drives the gear 44 to rotate. The gear 44, through meshing with the gear 42, transmits power to the gear 42, thereby driving the rotating shaft 4. 1. Rotation of the rotating shaft 41 drives the rotating plate 45 to rotate, causing the three-way catalytic converter clamped on the rotating plate 45 to flip over, flipping the original bottom end to the top. Then, the sprayer 29 is started again to backwash the flipped three-way catalytic converter to ensure that the carbon ash inside is thoroughly washed away. After the cleaning work is completed, the high-efficiency cleaning component 2 is turned off first, and then the motor 2 46 is controlled to reverse, so that the V-shaped clamp 412 releases its clamp on the three-way catalytic converter, and the operator can easily remove the cleaned car three-way catalytic converter.
