[0018] See also Figure 1-2The utility model provides an embodiment: an air conditioning pipeline assembly cleaning device, which includes a cleaning tank 101, a first rinsing tank 201, a second rinsing tank 202, a clean water tank 301 and a compressed air blowing platform 801, wherein the cleaning tank 101, the first rinsing tank 201, the second rinsing tank 202 and the clean water tank 301 are arranged in sequence, the cleaning tank 101 is filled with an aluminum degreasing agent, the first rinsing tank 201, the second rinsing tank 202 and the clean water tank 301 are filled with clean water, and the first rinsing tank 201 and the second rinsing tank 202 are connected by a second overflow The flow channel 402 is connected, the second rinsing tank 202 is connected to the clean water tank 301 through the first overflow channel 401, and a water inlet is also provided on the clean water tank 301. A wastewater recovery tank 701 is connected to the first rinsing tank 201, and the two are connected through a third overflow channel 403. The compressed air blowing platform 801 is arranged at the rear end of the clean water tank 301, and is used to blow dry the air-conditioning pipeline assembly after cleaning; at the same time, the compressed air blowing platform 801 can also be connected to the first rinsing tank 201, the second rinsing tank 202 and the clean water tank 301 through air pipes.

[0019] In order to facilitate the loading and cleaning of multiple air conditioning pipeline assemblies at one time, a cleaning frame 601 is provided for centralized cleaning. The cleaning frame 601 is placed in and taken out of the cleaning tank, rinsing tank or clean water tank by a lifting and hoisting device. At the same time, in order to facilitate movement, a transport guide rail 501 is provided above the cleaning tank, rinsing tank and clean water tank, and the cleaning frame 601 can move back and forth along the transport guide rail 501.

[0020] The working principle of the utility model is as follows: the cleaning tank 101 is filled with aluminum degreaser, which is used to decompose oxides and dirt. The first rinsing tank 201, the second rinsing tank 202 and the clean water tank 301 are filled with clean water, which is used to clean the aluminum degreaser on the surface of the pipeline. The brazed air-conditioning pipeline products are placed in the cleaning frame 601, transported into the cleaning tank 101 by the lifting equipment, and the air-conditioning pipeline products are fully immersed in the aluminum degreaser for five minutes. The aluminum degreaser removes oxides and dirt at the brazing of the air-conditioning pipeline, and the surface of the air-conditioning pipeline restores the original color of the aluminum profile. The lifting equipment lifts the cleaning frame 601 in the cleaning tank 101, stands for 10 seconds, and lowers the height of the left and right sides of the cleaning frame 601 respectively, and the aluminum degreaser on the surface of the air-conditioning pipeline product and inside the pipeline flows into the cleaning tank 101 for recycling. The lifting and lifting equipment transports the cleaning frame 601 into the first rinsing tank 201, and the air conditioning pipeline products are fully immersed in clean water. After standing for 5 seconds, the lifting and lifting equipment lifts the cleaning frame 601 in the first rinsing tank 201, and stands for 10 seconds, and lowers the height of the left and right sides of the cleaning frame 601 respectively, and the clean water on the surface of the air conditioning pipeline products and inside the pipeline flows into the first rinsing tank 201 for recycling. The lifting and lifting equipment transports the cleaning frame 601 into the second rinsing tank 202, and the air conditioning pipeline products are fully immersed in clean water. After standing for 5 seconds, the lifting and lifting equipment lifts the cleaning frame 601 in the second rinsing tank 202, and stands for 10 seconds, and lowers the height of the left and right sides of the cleaning frame 601 respectively, and the clean water on the surface of the air conditioning pipeline products and inside the pipeline flows into the second rinsing tank 202 for recycling. The lifting equipment transports the cleaning frame 601 into the clean water tank 301, and the air conditioning pipeline product is fully immersed in the clean water and left to stand for 5 seconds. The lifting equipment lifts the cleaning frame 601 in the clean water tank 301, and leaves it to stand for 10 seconds. The height of the left and right sides of the cleaning frame 601 is lowered respectively, and the clean water on the surface of the air conditioning pipeline product and inside the pipeline flows into the clean water tank 301 for recycling. The lifting equipment then transports the cleaning frame 601 to the compressed air blowing platform 801, and the compressed air in the platform blows the clean water on the surface of the air conditioning pipeline product dry, and then uses a handheld compressed air gun to blow the clean water on the inner wall of the air conditioning pipeline product dry.

[0021] The top of the clean water tank 301 is a water inlet, which continuously discharges water. Clean water flows into the clean water tank 301. When the water level is higher than the first overflow channel 401, the dirt on the water surface of the clean water tank 301 will flow into the second rinsing tank 202 through the first overflow channel 401. When the water level in the second rinsing tank 202 is higher than the second overflow channel 402, the dirt on the water surface of the second rinsing tank 202 will flow into the first rinsing tank 201 through the second overflow channel 402. When the water level in the first rinsing tank 201 is higher than the third overflow channel 403, the dirt on the water surface of the first rinsing tank 201 will flow into the wastewater recovery tank 701 through the third overflow channel 403.

[0022] The compressed air of the compressed air blowing platform 801 is connected to the clean water tank 301, the second rinsing tank 202, and the first rinsing tank 201 in sequence using air pipes. The compressed air is released in the water in the tank, which can make the water roll and make it easier to clean the air conditioning pipeline.
