The hot air flow is circulated through the circulation component to improve the drying efficiency, and the filter cartridge 41 is cleaned with the cleaning component. Secondly, the discharged hot air flow is processed by the filtering component to separate the water molecules in the hot air flow, and the hot air flow is cooled, and then the air flow is purified and filtered.

[0032] The circulation assembly includes: a circulation fan 2, an air supply pipe 21, a return air pipe 22, a fresh air pipe 23, a guide plate 24 and a heating module 25. The circulation fan 2 is arranged at the top of the drying box 1. The output end of the circulation fan 2 is provided with an air supply pipe 21, the input end of the circulation fan 2 is provided with a return air pipe 22, the fresh air pipe 23 is arranged on the upper surface of the return air pipe 22, the guide plate 24 is arranged on the inner wall of the top of the drying box 1, and the heating modules 25 are fixedly installed on the inner walls of the opposite sides of the drying box 1 respectively. A plurality of shunt pipes 26 are fixedly connected to the air supply pipe 21, and a plurality of shunt pipes 26 are fixedly connected to the air supply pipe 21. They respectively penetrate the drying box 1 and extend to the interior. A plurality of return pipes 27 are respectively provided on the return air duct 22. The bottom ends of the plurality of return pipes 27 respectively penetrate the drying box 1 and the guide plate 24. The guide plate 24 has a trapezoidal cross-section.

[0033] When drying, first start the heating module 25 and set the temperature to preheat the drying box 1, so that the transformer shell can be dried immediately after entering, without waiting for the temperature to rise. After the transformer shell enters the drying box 1, start the circulation fan 2. After the circulation fan 2 is started, air is sucked in from the input end and then discharged from the output end. The air inside the drying box 1 is sucked in through multiple return pipes 27 and return air pipes 22. Since the inside of the drying box 1 is preheated in advance, hot air is sucked in. The sucked hot air is then discharged from the air supply pipe 21 into a plurality of shunt pipes 26. The hot air is sent into the drying box 1 through the shunt pipes 26. The airflow is sent out from the top of the drying box 1 and touches the guide plate 24. The airflow beam is intercepted by the guide plate 24 to slow down the flow rate, avoiding In order to prevent the paint from being blown due to excessive air flow, resulting in uneven distribution of the paint, the air flow beam is divided into air flows flowing to the air ducts on both sides by the guide plate 24, and the baffle 28 can intercept the air flow beam so that the air flow can only flow to the air ducts on both sides, flow out of the air duct and flow downward, and blow onto the heating module 25. The heating module 25 is provided with a shielding plate on the side facing the transformer casing so that the high temperature will not be directly irradiated on the transformer casing. The air flow enters from the top of the heating module 25 and flows out from the bottom, and the air flow is then heated. The heated air flow continues to flow downward, and after touching the transformer casing, it rebounds and flows in the opposite direction, and touches the conveyor belt 11 to diffuse to the surroundings, thereby accelerating the air flow rate at the bottom of the transformer casing, so that the paint at the bottom can dry quickly.

[0034] The filter assembly includes a condenser 3, a water receiving bucket 31, an air filter element 33 and a transfer box 34.

Exhaust pipes 38 are respectively provided at the locations, one ends of the two exhaust pipes 38 are respectively connected to the connecting pipes 37, an exhaust fan 39 is provided near the air inlet 36 inside the separation box 12, a water outlet 310 is provided at the bottom of the water receiving bucket 31, a wind shield plate 311 is provided on the inner wall of the water receiving bucket 31 near the water outlet 310, an S-shaped tube 312 is provided at the bottom of the water outlet 310, a through hole is provided at the top near the middle position of the air filter element 33, the bottom end of the S-shaped tube 312 passes through the through hole and is connected to the inside of the transfer box 34, a filler 313 is provided between the inner wall of the through hole and the S-shaped tube 312, and a valve 314 is provided on the side of the separation box 12 away from the drying box 1, and the valve 314 is connected to the inside of the transfer box 34.

[0035] During drying, the exhaust fan 39 is turned on to extract air, so that the exhaust pipe 38 generates suction, and the airflow at the feed port and the discharge port is sucked away, enters the connecting pipe 37, and enters the separation box 12 from the air inlet 36, first passes through the condenser 3, and the hot air flow contacts the condenser 3 for condensation, flows downward under the action of gravity, falls into the water receiving bucket 31, converges to the water outlet 310 along the water receiving bucket 31, flows into the S-shaped pipe 312 along the water outlet 310, and then flows into the transfer box 34 from the S-shaped pipe 312, and the valve One end of 314 can be connected to a water pipe. After opening valve 314, the water inside transfer box 34 flows out, and the air flow after condensation and cooling flows downward through ventilation groove 32. Wind shield 311 can block the air flow from rushing into drain port 310, to prevent the air pressure from sending the water stored in S-shaped tube 312 into transfer box 34, and pass through air filter element 33 to purify the odor in the air flow, and the purified air is discharged from air outlet 35, so as to prevent the air flow with odor and moisture from being directly discharged into the air, causing air pollution to the workplace.

[0037] When the air is extracted, the outside air enters the return air duct 22 from the fresh air duct 23. The filter cartridge 41 on the fresh air duct 23 can filter the incoming air to prevent debris and dust from entering the drying box 1. When the outside air enters, it passes through the fan blades 43. The fan blades 43 rotate under the drive of the airflow. The fan blades 43 drive the rotating rod 42 to rotate. The retaining frame 48 can improve the concentricity. The setting of the rotating bearing 49 supports the rotating rod 42 and makes it rotate more smoothly. When the rotating rod 42 rotates, it drives the connecting rod 44 to rotate. The connecting rod 44 drives the rotating plate 45 to rotate inside the limiting ring 47. The limiting ring 47 can limit the rotating plate 45 so that the rotating plate 45 can only move between the limiting ring 47 and the base 4. When the rotating plate 45 rotates, it drives the brush 46 to continuously brush the surface of the filter cartridge 41, so as to clean up the dust and debris on the surface of the filter cartridge 41, avoid the mesh of the filter cartridge 41 being blocked, and affect the circulation of the airflow. At the same time, cooperate with the extraction of hot air to maintain the temperature inside the drying box 1.
