The existence of the universal wheels 19 facilitates the movement of the after-treatment regeneration machine housing 1, and the application scenarios are more extensive. Cabinet doors 20 are hinged on both sides of the front surface of the after-treatment regeneration machine housing 1. The existence of the cabinet door 20 protects the parts in the inner cavity of the after-treatment regeneration machine housing 1 and makes the appearance more beautiful.

[0022] The diesel heater 2 is arranged at the left end of the top surface of the post-processing regeneration machine housing 1. The diesel heater 2 is provided with a temperature sensor 21 and an ignition device 22. The temperature sensor 21 and the ignition device 22 are both electrically connected to the PLC controller 3. The temperature sensor 21 is used to detect the temperature of the diesel heater 2 in real time, and the ignition device 22 is used to ignite the diesel heater 2. The diesel heater 2 is electrically connected to the PLC controller 3. The PLC controller 3 is arranged at the right end of the top surface of the post-processing regeneration machine housing 1. The PLC controller 3 is provided with a touch screen 23 and a plurality of buttons 24. The setting of the touch screen 23 and the buttons 24 makes the PLC controller 3 more efficient in controlling the frequency converter 16, the diesel heater 2 and the oil pump 18, etc., and improves the intelligence of the device.

[0023] The left end of the diesel heater 2 is connected to the pneumatic automatic opening and closing tee 4, which includes a first outlet 5 at the left end, a second outlet 6 at the right end, and a third outlet 7 at the bottom end. A tee baffle 8 is hinged at the right corner above the third outlet 7 of the inner cavity of the pneumatic automatic opening and closing tee 4. The pneumatic pressure pushes the tee baffle 8 to rotate upward from a horizontal state to a vertical state. When the tee baffle 8 changes from a horizontal state to a vertical state, the pneumatic pressure enters from the third outlet 7 and goes out along the first outlet 5 to enter the workpiece 10. The first outlet 5 of the pneumatic automatic opening and closing tee 4 is connected to the workpiece 10 through a tray 9. The third outlet 7 of the pneumatic automatic opening and closing tee 4 is connected to the gas tank 12 at the front left side of the inner cavity of the post-processing regeneration machine housing 1 through a first pipeline 11. The gas tank 12 is connected to an external air compressor, and the gas tank 12 is used to provide pneumatic pressure to the diesel heater 2. An air intake solenoid valve 25 is provided at one end of the gas tank 12 connected to the external air compressor, which is used to control the air intake rate. A purge solenoid valve 26 is provided on the first pipeline 11 connecting the gas tank 12 to the third outlet 7. A pressure relief solenoid valve 27 and a second air pressure sensor 28 are also provided on the gas tank 12. The air intake solenoid valve 25, the purge solenoid valve 26, the pressure relief solenoid valve 27 and the second air pressure sensor 28 are all electrically connected to the PLC controller 3. The pressure relief solenoid valve 27 is used to relieve the pressure inside the gas tank 12, and the second air pressure sensor 28 is used to detect the air pressure of the gas tank 12 in real time.

[0024] The right end of the diesel heater 2 is connected to the fan 14 at the right rear part of the inner cavity of the post-processing regeneration machine housing 1 through the second pipeline 13. The second pipeline 13 is provided with a first air pressure sensor 15, and the first air pressure sensor 15 is used to detect the air pressure of the second pipeline 13. The fan 14 is connected to the inverter 16 located at the front side of the fan 14, and the inverter 16 is electrically connected to the PLC controller 3. The PLC controller 3 controls the inverter 16 to control the air volume and wind speed of the fan 14.

[0025] The right end of the diesel heater 2 is also connected to the oil pump 18 at the rear left side of the inner cavity of the post-processing regeneration machine housing 1 through an oil pipe 17. The oil pump 18 is connected to an external oil tank. The oil pump 18 is electrically connected to the PLC controller 3. The PLC controller 3 controls the frequency of the oil pump 18 and ultimately controls the amount of oil inside the diesel heater 2.

[0026] The working process of the utility model is as follows:

[0027] Turn on the PLC controller 3, which is electrically connected to the diesel heater 2, the air intake solenoid valve 25, the purge solenoid valve 26, the pressure relief solenoid valve 27, the frequency converter 16, and the oil pump 18;

[0028] The gas tank 12 is connected to an external air compressor, and the oil pump 18 is connected to an external oil tank. The oil inside the oil pump 18 enters the diesel heater 2 along the oil pipe 17. The PLC controller 3 controls the frequency converter 16 to control the air volume and wind speed of the fan 14 to enter the diesel heater 2. The ignition device 22 on the diesel heater 2 is started, and the diesel heater 2 starts to heat, maintaining the temperature at 600-800°C. When the air pressure inside the gas tank 12 pushes the three-way baffle 8 from a horizontal state to a vertical state, the air pressure enters from the third outlet 7 and goes out along the first outlet 5 to enter the workpiece 10, thereby cleaning the carbon deposits on the workpiece 10.

[0029] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes. The implementation modes can still be changed within the knowledge scope of ordinary technicians in the field.
