One end of the first venturi tube is fixed to the steam discharge port 110; preferably, one axial end of the first venturi tube first inlet section 801 is provided with a flange, and the steam discharge port 110 of the containing box 102 is provided with a flange, and the first inlet section 801 is connected with the flange on the containing box 102 through the flange.

As shown in fig. 11, 12 and 13, the sealing cover 806 is used to close or open the steam discharge port 110, and the sealing cover 806 is connected to an end of the linear driving mechanism extending toward the steam discharge port. The sealing cover 806 is preferably arranged in the accommodating box 102 instead of being selectively arranged in the first inlet section 801, and the advantage of this arrangement is that when the cylinder 805 is retracted to close the steam discharge port 110 by the sealing cover 806, the inner wall surface of the accommodating box 102 is made to abut against the sealing cover 806, and when the pressure of the gas (for example, the pressure of the steam) in the accommodating box 102 is applied to the sealing cover 806, the accommodating box 102 can form a limit effect on the sealing cover 806, so that the pressure of the gas can be prevented from being transmitted to the air pressure through the sealing cover, and the axial bearing of the first inlet section 801 from the pressure in the accommodating box 102 can be prevented. If the sealing cap 806 is disposed in the first inlet section 801, when the steam discharge port 110 is closed by the air cylinder 805, the pressure in the housing case 102 acts on the air cylinder 805 through the sealing cap 806 because the sealing cap 806 loses the limiting action of the other limiting member, and the air cylinder 805 transmits the acting force to the first inlet section 801, which may have adverse effects of damaging the first inlet section 801.

In order to increase the cooling efficiency, the cooling pipe 809 preferably adopts a spiral-shaped cooling pipe 809, which spiral-shaped cooling pipe 809 surrounds the cylinder piston rod in the first inlet section 801.

The cleaning process of the workpiece by adopting the cleaning machine provided by the invention comprises the following steps:
step one, vacuumizing and heating the cleaning machine through a vacuumizing device. That is, the vacuum pump 201 is turned on to vacuum the liquid storage tank 100, the first liquid storage chamber 101, the housing tank 102, the waste liquid temporary storage tank 106, the condensate storage tank 107, the first condenser 204, the second condenser 205, the third condenser 206, the first venturi tube, and the second venturi tube 810, respectively. The heating pipe 108 heats the cleaning liquid in the first liquid storage chamber 101 to generate steam. When the vacuum degree and the temperature of the cleaning liquid reach set values, the equipment runs idle.
Step two, the workpiece is preliminarily cleaned by ultrasonic in the accommodating box 102. The workpiece to be cleaned is placed in the charging basket 412, the charging basket 412 is integrally pushed into the frame 406 through the material port 103 and the material inlet and outlet 409, the rotary driving part 321 is started, the safety door body 309 reaches the material port 103, and the telescopic propping part 320 is started to compress the safety door body, so that the material port 103 is ensured to be closed. The vacuum pump 201 is started to again evacuate the holding tank 102. The liquid feeding pump 600 is started, the high-temperature hydrocarbon cleaning liquid in the first liquid storage chamber 101 is fed into the accommodating box 102 through the first liquid feeding pipe 601 and the second liquid feeding pipe 603, meanwhile, the motor 400 works to drive the frame 406 to rotate, so that the workpiece is fully soaked in the hydrocarbon cleaning liquid, when the liquid level of the hydrocarbon cleaning liquid in the accommodating box 102 reaches a set value, the ultrasonic rod 500 works, the ultrasonic rod 500 generates cavitation, so that the hydrocarbon cleaning liquid flows and tens of thousands of high-pressure vacuum bubbles are generated, and the energy generated by instant explosion of the high-pressure vacuum bubbles continuously impacts the surface of the workpiece, so that dirt on the surface of the workpiece and in gaps is peeled off rapidly.
Step three, the workpiece is sprayed and cleaned at high pressure in the accommodating box 102 by spraying cleaning liquid. The recovery pump 609 is turned on to pump the hydrocarbon cleaning fluid in the holding tank 102 through the first return pipe 610 and the filter 616, and through the second return pipe 612 to the recycle tank 105.

After the high-pressure jet cleaning, the hydrocarbon cleaning liquid is sent to a recycling tank by a recycling pump 609.
Step four, the workpiece is subjected to steam bath cleaning in the accommodating box 102.
