as shown in fig. 11, 12 and 13, the first venturi tube includes a first inlet section 801, a first throat 802, and a first diffuser section 803, a first opening is provided on a circumferential surface of the first inlet section 801 and connected to one end of the first throat 802, a second opening is provided on a circumferential surface of the first diffuser section 803 and connected to the other end of the first throat 802, an axial direction of the first inlet section 801 is parallel to a longitudinal direction of the tank 100, an axial direction of the first throat 802 is parallel to a width direction of the tank 100, and an axial direction of the first diffuser section 803 is parallel to a height direction of the tank 100, so that the axial direction of the first venturi tube in the present embodiment is not as same as the axial direction of the conventional venturi tube (the axial directions of the three sections of the conventional venturi tube are in the same line), and the reason for adopting such a configuration is that, on the one hand, a linear driving mechanism is disposed around the tank to avoid occupying its installation position, making the structure of the apparatus compact, and, on the other hand, it is convenient to install a linear driving mechanism to control the opening or closing of the steam sealing cap 110 by the linear driving mechanism. One end of the first venturi tube is fixed to the steam discharge port 110; preferably, an axial end of the first inlet section 801 of the first venturi tube is provided with a flange, a flange is provided at the steam discharge port 110 of the accommodating case 102, and the first inlet section 801 is connected with the flange on the accommodating case 102 through the flange.

As shown in fig. 11, 12 and 13, a 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 this arrangement has an advantage that when the cylinder 805 is retracted to cause the sealing cover 806 to close the steam discharge port 110, the inner wall surface of the accommodating box 102 abuts against the sealing cover 806, and when the pressure of the gas (e.g. the pressure of the steam) inside the accommodating box 102 is applied to the sealing cover 806, the accommodating box 102 can limit the sealing cover 806, so that the pressure of the gas can be prevented from being transmitted to the gas pressure through the sealing cover, and the axial direction of the first inlet section 801 can be prevented from bearing the pressure in the accommodating box 102. If the sealing cover 806 is disposed in the first inlet section 801, when the steam discharge port 110 is closed by the cylinder 805, since the sealing cover 806 loses the restraining effect of other restraining members, the pressure in the accommodating case 102 acts on the cylinder 805 through the sealing cover 806, and the cylinder 805 transmits the force to the first inlet section 801, which may have an adverse effect of damaging the first inlet section 801.

The support assembly supports the piston rod of the cylinder 805, so that the coaxiality of the piston rod of the cylinder 805 and the steam discharge port 110 is kept, the axial deviation of the piston rod caused by the sealing cover 806 loaded at the other end of the piston rod is avoided, the reliability of sealing the sealing cover 806 on the steam discharge port 110 is improved, and the cylinder is balanced in the transmission process.

As shown in fig. 11, 12 and 13, a cooling pipe 809 is disposed in the first venturi tube, and the cooling pipe 809 is disposed in the first inlet section 801 and the first diffusion section 803, and since steam is formed by the hydrocarbon cleaning liquid, the main component of the steam is hydrocarbon, and the cooling pipe 809 is used for accelerating cooling of the steam discharged from the steam discharge port 110 into the first venturi tube, so that the steam becomes liquid, and recovering the formed liquid. To increase the cooling efficiency, the cooling pipe 809 preferably takes the form of a spiral cooling pipe 809, and in the first inlet section 801, such spiral cooling pipe 809 is wrapped around the cylinder piston rod. The cooling pipe 809 is filled with a cooling medium, which may be water, oil, or other medium that can absorb heat and flow through the pipe. The output end of the first venturi tube is connected with the condensate storage tank 107, the first diffusion section 803 is provided with a pipeline connected with the condensate storage tank 107, the first diffusion section 803 is connected with the condensate storage tank 107 through the pipeline, steam passing through the first venturi tube is changed into liquid and then is discharged into the condensate storage tank 107, and the steam is discharged into the liquid storage tank 100 through the condensate storage tank 107 for recycling.

There is a possibility that the steam passing through the first venturi tube may not be completely changed into liquid, and there is a small amount of steam, and therefore, in the present embodiment, a second venturi tube 810 is provided, and the second venturi tube 810 is connected between the first venturi tube and the condensate storage tank 107, and a cooling water jacket 811 is provided on the second venturi tube 810.

As shown in fig. 1, 11, 12 and 13, the operation process of the steam discharge control device is as follows: when the steam in the accommodating box 102 needs to be discharged, the piston rod of the control cylinder 805 extends out, the piston rod pushes the sealing cover 806 to leave the steam discharge port 110, so that the steam discharge port 110 is in an open state, steam rapidly floods into the first inlet section 801 from the steam discharge port 110 due to the venturi effect of the first venturi tube, oil stains remained on the surface of the workpiece are taken away by the rapidly flowing steam, and the rapidly volatilized steam has a drying effect on the workpiece, so that the workpiece is not only cleaned, but also dried, cleaning liquid does not remain on the surface of the workpiece due to volatilization of the steam, and therefore safety is improved when the workpiece is taken out. As can be seen from the above description, the steam discharge control device of the present invention functions as: cleaning the workpiece, recovering the cleaning liquid (the recovery of the cleaning liquid is stated above and is not described herein), and improving the safety.

The process of cleaning the workpiece by adopting the cleaning machine of the invention is as follows:

step one, vacuumizing and heating the cleaning machine through a vacuumizing device. That is, the vacuum pump 201 is turned on to evacuate the liquid storage tank 100, the first liquid storage chamber 101, the accommodating 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. An added pipe 108 heats the cleaning liquid in the first reservoir 101 to generate steam from the cleaning liquid. When the vacuum degree and the temperature of the cleaning liquid reach set values, the equipment is in idle operation.

And step two, performing primary cleaning on the workpiece in the accommodating box 102 by ultrasonic. The workpiece to be cleaned is placed into the charging basket 412, the charging basket 412 is integrally pushed into the frame body 406 through the material opening 103 and the material inlet and outlet 409, the rotary driving part 321 is started, the safety door body 309 reaches the material opening 103, the telescopic jacking part 320 is started to compress the safety door body, and the material opening 103 is ensured to be closed. The vacuum pump 201 is started to evacuate the containing box 102 again. 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 operates to drive the frame body 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 operates, the ultrasonic rod 500 generates a cavitation effect, the hydrocarbon cleaning liquid flows and tens of thousands of high-pressure vacuum bubbles are generated, energy generated by instantaneous explosion of the high-pressure vacuum bubbles continuously impacts the surface of the workpiece, and dirt on the surface of the workpiece and in gaps is rapidly peeled off.

And step three, spraying cleaning liquid in the accommodating box 102 at high pressure to clean the workpiece. The recycle pump 609 is turned on to pump the hydrocarbon cleaning fluid in the holding tank 102 through the first return line 610 and the filter 616, and through the second return line 612 to the recycle tank 105. The liquid feeding pump 600 is started, the high-temperature hydrocarbon cleaning liquid in the first liquid storage chamber is fed to the spraying mechanism through the first liquid feeding pipe 603 and the third liquid feeding pipe 605, the hydrocarbon cleaning liquid is sprayed out in a high-pressure mode through the first spraying pipe 702 and the second spraying pipe 703 of the spraying mechanism, and the first spraying pipe 702 and the second spraying pipe 703 form a pair spraying on the workpiece due to the fact that the first spraying pipe 702 and the second spraying pipe 703 are arranged at the upper part and the lower part, and therefore the workpiece is subjected to high-pressure spraying cleaning. After the high pressure jet cleaning, the hydrocarbon cleaning fluid is sent to a recycle tank by a recycle pump 609.

After the hydrocarbon cleaning liquid in the accommodating box 102 is exhausted by the recovery pump 609, the control valve 109 is opened, so that the high-temperature steam in the first liquid storage chamber 101 enters the accommodating box 102 to perform steam bath cleaning on the workpiece, meanwhile, the frame 406 is in a rotating working state, and when the steam in the accommodating box 102 reaches a saturated state, the control valve 109 is closed.

And step five, discharging the steam in the accommodating box 102 and simultaneously drying the workpiece. The piston rod of the control cylinder 805 extends out, the piston rod pushes the sealing cover 806 to leave the steam discharge port 110, so that the steam discharge port 110 is in an open state, steam is rapidly gushed into the first inlet section 801 from the steam discharge port 110 due to the venturi effect of the first venturi tube, oil stains remained on the surface of the workpiece are taken away by the rapidly flowing steam, and the rapidly volatilized steam has a drying effect on the workpiece.

And step six, cleaning the workpiece in the accommodating box 102. The liquid feeding pump 600 is started, and the clean hydrocarbon cleaning liquid in the clean cleaning liquid storage tank 104 is fed into the containing tank 102, so that the frame 406 is in a rotating working state, and the clean hydrocarbon cleaning liquid forms clean cleaning on the workpiece, preferably, the clean hydrocarbon cleaning liquid is sprayed onto the workpiece through the first spraying pipe 702 and the second spraying pipe 703 to form high-pressure spraying clean cleaning on the workpiece. And after the cleaning is finished, the step five is repeatedly executed. The above cleaning process is selected to be executed repeatedly or circularly according to the stubborn degree of dirt on the surface of the workpiece. In the above cleaning process, the order of cleaning is not fixed as described above, and for example, after step two is performed, steps four and five may be performed first, and then step three may be performed.
