[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: an ultrasonic vacuum defoaming machine, including a transparent vacuum chamber 1, a base box 2 fixedly installed at the bottom of the transparent vacuum chamber 1, and an installation cavity 25 provided inside the base box 2. A vacuum pump 4 is fixedly installed inside the installation cavity 25. An operation panel 3 is fixedly installed on the side of the base box 2. A stainless steel vibration panel 23 is fixed between the base box 2 and the transparent vacuum chamber 1, and a vibrator 5 is fixedly installed on one side of the stainless steel vibration panel 23 located in the installation cavity 25. A solenoid valve 24 is connected and installed between the transparent vacuum chamber 1 and the base box 2. The solenoid valve 24 is installed on the stainless steel vibration panel 23, and an air inlet is provided at one end of the solenoid valve 24 that penetrates into the transparent vacuum chamber 1. During operation, vacuum pump 4 draws air to -95 kPa to initially expand the bubble volume; simultaneously, ultrasonic pulse mode is activated, vibrating for 3 minutes and then shut off to break up residual tiny bubbles; at the same time, ultrasonic waves are activated to heat the resin, which can accelerate liquid flow. After the ultrasonic waves stop, vacuum pump 4 continues to work to remove remaining bubbles. By controlling the alternating operation of vacuum and ultrasonic waves through timing, energy interference is avoided, improving degassing efficiency by more than 30%, achieving a bubble removal rate of >95% for bubbles smaller than 0.05 mm, shortening the processing time to 10-20 minutes, supporting materials with a viscosity range of 100-10,000 cps, compatible with laboratories and small production lines, and with low-power vacuum pump 4 and intermittent ultrasonic operation mode, energy consumption is reduced by 40%.

[0026] In this embodiment, the inner wall of the transparent vacuum chamber 1 is made of polished stainless steel, and the polished stainless steel material prevents air bubbles from adhering to the inner wall of the transparent vacuum chamber 1.

[0027] In this embodiment, the base box 2 includes a lower cover 26 and an upper cover 21, which are fixedly connected by screws. The stainless steel vibration panel 23 is fixedly connected to the upper cover 21. A power socket 27 is provided on one side surface of the lower cover 26 and the upper cover 21. An air pipe 41 is installed on the inner surface of the vacuum pump 4. One end of the air pipe 41 is connected to the solenoid valve 24. The upper cover 21 is fixedly connected to the transparent vacuum chamber 1 by screws. A sealing ring 22 is provided at the connection between the transparent vacuum chamber 1 and the upper cover 21. The lower cover 26 and the lower box together form the base box 2, which can be disassembled and opened for easy installation and maintenance of the vacuum pump 4, the solenoid valve 24 and the vibrator 5. The sealing ring 22 is used to maintain the sealed connection between the transparent vacuum chamber 1 and the upper cover 21.

[0028] In this embodiment, the vibrator 5 is a 40kHz transducer, and the vibrator 5 is integrated on the stainless steel vibration panel 23. A pressure sensor 31 is installed on the back of the operation panel 3, and the other end of the air pipe 41 is connected to the pressure sensor 31. The vacuum pump 4 has a pumping rate of ≥15L, and the pressure sensor 31 has a monitoring range of -100kPa to 0kPa to monitor the internal pressure of the transparent vacuum chamber 1. Under the control of the vacuum pump 4 and the control circuit board, the vacuum pump 4 pumps air to -95kPa to initially expand the bubble volume; the ultrasonic pulse mode is started simultaneously, and the mode is turned off after 3 minutes of vibration to break up the remaining tiny bubbles; at the same time, the ultrasonic wave is started to heat the resin, which can accelerate the liquid flow. After the ultrasonic wave stops, the vacuum pump 4 continues to work to remove the remaining bubbles.

[0029] When using the device, vacuum pump 4 draws air to -95 kPa to initially expand the bubble volume; simultaneously, ultrasonic pulse mode is activated, vibrating for 3 minutes and then shut off to break up residual tiny bubbles; at the same time, ultrasonic waves are activated to heat the resin, which can accelerate the liquid flow. After the ultrasonic waves stop, vacuum pump 4 continues to work to remove remaining bubbles. By controlling the alternation of vacuum and ultrasonic operation through timing, energy interference is avoided, improving degassing efficiency by more than 30%, achieving a bubble removal rate of >95% for bubbles smaller than 0.05 mm, shortening the processing time to 10-20 minutes, supporting materials with a viscosity range of 100-10,000 cps, and compatible with laboratories and small production lines. The low-power vacuum pump 4 and intermittent ultrasonic operation mode reduce energy consumption by 40%.
