[0018] Embodiment 1:

[0019] Such as Figure 1-2As shown in the figure, the utility model provides a medium oil filtering and defoaming device for a hydraulic device, which includes an oil tank 1, a mounting seat 2 and mounting screws 3. An oil inlet hole 4 is arranged inside the mounting seat 2. A connecting shell 5 is fixedly connected to the lower surface of the mounting seat 2. A filtering hole 6 is arranged at the bottom of the connecting shell 5. A connecting ring 7 is fixedly connected to the lower surface of the connecting shell 5. A filter element 8 is threadedly connected to the inner surface of the connecting ring 7. An ultrasonic generator 9 and a protective shell 10 are fixedly connected to the bottom of the inner surface of the oil tank 1. A transducer 11 is arranged on the upper surface of the ultrasonic generator 9. An ultrasonic vibrator 12 is arranged on the upper surface of the transducer 11. An oil outlet pipe 14 is fixedly connected to the outer surface of the oil tank 1.

[0020] Specifically, the mounting seat 2 is connected to the oil tank 1 through the mounting screws 3.

[0021] Specifically, the oil inlet hole 4 is arranged directly above the filtering hole 6, and the filter element 8 is arranged directly below the filtering hole 6.

[0022] Specifically, the ultrasonic generator 9 and the transducer 11 are arranged inside the cavity of the protective shell 10.

[0023] Specifically, a sealing ring 13 is arranged at the top of the protective shell 10, and the outer surface of the ultrasonic vibrator 12 is sleeved inside the sealing ring 13.

[0024] Specifically, a cleaning pipe 15 is fixedly connected to the bottom of the oil tank 1, and a sealing cover 16 is arranged at the bottom of the cleaning pipe 15.

[0025] The working principle and beneficial effects of the above embodiments.

[0026] During use, the hydraulic oil enters from the oil inlet hole 4 and passes through the filtering hole 6 at the bottom of the connecting shell 5. Larger impurities in the hydraulic oil are filtered out by the filtering hole 6 to achieve preliminary filtration. Then the hydraulic oil enters the filter element 8 to filter out tiny particles and impurities in the hydraulic oil to achieve secondary filtration. The ultrasonic generator 9 generates high-frequency vibration signals, which are converted into ultrasonic energy through the transducer 11 and transmitted to the ultrasonic vibrator 12. The ultrasonic vibrator 12 generates high-frequency vibration in the hydraulic oil, thereby destroying the bubble structure and removing bubbles. At the same time, the ultrasonic wave can also promote the aggregation and precipitation of tiny particles and impurities in the hydraulic oil. By opening the sealing cover 16, the precipitated impurities in the oil tank 1 are discharged from the cleaning pipe 15, which is convenient for maintaining the oil tank 1. By removing the mounting screws 3, the whole composed of the mounting seat 2, the connecting shell 5, the connecting ring 7 and the filter element 8 is taken out from the oil tank 1, and then the filter element 8 is removed from the connecting ring 7 to facilitate cleaning the accumulated impurities in the connecting shell 5 and replacing the new filter element 8. Among them, the oil tank 1 not only stores the hydraulic oil, but also plays a role in heat dissipation and sedimentation of impurities.
