[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] See also Figure 1 As shown, this embodiment provides a rapid degassing device for electrolyte of a liquid injection machine, comprising:

[0030] A cache tank 1, wherein the cache tank 1 is provided with a cache chamber for caching electrolyte;

[0031] A partition 2, wherein the partition 2 is arranged in the cache tank to separate the cache chamber into an electrolyte cache compartment and a bubble removal compartment, and the tops of the two compartments are interconnected, wherein the cache compartment is connected to a liquid inlet pipe 5 located at the bottom thereof, and the bubble removal compartment is connected to a liquid outlet pipe 6 located at the bottom thereof;

[0032] A pressure relief plate 3, wherein the pressure relief plate 3 is arranged in the debubble compartment and is arranged to be inclined downward with respect to the partition plate 2;

[0033] An ultrasonic component 4 is disposed at the top of the buffer tank 1 , and an output end of the ultrasonic component 4 extends into the debubble compartment to perform ultrasonic debubble removal.

[0034] Specifically, in the present embodiment, the electrolyte buffer tank 1 is relatively small in size and is designed with two compartments, namely, a buffer compartment and a bubble removal compartment. The buffer compartment can preliminarily buffer the electrolyte entering the buffer compartment from the liquid inlet pipe 5. The electrolyte buffered to a certain volume flows from the top of the buffer compartment to the bubble removal compartment, and flows slowly through the inclined pressure relief plate 3, thereby reducing the generation of impact bubbles; at the same time, in conjunction with the ultrasonic component 4 provided on the buffer tank 1, ultrasonic vibration is used to generate energy to quickly rupture the bubbles, thereby achieving the purpose of quickly removing bubbles.

[0035] The cache tank of a rapid debubbling device for electrolyte in a liquid injection machine described in this embodiment is relatively small in size, which effectively reduces the floor space occupied; the cache tank 1 is divided into a cache compartment and a debubbling compartment which are interconnected at the top by setting a partition 2, and the rapid debubbling function is realized by using the set pressure relief plate 3 and ultrasonic component 4, which effectively improves the liquid injection efficiency and the liquid injection stability.

[0043] With the pressure relief plate 3 arranged in the bubble removal compartment, bubbles can be quickly removed and the liquid injection efficiency is high, reducing the original bubble removal time from more than 5 minutes to less than 1 minute.

[0044] In some embodiments, an upper liquid level sensor 10 and a lower liquid level sensor 11 are respectively installed on the outer wall of the cache tank 1;

[0047] The temperature controller 8 detects the temperature of the liquid in the tank and feeds it back to the ultrasonic device 41 to control the amplitude; the pressure gauge 9 detects the internal pressure of the buffer tank and discharges the gas in the tank in real time by detecting the pressure in the tank.
