Description

Technical Field

[0001] The utility model relates to a novel vacuum defoaming device. Background Art

[0002] In the field of lithium battery production, the equipment in the front-end production workshop includes mixers, transfer tanks, coaters, etc. The coating process is particularly important because the quality of the electrode coating directly determines the quality of the manufactured battery cell and affects the various performance indicators of the lithium battery. Due to the diversity of coating slurry formulas, the coating parameter settings and the final coating effects are also different. At present, the slurry formula has not achieved the ideal effect during coating. The reason is that the slurry formula produces a trace amount of hydrogen gas in the storage tank, which causes a large number of tiny bubbles in the slurry, thus affecting the coating effect. The mature degassing machines on the market are generally large in size and deal with general gas bubbles. There is no ready-made equipment that can be used in the narrow space on site and can handle the flammable and explosive hydrogen bubbles. At the same time, the vacuum pumps configured in the existing vacuum degassing devices are generally ordinary rotary vane vacuum pumps and ordinary vacuum filters. Although rotary vane vacuum pumps have the advantages of high vacuum degree and low price, rotary vane vacuum pumps need to be used with tight Sealing oil is used for liquid sealing to achieve a higher vacuum degree, and all manufacturing-related equipment in the lithium battery industry strictly prohibits copper, zinc and oil. Therefore, the sealing oil of the rotary vane vacuum pump may be at risk of contaminating the slurry; and the removed bubbles contain flammable and explosive hydrogen, which will be sucked into the vacuum pump and come into contact with the sealing oil, which increases the unsafe factor. In addition, when removing bubbles, the vacuum pump will inhale some vaporized slurry, which will enter the pump body and come into contact with the sealing oil to become a slurry solution. The mixture of slurry solution and sealing oil will contaminate the sealing oil and make it viscous, which will not only reduce the sealing effect of the rotary vane vacuum pump but also corrode the pump body, causing the rotary vane vacuum pump to be damaged quickly, thereby reducing the vacuum degree and failing to achieve the defoaming effect.

[0028] In the present embodiment, the vacuum debubbling tank comprises a debubbling tank body 111, the tank body opening at the upper part of the debubbling tank body is closed by a debubbling tank cover 112, a debubbling turntable 113 is rotatably connected to the middle part of the debubbling tank body, a feed hole is opened on the vacuum debubbling tank, the feed hole is connected to an external material source via a feed pipe 117 with a switch valve, the output end of the feed pipe extends into the vacuum debubbling tank through the feed hole and is located above the debubbling turntable, the debubbling tank body and the debubbling tank cover are locked by plum screws to form a closed container.

[0030] In this embodiment, a discharge port is provided at the lower part of the debubble tank body, and the discharge port is connected to the external coating buffer tank through a discharge pipe 118 with a screw pump 12. The vacuum debubble tank is installed with a debubble tank level gauge 1110, a debubble tank hydrogen concentration detection instrument 1111, and a debubble tank vacuum detection instrument 1112.
