[0026] Please see the appendix Figure 2 A gas-liquid separation device with an anti-clogging device includes a gas-liquid separator 4 and an anti-clogging device 5. The anti-clogging device 5 is disposed inside the gas-liquid separator 4 and covers the drain port 8 of the gas-liquid separator 4. The anti-clogging device 5 has a drain filter perforation for liquid flow, so that the gas-liquid separator 4, the drain filter perforation and the drain port 8 form a drain path, and the size of the drain filter perforation is smaller than the size of solid foreign objects inside the gas-liquid separator 4.
[0027] By the arrangement of the anti-blocking device 5, in the process of discharging the liquid from the liquid discharge port 8 of the gas-liquid separator 4, the graphite fragments and silicon dioxide powder in the liquid are intercepted in the gas-liquid separator 4 through the liquid discharge filtering hollow, and the liquid is discharged after flowing out to the liquid discharge port 8, thereby avoiding the problem of blocking the liquid discharge port 8, preventing the blocking in advance, and ensuring the continuous operation of the gas-liquid separator 4.
[0028] Please refer to the accompanying drawings Figure 3 The anti-blocking device 5 comprises a top plate 9 and a plurality of support columns 10, the upper ends of the support columns 10 are connected to the top plate 9, and the lower ends of the support columns 10 are connected to the inner wall of the gas-liquid separator 4; the plurality of support columns 10 are arranged at intervals along the circumference of the top plate 9 and surround the liquid discharge port 8, so that the top plate 9 covers directly above the liquid discharge port 8, and the liquid discharge filtering hollow is formed between adjacent support columns 10 and the top plate 9.
[0029] Through the arrangement of the top plate 9 and the support columns 10, the solid foreign matters can be effectively blocked, and the liquid mixed with the solid foreign matters is prevented from flowing directly into the liquid discharge port 8, thereby preventing the liquid discharge port 8 from being blocked.
[0030] Preferably, the top plate 9 can adopt but is not limited to a flat plate structure, and the support columns 10 can adopt but are not limited to a cylindrical structure, and the shape and size of the top plate 9 and the support columns 10 can be adaptively adjusted according to actual use requirements. The arrangement interval of adjacent support columns 10 is adaptively adjusted according to the size of the graphite fragments, silicon dioxide powder and other solid foreign matters to be intercepted, so as to ensure the effective separation of the liquid and the solid foreign matters and achieve the purpose of preventing blocking.
[0031] Please refer to the accompanying drawings Figure 4 The lower part of the plurality of support columns 10 is provided with a flow-through baffle, the flow-through baffle and the top plate 9 and the plurality of support columns 10 form an upper opening 11 therebetween; the flow-through baffle circumferentially surrounds the liquid discharge port 8, and a plurality of lower openings 12 are formed in the flow-through baffle, and the upper opening 11 and the lower opening 12 constitute the liquid discharge filtering hollow.
[0032] Preferably, the lower opening 12 can be provided as a circular hole, and the size of the circular hole is smaller than the arrangement interval of adjacent support columns 10, thereby further improving the filtering effect, ensuring the separation effect of smaller size solid foreign matters, and ensuring the smoothness of the liquid discharge port 8, and avoiding the risk of parking caused by sudden blocking.
[0033] There is no special provision for the size and number of the upper opening 11 and the lower opening 12, and it is appropriate that the liquid can be efficiently discharged and the solid foreign matters are intercepted in the gas-liquid separator 4.
[0034] The total area sum B of the plurality of lower openings 12 is greater than the cross-sectional area A of the liquid discharge port 8, that is, B / A>1.
[0035] In order to ensure that the liquid can be efficiently discharged from the liquid discharge port 8, the total area B of the plurality of lower openings 12 should be greater than the cross-sectional area A of the liquid discharge port 8, so as to avoid affecting the discharge efficiency of the liquid due to filtering of solid foreign matters, and therefore the size, shape and number of the upper openings 11 and the lower openings 12 can be flexibly adjusted according to actual use requirements under the condition of B / A>1.

Figure 6
[0040] By arranging the vertical plate 15, the residual liquid droplets in the gas can be better separated. The gap between the vertical plate 15 and the top plate 9 can ensure the passage of the gas.
