[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0028] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6A multi-stage filtration-type condensation collection device includes a frame 1, and further includes a condensation device 2, a conveying device 3, and a filtering device 4. The condensation device 2 is installed on the left side of the frame 1, the conveying device 3 is installed below the condensation device 2, and the filtering device 4 is installed below the conveying device 3. The condensation device 2 includes an outer shell 21, an outer condensation pipe 22, a first discharge port 23, a middle shell 24, and a right-side inlet port 25. The outer shell 21 is fixedly installed on the left side of the frame 1, and an air inlet 26 is fixedly installed on the left side of the outer shell 21. The outer condensation pipe 22 is fixedly installed inside the outer shell 21, and the input end of the outer condensation pipe 22 penetrates through the outer shell 21 and is fixedly installed on the left side of the outer shell 21. The first discharge port 23 is fixedly installed below the outer shell 21. The middle shell 24 is fixedly installed inside the outer shell 21, and the right-side inlet port 25 is fixedly installed on the right side of the middle shell 24. A second discharge port 27 is installed on the lower side of the middle shell 24. The condensation device 2 also includes a dual circulation mechanism installed inside the middle shell 24.

[0029] The condenser 2 introduces liquid nitrogen to condense the mixed gas, producing germanium tetrafluoride liquid. The conveying device 3 conveys the germanium tetrafluoride liquid to the filtration device 4, and the filtration device 4 filters the germanium tetrafluoride liquid.

[0030] The input end of the outer condenser pipe 22 of the condenser device 2 is connected to the external liquid nitrogen conveying device. Liquid nitrogen enters from the input end of the outer condenser pipe 22, which lowers the temperature in the space formed by the outer shell 21 and the middle shell 24. The mixed gas enters the space formed by the outer shell 21 and the middle shell 24 through the air inlet 26 on the left side of the outer shell 21. The mixed gas is cooled for the first time. After the germanium tetrafluoride is condensed, it forms germanium tetrafluoride liquid, which accumulates on the lower side of the outer shell 21 and is transported away through the first discharge port 23 on the lower side of the outer shell 21.

[0031] The dual-circulation mechanism performs secondary and tertiary cooling and condensation on the mixed gas that has been cooled in the first cooling stage.

[0032] The dual circulation mechanism includes an inner shell 28, a third discharge port 29, a middle condenser pipe 210, and a left input port 211. The inner shell 28 is fixedly installed inside the outer shell 21. The third discharge port 29 is fixedly installed on the lower side of the inner shell 28. The middle condenser pipe 210 is fixedly installed inside the middle shell 24. The left input port 211 is fixedly installed on the left side of the inner shell 28. The input end of the middle condenser pipe 210 is fixedly connected to the output end of the outer condenser pipe 22.

[0033] Liquid nitrogen enters the middle condenser 210 of the dual circulation mechanism from the outer condenser 22. The liquid nitrogen in the middle condenser 210 lowers the temperature in the space formed by the inner shell 28 and the middle shell 24. The mixed gas that has been cooled for the first time is cooled for the second time, which further condenses the germanium tetrafluoride in the mixed gas, forming germanium tetrafluoride liquid that accumulates on the lower side of the middle shell 24 and is transported away through the second outlet 27 on the lower side of the middle shell 24.

[0034] The dual circulation mechanism further includes an inner condenser 212 and a connecting pipe 213. The inner condenser 212 is fixedly installed inside the inner shell 28. One end of the connecting pipe 213 passes through the outer shell 21 and the middle shell 24 and is fixedly connected to the inner shell 28. The input end of the inner condenser 212 is fixedly connected to the output end of the middle condenser 210. The output end of the inner condenser 212 passes through the outer shell 21 and is fixedly installed on the upper side of the outer shell 21.

[0035] The mixed gas, which has been condensed by secondary cooling, enters the inner shell 28 through the left inlet 211. Liquid nitrogen in the middle condenser 210 flows into the inner condenser 212 and exits from the upper outlet of the inner condenser 212. The liquid nitrogen in the inner condenser 212 lowers the temperature inside the inner shell 28. The mixed gas, which has been cooled a second time, is cooled a third time, further condensing the remaining germanium tetrafluoride in the mixed gas into liquid, which is then transported away from the third outlet 29 on the lower side of the inner shell 28. The middle shell 24 is located inside the outer shell 21, and the inner shell 28 is located inside the middle shell 24, so that the temperature gradually decreases from the outside to the inside. This allows the mixed gas to undergo multiple condensations with decreasing temperatures, improving the condensation effect of germanium tetrafluoride. At the same time, the size of the equipment is smaller than that of traditional multi-stage condensation equipment, reducing the space occupied by the equipment.

The middle connecting pipe 32 passes through the outer connecting pipe 31 and is fixedly installed on the outer connecting pipe 34. 1. The inner connecting pipe 33 is fixedly installed on the middle connecting pipe 32 through the middle connecting pipe 32.

Valves 410 are provided on the outer connecting pipe 31, the middle connecting pipe 32 and the inner connecting pipe 33 for opening and closing the outer connecting pipe 31, the middle connecting pipe 32 and the inner connecting pipe 33.

[0037] Open the valves 410 on the outer connecting pipe 31, the middle connecting pipe 32, and the inner connecting pipe 33, and the germanium tetrafluoride liquid flows from the outer connecting pipe 31, the middle connecting pipe 32, and the inner connecting pipe 33 towards the irregular support 34.

[0038] The filtration device 4 includes: a rotating frame 41, vertical tubes 42, a connecting disc 43, and filter screens 44. The rotating frame 41 is rotatably connected to the frame 1.

The outer connecting tube 31, the middle connecting tube 32, and the inner connecting tube 33 correspond one-to-one with the non-adjacent vertical tubes 42. Multiple filter screens 44 are snapped onto the upper side of the vertical tubes 42.

[0039] The filter device 4 further includes a drive mechanism, which is mounted on the rotating frame 41. The drive mechanism includes a guide post 45 and an electric telescopic rod 46.

One end of the two electric telescopic rods 46 is fixedly mounted on the rotating frame 41, and the end of the electric telescopic rod 46 away from the rotating frame 41 is fixedly connected to the connecting disc 43.

[0040] Germanium tetrafluoride liquid flows from the outer connecting pipe 31, the middle connecting pipe 32, and the inner connecting pipe 33 towards the irregular support 34, and from the irregular support 34 to the filter screen 44. After being filtered by the filter screen 44, it flows down from the vertical pipe 42.

[0041] The driving mechanism further includes a rotating assembly, which is mounted on the rotating frame 41. The rotating assembly includes a toggle lever 47 and two limit seats 48. The toggle lever 47 is hinged to the rotating frame 41, and the two limit seats 48 are fixedly mounted on the frame 1.

[0042] To replace filter 44, shorten the output end of the electric telescopic rod 46 to move the connecting disc 43 downward. The guide post 45 is used to limit the vertical movement of the connecting disc 43. Place the three filter screens 44 on the remaining vertical tube 42 respectively. Rotate the lever 47 to move it away from one of the limiting seats 48. Rotate the rotating frame 41 through the lever 47 to move the lever 47 to the other limiting seat 48. Rotate the lever 47 to lock it onto the limiting seat 48. At this time, the rotating frame 41 rotates 60 degrees to remove the three old filter screens 44. Return the output end of the electric telescopic rod 46 to its original position. The filter screen replacement is now complete, which facilitates quick filter screen replacement.
