The interior of the second condenser tube 9 is connected with the interior of the first condenser tube 8. A fixed plate 10 is fixedly connected to the support plate 2, and the fixed plate 10 is placed in parallel with the circular end surface of the condenser tube 6. A rotating motor 11 is provided on any fixed plate 10, and the rotating motor 11 is fixedly connected to a side of the fixed plate 10 close to the condenser tube 6. A rotating shaft 111 is provided at the output end of the rotating motor 11, and a small gear 12 is sleeved on the rotating shaft 111. The rotating shaft 111 can drive the small gear 12 to rotate, and a large gear 13 is sleeved on the shaft tube 5 on the same side as the small gear 12. The large gear 13 is fixedly connected to the side surface of the shaft tube 5, and the small gear 12 and the large gear 13 are connected by a belt 14;

[0032] Open the condensation valve 71, and let the condensation gas into the condensation tube 6, open the switch valve 41 on any one of the inlet pipes 4, and turn on the air pump 3 connected to the inlet pipe 4, the air pump 3 introduces the high-temperature aluminum fluoride gas into the first condensation tube 8 and the second condensation tube 9, and at the same time turn on the rotating motor 11, the output end of the rotating motor 11 drives the rotating shaft 111, the rotating shaft 111 drives the small gear 12, the small gear 12 drives the belt 14, the belt 14 drives the large gear 13, the large gear 13 drives the shaft tube 5, the shaft tube 5 drives the first condensation tube 8, and the first condensation tube 8 drives the second condensation tube 9 to rotate; the high-temperature fluoride The aluminum gas in the first condenser tube 8 and the second condenser tube 9 is cooled by the condensation of the condensation gas in the condensation tube 6, and the aluminum fluoride gas condenses and crystallizes into aluminum fluoride crystals on the inner walls of the first condenser tube 8 and the second condenser tube 9. At the same time, the rotation of the second condenser tube 9 allows the high-temperature condensation gas formed after the superheat exchange with the high-temperature aluminum fluoride gas to diffuse rapidly, preventing the high-temperature condensation gas from gathering on the outer tube walls of the first condenser tube 8 and the second condenser tube 9, so that the low-temperature condensation gas in the condensation tube 6 can continue to condense, thereby achieving full condensation of the high-temperature aluminum fluoride gas and improving the condensation work efficiency.

[0033] In order to achieve the automatic and continuous discharge of aluminum fluoride crystals condensed in the first condenser tube 8 and prevent the crystals from gathering at one end of the first condenser tube 8 and causing blockage, the first condenser tube 8 is provided with through-hole grooves 82 on the peripheral side surfaces near both ends. The through-hole grooves 82 pass through the upper and lower peripheral sides of the first condenser tube 8. A cylindrical pushing block 83 is provided in the first condenser tube 8. The peripheral wall of the pushing block 83 is in contact with the inner wall of the first condenser tube 8. The length of the pushing block 83 is greater than the length of the through-hole groove 82. The pushing block 83 can seal and block the through-hole groove 82.

[0034] Working principle: First, the first air intake is carried out, the air pump 3 on either side is turned on, the switch valve 41 is opened, and high-temperature aluminum fluoride gas is introduced from one end of the first condenser tube 8. Under the action of gas pressure, the high-temperature aluminum fluoride gas pushes the push block 83 to move along the first condenser tube 8, and the push block 83 slides to the end of the first condenser tube 8 away from the air intake, and then condensation and crystallization are carried out; after the first air intake is fully condensed, the second air intake is carried out, and the air pump 3 on the other side is turned on to introduce high-temperature aluminum fluoride gas into the first condenser tube 8. The gas pushes the push block 83 to move toward the first air intake end. During the movement, the push block 83 drives the crystals produced after the first air intake condensation to move, and discharges the crystals from the through-hole groove 82 near the first air intake end. While the crystals are discharged, the push block 83 also covers the through-hole groove 82 on this side, sealing and blocking the through-hole groove 82; after the second air intake is fully condensed, the air pump 3 at the first air intake end is turned on again, and the third air intake is carried out, and a similar process as the second air intake is carried out. The above process is repeated, and this process is repeated to achieve the automatic and continuous discharge of the aluminum fluoride crystals condensed in the first condensation tube 8, while preventing the crystals from gathering at one end of the first condensation tube 8 to cause blockage.

[0035] In order to realize the automatic discharge of the crystals generated by condensation and crystallization in the second condenser tube 9, a circular plate 91 is provided in each second condenser tube 9 connected to the upper and lower side walls of the first condenser tube 8. The circular plates 91 are placed coaxially with the second condenser tube 9, and the side surfaces of the circular plates 91 are in contact with the inner walls of the second condenser tube 9. The circular plates 91 in the two coaxially placed second condenser tubes 9 are fixedly connected by elastic rubber ropes 92, and the rubber ropes 92 are always in a stretched state; the rotating motor 11 is turned on, and the output end of the rotating motor 11 drives the rotating shaft 111, the rotating shaft 111 drives the small gear 12, the small gear 12 drives the belt 14, the belt 14 drives the large gear 13, the large gear 13 drives the shaft tube 5, the shaft tube 5 drives the first condenser tube 8, and the first condenser tube 8 drives the second condenser tube 9 to rotate. When the rotation speed is high, the centrifugal force generated is greater than the elastic force of the rubber rope 92. Under the action of the centrifugal force, the circular plate 91 moves along the second condenser tube 9 to the end away from the rotation center axis. After sufficient condensation, the rotating motor 11 is turned off, and the second condenser tube 9 starts to rotate slowly until it stops. When the rotation speed of the second condenser tube 9 decreases and the centrifugal force generated is insufficient, the circular plates 91 approach each other under the pull of the elastic force of the rubber rope 92. While the circular plates 91 approach each other, the circular plates 91 scrape the crystallized crystals on the wall of the second condenser tube 9. Driven by the circular plates 91, the crystals move along the second condenser tube 9, and finally the crystals generated in the second condenser tube 9 enter the first condenser tube 8 for easy discharge, thereby achieving the purpose of automatic discharge of the crystals generated by condensation and crystallization in the second condenser tube 9.

[0036] In order to prevent the two coaxial circular plates 91 from entering the same second condenser tube 9, which would result in the inability to effectively discharge the crystals in the second condenser tube 9, a fixedly connected positioning pin 93 is provided at one end of the second condenser tube 9 close to the peripheral wall of the first condenser tube 8, thereby preventing the two coaxial circular plates 91 from entering the same second condenser tube 9.

[0037] In order to prevent the high-temperature aluminum fluoride gas from entering the condenser tube 6 from the through-hole groove 82 at the air inlet end during air intake, and at the same time not hindering the discharge of crystals, two slidable annular sleeves 15 are provided on the tube wall near the two ends of the first condenser tube 8. The length of the annular sleeve 15 is greater than the length of the through-hole groove 82. The annular sleeve 15 can seal and block the through-hole groove 82. A connecting rod 16 is fixedly connected to the annular sleeve 15. The other end of the connecting rod 16 is fixedly connected to the first magnet piece 17. The first magnet piece 17 is fitted with the inner wall of the condenser tube 6. The two first magnet pieces 17 are fixedly connected by a first guide rod 18. The length of the first guide rod 18 is less than the length of the two through-hole grooves. 82, the rotating shaft 111 is connected to a threaded rod 19, the rotating shaft 111 can drive the threaded rod 19 to rotate, the other end of the threaded rod 19 passes through the fixed plate 10, the threaded rod 19 is rotatably connected to the fixed plate 10, the threaded rod 19 is provided with two sliders 20, the sliders 20 are provided with threaded holes, the threaded rod 19 passes through the threaded holes, the threaded rod 19 and the sliders 20 can be threadedly engaged with each other, the sliders 20 are fixedly connected to the second magnet piece 21, the second magnet piece 21 is in contact with the outer wall of the condensing cylinder 6, the position of the second magnet piece 21 corresponds to the first magnet piece 17, and a second guide rod 22 is fixedly connected between the two second magnet pieces 21;

[0038] When air is taken in from either end, the pushing block 83 moves away from the through hole groove 82 at that end under the action of gas pressure. At the same time, the rotating motor 11 is turned on, and the output end of the rotating motor 11 drives the rotating shaft 111, and the rotating shaft 111 drives the threaded rod 19 to rotate. The threaded rod 19 and the slider 20 are threadedly engaged and transmitted. The slider 20 drives the second magnet piece 21. Under the action of magnetic force, the second magnet piece 21 drives the first magnet piece 17, and the first magnet piece 17 drives the connecting rod 16. The connecting rod 16 drives the annular sleeve 15. The annular sleeve 15 moves toward the air inlet end to seal and block the through hole groove 82 near the air inlet end. At the same time, since the length of the first guide rod 18 is less than the distance between the two through hole grooves 82, the through hole groove 82 on the other side will be in an open state, thereby preventing the high-temperature aluminum fluoride gas from entering the condensation tube 6 from the through hole groove 82 at the air inlet end when air is taken in, and at the same time does not hinder the discharge of crystals.

[0039] In order to enable the rotating shaft 111 to selectively drive the pinion 12 and the threaded rod 19, a groove is provided on the circumferential side wall of the rotating shaft 111, and an automatic telescopic block 1111 is fixedly connected in the groove. A connecting block 23 is provided between the threaded rod 19 and the rotating shaft 111, and the connecting block 23 is fixedly connected to the rotating shaft 111. A circular hole seat is provided on the connecting block 23, and a rolling bearing 24 is provided in the circular hole seat. The outer ring of the rolling bearing 24 is fixedly connected to the circumferential side of the circular hole seat, and the threaded rod 19 is fixedly connected to the inner ring of the rolling bearing 24. A fixedly connected circular ring plate 25 is provided at the position of the threaded rod 19 near the rolling bearing 24, and a pair of symmetrically distributed first telescopic cylinders 26 are provided on the circular ring plate 25. The bottom of the first telescopic cylinder 26 is fixedly connected to the circular ring plate 25, and the telescopic rod of the first telescopic cylinder 26 is fixedly connected to the circular block 27. The circular block 27 can be inserted between the inner ring and the outer ring of the rolling bearing 24 to connect the inner ring of the rolling bearing 24 with the outer ring. The outer ring is engaged and connected; when only the rotating shaft 111 needs to drive the pinion 12, the automatic telescopic block 1111 is extended, so that the rotating shaft 111 is engaged with the pinion 12, and the first telescopic cylinder 26 is turned on at the same time. The telescopic rod of the first telescopic cylinder 26 contracts and drives the annular block 27 away from the rolling bearing 24, and the inner and outer rings of the rolling bearing 24 can rotate freely. At this time, rotating the rotating shaft 111 will only drive the pinion 12 to work; when only the rotating shaft 111 needs to drive the threaded rod 19 to rotate, the first telescopic cylinder 26 is turned on, and the telescopic rod of the first telescopic cylinder 26 is extended to drive the annular block 27 close to the rolling bearing 24, so that the annular block 27 engages the inner and outer rings of the rolling bearing 24 for synchronous movement, and at the same time, the automatic telescopic block 1111 is retracted. At this time, rotating the rotating shaft 111 only drives the threaded rod 19 to rotate, thereby achieving the purpose of the rotating shaft 111 selectively driving the pinion 12 and the threaded rod 19.

[0040] In order to facilitate the collection and storage of the discharged aluminum fluoride crystals, two discharge ports 61 are provided on the side wall of the lower end of the condensation cylinder 6. The position of the discharge port 61 corresponds to the position of the through-hole groove 82 at both ends of the first condensation tube 8.

The bottom of the second telescopic cylinder 28 is fixedly connected to the support plate 2, and the telescopic rod of the second telescopic cylinder 28 is fixedly connected to the discharge baffle 29. A storage groove 30 is provided on the support platform 1; when the aluminum fluoride crystals are discharged from the through-hole groove 82 on one side, the second telescopic cylinder 28 corresponding to the side is opened, and the telescopic rod of the second telescopic cylinder 28 contracts to drive the discharge baffle 29 away from the discharge port 61, so that the discharge port 61 is opened, and the aluminum fluoride crystals discharged from the through-hole groove 82 fall into the storage groove 30 through the discharge port 61, thereby achieving the purpose of conveniently collecting and storing the discharged aluminum fluoride crystals.
