[0026] Please refer to Figures 1-4, the utility model provides a vacuum distillation furnace for refining high-tin alloy lead, which includes a distillation tank 1. One side of the top of the distillation tank 1 is fixedly communicated with a valve 2 that can be opened and closed. On both sides of the bottom of the inner wall of the distillation tank 1, heaters 6 are fixedly embedded to play a heating role. The other side of the top of the distillation tank 1 is fixedly connected with a steam pipe 7. One end of the steam pipe 7 is fixedly connected with a spiral pipe 9 to increase the flow area. The bottom end of the spiral pipe 9 is fixedly communicated with a collection tank 10. The surface of the spiral pipe 9 is fixedly connected with a cooling tank 8. The middle of the top of the distillation tank 1 is connected with a transmission box 13. The top end of the inner wall of the transmission box 13 is rotationally connected with an inner shaft 18 through a first bearing. The top end of the inner wall of the distillation tank 1 is rotationally connected with an outer shaft 16 through a second bearing. The bottom of the inner shaft 18 and the bottom of the outer shaft 16 are both fixedly connected with a number of stirring plates 20 to play a role in stirring and evenly heating. A liquid level sensor 5 is fixedly installed on the inner wall of the collection tank 10 to monitor the liquid level.

[0027] During use, the high-tin alloy lead raw material is put into the distillation tank 1, the valve 2 is closed, and the vacuum is pumped and the heater 6 is started for heating. After reaching a certain boiling point, the lead solution is converted into steam, enters the spiral pipe 9 through the steam pipe 7 for cooling, and forms a solution that falls into the collection tank 10. By arranging a liquid level sensor 5 on the inner wall of the collection tank 10, during the distillation and purification process, the liquid level of the purified liquid in the collection tank 10 will always be in an ascending state. When it is monitored that the liquid level stops rising, the machine can be shut down to complete the distillation, avoiding waste of resources;

[0028] On one side of the transmission box 13 close to the steam pipe 7, a motor 14 is fixedly installed. The output end of the motor 14 passes through the inner wall of the transmission box 13 and is fixedly connected with a first bevel gear 15. The top end of the outer shaft 16 passes through the distillation tank 1 and is fixedly sleeved with a second bevel gear 17. The top end of the inner shaft 18 is fixedly sleeved with a third bevel gear 19. The bottom of the first bevel gear 15 is in transmission connection with the second bevel gear 17, and the top of the first bevel gear 15 is in transmission connection with the third bevel gear 19 to play a role in transmission. The output end of the motor 14 is rotationally connected with the inner wall of the transmission box 13 through a third bearing to improve the rotation stability;

[0029] During use, by starting the motor 14 to drive the first bevel gear 15 to rotate, and then driving the outer shaft 16 and the inner shaft 18 to rotate respectively through the second bevel gear 17 and the third bevel gear 19, and the rotation directions of the outer shaft 16 and the inner shaft 18 are opposite. Therefore, the stirring plates 20 at the upper and lower parts in the distillation tank 1 will rotate in opposite directions, making the heating of the high-tin alloy lead liquid more uniform and ensuring the purity after distillation;

[0030] The top end of the valve 2 is fixedly connected with a feed nozzle 3 for feeding materials. The top of the cooling tank 8 is fixedly communicated with a cold water inlet 11, and the bottom of the cooling tank 8 is fixedly communicated with a cold water outlet 12 for the circulation of the cooling liquid.

[0031] During use, high-tin alloy lead material is put into the distillation tank 1 from the feed nozzle 3. After closing the valve 2, the vacuum pump 4 is started to evacuate the tank, and then the distillation operation is carried out. The coolant is input from the cold water inlet 11 of the cooling tank 8 and discharged from the cold water outlet 12 for circulation, which can cool down the steam in the spiral tube 9 and condense it into liquid.

[0032] A deflector plate 22 is fixedly connected to the bottom end of the inner wall of the distillation tank 1 to play a guiding role. The middle part of the bottom end of the distillation tank 1 is fixedly communicated with a sewage flange 23. A flange cover 24 is fixedly installed at the bottom end of the sewage flange 23 through bolts to play a sealing role.

A scraper 25 is fixedly connected to the middle part of the outer shaft 16 to play a cleaning role.

[0033] During use, after the distillation is completed, the flange cover 24 can be removed. The residual materials in the distillation tank 1 are discharged from the sewage flange 23 under the action of the deflector plate 22, and the scraper 25 can be driven to rotate to scrape off the residual materials adhered to the inner side wall of the distillation tank 1, making the cleaning more thorough. The provided brackets 21 are used to support the distillation tank 1 for convenient discharging of materials.

[0034] Specifically in use, the vacuum distillation furnace of the present utility model for refining high-tin alloy lead puts the high-tin alloy lead raw material into the distillation tank 1, closes the valve 2, evacuates the vacuum through the vacuum pump 4, and starts the heater 6 for heating. The motor 14 is started to drive the bevel gear one 15 to rotate, and then the outer shaft 16 and the inner shaft 18 are driven to rotate respectively through the bevel gear two 17 and the bevel gear three 19, and the rotation directions of the outer shaft 16 and the inner shaft 18 are opposite. Therefore, the stirring plates 20 at the upper and lower parts in the distillation tank 1 will rotate in opposite directions, making the heating of the high-tin alloy lead liquid more uniform, ensuring the purity after distillation. The coolant is input into the cooling tank 8. After reaching a certain boiling point, the lead solution is converted into steam, enters the spiral tube 9 through the steam pipe 7 for cooling, and forms a solution that falls into the collection tank 10. A liquid level sensor 5 is arranged on the inner wall of the collection tank 10. During the distillation and purification process, the liquid level of the purified liquid in the collection tank 10 will always be in an ascending state. When it is monitored that the liquid level stops rising, the machine can be shut down to complete the distillation, avoiding waste of resources.
