Description

Technical Field

[0001] The invention relates to the technical field of distillation devices, in particular to a chemical experiment distillation device. Background Art

[0002] Distillation is a thermodynamic separation process. It uses the different boiling points of components in a mixed liquid or liquid-solid system to evaporate the low-boiling-point component and then condense it to separate the entire component. It is a unit operation process that combines the two unit operations of evaporation and condensation. Compared with other separation methods, such as extraction, filtration and crystallization, it has the advantage of not requiring the use of solvents other than the system components, thereby ensuring that no new impurities are introduced. The liquid is first heated to boiling, then the liquid is converted into steam, and finally the steam is cooled and condensed into liquid. The combined operation of these two processes is called distillation. In chemical experiments, the commonly used distillation apparatus is generally composed of a distillation flask, a thermometer, a condenser, a liquid receiving tube and a receiving bottle.

The structural surface of one end of the two composite threaded rods 173 away from the second support frame 7 is provided with an external thread that can be threadedly connected with the limiting threaded hole. The limiting sleeve 171 is fixedly connected to the middle surface of the corresponding support curved rod 13, and the damping spring 174 is fixedly connected to the middle surface of the corresponding support curved rod 13. The damping block 172 is clamped in the interior of the limiting sleeve 171, and the other end of the composite threaded rod 173 passes through the limiting sleeve 171 and is fixedly connected to the end face corresponding to the damping block 172. The two ends of the buffer spring 174 are respectively fixedly connected to the surface of the limiting sleeve 171 and the inner wall of the corresponding structure of the second supporting frame 7. The two buffer top pressure assemblies 17 can cooperate with the two supporting curved rods 13 and the two hollow arc plates 8 to perform adaptive mechanical clamping of the convection tube 604, and the buffer top pressure assemblies 17 will also provide a damping effect during use to improve the stability of the two hollow arc plates 8.

[0052] Working principle: When in use, place the distillation flask 601 on the top of the heating tank 403, and the top side of the distillation flask 601 is fitted with the transition rod 301, then the flexible NdFeB magnet belt 304 is wrapped around the other side of the top of the distillation flask 601 and clamped inside the hollow clamp ring 302. When facing distillation flasks 601 of different specifications, the length of the flexible NdFeB magnet belt 304 and the hollow clamp ring 302 can be adjusted according to the actual situation until the hollow clamp ring 302 and the flexible NdFeB magnet belt 304 are both tightly attached to the surface of the distillation flask 601, and the existence of the buffer layer 305 can firmly fix the distillation flask 601 without damaging it.

[0053] For adjusting the experimental heating height of the distillation flask 601, the user can hold the handle 210 with one hand and rotate the rotating block 207 with the other hand, thereby rotating the screw rod 206 to engage the adjusting nut 211, and then the adjusting nut 211 drives the lifting rod 209 and the linkage rod 212 to adjust the height until the appropriate height is reached.

[0054] Next, for the liquid cooling catalysis and support of the flow tube 604, the dual-axis servo motor 14 can be started, and the output end of the dual-axis servo motor 14 drives the transmission gear 15 to synchronously mesh and drive the two compound spur plates 16, and then the two compound spur plates 16 drive the two hollow arc plates 8 to automatically clamp the flow tube 604 through their corresponding supporting curved rods 13. After completion, the stability of the flow tube 604 operation can be maintained, and the buffer top pressure component 17 that moves synchronously with the two hollow arc plates 8 can be used to damp the damping block 172, the composite threaded rod 173 and the buffer spring 174 inside the buffer top pressure component 17 after the flow tube 604 is subjected to vibration during subsequent use, so as to further improve the use stability of the flow tube 604, and then support the flow tube 604 and the condenser 605 in the entire distillation device so that it can maintain the angle of liquid circulation;

[0055] After the whole device is assembled, the heating wire 402 in the heating component 4 is turned on to heat the distillation flask 601. To ensure stability, during the experiment, the handle 210 can be held continuously to ensure the stability of the distillation flask 601 after lifting. As for the gaseous fluid in the flow tube 604 that is transported to the gaseous fluid in the flow tube 604 due to the heating of the substance in the distillation flask 601, the existing pumping equipment can be matched with the two hollow arc plates 8, the two second water inlet pipes 9, the two second water outlet pipes 10 and the transition square pipe 11, and then the gaseous fluid in the flow tube 604 is subjected to circulating cooling and liquid cooling treatment, and the liquid-cooled fluid will enter the liquid storage cup 608 through the flow tube 604 for centralized collection.

[0056] When the use environment cannot provide pumping conditions, the circulation cooling liquid cooling treatment of the gaseous fluid inside the convection tube 604 can be replaced by another method, that is, the output end of the dual-axis servo motor 14 drives the transmission gear 15 to synchronously mesh and drive the two compound straight tooth plates 16, and then the two compound straight tooth plates 16 drive the two hollow arc plates 8 through their corresponding supporting curved rods 13 to automatically clamp the convection tube 604, remove the screws between the compound straight tooth plates 16 and the supporting curved rods 13, and then, the material in the distillation flask 601 is transported to the flow tube 604 due to the heating. After the gaseous fluid inside, twist and remove the threaded plug 22 and open the internal valves of the two gas valve pipes 18, start the dual-axis servo motor 14 and make the dual-axis servo motor 14 reciprocate, and then use the output end on the other side of the dual-axis servo motor 14 to drive the fan blades 20 to rotate synchronously to deliver air, and the air inlet 21 provides an air inlet channel, and the airflow output by the fan blades 20 will enter the two hollow arc plates 8 through the two gas valve pipes 18, and the convection tube 604 will be air-cooled to meet the cooling and liquefaction requirements. The used air will be discharged through the two second water inlet pipes 9, and it can be reciprocated in this way.
