[0030] Specifically, vertical plate 14 is located between vertical plate 213 and vertical plate 34, and vertical plate 14, vertical plate 213 and vertical plate 34 are located on three adjacent surfaces.

[0036] The temperature adjusting mechanism further comprises a driving gear 14, the driving gear 14 is fixedly installed on the third sliding block 12, the third sliding block 12 is slidably installed on the second vertical plate 13, and the third sliding block 12 is rotationally installed on one end of a push rod 11, the other end of the push rod 11 is slidably matched with the meandering groove 10 on the second rotating rod 9, the second rotating rod 9 is rotationally installed on the first vertical plate 4, the meandering grooves 10 are arranged at both ends of the second rotating rod 9, and the meandering groove 10 arranged at the end of the second rotating rod 9 away from the driving gear 14 is connected with the rotating mechanism.

[0037] The distillation barrel 2 is fixedly installed with a connecting column 15, the connecting column 15 is slidably matched with the meandering groove 10 on the end of the second rotating rod 9 close to the driving gear 14.

[0038] The liquid outlet mechanism comprises three reversing gears 28 arranged linearly, the reversing gears 28 are rotationally installed on the third vertical plate 34 through a central shaft, the central shaft is provided with a coil spring 30 between the third vertical plate 34; the reversing gears 28 are fixedly installed with a collecting box 27, the collecting box 27 is connected with a liquid inlet pipe 29, when the liquid inlet pipe 29 is communicated with the lower pipe 26 on the air pipe 24, the liquid in the air pipe 24 flows into the liquid inlet pipe 29.

[0039] The liquid outlet mechanism further comprises a liquid outlet gear 25 fixedly installed on the air pipe 24, which is used to drive the reversing gear 28 to rotate so as to connect the liquid inlet pipe 29 with the lower pipe 26.

[0040] The cooling mechanism comprises a cooling box 31 slidably installed on the vertical plate three 34, which is internally provided with a water pump connected with a cooling pipe 33 communicated with the cooling box 31, and the cooling box 31 is wound on the air pipe 24.

[0041] Specifically, the two ends of the cooling pipe 33 are communicated with the cooling box 31, and the middle part of the cooling pipe 33 is wound on the air pipe 24, so that the water in the cooling box 31 can be delivered into the cooling pipe 33 through the water pump to circulate back and forth, and the cooling box 31 is externally provided with a fan 32 connected with a motor.

[0042] The rotating mechanism comprises a rotating rod one 6 rotatably installed on the vertical plate one 4, and the two ends of the rotating rod one 6 are respectively slidably connected with the sliding block two 8 and the sliding block one 7, the sliding block one 7 is slidably installed on the vertical plate three 34, the sliding block two 8 is slidably installed on the vertical plate one 4, and the end of the sliding block two 8 away from the rotating rod one 6 is slidably connected with the meandering groove 10 on the rotating rod two 9, and the rotating rod one 6 is driven by a power source.

[0043] Specifically, the power source is a cylinder 5, the extending end of which is rotatably connected with the rotating rod one 6, and the cylinder 5 is hingedly connected with the mounting seat 3 fixedly installed on the vertical plate one 4.

[0044] Working principle: first, open the cover on the distillation barrel 2, then pour the liquid to be rectified into the distillation barrel 2 and close the cover.

[0045] Because the temperature regulating gears 16, 17, and 18 have different numbers of teeth, when the drive gear 14 passes through them, it can cause them to rotate at different angles. This allows the slide rod 19 to rotate at different angles, resulting in different resistance values ​​generated by the three sliding rheostats 21. Consequently, the heating plates 23 at different positions can generate different currents and power. It should be noted that, in the initial state, the resistance of the sliding rheostat 21 is fully connected to the circuit. By rotating the temperature-adjusting gears 16, 17, and 18, the resistance of the three sliding rheostats 21 connected to the circuit can be adjusted respectively. That is, since the number of teeth of the temperature-adjusting gear 16 is greater than the number of teeth of the drive gear 14, the angle at which the drive gear 14 drives the temperature-adjusting gear 16 to rotate is small. Therefore, the angle at which the temperature-adjusting gear 16 drives the slider 19 and the connector 20 through the shaft will also be small. As a result, the distance that the slider 19 moves through the connector 20 to move the slider in the sliding rheostat 21 will be less. In other words, when adjusting the resistance of the sliding rheostat 21 set at the temperature-adjusting gear 16, the resistance decreases very little. Since the number of teeth on the drive gear 14 is greater than that on the temperature-regulating gear 18, the temperature-regulating gear 18 will rotate a larger angle due to the drive gear 14. This causes the slide rod 19 and connector 20 at the temperature-regulating gear 18 to drive the slider of the sliding rheostat 21 at that location to slide a greater distance, thus reducing the resistance of the sliding rheostat 21 connected to the circuit. Whether the sliding of the slider in the sliding rheostat 21 decreases or increases the resistance depends on how the sliding rheostat 21 is wired, which is existing technology and can be implemented by those skilled in the art. In this embodiment, the smaller the movement distance of the slider in the sliding rheostat 21, the greater the resistance connected to the circuit.

[0046] When it is necessary to adjust the lowest distillation temperature so that the liquid with the lowest boiling point in the mixture is distilled out, cylinder 5 is activated, causing the extended end of cylinder 5 to extend. The extended end of cylinder 5 pushes the rotating rod 6 to rotate counterclockwise (to... Figure 3 (Based on the angle and direction), when the rotating rod 6 rotates, the left side of the rotating rod 6 and the slider 8 will lower, and the right side of the rotating rod 6 and the connection with the slider 7 will rise. The slider 7 serves to guide the rotating rod 6. Since the cylinder 5 and the mounting base 3 are hinged, the mounting base 3 will not restrict the rotation of the cylinder 5 and the rotating rod 6.

[0047] As the rotating rod 16 presses down on the slider 28 to make it slide down along the vertical plate 14, the slider 28 will slide along the loop 10 connected to the rotating rod 29, thereby causing the slider 28 to drive the rotating rod 29 to rotate clockwise (to... Figure 3 (Based on the angle and direction), the rotating rod 29 will rotate on the vertical plate 14. At this time, the end of the rotating rod 29 near the vertical plate 23 will rise. Then, the push rod 11 connected to the rotating rod 29 will drive the slider 32 to slide upward along the vertical plate 23. Since the push rod 11 and the slider 32 are rotatably connected, and the push rod 11 and the groove 10 are slidably engaged, the push rod 11 will not be stuck. During the upward sliding of the slider 32, the drive gear 14 fixedly connected to the slider 32 will move upward. In this way, the drive gear 14 will move from below the temperature regulating gear 16 towards the temperature regulating gear 16. When the drive gear 14 moves to contact the temperature regulating gear 16, the drive gear 14 meshes with the temperature regulating gear 16. In this way, the drive gear 14 fixedly installed on the slider 32 will drive the temperature regulating gear 16 to rotate. Of course, since the number of teeth on the temperature-adjusting gear 16 is greater than that on the driving gear 14, the temperature-adjusting gear 16 can only rotate a small angle. When the temperature-adjusting gear 16 rotates, the shaft fixedly connected to it will rotate on the vertical plate 13. This will cause the connector 20 at the other end of the shaft to rotate, which in turn will drive the slide rod 19 to rotate. The connector 20 at the other end of the slide rod 19 will then drive the sliding rheostat 21 to slide, thereby adjusting the resistance value of the sliding rheostat 21 connected to the circuit. That is, the circuit formed by the sliding rheostat 21, the heating plate 23, and the conductive post 22. Since the rotation angle of the temperature-adjusting gear 16 is very small, the rotation angle of the slide rod 19 will also be small. This will reduce the distance that the connector 20 moves the slider in the sliding rheostat 21, thus maximizing the resistance value of the circuit connected to the sliding rheostat 21. According to the formula:

[0048] U = IR 总

[0049] Where U represents voltage, I represents current, and R 总 This represents the total resistance of the sliding rheostat 21 and the heating plate 23.

[0050] It can be seen that when the resistance of the sliding rheostat 21 connected to the circuit is at its maximum, the total resistance in the circuit will increase (of course, this total resistance is relative to the resistance of the sliding rheostat 21 connected to the temperature regulating gear 3 18 and the slide bar 19). Therefore, when the overall voltage remains unchanged, the current is at its minimum.

[0051] Furthermore, in the process of moving upward with the driving gear 14 driven by the second rotating rod 9, the second rotating rod 9 will also drive the connecting column 15 through the meandering slot 10, so that the connecting column 15 fixedly installed on the distillation barrel 2 can drive the distillation barrel 2 to slide upward along the vertical plate 34, so that the distillation barrel 2 is moved to the height of the heating plate 23 communicating with the temperature adjusting gear 16, so that the heating plate 23 connected to the circuit can heat the distillation barrel 2.

[0052] Since the current in the circuit is increased, according to the formula:

[0053] Q = I 2 R 23

[0054] Where Q represents heat, I represents current, and R 23 represents the resistance of the heating plate 23.

[0055] It can be seen that since the current in the circuit is the smallest, the heat generated by the heating plate 23 is the smallest, so the temperature provided by the heating plate 23 to the distillation barrel 2 is the smallest, and at this time when the distillation barrel 2 is heated, the temperature of the liquid with the lowest boiling point is first reached, so that the liquid with the lowest boiling point is distilled.

[0056] In the process of moving before heating, the air pipe 24 connected to the distillation barrel 2 will also move with the distillation barrel 2, so that the cooling pipe 33 wound on the air pipe 24 will move with the cooling box 31, and the cooling box 31 will slide along the vertical plate 34. When the liquid outlet gear 25 moves to the meshing position with the lowermost reversing gear 28, the reversing gear 28 will be driven by the liquid outlet gear 25 to rotate on the vertical plate 34 through the center shaft, so that the collecting box 27 is rotated and the coil spring 30 is compressed. When the collecting box 27 rotates, the liquid inlet pipe 29 connected to the collecting box 27 will rotate, and the liquid inlet pipe 29 will gradually change from the vertical downward state to the horizontal position (as shown in Figure 8 , the two liquid inlet pipes 29 located above are downward, which is the initial state, as shown in Figure 9 , the liquid inlet pipe 29 in the horizontal state is a rotated state), the rotation of the liquid inlet pipe 29 is on one hand to avoid interference with the lifting of the air pipe 24, and on the other hand to make the liquid inlet pipe 29 rotate to communicate with the lower pipe 26.

[0057] After the distillation barrel 2 is heated, the liquid in the distillation barrel 2 reaches the boiling point and is evaporated into the air pipe 24, at the same time, the water pump in the cooling box 31 is started, and the water pump continuously sends water into the cooling pipe 33, so that the cold water in the cooling pipe 33 cools the gas in the air pipe 24, thereby liquefying the gas, and the liquefied liquid flows into the liquid inlet pipe 29 through the lower pipe 26, and then enters the collection box 27 to complete the collection. The motor provided on the cooling box 31 also drives the fan 32 to rotate, and the fan 32 also assists in cooling.

[0058] When the temperature needs to be increased, and the liquid with a higher boiling point is distilled, the air cylinder 5 is started again, so that the extended end of the air cylinder 5 drives the rotating rod 6 to rotate, and through the transmission of the rotating rod 6 and the rotating rod 9, the drive gear 14 on the rotating rod 9 moves to the position meshing with the temperature adjusting gear two 17 through the temperature adjusting gear one 16. At this time, the drive gear 14 meshes with the temperature adjusting gear two 17, and since the number of teeth of the temperature adjusting gear two 17 is less than that of the temperature adjusting gear one 16, the angle of rotation of the temperature adjusting gear two 17 driven by the drive gear 14 is greater than that of the temperature adjusting gear one 16. Therefore, since the angle of rotation of the temperature adjusting gear two 17 is greater than that of the temperature adjusting gear one 16, the rotating shaft and the slide rod 19 connected to the temperature adjusting gear two 17 will rotate at a larger angle, that is, the sliding rheostat 21 provided at the temperature adjusting gear two 17 will move a larger distance under the push of the connecting head 20. Therefore, the resistance value of the sliding rheostat 21 connected to the circuit will decrease (compared to the resistance value of the sliding rheostat 21 provided at the temperature adjusting gear one 16), so that the current in the circuit will increase, and the heat generated will also increase, thereby achieving a higher boiling point temperature, and distilling the liquid with a high boiling point temperature. Of course, during the adjustment process, the distillation barrel 2 will also move upward to the position of the heating plate 23 corresponding to the temperature adjusting gear two 17.

[0059] Since the number of teeth of the temperature adjusting gear three 18 is the smallest, if the drive gear 14 drives the temperature adjusting gear three 18 to rotate, the angle of rotation of the temperature adjusting gear three 18 is the largest, that is, the angle of rotation of the rotating shaft and the slide rod 19 connected to the temperature adjusting gear three 18 is the largest. Therefore, the sliding piece in the sliding rheostat 21 provided at the position of the temperature adjusting gear three 18 moves the largest distance, that is, the resistance value of the circuit at this time is the smallest, and the heat generated is the largest, so that the liquid with the highest boiling point can be distilled.

In addition, modifications can be made to the features and embodiments described to accommodate specific situations and materials without departing from the spirit and scope of the application.
