Description

Technical Field

[0001] The utility model relates to the technical field of double-tower distillation, in particular to a double-tower high-efficiency distillation device. Background Art

[0002] The working principle of the double-tower distillation tower is mainly based on the fractionation process of different component vapors in the tower. After the mixture is heated in the tower, the volatile components are first converted into vapor and rise to the top of the tower. As the vapor rises and gradually cools, the components are fractionated. The volatile components are condensed at the top of the tower and then flow back into the tower, where they are heated and evaporated again, thereby obtaining a purer component.

[0003] When the existing double-tower distillation tower distills different liquids, since the boiling points, i.e., evaporation points, of different liquids are inconsistent, it is necessary to adjust the internal pressure according to the different liquids to ensure the consistency of the boiling points, so as to achieve the most efficient evaporation method. However, the existing methods of adjusting the pressure are generally more complicated, or require manual adjustment, which is more troublesome.

[0004] To this end, those skilled in the art have proposed a double-tower high-efficiency distillation device to solve the problems raised by the background technology. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] As attached Figure 1 To Attachment Figure 4 As shown:

[0022] Embodiment 1: The utility model provides a double-tower high-efficiency distillation device, comprising a first distillation tower 1, a control panel 11 is installed on the outer side wall of the first distillation tower 1, a second distillation tower 12 is installed on the outer side wall of the control panel 11, a transmission pipe 13 is installed at the output end of the first distillation tower 1, the other end of the transmission pipe 13 is installed at the input end of the second distillation tower 12, and a dewatering pipe 14 is installed at the top of the second distillation tower 12;

[0023] A pressure measuring mechanism, which is arranged on the outer side walls of the first distillation tower 1 and the second distillation tower 12;

[0024] An evaporation mechanism is arranged on the inner side walls of the first distillation tower 1 and the second distillation tower 12, and the pressure measuring mechanism includes a pressure gauge 2, which is installed on the outer side wall of the second distillation tower 12, and a pointer 21 is installed on the inner side wall of the pressure gauge 2. A connecting groove 22 is opened on the outer side wall of the pressure gauge 2, and a sliding magnet 23 is slidably connected to the outer side wall of the connecting groove 22. A connecting collar 24 is installed on the outer side wall of the pressure gauge 2, and a connecting screw 25 is slidably connected to the inner side of the connecting collar 24. One end of the connecting screw 25 is threadedly connected to a sliding block 26, and the other end of the connecting screw 25 is fixedly connected to a connecting handle 27, and an induction trigger 28 is installed on the outer side wall of the sliding block 26.

[0025] Specifically, through the connection between the connecting groove 22 and the sliding magnet 23, the connecting groove 22 can limit the sliding magnet 23 and facilitate the sliding magnet 23 to slide in the connecting groove 22. The sliding magnet 23 and the pointer 21 are both magnets, and can attract each other so that the pointer 21 drives the sliding magnet 23 to slide.

[0026] The evaporation mechanism includes a closed baffle 3, which is arranged on the inner wall of the second distillation tower 12. The top of the closed baffle 3 is fixedly connected to a conical drainage tube 31, and the top of the conical drainage tube 31 is provided with a diverging pipe 32. The connecting screw 25 can be extended or shortened by adjusting the position of the connecting screw 25 in the sliding block 26, so that the connecting screw 25 can drive the connecting handles 27 on both sides to be tightly fixed to the sliding block 26 and the connecting collar 24.

[0027] Specifically, by disposing the conical drainage tube 31 , it is convenient to gather the water vapor and transmit it to the diffusion pipe 32 .

[0028] As can be seen from the above, when the device is needed, the position of the sliding block 26 is first adjusted according to the type of distilled liquid, and the connecting handle 27 is rotated to allow the connecting handle 27 to slightly disengage the connecting screw 25 from the sliding block 26 so that the sliding block 26 can slide. The interval of the two sliding blocks 26 is adjusted by the scale on the outside of the pressure gauge 2, wherein the sliding magnet 23 is always between the two sliding blocks 26. After the adjustment is completed, the pointer 21 starts to increase the pressure. If there is no pressure inside, the sliding magnet 23 will always stay at the position of one of the induction triggers 28, and the inside will always be pressurized. When the pointer 21 rotates to the interval, the internal pressure interval can be controlled by controlling the contact between the sliding magnet 23 and the two induction triggers 28, so as to facilitate better pressurization. When heating is performed inside the first distillation tower 1, the water at the bottom of the closed baffle 3 is first heated. The water at the bottom of the closed baffle 3 is heated to the boiling point and enters the diverging pipe 32 through the conical drainage tube 31. The liquid inside the first distillation tower 1 and the second distillation tower 12 is heated and distilled through the diverging pipe 32.

[0029] System Components:

[0030] Sliding magnet 23: can move on the connecting groove 22 and is controlled by external pressure.

[0031] Connecting groove 22: track for the sliding magnet 23 to move.

[0032] Inductive triggers 28: two, respectively installed at two specific positions of the slideway, for detecting the position of the slider.

[0033] Pressure control unit: Increases or decreases pressure according to the signal from the trigger sensor.

[0035] Workflow:

[0036] Initialization: The system starts, the sliding magnet 23 is in the initial position, and the pressure control unit is set to the basic pressure.

[0037] Movement of the sliding magnet 23: External pressure pushes the sliding magnet 23 to move on the connecting groove 22.

[0038] Position detection: When the sliding magnet 23 moves to a position of a certain sensor trigger 28, the sensor will send a signal to the control system.

[0039] Signal processing: After receiving the signal from the induction trigger 28, the control system determines the current position of the sliding magnet 23.

[0040] Pressure adjustment:

[0041] If the slider triggers the boost sensor, the control system will instruct the pressure control unit to increase the pressure.

[0042] If the slider triggers the pressure reducing sensor, the control system will instruct the pressure control unit to reduce the pressure.
