A driving rod 12 passes through and is threadedly connected to the driving seat 20;

[0041] In addition, the synchronous movement of the driving seat 20 and the lifting seat 13 can be achieved in another way. The driving seat 20 and the lifting seat 13 are connected by a U-shaped connecting rod to achieve synchronous movement of the driving seat 20 and the lifting seat 13, and openings are set on the partition 7 and the concentration outer cover 2 to allow the connecting rod to pass through.

[0042] The driving rod 12 and the rotating rod 9 both extend to above the partition 7;

[0043] A sealing structure is provided at the connection between the partition 7 and the driving rod 12 and the rotating rod 9 to ensure that steam does not enter above the partition 7 during the rotation of the driving rod 12 and the rotating rod 9, thereby preventing the integrated driving assembly 8 from being damaged by steam.

[0044] The integrated drive assembly 8 includes an inner ring seat 24 rotatably connected to the top of the partition 7, an outer ring seat 25 is provided on the outer side of the inner ring seat 24, a fixing rod 26 is fixedly connected between the top of the inner ring seat 24 and the outer ring seat 25, the top of the rotating rod 9 is coaxially fixedly connected to the first passive gear 28, the top of the driving rod 12 is coaxially fixedly connected to the second passive gear 29, an annular gear ring 30 meshing with the first passive gear 28 is fixedly provided on the outer side of the inner ring seat 24, a forward driving tooth segment 31 meshing with the second passive gear 29 is provided on the outer side of the inner ring seat 24, and a reverse driving tooth segment 32 meshing with the second passive gear 29 is provided on the inner side of the outer ring seat 25.

[0045] A driving blank section is provided between the forward driving tooth section 31 and the reverse driving tooth section 32 , and neither the inner ring seat 24 nor the outer ring seat 25 on the driving blank section has a tooth structure for driving the second passive gear 29 .

[0046] The multiple groups of stirring components 5 and the multiple groups of lifting and evaporating components 6 are distributed at intervals, and the multiple groups of stirring components 5 and the multiple groups of lifting and evaporating components 6 are arranged at equal distances around the circumference.

[0047] A lifting slot 19 is provided between the lifting cover 14 and the vertical carrier plate 11 .

[0048] A driving motor 22 is fixedly connected to the top of the concentrating outer cover 2 , and the output shaft of the driving motor 22 is coaxially fixedly connected to a driving gear 23 . An inner gear ring 27 is provided on the inner side of the inner ring seat 24 , and the driving gear 23 is meshedly connected to the inner gear ring 27 .

[0049] The forward driving tooth segment 31 and the reverse driving tooth segment 32 do not intersect each other on the circumferential trajectory.

[0050] An electric heating component is arranged in the base 1. The electric heating component is used to heat the dimer acid solution, and the electric heating component adopts a heating device in the prior art.

[0051] The top of the concentrating outer cover 2 is fixedly connected with a feed pipe 4 and an exhaust pipe 3 , both of which extend to below the partition 7 , and a discharge port is provided at one side of the bottom of the concentrating outer cover 2 .

[0052] The exhaust pipe 3 is connected to an external negative pressure source, and the evaporation efficiency of the dimer acid solution can be further improved by reducing the air pressure in the concentrating outer cover 2 .

[0053] The inner side of the lifting seat 13 is provided with a scraping protrusion 21 corresponding to the straight groove 15 .

[0054] When the second passive gear 29 moves to the blank section, the second passive gear 29 does not rotate. At this time, the lifting seat 13 is located outside the inclined slot 16 , and the dimer acid solution is in a state of continuous release from the inclined slot 16 .

[0055] The details are as follows: during the upward movement of the lifting seat 13, the scraping protrusion 21 closes the straight groove 15, so that the dimer acid solution cannot flow downward along the straight groove 15; when the scraping protrusion 21 moves into the inclined groove 16, a gap is formed between the scraping protrusion 21 and the vertical carrier 11, and the dimer acid solution flows out of the gap and flows downward along the straight groove 15; when the lifting seat 13 drives the scraping protrusion 21 to move downward, the scraping protrusion 21 moves downward along the straight groove 15, scraping the evaporated dimer acid solution downward to prevent the dimer acid solution from adhering to the vertical carrier 11 for a long time and causing adhesion.

[0056] A liquid inlet valve is arranged in the feed pipe 4, and a liquid outlet valve is arranged on the discharge port. Both the liquid inlet valve and the liquid outlet valve are electric valves, which are convenient for information control.

[0057] During the implementation of the present invention, the dimer acid solution is first released from the feed pipe 4 into the concentration outer cover 2, and then the liquid inlet valve is closed, and then the electric heating component in the control base 1 is started to heat the dimer acid solution to a set temperature, so that the dimer acid solution is evaporated and concentrated;

[0058] In order to achieve a uniform temperature of the dimer acid solution, the driving motor 22 is controlled to start, the driving motor 22 drives the driving gear 23 to rotate, and the driving gear 23 drives the inner ring seat 24 to rotate when meshing with the inner gear ring 27, thereby driving the first passive gear 28 to rotate through the annular gear ring 30, so that the rotating rod 9 drives the stirring paddle 10 to rotate, and the stirring paddle 10 drives the dimer acid solution in the concentrating outer cover 2 to flow when rotating, thereby achieving a uniform temperature of the dimer acid solution;

[0059] In order to improve the evaporation efficiency of the dimer acid solution, the inner ring seat 24 drives the outer ring seat 25 to rotate synchronously when rotating, and the positive driving tooth segment 31 first meshes with the second passive gear 29, driving the second passive gear 29 to rotate positively, and the second passive gear 29 drives the driving rod 12 to rotate positively, so that the driving seat 20 moves upward, and under the attraction of the inner magnet 17 and the outer magnet 18, the lifting seat 13 is driven to move upward, and at this time, the lifting groove 19 is filled with dimer acid solution;

[0060] When the forward driving tooth segment 31 is out of contact with the second passive gear 29, the scraping protrusion 21 on the inner side of the lifting seat 13 moves into the inclined groove 16, and the dimer acid solution flows into the inclined groove 16 and flows downward along the inner wall of the straight groove 15. The evaporation area can be increased during the downward flow of the dimer acid solution.

[0061] As the inner ring seat 24 and the outer ring seat 25 continue to rotate, the reverse drive ring gear contacts and meshes with the second passive gear 29, driving the second passive gear 29 to rotate in the reverse direction, thereby causing the drive rod 12 to rotate in the reverse direction, and finally causing the lifting seat 13 to move downward, allowing the lifting seat 13 and the lifting cover 14 to re-enter the dimer acid solution at the bottom of the concentrated outer cover 2.

[0062] Since there is a driving blank section between the forward driving tooth segment 31 and the reverse driving tooth segment 32, when the second passive gear 29 is located at the driving blank section, the dimer acid solution in the lifting tank 19 is gradually released until the dimer acid solution is completely released.

[0063] After the dimer acid solution is concentrated, the liquid outlet valve is controlled to open to release the concentrated dimer acid solution.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
