[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please refer to the accompanying diagrams for all instruction manuals:

[0024] A high-efficiency connection device for a distillation kettle and a distillation column includes a base 1, a distillation kettle 2 and a distillation column 3. The distillation kettle 2 is located on the base 1. A support plate 4 is fixedly installed on the base 1. An adjustable and controllable connection mechanism is provided between the support plate 4 and the distillation kettle 3. A quick docking mechanism is provided between the distillation kettle 2 and the distillation column 3.

[0025] The adjustable controllable connection mechanism includes a protrusion 5 on the support plate 4, a groove 6 inside the protrusion 5, a screw 7 rotatably connected inside the groove 6, a moving block 8 threadedly connected to the screw 7, a U-shaped rod 9 inserted into the moving block 8, a motor 10 fixedly installed on the support plate 4, the output end of the motor 10 fixedly connected to the screw 7, a connecting block 11 fixedly installed on the distillation column 3, the connecting block 11 inserted into the U-shaped rod 9, and the connecting block 11 and the moving block 8 fitting together.

[0026] As can be seen from the above description, the connecting block 11 of the distillation column 3 is placed in the groove 6 and positioned by the U-shaped rod 9. Then, the motor 10 drives the distillation column 3 to descend and dock with the distillation kettle 2 below.

[0027] As a technical optimization of this utility model, the quick docking mechanism includes a pipe 12 located on the distillation kettle 2 and a pipe 13 located on the distillation column 3. A spring 14 is fixedly installed inside the pipe 12, and a conical piston 15 is fixedly installed on the spring 14. The inner wall of the pipe 12 and the conical piston 15 fit together. A top block 16 is fixedly installed on the conical piston 15. A limit ring 17 is fixedly installed outside the pipe 12, and a limit ring 17 is fixedly installed on the limit ring 17. There is a second spring 18, and a closed tube 19 is fixedly installed on the second spring 18. A number of balls 20 are evenly arranged on the first pipe 12 corresponding to the closed tube 19. A third spring 21 is fixedly installed on the second pipe 13, and a conical piston 22 is fixedly installed on the third spring 21. A top block 23 is fixedly installed on the conical piston 22. The conical piston 22 fits into the inner wall of the second pipe 13. The outer wall of the second pipe 13 is provided with an arc-shaped groove 24. The second pipe 13 fits into the first pipe 12.

[0028] As described above, when pipe 12 and pipe 23 are connected, the outer closed tube 19 is first pulled downwards, compressing spring 28. Then, pipe 23 is inserted into the opening of pipe 12. During insertion, the ball bearing 20, no longer restricted by the closed tube 19, can move on pipe 12. Pipe 23 can evenly push the ball bearing 20 open. Simultaneously, top block 16 and top block 23 first contact internally, causing the conical piston 15 inside pipe 12 to compress spring 14, and the conical piston 22 inside pipe 23 to compress spring 31. Since spring 14 and spring 321 are of the same type and model, and their deformation distances are the same, the conical piston 15 and conical piston 22 no longer fit with pipe 12 and pipe 23, creating a gap in the middle. This allows the two ends of pipe 12 and pipe 23 to be connected, achieving a passage. Once pipe 23 reaches the innermost side of pipe 12 and can no longer advance, the closed tube 19 is released directly. Through the elastic force of spring 28, the closed tube 19 is reset, allowing the ball 20 to be stably locked in the arc-shaped groove 24, thus effectively connecting pipe 12 and pipe 23.

[0029] As a technical optimization of this utility model, pipe 12 is provided with sealing ring 25 and sealing ring 26 corresponding to pipe 23;

[0030] As can be seen from the above description, sealing ring 25 and sealing ring 26 can effectively seal the leak-prone areas in pipe 12 and pipe 23, thereby improving the sealing performance.

[0031] As a technical optimization of this utility model, top block 16 and top block 23 are located on the same axis;

[0032] As can be seen from the above description, when connecting pipe 12 and pipe 23, the precise connection between top block 16 and top block 23 enables pipe 12 and pipe 23 to be quickly connected.

[0033] As a technical optimization of this utility model, the movable block 8 is slidably connected to the groove 6;

[0034] As can be seen from the above description, the connection method of the movable connection enables the movable block 8 to move more stably within the groove 6.

[0035] As a technical optimization of this utility model, reinforcing ribs 27 are symmetrically fixedly installed on the movable block 8, and a collar 28 is fixedly connected to the reinforcing ribs 27. The collar 28 is in contact with the distillation column 3.

[0036] As can be seen from the above description, the reinforcing rib 27 can increase the firmness of the connection between the moving block 8 and the distillation column 3, and together with the collar 28, it can better hold the distillation column 3.

[0037] The working process of this utility model is as follows:

[0038] Place the distillation column 3 on the collar 28 and make the connecting block 11 snap into the groove 6, then position it by the U-shaped rod 9; then control the motor 10 to work, drive the screw 7 to rotate, so that the distillation column 3 descends, so that the first pipe 12 and the second pipe 13 are connected. During the connection process, pull down the closing tube 19 so that the second pipe 13 can smoothly enter the first pipe 12. After it is fully entered, open the closing tube 19 to complete the fixation.

[0039] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
