[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-2 The utility model provides an embodiment: a distillation device for processing triethylamine, a chemical raw material, comprises a reactor 1, characterized in that: a valve 2 is fixedly connected to the side wall of the reactor 1, a bolt 3 is threadedly connected to the inside of the valve 2, a support platform 4 is fixedly connected to the side wall of the reactor 1, a cylinder 5 is fixedly connected to the side wall of the support platform 4, a push rod 6 is fixedly connected to the output end of the cylinder 5, one end of the push rod 6 is fixedly connected to a connecting rod 1 7, a connecting rod 2 8 is rotatably connected to the side wall of the connecting rod 1 7, a connecting shaft 9 is rotatably connected to the inside of the connecting rod 2 8, an outer wall of the connecting shaft 9 is rotatably connected to the inside of the valve 2, a valve cover 10 is rotatably connected to one end of the connecting shaft 9, the valve cover 10 is slidably connected to the inside of the valve 2, a drain port 11 is provided inside the valve 2, and a maintenance component is arranged on the top of the reactor 1.

[0023] Specifically, when the cylinder 5 is started, it will apply a push-pull force to the push rod 6. After the push rod 6 receives this force, it will be displaced. The movement of the connecting rod 1 7 not only promotes the rotation of the connecting rod 2 8, but also changes the inclination angle of the connecting rod 2 8. This combination of rotation and inclination causes the connecting shaft 9 to rotate inside the valve 2. The rotation of the connecting shaft 9 drives the movement of the valve cover 10, causing it to slide inside the valve 2, thereby controlling the opening and closing state of the drain port 11. Through this structure, the operator can freely control the opening and closing of the drain port 11 as needed, thereby achieving effective discharge of waste liquid inside the distillation device. This not only reduces the risk of waste liquid leakage, but also effectively avoids secondary pollution caused by chemical waste to the environment or human body, not only improves the operating efficiency of the distillation device, but also greatly improves its environmental performance.

[0024] Reference Figure 3 The maintenance component includes a tower body 12, the bottom of the tower body 12 is fixedly connected to the upper surface of the reactor 1, the upper surface of the tower body 12 is slidably connected to a tower 13, the inner thread of the tower 13 is connected to a connecting plate 14, the side wall of the connecting plate 14 is fixedly connected to a handle 15, the side wall of the tower 13 is fixedly connected to a connecting column 16, the outer wall of the connecting column 16 is rotatably connected to a sleeve column 17, the side wall of the sleeve column 17 is fixedly connected to a clamping plate 18, the side wall of the sleeve column 17 is fixedly connected to a connecting plate 19, the side wall of the connecting plate 19 is fixedly connected to a pressure plate 20, and the surface of the pressure plate 20 is fixedly connected to a spring 21.

[0025] Specifically, pressing the pressure plate 20 causes the connecting plate 19 to start moving. The movement of the connecting plate 19 is synchronized with the movement of the side wall of the connecting column 16, and at the same time, the connecting column 16 starts to rotate on the outer wall of the handle 15. This coordinated action allows the card plate 18 on the side wall of the connecting column 16 to unlock the connecting disk 14, allowing the handle 15 to rotate. Rotating the handle 15 drives the connecting disk 14 to rotate together and detach from the tower 13. Once the connecting disk 14 is removed, the tower 13 can slide out from the inside of the tower body 12, providing maintenance personnel with a passage to enter the tower body 12 and the reactor 1 for necessary maintenance. At the same time, the reset function of the spring 21 plays an important role. It ensures that the handle 15 will not be easily rotated, thereby preventing the device from being accidentally opened. This design not only improves the safety of the device, but also reduces the difficulty of maintenance, providing a strong guarantee for the normal operation of the distillation device. Therefore, this design not only improves the convenience of operation, but also improves the overall efficiency and reliability of the device.

[0026] Working principle: when it is necessary to discharge the waste liquid inside the distillation device, first start the cylinder 5, and the cylinder 5 outputs a push-pull force to the push rod 6. After the push rod 6 is subjected to the force, it drives the connecting rod 1 7 at one end thereof to move synchronously. While the connecting rod 1 7 moves, it pushes the connecting rod 2 8 to rotate and change its own inclination angle. The rotation of the connecting rod 2 8 drives the connecting shaft 9 to rotate inside the valve 2. While the connecting shaft 9 rotates, it drives the valve cover 10 at one end thereof to rotate along. While the valve cover 10 slides inside the valve 2, it can open and close the discharge port 11 inside the valve 2. With this structure, the waste liquid inside the reactor 1 can be freely discharged or blocked, which reduces the possibility of waste liquid leakage, avoids secondary pollution to the environment or human body caused by chemical fertilizers, and improves the environmental protection performance of this device. When opening the tower 13 to perform maintenance and cleaning on the tower body 12 and the interior of the reactor 1, first press the pressure plate 20, which compresses the spring 21 and drives the connecting plate 19 to move. While the connecting plate 19 moves on the side wall of the connecting column 16, the connecting column 16 rotates on the outer wall of the handle 15. The rotation of the connecting column 16 drives the clamping plate 18 on its side wall to unlock the connecting disk 14, and then the handle 15 can be rotated to drive the connecting disk 14 to follow the rotation and detach from the tower 13. After the connecting disk 14 is removed, the tower 13 can slide out from the inside of the tower body 12, and then the necessary maintenance can be performed on the tower body 12 and the inside of the reactor 1. At the same time, the resetting of the spring 21 can prevent the handle 15 from being easily rotated, which greatly reduces the maintenance difficulty of the distillation device and provides a strong guarantee for the normal operation of the distillation device.

[0027] Finally, it should be noted that the above 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 make equivalent substitutions for some of the technical features therein.
