DETAILED DESCRIPTION

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Example 1: refer to Figure 1 and Figure 2, a high-efficiency evaporation reactor, including an evaporation box 1, the interior of the evaporation box 1 is heated by an external heating device, and also includes a centrifugal sprinkling evaporation mechanism, including a plurality of evaporation plates 4 installed in the evaporation box 1, a plurality of delay plates are provided on the top wall of the evaporation plate 4, and the delay plates are staggered on the top wall of the evaporation plate 4, and the plurality of evaporation plates 4 are arranged from top to bottom, and the evaporation plate is in an inverted funnel shape, a collecting trough 2 is provided on the bottom wall of the evaporation box 1, a plurality of guide rods 3 are fixedly installed in the collecting trough 2, the evaporation plate 4 is fixedly installed on the guide rod 3, a recovery groove is provided at the edge of the evaporation plate 4, and a reflux groove is opened on the guide rod 3, and the recovery groove and the reflux groove are connected, a rotating tube 5 is rotatably installed at the center of the evaporation plate 4, and a dispersion plate 6 is connected to the outside of the rotating tube 5, and the dispersion plate 6 is provided with a plurality of dispersion holes , an insulation cover 17 is provided on the top of the evaporation box 1. When the rotating tube 5 rotates, the liquid is sprinkled on the evaporation plate 4 through the dispersion plate 6. A driving member for driving the rotating tube 5 to rotate is provided on the top wall of the evaporation box 1 (the driving member can be a motor, and the specific transmission method can be adjusted and selected according to actual needs). A return pipe 7 is movably inserted in the rotating tube 5. The bottom end of the return pipe 7 extends into the collecting tank 2, and the top of the return pipe 7 movably passes through the top of the rotating tube 5. A first piston rod 8 is movably inserted at the top of the return pipe 7. A transmission frame 9 is provided on the top wall of the evaporation box 1, and a transmission groove is opened on the bottom wall of the transmission frame 9. A transmission rod is fixedly installed on the top of the first piston rod 8, and the transmission rod is slidably connected to the transmission groove. A reflux hole is opened on the side wall of the return pipe 7, and the reflux hole is communicated with the inner cavity of the rotating tube 5.

[0021] like Figure 3 As shown, the solution is placed in the collection tank 2, and then extracted into the rotating tube 5 by the reflux pipe 7. The driving member drives the rotating tube 5 to rotate, and the solution in the rotating tube 5 is thrown out by the centrifugal force, and sprinkled out from the dispersion holes on the dispersion plate 6 and sprinkled on the upper surface of the evaporation plate 4. The solution in the form of water droplets is more easily evaporated. The dispersion plate 6 is in the shape of an inverted funnel. Under the action of gravity, the solution that has not been evaporated flows into the recovery tank, and then flows back to the collection tank 2 along the guide rod 3. It will also be evaporated during the flow process.

[0022] At the same time, when the rotating tube 5 drives the dispersion plate 6 to rotate and sprinkle water, an airflow is also generated. The direction of the airflow is from the dispersion plate 6 toward the reaction tube 20, blowing steam toward the reaction tube 20 to facilitate its extraction, thereby improving the subsequent reaction quality and reaction efficiency.

[0023] Specifically, when the driving member drives the rotating tube 5 to rotate, it will drive the reflux tube 7 to rotate together, and the reflux tube 7 drives the first piston rod 8 to rotate together. The angle between the transmission rod at the top of the first piston rod 8 and the first piston rod 8 is a right angle. When the transmission rod rotates with the first piston rod 8, it will slide along the transmission groove. The first piston rod 8 is guided by the transmission groove to move back and forth, thereby changing the air pressure in the reflux tube 7. When the first piston rod 8 moves into the reflux tube 7, the solution in the reflux tube 7 enters the rotating tube 5 through the reflux hole, and when the first piston rod 8 moves to the outside of the reflux tube 7, the solution in the collecting tank 2 is extracted through its bottom end. A one-way valve is provided at the reflux hole and the bottom end of the reflux tube 7.

[0024] It is worth noting that a delay plate is provided on the dispersion plate 6, which is not shown in the figure and is in the shape of a convex block. Its main purpose is to block the solution when it flows on the dispersion plate 6, thereby increasing the flow (residence) time of the solution on the dispersion plate 6 and improving the efficiency and quality of evaporation.

[0025] refer to Figure 2 A guide frame 10 is fixedly installed in the evaporation box 1, and a plurality of diversion holes are provided on the guide frame 10. A diversion frame 11 is provided on the top wall of the guide frame 10, and a plurality of liquid outlet holes are opened on the diversion frame 11. A conveying member is fixedly installed on the top wall of the evaporation box 1, and the conveying member is used to extract the liquid at the bottom of the evaporation box 1 and transport it to the diversion frame 11. A piston tube 12 is provided on the top of the evaporation box 1, and a second piston rod 13 is movably inserted on the top wall of the piston tube 12. A transmission plate 14 is fixedly installed on the top of the second piston rod 13, and a fixed rod 15 is fixedly installed on the transmission plate 14. The fixed rod 15 and the first piston rod 8 are rotatably connected, and the first piston rod 8 and the fixed rod 15 are lifted and lowered synchronously. A liquid outlet pipe is connected between the piston tube 12 and the diversion frame 11, and a liquid inlet pipe 16 is provided on the bottom wall of the piston tube 12.

[0026] like Figure 3 As shown, as the first piston rod 8 reciprocates up and down, it drives the transmission plate 14 to slide up and down via the fixed rod 15, thereby driving the second piston rod 13 to slide up and down in the piston tube 12. As the second piston rod 13 moves downward into the piston tube 12, the solution in the piston tube 12 enters the diverter frame 11 and flows down along the guide frame 10. The guide frame 10 is provided with multiple diverter holes. This not only prolongs the solution's retention time and improves evaporation efficiency, but also increases the heating area, also improving evaporation efficiency. As the second piston rod 13 moves upward, the solution at the bottom of the evaporation tank 1 is extracted through the liquid inlet pipe 16. The interior and exterior of the collection tank 2 contain two different solutions. The two vapors evaporate from the dispersion plate 6 and the guide frame 10, respectively. A mixing reaction occurs through these two vapors.

[0027] Example 2: The intermittent exhaust reaction mechanism includes a plurality of collecting tubes 19 rotatably mounted in the evaporation box 1, and a plurality of reaction tubes 20 are fixedly sleeved on the collecting tubes 19, and an air inlet pipe 21 is provided on the reaction tube 20. The reaction tube 20 is used to extract the steam in the evaporation box 1. The intermittent exhaust reaction mechanism also includes a liquid outlet rack 18 fixedly mounted in the evaporation box 1, the collecting tube 19 is rotatably connected to the liquid outlet rack 18, a plurality of liquid outlet holes are opened on the side wall of the collecting tube 19, and a one-way valve is respectively provided on the liquid outlet hole and the air inlet pipe 21. The liquid outlet rack 18 is externally connected to a condenser. A third piston rod 22 is slidably provided in the rotating reaction tube 20, and the top end of the third piston rod 22 movably penetrates the top wall of the reaction tube 20. The top end of the third piston rod 22 is fixedly mounted with a transmission ring 2 9. Multiple transmission rings 29 are connected to a vertical rod together. A threaded rod 26 is fixedly installed on the top of the collecting tube 19. The top of the threaded rod 26 rotates and penetrates the top wall of the evaporator box 1. An annular frame 28 is fixedly installed on the bottom wall of the fixed rod 15. A threaded tube 27 is fixedly installed on the bottom wall of the annular frame 28. The threaded tube 27 and the threaded rod 26 are threadedly connected, and the vertical rod movably penetrates the top wall of the evaporator box 1 and is fixedly connected to the threaded tube 27. When the fixed rod 15 is raised or lowered, the threaded rod 26 and the collecting tube 19 rotate back and forth. A first stirring plate 23 is fixedly installed on the bottom wall of the third piston rod 22, and a second stirring plate 24 is movably inserted on the bottom wall of the first stirring plate 23. A sliding tube 25 is slidably installed at the liquid outlet, and a return spring is provided at the sliding connection.

[0028] In order to further improve the efficiency of the reaction, Figure 5 As shown, a reaction tube 20 is positioned between the flow guide frame 10 and the dispersion plate 6. As the fixed rod 15 reciprocates up and down, it simultaneously drives multiple threaded tubes 27 to reciprocate up and down via the annular frame 28. On the one hand, as the threaded tubes 27 reciprocate up and down, the threaded drive drives the threaded rod 26 to rotate back and forth, thereby driving the reaction tube 20 to reciprocate, thereby changing the position of steam extraction and improving extraction efficiency and quality. On the other hand, as the threaded tubes 27 move up and down, they drive multiple transmission rings 29 to slide up and down via the vertical rods. These transmission rings drive the third piston rod 22 to slide within the reaction tube 20. As the third piston rod 22 moves upward, it extracts external steam through the intake pipe 21. As the third piston rod 22 moves downward, it pressurizes the extracted steam, improving the efficiency and quality of both reactions. Subsequently, the sliding tube 25 is pressed downward, opening the liquid outlet. The reacted mixed steam (or mixed liquid) enters the liquid outlet frame 18 through the liquid outlet and exits the evaporator 1, where it is liquefied through condensation or other means.
