[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a rotary evaporation concentration device, including a concentration tank 1. A second stirring mechanism is installed inside the concentration tank 1 via a dual-shaft motor 8. The dual-shaft motor 8 is fixedly mounted on the top of the concentration tank 1. A preheating tank 2 is fixedly mounted on the top of the dual-shaft motor 8 via an exhaust mechanism. The exhaust mechanism includes an exhaust pipe 4, which is S-shaped and fixedly mounted inside the preheating tank 2. The bottom end of the exhaust pipe 4 is fixedly mounted inside the top end of the concentration tank 1, and the top end of the exhaust pipe 4 is mounted on the top of the preheating tank 2. A connecting pipe 6 is fixedly installed between the bottom end of the preheating tank 2 and the top end of the concentration tank 1. A regulating valve is fixedly installed on the connecting pipe 6. Water vapor generated inside the concentration tank 1 is introduced into the preheating tank 2 through the exhaust pipe 4, facilitating the absorption of heat from the water vapor by the liquid fertilizer in the preheating tank 2, avoiding direct discharge and energy waste. Simultaneously, it preheats the liquid fertilizer in the preheating tank 2, facilitating subsequent concentration of the liquid fertilizer.

[0021] In this embodiment, the second stirring mechanism includes a second stirring paddle 10, which is rotatably installed at the center of the inside of the concentration tank 1. The top of the second stirring paddle 10 is fixedly connected to the bottom output shaft of the dual-axis motor 8. A straight resistance wire is fixedly installed inside the second stirring paddle 10, and an electric brush is installed at the top of the second stirring paddle 10 corresponding to the inside of the concentration tank 1. The straight resistance wire and the electric brush are electrically connected. An inner cavity 11 is opened inside the inner wall of the concentration tank 1, and a spiral resistance wire 12 is fixedly installed inside the inner cavity 11. The second stirring paddle 10 rotates under the drive of the dual-axis motor 8, which will not cause harm to the staff. The second stirring paddle 10 and the straight resistance wire can heat the liquid fertilizer inside the concentration tank 1. The cooperation of the straight resistance wire and the spiral resistance wire 12 facilitates simultaneous heating of the liquid fertilizer from the inside and outside, which can improve the heating and concentration efficiency of the liquid fertilizer.

[0022] In this embodiment, the preheating box 2 is equipped with a first stirring mechanism, which includes a first stirring paddle 9. The first stirring paddle 9 is rotatably installed inside the preheating box 2. The bottom end of the first stirring paddle 9 is fixedly connected to the top output shaft of the dual-shaft motor 8. The bottom end of the exhaust pipe 4 is located on both sides of the dual-shaft motor 8. The dual-shaft motor 8 and the first stirring paddle 9 can stir the liquid fertilizer inside the preheating box 2, so that the liquid fertilizer can fully contact the exhaust pipe 4 and easily absorb the heat of water vapor.

[0023] In this embodiment, a feeding pipe 3 is provided at the top center of the preheating box 2. The feeding pipe 3 is located between the two exhaust pipes 4. A drain pipe 5 is fixedly provided on one side of the bottom of the exhaust pipe 4. A valve is installed on the drain pipe 5. A discharge pipe 7 is provided at the bottom of the concentration box 1. A valve is installed on the discharge pipe 7. The liquefied water vapor can be discharged through the drain pipe 5 to avoid affecting the discharge of water vapor and the absorption of heat.

[0024] When using this rotary evaporation and concentration device, open the valve on the connecting pipe 6 to connect the concentration tank 1 and the preheating tank 2. Add liquid fertilizer into the preheating tank 2 through the feeding pipe 3, while the liquid fertilizer enters the concentration tank 1 through the connecting pipe 6. Close the valve on the connecting pipe 6 and continue adding liquid fertilizer into the preheating tank 2. Electrify the spiral resistance wire 12 and the straight resistance wire. Through the cooperation of the spiral resistance wire 12 and the straight resistance wire, the liquid fertilizer can be heated simultaneously from the inside and outside. Start the dual-shaft motor 8, which simultaneously drives the first stirring paddle 9 and the second stirring paddle 10 to rotate. This will not cause harm to the personnel and can improve the safety of the device. It is convenient to use the first stirring paddle 9 to heat the liquid fertilizer. The stirring paddle 9 and the second stirring paddle 10 respectively agitate the liquid fertilizer inside the preheating box 2 and the concentration box 1, thereby improving the heating efficiency of the liquid fertilizer. After the liquid fertilizer inside the concentration box 1 is heated, the water vapor inside it separates from the fertilizer and passes through the exhaust pipe 4. Since the exhaust pipe 4 is located inside the preheating box 2, the liquid fertilizer inside it can absorb the heat of the water vapor, avoiding direct discharge and energy waste. At the same time, preheating the liquid fertilizer can improve the evaporation and concentration efficiency of the liquid fertilizer. Finally, it is discharged through the exhaust pipe 4. The water produced by the liquefaction of water vapor gathers in the drain pipe 5 and is finally discharged through the drain pipe 5. The liquid fertilizer in the preheating box absorbs the heat from the water vapor.
