This fixing method has unstable connection, and the evaporation flask is easy to fall off the evaporator and be damaged during rotation. In severe cases, the evaporation flask will be broken. Therefore, we provide a protective device for a rotary evaporator to solve the above problems. Content of the Utility Model

[0026] The embodiment of the present utility model provides a protective device for a rotary evaporator.

[0027] Please refer to Figure 1 , which includes a working platform 1. A rotary evaporator 2 is fixedly installed on the top surface of the working platform 1. An evaporation flask 4 is arranged at one end of the rotary evaporator 2. The rotary evaporator 2, evaporation pot 5, condenser 9, bidirectional screw 302 and micro motor involved in this application are all prior arts, and will not be elaborated too much in this application. The rotary evaporator 2 can rotate according to the actual situation to adjust the angle of the evaporation flask 4, so that part of the evaporation flask 4 is located below the water surface inside the evaporation pot 5. At the same time, the rotary evaporator 2 can also drive the evaporation flask 4 to rotate, so that the solution inside the clamping mechanism 3 evaporates evenly and fully.

[0028] Please refer to Figure 1 and Figure 2 On the top surface of the working platform 1, an evaporation pan 5 is fixedly connected. On the top surface of the evaporation pan 5, a main protective cover 6 is fixedly connected. Inside the main protective cover 6, an auxiliary protective cover 7 is slidably connected. When the water inside the evaporation pan 5 is heated, the solution inside the evaporation flask 4 can be heated up for distillation. Through the settings of the main protective cover 6 and the auxiliary protective cover 7, the inside of the evaporation pan 5 can be protected to prevent hot water from splashing outside the evaporation pan 5 and causing harm to the staff or other equipment. At the same time, it can also prevent water vapor from floating upwards into the laboratory and falling on the surface of the equipment and the laboratory walls, thus causing the surface of the equipment to rust and pollute the laboratory environment, increasing the difficulty of cleaning for the staff and causing waste of water resources.

[0029] On the outer surfaces of the main protective cover 6 and the auxiliary protective cover 7, empty slots adapted to the evaporation flask 4 are provided. Through the setting of the empty slots, it is convenient to place the evaporation flask 4 into the evaporation pan 5 for distillation or take out the evaporation flask 4 from the evaporation pan 5. The size of the empty slots is determined by the caliber of the evaporation flask 4 to ensure that it will not affect the rotation of the evaporation flask 4. Magnets are fixedly installed at specific positions of the evaporation pan 5, the main protective cover 6, and the auxiliary protective cover 7. Through the magnets, the auxiliary protective cover 7 can be fixed on the evaporation pan 5 or the main protective cover 6 to prevent the auxiliary protective cover 7 from sliding inside the main protective cover 6 by itself. A handle is installed on the outer surface of the auxiliary protective cover 7 to facilitate the staff to pull out or retract the auxiliary protective cover 7 from the main protective cover 6. The width of the magnet is greater than the width of the handle. When the magnets are attracted together, the handle will not affect the closing of the auxiliary protective cover 7.

[0030] On the top surface of the working platform 1, a support frame 8 is fixedly connected. Inside the support frame 8, a condenser 9 is fixedly connected. The two ends of the condenser 9 are respectively fixedly communicated with the main protective cover 6 and the evaporation pan 5 through condensing pipes. The water vapor generated by the distillation of the evaporation pan 5 can flow into the condenser 9 through the condensing pipe on the top surface of the main protective cover 6 for condensation. The condensed water will flow back into the evaporation pan 5 again through the water pipe at the bottom end of the condenser 9, realizing the recycling of water resources and reducing the waste of water resources.

[0031] Please refer to Figure 1 and Figure 3, a damping telescopic rod 10 is fixedly connected to the top surface of the working platform 1. The top surface of the damping telescopic rod 10 is fixedly connected to a bearing platform 11. A support spring 12 is sleeved on the outer surface of the damping telescopic rod 10. The two ends of the support spring 12 are respectively fixedly connected to the working platform 1 and the bearing platform 11. Above the bearing platform 11, a collection volumetric flask 13 is arranged. The bearing platform 11 can bear the collection volumetric flask 13, so that the collection volumetric flask 13 can remain stable when collecting the distilled gas inside the recovery evaporation flask 4. The damping telescopic rod 10 has a large damping coefficient, which can neutralize the slight shaking generated by the support spring 12, and avoid the shaking of the support spring 12 due to its own material, which affects the collection operation of the collection volumetric flask 13. Through the setting of the support spring 12 and the damping telescopic rod 10, it is convenient for the staff to install the collection volumetric flask 13 on the rotary evaporator 2 or remove the collection volumetric flask 13 from the rotary evaporator 2.

[0032] Please refer to Figure 1 and Figure 4 , a clamping mechanism 3 is arranged at the end of the rotary evaporator 2. The clamping mechanism 3 includes a clamping box 301. The clamping box 301 is fixedly connected to the rotary evaporator 2. A bidirectional screw rod 302 is rotatably connected inside the clamping box 301. A micro motor is fixedly installed outside the clamping box 301. The bidirectional screw rod 302 penetrates through the clamping box 301 and is fixedly connected to the output rotating shaft of the micro motor. When the micro motor starts, it can drive the bidirectional screw rod 302 to rotate. When the bidirectional screw rod 302 rotates, it can drive the clamping slider 303 to slide inside the clamping box 301. When the rotary evaporator 2 drives the evaporation flask 4 to rotate, the end of the rotary evaporator 2 will drive the clamping box 301 to rotate, so that the clamping claws 304 can maintain the clamping state of the evaporation flask 4.

[0033] A support rod 305 is fixedly connected inside the clamping box 301. The support rod 305 is slidably connected to the clamping slider 303. The support rod 305 can provide support for the sliding of the clamping slider 303, so that the clamping slider 303 can remain stable during the sliding process, and avoid the clamping slider 303 sliding off the track and affecting the clamping effect of the clamping claws 304.

[0034] The clamping slider 303 is threadedly connected to the outer surface of the bidirectional screw rod 302. The clamping slider 303 is slidably connected to the clamping box 301. The threads of the bidirectional screw rod 302 are opposite. When the bidirectional screw rod 302 rotates, it can drive the two clamping sliders 303 to approach or move away from each other inside the clamping box 301, so as to drive the two clamping claws 304 to clamp the evaporation flask 4, making the device applicable to evaporation flasks 4 with various different diameters.

[0035] The outer surface of the clamping slider 303 is fixedly connected with a clamping claw 304, and the outer surface of the clamping claw 304 is fixedly connected with a rubber soft pad 306. The rubber soft pad 306 can increase the friction between the clamping claw 304 and the evaporation flask 4, enabling the clamping claw 304 to stably clamp the evaporation flask 4. At the same time, the rubber soft pad 306 also provides buffering for the clamping operation of the clamping claw 304, preventing the evaporation flask 4 from being damaged during the clamping process.

[0036] Working principle: When the staff wants to perform rotary evaporation on the solution inside the evaporation flask 4, first adjust the angle of the rotary evaporator 2 and install the collecting flask 13 at the designated position. Then place the evaporation flask 4 at the end of the rotary evaporator 2. Start the micro-motor, and the rotation of the motor drives the bidirectional screw 302 to rotate. The rotation of the bidirectional screw 302 drives the two clamping sliders 303 to slide towards each other inside the clamping box 301, thereby driving the two clamping claws 304 to approach each other and finally clamp the evaporation flask 4, ensuring that the evaporation flask 4 is fixed at the end of the rotary evaporator 2. Then pull down the auxiliary protective cover 7 and start the rotary evaporator 2 and the evaporation pan 5. At this time, the device will perform rotary evaporation on the evaporation flask 4, preventing the evaporation flask 4 from falling off the end of the rotary evaporator 2 during the rotary evaporation process and ensuring the safe progress of the evaporation operation of the device.
