DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0020] Please refer to Figs. 1 to 4The embodiment of the application provides a low-temperature water bath device for Karl Fischer reagent, which comprises a reaction box 1, a water bath box 2 and a water storage box 3. The reaction box 1 is rotatably and sealingly installed in the water bath box 2. The top of the reaction box 1 is provided with a feeding port 4, and the bottom of the reaction box 1 is provided with a discharging port 5. The feeding port 4 and the discharging port 5 are rotatably and sealingly installed on the water bath box 2 through sealing bearings. A first rotary driving device 6 is installed on the water bath box 2. The first rotary driving device 6 can be a motor. The output end of the first rotary driving device 6 is provided with a driving gear 7. A gear ring 8 is installed on the top of the reaction box 1. The driving gear 7 is in meshing connection with the gear ring 8. A sliding groove 9 is arranged in the water storage box 3. A rack 10 is slidingly and sealingly connected in the sliding groove 9. A gear wheel 11 is rotatably connected in the sliding groove 9. The gear wheel 11 is in meshing connection with the rack 10. A sealing plate 12 is slidingly and sealingly connected in the water storage box 3. The sealing plate 12 is connected with the rack 10. The sealing plate 12 divides the water storage box 3 into a cold water chamber 13 and a warm water chamber 14. The cold water chamber 13 stores a low-temperature water source for cooling. The sealing plate 12 and the water storage box 3 are both heat-insulating materials. The cold water chamber 13 and the warm water chamber 14 are connected with the water bath box 2 through a communication pipe one 15 and a communication pipe two 16 respectively. A rotary flow guide plate 17 is installed in the water bath box 2.

[0021] In the embodiment, the material enters the reaction box 1 through the feeding port 4 on the top of the reaction box 1, and is discharged through the discharging port 5 on the bottom of the reaction box 1 after water bath reaction. The reaction box 1 is cooled by the water bath box 3 during the water bath process, so that the temperature is always kept at a low level. During the reaction, the gear wheel 11 can be driven by the motor or other driving devices, so that the rack 10 slidingly arranged in the sliding groove 9 moves up and down, thereby the sealing plate 12 gives the low-temperature water source in the cold water chamber 13 of the water storage box 3 pressure, so that the low-temperature water flow is pumped into the water bath box 2 through the communication pipe one 15, and the water source originally heated after the temperature is transmitted by the reaction box 1 in the water bath box 2 can be sucked away by the sealing plate 12 and backflow into the warm water chamber 14 through the communication pipe two 16, so that the water is simultaneously supplied and discharged, the water source can be replaced faster, and the cooling efficiency is improved. When the low-temperature water flow is sent into the water bath box 2 through the communication pipe one 15, it is guided by the rotary flow guide plate 17, so that the low-temperature water flow is quickly circulated outside the reaction box 1 under the guidance of the rotary flow guide plate 17 and the reaction box 1, and is then discharged, avoiding the defect that the low-temperature water flow is directly sucked away and discharged from one side of the reaction box 1 after entering, and the heat exchange effect of the other side of the reaction box 1. During the heat exchange, the first rotary driving device 6 drives the driving gear 7 to rotate, so that the reaction box 1 can be self-rotated in the water bath box 2 through the meshing of the driving gear 7 and the gear ring 8, thereby the water bath cooling of each part of the reaction box 1 is uniform.

[0022] In some embodiments, in order to stir the calfeizu reagent, the water bath cooling effect is better, the feeding pipe 18 is arranged on the feeding port 4 through the rotary joint, and the stirring rod 19 is arranged in the feeding pipe 18. Therefore, the material is sent into the feeding port 4 for feeding by the feeding pipe 18, and the rotating reaction box 1 cooperates with the fixed stirring rod 19 to stir the material in the reaction box 1.

[0023] In some embodiments, in order to protect the rack 10 and make the connection between the rack 10 and the sealing plate 12 stable, the number of the rack 10 is two, the two racks 10 are oppositely arranged, the pinion 20 is rotatably connected in the sliding groove 9, the pinion 20 is meshedly connected with the gear 11, and the pinion 20 and the gear 11 are meshedly connected with one of the racks 10. Therefore, the two racks 10 are driven to move by the gear 11 and the pinion 20, so that the connection between the rack 10 and the sealing plate 12 is more stable.

[0024] In some embodiments, in order to drive the gear 11 to rotate, the second rotary driving device 21 is arranged on the water storage tank 3, the second rotary driving device 21 can be a motor, and the output end of the second rotary driving device 21 is in transmission connection with the gear 11.

[0025] In some embodiments, in order to control the water storage tank 3 to output water flow in time, the valve 22 is arranged on the communication pipe one 15 and the communication pipe two 16. The valve 22 can be an electromagnetic valve, and the valve 22 and the second rotary driving device 21 should be in signal connection with the temperature sensor on the reaction box 1 through a signal processor.

[0026] In some embodiments, in order to replenish or discharge the water source in the cold water chamber 13 and the warm water chamber 14, the balance pipe 23 which is in communication with the outside is arranged in the cold water chamber 13 and the warm water chamber 14. The water source in the cold water chamber 13 and the warm water chamber 14 is replaced through the balance pipe 23, so that the water temperature is maintained.
