[0023] The present invention will be further described in detail below with reference to embodiments:
[0024] like Figures 1-5 As shown, this utility model provides a double-layer insulated reactor, including a connecting assembly 1, a stirring assembly 2, and a heat preservation assembly 3. The connecting assembly 1 includes an outer tank 10 and a support leg 11. The support leg 11 is fixedly installed at the bottom of the outer tank 10. An upper connecting cover 12 is provided on the top of the outer tank 10. A connecting bolt 15 is provided at the bottom of the upper connecting cover 12. A support sleeve 13 is fixedly installed on the top of the upper connecting cover 12. A liquid injection pipe 14 is provided on the top of the upper connecting cover 12. The upper and lower medium reaction tanks 22 are connected by a connecting column 16, and the upper connecting cover 12 is connected to the outer tank 10 by the connecting bolt 15.
[0025] like Figures 2-5As shown, the stirring assembly 2 is located inside the connecting assembly 1. The stirring assembly 2 includes a drive motor 20 and a stirring rod 21. The stirring rod 21 is fixedly installed at one end of the drive motor 20, and the drive motor 20 is fixedly installed at the top of the support sleeve 13. A liquid outlet pipe 23 is provided at the bottom of the medium reaction tank 22, and a connecting column 16 is provided at the top of the medium reaction tank 22. A rotating bearing 24 is provided inside the upper connecting cover 12, and the stirring rod 21 is fixedly installed inside the rotating bearing 24. A pressure plate 25 is provided inside the upper connecting cover 12, and the pressure plate 25 is located outside the stirring rod 21. A sealing ring 26 is provided at the bottom of the pressure plate 25. The sealing ring 26 is fixed to the outside of the stirring rod 21 by the pressure plate 25, sealing the connection between the stirring rod 21 and the tank body. The reaction medium is injected into the medium reaction tank 22 through the liquid injection pipe 14, and then the drive motor 20 drives the stirring rod 21 to rotate inside the medium reaction tank 22 to stir the reaction medium, so that the reaction media can be mixed evenly and the reaction time is reduced. After the reaction is completed, the medium is discharged through the liquid outlet pipe 23.
[0026] like Figures 2-5 As shown, the insulation component 3 is disposed inside the connecting component 1. The insulation component 3 includes an insulation layer 33, which is disposed inside the outer tank 10. Both the upper connecting cover 12 and the outer tank 10 are provided with insulation layers 33. A vacuum layer 31 is disposed inside the insulation layer 33, and an annular heating layer 32 is disposed inside the vacuum layer 31. A medium reaction vessel 22 is disposed inside the annular heating layer 32. A heating pipe 34 is disposed on one side of the annular heating layer 32, and a vacuum pipe 30 is disposed inside the vacuum layer 31. High-temperature medium is injected into the annular heating layer 32 through the heating pipe 34 to heat the medium reaction vessel 22. The heating pipe 34 and the annular heating layer 32 surround the outside of the medium reaction vessel 22, allowing the high-temperature medium to envelop the medium reaction vessel 22. With the combined action of the heating pipe 34 and the annular heating layer 32, the medium reaction vessel 22 is heated more evenly. Then, it is connected to an external vacuum machine through the vacuum pipe 30. The vacuum machine evacuates the vacuum layer 31, making it difficult for heat to diffuse to the outer vessel 10. The heat insulation layer 33 outside the vacuum layer 31 insulates the reaction vessel. The heat utilization rate of the medium reaction vessel 22 is improved through the vacuum layer 31 and the heat insulation layer 33. With the combined action of the vacuum pipe 30, the vacuum layer 31, and the heat insulation layer 33, heat loss is reduced, thereby reducing production costs.
[0027] The working principle of this double-insulated reactor will be explained in detail below.
[0028] like Figures 1-5As shown, when using this double-insulated reactor, the upper and lower media reaction tanks 22 are connected by connecting columns 16, and the upper connecting cover 12 is connected to the outer tank body 10 by connecting bolts 15. After the device is assembled, the reaction medium is injected into the media reaction tank 22 through the injection pipe 14, and then a high-temperature medium is injected into the annular heating layer 32 through the heating pipe 34 to heat the media reaction tank 22. By making the annular heating layer 32 surround the outside of the media reaction tank 22, the high-temperature medium envelops the media reaction tank 22. Under the combined action of the heating pipe 34 and the annular heating layer 32, the heating of the media reaction tank 22 is more uniform. The vacuum pipe 30 is connected to an external vacuum machine, which evacuates the vacuum layer 31 to prevent heat from easily diffusing to the outer tank 10. The reaction vessel is then insulated by the insulation layer 33 outside the vacuum layer 31. The heat utilization rate of the medium reaction tank 22 is improved by the vacuum layer 31 and the insulation layer 33. The heat loss is reduced by the combined action of the vacuum pipe 30, the vacuum layer 31, and the insulation layer 33, thereby reducing production costs. The drive motor 20 drives the stirring rod 21 to rotate inside the medium reaction tank 22 to stir the reaction medium, ensuring that the reaction media are mixed evenly and reducing the reaction time. After the reaction is completed, the medium is discharged through the liquid outlet pipe 23.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
