DETAILED DESCRIPTION

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0027] like Figures 1 to 5 As shown, a high-efficiency and energy-saving stainless steel reactor specifically includes a mounting frame 1, a reactor 2, a bracket 3, a frequency converter 4, a motor 5, a stirring paddle 6, an inner guide plate 7 and an outer guide plate 8;

[0028] The mounting frame 1 is provided with a reactor 2, the bottom and side of the reactor 2 are double-layered reactor walls connected to the top reactor wall, and a vacuum layer is provided between the double-layered reactor walls to ensure a sealed reaction of the reactants;

[0029] Among them, the top of the reactor 2 is provided with a bracket 3, the top of the bracket 3 is provided with a frequency converter 4, the top of the bracket 3 is provided with a motor 5, the motor 5 and the frequency converter 4 are connected by a wire, and a stirring paddle 6 is rotatably provided at the bottom of the reactor 2. The output shaft of the motor 5 is connected to the stirring paddle 6 through a coupling for stirring and mixing the reactants;

[0030] Among them, the stirring paddle 6 has two layers, the upper and lower layers, and the structure of the blades can make the reaction liquid in the reactor 2 move in a specific flow direction. The side of the middle connecting column of the stirring paddle 6 is provided with an inner guide plate 7 that can make the reaction liquid flow outward, and the outer side of the stirring paddle 6 blade is provided with an outer guide plate 8 that can make the reaction liquid flow inward, which is used to intensify the collision of reactants in the reaction liquid.

[0031] For example, when in use, the frequency converter 4 controls the power start of the motor 5, so that the motor 5 can increase the power appropriately at the beginning of the reaction and reduce the power appropriately when the reaction is stable. In this way, a portion of energy consumption can be saved without affecting the reaction rate. As the motor 5 starts, the stirring paddle 6 begins to rotate. The stirring paddle 6 is divided into two parts, the upper and lower parts, which are symmetrical along the middle horizontal axis. The outer side and bottom of the lower stirring paddle 6 are in contact with the inner wall of the reactor 2, the outer side of the front extends outward, and the inner side of the front shrinks backward. At the same time, the top front shrinks backward and the bottom front extends forward; the inner guide plate 7 and the outer guide plate 8 rotate as the stirring paddle 6 rotates. The outer side of the inner guide plate 7 extends backward and the inner side extends forward. The inner side of the outer guide plate 8 extends backward and the outer side extends forward and is in sliding contact with the inner wall of the reactor 2. In this way, during the rotation of the stirring paddle 6, the liquid on the outside is pushed inward by the stirring paddle 6, the liquid at the bottom and top is pushed to gather towards the middle by the stirring paddle 6, the liquid on the inside is pushed outward by the inner guide plate 7, and the liquid on the outside is pushed inward by the outer guide plate 8, the collision of reactants in the reaction liquid is intensified, and the reaction rate is increased. Example

[0032] like Figures 6 to 9 As shown, based on Example 1, it specifically includes a heat exchange mechanism 9, which includes a rotating disk 901, a conduit 902, a temperature sensor 903, a rectifying tank 904, a sealing plate 905, a liquid inlet pipe 906, a liquid pump 907, a heat exchanger 908, a connecting pipe 909 and a liquid outlet pipe 910. A rotating disk 901 is provided on the upper part of the central axis of the stirring paddle 6. The rotating disk 901 passes through the top wall of the reactor 2. Two conduits 902 are symmetrically distributed on the rotating disk 901 and pass through the upper and lower sides of the rotating disk 901. One end of the conduit 902 in the reactor 2 extends to the middle of the reactor 2. A temperature sensor 903 is provided on the side of the pipe opening of the conduit 902 of the rotating disk 901 on one side of the reactor 2. An annular rectifying tank 904 is provided on the top of the reactor 2. An annular sealing The sealing plate 905 forms a closed space with the rectifying tank 904, and the sealing plate 905 is in sliding contact with the rectifying tank 904. The pipe opening of the conduit 902 of the rotating disk 901 on the outside of the reactor 2 passes through the sealing plate 905 and extends into the rectifying tank 904. A liquid inlet pipe 906 is provided on the side of the rectifying tank 904, and the liquid inlet pipe 906 passes through one side of the rectifying tank 904. A liquid pump 907 is provided on the top of the reactor 2, and the liquid inlet of the liquid pump 907 is connected to the side of the liquid inlet pipe 906 outside the rectifying tank 904. A heat exchanger 908 is provided on the side of the reactor 2, and the liquid inlet of the heat exchanger 908 is connected to the liquid outlet of the liquid pump 907 through a connecting pipe 909. A liquid outlet pipe 910 is provided at the liquid outlet of the heat exchanger 908, and the end of the liquid outlet pipe 910 not connected to the heat exchanger 908 passes through the double-layer reactor wall on the side of the reactor 2 and extends into the reactor 2.

[0033] While the impeller 6 is stirring, the heat exchange mechanism 9 begins operating. Driven by the output shaft of the motor 5, the rotating disk 901 begins to rotate. The conduit 902 of the rotating disk 901 drives the sealing plate 905, which simultaneously maintains a sealed space with the rectifying tank 904 affixed to the top of the reactor 2. The liquid pump 907 is activated, and the end of the rotating disk 901 inside the reactor 2 begins to draw liquid from the reactor 2 into the rectifying tank 904. Once in the rectifying tank 904, the reaction liquid passes through the liquid inlet 906, the air pump, and the connecting pipe 909, ultimately entering the heat exchanger 908. The heat exchanger 908 is equipped with multiple spiral pipes. After entering the spiral pipes, the reaction liquid enters the lower inlet of the heat exchanger 908 and is discharged through the upper outlet of the heat exchanger 908. Heat is exchanged between the reaction liquid and the heat exchange liquid within the spiral pipes. After the heat exchange is complete, the reaction liquid returns to the reactor 2 through the liquid outlet 910. In this way, the reaction liquid in the area of ​​the reactor 2 where the reaction is most intense and the temperature change is greatest can be heat exchanged without affecting the operation of the stirring paddle 6 and the guide plate, thereby increasing the reaction rate.

[0034] like Figure 10 and Figure 11 As shown, on the basis of Example 1, it specifically includes a balancing mechanism 10, which includes a pressure sensor 1001, an electric-controlled valve 1002 and a gas tank 1003. The pressure sensor 1001 is provided at the bottom of the rotating disk 901 in the reactor 2, and the electric-controlled valve 1002 is provided on the top of the rotating disk 901. The air inlet of the electric-controlled valve 1002 passes through the rotating disk 901 and extends into the reactor 2. The pressure sensor 1001 and the electric-controlled valve 1002 are connected by a wire passing through the rotating disk 901. The gas tank 1003 is provided on the top of the rotating disk 901, and the gas tank 1003 is connected to the air outlet of the electric-controlled valve 1002.

[0035] During the entire process, balancing mechanism 10 remains engaged. Pressure sensor 1001 detects changes in air pressure within reactor 2. When the air pressure within reactor 2 becomes excessive, pressure sensor 1001 transmits a signal via wires to electronically controlled valve 1002, which opens. Gas within reactor 2 passes through electronically controlled valve 1002 and enters gas storage tank 1003, which contains various organic and inorganic solvents and can promptly absorb any incoming gas. This ensures that the air pressure within reactor 2 remains within a stable range during the reaction, ensuring both environmental and personnel safety while also accelerating the reaction rate.

[0036] like Figure 2 and Figure 12 As shown, based on Example 1, it further includes a limiting protrusion 12. The outer wall of the reactor 2 is provided with multiple limiting protrusions 12, and the limiting protrusions 12 are slidably matched with the support beams of the side walls of the mounting frame 1.

[0037] During the stirring process, as the motor 5 rotates, it not only drives the stirring paddle 6 to rotate, but also transmits a reverse torque to the reactor 2 through the bracket 3. The limiting protrusion 12 cooperates with the mounting bracket 1 to limit the horizontal rotation freedom of the reactor 2, thereby offsetting the torque transmitted to the reactor 2 by the motor 5, ensuring the smooth progress of the stirring process in the reactor 2, and indirectly improving the reaction rate.

[0038] like Figure 2 As shown, based on the embodiment 1, it further includes an elastic member 11 . A plurality of elastic members 11 are provided on the bottom of the mounting frame 1 , and the elastic members 11 are in contact with the reactor 2 .

[0039] During the entire process, the vibration generated by the operation of the reactor 2 is buffered and absorbed by the elastic member 11 , thereby avoiding the possibility of collision and rupture of the reactor 2 and ensuring the safety of the environment and personnel.

[0040] Although the present disclosure has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
