[0026] Example

[0027] The existing potassium nitrate reactor is heated by arranging a heating tube outside the reactor to achieve heating, which results in uneven heating of the potassium nitrate inside the reactor during preparation, thereby reducing the efficiency of potassium nitrate preparation.

[0028] In order to solve the above technical problems, refer to Figure 1 , Figure 2 and Figure 3 The present embodiment provides a reactor for preparing potassium nitrate, including a mounting frame 1, a reactor body 2, a rotating shaft 6, a first spiral blade 3, a second spiral blade 4 and a coaxial reverse drive assembly 5. The reactor body 2 is rotatably connected to the mounting frame 1, and a feed port 21 and a discharge port 22 are provided on the reactor body 2, wherein a closable valve may be provided at the discharge port 22. The rotating shaft 6 is rotatably connected to the reactor body 2, one end of the rotating shaft 6 is located in the reactor body 2, and the other end passes through the bottom of the reactor body 2. The first spiral blade 3 is mounted on the inner side wall of the reactor body 2. The second spiral blade 4 is mounted on the outer side wall of the rotating shaft 6 and is located in the reactor body 2, and electric heating wires are provided inside the first spiral blade 3 and the second spiral blade 4. The coaxial reverse drive assembly 5 is mounted on the mounting frame 1, and the coaxial reverse drive assembly 5 is transmission-connected with the reactor body 2 and the rotating shaft 6 to drive the reactor body 2 and the rotating shaft 6 to rotate coaxially in the opposite direction. A sealing gasket may be installed at the connection between the rotating shaft 6 and the bottom of the reactor body 2 to prevent the raw materials from leaking out. Figure 3 and Figure 5 As shown, the first spiral blade 3 and the second spiral blade 4 have the same rotation direction.

[0029] Through the above structure, the present embodiment provides a reactor for preparing potassium nitrate. When in use, the raw materials required for the preparation are first poured into the reactor body 2 through the feed port 21, and the rotating shaft 6 and the reactor body 2 are driven to rotate by the coaxial reverse drive component 5, so that the first spiral blade 3 and the second spiral blade 4 rotate along the circumferential direction of the rotating shaft 6, and the rotation direction of the first spiral blade 3 relative to the rotating shaft 6 is opposite to the rotation direction of the second spiral blade 4 relative to the rotating shaft 6. At the same time, since electric heating wires are arranged inside the first spiral blade 3 and the second spiral blade 4, the prepared raw materials flow in the reactor body 2 as the first spiral blade 3 and the second spiral blade 4 rotate, so that the raw materials inside the reactor body 2 are heated more evenly and mixed more evenly, thereby solving the technical problem that the existing potassium nitrate reactor is heated unevenly during potassium nitrate preparation, thereby reducing the efficiency of potassium nitrate preparation.

[0030] On the basis of the above, in order to facilitate the driving of the rotating shaft 6 and the reactor body 2 to rotate coaxially and in opposite directions, refer to Figure 3 , Figure 4 and Figure 5 As shown, the coaxial reverse drive assembly 5 includes a motor 7, a first gear 8, a second gear 9 and a third gear 10. The motor 7 is mounted on the mounting frame 1. The first gear 8 is mounted on the output shaft of the motor 7. The second gear 9 is mounted on the rotating shaft 6, and the second gear 9 is meshed with the first gear 8. The mounting frame 1 has a through hole, and the reactor body 2 has a connecting end, the connecting end passes through the through hole, and the third gear 10 is mounted on the connecting end and meshed with the first gear 8, wherein the diameter of the cross section at the connecting end of the reactor body 2 is greater than the diameter of the rotating shaft 6. It should be specifically explained that the connecting end of the above-mentioned reactor body 2 can also be a connecting shaft, one end of the connecting shaft is connected to the bottom of the reactor body 2, and the other end passes through the through hole, the third gear 10 can be mounted on the other end of the connecting shaft, and meshed with the first gear 8, and the diameter of the cross section of the connecting shaft is greater than the diameter of the cross section of the rotating shaft 6. The output shaft of the motor 7 rotates to rotate the first gear 8 and drive the second gear 9 and the third gear 10 to rotate, thereby causing the rotating shaft 6 and the reactor body 2 to rotate in opposite directions. Since the first spiral blade 3 and the second spiral blade 4 have the same rotation direction, the raw materials for preparing potassium nitrate flow in the reactor body 2.

[0031] On the basis of the above, in order to facilitate the installation of the reactor body 2, refer to Figure 6 and Figure 7 As shown, a groove 11 is provided on the mounting frame 1, and a pulley 12 is rotatably mounted in the groove 11. The bottom of the reactor body 2 has a limiting groove 13 corresponding to the groove 11. A part of the pulley 12 is located in the limiting groove 13, so that the reactor body 2 can rotate relative to the mounting frame 1.

[0032] On the basis of the above, in order to facilitate the installation of the motor 7, refer to Figure 5 As shown, the mounting frame 1 further comprises a fixing plate 14. The fixing plate 14 is mounted on the mounting frame 1, and the motor 7 is mounted on the fixing plate 14.

[0033] On the basis of the above, refer to Figure 5 As shown, a reactor for preparing potassium nitrate further includes an end cover 15. The end cover 15 is installed at the feed port 21 of the reactor body 2. The potassium nitrate preparation raw material is placed into the reactor body 2 by opening the end cover 15. Since a closable valve is provided at the discharge port 22, it is only necessary to close the valve during the preparation process. After the preparation is completed, a pipeline can be connected to the valve and the valve can be opened to take out the potassium nitrate solution.

[0034] In summary, in the use of a reactor for preparing potassium nitrate, the end cover 15 is first opened to pour the raw materials for preparing potassium nitrate into the reactor body 2. After closing the end cover 15, the motor 7 is turned on to rotate the output end of the motor 7 so that the first gear 8 rotates and drives the second gear 9 and the third gear 10 to rotate, thereby causing the rotating shaft 6 and the reactor body 2 to rotate in opposite directions, and the direction in which the first spiral blade 3 rotates relative to the rotating shaft 6 is opposite to the direction in which the second spiral blade 4 rotates relative to the rotating shaft 6. At the same time, since electric heating wires are provided inside the first spiral blade 3 and the second spiral blade 4, the prepared raw materials flow in the reactor body 2 as the first spiral blade 3 and the second spiral blade 4 rotate, so that the raw materials inside the reactor body 2 are heated more evenly and mixed more evenly, thereby solving the technical problem that the existing potassium nitrate reactor is unevenly heated during potassium nitrate preparation, thereby reducing the efficiency of potassium nitrate preparation.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
