Description

Technical Field

[0001] This utility model relates to the field of manganese tetroxide preparation technology, specifically to a manganese tetroxide preparation device. Background Technology

[0002] Manganese tetroxide (Mn3O4) is an important chemical substance. There are various methods for preparing manganese tetroxide, including reduction method, mixed calcination method, solution precipitation oxidation method, metallic manganese method, high-valence manganese oxidation method and manganese carbonate method.

[0003] By using a mixed calcination method, manganese oxides, hydroxides, sulfates, or carbonates are calcined in air or oxygen at approximately 1000°C to readily generate manganese tetroxide. Existing manganese tetroxide calcination reactors achieve calcination by injecting oxygen into the reactor. However, the oxygen injected into the reactor cannot be fully mixed into the manganese oxide, resulting in low calcination efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a manganese tetroxide preparation apparatus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a manganese tetroxide preparation device, comprising a reaction vessel, an inlet pipe fixedly connected to the upper interior of the reaction vessel, a connecting pipe rotatably connected to the lower inner side of the inlet pipe, a rotating disk communicating with the connecting pipe fixedly connected to the lower part of the connecting pipe, a plurality of air outlet holes opened on the upper part of the rotating disk, a plurality of stirring blades fixedly connected to the outer side of the rotating disk, a gear ring fixedly connected to the upper outer side of the connecting pipe, a connecting gear meshing with the outer side of the gear ring, a rotating shaft fixedly connected to the tail of the connecting gear, a lower bevel gear fixedly connected to the upper part of the rotating shaft penetrating the reaction vessel, an upper bevel gear meshing with the upper part of the lower bevel gear, a motor fixedly connected to the tail of the upper bevel gear, and the motor fixedly connected to the upper part of the reaction vessel.

[0006] Preferably, an installation ring is fixedly connected inside the rotating disk, and a filter screen is provided between the upper part of the installation ring and the inner wall of the rotating disk.

[0007] Preferably, a connecting groove is provided on the inner side of the upper part of the reactor, and a rotating groove communicating with the connecting groove is provided on the inner side of the upper part of the reactor. Connecting frames are fixedly connected to both sides of the upper part of the connecting pipe, and a rotating plate is fixedly connected to the upper part of the connecting frame through the connecting groove. The rotating plate is rotatably connected to the inside of the rotating groove.

[0008] Preferably, a feed pipe is fixedly connected to the upper part of the reactor, a filter table is fixedly connected to the upper part of the reactor, a mounting base is fixedly connected to the outer side of the upper part of the connecting pipe, a mounting frame is fixedly connected to one side of the mounting base, and a rolling wheel is rotatably connected inside the mounting frame.

[0009] Preferably, the upper part of the filter table is configured with a high perimeter and a low center, and the rolling wheel is in close contact with the upper part of the filter table.

[0010] Preferably, a ramp is fixedly connected to the lower part of the reactor, and a discharge pipe is fixedly connected to the lower part of the ramp.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a motor to drive an upper bevel gear, which in turn drives a connecting gear to rotate. The gear ring drives the connecting pipe to rotate. Oxygen enters through the inlet pipe, passes through the connecting pipe into the rotating disk, and then exits through the outlet hole. This allows the oxygen to be evenly dispersed inside the manganese oxide. The rotation of the rotating disk stirs the manganese oxide in the reactor with stirring blades, accelerating the mixing with oxygen and making it easier for oxygen to be more evenly dispersed inside the manganese compound. The stirring also accelerates the reaction between the manganese compound and oxygen, thus improving production efficiency.

[0013] 2. This utility model also enables the rolling wheel to rotate via the mounting base and mounting frame when the connecting pipe rotates. The rolling wheel itself rotates to crush the manganese oxides on the upper part of the filter table, which facilitates the decomposition of manganese oxides into fine particles that fall from the filter table, thus pre-treating the manganese compounds and preventing the manganese compounds from being too large to be conducive to calcination.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a manganese tetroxide preparation device, including a reaction vessel 1. An inlet pipe 2 is fixedly welded to the upper inner side of the reaction vessel 1. A connecting pipe 3 is rotatably installed on the lower inner side of the inlet pipe 2. A rotating disk 4 communicating with the connecting pipe 3 is fixedly welded to the lower part of the connecting pipe 3. Several sets of outlet holes 6 are opened on the upper part of the rotating disk 4. Oxygen enters through the inlet pipe 2, passes through the connecting pipe 3 into the interior of the rotating disk 4, and is then discharged through the outlet holes 6, so that the oxygen is evenly dispersed inside the manganese oxide. Several sets of stirring blades 5 are fixedly welded to the outer side of the rotating disk 4. The rotation of the rotating disk 4, through the stirring blades 5, stirs the contents of the reaction vessel 1. Manganese oxide is stirred to accelerate mixing with oxygen. A gear ring 9 is fixedly welded to the outer side of the upper part of the connecting pipe 3. A connecting gear 10 is meshed with the outer side of the gear ring 9. A rotating shaft 11 is fixedly welded to the tail of the connecting gear 10. A lower bevel gear 12 is fixedly welded to the upper part of the rotating shaft 11, penetrating the reactor 1. An upper bevel gear 13 is meshed with the upper part of the lower bevel gear 12. A motor 14 is connected to the tail of the upper bevel gear 13 via a coupling. The flange of the motor 14 is installed on the upper part of the reactor 1. The motor 14 drives the upper bevel gear 13 to drive the connecting gear 10 to rotate through the lower bevel gear 12, and drives the connecting pipe 3 to rotate through the gear ring 9.

[0021] A mounting ring 7 is fixedly welded inside the rotating disk 4. A filter screen 8 is installed between the upper part of the mounting ring 7 and the inner wall of the rotating disk 4 to prevent manganese oxides from entering the interior of the rotating disk 4. A connecting groove 19 is opened on the inner side of the upper part of the reactor 1. A rotating groove 20 communicating with the connecting groove 19 is opened on the inner side of the upper part of the reactor 1. A connecting frame 21 is fixedly welded to both sides of the upper part of the connecting pipe 3. A rotating plate 22 is fixedly welded to the upper part of the connecting frame 21 through the connecting groove 19. The rotating plate 22 is rotatably connected to the interior of the rotating groove 20 to support the connecting pipe 3. A feed pipe 15 is fixedly welded to the upper part of the reactor 1. A filter table 16 is fixedly welded to the upper part of the reactor 1. A mounting base 23 is fixedly welded to the outer side of the upper part of the connecting pipe 3. A mounting base 23 is fixedly welded to one side of the mounting base 23. There is a mounting bracket 24, and a crushing wheel 25 is rotatably connected inside the mounting bracket 24. Manganese oxide enters the filter table 16 through the feed pipe 15. When the connecting pipe 3 rotates, it drives the crushing wheel 25 to rotate through the mounting base 23 and the mounting bracket 24. The crushing wheel 25 rotates itself to crush the manganese oxide on the upper part of the filter table 16, so that the manganese oxide is decomposed into fine particles and falls off the filter table 16. The upper part of the filter table 16 is designed with a high perimeter and a low center. The crushing wheel 25 is close to the upper part of the filter table 16, so that the manganese oxide can be scattered on the filter table 16 over a larger area. A ramp 17 is fixedly welded to the lower part of the reactor 1, and a discharge pipe 18 is fixedly welded to the lower part of the ramp 17, so that the reacted manganese tetroxide can be discharged through the discharge pipe 18.

[0022] Working principle: In use, manganese oxide enters the filter table 16 through the feed pipe 15. The motor 14 drives the upper bevel gear 13 to rotate through the lower bevel gear 12, which in turn drives the connecting gear 10 to rotate. The gear ring 9 drives the connecting pipe 3 to rotate. When the connecting pipe 3 rotates, it drives the rolling wheel 25 to rotate through the mounting base 23 and the mounting bracket 24. The rolling wheel 25 rotates itself to crush the manganese oxide on the upper part of the filter table 16, making it easier for the manganese oxide to decompose into fine particles that fall from the filter table 16. Oxygen enters through the air inlet pipe 2, enters the interior of the rotating disk 4 through the connecting pipe 3, and is then discharged through the air outlet 6, so that the oxygen is evenly dispersed inside the manganese oxide. The rotation of the rotating disk 4 stirs the manganese oxide in the reaction vessel 1 through the stirring blade 5, accelerating the mixing with oxygen.
