The stirring motor and the electric heating plate are powered on to work. The stirring motor drives the rotating shaft to rotate through a coupling, and the rotating shaft drives the stirring frame to rotate. The magnetite raw material powder inside the drying tank is stirred by the stirring frame, and the electric heating plate heats the magnetite raw material powder. The magnetite raw material powder is evenly heated inside the drying tank by the stirring of the stirring frame. The evaporated water vapor rises upward and is dissipated to the outside through an evaporation pipe. The drying tank can be thermally insulated and protected through a heat preservation sleeve, realizing the heating and drying treatment of the magnetite raw material powder and improving the processing efficiency of the utility model.

[0003] The above device has the problem of poor drying efficiency when heating the magnetite raw material powder by the electric heating plate and stirring by the stirring frame at the same time.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0024] Ferroferric oxide is a ferrite, commonly known as black iron oxide, magnetic iron, magnet, black iron oxide, etc. Because it is a magnetic black crystal, it is also called magnetic iron oxide and is generally used as a pigment and a polishing agent. During the processing and production of ferroferric oxide raw material powder, a rapid drying device for ferroferric oxide is required.

[0025] The existing device heats the ferroferric oxide raw material powder through an electric heating plate and stirs it with a stirring frame, which is likely to cause the problem of poor drying efficiency. The main reason is that the stirring range of the stirring frame is limited, which will cause the raw material powder to fail to be effectively and evenly mixed and heat transferred during the heating process. This will result in some areas having too high or too low temperatures, as well as inconsistent drying speeds, affecting the overall drying efficiency and quality of the ferroferric oxide raw material powder. Please refer to Figures 1 - 4 , the embodiment provides a rapid drying device for ferroferric oxide, including a drying tank 1, and a feed pipe 11, a discharge pipe 12, and an exhaust pipe 13 are fixedly communicated with the drying tank 1.

[0026] Refer to Figures 2 - 4 As shown, an annular heating plate 2 is fixedly connected to the inner wall of the drying tank 1, which can increase the heating surface area and the heat conduction efficiency, and can heat the ferroferric oxide raw material powder more evenly, thereby quickly removing moisture from the material. Plate-shaped heating plates 21 are fixedly connected to the inner walls of several stirring blades 345. They can not only heat the ferroferric oxide raw material powder, but also evenly distribute heat through stirring and mixing, preventing the problems of adhesion or uneven heat of the ferroferric oxide raw material powder, and ensuring the drying effect and quality of the ferroferric oxide raw material powder.

[0027] Reference Figures 2 - 4 As shown, in the existing device, when the raw material powder of iron tetroxide is heated by an electric heating plate and the stirring frame is used for stirring at the same time, it is easy to cause the problem of poor drying efficiency. The main reason is that the stirring range of the stirring frame is limited, which will cause the raw material powder not to be effectively and evenly mixed and heat transferred during the heating process. This will lead to too high or too low temperature in some areas, as well as the inconsistency of the drying speed, affecting the overall drying efficiency and quality of the raw material powder of iron tetroxide. In order to improve the overall drying efficiency and quality of the raw material powder of iron tetroxide, the following settings are made specifically. A drying mechanism 3 for quickly drying the raw material powder of iron tetroxide is provided at the top of the drying tank 1. The drying mechanism 3 includes a motor 31 fixed to the top of the drying tank 1. The output end of the motor 31 is fixedly connected with a rotating shaft 32. The outer wall of the middle end of the rotating shaft 32 is fixedly connected with a hole cylinder 33. Start the motor 31 to drive the rotating shaft 32 to rotate at the output end. The rotation of the rotating shaft 32 drives the hole cylinder 33 to rotate. Pour the raw material powder of iron tetroxide into the drying tank 1 from the feed pipe 11 and drop it into the hole cylinder 33. The raw material powder of iron tetroxide will be thrown out of the holes of the hole cylinder 33 by the action of centrifugal force and dried under the hot temperature.

[0028] On both sides of the peripheral surface of the hole cylinder 33, two groups of heat - equalizing components 34 for surrounding and rotating to stir the raw material powder of iron tetroxide are symmetrically arranged under the synchronous driving of the hole cylinder 33. The heat - equalizing component 34 includes a connecting plate 341 fixed to the peripheral surface of the top end of the hole cylinder 33. The inner wall of the connecting plate 341 is rotatably connected with a rotating rod 342. The outer wall of the top end of the rotating rod 342 is fixedly connected with a gear 343. The inner top wall of the drying tank 1 is fixedly connected with a tooth ring 344 meshing with the gear 343. The outer wall of the rotating rod 342 is fixedly connected with a number of stirring blades 345. The number of stirring blades 345 rotates around the core of the drying tank 1. The rotation of the hole cylinder 33 makes the gear 343 mesh with the tooth ring 344 to drive the rotating rod 342 to rotate around, so that the number of stirring blades 345 rotates around the core of the drying tank 1. In this way, the raw material powder of iron tetroxide thrown out of the holes of the hole cylinder 33 is stirred. The outer wall of the rotating shaft 32 is fixedly connected with a number of stirring blades 345. The number of stirring blades 345 rotates in place around the core of the drying tank 1. When the raw material powder of iron tetroxide falls to the bottom of the drying tank 1, the number of stirring blades 345 rotates under the drive of the rotating shaft 32 to stir and dry the accumulated raw material powder of iron tetroxide again, further improving the overall drying efficiency and quality of the raw material powder of iron tetroxide.

[0029] Reference Figures 3 - 4As shown, on one side of several stirring blades 345, there is fixedly connected a crushing cone head 3451 for crushing the agglomerated ferroferric oxide raw material powder. The arrangement of the crushing cone heads 3451 on the material-facing surfaces of several stirring blades 354 can effectively break up the agglomerates of the ferroferric oxide raw material powder, enabling the raw material powder to be more evenly exposed on the heating surface, thereby improving the drying efficiency. Moreover, by promptly crushing the agglomerates, the drying time and energy consumption of the ferroferric oxide raw material powder can be reduced, the production efficiency of the ferroferric oxide raw material powder can be increased, and the quality can be ensured.

[0030] Reference Figure 4 As shown, on the side of several stirring blades 345 away from the crushing cone head 3451, there is fixedly connected a reinforcing plate 3452 that is fixedly connected to the circumferential surface of the rotating rod 342. The reinforcing plate 3452 is made of steel plate. When several stirring blades 345 rotate inside the drying tank 1, they will be affected by the resistance and inertial force of the powder. Especially when the viscosity of the powder is relatively large or the agglomeration phenomenon is relatively serious, the reinforcing plate 3452 can effectively increase the overall structural strength of the stirring blade 345 and reduce the risk of the blade bending or breaking due to external forces.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
