[0002] Sodium bromate, as an important chemical raw material, has wide applications in many fields. Traditional methods for drying sodium bromate typically employ a double-cone dryer. However, in conventional double-cone dryers, the material is often simply agitated by the tumbling of the double cones during the drying process. This can easily lead to excessive material concentration during heating and agitation, resulting in poor mixing and low processing efficiency, as well as insufficient drying uniformity, ultimately affecting production efficiency and product quality. Therefore, developing a novel double-cone dryer for sodium bromate production is of significant practical importance.

The double-cone drying cylinder 3 is fixedly installed on the hollow shaft 2. The shell 4 is fixedly installed inside the double-cone drying cylinder 3. Multiple stirring shafts 43 are rotatably installed on the shell 4. The multiple stirring shafts 43 are arranged radially around the axis of the hollow shaft 2. Multiple stirring rods 44 are radially fixedly installed on each of the multiple stirring shafts 43, which can perform a stirring operation on the sodium bromate raw material in the double-cone drying cylinder 3 when the stirring shafts 43 rotate. A rotating shaft 41 is fixedly installed on the support frame 1. The rotating shaft 41 is located on the same axis as the hollow shaft 2. One end of the rotating shaft 41 extends into the shell 4 and is fixedly fitted with a bevel gear 42. The ends of the multiple stirring shafts 43 that are close to each other are fixedly fitted with bevel gears 45. Each bevel gear 45 meshes with bevel gear 42, enabling multiple stirring shafts 43 to rotate under the cooperation of shaft 41, bevel gear 42, and bevel gear 45 when the double cone drying cylinder 3 rotates. It also maintains rotation around shaft 41. A motor 22 is fixedly installed on the side wall of the support frame 1. A drive gear 23 and a driven gear 21 are fixedly fitted onto the output shaft and hollow shaft 2 of the motor 22, respectively. The drive gear 23 and driven gear 21 mesh, driving the double cone drying cylinder 3 to rotate. A vacuum pump 5 is fixedly installed on the side wall of the support frame 1. The inlet of the vacuum pump 5 is connected to a hollow ring 51 fixedly connected to the side wall of the support frame 1. Multiple suction pipes 52 are fixedly installed on the hollow ring 51, all passing through the hollow shaft 2 and connected to the double cone drying cylinder 3. With the cooperation of the vacuum pump 5, a vacuum operation is performed on the double cone drying cylinder 3. A heating plate 46 is fixedly installed on the shell 4.

[0028] In this embodiment, in order to provide stable support for the multiple exhaust pipes 52 and to prevent air from entering the double cone drying cylinder 3 inside the hollow shaft 2, multiple circular plates 53 are rotatably and sealed on the inner wall of the hollow shaft 2, and the multiple exhaust pipes 52 are fixedly connected to the circular plates 53.

[0029] In this embodiment, in order to ensure the support stability of the shell 4 for the multiple stirring shafts 43, and at the same time ensure the working stability of the shell 4, a fixing rod 401 is fixedly installed on the shell 4, and the fixing rod 401 is fixedly connected to the inner wall of the double cone drying cylinder 3 and is located on the same axis as the hollow shaft 2.

[0030] In this embodiment, in order to prevent the sodium bromate raw material in the double cone drying cylinder 3 from being sucked into the vacuum pump 5, a spherical filter plate 54 is fixedly installed on the inner side wall of the double cone drying cylinder 3, and the spherical filter plate 54 is set around the rotating shaft 41 and rotatably connected to the rotating shaft 41.

[0031] In this embodiment, in order to monitor the material temperature in the double cone drying cylinder 3 in real time, and to facilitate the wiring of the temperature sensor 47 and the heating plate 46, the temperature sensor 47 is fixedly installed at the end of the stirring shaft 43 away from the housing 4, and both the stirring shaft 43 and the rotating shaft 41 are hollow.

[0032] The motors, temperature sensors, heating plates, circuits, wiring, electronic components, and modules involved all employ existing technologies, which can be fully implemented by those skilled in the art and need not be elaborated upon. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0033] Working principle: When in use, first turn on the power, put the sodium bromate raw material into the double cone drying cylinder 3 and start the motor 22. Through the meshing transmission of the driving gear 23 and the driven gear 21, the hollow shaft 2 and the double cone drying cylinder 3 rotate together. Since the rotating shaft 41 is fixed, the shell 4 moves synchronously with the double cone drying cylinder 3. At the same time, the first bevel gear 42 and multiple second bevel gears 45 are meshed, so that multiple stirring shafts 43 rotate on their own axis while revolving around the rotating shaft 41. Thus, the sodium bromate raw material can be evenly stirred with the cooperation of multiple stirring rods 44.

[0034] During the mixing process, the vacuum pump 5 is started, and the double cone drying cylinder 3 is evacuated through the hollow ring 51 and the suction pipe 52 to reduce the pressure inside the cylinder and accelerate the evaporation of moisture. Meanwhile, the electric heating plate 46 heats the material inside the double cone drying cylinder 3 to provide the heat required for drying. At the same time, the temperature sensor 47 monitors the temperature of the material inside the cylinder in real time to ensure that the drying process is carried out within a suitable temperature range, thereby achieving a low-temperature drying effect.

[0035] Because a spherical filter plate 54 is fixedly installed on the inner wall of the double cone drying cylinder 3, the sodium bromate raw material will not be sucked into the vacuum pump 5 even under vacuum conditions. At the same time, the arrangement of multiple circular plates 53 inside the hollow shaft 2 ensures the stable support of the suction pipe 52 and prevents outside air from entering the double cone drying cylinder 3 through the hollow shaft 2. This ensures that the double cone drying cylinder 3 can achieve stable vacuum operation in the cooperation of the vacuum pump 5, the hollow ring 51 and the suction pipe 52 during the drying process.
