[0024] This embodiment provides a stirrer, which includes a motor 1 and a stirring shaft 2 arranged below the motor 1. The stirring shaft 2 is in transmission connection with the motor 1. Its specific structure is as Figure 1 shown. A stirring device 3 is connected below the stirring shaft 2, a rotary seal mechanism 4 is arranged below the stirring device 3, a rotary seal shaft 5 is arranged at the lower end of the stirring device 3. The stirring shaft 2, the stirring device 3, and the rotary seal shaft 4 are all hollow and are sequentially communicated. The rotary seal shaft 5 and the rotary seal mechanism 4 are rotationally communicated; it also includes a steam inlet pipe 6, and the steam inlet pipe 6 is communicated to the rotary seal mechanism 4; several air outlet holes 7 are evenly arranged on the upper side surface of the stirring shaft 2.

[0025] During use, hot steam is introduced into the interior of the rotary seal mechanism 4 from the steam inlet pipe 6, and then sequentially enters the rotary seal shaft 5, the stirring device 3, and the stirring shaft 2 upward, and finally is discharged through the air outlet holes 7. During the rising process of the steam, especially in the stirring device 3, during the stirring process as the stirring device 3 rotates, heat exchange occurs with the outside of the stirring device 3, heating the external materials, achieving the purpose of stirring and heating simultaneously.

[0026] Embodiment 2

[0027] The stirring device 3 of this embodiment includes a stirring unit formed by spiraling two ventilation pipes 31. The two stirring units are symmetrically arranged, and the upper ends of both ventilation pipes 31 are fixedly communicated with the stirring shaft 2, and the lower ends are fixedly communicated with the rotary seal shaft 5.

[0028] The rest is the same as Embodiment 1.

[0029] The spiral stirring unit in this embodiment can not only rotate with the stirring shaft 2 during the rotation of the stirring shaft 2 as a stirring structure to stir the materials, but also increase the travel of the hot steam during the rising process of the hot steam, increase the heat exchange time, improve the heat exchange rate, so that the materials outside the stirring device 2 are fully heated during the stirring process, and the heating efficiency is high.

[0030] Embodiment 3

[0031] The rotary sealing mechanism 4 of this embodiment includes a sealing box 41. A sealing chamber 42 is provided inside the sealing box 41. The rotary sealing shaft 5 extends downward from the upper end of the sealing box 41 to communicate with the sealing chamber 42. A sealing device is provided in the upper part of the sealing chamber 42 of the sealing box 41. The rotary sealing shaft 5 is rotationally sealed with the sealing box 1 through the sealing device. The steam inlet pipe 6 horizontally extends from the side of the sealing box 41 to communicate with the sealing chamber 42.

[0032] The rest is the same as in Embodiment 2.

[0033] When the rotary sealing mechanism 4 of this embodiment is in use, first, the rotary sealing shaft 5 communicating with the inside of the sealing chamber 42 is rotationally sealed through the sealing device to ensure its sealing with the sealing box 41 during the rotation process. Hot steam is introduced through the steam inlet pipe 6. The hot steam enters the sealing chamber 42 and then enters the rotary sealing shaft 5 and the ventilation pipe 31 upward, and then is stirred and heated in the stirring device 3.

[0034] Embodiment 4

[0035] The sealing device of this embodiment is two sealing rings 431. As Figure 2 shown, at the part of the sealing box 41 above the sealing chamber 42, two sealing ring grooves 432 are provided corresponding to the rotary sealing shaft 5 in the vertical direction. The two sealing rings 431 are respectively fixed inside the two sealing ring grooves 432. After the rotary sealing shaft 5 is inserted into the sealing box 1, the sealing rings 431 and the rotary sealing shaft 5 are squeezed and sealed.

[0036] The rest is the same as in Embodiment 3.

[0037] The sealing ring 431 of this embodiment is sealed with the rotary sealing shaft 5 during the rotation process of the rotary sealing shaft 5, preventing materials from entering the sealing chamber 42 and affecting the operation of the device and hindering the introduction of hot steam.

[0038] Embodiment 5

[0039] The sealing device is a sealing packing 433. As Figure 3 shown, at the part of the sealing box 41 above the sealing chamber 42, a packing ring groove 434 is provided corresponding to the rotary sealing shaft 5. The sealing packing 433 is filled in the packing ring groove 434. When the filled sealing packing 433 is not under external force, its inner diameter is smaller than the outer diameter of the rotary sealing shaft 5. After the rotary sealing shaft 5 is inserted into the sealing box 1, the rotary sealing shaft 5 and the sealing packing 433 are squeezed and sealed.

[0040] The rest is the same as in Embodiment 3.

[0041] Preferably, the sealing packing 433 of this embodiment is polytetrafluoroethylene or tetrafluoro packing, which has corrosion resistance, good self-lubricity and anti-sticking properties.

The stirring shaft 2 penetrates downward through the production kettle body 8, and the stirring device 3, the rotary seal shaft 5 and the rotary seal mechanism 4 are all arranged inside the production kettle body 8. The seal box 41 is also arranged on the inner bottom of the production kettle body 8 through the support legs 10, and the seal box 41 is supported by the support legs 10 to prevent the seal box 41 from being directly placed on the inner bottom of the production kettle body 8 and affecting the discharge of materials.

[0044] One end of the steam inlet pipe 6 not connected to the rotary seal mechanism 4 penetrates through the production kettle body 8 and extends outward; a discharge pipe 11 is also connected to the bottom of the production kettle body 8, and a discharge valve 12 is arranged on the discharge pipe 11; a heat preservation layer 13 is also arranged on the side of the production kettle body 8 to further strengthen the maintenance of the temperature inside the production kettle body 8, so as to better reach the temperature required in the coating production and processing. The heat preservation layer 13 can keep warm through the heat preservation layer when the materials inside the production kettle body 8 reach the required temperature, and in this process, it is not necessary to introduce steam to heat in the stirring device 3. When the temperature drops, steam is introduced for heating again.
