Fig. 1 shows a schematic structural diagram of a reaction kettle 100 according to an embodiment of the present invention, and fig. 2 shows a schematic structural diagram of a stirring shaft of the reaction kettle 100 in fig. 1.

Specifically, the reaction kettle 100 comprises a reaction kettle body 10, a reaction kettle cover 20 and a stirring shaft 30. The reactor body 10 is of a barrel-like configuration defining a chamber 11 for receiving material. The reaction vessel cover 20 is fixed to the reaction vessel body 10, for example, by screws to the upper end of the reaction vessel body 10. The upper end of the stirring shaft 30 extends out of the reaction kettle cover 10, and the lower end extends into the bottom of the chamber 11 of the reaction kettle body 10. Wherein the centre of the mixer shaft 30 is formed with a central feed channel 31 for feeding material into the chamber 11.

In some embodiments, the central feed channel 31 is provided with an upper control valve 32 and a lower control valve 33, the upper control valve 32 and the lower control valve 33 forming a material receiving space 34 therebetween. An upper control valve 32 and a lower control valve 33 are used to effect opening and closing of the central feed channel 31.

In some embodiments, the material containing space 34 has a spherical space to increase the amount of material per feed.

In some embodiments, the reaction vessel 100 further comprises an inert gas channel in communication with the central feed channel 31, through which inert gas is delivered into the chamber 11 of the reaction vessel body 10 via the central feed channel 31 for isolating material from air during production. During feeding, the central feeding channel 31 can be communicated with the outside air, and the air cannot be mixed into the cavity 11 of the reaction kettle body 10, so that after feeding is completed, inert gas needs to be continuously introduced for discharging the air mixed during feeding.

In some embodiments, the reaction vessel cover 20 is provided with an exhaust valve, and when the inert gas is filled into the chamber 11 of the reaction vessel body 10, the air in the chamber 11 is exhausted through the exhaust valve.

In some embodiments, the mixer shaft 30 is further provided with an inclined discharge channel 35 communicating with the central feed channel 31.

In some embodiments, a low pressure zone is formed at the discharge opening 351 of the inclined discharge channel 35.

In some embodiments, the inclined outlet channels 35 are inclined at an angle of 30 ° to 60 ° relative to the central inlet channel 31. In some embodiments, the inclined outlet channel 35 is inclined at an angle of 45 ° relative to the central inlet channel 31. Through setting up slope discharging channel 35, be favorable to improving the input speed of material.

In some embodiments, the lower end of the stirring shaft 30 is provided with stirring blades 36. The upper end of the stirring shaft 30 is connected with a motor for driving the stirring shaft 30 to rotate. When the motor drives the stirring shaft 30 to rotate, the stirring shaft 30 drives the stirring blades 36 to rotate, so as to stir the materials in the chamber 11 of the reaction kettle body 10.

In some embodiments, reactor 100 further comprises a pressurizing device for pressurizing the material at feed inlet 311 of central feed channel 31. In some embodiments, reaction vessel 100 further comprises an air evacuation device for evacuating air from chamber 11 of reaction vessel body 10.

For the material with poor fluidity, the material is pressurized or the air in the reaction kettle body is pumped to form vacuum, so that the material in the central feeding channel 31 is favorably pumped and smoothly enters the cavity 11 of the reaction kettle body 10.

During the operation of the reaction kettle 100, when feeding is needed, the upper control valve 32 is opened, the lower control valve 33 is closed, and the material containing space 34 between the upper control valve 32 and the lower control valve 33 is filled with materials; then, the upper control valve 32 is closed, and the lower control valve 33 is opened, so that the material in the material accommodating space 34 is discharged to the bottom of the chamber 11 of the reaction vessel body 10 through the discharge port 351 of the inclined discharge channel 35.

Opening upper control valve 32, closing lower control valve 33, can guarantee that reation kettle 100 keeps apart with the external world, add the material in the material accommodation space 34 between upper control valve 32 and lower control valve 33 this moment, close upper control valve 32 after filling up, open lower control valve 33, the material gets into reation kettle 100 in, avoids reation kettle 100 inside and outside air contact to furthest. The amount of material fed each time is only as large as the space between the upper control valve 32 and the lower control valve 33, which can be operated many times, and the material accommodating space 34 can be enlarged to form a space in the shape of a sphere.

During the operation of the reaction vessel 100, the stirring shaft 30 rotates at a high speed. Due to the centrifugal force of high-speed rotation, a low-pressure area is formed at the discharge port 351 to generate a negative pressure adsorption effect, so that the materials in the inclined discharge channel 35 can be adsorbed into the chamber 11 of the reaction kettle body 10; and discharge gate 351 is in reation kettle 100's stirring mixture at reation kettle 100's bottom, and the feeding directly participates in the material stirring and mixes like this, avoids taking place layering isolation phenomenon from the reinforced material of top layer, especially drops in pulverous material on the top layer, can directly float and do not participate in the mixing stirring on the top layer.

According to the utility model discloses an embodiment, through the center of (mixing) shaft forms central feedstock channel can directly put in the material reation kettle's bottom avoids the material adhesion to be in the surface of (mixing) shaft. And, through form in the center of (mixing) shaft the central feedstock channel, can with the inside and the exterior space effective isolation of reation kettle, be favorable to carrying on the operation that has the isolated air requirement. The utility model discloses can be through accurate control center feedstock channel's feed rate to reach the material rate of throwing in the accurate control reation kettle.
