Description

Technical Field

[0001] The utility model belongs to the technical field of raw rubber reaction, in particular to a raw rubber reaction kettle. Background Art

[0002] Silicone rubber is made of dimethylsiloxane mixed ring or octamethylcyclotetrasiloxane, small materials, and catalyst. The polymerization reaction is carried out under certain temperature and vacuum conditions. After the polymerization reaction is completed, the catalyst, unreacted small molecules and other substances in the polymer are removed by a low molecular weight removal device, and then the material is discharged through a cooler.

[0003] After searching, a document with publication number (CN218689402U) discloses a raw rubber polymerization reactor, including a reactor, a transmission box fixedly provided on the reactor, an upper cover fixedly provided on the transmission box, a rotating connecting disk fixedly provided in the transmission box, a rotating box fixedly provided below the connecting disk, a rotating main shaft provided in the center of the rotating box, a secondary shaft rotating in a circle along the axis of the main shaft provided on one side of the main shaft, the secondary shaft rotates against the rotating box, a main paddle blade fixedly provided at the end of the main shaft, a secondary paddle blade fixedly provided at the end of the secondary shaft, the main paddle blade and the secondary paddle blade are arranged in the reactor for kneading and rotation.

[0004] The above device mixes, heats and stirs the raw materials through a heater and a rotating kneading main blade and an auxiliary blade to ensure sufficient mixing of the raw materials, and then evenly sprays the catalyst through a nozzle. The kneading, stirring and heating cause the catalyst to fully react with the raw materials for polymerization. The auxiliary blade rotates synchronously with the main blade, and the auxiliary blade revolves around the main blade, thereby ensuring sufficient mixing.

[0005] However, in the existing device, the raw materials need to be mixed and stirred before being poured into the reactor for stirring reaction. The raw materials need to be transported before reacting. The raw rubber will solidify due to water loss during transportation, resulting in a waste of raw materials.

[0006] At the same time, after the raw rubber reaction, a large amount of raw rubber residue will remain on the inner wall of the reactor. The residue will remain in the reactor and solidify, thereby occupying the space inside the reactor. At the same time, the raw rubber residue remaining inside will undergo a qualitative change, thus affecting the subsequent raw rubber reaction quality.

[0007] In view of this, the present utility model is proposed. Utility Model Content
