Description

Technical Field

[0001] The invention relates to the technical field of rubber accelerator processing and preparation, in particular to a rubber accelerator oxidation kettle mixing and stirring method and device. Background Art

[0002] Rubber accelerator diphenylguanidine is an important accelerator used in rubber vulcanization. Diphenylguanidine accelerator is usually produced by oxygen catalytic oxidation. During the production process, diphenylthiourea and ammonia water are added to the oxidation kettle, and a catalyst is added and oxygen is introduced to produce diphenylguanidine. In this process, the raw materials of diphenylguanidine need to be stirred.

[0003] The Chinese utility model patent with announcement number CN215389035U proposes a stirring device for a rubber accelerator diphenylguanidine oxidation kettle, including an oxidation kettle body, a feed pipe arranged at the top side end of the oxidation kettle body, a first control valve arranged on the feed pipe, a discharge pipe arranged at the bottom of the oxidation kettle body, a second control valve arranged on the discharge pipe, an oxygenation chamber arranged inside the side wall of the oxidation kettle body, an injection hole arranged between the oxidation kettle body and the oxygenation chamber, an air inlet pipe arranged on the outer side wall of the oxidation kettle body and connected to the oxygenation chamber, and a third control valve arranged on the air inlet pipe.

[0004] The above technical solution allows oxygen to enter the interior of the oxidation kettle body quickly and at multiple angles through the coordination of the oxygenation chamber and multiple gas injection holes. However, since the gas injection holes are arranged on the inner wall of the oxidation kettle body, after the reaction is completed, the diphenylguanidine raw material can easily enter the interior of the oxygenation chamber through the gas injection holes and block the gas injection holes and the oxygenation chamber, making it inconvenient to clean, thereby affecting the subsequent oxygen introduction and the reaction between the diphenylguanidine raw materials.
