Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction kettles, in particular to a high-efficiency chemical reaction kettle. Background Art

[0002] The reactor is a comprehensive reaction vessel, which can complete the pre-set reaction steps from the initial feeding-reaction-discharging with a high degree of automation. In the production process of rubber accelerators, the reaction of the raw materials in the reactor can be visually judged by observing the color. The existing reactors are all observed by setting an observation window on the surface of the reactor body. This method has the following disadvantages: First, there is usually a blind spot in the observation window, which makes it impossible for the observer to fully judge the reaction situation in the reactor, thereby terminating the reaction in advance or late, resulting in incomplete reaction, poor product quality and low production efficiency; second, when the raw materials in the reactor are stirred, the raw materials will flush and rub the observation window for a long time, causing the transparent glass plate to break, resulting in the scrapping of the raw materials.

[0003] Therefore, the Chinese utility model patent with an authorization announcement date of 2020.05.19 and an authorization announcement number of CN 210545129 U discloses a chemical reactor that is convenient for observation, including a main body and three groups of observation components evenly distributed on one side of the outer wall of the main body, the observation component consisting of a connecting pipe, a first control valve, an observation tube, and a push-pull rod.

[0004] When the above observation assembly is used, if the endpoint of the chemical raw material reaction is to be accurately determined, the second control valve and the first control valve of the three observation assemblies must be frequently opened to form a communicating vessel between the observation tube, the connecting tube and the main body, and the first control valve and the second control valve of the three observation assemblies must be closed respectively after the mixed raw material enters the observation tube. The operation process is frequent and complicated, which greatly increases the workload of personnel and reduces production efficiency. Moreover, after the observation, the mixed raw material has no channel to return to the kettle, resulting in a waste of raw materials. Utility Model Content
