Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to an atmospheric pressure reaction kettle capable of continuously detecting the pH value. Background Technique

[0002] Generally speaking, a reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are achieved.

[0003] Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food. They are pressure vessels used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation, such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; the materials are generally carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys, and other composite materials.

[0004] When the traditional reaction kettle detects the internal pH index, the method is to directly install the pH value detection sensor inside the reaction kettle. This detection method can only detect the pH value of the solution at the same liquid level in the kettle. When different materials are mixed and stirred, it is necessary to adjust the height of the sensor in the kettle. The existing height adjustment method of the pH value sensor is very inconvenient and will cause the sealing performance of the reaction kettle to decline.

[0005] Therefore, how to provide an atmospheric pressure reaction kettle capable of continuously detecting the pH value to solve the problems existing in the prior art is of great significance for its application. Summary of the Utility Model
