Description

Technical Field

[0001] The utility model relates to the field of acrylic acid production, in particular to an acrylic acid reaction kettle. Background Art

[0002] After searching Chinese patents, the publication number is: CN218339735U. The polyurethane acrylic reactor that is convenient for loading and unloading includes a main body mechanism, a loading and stirring mechanism and a collecting mechanism. The loading and stirring mechanism is located at the upper end of the main body mechanism, and the collecting mechanism is located below the main body mechanism. The main body mechanism includes a reactor body, a workbench and supporting feet. The workbench is fixedly installed at the lower end of the reactor body, and the supporting feet are fixedly installed at the lower end of the workbench. The supporting feet are evenly distributed at the lower end of the workbench. The polyurethane acrylic reactor that is convenient for loading and unloading is installed with a loading and stirring mechanism. Opening the first valve facilitates the flow of materials in the storage box to the inside of the reactor body. The stirring motor drives the stirring blades to rotate to fully stir the materials. When the materials in the reactor body are fully stirred, opening the second valve facilitates the materials to flow out through the discharge port, thereby improving work efficiency.

[0003] The existing reactor has low stirring efficiency. In order to improve the reaction efficiency, a general reactor needs to be stirred by a stirring mechanism. The stirring mechanism usually drives the stirring rod to rotate in one direction by a motor to stir it, and the stirring direction is single, which reduces the stirring efficiency and makes it difficult to fully and evenly mix the materials, thereby reducing the reaction efficiency and being inconvenient for maintenance. Generally, after a long period of use, the reactor needs to be maintained inside to ensure the normal operation of the reactor. The reactor cover and the reactor body are fixed by multiple bolts. When maintaining the inside, tools are needed to disassemble and assemble it. The entire maintenance process is time-consuming and cumbersome, which increases the workload and reduces the work efficiency. In order to solve the above problems, we propose an acrylic reactor.
