Description

An ethanol-free NMN crystallization reactor Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to an NMN ethanol-free crystallization reaction vessel. Background Technology

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposition vessels, and polymerization kettles. Materials typically include carbon manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel, Inconel), and other composite materials. The NMN non-ethanol crystallization reaction requires the use of a reaction vessel.

[0003] Utility model patent CN111803992A2 discloses a crystallization reactor, including a tank body, a reactor mechanism, a rotating mechanism, a driving mechanism, a connecting mechanism, a lifting mechanism, and an arc-shaped guide groove. The reactor mechanism is fixedly installed on the tank body and includes a support base, a feed inlet, a cover plate, a discharge outlet, a control valve, a rotating rod, a scraper, a mounting plate, and a brush. The support base is vertically fixedly installed at the lower end of the tank body. The feed inlet and discharge outlet are respectively located at the upper and lower ends of the tank body and communicate with its interior. The cover plate is located at the opening of the feed inlet, and an air valve is installed on the discharge outlet. The rotating rod is laterally rotatably connected to the interior of the tank body. The scraper and mounting plate are respectively fixedly installed at both ends of the rotating rod and located below the rotating rod, with the scraper abutting against the interior of the tank body. The crystallization reactor provided by this invention has the advantages of facilitating material handling, reducing the labor intensity of workers, and improving work efficiency.

[0004] Currently, during petroleum processing, crystals produced in the reactor tend to adhere to the inner wall of the reactor. These crystals are usually cleaned manually by workers, which is cumbersome and time-consuming. In addition, to facilitate material discharge, a long pipe is installed at the discharge port at the bottom of the reactor for material discharge. However, cleaning the inside of the discharge pipe through the long pipe is also quite troublesome. Summary of the Invention

[0005] The purpose of this invention is to provide an NMN ethanol-free crystallization reactor, which solves the technical problems of removing crystals from the inner wall of the reactor and preventing blockage of the discharge.
