Description

Technical Field

[0001] This utility model relates to the field of phenylethylamine production, specifically to a reaction vessel with self-cleaning function for phenylethylamine production. Background Technology

[0002] In modern chemical production, mixing is a crucial step in many processes, including the processing of chemical products. Stirred reaction vessels, consisting of a stirring structure and a vessel body, are the most common and convenient mixing equipment used in chemical plants. For example, in the production of phenethylamine, stirred reaction vessels are required to achieve the rotational stirring of the solution.

[0003] However, in the process of using existing stirred tanks, the stirring motor drives the stirring shaft and stirring rod to rotate and stir the solution. The stirring blades in the stirred tank can only provide horizontal stirring. Vertical stirring relies solely on the rotation of the material to drive the mixing. The stirring efficiency of the stirred tank is low. In addition, existing stirred tanks lack cleaning components to clean the tank wall. After the production of p-phenylethylamine is completed, phenylethylamine is easily left on the inner wall of the reactor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a self-cleaning reactor for phenylethylamine production, thus solving the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning reactor for phenethylamine production, comprising a reactor, a discharge pipe fixedly connected to the bottom of the reactor, a worm gear, a worm, a top cover, and cylinders; a top cover is movably installed on the top of the reactor; two cylinders are fixedly installed on both sides of the reactor, with the telescopic ends of the cylinders fixedly connected to the top cover; a first motor is fixedly installed on the top cover via a motor frame, a worm gear is fixedly installed on the drive end of the first motor; a worm gear meshing with the worm gear is movably installed on the top cover, the bottom of the worm gear extends into the reactor and a rotating rod is fixedly installed thereon, and several stirring rods are fixedly installed on the rotating rod.

[0006] Preferably, a pair of mounting plates are rotatably installed inside the reactor, and a plurality of springs are fixedly mounted on the pair of mounting plates, with scrapers fixedly connected to the other ends of the springs.

[0007] Preferably, a support leg is fixedly installed at the bottom of the reactor.

[0010] Preferably, a water inlet pipe is fixedly connected to the top cover, and the water inlet pipe is connected to the annular cavity.

[0011] Beneficial effects

[0012] This invention provides a self-cleaning reactor for phenylethylamine production, which has the following advantages:

[0013] 1. By installing a reaction vessel, the reactants can be stirred inside, thus making the reaction more complete. By installing a discharge pipe, the reactants can be discharged through the discharge pipe. By installing a cylinder, starting the cylinder and extending or retracting the cylinder can drive the top cover to rise or fall. Opening the top cover allows the reactants to be introduced from the top of the reaction vessel. After closing the top cover, the reaction vessel becomes a relatively closed chamber, preventing other impurities from entering and affecting the reaction. By installing a first motor, starting the first motor drives the worm gear to rotate. Through the meshing of the worm gear and the worm, the worm can be driven to rise and fall while rotating, which can drive the stirring rod to rise and fall while rotating, effectively improving the stirring efficiency of the reaction vessel.

[0014] 2. A second motor is installed. When the second motor is started, the drive end of the second motor rotates, which drives the gear to rotate. The gear meshes with the gear ring, which drives the gear ring to rotate, which in turn drives a pair of rotating plates to rotate, and then drives a pair of mounting plates to rotate. The mounting plates are installed, and the rotation of the mounting plates drives the scraper to rotate. The spring installed allows the scraper to adhere to the vessel wall, and the scraper can clean the vessel wall. Attached Figure Description

The worm wheel 4 meshes with the worm 5, causing the worm 5 to rise and fall while rotating, which can stir the raw materials in the reactor 1 and make them react fully. When it is necessary to clean the reactor 1, the second motor 12 is started, driving the gear 13 to rotate. The gear 13 meshes with the gear ring 14, causing the gear ring 14 to rotate, which in turn drives a pair of rotating plates 15 and a pair of mounting plates 16 to rotate, and at the same time drives the scraper 17 to rotate to clean the reactor wall.
