A device for scraping the inner wall of a residual sodium sulfite reaction kettle

Abstract

This utility model relates to the field of reactor inner wall scraping technology, specifically a device for easily cleaning residual sodium sulfite from the inner wall of a reactor. The device includes a reactor body, with a drive motor fixedly connected to the center of the bottom surface of the reactor body. The advantages of this utility model are: the rotation of the rotating tube drives several cleaning scrapers to rotate against the inner wall of the reactor body, achieving scraping and cleaning of the inner wall. Simultaneously, a high-pressure water pump supplies high-pressure water to the rotating tube, which is then sprayed through a corrosion-resistant nozzle at the end of the rotating tube onto the contact point between the cleaning scrapers and the reactor body. This water flow softens and washes away residues adhering to the surface of the cleaning scrapers, improving the cleaning effect and extending the service life of the cleaning scrapers. The rotation of the bottom scraper cleans the bottom surface of the reactor inner wall and, during discharge, scrapes the material at the bottom towards the discharge valve, facilitating complete material discharge.

Description

Technical Field

[0001] This utility model relates to the field of scraping technology for the inner wall of a reaction vessel, and in particular to a scraping device for cleaning residual sodium sulfite from the inner wall of a reaction vessel. Background Technology

[0002] In the chemical production field, sodium sulfite is an important chemical raw material, often used in reaction vessels for various chemical reactions. After the reaction, sodium sulfite and its reaction products adhere to the inner wall of the reaction vessel, forming residues. If these residues are not cleaned in time, they will not only affect the quality of the next batch of products, but may also cause equipment corrosion and shorten the service life of the reaction vessel.

[0003] Current methods for cleaning residual sodium sulfite in reactors involve using a scraper attached to the end of a stirring rod to scrape off the residue adhering to the inner wall. However, while the residue is scraped off during cleaning, it causes a large amount of residue to adhere to the scraper, affecting the cleaning effect and accelerating the corrosion of the scraper, thus reducing its service life.
