AI Technical Summary

Technical Problem

Existing stirred tanks used for producing polymerization inhibitors suffer from problems such as uneven mixing, raw material waste, equipment corrosion, and poor cleaning, which affect production efficiency and equipment lifespan.

Method used

It adopts a three-stage scraper collaborative design, including curved, straight and staggered serrated scrapers, and with an adaptive support structure, it can achieve precise cleaning of different areas of the vessel. The support component ensures the vertical position of the scraper through elastic elements and guide rods to avoid wear.

Benefits of technology

This process achieves uniform mixing of the polymerization inhibitor raw materials, reduces raw material waste and equipment maintenance costs, improves production efficiency and equipment utilization, and extends equipment life.

Abstract

This utility model relates to a self-cleaning stirred tank for producing polymerization inhibitors, comprising a tank body, a stirring rod disposed within the tank body, stirring paddles disposed on the stirring rod, a first scraper for cleaning the upper layer of the tank body, a second scraper for cleaning the middle layer of the tank body, a third scraper for cleaning the conical bottom of the tank body, and support members for supporting the scrapers; the stirring rod is rotated by a motor; several stirring paddles are arranged in a circumferential array; each set of first, second, and third scrapers corresponds to a support member; the support members are respectively disposed between two sets of stirring paddles; the first, second, and third scrapers rotate synchronously with the stirring rod. This invention solves the problems of stirred tanks with cleaning functions having limited cleaning effects or design flaws; moreover, traditional stirred tanks often require shutdown for separate cleaning, which is time-consuming and labor-intensive, reducing production efficiency.
