AI Technical Summary

Technical Problem

Existing stirring devices cannot fully and evenly stir liquids in fermenters with large diameters, and some raw materials are highly viscous and easily adhere to the inner wall of the fermenter, affecting the quality of acetic acid fermentation and increasing the operating burden of the device.

Method used

A stirring device including an adjusting plate, a limiting track, and a mounting plate was designed. By adjusting the diameter and position of the stirring plate, uniform stirring can be achieved in various positions within the fermenter. The device also uses a cleaning plate and a gear system to scrape off adhering raw materials, reducing the impact of adhesion.

Benefits of technology

This method achieves uniform mixing and cleaning of raw materials in the acetic acid fermentation tank, improves fermentation quality, and reduces the operating burden of the equipment.

Abstract

This utility model discloses a stirring device for acetic acid fermentation, including a fermentation tank. The fermentation tank has a top cover, and an upper fixed frame is rotatably installed inside the top cover. A lower fixed frame is fixedly installed on the upper fixed frame, and a limiting track is fixedly installed inside the lower fixed frame. Multiple sets of annularly distributed mounting plates are provided inside the lower fixed frame. Each of the mounting plates has a sliding rod fixedly installed, and each sliding rod has an adjusting rod fixedly installed. An adjusting disc is rotatably installed inside the upper fixed frame, and the adjusting disc has multiple sets of annularly distributed adjusting grooves. Stirring plates are rotatably installed on the mounting plates. The distance between the multiple annularly distributed mounting plates is adjusted by the adjusting disc, adjusting rods, and limiting track, thereby adjusting the diameter of the array formed by the multiple sets of stirring plates. This ensures that the acetic acid raw material in all positions within the fermentation tank is uniformly stirred.
