Description

Technical Field

[0001] This utility model relates to the field of liquid dispersion technology, specifically to a flow dispersion device for hydrolysate synthesized from fermented cytosine. Background Technology

[0002] In the hydrolysis process for producing cytidine via fermentation, uniform dispersion of the liquid stream is a crucial factor affecting reaction efficiency and product quality. Cytidine, as an important nucleoside, is widely used in the pharmaceutical and biochemical fields. Its production process typically involves complex liquid-phase reaction systems. Problems such as high material viscosity and uneven solid-liquid mixing can easily lead to excessively high local concentrations and low mass transfer efficiency, thereby affecting the hydrolysis reaction rate and product yield.

[0003] In the prior art, a Chinese patent document with authorization announcement number CN219308463U describes a fermentation cytidine synthesis hydrolysate dispersion device. This patent uses a drive motor to drive a rotating rod to rotate, which in turn drives a first stirring rod on the rotating rod to rotate. The rotating rod, through a connecting rod, drives a scraper to rotate, which in turn drives a second stirring rod on the scraper to rotate. The first stirring rod, the second stirring rod, the first stirring blade, and the second stirring blade are used to stir and disperse the cytidine raw material. During the process, the power of a telescopic motor is turned on, which pushes a connecting plate to move. This causes the connecting plate to move the rotating rod and the drive motor up and down, thereby causing the rotating rod to move the first stirring rod and the second stirring rod up and down.

[0004] The core innovation of this patent lies in using a telescopic motor to drive the entire stirring mechanism (including the first stirring rod, the second stirring rod, and the scraper) to move up and down, thereby solving the problem of uneven mixing that may occur with traditional fixed stirring. However, it has the following drawbacks: 1. The rotating rod needs to rotate at high speed (driven by the drive motor) and also make up-down reciprocating motion (driven by the telescopic motor), which makes it very easy to wear out, increasing the cost of equipment maintenance and the risk of operation.

[0005] 2. The drive motor and stirring system are mounted on a vertically movable connecting plate, forming a cantilever structure. When the stirring mechanism is in a high position, the system's center of gravity shifts upward, making it prone to swaying and tilting. This causes the rotating rod to deviate from the center of the tank, resulting in vibration and noise, which seriously affects the equipment's lifespan and stirring efficiency.

[0006] To this end, we propose a flow dispersion device for the hydrolysate of fermented cytidine synthesis. Utility Model Content
