Description

Technical Field

[0001] This utility model relates to the chemical industry, specifically to a reaction vessel that improves mixing efficiency. Background Technology

[0002] A reaction vessel is a specialized piece of equipment used for chemical reactions. It is typically made of steel plates of a certain thickness, possessing high corrosion resistance and the ability to withstand high temperatures and pressures. It is widely used in pharmaceuticals, chemicals, food processing, and other fields to meet the needs of different processes. Depending on the specific process requirements, it can be categorized into atmospheric pressure reaction vessels, high-pressure reaction vessels, and vacuum reaction vessels. It can accommodate chemical reactions under high pressure and high temperature conditions, and allows for heating or cooling operations during the reaction process to regulate the reaction rate and product yield. It is widely used in pharmaceuticals, polymer industries, organic synthesis, and other fields, making it an indispensable tool in the chemical industry.

[0003] Existing technologies still have certain drawbacks in the use of reaction vessels. Traditional reaction vessels usually add raw materials directly into the vessel. When a large amount of raw materials are mixed with the solution, lumps will form inside. The lumps will affect the overall mixing efficiency because the presence of lumps will hinder the full contact and uniform distribution of the raw materials, making the mixing more difficult, requiring a longer mixing time, and resulting in poor mixing effect.

Scrapers are located on both sides of the edge of the flow guide. A balance disc is located on the stirring shaft below the flow guide. An agitator is located below the balance disc. A discharge port is located in the middle of the bottom surface of the reactor body.

[0006] In a further embodiment, the fragmentation teeth are fixedly connected to the stirring shaft by threads, and the tips of the fragmentation teeth are spherical.

[0007] In a further embodiment, the flow guide shroud and the material mixing cylinder are connected by welding, and the stirring shaft is rotatably connected to both the material mixing cylinder and the flow guide shroud.
