By feeding different raw materials into a metering feed assembly, the raw materials are quantitatively added into the spiral tube by opening the metering feed assembly. The spiral mixing and conveying assembly is activated to realize the function of conveying and mixing the raw materials. Further mixing is achieved by the stirring and mixing assembly. The raw materials enter the discharge pipe through the mixing chamber and are further mixed by the filtration and mixing assembly. Thus, the tubular structure achieves the function of efficient mixing.

When the tubular packed reactor is subjected to vibration, the connecting parts between the tubular packed reactors may loosen, affecting their normal operation. Furthermore, during the extended service life of existing tubular packed reactors, corrosion and rust may occur on the outer surface due to external environmental factors. This corrosion and rust affects the strength of the tubular packed reactor, thus shortening its service life. Utility Model Content
