Description

Technical Field

[0001] The utility model relates to the technical field of wet cutting, in particular to a wet cutting device for anaerobic fermentation. Background Technique

[0002] The biogas project has been developed in China for many years, and the efficient anaerobic fermentation technology has been continuously iterated and updated. At present, most of the straw anaerobic fermentations are basically through two-stage anaerobic fermentation, mostly through multiple processes such as crushing, hydrolysis, stirring, and solid-liquid separation. However, in the actual project operation, when the materials enter the second-stage anaerobic tank, problems such as pipeline blockage, equipment blockage, and low degradation efficiency will still occur. Therefore, a wet cutting device is needed to crush and cut the materials therein.

[0003] At present, most wet cutting devices are installed in the pumping system between the first-stage reactor and the second-stage reactor. The materials pass from the first-stage reactor to the cutting cylinder through the pumping system, and after being finely ground by the rapidly rotating blade hammers with flow rings, they reach the cutting equipment of the second-stage reactor. Under high-speed cutting, the materials to be fermented are quickly decomposed, improving the pipeline passability. The design of multiple diversion ports makes the entire operation system more flexible and convenient. However, it is found in actual operation that due to the good sealing of the entire breaking cylinder, after the cutting reamer in it has been cutting for a long time, its cutting edge is prone to wear, thus affecting the cutting effect. And it is inconvenient to replace the reamer of the existing wet cutting device's breaking cylinder, and each time the entire reamer disc is replaced, it is impossible to replace only the damaged single reamer blade. Therefore, it is necessary to design a wet cutting device for anaerobic fermentation that is convenient for quickly replacing the reamer and can replace a single reamer blade to solve the above problems.
