Background

When sewage plants treat sewage, a large amount of sludge is produced. The sludge particles of the sludge are in micron order, the water content is very high, generally 99.2-99.6%, and the sludge contains a large amount of organic components and is approximately in a colloid state. Transportation and storage of such high moisture content sludges is very difficult because the high moisture content sludges are typically large in volume and therefore expensive to transport and store. In addition, such sludge is difficult to be completely dried under natural storage conditions, and requires a large amount of land resources to store the sludge for a long period of time, and the sludge itself has pathogens such as heavy metals, harmful bacteria, etc. during the storage process, if it is treated in a conventional manner (e.g., natural storage or landfill), it often causes serious environmental pollution. In order to better treat the sludge, the water content of the sludge needs to be reduced through sludge concentration, the volume of the sludge is reduced, and the transportation and storage cost of the sludge can be reduced. However, the current sludge treatment standard is continuously strengthened, and the water content of the concentrated sludge is still very high, which is not beneficial to direct outward transportation and disposal. For better post-treatment of the sludge, the sludge may be conditioned by adding additives for subsequent processing of the concentrated and conditioned sludge.

Because mud need stir it in order to accelerate the mixture of mud and additive at the quenching and tempering in-process, however, the agitating unit axle often adopts the direct type to connect through the reduction gear at present, damages the counter shaft easily in the use, and the installation is inconvenient. Secondly, the stirring device used in the concentrated tempering system is installed by adopting an upper fixing mode all the time, however, the stirring device is only in the upper fixing mode, the middle lower part of the rotating shaft can shake in the stirring process to cause the phenomenon of deviating from the axis, and the blades of the stirring shaft are easy to damage the shell wall due to beating, thereby influencing the concentrated tempering.

Therefore, the self-adaptive flexible stirring device for the concentration tempering system, which can uniformly stir the sludge according to the characteristics of the sludge and can effectively solve the installation and subsequent maintenance difficulty, is expected.
