Description

Active dissolving device, concentration tempering system and self-balancing device thereof

Technical Field

The utility model relates to a technical field of sludge treatment, more specifically, the utility model relates to an active dissolving device, concentrated quenching and tempering system and self-balancing unit of mud and solid-state additive.

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, the sludge is difficult to be completely dried under the natural storage condition, a large amount of land resources are required to be occupied for storing the sludge for a long time, and the sludge has pathogens such as heavy metals, harmful bacteria and the like in the storage process. If disposed of in a conventional manner (e.g., natural storage or landfill), it often results in serious environmental pollution. In order to better treat the disposed 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 treatment of the sludge. 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 speed reducer at present, damages the counter shaft easily in the use, and the installation is inconvenient. Secondly, the stirring device used in the concentration tempering system is installed in 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 deviation from the axis, and the blades of the stirring shaft are easy to hit the wall of the storage tank to cause damage, thereby influencing concentration tempering.

In addition, solid and liquid additives are required to be added in sludge conditioning, and the solid additives such as the liquid sludge directly added to more than 99% are difficult to be fully mixed, so that the solid additives are not fully dissolved in the sludge to play a due role, and are discharged together with supernatant liquid to cause additive waste.

Therefore, an active dissolution device, a concentration conditioning system and a self-balancing device thereof are desired, which can solve the problems that the stirring device is not deviated from the axis during the use process and can be completely dissolved and fully reacted.
