Description

Technical Field

[0001] The utility model relates to the technical field of raw mill sludge treatment and energy recovery, in particular to a raw mill sludge treatment device. Background Art

[0002] With the development of industrialization and the acceleration of urbanization, sludge as a waste has attracted widespread attention in environmental protection treatment. The process of sludge generation involves multiple fields, including industrial production, waste treatment, and urban domestic waste management. Not only does the amount of sludge continue to increase, but the diversity of its composition also increases the complexity of treatment.

[0003] Among them, waste treatment sludge includes sludge from municipal waste incineration and hazardous waste treatment, which may contain harmful chemicals and require special treatment methods to prevent its pollution to the environment. Heavy metal sludge may contain heavy metal elements such as cadmium, lead, and mercury, and its toxicity and persistence pose a serious threat to soil and water bodies. Construction waste sludge comes from waste from construction projects, which may contain gypsum, concrete and other components. It needs to be treated according to its characteristics to reduce waste of resources and impact on the environment.

[0004] In the cement production process, the recycled sludge can be processed and reused. Before the sludge is introduced into the raw mill, it needs to be properly pretreated to ensure the quality and performance of the sludge. The pretreatment design includes steps such as sludge drying, crushing and screening to reduce the adverse effects on the raw mill system. At the same time, sludge precipitation is prone to occur during the sludge storage stage, and the sludge contains organic compounds and possible toxic substances. If improperly handled, it will pose a potential threat to the environment and human health. Therefore, a raw mill sludge treatment device is needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a raw mill sludge treatment device, which has the advantages of avoiding sedimentation and agglomeration during sludge storage and avoiding sludge leakage and pollution, and solves the problems that sludge is prone to sedimentation during the sludge storage stage, and that the sludge contains organic compounds and possible toxic substances, which pose a potential threat to the environment and human health if not handled properly.

In order to prevent sludge leakage, a first cover is installed on the top of the storage bin, and a first auger is arranged in the storage bin, so that the first auger can be rotated clockwise in the storage bin to achieve stirring of the sludge in the storage bin, thereby preventing the sludge from settling.

When the second auger rotates, the sludge can be transported through the feed pipe, and the sludge will not leak during the transportation stage. At the same time, the sludge is squeezed into the discharge trough through the feed pipe, and the sludge enters the next processing step through the discharge trough.
