Description

TECHNICAL FIELD

[0002] Sludge drying is an important link in the process of sludge treatment, and its purpose is to remove most of the water in the sludge, so that the sludge achieves the treatment effect of reduction, stabilization and harmlessness. Sludge drying reduces the moisture content of sludge through physical, chemical or biological methods, such as natural evaporation or mechanical dewatering, which facilitates the transportation, stacking, utilization or further treatment of sludge. Sludge drying is divided into two stages: dewatering stage and drying stage. In the dewatering stage, free water in the sludge is removed by extrusion, filtration and other methods; in the drying stage, bound water in the sludge is evaporated by hot air convection, contact heat transfer and other methods. The drying process not only helps to reduce the volume of sludge, facilitating storage and transportation, but also improves the calorific value of sludge, providing conditions for subsequent incineration or energy utilization. Sludge drying is an effective means to achieve sludge reduction, resource utilization and harmlessness, and is of great significance to environmental protection and resource recycling.

[0003] After sludge drying, the subsequent transmission link is also crucial to the efficiency and cost control of the entire treatment process. Given the characteristics of dried sludge, the transmission method needs to be efficient, stable and capable of small-scale, continuous operation. In this context, conveyor belt conveying becomes an ideal choice. Conveyor belt conveying system can smoothly and continuously convey dried sludge from one place to another, especially suitable for internal or short-distance sludge transmission in treatment plants. This transmission method not only has simple operation and low maintenance cost, but also effectively avoids the scattering and secondary pollution of sludge during transmission. For space-limited, short-distance transmission facilities, conveyor belt conveying significantly improves the overall efficiency of sludge treatment due to its flexible layout and efficient transmission characteristics. At the same time, by optimizing the material and running speed of the conveyor belt, the stability and safety of the sludge during transmission can be further ensured, laying a solid foundation for subsequent sludge treatment or resource utilization.

These imprints are mainly formed by the attachment of small particles of dried sludge to the surface of the conveyor belt during transportation. If not cleaned in time, it will not only affect the running efficiency and service life of the conveyor belt, but also may cause the sludge particles to scatter again into the working environment, increasing the risk of secondary pollution and causing unnecessary trouble and cost to the subsequent sludge treatment process.
