[0002] It is known that, with the acceleration of urbanization and the increasingly stringent environmental protection requirements, the amount of sludge generated in the sewage treatment process increases sharply, the sludge contains a large amount of water, organic matter, pathogens and heavy metals and other pollutants, and if not properly treated, secondary pollution (such as soil degradation, groundwater pollution and greenhouse gas emission) is easy to occur, and the traditional sludge disposal methods (such as landfill, composting or direct incineration) have high transportation cost, low energy efficiency and great pollution risk due to high water content, so the sludge drying technology becomes a key link for realizing sludge reduction, stabilization and resource utilization.

[0003] In the related art, according to the search, the utility model with the patent publication number CN218174796U discloses a sludge drying equipment, which comprises a cylinder, a vacuum pipe arranged on one side of the cylinder, an inlet arranged on the top of the cylinder, an outlet arranged on the bottom of the cylinder, a main shaft penetrating through the cylinder is arranged on the central axis of the cylinder through a bearing seat, an inner cylinder located in the interior of the cylinder is arranged on the main shaft, the inner cylinder is connected with the vacuum pipe extending out of the cylinder, a water pipe connected with the cylinder is wound on the outer surface of the inner cylinder, a stirring assembly located in the interior of the inner cylinder is arranged on the side surface of the main shaft, the stirring assembly comprises a fixed plate fixedly connected with the side surface of the main shaft and a roller rotatably connected with the side surface of the fixed plate, the number of the fixed plates is two and they are symmetrically arranged at the two ends in the interior of the inner cylinder, the two ends of the roller are rotatably connected with the side surfaces of the two fixed plates, and a filter assembly is arranged in the interior of the vacuum pipe.

[0004] For the related art in the above, the applicant finds that although the existing device can realize uniform heating and drying of the sludge, it still has the following defects: in the sludge drying process, due to the high viscosity of the sludge itself and the water gradient effect, the material is easy to coagulate into lumps, this lumping phenomenon will cause the outer surface of the lump to dry quickly to form a hard shell, hinder the further evaporation of the internal water, and the internal drying of the lump is not sufficient due to the blocked heat transfer, finally affecting the overall drying effect.

[0005] Therefore, we propose a sludge drying equipment which can break the coagulated sludge into lumps in multiple dimensions. Utility model content
