Description

Technical Field

[0001] The utility model relates to the technical field of sludge dewatering, in particular to a pair-roll dewatering device for urban sludge. Background Technique

[0002] The components included in urban sewage are relatively complex, and it includes solid sludge and sewage at the same time. When discharging sewage, the sludge will be gradually pushed forward. At relatively narrow pipe sections or pipe bends, the phenomenon of pipe blockage will occur, affecting the drainage smoothness. When it rains, due to the existence of sludge, rainwater cannot be discharged in time, resulting in sewage overflow, which not only affects urban traffic but also causes ground pollution. Therefore, workers often need to clean the sludge in the pipeline.

[0003] Existing devices usually use pair-rolls to squeeze out the sewage in the sludge and then process the dried sludge. However, when dehydrating sludge, a large amount of mud often adheres to the pair-rolls of existing devices. Existing devices usually require workers to stop the device and then manually scrape and clean the mud on the pair-rolls, resulting in poor scraping effect of the mud on the pair-rolls. Workers spend a lot of time and effort in cleaning, affecting the working efficiency of the device. Therefore, it is necessary to design and transform the pair-roll dewatering device for urban sludge to solve the problem of inconvenient cleaning caused by sludge contamination on the surface of the pair-rolls.
