Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a high-efficiency sludge concentrating and dehydrating device. Background Art

[0002] High-efficiency sludge thickening and dehydration devices are special equipment used to reduce the volume of sludge and lower its water content. These devices play a vital role in the sewage treatment and recycling process, and can significantly reduce the subsequent treatment and transportation costs of sludge. When in use, the high-efficiency sludge thickening and dehydration device squeezes and transports the sludge through a spiral structure, and then filters it through a filter. However, the filter is easily blocked by solid debris when draining water, and sludge may also stick to the filter. In order to better dehydrate, the filter needs to be cleaned regularly. Since the filter is inside the device and is blocked by the lower liquid structure, it is not easy for the user to clean the filter. There are certain shortcomings. For this reason, we propose a high-efficiency sludge thickening and dehydration device. Utility Model Content
