The invention relates to the field of sewer sludge processing, in particular to a scraper type sewer sludge removing device. The scraper type sewer sludge removing device is composed of a scraper conveyer, an overflowing weir plate, a water tank, gravel padding and an air conveying pipeline. A sludge feed inlet and a washing water spray inlet are formed in the upper portion of the scraper conveyer, and the sludge feed inlet is located in the front end of the washing water spray inlet. The water tank is located at the lower portion of the scraper conveyer. A sieve plate with meshes is arranged at the upper portion of the water tank. The air conveying pipeline is located at the lower portion of the water tank. The gravel padding is arranged in the water tank. The overflowing weir plate is located at the front end of the water tank. Sewer sludge is fed into the scraper conveyer and removed under the action of waterpower and air floatation, the amount of the sewer sludge is reduced, and the sewer sludge is stable and harmless.
Description
technical field [0001] The invention relates to the field of trench sludge treatment, in particular to a scraper type trench sludge cleaning device. Background technique [0002] Ditch sludge is the sludge that is removed during the regular maintenance of the pipeline system. It is mainly composed of sand, gravel, and a small amount of organic matter. Since a large amount of domestic garbage and pathogenic microorganisms have accumulated in it, if not properly disposed of, it will not only cause secondary pollution of the environment, but also pose a great threat to human health. [0003] At present, the main methods of trench sludge treatment at home and abroad include landfill, natural air drying, heating and drying, mechanical dehydration, and methods such as being used as raw materials for concrete and mortar production. However, there are many disadvantages in the above disposal methods: the water content of trench sludge is high, the efficiency of landfill and natural...
