Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a sludge concentrator which is convenient for extracting supernatant liquid. Background Art

[0002] The sludge concentrator is a central transmission type continuous or intermittent concentrating and clarifying equipment in terms of structure. It is mainly composed of five parts: a concentrating tank, a specially designed high-torque water-type bridge, a main transmission mechanism, a lifting mechanism, and a slag rake. As the flow rate decreases, the suspended matter in the sludge water is separated and settled at the bottom of the tank. The scraper scrapes the precipitated sludge into the central sludge collecting tank and discharges it from the sludge pipe by hydrostatic pressure. The existing technology cannot completely discharge the sludge because it relies on hydrostatic pressure to discharge the sludge. In the long run, it will block the sludge pipeline, affect the normal operation of the equipment as a whole, and make it difficult to extract the supernatant. Utility Model Content
