Description

Technical Field

[0001] This utility model relates to the field of sludge scraper technology, specifically to a cantilever truss sludge scraper. Background Technology

[0002] Wastewater treatment tanks typically accumulate large amounts of sludge at the bottom. Sludge scrapers are usually used to clean the sludge from the bottom of the tank. When the scraper is running, the scraper blades rotate continuously at a certain speed, constantly scraping the settled sludge from the bottom of the tank into the sludge collection tank, forming a closed-loop working process. The truss scraper is a device that uses a truss to move along the length of the tank and uses scrapers suspended under the truss to scrape the sludge. It is widely used in the field of wastewater treatment.

[0003] The instruction manual for a truss scraper that is easy to maintain, as described in the prior art (publication number CN211706004U), mentions that "rollers that mesh with slide rails are fixedly installed on both the left and right sides of the bottom of the frame. The two rollers are fixedly connected by a shaft. A transmission gear is fixedly installed on the surface of the shaft. A control main box is fixedly installed on the top of the frame. A power motor is fixedly installed inside the control main box. A power gear is fixedly installed at the bottom of the output shaft of the power motor. A protective fence is fixedly installed on the top of the frame." Two sludge scraper frames are movably installed at the bottom of the frame, and a truss is fixedly installed between the two scraper frames. Sludge scraper plates are fixedly installed at the bottom of the scraper frames, and the scraper plates include pulleys and plastic plates. Cable piles are fixedly installed on the surface of the scraper frames. A cable motor is fixedly installed on the top of the control box, and a steel cable is wound on the surface of the output shaft of the cable motor. However, the existing truss scraper cannot flexibly adjust the scraping position, and it is inconvenient to remove the scraping structure for cleaning and maintenance. Moreover, it cannot simultaneously scrape the sludge on the inner wall of the sewage, and the scraping is not clean and convenient. Utility Model Content
