Description

Full-bridge type peripheral transmission mud scraper Technical Field The utility model relates to the technical field of sewage treatment equipment, in particular to a full-bridge type peripheral transmission mud scraper. Background In industries such as sewage treatment and municipal fields, the sedimentation tank is the key facility that is used for realizing solid-liquid separation, and the sedimentation tank bottom can accumulate mud gradually, if not in time clear up, can influence sedimentation tank's treatment effect and operating efficiency, probably lead to the equipment trouble even. Therefore, the application of the mud scraper is of great importance. The conventional mud scraper has a plurality of defects. The partial mud scraper has simple structure, but the working bridge is mostly of a half-bridge type or other non-full-bridge type structure, the coverage range is limited, the sedimentation tank is difficult to carry out comprehensive and efficient mud scraping operation, and the sludge in partial areas of the bottom of the sedimentation tank is not thoroughly cleaned. The driving and transmission modes of the mud scraper are unreasonable, and the installation position of the driving device or the transmission mechanism form enables unstable power transmission and easy transmission failure to occur, so that the normal operation of the mud scraper is affected. In the aspect of the mud scraping device, the traditional mud scraping plate is poor in material and structural design, poor in laminating degree with the bottom of the pool, unsatisfactory in mud scraping effect, and easy to deviate or damage due to factors such as resistance in the operation process.
