Clarification tank stirring and mud-scraping machine

Abstract

The invention provides a stirring mud scraper for a clarification tank, which includes a steady flow cylinder, a reducer, a sleeve coupling, a working bridge, a lubricating water pipe, a rake frame, a transmission shaft, a mud scraper, a mud discharge pipe and a connecting flange , one end of the reducer is arranged inside the steady flow cylinder and the bottom end of the reducer is connected with a transmission shaft, the steady flow cylinder is arranged inside the working bridge, the surface of one end of the transmission shaft is fixed with a sleeve coupling and The transmission shaft runs through the bottom end of the steady flow cylinder, and the other end of the transmission shaft is provided with a connecting flange, and the connecting flange is connected with a plurality of steel wire ropes. The present invention has compact structure, high reliability, good stability, and no shaking , stable transmission, low power consumption, good mud scraping effect, small footprint, low cost of use, box-shaped structure, greatly lighter than traditional mechanisms, low operating costs, good economic and social benefits, suitable for popularization and use .

Description

technical field [0001] The invention relates to a mud scraper, in particular to a stirring mud scraper for a clarification tank, which belongs to the field of construction machinery. Background technique [0002] With the development of society and the advancement of science and technology, people's requirements for the quality of life are also constantly improving. The mud scraper is mainly used in circular sedimentation tanks with large diameters in urban sewage treatment plants, waterworks and industrial wastewater treatment to remove the sludge settled at the bottom of the tank and skim the scum on the surface of the tank. The clarifier mixer and mud scraper are the main supporting equipment of the mechanical acceleration clarifier. The mechanical acceleration clarifier is suitable for the clarification treatment of urban drinking water and industrial water, the tertiary treatment of industrial wastewater and the softening treatment of water quality. [0003] The stirri...

AI Technical Summary

Problems solved by technology

[0003] The stirring device and the mud scraping device of the currently used clarifier mixing and scraping device are separately installed, resulting in a large footprint and high production costs, which are far from meeting the needs of users. Moreover, the prior art clarifier mixing The interchangeability of the wearing parts in the mud scraper is poor, the wearing parts are not easy to replace after being damaged, the maintenance and replacement time is long, and the mixing and scraping work of the clarifier is delayed, the rake lifting structure is complex, the rake lifting action is slow during work, and the bending torque The overload capacity is poor, and it is easy to cause damage to the rake lifting and mud scraping parts. Since the oil scraper is installed on the mud scraper and rotates with the rake to scrape oil, this structure brings about poor oil collection effect. Factors such as poor long-term operation stability
