Problems solved by technology

[0002] At present, there are problems with the rake lifting device of the existing central drive mud scraper: 1. The rake lifting mechanism is complicated, the rake lifting action is slow, and the stability is not high
2. The ability to resist large torque and overload is poor. The rake lifting and mud scraping equipment form a rigid whole, and the rake lifting and mud scraping mechanisms are easily damaged.
3. The oil scraping rake is installed on the mud scraper, scraping oil with the mud rake rotation, the oil collection effect is not stable

Abstract

The invention discloses a large-scale flexible rake-lifting center-driven mud scraper for environmental sludge treatment, mainly composed of 2-4 cycloidal planetary gear drive devices (1) truss (2) with over-torque protection and torque display ) Inlet pipe (3) Rotating torque arm (4) Overflow weir (5) Outlet pipe (6) Articulation point (7) Center tumbler (8) Oil collector (9) Oil rake (10) Oil outlet pipe (11 ) steel wire rope (12) mud scraper (13) mud outlet (14) truss radial flow sedimentation tank (15) feeding steady flow cylinder (16) slewing support (17) pinion (18) and other components, which can realize the transmission of large The torque ensures the mud scraping effect, and the operation is efficient and stable. It is especially suitable for large radial flow sedimentation tanks with a diameter of 45 meters and above.

Description

technical field [0001] The invention relates to a water treatment system in the fields of environmental protection and mineral processing, which is used for scraping and concentrating sludge and ore pulp, and is a large-scale flexible rake-lifting center-driven mud scraper for clarification medium. Background technique [0002] At present, there are problems in the rake lifting device of the existing central drive mud scraper: 1. The rake lifting mechanism is complex, the rake lifting action is slow, and the stability is not high. 2. The ability to resist large torque and overload is poor. The rake lifting and mud scraping equipment form a rigid whole, and the rake lifting and mud scraping mechanisms are easily damaged. 3. The oil scraper rake is installed on the mud scraper, scrapes oil with the mud rake rotation, and the oil collection effect is unstable. Contents of the invention [0003] The purpose of the present invention is to effectively overcome the above-mention...
