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

Embodiment Construction

[0010] The specific details and working conditions of the present invention will be described below in conjunction with the accompanying drawings of the description.

[0011] The working conditions of the large-scale flexible lifting rake central drive mud scraper of the present invention are as follows: the ore pulp or sewage enters the radial flow after being stabilized by the feeding steady flow tube (16) from the water inlet pipe (3) suspended under the truss (2) Sedimentation tank (15), containing 2-4 cycloidal planetary gears for over-torque protection and torque display. The output shaft of the planetary gear drive (1) is equipped with a pinion (18), and the external teeth of the pinion (18) are connected to the slewing support ( The inner teeth of 17) mesh and drive the rotation of the slewing support (17), driving the center tumbler (8) just connected to the slewing support (17), the torque arm (4), and the mud scraper (13), so that the rotating torque The arm (4) and...

Abstract

The invention discloses a large central transmission sludge scrapper with flexible lifting rakes, which is used for sludge treatment of environmental protection and essentially comprises a 2 to 4 cycloids planetary gear drive device (1) with overtorque protection and torque display, a truss (2), a water inlet pipe (3), a rotary torque arm (4), an overflow weir (5), an water outlet pipe (6), a hinged joint (7), a central rotary cage (8), an oil collector (9), an oil scrapper rake (10), an oil outlet pipe (11), steel wire ropes (12), a sludge scrapper rake (13), a sludge discharge outlet (14), a truss radical sedimentation basin (15), a feeding steady flow tube (16), a rotary support (17), a pinion wheel (18), etc. The large central transmission sludge scrapper of the invention can realize the transmission of high torque and guarantee the effect of sludge scrapping, high-efficiency and stable operation, and is particularly applicable to a large radial sedimentation basin with the diameter equal to or more than 45 meters.

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...
