Problems solved by technology

After the thickener has been running for a certain period of time, the center of the bottom of the rake frame will deviate due to reasons such as stress release of various structural parts, which will cause one-sided wear of the limit shaft sleeve and greatly shorten the service life

Abstract

The invention discloses a stepless aligning device for limiting rake frame of thickener. The stepless aligning device comprises a limiting shaft, an upper eccentric seat flange, a lower eccentric seat upper flange, a lower eccentric seat connecting shaft, a lower eccentric seat lower flange, a base flange and a base connecting shaft, and the upper eccentric seat flange is eccentrically connected to the lower end of the limiting shaft; the lower eccentric seat upper flange is eccentrically connected to the upper end of the lower eccentric seat connecting shaft; and the upper eccentric base flange, the lower eccentric base upper flange, the lower eccentric base lower flange and the base flange are each provided with a plurality of kidney-shaped holes evenly distributed in the circumferential direction, and the span angle of each kidney-shaped hole is equal to the gap angle of every two adjacent kidney-shaped holes. By rotating the offset distance and the offset angle of the upper eccentric seat and the lower eccentric seat, the axis of the limiting shaft can be kept concentric with the central axis of the bottom of the rake frame of the thickener, then the limiting shaft or a shaft sleeve arranged on the outer side of the limiting shaft in a sleeving mode is evenly abraded, the phenomenon that one side is rapidly abraded is avoided, and then the service life of the rake frame of the thickener is prolonged.

Description

technical field [0001] The invention relates to the technical field of thickeners, in particular to a stepless centering device used for limiting the rake frame of the thickener. Background technique [0002] The rake frame of the thickener is generally a structure driven by the top suspension. In order to prevent the bottom from being too deflected and interfere with the pool body, a limit seat is usually welded on the bottom of the pool body. After the thickener has been running for a certain period of time, the center of the bottom of the rake frame will deviate due to the stress release of various structural parts and other reasons, which will cause one-sided wear of the limiting sleeve and greatly shorten the service life. Contents of the invention [0003] In view of this, the object of the present invention is to provide a stepless centering device for the limit of the rake frame of the thickener, which can avoid unilateral wear of the limit shaft and ensure its ser...
