Description

Hanging harrow thickener device

Technical Field

The utility model belongs to the technical field of hanging harrow concentrators, and particularly relates to a hanging harrow concentrator device.

Background

The thickener is a processing device for concentration production, and is mainly used for concentrating, processing and producing mineral aggregate, specifically for removing water in mineral aggregate pulp after the mineral aggregate pulp is processed in the thickener in a concentration mode. The concentrator is in industries such as coal, mineral separation, steel, chemical industry and other fields.

The rake type thickener is mainly used for cleaning and concentrating mineral aggregate, and the main body structure of the rake type thickener comprises a concentration tank, a cleaning rake frame and the like which are arranged in the concentration tank. In the cleaning process, the rake frame is cleaned to clean mineral aggregate. Specifically, the cleaning harrow frame is used for realizing high-efficiency harrowing, cleaning and harrowing of the material ore pulp in the cleaning and harrowing process.

At present, most of cleaning harrows used by a harrow type thickener are single-layer harrows, the single-layer harrows adopt a plurality of harrow bars, and in the harrow and cleaning process, the single-layer harrow bars can sufficiently harrow ore pulp, but are only suitable for ore pulp at the bottom of the concentration. Specifically, for the ore pulp with large concentration, the ore pulp with large concentration can not be effectively raked and raked in the raking and washing process under the raking rod with a single-layer structure because the ore pulp with large concentration is more in bottom layer sedimentation and the bottom layer concentration is high.

Meanwhile, the single-layer structure rake rod can rake mineral aggregates only, and cannot effectively float up the ore pulp material solution due to turning, so that floating suspended mineral aggregates are thinned, and the concentration effect of the mineral aggregates is improved.
