Anti-deposition low-resistance rake frame

Abstract

The invention discloses an anti-deposition low-resistance rake frame, and belongs to the technical field of thickener rake frames.The anti-deposition low-resistance rake frame comprises a rake body and rake teeth; the multiple rake teeth are fixed on the bottom surface of the rake body at equal intervals; the rake body is of a hollow metal shell-shaped structure; the rake body is composed of a first long connecting rake, a second long connecting rake and a short connecting rake; one end of the first long connecting rake is fixedly connected with one end of the second long connecting rake; the first long connecting rake and the second long connecting rake form a sample setting out object; and the size of the end face of the end, away from the second long connecting rake, of the first long connecting rake is larger than that of the end face of the end, away from the first long connecting rake, of the second long connecting rake; and one end of the short connecting rake is fixedly connected with one end, far away from the first long connecting rake, of the second long connecting rake. The rake body is of the hollow metal shell-shaped sealed structure; and when the rake body works, the rake body can bear larger buoyancy, so that the rake body floats out of a deposition layer, and therefore, the resistance brought by the deposition layer when the rake frame rotates is reduced.

Description

technical field [0001] The invention belongs to the technical field of thickener rake racks, in particular to an anti-sedimentation low-resistance rake rack. Background technique [0002] A thickener is a solid-liquid separation device based on gravity settling. It is usually a shallow cylindrical tank with a conical bottom built from concrete, wood or metal welded plates as structural materials. The ore pulp with a solid weight of 10% to 20% can be concentrated by gravity sedimentation into an underflow pulp with a solid content of 45% to 55%. ) rake, so that the thickened underflow slurry is discharged from the underflow port at the bottom of the thickener. [0003] The upper part of the thickener produces a relatively clean clarified liquid (overflow), which is discharged from the annular chute at the top. [0004] Thickeners are widely used in hydrometallurgy, mineral processing plants, chemical plants and other production sites that require solid-liquid enrichment and...
