Abstract

The invention relates to a novel central feeding cylinder of a thickener. The novel central feeding cylinder comprises a cylinder, a feeding pipe, a baffle plate and a fixed ear plate; the feeding pipe stretches into the central feeding cylinder in the tangential direction of the cylinder in a manner of forming a downward tilt angle of 2 degrees to 3 degrees; the baffle plate perpendicular to the tangential direction of the inner wall of the cylinder is welded on the inner wall of the central feeding cylinder, so as to enable inlet ore slurry to flow through the baffle plate perpendicular to the inner wall of the central feeding cylinder, air emission can be promoted and surplus energy can be dissipated effectively, and the mixing efficiency can be improved; the ore slurry entering the central feeding cylinder can produce turbulent flow after meeting the baffle plate, so as to facilitate the full mixing of the ore slurry and a flocculating agent, therefore, relatively large floccules are formed, the dehydration effect can be improved, and the work efficiency of the thickener can be improved.

Description

technical field

[0001] The present invention relates to the technical field of solid-liquid separation, and in particular to a central feeding barrel of a thickener. Background technique

[0002] A thickener is a solid-liquid separation device based on gravity settlement. It is usually a shallow cylindrical tank with a conical bottom built from concrete, wood or metal welded plates as structural materials. It is divided into ordinary thickeners and high-efficiency thickeners. After the ore feed of the thickener is mixed with the flocculant, it enters the thickener through the central feeding cylinder, thereby performing a series of settling and separation actions. At present, the method of direct feeding is usually adopted to enter the central feeding cylinder of the thickener, but there are problems of unsatisfactory sedimentation effect and poor concentration effect. Because there are still many air bubbles in the pulp entering the thickener in this way, solid particles a...
