Deep wimble thickener

Abstract

The invention discloses a deep cone thickener, which comprises a main body, a stirrer device, a drive set, and a circulating system. The main body comprises an upper cylinder part, a cone part which is positioned below the upper cylinder part, and a lower cylinder part which is positioned below the cone part; the stirrer device is arranged in the main body; the drive set drives the stirrer device to rotate so as to stir a ground paste in the main body; and the circulating system is arranged outside of the main body, and makes the lower part of the lower cylinder part be communicated with the upper part of the lower cylinder part and the upper cylinder part respectively, so as to convey the ground paste to the upper cylinder part and / or the upper part of the lower cylinder part from the lower part of the lower cylinder part. The deep cone thickener has an upper and lower dual circulating system, has an arch breaking effect to prevent raker holding when in the upper circulating, and can accelerate sedimentation of the ground paste in the cone part when in the lower circulating, so as to achieve the effect of fast concentration and improve thickening efficiency.

Description

technical field [0001] The invention relates to a mining equipment, in particular to a deep cone thickener. Background technique [0002] Thickeners are mining equipment widely used in the field of mineral processing, for example, thickeners can be used to thicken the tailing slurry of the dressing plant. The diameter of traditional thickeners is generally larger than its height, for example, the diameter can reach 100 meters, while the diameter is 10 meters, so the cone angle is larger. The diameter of the deep cone thickener is generally smaller than its height, for example, the diameter is 11 meters and the height is 20 meters. Therefore, the cone angle is small and the cone is relatively deep. [0003] Traditionally, when the deep cone thickener is not discharging, in order to prevent tailings from depositing at the bottom of the thickener, a circulation system is usually set up to drive the underflow slurry from the bottom of the deep cone thickener to the top feed por...

Problems solved by technology

[0003] Traditionally, when the deep cone thickener is not discharging, in order to prevent tailings from depositing at the bottom of the thickener, a circulation system is usually set up to drive the underflow slurry from the bottom of the deep cone thickener to the top feed port of the thickener. Therefore, the underflow slurry entering the deep cone thickener from the top feed port is concentrated again together with the tailing slurry from the dressing plant, which requires a longer concentration time and reduces the concentration efficiency

In addition, because the underflow slurry is driven to the top feed port of the thickener, the tailing sand deposited near the rake frame of the deep cone thickener is easy to arch, and the phenomenon of rake pressure will occur, so that the material cannot be discharged stably and is easily damaged. rake frame
