Hydrocyclone with teeter bed separator (TBS) cyclone water curtain separation tank

Abstract

The invention belongs to the technical field of solid-liquid separation equipment, and particularly relates to a hydrocyclone with a teeter bed separator (TBS) cyclone water curtain separation tank. The hydrocyclone with the TBS cyclone water curtain separation tank comprises a hydrocyclone body; an underflow orifice of the hydrocyclone body is connected with the TBS cyclone water curtain separation tank; and the TBS cyclone water curtain separation tank is hung under the underflow orifice through a sealed hanging device. The hydrocyclone with the TBS cyclone water curtain separation tank has the beneficial effects that (1) the classification process and the separation process are integrated, on the one hand, the classification efficiency of the hydrocyclone is improved, and the phenomena of overflowing and unqualified coarse fractions are reduced, so that the clean coal precision is guaranteed; on the other hand, underflow of the hydrocyclone body is further subjected to separation through a cyclone water curtain and a TBS, the problems that underflow is high in ash content and carries fine silt are solved, and separating precision is improved; (2) the hydrocyclone is obtained by optimizing the structure of a water medium cyclone, and the hydrocyclone has the advantages of being simple in structure, convenient to operate and maintain, small in occupied space, high in treatment capacity, low in energy consumption and the like.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation equipment, and in particular relates to a cyclone with a TBS swirling water curtain sorting box. Background technique [0002] In the existing coal preparation process, coarse-grained coal (>1mm) can achieve good separation effect by dense medium or jigging separation, and coal slime (<0.5mm) can achieve ideal separation accuracy by flotation , Only the 0.5~1.0mm coarse coal slime between the effective separation lower limit of the dense medium cyclone and the effective separation upper limit of flotation lacks general separation equipment, and effective separation cannot be achieved. [0003] Among the existing coarse coal slime separation equipment, the separation accuracy of the coal slime dense medium cyclone is high, but the medium recovery efficiency is low, and the medium consumption remains high; the spiral separator can only be obtained when it is separated by high d...
