Single different diameter multi-product dense medium cyclone

Abstract

The invention relates to a dense medium cyclone for monomer different-diameter products. The dense medium cyclone comprises cylindrical sections, a circular cone section, a concentric overflow pipe, a feeding port and a bottom flow port, wherein at least two cylindrical sections in different diameters are arranged; the circular cone section is butt-jointed with the bottom of the cylindrical section with the smallest diameter; two or more cylindrical sections in different diameters are connected through diameter-changing structures; through the diameter-changing structures, the materials and suspension liquid can enter into the next cylindrical section from the previous cylindrical section along a tangential direction; low-density material and high-density material can be acquired by adopting one cylindrical section for sorting; the low-density material is drained from the overflow pipe on the outer side; the high-density material stably enters into the next cylindrical section along the tangential direction through the diameter-changing structures and is sorted on the next cylindrical section; the middle-density material product is drained from the overflow pipe on the outer layer; the high-density product enters into the next cylindrical section and is sorted or drained from the bottom flow port. The dense medium cyclone for monomer different-diameter products has the advantages of compact structure, convenience in mounting, capability of sorting multiple products from one density material and suitability for the users having different coal quality requirements.

Description

technical field [0001] The invention relates to a dense medium cyclone, in particular to a single-different-diameter multi-product heavy-duty cyclone which uses a connection transition device to connect a plurality of cylinders with different diameters and cooperates with a concentric overflow pipe structure to realize the separation of various products. Media cyclone. Background technique [0002] At present, the dense medium cyclone has been widely used in the separation of the coal industry. The common two-product dense medium cyclone is usually a cylindrical conical cyclone. The raw material and suspension enter the interior of the cyclone from the feed inlet, the overflow produces low-density grade products, and the bottom flow obtains high-density grade products. However, the common three-product dense medium cyclone is often just another two-product cyclone connected in series on the original two-product heavy medium cyclone through pipelines; to obtain more sorting ...
