Abstract

The invention relates to a magnetic control type full-angle-feeding three-product heavy medium cyclone, belonging to the technical field of coal separation equipment. The heavy medium cyclone comprises a cyclone cylinder and a magnetic control device, wherein the magnetic control device is arranged on the cyclone cylinder and is used for changing weight medium distribution of to-be-separated materials in the cyclone cylinder by virtue of magnetic force traction; the magnetic control device comprises an internal magnetic system and an external magnetic system which are respectively arranged on the inner side and outer side of the cyclone cylinder, and the internal magnetic system and the external magnetic system are respectively electrified to control the magnetic force. The heavy medium cyclone has the beneficial effects that after materials are fed into the cyclone cylinder, traction forces are generated to heavy mediums by virtue of the magnetic forces of the internal and external magnetic systems of the magnetic control device, so that the distribution of the heavy mediums is regulated, the materials are effectively dispersed, and elimination of blockage is facilitated; the stability of suspension liquid is controlled, and the separation time is regulated and controlled; the distribution of separation layers of the heavy mediums is changed, the loss of clean coal is reduced, the yield of the clean coal is improved, a coarse size phenomenon is reduced, and the quality of the clean coal is improved; by arranging a flow guide device, the materials and the medium suspension liquid can be fed in batch along a 360-degree annular direction, so as to realize batch washing selection.

Description

technical field

[0001] The invention belongs to the technical field of coal sorting equipment, and in particular relates to a magnetically controlled full-angle feeding three-product dense medium cyclone. Background technique

[0002] In the coal preparation plant, the three-product dense medium cyclone is one of the indispensable equipment. It mainly uses a single-density resuspension liquid to separate raw coal into three products: clean coal, medium coal, and gangue, so it is called three-product dense medium. Cyclone. According to the use of coal types, there are mainly pressure-feeding type and non-pressure-feeding type, among which the pressure-feeding type three-product dense medium cyclone is widely used in coal preparation plants. The existing pressurized feeding type three-product dense medium cyclone, in actual production, mainly has the following shortcomings:

[0003] 1) The three-product heavy medium cyclone with pressure feeding often appears unstable and th...
