Abstract
The invention relates to a magnetic reselection device, in particular to an electromagnetically-focused concentration machine for concentrating magnetite, which comprises an ore supply hopper, an ore supply pipe, a tailing overflowing groove, a separation bucket, excitation coils, a water supply package, an ore concentrate funnel and an ore concentrate discharge valve. The separation bucket is internally provided with a plurality of layers of excitation coil with a waterproof ware-resistant protection layer from top to bottom by a bracket, the excitation coil at the upmost layer supplies a constant direct current, other excitation coils are grouped and sequentially switched on with the switching-on time and currents automatically or manually adjusted according to the overflowing density and the separation conditions, the upper part of the separation bucket is provided with a tailing overflowing density sensor, and an ore concentration density sensor is arranged between the ore concentrate funnel and the ore concentrate discharge valve at the bottom of the separation bucket. In machine, the utilization rate of the magnetic field is greatly improved, and lower-cost iron materials can be adopted for the separation bucket. By the aid of the control of the ore concentrate discharge valve, the circulating time adjustment of the separation magnetic field and the automatic control of the field strength, the aims of decreasing the manufacture cost of the device, saving the energy and ensuring the optimal separation effect are achieved.
Description
Technical field
The present invention relates to the magnetic gravitational separation equipment, specifically a kind of Electromagnetically-focused concentration machine that is used for selected magnetic iron ore.
Background technology
At present, the gravitational separation equipment in magnet ore dressing plant adopts magnetic coagulation gravity separator, magnetic separation post etc. more.Its magnetic field of magnetic coagulation gravity separator is produced by permanent magnetism material in the sorting bucket, and magnetic field is fixed, and is difficult for adjusting, and separating effect is relatively poor.Its magnetic field of magnetic separation post is produced by sorting bucket exterior loop, can regulate magnetic field and replace period of change and magnetic field intensity, and separating effect is better, but have only part magnetic field to enter in the sorting bucket, the magnetic field utilization rate is low, and the sorting bucket need adopt the non-magnetic stainless steel material, the cost height, power consumption is more.The ore discharge valve is controlled automatically and magnetic field intensity is controlled automatically though increased on the magnetic separation column foundation thereafter, the coil conduction mode improves to some extent, and has formed a series of refiners, but coil is put in separation tube outer structure and no change, still exist the magnetic field utilization rate low, the problem that cost is high.
Summary of the invention
The present invention is intended to solve present electromagnetism and selects kind equipment generally coil to be put in outside the separation tube, and the magnetic field utilization rate is low, problems such as cost height, thus a kind of Electromagnetically-focused concentration machine of internal coil is provided.
The technical scheme that realizes the object of the invention is: a kind of Electromagnetically-focused concentration machine; comprise mine feeding bucket and mineral-feeding pipe, mine tailing overflow launder, sorting bucket, magnet exciting coil, feedwater bag, concentrate funnel, concentrate ore discharge valve, be provided with magnet exciting coil in the described sorting bucket with waterproof antiwear damage protective layer.
Further, technical scheme of the present invention is: the built-in magnet exciting coil of described sorting bucket multilayer is from top to bottom arranged, each layer magnet exciting coil all installs and fixes by the bucket inner support, the magnet exciting coil of the superiors is for supplying with the magnet exciting coil of constant dc, all the other are conducting successively, ON time and the size of current magnet exciting coil with overflow density and the adjusting of sorting situation automatic or manual that divides into groups, mine tailing overflow density sensor is equipped with on sorting bucket top, between the concentrate funnel of sorting bucket bottom and the concentrate ore discharge valve concentrate density sensor is housed.
The present invention compared with prior art has following four new features:
1. built-in magnet exciting coil: in the sorting bucket, place magnet exciting coil and produce magnetic field, magnetic field acts in the sorting bucket to greatest extent, is positioned over the sorting bucket with coil and compares outward, and magnet exciting coil magnetic field utilization rate improves greatly, reduce equipment manufacturing cost, and realized energy-conservation purpose.
2. magnet exciting coil has waterproof antiwear damage protective layer: because magnet exciting coil is put in the sorting bucket, soak and wearing and tearing so coil should be able to bear ore pulp.Must do waterproof antiwear to magnet exciting coil for this reason and decrease processing; processing method can be: conventional dipping lacquer, stainless steel parcel, poured with epoxy resin are reinforced; also can conventional dipping lacquer, rubber processing, its lead-in wire adopts rubber cable also to wrap up the adhesive tape abrasionproof and handles, and adds the sheath protection.
3. the sorting bucket can adopt common ferrous material: because magnet exciting coil places in the sorting bucket, so the sorting bucket do not need to adopt the non-magnetic stainless steel material, and common ferrous material can meet the demands, thereby can reduce cost greatly.
4. coil can adopt the safe voltage power supply: power supply can adopt the control transformer power supply, is depressurized to safe voltage, and has played buffer action, is controlled by cyclelog and control circuit, has guaranteed Personal Safety.
