Abstract
Provided is a column magnetic separator, which belongs to mine-selecting facilities, and comprises a feeding hopper, an ore-feeding pipe, an overflow groove, a sorting column, a door magnetic field, a circulating magnetic field, a feed pipe, a bottom drum, a concentrate discharging pipe, a valve and a control power supply. The column magnetic separator is characterized in that the sorting column inner cavity is provided with steady flow plates which are staggered up and down between the door magnetic field and the circulating magnetic field. The column magnetic separator is advantageous in that steady flow plates are disposed between the door magnetic field and the circulating magnetic field, and by means of a mechanical device, the flow of pulp in the center of the column magnetic separator changes from tangent rise to linear rise; pulp flow speed is reduced; the influence on the sorting of the column magnetic separator due to eddy flow generated by the tangent rise of pulp can be eliminated.
Description
Technical field:
The utility model belongs to the ore dressing facility, is specifically related to a kind of magnetic separation post.
Background technology
The magnetic separation post is that the weak magnetic gravitational separation equipment that the participation of magnetic function sorts is taken off in a kind of utilization, is used for the lifting of iron and steel industry mine magnetic mineral grade and the increase of output in recent years.Be the regeneration product of drench pit, magnetic coagulation, electromagnetism refiner, give under the condition of ore deposit, Duo the raising concentrate grade more than 0.8% than drench pit sorting equipment etc. equal.
Fig. 1 is the structure chart of existing magnetic separation post.It is that valve, control power supply are formed by batch meter and mineral-feeding pipe, overflow launder, sorting post, door magnetic field, circulation magnetic field, feed pipe, pucking, concentrate ore discharge pipe.
In the process that sorts; Ore pulp gets into from feed hopper and sorts in the cylinder; Tangent line feedwater through feed pipe forms eddy current, and ore pulp is sorted under different magnetic field, because ascending current sorts flow velocity instability in the cylinder at the magnetic separation post; Cause the magnetic separation post to sort a series of problems such as efficient is low, mainly show the following aspects:
1, magnetic separation post tangent line rises for water generates eddy current spiral; Cause rising on the edge hydraulic pressure mineral are produced bigger buoyancy; Because the alternately magnetic field active force that mineral receive in magnetic separation post core barrel is invariable; The qualified fine grained mineral stronger current that are easy to risen are taken out of, thereby the higher magnetic separation post of chats grade productive rate descends.
2, the eddy current of magnetic separation post causes the center to produce air column, magnetic separation post body mid portion magnetic field intensity a little less than, the magnetic mineral chain is not in time taken off the strong effect in magnetic and circulation magnetic field, causes gangue directly to get into concentrate, product quality reduces.
3, in the operation of magnetic separation post because concentrate grade is low, concentrate underflow valve event is frequent, stifled ore deposit loses the magnetic separation post and sorts function when serious, concentrate underflow valve, sensor, pinch valve equivalent life reduce.
4, other negative effect: magnetic separation post productive rate is low to cause the on-the-spot water yield to regulate increase, and water system is uneven, and the chats amount increases, and increases chats and concentrates magnetic separation board number.
Summary of the invention:
In order to overcome the deficiency of above-mentioned prior art, solve the low problem of magnetic separation post concentrate yield, the utility model provide a kind of simple in structure, cost of manufacture is low, be prone to make effective magnetic separation post selecting device.
The utility model is by batch meter and mineral-feeding pipe, overflow launder, sorting post, form door magnetic field, circulation magnetic field, feed pipe, pucking, concentrate ore discharge pipe and valve, control power supply; It is characterized in that sorting post inner chamber installation stabilier; Stabilier is staggered up and down to be installed between door magnetic field and the circulation magnetic field; Stent support is used in the stabilier bottom, an end of support and the mineral-feeding pipe welding of giving the ore deposit funnel.
The material of said stabilier is non-magnetic conductor, such as the PVC plate;
Said stabilier be shaped as the fan-shaped of 180-210 degree, and the circular hole of the 18-25mm same apertures of evenly gathering in the above.
The utility model adds stabilier in the middle of door magnetic field and circulation magnetic field; Utilizing mechanical device to make magnetic separation post center flow of slurry change into straight line to being risen by tangent line rises; Reduce flow rate of pulp, eliminated the eddy current that produces because of the rising of ore pulp tangent line sorts process to the magnetic separation post influence.
The tangent line that the utility model can utilize mechanical device to suppress the magnetic separation post is effectively given the eddy current of water generates, and equal conditions improves the productive rate of magnetic separation post down, reduces the consumption of water, prolongs the life cycle of YE and sensor, reduces maintenance cost.
