Abstract

The utility model discloses an electromagnetic jigged iron powder grade improver which comprises a material inlet, a hopper, a filter net, an overflow box, a connection device, a sorting bucket, a jigging device, a conical material outlet, a numerically controlled valve, an annular water feeder, an electromagnetic device and an overflow pipe, wherein a density sensor is arranged on the outer side of the hopper; the jigging device comprises a jigging execution device and a linear transmission device; and a density sensor is arranged on the outer side of the conical material outlet. The improver loosely layers sorted materials by using unique pulse water flow according to a reselection theory in a pulse-adjustable electromagnetic field, so that substances such as gangues, nonmagnetic substances, coenobiums and the like are completely separated from magnetite under the actions of a magnetic force, the gravity and the pulse water flow, and an aim of improving the grade of iron refined powder is fulfilled.

Description

Electromagnetism jigging iron powder grade elevator

Technical field

The utility model relates to a kind of preparation equipment, relates in particular to the equipment that under a kind of effect through pulse magnet field force, gravity and pulse current the gangue namagnetic substance is separated with magnetic iron ore.

Background technology

Traditional magnet ore deposit picking equipment comprises low-intensity (magnetic) separator, magnetic coagulation gravity separator, magnetic accumulating machine etc.

When adopting low-intensity (magnetic) separator the microfine iron ore to be handled as picking equipment; Because fine-particle minerals is mingled with gangue in reuniting; Especially to some than magnetizing system height and the thinner magnetic iron ore of disseminated grain size; Even carry out repeatedly selectedly, also be difficult to improve the grade of iron ore concentrate, almost powerless especially for the situation that requires iron concentrate grade to reach more than 68%.

Its magnetic field of magnetic coagulation gravity separator is to be produced by permanent magnetism material in the sorting bucket, and magnetic field is fixed, and is difficult for adjustment, and separating effect is relatively poor.

The magnetic field of magnetic separation post is produced by sorting bucket exterior loop, can regulate magnetic field alternate cycle and magnetic field intensity, and separating effect is better; But have only part magnetic field to get in the sorting bucket, the magnetic field utilization rate is low, and it is limited to improve the concentrate grade amplitude; Problems such as water consumption is big, and overflow is of high grade, and the efficiency of separation is low.

The utility model content

The utility model provides a kind of preparation equipment; This equipment utilization gravity treatment principle; Be aided with adjustable pulse electromagnetic field and utilize exclusive pulse current; Sorting material is carried out loose layering, materials such as gangue, namagnetic substance and intergrowth and magnetic iron ore are fully separated by overfall discharge, magnetic iron ore is discharged by bottom concentrate mouth reach the purpose that improves the smart grade powder of iron.

The utility model provides a kind of electromagnetism jigging iron powder grade elevator, and this elevator comprises: charging aperture, and hopper, screen pack, spill box, jockey sorts bucket, jig plant, conical discharge port, digital controlled valve, ring-like feed feeder, calutron, overflow pipe.

As preferred version: density also is installed on the wherein said hopper passes filter.

As preferred version: wherein said jig plant comprises jigging actuating unit, linear transmission.

As preferred version: density sensor also is installed on the wherein said conical discharge port.

Charging aperture in the electromagnet grade powder elevator, hopper, screen pack, spill box are formed the feeding system of elevator; Feeding system is used for carrying out the material that is provided eddy flow, buffering, concentrate and filtering; Discharge through the form of rotating then, thereby reach purpose slow, even feeding.

Jockey in the electromagnet grade powder elevator is used for feeding system and sorts bucket closely linking together.

Sorting in the electromagnet grade powder elevator is equipped with calutron in the bucket; Said calutron is installed in through support from bottom to top by many groups magnet exciting coil and sorts in the bucket; Can carry out reasonable conducting according to different iron powder character, and can adjust the magnetic field intensity that is produced, this calutron is provided with the insulation of four roads, water-proof protection device; And it is, safe and reliable through the withstand voltage experiment test of 2500V.

Jig plant in the electromagnet grade powder elevator is erected at and sorts the bucket outside; It can produce the mechanical force rectilinear motion through the electromagnetism conduction, has changed the crank type kinds of drive such as jigging machine, reduces the friction of machine components; Owing to do not have the effect of bent axle power, bearing etc., thereby reduced fault rate.

Conical discharge port in the electromagnet grade powder elevator is used for discharging, and digital controlled valve is used to control the speed of discharging.

Annular feed feeder in the electromagnet grade powder elevator is used to ensure even feedwater, to reach the steady of feedwater.

Overflow pipe in the wherein said electromagnet grade powder elevator is used for discharging the impurity substances of concentrate.

During the work of electromagnet grade powder elevator; Material to be selected gets into hopper by charging aperture, gets into spill box through behind the strainer filtering, gets into then to sort in the bucket; Wherein calutron control coil generation excitation is carried out sorting; Produce the uniform flow by jig plant simultaneously and carry out sorting, annular feed feeder provides reconcilable ring-like current, and makes the concentrate impurity of discharging through the taper material rise to spill box and discharge.

Compared with prior art, the beneficial effect of the utility model mainly shows the following aspects:

(1) improves magnetic powder grade 2%-7%;

(2) content of impurity such as the sulphur in the reduction magnetic powder, phosphorus, silicon;

(3) electric-control system adopts electronics watch dog monitoring mode, has realized that automatic detection sorts district's pulp density and timely adjustment valve opening guarantees that overflow is reliable and stable, can reconcile the magnetic field intensity that sorts the district automatically, makes the ore dressing effect more stable;

(4) control system adopts the microcomputerized control mode, has changed the drawback of contact demodulator, makes the stability of a system more reliable;

(5) compact conformation, reasonable in design, floor space is little, and technological process is simple;

(6) applicability is extensive, can be used for the selected of multiple mineral aggregate.
