Description

A kind of mine iron sorting machine

Technical field

The present invention relates to mineral products objects to remove iron field, more particularly to contains magnetizable particles in ore pulp, takes electromagnetism point Field from means.

Background technology

Existing mineral products object magnetic separator de-ironing generally draws magnetizable particle in minerals, this mode using permanent magnet The deficiency being primarily present is that iron content composition is still larger in finished product minerals after processing, the yield for the finished product in addition processed It is small.Also take after mixing minerals and water into ore pulp, iron remove using magnetic separator, this mode at work, by Speed when ore pulp enters magnetic separating unit, impulse force is bigger, can take away the magnetized particles being sucked by magnetism, therefore efficiency It is relatively low.

Invention content

In view of the shortcomings of the background art, the technical problem to be solved in the present invention is to provide a kind of mine iron extension set, substeps Suddenly minerals and magnetizable particles are separated.

For this purpose, the present invention is adopted the following technical scheme that solve above-mentioned technical problem：

A kind of mine iron sorting machine, including sealing shell 6, holder 7, magnetic conduction grid 5, lower end inlet and outlet 19, upper end inlet and outlet 29, mine cavity 1 and cooling chamber 2, feature further include electric control system, have sealing between the mine cavity and the cooling chamber Cage ring 4, the magnetic conduction grid are located at center, and outer ring has the sealing separation ring, in the sealing separation ring There is coil 3, the sealing shell to be made by permeability magnetic material outside, field circuit is provided for the coil 3；With short-circuited conducting sleeve 8, which, can also be by the short-circuited conducting sleeve 8 and described close between the magnetic conduction grid and the coil Envelope cage ring 4 is combined into one structure；Under the described lower end inlet and outlet connection to mine valve 12, mine valve 11, lower iron exhaust valve next time Door 17；The upper end inlet and outlet connect upper ore removal valve 22, upper inlet valve 21, upper air valve 27；The upper end into The upper iron exhaust valve door 28 of outlet connection, lower end inlet and outlet connect lower inlet valve 18；When except iron, the coil 3 is powered, Enter from feed port 13, come out from mine mouth 23 is gone out to mine valve 12 and upper ore removal valve 22, ore pulp under only opening；When arranging iron, institute The coil 3 stated powers off, and only opens upper inlet valve 21 and lower iron exhaust valve door 17, clear water enters from upper water inlet 24, from lower row's iron Mouth 16 comes out；Or when being to arrange iron, lower inlet valve 18 and upper iron exhaust valve door 28, clear water are only opened in the coil 3 power-off Enter from lower water inlet 15, is come out from upper row's iron mouth 25；When returning mine, the coil 3 does not power off, and only opens mine valve 11 next time With upper inlet valve 21, clear water enters from upper water inlet 24, is come out from mine mouth 14 next time；Or when being back mine, the line Circle 3 does not power off, and only opens mine valve 11 next time and upper air valve 27, and compressed air enters from mouth 26, and ore pulp is from mine mouth next time 14 come out；The electric control system includes rectified three-phase circuit, the rectified three-phase circuit export direct current with it is described Coil electrical connection, the valves of above-mentioned various titles all opens or closes by the electric control system execution；

A kind of mine iron separation system, including with ore pulp synthesis unit, ore pulp particle screen selecting unit, finished product sedimentation basin, It is characterized by having above-mentioned mine iron sorting machine.

In the present invention, the sealing shell 6 that permeability magnetic material makes, not only as the shell of machine, but also can be as the line The field circuit of circle kills two birds with one stone, and unexpected have technical effect that is enhanced by the magnetism intensity on magnetic conduction grid；It leads Magnetic grid 5, the magnetic conduction grid are to form the small cavity in gap after being superimposed by several permeability magnetic materials to synthesize, and can take wire netting Stacking is got up, and centre forms countless small spaces composition mine cavitys 1, magnetizes under the action of the coil is powered, magnetic conduction Iron wire, which magnetizes, magnetic north-south, ore pulp by when, magnetizable fine particle is adsorbed in iron net, and magnetic conduction network can also be adopted With little particle permeability magnetic material, effect is same as above；Mine is discharged when ore pulp enters cavity, returns mine when for work in lower end inlet and outlet 19 Slurry, row iron when water inlet and row iron when export；Upper end inlet and outlet 29 are used for finished product mine discharge cavity, row's iron when work or return mine When water inlet, return mine when water inlet or air inlet, and row iron when export；Cooling chamber 2 can be used for the coil work with filling liquid It generates heat and radiates when making, external heat exchange unit takes heat outside machine out of；

The electric control system includes rectified three-phase circuit, the rectified three-phase circuit export direct current with it is described Coil electrical connection, the valves of above-mentioned various titles all opens or closes by the electric control system execution；Described is automatically controlled System processed further includes built-in microcomputer controller or PLC controller, control each valve on off state realize except ironworker makees, It returns miner to make, along the periods work such as inverse row ironworker work, can also realize that AC power rectification obtains direct current, pass through electronic switch Power supply supply is realized to the coil, can be realized and the coil is supplied with the conducting dutycycle of regulation electronic switch Electric current be adjusted；

There is sealing separation ring 4, the magnetic conduction grid to be located at center between the mine cavity and the cooling chamber, Outer ring has the sealing separation ring, has the coil 3 outside the sealing separation ring, the sealing shell is by leading Magnetic material makes, and field circuit is provided for the coil 3；Also there is short-circuited conducting sleeve 8, the short-circuited conducting sleeve can be made of copper or aluminum material At barrel-shaped, the flat outside for being wound on the sealing separation ring of enameled wire, the short circuit end to end of the enameled wire, the short-circuited conducting sleeve can also be used When the coil is powered, the inverse electromotive force that magnetic field intensity generates during rising carries out short circuit, makes the coil current Quickly reach steady state；When the coil blackout, the electromotive force that magnetic field intensity generates during declining carries out short circuit, this is short The time that Lu Huanneng makes magnetic field intensity rise or fall is short, improves machine service efficiency；The short-circuited conducting sleeve is located at the magnetic conduction Between grid and the coil, the short-circuited conducting sleeve 8 and the sealing separation ring 4 can also be combined into one structure, i.e., It is made for the seal isolation coil structures and using copper product or aluminum material, reduces machine cost of manufacture；

The present invention, as a result of electromagnetic technique, magnetic conduction grid has the magnetic and magnetic conduction when arranging iron when except ironworker makees Grid it is nonmagnetic, conveniently realize being sucked or discharge to magnetized particles, the cost of making machine substantially reduces, working efficiency It greatly improves, there is substantive distinguishing features outstanding and significant progress compared with the prior art.
