Abstract
This invention concerns magnetic separator comprised by excitation device, which comprises first selection and final selection rollers and usually used as improvement device for that limonite is magnetic selected not be directly but after roasting. For that, the invention employs an excitation device to make ferrum element of iron ore with selective character and improve existing magnet assemble method of general dry type roller. First, gather magnetic contours and export them by given direction; the magnetic contours all act on working magnetic surface of roller and obtain needed iron fine power.
Description
Technical field
The present invention relates to a kind of cylinder dry magnetic separation machinery of forming by permanent magnet.
Background technology
In the at present general prior art, mainly use drum-type washing, dry separation magnetic separator that iron ore is sorted smart powder.But this class machinery can't the magnetic separation limonite.Therefore at the main steel industry that uses this iron ore, build roaster and make the iron ore can magnetic separation, for example Gansu is spilt spring iron company and is just adopted this method.
Since build roaster except that floor space greatly, it builds up this and crosses that impotentia adopts this method in the higher place, and direct loading smelting causes efficient low, yields poorly, and wastes mine resources in a large number, these unreasonable technologies still extensively adopt.
Summary of the invention
The purpose of this invention is to provide a kind of simple structure, the low exitation type magnetic separator that is suitable for medium-sized enterprise's extensive use of cost.
Behind the iron ore breaking and Dusting, utilizing the intensive ferro element of magnetic selection method is that general way problem is iron ore because characteristics of molecular structure own can not magnetic, must take this link of roasting, because above-mentioned roasting needs to increase this process of special equipment in addition and strengthened production cost, make production efficiency corresponding simultaneously in decline.The present invention has taked not change the molecular structure of former mineral and has taked that former ferromagnetics is added one and fill exciting field, its molecule is strengthened by weak magnetic substance magnetic after magnetization promptly can enter magnetic separation.
At first enter primary election, this part also is different from general dry separation magnetic and rolls, for adapting to because the iron ore magnetic property will have the part iron molecule partly to be selected in primary election after excitation, and the iron molecule that is not selected assembles owing to the improved magnet of the structure applications of this part when selecting eventually, and this moment, more weak iron molecule was sent on magnet once more until reaching normal level technology index.By the iron molecule after the excitation is jug-handled, but after primary election and when selecting eventually, be captured at last.This is because the two-part magnetic field alignment in back is through compiling method the magnetic line of force to be compiled, and derives through magnetic sheet, acts on the magnetic cylinder, and the magnetic field of this moment can effectively be adsorbed weak property ferromagnetics.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is made detailed explanation.
Fig. 1 is the structural principle schematic diagram of excitation primary election of the present invention, whole choosing.
The specific embodiment
The described structure of Fig. 1 is by an excitation case (7) and primary election cylinder (6) and the whole magnetic dressing process that selects cylinder (3) to be formed.After ore in sand form is entered by charging aperture (8), at first fall on the excitation case (7).Because going up quilt, (7) had the skin of eccentric wheel and guide rod composition for taking turns (9) institute rotary action on casing, have forward propelling and the active force of vibration force and exciting field, the raw material that contain iron molecule this moment constantly magnetizes and is equipped with in the tube of (6) (6) on the adhesive tape that falls into the primary election cylinder that flows forward after the motion through above-mentioned the magnet through compiling, this magnet is placed at circle and is left 1/3rd magnetic opening, the sand material that falls into adhesive tape drives to the opening part of (6) through the adhesive tape line, iron molecule comes off at this place through reclaiming plate washer (4) retaining in the smart powder case of underpart, not selected mulling flows to eventually through plate (5) and selects on the adhesive tape of cylinder (3), and when moving to the opening part of (6) as described, institute's iron powder that obtains is collected in the smart powder case of stone by guide plate (2), and final tailings is emitted on the casing place through plate (1).
Concrete operation principle of the foregoing description and process are transmission device to be housed in the steel framework bottom it comprises that belt pulley (9) that driving force after motor gear box and belt pulley are speed change at first acts on shelf top goes up (9) and can be decelerated to and eccentric wheel is housed in the required rotating speed wheel and guide rod again by (6) fortune (3) is done synchronously rotation with (9) rotation synchronously through passing to primary election cylinder (6) in order to the belt pulley to excitation case (7) start campaign merit (9) bottom.This moment when the sand material by charging aperture (8) when falling (7) as described above the sand material is filled exciting field, and be transferred to (6) position, this moment, strong magnetic substance was selected, clout continues forward fortune, and partly that weak magnetic substance is selected surplus tailings is finally separated in stronger magnetic field in order to fall into (3).Because (6) are to depend on compiling of the magnetic line of force through the magnetic field intensity of strengthening with the magnetic field of (3), and point to lead to the whole zone of removing opening part it will finally finish have can not magnetic separation ferro element be captured, realized that limonite can non-roasting and magnetic separation.
Claims (3)
1, a kind of machinery that sorts iron ore matter, it comprises that water law wet separation machine and dry type select machine, they all can not be for the Iron Ore Powder magnetic separation in the prior art, for the head it off unique method is with iron ore elder generation's roasting magnetic separation again, but can strengthens the input of equipment factory site like this and takies and can not be widely adopted.The present invention adopts increases an excitation plate (7) when Iron Ore Powder during through this before common apparatus, by after the magnetic field magnetisation by adhesive tape be to the primary election cylinder (6) this moment gathered in the crops another part iron content mixed sand by at first magnetized iron powder by (6) absorption.When fall into when selecting eventually cylinder (3) to go up by special cylinder absorption like this their whole processes be with common magnetic separation approximate (dry-type magnetic extractor) but it is characterized in that (7) thus be can make it become the material that can be adsorbed to magnet matter excitation to be selected.
2, wanting 1 described (6) and (3) according to power is that the magnetic line of force to magnet itself compiles, and it is characterized in that this magnetic line of force ties up on the required working face through magnetic conductor.
3, according to claim 1,2, the excitation that the present invention constituted is compiled, and guiding finally can realize directly magnetic separation of iron ore.
