Description
Garden awl magnetic separator is widely used in metal or nonmetallic mineral dry-type separation (enrichment magnetisable material or eliminating magnetisable material), as ore dressing industries such as black, non-ferrous metal ore, nonmetallic mineral purifications, belongs to the magnetic plant technical field.
There are 40 kinds of forms in the magnetic system of the magnetic separator of present industrial application.Wherein the first to the 36 kind, see Appendix 1,2, (mechanical engineering manual) the 11 volume, July nineteen eighty-two Beijing front page; The 37 to the 40 kind is emerging in the world in recent years magnetic system, and the 3(that sees Appendix selects from the national preparation equipment meeting of holding in Beijing in November, 1989, is announced by＜benficiation machinery〉1989.3 of Shenyang Mining Mechanical Research Institute's writing).
The first to the 36 kind is common magnetic system, familiar, no longer superfluous here chatting.
Problems such as the 37 kind of form is the rotor structure heaviness of the people such as high Kai Erbahe of the big vast fort of federal moral company at existing Jones's type existence, and magnetic circuit is long are invented, and now patent.
The 38 kind of form is Britain GH Jones nineteen eighty-two patent (US4455228) at U. S. application.This invention comes down to not change the coil winding mode on the basis of Jones's machine of former design and manufacturing, has only just set up separation ring.
A kind of novel permanent magnetic high gradient magnetic separator that the 39 kind of form introduced in the 15 international ore dressing meeting by the B.Arvidson of the Bateman equipment company of the U.S..The principal character of this machine is to adopt Nd Fe B alloys novel permanent magnetic body, and magnet is distributed in the dielectric ring both sides, and each iron tyre dielectric ring disposes two pairs of magnets altogether, and the magnetic field that magnetic system produces is horizontal direction.
The 40 kind of form is by the invention of the Soviet Union homemade coal preparation machine research institute, and on March 7th, 1986, the Soviet Union found to have ratified this invention with the invention committee.The unique distinction of the three-ring type intensity magnetic separator of this design is: make full use of leakage field, set up a separation ring, reclaim the ferromagnetism thing in the feed, to get rid of the influence of ferromagnetism thing to its equipment operating efficiency, its advantage is only to use just strong, the weak magnetic mineral of enrichment simultaneously of an equipment.Being different from flat ring type magnetic separator wants two coordinative composition of equipments uses just this function can be arranged.This three-ring type intensity magnetic separator is applied among the wet type ore-dressing practice.
It is serious that the major defect of the dry-type magnetic extractor of present domestic use such as disc type, roll-type magnetic separator is that magnetic system design falls behind leakage field, and the magnetic flux utilization rate is low, only be usually 27～33% thereby consumes energy more relatively; It is few to sort working face, and productivity ratio is low, and the weight of machine is heavier relatively, and the productivity ratio that the unit machine is heavy is lower.
The purpose of this utility model provides a kind of novel garden awl magnetic separator, and it is applied to the dry type ore sorting operation.Can overcome the shortcoming of above-mentioned existing disc type, roll-type magnetic separator.
Accompanying drawing 1 is the front view of garden awl magnetic separator structural representation, and accompanying drawing 2 is the vertical view of structural representation, and accompanying drawing 3 is a schematic diagram for magnetic.Garden awl magnetic separator is made up of following several parts: feed bin (1), hollow ore dressing garden awl (2), sorting space (3), magnet exciting coil (4) magnetic conduction garden awl (5), concentrate bucket (6), motor and decelerator (7), frame (8), mine tailing bucket (9).
Garden awl magnetic separator drives inversion ore dressing garden awl (2) by motor and decelerator (7) and slowly moves.Direct current by certain voltage in magnet exciting coil (4), coil produces the required magnetic field intensity of magnetic separator work, its magnetic line of force radially passes sorting space (3),---magnetic conduction garden, another sorting space---another iron-core coil---awl (5) constitutes closed magnetic circuit (seeing accompanying drawing 3) through hollow ore dressing garden awl (2).The quantity of magnet exciting coil is consistent with the quantity in sorting space.Hollow ore dressing garden awl (2), iron-core coil in the magnetic circuit, magnetic conduction garden awl (5) are made by the engineering pure iron.
The design feature of garden awl magnetic separator is: sorting space and ground are evenly distributed in around the poppet surface of hollow ore dressing garden at an angle, and quantity can two, four, six, eight.The magnetic line of force radially passes the sorting space, is inverted hollow ore dressing garden awl itself and plays sorting.And the magnetic line of force of the 20th kind of magnetic system is to pass the sorting space vertically in the annex 1, and rotation garden awl dish itself only plays a part feeding.This is one of main distinction of the utility model and prior art.
When garden awl magnetic separator ore dressing is worked, omitted the feeding belt of disc type or roll-type magnetic separator, material freely glides from the fixing top on iron yoke inclined-plane or with the feeding of electromagnetic exciting plate, thereby the air-gap thickness in sorting space very little (I reaches 2 millimeters), therefore the magnetic field intensity of the hollow ore dressing garden awl flank of tooth reaches as high as 1512000A/m, can the sorting weak magnetic substance such as zircon etc.
Hollow ore dressing garden awl is that magnetic is the part of magnetic circuit.In order to make the magnetic line of force pass the purpose of magnetic resistance such as reaching when bore in the garden, the wall thickness in the cross section of hollow ore dressing garden awl changes, and big end wall is thick big, and the small end wall thickness is little, and the magnetic line of force will pass through awl cross section, hollow garden up and down equably.Like this, hollow ore dressing garden awl all can play sorting up and down.
Entered in the sorting space (3) by hopper gate by feed bin (1) by sorting material.The air-gap thickness in sorting space is that top is big, and the bottom is little.Therefore, the magnetic field intensity in sorting space, top is less, can sorting magnetic the material of strong (being that relative magnetic susceptibility is bigger), bottom sorting space magnetic field intensity is bigger, can sorting magnetic the material of weak (being that relative magnetic susceptibility is less).This shows, by sorting material by the sorting space, more ferromagnetic material is under magneticaction, inhaled on the upper face of hollow ore dressing garden awl, when remaining is moved to the bottom in sorting space by sorting material, wherein weak magnetic substance is inhaled on the lower surface of hollow ore dressing garden awl under the effect of bigger magnetic force.When hollow ore dressing garden awl is being with them to turn to material discharge region lentamente, they are discharged in the different concentrate buckets.Mine tailing then drops in the mine tailing bucket along the static inclined-plane in sorting space.
In producing use, need to regulate sorting space empty air gap thickness sometimes.For example, for the variation that adapts to feeding granularity and sort different magnetic minerals, need to change the sorting space magnetic field intensity (except that the size that changes exciting current), all to change the air-gap thickness in sorting space, at this moment just can as long as hollow ore dressing garden bored to move up and down slightly.
There are two kinds of forms in the magnetic system of garden awl magnetic separator, and hollow ore dressing garden awl can inverted or just be put.Accompanying drawing 4 is exactly the structural representation of another kind of garden awl magnetic separator.(1) be feed bin, (2) for hollow ore dressing garden awl, (3) be frame for magnetic conduction garden awl, (7) for motor and decelerator, (8) for magnet exciting coil, (5) for sorting space, (4).Be characterized in that hollow ore dressing garden awl just puts.Around material was flowed to by static top of just putting magnetic conduction garden awl, middle part, the outside was a hollow ore dressing garden awl of just putting rotation.The garden awl magnetic separator of two kinds of different magnetic systems has identical performance and effect.
The utility model has been compared following advantage and effect with disc type, roll-type magnetic separator:
(1) upper air crack in sorting space is big, and magnetic field intensity is less relatively, can choose than ferromagnetic substance; Air-gap little magnetic field intensity in bottom is relatively large, can choose weak magnetic substance, thereby obtains multiple sorting product.
(2) leakage field of magnetic system seldom, the magnetic flux utilization rate is higher, can reach more than 50%, so energy consumption is low.
(3) many sortings job space is compared with other magnetic separators that weigh with machine, and productivity ratio improves greatly.
(4) simple and compact for structure, machine is heavy lighter, low cost of manufacture, and the productivity ratio that the unit machine is heavy is also higher.
(5) installation is easy to adjust.
