Description of drawings
Below in conjunction with accompanying drawing and instance the utility model is further described.
Fig. 1 is the structure principle chart of the utility model.
The specific embodiment
The use flow process of the utility model can ascribe the slag treatment technology of the following stated to, and it may further comprise the steps:
C), slag is carried out the gravity screening, from wherein isolating non-ferrous metal, heavy metal and obtaining the finished product slag.
Further, before step c), also may further comprise the steps successively as preferred embodiment:
A), broken slag to even fine particulate, obtain slag granules;
B), said slag granules is carried out deironing, the irony in the slag granules is separated; Also have, the slag described in the step c) is the slag granules of handling through step b); After step c), also comprise the step of the finished product slag being processed cement calcine-free brick and other cement calcine-free prefabricated components.
Further as preferred embodiment, the shattering process in the said step a) is twice, be respectively formerly the power that slag is carried out broken and after smart broken.
Further as preferred embodiment, the iron removal in the said step b) is twice, be respectively formerly thick deironing and after smart deironing.
Further as preferred embodiment, the gravity screening process in the said step c) is twice, be respectively formerly screening go out the bulky grain metallics coarse fraction and after screening go out the fine screen branch of granule metallics.
The structure of brief description the utility model, with reference to Fig. 1, the slag treatment device, it comprises having the gravity screening module 3 that can sieve out non-ferrous metal in the slag, heavy metal function.
Further as preferred embodiment, before said gravity screening module 3, also comprise the broken module 1 and deironing module 2 that connect in order, said deironing module 2 connects with gravity screening module 3; Back in gravity screening module 3 also is connected with brickmaking module 4.
Further as preferred embodiment; Said broken module 1 comprises jaw crusher and the hammer mill that all has charging aperture and discharging opening; Between the discharging opening of jaw crusher and the charging aperture of hammer mill; Be provided with the delivery track that they are coupled together,, also be provided with the delivery track that itself and deironing module 2 are coupled together at the discharging opening place of hammer mill.
Particularly, said jaw crusher be a kind of utilize two jaws to the extruding of material and flecition come coarse crushing or in the crushing mechanism of broken various hardness materials.Its crushing mechanism is made up of fixed jaw and swing jaw, when two jaws near the time material be broken, the material piece less than discharging opening when two jaws leave is discharged by the bottom.Its crushing action is intermittently to carry out.This disintegrating machine is simple in structure because of having, reliable operation and can broken hard material etc. advantage be widely used in industrial departments such as ore dressing, construction material, silicate and pottery.Because mostly the raw slag at initial stage is harder big bulk, therefore preferred jaw crusher is as the power crushing mechanism that begins most.
Hammer mill is a kind of high speed impact effect that utilizes tup, the crushing mechanism of broken and operation in small, broken bits during material is carried out.Tup is articulated on the high speed rotor rotated, and underpart is provided with grid section with the control marker size.The material of sending into disintegrating machine at first receives impact and the primary crushing of the tup of high-speed motion, and obtains kinetic energy simultaneously, flies to the crushing shell on the casing inner wall at a high speed and receives fragmentation once more.Material less than the grid section slit is discharged from outside the machine, on grid section, receives the impact and the grinding of tup once more greater than the material piece in grid section slit, after less than the grid section slit, is discharged from.The ratio of reduction is big because hammer mill has, marker size even, cross few, the low power consumption and other advantages of crushed material, so at the machinery of this preferred its conduct to the smart fragmentation of slag.
Further as preferred embodiment; Said deironing module 2 comprises self-tipping type magnetic separator de-ironing and strong magnetic self-unloading tramp iron separator; The discharging opening place of said self-tipping type magnetic separator de-ironing is furnished with sieves the delivery track that module 3 couples together with itself and gravity, and said strong magnetic self-unloading tramp iron separator is located on this delivery track.
Particularly; Said self-tipping type magnetic separator de-ironing is a kind of deironing machinery that is made up of several parts such as high-performance magnetic core, steel construction, reducing motor, cylinder, belts, itself has delivery track, when granular material through the self-tipping type magnetic separator de-ironing under the time; The bulk ferromagnetism impurity that is mingled in the material is picked up; Because the running that the belt on the tramp iron separator does not stop when the no magnetic region of the superincumbent ferromagnetic materials process of absorption, is just scraped by the part of scraping on the belt; Fall to collection iron case, thereby reach the purpose of continuous automatic iron removing.Because it can remove the bulk ironware, therefore preferred its machinery as thick deironing.And strong magnetic self-unloading tramp iron separator principle and self-tipping type magnetic separator de-ironing are similar, can trickle iron filings be reacted, and further remove remaining scrap iron material.
Further as preferred embodiment; Said gravity screening module 3 comprises jigging machine and the shaking table that all has charging aperture and discharging opening; Between the discharging opening of said jigging machine and the charging aperture of shaking table; Be provided with the delivery track that they are coupled together,, also be provided with the delivery track that itself and brickmaking module 4 are coupled together at the discharging opening place of shaking table.Particularly, preferred wet type jigging machine and vibrations shaking table are as said jigging machine and shaking table.
Jigging machine is a kind of gravity beneficiation equipment, utilizes water as the ore dressing medium, carries out sorting according to the difference in specific gravity of mineral and barren rock; Have energy-conservation, efficient, the ore dressing advantage of environmental protection; Especially the sorting for the coarsegrain mineral has effect preferably, also is that other preparation equipments can't be substituted.And, use the wet type jigging machine of using in the mining industry here as the gravity sieving machine of handling slag in the utility model, can make full use of its characteristics, as the large-scale metallics screening installation after pouring water.
Because jigging machine is not too responsive to trickle material, so gravity screening module 3 also is provided with shaking table.Shaking table has the bed surface that waves, tilt, and cooperates the flushing water-bath, can analyse apace and tell metal particle, guarantees that last treated slag contains non-ferrous metal and the heavy metal amount is minimum.Certainly, all above-mentioned separators comprise scrap iron and other metals, can recycle through recovering mechanism is set.
For gravity screening module 3, except above-mentioned embodiment, can also adopt the equipment of electromagnetic separation heavy metal.This equipment be that the principle of utilizing conductor in high-frequency alternating magnetic field, can produce vortex flow designs.Produce repulsive force between induced field that vortex flow produces and the equipment magnetic field, make conductor leap separation automatically.
More than be that preferred embodiments to the utility model specifies; But the invention is not limited to said embodiment; Those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
