Description
[affiliated technical field]
The present invention relates to a kind of device for thinning of mineral matter slurry, especially a kind ofly be provided with flow guiding disc, have adjustable valve body, the suitable and supporting device of complete equipment for processing mineral matter slurry on it.
[background technology]
The large-scale production of mineral chylema (as water-coal-slurry) up to now, adopts the wet ball-milling technology of ball vibrating head grinding machine to carry out mostly.Traditional technology is to utilize jaw crusher raw ore (as coal) or ore concentrate (as coal) to be crushed to the particle of 20-30 millimeter, iron block in tramp iron separator removal ore deposit (as coal), be crushed to the following particle of 3-5 millimeter through hammer mill again, add entry and additive in proportion and form the mineral matter centrotheca, go forward side by side into ball mill, in ball mill, obtain mineral chylema (as water-coal-slurry) magma under the ball action of steel ball, magma adds stabilizing agent after filtering and carries out the brute force stirring, finally obtains finished product mineral chylema (as water-coal-slurry).
Traditional ball milling mineral chylema (as water-coal-slurry) crushing technology exists power consumption big, mainly is that in-fighting is big; Simultaneously, to the particle size after cracking poor controllability in the mineral chylema (as water-coal-slurry), the steel ball waste is big; In addition, single unit system is bulky.
[summary of the invention]
The objective of the invention is to change the structure and the crumbling method of existing ball mill, a kind of device for thinning that has the mineral matter slurry of valve body on flow guiding disc and the flow guiding disc that is provided with is provided, by regulating the spacing of the corresponding valve body that is provided with, can effectively control the particle size after cracking of mineral matter, high efficiency, energy efficient, and compact conformation, volume are little.
The present invention solves the technical scheme that the prior art problem adopted: a kind of device for thinning of mineral matter slurry, the housing that comprises band charging aperture and discharging opening, it is characterized in that being provided with at least in the housing two flow guiding discs, the edge of described flow guiding disc is cambered surface, the cambered surface top has the valve body of high-wearing feature, and the outer surface of valve body forms the friction striking face; The surface of flow guiding disc of She Zhiing and valve body thereof forms the jet chamber of mineral matter slurry in opposite directions; Have through hole at least one flow guiding disc and the valve body thereof, through hole forms the slurry passage; The zone that the slurry passage is communicated with the jet chamber forms impact cavity.Raw ore (as coal) or ore concentrate (as coal) enter housing through the centrotheca that forms after the preliminary working from charging aperture, in the drainage in jet chamber with converge under the effect, flow into impact cavity at a high speed with mode of jet, the mineral matter that arrives in this regional centrotheca is clashed into mutually, these mineral matters simultaneously with valve body on the friction striking face (body wall in impact cavity zone is mainly rubbing surface, the body wall at slurry passage place is mainly striking face, usually also be striking face in corner that rubbing surface is connected with striking face) sidewall collision (striking face on the main and valve body clashes into), thereby make particle realize broken and refinement, discharge from discharging opening by the slurry passage at last.The edge camber of flow guiding disc extends out face, and this shape plays effective guide functions.In addition, charging aperture here and discharging opening can exchange, and promptly the mineral matter centrotheca can enter in the housing from charging aperture, outside discharging opening is discharged housing; Also can enter in the housing, outside charging aperture is discharged housing from the mouth that comes out.The charging aperture of mentioning below, discharging opening, feed end and discharge end also can exchange.
As the further of technique scheme improved and replenish, the present invention adopts following technical measures: the shape in described jet chamber is the little reducing shape of outer imperial palace.Outer end, jet chamber diameter dimension is 20-200mm, and inner diameter dimension is 10-100mm, and the impact cavity diameter dimension is 0.001-20mm.Help converging slurry, increase pressure and form jet and inject impact cavity, produce effectively bump.
Valve body on the described flow guiding disc and flow guiding disc main body are for dividing body structure, and the friction striking face of valve body can be zigzag structure or helical structure.This can make flow guiding disc and valve body adopt unlike material, and comparatively cheap material is adopted at the position that does not contact with mineral matter, avoids the whole defective that adopts the high rigidity material to cause cost to rise of flow guiding disc.In addition, divide body structure to also help in time, be convenient for changing the valve body of wearing and tearing.The irregularly shaped of friction striking face helps further fragmentation of material.
Described flow guiding disc is two, and the valve body on flow guiding disc is connected with driving mechanism, and another valve body is fixed on the flow guiding disc.The translation of movable valve body energy makes two valve body relative distances adjustable, with the spacing between the regulation valve body, thus the volume of change impact cavity.Driving mechanism wherein is stepper motor band reductor controlling organization or adds spring controling mechanism or add the accumulator controlling organization or add accumulator controlling organization or jointly controlling mechanism or being variable-frequency motor band reductor controlling organization for mechanical, electrical, liquid, gas for the hydraulic circuit controlling organization or for hydraulic circuit for the pneumatic circuit controlling organization or for pneumatic circuit for servomotor band reductor controlling organization or for mechanical mechanism.
One of flow guiding disc of She Zhiing and valve body thereof are discoid in opposite directions, and one is circular.
The through hole of described valve body can be one or a plurality of.
Described driving mechanism is handled by automatic control system, and the press detection sensor of described control system is arranged on the charging aperture place.Press detection sensor detects the pressure of charging aperture, and pressure signal is reacted to the spacing of automatic control system with regulation valve body, to guarantee the constant pressure of impact cavity mesohigh slurry.
Described valve body is that pottery or diamond or tungsten carbide or hardness are greater than HRC60 hard material.Have sufficiently high hardness,, simultaneously, prevent that valve body from crossing quick-wearing, avoid frequent replacing to reach the particle requirement.
The invention has the beneficial effects as follows: 1, flow guiding disc can guide the path that mineral matter slurry enters, and the valve body which is provided with not only can change the volume of impact cavity but also material particle space can be provided.Regulate spacing between the corresponding valve body by driving mechanism, can change the jet pressure that enters cavity, effectively control particle size after cracking.2, technical scheme high efficiency of the present invention is avoided in-fighting, and effective use of energy sources cuts down the consumption of energy.3, this apparatus structure compactness, volume are little, and floor space is little, conveniently produce, processing, transportation.
