The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Referring to Fig. 1, the preferred embodiments of the present invention provide a kind of ore pulp grinder, and it comprises base 9, is installed in cylindrical shell 1, pulp cylindrical shell 2, mounting seat 3, reducer pedestal 4, reductor 5 and motor 6 on the base 9.
In other embodiment, cylindrical shell 1 is a single layer structure.
Inner tube installation at cylindrical shell 1 has turning cylinder 8, and even compartment of terrain is provided with the abrasive disk 7 of a plurality of disk types on the turning cylinder 8, and the disc 71 of each abrasive disk 7 is detachable structure or fixing structure, and disc 71 is the structure of adjustable angle.Disc 71 can be multiple shape, as strip, bar-shaped, annular or disc type.A kind of disc 71 of shape can only be installed on the abrasive disk 7, also can be with the disc 71 alternate installations of multiple shape.These structures help stirring and grinding, and can reach good grinding effect.
Please combine referring to Fig. 2, each goes out a pulp inner core 211 is installed in the sizing device 21.Pulp inner core 211 first ends are equipped with pulp sieve plate 2111; Ore pulp in the pulp cylindrical shell 2 is through the grinding of abrasive disk 7, and particle is very little, can flow to out in the sizing device 21 through pulp sieve plate 2111; Impurity is then stayed in the pulp cylindrical shell 2, to realize ore pulp and separate impurities.Preferably, the height of the top of pulp sieve plate 2111 is lower than the height of the top of the highest abrasive disk 7 slightly, so that pulp sieve plate 2111 can be submerged in the ore pulp for a long time.In the time of so just preventing that pulp sieve plate 2111 is exposed in the air, the phenomenon generation that pulp sieve plate 2111 is stopped up in the residual air-dry back of ore pulp on the pulp sieve plate 2111.Second end of pulp inner core 211 is provided with and leaches grout outlet 2112, and preferably, leaching grout outlet 2112 is square structure.In other embodiments, leaching grout outlet 2112 can also be for the structure of other shapes, such as circle.
Lower end at the barrel of pulp inner core 211 also is provided with a piston hole 2113, and piston hole 2113 is used to connect piston 2114.When needs are selected overflow pulp mode for use, only need piston 2114 is extracted, ore pulp flows out from piston hole 2113; When needs were selected the mode that leaches pulp for use, with piston 2114 beyond the Great Wall, ore pulp flowed out from leaching grout outlet 2112.
The upper end that goes out sizing device 21 is provided with peep hole 212, and which kind of pulp mode is the thickness degree that can judge ore pulps through peep hole 212 so that preferentially select for use according to the thickness degree of ore pulp; Concrete, when the particle of ore pulp is thin, select the pulp mode that leaches for use, when the particle of ore pulp is thick, select overflow pulp mode for use.
Be provided with grout outlet 213 in the lower end that goes out sizing device 21, flow out this grinder thereby flow to grout outlet 213 from the ore pulp that leaches grout outlet 2112 and piston hole 2113 outflows.
Preferably, go out sizing device 21 and also comprise end plate 214, end plate 214 bolts are connected out the outside of sizing device 21.When pulp sieve plate 2111 needs to change, only need end plate 214 be removed, pulp sieve plate 2111 is taken out replacing get final product.
See also Fig. 3 to Fig. 5, be equipped with in the upper end of pulp cylindrical shell 2 base plate 3 is installed, it is an annular plectane that base plate 3 is installed, and preferably, the internal diameter end of annular plectane is arranged at intervals with a plurality of breach 31.Preferably, be connected with reducer pedestal 4 in the upper end that base plate 3 is installed, bearing block 41 is installed on the reducer pedestal 4, bearing block 41 has at least an end to be supported on the reducer pedestal 4.Preferably, bearing block 41 adopts the stiff shaft bearing of dual-gripper, so that turning cylinder 8 is more steady at rotation process, the lower end of bearing block 41 is buckled in installs on the base plate 3, and bolt connects.
When base plate 3 is installed with reducer pedestal 4; Earlier lift appointed positions to bearing block 41 and the shafting structure that is installed in the turning cylinder 8 on the bearing block 41 and is installed in abrasive disk 7 compositions on the turning cylinder 8 from the upper end of pulp cylindrical shell 2; Being installed, base plate 3 is installed on the pulp cylindrical shell 2 then; Bearing block in the shafting structure 41 is hung up through the breach 31 that base plate 3 is installed in pulp cylindrical shell 2, shafting structure is rotated to an angle again, the bolt hole that is provided with installation base plate 3 cooperates; Install on the base plate 3 through being bolted to, reducer pedestal 4 is fixed on installs on the base plate 3 at last.
Please refer again to Fig. 1, the top of reducer pedestal 4 is fixed with reductor 5 and motor 6 successively.Reductor 5 connects a turning cylinder 8 through shaft coupling, and turning cylinder 8 extend in the cylindrical shell 1, and turning cylinder 8 can be one or several series connection.
In other embodiment, motor 6 can also directly be connected with turning cylinder 8 through belt pulley.
When using ore pulp grinder of the present invention; Earlier the breeze for preparing being given birth to slurry evenly sends in the cylindrical shell 1 through screw pump from the bottom stock inlet 11 of grinder cylindrical shell 1 continuously; Motor 6 drags turning cylinder 8 through reductor 5, shaft coupling and abrasive disk fully grinds, impacts, shears abrasive media in the cylindrical shell 1 and living slurry, makes powder granule by constantly levigate.
Because constantly carrying, screw pump gives birth to slurry simultaneously; Slurry stream will move from lower to upper; Because the less top that floats over slurry stream of density and from going out after the going out sizing device 21 and the overflow grinder of the present invention of top of cylindrical shell 2 flows into vibratory sieve again, the back of sieving gets into the finished product pond by levigate slurry.Because abrasive disk, abrasive media and slurry cause that because of friction generates heat built-in temperature raises in process of lapping; Therefore in cyclic water jacket, inject the cooling water of certain pressure from grinder cylindrical shell 1 lower water inlet; Take away hot water behind the heat from top delivery port 12 discharge; Make the slurry temperature in the body be lower than 80 ℃, ensure the operate as normal of grinder.
The cylindrical shell 1 employing monomeric form and the draw ratio of ore pulp grinder of the present invention are reasonable, and evenly the abrasive disk 7 of the disk type of setting makes the living slurry of breeze in the present invention, can not backflow, and can not cause overground phenomenon generation; And adopt overflow pulp mode and leaching pulp mode to combine, make pulp more smoothly; The breach 31 that base plate 3 settings are installed in addition makes whole shafting structure directly to hang in from the top, and is easy for installation, quick.
And ore pulp grinder of the present invention relatively maximizes, and is fit to the ultra-fine slurrying of large-scale, big flow; Than traditional grinder, nominal volume of the present invention can reach 10000L, 11000L or more than the 15000L; Accordingly, single-machine capacity of the present invention can reach 560kW, 630kW or 1120kW and more than, and its single machine yield will reach 15m
3/ h～20m
3More than/the h.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
