Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain that this is practical
It is novel, it is not used to limit the utility model.
As shown in Figure 1 to Figure 3, the utility model provides a kind of side air inlet Verticle vortex powder concentrator, including is located at top
Volute 1 and be located at the conical shell 2 of lower part；The volute 1 is horizontally disposed, and the open end of the volute 1 is air inlet 1-1；Institute
State the air outlet 1-2 that 1 top of volute is equipped with connection dust arrester installation；Cage rotor 3 is equipped in volute 1, the air outlet 1-2 is located at
The top of cage rotor 3；
Support device 4 is equipped with above volute 1；The support device 4 is equipped with the driving device of driving powder concentrator work
5；The driving device 5 is connect by slewing equipment with the cage rotor 3；
Wind blade 6 is circumferentially uniformly provided in the outside of the cage rotor 3；Meet separation condition outside cage rotor 3
Material can enter the powder-separating area domain of cage rotor 3 by the gap of wind blade 6.
The shelly-shaped hypocentrum 7 of circular cone is equipped in the conical shell 2, the hypocentrum 7 is placed in the underface of cage rotor 3,
The lower end of hypocentrum 7 is communicated with middle coarse powder discharge pipe 7-1；The end of the middle coarse powder discharge pipe 7-1 extends substantially downward to described
The outside of conical shell 2；
Coarse powder discharge pipe 2-1 is communicated in the lower end of the conical shell 2；
Due to the high speed rotation of cage rotor 3, the airflow field for attracting material will form in 3 near zone of cage rotor, this
Sample is largely focused on material around cage rotor 3, and the material near 1 inner wall of volute is less, and this material is unevenly distributed
It will cause after small particles material is swept along by large granular materials and be not easily accessible cage rotor 3, to influence separating effect；Therefore it is
Avoid such case, it is preferred that 1 bottom of volute along air-flow trend be provided with the partition 1-3, the partition 1-3 of setting from
Air inlet 1-1 is extended at about the 1/2 of 1 stroke of volute, and according to realization operating condition needs, the material of air-flow and carrying can be from partition 1-
3 two sides enter volute 1, so as to avoid aggregation of the material around cage rotor 3.
Since the equipment that utility model patent is related to is not intended to specific standard, specific material and specific use environment,
So that finished product requirement is also and nonspecific, therefore can be led by adjusting the air quantity, 3 revolving speed of cage rotor, different zones of powder concentrator
Suitable production status is arranged in the deflection angle of air blade 6, to realize the efficient low-consume for entirely selecting powder process.
Theoretically, the revolving speed of cage rotor 3 is higher, and air drag is bigger, and the particle selected is thinner, therefore cage rotor 3
Revolving speed can be according to the requirement of finished particle gradation, fineness and Bi Biao come selection；Each cage rotor 3 is by driving device 5
It is driven by slewing equipment, driving device 5 includes motor, and revolving speed adjustment is realized by the frequency control of motor.
The spacing of the wind blade 6 is smaller, the angle between 3 radial direction of wind blade 6 and cage rotor is bigger, then material
Fineness it is thinner, higher than table, but corresponding resistance (air drag, particle and shock of wind blade 6 etc.) can also increase, because
This needs is adjusted according to spacing and angle of the material requirement to wind blade 6.Preferably, the spacing of the wind blade 6
In 20~100mm；The angle of wind blade 6 and cage rotor 3 is 15~75 °.
Above-mentioned side air inlet Verticle vortex powder concentrator selects powder method, includes the following steps:
S1, material bring powder concentrator by air-flow from air inlet 1-1, under the action of air intake passage internal partition 1-3, air-flow and
It carries material and is divided into two parts and enter in the volute 1 along air inlet 1-1；
Part bulky grain in S2, material is fallen first in the case where gravity, vortex centrifugal power and gas carry power compound action
In to the conical shell 2；Another part bulky grain is stopped by wind blade 6, not can enter cage rotor 3, also falls into the cone of lower section
In shell 2, then two parts bulky grain passes through coarse powder discharge pipe 2-1 together and is discharged powder concentrator；
S3, small particles material follow air-flow pass through wind blade 6 and enter cage rotor 3 powder-separating area domain；In gas
Stream high speed rotation cage rotor 3 by material fine grained and middle coarse granule separate, wherein be greater than partition size object
Material falls into hypocentrum 7 and slides to middle coarse powder discharge pipe 7-1, ultimately forms middle coarse powder and is discharged to outside powder concentrator；
S4, cage rotor 3 is passed through in rotation less than the material of partition size, and entered with air-flow by air outlet 1-2
The subsequent dust arrester installation of powder concentrator, is finally collected as finished product.
In the utility model, material brings top volute 1 by air-flow, realize volute 1 first time eddy flow centrifugal classification and
Second of 3 centrifugal classification of cage rotor；The excessive material of most of partial size is pre-separated in first time assorting room, is reduced
The workload of second of sorting, improves the whole efficiency of separation；Furthermore whole being brought by air quantity by powder concentrator of material, choosing
Material lift equipment is not needed outside powder machine equipment, itself does not need spout and spreading disc mechanism, structurally reasonable, operation can yet
It leans on, reduces abrasion, reduce energy consumption；The on-demand powder air quantity of material is entered by 1 side of volute, is reduced powder concentrator internal gas flow and is promoted object
The height of material to reduce the internal drag of powder concentrator, while can also reduce the technology arrangement height of powder concentrator equipment, save
The construction investment of whole project.
The side air inlet Verticle vortex powder concentrator of the utility model can be used for cement roller press final grinding system, it is also possible to
It is sorted in raw material final grinding system of roll squeezer and the materials such as various slags or steel slag and other metallurgical slag final grinding system of roll squeezer
Occasion, can be applied to the roll squeezer end grinding field of metal or nonmetallic ore, grinding efficiency can be greatly improved.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
