Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to Limit the present invention.
As shown in Figure 1 to Figure 3, the present invention provides a kind of sides to enter the wind Verticle vortex powder concentrator, the whirlpool including being located at top Shell 1 and the conical shell 2 for being located at lower part;The volute 1 is horizontally disposed, and the open end of the volute 1 is air inlet 1-1;In the whirlpool 1 top of shell is equipped with the air outlet 1-2 of connection dust arrester installation;Cage rotor 3 is equipped in volute 1, the air outlet 1-2 is located at cage type The top of 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 patent of invention is related to is not intended to specific standard, specific material and specific use environment, so that Finished product require it is also and nonspecific, therefore can air quantity, 3 revolving speed of cage rotor, different zones wind guide vane by adjusting powder concentrator Suitable production status is arranged in the deflection angle of piece 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 present invention, material brings top volute 1 by air-flow, realizes the first time eddy flow centrifugal classification and second of volute 1 Secondary 3 centrifugal classification of cage rotor;The excessive material of most of partial size is pre-separated in first time assorting room, reduces second The workload of secondary sorting improves the whole efficiency of separation;Furthermore whole being brought by air quantity by powder concentrator of material, powder concentrator Device external does not need material lift equipment, itself does not need spout and spreading disc mechanism yet, structurally reasonable, reliable for operation, Abrasion is reduced, energy consumption is reduced;The on-demand powder air quantity of material is entered by 1 side of volute, reduces powder concentrator internal gas flow improving material Height, to reduce the internal drag of powder concentrator, while the technology arrangement height of powder concentrator equipment can also be reduced, save it is whole The construction investment of body project.
Side air inlet Verticle vortex powder concentrator of the invention can be used for cement roller press final grinding system, it can also be used to raw material The occasion of final grinding system of roll squeezer and the sorting of the materials such as various slags or steel slag and other metallurgical slag final grinding system of roll squeezer, The roll squeezer end grinding field that can be applied to metal or nonmetallic ore, can greatly improve grinding efficiency.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
