Abstract
The invention discloses a kind of coal power separator, including shell body, fine powder passage is provided with the top of the shell body and bottom is provided with feeding mouth, split tunnel is provided with the feeding mouth, some cross bars are provided with the split tunnel, the surface of the cross bar is provided with teeth, and the bottom of the inner housing is provided with coarse powder passage, the coarse powder vias inner walls bottom is provided between stripper, stripper and the coarse powder passage and is provided with small-sized vibrator.By setting split tunnel, cross bar and teeth, wind enters fashionable with coal dust from feeding mouth, and adsorb fine grain larger pulverized coal particle timely can be broken up by the teeth on cross bar, so that entering screening area after raw material sufficiently separation, screening effect more preferably, improves production efficiency, reduces production cost.
Description
Technical field
The present invention relates to powder concentrator field, more particularly to a kind of coal power separator.
Background technology
Coal power separator work flow is that the air that coal mill comes enters powder concentrator with material by bottom airduct, through inner cone
Slow down after rectification along the passage between shell body and inner housing and rise, coarse powder therein slips into coarse powder through gravitational settling along Outer Taper
Rewinding cylinder realizes that the air after gravity separation, gravity separation is enclosed under effect with material particles in the rotation of water conservancy diversion and rotor, is leading
Stable horizontal vortex powder-separating area is formed between fan blade and rotor.The dust granules moved in vortex will be simultaneously by gravity, wind-force
With the effect of rotary centrifugal force, tiny slight particle is inhaled into internal rotor with air-flow and flows through discharge pipe into dust-precipitator below
Effect finished product fine powder is separated.Coarse particles then fall, and coarse powder rewinding cylinder is pooled to through inner cone, return to grinding machine and regrind.
Existing coal power separator is in operation, and the fine powder of some very littles is easily adhered on some larger pulverized coal particle surfaces
Particle, in the presence of cage-type rotor still the little particle for being attached to large particle surface can not remove, cause its doping larger
The coal dust of particle returns to grinding machine and regrinded simultaneously, and low production efficiency adds production cost.
Therefore, a kind of coal power separator is invented necessary to solve the above problems.
The content of the invention
It is an object of the invention to provide a kind of coal power separator, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of coal power separator, including shell body, it is described
Inner housing is provided with shell body, the shell body is socketed with rotating shaft, and the rotating shaft bottom is arranged on inside inner housing and top
The outside of shell body is arranged on, the rotating shaft bottom is connected with cage-type rotor, and the both sides of the cage-type rotor are provided with
Wind blade, the wind blade is arranged between shell body and inner housing, be provided with the top of the shell body fine powder passage with
And bottom is provided with feeding mouth, the feeding mouth and is provided with split tunnel, and some cross bars, institute are provided with the split tunnel
The surface for stating cross bar is provided with teeth, and the bottom of the inner housing is provided with coarse powder passage, and the coarse powder vias inner walls bottom is set
It is equipped between stripper, stripper and the coarse powder passage and is provided with small-sized vibrator.
It is preferred that, the rotating shaft transmission is connected with motor.
It is preferred that, the commercially available JZK-5 vibrators of model of the small-sized vibrator.
The technique effect and advantage of the present invention：By setting split tunnel, cross bar and teeth, wind is with coal dust from feeding mouth
Enter fashionable, adsorb fine grain larger pulverized coal particle timely can be broken up by the teeth on cross bar so that raw material is sufficiently separated
Enter screening area afterwards, screening effect more preferably, improves production efficiency, reduces production cost.
Brief description of the drawings
Fig. 1 is front view of the present invention；
Fig. 2 is split tunnel top view of the present invention.
In figure：1 shell body, 2 inner housings, 3 rotating shafts, 4 cage-type rotors, 5 wind blades, 6 feeding mouths, 7 split tunnels, 8 horizontal strokes
Bar, 801 teeth, 9 fine powder passages, 10 coarse powder passages, 11 strippers, 12 small-sized vibrators.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The invention provides a kind of coal power separator as shown in Figure 1-2, including shell body 1, it is provided with the shell body 1
Inner housing 2, the shell body 1 is socketed with rotating shaft 3, and the bottom of rotating shaft 3 is arranged on the inside of inner housing 2 and top is set outside
The outside of housing 1, the bottom of rotating shaft 3 is connected with cage-type rotor 4, and the both sides of the cage-type rotor 4 are provided with wind-guiding
Blade 5, the wind blade 5 is arranged between shell body 1 and inner housing 2, and the top of shell body 1 is provided with fine powder passage 9
And bottom is provided with feeding mouth 6, the feeding mouth 6 and is provided with split tunnel 7, is provided with the split tunnel 7 some
Cross bar 8, the surface of the cross bar 8 is provided with teeth 801, and the bottom of the inner housing 2 is provided with coarse powder passage 10, the coarse powder
The inwall bottom of passage 10 is provided with stripper 11, and small-sized vibrator 12 is provided between the stripper 11 and coarse powder passage 10,
By setting split tunnel 7, cross bar 8 and teeth 801, wind enters fashionable with coal dust from feeding mouth 6, adsorbs fine grain larger coal
Powder particles timely can be broken up by the teeth 801 on cross bar 8 so that enter screening area, screening effect after raw material sufficiently separation
