Abstract
The utility model provides a rotary-type tailing separator. The rotary-type tailing separator comprises a separator cylinder body (1), an inlet tube (8) and a powder return tube (7) which are arranged at the lower end of the separator cylinder body and are communicated with the separator cylinder body, wherein an outlet tube (10) which is communicated with the separator cylinder body is arranged at the upper end of the separator cylinder body (1), the separator cylinder body (1) is internally provided with an inner cylinder body (4) and impeller rotors (2) which is provided with dynamic blades (3), a driving motor (9) which drives the impeller rotors (2) to rotate is arranged at the upper end of the separator cylinder body (1), axial baffle plates with adjustable angles are uniformly distributed at the lower end of the dynamic blades (3) along a circumferential direction, and at least the dynamic blades (3) are partially provided with extension parts.
Description
Technical field
The utility model relates to a kind of mill separator, particularly a kind of rotating classifier.
Background technology
The critical piece of traditional rotary separator is the rotor that a plurality of blades are housed, and motor drives rotor rotation through transmission mechanism.When the wind powder mixture from coal pulverizer passes through rotor region, under the drive of rotor, rotate, thicker coal dust is separated under the effect of centrifugal force and blade bump, and all the other qualified coal dusts are taken out of with air-flow.
Sound leaf mating type rotary separator is before rotary separator, to add the combination of stator blade separator to form.Form a ring-like centrifugal separating area between stator blade and the rotor; Band powder air-flow at first carries out pre-separation in the stator blade Disengagement zone; Isolate thicker coal dust particle; Wind powder mixture separates in centrifugal separating area once more, and isolated rough coal powder is all bored in the coal pulverizer that falls back through time powder and continued to mill, and qualified coal dust is carried out separator by air-flow.
But traditional sound leaf mating type rotary separator still exists the more problem of coal dust corase particles content.
The utility model content
The utility model technical problem to be solved provides a kind of rotating classifier.
For solving the problems of the technologies described above, the utility model is realized as follows:
A kind of rotating classifier; The inlet tube (8) and the powder retrieving pipe (7) that comprise separator cylindrical shell (1) and be arranged on separator cylindrical shell lower end and be connected with the separator cylindrical shell; The upper end of separator cylindrical shell (1) is provided with the outlet (10) that is connected with the separator cylindrical shell; Be provided with inner barrel (4) in the described separator cylindrical shell (1) and have the vane rotor of dynamic blade (3); Separator cylindrical shell (1) upper end is provided with the driving motor (9) that drives impeller rotor (2) rotates, and is evenly equipped with the axial baffle of adjustable angle by circumferencial direction in the lower end of dynamic blade (3), and the said dynamic blade of at least a portion (3) is provided with extension.
The good effect of the utility model is:
The utility model is owing to have extension, makes that powdered granule can bump and the refinement particle with extension on the one hand in the air-flow, also can avoid increasing the flowability of air-flow on the other hand, further the refinement particle.Further, on a part of dynamic blade, extension is set, can blows into the air-flow that contains particle and influence inlet tube 8 so that the air-flow that extension produces can be not excessive.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the tangent plane structural representation of the utility model embodiment 1.
Fig. 3 is the structural representation of the utility model embodiment 2.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Referring to Fig. 2, in a plurality of dynamic blades 3, at least a portion dynamic blade 3 has extension.Extension can be consistent with dynamic blade 3 width, also can be littler than the width of dynamic blade 3.
Embodiment 2, and referring to Fig. 3, the inner barrel 4 of present embodiment is an opened upper end, and lower disposed has the cavity of air-lock device 11, and other annexation is with embodiment 1.An isolated coarse granule part gets into powder retrieving pipe 7 along the landing of separator cylindrical shell inwall, and another part falls in the inner barrel, behind air-lock device, gets into powder retrieving pipe 7.
The utility model is owing to have extension, makes that powdered granule can bump and the refinement particle with extension on the one hand in the air-flow, also can avoid increasing the flowability of air-flow on the other hand, further the refinement particle.Further, on a part of dynamic blade, extension is set, can blows into the air-flow that contains particle and influence inlet tube 8 so that the air-flow that extension produces can be not excessive.
In addition, the utility model axial baffle and movable blade combined type rotating classifier, fineness of pulverized coal can be adjusted with changeing in rotating speed through the axial baffle aperture simultaneously.With leave.Dynamic formula, twin shaft compare to baffle separator, and axial baffle and movable blade combined type rotating classifier has advantages such as fineness of pulverized coal is easy to adjust, the fineness of pulverized coal adjustable range big, dust separator outlet coal fine good uniformity.
The coal dust coarse granule reduces, and ash content carbon obviously descends, and improves the efficiency of combustion of boiler; Separative efficiency is high, can improve exerting oneself and reducing advantage such as pulverized coal preparation system power consumption of pulverized coal preparation system.Compare with traditional rotary separator, have better separating effect, and security of system is reliable, regulating measure is many, can effectively guarantee advantages such as coal pulverizer running time.
Claims (4)
