Abstract
The utility model discloses a high efficiency centrifugal selective separation machine, comprising an air inlet, a coarse powder outlet and an exhaust outlet. The air inlet and the coarse powder outlet are arranged at the lower part of the casing, and the exhaust outlet is arranged at the upper part of the casing. The inner part of the casing is provided with a rotating blade wheel, and a cone is connected on the rotating blade wheel. One end of a bearing box is fixed on the casing, and the other end is connected with the rotating axle of the rotating blade wheel. A drive device is provided on the casing, and the drive device is connected with the rotating axle of the bearing box. The drive device adopts the frequency conversion motor, and the inner part of the bearing box is filled with compressed air. The utility model has the advantages of high efficiency of powder selection and long service life, and the granularity of the powder selecting can be adjusted.
Description
Technical field:
The utility model relates to a kind of efficient centrifugal formula powder concentrator.
Background technology:
At present, not only overall dimensions are big for the through type mill separator of domestic production, and weight of equipment is big, and its grinding efficiency is low, select the powder degree not transfer, and service life is short.
Summary of the invention:
The purpose of this utility model is: a kind of grinding efficiency height is provided, selects that the powder degree can be transferred, the efficient centrifugal formula sorting machine of long service life, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises air inlet (2) and the oversize outlet (3) that is located at housing (1) bottom, and the exhaust outlet (4) that is located at housing (1) top, in the inside of housing (1) rotary blade (5) is housed, on rotary blade (5), be connected with cone (6), one end of bearing housing (7) is fixed on the housing (1), the other end links to each other with the rotating shaft of rotary blade (5), drive unit (8) is housed on housing (1), drive unit (8) links to each other with the turning cylinder of bearing housing (7), and drive unit (8) adopts adjustable frequency motor; In bearing housing (7), be connected with compressed air.
The utility model compared with prior art because rotary blade drives rotation with adjustable frequency motor, the external diameter linear velocity of rotary blade can reach 12.7-10.7m/s, makes its grinding efficiency height; By its rotating speed of frequency shift of adjusting adjustable frequency motor, can make the rotating speed adjustable (120-24r/min) of the rotary blade that is subjected to the adjustable frequency motor driving simultaneously, thereby the granularity of selecting powder can be regulated according to producing needs; In bearing housing, feed compressed air and then make dust can not enter bearing housing, prolonged the life-span of rolling bearing, correspondingly make obtain prolonging the service life of sorting machine.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: as shown in Figure 1, an air inlet (2) and an oversize outlet (3) are set in the bottom of housing (1), on the top of housing (1) exhaust outlet (4) is set, bearing is loaded onto in bottom at housing (1), on bearing, establish 8 bolts hole, fixing with bolt and basis; Adorn a rotary blade (5) in the inside of housing (1), rotary blade (5) is made up of 30 blades, the dimensional tolerance of blade is h11, the quality homogeneous, 30 blades evenly distribute by circumference, do static balancing test with rotary blade (5) welding and integral body, rotary blade (5) is contained on the rotating shaft, and fix with cover type nut, below rotary blade (5), connect a cone (6) with bolt, one end of bearing housing (7) is fixed on the housing (1), the other end links to each other with the rotating shaft of rotary blade (5), adorn a drive unit (8) at the top of housing (1), and the turning cylinder of drive unit (8) with bearing housing (7) linked to each other, drive unit (8) adopts adjustable frequency motor; The attachment bolt of all rotating parts, 1277 type anaerobism thread locking sealants are smeared at the screw thread place during assembling, in case thread looseness, the material of blade, rotary blade (5) and following cone (6) is 16Mn; Bearing housing (7) is a global facility, upper flange dish and housing (1) are used bolted on connection, be labyrinth sealing below and between the rotary blade (5), bearing housing (7) top is to adorning 2 single row conical bearings, and 1 double-row radial ball bearing is adorned in bearing housing (7) bottom, keeps malleation in the bearing housing (7) in order to make, dust can not be entered, prolonging the life-span of rolling bearing, the logical entrance pressure air that contracts has lubricating arrangement with interpolation lubricating grease on the rolling bearing bearing housing (7) in; The adjustable frequency motor of drive unit (8) directly connects with vertical type speed reducer (change gear), is put on the bearing that is positioned at above the powder concentrator, and uses bolted on connection, and the reductor shaft connects with shaft coupling with power transmission shaft, and the power transmission shaft material is 40Cr.
During work, from the petroleum coke dust-containing air stream that air swept mill comes, enter the air inlet (2) of powder concentrator with the speed of 18-20m/s, the cone (6) of air inlet (2) top makes air-flow to flowing all around, because the interior bulk of housing (1) is big, air velocity descends, crude particle dust begins sedimentation, air-flow continues to rise, crude particle dust is under rotary blade (5) action of centrifugal force, sedimentation rapidly, crude particle dust oversize outlet (3) below powder concentrator flows out and returns air swept ball mill, and fine powder continues to rise with air-flow, enters powder concentrator top, the cloth Dai dust-precipitator that escapes and enter the back through exhaust outlet (4) separates recovery, and the rotating speed of rotary blade (5) is regulated by the adjustable frequency motor on the drive unit (8).
Claims (2)
1. efficient centrifugal formula sorting machine, it comprises air inlet (2) and the oversize outlet (3) that is located at housing (1) bottom, and the exhaust outlet (4) that is located at housing (1) top, it is characterized in that: rotary blade (5) is housed in the inside of housing (1), on rotary blade (5), be connected with cone (6), one end of bearing housing (7) is fixed on the housing (1), the other end links to each other with the rotating shaft of rotary blade (5), drive unit (8) is housed on housing (1), drive unit (8) links to each other with the turning cylinder of bearing housing (7), and drive unit (8) adopts adjustable frequency motor.
2. efficient centrifugal formula sorting machine according to claim 1 is characterized in that: be connected with compressed air in bearing housing (7).
