One side of the main shaft bearing belt pull is provided with a belt pull compensation device, radial support force is provided and the utility model also has vibration damping and isolation actions at the same time.
Description
Technical field
The utility model belongs to the separation machinery technical field, is specifically related to a kind of suspention rotary drum disk centrifuge.
Background technology
Disk centrifuge is a kind of widely used separation machinery, and its critical piece is a rotary drum that has taper video disc group and nozzle, and during seperator work, rotary drum rotates at a high speed, utilizes centrifugal force to realize feed separation in clearance between two dishes.The working speed of disk centrifuge rotary drum vibration occurs easily up to 4000～20000 rev/mins in operation process.Existing disk centrifuge rotary drum all adopts vertical the disturbing property axle construction of lower support, and power is by the lower end input of axle.Because the rotary drum center is above bearing block, when material skewness in the rotary drum formed centre-of gravity shift, the moment that gravity produces strengthened the distortion of disturbing property axle, thereby produced more violent vibration, influenced the working life of separating effect and machine.In addition, also more complicated of the dash hermetically-sealed construction of rotary drum axle lower mechanical drive disk assembly.
The utility model content
In order to simplify existing disk centrifuge rotary drum axle support structure, improve stable working.The utility model provides a kind of suspention rotary drum disk centrifuge, the rotary drum of this disk centrifuge adopts the suspension type supporting structure, drum vertically is suspended on the elastic support of frame, can rely on gravity effect automatic straightening off-centre during rotary drum work, improved smoothness of operation, power is imported into by rotary drum axle upper end simultaneously, does not also need the dash seal between rotary drum axle and the fuselage.
The technical scheme that its technical problem that solves the utility model adopts is: rotary drum is by in the main shaft container that vertically fuselage constitutes about being suspended in, the main shaft upper end is installed on the spindle bearing by bearing, the lower end of main shaft and rotary drum does not have supporting member, and spindle bearing is placed on the seperator housiung separator by elastic support.A belt pulley is installed on the main shaft top, and during seperator work, drive motor drives main shaft by belt transmission and rotary drum rotates at a high speed.
One of reason of seperator running vibration is that working speed produces resonance near critical speed.Because the rotating speed of rotary drum is very high, adopt elastic support can reduce support stiffness, reduce the intrinsic frequency of system, avoid the generation of covibration; Simultaneously can also play the vibration isolation effect, reduce the vibration on seperator frame and basis.
The Another reason of seperator running vibration is because the centrifugal force that rotary drum is eccentric and the material skewness produces.Rotary drum adopts the mounting means of going up the vertical suspention of fulcrum, can the center of gravity of rotary drum be drawn close to rotation by bearing elasticity automatic straightening off-centre at work, reduces the vibration of rotary drum.
The utility model utilizes the belt pulley of rotary drum axle upper end to drive main axis rotation.Belt transmission is simpler than gear transmission structure, and buffer shock-absorbing performance is preferably arranged, and can reduce the influence of vibration to motor and transmission system.Main shaft belt pull compensation arrangement is an adjustable radial elastic bearing, be installed in the side that spindle bearing bears belt pull, effect aspect two is arranged in the utility model: for spindle bearing provides radial support power, compensation is because the main-shaft axis inclination that belt pull produces; Secondly, the flexible member in the compensation arrangement is with belt, for spindle bearing provides a radial support with vibration damping, vibration isolation effect.
The utility model compared with prior art reduces the disk centrifuge vibration in when operation from many aspects, simplifies spindle support structure simultaneously, has following advantage:
1. centrifugal reel adopts vertical sus-pension to install on the elastic support of frame to move, at work by bearing elasticity automatic straightening off-centre, reduce because the rotary drum vibration that eccentric mass brings.
2. utilize elastic support to reduce support stiffness, reduce the intrinsic frequency of system, avoid the generation of covibration; Also has vibration isolating effect simultaneously.
3. utilize main shaft belt pull compensation arrangement to guarantee the vertical of main-shaft axis, and reduce the radial vibration of spindle bearing.
4. power is imported into by rotary drum axle upper end belt pulley, does not need the dash seal between rotary drum axle and the fuselage, simplifies spindle support structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structure chart of the present utility model.
Among the figure: 1-driving belt, 2-adjusting screw(rod), 3, the 5-nut, the 4-rubber buffer, 6-lubricating oil outlet joint, 7-spindle pulley, the 8-sealing ring, 9,11, the 14-bearing, the 10-upper spindle, 12-lubricating oil inlet joint, 13-spindle bearing, 15-suspension rod, 16-machine dish, the 17-video disc shelf, 18-nozzle, 19-video disc group, 20-rotary drum lower cover, 21-support, fuselage under the 22-, the 23-locking nut, 24-rotary drum body, 25-rotary drum lid, the 26-retaining ring, the last fuselage of 27-, 28-bottom main shaft, the 29-shaft coupling, 30-nut, 31-screw rod, the 32-crossbeam, 33-rubber buffer, 34-bearing.
The specific embodiment
Embodiment is described in detail the present invention below in conjunction with accompanying drawing.
The upper spindle of suspention rotary drum disk centrifuge is bearing in the dead eye of spindle bearing 13 by two groups of bearings 9,11,14 up and down, and the main shaft top connects spindle pulley 7 by flat key.During seperator work, drive motors drives the upper spindle rotation by driving belt 1, and drives bottom main shaft 28 and whole drum by shaft coupling 29.Rotary drum is made up of parts such as rotary drum body 24, rotary drum lid 25, retaining ring 26 and rotary drum lower covers 20, and whole drum is suspended on the main shaft, does not contact with fuselage 22,27 up and down.The weight of rotary drum passes to seperator crossbeam 32 by what rubber buffer 33, screw rod 31 and nut 30 constituted elastic support.The seperator working portion also comprises parts such as video disc shelf 17, video disc group 19, nozzle 18 and material pipe.
Because driving belt 1 can produce the tensile force of horizontal force, make main shaft that axis take place on elastic support.By adjusting the nut 3,5 on the main shaft belt pull compensation arrangement, mobile adjusting screw(rod) 2 makes main-shaft axis get back to the plumb position.Rubber buffer 4 can play radially vibration damping and vibration isolation effect to axis system.
