Description
The utility model relates to a kind of inertia vibrating screen that is used to sieve material, particularly twin shaft translation vibratory sieve.
Employed all kinds of inertia vibrating screens normally are made up of screen box, base and vibrator etc. both at home and abroad at present, and vibrator comprises motor and eccentric matter pouring weight.The rotation of motor drives eccentric massblock promptly produces a centrifugal intertia force (exciting force), thereby makes the vibratory sieve motion; When the centre of force of centrifugal intertia force overlapped with the whole barycenter of vibratory sieve screen box, vibratory sieve integral body was made translational motion, and the movement locus of each point is identical with the center of mass motion track on the screen box, and the movement locus of barycenter depends on the Changing Pattern of exciting force fully.The vibrator that adopts in producing at present has two kinds of single shaft and twin shafts.The single shaft inertia shaker vibrator, because the size of the centrifugal inertial force of its generation is constant all the time in rotary course, thereby the movement locus of each point can only be " circle " on the screen box, this " circle " type vibratory sieve does not often satisfy the needs of a lot of screenings and transportation work, therefore in 93239430.2 patents, the eccentric massblock that is arranged in the existing single shaft inertia shaker vibrator on the motor shaft is replaced by the single file star-wheel internal-gearing planet gear mechanism that has eccentric massblock.When motor rotates, planetary gear both rotated around the motor shaft center with bent axle, again around the bent axle rotation, the barycenter of the eccentric block on it in motion process apart from the distance at machine shaft center with regard to the generating period variation, the hodograph of its exciting force vector also changes thereupon, thereby makes vibratory sieve do pattern vibrations such as corresponding circle, straight line, ellipse.This single-shaft vibrating screen is simple in structure, the screening efficiency height, but owing to certain reason of manufacture view, do not apply aborning as yet at present.As for the double shaft inertia shaker vibrator that uses in producing at present, the vibration shape that they produced has only two kinds on " circle " type and " straight line " type, " circle " vibration shape bolting speed and mass transport speed are all slower, " straight line " is though the type vibratory sieve has higher solid phase particles transporting velocity, but there is throwing dead band (acceleration is zero direction), for the solid phase particles of plug in sieve aperture, be difficult to from sieve aperture, dish out, easily stop up sieve aperture (promptly producing " screen blinding " phenomenon).
The purpose of this utility model is to provide a kind of compact conformation, can realize the double shaft inertia shaker of the balanced elliptic vibration shape, improving screening efficiency and transporting velocity, and can avoid the generation of " screen blinding " phenomenon.
For achieving the above object, the utility model adopts following technique direction: vibratory sieve is by screen box (1), and base (2) and vibrator compositions such as (3), vibrator (3) comprise that motor (4) and two have eccentric mass m

The motor (4) that the utility model adopts can be anti-vibration motor (4 '), also can be shock electric machine (4 ").The appropriate location of motor mounting on screen box, when motor is worked, two of drive disk assembly (gear or two-sided synchronous band) drives that are connected on the motor output shaft have the eccentric shaft reverse rotation that does not wait eccentric quality, produce one immediately by " ellipse " or " circle " or " straight line " periodically variable centrifugal intertia force (exciting force), thereby make the vibratory sieve screen box realize translation " ellipse " or " circle " or " straight line " motion.
Advantage of the present utility model is: (1) is because vibratory sieve can be made elliptical vibration, oval " major axis " is the component of strengthening chip removal, " minor axis " is the component that promotes to be sized the saturating sieve of material, thereby both improved material and on compass screen surface, sieved and transporting velocity, obviously reduce the generation of " screen blinding " and " sticking screen " phenomenon again, thereby the treating capacity of material is improved greatly than " circle " type and " straight line " type vibratory sieve.(2) motor mounting is on the vibratory sieve screen box, compact conformation.When (3) adopting two-sided synchronous band transmission, can make the vibratory sieve work noise little, and need not to lubricate, avoid pollution environment; And when adopting gear drive, can make vibratory sieve guarantee higher reliable transmission.The utility model is not only applicable to oilfield drilling liquid Development Engineering, and can be used for carrying out the industrial circle such as chemical industry, mine, food of material screening, conveying.
