Description
Technical field
The present invention relates to a kind of screening plant, particularly, relate to a kind of two-stage type steel ball sieve.
Background technology
Accurate steel balls is industrially widely used, comprise the fields such as Aeronautics and Astronautics, bearing, motor, highly sophisticated device, valve, oil, battery all can use, in steel ball production process, always produce the excessive or too small defective steel ball of some diameters, this is great for industrial production harm.
At present, the screening of steel ball adopts usually manually to be carried out, the problem that this just causes, and cost of labor is high, error is comparatively large, labour intensity is large, and the problem that efficiency is very low.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of easy, efficient, cost of labor is low, recall rate is high two-stage type steel ball sieve.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of two-stage type steel ball sieve, comprise one-level sieve and secondary sieve, one-level sieve is arranged at the top of secondary sieve, and described one-level sieve comprises urceolus and one-level sieve bucket; One-level sieve bucket is located in urceolus, and distance is between the two greater than the diameter of screened steel ball; One-level sieve bucket bucket wall is provided with some penetrating round sieves, and described screen-aperture is slightly larger than screened steel ball size; The bottom of one-level sieve bucket is connected with motor by rotating shaft; The bottom of urceolus is provided with discharging opening;
Described secondary sieve comprises urceolus and secondary sieve bucket, and the screen-aperture on secondary sieve bucket bucket wall is slightly less than the diameter of screened steel ball, and other structure is sieved identical with one-level.
Preferably, the sieve aperture that described one-level sieve bucket and secondary sieve on bucket longitudinally linearly arranges; The rib to bucket inner process is provided with between sieve aperture on adjacent straight line; The height of described rib is 0.2-0.5 times of steel ball size.Rib extends to bottom from the top of bucket.
After increasing this rib, steel ball can be made when sieving bucket rotation to move more violent, avoid piling up, in addition, motor intermittence is set and rotate and reverse effect meeting better.
Preferably, the central axis place tangent plane of described one-level sieve bucket and secondary sieve bucket is isosceles inverted trapezoidal, is set to isosceles inverted trapezoidal, steel ball can be made when centrifugal motion, do ascending motion, avoid the accumulation of steel ball, through multiple authentication, best results when the extended line angle of two waists of inverted trapezoidal is 75 degree.
Preferably, the top of described one-level sieve bucket and secondary sieve bucket also has a bung, and described bung is conical, and conical top extends in bucket; Described bung is provided with handle.The effect of conical bung be steel ball when doing ascending motion, bung can by rise to top steel ball valid round under, make the motion of steel ball become a circulation, repeatedly screen while avoiding accumulation.
Preferably, tangent plane top, the axis place angle of described conical bung is 120 degree, and now steel ball can by under bullet to greatest extent, and shuttling movement is the fastest.
operation principle of the present invention and effect as follows:
Batch steel ball is put into the one-level sieve bucket of one-level sieve, open motor, one-level sieve bucket starts to rotate, steel ball then does centrifugal motion and extrudes towards bucket wall, due to the diameter that the screen-aperture on one-level sieve bucket is only slightly larger than qualified steel ball, therefore, qualified steel ball with only can enter urceolus by sieve aperture through too small steel ball, the excessive defective steel ball of diameter is then left in one-level sieve bucket.
The steel ball be thrown in one-level sieve urceolus enters secondary sieve by the discharging opening of urceolus bottom, aperture due to secondary sieve bucket sieve aperture is slightly less than the aperture of qualified steel ball, therefore, cross small ball can enter secondary sieve urceolus through sieve aperture, be recovered further, qualified steel ball is then screened out to be stayed in secondary sieve bucket, completes screening.
By above screening, qualified steel ball is separated quickly with defective steel ball, substantially increases operating efficiency, has saved human cost, and is fixed due to screening index, avoids to think the error of screening.
