Description
Technical field
The utility model relates to a kind of screening plant, particularly, relates to a kind of two-stage type steel ball sieve.
Background technology
Accurate steel balls is widely used industrial, comprise that the fields such as Aeronautics and Astronautics, bearing, motor, highly sophisticated device, valve, oil, battery all can use, in the steel ball production process, always produce the excessive or too small defective steel ball of some diameters, harm is great for industrial production for this.
At present, the common employing of the screening of steel ball is manually carried out, the problem that cost of labor is high with regard to having caused for this, error is large, labour intensity is large, and the very low problem of efficient.
The utility model content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of easy, efficient, cost of labor is low, recall rate is high two-stage type steel ball sieve is provided.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of two-stage type steel ball sieve comprises one-level sieve and secondary sieve, and the 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 between the two is greater than the diameter of institute's screening steel ball; One-level sieve bucket bucket wall is provided with some penetrating round sieves, and described screen-aperture is slightly larger than the steel ball size that screens; 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 institute's screening steel ball, and other structure is identical with the one-level sieve.
Preferably, the sieve aperture on described one-level sieve bucket and secondary sieve bucket is vertically along arranged in a straight line; Be provided with between sieve aperture on adjacent straight line to the rib of bucket inner process; The height of described rib is 0.2-0.5 times of steel ball size.Rib extends to the bottom from the top of bucket.
After increasing this rib, sieve bucket can make the steel ball motion more violent when rotating, avoid piling up, in addition, arrange the motor intermittence rotate and reverse effect can be better.
Preferably, the central axis place tangent plane of described one-level sieve bucket and secondary sieve barrel is the isosceles inverted trapezoidal, is set to the isosceles inverted trapezoidal, can make steel ball when centrifugal motion, do ascending motion, avoid the accumulation of steel ball, through multiple authentication, the extended line angle of two waists of inverted trapezoidal is 75 best results when spending.
Preferably, the top of described one-level sieve bucket and secondary sieve bucket also has a bung, and described bung is taper shape, and extend in bucket at the circular cone top; Described bung is provided with handle.The effect of conical bung be steel ball when doing ascending motion, bung can will rise under the steel ball valid round at top, makes the motion of steel ball become a circulation, repeatedly screens when avoiding piling up.
Preferably, the axis place tangent plane top angle of described conical bung is 120 degree, and this moment, steel ball can be by under bullet to greatest extent, and shuttling movement is the fastest.
Operation principle of the present utility model and effect are as follows:
The batch steel ball is put into the one-level sieve bucket of one-level sieve, open motor, one-level sieve bucket begins to rotate, steel ball is done centrifugal motion and is pushed towards the bucket wall, because the screen-aperture on one-level sieve bucket is only the diameter that is 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 left in one-level sieve bucket.
The discharging opening of steel ball by the urceolus bottom that is thrown in one-level sieve urceolus enters the secondary sieve, be slightly less than the aperture of qualified steel ball due to the aperture of secondary sieve bucket sieve aperture, therefore, cross small ball and can see through the urceolus that sieve aperture enters the secondary sieve, further be recovered, qualified steel ball is screened out staying in secondary sieve bucket, completes screening.
By above screening, qualified steel ball is separated quickly with defective steel ball, has greatly improved operating efficiency, has saved human cost, and because screening index is fixed, and has avoided thinking the error of screening.
