Description

Eccentric block vibration exciter formula complex-frequency vibrating screen
Technical field
This is suitable for novel a kind of eccentric block vibration exciter formula complex-frequency vibrating screen that relates to, and belongs to a kind of thin material screening machinery of industries such as being specially adapted to coal, building materials, cement, pottery, metallurgy.
Background technology
Present screening machine mostly is high frequency vibrating formula and complete machine oscillation formula.Vibrating formula high frequency sieve has very strong classifying capability, but when screen(ing) machine had very small inclination, conveying capacity was poor, influences disposal ability, and during than high inclination-angle, shared factory building height is too big.Even complete machine oscillation formula level also has very strong conveying capacity when installing, but grading effect is relatively poor, and is subjected to the restriction of structural strength.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of eccentric block vibration exciter formula complex-frequency vibrating screen, it is by the direct exciting screen box of primary vibration exciter (low-frequency vibration system), while seconary vibration exciter (high-frequency electromagnetic vibrator) is the exciting screen cloth again, make compass screen surface produce complex vibration, screen box low frequency large-amplitude vibration helps carrying, and compass screen surface is additional to have the high frequency small amplitude motion to be beneficial to classification.
The purpose of this utility model is achieved in that
The sieve box side plate installed inside has angle steel, the vertical tensioning of screen cloth places on the angle steel, the sieve box side plate outside is equipped with the high-frequency electromagnetic vibrator, it is by electromagnet, armature, rubber spring, compositions such as power transmission bolt, electromagnet is installed in electromagnetic exciter and puts outward, the electromagnetic exciter overcoat is fixed on the screen box, armature is built on the power transmission bolt admittedly, rubber spring is by last, lower platen, round nut is fixed on the power transmission bolt, the lower end of power transmission bolt is hinged with the driving vibrating arm, the other end that drives vibrating arm is fixedlyed connected with transverse axis, transverse axis is installed in screen cloth below in the screen box, be set with the twist mode rubber spring on the square diameter of axle at its two ends, be set with tightening watt cover on the twist mode rubber spring cylindrical, the outer pocketed springs tightening seat of tightening watt cover, it is bolted on the sieve box side plate, shaker arm is installed on the transverse axis, and the shaker arm upper end is equipped with rubber cap, and rubber cap tightly holds in the palm screen cloth.
Outside the fixedly connected primary vibration exciter on the screen box (low-frequency vibration system), in the sieve box side plate outside seconary vibration exciter (high-frequency electromagnetic vibrator) is installed also, primary vibration exciter comprises two eccentric block vibration exciters that specification is identical, across the top that is consolidated in screen box, two eccentric block vibration exciters link to each other with two motors by truck drive shaft respectively, provide exciting force to drive compass screen surface.Motor makes the eccentric block vibration exciter main shaft gyration by truck drive shaft, and the inertia force that the eccentric block gyration on the main shaft produces makes screen box vibration relatively along inclined direction, and material is travelled forward.
One be the high-frequency electromagnetic vibrator of 50Hz by the direct exciting screen cloth of elastic system, strengthen the oscillation intensity of compass screen surface, strengthen the self-cleaning ability of compass screen surface, prevent sieve pore blockade, be beneficial to classification, dehydration, desliming, the de-mediated of fine.Another comes the exciting screen box for the nearly straight-line oscillation of low frequency of 25Hz, to strengthen the transporting velocity of material, overcomes the essential transporting velocity that strengthens the screen box inclination angle with the raising material of simple vibration sieve, thereby avoids the bigger shortcoming of screen(ing) machine setting angle.Screen cloth is subjected to the exciting perpendicular to the 50Hz of compass screen surface on the one hand like this, compass screen surface integral body has participated in the vibration with screen box again on the other hand, thereby realize the complex vibration of compass screen surface, reach and not only improve the saturating sieve ability of compass screen surface but also improve two purposes of the transporting velocity of material on compass screen surface.
This is suitable for the novel following advantage that compared with prior art has:
1, utilizes electric cabinet can regulate the high frequency amplitude arbitrarily, thereby can regulate feeding coal according to material properties and technological requirement;
2, two exciting force excitings are beneficial to stock grading, dehydration, desliming, de-mediated and conveying, and it is long-pending that the while discharge end does not have bank;
3, sieve aperture is difficult for stopping up, the saturating screen capacity height of difficult sieve, and treating capacity is big;
4, screen cloth adopts the stainless steel wire mesh grid, and lower floor is the holder net of crin macropore, and the upper strata is the composite web that two-layer stainless steel wire mesh grid bonds together, composite web has very high percent opening, have certain rigidity, be convenient to tensioning, smooth installation, and improve the service life of screen cloth;
5, simple in structure, easy for installation, long service life.
