Abstract
The utility model relates to a round double-beam oscillating screen, which belongs to the technical field of oscillating screen machinery and aims at solving the problem that the existing round oscillating screen has too high mass of vibration and complicated appearance, causing that the operation inertia force is greater, and the amplitude and vibration strength can not be enhanced. The overall structure of the oscillating screen is optimized. A screen box comprises two side plates and two screen surface support beams, which are riveted or welded, and the two screen surface support beams are provided with screen surfaces; a vibrator is arranged between the two screen surface support beams and positioned below the screen surfaces, and both ends of the vibrator are respectively arranged on the side plates at the two sides of the screen box; and the screen surface support beam which is positioned beside the feeding end of the screen box is provided with a rear block plate. The oscillating screen can be widely used for material rating operation in the industry of coal, mine, etc., and can obviously enhance screening efficiency and processing capacity.
Description
Technical field:
The utility model belongs to the vibration screening machinery field, is mainly used in the stock grading operation of every profession and trades such as coal, mine, improves the screening efficiency and the disposal ability of vibratory sieve.
Background technology:
In existing circular shale shaker, the screen box of screen(ing) machine all is made up of two relatively big side plate, several entablature and several sill or carriages of appearance and size, cause the screen box appearance and size of screen(ing) machine excessive, structure is not compact, make the mass of vibration of vibratory sieve big, operation inertia force is big, work is not steady, the destructive power of sieve box side plate and crossbeam also strengthens thereupon, and screen(ing) machine reduces service life; The mass of vibration of screen(ing) machine is excessive in addition, and the amplitude of screen(ing) machine and oscillation intensity also can't be strengthened, and influences its screening effect, and changes inconvenience, also will strengthen for design datas such as motor, bearing, springs, and manufacturing cost improves.
The utility model content:
The utility model provides a kind of twin beams circular shale shaker, screen box appearance and size is little, compact conformation, mass of vibration is special light, amplitude is especially big, is widely used in obviously improving its screening efficiency and disposal ability in the stock grading operation of every profession and trades such as coal, mine, by a plurality of tandem compounds, be convenient to the vibratory sieve large scale development in addition to screen box.
The utility model is realized by following measure.A kind of twin beams circular shale shaker, form by screen box, compass screen surface, vibrator, vibration absorber, bearing and transmission gear for electric motor, it is characterized in that: screen box is by two appearance and sizes compare less side plate and the riveted joint of two compass screen surface bearing cross beams or be welded to form, and is furnished with compass screen surface on two compass screen surface bearing cross beams; Vibrator is arranged between two compass screen surface bearing cross beams, and is positioned at the below of compass screen surface, and its two ends are installed in respectively on the side plate of screen box both sides; Compass screen surface bearing cross beam near the screen box feeding end is provided with the back striker plate.
In order to dwindle side plate appearance and size and to guarantee that the screening material does not splash the screen box outside, compass screen surface is 200～300mm apart from the backgauge height of side plate top edge; The compass screen surface bearing cross beam can be selected its cross sectional shape according to the width of screen box: rectangle, seamless pipe, H shaped steel or bending shape; The inclination angle of compass screen surface is 15～35 °; The frequency of screen box is 16.16～11.83Hz, and double-amplitude is 9～25mm.
A kind of whole screen(ing) machine of twin beams circular shale shaker is according to treating capacity and screening efficiency requirement, can a plurality of screen box tandem compound, to reach working condition requirement, reduce basic dynamic load; Wherein each screen box, compass screen surface can design different screen angles, different amplitude and different frequencies, with the generation of avoiding resonating.The utility model is convenient to the large scale development of equipment, the graded operation of alternative various circular shale shakers.
Description of drawings:
Accompanying drawing 1 and accompanying drawing 2 are structural representation of the present utility model, wherein Fig. 2 be the A of Fig. 1 to view, 1 is that screen box, 2 is the back striker plate for compass screen surface bearing cross beam, 9 for side plate, 8 for transmission gear for electric motor, 7 for bearing, 6 for vibration absorber, 5 for vibrator, 4 for compass screen surface, 3 among the figure.
The specific embodiment:
In conjunction with the accompanying drawings 1 and accompanying drawing 2 explanation one of them embodiment of the present utility model: a kind of twin beams circular shale shaker: SLY4020, form by screen box 1, compass screen surface 2, vibrator 3, vibration absorber 4, bearing 5 and transmission gear for electric motor 6, it is characterized in that: screen box 1 is by two appearance and sizes compare less side plate 7 and 8 riveted joints of two compass screen surface bearing cross beams or be welded to form, and is furnished with compass screen surface 2 on two compass screen surface bearing cross beams 8; Vibrator 3 is arranged between two compass screen surface bearing cross beams 8, and is positioned at the below of compass screen surface 2, and its two ends adopt high strength articulation hole bolt to be installed on the side plate 7 of screen box both sides respectively; Compass screen surface bearing cross beam 8 near screen box 1 feeding end is provided with back striker plate 9.Do not have entablature or other web beam on the screen box 1, compass screen surface bearing cross beam 8 is the web beam of screen box, is again the bearing cross beam of compass screen surface and material.Compass screen surface 2 is 250mm apart from the backgauge height of side plate 7 top edges; The cross sectional shape of two compass screen surface bearing cross beams 8 is rectangles, and the backboard 9 on the compass screen surface bearing cross beam 8 of screen(ing) machine feeding end is bending shape; The inclination angle of compass screen surface 2 is 20 °; The frequency of screen box 1 is 11.83Hz, and double-amplitude is 20mm, and design has a screen box in the screen(ing) machine, and width is 4000mm, and length is 2000mm, and mass of vibration is 4300kg.
