Abstract
The invention discloses a big granularity vibrating lip screen, which belongs to a classification device of the coal preparation plant, the invention is mainly used for classification of gross coal, and is also used for classification of other big block materials; the screen surface adopts the ladder shape space grid structure for solving the problem occurred when the big block slice stone enters the lower part of the screen: a lateral plate of the screen frame is propped on a base, and is totally out of the joining vibration; an excitation beam is arranged under the ladder shape screen mesh frame, vibration generators are arranged on the two ends of the excitation beam, a double-output shaft electromotor drives the vibration generators by a shaft coupling, then the exciting force is transferred to the ladder shape screen mesh frame. Therefore, the invention has low overall height, small driving power, simple structure and reliable running.
Description
Technical field
The present invention relates to a kind of large granules vibrating sizing screen, be mainly used in colliery run-of-mine coal (ROM coal) classification, also can be used for the classification of various bulk materials, belong to cleaning unit.
Background technology
Current, circular shale shaker is adopted in the classification of colliery coarsegrain material more, and joins the mode of rod screen frame (unit), and the whole height of sieve is bigger, and the pipe beam is more, and structure is loaded down with trivial details relatively, and mass of vibration is big, and energy consumption is also high.Can't solve simultaneously the bulk slabstone and enter sieve down, the problem that causes subordinate equipment to damage.
Summary of the invention
The present invention is directed to the problems referred to above, proposed a kind of large granules vibrating sizing screen, it is little, simple in structure to have a whole height, little, the characteristic of low energy consumption of mass of vibration, and solve the bulk slabstone and enter problem under the sieve.
Technical scheme of the present invention is: a kind of large granules vibrating sizing screen comprises screen frame, trapezoidal screen bed base, exciting beam, vibrator, two shaft motor, flexible coupling, base and vibration absorber is characterized in that: screen frame is made up of coaming plate and support, and screen frame is supported and fixed on the base by screen frame.Trapezoidal screen bed base is fixed on the base by spring, and trapezoidal screen bed base is made of round steel, supporting steel plate.Wherein laterally round steel passes vertical elongated supporting steel plate formation basic framework, and short supporting steel plate is overlapped on the adjacent transverse round steel, is welded with wear-resisting round steel respectively, the trapezoidal grid structure of whole formation on vertical elongated supporting steel plate and the short supporting steel plate.Trapezoidal screen bed base has two exciting beams, and vibrator is equipped with at exciting beam two ends, and vibrator links to each other with two shaft motor by flexible coupling.Motor is by being supported and fixed on the base.
Its good effect is: compass screen surface adopts the trapezoid space grid structure, has solved the bulk slabstone and has entered problem under the sieve; The screen frame side plate does not have the protrusion hilltop, and whole height is very low, and does not join fully and shake, and mass of vibration is greatly reduced; Greatly improving aspect bulk strength, the rigidity, thereby improving reliability of operation, drive motor power also reduces.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is the front view of large granules vibrating sizing screen;
Fig. 2 is the side view of large granules vibrating sizing screen.

The specific embodiment
As shown in Figure 1 and Figure 2, this sieves mainly by screen frame 1, trapezoidal screen bed base 9, exciting beam 3, vibrator 4, two shaft motor 6, flexible coupling 5, base 8 and reduce device and form.Screen frame 1 is made up of coaming plate and support, and screen frame 1 supports 7 by screen frame and is fixed on the base 8.Trapezoidal screen bed base 9 is fixed on the base 8 by spring 2, and trapezoidal screen bed base 9 is made up of round steel, supporting steel plate.Trapezoidal screen bed base 9 has two exciting beams 3, and vibrator 4 is equipped with at exciting beam 3 two ends, and vibrator 4 links to each other with two shaft motor 6 by flexible coupling 5.Motor 6 is by being supported and fixed on the base 8.
In Fig. 3, Fig. 4, laterally round steel 10 passes vertical elongated supporting steel plate 13 formation basic frameworks, short supporting steel plate 12 is overlapped on the adjacent transverse round steel 10, is welded with wear-resisting round steel 11 respectively, the trapezoidal grid structure of whole formation on vertical elongated supporting steel plate 13 and the short supporting steel plate 12.
