The specific embodiment
For above-mentioned and other objects, features and advantages of the present utility model can be become apparent, preferred embodiment cited below particularly, and cooperate accompanying drawing, be described in detail below.
Water-coal-slurry vibrating screen comprises piece blow tank 1, sieve nest 2 and exciting source.Piece blow tank 1 is arranged on an end of sieve nest 2, and sieve nest 2 inside are provided with vibration cell body and trapezoidal screen cloth (not shown) of stainless steel, and exciting source is two vibrating motor 3a and 3b, is installed in respectively the both sides of sieve nest 2.
In the utility model, two vibrating motor 3a and 3b start simultaneously, but direction of rotation is opposite, and wherein 2 four arms of angle of sieve nest are provided with supporting seat 5, and the bottom of supporting seat 5 is provided with rubber spring 6.
In the utility model, wherein 2 four arms of angle of sieve nest are provided with supporting seat 5, and the bottom of supporting seat is provided with rubber spring 6.
Further, vibration is connected with " ten " font oscillating plate 7 on the cell body, can comprehensively vibrate, make sieve comparatively thorough.
In the utility model, the exciting piece that two vibrating motor 3a and 3b drive is the identical weight block of distribution of weight and shape, remains on the middle vertical plane mirror image during motion and distributes, and in order to the vibration about balance, only keeps the vibration of vertical direction.And the rotating speed of two vibrating motors is 100-300 rev/min.Two weight blocks comprise adjustable offset pouring weight and fixing weighting block, the adjustable offset pouring weight and fixedly the angle of weighting block can adjust, and the adjustable offset pouring weight is consistent with the angle of fixing weighting block in two weight blocks.Open the vibration end shield of vibrating motor, unclamp adjustable offset pouring weight pinching screw after, change adjustable offset pouring weight and fixedly the angle of weighting block be the size of capable of regulating exciting force, i.e. the size of amplitude, and satisfy the requirement of different productivity ratio.Attention: the adjustable offset pouring weight is consistent with the angle of fixing weighting block in two weight blocks.
Further, vibration is connected with " ten " font oscillating plate 7 on the cell body, can comprehensively vibrate, make sieve comparatively thorough.
