The specific embodiment
For let above and other objects of the present invention, feature and advantage can be more obviously understandable, hereinafter is special lifts preferred embodiment, and conjunction with figs., elaborates as follows.
The water-coal-slurry vibratory sieve 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 set inside have 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 the both sides of sieve nest 2 respectively.
Among the present invention, two vibrating motor 3a and 3b start simultaneously, but direction of rotation is opposite, and wherein 1 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.
Among the present invention, 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 be connected with on the cell body " " ten " font oscillating plate 7 can comprehensively vibrate, make sieve comparatively thorough.
Among the present invention, 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 distribution of middle vertical plane mirror image during motion, 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 weighting block and fixing weighting block, adjustable weighting block and fixedly the angle of weighting block can adjust, and adjustable weighting block is consistent with the angle of fixing weighting block in two weight blocks.Open the vibration end shield of vibrating motor, unclamp adjustable weighting block pinching screw after, change adjustable weighting block and fixedly the angle of weighting block can adjust the size of exciting force, i.e. the size of amplitude, and satisfy the requirement of different productivity ratio.Attention: adjustable weighting block is consistent with the angle of fixing weighting block in two weight blocks.
Further, vibration be connected with on the cell body " " ten " font oscillating plate 7 can comprehensively vibrate, make sieve comparatively thorough.
Further, the bottom of supporting seat is provided with satisfied following requirement of coefficient of elasticity of rubber spring: at full load spring sinking 2-4cm.
Operation principle of the present invention is following:
Sieve nest 1 both sides of vibratory sieve are equipped with vibrating motor 3a and 3b, 2 several startups simultaneously, but direction of rotation is opposite, and the weight block of two vibrating motors is owing to the rigid relation of cell body, and " chasing " is synchronous automatically, and switched in opposite.As shown in Figure 4: two weight blocks produce centrifugal intertia force P from 1, P cancels out each other from 2 cross component force P side, the direction of vibration component P synthetic reciprocal directed exciting force P that shakes realizes screening.
