The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
The utility model comprises that isolation spring 1, screen box 5, screen cloth 6, screen cloth damage automatic detection device 7, frame 8, vibrational system 9, transmission device 10, automatic start-stop device 15 and centralized control system (not shown) etc. and form (Fig. 1).
As shown in Figure 1, the control section of automatic start-stop device (only suitable magnetic powder) produces circuit by signal acquisition circuit, on-off circuit, triggering signal and forms, described signal acquisition circuit is provided with sensor, controllable silicon and trigger impulse transformer thereof, described sensor is the sensor coil that intercouples, two coil spacings are wound on the non magnetic pipe, be connected in the feed pipe pipeline, when in the pipeline iron powder being arranged, coil sends enabling signal because of couple current, making start pulse signal produce circuit starts working, send trigger impulse, controllable silicon work; When not having material on the screen cloth, on-off circuit disconnects, and trigger impulse stops, and vibrator is shut down.Automatic start-stop has avoided the screen cloth zero load to shake by force, can prolong screen life-span, reduces maintenance time.
As shown in Figure 1, defeated net drum 2 is arranged on the frame 8 of screen(ing) machine, screen cloth one end is wound on the defeated net drum 2, the screen cloth of failing net drum 2 outputs is arranged on the leading stream directive wheel 4 of screen(ing) machine, the back water conservancy diversion directive wheel 13, as the work section screen cloth of screen(ing) machine, front jockey wheel 3, back directive wheel 17 are arranged on screen box upper support screen cloth; The other end of screen cloth is arranged on the net drum 18.When screen cloth damaged, the motor (not shown) drove the rotation of net drum 18 rotation traction traction screen cloth active sections and damages screen portion disengaging work section screen(ing) machine continuation operate as normal.
