Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, technical scheme described in the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, shown in Fig. 3, automatically cleaning vibratory sieve described in the present embodiment, comprise: lower sieve nest 9 and the top cover 6 that is arranged on lower sieve nest 9 tops, the junction of top cover 6 and lower sieve nest 9 is provided with U-shaped sealing strip 1, U-shaped sealing strip 1 makes between top cover 6 and lower sieve nest 9 in sealing state, in lower sieve nest 9, be provided with screen cloth 3, the edge of screen cloth 3 is fixed on lower sieve nest 9 by screen cloth support 7, side at top cover 6 is provided with large material outlet 22 along the tangential direction of screen cloth 3, be provided with screw mandrel 2 at the center of lower sieve nest 9, screw mandrel 2 lower ends are fixedly connected with lower sieve nest 9, screw mandrel 2 upper ends are provided with pad 5 and clamping plate 4, pad 5 and clamping plate 4 clamp screen cloth 3 and make the centre of screen cloth 3 to upper process, make screen cloth 3 form umbrella-shaped structure, like this in the time of material screening, can not be by the diffusion towards periphery under the effect of vibration force and gravity of the large material of screen cloth 3, finally discharge from large material outlet 22.Between top cover 6 and screen cloth 3, form raw material feed cavity 24, the cavity of screen cloth 3 belows is blanking chamber 25; Center on top cover 6 is provided with charging aperture 10, be provided with two charging holes for subsequent use in the both sides of charging aperture 10, on charging hole for subsequent use, be provided with fixed cap 13 by bolt, in the time that a charging aperture 10 can not meet need of production, can open fixed cap 13, enable charging hole for subsequent use temporarily, meet large-scale production needs; On top cover 6, be also provided with a manhole, on manhole, be provided with access cover 17 by hinge 14, access cover 17 is locked on top cover 6 by locking bolt 15, facilitates professional equipment is safeguarded and overhauled.In addition, be provided with two reinforcements 19 at the upper surface of top cover 6 and reinforce top cover 6, lower sieve nest 9 bottoms are provided with the discharge barrel 18 communicating with blanking chamber 25, discharge barrel 18 outer surfaces are provided with two vibrating motors 21, discharge barrel 18 bottoms offer discharging opening 11, lower sieve nest 9 outer surfaces are also evenly provided with four rubber springs 12, and when work, the bottom of rubber spring 12 is fixed on steelframe platform, plays the effect of damping, buffering; In lower sieve nest 9 below screen cloth 3, be fixed with horizontally disposed web plate 8, on web plate 8, be covered with the aperture passing through for material, on web plate 8 plate faces, be placed with two rubber rotating wash bowls 20; When work, Vibration on Start-up motor 21, vibrating motor 21 drives lower sieve nest 9 to vibrate, screen cloth 3 and web plate 8 also corresponding beginning vibrate, be placed on rubber rotating wash bowl 20 on web plate 8 owing to being subject to the vibration force of web plate 8 bob and constantly impact screen cloth 3, thereby the material that accumulates in screen cloth 3 surfaces or block screen cloth 3 meshes is cleaned out.
Above-mentioned automatically cleaning vibratory sieve operation principle is as follows: when work, Vibration on Start-up motor 21, vibrating motor 21 drives lower sieve nest 9 to vibrate, charging aperture 10 starts charging, material drops on the screen cloth 3 that is umbrella, little material can be discharged from discharging opening 11 by screen cloth 3 and web plate 8, affects meeting to diffusion around screen cloth 3 and large material is subject to vibration force and gravity on screen cloth 3, finally discharges from large material outlet 22.Simultaneously, when lower sieve nest vibration, drive web plate 8 to vibrate together, two rubber rotating wash bowls 20 that are placed on web plate 8 are constantly upwards beated and constantly impact screen cloth 3 owing to being subject to the vibration force of web plate 8, clean out the material that accumulates in screen cloth 3 surfaces or block screen cloth 3 meshes, ensure the screening effect of screen cloth 3, realize self-cleaning function.
Because the upwards effect that impacts to screen cloth of rubber rotating wash bowl, makes material to gather or to block screen cloth mesh in screen surface when vibratory sieve work, in the situation that need not shutting down, obtain self-cleaning effect, improve operating efficiency.In addition, because the umbrella-shaped structure of screen cloth is being subject under the effect of vibration force and gravity the not large material by screen cloth, past diffusion around gradually, and finally discharge from large material outlet, the velocity of discharge of large material promoted, effectively reduce gathering of material on screen cloth, improved operating efficiency.
