Description

Screen mesh pulling-out device of vibrating screen

Technical Field

The utility model relates to a shale shaker technical field, in particular to shale shaker screen cloth pull-out device.

Background

The vibrating screen operates by utilizing reciprocating rotary type vibration generated by vibrator excitation. The upper rotary heavy hammer of the vibrator makes the screen surface generate plane rotary vibration, the lower rotary heavy hammer makes the screen surface generate conical surface rotary vibration, and the combined effect makes the screen surface generate re-rotary vibration. The vibration locus is a complex space curve. The curve is projected as a circle in the horizontal plane and as an ellipse in the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotary weights. And the curve shape of the motion trail of the screen surface can be changed and the motion trail of the materials on the screen surface can be changed by adjusting the space phase angle of the upper and lower heavy hammers.

The screen cloth of large-scale reciprocating sieve needs periodic replacement, and the higher inconvenient of taking out in screen cloth position nevertheless leads to the user very loaded down with trivial details when changing the screen cloth to the practicality of shale shaker screen cloth has been reduced.
