Abstract
The invention relates to a vibrating screen with spiral track, which belongs to the field of vibratory screening machinery. The vibrating screen can enable material particles to achieve spiral motion state on a screening surface, solves the problem of hole blocking by difficult-to-be-screened materials or critical particles, and increases the percent through screen. The vibrating screen consists of a screen box, a screen surface, a double-shaft vibration source, lateral vibration sources, an anti-vibrating spring and a support, wherein the double-shaft vibration source enables the screening box to move in rectilinear motion track in the specified vibration direction in the longitudinal plane; two lateral vibration sources with the same performance are symmetrically arranged on the two sides of the screen box and rotate in the same direction to make the screen box generate a lateral circular motion track; and the vibration composition of the double-shaft vibration source and the lateral vibration sources makes the screen box generate a spiral motion track. The vibrating screen is used for the screening of difficult-to-be-screened materials, and is characterized by compact structure, stable operation and high screening efficiency.
Description
Technical field:
The invention belongs to the vibration screening machinery field, be mainly used in the screening of every profession and trade difficult screened material, can make material particles on compass screen surface, realize spiral movement locus, solve difficult screened material or critical particle hole clipping problem, improve saturating sieve probability.
Background technology:
In the existing conventional vibratory sieve; the screen(ing) machine vibration can only realize three kinds of tracks: straight line, circle and ellipse; these three kinds of tracks all are to take place in the fore-and-aft plane of vibratory sieve; therefore make material particles in fore-and-aft plane, have only the motion of X-direction and Y direction to sieve power thoroughly; particle does not stress in Z-direction, and in a single day difficult like this sieve particle or irregular critical particle are stuck in the sieve screen apertures, just is difficult to find suitable loading angle ejection or come off; and then the formation plug-hole, influence screening efficiency.
Summary of the invention:
The invention provides a kind of vibrating screen with spiral track, during the screen(ing) machine vibration, screen box and compass screen surface produce spiral movement locus, make material particles motion of existing X-direction and Y direction on compass screen surface sieve power thoroughly, there is the motion of Z-direction to sieve power thoroughly again, make material particles not hole clipping, not network blocking, the screening efficiency height.
The present invention is achieved by the following measures.A kind of vibrating screen with spiral track is made up of screen box, compass screen surface, twin shaft exciting source, the horizontal exciting source that shakes, shock-absorbing spring and bearing, it is characterized in that: the twin shaft exciting source makes screen box in accordance with regulations vibrating direction angle in fore-and-aft plane do straight-line trajectory; Two identical horizontal exciting sources that shake of performance are arranged symmetrically in the screen box both sides, and rotation makes screen box produce horizontal circular motion track in the same way; The synthetic screen box that makes of the vibration of twin shaft exciting source and the horizontal exciting source that shakes produces spiral movement locus.
Two axles of twin shaft exciting source are designed to the constant speed reverse rotation, and it produces the position of making a concerted effort will pass through the screen box barycenter, and vibrating direction angle can be chosen in 30～60 ° of scopes according to the production capacity demand; The axis of two horizontal exciting sources that shake is parallel with the side plate on the screen box, and according to the difference that is sized material, its axis and compass screen surface angle are chosen in 0～180 ° of scope; The installation site of two horizontal exciting sources that shake can laterally be as the criterion the line of its central point by the screen box barycenter; The version of twin shaft exciting source and the horizontal exciting source that shakes can be inertia vibration generator, also can be vibrating motor; The rotating speed of twin shaft exciting source and the horizontal exciting source that shakes equates or is unequal; Compass screen surface is 1～3 layer; The inclination angle of compass screen surface is 0～25 °; In order to strengthen the stability of screen(ing) machine operation, bearing is provided with lateral damper.
What vibratory sieve of the present invention was realized is spiral movement locus, solves difficult screened material or critical particle hole clipping problem, improves saturating sieve probability, and the screen(ing) machine compact conformation operates steadily, the screening efficiency height.
