Description
Technical field
The utility model belongs to the vibration screening machinery field, the amplitude that mainly relates to the vibration sieve screen cloth is relative variation with vibration frequency, the screen box of vibration sieve also participates in vibration simultaneously, can effectively improve the compound vibration sieve of change movement locus of vibratory sieve disposal ability and screening efficiency.
Background technology
Vibration sieve normally adopts the high-frequency electromagnetic vibrator, drives the screen cloth dither by parts such as vibrating arm, rubber torsion spring, shaker arm and rubber caps, reaches the purpose of screening material.Because the amplitude of each electromagnetic vibrator is identical with operating frequency, so the amplitude of whole screen cloth also is identical with vibration frequency substantially.Has the ginseng little and power consumption advantage such as low of weight of shaking.But for some difficult screened materials, the perhaps screening of the thicker material of the bed of material on the compass screen surface, because the relative motion between the material particles is less, Zuo Yong chance is few each other, tends to occur solid accumulation or the not smooth problem of material walking, influences the screening of material." becoming the movement locus vibration sieve " is though solved this problem preferably, improved the disposal ability of vibration sieve, but the operation of material still is not ideal enough on the whole compass screen surface, solve at the inclination angle that needs to increase compass screen surface, so not only increase the height of screen(ing) machine, also reduced the screening effect of vibration sieve relatively.
The utility model content
The purpose of this utility model provides the compound vibration sieve of a kind of change movement locus, this vibration sieve is by the change movement locus of the relative variation generation of screen cloth amplitude and vibration frequency, and with the complex vibration of screen box body vibration, realization can improve the disposal ability and the screening efficiency of vibration sieve effectively to the screening of material.
The utility model is realized by following measure, mainly is made up of screen box, screen cloth, frame, screen cloth vibrating device and screen box vibrating device etc., and screen box is installed on the frame by vibration absorber.It is characterized in that: the screen cloth vibrating device mainly is made up of vibrator and shaker arm, and vibrator is arranged on the side of screen box, shaker arm be positioned at screen cloth below, organize screen cloth vibrating device vertically being arranged in order along screen box more.From the feeding end of screen box to discharge end, each is organized the amplitude of screen cloth vibrating device vibrator and descendingly successively decreases, ascendingly increases progressively, equates or unequal, each organize the vibration frequency of screen cloth vibrating device vibrator successively decrease from high to low, increase progressively from low to high, identical or inequality.Screen box is provided with the screen box vibrating device of being made up of vibrating motor or eccentric mass vibrator.
Except each amplitude of organizing screen cloth vibrating device vibrator equates, outside the identical prior art of vibration frequency, by screen cloth vibrating device vibrator amplitude and vibration frequency change,, can be combined into installation arrangement mode with the lower screen cloth vibrating device according to the needs of sieving technology:
A, from the feeding end of screen box to discharge end, each organizes descending the successively decreasing of amplitude of screen cloth vibrating device vibrator, vibration frequency is successively decreased from high to low or is increased progressively from low to high;

E, from the feeding end of screen box to discharge end, it is unequal that each organizes the amplitude of screen cloth vibrating device vibrator, vibration frequency is successively decreased from high to low or is increased progressively from low to high;
F, from the feeding end of screen box to discharge end, it is unequal that each organizes the amplitude of screen cloth vibrating device vibrator, vibration frequency is identical or inequality;
G, from the feeding end of screen box to discharge end, each amplitude of organizing screen cloth vibrating device vibrator equates that vibration frequency is successively decreased from high to low or increased progressively from low to high;
Perhaps h, from the feeding end of screen box to discharge end, each amplitude of organizing screen cloth vibrating device vibrator equates that vibration frequency is inequality.
Different according to the composition of material and ratio, organize that the screen cloth vibrating device arranges longitudinally along screen box can be equidistant or not equidistant more.According to the needs of screen area, the quantity of screen cloth vibrating device can be 2-9 group, is made up of two vibrators for every group, is installed in the both sides of screen box, also can be made up of a vibrator, is installed in a side of screen box.
The vibrator of screen cloth vibrating device is realized by electromagnetic vibrator, eccentric mass vibrator or vibrating motor.The eccentric mass vibrator is eccentric shaft or eccentric block formula vibrator, and is provided with additional eccentric block formula eccentric mass adjusting device.
The vibrator of screen box vibrating device is single shaft or twin shaft, and the oscillation trajectory that makes screen box is circular motion or straight-line trajectory.The eccentric mass vibrator is eccentric shaft or eccentric block formula vibrator, and is provided with additional eccentric block formula eccentric mass adjusting device.
During vibration sieve work, because the amplitude of each group screen cloth vibrating device and vibration frequency can reasonably combined regularly variations, material can form the movement locus of amplitude and vibration frequency increasing or decreasing rule on compass screen surface, also amplitude can be formed and vibration frequency is unequal, material becomes the movement locus of turbulent flow or fluidized state, add the complex vibration of screen box vibrating device, make the material on the compass screen surface pass through compass screen surface with the relative variation of amplitude and vibration frequency and the compound motion track of screen box vibration.
The beneficial effects of the utility model are because the vibration mode of vibration sieve screen cloth is to design according to the needs that sieve material, oscillation amplitude change is not only arranged, and vibration frequency change is arranged, in addition the body vibration of screen box.So the adaptability of screen(ing) machine is more intense, can be combined into the compound vibration sieve of the change movement locus of multiple screen movement form, adopt the method that becomes movement locus to sieve to material.Material no longer is clocklike to move on compass screen surface, but under the effect of the dual variation of amplitude and vibration frequency and screen box complex vibration, repeatedly produces collision and seethes, and makes the effectively saturating sieve of difficult screened material improve the disposal ability and the screening efficiency of vibration sieve.Can be applicable to the various vibration sieves that difficult screened material carried out classification.
