Abstract
The utility model relates to an amplitude-decreasing banana vibrating screen, which belongs to the mechanical field of vibratory screening, and is designed mainly for increasing the screening efficiency of the vibrating screen. A vibration exciting device of the banana-shaped sieve vibrating screen consists of two vibrators, one vibrator is arranged at the material inlet end of a screen box, and the other vibrator is arranged at the material outlet end of the screen box; the distance between the two vibrators is 1/3 to 5/6 of the length of the screen box; the eccentric masses of the two vibrators are different, and the eccentric mass of the vibrator at the material inlet end is larger than that of the vibrator at the material outlet end, i.e. the amplitude of the material inlet end of the screen box is larger than that of the material outlet end. The rotation directions of the two vibrators are opposite, and the action line of the vibration resultant force passes through the gravity center of the screen box of the vibrating box. The utility model has the characteristics of good screen penetrating performance and high screening efficiency, and can be used for screening materials with larger viscosity, higher water content or more throughs.
Description
Technical field
The utility model belongs to the vibration screening machinery field, mainly relates to use the mode of vibration that amplitude successively decreases, the amplitude that the improves bolting efficient banana vibratory sieve that successively decreases.
Background technology
The banana-shaped vibratory sieve mainly is the compass screen surface that a following spill is arranged, and the compass screen surface of this vibratory sieve and the inclination angle of horizontal plane reduce from the feeding end to the discharge end gradually.Because the screen angle of feeding end is bigger,, can improve the disposal ability of vibratory sieve so the speed of service of material on compass screen surface accelerated.This is what relatively to be suitable for for more open material, and is moisture more if the viscosity of material is bigger, during stifled easily sieve, perhaps the screenings of material more for a long time, the screening effect of feeding end is just influenced.Also increase the screening burden of discharge end simultaneously, influenced the screening efficiency of vibratory sieve.
The utility model content
The purpose of this utility model provides a kind of amplitude banana vibratory sieve that successively decreases, and this vibratory sieve can effectively improve the screening effect of banana-shaped vibratory sieve screen box feeding end and the screening efficiency of vibratory sieve.
The utility model realizes that by following measure vibratory sieve mainly is made up of screen box, screen cloth, exciting device and frame etc., and screen box is installed on the frame by vibration absorber.It is characterized in that: a banana-shaped screen cloth is arranged, be installed in the screen box of vibratory sieve; Exciting device is made up of two vibrators, and a vibrator is arranged on the feeding end of screen box, and another vibrator is arranged on the discharge end of screen box; Distance between two vibrators screen box length 1/3rd to 5/6ths between; The eccentric mass difference of two vibrators, the eccentric mass of feeding end vibrator are greater than the eccentric mass of discharge end vibrator, and promptly the amplitude of screen box feeding end is greater than the amplitude of discharge end.The direction of rotation of two vibrators is opposite, and the position that vibration is made a concerted effort is by the center of gravity of vibratory sieve screen box.The exciting device of vibratory sieve is the vibrator of eccentric shaft type or eccentric block formula, and is provided with the eccentric mass adjusting device of additional eccentric block, adjusts the eccentric mass of vibrator by the mode that increases and decreases additional eccentric block.
During vibratory sieve work, two vibrators are respectively under the driving of two motor, with the speed rotation together of opposite direction.Because the eccentric mass difference of two vibrators, the eccentric mass of feeding end vibrator is bigger, so the amplitude of the feeding end of screen box is greater than the amplitude of screen box discharge end.Material on the compass screen surface passes through compass screen surface with the motion mode that amplitude successively decreases.
The beneficial effects of the utility model are, because the eccentric mass of this vibratory sieve feeding end vibrator is greater than the eccentric mass of discharge end vibrator, promptly the amplitude of screen box feeding end is greater than the amplitude of discharge end, and the trend that amplitude is formed successively decrease changes.Because the screen angle of feeding end is bigger, so accelerated the cloth of feeding end and the effect of screening.The amplitude of discharge end diminishes, and screen angle is also little, so that the saturating sieve effect of material obviously improve.Can be applicable to bigger, moisture more or the material screening that screenings is more of viscosity.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, and 1 is that screen box, 2 is that discharge end vibrator, 3 is that screen cloth, 4 is that support of motor, 5 is that feeding end vibrator, 6 is that frame, 7 is a vibration absorber among the figure; A is that feeding end, the B of screen box is the discharge end of screen box.
The specific embodiment
Below in conjunction with a description of drawings embodiment of the present utility model.Vibratory sieve mainly is made up of screen box 1, screen cloth 3, exciting device and frame 6 etc., and screen box 1 is installed on the frame 6 by vibration absorber 7, and the motor mounting of exciting device is on support of motor 4.Double-layer banana shape screen cloth 3 is installed in the screen box 1 of vibratory sieve; Exciting device is made up of two vibrators, and a vibrator 5 is arranged near the feeding end A of screen box, and another vibrator 2 is arranged near the discharge end B of screen box; The distance at two vibrator centers is 1/2nd of screen box 1 length; The eccentric mass difference of two vibrators, the eccentric mass of feeding end vibrator 5 are greater than the eccentric mass of discharge end vibrator 2, and the amplitude of screen box feeding end is 10mm, and the amplitude of discharge end is 8mm.The direction of rotation of two vibrators is opposite, and the position that vibration is made a concerted effort is by the center of gravity of vibratory sieve screen box 1.Two vibrators of vibratory sieve are eccentric block formula vibrators, and are provided with the eccentric mass adjusting device of additional eccentric block, can adjust the eccentric mass of vibrator by the mode that increases and decreases additional eccentric block.
