Description
Technical field
The utility model belongs to the vibration screening machinery field, mainly relates to the material screening operation of industries such as metallurgy, mine, chemical industry and building materials, can effectively improve the diaxon elliptical orbit combination vibration sieve of disposal ability and screening efficiency.
Background technology
Because the production scale of industries such as metallurgy, mine constantly develops, the demand of various large-scale vibrating screens is also increased year by year, and problems such as the structure heaviness of thereupon bringing, difficult in maintenance, manufacturing cost height are also given prominence to gradually.The difficulty of large-scale vibrating screen in processing and manufacturing and installation process is also bigger, has also restricted the sound development of large-scale vibrating screen in some aspects.The performance and the running parameter of an other vibratory sieve are more single, and the movement locus of material on compass screen surface is single, and especially in the screening operation of humidity or fine granular materials, the material plug-hole, screening percentage is low, treating capacity is little etc., and problem can not get effective solution.
Summary of the invention
The purpose of this utility model provides a kind of diaxon elliptical orbit combination vibration sieve, this vibratory sieve is formed by the vibratory sieve unit combination of a plurality of elliptical trajectories, have simple in structure, manufacturing and characteristics easy to maintenance, can improve the disposal ability and the screening efficiency of vibratory sieve effectively.
The utility model realizes that by following measure vibratory sieve mainly is made up of screen box, screen cloth, vibrating device, drive motors and vibration damping frame etc., it is characterized in that: whole screen(ing) machine is that the vibratory sieve unit combination by a plurality of elliptical trajectories forms; Each vibratory sieve unit all is installed on the frame by vibration absorber, is provided with independently screen box, screen cloth and vibrating device, and whole compass screen surface is overlapped successively from beginning to end by the compass screen surface of each vibratory sieve unit; The vibrating device of each vibratory sieve unit is mounted in the diaxon piece eccentric elliptic track vibrator on the screen box, and two vibrating shafts of vibrator are installed on the vibrator casing by bearing or are installed on the side plate of screen box, and eccentric block is installed in the two ends of vibrating shaft; The parameter meshed gears such as pass through between two vibrating shafts and connect, motor is connected with one of them vibrating shaft; The eccentric weight of eccentric block equates on two vibrating shafts, and eccentric direction is asymmetric, and the angle that the eccentric direction of one of them eccentric block departs from symmetric position is less than 90 degree greater than 0 degree.The concrete installation site of eccentric block is, when two vibrating shaft center line place planar horizontal, the eccentric direction of eccentric block is vertically downward the time on vibrating shaft, and the eccentric direction of eccentric block and first angle are α on another vibrating shaft, and the value of α is greater than 0 degree, less than 90 degree.Because the eccentric direction of two vibrator eccentric blocks is not in symmetric position, so the movement locus of vibratory sieve is oval, the eccentric direction that changes an eccentric block departs from the angle of symmetric position, just can change the ratio of the major axis and the minor axis of elliptical path.
The vibratory sieve unit of forming the elliptical trajectory of screen(ing) machine has 2-6.The angle that the eccentric direction of eccentric block departs from symmetric position on vibrating shaft in each vibratory sieve unit from the feeding end to the discharge end equates, increases progressively successively or successively decreases successively, makes the ellipse short shaft equal in length, the increasing or decreasing that form each vibratory sieve unit elliptic motion trace.
The oval-shaped movement locus of vibrator also can be used the mode that changes the eccentric block eccentric weight and realize, when the eccentric direction of eccentric block on two vibrating shafts is symmetrical, the eccentric weight of eccentric block is unequal on two vibrating shafts, change the poor of eccentric weight on two vibrating shafts, can change the ratio of the major axis and the minor axis of elliptical path.That the screen angle of each vibratory sieve unit is from the feeding end to the discharge end is equal, increase progressively successively or the mode of successively decreasing is successively arranged.The vibration frequency and the amplitude of each vibratory sieve unit vibrator can be adjusted.
The beneficial effects of the utility model are: because whole compass screen surface is to get compass screen surface by a plurality of vibratory sieves unit to combine, so reduced the ginseng of the equipment weight of shaking, reduced the dynamic load of equipment, avoided the generation of resonance, be convenient to the large scale development of vibratory sieve equipment.Simultaneously, the movement locus of each vibratory sieve unit can be different, can make the different material on the compass screen surface realize that layering is obvious, all even not plug-hole of thickness.Have the big and high characteristics of screening efficiency for the treatment of capacity, have broad application prospects and practicality widely.Can be applicable to the screening operation of every profession and trade material, be particularly suitable for the screening operation of moist fine granular materials.
