Technical field
The utility model belongs to the vibration screening machinery field, relate generally to industries such as technics of metallurgy mineral dressing, coal separation, chemical fertilizer, building materials, chemical industry, thin or granular material is done, the high frequency elliptical vibration dusting cover of wet classification, dehydration, de-mediated operation to having in more liquid.
Background technology
At present " high frequency vibrating fine screen " used is by motor drives piece eccentric type vibrator or vibrating motor work, drives the vibration of multilayer screen box, realizes having in more liquid thin or granular material is done, the wet separation operation.The vibrating device that this vibratory sieve is used is made up of 1-2 group vibrator or vibrating motor, is positioned at the top of sieve nest, is installed on the screen box of upper strata, and the movement locus of vibratory sieve is circular motion track or straight-line trajectory.Because tiny powdered material particularly has certain viscosity between the particle of wet type powder material, adopt the sieving technology of straight-line trajectory or circular motion track merely, often the effect of its screen-penetrating performance and screening is all not ideal enough.
The utility model content
The purpose of this utility model provides a kind of high frequency elliptical vibration dusting cover, and vibration frequency can reach 50Hz, and the screen-penetrating performance of this high frequency elliptical vibration dusting cover is better, when improving screening efficiency, can prolong the service life of screen cloth, increases the production capacity of system effectively.
The utility model realizes that by following measure vibratory sieve mainly is made up of frame, sieve nest, shear spring, distributing device, discharge system and vibrating device etc.Sieve nest is the screen box that is provided with by last lower leaf, from the bottom to top, shifts to install to discharge end successively, forms by tie-beam is fixing; Fixedly the tie-beam of screen box is connected with carrier bar on the frame by the shear spring system.Feeding end at every layer of screen box is provided with a distributing device, and distributing device mainly is made up of material inlet, dashpot and material outlet; The length of distributing device and material outlet all less than the width of screen box, is distributed to material to be sieved on the compass screen surface equably, realizes screening; At the exhaust end of sieve nest, be provided with the discharge guide plate and the discharge funnel that are fixed on the frame, discharge guide plate and discharge funnel have two groups, and the oversize discharge guide plate of each screen box is connected with oversize discharge funnel; The discharge guide plate of minus mesh is connected with minus mesh discharge funnel, respectively each layer oversize and minus mesh centralized collection is discharged.It is characterized in that: the vibrator that described vibrating device is made up of the eccentric vibrating shafts of two pieces, be installed in the top of sieve nest, the vibrating shaft of vibrator is installed in by bearing on the casing of vibrator, 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, during the eccentric direction level of eccentric block, the eccentric direction of eccentric block and first angle are α on another vibrating shaft on vibrating shaft, and the value of α is greater than 0 degree, less than 90 degree.
Because the eccentric direction of two vibrating shaft 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 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.
Each screen box mainly is made up of side plate, screen cloth and base plate, and the two ends of screen cloth are fixed on the feeding end and the discharge end of screen box, and the edge is positioned on the holder net angle steel of sieve box side plate inboard, fixes by screen cloth tensioning plate and tensioning bolt; The screen box base plate be positioned at screen cloth below, accept undersize material, minus mesh is moved to exhaust end.Screen box has 5～25 ° mounted angle, and material is flowed forward along the inclination angle.For weight reduction, increase the service life, screen cloth adopts polyurethane material to make.
The quantity of screen box can be 1-5 on the sieve nest, and stack is provided with up and down, forms a multichannel feeding sieve nest, and by the vibrator driving of elliptical trajectory, the multilayer compass screen surface is worked simultaneously.Can reduce the quantity of system's production line, reduce construction costs, less maintenance load.
Because what this vibratory sieve adopted is the structure of small size and multilayer, the screen cloth of polyurethane material has compact conformation and light characteristics, and vibration frequency can be brought up to the high-frequency of 50Hz.
The beneficial effects of the utility model are: use the eccentric vibrating shafts of two pieces, the parameter meshed gears such as pass through and connect a Motor Drive.Because the eccentric direction of two vibrating shaft 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.When improving screen-penetrating performance, improved the screening efficiency of vibratory sieve effectively.Has working stability, characteristics such as noise is little, low in energy consumption, compass screen surface long service life; Multi-deck screen space of planes stack combinations can enlarge system's production capacity.Be applicable in technics of metallurgy mineral dressing, coal separation, chemical fertilizer, building materials, chemical industry and the various mineral deep-processing process, thin or granular material is done, the wet separation operation to having in more liquid.
