Abstract
The utility model relates to a double-material independent-supported double-driven tension-relaxation sieve, which is designed in order to enhance the service life of the existing tension-relaxation sieve. An inner and an outer sieve boxes which are sheathed together are driven by a drive mechanism of an elastic connecting rod with double crank of both sides, so that flexible sieve nets which are arranged on the cross beams of the inner and the outer sieve boxes generate tension-relaxation sieving movement. An elastic supporting board of a sieve machine is a super strong glass fibre board with large grids, and an elastic connecting rod board is a longitudinal unidirectional glass fibre board. The material feeding end of the inner sieve box is provided with a material buffer plate, so the service life of the sieve machine is enhanced. The utility model can be used for sieving materials of the metallurgy industry, the mine industry, the construction material industry, the urban refuse industry, the sewage purification industry, etc.
Description
The utility model belongs in the industrial and mining enterprises, and being used for dry type screening, to contain mud, water or powder more, the two driving of two plastid independent support of the difficult screened material that viscosity is bigger flip flop screens.
Flip flop screen is by the stretched and relaxed motion of Flexible sieve, makes material under the effect of screen cloth amplitude and elastic force, contacts wire side continuously, upsprings loose and falls motions such as sieve, finishes screening operation.Because flip flop screen is a screen box inside and outside supporting, lead by elastic supporting plate, by shaft joint and crank elastic link transferring power, so the performance of the elastic link plate of common elastic supporting plate and crank elastic link will directly influence the life-span of vibratory sieve.The material of existing flip flop screen material feeding end is directly fallen on the compass screen surface, and the impulsive force that the material drop forms is all born by Flexible sieve, and the life-span of material feeding end place screen cloth is shortened greatly.
But the purpose of this utility model is the bigger difficult screened material of dry type screening viscosity that designs at the deficiencies in the prior art, and can improve the two flip flop screens that drive of two plastid independent support of screen(ing) machine bulk life time.
The utility model is realized by following measure.Flip flop screen is made up of support, underframe, inside and outside screen box, Flexible sieve, support unit, transmission mechanism and isolation spring, it is characterized in that: the inside and outside screen box that is sleeved on together is connected with underframe by array macrolattice Superstrength glass fibrous elasticity plate support unit respectively; The interlaced setting of crossbeam at the inside and outside screen box sieve end, its upper surface is at grade; Several pieces Flexible sieves are installed in respectively on the inside and outside screen box crossbeam successively, and on the screen box crossbeam, opposite side was fixed on the crossbeam of outer screen box in a side was fixed on; Feeding end at interior screen box is provided with the material buffer plate.For preventing that material from leaking down from screen cloth and interpleural slit, at the intersection of interior sieve box side plate and Flexible sieve, be provided with the lateral seal plate, bottom position when the lower edge of sealing plate is lower than screen cloth and relaxes.Bilateral double-crank elastic link transmission mechanism is arranged on the material feeding end of underframe, and one-way glass fibrous elasticity link rod plate is connected with the material feeding end of inside and outside screen box respectively.The elastic vibration isolation device of forming by rubber spring between underframe and the support.
Bilateral double-crank elastic link transmission mechanism is made up of two groups of eccentric shafts that are the eccentric throw such as two-way of 180 ° of settings, the two eccentric diameters of axle of a direction are connected with interior screen box by the elastic link plate of elastic link, and the two eccentric diameters of axle of another direction are connected with outer screen box by the elastic link plate of elastic link.Connect by the little pendulum connecting axle of rigidity in the middle of two groups of eccentric shafts, and be connected with motor by belt pulley.The little pendulum connecting axle of rigidity is made up of two groups of diaphragm shaft joints, and several pieces elasticity of diaphragm shaft joint connect diaphragm, are connected with connected two bosses respectively by connecting bolt.Elastic supporting plate is made up of macrolattice Superstrength glass fibrous elasticity plate.The elastic link plate is the reinforcing glass fiberboard of vertical folk prescription to arrangement, and according to the size of screen(ing) machine, each connects the elastic link plate of eccentric shaft and screen box and can be made up of side by side the 1-3 group.The installing hole of Flexible sieve according to the screening needs of different material, is selected the screen cloth of different pitch-rows apart from being adjustable, makes screen cloth can keep the state of Zhang Ping or stretching when work.
During flip flop screen work, motor drives the motion of bilateral double-crank elastic link transmission mechanism by belt pulley, and 180 ° two groups of eccentric shafts drive inside and outside screen box by elastic link and make rightabout linear reciprocating motion each other.The inside and outside screen box crossbeam of interlaced arrangement drives Flexible sieve and alternately does tension and relaxation motion lax and upwards Zhang Ping downwards.Material is fallen on the Flexible sieve along the screen(ing) machine inclination angle after slowing down the impact energy that is produced by high potential difference through buffer board, by upspring, program loose and saturating sieve finishes the classification to material.Because the force direction that is subjected to of elastic link plate is single, with tension and compression be bent into the master.So adopting vertical folk prescription is tangible to glass mat to the effect that improves its service life.
Be with the little pendulum connecting axle of rigidity of diaphragm shaft joint, connect the double-crank eccentric shaft of both sides synchronously, make it to do coaxial, synchronous noiselessness motion, guarantee synchronous push pull maneuver, prevented the fracture of connecting axle effectively inside and outside screen box both sides.
By the screen cloth of different pitch-rows is installed, can make screen cloth when tensioning, produce different tensile elongations.Can producing on the one hand jumps plays the acceleration of material, and the screen cloth of La Changing becomes big by the trace of mesh on the other hand, can prevent the generation of plug-hole phenomenon, improves the screening effect to high-viscosity material.
The utility model has the advantages that, adopted biserial double-crank elastic link transmission mechanism, unidirectional fibre elastic link plate, macrolattice fibrous elasticity gripper shoe, diaphragm shaft joint, high-performance tension and relaxation screen cloth and buffer board has been set, flip flop screen has been had operate steadily, characteristics such as the life-span is long, screening efficiency is high and production capacity is big at material feeding end.The material screening that can be widely used in industries such as metallurgy, mine, coal, building materials, water power, municipal refuse and sewage purification.
Fig. 1 is a structural representation of the present utility model, and (1) is that support, (2) are support inclination angle for interior screen box support unit, (14) outer screen box support unit, (15) for discharging opening, α for outer screen box, (13) for interior screen box, (12) for outer screen box crossbeam, (11) for interior screen box crossbeam, (10) for Flexible sieve, (9) for buffer board, (8) for elastic supporting plate, (7) for the elastic link plate of elastic link, (6) for transmission mechanism, (5) for underframe, (4) for rubber spring, (3) among the figure.
Fig. 2 is the cutaway view of Fig. 1, and the left side is that A-A cutaway view, right side are the B-B cutaway view, and (16) are the lateral seal plate among the figure, and all the other labels are identical with Fig. 1.
Fig. 3 is the Flexible sieve working state figure, and (8) are that Flexible sieve, (9) are outer screen box crossbeam for interior screen box crossbeam, (10) among the figure, and arrow is the materials flow direction, and a, c are for alternately straining relaxed state, and b is a poised state.
