Description
Technical field
The utility model belongs to the vibration screening machinery field, and mainly relating to dry type screening, to contain mud, water or powder more, the large-scale flip flop screen of the sticking difficult screened material that looses of fine granularity.
Background technology
Moisture in the fine granularity material more for a long time, material very easily sticks on the compass screen surface, the screening efficiency of general vibratory sieve is significantly reduced, even influence ordinary production.Flip flop screen is by the stretched and relaxed motion of Flexible sieve, make material under the effect of screen cloth amplitude and elastic force, contact wire side continuously, upspring loose and fall motion such as sieve, finish the efficient screening of dry type of the bigger difficult screened material of viscosity and the operation of high productive capacity.The inside and outside screen box of existing flip flop screen is done rightabout reciprocating motion simultaneously, and its supporting arrangement and transmission mechanism be more complicated all, thus the fault rate of flip flop screen than higher, the stability of whole screen(ing) machine is also bad.
Summary of the invention
The purpose of this utility model provides a kind of large-scale flip flop screen, but this flip flop screen dry type is sieved the bigger difficult screened material of viscosity, and can improve the stability and the bulk life time of vibratory sieve greatly.
The technical solution adopted in the utility model is, large-scale flip flop screen mainly is made up of underframe, interior screen box, outer screen box, resilient suspension, elastic bearing, Flexible sieve, vibrating device and motor, it is characterized in that: interior screen box is connected with underframe by many group elastic bearings, is sleeved in the outer screen box; Outer screen box is lifted on the interior screen box by many groups resilient suspension; The inside and outside screen box crossbeam of the installation Flexible sieve of inside and outside screen box below is crisscross arranged, and its upper surface at grade; The multi-disc Flexible sieve is installed in to material feeding end on the screen box crossbeam of inside and outside screen box successively from the discharge end of screen box, and on the screen box crossbeam, opposite side was fixed on the outer screen box crossbeam in a side of screen cloth was fixed on, and adjacent screen mesh is overlapping setting on the screen box crossbeam.Vibrating device is the circular vibration device of band crank elastic link, and the vibrating shaft of circular vibration device is an eccentric shaft, is installed in by bearing block on the mounting rail of interior screen box material feeding end; The two ends of eccentric shaft are provided with the rotor journal that elastic link is installed, and an end of two elastic links is installed on the rotor journal by bearing, and the other end is connected with the connecting rod base of outer screen box material feeding end.The eccentric shaft of circular vibration device is connected with motor by belt pulley; Motor mounting is on the underframe of vibratory sieve.
For strengthening the rigidity of super wide inside and outside screen box crossbeam, screen box longeron and outer screen box longeron in installing respectively below inside and outside screen box crossbeam are formed interior screen box crossbeam group and outer screen box crossbeam group; For adapting to the screening demand of different viscosities material, the installing hole of Flexible sieve is apart from adjusting.To the impact of screen cloth, be provided with feed box when preventing that material from falling at the feeding end of interior screen box.
When large-scale flip flop screen is worked, motor produces exciting force by the eccentric shaft that belt transmits torque drive circular vibration device, make inside and outside screen box material feeding end do circular vibration, drive the both sides rotor journal simultaneously and make the elastic link motion, elastic link drives outer screen box and does reciprocal approximate straight line motion.The inside and outside screen box crossbeam group of interlaced arrangement drives the multi-disc Flexible sieve and alternately does tension and relaxation motion lax and upwards Zhang Ping downwards.Material on screen cloth by upspring, the program of loose and saturating sieve realizes graded operation.
By adjustment to screen cloth installing hole distance, can make screen cloth when tensioning, produce different tensile elongations, not only can producing jumps plays the different acceleration of material, can also make the screen cloth of elongation, trace by mesh changes, prevent the generation of plug-hole phenomenon, improve screening effect high-viscosity material.
The utility model has the advantages that, adopted band crank elastic link circular vibration device, elastic bearing, resilient suspension, can adjust structures such as pitch-row Flexible sieve and feed box, make the flip flop screen material feeding end have circular vibration; The inside and outside screen box crossbeam group Zhang Yundong that speeds has the feed box springing cloth that is uniformly dispersed, characteristics such as the Flexible sieve life-span is long, screening efficiency is high and production capacity is big.Solved the classification of the sticking material that looses of 3-6mm fine granularity, the super 2200mm of compass screen surface width reaches the high productive capacity of 3500mm.The material that can be widely used in industries such as coal 3-6mm thermal coal, mine, building materials, municipal refuse and sewage primary purifying efficiently sieves.
