Description

A kind of linear motion separating sieve
Technical field
The present invention relates to a kind of linear motion separating sieves, belong to separating sieve device field.
Background technology
Vibrating screen is vibrated using reciprocating rotary type caused by oscillator exciting and worked.The upper rotation weight of oscillator makes sieve Face generates plane whirling vibration, and lower rotation weight then makes compass screen surface generate conical surface rotary vibration, and the effect of synergy then makes Compass screen surface generates again rotation type and vibrates.Its oscillation trajectory is a complicated space curve.The curve is projected as a circle in horizontal plane, and On the vertical plane be projected as one ellipse.Adjust the exciting force of upper and lower rotation weight, thus it is possible to vary amplitude.And it adjusts upper and lower The space phase angle of weight can then change the curve shape of compass screen surface movement locus and change the movement locus of material on compass screen surface. There are the defects of cloth is uneven, breakneck acceleration is slow, and exciting force is weak, vibrating noise is big, energy consumption is larger for existing vibrating screen.
The content of the invention
The goal of the invention of the present invention is：In view of the above problems, a kind of linear motion separating sieve, structure are provided Rationally, exciting force is strong, vibrating noise is small, screening efficiency is high, treating capacity is big, for ease of maintenaince, long lifespan.
The technical solution adopted by the present invention is as follows：
A kind of linear motion separating sieve, which is characterized in that including screen frame (unit), sifting bed and elastic component, sifting bed passes through elastic component tilting rack It is located on screen frame (unit), the outlet of sifting bed is downward；Sifting bed includes bed body, sieve and vibrator, and sieve splits bed body above and below inclined Two layers, vibrator is fixed in bed body, which makes sifting bed make periodical straight-line oscillation by wobbler action.The exciting utensil There is wobbler action, said structure can be using the weight of material itself, and material rolls in screening process from upper material channel, Thin material, into his passage of lower material, and is collected after sieve screens in lower material channel end, and thick material is in upper material End is collected, and the inclined structure of the sifting bed can collect material rolling, and material is avoided locally to collect, and can improve screening speed Degree and screening progress, meanwhile, it is energy-saving using the realization of material self gravitation, it can effectively realize the straight-line transmitting of material on sieve It is defeated.
Further, sifting bed angle of inclination in the horizontal direction is 5-30 degree.The angle of inclination is ensureing material rolling Meanwhile ensure the screening quality of sieve, the breakneck acceleration of sieve is improved, material self gravitation is made full use of to realize energy-saving.
Further, vibrator is arranged above sieve, and sieve leads to two layers of respectively upper material up and down that bed body is formed Road and lower material channel.
Further, sieve has at least two screening areas, and the angle of inclination of two screening areas gradually subtracts along screening direction It is small.The design of the screening area can be realized screens twice, first carry out roughing, then carries out selected, the most particulate thing of roughing It after material, is screened again at selected end, improves screening precision；Compass screen surface is made of multistage angle, and feed end Flow of Goods and Materials speed is fast, goes out Expect that end Flow of Goods and Materials speed is slow, the material of feed end is layered rapidly, and coarse fodder floats, and fines sinks, and screening efficiency is commonly to sieve .- times.The vibrating screen of the structure is particularly suitable for the material that undersize material content is high in processing feed.
Further, sifting bed includes crossbeam and several plate bodys are spliced, and stitching portion is connected by screw bolts, on sieve nest Reinforcing plate is provided with screen frame (unit) junction or strengthens angle steel.Complete machine makes complete machine load as far as possible in the case where ensureing its intensity It is small.Meanwhile the high strength exploitation that self-locking performance is high, stability is strong is used with side plate after crossbeam stress relief annealing, effectively avoid The extra duty that welding stress is brought improves fatigue life of complete machine；To be effectively increased the intensity of side plate.All companies of sifting bed It meets place to be connected with high strength steel structural bolts, the stress generated to avoid welding.Crossbeam be seamless hollow rectangular tube, rigidity Greatly, it is light-weight.Crossbeam design fully reserves enough safety coefficients to adapt to unpredictable adverse circumstances.On sieve crossbeam Abrasive rubber backplate is installed, resistance to erosion is wear-resistant, and backplate is installed using gluing fastener-type structure, replaces simple and convenient.Screen frame (unit) For bolt assembling structure, transport is more convenient, need to only be assembled each component to scene upper.
Further, vibrator is driven using motor；Motor is connected with vibrator by yielding coupling, the driving of motor Circuit has reversing braking；Vibrating screen is enable safely and smoothly to realize shutdown, sifting bed is enable quickly to jump over resonance region, extends it Whole service life.
Further, more than two vibrators are provided on sifting bed, are connected between adjacent vibrator using transmission shaft.Exciting Power can adjust according to screening materials carrying size, ensure that material contacts on compass screen surface with screen slot to greatest extent；Make compass screen surface block can Energy property minimizes.
Further, transmission shaft drives vibrator by gear, and two vibrators are removably symmetrically mounted on sifting bed On crossbeam.Driven side gear formula service life is longer, and thin oil lubricant is lower by temperature.
Further, sieve includes two kinds of structures of modular and presser type, and module type screen mesh is installed to sieve for clamping On bed.Spliced structure does not have any weld seam, largely avoids the cracking of side plate, using self-locking performance height, stability Strong high strength exploitation effectively prevents the extra duty that welding stress is brought, and improves the fatigue life of complete machine.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. compass screen surface is made of multistage angle, feed end Flow of Goods and Materials speed is fast, and discharge end Flow of Goods and Materials speed is slow, feed end Material is layered rapidly, and coarse fodder floats, and fines sinks, and screening efficiency is 1.5-2 times commonly sieved.The vibrating screen of the structure is especially The high material of undersize material content suitable for processing feed；
2. material rolls in screening process from upper material channel, thin material after sieve screens into his passage of lower material, And be collected in lower material channel end, thick material is collected in upper material end, and the inclined structure of the sifting bed can make material Rolling is collected, and material is avoided locally to collect, can improve breakneck acceleration and screening progress, meanwhile, it is real using material self gravitation It is existing energy-saving, it can effectively realize the linear transmission of material on sieve.
