Description

A kind of adjustable multi-layer precise vibration screening device

Technical field

The invention belongs to sieving machine fields, are related to a kind of adjustable multi-layer precise vibration screening device.

Background technology

At present, sieving machine is widely used in multiple industries such as coal, metallurgy, mine, chemical industry, food, current sieve The relative motion of industry equipment utilization bulk granular material and compass screen surface is allocated as, makes partial particulate through sieve pore, by objects such as sand, gravel, rubbles Material is divided into the vibration screening machinery equipment of different stage by granular size.The particle rank of screening depends on compass screen surface, and compass screen surface point is combed Three kinds of grid, screen and mesh screen.Comb grid are suitable for screening large granular materials, and comb grid gap is 1.1~1.2 times of screenings grain size, It is not preferably less than 50 millimeters generally.Screen is formed by steel plate punching, and hole is rounded, rectangular or rectangle, and aperture is generally 10~80 millis Rice, service life is longer, is not easy to plug, suitable for sieving medium grain.Mesh screen is weaved into or is welded by steel wire, and hole is square, square The advantages of shape or strip, common aperture are generally 6~85 millimeters, and strip sieve pore is suitable for the moist material of screening, mesh screen It is that effective area is larger.Screening machine principle is divided into, and rolls screening and vibrosieve.Drum screen point includes screen axis formula screening machine, rolling Shaft screen, solid, spiral roller picker, vane type roller picker etc., vibrosieve have banana screen, high clothes sieve, relaxation sieve etc. substantially.

And the principle of general granule materials screening is：Particle passes through from sieve plate, encounters sieve pore, and particle size is less than sieve pore Material sieve pore is passed through to become screenings, the particle that size is more than sieve pore does not pass through sieve pore as oversize.Wherein vibrating screen by In screen box vibration strongly, the phenomenon that reducing feed blocking sieve pore, make sieve that there is higher screening efficiency and productivity.

Mainstream screening plant currently on the market is mostly based on vibrating screen, supplemented by gravity flow screen；But just occur at present Vibrating screen for, vibration efficiency still has larger room for promotion, it is therefore necessary to which invention is a kind of to have reliable and stable, consumption Less, a kind of adjustable multi-layer precise vibration screening device for the advantages that low noise, long lifespan, the vibration shape are steady, screening efficiency is high.
