Description
Technical field
This utility model belongs to Supplying Sieving Mechanism technical field, more particularly, it relates to a kind of material screening scraper plate
Formula rotary screen.
Background technology
The metal powder materials such as metallurgic auxiliary materials, as the auxiliary product in steel-making, are requisite in metallurgy industry steelmaking process
Additive, it has large effect for the final effect smelted.And metal powder material is before the use, it usually needs use and divide
Optional equipment sieves, so that its granularity disclosure satisfy that use requirement, produces dust from flying, pollute building ring when preventing from using
Border.In prior art, the separation of same material variable grain mainly uses Multilayer vibrating screen and rotary screen subset, wherein, rolling
Shaft screen screening is primarily adapted for use in granule in same material and separates with powder.
Existing rotary screen generally uses buncher to slow down through reductor, is then driven by belt or chain drive
Drive axis on rotary screen, and then drive rotary screen to run.Material relies on deadweight to discharging opening from the feeding mouth of rotary screen
Motion, and rely on the sieve aperture rotated on cylinder that material is sieved.Its material screening mainly has conjunction by control rotary screen
Suitable rotating speed, thus material web is played rotary screen top, fall in freely falling body mode, it is achieved material particles and the sieve of powder
Point.The screening effect of material is affected the biggest by drum rotation speed, and rotating speed is too small, and material cannot be taken up rotary screen top；
Rotating speed is excessive, and because of effect of inertia, material can rotate together along with rotary screen, thus affects screening efficiency and yield.Meanwhile, cylinder
The inventory entered in sieve is too much, volume of material density is excessive, moisture is crossed metropolis and caused and material web cannot be played rolling
Shaft screen top, thus affect screening efficiency.Therefore, conventional rollers sieve is high to the rotation speed requirements of rotary screen design, is generally difficult to
