Including the frame seat, ann has screening plant on the frame seat, and screening plant one end is equipped with the pan feeding chute, and the other end is equipped with the chute, is equipped with the minus sieve chute below screening plant, screening plant includes many parallel arrangement's sieve axle, but sieve the epaxial tapered sieve piece that is equipped with axial that the multi -disc evenly arranged and adjusts, the epaxial tapered sieve piece of adjacent sieve alternates each other arranges and leaves even clearance, constitutes the sieve mesh, the latent adjustable tapered scraper of the formula of burying with tapered sieve piece matched with is all installed down to every sieve axle. The utility model discloses the dry screening of thick, particulate viscidity material design, field particulate viscidity materials such as specially adapted colliery, coal washery, firepower power plant, pier, metallurgy is specially blocked up, is run for the screening is moist, easy.
Description
Technical field
The utility model relates to particulate dry screening technical field, the fine particle classification screen that specifically one aims at and sieves humidity, easily blocks up, runs slightly, 1 ~ 20 particulate viscous material designs, is specially adapted to the dry screening of the field particulate viscous materials such as colliery, coal washery, firepower electrical plant, harbour, metallurgy.
Background technology
The dry screening of below 20mm particulate viscous material is ubiquitous technical barrier in current screening operation both at home and abroad.Because the table such as raw coal water content is large, humidity, particulate, viscous material are adhered to one another agglomerating, cause loose difficulty, easily stick on compass screen surface and block sieve aperture, the effective sifting area of compass screen surface is reduced, causes screening efficiency to decline, and material group is not loose, not stratified, mass motion, makes screening process be difficult to.So be the technical problem being badly in need of in current screening operation solving for the dry screening of below 20mm moist fine particulate viscous material.
Summary of the invention
The FAQs that the utility model occurs for domestic and international original particulate dry screening equipment, provides a kind of fine particle classification screen, solves putty when 1 ~ 20mm moist fine particulate viscous material sieves, runs the technical problems such as thick.
The utility model is by the following technical programs: a kind of fine particle classification screen, comprises frame seat; Described frame seat is provided with screening plant; Described screening plant one end is provided with pan feeding chute, and the other end is provided with discharging chute, is provided with chute under sieve below screening plant;
A kind of fine particle classification screen, comprises frame seat; Described frame seat is provided with screening plant; Described screening plant one end is provided with pan feeding chute, and the other end is provided with discharging chute, is provided with chute under sieve below screening plant;
Described screening plant comprises and is arranged on many between two bearings room, the left and right sieve axles be arranged in parallel; Described sieve axle is equipped with the tapered sieve be evenly arranged; Tapered sieve on described adjacent sieve axle intert arrange, leave uniform gap each other, composition sieve aperture;
The adjustable tapered scraper of the embedded matched with tapered sieve is installed under described each sieve axle.
It is further: described tapered sieve is connected by key with sieve axle; The structure of described tapered sieve is that tooth root is thick, crown thin, and monoblock cast forms.
Described sieve axle is provided with pad between each tapered sieve.
Described sieve axle two ends are respectively provided with a bearing chamber, and sieve axle is arranged on bearing chamber by bearing; Sieve axle connects gear-box by shaft coupling; Described gear-box connects driving mechanism.
The utility model principle utilizes single driving mechanism to drive the single of rotating in same direction or many sieve axles, sieve axle is equipped with some tapered sieves, tapered sieve on adjacent sieve axle is interspersed arranges composition sieve aperture, the material being less than sieve aperture in operation process sieves thoroughly, and the material rolls forward in sieve being greater than sieve aperture is discharged from discharging chute.
Technological merit of the present utility model is: on sieve axle, install multiple tapered sieve by key, tapered sieve design feature is that tooth root is thick, crown is thin, intensity is large, namely monoblock cast avoids after sieve is welded with axle sleeve and snap the distortion caused, it is produce slip repeatedly circumferentially between sieve and sieve axle and radially wobble that sieve snaps the consequence caused, radially wobble once produce, produce occlusion wearing and tearing between adjacent sieve and wait major accident; Tapered sieve on adjacent sieve axle is interted and is arranged and form sieve aperture, and this sieve aperture is specially for fine screening, and can solve material and run the problems such as thick; Tapered sieve can axial adjustment by pad on sieve axle, and object is to adapt to different gradings, flexible and changeable, strong adaptability; The adjustable tapered scraper of embedded is installed respectively below each sieve axle, the twister be bonded in sieve and bur can be rooted out, to keep sieve aperture unobstructed.
