Description
Technical field
The utility model relates to material screening technical field, specifically a kind of sieve plate for preventing material sticks and use the sieve
The vibrating screen of plate.
Background technique
Wet glutinous material is sieved at present, it is general in the screening link especially sieved under the blast furnace of steel mill's iron-smelter
Store-through the problem of exactly wet glutinous material can be adhered on sieve plate, to cause compass screen surface material hardened, block sieve pore, influence to sieve
Efficiency.
Common vibrating screen is broadly divided into compass screen surface fixed and two kinds of compass screen surface float type, and there is presently no very for fixed compass screen surface
It is hardened that good method thoroughly solves the problems, such as that wet glutinous material is adhered in compass screen surface；Floating screening surface can solve this problem, but it exists
Sieve nest occupied space is big, and unit area treating capacity is low, and structure is complicated for sieve nest, difficult in maintenance, the problem of screen size control difference.
Grate size mine screen master sieve plate to be used has following a few classes under slot at present:
One, bar screen, sieve plate are made of rod iron placed side by side, and rod iron one end is fixed on frame, and the other end is cantilever
Structure, at work, since the vibration of vibrating screen is when being transmitted on rod iron, the vibration on rod iron is returned with rod iron jib-length
Lengthening, vibration also can be more violent；
The defect of this sieve plate is: weak to the control of screening materials carrying granularity, race is thick serious under sieving, in addition, wet glutinous material meeting
Start to bond in the root that rod iron is connect with frame, thus will affect the oscillation intensity of rod iron, it is hardened to be sent out by root rapidly
Whole compass screen surfaces are opened up, sieve cover cleaning is difficult；
Two, polyurethane floating sieve plate, sieve plate are made of sheet of polyurethane, without structural support in sieve plate, the one of sieve plate
While being mounted on fixed cross beam, another side is mounted on floating crossbeam, by the vibration of screen(ing) machine drive floating beam mobile from
And the sieve plate being mounted between fixed beam and floating beam is made to form the state for speeding to open, to achieve the effect that compass screen surface vibrates；
The defect of this sieve plate is: although this sieve plate due to generating the drastic deformation of compass screen surface when speeding, and makes material
It can not adhere in compass screen surface, but the problem of this structure maximum is that compass screen surface angle requirement is larger, is generally greater than 25 °, screen length
It is required that it is larger, so occupied space is larger.In addition, compass screen surface amplitude is big when processing material is few, material bounce acutely, connects with compass screen surface
Touching number is few, and screening efficiency is low, and when processing material is more, floating beam floating plate output and amount of floating can be all greatly affected, this
When on-the-sieve material bouncing effect significantly reduce, the bed of material be difficult sieve thoroughly, and under slot sieve processing material be discontinuity feed, one-time feeding
Only tens seconds time, material can be few how few quickly excessive to material again to expecting from material, so, sieve of this compass screen surface to material
Divide effect bad.
Summary of the invention

2, compass screen surface uses thin compass screen surface, and elasticity is good；Wherein, compass screen surface is separated with the supporting rib on sieve nest, in vibrating screen work,
Compass screen surface impact related to supporting rib, it is therefore prevented that adherency of the wet glutinous material on compass screen surface；
3, due to the structure that sieve plate is connected using splicing, material attachment is had at the connecting sewing of splicing, thus to entire sieve
Face diffusion；Therefore, extended outwardly using compass screen surface, the extension to extend out covers the seam crossing of two sieve plate joints；Because
The compass screen surface to extend out be not it is fixed, can float up and down in company with shaker vibration, to avoid the attachment of the wet glutinous material of object,
Seam is just not present in vibrating screen entire in this way, and without the region of wet glutinous material attachment, the adherency in compass screen surface for solving material is asked
Topic；
4, the partial region setting between compass screen surface and sieve nest separates place, improves compass screen surface and the vibration effect of its extension
Fruit reduces the material sticks of compass screen surface.
