Description

Lump coal breaking system
Technical field
It the utility model is related to a kind of coal mining equipment, and in particular to a kind of sorting of lump coal and breaker composition Lump coal breaking system.
Background technology
The unearthed colliery in mine is required to crush it, is colliery granule fines by its fragmentation before transport utilizes After transported and shaped utilization, preferably have impact breaker and hammer to colliery product crushing effect in existing disintegrating machine Formula disintegrating machine, it is mainly crushed using shock power, applied widely, and crushing members abrasion is small, and replacing is convenient, compared with Usually applicable knife breaks to crush formula disintegrating machine with double roller and compare to have advantage very much, but it has one for the particle diameter for putting into raw material Provisioning request, after being unearthed, most of is overall block structure in colliery, when carrying out broken using above-mentioned disintegrating machine, is generally required Pounded in advance hit processing be fritter raw material, waste the substantial amounts of time;Hammer mill is used as broken equipment in one kind, after it is broken Material particular diameter it is larger, also need to carry out finished product again sometimes it is in small, broken bits, it is very troublesome, in addition, raw material is after input, to be tiny The mixture of particle and raw material block, substantial amounts of fine particle need to be fallen by castor bar put into together after, now be easily caused Solid accumulation at castor bar, not only influences the crushing effect of lump material, while also easily causes the blocking of castor bar, therefore actually broken Before, often advance with screen cloth and compound is subjected to screening separation, the material block side input of bulk carries out coarse crushing, whole process Practical operation is very troublesome.
Exist in the prior art and the broken patent of gradation sizing is largely carried out to lump coal, its principal mode is all first to use Hammer is broken or jaw crusher carries out one-level and crushed, and then carries out two-stage crushing by kibbler roll.One-level is broken and two level is broken Material is sieved by screening plant between broken, the input kibbler roll that particle is unsatisfactory for requiring is crushed, Grain meets that what is required is directly sent at finished product.This mode, extremely complex for a set of equipment, especially moving component, Two sets of disintegrating machines, maintenance cost are very high.Also equipment purchase cost can be significantly increased.
In addition, lump coal, before disintegrating apparatus is entered, pre-screening is highly desirable, and the repetition that can reduce qualified material is broken It is broken, energy consumption is reduced, it is too small to be also prevented from lump coal particle, the problem of dust emission is big occurs.But existing pre-screening is sieved through sieve, It is very easy to block sieve aperture, causes follow-up work efficiency to decline or directly shut down.But in existing technology, do not clear up effectively The device of screen cloth, reciprocating sieve pair has preferable effect with cohesive particle, but the particle for being stuck in sieve aperture can not be removed, Use for a long time, the work efficiency drop of whole system can be made.But screen cloth is changed to be required for shutting down substantially, it is very troublesome.
The content of the invention
The purpose of this utility model is, there is provided one kind can pre-screening will not putty, and only a set of disintegrating apparatus Lump coal breaking system.
To achieve these goals, the utility model includes, a pre-sifted separating device and a breaker, the pre-sifted Separating device includes a casing, and casing top is provided with a back taper hopper, and a combination rotating shaft is fixed in casing, and combination turns Axle includes an interior axle and an outer shaft, and interior axle is coaxial with outer shaft, and the interior axle passes through the fix bar at both ends and one the Two grate plates are fixedly connected, and first grate plate is fixed in the outer surface of the outer shaft, and the first grate plate and the second grate plate are provided with flat Row and uniformly the comb tooth of branch, the spacing being smaller than between the comb tooth of the first grate plate of the comb tooth of second grate plate;
