Description
Technical field
The present invention relates to a kind of boiler plant technical field, particularly relate to a kind of steam coal block breaker.
Background technology
The fuel of current boiler is generally coal, but the thermal efficiency of the coal cinder that directly burns is lower, therefore, people first by coal breaker by coal crusher, and then the coal of powdery is used for boiler combustion, although this mode improves the thermal efficiency of coal, but the coal breaker of prior art and boiler plant are all independently equipment, therefore adopt comparatively loaded down with trivial details in this way, first coal cinder is needed to be transported in coal breaker, and then the coal of powdery is transported in boiler, length consuming time, working strength is larger, thus cause the time, the cost of manpower drops into larger, and the coal breaker of prior art generally adopts quartering hammer or broken wheel to carry out primary fragmentation, fragmentation may be there is not thorough, be difficult to edge coal and carry out broken phenomenon, thus cause coal particles size uneven, coal cinder may be wrapped in the coal of even powdery, the thermal efficiency of coal can be reduced like this.
Therefore, in order to solve above-mentioned Problems existing, the present invention spy provides a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide and a kind ofly can carry out fragmentation, crushing effect is desirable and cost is low a kind of steam coal block breaker by edge coal cinder.
The present invention is directed to the technical scheme that above-mentioned technological deficiency adopts is:
A kind of steam coal block breaker, comprise housing, described housing is cylinder, be divided into, in, lower three cavitys, respectively be one-level crushing chamber, two-stage crushing room and coal storeroom, a support has been horizontally disposed with in described one-level crushing chamber, described support is provided with compression roller mechanism, housing corresponding directly over described compression roller mechanism is provided with charging aperture, described two-stage crushing chamber internal surface is provided with a circle raceway, described raceway is provided with rotation breaker assembly, described two-stage crushing room and coal storeroom junction are provided with vibrations metal sieve plate, described coal storeroom side is provided with discharging connector, described discharging connector connects the charging connector of boiler.
The further setting of the present invention is: described compression roller mechanism comprises bearing block a, b and roll shaft a, b, and bearing block a, b connect roll shaft a, b respectively by bearing, and described roll shaft a connects initiative compression roller, and described roll shaft b connects driven rollers.
Adopt technique scheme, drive unit drives driven rollers to drive initiative compression roller action by line shaft, carries out primary attrition crushing to the coal cinder entered.
The further setting of the present invention is: described charging aperture two ends are provided with anti-splashing baffle plate, and anti-splashing baffle plate connects housing by spring.
Adopt technique scheme, can extrude the anti-splashing baffle plate of both sides when coal cinder enters from charging aperture, cause the spring on anti-splashing baffle plate to be stretched, coal cinder directly falls on compression roller simultaneously, and deviation is less, after charging, spring reset, anti-splashing baffle plate returns to original position, can stop the coal splashed in one-level crushing chamber, reduce the waste of coal, operate also safer.
The further setting of the present invention is: described rotation breaker assembly comprises spiral crushing device a, b and spin a, b, one end of described spiral crushing device a, b connects spin a, b respectively, the other end of described spiral crushing device a, b is hinged on line shaft respectively, and described spin a, b engage raceway respectively.
Adopt technique scheme, due to first time broken after coal be extruded as comparatively granule, the edge of two-stage crushing room may be scattered in, when carrying out second time fragmentation, line shaft drives spiral crushing device a, b to be moved in a circle on raceway by corresponding spin a, b, can carry out 360 degree without dead angle fragmentation, simultaneously the coal of edge can carry out fragmentation, the particle of further reduction coal, improves the crushing efficiency of coal, and crushing effect is good.
The further setting of the present invention is: described vibrations metal sieve plate is steel alloy material.
Adopt technique scheme, alloy steel material ductility is good, is easy to processing, metal sieve plate adopts the mode of vibrations that coal can not only be made to drop into coal storeroom, the larger coal of particle can also be made to be kicked up again broken, improve the uniformity of coal particles, the thermal efficiency is high.
